If the warning light illuminates after you switch on the ignition, seek assis-
tance from a specialist garage.
If the warning light
or also the warning light
illuminates and an acoustic
signal sounds, this means that the automatic gearbox has overheated.›
Stop and allow the transmission to cool down or drive more quickly than
20 km/h (12 mph).
If the warning light
illuminates repeatedly , park the vehicle, shut off the en-
gine and allow the gearbox to cool down.
Further information » page 80, Automated transmission .
Power steering
Read and observe
on page 34 first.
If the warning light
or
illuminates while driving or after switching on the
ignition does not extinguish, there is an error in the electromechanical power
steering.
If the indicator light
illuminates, this indicates a
complete failure of the
power steering and the steering assist has failed (significantly higher steering
forces).
If the indicator light
illuminates, this indicates a
partial failure of the power
steering and the steering forces can be greater.
›
Stop the car, turn the ignition off and on again.
If the indicator light does not illuminate after the engine has been turned on
again, the power steering is fully operational again.
If the warning light illuminates again, then immediately obtain assistance from
an authorised dealer.
Note
If the vehicle's battery has been disconnected and reconnected, the warning
light illuminates after switching on the ignition. If the warning light does
not extinguish after moving a short distance, this means there is an error in
the system. Seek assistance from a specialist garage immediately. Electronic Stability Control (ESC)
Read and observe
on page 34 first.
The warning light
flashes to show that the ESC is currently operating.
If the warning light
illuminates , there is a fault in the ESC. Seek assistance
from a specialist garage immediately.
As the ESC operates in conjunction with the ABS, the ESC warning light will al-
so come on if the ABS system fails.
If the warning light
illuminates immediately after you start the engine, the
ESC might be switched off due to technical reasons.
›
Switch the ignition off and on again.
If the indicator light
does not illuminate after you switch the engine back
on, the ESC is fully functional again.
Further information » page 84, Electronic Stability Control (ESC) .
Note
If the vehicle's battery has been disconnected and reconnected, the warning
light illuminates after switching on the ignition. If the warning light does
not extinguish after moving a short distance, this means there is an error in
the system. Seek assistance from a specialist garage immediately.

Read and observe
on page 34 first.
The warning light
flashes it shows that the TCS currently operating.
If the warning light
illuminates permanently, there is a fault in the TCS.
Seek assistance from a specialist garage immediately.
The fact that the TCS operates together with the ABS means that the TCS
warning light will also come on if the ABS system is not operating properly.
If the warning light
illuminates immediately after you start the engine, the
TCS might be switched off due to technical reasons.
›
Switch the ignition off and on again.
If the warning light

Manually deactivating/activating the system
90The START-STOP system (hereinafter referred to as the system) saves fuel and
reduces polluting emissions and CO 2 emissions by turning the engine off, e.g.
when stopping at traffic lights, and starting the engine again when moving off.WARNING■ Never let the vehicle roll with the engine switched off.■The brake servo unit and power steering only operate if the engine is run-
ning.
Operating conditions of the system
Fig. 87
Above: Engine is automatically
switched off / down: automatic
cut off is not possible
Read and observe on page 88 first.
For system-dependent automatic engine shutdown
to work, the following conditions must be met.
The driver's door is closed.
The driver has fastened the seat belt.
The bonnet is closed.
The driving speed was higher than 4 km/h after the last stop.
Some additional conditions for the system to function correctly cannot be in-
fluenced or recognised by the driver. Therefore, the system can react differ-
ently in situations which are identical from the driver's perspective.
If, after stopping the vehicle, the check icon
» Fig. 87 appears on the display,
then the conditions for automatic engine shutdown are not met.
Running the engine is essential for the following reasons, for example.
› The engine temperature for the proper function of the system has not yet
been reached.
› The charge state of the vehicle battery is too low.
88Driving
›The current consumption is too high.
› High air-conditioning or heating capacity (high fan speed, big difference be-
tween the desired and actual interior temperature).
Note
■ If the vehicle remains outdoors for a long time in minus temperatures or in
direct sunlight, it can take several hours until the internal temperature of the
vehicle battery reaches a suitable temperature for proper operation of the
START STOP system.■
If the driver's seat belt is removed for more than approx. 30 seconds or the
driver's door is opened during stop mode, the engine will have to be started
manually.
■
After the manual engine start and with a manual gearbox the automatic en-
gine shutdown can take place only when a minimum distance required for the
system function has been covered.
Operation in vehicles with manual gearboxes

For more information about automated manual transmission
The automatic engine shut down takes place when the selector lever is in po-
sitions D, N , and in Tiptronic mode.
If the engine is off due to the automatic and the selector lever is put to the R
position then the automatic starts the engine.
If the gear selector is moved from position R to the position D or N the vehicle
must reach a speed of more than 10 km/h before the automatic engine shut-
down starts.
There is no automatic engine shutdown when the system detects a vehicle
moving due to a large steering angle.
No automatic engine shutdown takes place when the vehicle is moving at low
speed (e.g. during a traffic jam or when tuning) and remains stationary after
pressing the brake pedal lightly. Automatic engine shutdown takes place if you
press the brake pedal down with more force.
System related automatic start-up
Read and observe
on page 88 first.
When the engine is off, the system can automatically start the engine before
the desired journey continues. Some possible reasons for this are:
› The vehicle begins to roll, e.g. on a slope.
› The brake pedal has been actuated several times.
› The current consumption is too high.
