the following driving safety systems:

4MATIC (Four Wheel Electronic
Traction System)
ABS
The Antilock Brake System (ABS) regulates
the brake pressure so that the wheels do
not lock during braking. This allows you to
maintain the ability to steer your vehicle.
The ABS is functional above a speed of
approximately 5 mph (8 km/h) indepen-
dent of road surface conditions.
On slippery road surfaces, the ABS will re-
spond even to light brake pressure.
The - indicator lamp in the instrument
cluster comes on when you switch on the
ignition. It goes out when the engine is run-
ning.
iIn winter operation, the maximum
effectiveness of the ABS, the BAS, the
ESP, SBC and 4MATIC is only achieved
with winter tires (M + S tires), or snow
chains as required.Warning!
G
The following factors increase the risk of ac-
cidents:
Excessive speed, especially in turns
Wet and slippery road surfaces
Following another vehicle too closely
The ABS, BAS, ESP, SBC and 4MATIC cannot
reduce this risk.
Always adjust your driving style to the pre-
vailing road and weather conditions.
Warning!
G
Do not pump the brake pedal. Use firm,
steady brake pedal pressure instead. Pump-
ing the brake pedal defeats the purpose of
the ABS and significantly reduces braking
effectiveness.

G
If the exterior lamp switch is set toU,
the headlamps may switch off unexpect-
edly when the system senses bright am-
bient light, for example light from
oncoming traffic.
the headlamps will not be automatically
switched on under foggy conditions.
To minimize risk to you and to others, acti-
vate headlamps by turning exterior lamp
switch toB when driving or when traffic
and / or ambient lighting conditions require
you to do so.
In low ambient lighting conditions, only
switch from positionU toB with the
vehicle at a standstill. Switching fromU
toB will briefly switch off the head-
lamps. Doing so while driving in low ambient
lighting conditions may result in an acci-
dent.
The automatic headlamp feature is only an
aid to the driver. The driver is responsible for
the operation of the vehicle's lights at all
times.
