Starting-off and DrivingSetting steering wheel positionFig. 83 Adjustable steering wheel: Lever below steering columnYou can set the height and the forward/back position of the steering wheel to the
desired position.
– Adjust the driver seat page 11.
– Pull the lever below the steering column down fig. 83 - left. Observe the guide-
lines .
– Set the steering wheel to the desired position (concerning height and forward/back position).
– Push the lever upwards as far as the stop.
WARNING
You must not adjust the steering wheel when the vehicle is moving!
The driver must maintain a distance of at least 25 cm to the steering wheel
fig. 83 - right. Not maintaining this minimum distance will mean that the
airbag system will not be able to properly protect you - hazard!
For safety reasons the lever must always be firmly pushed up to avoid the
steering wheel altering its po sition unintentionally when driving - risk of acci-
dent!
If you adjust the steering wheel furthe r towards the head, you will reduce
the protection offered by the driver airbag in the event of an accident. Make
sure the steering wheel is aligned to the chest.
When driving, hold the steering wheel with both hands firmly on the outer
edge in the 9 o'clock and 3 o'clock po sition. Never hold the steering wheel
firmly in the 12 o'clock position or in another way (e.g. in the middle of the
steering wheel or at the inne r steering wheel edge). In such cases, injuries to the
arms, the hands and the head can occur when the driver airbag is deployed.

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To lock the steering , with the ignition key withdrawn, turn the steering wheel until the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.

Technical Data
Avoid high engine revolutions, full throttle and high engine loads as long as the
engine has not yet reached its normal oper ating temperature - risk of damaging the
engine!
Vehicles which are fitted with an exhaust gas catalytic converter should not be tow-
started over a distance of more than 50 metres.For the sake of the environment
Never warm up the engine when the vehicle is standing. Drive off right away. Through
this the engine reaches its operating temperature more rapidly and the pollutant emis-
sions are lower.Petrol enginesThese engines are fitted with a starter system which selects the correct fuel-air mixture
for every external air temperature.
Do not operate accelerator before and when starting engine.
Interrupt the attempt at starting after 10 seconds if the engine does not start right
away and wait for about 30 seconds before repeating the attempt.
It is possible that the fuse on the electric al fuel pump is defect if the engine still
does not start. Check the fuse and replace it if necessary page 169.
Contact the nearest specialist garage to obtain professional assistance.
It may be necessary, if the engine is very hot, to slightly depress the accelerator after
the engine has started.
Diesel enginesGlow plug system
Diesel engines are equipped with a glow plug system, the preglow period being
controlled automatically in line with the coolant temperature and outside tempera-
ture.
The preglow indicator light
comes on after the ignition has been switched on.
You should not switch on any major electrical components during the heating
period otherwise the vehicle battery will be drained unnecessarily.
You should start the engine immediately after the glow plug warning light
has
gone out.
The glow plug warning light will come on for about one second if the engine is at a
normal operating temperature or if the outside temperature is above +5 °C. This
means that you can start the engine right away.
Interrupt the attempt at starting after 10 seconds if the engine does not start right
away and wait for about 30 seconds before repeating the attempt.
It is possible that the fuse on the diesel preglow system is defect if the engine still
does not start. Check the fuse and replace it if necessary page 169.
Contact the nearest specialist garage to obtain professional assistance.
Starting the engine after the fuel tank has run dry
It may take longer than normal to start the engine after refuelling if the fuel tank has
run completely dry - up to one minute. This is because the fuel system must first of all
be filled while the attempting to start the engine.
Switching off the engine– The engine can be switched off by tu rning the ignition key into position
page 77, fig. 84 .
WARNING
Never switch off the engine before the vehicle is stationary - risk of accident!
The brake booster only operates when the engine is running. Greater phys-
ical effort for braking is required when en gine is switched off. Because if you do
not stop as normal, this can cause an accident and severe injuries.Caution
you should not switch the engine off right away at the end of your journey after the
engine has been operated for a lengthy period at high loads but should be allowed it
to run at idling speed for about 2 minutes. This prevents any accumulation of heat
when the engine is switched off.

80Note
The radiator fan may continue running fo r a further 10 minutes or so after the
engine and the ignition have been switched off. The coolant fan may, however, also
switch on again after some time if the co olant temperature rises because of an accu-
mulation of heat in the engine or if the engine is warm and the engine compartment is
additionally heated by strong sunlight.
This is why particular care is required when carrying out any work in the engine
compartment page 140, “Working in the engine compartment”.
ShiftingShift into reverse only when the vehicle is stationary. Depress the clutch pedal and hold
it fully depressed. Wait a moment before en gaging reverse gear in order to avoid any
shift noises.
The reversing lights will come on once reverse gear is engaged, provided the ignition is
on.
WARNING
Never engage the reverse gear when driving - risk of accident!
Note
One should not lay the hand on the shift lever while driving the vehicle. The pres-
sure of the hand will be transferred to the gearshift forks in the gearbox. This can, over
a period of time, lead to earl y wear of the gearshift forks.
Depress the clutch pedal fully when changi ng gears, in order to avoid unnecessary
wear and damage.
HandbrakeApplying the handbrake– Pull the handbrake lever up fully.Releasing the handbrake– Pull the handbrake lever up slightly and at the same time press in the locking
button fig. 86 .
– Hold the button pressed and push the handbrake lever down fully .
The handbrake warning light
lights up when the handbrak e is applied, provided the
ignition is on.
A warning signal sounds if you have inadvertently driven off with the handbrake
applied.
The handbrake warning is activated if you drive at a speed of more than 6 km/h for
more than 3 seconds.

If a warning signal sounds for about 3 seconds after switching the ignition on and
engaging reverse gear, and there is no obstac le close to your vehicle, this indicates a
system fault. Have the fault rectified by a specialist workshop.
The sensors must be kept clean and free of ice to enable the parking aid to operate
properly.
Cruise control system (CCS)*IntroductionThe cruise control system (CCS) maintains a constant speed, above approx. 30 km/h
(20 mph), once it has been set, without yo u having to depress the accelerator pedal.
This is only possible to the extent permit ted by the power output and braking power of
the engine. The cruise control system makes it possible - particularly on long journeys
- for you to rest your “accelerator foot”.
WARNING
The cruise control system must not, for safety reasons, be used in dense
traffic or on unfavourable road surfaces (such as icy roads, slippery roads or
loose chippings) - risk of accident!
In order to prevent unintentional use of the cruise control system, always
switch off the system after use.Note
Always depress the clutch pedal if you switch on the cruise control system when
the gearbox is in Neutral. Otherwise the engine can rev up unintentionally.
The cruise control system is not able to maintain a constant speed when driving on
steep downhill sections. The weight of the vehicle increases the speed at which it
travels. One should shift down in good time to a lower gear or slow the vehicle down
by applying the foot brake.
Storing a speedThe cruise control system is operated by means of the switch and rocker button
in the left lever of the multi-functional switch.
– Press the switch fig. 88 into the position ON.
– After the desired speed has been reached, press the rocker button into the SET
position.
After you have released the rocker button out of the position SET, the speed you
have just stored is maintained at a consta nt speed without having to depress the accel-
erator.
You can increase the speed by depressing the acce lerator. Releasing the accelerator
will cause the speed to drop again to the set speed.
This does not apply, however, if you drive at a speed which is more than 10 km/h higher
than the set speed for a period of longer than 5 minutes. The stored speed will be
cancelled in the memory. You have to re-store the desired speed.
One can reduce the speed in the usual manner. The system is switched off temporarily
by actuating the brake or clutch pedal page 83.
WARNING
First ensure that it is not too high for the traffic conditions which exist at that
moment before resuming the stored speed.

Technical Data
When are the airbags deployed?The airbag system is designed in such a wa y that the driver and front passenger airbag
are deployed in the event of a violent frontal collision.
In the case of a violent side collision , the side airbag* on the side of the vehicle at
which the collision occurs, is deployed to gether with the relevant head airbag*.
In special accident scenarios, the front as well as the relevant side and head airbags
may be deployed together.
The airbags are not deployed in the case of minor frontal and side collisions, in the
case of rear-end collisi ons and vehicle rollover.
Deployment factors
It is not possible to state globally which deployment conditions apply to the airbag
system in every situation as the circumstances which exist in the case of accidents vary
greatly. An important role in this case is played by factors such as the type of object
against which the vehicle impacts (hard, soft ), the angle of impact, the relative speed
during the accident etc.
A decisive factor for the deployment of the airbags is the deceleration which occurs
during a collision. The control unit analyses the nature of the collision and activates the
relevant restraint system. If the vehicle deceleration which occurs and is measured
during the collision remains below the prescribed reference values specified in the
control unit, the airbags are no t deployed although the vehicle may well suffer severe
damage to the bodywork as a consequence of the accident.
The airbags are not deployed if:
ignition off,
a minor frontal collision,
a minor side collision,
a rear-end collision,
Rollover of the vehicle.Note
A grey white, non harmful gas is released when airbag is inflated. This is perfectly
normal and is not an indicati on of a fire in the vehicle.
In the event of an accident in which the airbags are deployed:
The interior lighting comes on (if the switch for the interior light is in the door
contact position),
The hazard warning light is switched on,
All the doors are unlocked,
the fuel supply to the engine is interrupted.
Front airbagsDescription of the front airbags
The airbag system is not a su bstitute for the seat belt!Fig. 95 Driver airbag in the steering whee l/front passenger airbag in the dash panelThe front airbag for the driver is housed in the steering wheel fig. 95 - left. The front
airbag for the front passenger* is housed in the dash panel above the storage compart-
ment fig. 95 - right. The installation positions are each marked with the “AIRBAG”
logo.
The front airbag system is complementary to the three-point seat belts and offers addi-
tional protection for the head and chest area of the driver and passenger in the event
of a frontal collision. page 96
The airbag is not a substitute for the seat belt, but is part of the complete passive
vehicle safety concept. Please note that an airbag can only offer you optimal
protection in combination with a seat belt which is fastened .

Technical Data
Driving TipsIntelligent TechnologyElectronic stability programme (ESP)*GeneralThe ESP aids you in maintaining control of your vehicle in situations in which the
vehicle is driving at its dynamic limits, such as entering a curve fast. The risk of skidding
is reduced and your vehicle thus offers greater driving stability depending on the
conditions of the road surface. The system operates at all speeds.
The following systems are integrated into the electronic stability programme:
Electronic Differential Lock (EDL),
Traction control system (TCS),
active driver-steering recommendation (DSR),
Antilock brake system (ABS),
Brake Assist,
Uphill-Start off-Assist.
The ESP system cannot be switched off, only the TCS system can be switched off by
pressing the button fig. 111 , the warning light
lights up. Operating principle
The ESP switches on automatically when the engine is started and then conducts a
self-test. The ESP control unit processes data from the individual systems. It also proc-
esses additional measurement data which are supplied by highly sensitive sensors: the
rotational velocity of the vehicle about its ve
rtical axis, the lateral acceleration of the
vehicle, the braking pressure and the steering angle.
The direction which the driver wishes to take is determined based on the steering
angle and the speed of the vehicle and is co nstantly compared with the actual behav-
iour of the vehicle. If differences exist, such as the vehi cle beginning to skid, the ESP will
automatically brake the appropriate wheel.
The car is stabilised again by the forces wh ich take effect when the wheel is braked.
Intervention into the brake system takes place primarily on the outer front wheel of a
vehicle which tends to oversteer (tendency for the rear of the vehicle to break away)
while occurs this is on the inner rear wh eel of a vehicle which tends to understeer
(tendency to shift out of the curve). This braking control cycle is accompanied by
noises.
During an intervention of the system, the warning light
flashes quickly in the instru-
ment cluster page 26.
The ESP operates in combination with the ABS page 115, “Antilock brake system
(ABS)”. If there is a fault in the ABS system, the ESP also does not operate.
The ESP warning light lights up in the instrument cluster when there is a fault on the
ESP
page 26.WARNING
It is also not possible for the ESP to overcome the physical limits of the vehicle.
Even if a vehicle fitted with ESP you should still always adapt your style of
driving to the condition of the road surfac e and the traffic situation. This partic-
ularly applies when driving on slippery and wet roads. The increased safety

offered must not tempt you to take greater risks than otherwise - risk of an acci-
dent!
Note
All four wheels must be fitted with the same tyres in order to achieve problem-free
operation of the ESP. Differing rolling circum ferences of the tyres can lead to an unde-
sirable reduction in the engine output.
Changes to vehicle (e.g. on engine, on th e brakes, on chassis or another combina-
tion of tyres and wheels) can influence the function of the ESP page 157, “Accesso-
ries, changing and replacing parts”.
Electronic Differential Lock (EDL)*
The electronic differential lock prev ents an individual wheel from slip-
ping.Models fitted with ESP ar e equipped with electronic differential lock (EDL).
General
The EDL makes it much easier, and sometimes at all possible, to start off, accelerate
and climb a steep hill when the conditions of the road surface are unfavourable.
Operating principle
The EDL is activated automaticall y, that is without any action on the part of the driver.
It monitors the speeds of the driven wheels with the aid of the ABS sensors. Should
only one drive wheel begin spinning on a slippery surface there will be an appreciable
difference in the speed of the driven wheels. The EDL function brakes the slipping
wheel and the differential transmits a greate r driving force to the other driven wheel.
This control process is also accompanied by noises.
Overheating of the brakes
The EDL switches off automatica lly if unusually severe stresses exist in order to avoid
excessive heat generation in the disc brake on the wheel which is being braked. The
vehicle can continue to be driven and has the same characteristics as a vehicle not
fitted with EDL. The EDL switches on again automatically
as soon as the brake has cooled down.
WARNING
Carefully depress the accelerator when accelerating on uniformly slippery
road surfaces, such as ice and snow. Th e driven wheels might still spin despite
the EDL and affect the stability of the vehicle - risk of an accident!
You should always adapt your style of driving to the condition of road
surface and to the traffic situation even when your vehicle is fitted with EDL.
The increased safety offered must not tempt you to take greater risks than
otherwise - risk of an accident!Note
If the ABS or ESP warning light comes on, this may also indicate a fault in the EDL.
Please have the vehicle inspected as soon as possible by a specialist garage.
Changes to vehicle (e.g. on engine, on the brakes, on chassis or another combina-
tion of tyres and wheels) can influence the function of the EDL page 157, “Accesso-
ries, changing and replacing parts”.
Traction control system (TCS)
The traction control system prevents the driven wheels from spinning
when accelerating.
