WARNING

Stow the objects in the luggage compartment and attach them to the
lashing eyes.

Loose objects in the passenger compartment can be thrown forward during
a sudden manoeuvre or in case of an accident 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 compar tment should be stowed in such a
way that no objects are able to slip fo rward if there are any sudden driving or
braking manoeuvres undertaken - risk of injury!

When transporting fastened objects which are sharp and dangerous in the
luggage compartment enlarged by folding the rear seats forward or removing
the rear seats, ensure the safety of the passengers transported on the other rear
seats page 111, “Correct seated position fo r the occupants on the rear seats”.

If the rear seats next to the folded forward seat are occupied, ensure
maximum safety, e.g. by placing the goods to be transported in such a way that
a folding back of the seat is prev ented in case of a rear collision.

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 page 173, fig. 143.

The circulation of air in the vehicle help s to prevent the windows from misting up.
The used air streams out through the air venting slits which are located under the
bumper in the luggage compartment. Check fo r yourself that the air venting slits are
not covered.
Vehicles of category N1On vehicles of the category N1, which are no t fitted with a protective grille, a lashing
set which complies with the standard EN 12195 (1 - 4) must be used for fastening the
load.Fastening elementsFixing eyes are located on th e sides of the loading area for lashing the goods to be
loaded fig. 57 .
You can also attach fixing nets* to these fixing eyes for holding small objects.
The fixing nets* and the installation inst ruction are located in the luggage compart-
ment.
WARNING

The load to be transported must be fixed in place in such a way that it cannot
move during the journey and when braking.

If the items of luggage or objects are attached to the lashing eyes with
unsuitable or damaged lashing straps, inju ries can occur in the event of braking
manoeuvres or accidents. In order to prevent the items of luggage being thrown

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);

Antilock brake system (ABS);

Brake Assist;

Uphill Start Assist
Operating principle
The ESP switches on automati cally 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 vehicle 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 fo r 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.
If the ESP helps to stabilise the vehicle (f or example when applying and releasing a
braking force to an individual wheel), then the indicator light
 flashes quickly.
The ESP system cannot be switched off, only the TCS system can be switched off by
pressing the button page 134, fig. 126. The warning light
  page 30 lights up if
the TCS system is switched off.
The warning light
 lights up permanently if there is a fault in the ESP system.
The fact that the ESP system operates together with the ABS means that the ESP
warning light will also come on if the ABS system is not operating properly.
If the warning light  comes on immediately after starting the engine, the ESP system
can be switched off for technical reasons. In this case, the ESP system can be switched
on again by switching the igni tion on and off. If the warning light goes out, the ESP
system is fully functional 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 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.

Technical Data
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 greater driving force to the other driven wheel.
This control process 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 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. 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 or TCS 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 th e brakes, on chassis or another combina-
tion of tyres and wheels) can in fluence the function of the EDL page 179, “Accesso-
ries, changes and replacement of parts”.
BrakesWhat has a negative effect on braking efficiency?Wear-and-tear
Wear-and-tear to the brake pa ds is greatly dependent on the operating conditions of
the vehicle and your style of driving. Particularly 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 insp ected 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 un der 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 coating of ice on them in winter. You should dry the brakes as
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 rectified. 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.

WARNING

The ABS can also not overcome the physical limits of your vehicle. 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

tion of tyres and wheels) can in fluence the function of the ABS page 179, “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 achi
eve 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 133.
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 the 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 Assist*The uphill start assist makes it 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 assist is active as of a 3% slope, if the driver door is closed. It is always
active on slopes when in forward or reverse start off. When driving downhill, it is
inactive.Electrohydraulic power steeringThe power steering enables you to steer the vehicle with less physical force.
The steering characteristics can be changed by a specialist garage.

You will place great stresses on the power steering system if the steering is turned to
full lock when the vehicle is stationary. Turn ing the steering to full lock in such a situa-
tion will be accompanied by noises.
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.
It is possible that the hydraulic pump of the power steering will not run due to the low
vehicle network voltage if the battery has gone flat and the engine must started with
the help off jump leads. This condition will be indicated by lighting up of the warning
light.
The power steering operates again if the ba ttery is charged to a specific range when
engine is running. It also op erates again, if the engine can be started with its own
battery.
If there is a fault in the power steering, the warning light lights up in the instrument
cluster
  page 25.
Caution
Do not leave the steering at full lock fo r more than 15 seconds when the engine is
running - risk of damaging the power steering!
Note
Have the steering inspected as soon as possible by a specialist garage if there is a leak
or fault in the system.
Tyre pressure monitoring system*The tyre pressure monitoring system compares with the aid of the ABS sensors the
speed and also the rolling circumference of the individual wheels. If the tyre inflation
pressure is significantly changed and thus the rolling circumference of a wheel, the
warning light
 lights up in the instrument cluster page 30. The tyre pressure moni-
toring system functions late or too sensitively if:

the structure of the tyre is damaged,

the vehicle is loaded to one side or with a load on the roof,

the wheels of an axle are loaded heavily (e.g. when towing a trailer or when driving
uphill or downhill),

the vehicle is operated in unfavourable wi nter conditions or on an unfirm ground,

snow chains or emergency wheel are mounted,

the driver has a sporty style of driving (with sharp acceleration and high speed
when cornering).
Basic setting of the system
After changing the tyre inflation pressures or after changing one or several wheels, a
basic setting of the system mu st be carried out as follows.

Inflate all tyres to the specified inflation pressure page 173.

Switch on the ignition.


Technical Data

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.
Functional description
After the basic setting of the system the “adaptation” of the tyre inflation pressures and
then the tyre pressure control in the individual tyres are performed.
Warning light
 lights up
If the tyre inflation pressure of at least one wheel is insufficiently inflated in comparison
to the stored basic value, the warning light
  lights up. Inflate all tyres to the
specified inflation pressure  page 173, “Tyre life” and then perform a basic setting of
the system.
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 correct 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 pressure monitoring system does not take away the responsibility
from the driver for the correct tyre inflation pressure.Note
The tyre pressure monitoring 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 ca refully bring the vehicle to a standstill without sudden
steering movements and without sharp braking.
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 7GG, 7MB or 7MG on the vehicle data sticker, see fig. 128 , indicates that your
vehicle is equipped with a diesel particle fi lter. The vehicle 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 
 page 32, “Diesel particle filter*  (diesel engine)”.
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.
