WARNING
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 inju-
ries or major vehicle damage.
The engine compartment of your car is a hazardous area. There is a risk of
injuries, scalding, accidents and fire wh en working in the engine compartment,
e.g. inspecting and replenishing oil and other fluids. It is also essential to
observe all warnings page 140, “Working in the engine compartment”.Note
The arrangement of the indicator lights depends 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 symbol s (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.
Switching off the hazard warning light system is switched on will cause all of the turn
signal lights as well as both indicator lights to flash.
Further information about the turn signal system page 44.
Fog lights*
The warning light
comes on when the fog lights are operating page 43.
Main beam
The indicator light
comes on when the main beam is selected or also when the
headlight flasher is operated.

The warning light
comes on when low beam is selected page 42.
Rear fog light
The warning light
comes on when the rear fog lights are operating page 43.
Cruise control system*
The warning light
lights up, when operating the speed regulating system.
Bulb failure
The warning light
comes on if a bulb is faulty:
up to 2 seconds after the ignition is switched on,
when switching on the defective light bulb.
The rear side lights and the licence plate li ghting require several light bulbs. The indi-
cator light
only lights up if all light bulbs of the licence plate lighting or the parking
light (in one rear light unit) are defective. Check regularly the function of the light
bulbs.
Airbag system
Monitoring the airbag system
The warning light
comes on for a few seconds when the ignition is switched on.
There is a fault in the system if the warning light does not go out or flashes while driving
. This also applies if the warning light does not come on when the ignition is
switched on.
The functionality of the airbag system is also monitored electronically when one airbag
has been switched off. Front, side and head airbags or belt tensioner which have been switched off
using the vehicle
system tester:
The warning light
lights up for 4 seconds after switching on the ignition and then
flashes again for 12 seconds in intervals of 2 seconds.
Front passenger airbags sw itched off using the switch for front passenger
airbags* in storage compartmen t on the front passenger side:
the warning light
comes on for 4 seconds after the ignition has been switched
on,
switching off the airbag is indicated in the middle of the dash panel by the lighting
up of the indicator light
(airbag switched off) page 101.
WARNING
Have the airbag system checked immediat ely by a specialist garage if a fault
exists. Otherwise, there is a risk of the airbag not being activated in the event of
an accident.Control system for exhaust
The warning light
comes on after the ignition has been switched on.
If the warning light does not go out after starti ng the engine or it lights up when driving,
a fault exists in an exhaust relevant co mponent. The engine management system
selects an emergency programme which enables you to drive to the nearest specialist
garage by adopting a ge ntle style of driving.
Electromechanical power steering
The warning light
comes on for a few seconds when the ignition is switched on.
If the warning light after switching on the ignition or when driving lights up continu-
ously, a fault exists in the electromechanical power steering.
If the yellow warning light lights up
, this indicates a partial failure of the power
steering and the steering forces can be greater.
If the red warning light lights up
, this indicates a complete failure of the power
steering and the steering assist has failed (significantly higher steering forces).

Switching on side lights– Turn the light switch into position
.
Switching on the low beam and main beam– Turn the light switch into position
.
– Press the main beam lever forward in order to switch on the main beam page 44, fig. 38 .
Switching off lights (except daylight driving lights)– Turn the light switch into position°0.
Low beam comes on only if the ignition is switched on. After switching off the ignition,
the low beam is switched off automatica lly and only the side lights come on.
On models fitted with right-hand steering the position of certain switches differs
from that shown in fig. 34 . The symbols which mark the switch positions are iden-
tical, however.
WARNING
Never drive with side lights on - risk of accident! The side lights are not bright
enough to light up the road sufficiently in front of you or to be seen by other
oncoming traffic. In this case, always switch on the low beam when it is dark or
if visibility is poor.
Note
An audible warning will sound if you wi thdraw the ignition key and open the
driver's door when the vehicle lights are still on.
The acoustic warning signal is switched off over the door contact when the driver's
door is closed (ignition off). The vehicle can be parked with the side lights on.
If the car is parked for a lengthy period, we recommend switching off all lights, or
leaving only the parking lights switched on.
The switching on of the described lights should only be undertaken in accordance
with the legal requirements.
If a fault occurs in the light switch , the low beam comes on automatically
In the event of cool or humid weather conditions, the headlights can be misted up
from inside.
The temperature difference between interior and external area of the headlight
lenses is decisive.
When the driving lights are switched on, the light outlet surfaces are free from
mist after a short period. The headlight lens es can possibly mist up at the border
areas.
It also concerns reverse light and turn signal lights.
This mist has no influence on th e life of the lighting system.
“DAY LIGHT”* Switching on daylight driving lights– Switch on the ignition without turning the light switch out of the position 0.

Starting-off and Driving
78
You should not switch on any major elec trical components during the heating
period. Otherwise the ve hicle battery will be drained unnecessarily.
- start engine
Applies to all models:
Position
To lock the steering , with the ignition key withdrawn, turn the steering wheel until the
steering locking pin is heard to engage. You should always lock the steering as a general
rule if you leave your vehicle. This acts as a deterrent against possible theft of your
vehicle .
Position
Move the steering wheel back and forward a little if the ignition key cannot, or cannot
easily be turned into this position, in order to release the steering lock.
Position
The engine is started in this position. At the same time any switched on low beam or
main beam or other electrical components with major electrical consumers are briefly
switched off. The ignition key moves back into position after being released.
The ignition key must be turned back into position each time before starting the
engine again. The starter repeat lock in th e ignition lock prevents the starter being
engaged when the engine is r unning and thus getting damaged.
WARNING
When driving, the ignition key must always be in the position (ignition
switched on) without the engine running. This position is indicated by the
warning lights coming on. If this is not the case, it could result in unexpected
locking of the steering wh eel - risk of accident!
Do not withdraw the ignition key from the lock until the vehicle has come to
a stop. The steering lock can engage immediately - risk of accident!
Always withdraw the ignition key if you are going to leave the vehicle, even
for a short time. This is particularly important if children are left in the vehicle.
Children might otherwise st art the engine or switch on electrical equipment
(e.g. power windows) - risk of accident or injury!
Starting the engineGeneral
You can only start the engine only using an original ignition key.
Place the gearshift lever into neutral and put on the handbrake firmly before
starting the engine.
Before starting, it is necessary to depres s the clutch pedal and to keep it pressed
down until the engine starts. If you try and start the engine without pressing the clutch
pedal, the engine will not start. A message in the information display of the instrument
cluster will also appear indicate th e need to press the clutch pedal.
Let go of the ignition key as soon as the engine starts otherwise you may damage
the starter.
The engine running noises may 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 normal 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 165.
It is only possible to tow-start vehicles fi tted with a manual gearbox. The tow-starting
distance must not be more than 50 metres. Observe the following
guidelines page 167, “Tow-starting and towing vehicle”.
WARNING
Never run the engine in non ventilated or enclosed areas. The exhaust gases
of the engine contain besides the odou rless and colourless carbon monoxide a
poisonous gas - hazard! Carbon mono xide can cause unconsciousness and
death.
Never leave your vehicle unattended with the engine running.Caution
The starter may only be operated (ignitio n key position ), if the engine is not
running. If the starter is imme diately operated after switchin g off the engine, the starter
or the engine can be damaged.
