The handbrake warning light
lights up when the handbrak
e is applied, provided the
ignition is on. A warning signal sounds and the following text
appears in the display* if you have inad-
vertently driven off with the handbrake applied:
Handbrake on
The handbrake warning is acti
vated if you drive at a speed of more than 6 km/h for
more than 3 seconds.
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. The children might, for
example, release the handbrake or take
the vehicle out of gear. The vehicle
might then move off - risk of accident!
Caution
After the car has come to a stop, always firs
t of all apply the handbrake firmly before
then additionally engaging a gear (manual gearbox) or moving the selector lever into position
P (automatic gearbox).
Rear parking aid*The parking aid provides a warning
of obstacles behind the vehicle.
The audible parking aid determines the di
stance between the rear bumper and an
obstacle located behind the ve
hicle with the aid of ultras
ound sensors. The tones of
the parking aid can be adapted in th
e menu of the information display*
⇒page 27.
The sensors are integrated in the rear bumper. Range of sensors The clearance warning begins at a distance
of about 160 cm from the obstacle (area
⇒ fig. 117
). The interval between the warning signals becomes shorter as the clear-
ance 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!
If the vehicle is
equipped with a factory-fitted
towing device*, the border of the danger area starts,
continuous tone, 5 cm furt
her behind the vehicle. Th
e vehicle can be extended
through an installed deta
chable towing device.
On vehicles equipped with a factory-fitted
radio* or navigation system*, 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 trailer. The driver is informed about this by a graphic display (vehicle towing
a trailer) in the radio* or the navigation*
display. The radio* or navigation system*, which is factory-fitted, can be set so that the play function volume decreases when acti

Driving TipsIntelligent TechnologyElectronic stability programme (ESP)*GeneralGeneral The 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, the
TCS system can only be switched off by
pressing the button
⇒fig. 154
, then the ESP warning light flashes slowly
.
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 whic
h 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 35.
The ESP operates in combination with the ABS
⇒page 167, “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 inst
rument cluster when there is a fault on the
ESP
⇒page 35.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 221, “Accesso-
ries, changes and replacement of 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.
EDL Off-road* After switching on the Off-road mode
⇒page 170, EDL Off-road is activated.
EDL Off-road is matched in such a way that it assists the traction of the vehicle when driving on an unfirm ground. EDL is activated earlier in the Off-road mode than in the normal mode. The brake pres- sure builts up more quickly on the slipping
wheel, on one axle, as well as diagonally.
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

ries, changes and replacement of parts”.

Technical Data
Traction control system (TCS) The traction control system prevents
the driven wheels from spinning
when accelerating.General The TCS makes it much easier, and sometimes at
all possible, to start off, accelerate and
climb a steep hill when th
e conditions of the road
surface are unfavourable.
Operating principle The TCS switches on automatically when th
e engine is started and then conducts a
self-test. The system monitors the speeds of the driven wheels with the aid of the ABS sensors. If the wheels are spinning, the force transmitted to the road surface is auto- matically adapted by reducing the engine speed. The system operates at all speeds. The TCS operates in combination with the ABS
⇒page 167, “Antilock brake system
(ABS)”. The TCS will not function if a fault exists in the ABS system. The TCS warning light lights up in the instru
ment cluster when there is a fault on the
TCS
⇒page 34.
During an intervention of the system, the TCS warning light
flashes quickly in the
instrument cluster
⇒page 34.
Switching off You can switch the TCS off and on again as yo
u wish. On vehicles fitted with ABS, you
can switch off the TCS by pressing the button
⇒fig. 155
, on vehicles fi
tted with ESP*,
you can switch off the TCS wi
th the aid of the button
⇒page 163, fig. 154
. The TCS
warning light
flashes slowly in the instrument cluster if the system is switched off
⇒ page 34. The TCS 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 TCS again. TCS Off-road* After switching on the Off-road mode
⇒page 170, TCS Off-road is activated.
TCS Off-road provides a more effective a
cceleration of the vehicle on an unfirm
ground, as it allows higher traction be
tween the slipping wheels and the ground.
The system operates when starting off or at low speeds.
WARNING
You should always adjust your style of driving to the conditions of the road surface and the traffic situation. The increased safety offered must not tempt you to take greater risks than otherwise - risk of an accident!

WARNING
Contact your specialist
garage if the power steering is defective.
Tyre inflation pressu
re-control system*
The tyre inflation pressure-control system compares with the aid of the ABS sensors the speed and also the rolling circumference of the individual wheels. If the rolling circumference of a wheel is changed, the warning light
lights up in the instrument
cluster
⇒page 35 and an audible signal sounds.
The rolling circumference of the tyre
can change if:•
the tyre inflation pressure is too low,
•
the structure of the tyre is damaged,
•
the vehicle is loaded on one side,
•
the wheels of an axle are loaded heavily (e.g. when towing a trailer or when driving
uphill or downhill),•
snow chains are mounted,
•
the temporary spare wheel is mounted,
•
one wheel per axle was changed.
Basic setting of tyre inflation pressure-control system After changing the tyre inflation pressures or after changing one or several wheels, the position of a wheel on the vehicle (e.g. ex
changing the wheels between the axles) or
when the warning light lights up while drivin
g, a basic setting of the system must be
carried out as follows.•
Inflate all tyres to the specified inflation pressure
⇒page 215.
•
Switch on the ignition.
•
Press button
⇒fig. 156
for more than 2 seconds. While pressing the button,
the warning light
lights up. At the same time the memory of the system is erased
and the new calibration is started, which is confirmed with an audible signal and then the warning light
goes out.
•
If the warning light
does not go out after the basic
setting, there is a fault in the
system. Have the vehicle inspected by your nearest specialist garage. Warning light
lights up
If the tyre inflation pressure of at least one
wheel is insufficiently inflated in comparison
to the stored basic va
lue, the warning light
⇒
lights up.
Warning light
flashes
If the warning light flashes, there is a system fault. Have the vehicle inspected by your nearest specialist garage.
WARNING
•
When the warning light
lights up, immediately reduce the speed and
avoid sudden steering and brake manoeuvr
es. Please stop the vehicle without
delay at the nearest possible stop and in
spect the tyres and their inflation pres-
sures.•
The driver is responsible for the correc
t tyre inflation pressures. For this
reason, the tyre inflation pressu
res must be checked regularly.
•
Under certain circumstances (e.g. sporty style of driving, wintry or unpaved
roads) the warning light
can be delayed or does not light up at all.
•
The tyre inflation pressure-control system does not take away the respon-
sability from the driver for the
correct tyre inflation pressure.
