General notes
Only vehicles with dual-zone automatic climate
control have the residual heat function.
Once the engine is switched off, it is possible to
make use of the residual heat of the engine to
continue heating or ventilating the front com-
partment of the vehicle for approximately
30 minutes. The heating or ventilation time
depends on the set interior temperature.

iWe recommend that you additionally carry a
shovel and a recovery rope with shackle in the
vehicle.
REnsure that loads and items of luggage are
securely stowed or lashed down
(
Ypage 242).
RBefore driving off-road, stop the vehicle and
shift to a low gear.
RIf the surface requires, temporarily deactivate
ESP®when pulling away (Ypage 66).
ROnly drive off-road with the engine running
and a gear engaged.
RDrive slowly and smoothly. Walking pace is
necessary in many situations.
RAvoid spinning the drive wheels.
RMake sure that the wheels always remain in
contact with the ground.
RDrive with extreme care over unknown terrain
where you can only see for a short distance.
As a precaution, get out of the vehicle to take
a look at the route to be taken in advance.
RCheck the water depth before fording.
RWatch out for obstacles (e.g. rocks, holes,
tree stumps and ruts).
RAvoid edges where the surface could crumble
or break away.
Checklist after driving off-road
!If you detect damage to the vehicle after
driving off-road, have the vehicle checked
immediately at a qualified specialist work-
shop.
Off-road driving places a higher demand on your
vehicle than normal road operation. Check your
vehicle after driving on rough terrain. By doing
so you will notice any damage in good time and
reduce the risk of an accident for yourself and
other road users. Clean your vehicle thoroughly
before driving on public roads.
Observe the following points after driving off-
road, on construction sites and before driving on
public roads:
XActivate ESP®(Ypage 66).
XClean the headlamps and tail lamps and
check them for damage.
XClean the front and rear license plates.
XClean the windshield, windows and exterior
mirrors.
XClean the steps, door sills and grab handles.
This increases safety of footing.
XClean the wheels/tires, wheel housings and
the underbody of the vehicle with a water jet. This increases road grip, especially on wet
road surfaces.
XCheck the wheels/tires and wheel housings
for trapped foreign objects and remove them.
Trapped foreign objects can damage the
wheels/tires and may be flung out from the
vehicle when you continue driving.
XCheck the underbody for trapped branches or
other parts of plants and remove them.
Trapped branches or other parts of plants
increase the risk of fire and can cause dam-
age to fuel lines, brake hoses and the rubber
bellows of axle joints and drive shafts.
XClean the brake disks, brake pads and axle
joints, particularly after operation in sand,
mud, grit/gravel, water or similarly dirty con-
ditions.
XCheck the entire floor assembly, the tires,
wheels, bodywork structure, brakes, steering,
chassis and exhaust system for any damage.
XCheck the service brake for operating safety,
e.g. carry out a brake test.
XIf you notice strong vibrations after driving off-
road, check the wheels and drive train for for- eign objects again. Remove any foreign
objects which can lead to imbalances and
thus cause vibrations.
Driving in mountainous areas
When driving in mountainous areas, note that
the power output of the engine, and with it its
gradient climbing capability, decrease with
increasing altitude. Please take note of this par-
ticularly when driving with a trailer in mountain-ous areas.
The maximum permissible trailer loads are valid
for journeys at altitudes up to 1100 yds
(1000 m) above sea level with gradients up to
12%.
Information on maximum permissible trailer
loads can be found in your vehicle registration
papers and on the vehicle identification plate
(
Ypage 303) or under "Trailer loads"
(Ypage 314).

tened to the vehicle's trailer coupling, not to
the bumper or the axle.
Leave enough slack in the chains. This allows
you to drive round tight corners.
Ra separate brake system for certain types of
trailer.
Ra safety shut-off for braked trailers. Find out
the specific requirements according to the
applicable laws.
If the trailer becomes detached from the tow-
ing vehicle, the safety shut-off applies the
trailer brakes.
Towing a trailer
There are numerous legal requirements con-
cerning the towing of a trailer, e.g. speed restric-
tions. Many states require a separate functional
braking system for your trailer once a certain
weight limit is exceeded. For reasons of safety,
it is recommended that all trailers use a sepa-
rate functional braking system. Make sure yourvehicle/trailer combination complies with local
laws. This not only means where you live, but
also anywhere you are driving to. Information on
this can be obtained from the police and local
authorities.
Observe the following when towing a trailer:
RPractice driving around bends, stopping and
backing up at a place where there is no traffic.
This enables you to gain experience and get
used to the new handling characteristics.
RBefore driving, check:
-that the trailer tow hitch and ball coupling
are secure
-that the safety switch for a braked trailer is
functioning properly
-that the safety chains are secure and not
damaged
-that the electrical connections are secure
-that the lights are working
-that the wheels are in good order and the
tire pressure is correct
RAdjust the exterior mirrors to provide an
unobstructed view of the rear section of the
trailer.
RIf the trailer is equipped with a separate func-
tional braking system, check before each
journey whether the brakes are functioning
correctly.
RSecure the load on the trailer according to the
applicable specifications and current stand-
ards on securing loads (
Ypage 244).
RWhen driving with a trailer, check at regular
intervals that the load is secured and that the
brakes and lights are working.
RBear in mind that the handling will be less
stable when towing a trailer than when driving
without one. Avoid sudden steering move-
ments.
RThe vehicle/trailer combination is heavier,
accelerates more slowly and has a decreased
gradient climbing capability and a longer
braking distance.
It is more susceptible to crosswinds and
requires cautious steering.
RIf possible, do not brake suddenly, but rather
moderately at first so that the trailer can acti-
vate its brakes. Then increase the force on the
brake pedal.
RIf the automatic transmission repeatedly
shifts between gears when driving on inclines,
restrict the shift range. Select shift range
4,3 ,
2 o
r 1.
Driving in a low gear and at a low speed
reduces the risk of damaging the engine.
RWhen driving on a downhill gradient, shift to a
low gear and take advantage of the engine's
braking effect.
Avoid continuous brake application as this
may overheat the vehicle brakes and, if instal-
led, the trailer brakes.
RIf the coolant temperature increases dramat-
ically while the air-conditioning system is
switched on, switch off the air-conditioning
system.
Coolant heat can also be dissipated by
switching the airflow and the temperature of
the air conditioning to the maximum level.
Open the windows if necessary.
RWhen overtaking, pay particular attention to
the extended length of your vehicle/trailer
combination.
Due to the length of your vehicle/trailer com- bination you need an additional distance
before you can return to your original lane.
