Driving safety systems
In this section you will find information
on the following driving safety systems:
앫 ABS (Antilock Brake System)
앫 BAS (Brake Assist System)
앫 ESP
®
(Electronic Stability Program)
앫 Electro-hydraulic brake system
i In winter operation, the maximum effec-
tiveness of the ABS, BAS, ESP
®
and electro-hy-
draulic brake system is only achieved with
winter tires (M + S tires), or snow chains as re-
quired.
The Antilock Brake System (ABS) regu-
lates 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
respond even to light brake pressure.
The - indicator lamp in the instru-
ment cluster comes on when you switch
on the ignition. It goes out when the en-
gine is running.
Braking
If the ABS activates during braking, the
ABS/ESP
®
warning lamp v in the in-
strument cluster dial flashes. Because of
the electro-hydraulic brake system, you
will not feel any pulsation in the brake
pedal.
왘 Keep firm and steady pressure on the
brake pedal.
Continuous steady brake pedal pressure
yields the advantages provided by
the ABS, namely braking power and the
ability to steer the vehicle.
The ABS/ESP
®
warning lamp v flashes
whenever the ABS is activated which can
be an indication of hazardous road con-
ditions and functions as a reminder to
take extra care while driving.
Emergency brake maneuver
왘 Keep continuous full pressure on the
brake pedal.
Driving safety systems
Warning! G
The following factors increase the risk of
accidents:
앫 Excessive speed, especially in turns
앫 Wet and slippery road surfaces
앫 Following another vehicle too closely
The ABS, BAS, ESP
®
and electro-hydraulic
brake system cannot reduce this risk.
Always adjust your driving style to the pre-
vailing road and weather conditions.
ABS
Warning! G
Do not pump the brake pedal. Use firm,
steady brake pedal pressure instead.
Pumping the brake pedal defeats the pur-
pose of the ABS and significantly reduces
braking effectiveness.
