Replacing Airbag System Parts
after a Crash
{Warning
A crash can damage the airbag systems
in the vehicle. A damaged airbag system
may not properly protect you and your
passenger(s) in a crash, resulting in
serious injury or even death. To help
make sure the airbag systems are
working properly after a crash, have
them inspected and any necessary
replacements made as soon as possible.
If an airbag inflates, you will need to
replace airbag system parts. See your dealer
for service.
If the airbag readiness light stays on after
the vehicle is started or comes on when you
are driving, the airbag system may not work
properly. Have the vehicle serviced right
away. See Airbag Readiness Light 086.
Child Restraints
Older Children
Older children who have outgrown booster
seats should wear the vehicle’s seat belts.
The manufacturer instructions that come
with the booster seat state the weight and
height limitations for that booster. Use a
booster seat with a lap-shoulder belt until
the child passes the fit test below:
.Sit all the way back on the seat. Do the
knees bend at the seat edge? If yes,
continue. If no, return to the booster seat.
.Buckle the lap-shoulder belt. Does the
shoulder belt rest on the shoulder? If yes,
continue. If no, try using the rear seat belt comfort guide, if available. See
“Rear
Seat Belt Comfort Guides” under
Lap-Shoulder Belt 030. If a comfort guide
is not available, or if the shoulder belt
still does not rest on the shoulder, then
return to the booster seat.
.Does the lap belt fit low and snug on the
hips, touching the thighs? If yes, continue.
If no, return to the booster seat.
.Can proper seat belt fit be maintained for
the length of the trip? If yes, continue.
If no, return to the booster seat.
Q: What is the proper way to wear seat belts?
A: An older child should wear a lap-shoulder
belt and get the additional restraint a
shoulder belt can provide. The shoulder
belt should not cross the face or neck.
The lap belt should fit snugly below the
hips, just touching the top of the thighs.
This applies belt force to the child's
pelvic bones in a crash. It should never
be worn over the abdomen, which could
cause severe or even fatal internal
injuries in a crash.
Also see “Rear Seat Belt Comfort Guides”
under Lap-Shoulder Belt 030.

If the position you are using does
not have a head restraint and you
are using a dual tether, route the
tether over the seatback.
If the position you are using has a
fixed head restraint and you are
using a dual tether, route the
tether around the sides of the head
restraint.

hook to the anchor. Make sure that
you secure the top tether to the
top tether anchor and not to the
seatback latch.
3.5. Push rearward on the seatback until it locks into its upright position.
Push and pull on the seatback to
make sure it is secured properly.
4. Attach and tighten the lower attachments to the lower anchors. If the
child restraint does not have lower
attachments or the desired seating
position does not have lower anchors,
secure the child restraint with the seat
belt and the top tether. Refer to your child restraint manufacturer instructions
and
Securing Child Restraints (With the
Seat Belt in the Rear Seat) 064 or
Securing Child Restraints (With the Seat
Belt in the Front Seat) 069.
5. Tighten the top tether.
6. Before placing a child in the child restraint, make sure it is securely held in
place. To check, grasp the child restraint
at the LATCH path and attempt to move
it side to side and back and forth. There
should be no more than 2.5 cm (1 in) of
movement for proper installation.
Extended Cab with Rear Seats
{Warning
Never secure a rear-facing or
forward-facing child restraint in the left
rear seating position in an extended cab
model. This seating position is not
suitable for child restraint installation.
The seat cushion is too short to properly
support a rear-facing or forward-facing
child restraint. A child could be seriously
injured or killed in a sudden stop or
crash.
