Back-up programme
A back-up system is in place if a fault should occur in the
control system.
The automatic gearbox switches to the back-up programme if a fault should
occur in the control system. This is indicated by a gear pinion symbol which
lights up on the instrument panel display.
It is still possible to move the selector lever to all positions. The manual
shift programme (tiptronic) is not available when the back-up programme is
active.
Vehicles with tiptronic gearbox: When the selector lever is in position D or S
or in the manual shift programme, the gearbox will remain in 3rd gear if 1st,
2nd or 3rd gears were engaged when the fault occurred. The gearbox will
remain in 5th gear if 4th, 5th or 6th gears were engaged. The gearbox will
then engage 3rd gear when you drive away from a standstill or after the en-
gine is restarted.
It will still be possible to use reverse gear in the normal way. However, the
electronic lock for reverse gear will be switched off.
CAUTION
Should the gearbox ever switch into the back-up programme, you should
take the vehicle to a technical service or qualified workshop as soon as pos-
sible.
Steering wheel with paddle levers
The paddle levers on the steering wheel enable the driver to
manually select pre-programmed ratios or gears.
