{CAUTION:
Never do this.
Here two children are wearing the same
belt. The belt cannot properly spread the
impact forces. In a crash, the two children
can be crushed together and seriously
injured. A belt must be used by only
one person at a time.
Q:What if a child is wearing a lap-shoulder
belt, but the child is so small that the
shoulder belt is very close to the child’s
face or neck?
A:If the child is sitting in a seat next to a
window, move the child toward the center of
the vehicle. Also seeRear Safety Belt
Comfort Guides on page 37. If the child is
sitting in the center rear seat passenger
position, move the child toward the safety belt
buckle. In either case, be sure that the
shoulder belt still is on the child’s shoulder, so
that in a crash the child’s upper body would
have the restraint that belts provide.

A forward-facing child seat (C-E) provides restraint
for the child’s body with the harness and also
sometimes with surfaces such as T-shaped
or shelf-like shields.A booster seat (F-G) is a child restraint designed
to improve the t of the vehicle’s safety belt
system. Some booster seats have a shoulder belt
positioner, and some high-back booster seats
have a ve-point harness. A booster seat can also
help a child to see out the window.

Airbag System
Your vehicle has a frontal airbag for the driver and
a frontal airbag for the right front passenger.
Your vehicle may also have roof-mounted side
impact airbags designed for either side impact or
rollover deployment. Roof-mounted side impact
airbags are available for the driver and the
passenger seated directly behind the driver and
for the right front passenger and the passenger
seated directly behind that passenger.
If your vehicle has roof-mounted side impact
airbags, the word AIRBAG will appear on
the airbag covering on the sidewall trim near the
driver’s and right front passenger’s window.
Even if you have no right front passenger seat in
your vehicle there is still an active frontal airbag
in the right side of the instrument panel. Do not
place cargo in front of this airbag.{CAUTION:
Be sure that cargo is not near an airbag.
In a crash, an in ating airbag might force
that object toward a person. This could
cause severe injury or even death.
Secure objects away from the area in
which an airbag would in ate. For more
information, seeWhere Are the Airbags?
on page 72andLoading Your Vehicle on
page 356.
Airbags are designed to supplement the protection
provided by safety belts. Even though today’s
airbags are also designed to help reduce the risk
of injury from the force of an in ating bag, all
airbags must in ate very quickly to do their job.

The right front passenger’s frontal airbag is in the
instrument panel on the passenger’s side.If your vehicle has a roof-mounted airbag for the
driver and the person seated directly behind
the driver, it is located in the ceiling above the
side windows.

If your vehicle has a roof-mounted airbag for the
right front passenger and the person directly
behind that passenger, it is located in the ceiling
above the side windows.
{CAUTION:
If something is between an occupant and
an airbag, the bag might not in ate
properly or it might force the object into
that person causing severe injury or even
death. The path of an in ating airbag must
be kept clear. Do not put anything
between an occupant and an airbag, and
do not attach or put anything on the
steering wheel hub or on or near any
other airbag covering. And, if your vehicle
has roof-mounted side impact airbags,
never secure anything to the roof of your
vehicle by routing the rope or tie down
through any door or window opening.
If you do, the path of an in ating side
impact airbag will be blocked. The path of
an in ating airbag must be kept clear.
