Engine revolutions counter The red zone of the rev counter scale
1 ⇒ fig. 2
indicates the range in which the
engine control unit begins to limit the engine speed. The engine control unit re-
stricts the engine speed to a steady limit value.
Shift into the next higher gear or select the selector lever position D of the auto-
matic gearbox before reaching the red zone of the rev counter scale.
Avoid high engine speeds during the driving time and before the engine has been
warmed up to operating temperature ⇒ page 161
. For the sake of the environment
Shifting to a higher gear in good time helps to reduce the fuel consumption, mini-
mises operating noise levels, protects the environment and contributes to a lon-
ger life and reliability of the engine. 
Speedometer Warning against excessive speeds
An acoustic warning signal will sound when the vehicle speed exceeds 120 kilo-
metres per hour. The acoustic warning signal will switch off again when the vehi-
cle speed goes below this speed limit.

Coolant temperature gauge The coolant temperature gauge
3
⇒  fig. 2
operates only when the ignition is
switched on. 6 Please pay attention to the following guidelines regarding temperature ranges in
order to avoid damage to the engine:
Cold range
If the pointer is in the left-hand area of the scale it means that the engine has not
yet reached its operating temperature. Avoid running at high engine speeds, at
full throttle and at severe engine loads.
The operating range
The engine has reached its operating temperature as soon as the pointer moves
into the mid-range of the scale. The pointer may also move further to the right at
high engine loads and high outside temperatures. This is not critical provided the
warning symbol  in the instrument cluster does not flash.
If the symbol  in the instrument cluster flashes it means that either the coolant
temperature is too high or the coolant level is too low. Please refer to the guide-
lines ⇒ page 25, Coolant temperature/ Coolant quantity . WARNING
Pay attention to the warning notes ⇒ page 181, Working in the engine com-
partment
before opening the bonnet and inspecting the coolant level. CAUTION
Additional headlights and other attached components in front of the fresh air inlet
impair the cooling efficiency of the coolant. There is then a risk of the engine
overheating at high outside temperatures and high engine loads! 
Fuel gauge The fuel gauge
6
⇒
 fig. 2 only operates when the ignition is switched on.
The fuel tank has a capacity of about 55 litres or 60 litres 2)
. The warning symbol 
in the instrument cluster lights up when the pointer reaches the reserve marking.
There are now about 9 litres of fuel remaining in the tank. This symbol is a re-
minder for you, that you must refuel .

Do not continue your journey
if for some reason it is not possible under the con-
ditions prevailing to top up with coolant. Keep the engine switched off and obtain
professional assistance from a specialist garage, otherwise it could lead to severe
engine damage.
If the coolant is within the specified range, the increased temperature may be
caused by an operating problem at the coolant fan. Check the fuse for the coolant
fan, replace it if necessary ⇒
 page 212, Fuse assignment in engine compartment.
Do not continue driving if the warning light does not go off although the fluid is
at the correct level and also the fuse of the fan is in proper order. Contact a spe-
cialist garage to obtain assistance.
Please refer to the following guidelines ⇒ page 184, Cooling system.
The following text will be displayed in the information display: Check coolant! Owner's manual! Check coolant! Car documentation! WARNING
● If you must stop for technical reasons, then park the vehicle at a safe dis-
tance from the traffic and switch off the engine and switch on the hazard
warning light system ⇒ page 49.
● Take care when opening the coolant expansion bottle. If the engine is hot,
the cooling system is pressurized - risk of scalding! It is best to allow the en-
gine to cool down before removing the cap.
● Do not touch the coolant fan The coolant fan may switch on automatically
even if the ignition is off. 
Traction control system (TCS) The warning light
 comes on for a few seconds when the ignition is switched on.
The warning light comes on when driving when a control cycle is activated.
The warning light lights up permanently if there is a fault in the TCS system.
The fact that the TCS system operates together with the ABS means that the TCS
warning light will also come on if the ABS system is not operating properly.
If the warning light 
comes on immediately after starting the engine, the TCS
system can be switched off for technical reasons. In this case, the TCS system can
be switched on again by switching the ignition on and off. If the warning light
goes out, the TCS system is fully functional again.
Further information about the TCS ⇒ page 156, Traction control system (TCS)

. Note
If the battery has been disconnected and reconnected, the warning light  comes
on after switching on the ignition. The warning light must go out after driving a
short distance. 
Anti-spin regulation (ASR)  The TCS system is switched off by pressing the button
⇒ fig. 139 and the warning
light  lights up. 
Electronic stability programme (ESP)  The warning light
 comes on for a few seconds when the ignition is switched on.
When the ESP helps to stabilise the vehicle, the warning light  flashes in the in-
strument cluster.
The warning light lights up permanently if there is a fault in the ESP system.
The fact that the ESP system operates together with the ABS means that the ESP
warning light will also come on if the ABS system is not operating properly.
If the warning light  comes on immediately after starting the engine, the ESP
system can be switched off for technical reasons. In this case, the ESP system can
be switched on again by switching the ignition on and off. If the warning light
goes out, the ESP system is fully functional again.
Further information on the ESP ⇒

 page 154, Electronic stability programme (ESP).
Electronic Differential Lock (EDL)
The EDL is a part of the ESP. A fault in the EDL is indicated by the lighting up of
the ESP warning light in the instrument cluster. Have the vehicle inspected imme-
diately by your specialist garage. Further information on the EDL ⇒ page 155,
Electronic Differential Lock (EDL and XDL). Note
If the battery has been disconnected and reconnected, the warning light  comes
on after switching on the ignition. The warning light must go out after driving a
short distance. 26

Heating and air conditioning system
Introduction
Description and information The heating effect is dependent upon the coolant temperature, thus full heat out-
put only occurs when the engine has reached its operating temperature.
If the cooling system is switched on, the temperature and air humidity drops in
the vehicle. The well-being of the occupants of the car is enhanced as a result of
this particularly at high outside temperatures and a high air humidity. The system
prevents the windows misting up during the cold season of the year.
It is possible to briefly activate recirculated air mode in order to enhance the cool-
ing effect - air-conditioning system ⇒ page 90
, Climatronic ⇒ page 93.
The air inlet in front of the windscreen must be free of ice, snow or leaves in order
to ensure that the heating and cooling systems operate properly.
After switching on the cooling Condensation from the evaporator of the air condi-
tioning may drip down and form a puddle below the vehicle. This is quite normal
and not an indication of a leak! WARNING
● For your own safety and that of other road users, ensure that all the win-
dows are free of ice, snow and misting. Please familiarize yourself about how
to correctly operate the heating and ventilation systems, how to demist and
defrost the windows, as well as with the cooling mode.
● 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 at-
tention 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. Note
● The used air streams out through the air removal openings in the luggage
compartment.
● We recommend that you do not smoke in the vehicle when the recirculating air
mode is operating since the smoke which is drawn at the evaporator from the in-
terior of the vehicle forms deposits in the evaporator of the air conditioning sys- tem. This produces a permanent odour when the air conditioning system is oper-
ating which can only be eliminated through considerable effort and expense (re-
placement of compressor).
● Please refer to the information regarding the recirculated air mode for heating
⇒

  page 88 and/or for air-conditioning system ⇒ page 90 or Climatronic
⇒  page 93.
● To ensure the heating system, air conditioning system or Climatronic work per-
fectly, the air outlet vents must not be covered by any objects. 
Using the air conditioning system economically The compressor on the air conditioning system 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 inte-
rior has been strongly heated through the effect of direct sunlight in order to al-
low 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 problems If 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 211.
● The cooling system has switched off automatically for a short time because
the coolant temperature of the engine is too hot ⇒ page 11.
If you are not able to rectify the operational problem yourself, or if the cooling ca-
pacity decreases, switch the cooling system off. Contact a specialist garage.  85

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 in-
creases. Switch recirculated air mode off as soon as the windows begin mist-
ing up. 
Climatronic (automatic air conditioning) Description The Climatronic system is an automatic heating, fresh air and cool-
ing system which provides optimal comfort for the occupants of the
car.
The Climatronic maintains fully automatically a convenience temperature. This is
achieved by automatically varying the temperature of the outflowing air, the
blower stages and the air distribution. The system also takes into account sun-
light which eliminates the need to alter the settings manually. The automatic
mode
⇒

 page 92 ensures maximum well-being of the occupants at all times of
the year.
Description of Climatronic system
The cooling operates only if the following conditions are met:
● engine running,
● outside temperature above approx. +2 °C,
● AC switched on.
The AC compressor is switched off at a high coolant temperature in order to pro-
vide cooling at a high load of the engine.
Recommended setting for all periods of the year:
● Set the desired temperature, we recommend 22 °C.
● Press the button AUTO
⇒  fig. 95 .
● Move the air outlet vents 3 and 4 so that the air flow is directed slightly up-
wards. Note
● We recommend that you have Climatronic cleaned by a specialist garage once
every year.
● On vehicles equipped with a factory-fitted radio or radio navigation system,
the information of the Climatronic is also shown on the display. This function can
be switched off, see operating instructions of the radio or the radio navigation
system. 

Auxiliary heating (auxiliary heating and ventilation)
Description and important information The auxiliary heating (auxiliary heating and ventilation) heats or
supplies the interior of the vehicle with fresh air independent of the
engine.
Auxiliary heating (parking heating)
The auxiliary heater (parking heater) functions in connection with the air-condi-
tioning system or Climatronic.
It can be used when stationary, when engine is switched off for preheating of the
vehicle as well as while driving (e.g. during the heating phase of the engine).
The engine is also preheated when the vehicle is stationary and the engine is
switched off, if the auxiliary heating is switched on.
The auxiliary heating (parking heating) warms up the coolant during the combus-
tion of fuel from the vehicle tank. The coolant warms up the air, which (if the
blower speed is not set to zero) flows into the occupant compartment.
Auxiliary ventilation
The auxiliary ventilation enables fresh air to flow into the vehicle interior by
switching off the engine, whereby the interior temperature is effectively de-
creased (e.g. with the vehicle parked in the sun). WARNING
● The auxiliary heating must never be operated in closed rooms - risk of poi-
soning!
● The auxiliary heating must not be running 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 vehicle, if you wish to operate the aux-
iliary heating, in such a way that the exhaust gases of the auxiliary heating
can come easily into contact with inflammable materials (e.g. dry grass) or
easily inflammable substances (e.g. fuel run out). Note
If the auxiliary heating runs, the fuel consumption comes from the vehicle tank.
The auxiliary heating automatically controls the filling level in the fuel tank. If only
a low quantity of fuel is present in the fuel tank, the function of the auxiliary heat-
ing is blocked.
● 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 discharg-
es. If the auxiliary heating and ventilation has been operated several times over a
longer period, the vehicle must be driven a few kilometers 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 pe-
riod.
● The auxiliary heating and ventilation does not switch on or comes on, if the
vehicle battery indicates a low loading state ⇒

 page 190, Automatic consumer
shut-off.
● The auxiliary heating (parking heating) does not switch on, if the following was
shown in the information display or before switching off the ignition: Please re-
fuel!
● 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 vehicle interior after switching on the auxili-
ary heating, you must maintain the comfort temperature normally selected by you
and leave the air outlet vents in an open position. It is recommended to put the air
flow in the position  or . 94
Heating and air conditioning system

CAUTION
● The starter may only be operated (ignition key position 3 ), if the engine is not
running. If the starter is immediately 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 operating temperature - risk of damag-
ing the engine!
● Do not tow start the engine - danger of damaging the engine. On vehicles with
a catalytic converter, unburnt fuel may get into the catalytic converter where it
may ignite. This in turn may damage or destroy the catalytic converter. You can
use the battery of another vehicle as a jump-start aid ⇒ page 206
, Jump-starting.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 emissions are lower. 
Petrol engines These 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 electrical fuel pump is defect if the engine
still does not start. Check the fuse and replace it if necessary ⇒ page 211.
● 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 engines Glow 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 temper-
ature.
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 211.
● 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 turning the ignition key into position 1 ⇒ 
fig. 99 . WARNING
● Never switch off the engine before the vehicle is stationary - risk of acci-
dent!
● The brake booster only operates when the engine is running. Greater
physical effort for braking is required when engine 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 al-
lowed it to run at idling speed for about 2

minutes. This prevents any accumula-
tion of heat when the engine is switched off. £100
