WARNING Risk of accident when switch‐
ing off the ignition when driving
If yo u swit choff the ignition while driving,
saf ety functions are restricted or no longer
av ailable. This may af fect the po werst eering
sy stem and the brake forc e boosting, for
ex ample.
Yo u will then need touse considerably more
fo rc eto steer and brake. #
Do not switch off the ignition while driv‐
ing. &
DANG ER Risk of fata l injuries due to
ex haust gases
Combustion engines emit poisonous exhaust
ga ses such as carbon monoxide. Inhaling
th ese exhaust gases is hazardous tohealth
and can lead topoisoning. #
Never lea vethe engine running in an
enclosed space wi thout suf ficient venti‐
lation. &
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 if theve hicle getsst uck
in sn ow,fo rex ample. #
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 of accident and inju ry
due tobeing under the influence of alco‐
hol and drugs while driving
Driving when under the influence of alcohol
and/or drugs is an extreme lydangerous com‐
bination. Even small quantities of alcohol or
drugs may af fect your reflexe s, perception
and judgment.
The probability of a serious or evenfa ta l acci‐
dent greatly inc reases if you drive when
under the influence of alcohol or drugs. #
Do not drink alcohol or take drugs while
driving, and do not allow an yone todrive who has been drinking alcohol or
taking
drugs. &
WARNING Risk of accident and injury
from ope rating mobile communications
equipment
If yo u operate mobile communication equip‐
ment when driving, you will be distracted
from the traf fic situation. This could also
cause youto lose control of theve hicle.
The probability of a serious or evenfa ta l acci‐
dent inc reases greatly if you operate mobile
communication equipment when driving. #
Only operate mobile communication
equipment when theve hicle is station‐
ar y. Fo
ryo ur ow n sa fety, al ways obser vethefo llowing
points when operating mobile communications
equipmen t:
R Obser vethe legal requ irements forth e coun‐
try in which you are driving.
R While driving, on lyoperate mobile communi‐
cations equipment when the tra ffic conditions
permit it. You may otherwise be distracted
from the traf fic conditions and cause an acci‐
dent, inju ring yourself and others. &
WARNING Risk of accident due toove r‐
heated brake sy stem
If yo ure st your foot on the brake pedal during
while driving, the brake sy stem may overheat.
This increases the braking dis tance and the
brake sy stem may evenfa il. #
Never use the brake pedal as a foot re st. #
Do not press the brake pedal and accel‐
erator pedal simultaneously while driv‐
ing. On long and
steep downhill gradients, you should
ch ange down toa lo werge ar in good time. Take
particular no teofthis when driving a laden vehi‐
cle. By doing so, you will make use of the
engine's braking ef fect. This relie vesth e load on
th e brake sy stem and pr events the brakes from
ove rheating and wearing tooqu ickl y. 106

WARNING Risk of skidding and of an
accident due toshifting down on slippery

If yo u shift down on slippery road sur faces to
inc rease the engine braking ef fect, the drive
wheels may lose traction. #
Do not shift down on slippery road sur‐
fa ces toinc rease the engine braking
ef fect. Ve
hicles with automatic transmissions may roll in
neut ral position 005Cfor only a short time. Allowing
th e wheels torollfo r longer, e.g. when towing,
causes transmission damage.
If th eve hicle thre atens toskid, or cannot be stop‐

lize theve hicle using thefo llowing measures:
R Shift the automatic transmission toneutral
position 005C.
R Tryto maintain control of theve hicle using
cor rective steering.
Drive particularly carefully on slippery roads.
Av oid sudden acceleration, steering and braking
maneuver.
Ha ve your vehicle winterized at a qualified spe‐
cialist workshop in good time at the onset of win‐
te r.
Obser vethe instructions in the section "No tes on
snow chains" (/ page 233).
Re gular lych eck theve hicle and remo vesnow or
ice when tr aveling in wintry conditions. An accumulation of snow and ice, particular
ly
when frozen, in the area around the air intake,
moving parts, the axles and the wheel housing,
may cause thefo llowing problems:
R Obstruction of the air intake
R Damage tovehicle parts
R Malfunctions due torestriction of mobility
intended bythe design (e.g. reduced steering
mo vement)
If th ere is any damage, inform a qualified special‐
ist workshop.

Ifth e trailer has electronically cont rolled
brakes, pull away carefully wi th theve hicle/
trailer combination. Brake manually using the
brake controller and check whe ther the
brakes are functioning cor rectly.
R Secu rethe load on the trailer in line with the
re qu irements and rules for load-securing
me thods.
R When driving with a trailer, check at regular
inter vals that the load is secure and that the
lights and brakes are functioning cor rectl y.
R Bear in mind that the handling characteristics
are more uns table when towing a trailer than
when driving without a trailer. Avoid sudden
st eering mo vements.
R The vehicle/trailer combination is heavier,
accelerates more slowl y,has a reduced
climbing ability and an increased braking dis‐
ta nce. It is more susceptible toside winds
and requ ires careful steering.
R If possible, do not brake suddenl y,but rath er
moderately at firs t so that the trailer can acti‐
va te its brakes. Then inc rease the pressure on
th e brake pedal.
R Ifth e automatic transmission shifts between
ge ars on uphill or downhill gradients, restrict
th e shift range. Select shi ftrange 4, 3, 2 or 1.
A lo werge ar and reduced speed decrease the
ri sk of engine damage.
R When driving on a downhill gradient, shift to a
lo we rge ar to use the engine's braking ef fect.
Av oid cons tant braking, as this could cause
th eve hicle brakes and possibly also the

R Ifth e coolant temp erature increases signifi‐

te m off.
Coolant heat can also be dissipated by
switching the air flow and thete mp erature of
