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

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

offered by the ABS must not tempt you to take greater risks than otherwise - risk of an accident!•
The normal braking system is
still fully functional if there is an ABS fault.
Visit a specialist garage as quickly as poss
ible and adjust your style of driving to
take account of the ABS fault in the meantime since you will not know the extent of the fault and in how far the braking efficiency is affected.
Note
•
A warning light comes on if a fault occurs in the ABS system
 ⇒page 36.
•
Changes to vehicle (e.g. on engine, on th
e brakes, on chassis or another combina-
tion of tyres and wheels) can in
fluence the function of the ABS
⇒page 221, “Accesso-
ries, changes and replacement of parts”.Brake Assist*During a severe brake application (e.g. if a hazard exists), the Brake Assist increases the braking force and thus makes it possible to
rapidly produce the pressure required in
the brake system. The majority of drivers do apply the brakes
in good time in dangerous situations, but
do not depress the brake pedal with sufficient
pressure. Consequently, it is not possible
for the vehicle to achieve its maximum deceleration and the vehicle covers a greater distance than necessary. The Brake Assist is activated by the very quick operation of the brake pedal. In such cases, a much greater braking pressure exists
than during a normal
brake application.
This makes it possible, even with a relative
ly low resistance of the brake pedal, to
produce an adequate pressure in the brake system in the shortest possible time, which is required for maximum deceleration of th
e vehicle. You must apply the brake pedal
firmly and hold it in this position in order to achieve the shortest possible braking distance. The Brake Assist is able to help you achieve a shorter braking distance in emergency situations by rapidly producing the pressure required in the brake system. It fully exploits the attributes of the ABS. After you release the brake pedal, the function of the Brake Assist is automatically switched off
and the brakes operate in the normal way.
The Brake Assist is part of the ESP system. If a fault occurs in the ESP, the Brake Assist function is also not available.
Further information on the ESP
⇒page 163.
WARNING
•
The Brake Assist is also not able to overcome the physical limits of your
vehicle in terms of the braking distance required.•
Adapt your speed to the conditions of th
e road surface and to the traffic situ-
ation.•
The increased safety offered by the Brake Assist must not tempt you to take
a greater safety risk than otherwise.Uphill-Start off-Assist*The uphill-start off-assist makes it much easier to start off on steep hills. The system assists a start off by holding the brake pressure produced by the brake pedal actuation for approx. 2 seconds after releasing the brake pedal. The driver can therefore move his foot from the brake pedal to the accelerator pedal and start off on the slope, without having to actuate the handbrake. The brake pressure drops gradually the more you operate the accelerator pedal. If the vehicle does not start off within 2 seconds, it starts to roll back. The uphill-start off-assist is active in the ev
ent of a 3 % slope, if the vehicle door is
closed. It is always active on slopes when in forward or reverse start off. When driving downhill, it is inactive.Electromechanical power steeringThe power steering enables you to steer the vehicle with less physical force. With the electromechanical power steering, the steering assist is automatically adapted to the speed and to the steering angle. It is still possible to fully steer the vehicle if the power steering fails or if the engine is not running (vehicle being towed in). The only difference is that greater physical effort is required.

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.

and the new calibration is started, which is confirmed with an audible signal and then the warning light
 goes out.
•
If the warning light

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.

Note
The tyre inflation pressure-control system:•
does not replace the regular tyre inflatio
n pressure control, because the system
cannot detect an even pressure loss;•
cannot warn in case of very rapid tyre inflation pressure loss, e.g. in case of sudden
tyre damage. In this case carefully bring the vehicle to a standstill without sudden steering movements and without sharp braking.•
In order to ensure a proper functioning
of the tyre inflation pressure-control
system, it is necessary to carry out the basic setting again every 10 000 km or 1x a year.Diesel particle filter* (diesel engine)In the diesel particle filter the resu
lting soot particles are collected and
burnt during the combustion of diesel fuel.Code

, indicates that your
vehicle is equipped
with a diesel particle filter. The ve
hicle data sticker is located on
the floor of the luggage compartment and is also stated in the Service schedule. The diesel particle filter filters the soot particles completely from the exhaust. The soot is collected in the diesel particle filter and
burnt regularly. To assist this procedure, we
recommend not to drive regu
larly over short distances.
If the diesel particle filter is clogged or there
is a fault, it is indicated by the warning light

WARNING
•
The diesel particle filter
achieves very high temp
eratures. Therefore do not
park at points where the hot filter comes into direct contact with dry grass or other combustible materials - risk of fire!•
Never use additional underbody protection or corrosion-protection agents
for the exhaust pipes, catalytic converters,
diesel particle filter
or heat shields.
When the engine reaches its operating
temperature, these
substances might
ignite - risk of fire.
Note
•
When using diesel fuel with high sulphur cont
ent the life of the diesel particle filter
is clearly reduced. A specialist garage will
be able to tell you which countries use only
diesel fuel with high sulphur content.Off-road*GeneralThe Off-road mode comprises functions which assist off-road driving. The following functions are integrated in the Off-road mode:•

WARNING
•
Never drive too fast, particularly not around curves, and never undertake
extreme driving manoeuvres.•
Always adjust your speed and adapt your style of driving to suit road, off-
road, traffic and weather conditions.•
In case the vehicle is stationary on a hi
llside at a steep angl
e, do not exit the
vehicle when it is facing downhill. Throug
h this the overall centre of gravity can
shift in such a way that the vehicle tilts and rolls down the hillside - hazard! Always carefully exit your vehicle on the side facing uphill
⇒page 186.
•
A lack of experience and knowledge when
driving off-road can lead to crit-
ical situations an
d serious injuries.
•
Never choose a dangerous route and never take a risk which could jeop-
ardize your safety and that of your passengers. If you cannot go on or if you doubt the safety of the route, turn back and choose another way. Even a terrain, which looks harmless, can be difficult and dangerous, and may bring you and your passengers into
a critical
situation.
•
If you have not fastened your seat belt correctly or you are not wearing your
seat belt at all, or you are holding th
e steering wheel incorrectly when driving
off-road, the risk of severe or even fata
l injuries increases.
Correctly fastened
seat belts reduce serious injuries in case of sudden braking manoeuvers and accidents. As long as the vehicle is in motion, always have your seat belt and those of your passen
gers correctly fastened. Take yo
ur thumbs off the steering
wheel when driving off-road. Should resist
ance build up in front of the wheels,
the steering wheel may suddenly and unexpect
edly spin and hur t you. Hold the
steering wheel with both hands firmly on
the outer edge in the 9 o'clock and 3
o'clock position.•
If you have not fastened your seat belt correctly or you are not wearing your
seat belt at all, or you are holding th
e steering wheel incorrectly when driving
off-road, the risk of severe or
even fatal injuries increases.
•
Correctly fastened seat belts reduce serious injuries in case of sudden
braking manoeuvers and accidents. Th
erefore you and your passengers must
always fasten your seat belts correctl
y as long as the vehicle is moving.
•
Take your thumbs off the steering wh
eel when driving off-road. If the
wheels hit an obstacle, the steering wh
eel may suddenly and unexpectedly spin
and hurt you!•
Never use the cruise control system when driving off-road. The use of the
cruise control system when driving off-
road is unsuitable and can even be
dangerous.•
Do not drive over embankments, ramps or
hillsides at too high a speed. This
can lead to the wheels of the vehicle lifting off the ground so that you can no longer steer and control the vehicle.•
If the wheels lose contact with the
ground, for example when the vehicle
rebounds while driving over
corrugations, steer straight ahead. If the wheels
are turned when making the contact with
the ground again, the vehicle can roll
over.•
There should never be any person in front or behind the vehicle when rocks,
scrub, wood pieces or other objects ar
e placed under the wheels in order to
achieve traction on a sandy or slippery ground. Turning the wheels can trans-form these objects into dangerous “bullets” – hazard!Warning of a rolloverVehicles of this type
have a higher centre of gravit
y than ordinary vehicles. This
increases the risk of vehicle rollover when driving on-road and off-road. Therefore, you must always pay attention to the safety information which is stated in the Owner's Manual.

Safe off-road drivingAdopt a correct seated position and always fa
sten the seat belt correctly. Make sure
that your front passenger and your passengers
seated on the rear seats always fasten
their seat belts correctly. When driving off-road, it is perhaps more useful to adopt a slightly different seated position. Depending on the terrain, an incr
eased force may be required to turn the
steering wheel because the force is transferred from the front wheels to the steering wheel. You must be seated in such a way that you have good front visibility, especially when driving uphill or dow
nhill. You must never be seat
ed in such a way that the
distance between your chest and the midd
le of the airbag cover is less than
25 cm

⇒ page 148. Under no circumstances must you drive off-ro
ad with high heels,
slippery or open
shoes. You should wear shoes which fit your fe
et well and allow you to get a feel for the
pedals.
WARNING
Observe the important guidelines
⇒page 180.
Before driving off-road•
Make sure the tyres are suitable for the planned off-road journey. Before you drive
through difficult terrai
n, equip your vehicle with off-road tyres.
•
Fill up your tank. The fuel consumption of
the vehicle is much higher when driving
off-road than when driving on the road.•
Install the towing eye at the front or at the rear before driving off-road. It is not
always possible to install the towing eye if the vehicle got stuck.•
Always check the inflation pressure of a
ll the tyres and if necessary correct it.
•
Check the vehicle tool kit and suppl
ement it according to your needs.
•
Fill with engine oil up to the line , so that the engine is sufficiently supplied with
engine oil when the vehicle is in a tilted position
⇒page 205, “Check engine oil level”.
•
Top up wash fluid.
•
Stow your load as low as possible in the vehicle and attach all the items which are
loose.Off-road driving•
Never be alone when driving off-road and be prepared to encounter unexpected
situations. Travel together with at least two off-road vehicles. Equipment with which you can call for help in an em
ergency is partic
ularly useful.
•
Drive slowly through unclear terrain.
•
You must stop when encountering difficul
t passages and explore the continuation
of the route on foot. If you cannot go on or
if you doubt the safety of the route, turn
back and choose another way.•
Drive slowly over hilltops. Make sure that
the wheels of the vehicle do not lift off
the ground, as this could severely damage
the vehicle and it may become disabled.
•
Drive slowly on difficult stretches of the route. When driving on a slippery ground,
shift up into the next higher gear and make
sure that the vehicle always stays in motion.
Do not drive too fast so that you don't lose control over your vehicle.•
If your vehicle got stuck in
sand, snow or sludge, it may be more effective to reverse
the vehicle than trying to drive forwards.•
Place stones, footmats or pieces of wood
under the spinning wheels in order to
achieve traction on a sandy or slippery ground.•
Do no drive through water before reading what you must take into account
⇒ page 179.•
Keep sufficient distance from other vehicles even at low speeds. When the first
vehicle suddenly gets stuck, the following vehi
cle can still stop in time without getting
stuck itself.•
Do not plan day trips which are too far in distance.
•
Do not use the cruise control system when
driving off-road. It is only intended for
driving on the road.
WARNING
•
The intelligent engineering of your ve
hicle cannot overco
me the physical
limits of your vehicle.
