Battery – Initialisation80A
When removing or disconnecting the battery, check that the battery is working correctly by performing a number of
initialisations on different vehicle functions.
These initialisations do not require a tool of any kind.
Anti-theft code:
–Entering a 4-digit radio or radio navigation code (see 86A, Radio, Radio: Anti-theft code).
–Setting the time on the radio or the radio navigation system:
To set the radio navigation system time, enter the four digit code. Insert the navigation CD-ROM then drive the
vehicle to pick up the satellite signals. It is now possible to set the time (see 86A, Radio, Radio: Setting the time).
Initialisation of the window winders:
–Check that the electric windows are still initialised. The windows should open and close when the switch is pressed.
If this does not happen, re-initialise (see 87D, Electric windows - sunroof, Electric windows: Initialisation).
Initialising the sunroof:
–Check that the sunroof is still initialised. The sunroof should open or close to the requested position without
stopping. If this does not happen, re-initialise (see 87D, Electric windows - Sunroof, Electric sunroof:
Initialisation).
Initialising the electric power assisted steering:
–In order that the electric power-assisted steering recognises the "steering wheel angle" signal, move the steering
wheel from lock to lock with the engine running (see 36B, Power-assisted steering, Replacement of
components).
Initialising the computers:
-The other computers are automatically initialised when the vehicle is being driven. Drive the vehicle for at least
1 minute at a speed greater than 18 mph (30 km/h) so that the tyre pressures are displayed again.
