WARNING
Very ho torvery cold air can flow from the air
vents. This coul dresult in burns or frostbite in
the immediate vicinity of the air vents. There
is ar isk of injury.
Make sure that all vehicl eoccupants always

lets. If necessary, redirect the airflow to
another area of the vehicl einterior. In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
R keep the air inlet betwee nthe windscree nand
the bonnet free of blockages, such as ice,
snow or leaves
R never cover the vents or ventilation grilles in

If the engine does not start despite attempt stojump-start it:
X Consult aqualified specialist workshop. The starter motor was exposed to excessively high thermal load.
X Allow the starter motor to cool down for approximately two minutes.
X Try to start the engine again.

Drive sensibly –savef uel Observe the following tips to save fuel:
X The tyre sshould always be inflated to the rec-
ommended tyre pressure.
X Remove unnecessary loads.
X Remove roof carriers when they are not nee-
ded.
X Warm up the engine at low engine speeds.
X Avoid frequent acceleration or braking.
X Have all service and maintenance work car-
ried out at the specified intervals.
Fuel consumption also increases when driving in
cold weather, in stop-start traffic, on short jour- neys and in hilly terrain. Short journeys
! Vehicles with
adiesel particle filter: if the
vehicle is mostly driven for short distances, it
is possible that malfunction smay occur dur-
ing the automatic cleaning of the diesel par-
ticle filter. This may lead to fuel collecting in
the engine oil and cause engine failure. There- fore, if you frequently drive short distances,
you should take a20minute trip on amotor-
way or rural road at least every 500km. Brakes

On steep uphill or downhill inclines or if there is
am alfunction, the transmission may also be
automatically shifted into position P. Permanent all-wheel drive
! 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
unction or performanc etest should only
be carried out on atwin-axle dynamometer.
Before you operate the vehicle on such a
dynamometer, please consult aqualified
workshop. You could otherwise damage the
drive train or the brake system.
The all-wheel drive system ensures that all four
wheels are permanently driven. The all-wheel
drive system improves vehicle traction together with ESP ®
and 4ETS if adrive wheel spins due to
insufficient grip.
Only when you use winter tyres (M+S tyres) in
wintry driving condition sand, if necessary, snow

When towing atrailer, your vehicle's handling
characteristics will be differen ttowhen driving
without atrailer and th evehicle will consume

Driving tips R
Maintain agreater distance to the vehicle in

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
