DANG ER Risk of fata l injury due topoi‐
sonous exhaust gases
If th eta ilpipe is bloc ked or suf ficient ventila‐
tion is not possible, poisonous exhaust gases
such as carbon monoxide may enter theve hi‐
cle. This is the case in enclosed spaces or if
th eve hicle gets stuck in sn ow,fo rex ample. #
Alw ays switch thest ationary heater off
in enclosed spaces without an air
ex traction sy stems, e.g. in garage s. #
Keep theta ilpipe and the area around
th eve hicle free from snow when the
engine or thest ationary heater are run‐
ning. #
Open a window on the windward side of
th eve hicle toensure an adequate sup‐
ply of fresh air. &
WARNING Risk offire due tohot station‐
ary heater components and exhaust
ga ses
Flammable materials such as lea ves, grass or
twigs may ignite. #
When thest ationary heater is swit ched
on, make sure that:
R hot vehicle parts do not come into
contact with flammable materials.
R theex haust gas can flow out of the
st ationary heater exhaust pipe
unhindered.
R theex haust gas does not come into
contact with flammable materials. *

WARNING Risk of accident and inju ry
due toleaving children unat tended in the
ve hicle
If ch ildren are left unat tended in theve hicle,
th ey could, in pa rticular:
R open doors, thereby endangering other
persons or road users.
R get out and be stru ck byoncoming traf‐
fi c.
R ope rate ve hicle equipment and become
trapped, forex ample.
In addition, thech ildren could also set the
ve hicle in motion by,fo rex ample:
R releasing the parking brake.
R changing the transmission position.
R starting theve hicle. #
Never lea vechildren unat tended in the
ve hicle. #
When leaving theve hicle, alw aysta ke
th eke y with you and lock theve hicle. #
Keep theve hicle key out of there ach of
ch ildren. Re
quirements:
R The key is in theve hicle and is recognised.
R The brake pedal is not dep ressed. 14 4
Driving and pa rking

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

R
On slippery roads. Accelerating can cause
th e drive wheels tolose traction and the
ve hicle could then skid.
R Ifyo u are driving when visibility is poor.
Fu nction of the limiter
The limiter restricts the speed of theve hicle. To
re duce the speed tothe set speed, the limiter
applies the brakes automaticall y.
Yo u can limit the speed as follo ws:
R Variable: for a short-term speed restriction,
e.g. in built-up areas
R Perm anen t:for a longer-term speed restric‐
tion, e.g. in winter tyre mode
Yo u can store any speed abo ve20 km/h up to
th e maximum design speed or up tothe set win‐
te r tyre limit. You can also per form settings
while theve hicle is stationary if theve hicle has
been star ted.
Obser vethe no tes on driving sy stems and your
re sponsibility; you may otherwise failto recog‐
nise dangers (/ page 175).
