vents 1.Auxiliary heating (auxiliary heating and ventilation)*Description and important information
The auxiliary heating (auxiliary he ating and ventilation) heats or
supplies the interior of the vehicl e with fresh air independent of the
engine.Auxiliary heating (auxiliary heating)
The auxiliary heating (auxiliary heating) functions in connection with the Climatic or
Climatronic.
It can be used when stationary, when engi ne is switched off for preheating of the
vehicle as well as while driving (only during the heating phase of the engine).
The auxiliary heating (auxiliary heating) wa rms up the coolant during the combustion
of fuel from the vehicle tank. The coolant warms up the air, which (if the blower speed
is not set to zero) flows into the occupant compartment.
Auxiliary ventilation
The auxiliary ventilation enables fresh air to flow into the vehicle interior by switching
off the engine, whereby the interior temperature is effectively decreased (e.g. with the
vehicle parked in the sun).

WARNING

The auxiliary heating must never be operated in closed rooms - risk of
poisoning!

The auxiliary heating must not be runn ing during refueling - risk of fire.

The exhaust pipe of the auxiliary heating is located on the underside of the
vehicle. Therefore do not place the vehicl e, if you wish to operate the auxiliary
heating, in such a way that the exhaust gases of the auxiliary heating can come
easily into contact with inflammable mate rials (e.g. dry grass) or easily inflam-
mable substances (e.g. fuel run out).Note

If the auxiliary heating runs, the fuel consumption comes from the vehicle tank.
Therefore the auxiliary heating should not be op erated, if there is very little fuel in the
tank.

The exhaust pipe of the auxiliary heating, which is located on the underside of the
vehicle, must not be clogged and the exhaust flow must not be blocked.

If the auxiliary heating and ventilation is running, the vehicle battery discharges. If
the auxiliary heating and ventilation has be en operated several times over a longer
period, the vehicle must be driven a few ki lometers in order to recharge the vehicle
battery.

The auxiliary heating only switches the blower on, if it has achieved a coolant
temperature of approx. 50 °C.

At low outside temperatures, this can result in a formation of water vapour in the
area of the engine compartment. This is quite normal and is not an operating problem.

After switching off the auxiliary heating, the coolant pump runs for a short period.

The auxiliary heating and ventilation does not switch on or comes on, if the vehicle
battery indicates a low loading state.

The auxiliary heating (auxiliary heating) does not switch on, if the following was
shown in the information display or before switching off the ignition: Please refuel!
(Please refuel!) .

The air inlet in front of the windscreen must be free of ice, snow or leaves in order
to ensure that the auxiliary heating operates properly.

So that warm air can flow into the vehicl e interior after switching on the auxiliary
heating, you must maintain the temperature normally selected by you (we recom-
mend 22°C). It is recommended to put the air flow in the position
.

On vehicles with DPF (diesel particle filter) the warm coolant heats up the engine.
Direct switching on/offThe auxiliary heating (auxiliary heating and vent ilation) can be switched on or off at any
time directly using the button on the operating part of the Climatic fig. 109 or
on the operating part of the Climatronic.
If the auxiliary heating and ventilation is not switched off earlier, it switches off auto-
matically after the expiration of the set operating period, in the menu Running time.Using the system
So that the auxiliary heating (auxiliary heating and ventilation) func-
tions according to your expectations, it is necessary to carry out the
basic setting before its programming.Basic setting– On the information display, select from the Main menu the menu point
Aux. heating .
– In the menu Aux. heating select the menu point Weekday and set the current day.
– Return to a higher level by selecting the menu point Back, i. e. in the menu

poisonous gas - hazard! Carbon monoxide can cause unconsciousness and
death.

Never leave your vehicle unattended with the engine running.Caution

The starter may only be operated (ignitio
n key position ), if the engine is not
running. If the starter is immedi ately operated after switching off the engine, the starter
or the engine can be damaged.

Avoid high engine revolutions, full throttle and high engine loads as long as the
engine has not yet reached its normal oper ating temperature - risk of damaging the
engine!

Vehicles which are fitted with an exhaust gas catalytic converter should not be tow-
started over a distance of more than 50 metres.For the sake of the environment
Never warm up the engine when the vehicle is standing. Drive off right away. Through
this the engine reaches its operating temperature more rapidly and the pollutant emis-
sions are lower.Petrol enginesThese engines are fitted with a starter system which selects the correct fuel-air mixture
for every external air temperature.
Do not operate accelerator before and when starting engine.

Interrupt the attempt at starting after 10 seconds if the engine does not start right
awayand wait for about 30 seconds before repeating the attempt.

It is possible that the fuse on the electric al fuel pump is defect if the engine still
does not start. Check the fuse and replace it if necessary page 226.

Contact the nearest specialist garage to obtain professional assistance.
It may be necessary, if the engine is very hot, to slightly depress the accelerator after
the engine has started.
Diesel enginesGlow plug system
Diesel engines are equipped with a glow plug system, the preglow period being
controlled automatically in line with the coolant temperature and outside tempera-
ture.
The preglow indicator light
 comes on after the ignition has been switched on.
You should not switch on any major electrical components during the heating
period otherwise the vehicle battery will be drained unnecessarily.

You should start the engine immediately after the glow plug warning light
 has
gone out.

The glow plug warning light will come on for about one second if the engine is at a
normal operating temperature or if the outside temperature is above +5°C. This means
that you can start the engine right away.

Interrupt the attempt at starting after 10 seconds if the engine does not start right
awayand wait for about 30 seconds before repeating the attempt.

It is possible that the fuse on the diesel preglow system is defect if the engine still
does not start. Check the fuse and replace it if necessary page 226.

Contact the nearest specialist garage to obtain professional assistance.
Starting the engine after the fuel tank has run dry
It may take longer than normal to start the engine after refuelling if the fuel tank has
run completely dry - up to one minute. This is because the fuel system must first of all
be filled while the attempting to start the engine.
Switching off the engine– The engine can be switched off by turnin g the ignition key from position into
 page 107, fig. 111.
WARNING

Never switch off the engine before the vehicle is stationary - risk of accident!


The brake booster only operates when the engine is running. Greater phys-
ical effort for braking is required when en gine is switched off. Because if you do
not stop as normal, this can cause an accident and severe injuries.Caution
you should not switch the engine off right away at the end of your journey after the
engine has been operated for a lengthy period at high loads but should be allowed it
to run at idling speed for about 2 minutes. This prevents any accumulation of heat
when the engine is switched off.
Note

The radiator fan may continue running fo r a further 10 minutes or so after the
engine and the ignition have been switched off. The coolant fan may, however, also
switch on again after some time if the co olant temperature rises because of an accu-
mulation of heat in the engine or if the engine is warm and the engine compartment is
additionally heated by strong sunlight.

This is why particular care is required when carrying out any work in the engine
compartment  page 197, “Working in the engine compartment”.
Shifting (manual gearbox)
Shift into reverse only when the vehicle is stationary. Depress the clutch pedal and hold
it fully depressed. Wait a mo ment before engaging reverse gear in order to avoid any
shift noises.
The reversing lights will come on once reverse gear is engaged, provided the ignition is
on.
WARNING
Never engage the reverse gear when driving - risk of accident!
Note

One should not lay the hand on the shift lever while driving the vehicle. The pres-
sure of the hand will be transferred to the gearshift forks in the gearbox. This can, over
a period of time, lead to earl y wear of the gearshift forks.

Depress the clutch pedal fully when changi ng gears, in order to avoid unnecessary
wear and damage.

Technical Data
Headlights
Before starting off with a hitched trailer, also check the setting of the headlights. Alter
the setting as necessary with the ai
d of the headlight beam adjuster page 56.
Detachable ball head
The ball rod is detachable on vehicles which feature a factory-fitted towing device. It is
stowed together with separate fitting instru ctions in the spare wheel well in the luggage
compartment of the vehicle.
Further information on the towing device page 184.
Note

We recommend that you also have your vehicle inspected between service inter-
vals if you tow a trailer frequently.

The handbrake on the towing vehicle must be put on when coupling and decou-
pling the trailer.
Driving Tips
Particular caution is required when towing a trailer.– Do not, as far as possible, drive with your vehicle unladen and the trailer laden.
– Do not make full use of the legal maximum speeds. This applies in particular to downhill sections.
– Apply the brakes in good time.
– Keep a check on the coolant temperature gauge if the outside temperature is high.
Distribution of weight
The distribution of the weight is very poor if your vehicle is unladen and the trailer is
laden. Maintain a particularly low speed if you cannot avoid driving with this combina-
tion.
Driving speed
Do not drive faster than 80 km/hour for safety reasons. This also applies for countries
in which higher speeds are allowed. The fact that the driving stability of the vehicle + trailer combination reduces with
increasing speed means that the legally allowed speed should not be used when there
are unfavourable road, weather or wind cond
itions, particularly near accident black
spots.
You must always reduce your speed immediat ely as soon as you detect even just the
slightest swaying of the trailer. On no account attempt to stop the trailer from
“swaying” by accelerating.
Apply the brakes in good time! If the trailer is fitted with a trailer brake, apply the
brakes gently at first and then brake firmly. This will avoid brake jolts resulting from the
trailer wheels locking. Shift down gears in good time before negotiating a downhill
section to allow the engine to also act as a brake.
Engine overheating
Please keep a check on the coolant temperature gauge if you have to negotiate a
lengthy slope in a low gear at a high engi ne speed when the outside temperature is
very high  page 16, “Coolant temperature gauge”.
If the needle of the coolant temperature gauge moves into the right-hand area or even
the red area of the scale, reduce your speed immediately. Stop and switch off the
engine if the warning light
 in the instrument cluster begins flashing. Wait a few
minutes and check the level of coolant in the coolant expansion bottle page 201,
“Inspecting the coolant level”.
Please refer to the following guidelines  page 31, “Coolant temperature/coolant
level ”.
The coolant temperature can be reduced by switching on the heating.
Any increase in the cooling effect of the coolant fan through shifting down a gear and
increasing the engine speed is not possible since the fan speed is independent of the
engine speed. One should also not drop a gear for this reason when towing a trailer as
long as the engine can manage th e slope without any drop in speed.
