Coolant temperature gauge
Fig. 38 Engine coolant
temperature gauge
The coolant temperature gauge ⇒ Fig. 38 only works when the ignition is
switched on. In order to avoid engine damage, please read the following
notes for the different temperature ranges.
Cold temperature A
If the needle is still on the left of the dial, this indicates that the engine has
not yet reached operating temperature. Avoid high revs and heavy accelera-
tion and do not make the engine work hard.
Normal temperature B
In normal operations, the needle will settle somewhere in the centre of the
dial once the engine has reached running temperature. The temperature
may also rise when the engine is working hard, especially at high outside8
910
temperatures. This is no cause for concern, provided the warning lamp

does not light up in the instrument panel.
Warning temperature C
If the symbol
 flashes in the display, this means that either the coolant
temperature is too high or the coolant level is too low ⇒ page 81.
WARNING
● Before opening the bonnet and checking the coolant level, observe
the warning information ⇒ page 234.
● Never open the bonnet when steam or coolant is being released from
it. This could lead to burns. Wait until you can no longer see or hear es-
caping steam or coolant.
CAUTION
Accessories in front of the air inlet reduce the cooling effect of the coolant.
At high outside temperatures and high engine loads, there is a risk of the
engine overheating. 

Cockpit
WARNING
● Before opening the bonnet and checking the brake fluid level, ob-
serve the warning information in ⇒ page 234, Work in the engine com-
partment.
● If the brake fluid level in the reservoir is too low, this could result in
an accident. Do not drive on! Obtain technical assistance.
● If the brake warning lamp lights up together with the ABS warning
lamp, this can mean that there is a fault in the ABS control function. As a
result, the rear wheels can lock relatively easily when braking. Under cer-
tain circumstances, the rear of the vehicle could suddenly sway from side
to side, with the subsequent danger of skidding. Drive carefully to the
nearest specialised workshop and have the fault repaired.

Fault in the cooling system 
Faults in the cooling system must be repaired immediately.
If the  symbol flashes in the display, this means that either the
coolant temperature is too high or the coolant level is too low. The
following message will appear in the display together with the
symbol:
Switch off engine and check coolant level
– Stop the vehicle.
– Switch the engine off.
– Check the coolant level ⇒ page 239.
– Add more coolant if necessary ⇒ page 240.
– Wait for the symbol to go out before driving on. –
Obtain professional assistance if necessary.
If the coolant level is correct, the overheating may be caused by a malfunc-
tion of the radiator fan.
If the alternator warning lamp lights up as well ⇒ page 72, it is possible that
the drive belt has broken.
CAUTION
Do not drive on if the symbol  has come on to indicate a fault in the cool-
ing system, otherwise there is a risk of engine damage. 
Engine oil pressure too low 
If the engine oil pressure is too low the fault must be re-
paired immediately.
If the  symbol flashes in the display, the oil pressure is too low.
The following message will appear in the display together with the
symbol:
Switch off engine, check oil level
– Stop the vehicle.
– Switch the engine off.
– Check the engine oil level ⇒ page 237.
– Obtain professional assistance if necessary.
Engine oil level too low
If the engine oil level is too low, add more oil ⇒ page 238.

162Air conditioning
Air conditioning
2C-Climatronic
Description
The air conditioner is designed to automatically keep the
passenger compartment at the temperature you find most
comfortable at all times of the year. Recommended settings:
– Set the temperature to 22°C (71°F).
– Press the AUTO
⇒ Fig. 139 button.
The following setting quickly provides a comfortable temperature inside the
vehicle. We therefore recommend you do not modify the setting unless you
find this temperature uncomfortable or where circumstances require as
such.
The air conditioner provides heating and ventilation and also cools and de-
humidifies the air inside the vehicle.
The air conditioner is fully automatic and will constantly maintain the tem-
perature which has been set. To achieve this, the temperature of the air sup-
plied to the interior, the blower speed (volume of air delivery) and the air
distribution are regulated automatically. The system also takes solar radia-
tion into account and, therefore, no subsequent manual readjustments are
required. Therefore, automatic mode ⇒ page 165 should be used for the
comfort of all the passengers in virtually all conditions throughout the year.
Please note the following points: The humidity of the air is automatically reduced when the system cools the
interior of the vehicle. This helps to prevent condensation on the windows.
If the humidity and temperature outside the vehicle are high,
condensation
can drip off the evaporator in the air cooling system and form a pool under-
neath the vehicle. This is normal and does not indicate a leak.
If the outside temperature is low, the blower normally only switches to a
higher speed once the coolant has warmed up sufficiently (this does not ap-
ply to the defrost setting).
In order to achieve maximum engine power, the air conditioner compressor
is temporarily switched off when pulling away from standstill with full throt-
tle.
The compressor also switches off if the coolant temperature is excessively
high to ensure adequate engine cooling under extreme loads.
Pollution filter
The pollution filter (a combined particulate filter and activated charcoal fil-
ter) 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
element must be replaced at the intervals specified in the Service Plan.
If the vehicle is driven in areas with a high level of air pollution and the filter
is no longer fully effective, it may be necessary to change the filter element
more frequently. 

171
Air conditioning
If the air recirculation mode is on when you switch off the engine, the air
conditioner will automatically switch to fresh air ventilation. 
Auxiliary heater*
Diesel vehicles are fitted with an auxiliary heater 1)
to raise the temperature
of the interior as quickly as possible. At outdoor temperatures below +5°C
and with the engine running, the supplementary heating will switch on and
off automatically depending on the temperature of the coolant.
In order to save fuel, the auxiliary heater can be can be switched off by brief-
ly pressing the 
button on the air conditioner. Seat heating*
The surface and backrest of the front seats can be electrical-
ly heated.
Fig. 142 Detailed view of
the dash panel: Thumb-
wheel controls for seat
heating
Turn thumbwheel 1
or 2 ⇒ Fig. 142 to switch on and adjust the
heating on the left or right front seats.
The heating is switched off when the thumbwheel is set to 0. The tempera-
ture settings range from 1 to 6.
CAUTION
To avoid damaging the heating elements of the seat heating, please do not
kneel on the seat or apply sharp pressure to a single point. 

Driving
– Manual gearbox: Push the clutch pedal all the way down.
– Move the gear lever into neutral (automatic gearbox: selector
lever to P or N) ⇒ 
.
– Turn the ignition key to position 3
without pressing the accel-
erator.
– Release the ignition key as soon as the engine starts (the start-
er motor must not be allowed to run on with the engine).
Vehicles with a diesel engine:
– Use the foot brake.
– Manual gearbox: Push the clutch pedal all the way down. Other-
wise, the engine will not start.
– Move the gear lever into neutral (automatic gearbox: selector
lever to P or N) ⇒ 
.
– Turn the ignition key to position 2
. The pre-heating indicator
light  comes on while the glow plugs are preheating.
– When the indicator light  goes out, turn the ignition key to
position 3
. Do not press the accelerator.
– Having completed the previous action the key can be released
immediately, it will return to position 2
and the engine will
have started.
When starting a very cold engine, it may be a little noisy for the first few sec-
onds until oil pressure has built up in the hydraulic valve compensators.
This is quite normal, and no cause for concern.
If the engine fails to start straight away, stop after 10 seconds and try again
after about half a minute. Glow plug system*
To assist starting at low temperatures,
diesel engines are equipped with a
glow plug preheating system. The preheating time depends on the coolant
temperature and the outside temperature. Start the engine as soon as the
glow plug indicator light  goes out.
When the engine is warm or at outside temperatures above +8°C the glow
plug indicator lamp will only light up for about one second. This means that
the engine can be started immediately.
If the engine will not start...

WARNING
Never run the engine in confined spaces, as the exhaust gases are poi-
sonous.
CAUTION
Avoid high engine speeds, full throttle and extreme load conditions until
the engine has reached its normal operating temperature, otherwise this
can damage the engine.
For the sake of the environment
Do not warm up the engine by running the engine with the vehicle station-
ary. Start immediately. This will help avoid unnecessary exhaust emissions. 
Stopping the engine
– Turn the ignition key to position 1 ⇒ Fig. 146.

176Driving
WARNING
● Never switch the engine off until the vehicle is stationary.
● The brake servo and the power steering system work only when the
engine is running. You need more strength to steer and brake the vehicle
when the engine is switched off. Given that you will be unable to steer
and brake as usual, this could lead to a risk of accidents and injuries.
CAUTION
If the engine has been running under high load for a long time, there is a
risk of heat building up in the engine compartment after the engine has
been switched off; this could cause engine damage. Therefore, you should
let the engine idle for approximately 2 minutes before you switch it off.
Note
After the engine is switched off the radiator fan may run on for up to 10 mi-
nutes, even if the ignition is switched off. It may also start running again af-
ter some time if the coolant temperature rises due to a build-up of heat un-
der the bonnet, or if the engine is already warm and the engine compart-
ment is heated up further by direct sunlight. 
Start-Stop function* Description and operation
The Start-Stop function stops the engine when the vehicle is stop-
ped and starts it automatically when required.
– When the vehicle is stopped, put it in neutral and release the
clutch pedal. The engine will stop. –
When the clutch pedal is pressed, the engine starts again.
– The instrument panel screen displays information about the sta-
tus of the Start-Stop function ⇒ Fig. 148.
Start-Stop function conditions
● The driver seat belt must be buckled.
● The engine hood must be closed.
● The engine must be at operating temperature
● The steering wheel must not be turned more than 270°.
● The vehicle must not be on a steep gradient.
● The vehicle must not be in reverse.
● A trailer must not be connected.
● The temperature of the passenger compartment must be within the con-
venience limits ( ECON
button should not be selected).
● The windscreen de-mist function must be off.
● Otherwise it requires more than 50% of the airflow that the fan can sup-
ply.
● The temperature must not be set to HI or LO.
● The driver door must be closed.
● The diesel particulate filter must not be in regeneration mode, for diesel
engines.
● The battery charge must not be low for the next start.
● The battery temperature must be between –1°C and 60°C.
Start-Stop function interruption
In the following situations, the Start-Stop function will be interrupted and
the engine will automatically start:
● The vehicle starts moving.
● The brake pedal is pressed several times in a row.
● The battery has been discharged excessively. 

177
Driving
● The Start-Stop System is manually deactivated.
● The windscreen de-mist function is turned on.
● The temperature of the passenger compartment exceeds the comfort
limits (button ECON
should not be selected).
● If more than 50% of the airflow that the fan can supply is ordered.
● Temperature setting HI or LO is selected.
● The engine coolant temperature is insufficient.
● The alternator is faulty, for example the V-belt has ruptured.
● If any of the conditions described in the previous section are not fulfil-
led.
WARNING
Never allow the vehicle to move with the engine off for any reason. You
could lose control of your vehicle. This could cause an accident and seri-
ous injury.
● Power steering does not work when the engine is not running. That is
why it is much more difficult to turn the steering wheel.
● Disconnect the Start-Stop system when driving through water (ford-
ing streams, etc.).
Note
● For vehicles with the Start-Stop function and a manual gearbox, when
the engine is started, the clutch must be pressed.
● When the conditions for the Start-Stop function are not fulfilled, the in-
strument panel displays the Start-Stop indicator dimmed.
● If the steering wheel is turned more than 270°, Stop will not function;
however, the angle of steering wheel turn does not affect starting the vehi-
cle. Activating and deactivating the Start-Stop function
