What makes an air bag inflate?
In an impact of sufficient severity, the air bag sensing
system detects that the vehicle is in a crash. The sensing
system triggers a release of gas from the inflator, which
inflates the air bag. The inflator, air bag and related
hardware are all part of the air bag modules inside the
steering wheel and in the instrument panel in front of
the right front passenger.
How does an air bag restrain?
In moderate to severe frontal or near
-frontal collisions,
even belted occupants can contact the steering wheel or
the instrument panel. Air bags supplement the protection
provided by safety belts. Air bags distribute the force of
the impact more evenly over the occupant's upper body,
stopping the occupant more gradually. But air bags
would not help you in many types of collisions,
including rollovers, rear impacts and side impacts,
primarily because an occupant's motion is not toward
those air bags. Air bags should never be regarded as
anything more than a supplement to safety belts,
and then only in moderate to severe frontal or
near
-frontal collisions.What will you see after an air bag inflates?
After an air bag inflates, it quickly deflates,
so quickly that some people may not even realize
the air bag inflated. Some components of the air bag
module
-- the steering wheel hub for the driver's
air bag, or the instrument panel for the right front
passenger's bag
-- will be hot for a short time.
The parts of the bag that come into contact with you
may be warm, but not too hot to touch. There will be
some smoke and dust coming from vents in the deflated
air bags. Air bag inflation doesn't prevent the driver
from seeing or from being able to steer the vehicle,
nor does it stop people from leaving the vehicle.
CAUTION:
When an air bag inflates, there is dust in the air.
This dust could cause breathing problems
for people with a history of asthma or other
breathing trouble. To avoid this, everyone in the
vehicle should get out as soon as it is safe to do so.
If you have breathing problems but can't get out
of the vehicle after an air bag inflates, then get
fresh air by opening a window or door.

Lap-Shoulder Belt (Extended Cab and Crew Cab)
The positions next to the windows have lap
-shoulder
belts. Here's how to wear one properly.
1. Pick up the latch plate and pull the belt across you.
Don't let it get twisted. The shoulder belt may lock
if you pull the belt across you very quickly. If this
happens, let the belt go back slightly to unlock it.
Then pull the belt across you more slowly.
2. Push the latch plate into the buckle until it clicks.
Pull up on the latch plate to make sure it is secure.
When the shoulder belt is pulled out all the way,
it will lock. If it does, let it go back all the way and
start again.
If the belt is not long enough, see ªSafety Belt
Extenderº at the end of this section.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.

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 fit of the vehicle's safety belt system.
Some booster seats have a shoulder belt positioner,
and some high
-back booster seats have a five-point
harness. A booster seat can also help a child to see out
the window.

1-67
Older Children
Older children who have outgrown booster seats should
wear the vehicle's safety belts.
If you have the choice, a child should sit next to a
window so the child can wear a lap
-shoulder belt and
get the additional restraint a shoulder belt can provide.
Q:What is the proper way to wear safety belts?
A:If possible, 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. It should never be worn over the abdomen,
which could cause severe or even fatal internal
injuries in a crash.
Accident statistics show that children are safer if they
are restrained in the rear seat.
In a crash, children who are not buckled up can strike
other people who are buckled up, or can be thrown
out of the vehicle. Older children need to use safety
belts properly.

Windows
CAUTION:
Leaving children in a vehicle with the windows
closed is dangerous. A child can be overcome by
the extreme heat and can suffer permanent
injuries or even death from heat stroke. Never
leave a child alone in a vehicle, especially with the
windows closed in warm or hot weather.
Manual Windows
Turn the hand crank on each door to raise or lower
manual windows.

2-3
Power Windows (If Equipped)
If your vehicle is equipped
with power windows, the
controls are located on each
of the side doors in the front
and rear.
The driver's door has a switch for the passenger window
as well. Your power windows will work when the
ignition has been turned to ACCESSORY or RUN or
when Retained Accessory Power (RAP) is present.
See ªRetained Accessory Powerº in the Index.
Press the rear of the switch with the power window
symbol on it to lower or raise the window.
The driver's window also has an express down feature
that allows the window to be lowered without holding
the switch. Press and hold the rear of the window switch
for one second to activate the express down mode. The express down mode can be canceled at any time by
pressing the opposite side of the switch. To open the
window partway, lightly tap the switch until the window
is at the desired position.
If you have power windows on a Crew Cab, the driver's
door power window switch has a lockout feature. This
feature prevents the rear windows from operating except
from the driver's position when the driver's door button
labeled WINDOW LOCK is engaged. When the button
is not engaged, the rear power windows will operate.

2-4
Swing-Out Windows (Extended Cab)
To open a rear swing-out
window, flip the latch open
and swing the glass out.
The latch will catch when the window is fully open and
it will also hold it in the open position.
Sliding Rear Window (If Equipped)
To open the sliding rear window, unlock the latch lever
by pushing the lever toward the passenger's side of the
vehicle. Release the lever from the latch plate and slide
the window toward the passenger's side of the vehicle.
To close the window, slide the window toward the driver's
side of the vehicle. The latch lever will automatically snap
on to the latch plate. Try to open the window without
releasing the latch lever to be sure the window is in the
locked position.
