Continuous steady brake pedal pressure
yields the advantages provided by the ABS,
namely braking power and ability to steer
the vehicle.
On slippery road surfaces, the ABS will re-
spond even with light brake pressure. The
pulsating brake pedal can be an indication
of hazardous road conditions and func-
tions as a reminder to take extra care while
driving.ABS control
The
-
malfunction indicator lamp in
the instrument cluster lights up when you
turn the key in the steering lock to
position2. It goes out when the engine is
running.
More information can be found in the
“Practical hints” section (
page 196).
iTo alert following vehicles to slippery
road conditions you discover, operate
your hazard warning flashers as appro-
priate.
Warning!

The ABS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase braking or steering efficiency be-
yond that afforded by the condition of the
vehicle brakes and tires or the traction. The
ABS cannot prevent accidents, including
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 an ABS 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.
68 Safety and SecurityDriving safety systemsBAS
The Brake Assist System (BAS) operates in
emergency situations. If you apply the
brakes very quickly, the BAS automatically
provides full brake boost, thereby poten-
tially reducing braking distance. Apply con-
tinuous full braking pressure until the
emergency braking situation is over. The
ABS will prevent the wheels from locking.
When you release the brake pedal, the
brakes function again as normal. The BAS
is then deactivated.
The malfunction indicator lamp for the ESP
is combined with that of the BAS.

ESP
The Electronic Stability Program (ESP)
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 ap-
plying 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 slip-
pery road surfaces.

in the speed-
ometer dial flashes when the ESP is en-
gaged.

The BAS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase braking efficiency beyond that af-
forded by the condition of the vehicle brakes
and tires or the traction. The BAS cannot
prevent accidents, including those resulting
from excessive speed in turns, following an-
other vehicle too closely, or hydroplaning.
Only a safe, attentive, and skillful driver can
prevent accidents. The capabilities of a BAS
equipped vehicle must never be exploited in
a reckless or dangerous manner which
could jeopardize the user’s safety or the
safety of others.

Never switch off the ESP when you see the
ESP warning lamp

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 accelerator
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.

cle. The indicator lamp in the switch for the
tow-away alarm (
page 72) will then
blink.

The alarm system is disarmed when you
unlock your vehicle with the remote con-
trol.
