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
Aux. Heating .

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!

 fig. 159 .
– The fuel filler cap on the fuel filler tube must be unlocked to the left using the
vehicle key (only valid for vehicles which do not have automatic unlocking of the
fuel filler flap).
– Unscrew the fuel filler cap anti-clockwise and place the fuel filler cap from above
on the fuel filler flap fig. 159 - right.Closing fuel filler cap– Screw on the fuel filler cap by turning it to the right until it is heard to click.
– The fuel filler cap on the fuel filler tube mu st be locked to the right using the vehicle
key (only valid for vehicles which do not ha ve automatic locking of the fuel filler
flap).
– Close the fuel filler flap until it locks.
The correct grade of fuel for your vehicle as well as the tyre size and inflation pressures
are stated on a sticker affixed to the inside of the fuel filler flap. Further information on
fuel page 192. The fuel tank has a capacity of about 55°litres or 60 litres
17).
WARNING
Pay attention to any legal requirements if
you do carry a spare canister in the
vehicle. We do not recommend carrying any fuel canisters in your vehicle for
safety reasons. The canister can be damaged in the event of an accident and fuel
may leak out.
Caution

Before refuelling it is necessary to switch off the auxiliary heating system (auxiliary
heating and ventilation) *.

Remove any fuel which has spilled onto th e paintwork of your vehicle immediately
- risk of paint damage!

On vehicles fitted with a ca talytic converter, never let the fuel tank run completely
empty. An irregular supply of fuel to the engine can result in misfiring and unburnt fuel
may get into the exhaust system, which may result in overheating and damage to the
catalytic converter.

Make sure that the valve is not pressed into the filler tube when inserting the pump
nozzle into the filler tube. Otherwise you ar e unintentionally filling up the volume,
which in case of heat can cause an expansion of the fuel. This can lead to an overflow
of fuel or damage to parts of the fuel reservoir.

The fuel tank is full just as soon as the pump nozzle switches off for the first time,
provided the nozzle has been operated properly. Do not continue refuelling - other-
wise the expansion volume is filled up.
