Heating and air conditioning system
76
Recirculated air mode
In recirculated air mode air is sucked out of the interior of the vehicle
and then fed back into the interior.Recirculated air mode prevents polluted air outside the vehicle from getting into the
vehicle, for example when driving through a tunnel or when standi ng in a traffic jam.Switching recirculated air mode on– Press the button page 74, fig. 82 the warning light lights up in the
button.Switching recirculated air mode off– Once again press the button . The wa rning light in the button goes out.
The recirculated air mode is switched off automatically if the air distribution control
is in position
  page 74, fig. 82 . You can also switch recirculated air mode on again
from this setting by repeatedly pressing pushbutton .
WARNING
You should not leave recirculated air mode on over a longer period of time, as
“stale” air may result in fatigue in the driver and occupants, divert your atten-
tion and also cause the windows to mist up. The risk of having an accident
increases. Switch recirculated air mode off as soon as the windows begin
misting up.Using the air conditioning system economicallyThe compressor on the air conditioning syst em uses power from the engine when in
cooling mode which will effect the fuel consumption.
It recommended to open the windows or the doors of a vehicle for which the interior
has been strongly heated through the effect of direct sunlight in order to allow the
heated air to escape.
The cooling system should not be switched on while travelling when the window is
open. The desired interior temperature can also be achieved without switching in the cooling
system just by switching to fresh air mode.
For the sake of the environment
When you economize on fuel, you
also reduce pollutant emissions.Operational malfunctionsIf the cooling system does not operate at outside temperatures higher than +5 °C,
there is a problem in the system. The reasons for this may be:
The fuse on the air conditioning system has blown. Check the fuse, replace it if
necessary page 169.

The cooling system has switched off auto matically for a short time because the
coolant temperature of the engine is too hot  page 16.
If you are not able to rectify the operational problem yourself, or if the cooling capacity
decreases, switch the cooling system off. Contact a specialist garage.

Technical Data

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
away and 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 169.

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
away and 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 169.

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 tu rning the ignition key into position
 page 77, fig. 84 .
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.

Reducing idling
Idling also costs fuel.It is worthwhile switching off the engine in a traffic jam or when waiting at a level
crossing or at traffic lights with a lengthy red phase. Even after just 30 - 40 seconds you
will have saved more fuel th an that is needed when you start the engine up again.
If an engine is only idling it takes much longer for it to reach its normal operating
temperature. Wear-and-tear an d pollutant emissions, though, are particularly high in
the warming-up phase. This is why you should drive off right after starting the engine.
Do avoid high engine revolu tions at this time, however.Regular servicing
A poorly tuned engine consumes an unnecessarily high amount of fuel.Having your vehicle serviced regularly at a specialist garge enables you to satisfy one
of the requirements for economical motoring even before you set off on your journey.
Keeping your vehicle properly serviced not on ly has a positive effect on the safety of
your vehicle and maintaining its value, but also saves on fuel.
A poorly tuned engine can result in a fu el consumption which is 10 % higher than
normal.
The foreseen maintenance work should be undertaken exactly according to the
Service schedule by a specialist garage.
Also check the oil level after refuelling. Oil consumption is dependent to a consider-
able extent on the load and speed of the en gine. Oil consumption could be as high as
0.5 litres/1 000 km depending on your style of driving.
It is quite normal that a new engine has a higher oil consumption at first, and reaches
its lowest level only after a certain running in time. It is therefore not possible to
correctly assess the oil consum ption of a new vehicle until after you have driven about
5 000 km.
For the sake of the environment

You can achieve additional improvements in your fuel economy by using high-
lubricity oils.

Check the ground below your vehicle at regu lar intervals to detect any leakages in
good time. Please have your vehicle inspected by a specialist garge if you find any
stains caused by oil or other fluids on the floor.
Avoid driving short distances
Short distances result in an above-average high fuel consumption.– Avoid driving a distance of no more than 4 km if the engine is cold.
The engine and catalytic converter mu st first have reached their optimal operating
temperature in order to effectively reduce fuel consumption and pollutant emissions.
The cold engine vehicle cons umes approx. 15 - 20 litres/100 km of fuel immediately
after starting. Fuel co nsumption drops to 10 litres/100 km after just 1 kilometre. The
engine reaches its operating temperat ure (outside temperature and engine
dependent) only after about 4 to 10 kilometres and the fuel consumption then stabi-
lizes. You should therefore avoid driving short distances whenever possible.
An important factor in this connection is also the ambient temperature. The
 fig. 116 shows the different fuel consumptions for the same distance, on the one
hand at +20 °C and on the other hand at -10 °C. Your vehicle has a higher fuel
consumption in winter than in summer.
