WARNING
If you select the LOW RANGE off-road gearon as lippery road surface, the wheels coul dlose
traction:
R if you release the accelerator peda lwhen
the vehicl eisinmotion
R if Off-road ABS intervenes when braking
If the wheels lose traction, it willnol onger be
possible to steer the vehicle. This increases
the risk of skidding and having an accident.
Never select the LOW RANGE off-road gear
when driving on slippery road surfaces.

less braking will be required to maintai nthe
vehicl espeed. Thi srelieves the load on the
brake system and prevents the brakes from
overheating and wearing too quickly.
Heav yand light loads G
WARNING
The braking system can overheat if you leave you rfoot on the brake peda lwhile driving.
This increases the braking distance and could
even caus ethe braking system to fail .There is
ar isk of an accident.
Never use the brake peda lasafootrest. Do
not simultaneously depress both the brake
peda land the accelerator peda lwhile driving.
! Depressing the brake peda
lconstantly
results in excessive and premature wearto
the brake pads.
If heavy demands are made on the brakes ,do
not park the vehicl eimmediately. Drive on for a
short while. This allows the airflow to cool the
brakes more quickly.
If the brakes have been used only moderately,
you should occasionall ytest their effectiveness.
To do this, brake more firmly from ahigher speed while paying attention to the traffic con-
ditions .This improves the grip of the brakes.
Wet road surfaces If driving in heavy rain for
aprolonge dperiod of
time withou tbraking, there may be adelayed
reaction from the brakes when braking for the
first time. This may also occur after the vehicle
has been washed.
You have to depres sthe brake pedalm ore
firmly .Maintai nagreater distance from the
vehicle in front.
After driving on awet road or having the vehicle
washed, brake firmly whilep aying attention to
the traffic conditions. This willw arm up the
brake discs, thereby drying them more quickly
and protecting them against corrosion.
Limited braking performance on salt-
treated roads If you drive on salt-treated roads,
alayer of salt
may form on the brake discs and pads.T his can
increase the braking distance considerably.
R In order to prevent any salt build-up,a pplythe
brakes occasionally whilep aying attention to
the traffic conditions.
R Carefullyd epressthe brake pedalatt he end
of the journey and when starting the next
journey.
R Maintai namuch greater distance to the vehi-
cle in front.
New brake discs and brake pads/
linings Brake pads/linings and discs that either are new
or have been replaced achieve optimum braking
effect only after several hundred kilometres of
driving. Compensate for the reduced braking
effect by applying greater force to the brake
pedal.
For safety reasons, Mercedes-Benz recom-
mends only fittingt he following brake discs and
brake pads/linings:
R brake discs that hav ebeena pproved by
Mercedes-Benz
R brake pads/linings that hav ebeena pproved
by Mercedes-Benz or that are of an equivalent
standard of quality
Other brake discs or brake pads/linings can
compromise the safety of your vehicle. 116

Bear in mind that vehicles travelling in front
or in the opposite direction create waves. This may cause the maximum permissibl ewater
depth to be exceeded. These notes must be observed under all cir-
cumstances. You could otherwise damage
the engine, the electronics or the transmis-
sion.
If you must drive on stretches of road on which
water has collected, please bear in mind that:
R in the case of standing water, the water level
must be no higher than the lower edge of the

WARNING
Flammable materia lsuch as leaves, grass or
twigs may ignite if they come into contact with hot parts of the exhaust system. There is arisk
of fire.
When driving off road or on unpaved roads,
check the vehicle's underside regularly. In
particular, remove parts of plants or other
flammable materials which have become
trapped. In the case of damage, contact a
qualified specialist workshop.
! There is
arisk of damage to the vehicl eif:
R the vehicl ebecome sstuck, e.g. on ahigh
kerb or an unpaved road
R you drive too quickly over an obstacle, e.g.
ak erb, slowing thresholds or apothol ein

R ah eavy object strikes the underbody or
parts of the chassis
In situations like this, the body ,underbody,
chassi sparts, wheels or tyres coul dbedam-
agedw ithout the damage being visible. Com-
ponents damaged in this way can unexpect-
edlyf ail or, in the case of an accident, no lon-
ger withstand the strain they are designed to withstand.
If the underbody panelling is damaged, com-
bustible materials such as leaves, grass or
twigs can gather between the underbody and
the underbody panelling. If these materials
come into contact with hot parts of the
exhaust system, they can catch fire.
In such situations, have the vehicl echecked
and repaired immediatel yataqualified spe-
cialist workshop. If, on continuing yourj our-
ney, you notice that driving safety is impaired, stop the vehicle immediately
,paying atten-
tion to road and traffic conditions. In such
cases, consult aqualified specialist work-
shop.
! If there are steep gradients while driving off-
road, asufficient filling level in the AdBlue ®
tank must be ensured. Make sure for this rea- son that there is aminimum fill level of ten
litres before driving off-road.
When driving off-road, substances such as sand,
mud and water or water mixed with oil may get
into the brakes. This may lead to areduction in
braking performance or total brake failure as a
result of increased wear. The braking charac-
teristics will vary depending on the substances
that get into the brakes. Cleant he brakes after
driving off-road. If you notice grinding noises or ar eduction in braking performance, have the
brake system checked at aqualified specialist
workshop immediately.A dapt your driving style
to the altered braking characteristics.
Driving off-road increases the possibility of dam- age to the vehicle, which may cause assemblies
or systems to fail. Adapt your driving style to the
conditions of the terrain. Drive carefully.H ave
vehicle damage rectified immediately at aquali-
fied specialist workshop.
Do not shift into transmission position Nwhen
driving off-road. You could lose control of the
vehicle if you attempt to brake the vehicle using
the service brake. If the gradient is too steep for your vehicle, back up in reverse gear.

To avoid hazardous situations:
R make sure to check the noseweight before
each journey
R the noseweight should be as close as possible
to the maximum noseweight
R do not exceed the maximum permissible
noseweight
R the noseweight must not be lower than the
minimum permissible noseweight
Make sure that the following values are not
exceeded:
R the permissible noseweight
R the permissible trailer load
R the permissible rear axle load of the towing
vehicle
R the maximum permissible gross vehicle
weight of both the towing vehicle and the
trailer
When reversin gthe towing vehicle, make sure
there is nobody between the trailer and the vehi- cle.
The applicable permissible values, which must
not be exceeded, can be found:
R in your vehicle documents
R on the type plates for the trailer
R on the vehicle identification plate
If the values differ, the lowest value applies.
You will find the values approved by the manu-
facturer on the identification plates and for the
towing vehicle under "Technical data"
(Y page 256).
When reversin gthe towing vehicle, make sure
there is nobody between the trailer and the vehi- cle.
Couple and uncouple the trailer carefully. If youdo not couple the trailer to the towing vehicle
correctly, the trailer could become detached.
When towing atrailer, your vehicle's handling
characteristics will be different from when driv-
ing without atrailer.
The vehicle/trailer combination:
R is heavier
R is restricted in its acceleration and gradient-
climbing capability
R has an increased braking distance
R is affected more by stron gcrosswinds
R demands more sensitiv esteering
R has alarger turnin gcircle This can impair the vehicle's handling charac-
teristics. Adapt your driving style accordingly.
Maintain asafe distance. Drive carefully.
When towing atrailer, alway sadjust your speed
to the current road and weather conditions. Do
not exceed the maximum permissible speed for
your vehicle/trailer combination. Notes on to
wingatrailer
General notes When towing
atrailer, set the tyre pressure on
the rear axle of the towing vehicle for amaxi-
mum load. Further information on the tyre pres-
sure table in the fuel filler flap (Y page 109).
The height of the ball coupling changes with the load of the vehicle. If necessary, use atrailer
with aheight-adjustable drawbar.
You will find permissible trailer loads under
"Technical data" (Y page 256).
Driving tips X
Observe the information on ESP ®
trailer sta-
bilisation (Y page 55).
X On long and steep downhill gradients, select
shift range 1,2or 3(Y page 105) in good time.
X If necessary, shift the transfer case to LOW
RANGE (Ypage 124).
This will use the braking effect of the engine, so less braking will be required to maintain
the vehicle speed. This relieves the load on
the brake system and prevents the brakes
from overheating and wearing too quickly. If
you need additional braking, depress the
brake pedal repeatedly rather than continu-
ously.
The maximum permissible speed for vehicle/
trailer combinations depends on the type of
trailer. Before beginnin gthe journey, check the
trailer's documents to see what the maximum
permitted speed is. Observe the maximum per-
missible speed in the relevant country.
For certain Mercedes-Benz vehicles, the maxi-
mum permissibler ear axle load is increased
when towing atrailer. See the "Technical data"
section to find out whether this applies to your
vehicle (Y page 256). In the event of increased
rear axle load, the car/trailer combination may
not exceed amaximum speed of 100 km/h for
reasons concerning the operating permit. This 128
Towing
atrailerDriving and parking

also applies in countries in whic
hthe maximum
permissible spee dfor car/trailer combinations
is greate rtha n1 00 km/h.
When towing atrailer, your vehicle's handling
characteristics will be differen ttowhen driving
without atrailer and th evehicle will consume
mor efuel.
Driving tips R
Maintain agreater distance to the vehicle in
front than when driving without atrailer.
R Avoid braking abruptly. If possible, brake gen-
tly at first to allow the trailer to run on. Then,
increase the braking force rapidly.
R The values given for gradient-climbing capa-
bilities from astandstill refer to sea level.
When driving in mountainous areas, note that
the power output of the engine, and conse-
quently the vehicle's gradient-climbing capa-
bility from astandstill, decrease with increas-
ing altitude.
If the trailer swings from side to side:
X Do not accelerate under any circumstances.
X Do not countersteer.
X Brake, if necessary. Coupling up
atrailer
! Do no
tconnect th etrailer brak esystem (if
th et railer is fitte dwitho ne)d irectly to the
towing vehicle's hydraulic brak esystem,
since this is equipped wit hananti-lock brak-
ing system. Otherwise, neither th ebrakes on
th et ow ing vehicle no rthe brakes on the
trailer will work.
Observ ethe maximum permissible trailer
dimension s(widt hand length).
X Apply th evehicle's parking brake.
X Mak esure that th eautomatic transmission is
in transmission position P.
X Positio nthe trailer on aleve lsurface behind
th ev ehicle.
X Couple up th etrailer.
X Establish th eelectrical connection between
th ev ehicle and th etrailer.
X Chec kthatthe trailer lighting system is work-
ing.
X Push th ecombinatio nswitch upward sand
downwards and check whether th ecorre- sponding tur
nsignal indicator on the trailer is
flashing.
Ac onnected trailer is only detected when the
electrical connection is established correctly
and when the lighting system is working prop-
erly. The function of other systems, such as
ESP ®
also depends on this. Uncoupling

WARNING
If you uncouple atrailer with an engaged over-
run brake, you coul dtrap yourh and between
the vehicl eand the trailer drawbar. This poses
ar isk of injury.
Do not uncouple atrailer with an engaged
overru nbrake.
! Do not disconnect

WARNING
Interchangin gthe front and rear wheels may
severely impair the driving characteristics if
the wheels or tyres have different dimensions. The whee lbrakes or suspension components
may alsobed amaged. There is arisk of acci-
dent.
Interchange front and rear wheels only if the
wheels and tyres are of the same dimensions.
! On vehicles fitted with
atyre pressure mon-
itor, electronic components are located in the wheel.
Tyre-fitting tools should not be appliedint he
area of the valve ,asthis coul ddamage the
electronic components.
Only have tyres changed at aqualified spe-
cialist workshop.
Interchanging front and rear wheels of differing
dimensions can render the genera loperating
permi tinvalid.
Always pay attention to the instructions and
safety notes under "Changing awheel"
(Y page2 43). The wear patterns on the front and rear tyres
diffe
rdepending on the operating conditions.
Interchange the wheels before aclear wear pat-
tern has formed on the tyres. Frontt yres typi-
cally wear more on the shoulders, while rear
tyres wear more in the centre.
On vehicles that have front and rear wheels of
the same size, you can interchange the wheels
every 5,000 to 10,00 0kmd epending on the
degree of tyre wear. Ensure that the direction of
rotation is maintained.
Clean the contact surfaces of the wheel and the
brake disc thoroughly every time awheel is
interchanged. Check the tyre pressure and reac-
tivate the tyre pressure monitor if necessary
(Y page 241). Direction of rotation
Tyres with aspecifie ddirection of rotation have
additional benefits, e.g. if there is ariskofa qua-
planing. You will only gain these benefit sifthe
correc tdirection of rotation is observed.
