Servicing Your Airbag-Equipped
Vehicle
Airbags affect how the vehicle should be serviced.
There are parts of the airbag system in several places
around the vehicle. Your dealer/retailer and the
service manual have information about servicing the
vehicle and the airbag system. To purchase a service
manual, seeService Publications Ordering Information
on page 7-10.
{CAUTION:
For up to 10 seconds after the ignition is turned off
and the battery is disconnected, an airbag can still
inflate during improper service. You can be injured
if you are close to an airbag when it inflates. Avoid
yellow connectors. They are probably part of the
airbag system. Be sure to follow proper service
procedures, and make sure the person performing
work for you is qualified to do so.
Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to or change
about the vehicle that could keep the airbags
from working properly?
A:Yes. If you add things that change your vehicle’s
frame, bumper system, height, front end or side
sheet metal, they may keep the airbag system from
working properly. Changing or moving any parts
of the front seats, safety belts, the airbag sensing
and diagnostic module, steering wheel, instrument
panel, front sensors, or airbag wiring can affect
the operation of the airbag system.
If you have any questions about this, you should
contact Customer Assistance before you modify
your vehicle. The phone numbers and addresses
for Customer Assistance are in Step Two of
the Customer Satisfaction Procedure in this manual.
SeeCustomer Satisfaction Procedure on page 7-2.

to Federal Communications Commission (FCC) Rules
and with Industry Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
1. This device may not cause interference.
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
This device complies with RSS-210 of Industry Canada.
Operation is subject to the following two conditions:
1. This device may not cause interference.
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modifications to this system by other than

Remote Keyless Entry (RKE)
System Operation
For vehicles with the Remote Keyless Entry (RKE)
System, transmitter functions work up to 30 feet (9 m)
away from the vehicle.
LOCK:Press to lock all the doors.
UNLOCK:Press once to unlock the driver door.
Press this button again within five seconds to unlock all
the doors. The interior dome lamp comes on for about
40 seconds or until the ignition switch is activated.
Programming Transmitters to the
Vehicle
Only RKE transmitters programmed to the vehicle
will work. If a transmitter is lost or stolen, a replacement
can be purchased and programmed through your
dealer/retailer. When the replacement transmitter is
programmed to the vehicle, all remaining transmitters
must also be programmed. Any lost or stolen transmitters
no longer work once the new transmitter is programmed.
Each vehicle can have up to four transmitters
programmed to it.
Battery Replacement
Notice:When replacing the battery, do not touch
any of the circuitry on the transmitter. Static
from your body could damage the transmitter.
2-4

1. Separate the transmitter with a flat, thin object
inserted into the slot near the key ring hole.
2. Remove the battery.
3. Insert the new battery, positive (+) side down.
Replace with a CR2032 or equivalent battery.4. Align the transmitter back together.
5. Check the operation of the transmitter. If the
transmitter does not work after battery replacement,
it may need to be resynchronized to the vehicle.
SeeResynchronizationfollowing.
Resynchronization
Resynchronization may be necessary due to the
security method used by this system. The transmitter
does not send the same signal twice to the receiver. The
receiver will not respond to a signal it has been sent
previously. This prevents anyone from recording
and playing back the signal from the transmitter.
To resynchronize the transmitter, stand close to the
vehicle and simultaneously press and hold the LOCK
and UNLOCK buttons on the transmitter for at least
five seconds. The door locks should cycle to confirm
resynchronization. If the locks do not cycle, see
your dealer/retailer for service.

Ignition Positions
The ignition switch has five different positions.
A (ACC/ACCESSORY):This position allows you to use
the radio, power windows and the windshield wipers
when the engine is off. To get into ACC/ACCESSORY,
push in the key and turn it toward you. The steering
wheel will remain locked, just as it was before you
inserted the key.
B (LOCK):This position locks the ignition, steering
wheel and transmission. You will only be able to remove
the key when the ignition is turned to LOCK.C (OFF):This position turns off the engine, but leaves
the steering wheel unlocked. Use OFF if you must
have the vehicle in motion while the engine is off.
D (ON/RUN):This position can be used to operate the
electrical accessories and to display some instrument
panel cluster warning and indicator lights. The
switch stays in this position when the engine is running.
If you leave the key in the ACC/ACCESSORY or
ON/RUN position with the engine off, the battery could
be drained. You may not be able to start the vehicle
if the battery is allowed to drain for an extended period
of time.
E (START):This is the position that starts the engine.
When the engine starts, release the key. The ignition
switch returns to ON/RUN for driving.
A warning tone will sound when the driver door is
opened, the vehicle is parked, and the key is in the
ignition.

Moisture will condense in a fuel tank that is almost
empty if the engine has not run for a while, even just
overnight under some conditions. So, it is always best to
refuel the vehicle at the end of each run.
Starting the Diesel Engine
The vehicle’s diesel engine starts differently than a
gasoline engine. Read the following pages to learn how
to start, restart, warm-up, and stop the diesel engine.
The information applies to Caterpillar
®Diesel Engine,
6.6L DURAMAX®Diesel Engine, Isuzu 6H Diesel
Engine, unless otherwise noted.
If you have a Caterpillar
®Diesel Engine, also refer to
the Caterpillar®Diesel Engine Operation & Maintenance
Manual for the starting procedure.
Automatic Transmission
Move the shifter to P (Park) or N (Neutral). The engine
will not start in any other position. To restart the
engine when the vehicle is already moving, use
N (Neutral) only.
Notice:Do not try to shift to P (Park) if the
vehicle is moving. If you do, you could damage
the transmission. Shift to P (Park) only when
the vehicle is stopped.
Manual Transmission
Move the shift lever to N (Neutral) and hold the clutch
pedal to the floor while starting the engine. The vehicle
will not start if the clutch pedal is not all the way down.
Starting the Engine
1. Turn your ignition key to ON/RUN.
Observe the wait to start light. SeeWait to Start
Light on page 3-35. This light may not come
on if the engine is hot.
If you have a Caterpillar
®diesel engine, see your
Caterpillar®Diesel Engine Operation & Maintenance
Manual for proper wait to start light operation.
2. As soon as the wait to start light goes off,
immediately turn the ignition key to START.
When the engine starts, let go of the key.
If the vehicle is equipped with a DURAMAX
®
6600 Diesel Engine, it has a fast warm-up glow
plug system. The wait to start light will illuminate for
a much shorter time than most diesel engines,
due to the rapid heating of the glow plugs.
Notice:Holding the key in START for longer than
15 seconds at a time will cause the battery to
be drained much sooner. And the excessive heat
can damage the starter motor.
2-14

If the Diesel Engine Will Not Start
If you have run out of fuel, seeRunning Out of Fuel on
page 5-17.
If you are not out of fuel, and the engine will not start,
do this:
Turn the ignition key to ON/RUN. Immediately after the
wait to start light goes off, turn the ignition key to START.
If the light does not go off, wait a few seconds, then try
starting the engine again. And, see your dealer/retailer
as soon as you can for a starting system check.
If the light comes on and then goes off and you know
the batteries are charged, but the engine still will
not start, the vehicle needs service.
If the light does not come on when the engine is cold,
the vehicle needs service.If the batteries do not have enough charge to start the
engine, seeBattery on page 5-61.
Be sure you have the right oil for the engine, and that
you have changed the oil at the proper times. If you use
the wrong oil, the engine may be harder to start.
Be sure you are using the proper fuel for existing
weather conditions. SeeWhat Fuel to Use on page 5-8.
If the engine starts, runs a short time, then stops, the
vehicle needs service.
{CAUTION:
Do not use gasoline or starting aids, such as
ether, in the air intake. They could damage the
engine. There could also be a fire, which could
cause serious personal injury.

The ENGINE SHUTDOWN WARNING LIGHT will come
on and a continuous chime will alert the driver
30 seconds before the engine goes into idle shutdown
mode. The engine shutdown warning light and chime will
stay on for the entire duration of the idle shutdown
event to inform the driver that the engine is in idle
shutdown mode. SeeEngine Shutdown Warning Light
on page 3-40for more information.
After the engine shutdown occurs, the engine is no
longer running, and the ignition is still in the ON/RUN
position, all accessories can be used. Turn the ignition
switch to START to restart the engine or turn it to
LOCK or OFF to prevent the battery from draining.High Idle System
High Idle System with Switch
If the vehicle has this
feature, the manual high
idle switch is located in the
instrument panel
switchbank.
