Safe ty belts
Autom ati c s afet y belt retr actors
Every safety belt is equ ipped with an automa tic
be lt retractor on the shoulder belt. This feature
locks the belt when the belt is pulled out fast,
during hard braking and in a n accident . The belt
may a lso lock when you drive up or down a steep
hill or through a sharp curve. Dur ing normal driv­
ing the belt lets you
move freely .
Safety belt p ret en sion ers
The safety belts are equipped with a belt preten­
sioner that helps to t ighten the safety belt and
remove slack when the pretensioner is activated.
The function of the pretensioner is mon itored by
a warning light

Convertib le loc king retracto r
Every safety be lt except the one on the driver
seat is equipped with a convertible locking retrac­
tor that
mus t be used when the safety belt is
used to attach a child safety seat. Be sure to read
the impo rtant information about this feature

.&_ WARNING
Imprope rly pos itioned safety be lts can cause
ser ious injury in an accident

Safety belt position.
- Safety belts offer optimum protection only
when the seatback is upright and belts are
properly positioned on the body.
- Always make sure that the rear seat back­
rest to which the center rea r safety belt is
attached is secure ly latched whenever the
rear center safety belt is being used. If the
backrest is not securely latched, the passen­
ger will move forward with the backrest dur­
ing sudden braking, in a sudden maneuver
and especially in a crash.
- Never attach the safety belt to the buckle for another seat. Attaching the belt to the
wrong buckle will reduce safety belt effec­
tiveness and can cause serious persona l in­
jury.
- A passenger who is not properly restrained can be seriously in jured by the safety be lt it­
self when it moves from the stronger parts
134
of the body into critical areas like the abdo­ men.
- Always lock the convertible locking retractor
when you are securing a child safety seat in
the vehicle

chi ld restraint increases the risk of serious
personal injury and death.
- All vehicle occupants and especially children
must always be restrained properly whenev­
er riding in a vehicle.
- An unrestra ined o r improperly restrained
c hi ld can be injured o r killed by being
thrown aga inst the inside of the veh icle or
by being ejected from it during a sudden
maneuver or impact.

Child seats
Infant seats
Babies and infants up to about one year old and
20 lbs. or
9 kg need special rearward-facing
child restraints that support the back, neck and
head in a crash.

seats support the baby's back, neck and head in a
crash
c:>fig. 161.
The airbag on the passenger side makes the front
seat a potentially dangerous p lace for a child to
ride. The front seat is not the safest place for a
child in a forward -facing child seat. It is a very
dangerous place for an infant or a larger child in
a rearward-facing seat.
_&. WARNING
Not using a chi ld safety seat, using the wrong
child safety seat or improperly install ing a
child restra int increases the r isk of serious
personal injury and death in a crash.
- Never install rearward-fac ing ch ild safety
seats or infant carriers on the front passen­
ger seat - even w ith an Advanced A irbag Sys­
tem. A child w ill be seriously injured and can
be k il led when the inflat ing airbag hits the
child safety seat or infant carrier with great
force and smashes the child safety seat and
child against the backrest, center armrest,
door or roof
c:> page 139, Child restraints on
the front seat -some important things to
know.
-Always install rearward-fac ing ch ild safety
seats or infant carriers on t he rear seat.
- Never install a rearward-facing child re­
straint in the forward-facing direction. Such
restra ints are des igned for the special needs
of infants and very small ch ildren and can­
not protect them properly if the seat is for­
ward-facing.
- If you must install a rearward fac ing ch ild

Convertible child safety seats
Properly used convertible child safety seats can
help protect toddlers and children over age one
who weigh between 20 and 40 lbs. (9 and 18 kg)
in a crash.

Booster seats and safety belts
Properly used booster seats can help protect
children weighing between about 40 lbs. and 80
lbs. (18 kg and 36 kg) who ore less than 4 ft .
9
in. (57 inches/1.45 meters) tall.
Fig. 164 Rear seat: child properly restra ined in a booster
seat
The vehicle's safety belts alone will not fit most
children until they are at least 4
ft. 9 in. (57 in­
ches/1.45 meters) tall and weigh about 80 lbs.
(36 kg). Booster seats raise these children up so
that the safety belt will pass properly over the
stronger parts of their bodies and the safety belt
can help protec t them in a crash.
• Do not use the convertible locking retractor
when using the vehicle's safety belt to restrain
a child on a booster seat.
• The shoulder be lt must lie as close to the cen­
ter of the child's collar bone as possible and
must lie flat and snug on the upper body. It
must never lie across the throat or neck. The
lap belt must lie across the pelvis and never
across the stomach or abdomen. Make sure the
belt lies flat and snug. Pull on the belt to tight­
en if necessary .
• If you must transport an older child in a boos­
ter seat on the front passenger seat, you can use the safety belt he ight adjustmen t to help
adjust the sho ulder portion properly .
• Secu re unu sed safety belts on the rear seat
~page 163.
Children up to about 40 lbs. ( 18 kg) are best pro­
tected in ch ild safety seats designed for their age
166
and weight. Experts say that the skeletal struc­
ture, particularly the pelvis, of these children is
not fully developed, and they must not use the
vehicle safety be lts without a suitable child re­
straint.
It is usually best to put these children in appro­
priate booster seats. Be sure the booster seat
meets all applicable safety standards.
Booster seats raise the seating position of the
child and reposition both the lap and shoulder
parts of the safety belt so that they pass across
the chi ld's body in the right places. The routing of
the belt over the child's body is very important
for the child's protection, whether or not a boos­
ter seat is used. C hil dre n age 12 and u nder must
always ride in the rear seat.
Children who are at least 4 ft. 9 in. (57 inches/
1.45 meters) tall can generally use the vehicle's
three point lap and shoulder belts. Never use the
l ap belt portion of the vehicle's safety belt a lone
to restrain any child, regard less of how big the
child is . Always remember that children do not
have the pronounced pelvic structure required for
the proper function of lap be lt portion of the ve­
hicle's three point lap and shoulder belts. The
ch ild's safety absolutely requires that a lap belt
portion of the safety belt be fastened snugly and
as low as possible around the pelvis. Never let
the lap belt portion of the safety be lt pass over
the chi ld's stomach or abdomen.
In
a crash, airbags must inflate w ithin a blink of
an eye and with considerable force. In order to do its job, the airbag needs room to inflate so that it
will be there to protect the occupant as the occu­
pant moves forwa rd into the airbag.
A vehicle occupant who is out of pos it ion and too
close to the airbag gets in the way of an inflating
airbag. When an occupant is too close, he or she
will be struck vio lent ly and will receive serious or
possibly even fatal injury.
In order for the airbag to offer protect ion, it is
i mporta nt that all vehicle occupants, especially
any ch ildren, who must be in the fron t seat be­
cause of exceptional circumstances, be properly
restrained and as far away from the airbag as
possible. By keeping room between the child's ..,_

..... N
0 ::..:: co ..... ..... body and the front of the passenger compart­
ment, the airbag can inflate completely and pro­
vide supp lemental protect ion in certain frontal
collisions.
_&. WARNING
Not using a booster seat, using the booster
seat improperly, incorrectly installing a boos­
ter seat or using the vehicle safety belt im­ properly increases the risk of serious personal
injury and death in a collision or other emer­
gency situat ion. To help red uce the risk of se­
rious personal injury and/or death:
- T he shoulder be lt must lie as close to the
center of the child's collar bone as possible
and must lie f lat and snug on the upper
body. It must never lie across the throat or
neck. The lap belt must lie across the pelvis
and never across the stomach or abdomen.
Make sure the belt lies flat and snug. Pull on
the belt to tighten if necessary.
- Failure to properly route safety belts over a
child's body will cause severe injuries in an
accident or other emergency situation
¢page 130.
-The rear side of the child safety seat should
be pos itioned as close as poss ible to the
backrest on the vehicle seat. Adjust or re­
move the rear seat head restraint if it is d if­
ficult to install the child seat with the head restra int in place
¢page 62. Install the
head restraint again immediately once the
child seat is removed. Driving without head
restraints or with head restraints that are
not properly adjusted increases the risk of
serious or fatal neck injury dramatically.
- Children on the front seat of any car, even
with Advanced Airbags, can be seriously in­
jured or even killed when an airbag inflates.
- Never let a child stand or kneel on any seat.
- Never let a child ride in the cargo area of
your vehicle.
- Always remember that a child leaning for­
ward, sitting sideways or out of position in
any way during an accident can be struck by
a deploying airbag. This will result in serious personal injury or death .
