The instrument panel displays the following message 1)
: PLEASE REFUEL! .
Coolant level* / temperature  (red)
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 tempera-
ture is too high.
Coolant temperature too high
The instrument panel displays the following message 1)
: CHECK COOLANT IN-
STRUCTION MANUAL ⇒  page 242.
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 malfunc-
tion of the radiator fan. Check the radiator fan fuse and have it replaced if
necessary ⇒ page 272.
If the control lamp lights up again after driving on for a short distance, stop
the vehicle and switch the engine off . Contact a Technical Service or a spe-
cialised workshop. Coolant level too low
The instrument panel displays the following message
1)
: STOP CHECK COOL-
ANT INSTRUCTION MANUAL.
First look at the coolant temperature gauge. If the needle is in the normal
range, top up with coolant at the earliest opportunity ⇒ 
.
WARNING
● If your vehicle is immobilised for technical reasons, move it to a safe
distance from traffic. Turn the engine off, turn the hazard lights on and
place the warning triangle.
● Never open the bonnet if you can see or hear steam or coolant escap-
ing from the engine compartment. Risk of scalding. Wait until you can no
longer see or hear escaping steam or coolant.
● The engine compartment is a dangerous area. Before carrying out any
work in the engine compartment, switch off the engine and allow it to
cool down. Always note the corresponding warnings ⇒ page 235.

alised workshop. 
Air recirculation mode 
Air recirculation mode prevents fumes or unpleasant smells from coming from the outside.
Fig. 132 On the dash panel: Climatic controls
Air recirculation mode ⇒ Fig. 132 
prevents strong odours in the outside
air from entering the vehicle interior, for example when passing through a
tunnel or in queuing traffic.
With low temperatures outside, the air recirculation increases the effective-
ness of the heating system by warming the air inside the vehicle rather than
the cold air from outside. With high outside temperatures, the air recirculation increases the effective-
ness of the air conditioning system by cooling the air inside the vehicle
rather than the ambient air.
If the windscreen air output is on and the air recirculation mode is pressed,
this remains active. When the recirculation mode is on, if the air distribution
towards the windscreen mode is selected, the recirculation mode is deacti-
vated. For safety reasons, the air recirculation mode should not be connec-
ted.

Air conditioning
With high outside temperatures, the air recirculation increases the effective-
ness of the air conditioning system by cooling the air inside the vehicle
rather than the ambient air.
If the windscreen air output is on and the air recirculation mode is pressed,
this remains active. When the recirculation mode is on, if the air distribution
towards the windscreen mode is selected, the recirculation mode is deacti-
vated. For safety reasons, the air recirculation mode should not be connec-
ted.
WARNING
In air recirculation mode, no cold air from the outside enters the vehicle
interior. If the air conditioning system is switched off, the windows can
quickly mist over. Therefore, never leave the air recirculation mode
switched on for a long time (risk of accident).

General notes
Pollution filter
The pollution filter (a combined particulate filter and active carbon filter)
serves as a barrier against impurities in the outside air, including dust and
pollen.
For the air conditioner to work with maximum efficiency, the pollution filter
must be replaced at the intervals specified in the Service Plan.
If the filter loses efficiency prematurely due to use in areas reaching very
high pollution levels, the pollen filter must be changed more frequently
than stated in the Service Schedule.
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 AC
button is disconnected.
● The outside temperature is lower than approximately +3 °C (+37 °F).
● 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 speci-
alised workshop.
CAUTION
● If you suspect that the air conditioner is damaged, switch it off with but-
ton AC
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
workshop.
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 pud-
dle 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 the vehicle interior and is extracted
by slots designed for this purpose. Therefore, do not cover these slots with
items of clothing or other objects. 

WARNING
● Never start or run the engine in unventilated or closed rooms. The ex-
haust gases contain carbon monoxide, an odourless and colourless poi-
sonous gas. Risk of fatal accidents. Carbon monoxide can cause loss of
consciousness. It can also result in 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 avoid high engine speeds, driving
at full throttle and over-loading the engine. Risk of engine damage.
● The vehicle should not be pushed or towed more than 50 metres to start
the engine. Unburnt fuel could enter the catalytic converter and damage it.
● Before attempting to push-start or tow a vehicle in order to start it, you
should first try to start it using the battery of another vehicle. Note and fol-
low the instructions in ⇒ page 287, Jump-starting.
For the sake of the environment
Do not warm-up the engine by running the engine with the vehicle station-
ary. You should drive off as soon as you start the engine. This helps the en-
gine reach operating temperature faster and reduces emissions. 
Switching off the engine
– Stop the vehicle.
– Turn the ignition key to position ⇒ Fig. 140 0
.
After switching the engine off, the radiator fan may run on for up to 10 mi-
nutes. It is also possible that the fan turns itself on once more if the coolant temperature increases due to the heat accumulated in the engine compart-
ment or due to its prolonged exposure to solar radiation.
WARNING
● Never switch the engine off until the vehicle is completely stationary.
● The brake servo works only when the engine is running. With the en-
gine switched off, more strength is needed to brake. As normal brake op-
eration cannot be performed, risk of accidents and serious injury may ex-
ist.
● The steering lock can be immediately blocked once the key is re-
moved from the ignition. The vehicle cannot be steered. Risk of accident.
CAUTION
When the engine has been running under a heavy load for a long period,
heat can accumulate in the engine compartment and cause engine damage.
For this reason, you should idle the engine for approx. 2 minutes before you
switch it off. 

208Driving and the environment
Note
● If you vehicle has Start-Stop, it is not recommended to switch this func-
tion off.
● It is recommended to close the windows when driving at more than
60 km/h (40 mph)
● Do not drive with your foot resting on the clutch pedal, as the pressure
can make the plate spin, more fuel will be used and it can burn the clutch
plate lining, causing a serious fault.
● Do not hold the vehicle on a hill with the clutch, use the foot brake or
hand brake, using the latter to start. The fuel consumption will be lower and
you will prevent the clutch plate from being damaged.
● On descents, use the engine brake, changing to the gear that is more
suitable for the slope. The fuel consumption will be lower and the brakes
will not suffer. 

Trailer towing
Note
● Towing a trailer places additional demands on the vehicle. We recom-
mend additional services between the normal inspection intervals if the ve-
hicle is used frequently for towing a trailer.
● Find out whether special regulations apply to towing a trailer in your
country. 
Ball coupling of towing bracket*
Depending on the model version, the spherical head on the trailer hook
may be stored in the tool box.
The ball coupling is provided with instructions on fitting and removing the
ball coupling of the towing bracket.
WARNING
The towing bracket ball coupling must be stored securely in the luggage
compartment to prevent them being flung through the vehicle and caus-
ing injury.
Note
● By law, the ball coupling must be removed if a trailer is not being towed
if it obscures the number plate. Driving tips
Driving with a trailer always requires extra care.
Weight distribution
The weight distribution of a loaded trailer with an unladen vehicle is very
unfavourable. However, if this cannot be avoided, drive extra slowly to allow
for the unbalanced weight distribution.
Speed
The stability of the vehicle and trailer is reduced with increasing speed. For
this reason, it is advisable not to drive at the maximum permissible speed
in an unfavourable road, weather or wind conditions. This applies especially
when driving downhill.
You should always reduce speed immediately if the trailer shows the slight-
est sign of snaking. Never try to stop the “snaking” by increasing speed.
Always brake in due course. If the trailer has an overrun brake, apply the
brakes gently at first and then, firmly. This will prevent the jerking that can
be caused by locking of trailer wheels. Select a low gear in due course be-
fore going down a steep downhill. This enables you to use the engine brak-
ing to slow down the vehicle.
Reheating
At very high temperatures and during prolonged slopes, driving in a low
gear and high engine speed, always monitor the coolant temperature gauge
⇒ page 55.
Electronic Stability Control*
The ESC* system helps to stabilise the trailer in case of skidding or rocking. 
