The engine compartment of any motor vehicle is a dangerous area!
Before you open the bonnet to work on the engine or in the engine compart-
ment, you must switch off the engine and allow it to cool to reduce the risk
of scalding or other injuries. Read and observe the relevant warnings
⇒ page 198.Note
•
The appropriate warning lamp for a fault will light up in vehicles without
warning or information texts in the display.
•
In vehicles with warning or information texts in the display, the appro-
priate warning lamp for a fault will ligh t up and a warning or information text
will also appear in the display.
Fuel level / reserve

This symbol lights up to indicate that the fuel tank is down to
the reserve level.This lights when only 7 litres of fuel remain in the tank. Also, an audible
warning is given. This serves as a reminder to fill up with fuel at the earliest
opportunity ⇒page 195.
The message displayed in the instrument panel display is
8): PLEASE
REFUEL .
Coolant Level* / temperature

The warning lamp lights up if the coolant temperature is too
high or if the coolant level is too low.There is a fault if:•
The warning symbol does not go out again after a few seconds.
•
The warning lamp lights up or flashes while the vehicle is moving, while
three acoustic warning signals ⇒ are emitted.
This means that either the coolant level is too low or the coolant temperature
is too high.
Coolant temperature too high
The following text is displayed in the instrument panel display
9): CHECK
COOLANT! INSTRUCTIONS MANUAL .
First look at the coolant temperature gauge. The coolant temperature is too
high if the needle is over the warning area on the dial. Stop the vehicle,
switch off the engine and wait for it to cool down. Check the coolant level.
If the coolant level is correct, the over heating may be caused by a malfunction
of the radiator fan. Check the radiator fan fuse and have it replaced if neces-
sary ⇒page 232.
If the warning lamp lights up again after driving on for a short distance, stop
the vehicle and switch off the engine . Contact an Authorised Service Centre
or a qualified workshop.

Heating, Ventilation and Air conditioning
144
– Use the air distribution control to guide the flow of air in the required direction: (to the windscreen), (to the upper
body), (to the foot well) and (to the windscreen and to the
foot well).Heating system
Maximum heat output, which is needed to defrost the windows quickly, is
only available when the engine has reached its operating temperature.
Air conditioner
When the air conditioning system is switched on, not only the temperature,
but also the air humidity in the vehicle interior is reduced. This improves comfort for the vehicle occupants and prevents misting of the windows when
the ambient air humidity is high.
If
the air conditioning syst em cannot be switched on, this may be caused by
the following reasons:
•
The engine may not be running.
•
The blower is switched off.
•
The ambient air temperature is lower than +3°C.
•
The air conditioning system compressor has been temporarily switched
off because the engine coolant temperature is too high.
•
The air conditioner fuse is faulty.
•
Another fault in the vehicle. Have the air conditioner checked by a quali-
fied workshop.
Air recirculation mode
Air recirculation mode prevents fumes or unpleasant smells from entering the vehicle.

Glow plug system for the diesel engine
To avoid unnecessary load on the battery, do not use any other major elec-
trical equipment while the
glow plugs are pre-heating.
Start the engine as soon as the glow plug warning lamp ⇒page 81 goes out.
Starting the engine after the fuel tank has been completely run dry
If the fuel tank has been completely ru n dry, it may take longer than normal
(up to one minute) to start the engine af ter refuelling with diesel fuel. This is
because the system must eliminate air first.
WARNING
•
Never start or run the engine in unventilated or closed rooms. The
exhaust fumes contain carbon monoxide, an odourless and colourless
poisonous gas. Risk of fatal accidents. Carbon monoxide can cause loss of
consciousness. It can also cause death.
•
Never leave the vehicle unattended if the engine is running.
•
Never use “cold start sprays”, they could explode or cause the engine
to run at high revs. Risk of injury.Caution
•
When the engine is cold, you should avo id high engine speeds, driving at
full throttle and over-loading th e engine. Risk of engine damage.
•
The vehicle should not be pushed or towed for more than approximately
50 metres to start the engine. Fuel could enter the catalytic converter and
damage it.
•
Before attempting to push-start or tow a vehicle to start it, you should first
try to start it using the battery of another vehicle. Note and follow the instruc-
tions ⇒ page 248, “Jump-starting”.
For the sake of the environment
Do not warm up the engine by running the engine with the vehicle stationary.
You should drive off as soon as you start the engine. This helps the engine
reach operating temperature faster and reduces emissions.Switching off the engine– Stopping the engine.
– Turn the ignition key to position ⇒page 152, fig. 115 .After the engine is switched off the radiator fan may run on for up to 10
minutes, even if the ignition is switched of f. It is also possible that it will turn
itself on once more if the temperature of the coolant increases due to the
elimination of built-up heat in the engine compartment or if this is heated due
to prolonged exposure to the heat of the sun.
WARNING
•
Never switch off the engine until the vehicle is stationary.
•
The brake servo works only when the engine is running. You will need
more strength to brake the vehicle when the engine is switched off. As you
cannot brake in the normal manner, there is a greater risk of accidents and
serious injury.
•
The steering lock can engage immediately when the key is removed
from the ignition lock. The vehicle cannot be steered. Risk of accident.
