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 78.
WARNING
● Before opening the bonnet and checking the coolant level, observe
the warning information ⇒ page 221.
● 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.

then on again. After this the warning lamp should go out to show that the
system is fully functional.
The warning lamp will light up when the ignition is switched on if the bat-
tery has been disconnected and then reconnected. It should go out again
after driving a short distance if the steering wheel is turned slightly.
For further information on the ESP, see ⇒ page 186.
Alternator
The warning lamp signals a fault in the alternator or in the
vehicle's electrical system.
The warning lamp lights up when the ignition is switched on. It should switch off after the engine has started.
If the warning lamp lights up when you are driving, you can normally
continue as far as the nearest qualified workshop. However, given that the
battery will be running down, any electrical consumption not absolutely vi-
tal should be switched off.
CAUTION
If the coolant warning lamp in the instrument panel lights up as well as
the alternator waning lamp while driving ⇒ page 78, stop the vehicle im-
mediately and switch off the engine. In this case the coolant pump is no
longer working, and there is a risk of engine damage.
Main beam headlights
The indicator lamp
lights up when the main beams are on or when the
headlight flasher is operated. For further information on the main beam headlights, see ⇒
page 122.
Engine management
This warning lamp monitors the engine management sys-
tem for petrol engines.
The warning lamp (Electronic Power Control) lights up while the function
is being checked.
Note
If the warning lamp lights up while the vehicle is moving, this indicates a
fault in the engine management system. The vehicle must be taken immedi-
ately to a qualified workshop to have the engine serviced.
Glow plug system
The indicator lamp lights up while the glow plugs are pre-
heating.
The indicator lamp lights up while the glow plugs are preheating. When
the indicator lamp goes out the engine should be started straight away.
When the engine is warm, or at outside temperatures above +8 °C, the
warning lamp will only light up very briefly.

– Stop the vehicle.
– Switch the engine off.
– Check the fault. Obtain professional assistance if necessary.
BRAKESFault in brake system⇒ page 77
COOLANTCoolant level too low / coolant tempera-
ture too high⇒ page 78

The red symbols are used to indicate a Priority 1 fault (serious malfunction). A red symbol is accompanied by
three warning chimes. The symbols will
keep flashing until the faults are corrected. If several Priority 1 faults are de-
tected at the same time, the symbols are displayed one after the other for
about 2 seconds.
Fault in the brake system
A fault in the brake system should be repaired as soon as
possible.
If the symbol flashes in the display, there is a fault in the brake
system. One of the following messages will appear in the display
together with the symbol:
Stop vehicle, check brake fluid and hydraulic fluid levels
Warning! Fault in brake system (ABS) Take vehicle to workshop
– Stop the vehicle.
– Check the brake fluid level ⇒ page 230.

WARNING
● Before opening the bonnet and checking the brake fluid level, ob-
serve the warning information in ⇒ page 221, 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 226.
– Add more coolant if necessary ⇒ page 227.
– 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 69, 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 224.
– Obtain professional assistance if necessary.
Engine oil level too low
If the engine oil level is too low, add more oil ⇒ page 225.

Air 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. 130 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 158 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.

164Air 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 auxiliary heater will switch on and off auto-
matically 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.

Turn thumbwheel 1
or 2 ⇒ fig. 133 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.

Vehicles with a petrol engine:
–Use the foot brake.
– 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 light will only come on 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.
169
Driving
Stopping the engine
– Turn the ignition key to position 1 ⇒ fig. 137.
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. Handbrake
Handbrake
The handbrake should be applied firmly to prevent the vehi-
cle from accidentally rolling away.
