Air Bag Systems
This part explains the air bag systems.
Your vehicle has air bags – one air bag for the driver and
another air bag for the right front passenger. Your vehicle
may also have roof-mounted side impact air bags; one for
the driver and the passenger directly behind the driver
and one for the right front passenger and the person
seated directly behind that passenger.
Air bags are designed to help reduce the risk of injury
from the force of an in ating air bag. But these air bags
must in ate very quickly to do their job and comply
with federal regulations.Here are the most important things to know about the
air bag system:
{CAUTION:
You can be severely injured or killed in a crash
if you are not wearing your safety belt – even if
you have air bags. Wearing your safety belt
during a crash helps reduce your chance of
hitting things inside the vehicle or being
ejected from it. Air bags are “supplemental
restraints” to the safety belts. All air bags are
designed to work with safety belts but do not
replace them.

CAUTION: (Continued)
Frontal air bags for the driver and right front
passenger are designed to deploy only in
moderate to severe frontal and near frontal
crashes. They are not designed to in ate in
rollover, rear or low-speed frontal crashes, or
in many side crashes. And, for some
unrestrained occupants, frontal air bags may
provide less protection in frontal crashes than
more forceful air bags have provided in the
past. The roof-mounted side impact air bags
are designed to in ate only in moderate to
severe crashes where something hits the side
of your vehicle. They are not designed to
in ate in frontal, in rollover or in rear crashes.
Everyone in your vehicle should wear a safety
belt properly — whether or not there is an air
bag for that person.
{CAUTION:
Both frontal and side impact air bags in ate
with great force, faster than the blink of an
eye. If you’re too close to an in ating air bag,
as you would be if you were leaning forward, it
could seriously injure you. Safety belts help
keep you in position for air bag in ation before
and during a crash. Always wear your safety
belt even with frontal air bags. The driver
should sit as far back as possible while still
maintaining control of the vehicle. Occupants
should not lean on or sleep against the door.

If your vehicle has a roof-mounted side impact air bag
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 side impact air bag
for the right front passenger and the person seated
directly behind that passenger, it is located in the ceiling
above the side windows.

{CAUTION:
If something is between an occupant and an
air bag, 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 air bag must be kept clear. Do not put
anything between an occupant and an air bag,
and do not attach or put anything on the
steering wheel hub or on or near any other air
bag covering. If your vehicle has side impact
air bags, never secure anything to the roof of
your vehicle by routing the rope or tiedown
through any door or window opening. If you
do, the path of an in ating side impact air bag
will be blocked. The path of an in ating air bag
must be kept clear.
When Should an Air Bag In ate?
The driver’s and right front passengers frontal air bags
are designed to deploy only in moderate to severe
frontal, or near-frontal crashes. But they are designed to
in ate only if the impact speed is above the system’s
designed “threshold level.”
In addition, your vehicle has “dual stage” frontal air
bags, which adjust the amount of restraint according to
crash severity. For moderate frontal impacts, these
air bags in ate at a level less than full deployment. For
more severe frontal impacts, full deployment occurs.
If the front of your vehicle goes straight into a wall that
doesn’t move or deform, the threshold level for the
reduced deployment is about 12 to 16 mph
(19.3 to 26 km/h), and the threshold level for a full
deployment is about 20 to 24 mph (32.2 to 38.5 km/h).
The threshold level can vary, however, with speci c
vehicle design, so that it can be somewhat above
or below this range.
If your vehicle strikes something that will move or
deform, such as a parked car, the threshold level will be
higher. The driver’s and right front passenger’s frontal
air bags are not designed to in ate in rollovers, rear
impacts, or in many side impacts because in ation
would not help the occupant.

In many crashes severe enough to in ate an air bag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from the
right front passenger air bag.
Air bags are designed to in ate only once. After an
air bag in ates, you will need some new parts for
your air bag system. If you do not get them, the air
bag system will not be there to help protect you
in another crash. A new system will include air bag
modules and possibly other parts. The service
manual for your vehicle covers the need to replace
other parts.
Your vehicle is equipped with electronic frontal
sensors which help the sensing system distinguish
between a moderate and a more severe frontal
impact. If your vehicle has side impact air bags, it
also has electronic side sensors. Your vehicle
is equipped with a crash sensing and diagnostic
module, which records information about the air bag
system. The module records information about
the readiness of the system and when the system
commands air bag in ation. It records the status
of the driver’s safety belt usage in a crash in which
the air bag deploys or a crash in which the air
bag nearly deploys. The module also records speed,
engine rpm, brake and throttle data.
Let only quali ed technicians work on your air bag
system. Improper service can mean that your air
bag system will not work properly. See your dealer
for service.
Notice:If you damage the covering for the driver’s
or the right front passenger’s air bag, or the side
impact air bag covering on the ceiling near the side
windows, the bag may not work properly. You
may have to replace the air bag module in the
steering wheel, both the air bag module and
the instrument panel for the right front passenger’s
air bag, or side impact air bag module and ceiling
covering for the roof-mounted side impact air
bag. Do not open or break the air bag coverings.

Assist Handles
Your vehicle may have assist handles to be used when
getting out of your vehicle. If your vehicle has assist
handles, they may be located above the front passenger
door if you have a regular cab, or above the front and
rear passenger doors if you have an extended cab
or crew cab.
If your vehicle is equipped with roof-mounted side
impact air bags, there will be assist handles located
above both the driver’s and front passenger’s doors.
Rear Storage Area
If your vehicle is an extended cab model, it may be
equipped with storage compartments under the
rear seats.
Bed Rails
{CAUTION:
If your vehicle has bed rails, they are there for
appearance only. If you try to tie down a load
with them, or to secure things in your truck,
not only can it damage the bed rails, but the
load can loosen. This could cause injury to
you or others. Secure loads by using the cargo
tie-down loops, inside the truck bed area.

Before You Go Off-Roading
There are some things to do before you go out. For
example, be sure to have all necessary maintenance
and service work done. Check to make sure all
underbody shields (if so equipped) are properly
attached. Be sure you read all the information about
your four-wheel-drive vehicle in this manual. Is
there enough fuel? Is the spare tire fully in ated? Are
the uid levels up where they should be? What are the
local laws that apply to off-roading where you will be
driving? If you do not know, you should check with law
enforcement people in the area. Will you be on
someone’s private land? If so, be sure to get the
necessary permission.
Loading Your Vehicle for Off-Road
Driving
There are some important things to remember about
how to load your vehicle.
The heaviest things should be on the load oor and
forward of your rear axle. Put heavier items as far
forward as you can.
Be sure the load is secured properly, so driving on
the off-road terrain does not toss things around.
{CAUTION:
Cargo on the load oor piled higher than
the seatbacks can be thrown forward
during a sudden stop. You or your
passengers could be injured. Keep cargo
below the top of the seatbacks.
Unsecured cargo on the load oor can be
tossed about when driving over rough
terrain. You or your passengers can be
struck by ying objects. Secure the
cargo properly.
Heavy loads on the roof raise the vehicle’s
center of gravity, making it more likely to
roll over. You can be seriously or fatally
injured if the vehicle rolls over. Put heavy
loads inside the cargo area, not on the
roof. Keep cargo in the cargo area as far
forward and low as possible.
