Safe driving
– Distribute the load evenly in the luggage compartment.
– Place heavy objects as far forward as possible in the luggage
compartment.
– Place the heavy objects first.
– Secure heavy objects to the fitted fastening rings ⇒ page 17.
WARNING
● Loose luggage and other objects in the luggage compartment could
cause serious injuries.
● Always stow objects in the luggage compartment and secure them on
the fastening rings.
● Use suitable straps to secure heavy objects.
● During sudden manoeuvres or accidents, loose objects can be thrown
forward, injuring vehicle occupants or passers-by. This increased risk of
injury will be further increased if a loose object is struck by an inflating
airbag. If this happens, objects can be transformed into “missiles”. Risk
of fatal injury.
● Please note that the centre of gravity may shift when transporting
heavy objects; this may affect the vehicle's handling and lead to an acci-
dent. Therefore, it is essential to adjust your speed and driving style ac-
cordingly, to avoid accidents.
● Never exceed the allowed axle weights or allowed maximum weight.
If the allowed axle load or the allowed total weight is exceeded, the driv-
ing characteristics of the vehicle may change, leading to accidents, inju-
ries and damage to the vehicle.
● Never leave your vehicle unattended, especially when the rear lid is
open. Children could climb into the luggage compartment, closing the
door behind them; they will be trapped and run the risk of death.
WARNING (Continued)
● Never allow children to play in or around the vehicle. Close and lock
all the doors and rear lid when you leave the vehicle. Before you lock the
vehicle, make sure that there are no adults or children in the vehicle.
● Never transport passengers in the luggage compartment. All passen-
gers must have their seat belt fastened ⇒ page 19.
Note
● Air circulation in the vehicle helps reduce fogging of the windows. Used
air escapes through ventilation slits in the side trim of the luggage compart-
ment. Ensure that the ventilation slits are never covered.
● Straps for securing the load to the fastening rings are commercially
available. 
Fastening rings
There can be four fastening rings in the luggage compart-
ment for fastening luggage and other objects.
– Always use suitable and undamaged straps to secure luggage
and other objects to the fastening rings ⇒ 
in Loading the lug-
gage compartment on page 17.
– Pull up the fastening rings to attach the straps.
During a collision or an accident, even small and light objects can build up
so much energy that they can cause very severe injuries. The amount of ki-
netic energy depends on the speed of the vehicle and the weight of the ob-
ject. The most significant factor, however, is the speed of the vehicle.
Example: An object weighing 4.5 kg is lying unsecured in the vehicle. Dur-
ing a frontal collision at a speed of 50 km/h, this object generates a force
corresponding to 20 times its weight. That means that the effective weight 

Seat belts
WARNING
● If the seat belts are worn incorrectly or not at all, the risk of severe
injuries increases. The optimal protection from seat belts can be ach-
ieved only if you use them properly.
● Fasten your seat belt before every trip - even when driving in town.
The other passengers must also wear the seat belts at all times, other-
wise they run the risk of being injured.
● The seat belt cannot offer its full protection if the seat belt is not
positioned correctly.
● Never allow two passengers (even children) to share the same seat
belt.
● Keep both feet in the footwell in front of your seat as long as the vehi-
cle 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 al-
ter the position of the belt webbing.WARNING (Continued)
● Frayed or torn seat belts or damage to the connections, belt retrac-
tors or parts of the buckle could cause severe injuries in the event of an
accident. Therefore, you must check the condition of all seat belts at reg-
ular 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 226.

26Seat belts
Pregnant women must also fasten their seat belts properly
The best protection for the unborn child is for the mother to
wear the seat belt properly at all times during the pregnan-
cy.
Fig. 14 Positioning seat
belts during pregnancy
The seat belt provides maximum protection only when the seat belt
is properly positioned ⇒ page 25.
– Adjust the front seat and head restraint correctly ⇒ page 10.
– Holding the latch plate, pull the belt evenly across your chest
and as low as possible over the pelvis ⇒ Fig. 14.
– Insert the latch plate into the buckle for the appropriate seat
and push it down until it is securely locked with a click ⇒ 
.
– Pull the belt to ensure that the latch plate is securely engaged
in the buckle.
WARNING
● An incorrectly worn seat belt can cause severe injuries in the event of
an accident.
● For pregnant women, the lap part of the seat belt must lie as low as
possible over the pelvis, never across the stomach, and always lie flat so
that no pressure is exerted on the abdomen.
● Read and observe the warnings ⇒ page 22.

WARNING (Continued)
● To reduce the risk of injury from an inflating airbag, always wear the
seat belt properly ⇒ page 19.
● Always adjust the front seats properly.

The danger of fitting a child seat on the front passenger
seat
Rear-facing child seats must never be used on the front pas-
senger seat when the front passenger airbag is enabled. The front passenger airbag is a serious risk for a child if it is activated. The
front passenger seat is life threatening to a child if he/she is transported in
a rear-facing child seat. Children up to 12 years old should always travel on
the rear seat.
If a rear-facing child seat is secured to the front passenger seat, an inflating
airbag can strike it with such force that it can cause critical or fatal injuries.
Therefore we strongly recommend you to transport children on the rear
seats. That is the safest place for children in the vehicle. Alternatively, the
front passenger airbag can be disabled with a key-operated switch
⇒ page 45. When transporting children, use a child seat appropriate to
the age and size of each child ⇒ page 47.
For those vehicles that do not include a key lock switch to disconnect the
airbag, the vehicle must be taken to a Technical Service.
WARNING
● If a child seat is secured to the front passenger seat, the risk to the
child of sustaining critical or fatal injuries in the event of an accident in-
creases.
● Never secure a rear-facing child seat to the front passenger seat if the
front passenger airbag is enabled. The child can suffer critical or fatal in-
juries if the front passenger airbag is triggered.
● An inflating front passenger airbag can strike the rear-facing child
seat and hurl it with great force against the door, the roof or the back-
rest.
● If, under special circumstances, it is necessary to transport a child in
a rear-facing child seat on the front passenger seat, it is absolutely es-
sential that you observe the following safety measures:
–Deactivate the front passenger airbag ⇒ page 45, Deactivating
airbags.
– The child seat must be approved by the child seat manufacturer for
use on a front passenger seat with front or side airbag.
– Follow the installation instructions given by the child seat manu-
facturer and observe the safety instructions ⇒ page 47, Child safe-
ty.
– Before properly installing the child seat, push the front passenger
seat completely backwards so that the greatest possible distance to
the front passenger airbag is ensured.
– Ensure that no objects prevent the front passenger seat from being
pushed completely back.
– The backrest of the front passenger seat must be in an upright po-
sition.

48Child safety
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 nec-
essary, in exceptional cases, to transport a child in the front passenger
seat, the front passenger airbag must always be disabled ⇒ page 45, De-
activating 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 potential-
ly fatal injuries to the child!
● Never allow a child to be transported in a vehicle without being prop-
erly secured, or to stand up or kneel on a seat while travelling. In an acci-
dent, 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 impor-
tant if the child is travelling on the front passenger seat and the airbag
system is triggered in an accident; as this could cause serious injury or
even death.
● A suitable child seat can protect your child!
● Never leave an unsupervised child alone on a child seat or in the vehi-
cle.
● Depending on weather conditions, it may become extremely hot or
cold inside the vehicle. This can be fatal.WARNING (Continued)
● 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 abdomi-
nal 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 colli-
sion 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 49, Child seats.

2 remote control keys
In certain European markets, vehicles with alarm are equipped with 2 re-
mote control keys.
WARNING
● Always take the key with you when leaving the vehicle, even if you
only intend to be gone for a short time. This is particularly important if
there are children in the vehicle, as they might otherwise be able to start
the engine or use power-operated equipment (e.g. the electric windows),
which could cause injuries.
● Wait for the vehicle to come to a standstill before removing the igni-
tion key from the lock! Otherwise, the steering lock could engage sud-
denly, causing an accident.

102Unlocking and locking
Automatic locking function (Auto Lock)*
The Auto Lock* function automatically locks all doors and the rear lid when
the vehicle exceeds a speed of about 15 km/h.
The vehicle is unlocked again automatically when the ignition key is re-
moved. Alternatively, the driver can also unlock the vehicle using the central
locking switch  or by opening one of the doors.
WARNING
Do not leave anyone (especially children) in the vehicle if it is locked from
the outside and the anti-theft security system is enabled, as the doors
and windows cannot then be opened from the inside. Locked doors could
delay assistance in an emergency, potentially putting lives at risk.
Note
● Should the central locking system fail to work, you can still lock and un-
lock the driver door and the rear lid using the key. Locking the doors man-
ually if central locking fails to work ⇒ page 105.
● The anti-theft mechanism and the anti-theft alarm* cannot be enabled if
the central locking is not working.
