Functions of ABS (anti-lock braking sy stem)
ABS regulates the brake pressure in critical driv‐
ing situations:
RDuring braking, e.g. at maximum full-s top
braking or insuf ficient traction of the tires,
th e wheels are pr evented from blocking.
RVe hicle steerability while braking is ensured.
If ABS inter venes when braking, youwill feel a
pulsing in the brake pedal. The pulsating brake
pedal can be an indication of hazardous road
conditions and can ser veas a reminder totake
ex tra care while driving.
Sy stem limitations
RABS is active from speeds of appr ox. 5 mph
(8 km/h).
RABS may be impaired or may not function if a

ph ysical limits:
RWhen pulling away on a wet or slippe ryroad.
RWhen braking.
RIn stro ng sidewinds when you are driving
fast erthan 50 mph (80 km/h).
If th eve hicle deviates from the direction desired
by the driver, ESP
®can stabilize theve hicle by
inter vening in thefo llowing ways:
ROne or more wheels are braked.
RThe engine output is adap ted according to
th e situation.
ESP

lamp flashes in the instrument clus ter:
RDo not deacti vate ESP®.
ROnly depress the accelera tor pedal as far as
is necessar y.
RAdapt your drivin gst yle to suit the cur rent
ro ad and weather conditions.
Deactivate ESP

RWhen using snow chains
RIn deep snow
ROn sand or gr avel.
% Spinning the wheels results in a cutting
action which pr ovides better grip.

ETS/4ETS (Electronic Traction Sy stem)
ETS/4ETS traction control is pa rtof ESP
®and
makes it possible topull away or accelerate on a
slippery sur face.
ETS/4ETS can impr oveth eve hicle's traction by
inter vening in thefo llowing ways:
RThe drive wheels are braked individually if
they spin.
RMore drive torque is transferred tothe wheel
or wheels with traction.
