3. Align the covers and snap them together.
4. Check the operation of the transmitter. If the
transmitter does not work after battery
replacement, it may need to be
resynchronized to your vehicle. See
Resynchronizationfollowing.
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 your transmitter, stand close to
your 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 for service.

Notice:Holding your key in START for longer
than 15 seconds at a time will cause your
battery to be drained much sooner. And the
excessive heat can damage your starter motor.
Notice:If the wait to start light stays on
after starting your vehicle, your vehicle may
not run properly. Have your vehicle serviced
right away.
3. If the engine does not start after 15 seconds
of cranking, turn the ignition key to OFF. Wait
one minute for the starter to cool, then try
the same steps again.
If you are trying to start your engine after you
have run out of fuel, seeRunning Out of Fuel
on page 262.
When your engine is cold, let it run for a few
minutes before you move your vehicle. This lets
oil pressure build up. Your engine will sound louder
when it is cold.
Notice:If you are not in an idling vehicle and
the engine overheats, you would not be there to
see the overheated engine indication. This
could damage your vehicle. Do not let your
engine run when you are not in your vehicle.Cold Weather Starting
If your vehicle has the 6.6L DURAMAX®Diesel
Engine and the Isuzu 6H Diesel Engine, the
following notice applies:
Notice:Your diesel engine has an electric air
intake heater system which reduces white
smoke and helps start the engine in cold
weather. Do not spray starting uid into the air
intake where it can contact the heater elements.
If you do not have the GM Automatic Ether
Injection System, do not use starting uid or
you could damage your engine. If you have the
GM system, use only GM approved starting
uid that has been tested to establish
compatibility with the air inlet heater system.

Stopping the Diesel Engine
1. Set the parking brake and shift to
NEUTRAL (N) or PARK (P).
2. Turn the ignition key to OFF.
If your vehicle has a two-speed axle, see
Two-Speed Rear Axle Electric Shift Control on
page 113.
If you have a Caterpillar
®diesel engine, see your
Caterpillar®Diesel Engine Operation &
Maintenance Manual for additional information.
Diesel Engine Warm-Up
Several factors affect how quickly your diesel
engine warms up. These can include outside
temperature, engine load, idle time and your
vehicle’s option content. Your vehicle may be
equipped with some features that can help
the engine reach operating temperature sooner.
Some of these features are discussed below.Also, remember that an automatic transmission
adds heat to the cooling system through the heat
exchanger in the radiator. Because of this,
vehicles equipped with automatic transmissions
are often able to retain engine coolant heat better
than manual transmission vehicles.
See your Caterpillar
®Operation & Maintenance
manual for additional diesel engine warm-up
information.
If Your Diesel Engine Will Not Start
If you have run out of fuel, seeRunning Out of
Fuel on page 262.
If you are not out of fuel, and your engine will not
start, do this:
Turn your ignition key to 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 your engine again. And, see your dealer
as soon as you can for a starting system check.
If the light comes on and then goes off and you
know your batteries are charged, but your engine
still will not start, your vehicle needs service.
103

If the light does not come on when the engine is
cold, your vehicle needs service.
If your batteries do not have enough charge to
start your engine, seeBattery on page 304.
Be sure you have the right oil for your engine, and
that you have changed the oil at the proper
times. If you use the wrong oil, your engine may
be harder to start.
Be sure you are using the proper fuel for existing
weather conditions. SeeWhat Fuel to Use on
page 253.
If the engine starts, runs a short time, then stops,
your vehicle needs service.
{CAUTION:
Do not use gasoline or starting aids, such
as ether, in the air intake. They could
damage your engine. There could also be
a re, which could cause serious personal
injury.
Engine Alarm and Automatic
Shutdown
Your check gages warning light will come on if the
system senses high engine temperature or low
engine oil pressure. If high engine temperature or
low engine oil pressure is detected, you will
also hear a tone alarm at two beats per second.
The alarm and the light will remain on until
the condition is fixed. If the engine temperature or
oil pressure condition worsens, the tone alarm
will go to five beats per second.
If the system senses low engine coolant, the
five beat per second alarm and the low coolant
warning light will come on.
The five beats per second tone alarm means that
your engine will shut down in about 25 to
30 seconds. There is also an engine shutdown
light to indicate that the engine will shut down. See
Engine Shutdown Warning Light on page 177.

•If the engine coolant temperature gage needle
goes into the hot area on the gage, stop the
engine and find the cause of the overheating.
SeeEngine Coolant Temperature Gage on
page 173for more information.
•If you have air brakes, the dual-needle air
pressure gage should read at least 115 psi
(790 kPa) for both service systems before you
try to move the vehicle. When air pressure
is below 60 psi (420 kPa), the LOW AIR light
will come on and you will hear a tone
alarm. SeeBrake System Warning Light on
page 169for more information. If the pressure
does not build up or drops during warm-up,
stop the engine and find the cause before you
try to move the vehicle. Recommended air
pressure before driving is 120 psi (830 kPa).
SeeAir Pressure Gage on page 183for
more information.
•The charging system light should come on
when the ignition key is turned to RUN or
START and should go out when the engine is
running above idle. If the light does not go
out or comes back on during normal engine
operation, have the charging system checked
right away. (This light tells you if thegenerator is not charging; it does not reflect
the condition of the battery.) SeeCharging
System Light on page 167for more
information.
•The voltmeter charge indicator gage tells you
the condition of your battery’s charge. The
gage should be in the center area during
engine operation. The red area on the
left indicates an undercharge condition; the
red area on the right indicates an overcharge.
If the gage is in either red area, have the
battery and charging system checked
right away. SeeVoltmeter Gage on page 168
for more information.
Notice:Do not allow the engine to operate at
low idle for more than ve minutes. This
can cause low engine operating temperatures
which can affect engine operation and
reduce engine life. Engine idle speed should
be increased to 1200 rpm whenever extended
idle is required. Once started, the engine
should be placed under load to allow the
engine coolant temperature to reach 150°F
(66°C) before shutting off the engine.

If your vehicle has
four-wheel drive, the
transfer case knob
is located to the right of
the steering wheel
on the instrument panel.
Use this knob to shift
into and out of
four-wheel drive.
An indicator light shows you which position the
transfer case is in. The indicator lights come
on briefly when you turn on the ignition and
one stays on. If the lights do not come on, you
should take your vehicle to your dealer for service.
An indicator light flashes while shifting the
transfer case. It will remain on when the shift is
complete. If for some reason the transfer
case cannot make a requested shift, it returns to
the last chosen setting.Recommended Transfer Case Settings

Airbag Readiness Light
If your vehicle has airbags, there is an airbag
readiness light on the instrument panel, which
shows the airbag symbol. The system checks the
airbag’s electrical system for malfunctions. The
light tells you if there is an electrical problem. The
system check includes the airbag sensors, the
airbag modules, the wiring, the passenger airbag
suppression circuit and the crash sensing and
diagnostic module. For more information on
the airbag system, seeAirbag System on page 68.
This light will come on
when you start your
vehicle, and it will flash
for a few seconds.
Then the light should go
out. This means the
system is ready.
If the airbag readiness light stays on after you
start the vehicle or comes on when you are driving,
your airbag system may not work properly.
Have your vehicle serviced right away.The airbag readiness light should flash for a few
seconds when you turn the ignition key to RUN or
START. If the light doesn’t come on then, have
it fixed so it will be ready to warn you if there is a
problem.
{CAUTION:
If the airbag readiness light stays on after
you start your vehicle, it means the airbag
system may not be working properly. The
airbags in your vehicle may not inate in
a crash, or they could even inate without
a crash. To help avoid injury to yourself
or others, have your vehicle serviced right
away if the airbag readiness light stays on
after you start your vehicle.
