The warning lights in the instrument cluster 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.
The warning lights are located at the following positions in the instrument
cluster » Fig. 17 on page 28 .

5WARNING■ 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 light system » page 61. Place the warning triangle at the prescri-
bed distance.

An acoustic signal will sound if you drive the vehicle above 6 km/h while the
handbrake is still on.
▶ Release the handbrake.
Braking system
Read and observe
on page 31 first.
illuminates – the brake fluid level in the brake system is too low.
▶ Park the vehicle,
stop driving! Seek help from a specialist garage.
WARNINGA fault to the braking system can increase the vehicle's braking distance -
There is risk of accident!
Front seat belt indicator light
Read and observe
on page 31 first.
lights up - the driver or front passenger has not fastened their seat belt.
At a speed of over 20 km/h, the indicator light flashes and an audible warn-
ing sounds at the same time.

Read and observe
on page 31 first.
lights up or flashes – the coolant temperature is too high or the coolant lev-
el is too low.
▶ Stop the vehicle, switch off the engine, and allow the engine to cool down.
▶ Check the coolant level » page 146, Checking and refilling .
If the coolant level is within the specified range and the warning light lights
up again, there may be a malfunction of the cooling fan.

32Using the system
Stability control (ESC) / Traction control (TCS)Read and observe
on page 31 first.
If your vehicle is equipped with the ESC system, the TCS is part of the ESC sys-
tem.
flashes – the ESC or TCS is currently active.
System fault
lights up – there is an ESC or TCS fault.
▶ Continued driving is possible with appropriate caution. Seek assistance from
a specialist garage immediately.
If the warning light comes on after starting the engine, the TCS may be
switched off for technical reasons. ▶ Switch the ignition off and on again.
If the warning light does not illuminate after you switch the engine back on,
the ASR is fully functional again.
Disconnecting the vehicle battery
If the vehicle's battery has been disconnected and reconnected, the warning light comes on after switching on the ignition.
The warning light should go out after driving a short distance.
If, after a short drive, the indicator light does not go out, there is a system er- ror.
▶ You can drive on, exercising appropriate caution. Seek assistance from a spe-
cialist garage immediately.

on page 31 first.
illuminates – the TCS system is disabled.
Anti-lock braking system (ABS)
Read and observe
on page 31 first.
lights up – there is an ABS fault.
The vehicle will only be braked by the normal brake system without the ABS.
▶ Continued driving is possible with appropriate caution. Seek assistance from
a specialist garage immediately.WARNING■ If the warning light lights up together with the warning light
» page 32 , stop driving! Seek help from a specialist garage.■
A fault to the ABS system or the braking system can increase the vehi-
cle's braking distance – risk of accident!
Rear fog light
Read and observe
on page 31 first.
lights up – the rear fog light is switched on.
Lamp failure
Read and observe
on page 31 first.

the tyre pressure monitoring system.
▶ Stop the vehicle, turn the ignition off and start the engine again.
If the warning light flashes again after the engine has started, there is a
system error.
▶ Continued driving is possible with appropriate caution. Seek assistance from
a specialist garage immediately.
Disconnecting the vehicle battery

a specialist garage immediately.
Other incidents
The following reasons can explain the warning light being illuminated.
▶ The vehicle is loaded on one side. Distribute the load evenly.
▶ 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.
CAUTION
