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.

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

  Selector lever defective! No R gear!
If these symbols light up, there is a fault in the R tronic selector
lever. The indicators on the selector lever will go out or flash. It is no
longer possible to engage reverse gear. If you were using the
gearbox in manual mode, it will switch back to automatic mode.
You can continue to change gear manually. Starting in neutral (N),
pull the paddle lever on the steering wheel to engage first gear.
The gearbox will now remain in manual mode and you can select the
gears using the paddle levers.
You should have the selector lever checked by a qualified workshop
as soon as possible.

Driving 86Parking
If the parking manoeuvre involves shunting backwards and
forwards, the warning sound will be switched off temporarily while
you change gear. The warning beeps will start again as soon as the
vehicle comes closer to an obstacle.
Possible faults
If you hear a long beep when you engage reverse gear (or when you
activate the system using the switch) and the diode in the switch
starts flashing, there is a fault in the system. The long warning beep
is given just once to indicate the fault. If you try activating the
parking aid again, the warning beep will not sound and fault is only
indicated by the flashing diode. This also applies if you switch the
ignition off and then on again: the long warning beep will only
sound the first time you try activating the parking aid. Have the fault
rectified.
If there is a fault in the system there will be no confirming beep
when you activate the parking aid.
To ensure that the acoustic parking aid works properly, the sensors
must be kept clean and free of ice.
WARNING
•
The sensors have blind spots in which obstacles are not regis-
tered. It is particularly important to ensure that there are no small
children or animals near the vehicle when reversing, as the
sensors may not always be able to detect them.
•
The parking aid cannot replace the full concentration of the
driver. The driver is always responsible for safety during parking
and other manoeuvres.Caution
Please note that low obstacles detected by the system may no
longer be registered by the sensors as the car moves closer, so the
system will not give any further warning. Certain kinds of obstacles (such as wire fences, chains, thin painted posts or trailer draw bars,
etc) may not always be detected by the system, so take care not to
damage the vehicle in such cases.
Note
Your vehicle has low ground clearance. To help you prevent damage
to the vehicle, warning beeps will sound when you approach a steep
slope (e.g. in a car park or garage).Cruise control systemApplies to vehicles: with cruise control systemIntroduction
The cruise control system allows you to maintain a
constant speed.The cruise control system allows you to maintain any desired
constant cruising speed at speeds above about 30 km/h. Of course,
this is subject to power output and braking ability of the engine.
This helps to reduce fatigue, especially on long journeys.
The indicator lamp
 in the instrument cluster lights up when the
cruise control system is operating.
The cruise control system is automatically deactivated immediately
by
•
pressing the brake pedal.
•
pressing the clutch pedal.
WARNING
For safety reasons the cruise control system should not be used in
dense traffic or poor road conditions (such as slippery surfaces,
heavy rain, loose grit or gravel) – this could cause an accident.
