Technical data Warning lamp

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 35.
If the needle is over to the far right on the dial, this means the
coolant temperature is too high. Stop the vehicle, switch off the
engine and wait for it to cool down. If the warning lamp starts
flashing again after just a short distance, contact a qualified work-
shop.
WARNING
•
Before opening the engine lid and checking the coolant level,
please observe the warning information on ⇒page 155, “Working
on components in the engine compartment”.
•
Never open the engine lid if you can see or hear steam or
coolant escaping from the engine compartment; there is a risk of
being scalded. Wait until you can no longer see or hear escaping
steam or coolant.Caution
•
Additional lights and other accessories in front of the air inlet
reduce the cooling effect of the radiator. At high outside tempera-
tures and high engine loads, there is a risk of the engine over-
heating.
•
The front spoiler also ensures proper distribution of the cooling
air when the vehicle is moving. If the spoiler is damaged this can
reduce the cooling effect, which could cause the engine to overheat.
You should obtain professional assistance.
Fuel gaugeThe gauge only works when the ignition is switched on. When the
needle reaches the reserve zone, the symbol
 lights up in the instrument cluster display ⇒page 36. At this point there are still
about 10 litres of fuel left in the tank. This is your reminder to fill up
soon.
The tank capacity of your vehicle is given in the Technical data
section ⇒page 198.
Caution
Never run the tank completely dry. If there is an irregular fuel supply,
misfiring can occur. This allows unburnt fuel to enter the exhaust
system, which could cause overheating and damage the catalytic
converter.Speedometer with mileage recorder
This instrument indicates the speed of the vehicle and the
distance travelled.The mileage is normally stated in kilometres (km). On some models,
however, the mileage recorder will show miles.
Lower mileage recorder (odometer)
The lower counter records the vehicle's total mileage.

Driver information system 34Yellow symbols are accompanied by one warning chime. The func-
tion indicated should be checked as soon as possible. If several
faults are detected at the same time, the symbols are displayed one
after the other for about 2 seconds at a time.
Driver messages
Additional messages to assist the driver are displayed in
conjunction with the warning lamps and symbols in the
instrument cluster.The display will show the appropriate message if the system detects
a bulb failure ⇒page 37, if the brake pads are worn or you have not
yet selected a gear on a vehicle with R tronic.
The driver can also call up messages in the display for additional
information if a red warning symbol starts flashing.
Calling up driver messages
For example, in the event of an oil pressure malfunction the oil pres-
sure symbol

will appear in the display. If you now press the
adjuster/test button ⇒fig. 31 for at least one second, the following
message will appear in the display:
SWITCH OFF ENGINE AND CHECK OIL LEVEL
The message will disappear from the display after about 5 seconds.
If required, the message can be called up again by briefly pressing
the adjuster/test button.

Technical data
Fault in the brake system

The warning lamp flashes when the handbrake is applied,
or if the brake fluid level is too low or if there is a fault in
the ABS system.If the symbol

flashes in the display when the handbrake
is not applied, there is a fault in the brake system. One of the
following messages will appear in the display together with
the symbol:
Stop vehicle and check brake fluid level
Brake fault ! Drive carefully to nearest workshop
–Stop the vehicle.
– You should obtain professional assistance.
If the ABS fails, the ABS warning lamp
 will light up together with
the brake warning symbol
 ⇒.
Handbrake applied
The warning lamp
 also lights up when the handbrake is applied.
In addition to this, a warning buzzer will sound after driving for
3 seconds at a speed above 5 km/h.
WARNING
•
If the brake fluid level in the reservoir is too low, this could
result in an accident. Do not drive on. You should obtain profes-
sional assistance.
•
If the brake warning lamp lights up together with the ABS
warning lamp, this can mean that the control function of the ABS
is out of action. As a result the rear wheels can lock relatively
easily when braking. This could cause the tail of the vehicle to skid
sideways. Drive carefully to the nearest qualified workshop and
have the fault rectified.
Fault in the cooling system

Faults in the cooling system must be rectified immedi-
ately.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, check coolant level
– Stop the vehicle.
– Switch off the engine.
– Check the coolant level ⇒page 160.
– Add more coolant if necessary ⇒page 160.
– 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
malfunction of the radiator fan.
If the alternator warning lamp lights up as well ⇒page 18, it is
possible that the drive belt has broken.
WARNING
•
If your vehicle should break down for technical reasons, stop it
at a safe distance away from moving traffic, switch off the engine
and turn on the hazard warning lights ⇒page 56, “Hazard
warning lights ”.
•
Never open the engine lid if you can see or hear steam or
coolant escaping from the engine compartment; there is a risk of
being scalded. Wait until you can no longer see or hear escaping
steam or coolant.

Driver information system 38The message disappears after 5 seconds. Press the adjuster/test
button ⇒page 10, fig. 2 briefly if you wish to call up the message
again.
If the display indicates that one of the lights is not working, this can
have a number of causes:•
Bulb failure ⇒page 193.
•
A “blown” fuse ⇒page 190, “Changing fuses”.
•
Defective electrical wiring.
Have the components replaced or the wiring repaired as necessary
by a qualified workshop.
WARNING
•
Bulbs are sensitive to pressure. The glass can break when you
touch the bulb, causing injury.
•
Incorrect handling of the high-voltage element of xenon gas-
discharge bulbs can have potentially fatal consequences.
Brake light failure

If the symbol
 or the text BRAKE LIGHT lights up, check the
following components:
•
Brake light bulbs
•
Wiring connections
•
Brake light switch
Have the components repaired or replaced by a qualified workshop.Note
The brake light switch is only tested during the initial systems check
after starting the engine.
Applies to vehicles: with light sensor/ rain sensorLight sensor/rain sensor

This indicator lamp comes on if the automatic headlights/
automatic wipers are defective.If the
 symbol appears, this means that the light sensor/ rain
sensor is not functioning. For safety reasons, the dipped beam
headlights will then be switched on permanently when the light
switch is set to the AUTO position. However, you can still switch the
lights on and off in the normal way with the light switch. If the rain
sensor is defective, the functions operated via the windscreen wiper
lever will still be available. You should have the light sensor/ rain
sensor checked by a qualified workshop as soon as possible.
Applies to vehicles: with R tronicSelector lever defective
 and


Technical data
Heating and coolingAir conditionerControls
The air conditioner is designed to keep the passenger
compartment at the temperature you find most comfort-
able at all times of the year.Fig. 69 Air conditioner controlsRecommended settings:
– Turn the control ⇒fig. 69 to the right to switch the air
conditioner on.
– Set the temperature to 22 °C (72 °F).
– Press the button ⇒fig. 69.
This setting quickly provides a comfortable temperature inside the
vehicle. If necessary it can be changed to suit individual preferences
or particular circumstances.
The air conditioner provides heating and ventilation and also cools
and dehumidifies the air inside the vehicle.
The air conditioner is fully automatic, and will maintain the desired
temperature at a constant level. To achieve this, the temperature of
the air supplied to the interior, the blower speed (volume of air
delivery) and the air distribution are regulated automatically. The
system also allows for the effect of strong sunlight, so there is no
need for manual adjustment. For these reasons it is advisable to use
the automatic mode for the comfort of all the passengers in virtually
all conditions throughout the year ⇒page 78.
Please note:
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. The air conditioner (compressor) will be switched
off automatically at low outside temperatures (below zero) and will
no longer dehumidify the air inside the vehicle.
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 underneath 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 apply to the defrost setting).
In order to achieve maximum engine power, the air conditioner
compressor is temporarily switched off when pulling away from a
standstill with full throttle.

Heating and cooling 76The compressor also switches off if the coolant temperature is
excessively high, to ensure adequate engine cooling under extreme
loads.
The functions can be set by turning the rotary control and are
switched on and off by briefly pressing the buttons. The LEDs in the
buttons light up when the function is switched on.
Pollution filter
The pollution filter (a particle filter) serves as a barrier against impu-
rities in the outside air, including dust and pollen. The air is also
filtered when the air recirculation mode is activated.
For the air conditioner to work with maximum efficiency, the pollu-
tion filter element must be replaced at the intervals specified in the
Service Schedule.
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.
WARNING
For safety reasons it is important that all the windows are kept
free of ice, snow and condensation. These can cause poor visibility
and lead to an accident. Please familiarise yourself with the oper-
ating controls for the air conditioner, including the demist/defrost
functions for the windows.
Caution
•
If you suspect that the air conditioner is damaged, switch it off
to prevent further damage and have the system checked by a quali-
fied workshop.
•
Repairs to the air conditioning system require specialist knowl-
edge and special tools. For this reason, please contact a qualified
workshop if the system is not working properly.Note
•
Keep the air intake slots in front of the windscreen clear of snow,
ice and leaves to ensure unimpaired heating and cooling, and to
prevent the windows misting over.
•
The air conditioner operates most effectively with the windows
closed. However, if the vehicle has heated up after standing in the
sun for some time, the air inside can be cooled more quickly by
opening the windows for a short time.
Te m p e r a t u r e s e l e c t i o n– Turn the rotary control ⇒page 75, fig. 69 to the
required temperature setting.Turn the rotary control to the left to reduce the temperature. Turn
the rotary control to the right to increase the temperature. There are
several intermediate positions, allowing you to adjust the tempera-
ture as required.
