If the warning light does not go out after
the engine has started, or comes on when
driving, drive to the nearest specialist garage. The vehicle battery will be discharged in
this case so switch off all non- essential electrical components.
Caution
If the warning light
comes on when driving and in addition the warning light
(cooling system fault) also comes on in di splay, you must then stop the car immedi-
ately and switch the engine off - risk of engine damage!
Engine oil level
Warning light
lights up
If the warning light lights up, the quantity of oil in the engine is probably too low.
Check as soon as possible the oil level or top up page 142, “Replenishing engine oil”
with engine oil.
A peep sounds as an additional warning signal.
The warning light will go out if the bonnet is le ft open for more than 30 seconds. If no
engine oil has been replenished, the warning light will come on again after driving
about 100 km.
Warning light
flashes
A fault on the engine oil level sensor is indicated additionally by an audible signal and
the warning light coming on several times after the ignition has been switched on.
In this case have the engine inspected without delay by a specialist garage.
Fuel reserve
The warning light
comes on, if the fuel level is still below 9 litres.
An audible signal sounds as an additional warning signal.

Automatic wipe/wash for windscreen
– Pull the lever towards the steering wheel into sprung position , the wash system
sprays immediately, the windscreen wiper starts wiping a little later. The wash
system and the windscreen wiper operate simultaneously at a speed of more than
120 km/h.
– Release the lever. The windscreen wash system stops and the wiper continues for another 3 - 4 wiper strokes (depending on the period of spraying of the wind-
screen). At a speed of more than 2 km/h , the wiper wipes once again* 5 seconds
after the last wiper stroke in order to wipe the last drops from the windscreen. This
function can be activated/deacti vated by a specialist garage.Wiping the rear window pane*– Push the lever away from the steering wheel into position - the widescreen
wiper will operate every 6 seconds.Automatic wipe/wash for the rear window pane*– Press the lever from the steering wheel forward into the sprung position , the
wash system sprays immediately, the windscreen wiper starts wiping a little later.
As long as you hold the lever in this position, the wiper operates as well as the wash
system.
– Letting go of the lever will cause the windscreen wash system to stop and the wiper to continue for another 2 - 3 wiper strokes (depending on the period of spraying of
the windscreen). The lever will stay in position after releasing it .Switching windscreen wipers off– Move the lever back into its home position .
After the windscreen wiper switches off each time or the ignition switches off for the
third time, the position of the windscreen wiper changes, this counteracts an early
fatigue of the wiper rubbers.
The windscreen wipers and the wash system only operate if the ignition is switched on
and the bonnet is closed
4). If the intermittent wipe is switched on, the intervals are also controlled depending on
speed.
The rear window will be wiped again if the
front window wipers are on when reverse
gear is selected.
The windscreen washer nozzles are heated* when the ignition is switched on.
Top up with wash liquid page 150.
Winter position
If the windscreen wipers are in rest position, they cannot be folded out from the wind-
screen. For this reason we recommend adjust ing the windscreen wipers in winter so
that they can be folded out from the windscre en easily. You can set this rest position as
follows:
Switch on the windscreen wipers.
Switch off the ignition. The windscreen wipers remain in the position in which they
were when switching off the ignition.
You can also use the service position page 49 as a winter position.
WARNING
Properly maintained windscreen wiper blades are essential for clear visi-
bility and safe driving page 49.
Do not use the windscreen washer sy stem at low temperatures, without
heating the windscreen beforehand. Otherwise the window cleaner could
freeze on the windscreen and re strict the view to the front.
The rain sensor only operates as a su pport. The driver is not released from
the responsibility to set the function of the windscreen wipers manually
depending on the visibility conditions.Caution
In frosty weather, please firs t of all check whether the windscreen wiper blades are not
frozen to the windscreen before switching them on. Switching on windscreen wipers
when the blades are frozen to the windscreen may result in damage both to the blades
and the motor of the windscreen wipers!
4)On vehicles which do not have a contact switch for the bonnet, the windshield wiper and wash
system operates also when the bonnet is opened.

WARNING
Please note that the handbrake must be fully released. A handbrake which
is only partially released can result in the rear brakes overheating which will
have a negative effect on the operation of the brake system - risk of accident! In
addition this can result in premature wear of the rear brake pads.
Never leave children unattended in the vehicle. Children might, for
example, release the handbrake or take the vehicle out of gear. The vehicle
might then move off - risk of accident!Caution
Each time the vehicle is parked, first of all apply the handbrake and then additionally
engage the 1st gear.Rear parking aid*The parking aid provides a warning of obstacles behind the vehicle.The audible parking aid determines the distan ce from the rear bumper to an obstacle
behind the car with the aid of ultrasound sensors. These ultrasound sensors are inte-
grated in the rear bumper.
Range of sensors
The clearance warning begins at a distance of about 160 cm from the obstacle (area
fig. 87 ). The interval between the warning signals becomes shorter as the clearance
is reduced. A continuous tone sounds from
a distance of approx. 30 cm (area ) - danger area.
Do not reverse any further after this signal sounds! If the vehicle is equipped with
a factory-fitted towing device*, the border of the danger area - continuous tone -
extends 5 cm further behind the vehicle. The vehicle can be extended through an
installed detachable towing device.
On vehicles equipped with a factory-fitted radio*, the distance to the obstruction is
shown graphically in the display. On vehicles with a factory-fitted towing device, the
sensors are deactivated when towing a traile r. The driver is informed about this by a
graphic display (vehicle towing a trailer) in the radio* display. The factory-fitted radio*
can be set so that the play function volume decreases when activating the parking aid,
see Owner's Manual radio*. This improves the audibility of the parking aid.
Activating
The parking aid is activated automatically when reverse gear is engaged and the igni-
tion is turned on. This is confirmed by a brief acknowledgement signal.
Deactivating
The parking aid is deactivated by ta king the car out of reverse gear.
WARNING
The parking aid is not a substitute for the driver paying proper attention and
it is always the driver's responsibility to take care when parking the vehicle or
carrying out similar manoeuvres.
You should therefore satisfy yourself, before reversing, that there is no small
obstacle, such as a rock, thin post, trai ler drawbar etc., behind your vehicle.
Such obstacles might not be within the range detected by the sensors.
Under certain circumstances, surfaces of certain objects and types of
clothing cannot reflect the signal of the parking aid. Thus, such objects or
people may not be recognised by the sensors of the parking aid.Note
The parking aid does not operate if you are towing a trailer (applies to models
which feature a factory-fitted towing device*).

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.

Airbag system
98
Function of the side airbags
Risk of injury to the upper part of the body is reduced by fully inflated
side airbags.When the side airbags are deployed, the head airbag* and the belt tensioner are also
automatically deployed on the relevant side fig. 99 .
If an airbag is deployed, the airbag is filled with gas. The airbags inflate in fractions of a
second and at a high speed in order to be able to offer that additional protection in the
event of an accident.
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.
The load of the occupants is cushioned when plunging into the fully inflated airbag and
the risk of injury to the entire upper body (chest, stomach and pelvis) is reduced on the
side facing the door.Important safety information on the side airbag
Correct use of the airbag system cons iderably reduces the risk of injury!
WARNING
It is essential to always switch off the front passenger airbag when attaching
a child safety seat on the front passenger seat where the child is seated with its
back facing in direction of travel (in some countries also when the child is facing
the direction of travel) page 101, “Deactivating an airbag”. If this is not done,
there is a risk of the child suffering seve re or even fatal injuries if the front passenger airbag is deployed. The national
legal provisions in certain countries
require that both the front, side and head airbags be deactivated. When trans-
porting a child on the front passenger seat, please comply with the appropriate
national legal provisions regardin g the use of child safety seats.
Your head should never be positioned in the deployment area of the side
airbag. You might suffer severe injuries in the event of an accident. This applies
in particular to children who are transported without using a suitable child
safety seat page 105, “Child safety and side airbag*”.
If children adopt an incorrect seated position when travelling, they may be
exposed to an increased risk of injury in the event of an accident. This can result
in serious injuries page 103, “What you should know about transporting
children!”.
There must not be any further persons, animals as well as objects posi-
tioned between the occupants and the deployment area of the airbag. No
accessories, such as a can holder, should be attached to the doors.
The airbag control unit operates togeth er with the pressure sensors, which
are attached in the front doors. For this reason no modifications must be
carried out at the doors as well as at the door panels (for example additional
installation of loudspeakers). Resulting damages can have a negative affect on
the operation of the airbag system. All work on the front doors and their panels
must only be carried out by a specialist garage.
In the event of a side collision, the side airbags will not function properly, if
the sensors cannot measure the increasi ng air pressure inside the doors,
because the air can escape through lar ge, non-sealed openings in the door
panel.
Never drive with removed inner door panels.
Never drive, if parts of the inner do or panel have been removed and the
remaining openings have not been properly sealed.
Never drive, if the loudspeakers in the doors have been removed, only if
the loudspeaker openings have been properly sealed.
Always make sure that the openings are covered or filled, if additional
loudspeakers or other equipment part s are installed in the inner door
panels.

Function of the head airbag
The risk of injury to the head and neck area is reduced in the event of a
side collision by fully inflated head airbags.In the case of a side collision the head airbag is deployed together with the relevant
side airbag fig. 101 and the belt tensioner on the side of the car on which the acci-
dent occurs.
If the system is deployed, the airbags are filled with propellant gas and extend over the
entire area of the side wind ow including the door pillar fig. 101 .
The protection offered by the head airbag is thus available simultaneously both to the
front occupants of the car seated on the side on which the accident occurs, as well as
to the rear occupants. Any impact of the head against parts of the interior or objects
outside of the car, is cushioned by the in flated head airbag. The reduction in any
impact to the head and the resultant minimi zing of any movements of the head addi-
tionally reduce the risk of injuries to the neck area. The head airbag also offers addi-
tional protection in the case of an offset impact by covering the front door pillar.
In certain accident situations , the front, side and head airbag are deployed simultane-
ously.
The airbags inflate in fractions of a second an d at a high speed in order to be able to
offer that additional protection in the even t of an accident. A grey white, non harmful
gas is released when airbag is inflated. This is perfectly normal and is not an indication
of a fire in the vehicle.
Important safety information on the head airbag
Correct use of the airbag system cons iderably reduces the risk of injury!
WARNING
It is essential to always switch off the front passenger airbag when attaching
a child safety seat on the front passenger seat where the child is seated with its
back facing in direction of travel (in some countries also when the child is facing
the direction of travel) page 101, “Deactivating an airbag”. If this is not done,
there is a risk of the child suffering seve re or even fatal injuries if the front
passenger airbag is deployed. The national legal provisions in certain countries
require that both the front, side and head airbags be deactivated. When trans-
porting a child on the front passenger seat, please comply with the appropriate
national legal provisions regardin g the use of child safety seats.
There must not be any objects in the deployment area of the head airbags
which might prevent the airbags from inflating properly.
Only hang light items of clothing on the clothes hooks to the vehicle. Never
leave any heavy or sharp-edged objects in the pockets of the items of clothing.
In addition, it is not permitted to use clothes hangers for hanging up items of
clothing.
The airbag control unit operates to gether with the sensors, which are
attached in the front doors. For this reason no modifications must be carried
out at the doors as well as at the door panels (for example additional installa-
tion of loudspeakers). Resulting damage s can have a negative affect on the
operation of the airbag system. All work on the front doors and their panels
must only be carried out by a specialist garage.
There must not be any other persons (e.g. children) or animals between the
sitting occupant and the deployment area of the head airbag. In addition, none
of the occupants should lean their head out of the window when driving, or
extend their arms and hands out of the window.
The sun visors must not be swivelled to the side windows into the deploy-
ment area of the head airbags if any objects, such as ball-point pens etc. are
attached to them. This might result in injuries to the occupants if the head
airbag is deployed.
Installing impermissible accessories in the area of the head airbags may
considerably impair the protection offered by the head airbag in the event of it

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.
