The air vents can only be adjusted on vehicles
with rear-compartment air conditioning.
Vehicles with rear-compartment air condition-
ing: in heating mode, the air in the rear com-
partment is automatically distributed in the foot-
wells and roof area after the coolant has
reached the required temperature. In cooling
mode, in the initial phase the air is distributed in
the footwells and roof area of the hot vehicle,
and subsequently only in the roof area.
XTo open: turn thumbwheel :of the rear air
vent to the center position.
XTo close: turn thumbwheel :to the upper or
lower end position.

Switching off the engine
Important safety notes
GWARNING
The automatic transmission switches to neu-
tral position Nwhen you switch off the engine.
The vehicle may roll away. There is a risk of an
accident.
After switching off the engine, always switch
to parking position P. Prevent the parked vehi-
cle from rolling away by applying the parking
brake.
!If the coolant temperature is very high, e.g.
after driving on hilly roads, leave the engine
running at idle speed for about two minutes
before turning it off.
This allows the coolant temperature to return
to normal.
Vehicles with automatic transmission
XStop the vehicle.
XShift the transmission to position P.
XApply the parking brake.
XTurn the key to position0in the ignition lock
and remove it.
The immobilizer is activated.
If you switch the engine off with the trans-
mission in position Ror D, the automatic
transmission shifts to Nautomatically.
If you then open one of the front doors or
remove the key from the ignition, the auto-
matic transmission automatically shifts to P.
If you shift the automatic transmission to N
before switching off the engine, the automatic
transmission remains in Neven if a front door
is opened.
XSecure the vehicle to prevent it from rolling
away (Ypage 133).
Parking the vehicle for a long period
If you leave the vehicle parked for longer than
four weeks, the battery may be damaged by
exhaustive discharging.
XDisconnect the battery (Ypage 259).
or
XConnect the battery to a trickle charger.
Be sure to observe the notes on charging the batteries (
Ypage 262).
You can obtain information about trickle
chargers from a qualified specialist work-
shop.
If you leave the vehicle parked for longer than 6
weeks, the vehicle may suffer damage as a
result of lack of use.
XVisit a qualified specialist workshop and seek
advice.
Driving tips
General notes
Important safety notes
GWARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.
GWARNING
If you operate mobile communication equip-
ment while driving, you will be distracted from traffic conditions. You could also lose control
of the vehicle. There is a risk of an accident.
Only operate this equipment when the vehicle
is stationary.
Observe the legal requirements of the country in
which you are driving. Some jurisdictions pro-
hibit the driver from using a mobile phone while driving a vehicle.

Driving and parking

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.
