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

R When braking.
R Vehicles with trailer hitch: in trailer opera‐

R Instro ng side winds when you are driving
fa ster than 80 km/h.
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.
ESP ®
is deactivated if theå ESP®
OFF warn‐

clus ter. Obser
vethefo llowing points when ESP ®

tivated:
R Driving stability will no lon ger be impr oved.
R Vehicles with trailer hitch: stabilisation of
th eve hicle/trailer combination is no longer
active.
R Crosswind Assist is no longer active.
R The drive wheels could spin.
R ETS/4ETS traction control is still active.

R Onlydepress the accelerator pedal as far as
is necessar y. It may be best
todeactivate ESP ®
in thefo llow‐
ing situations:
R When using snow chains.
R In deep sn ow.
R On sand or gr avel.
% Spinning the wheels results in a cutting
action, which enhances traction.
