Safety First Operating instructions Tips and Maintenance Technical Data
On braking sharply on slippery ground, this system helps to keep the vehicle
under control, as the wheels do not lock.
However, ABS will not necessarily guarantee shorter braking distances in all
conditions. The braking distance could even be longer if you brake on gravel
or on fresh snow covering a slippery surface.
WARNING
Try to always adapt the speed of the vehicle to weather, road and traffic
conditions. Do not let the extra safety afforded by the system tempt you
into taking any risks when driving. Risk of accident.
• The anti-lock brake system cannot defy the laws of motion. Slippery
and wet roads are dangerous even with ABS! If you notice that the ABS has
been activated, you should reduce speed immediately to suit the road and
traffic conditions.
• The ABS cannot reduce the risk of accident if, for example, you are
driving with an unsuitable load or too close to the preceding vehicle.
• Modifications to the vehicle or work carried out incorrectly (e. g. to the
engine, the brake system, running gear or any components affecting the
wheels and tyres) could affect the efficiency of the ABS, EDL, ESP and TCS
and lessen their efficiency.
• The effectiveness of ABS is also determined by the tyres fitted
⇒ page 224.
ABS warning lamp
The warning lamp monitors the ABS.
The warning lamp should light up for a few seconds when the ignition is
switched on. It goes out again after the system has run through an automatic
test sequence.
There is a fault in the ABS if:
• The ABS warning lamp does not light up when the ignition is switched
on.
• The warning lamp does not go out again after a few seconds.
• The warning lamp lights up when the vehicle is moving.
The vehicle can still be braked in the normal way (except that the ABS control
function is out of action). Please take the vehicle to a qualified workshop as
soon as possible.
If a fault occurs in the ABS, the ESP warning lamp will also light up.

Brake system fault
If the ABS warning lamp lights up together with the brake warning lamp
, this indicates not only a fault in the ABS function, but also a possible fault
in the brake system ⇒ .
At the same time, a text message or the necessary operations may appear on
the instrument panel.
WARNING
Special care must be taken when working on the engine or on components
in the engine compartment.
• It is important that you read and observe the corresponding warnings
before working in the engine compartment ⇒ page 208.
• If the brake warning lamp should light up together with the ABS
warning lamp , stop the vehicle immediately and check the brake fluid
level in the reservoir ⇒ page 220. If the fluid level has dropped below the
“MIN” mark you must not drive on. Risk of accident. You should obtain
professional assistance.
• If the brake fluid level is correct, the fault in the brake system may have
been caused by a failure of the ABS control function. This could cause the
