If the restraint system control unit detects a side
impact situation, the applicable components of
the restraint system are deployed independ-
ently of each other. If the system determines a
need for additional protection for the vehicle
occupants, the Emergency Tensioning Devices
are also deployed.
RSide impact air bag on the side on which the
impact occurs, independently of the Emer-
gency Tensioning Device and of the use of the
seat belt
RWindow curtain air bag on the side of the col-
lision, regardless of seat belt use and whether
front-passenger seat is occupied
iNot all air bags are deployed in an accident.
The various air bag systems work independ-
ently of each other.
How the air bag system works is determined
by the severity of the accident detected,
especially the vehicle deceleration or accel-
eration, and the apparent type of accident:
Rfrontal collision
Rside impact
Children in the vehicle
Important safety notes
Accident statistics show that children secured
in the rear seats are safer than children secured
in the front-passenger seat. For this reason, we
strongly advise that you install a child restraint
system on a rear seat. Children are generally
better protected there.
If a child younger than twelve years old and
under 5 ft (1.50 m)in height is traveling in the
vehicle:
Ralways secure the child in a child restraint
system suitable for this vehicle. The child
restraint system must be appropriate to the
age, weight and size of the child
Rbe sure to observe the instructions and safety
notes in this section in addition to the child
restraint system manufacturer's installation
instructions
GWARNING
If you leave children unsupervised in the vehi-
cle, they could set it in motion by, for example:
Rrelease the parking brake.
Rshift the automatic transmission out of the
parking position P.
Rstart the engine.
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
GWARNING
If persons, particularly children are subjected to prolonged exposure to extreme heat or
cold, there is a risk of injury, possibly even
fatal. Never leave children unattended in the
vehicle.
GWARNING
If the child restraint system is subjected to
direct sunlight, parts may get very hot. Chil-
dren may burn themselves on these parts,
particularly on the metal parts of the child
restraint system. There is a risk of injury.
If you leave the vehicle, taking the child with
you, always ensure that the child restraint
system is not exposed to direct sunlight. Pro- tect it with a blanket, for example. If the child
restraint system has been exposed to direct
sunlight, let it cool down before securing the
child in it. Never leave children unattended in
the vehicle.
Always ensure that all vehicle occupants have
their seat belts fastened correctly and are sitting
properly. Particular attention must be paid to
children.
Observe the safety notes on the seat belt
(
Ypage 40) and the notes on correct use of seat
belts (Ypage 41).
A booster seat may be necessary to achieve
proper seat belt positioning for children over
41 lbs (18 kg) until they reach a height where a
