General notes
If the automated transmission shift system is
malfunctioning, you may, under certain circum-
stances, be able to continue your journey in
backup drive mode. It is not possible to change
gear in backup drive mode when the vehicle is in
motion.
The vehicle may respond abnormally in backup
drive mode and therefore requires a high level of
concentration on the part of the driver.
Backup drive mode remains switched on for as
long as the ignition lock is in the drive position.
When you take the key out of the ignition lock,
backup drive mode is switched off. If backup
drive mode is used when the transmission is
cold, the on-board computer may not show the
selected gear. Repeat the gear selection. If the
on-board computer does not display the selec-
ted gear after you have tried to select a gear
several times, switch off the engine. Start the
engine again and select the gear.
