Instruments, Alarm System: Other Porsche Cayenne I

Connecting and disconnecting battery

> Protective goggles must be worn at all times when working on the battery.

> Do not disconnect battery with engine running.

> Disconnect and reconnect battery with extreme caution. Risk of short circuit and explosion.

> Do not tilt battery when removing it. Risk of acid burns as a result of emerging acid.

> Do not rub the battery with a dry cloth. Risk of explosion as a result of static charge.

> All loads must be switched off beforehand!

> Never start engine without securely connected battery!

> Do not use a boost charger to start the engine!

> Whenever possible, use jump leads with overvoltage protection!

> Always disconnect and cover both battery terminals before carrying out welding work on the vehicle!

> For vehicles with auxiliary battery, also disconnect and cover both terminals of this battery before carrying out welding work!

> Always pull off or push on the wiring harness plugs of control units or other electronic components when the ignition is switched off.

Note. The battery is located in the battery case under the left front seat. For vehicles with a Vehicle Tracking System (VTS), please read the --> 906323 Vehicle Tracking System (VTS) TI!

Effect of disconnection or total discharge of battery on electrical systems in the vehicle and the precautions to be taken

Note. Control unit memories Values and faults stored in the control units can be deleted if the battery is disconnected or completely discharged. If possible, all fault memories should be checked and, if necessary, printed out before the battery is disconnected.

Note. Supply voltage fault entry The entry "supply voltage" may be stored in various control units if the battery has been completely discharged. Delete the "supply voltage" entry from the control units in question.

Note. Ready status In some countries (presently the U. S. A. and Canada), after disconnecting the battery, it is necessary to reach the Ready status by a test drive and/or by using the Porsche System Tester DME control module menu). If in doubt about this, contact the relevant importer. 2470 DME control module With all DME systems, the engine must run for several minutes before the engine control module can relearn the idle speed and mixture adaptation values! After disconnection of the power supply, the idle speed might change or fluctuate briefly until the throttle valve adjusting unit has been readapted. The mixture adaptation is also lost. After the battery is connected: With the DME, it is necessary to carry out a learning and adaptation routine as described below: Switch ignition on for 30 seconds without starting the engine. Do not actuate accelerator pedal.

This completes the adaptation of the throttle valve adjusting unit.

Note. Tire pressure monitoring system When the battery is disconnected and connected, the tire pressure is first displayed as "- - - ". Once the battery has been disconnected and work is complete, the vehicle must be driven for a short distance.

The actual pressures will then be displayed again.

Note. 4560 Steering angle sensor The steering angle sensor must be re-initialized when the battery is disconnected and connected. Turn wheels to straight-ahead position. Switch ignition off and then on again twice. Start engine. From the straight-ahead position, turn steering wheel approx. 20° to the right, past the straight-ahead position. Drive the vehicle straight ahead for at least one second at a speed above 4 km/h (2.5 mph).

The steering angle sensor segment is recognized again in this process.

Once the sensor has been successfully initialized, the fault code that is stored in the fault memory is documented using the fault deletion counter. The fault memory erases itself automatically.

The PSM indicator light in the instrument cluster goes out.

Note. 6014 Electric motor for sliding roof, Panorama roof system The limit positions of the large roof are deleted from the control unit when the battery is disconnected and connected. Switch on ignition. Press rocker switch upward.

The roof opens and closes completely.

The limit positions of the large roof are now stored in the control unit again.

Note. 6452 Power windows The limit positions of the power windows are deleted from the control unit when the battery is disconnected and connected. Perform the following procedure for all power windows: Pull rocker switch and fully close window once. Pull rocker switch once more. Press rocker switch and fully open window once. Press rocker switch once more.

The upper end position of the window is stored.

The lower end position of the window is stored.

Note. 9025 Instrument cluster Clock The time is deleted when the power supply is disconnected. The clock is set in the multi-function display. Press clock button on instrument cluster. Set the time in "Hours" with rocker switch on the wiper switch. Press reset switch on the wiper switch. Set the time in "Minutes" with rocker switch on the wiper switch. Press reset switch on the wiper switch.

Effects of overvoltage on electrical and electronic systems during welding work and the precautions to be taken

> Disconnect and cover both battery terminals before carrying out welding work on the vehicle! Refer to 27 06 19 Removing and installing battery - as of MY 2003 (All Models) . Refer to 27 06 19 Removing and installing battery - as of MY 2004 (Cayenne TIP, Cayenne MAN) .

> For vehicles with auxiliary battery, also disconnect and cover both terminals of this battery before carrying out welding work! Refer to 27 07 19 Removing and installing auxiliary battery - as of MY 2003 (Cayenne TIP, Cayenne MAN, Cayenne S TIP, Cayenne S MAN, Cayenne Turbo) .

> Risk of triggering of airbag modules! Before starting welding work, the airbag triggering unit must be disconnected from the vehicle electrical system by pulling off the plug. Refer to 69 53 19 Removing and installing triggering unit for airbag - as of MY 2003 (All Models) .

> During electric arc welding (e. g. gas shielded arc welding), high currents and voltages flow; these are greater than the vehicle voltage and can lead to the damage or destruction of electrical and electronic components. To keep the risk of damage as low as possible, the ground lead must be clamped as near as possible to the welding area.

> Once complete, install the airbag triggering unit. Refer to 69 53 19 Removing and installing triggering unit for airbag - as of MY 2003 (All Models) ., then the battery. Refer to 27 06 19 Removing and installing battery - as of MY 2003 (All Models) .
