80 Safety and SecurityDriving safety systemsIn this section you will find information on
the following driving safety systems:

ABS (A
ntilock B
rake S
ystem)


BAS (B
rake A
ssist S
ystem)


ESP (E
lectronic S
tability P
rogram)
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
respond even to light brake pressure.
The -indicator lamp in the speedome-
ter dial (
page 24) comes on when you
switch on the ignition. It goes out when the
engine is running.
iIn winter operation, the maximum
effectiveness of the ABS, the BAS, and
the ESP is only achieved with winter
tires (M + S tires), or snow chains as
required.
Warning!
G
The following factors increase the risk of
accidents:

Excessive speed, especially in turns


Wet and slippery road surfaces


Following another vehicle too closely
The ABS, BAS, and ESP 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.

82 Safety and SecurityDriving safety systemsFor more information, see “Practical Hints”
(page 351).
ESP
The Electronic Stability Program (ESP) is
operational as soon as the engine is run-
ning and monitors the vehicle’s traction
(force of adhesive friction between the
tires and the road surface) and handling.
The ESP recognizes when a wheel is spin-
ning or if the vehicle starts to skid.
By applying brakes to the appropriate
wheel and by limiting engine output, the
ESP works to stabilize the vehicle. The ESP
is especially useful while driving off and on
wet or slippery road surfaces. The ESP also
stabilizes the vehicle during braking ma-
neuvers.
The ESP warning lampv in the speed-
ometer dial flashes when the ESP is en-
gaged.
The ESP warning lampv in the speed-
ometer dial comes on when you switch on
the ignition. It goes out when the engine is
running.
Warning!
G
The BAS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase braking efficiency beyond that
afforded by the condition of the vehicle
brakes and tires or the traction afforded.
The BAS cannot prevent accidents, includ-
ing those resulting from excessive speed in
turns, following another vehicle too closely,
or hydroplaning. Only a safe, attentive, and
skillful driver can prevent accidents. The ca-
pabilities of a BAS equipped vehicle must
never be exploited in a reckless or danger-
ous manner which could jeopardize the us-
er’s safety or the safety of others.
Warning!
G
Never switch off the ESP when you see the
ESP warning lampv flashing in the
speedometer dial. In this case, proceed as
follows:

While driving off, apply as little throttle
as possible.


While driving, ease up on the accelera-
tor.


Adapt your speed and driving style to
the prevailing road conditions.
Failure to observe these guidelines could
cause the vehicle to skid.
The ESP cannot prevent accidents resulting
from excessive speed.
