Technical Specifications
– Always reduce your speed as appropriate for road, traffic and
weather conditions.
– When travelling long distances, take breaks regularly - at least every two hours.
– If possible, avoid driving when you are tired or stressed.
WARNING
When driving safety is impaired during a trip, the risk of injury and acci-
dents increases.

Seat belts
24•Fasten your seat belt before every trip - even when driving in town. The
o t h e r pass e n ge rs m u s t al s o w ea r t h e s ea t b e l ts a t all t i m e s , o t h e r w is e t h e y
run the risk of being injured.•The seat belt cannot offer its full protection if the seat belt is not posi-
tioned correctly.•Never allow two passengers (even children) to share the same seat belt.•Ke e p b o t h fe e t i n t h e fo o t w e ll i n f ro n t o f yo u r s ea t as l o n g as t h e ve h ic l e
is in motion.•Never unbuckle a seat belt while the vehicle is in motion. Risk of fatal
injury.•The seat belt must never be twisted while it is being worn.•The seat belt should never lie on hard or fragile objects (such as glasses
or pens, etc.) because this can cause injuries.•Do not allow the seat belt to be damaged or jammed, or to rub on any
sharp edges.•Never wear the seat belt under the arm or in any other incorrect posi-
tion.•Loose, bulky clothing (such as an overcoat over a jacket) impairs the
proper fit and function of the belts, reducing their capacity to protect.•The slot in the seat belt buckle must not be blocked with paper or other
objects, as this can prevent the latch plate from engaging securely.•Never use seat belt clips, retaining rings or similar instruments to alter
the position of the belt webbing.•Frayed or torn seat belts or damage to the connections, belt retractors
or parts of the buckle could cause severe injuries in the event of an acci-
dent. Therefore, you must check the condition of all seat belts at regular
intervals.•Seat belts which have been worn in an accident and stretched must be
replaced by a specialised workshop. Renewal may be necessary even if
there is no apparent damage. The belt anchorage should also be checked.
•Do not attempt to repair a damaged seat belt yourself. The seat belts
must not be removed or modified in any way.•The belts must be kept clean, otherwise the retractors may not work
properly ⇒page 211.

Safety notes on using child seats
Proper use of child seats substantially reduces the risk of
injury in an accident!As the driver, you are responsible for any children you transport in
your vehicle.
– Protect your children by properly using the appropriate child
seats ⇒page 48.
– Always ensure that the seat belt is properly positioned according to the instructions provided by the manufacturer of the child
seat.
– When travelling, do not allow children to distract you from traffic.
– Take breaks regularly during long trips. Take a break at least
every two hours.
WARNING
•Never install a child seat facing backwards on the front passenger seat
unless the front passenger airbag has been disabled. This could lead to a
risk of potentially fatal injuries to the child! However, if it is necessary, in
exceptional cases, to transport a child in the front passenger seat, the front
passenger airbag must always be disabled ⇒page 44, “Deactivating
airbags*”. If the passenger seat has a height adjustment option, move it to
the highest position.•For those vehicles that do not include a key lock switch to disconnect
the airbag, the vehicle must be taken to a Technical Service.•All passengers, especially children, must assume the proper sitting
position and be properly belted in while travelling.
•Never hold children or babies on your lap, this can result in potentially
fatal injuries to the child!•Never allow a child to be transported in a vehicle without being properly
secured, or to stand up or kneel on a seat while travelling. In an accident,
the child could be flung through the vehicle, causing possibly fatal injuries
to themselves and to the other passengers.•If children assume an improper sitting position when the vehicle is
moving, they expose themselves to greater risk of injury in the event of a
sudden braking manoeuvre or in an accident. This is particularly important
if the child is travelling on the front passenger seat and the airbag system
is triggered in an accid ent ; as this could caus e s erious inj ur y or eve n deat h.•A suitable child seat can protect your child!•Never leave an unsupervised child alone on a child seat or in the
vehicle.•Depending on weather conditions, it may become extremely hot or cold
inside the vehicle. This can be fatal.•Children who are less than 1.5 metres tall must not wear a normal seat
belt without a child seat, as this could cause injuries to the abdominal and
neck areas during a sudden braking manoeuvre or in an accident.•Do not allow the seat belt to become twisted or jammed, or to rub on
any sharp edges.•Incorrectly worn seat belts can cause injuries even in a minor collision
or in sudden braking manoeuvres.•The seat belt provides maximum protection only when the seat belt is
properly positioned ⇒page 24, “Seat belts”.•Only one child may occupy a child seat ⇒page 48, “Child seats”.WARNING (continued)

The indicator lamp lights up when the main beams are on.The warning lamp
 is switched on once main beams are on or once the
headlight flasher is operating.
For further information see ⇒page 124.
Soot accumulation in the diesel engine particulate filter

If the warning lamp
 lights up you should help the filter clean itself by
driving in the appropriate manner.
To do this, drive about 15 minutes in fourth or fifth gear (automatic gearbox:
S gear range) at a speed of 60 km/h, with the engine running at approxi-
mately 2000 rpm. In this way, the pollen build up in the filter is burned. When
cleaning is successful, the indicator turns off.
If the warning lamp  does not turn off, or the three lamps turn on (partic-
ulate filter
, emission control system fault
 and glow plugs
D), take
the vehicle to a specialised workshop to repair the fault.
WARNING
•Always drive according to the road weather conditions, the terrain and
traffic. Driving recommendations should never lead to illegal manoeuvres
in surrounding traffic.•The diesel engine particulate filter may reach extremely high tempera-
tures; it should not enter into contact with flammable materials under-
neath the vehicle. Otherwise there is a risk of fire.
Anti-lock brake system (ABS)*
J
A warning lamp monitors the ABS.
The indicator lamp
J should light up for a few seconds when the ignition is
switched on. It goes out again after the system has run through an automatic
test sequence.
There is a fault in the ABS if:
•The warning lamp
J does not light up when the ignition is switched on.
•The warning lamp does not go out again after a few seconds•The warning lamp lights up when the vehicle is moving
The vehicle can still be braked in the normal way, without the ABS function.
Take the vehicle to a specialised workshop as soon as possible. For further
information on the ABS go to ⇒page 185.
If a fault occurs in the ABS, the ESP* warning lamp will also light up.
Brake system fault
If the ABS warning lamp
J lights up together with the brake warning lamp
H, this indicates not only a fault in the ABS function, but also a possible fault
in the brake system ⇒.
WARNING
•Before opening the bonnet, read and observe the warnings on
⇒ page 221, “Working in the engine compartment”.•If the brake warning lamp
H should light up together with the ABS
warning lamp
J, stop the vehicle immediately and check the brake fluid
level in the reservoir ⇒page 233, “Brake fluid”. If the fluid level has
dropped below the “MIN” mark you must not drive on. Risk of accident.
Obtain technical assistance.
•If the brake fluid level is correct, the fault in the brake system may have
been caused by a failure of the ABS system. This could cause the rear

With low outside temperatures, the air recirculation increases the effective-
ness of the heating system by heating the air inside the vehicle rather than
the air from outside.
Air distribution
Control for setting the flow of air in the required direction.
< – Air distribution towards the windscreen. If the windscreen air output is
on and the air recirculation mode is pressed, this remains active. When the
recirculation mode is on, if the air distribution towards the windscreen mode
is selected, the recirculation mode is deactivated. For safety reasons, the air
recirculation mode should not be connected. – Air distribution to the upper body – Air distribution to footwell – Air distribution to the windscreen and the footwell

The air flow can be set at four speeds with the knob . The air flow should
always be set at the lowest speed when driving slowly.
WARNING
•For road safety all windows must be clear of ice, snow, and condensa-
tion. This is essential to ensure good visibility. Please familiarise yourself
with the correct operation of the heating and ventilation system, including
the anti-fog/defrost functions for the windscreens.•In air recirculation mode, no cold air from the outside enters the vehicle
interior. The windows can quickly fog over if the heating is switched off.
