The warning lights indicate certain functions or faults.
Some warning lights can be accompanied by acoustic signals and messages in
the display of the instrument cluster.
After switching on the ignition, some warning lights light up briefly as a func-
tion test.
If the tested systems are OK, the corresponding warning lights go out a few
seconds after switching on the ignition or after starting the engine.
WARNING■ Ignoring illuminated warning lights and related messages or instructions
in the display of the instrument cluster may lead to serious personal injury
or damage to the vehicle.■
If you have to stop for technical reasons, then park the vehicle at a safe
distance from the traffic, switch off the engine and switch on the hazard
warning lights » page 68. The warning triangle must be set up at the pre-
scribed distance - observe the national legal provisions when doing so.

The warning signal is switched of and the indicator light is
permanently lit if
the driver and front passenger have not fastened their seat belts within the
next 90 seconds.
35Instruments and Indicator Lights
If the warning light flashes again after the engine has started, there is a
system error.
Seek help from a specialist garage.
The following reasons can explain the warning light
being illuminated.
› The vehicle is loaded on one side. Distribute loads as evenly as possible.
› The wheels of one axle are loaded more heavily (e.g. when towing a trailer or
when driving uphill or downhill).
› Snow chains are mounted.
› A wheel has been changed.

roads) the warning light can be delayed or does not light up at all.
Note
If the vehicle's battery has been disconnected and reconnected, the warning
light comes on after switching on the ignition. If the indicator light does not
go out after moving a short distance, this means that there is an error in the
system. Seek help from a specialist garage.

Read and observe
on page 35 first.
If the windscreen washer fluid level is too low, the warning light
illumi-
nates .

Cruise Control System
Introduction
This chapter contains information on the following subjects:
Functioning
154
Operating Description
154
The Cruise Control System (CCS) maintains a set speed without you having to
actuate the accelerator pedal.
The state where the GRA maintains the speed is referred to hereinafter as the
control .
WARNING■
The GRA only serves to support and does not relieve the driver of the re-
sponsibility for the vehicle operation.■
Always adjust the speed and driving style to the current visibility, weath-
er, road and traffic conditions.
Functioning
Read and observe
on page 154 first.
Basic requirements for start of control The GRA is activated.
On vehicles with a manual transmission , the second gear or higher must
be engaged.
On vehicles with an automatic gearbox, the selector lever must be in the
D or S position, or in the Tiptronic position.
The current speed must be higher than 20 km/hr.
This is only possible within the range which is permitted by the power output and braking power of the engine.
WARNINGIf the engine power and engine braking effect is insufficient to maintain
the set speed, vehicle operation must be taken over!

If no speed stored, the current speed is adopted.
154Driving
After starting the system, the current speed is stored and the instrument clus-
ter lights up the warning light .
After the interruption in control, the stored speed can be resumed by pressing
the B
button.
Automatic control interruption
Automatic control interruption occurs if any of the following conditions are
met.
› By pressing the brake or clutch pedal.
› When one of the brake assist systems (e.g. ESC) intervenes.
› Through an airbag deployment.
WARNING■
Always deactivate the cruise control system after use to prevent the sys-
tem being switched on unintentionally.■
Control may only be resumed if the stored speed is not too high for the
current traffic conditions.
Note
During control, speed can be increased by pressing the accelerator pedal. Re-
leasing the accelerator pedal will cause the speed to drop again to the set
speed.

157
The 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. 144
Maxi DOT display: Engine is auto-
matically switched off / automat-
ic engine cut off is not possible
Read and observe on page 155 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.
No trailer is coupled.
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 car, the message START-STOP NOT POSSIBLE appears in
the segment display or the
» Fig. 144 check mark appears in the MAXI DOT
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.
› 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).
