Do not place any footmats or other additional floor coverings in the area of
the pedals in order to ensure that all the pedals can be fully depressed and are able to return unobstructed to their initial position - risk of accident!•
There must be no objects on the floor
which could roll under the pedals. You
would then no longer be able to apply
the brakes, operate the clutch or acceler-
ator - risk of accident!Luggage compartmentLoading the luggage compartmentPlease observe the following in the interest of having good handling characteristics of your vehicle: – Distribute the items of luggage as evenly as possible. – Place heavy objects as far forward as possible.– Attach the items of luggage to the lashing eyes or the fixing net*
⇒page 79.
In the event of an accident, there is such a
high kinetic energy wh
ich is produced by
small and light objects that they can cause se
vere injuries. The magnitude of the kinetic
energy depends on the speed at which the vehi
cle is travelling and on the weight of the
object. The speed at which the vehicle is travelling is in this case the more significant factor. Example: In the event of a frontal collision at a speed of 50 km/h, an unsecured object with a weight of 4.5 kg produces an ener
gy, which corresponds to 20 times its own
weight. This means that it results in a weight of approx. 90 kg. You can imagine the inju- ries that can occur, if this “bullet” is fl
ying through the interior
compartment and hits
an occupant.
WARNING
•
Store the objects in the luggage compartment and attach them to the
lashing eyes, e.g. with the fixing nets.
•
Loose objects in the passenger compartment can be thrown forward during
a sudden manoeuvre or in case of an a
ccident and can injure the occupants or
other oncoming traffic. This risk is still increased, if the objects which are flying around are hit by a deployed airbag. In this case, the objects which are thrown back can injure the occupants - hazard.•
Please note that the handling properti
es of your vehicle may be affected
when transporting heavy objects as a result
of the displacement of the centre of
gravity. The speed and style of driv
ing must be adjusted accordingly.
•
The items carried in the luggage compartment should be stowed in such a
way that no objects are able to slip forward if there are any sudden driving or braking manoeuvres undertaken - risk of injury!•
Never drive with the boot lid fully open
ed or slightly ajar otherwise exhaust
gases may get into the interior of the vehicle - risk of poisoning!•
On no account exceed the permissible
axle loads and the permissible gross
weight of the vehicle - risk of accident!•
Never transport occupants in the luggage compartment!Caution
Please ensure that the heating elements of the rear window heater are not damaged as a result of objects sliding in this area.
Note
Tyre pressure must be adjusted to the load

button
⇒fig. 116
.
– 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 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
vating the parking ai
d, see Owner's Manual

How are seat belts correctly fastened?Fastening three-point seat belts Fasten your seat be
lt before starting!
Fig. 134 Routing of belt webbing for an expect
ant mother / routing of belt webbing over the
shoulders and the lap belt– Correctly adjust the front seat and the head
restraint before fastening your seat belt
⇒ page 72.
– Slowly pull the belt webbing at the tongue
of the lock over your chest and pelvis
⇒
.
– Insert the tongue of the lock into the 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 middle of the shoulder and fit snugly against the
chest. The lap part of the belt must r
un across the hip and must never be routed
across the stomach. It must always fit snugly
⇒fig. 134
on the right. Adjust the
belt webbing as required.•
The lap part of the belt should be posi
tioned as low as possible at the pelvis
of an expectant mother in order to avoid exerting any pressure on the lower abdomen
⇒fig. 134
on the left.
•
Always ensure that the webbing of the
seat belts is properly routed. Seat
belts which are not correctl
y adjusted can 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 pr
oduced in an accident and is then
suddenly held firm by the belt.•
Only insert the lock tongue into the lock which is the correct one for your
seat. This will affect the protection which
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. – Move the height adjuster in the desired direction up or down
⇒fig. 135
.
– Then pull firmly on the belt to ensure that
the seat belt height adjuster has correctly
locked in place.WARNING (continued)

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.

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!
Note
•
All four wheels must be fitted with the same tyres in order to achieve problem-free
operation of the TCS. Differing rolling circumferences of the tyres can lead to an unde- sirable reduction in the engine output.•

Active driver-steering recommendation (DSR)*Vehicles with ESP are equipped with active driver-steering recommendation (DSR). This function indicates to the driver in critical situations a steering recommendation in order to stabilise the vehicle. The active driver-steering recommendation is activated, for example, on the right and left vehicle si
de when braking sharply on different road
surfaces.
WARNING
Even with this function the vehicle canno
t steer itself! The dr
iver is furthermore
responsible for the steering of the vehicle!BrakesWhat has a negative effect on braking efficiency?Wear-and-tear Wear-and-tear to the brake pads is greatly dependent on the operating conditions of the vehicle and your style of driving. Particul
arly if you drive a great deal in towns and
over short distances or if you adopt a sporty style of driving, it may be necessary to have the thickness of the brake pads inspected at a specialist garage between the service inspections. Wet roads or road salt There may be a certain delay before the brakes
take full effect under certain conditions
such as when driving through water, during
heavy rain showers or after the vehicle has
been washed in an automatic vehicle wash
, since the brake discs and brake pads may
be moist or even have a coatin
g of ice on them in winter.
Yo u s h o u l d d r y t h e b r a k e s a s
soon as possible by applying and
releasing the brakes several times.
There also may be a certain delay before the full braking efficiency is available when driving on roads which have been treated with
road salt if you have not used the brakes
for some considerable time beforehand. The layer of salt on the brake discs and brake pads must first be rubbed off when you apply the brakes.
Corrosion Corrosion on the brake discs and dirt on th
e bake pads occur if
the vehicle has been
parked for a long period and if you do
not make much use of the braking system.
We recommend cleaning the brake discs by firm
ly applying the brakes at a fairly high
speed if you do not make much use of the braking system or if surface corrosion is present
⇒
.
Faults in the brake surface If you notice that the braking distance has
suddenly become longer and that the brake
pedal can be depressed further, it is possib
le that a brake circuit of the dual-circuit
brake system has failed. Drive, in such cases, to the nearest specialist garage without delay in order to have the problem rectifie
d. Drive at a reduced speed while on your
way to the dealer and adapt your style of
driving to the higher brake pedal pressure
required. Low brake fluid level An insufficient level of brake fluid may result in problems in the brake system. The level of the brake fluid is monitored electronically
⇒page 37, “Brake system
”.
WARNING
•
Only apply the brakes for the purpose of
drying and cleaning the brake discs
if the traffic conditions permit this. Do not place any other road users in jeop-ardy.•
When retrospectively mounting a front
spoiler, solid wheel hubs etc. one
must ensure that the air supply to the front wheel brakes is not reduced other-wise the braking system could run too hot.•
Allow for the fact that new brake pads
do not achieve their full braking effi-
ciency until approximately 200 kilometres. New brake pads must be first “run in” before they develop their optimal fric
tion force. You can, however, compen-
sate for this slightly reduced braking fo
rce by increasing the pressure on the
brake pedal. This guideline also applie
s to any new brake pads installed at a
future date.

Caution
•
Never allow the brakes to rub by applying sl
ight pressure if you do not wish to brake
the vehicle. This causes the br
akes to overheat and can also result in a longer braking
distance and excessive wear.•
Before negotiating a steep downhill section, please reduce your speed, shift down
into the next lower gear (manual gearbox)
or select a lower driving stage (automatic
gearbox). This enables you to make full us
e of the braking power of the vehicle and
reduces the strain on the brakes. Any additional braking should be done intermittently, not continuously.
Note
The brake light flashes automatically in case
of an emergency braking at speeds greater
than 60 km/h or with the intervention of the ABS, which lasts longer than 1.5 seconds. After the speed was reduced below 10 km/h or the vehicle was stopped, the brake light stops flashing and the hazard warning light system switches on. The hazard warning light system is switched off automatically
after accelerating
or driving off again.
Brake boosterThe brake booster boosts the pressure which you generate with the brake pedal. The necessary pressure is only genera
ted when the engine is running.
WARNING
•
Never switch off the engine before the vehicle is stationary.
•
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.
Antilock brake system (ABS)ABS prevents the wheels locking when braking.General The ABS contributes significantly to enhanc
ing the active safety of your vehicle.
Compared to a vehicle not fitted with the ABS brake system, you are able to retain optimal steering ability even during a full br
ake application on a slippery road surface
because the wheels do not lock up. You must not expect, however, that the br
aking distance will be shorter under all
circumstances as a result of the ABS. The braking distance for example on gravel and fresh snow, when you should anyway be driv
ing slowly and cautiously, will be longer.
Operating principle The brake pressure will be reduced on a wheel which is rotating at a speed which is too low for the speed of the vehicle and tending
to lock. This control
cycle is noticeable
from a
pulsating movement of the brake pedal
which is accomp
anied by noises.
This is consciously intended to provide the driver with the information that the wheels are tending to lock (ABS control range). You must always keep the brake pedal depressed to enable the ABS to optimally control the brake application in this braking range. Never interrupt the application of the brakes! ABS Off-road* After switching on the Off-road mode
⇒page 170, ABS Off-road is activated.
ABS Off-road increases the braking power of
the vehicle on an unfirm ground, as it
keeps the wheels blocked for a longer period
of time when the brake is applied while
sliding. The system is only available, if the front wheels are in the straight-ahead posi-tion. The system operates at speeds of up to 50 km/h.
WARNING
•
The ABS can also not overcome the physical
limits of your ve
hicle. Please do
not forget this, particularly when driving on icy or wet road surfaces. If the ABS is operating within the control range, adapt your speed immediately to the conditions of the road surface and the traffic situation. The increased safety
