GWARNING
When the auxiliary heating is switched on,
parts of the vehicle can become very hot, e.g.
the exhaust system.
Flammable materials such as leaves, grass or
twigs may ignite if they come into contact
with:
Rhot parts of the exhaust system
Rthe exhaust gas itself
There is a risk of fire.
When the auxiliary heating is switched on,
make sure that:
Rno flammable materials come into contact
with hot vehicle components
Rthe exhaust gas can escape from the
exhaust pipe unhindered
Rthe exhaust gas does not come into contact
with flammable materials.
!Turn on the auxiliary heating at least once a
month for approximately 10 minutes. The
auxiliary heating could otherwise be dam-
aged.
!Make sure that the flow of hot air is not
blocked. The auxiliary heating will otherwise
overheat and switch off.
Your vehicle may be equipped with either an
auxiliary hot-water heater or an auxiliary warm-
air heater. Adjustment and operation of the:
Rhot-water auxiliary heater is done via the on-
board computer and with the auxiliary heating
button in the control panel (
Ypage 109) or
with the remote control (Ypage 110).
Rauxiliary warm-air heater is done via the timer
above the overhead control panel
(
Ypage 114).
The auxiliary heating works independently of the
engine and supplements the climate control
system in the vehicle. The auxiliary heating
heats the air in the vehicle interior to the tem-
perature set.
If your vehicle is equipped with a hot-water aux-
iliary heater, the auxiliary heating also keeps the
coolant warm. This way, the load on the engine
is minimized and fuel is saved.
The heater booster function (
Ypage 112) of the
auxiliary heating supports the climate control system when the engine is running and the out-
side temperature is low.
You can use the auxiliary heating at an outside
temperature of up to 39 ‡ (4 †). At an outside
temperature above 39 ‡ (4 †) the auxiliary
heating system and the heater booster function
switch off automatically.
Hot-water auxiliary heating
Heating time
The heating time when operating the auxiliary
heating with the vehicle is stationary without the
engine running depends on the outside temper-
ature and the electrical consumers switched on.

Below 5‡
( Ò 15 †)Approx.
50 minutes2
You can then switch on the auxiliary heating
again.
If you do not start the engine for a while, the total
duration of heating is limited to a maximum of
120 minutes to protect the starter battery.
Switching on the auxiliary heating is then auto-
matically disabled. You can, for example, switch
on the auxiliary heating a maximum of two times
without the engine running if the outside tem-
perature is Ò5 ‡ (Ò20 †). If you attempt to do it
again, the indicator lamps in the y
(
Ypage 109) button flash alternately for about
two minutes indicating restarting lock. The aux-
iliary heating cannot be switched on without
starting the engine.
When the condition of charge of the starter bat-
tery is sufficient again, the switch-on interlock
will be deactivated. To charge the starter bat-
tery, let the engine run. The engine run time
required to reach the necessary condition of
charge depends on the outside temperature and
on the electrical consumers switched on.

Exceptionally, if the service brake fails, the park-
ing brake can be used to brake the vehicle in an
emergency.
XEmergency braking: press and hold release
button ;and carefully apply brake lever :.
Switching off the engine
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.
XStop the vehicle.
XShift the automatic transmission to position
P .
XApply the parking brake.
XTurn the key to position 0in the ignition lock
and remove it.
The immobilizer is activated.
XSecure the vehicle to prevent it from rolling
away (Ypage 129).
Wheel chock
Use the wheel chock or a similar object to pre-
vent the vehicle from rolling away, e.g. when
parking or changing a wheel.
Wheel chock in the load/passenger compartment
XTo remove the wheel chock on Cargo
Vans/Passenger Vans: pull restraining
cable :down a little and remove it from

ing to. Information is available 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 an individual
braking system, check before each journey
whether the brakes are functioning correctly.
RIf the trailer has electronically controlled
brakes, pull the vehicle/trailer combination
away carefully. Brake manually using the
brake controller and check that the brakes
are working.
RSecure the load on the trailer according to the
applicable specifications and current stand-
ards on securing loads (
Ypage 215).
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 long er
brak

ing 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 or 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 heater/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.
Uncoupling a trailer
GWARNING
If you uncouple a trailer with the overrun
brake engaged, you could trap your hand
between the vehicle and the trailer drawbar.
There is a risk of injury.
Do not uncouple a trailer if the overrun brake
is engaged.
!Do not disconnect a trailer with an engaged
overrun brake. Otherwise, your vehicle could
be damaged by the rebounding of the overrun
brake.
XMake sure the selector lever of the automatic
transmission is in position P.
XApply the parking brake of the vehicle.
XClose all doors.
XApply the parking brake of the trailer.
XIn addition, secure the trailer against rolling
away with a wheel chock or similar object.
XRemove the trailer cable and safety chains
and decouple the trailer.
