Range of sensors The clearance warning begins at a distance of about 160 cm from the obstacle (area ⇒page 97, fig. 108
). 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.
You should not reverse any further after this signal sounds!
Activating The parking aid is activated automatically when
reverse gear
is engaged and the
ignition is turned on. This is confir
med by a brief acknowledgement signal.
Deactivating The parking aid is deactivated by removing the reverse gear.
WARNING
•
The parking aid is not a substitute fo
r the driver paying proper attention
and it is always the driver's responsibility to take care when parking the vehicle or carrying ou
t similar manoeuvres.
•
You should therefore satisfy yourself, before reversing, that there is no
small obstacle, such as a rock, thin post, trailer drawbar etc., behind your vehicle. Such an obstacle might not be within the range detected by the sensors.
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 ob
stacle close to your vehicle, this indi-
cates 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, more than 30 km/h (20 mph), once it has been set, without you
having to depress the accelerator pedal.
This is only possible within the range wh
ich is permitted by
the power output and
braking power of the engine. The cruise control system makes it possible - particu- larly 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
•
Models fitted with a manual gearbox: Al
ways 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 slide switch and
rocker button in the left lever of the multi-functional switch. – Switch on the cruise control system by sliding the switch
⇒
fig. 109
into the
ON
position.
– After the desired speed has been
reached, briefly press the rocker
button in the
SET
position.
After releasing the rocker button from the
SET
position, the speed you have
stored (above 30 km/hour 20 mph) is ma
intained at a constant speed without
having to depress the accelerator. Yo u c a n
increase
the speed by depressi
ng the accelerator. Releasing the acceler-
ator 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 th
en have to re-store the desired speed.
One can
reduce
the speed in the usual manner. The system is switched off tempo-
rarily by actuating the brake or clutch pedal
⇒page 100.
WARNING
First ensure that it is not too high for the traffic conditions which exist at that moment before resuming the stored speed.Changing a stored speed You can also change the speed of
the vehicle without depressing the
accelerator.Fa s t er –You can
increase
the stored speed without depressing the acceler-
ator, by pressing the rocker button
⇒

in the
RES
position.
– The speed of the vehicle will incr
ease continuously if you hold the
button pressed in the
RES
position. Once the vehicle has reached
the desired speed, release the rocker button. The set speed is then stored in the memory.
Slower –You can
decrease
the stored speed by pressing the rocker button
in the
SET
position.
– Holding down the rocker button pressed in the
SET
position will cause
the speed of the vehicle to reduce
continuously. Once the vehicle has
reached the desired speed, release the rocker button. The set speed is then stored in the memory.
– If you release the rocker button wh
en the vehicle is travelling at a
speed of less than 30 km/h, the speed is not stored, the memory is erased. It is then necessary to again store the speed with the rocker button in the position
SET
after an increase in speed of the vehicle
to more than 30 km/hour.

outer edge in the 9 o'clock and 3 o'clock position. 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 inner
steering wheel edge). In such cases,
injuries to the arms, the hands and the head can occur when the driver airbag is deployed.•
The seat backrests must not be angled too far back when driving other-
wise this will affect proper operation of the seat belts and of the airbag system - risk of injury!•
Ensure that there are no objects in the footwell as any objects may get
behind the pedals during a driving or
braking manoeuvre.
You would then
no longer be able to operate the
clutch, to brake or accelerate.
Correct seated position for the front passenger The front passenger must maintain a distance of at least 25°cm from the dash panel so that the combination of the airbag and the seat belt offers the greatest possible sa
fety when an airbag is deployed.
For the safety of the front passenger and to
reduce the risk of injury in the event of
an accident, we recommend the following setting:•
Adjust the front passenger seat as far as possible to the rear.
•
Adjust the head restraint so that the top edge of the head restraint is at the same
level as the upper part of your head

WARNING
•
The head restraints must always be adjusted to match the body size, in
order to offer an optimal protection for you and your occupants.•
Always keep your feet in the footwell
when the car is being driven - never
put your feet out of the window or on the surfaces of the seats. You will be exposed to increased risk of injury if it becomes necessary to apply the brake or in the event of an accident. If an
airbag is deployed, you may suffer fatal
injuries when adopting an incorrect seated position!•
If the occupants on the rear seats are no
t sitting upright, the risk of injury
is increased due to incorrect routing of the seat belt.
Examples of an incorrect seated position An incorrect seated position can lead to severe injuries or death for the occupants.Seat belts offer their optimum protection on
ly if the webbing of the seat belts is
properly routed. Incorrect seated positio
ns considerably reduce the protective
functions of the seat belts and therefore incr
ease the risk of injury due to an incor-
rect routing of the seat belt. The driver is fully responsible for himself and the occu-pants, in particular for the children. Do
not permit an occupant to adopt an incor-
rect seated position when the car is moving. The following list contains
the examples of seated positions which are dangerous
for the occupants. This list is not comple
te, however we would like you to get inter-
ested in this subject. Therefore, while the car is moving never:•
stand up in the vehicle,
•
stand up on the seats,
•
kneel onto the seats,
•
tilt the seat backrest fully to the back,
•
lean against the dash panel,
•
lie on the rear seats,
•
only sit on the front area of the seat,
•
sit to the side,
•
lean out of the window,
•
put the feet out of the window,
•
put the feet on the dash panel,
•
put the feet on the seat upholstery,
•
occupy the footwell,
•

– Slowly pull the belt webbing at the to
ngue of the lock over your chest
and pelvis
⇒
.
– Insert the tongue of the lock into th
e seat belt buckle belonging to the
seat until it is heard to lock in place.
– Pull on the belt to check that it has also reliably engaged in the lock.Each three-point seat belt is equipped with an inertia reel. This inertia reel offers you complete freedom of movement if the
belt is unreeled slowly. If the brakes are
applied suddenly, the inertia reel will block. It also blocks the belts when the car accelerates, when driving uphill and when cornering. Expectant mothers must also wear the seat belt
⇒
.
WARNING
•
The shoulder part of the seat belt must never run across your neck but
must run approximately over the middl
e of the shoulder and fit snugly
against the chest. The lap part of the
belt must run across the hip and must
never be routed across the stomach. It must always fit snugly
⇒page 110,
fig. 116
. Adjust the belt webbing as required.
•
The lap part of the belt should be positioned as low as possible at the
pelvis of an expectant mother in order to avoid exerting any pressure on the lower abdomen.•
Always ensure that the webbing of the
seat belts is properly routed. Seat
belts which are not correctly adjusted ca
n themselves cause injuries even in
minor accidents.•
A seat belt which is hanging too loose can result in injuries as your body
is moved forward by the kinetic energy produced in an accident and is then suddenly held firm by the belt.•
Only insert the lock tongue into the lo
ck which is the correct one for your
seat. This will affect the protection whic
h the belt offers and increase the risk
of an injury.
Seat belt height adjusterThe seat belt height adjuster makes it possible for you to adapt the routing of the three-point seat belt in
the area of the shoulder to match
your body size. – In order to adjust the height, press
on the upper seat belt deflection
and push it into the desired direction up or down so that the shoulder part of the belt is positioned appr
oximately across the middle of your
shoulder
⇒

.
– Then pull firmly on the belt to ensure
that the seat belt height adjuster
has correctly locked in place.
WARNING
Adjust the height of the belt in such a way that the shoulder part of the belt is positioned approximately across the middle of your shoulder - on no account across your neck.
Note
It is also possible to adapt the routing
of the belt webbing at the front seats by
adjusting the height of the seat.

Driving TipsIntelligent TechnologyElectronic stability programme (ESP)*GeneralGeneral The ESP aids you maintain control of your vehicle in situations in borderline driving situations such as when negotiating a curve too fast. The risk of skidding is reduced and your vehicle thus offers greater driving stability depending on the conditions of the road surface. This occurs at all speeds. The following systems are integrated into the electronic stability programme:•
Electronic Differential Lock (EDL),
•
Traction control system (TCS),
•
Antilock brake system (ABS),
•
Brake Assist.
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 processes additional measurement data which are supplied by highly sensitive sensors: the rotational velocity of the vehi
cle about its vertical axis, the lateral accel-
eration of the vehicle, the brakin
g pressure and the steering angle.
The direction which the driver wishes to ta
ke is determined based on the steering
angle and the speed of the vehicle and is constantly compared with the actual behaviour of the vehicle. If differences exis
t, such as the vehicle beginning to skid,
the ESP will automatically brake the appropriate wheel. The car is stabilised again by the forces which 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 re
ar wheel of a vehicle which tends to under-
steer (tendency to shift out of the curve). This braking control cycle is accompanied by noises. The ESP operates in combination with the ABS
⇒page 135, “Antilock brake system
(ABS)*”. If there is a fault in the ABS system, the ESP also does not operate. The ESP warning light
⇒page 33 lights up in the instrument cluster when there is a
fault on the ESP. Switching off You can switch the ESP off and on again
as you wish, by pressing the button
⇒ fig. 139
. The ESP warning light
⇒page 33 lights up in the instrument cluster
when the ESP is switched off. The ESP should normally always be switched
on. It may be good practice in certain
exceptional cases, such as when you wish
to have wheel slip, to switch off the
system. Examples:

•
when driving with snow chains
•
when driving in deep snow or on a loose surface
•
when it is necessary to rock a vehicle when it has become stuck.
then you should switch on the ESP again.
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 surface and the traffic situation.
This particularly applies when driving on slippery and wet roads. The increased safety offered must not tempt you to take greater risks than other- wise - risk of an accident!
Note
•
All four wheels must be fitted with the same tyres in order to achieve problem-
free operation of the ESP. Differing rolling
circumferences of the tyres can lead to an
undesirable reduction in the engine output.•
Changes to vehicle (e.g. on engine, on the brakes, on chassis or another combi-
nation of tyres and wheels) can influence the function of the ESP
⇒page 179,
“Accessories, changes and replacement of parts”.Electronic Differential Lock (EDL)* The electronic differential lock pr
events an individual wheel from
slipping.Vehicles fitted with ABS*
can be equipped with electron
ic 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 conditio
ns of the road surface are unfavourable.
Operating principle The EDL is activated automatically, 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 greater driving force to the other driven wheel. This control proces
s is also accompanied by noises.
Overheating of the brakes The EDL switches off
automatically 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 driv
en 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 slip-
pery road surfaces, such as ice and sn
ow. The 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 warning light comes on, this ma
y 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 combi-
nation of tyres and wheels) can in
