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

! Never tow the vehicle with one axle raised.
This may damage the transfer case. Damage
of this sort is not covered by the Mercedes-
Benz implied warranty. All wheels must
remain either on the ground or be fully raised.
Observe the instructions for towing the vehi-
cle with all wheels in full contact with the
ground.
! When testin
gthe parking brake, operate the
vehicle only briefly (for amaximum of ten sec-
onds) on abrake test dynamometer. When
doing this, turn the key to position 0or 1in
the ignition. Failure to do this can cause dam- age to the drive train or the brake system.
! Af

If you have atrailer tow hitch retrofitted,
observe the anchorage points on the chassis.
Retrofitting atrailer tow hitch is only permissible
if at railer loadiss pecified in yourv ehicledocu-

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
