54 Safety and Security
Occupant safety
Installation of infant and child restraint
systems
This vehicle is equipped with tether an-
chorages for a top tether strap at each of
the rear seating positions.
Top tether straps enable an additional con-
nection to be made between child restraint
systems secured with LATCH-type anchors
and rear seats. This can further reduce the
risk of injury.
Warning!G
Infants and small children should never
share a seat belt with another occupant.
During an accident, they could be crushed
between the occupant and seat belt.
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle
and/or the child is not properly secured in
the child restraint.
Children too big for a toddler restraint must
ride in seats using regular seat belts. Posi-
tion shoulder belt across chest and shoul-
der, not face or neck. A booster seat may be
necessary to achieve proper seat belt posi-
tioning for children over 41 lbs until they
reach a height where a lap/shoulder belt fits
properly without a booster.
When the child restraint is not in use,
remove it from the vehicle or secure it with
the seat belt to prevent the child restraint
from becoming a projectile in the event of
an accident.
Do not leave children unattended in the
vehicle, even if the children are secured in a
child restraint system. Unsupervised chil-
dren in a child restraint system may use
vehicle equipment and may cause an acci-
dent and/or serious personal injury.
Warning!G
Always lock backrest in its upright position
when rear seat bench is occupied by pas-
sengers, before installing top tether straps,
or the extended cargo compartment is not in
use. Check for secure locking by pushing
and pulling on the backrest. If the seat back-
rest is not properly locked, the seat back-
rest could fold. The child seat would no
longer be properly supported or positioned
to provide its intended benefit. That could
cause serious or even fatal injuries.

Seats
Removing and installing rear seat head
restraints (vehicles with split foldable
rear seat)
1Release button
Removing: Unlock the rear seat back-
rest and fold it slightly forward
(
page 281).
Pull head restraint to its highest
position.
Push release button1 and pull out

Warning!G
For your protection, drive only with properly
positioned head restraints.
Adjust the head restraint so that it is as
close to the head as possible and the center
of the head restraint supports the back of
the head at eye level. This will reduce the
potential for injury to the head and neck in
the event of an accident or similar situation.
Do not drive the vehicle without the seat
head restraints. Head restraints are
intended to help reduce injuries during an
accident.
iThe rear head restraints cannot be removed
on vehicles which do not have the split foldable
rear seat.
iAdjust the head restraint in such a way that
it is as close to the head as possible.

427 Practical hints
Resetting activated head restraints
Resetting activated head restraints
If the active head restraints (front seats)
have been triggered in an accident, the ac-
tive head restraints must be reset. Other-
wise, the active head restraints cannot
offer any additional protection in the event
of another rear-end collision.
You can tell that the head restraints have
been triggered when they have been
moved forward and cannot be adjusted.
