1. PRECAUTIONS FOR USERS WITH PACEMAKERS Weak electric waves are emitted from the key. If a pacemaker is being used, read the pacemaker instruction manual before using the smart key system. If implanted pacemakers or cardioverter defibrillators are being used, make sure they are not brought near the electrical key antenna and indoor electrical key antenna. The electric waves may affect them. If electric devices (for medical purposes) other than an implantable pacemaker or implantable cardioverter defibrillator are used, confirm with the manufacturer if electric waves affect their operation. Electric waves may affect the electric devices. The smart key system can be set so that it does not operate. Refer to Key Cancel for more information. Refer to «CUSTOMIZE PARAMETERS»(ref-422211-S38349874092011092600000) . TEXT IN ILLUSTRATION *1 Electrical Key Antenna *2 Indoor Electrical Key Antenna
2. PRECAUTIONS FOR SMART KEY SYSTEM AND KEY The smart key system does not operate in the following situations. If it does not operate at all, check that the following is not the cause. The key cancel operation has been performed. There is no key battery (key indicator does not blink when key switches are pressed). The key must be in the possession of the user (this is a requirement of the smart key system to make sure the user maintains a habit of carrying the key). As the key only emits weak electric waves, if any of the following conditions are met, the detection area of the key may become smaller or the key may become undetectable. The battery is depleted. There are TV towers, electric power plants, broadcasting stations, gas stations or other areas of strong electric wave output nearby. Wireless products such as cell phones, etc. are carried with the key. The key is covered by or in contact with metal. Electric wave type keyless entry systems are being operated nearby. The key is placed near high-voltage, electric noise emitting equipment. Film with some metallic content is applied to the back glass. HINT: In this case, remove the film or unlock the door using the mechanical key. Even if the key is in the vehicle exterior key detection area, the key may not operate properly due to the vehicle body design. Even if the key is in the vehicle exterior key detection area, the key may not be properly detected if the key is near a window, door handle or bumper. Even if the key is in the vehicle interior key detection area, the key may not be properly detected if the key is on the instrument panel, in the glove box or on the floor. Depending on the way the key is held, the key may not operate properly.
3. PRECAUTIONS WHEN USING TECHSTREAM When troubleshooting the smart key system using the Techstream with the engine switch off, connect the Techstream to the vehicle and turn any of the courtesy light switches on and off until communication between the Techstream and vehicle begins (make sure the interval between on and off operations is less than 1.5 seconds). The reason this procedure is necessary is that when the engine switch is off, the main body ECU may be in sleep mode. When the main body ECU is in sleep mode, communication with the Techstream is not possible. After DTCs are cleared, check if the trouble occurs again 6 seconds after the engine switch is turned on (IG).
4. PRECAUTIONS FOR EACH FUNCTION Precautions for the key: The key is a precision instrument. Be sure to observe the following: Do not drop or strike the key. Do not keep the key in a high temperature area for a long time. Do not use an ultrasonic washing machine to clean the key. Keep the key away from magnets or magnetized items during use. Do not attach any stickers to the key. If a key is lost, clear all registered key ID codes and then register the remaining keys. Precautions for the entry unlock function: As the sensor is built into the backside of the outside door handle, the user must touch the backside part of the handle when performing the unlock function. If the sensor is touched with gloved hands, the response of the door may be delayed. During the entry unlock operation, if the door handle is pulled before the door unlocks, the unlock function cannot be completed. Confirm that the door has been unlocked before pulling the door handle to open the door. Make sure that the doors unlock when touching the unlock sensor on the door outside handle while the key is being carried. If the doors cannot be unlocked, the certification ECU orders the main body ECU to perform the door unlock operation 4 times at intervals of 0.75 seconds. At this time, the door may not be unlocked because the handle is being pulled due to some mechanical reasons. Be sure to return the door handle to its original position. If the door cannot be opened by pulling the handle, perform the entry unlock operation again. If the key is too close to the antenna on the outside of the vehicle, the door may not be unlocked because the key cannot react to the strong wave output from the transmitter. If the key is within the vehicle exterior detection area, the door can be unlocked even when a person other than the person carrying the key holds the door handle. However, the doors other than the door around which a matching code is detected are not unlocked. If the key is within the detection area of the driver side door outside the vehicle, the doors are unlocked when the person carrying the key holds the driver side door handle. However, if any door handle other than that of the driver side door is held, the doors are not unlocked. If a door is not opened after the door unlock operation, the doors automatically lock after approximately 30 seconds. If a large amount of water is applied to the door handle due to a car wash or heavy rain, the key being brought within the vehicle exterior detection area may cause the doors to be unlocked. However, the doors are locked again after approximately 30 seconds if a door is not opened. If the key of the smart key system is used while it is being carried with the key of another smart key system, the time before the entry unlock operation occurs is more than usual. This is not a malfunction. Precautions for the entry lock function: When performing the entry lock operation, touch the lock sensor on the door outside handle. If touched too quickly or lightly, the entry lock may not operate. It is possible that signals output from the indoor electrical key antenna may leak through the window. Also, if the key is too close to an electrical key antenna, the electrical key antenna output signals are too strong and the key cannot respond. As a result, when the key is near the vehicle interior (window, door handle), 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 situation, move the key away from the vehicle interior (window, door handle), perform the entry lock operation and then perform the entry unlock operation. Do not touch the lock sensor while opening or closing the door. If the lock sensor is touched when opening or closing the door while the key is being carried, the door ajar warning buzzer sounds (beeps outside the vehicle for 10 seconds). If the key is on the instrument panel or floor, or in the glove box, the key reminder function may not operate and the key may be locked in the vehicle. Always carry the key. If the key is outside the vehicle but is very close to a window or door handle (the ECU determines that the key is inside the vehicle) and the transmitter or mechanical key is used to lock the doors (entry lock is not used), entry unlock does not operate. To unlock the doors, perform a wireless door unlock operation. The entry lock function operates in this way to prevent the doors from being unlocked by the electrical key antenna without the knowledge of the user. For example, when a user operates the wireless door lock operation from inside the vehicle, radio waves from an electrical key antenna may leak into the vehicle interior and the doors may unlock. To allow the user enough time to check if the doors are locked after performing a door lock operation (entry lock function or wireless door lock operation), the entry unlock function is not permitted for 3 seconds after the door lock operation. Precautions for the entry ignition function: To start the engine system, first depress the brake pedal firmly until the engine switch indicator illuminates green, and then press the engine switch. Be sure to continue depressing the brake pedal until the engine has completely started. When operating the engine switch, firmly press the switch. If the switch is pressed too quickly, power source control and engine system starting may not operate. While driving the vehicle, continuously pressing the engine switch for 3 seconds or more turns off the engine system. Do not touch the engine switch while driving, except in an emergency. Do not touch the engine switch with oily hands. If the vehicle has been in a hot location for an extended period of time, be careful when touching the engine switch. It may be very hot and cause burns. Take care to avoid spilling beverages on the engine switch. Keep all liquids away from the engine switch. Do not use the engine switch if it seems to be sticking or feels abnormal. The vehicle continually records the power source mode [off, on (ACC), on (IG), start]. When the battery cable is disconnected and reconnected, the power source mode returns to the mode it was in before disconnecting the battery cable. Always turn the engine switch off before disconnecting the battery cable. When the vehicle battery is fully depleted, power is cut and the power source mode before the power was cut is unknown, so be extremely careful. Do not connect any electronic products to the ACC, IG1 or IG2 coil side wiring, as the vehicle power supply may be unable to be turned on, or other problems may occur. When the key battery is depleted and the key is held up to the engine switch to start the engine system, the following warning alarms sound. Driver side door is opened and closed: Shift lever in P power source cut reminder exit warning Shift lever not in P power source cut reminder exit warning Door other than driver side door is opened and closed: Occupant leaves with key warning The warning alarms do not indicate an actual malfunction. The alarms sound because the key battery is depleted and the system cannot determine if the key is inside the vehicle or not. With the engine switch on (ACC), the engine can be started by pressing the engine switch for 15 seconds without depressing the brake pedal. Precautions for back door entry unlock function: Even if the key is within the electrical key antenna (outside luggage) detection area, the back door cannot be opened if the key is in the following areas: Near the bumper Too close to the ground or in a high place Precautions for the battery built into the key and the vehicle battery: The key is constantly checking for signals from the vehicle, which requires power from the built-in battery. The life of the battery is approximately 1 to 2 years depending on usage conditions. Also, if the key is in contact with a cell phone while the user walks around (by putting them together into a pocket, etc.), the battery may become significantly depleted. Be sure to replace the battery when its power is low. When replacing the battery, do not touch the inner circuit board or other inner parts. The key is constantly checking for signals from the vehicle and using battery power, whether the key is being used or not. Even if the user is carrying 2 keys and only 1 key is used, both keys consume battery power. If the key continuously receives strong, identical frequency waves, this may drain the key battery. Store the key at least 1 m (3.28 ft.) from TVs, personal computers, chargers for cell phones or other electrical products. When the door is being locked, the vehicle battery is used to transmit radio waves. The battery may be fully depleted if the vehicle remains stopped for a long time. If the vehicle is not used for a long time, remove the battery from the vehicle or cancel the smart key system. When the door is being locked with the key in the detection area of a door electrical key antenna, the battery is used for regular communication between the key and vehicle. If the vehicle is not used, keep the key away from the vehicle (more than 2 m [6.56 ft.]). After disconnecting and reconnecting the battery cable, the entry unlock function may not operate. If this occurs, perform a wireless door unlock and lock operation. When the battery is fully depleted and the engine does not start even after recharging, perform the following: 1) move the shift lever to P, 2) turn the engine switch off, and 3) open and close the driver door. Then start the engine. When starting the engine system after the removal and installation of the vehicle battery, first perform the following: 1) open and close the driver door, and 2) wait 10 seconds or more. When an engine system start is attempted after the above procedures, the engine system does not start. However, this is not a malfunction. The engine system starts normally from the second attempt. Precautions for the entry unlock mode switching function: Use the entry unlock mode switching function within a 1 m (3.28 ft.) radius around the vehicle or from inside the vehicle. After changing modes, it is necessary to wait 5 seconds before the modes can be changed again.

To lock or unlock the doors, insert the key into the door key cylinder, and then turn it to the lock or unlock position. TEXT IN ILLUSTRATION *1 Lock Switch *2 Unlock Switch *3 Panic Switch *4 Mechanical Key Antenna (front door, front floor, rear floor, inside luggage and outside luggage): Each antenna transmits the request signal received from the certification ECU, and forms a key detection area to detect the presence of a key. The detection area formed by the front door antenna and outside luggage antenna is approximately 0.7 to 1.0 m (2.30 to 3.28 ft.) from the outside handle of the front door and rear bumper. The detection area of the front door antenna is formed by transmitting a request signal every 0.25 seconds while the engine switch is off and all the doors are locked. In this way, it detects the proximity of a key. During entry lock, the detection area is formed with the lock sensor on. The detection area of the outside luggage antenna is formed when the unlock switch is on. The detection area of the indoor antennas (front floor, rear floor and inside luggage) is formed when the driver door is open or closed, during starting, when a warning is activated, or when the lock sensor is on.
5. ENTRY FUNCTION OPERATION The smart key system has the following functions. Function Outline Mechanical Key Operation is the same as a conventional mechanical key. Wireless Door Lock Control This function remotely locks and unlocks all the doors and the back door. Operation is the same as the wireless door lock control system. However, the receiver in the certification ECU uses the door control receiver to control locking and unlocking. Entry Unlock When the key is located in the detection area of the electrical key antenna, the door can be unlocked by touching the inside of the front door outside handle. Entry Unlock Mode Switching. Refer to «CUSTOMIZE PARAMETERS»(ref-422211-S38349874092011092600000) Changes the doors that can be unlocked with the entry unlock function between 2 modes.

6. ENTRY UNLOCK FUNCTION The detection area is formed by communication between an electrical key antenna and the certification ECU when the door is locked in order to detect the person carrying the key. When the person carrying the key enters the detection area around the vehicle, the matching of the ID codes for an electrical key antenna and key is automatically performed. After the matching is completed, the door enters unlock standby mode. In unlock standby mode, the electrical key antenna built into the outside handle starts operating. If the outside handle is held (the back side of the handle is touched), the door unlock operation is performed. At this time, the hazard warning lights blink twice. If any of the doors are not opened after a door unlock operation, all the doors automatically lock after 30 seconds.
7. ENTRY LOCK FUNCTION After leaving the vehicle while carrying the key, touch the lock sensor on the outside handle or push the unlock switch on the back door control switch when all the doors are closed. The certification ECU determines whether the key is located inside or outside of the cabin based on the information from an electrical key antenna and indoor electrical key antenna. Then matching of the ID codes is performed. When the matching result shows that the key is not detected inside the vehicle and the ID codes of the key and electrical key antenna match, the door lock function operates. At this time, the hazard warning lights blink once. If the key is located inside of the cabin, the door lock function does not operate and the alarm buzzer (beep sound) sounds for 2 seconds.
8. ENTRY BACK DOOR UNLOCK FUNCTION Stand in front of the back door with the key and push the unlock switch on the back door control switch or back door opener switch to start the matching of the ID codes for the electrical key antenna.
