R During braking, e.g. at full brake application
or insuf ficient tyre traction, the wheels are
pr ev ented from locking.
R Vehicle steerability while braking is ensured. Driving and parking

If ABS inter
venes when braking, you will 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

ph ysical limits:
R When pulling away on wet or slippe rycar ria‐

R When braking.
If th eve hicle deviates from the direction desired
by the driver, ESP ®
can stabilise theve hicle by
inter vening in thefo llowing ways:
R One or more wheels are braked.
R The engine output is adap ted according to
th e situation. When ESP

is deactivated, theå warning
lamp lights up continuously:
R Driving stability will no lon ger be impr oved.
R The drive wheels could spin.
R ETS/4ETS traction control is still active.

R Do not deactivate ESP ®
.
R Only depress the accelerator pedal as far as
is necessary when pulling away.

ETS/4ETS can impr ovetheve hicle's traction by
inter vening in thefo llowing ways:
R The drive wheels are braked individually if
th ey spin.
R More drive torque is transferred tothe wheel
or wheels with traction.
Influence of drive prog rams on ESP ®
The drive prog rams enable ESP ®
to adapt todif‐

WARNING Risk of accident in poor road
and weather conditions
In poor road and weather conditions, the
trailer stabilisation cannot pr event lur ching of

R Intheeve nt of se vere swerving, the engine
output is also reduced and all wheels are
braked.
