Do not place the electrical key transmitter sub-assembly near magnetic equipment, such as digital audio players, induction cookers, medical devices that generate low-frequency electromagnetic waves, etc. Do not attach any stickers to the electrical key transmitter sub-assembly. Do not disassemble the electrical key transmitter sub-assemblies. The mechanical key should only be used in an emergency, such as when the transmitter battery is depleted.
7. PRECAUTIONS WHEN INSPECTING SMART ACCESS SYSTEM WITH PUSH-BUTTON START (for Entry Function) General precaution for the smart access system with push-button start (for Entry Function): Always carry the electrical key transmitter sub-assembly. The smart access system with push-button start (for Entry Function) may not operate normally or the key detection area may decrease in the following situations: The transmitter battery is depleted. There are TV towers, electric power plants, broadcasting stations, gas stations or other facilities that generate strong radio waves or electrical noise nearby. Wireless communication devices, such as walkie-talkies, cell phones, cordless telephones, digital audio players, portable game systems, etc., are carried together with the electrical key transmitter sub-assembly. The electrical key transmitter sub-assembly is covered by or in contact with objects made of metal, such as coins, certain types of cards, etc. Metallic film is applied to the rear window glass. A radio wave type keyless entry system or wireless remote is operated nearby. An electrical key transmitter sub-assembly from another vehicle is nearby. The electrical key transmitter sub-assembly is placed near equipment that generates high-voltage or electrical noise. The electrical key transmitter sub-assembly is placed near an electronic device such as a battery charger. Operating range of the smart access system with push-button start (for Entry Function): Due to the body design, there are some areas in which proper system operation is difficult. Even if the electrical key transmitter sub-assembly is in the vehicle exterior detection area, the electrical key transmitter sub-assembly may not be properly detected if the electrical key transmitter sub-assembly is near a window, a door handle or the center of the bumper. Even if an electrical key transmitter sub-assembly is in a vehicle interior detection area, the electrical key transmitter sub-assembly may not be properly detected if it is on the instrument panel, in the glove box or on the floor. Depending on the way the electrical key transmitter sub-assembly is held, the electrical key transmitter sub-assembly may not operate properly. As weak radio waves are emitted from the electrical key transmitter sub-assembly, if a pacemaker is being used, be sure to read the pacemaker instruction manual. The smart access system with push-button start (for Entry Function) will not operate under the following conditions: The procedure to cancel the smart access system with push-button start (for Entry Function) has been performed. There is no transmitter battery or the transmitter battery is depleted (the LED of the electrical key transmitter sub-assembly does not blink when an electrical key transmitter sub-assembly switch is pressed).
8. PRECAUTIONS FOR ENTRY UNLOCK FUNCTION When unlocking the doors, make sure to grasp the front door outside handle assembly, ensuring contact with the sensor on the inner part of the handle. Pull the handle after confirming that the door has unlocked. If the front door outside handle assembly is grasped with gloved hands, unlocking may be delayed or may not occur. When performing an entry unlock operation, make sure to check that the doors are unlocked before pulling a door outside handle assembly to open a door. When attempting to open a door suddenly or immediately after entering a vehicle exterior detection area, the door may not unlock. In this case the system automatically performs the door unlock operation 4 times. However, if the front door outside handle assembly is being pulled at this time, the door may not unlock due to mechanical reasons. If the door is not unlocked, return the door outside handle to its original position and pull the handle after confirming that the door has unlocked. If the electrical key transmitter sub-assembly is brought too close to the front door outside handle assembly, it may not be possible to unlock the door with the entry unlock function. If an electrical key transmitter sub-assembly is within a vehicle exterior detection area, the door can be unlocked even when a person other than the person carrying the electrical key transmitter sub-assembly grasps the front door outside handle assembly. However, doors other than the door for which the matching code is detected cannot be unlocked (if the electrical key transmitter sub-assembly is in the vehicle exterior detection area of the driver side door and the driver side front door outside handle assembly is held, the doors can be unlocked. However, if the front door outside handle assembly (for front passenger door) is held, the doors cannot be unlocked). After a wireless door lock, manual door lock or key-linked door lock operation is performed with the electrical key transmitter sub-assembly in an interior detection area or near the vehicle, an entry unlock operation cannot be performed. Therefore, when a wireless door lock operation is performed near a window or door handle, the entry unlock may not be able to be operated. To unlock the doors, perform a wireless door unlock operation. If a door is not opened after a door unlock operation, the doors automatically lock after approximately 60 seconds*. If an electrical key transmitter sub-assembly is within a vehicle exterior detection area and a large amount of water is applied to the front door outside handle assembly, such as by a car wash or heavy rain, the sensor may react and the entry unlock operation may be performed. However, the doors will automatically lock after approximately 60 seconds if a door is not opened*. If the electrical key transmitter sub-assembly is being carried together with an electrical key transmitter sub-assembly from another vehicle with a smart access system with push-button start (for Entry Function) and the front door outside handle assembly is held, the time before the door is unlocked by the entry unlock operation may be more than normal. HINT: *: When the auto lock function operates after an entry unlock operation, if an electrical key transmitter sub-assembly is detected in the cabin, the doors will be unlocked by the door ajar warning function.
9. PRECAUTIONS FOR ENTRY LOCK FUNCTION When performing an entry lock operation, if the lock sensor on the front door outside handle assembly is touched too quickly, the door may not lock. If the electrical key transmitter sub-assembly is brought near the vehicle interior (window, front door outside handle assembly), the entry lock function may not operate. Also, the key reminder warning buzzer may sound and the entry unlock operation may stop functioning. In this case, move the electrical key transmitter sub-assembly away from the vehicle interior (window, front door outside handle assembly), perform an entry lock operation, and then perform an entry unlock operation. If the electrical key transmitter sub-assembly is left on the instrument panel, in the glove box or on the floor, the key reminder warning function may not operate and the electrical key transmitter sub-assembly may be locked in the vehicle when a door lock operation is performed. Always carry the electrical key transmitter sub-assembly. The entry unlock operation cannot be performed for approximately 3 seconds after an operation that locks the doors, such as an entry lock or wireless lock operation, is performed. When checking an entry lock operation several times, it can only be performed up to 2 times consecutively depending on the setting. To perform the operation 3 times or more consecutively, the doors need to be unlocked once (any unlock operation is acceptable). However, this is only for an entry lock operation, other door lock operations, such as a wireless door lock operation, can be performed consecutively.

1. MULTI CHANNEL FUNCTION The electrical key transmitter sub-assembly and door control and tire pressure monitoring system receiver assembly can operate on two different RF channels. When an electrical key transmitter sub-assembly is brought within an exterior detection area, key verification begins. If key verification fails due to wave interference, the channel will be switched and key verification will be performed again. The multi channel system begins verification using the channel on which the last verification was successfully performed. When verification fails, the system switches to the other channel. *a Exterior detection areas are created using LF waves (emitted from the vehicle at intervals of 0.25 seconds) to receive a response from the electrical key transmitter sub-assembly. *b When the electrical key transmitter sub-assembly is brought into an exterior detection area, it receives LF waves from the vehicle. Using RF waves, the electrical key transmitter sub-assembly responds to the vehicle. *c Upon receiving the response from the electrical key transmitter sub-assembly, the certification ECU (smart key ECU assembly) activates the electrical key antennas (outside) one by one. Using LF waves, the certification ECU (smart key ECU assembly) determines which exterior detection area the electrical key transmitter sub-assembly is in. *d The electrical key transmitter sub-assembly receives the LF waves from the vehicle and responds using RF waves. (The certification ECU (smart key ECU assembly) recognizes which exterior detection area the electrical key transmitter sub-assembly is in.) *e The certification ECU (smart key ECU assembly) sends registered key ID information to the electrical key transmitter sub-assembly using LF waves. (Up to 7 key IDs can be registered.) *f The electrical key transmitter sub-assembly sends the key ID information using RF waves. When the certification ECU (smart key ECU assembly) receives it, verification completes. *g Wave interference (Channel switching) - - The multi channel system changes the channels when the RF band (*b, *d and *f) is interrupted by wave interference. Refer to the table below to confirm when the system changes the channels. *b or *d is NG *f is NG Condition RF waves cannot be received RF waves cannot be received properly RF waves cannot be received RF waves cannot be received properly Channel switching The channels will not be switched. The channels will be switched. The channels will not be switched. The channels will be switched*. *: The channels are not switched during vehicle interior verification after an entry lock operation is performed. HINT: When the channels are switched, the history will be stored in the certification ECU (smart key ECU assembly). This history can be read using the Techstream. Refer to «OPERATION HISTORY LIST [04/2013 - ]»(ref-665863-S08594883702014102400000)

6. DIAGNOSIS IN ACCORDANCE WITH USER OPERATION Operation 1 Operation Turn the engine switch off and lock all the doors, then take the electrical key transmitter sub-assembly approximately 3 m (9.84 ft.) or more away from the vehicle. HINT: The detection area of each electrical key antenna (outside) is formed by emitting a periodic LF band request signal every 0.25 seconds. The detection area formed by each front door outside handle assembly (electrical key antenna) has a detection range of approximately 0.7 m (2.30 ft.). Waveform or Output Value Pulse generation (K6-4 (CLG1) - K6-11 (E)*) *: Refer to «TERMINALS OF ECU [04/2013 - ]»(ref-665538-S39375458662014102400000) Operation 2 Operation Bring the electrical key transmitter sub-assembly within 0.7 m (2.30 ft.) of the driver door. HINT: The system is in unlock standby mode when the electrical key transmitter sub-assembly is in the detection area and the key ID code sent by the electrical key transmitter sub-assembly matches the key ID code stored by the certification ECU (smart key ECU assembly). The door unlocks if the unlock sensor is touched by hand with the system in unlock standby mode. Signal transmission: Certification ECU (smart key ECU assembly) --> Front door outside handle assembly (electrical key antenna) --> Electrical key transmitter sub-assembly --> Door control and tire pressure monitoring system receiver assembly --> Certification ECU (smart key ECU assembly) --> Main body ECU (multiplex network body ECU) Expected operation of the vehicle The electrical key transmitter sub-assembly LED starts blinking. If it does not, check the suspected areas in the following table. Waveform or Output Value Pulse generation (K6-4 (CLG1) - K6-11 (E)*) Pulse generation (K5-18 (RCO) - K6-11 (E)*) Pulse generation (K5-20 (RDAM) - K6-11 (E)*) Pulse generation (K5-19 (CSEL) - K6-11 (E)*) *: Refer to «TERMINALS OF ECU [04/2013 - ]»(ref-665538-S39375458662014102400000) Suspected Area Diagnosis Electrical key transmitter sub-assembly The key ID code sent by the electrical key transmitter sub-assembly does not match the key ID code stored in the certification ECU (smart key ECU assembly). Use another electrical key transmitter sub-assembly to check the operation. If the LED of the electrical key transmitter sub-assembly does not blink when it is brought within 0.7 m (2.30 ft.) of the driver door, perform the following procedure. Press the lock and unlock switches of the electrical key transmitter sub-assembly to check the operation. If the doors can be locked and unlocked, that means the detection area has not been formed. Parts other than the electrical key transmitter sub-assemblies and front door outside handle assemblies may be malfunctioning. If the electrical key transmitter sub-assembly malfunctions, the engine cannot be started and the engine switch cannot be turned on (ACC or IG). Under normal operation, "ACCESSORY" or "IGNITION ON" is displayed on the multi-information display in the combination meter assembly when the engine switch is pressed with the electrical key transmitter sub-assembly in the driver seat area, the shift lever in P and the brake pedal released. If the door cannot be opened, use the mechanical key installed in the electrical key transmitter sub-assembly to open the door. HINT: Before replacing the electrical key transmitter sub-assembly, check if the transmitter battery is depleted. If the door cannot be opened, use the mechanical key installed in the electrical key transmitter sub-assembly to open the door. Transmitter battery is depleted Press and hold the lock switch of the electrical key transmitter sub-assembly for 5 seconds and check the number of times that the transmitter LED blinks. If the transmitter LED does not blink or blinks only once or twice, the transmitter battery may be depleted. If the transmitter LED does not blink at all, the electrical key transmitter sub-assembly may be malfunctioning. If the transmitter battery voltage at the time the electrical key transmitter sub-assembly sends a signal drops to 2.2 V or less, "Yes" is displayed for "Key Low Battery" in the Data List. If the transmitter battery voltage drops to 2.0 V or lower, operation cannot be assured. HINT: The output of the electrical key transmitter sub-assembly will decrease if it is in low temperatures. When the transmitter battery is depleted, the engine cannot be started and the engine switch cannot be turned on (ACC or IG). If the electrical key transmitter sub-assembly is held near the engine switch, the engine can be started. Make sure that the transmitter battery type and installation direction are correct. Wave Interference If the problem occurs in certain locations or times of day, the possibility of wave interference is high. When the electrical key transmitter sub-assembly is malfunctioning, the transmitter battery is depleted, an electrical key transmitter sub-assembly from another vehicle has been used or wave interference is suspected. "Yes" may be displayed for any of the following Data List items: "Unmatch Code or Form", "No Response", "ID Code Difference" or "Unmatched Vehicle-ID" Certification ECU (smart key ECU assembly) - Front door outside handle assembly Vehicle exterior detection area is not formed properly. If the electrical key transmitter sub-assembly LED does not blink within 0.7 m (2.30 ft.) of the front door outside handle assembly of the driver door, but blinks within 0.7 m (2.30 ft.) of the front passenger door, the front door outside handle assembly of the driver door may be malfunctioning. Even if the vehicle exterior detection area is not formed properly, the engine switch can be turned on (ACC) and the engine can be started. Formation of the vehicle exterior detection area can be confirmed by using the Techstream. Refer to «OPERATION CHECK [04/2013 - ]»(ref-665538-S06841953002014102400000) Even if the vehicle exterior detection area is not formed properly, the doors can be unlocked by pressing the unlock switch of the electrical key transmitter sub-assembly. Door Control and Tire Pressure Monitoring System Receiver Assembly If the door control and tire pressure monitoring system receiver assembly is malfunctioning, it is not possible to unlock the front passenger door.

If the door control and tire pressure monitoring system receiver assembly is malfunctioning, the engine cannot be started and the engine switch cannot be turned on (ACC or IG) unless in an emergency. Formation of the vehicle exterior detection area can be confirmed by using the Techstream. Refer to «OPERATION CHECK [04/2013 - ]»(ref-665538-S06841953002014102400000) Vehicle Battery is discharged It may be possible to tell whether the vehicle battery is discharged by operating the horn. Others If the smart access system with push-button start function has been canceled through the customize function, the detection area cannot be formed, therefore the electrical key transmitter sub-assembly LED will not blink even if the electrical key transmitter sub-assembly is brought near a front door outside handle assembly. In the smart access system with push-button start, if the electrical key transmitter sub-assembly is constantly in the exterior detection area of one of the doors, the transmitter battery could be drained. For this reason, if this state continues for longer than 10 minutes, the smart access system with push-button start automatically deactivates the exterior detection area that the electrical key transmitter sub-assembly is in. If the electrical key transmitter sub-assembly is in transmitter battery saving mode, even if it receives LF waves from the vehicle, it does not respond using RF waves, therefore the electrical key transmitter sub-assembly LED does not blink. If the electrical key transmitter sub-assembly is left in the vehicle and the doors are locked using another electrical key transmitter sub-assembly, the electrical key transmitter sub-assembly LED will not blink even if it is brought near a front door outside handle assembly. Operation 3 Operation Touch the unlock sensor of the driver door with the electrical key transmitter sub-assembly in the exterior detection area. Expected operation of the vehicle While the doors are unlocked, the answer-back is performed at the same time. If they do not, check the suspected areas in the following table.

7. VEHICLE BATTERY SAVING FUNCTION When the smart access system with push-button start is operating, the vehicle performs key detection operations every 0.25 seconds. Therefore, if the vehicle is left as is for a long period of time, the vehicle battery may become fully discharged. The following controls help reduce the rate at which the vehicle battery is discharged. If the smart access system with push-button start is not operated for 5 days or more, periodic signal transmission from the electrical key antennas stops. However, the doors can still be unlocked by touching the unlock sensor of a front door outside handle assembly. If the smart access system with push-button start is not operated for 14 days or more, the lock and unlock sensors of the front passenger door outside handle assembly are disabled. Therefore, only the unlock sensor of the front door outside handle assembly of the driver door can be used to unlock the doors.
