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 temperature set.
If your vehicle is equipped with a hot-water
auxiliary 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 of the auxiliary
heating supports the climate control system
when the engine is runnin gand the outside
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.
i If the interior motion sensor (Y page 61)
is armed and the auxiliary heating is
switched on, it is possible that the interior
temperature monitoring may cause a false
alarm. In this case, either deactivate the
interior motion sensor or switch off the
auxiliary heating. Before switching on
X Check the fuel level and top up if necessary.
The auxiliary heating is operated directly
using the vehicle's fuel. The tan kmust be
at least a quarter full to ensure that the
auxiliary heating functions.

119Climate control Z
Problem Possible causes/consequences and
0004 Solutions
The auxiliary heating
switches off
automatically and/or
cannot be switched on. The low-voltage protection system integrated in the control unit
switches off the auxiliary heating because the on-board voltage is
less than 10 V.
X Have the alternator and battery checked. The auxiliary heating
switches off
automatically and/or
cannot be switched on. The fuse is blown.
X
Replace the fuse; see the "Fuse allocation" supplement.
X Have the cause of the blown fuse determined at a qualified
specialist workshop. The auxiliary heating
switches off
automatically and/or
cannot be switched on. A malfunction has occurred.
X
Switch the ignition on and off twice.
If the auxiliary heating still cannot be switched on, the heating
device is faulty.
X Have the auxiliary heating checked at a qualified specialist
workshop. The auxiliary heating is
overheated. The coolant level is too low.
X
Check the coolant level and add more coolant if necessary
(Y page 244). Operating the cargo compartment air
vents

WARNING
If you leave children unsupervised in the
vehicle, they could set it in motion by, for
example:
R releasing the parking brake
R shifting the automatic transmission out of
the parking position P
R starting the engine.
They could also operate the vehicle's
equipment. There is a risk of an accident and
injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle. G
WARNING
If you must brake the vehicle with the parking
brake, the braking distance is considerably
longer and the wheels could lock. There is an
increased danger of skidding and accidents.
Only use the parking brake to brake the
vehicle when the service brake is faulty. Do
not apply the parking brake too firmly. If the
wheels lock, release the parking brake until
the wheels begin turning again. The brake lamps are not illuminated when you
brake the vehicle using the parking brake.
As a rule, you may only apply the parking
brake when the vehicle is stationary. X
To apply the parking brake: pull brake
lever 0005up as far as the last possible
detent.
The 000B warning lamp in the instrument
cluster lights up if the engine is running.
i On vehicles with a folding brake lever, you
can then press lever 0005down to the stop.
X To release the parking brake: on vehicles
with a folding brake lever, first pull brake
lever 0005up to the stop.
X Raise brake lever 0005slightly and press
release knob 0006.
X Guide brake lever 0005down to the stop.
The 000B indicator lamp in the instrument
cluster goes out.
Exceptionally, if the service brake fails, the
parking brake can be used to brake the
vehicle in an emergency.
X Emergency braking: press and hold
release button 0006and carefully apply brake
lever 0005. Switching off the engine
G
WARNING
The automatic transmission switches to
neutral 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
vehicle 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.
X Stop the vehicle.
X Shift the automatic transmission to
position P. 146

Observe the following when towing a trailer:
R
Practice 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.
R Before 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
R Adjust the exterior mirrors to provide an
unobstructed view of the rear sectio nofthe
trailer.
R If 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.
R Secure the load on the trailer according to
the applicable specifications and current
standards on securing loads
(Y page 234).
R When driving with a trailer, check at regular
intervals that the load is secured and that
the brakes and lights are working.
R Bear in mind that the handling will be less
stable when towing a trailer than when
driving without one. Avoid sudden steering
movements.
R The 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. R
If possible, do not brake suddenly, but
rather moderately at first so that the trailer
can activate its brakes. Then increase the
force on the brake pedal.
R If the automatic transmission repeatedly
shifts between gears when driving on
inclines, restrict the shift range. Select shift
range 4,3,2or 1.
Driving in a low gear and at a low speed
reduces the risk of damaging the engine.
R When 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
installed, the trailer brakes.
R If the coolant temperature increases
dramatically 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.
R When overtaking, pay particular attention
to the extended length of your vehicle/
trailer combination.
Due to the length of your vehicle/trailer
combination you need an additional
distance before you can return to your
original lane. Uncoupling
atrailer G
WARNING
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 overru nbrake
is engaged.
! Do not disconnect a trailer with an
engaged overru nbrake. Otherwise, your 172
