How does the side airbag system work?
The design and development of the
side airbag system included
recommended testing procedures
that were developed by a group of
automotive safety experts known as
the Side Airbag Technical Working
Group. These recommended testing
procedures help reduce the risk of
injuries related to the deployment of
side airbags.
The side airbag system consists of
the following:
•An inflatable bag (airbag) with a
gas generator concealed behind
the outboard bolster of the driver
and front passenger seatbacks.
•A special seat cover designed to
allow airbag deployment.
•The same warning light, electronic control and diagnostic unit as used
for the front airbags.
•Crash sensors located on the front doors.
•One crash sensor located on each side of the c-pillar (Crew cab and
SuperCab only).
Side airbags, in combination with safety belts, can help reduce the risk of
severe injuries in the event of a significant side impact collision.
The side airbags are fitted on the outboard side of the seatbacks of the
front seats. In certain lateral collisions, the airbag on the side affected by
the collision will be inflated. The airbag was designed to inflate between
the door panel and occupant to further enhance the protection provided
occupants in side impact collisions.
The airbag SRS is designed to activate when the vehicle sustains lateral
deceleration sufficient to cause the sensors to close an electrical circuit
that initiates airbag inflation.
The fact that the airbags did not inflate in a collision does not mean that
something is wrong with the system. Rather, it means the forces were
not of the type sufficient to cause activation. Side airbags are designed

WARNING:All occupants of the vehicle including the driver
should always wear their safety belts even when an airbag SRS
and Safety CanopySystem is provided.
WARNING:To reduce risk of injury, do not obstruct or place
objects in the deployment path of the inflatable Safety Canopy.
How does the Safety CanopySystem work?
The design and development of the
Safety Canopysystem included
recommended testing procedures
that were developed by a group of
automotive safety experts known as
the Side Airbag Technical Working
Group. These recommended testing
procedures help reduce the risk of
injuries related to the deployment of
side airbags (including the Safety
Canopy).
The Safety CanopySystem consists
of the following:
•An inflatable curtain with a gas
generator concealed behind the
headliner between the A and C
pillar.
•A headliner designed to flex open
above the side doors to allow Safety Canopydeployment.
•The same warning light, electronic control and diagnostic unit as used
for the front airbags.
•Two crash sensors located on the C-pillar (one on each side)
(SuperCab and Crew Cab only).
•Crash sensors located on the front doors.
•Rollover sensor in the restraints control module (RCM).
The Safety CanopySystem, in combination with safety belts, can help
reduce the risk of severe injuries in the event of a significant side impact
collision or rollover event.

Determining if the system is operational
The SRS uses a readiness light in the instrument cluster or a tone to
indicate the condition of the system. Refer toWarning lights and
chimesin theInstrument Clusterchapter. Routine maintenance of the
side airbag is not required.
A difficulty with the system is indicated by one or more of the following:
•The readiness light (same light as for front airbag system) will either
flash or stay lit.
•The readiness light will not illuminate immediately after ignition is
turned on.
•A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and/or light are repaired.
If any of these things happen, even intermittently, have the SRS serviced
at your authorized dealer immediately. Unless serviced, the system may
not function properly in the event of a collision.
SOS Post-Crash Alert System™
The system automatically flashes the turn signal lamps and sounds the
horn three times at four second intervals in the event of a serious impact
that deploys an airbag (front, side, side curtain or Safety Canopy)or
the safety belt pretensioners.
The system can be turned off when any one of the following actions are
taken by the driver or any other person:
•pressing the hazard control button,
•or pressing the panic button on the remote entry transmitter.
The feature will continue to operate until the vehicle runs out of power.

Passenger airbag ON/OFF switch (if equipped)
WARNING:An airbag
ON/OFF switch may be
installed in this vehicle. Before
driving,alwayslook at the face of
the switch to be sure the switch is
in the proper position in
accordance with these instructions
and warnings. Failure to put the
switch in a proper position can
increase the risk of serious injury
or death in a collision.
Turning the passenger airbag off
1. Insert the ignition key, turn the
switch to OFF position and hold in
the OFF position while removing the
key.
2. When the ignition is turned to the
on position the “pass airbag off”
light illuminates briefly, momentarily
shuts off and then turns back on.
This indicates that the passenger
airbag is deactivated.
WARNING:If the light fails to illuminate when the passenger air
bag switch is in the OFF position and the ignition switch is in
on, have the passenger air bag switch serviced at your authorized
dealer immediately.
WARNING:In order to avoid inadvertent activation of the
switch, always remove the ignition key from the passenger air
bag ON/OFF switch.
WARNING:An infant in a rear-facing seat faces a high risk of
serious or fatal injuries from a deploying passenger airbag. Rear
facing infant seats should NEVER be placed in the front seats, unless
the passenger airbag is turned off.

Turning the passenger airbag back on
The passenger airbag remains off until you turn it back on.
1. Insert the ignition key and turn
the switch to ON.
2. The “pass airbag off” light will
briefly illuminate when the ignition
is turned to on. This indicates that
the passenger airbag is operational.
WARNING:If the “pass airbag off” light is illuminated when the
passenger airbag switch is in the ON position and the ignition
switch is in on, have the passenger airbag switch serviced at your
authorized dealer immediately.
The passenger side airbag should always be ON (the “pass airbag off”
light shouldnotbe illuminated) unless the passenger is a person who
meets the requirements stated either in Category 1, 2 or 3 of the
NHTSA/Transport Canada deactivation criteria which follows.
WARNING:The safety belts for the driver and right front
passenger seating positions have been specifically designed to
function together with the airbags in certain types of crashes. When
you turn OFF your airbag, you not only lose the protection of the
airbag, you also may reduce the effectiveness of your safety belt
system, which was designed to work with the airbag. If you are not a
person who meets the requirements stated in the NHTSA/Transport
Canada deactivation criteria turning OFF the airbag can increase the
risk of serious injury or death in a collision.
WARNING:If your vehicle has rear seats, always transport children
who are 12 and younger in the rear seat. Always use safety belts
and child restraints properly. DO NOT place a child in a rear facing infant
seat in the front seat unless your vehicle is equipped with an airbag
ON/OFF switch and the passenger airbag is turned OFF. This is because
the back of the infant seat is too close to the inflating airbag and the risk
of a fatal injury to the infant when the airbag inflates is substantial.

5. Put the safety belt in the
automatic locking mode. To do so,
grasp the shoulder portion of the
belt and pull downward until all of
the belt is pulled out.
6. Allow the belt to retract to remove slack. The belt will click as it
retracts to indicate it is in the automatic locking mode.
7. Try to pull the belt out of the retractor to make sure the retractor is
in the automatic locking mode (you should not be able to pull more belt
out). If the retractor is not locked, repeat Steps 5 and 6.
8. Remove remaining slack from the
belt. Force the seat down with extra
weight, e.g., by pressing down or
kneeling on the child restraint while
pulling up on the shoulder belt in
order to force slack from the belt.
This is necessary to remove the
remaining slack that will exist once
the additional weight of the child is
added to the child restraint. It also
helps to achieve the proper
snugness of the child seat to the
vehicle. Sometimes, a slight lean
towards the buckle will additionally
help to remove remaining slack from the belt.

•Narrower — to provide greater
maneuverability in tight spaces,
particularly in off-road use.
As a result of the above dimensional
differences, SUV’s and trucks often
will have a higher center of gravity
and a greater difference in center of
gravity between the loaded and
unloaded condition.
These differences that make your
vehicle so versatile also make it
handle differently than an ordinary
passenger car.

TIRES
Tires are designed to give many thousands of miles of service, but they
must be maintained in order to get the maximum benefit from them.
Glossary of tire terminology
•Tire label:A label showing the OE (Original Equipment) tire sizes,
recommended inflation pressure and the maximum weight the vehicle
can carry.
•Tire Identification Number (TIN):A number on the sidewall of
each tire providing information about the tire brand and
manufacturing plant, tire size and date of manufacture. Also referred
to as DOT code.
•Inflation pressure:A measure of the amount of air in a tire.
•Standard load:A class of P-metric or Metric tires designed to carry a
maximum load at 35 psi [37 psi (2.5 bar) for Metric tires]. Increasing
the inflation pressure beyond this pressure will not increase the tire’s
load carrying capability.
•Extra load:A class of P-metric or Metric tires designed to carry a
heavier maximum load at 41 psi [43 psi (2.9 bar) for Metric tires].
Increasing the inflation pressure beyond this pressure will not increase
the tire’s load carrying capability.
•kPa:Kilopascal, a metric unit of air pressure.
•PSI:Pounds per square inch, a standard unit of air pressure.
•Cold inflation pressure:The tire pressure when the vehicle has
been stationary and out of direct sunlight for an hour or more and
prior to the vehicle being driven for 1 mile (1.6 km).
•Recommended inflation pressure:The cold inflation pressure found
on the Safety Compliance Certification Label or Tire Label located on
the B-Pillar or the edge of the driver’s door.
•B-pillar:The structural member at the side of the vehicle behind the
front door.
•Bead area of the tire:Area of the tire next to the rim.
•Sidewall of the tire:Area between the bead area and the tread.
•Tread area of the tire:Area of the perimeter of the tire that
contacts the road when mounted on the vehicle.
•Rim:The metal support (wheel) for a tire or a tire and tube assembly
upon which the tire beads are seated.

under-inflation of the tires, improper tires (load range, size, or type), or
vehicle modifications such as lift-kits. In the event that your vehicle
experiences shimmy, you should slowly reduce speed by either lifting off
the accelerator pedal or lightly applying the brakes. The shimmy will
cease as the vehicle speed decreases.
Maximum Permissible Inflation Pressureis the tire manufacturer’s
maximum permissible pressure and/or the pressure at which the
maximum load can be carried by the tire. This pressure is normally
higher than the manufacturer’s recommended cold inflation pressure
which can be found on the Safety Compliance Certification Label or Tire
Label which is located on the B-Pillar or the edge of the driver’s door.
The cold inflation pressure should never be set lower than the
recommended pressure on the Safety Compliance Certification Label or
Tire Label.
When weather temperature changes occur, tire inflation pressures also
change. A 10°F (6°C) temperature drop can cause a corresponding drop
of 1 psi (7 kPa) in inflation pressure. Check your tire pressures
frequently and adjust them to the proper pressure which can be found
on the Safety Compliance Certification Label or Tire Label.
To check the pressure in your tire(s):
1. Make sure the tires are cool, meaning they are not hot from driving
even a mile.
If you are checking tire pressure when the tire is hot, (i.e. driven more
than 1 mile [1.6 km]), never “bleed” or reduce air pressure. The tires are
hot from driving and it is normal for pressures to increase above
recommended cold pressures. A hot tire at or below recommended cold
inflation pressure could be significantly under-inflated.
Note:If you have to drive a distance to get air for your tire(s), check
and record the tire pressure first and add the appropriate air pressure
when you get to the pump. It is normal for tires to heat up and the air
pressure inside to go up as you drive.
2. Remove the cap from the valve on one tire, then firmly press the tire
gauge onto the valve and measure the pressure.
3. Add enough air to reach the recommended air pressure.
Note:If you overfill the tire, release air by pushing on the metal stem in
the center of the valve. Then recheck the pressure with your tire gauge.
4. Replace the valve cap.
5. Repeat this procedure for each tire, including the spare.
