The red ABS warning lamp is lit while the engine is running.
The ABS (Anti-lock Braking System) is malfunctioning.
An additional warning tone indicates that EBD (electronic brake force distribution) is malfunctioning.
Other driving and driving safety systems may also be malfunctioning.
G WARNING
The brake system continues to function normally, but without the functions listed above. The front and rear wheels could therefore lock if you brake hard, for exam-
ple.
The steerability and braking characteristics may be severely affected. The braking
distance may increase in an emergency braking situation.
If ESP ®
is not operational, ESP ®
is unable to stabilise the vehicle.
There is an increased risk of skidding and/or accident.
X Observe the additional display messages on the multifunction display.
X Drive on carefully.
X Consult aqualified specialist workshop immediately.
If the ABS control unit is faulty, there is also apossibility that other systems, such
as the navigation system or the automatic transmission, will be unavailable. !
N
The red ABS warning lamp is lit while the engine is running.
ABS is temporarily unavailable.
Other driving and driving safety systems may also be unavailable.
Possible causes:
R self-diagnosis is not yet complete
R the on-board voltage may be insufficient
G WARNING
The brake system continues to function normally, but without the functions listed above. The wheels could therefor elock if you brake hard, for example.
The steerability and braking characteristics may be severely affected. The braking
distance may increase in an emergenc ybraking situation.
If ESP ®
is not operational, ESP ®
is unable to stabilise the vehicle.
There is arisk of an accident.
X Carefully drive on asuitable stretch of road, making gentle steerin gmovements
at speeds of above 20 km/h.
The functions mentioned above are available again when the warning lamp goes out.
If the warning lamp is still on:
X Observe the additional display messages on the multifunction display.

The navigation system calculates the route to
the destination without taking account of the
following, for example:
R traffic lights
R stop and give way signs
R parking or stopping restrictions
R road narrowing
R other road and traffic rule sand regulations
The multimedi asystem may provid eincorrect
navigation announcements if the surroundings
do not correspond to the data on the digital map (for example, aroute may have been diverted or
the direction of aone-wa ystreet may have
changed).
For this reason, you must alwayso bserve road
