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.
% When ESP ®
is deactivated, you are still assis‐
te dby ESP ®
when braking.
When the÷ warning lamp flashes, one or
se veral wheels has reached its grip limit:
R Adapt your driving style to suit the cur rent
ro ad and weather conditions.
R Do not deactivate ESP ®
.
R Only depress the accelerator pedal as far as
is necessary when pulling away. Deactivate ESP
®
in thefo llowing situations to
impr ovetraction:
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.
If th e÷ ESP®
wa rning lamp lights up continu‐
ousl y,ESP ®
is not available due toa malfunction.
Obse rveth efo llowing information:
R Warning and indicator lamps (/ page 487)
R Display messages (/ page 433)
ETS/4ETS (Electronic Traction Sy stem)
ETS/4E TStraction control is pa rtof ESP ®
and
makes it possible topull away and accelerate on
a slippe rycar riag ew ay.
ETS/4ETS can impr ovetheve hicle's traction by
inter vening in thefo llowing ways:
R The drive wheels are braked individually if
they 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‐
fe re nt we ather and road conditions as well as
th e driver's prefer red driving style. Depending on
th e selected drive program, the appropriate
ESP ®
mode will be activated. You can select the
drive programs using theDY NA MIC SELECT
switch (/ page156). Fu
nction of ESP ®
Crosswind Assist ESP
®
Crosswind Assist de tects sudden gu sts of
side wind and helps the driver tokeep theve hi‐
cle in the lane:
R ESP ®
Crosswind Assist is active at vehicle
speeds between appr ox.75 km/h and
200 km/h when driving stra ight ahead or
cornering slight ly.
R The vehicle is stabilised bymeans of individ‐
ual brake application on one side. 17 8
Driving and pa rking

Only use
Active Parking Assist on le vel, high- grip
ground.
Do not use Active Parking Assist in thefo llowing
situations:
R Inextreme weather conditions such as ice,
pac ked snow or in heavy rain.
R When transporting a load that pr otru des
be yond theve hicle.
R Onsteep uphill or downhill gradients of more
th an appr oximately 15%.
R When snow chains are fitted.
R When a trailer or bicycle rack is attached.
R Direct lyafte r a tyre change or when spare
tyres are fitted.
R Ifth e tyre pressure is too low or too high.
R Ifth e suspension is out of alignment, e.g.
af te r bottoming out on a kerb.
Ac tive Parking Assist may also display parking
spaces that are not suitable for parking, such as:
R Parking spaces where parking is prohibited.
R Parking spaces on unsuitable sur faces. Park

Driving and parking

Note
s on noise or unusual handling charac‐
te rist ics
Make sure there are no vibrations, noises or
unusual handling characteristics when theve hi‐
cle is in motion. This may indicate that the
wheels or tyres are damaged. Hidden tyre dam‐
age could also be causing the unusual handling
ch aracteristics.
If yo u suspect that a tyre is defective, reduce
yo ur speed immediately and ha vethe tyres and
wheels checked at a qualified specialist work‐
shop. Note
s onregular lyinspecting wheels and
tyres &
WARNING Risk of inju rydue todamaged
tyres
Damaged tyres can cause tyre pressure loss. #
Check the tyres regularly for signs of
dama geand replace any damaged tyres
immediatel y. &
WARNING Risk of aquaplaning due to
insuf ficient tyre tread
Insu fficient tyre tread will result in reduced
tyre grip.
The risk of aquaplaning is increased on wet
ro ads, especially when the speed of theve hi‐
cle is not adap tedto suit the conditions. #
Thus, you should regularly check the
tread de pth and the condition of the
tread across the entire width of all
tyres.
Minimum tread dep thfor:
R Summer tyres: 3 mm
R M+S tyres: 4 mm #
For saf etyre asons, replace the tyres
before the legally-prescribed limit for
th e minimum tread dep thisreached. Car
ryout thefo llowing checks on all wheels reg‐
ularly, at least once a month or as requ ired, for
ex ample, prior toa long journey or driving off-
ro ad:
R Check the tyre pressure (/ page 400).
R Visually inspect wheels and tyres for dam‐
age.
R Check theva lve caps.
R Visual check of the tyre tread dep thand the
tyre contact su rface across the entire width.
The minimum tread dep thfor summer tyres
is 3 mm and for winter tyres 4 mm. Note
s on snow chains &
WARNING Risk of accident due toincor‐
re ct snow chain fitting
If yo u ha vefitted snow chains tothe front
wheels, the snow chains may drag against
th eve hicle body or chassis components.
This could cause damage totheve hicle or

R Vehicles with le vel control: if snowchains
are fitted, only drive at raised vehicle le vel
( / page 209).
% You can permanently limit the maximum
