Engine revolutions counter
The red zone of the rev counter scale ⇒page 10, fig. 2 indicates the range in
which the engine control unit begins to li mit the engine speed. The engine control
unit restricts the engine speed to the 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 187.
For the sake of the environment
Shifting up early helps yo u save fuel and reduce the operating noise of your
vehicle.
Speedometer
Warning against excessive speeds*
An acoustic warning signal will sound wh en the vehicle speed exceeds 120 kilome-
tres per hour. The acoustic warning signal will switch off again when the vehicle
speed goes below this speed limit.
Note
This function is only valid for some countries.
Coolant temperature gauge
The coolant temperature gauge ⇒page 10, fig. 2 operates only when the igni-
tion is switched on.
In order to avoid any damage to the engine , please pay attention to the following
notes regarding the temperature ranges: 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 temp erature. 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 pointe r 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. Observe the guidelines
⇒ page 31, “Coolant temperature/ Coolant quantity ”.
WARNING
Pay attention to the warning notes ⇒page 209, “Working in the engine
compartment” before opening the bonn et and inspecting the coolant level.
Caution
Additional headlights and other attached co mponents in front of the fresh air inlet
impair the cooling efficiency of the coolant. There is then a risk of the engine over-
heating at high outside temper atures and high engine loads!
Fuel gauge
The fuel gauge ⇒page 10, fig. 2 only operates when the ignition is switched on.
The fuel tank has a capacity of ab out 60 litres. The warning symbol
 in the instru-
ment 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 reminder for you, that
you must refuel .
The following will be displayed in the information display*: Please refuel! (Please refuel!)

•If you do not pay attention to the warning lights coming on and the corre-
sponding descriptions and warning notes, this may result in severe body
injuries or major vehicle damage.
•The engine compartment of your car is a hazardous area. There is a risk
of injuries, scalding, accidents and fire when working in the engine
compartment, e.g. inspecting and replenis hing oil and other fluids. It is also
essential to observe all warnings ⇒page 209, “Working in the engine
compartment”.
Note
•The arrangement of the indicator light is dependent on the model version. The
symbols shown in the following functional description are to be found as indicator
lights in the instrument cluster.
•Operational faults are shown in the instrument cluster as red symbols (priority
1 - danger) or yellow symbols (priority 2 - warning).
Turn signal system 
Either the left  or right  indicator light flashes depending on the position of the
turn signal lever.
The indicator light flashes at twice its normal rate if a turn signal light fails. This does
not apply when towing a trailer.

Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
If the
warning light
 begins to flash while driving, a fault exists in the engine
control. The engine management system selects an emergency programme which
enables you to drive to the nearest specialist garage by adopting a gentle style of
driving.
The following text will be displayed in the information display*:
Engine fault Workshop!
Coolant temperature/ Coolant quantity 
The warning light  comes on for a few seconds 4) w h e n th e i g ni t i o n i s s w i t c h e d o n .
The coolant temperature is too high or the coolant level too low if the warning light
 does not go out or flashes while driving.
3 peeps sound as an additional warning signal.
In this case stop and switch the engine off and check the coolant level; top up the
coolant as necessary.
Do not continue your journey if for some reason it is not possible under the
conditions 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 242, “Fuse assignment in engine compartment -
version 1” or ⇒ page 244, “Fuse assignment in en gine compartment - version 2”.
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 fa n is in proper order. Contact a specialist
garage to obtain assistance.
Please also refer to the additional instructions ⇒page 213, “Cooling system”. The following text will be displayed in the information display*:
Check coolant! Owner's manual
WARNING
•If you must stop for technical reasons, then park the vehicle at a safe
distance from the traffic and switch off the engine and switch on the hazard
warning light system ⇒ page 59.
•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
engine to cool down before removing the cap.
•Do not touch the coolant fan The coolant fan may switch on automati-
cally 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 will come on and remains on if the TCS is switched off or if there
is a fault in the 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 swit ching the ignition on and off. If the warning light goes
out, the TCS system is fully functional again.
Further information about the TCS ⇒page 181, “Traction control system (TCS)”.
Note
If the battery has been disconnected and reconnected, the warning light  comes
on after switching on the ignition. The warn ing light must go out after driving a short
distance.4)The warning light  on vehicles fitted with information display does not come on after
switching the ignition on, but only if the coolant temperature is too high or the coolant level
is too low.

The air conditioning system
Climatic* (semi-automatic air conditioning system)
Description
The Climatic is a combined cooling and heating system. It makes it
possible to optimally control the air temperature at any season of the
year.
Description of the Climatic
It is important for your safety and for your driving comfort that the Climatic is oper-
ating properly.
The cooling only operates if button ⇒page 97, fig. 110 is pressed, and the
following conditions are met:
•engine running,
•outside temperature above +2°C and
•blower switch switched on (positions 1 to 4).
If the cooling system is switched on, the temperature and air humidity drops in the
vehicle. The wellbeing 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.
The heating effect is dependent upon th e coolant temperature, thus full heat
output only occurs when the engine has reached its operating temperature.
It is possible to briefly activate recirc ulated air mode in order to enhance the
cooling effect ⇒.
Air at a temperature of about 5°C may flow out of the vents under certain circum-
stances when the cooling system is operating. Lengthy and uneven distribution of
the air flow out of the vents and large differences in temperature, for example when
getting out of the vehicle, can resu lt in chills in sensitive persons.
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
windows are free of ice, snow and mist ing. Please familiarize yourself about
how to correctly operate the heating an d 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 attention 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
•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 inte-
rior of the vehicle forms deposits in the evaporator of the air conditioning system.
This produces a permanent odour when th e air conditioning system is operating
which can only be eliminated through co nsiderable effort and expense (replace-
ment of compressor).

The air conditioning system
100
Redirecting air flow
– The horizontal as well as the vertical direction of the air flow is set with
the handle in the middle of the air outlet vents.
You can set the air supply to the individual air outlet vents using the control dial
⇒ page 97, fig. 110 . The air outlet vents 2 , 3 ⇒ page 99, fig. 111 and 5 ⇒ page 99,
fig. 112 can also be closed and opened individually.
Unwarmed or cooled air will flow out of the air outlet vents according to the setting
of control dial ⇒page 97, fig. 110 and the atmosphe ric conditions.
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 th e doors of a vehicle for which the inte-
rior has been strongly heated through the ef fect 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 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 241.
•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 operat ional problem yourself, or if the cooling
capacity decreases, switch the cooling sy stem off. Contact a specialist garage.
Climatronic* (automatic air conditioning)
Description
The Climatronic system is a combination of an automatic heating,
fresh air and cooling 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 temper ature of the outflowing air, the blower
stages and the air distribution. The system also takes into account sunlight which
eliminates the need to alter the settings manually. The automatic mode
⇒ page 102 ensures maximum wellbeing 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 +2°C,
• switched on.
If the cooling system is switched on, the temperature and air humidity drops in the
vehicle. The wellbeing 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.
The heating effect is dependent upon th e coolant temperature, thus full heat
output only occurs when the engine has reached its operating temperature.
It is possible to briefly activate recirculated air mode in order to enhance the
cooling effect ⇒page 103.

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.
The AC compressor is switched off at a hi gh coolant temperature in order to provide
cooling at a high load of the engine.
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!
Recommended setting for al l periods of the year:
•Set the desired temperature, we recommend 22 °C.
•Press the button ⇒page 102, fig. 113 .
•Move the air outlet vents 2 and 3 so that the air flow is directed slightly upwards.
Aeration of the vehicle when ignition is switched off*
On models fitted with power sliding/tilting roof with sollar cells, the fresh air blower
is automatically switched over to “solar mode” if the sun ray's are sufficient after
switching off the ignition. The solar cells on the sliding/tilting roof deliver power for
the fresh air blower. This supplies the interior of the car with fresh air.
For an optimum ventilation, the air outlet vents 2 and 3 must be opened
⇒ page 105, fig. 114 .
The ventilation functions only when the sliding/tilting roof is closed.
WARNING
•For your own safety and that of other road users, ensure that all the
windows are free of ice, snow and mistin g. Please familiarize yourself about
how to correctly operate th e 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 attention 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
•If the cooling system has not been switched on for a lengthy period, odours may
be produced at the evaporator because of deposits. Switch the cooling system on
at least once a month for approximately 5 mi nutes at the highest blower stage - also
during the cold season of the year - in order to remove such odours. Also open a
window for a short time.
•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 inte-
rior of the vehicle forms deposits in the ev aporator of the air conditioning system.
This produces a permanent odour when th e air conditioning system is operating
which can only be eliminated through co nsiderable effort and expense (replace-
ment of compressor).
•The used air streams out through the air removal openings in the luggage
compartment.
•On vehicles equi pped with a factory-fitted radio* or navigation*, the informa-
tion of the Climatronic is also shown on the display. You can switch off this function
for the Radio* - see operating instructio ns for radio. This function cannot be
switched off during Navigation*.

The air conditioning system
106
Auxiliary heating (auxiliary heating and ventilation)*
Description and important information
The auxiliary heating (auxiliary he ating and ventilation) heats or
supplies the interior of the vehicl e with fresh air independent of the
engine.
Auxiliary heating (auxiliary heating)
The auxiliary heating (auxiliary heating) func tions in connection with the Climatic or
Climatronic.
It can be used when stationary, when engi ne is switched off for preheating of the
vehicle as well as while driving (e.g. during the heating phase of the engine).
The auxiliary heating (auxiliary 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.
10)
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 decreased
(e.g. with the vehicle parked in the sun).
WARNING
•The auxiliary heating must never be op erated in closed rooms - risk of
poisoning!
•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
auxiliary 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.
Therefore the auxiliary heating should not be operated, if there is very little fuel in
the tank.
•The exhaust pipe of the auxiliary heatin g, 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 discharges.
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
period.
•The auxiliary heating and ventilation does not switch on or comes on, if the
vehicle battery indicates a low loading state.
•The auxiliary heating (auxiliary heating) switches off, if in the information
display: Please refuel! is indicated or wa s indicated before switching off the igni-
tion.
•When driving, the auxiliary heating can only be switched on, if the exterior
temperature is lower than 5 °C.
•The air inlet in front of the windscreen must be free of ice, snow or leaves in
order to ensure that the auxili ary heating operates properly.
•So that warm air can flow into the vehi cle interior after switching on the auxil-
iary heating, you must maintain the te mperature normally selected by you (we
recommend 22°C). It is recommended to put the air flow in the position
.
•On vehicles with DPF (diesel particle filter) the warm coolant heats up the
engine.
10)However the coolant does not warm up the engine.

Starting-off and Driving
112
Starting the engine
General
You can only start the engine only using an original ignition key.
•Place the gearshift lever into neutral (or place the selector lever to the position
P or N in the case of an automatic gearbox) and put on the handbrake firmly before
starting the engine.
•The clutch pedal should be fully depressed when starting the engine which
means that the starter only has to crank the engine.
•Let go of the key as soon as the engine starts otherwise there may be damage
to the starter.
The engine running noises ma y louder at first be louder for a short time after
starting the cold engine until oil pressure can be built up in the hydraulic valve
clearance compensation. This is quite no rmal and is not an operating problem.
If the engine does not start ...
You can use the battery of anothe r vehicle as a jump-start aid ⇒page 236.
It is only possible to tow-start vehicles fitted with a manual gearbox. The tow-
starting distance must not be more than 50 metres.
WARNING
•Never run the engine in non ventilat ed or enclosed areas. The exhaust
gases of the engine contain besides the odorless and colourless carbon
monoxide a poisonous gas - hazard! Carbon monoxide can cause uncon-
sciousness and death.
•Never leave your vehicle unattended with the engine running.
Caution
•The starter may only be operated (ignition key position ), 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 oper ating temperature - risk of damaging the
engine!
•Vehicles which are fitted with an exhaust gas catalytic conver ter 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 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 befo re 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 241.
•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 igniti on has been switched on.
