serious personal injury or damage to your vehicle.•The risk of an accident increases if your vehicle breaks down. Use a
warning triangle to draw the attention of other road users in order to
prevent danger to third parties.•The engine compartment is a dangerous area! Before you open the
bonnet to work on the engine or in the engine compartment, you must
switch the engine off and allow it to cool to reduce the risk of scalding or
other injuries. Read and observe the relevant warnings ⇒page 221.Note
•The appropriate warning lamp for a fault will light up in vehicles without
warning or information messages in the display.•In vehicles with warning or information texts on the screen, the appro-
priate warning lamp for a fault will light up and a warning or information
message will also appear on the screen.Warning symbolsThere are red warning symbols (p riority 1) and yellow warning
symbols (priority 2)Warning reports, Priority 1 (red)
If one of these faults occurs, the warning lamp will flash or light up and will
be accompanied by three audible warnings . This is a danger warning. Stop
the vehicle and switch off the engine. Check the fault and correct it. Obtain
professional assistance if necessary.

82Fuel level / reserve
z
This symbol lights up to indicate that the fuel tank is under
the reserve level.It lights up when only 7 litres of fuel remain in the tank. You will also hear a
warning signal. It reminds you to fuel up the fuel tank as soon as possible
⇒ page 214.
The instrument panel displays the following message
11): PLEASE REFUEL! .
Coolant level* / temperature
v
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, and
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 instrument panel displays the following message
12): CHECK COOLANT
INSTRUCTION MANUAL ⇒ page 228.
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 the engine off and wait for it to cool down. Check the coolant level.
If the coolant level is correct, the overheating may be caused by a malfunction
of the radiator fan. Check the radiator fan fuse and have it replaced if neces-
sary ⇒page 254.
If the warning lamp lights up again after driving on for a short distance, stop
the vehicle and switch the engine off . Contact an Authorised Ser vice Centre

Air conditioning
152
– Use the air distribution control to guide the flow of air in the required direction: (to the windscreen), (to the upper
body), (to the footwell) and (to the windscreen and to the
footwell).Heating
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 system cannot be switched on this may be caused by
the following reasons:
•The engine is not running.•The blower is switched off.•The outside temperature is below +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 special-
ised workshop.
Air recirculation mode
Air recirculation mode prevents fumes or unpleasant smells from coming from the outside.

comfort for the vehicle occupants and prevents misting of the windows when
the ambient air humidity is high.
If the air conditioning system cannot be switched on this may be caused by
the following reasons:
•The engine is not running.•The button is disconnected.•The outside temperature is below +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 special-
ised workshop.Caution
•If you suspect that the air conditioner is damaged, switch it off with the button to prevent further damage and have it checked by a specialised
workshop.•Repairs to the air conditioner require specialist knowledge and special
tools. Therefore, we recommend you to take the vehicle to a specialised work-
shop.Note
•If the humidity and temperature outside the vehicle are high, condensa-
tion can drip off the evaporator in the cooling system and so forming a puddle
underneath the vehicle. This is completely normal and there is no need to
suspect a leak.•Keep the air intake slots in front of the windscreen free of snow, ice and
leaves to ensure heating and cooling are not impaired, and to prevent the
windows from misting over.
•The air from the vents flows through th e vehicle interior and is extracted
by slots designed for this purpose. Therefore, do not cover these slots with
items of clothing or other objects.•The air conditioner operates most effectively with the windows and the
sliding/tilting sunroof* closed. However, if the temperature inside the vehicle
is excessive because of the sun, the air inside can be cooled faster by opening
the windows for a short time.•Do not smoke while air recirculation mode is on, as smoke drawn into the
air conditioning system leaves a residue on the evaporator, producing a
permanent unpleasant odour.•It is advisable to connect the air conditioning at least once a month, to
lubricate the system gaskets and prevent leaks. If a decrease in the cooling
capacity is detected, an Authorised Service Centre should be consulted to
check the system.
