Advanced Front Air Bags are designed to provide addi-
tional protection by supplementing the seat belts in
certain frontal collisions depending on several factors,
including the severity and type of collision. Advanced
Front Air Bags are not expected to reduce the risk of
injury in rear, rollover, or side collisions.
The Advanced Front Air Bags will not deploy in all
frontal collisions, including some that may produce sub-
stantial vehicle damage — for example, some pole colli-
sions, truck underrides, and angle offset collisions. On
the other hand, depending on the type and location of
impact, Advanced Front Air Bags may deploy in crashes
with little vehicle front-end damage but that produce a
severe initial deceleration.
The side air bags will not deploy in all side collisions.
Side air bag deployment will depend on the severity and
type of collision.Because air bag sensors measure vehicle deceleration
over time, vehicle speed and damage by themselves are
not good indicators of whether or not an air bag should
have deployed.
Seat belts are necessary for your protection in all colli-
sions, and also are needed to help keep you in position,
away from an inflating air bag.
The ORC monitors the readiness of the electronic parts of
the air bag system whenever the ignition switch is in the
START or ON/RUN position. If the key is in the LOCK
position, in the ACC position, or not in the ignition, the
air bag system is not on and the air bags will not inflate.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 71
Maintaining Your Air Bag System
WARNING!
•Modifications to any part of the air bag system
could cause it to fail when you need it. You could
be injured if the air bag system is not there to
protect you. Do not modify the components or
wiring, including adding any kind of badges or
stickers to the steering wheel hub trim cover or the
upper right side of the instrument panel. Do not
modify the front bumper, vehicle body structure, or
add aftermarket side steps or running boards.
• It is dangerous to try to repair any part of the air
bag system yourself. Be sure to tell anyone who
works on your vehicle that it has an air bag system.
(Continued)
WARNING! (Continued)
•Do not attempt to modify any part of your air bag
system. The air bag may inflate accidentally or may
not function properly if modifications are made.
Take your vehicle to an authorized dealer for any
air bag system service. If your seat, including your
trim cover and cushion, needs to be serviced in any
way (including removal or loosening/tightening of
seat attachment bolts), take the vehicle to your
authorized dealer. Only manufacturer approved
seat accessories may be used. If it is necessary to
modify the air bag system for persons with dis-
abilities, contact your authorized dealer.
80 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
Air Bag Warning Light
You will want to have the air bags ready to
inflate for your protection in a collision. The
Air Bag Warning Light monitors the internal
circuits and interconnecting wiring associated
with air bag system electrical components. While the air
bag system is designed to be maintenance free, if any of
the following occurs, have an authorized dealer service
the air bag system immediately.
• The Air Bag Warning Light does not come on during
the four to eight seconds when the ignition switch is
first turned to the ON/RUN position.
• The Air Bag Warning Light remains on after the four to
eight-second interval.
• The Air Bag Warning Light comes on intermittently or
remains on while driving. NOTE:
If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant Restraint
Controller (ORC) may also be disabled. The air bags may
not be ready to inflate for your protection. Promptly
check the fuse block for blown fuses. Refer to the label
located on the inside of the fuse block cover for the
proper air bag fuses. See your authorized dealer if the
fuse is good.
Event Data Recorder (EDR)
This vehicle is equipped with an event data recorder (EDR).
The main purpose of an EDR is to record, in certain crash or
near crash-like situations, such as an air bag deployment or
hitting a road obstacle, data that will assist in understanding
how a vehicle’s systems performed. The EDR is designed to
record data related to vehicle dynamics and safety systems
for a short period of time, typically 30 seconds or less. The
EDR in this vehicle is designed to record such data as:
• How various systems in your vehicle were operating;

driving, have the system inspected at an authorized
dealer as soon as possible. Refer to “Occupant Restraints”
in “Things To Know Before Starting Your Vehicle” for
further information.
10. Oil Pressure Gauge — If EquippedThe pointer should always indicate some oil pres-
sure when the engine is running. A continuous high or
low reading under normal driving conditions may indi-
cate a lubrication system malfunction. Immediate service
should be obtained from an authorized dealer.
11. Speedometer
The speedometer shows the vehicle speed in miles per
hour and/or kilometers per hour (mph/km/h).
12. Park/Headlight ON Indicator — If Equipped
This indicator will illuminate when the park
lights or headlights are turned on. 13. Cargo Light — If Equipped
The cargo light will illuminate when the cargo
light is activated by pressing the cargo light
button on the headlight switch.
14. Fuel Gauge
Shows level of fuel in tank when ignition switch is in the

15. Vehicle Security Light — If Equipped This light will flash at a fast rate for approxi-
mately 15 seconds, when the vehicle security
alarm is arming, and then will flash slowly
until the vehicle is disarmed.
16. Tire Pressure Monitoring Telltale Light
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended

mation.
Shifting Procedure
NOTE:
•
If any of the requirements to select a new transfer case
position have not been met, the transfer case will not shift.
The position indicator light for the previous position will
remain ON and the newly selected position indicator light
will continue to flash until all the requirements for the
selected position have been met. To retry a shift: return
the control knob back to the original position, make
certain all shift requirements have been met, wait five
seconds and try the shift again.
• If all the requirements to select a new transfer case
position have been met, the current position indicator
light will turn OFF, the selected position indicator light
will flash until the transfer case completes the shift.
When the shift is complete, the position indicator light
for the selected position will stop flashing and remain
ON.
2WD To 4WD LOCK
Rotate the 4WD control switch to the desired position.
Shifts between 2WD and 4WD LOCK can be done with
the vehicle stopped or in motion. With the vehicle in
motion, the transfer case will engage/disengage faster if
you momentarily release the accelerator pedal after turn-
ing the control switch. If the vehicle is stopped, the
ignition switch must be in the ON position with the
engine either running or off. This shift cannot be com-
pleted if the ignition switch is in the ACC position.
