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.
101

The following tips will help you get good starting in
cold weather.
•Use the recommended engine oil when the
outside temperature drops below freezing.
SeeEngine Oil (Caterpillar
®Diesel Engine) on
page 268orEngine Oil (Gasoline Engine)
on page 268orEngine Oil (DURAMAX
®/Isuzu
Diesel Engine) on page 272. When the
outside temperature drops below 0°F (−18°C),
use of the optional engine coolant block
heater is recommended.
•If you experience longer cranking times, notice
an unusual amount of exhaust smoke or are
at higher altitudes (over 7,000 ft. or 2 135 m),
you may use your optional engine coolant
block heater. SeeEngine Coolant Heater on
page 111.
•SeeWhat Fuel to Use on page 253for
information on what fuel to use in cold
weather.
Cold Weather Starting
(Caterpillar®Diesel)
Because the diesel engine uses compression
ignition, it is harder to start in cold weather than a
gasoline engine. The air intake heater and use
of the proper engine oil, optional engine coolant
heaters and optional ether injection systems
help cold weather starting. See the Caterpillar
®
Diesel Engine Operation & Maintenance Manual
for more information.
Restarting the Diesel Engine While
Moving (Automatic Transmission)
If you have to restart the engine while the vehicle
is moving, you will first have to shift to
NEUTRAL (N). This safety feature prevents
starting the engine when the transmission is in a
drive gear for more information.
102

Exhaust Restrictor
(Engine Warm-Up)
Exhaust Restrictor
If your vehicle has a Isuzu 6H or Caterpillar®
Diesel Engine, it may have a feature called
an Exhaust Restrictor (NPE), which uses an air
actuated valve in the exhaust system to restrict
exhaust gas flow which enhances the engine and
heater warm-up.
Automatic Quick Warm-Up
If your vehicle has a DURAMAX®6600 engine, it
has a feature called an Automatic Quick
Warm-Up, which uses the turbocharger to restrict
the exhaust gas flow which enhances the
engine and heater warm-up.
In both systems, exhaust restrictor or automatic
quick warm-up, the cold temperature high
idle feature elevates the engines idle speed, up to
1500 rpm, and restricts the exhaust gas flow,
when outside temperatures are below 32°F (0°C),
and the engine coolant temperature is below
certain levels. This feature enhances heater
performance by raising the engine coolant
temperature faster.For all engines this feature is already turned on.
The automatic quick warm-up on the DURAMAX
®
engine can be turned off and on by doing the
following procedure:
1. Turn the ignition to RUN, with the vehicle off.
2. Press the accelerator pedal to the floor
and hold it while quickly pressing and
fully releasing the brake pedal three times in
less than eight seconds.
3. Release the accelerator pedal and start the
engine. The green exhaust brake/restrictor
light below the radio controls will be lit
for 10 seconds.
If this feature is turned off, by doing the
procedure described previously, and then the
engine is started, the exhaust brake/restrictor
light will flash for 10 seconds and then it
will turn off.
When the engine is started, it will slowly increase to
the high idle speed after a delay of a few seconds;
up to about two minutes. For this method to work
properly there must be no throttle or brake pedal
faults, and the throttle pedal must not fall below
75 percent of wide open throttle while pressing the
brake pedal.
108

Engine Coolant Heater
Your vehicle may be equipped with this feature.
In very cold weather, 0°F (–18°C) or colder,
the engine coolant heater can help. You will get
easier starting and better fuel economy during
engine warm-up. Usually, the coolant heater
should be plugged in a minimum of four hours
prior to starting your vehicle. At temperatures
above 32°F (0°C), use of the coolant heater is
not required.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Find the plug-in outlet located under the
driver’s door.
3. Plug it into a normal, grounded 110-volt AC
outlet.
{CAUTION:
Plugging the cord into an ungrounded
outlet could cause an electrical shock.
Also, the wrong kind of extension cord
could overheat and cause a re. You
could be seriously injured. Plug the cord
into a properly grounded three-prong
110-volt AC outlet. If the cord will not
reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.
4. Before starting the engine, be sure to unplug
and store the cord as it was before to keep it
away from moving engine parts. If you do
not, it could be damaged.
How long should you keep the coolant heater
plugged in? The answer depends on the outside
temperature, the kind of oil you have, and some
other things. Instead of trying to list everything here,
we ask that you contact your dealer in the area
where you will be parking your vehicle. The dealer
can give you the best advice for that particular area.

Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
Be sure to clear as much snow from the rear
window as possible.
Press this button which
is located near the fan
control to turn the rear
window defogger on or
off. An indicator light in
the button will come on
when the rear window
defogger is working.
The rear window defogger will only work when the
ignition is in RUN.
The rear window defogger will turn off several
minutes after the button is pressed. The defogger
can also be turned off by pressing the button
again or by turning off the engine.
Notice:Do not use anything sharp on the
inside of the rear window. If you do, you could
cut or damage the warming grid, and the repairs
would not be covered by your warranty. Do not
attach a temporary vehicle license, tape, a decal
or anything similar to the defogger grid.
Outlet Adjustment
Your vehicle has air outlets on the instrument
panel that allow you to adjust the direction
and amount of airflow inside the vehicle.
Move the lever on the outlet up or down to direct
the airflow. Increase or reduce the amount of
airflow by opening and closing the louvers. The
outlets can be moved side-to-side to direct
the airflow.
Operation Tips
•
Keep the hood and front air inlets free of ice,
snow, or any other obstruction (such as
leaves). The heater and defroster will work far
better, reducing the chance of fogging the
inside of your windows.
•Keep the air path under the front seats clear
of objects. This helps air to circulate
throughout your vehicle.
•Adding outside equipment to the front of your
vehicle, such as hood-air deflectors, may
affect the performance of the heating and air
conditioning system. Check with your
dealer before adding equipment to the outside
of your vehicle.
160

Rear Heating System
If you have a crew cab
and your vehicle has a
rear heater, the
thumbwheel for this
feature is located on
the headliner.
To increase and decrease the flow of heated air to
the rear floor vents, turn the thumbwheel to the
desired fan speed. To turn the fan off, turn
the thumbwheel all the way down.
Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages
that may be on your vehicle. The pictures will
help you locate them.Warning lights and gages can signal that
something is wrong before it becomes serious
enough to cause an expensive repair or
replacement. Paying attention to your warning
lights and gages could also save you or others
from injury.
Warning lights come on when there may be or
is a problem with one of your vehicle’s functions.
As you will see in the details on the next few
pages, some warning lights come on briefly when
you start the engine just to let you know they
are working. If you are familiar with this section,
you should not be alarmed when this happens.
Gages can indicate when there may be or is a
problem with one of your vehicle’s functions. Often
gages and warning lights work together to let you
know when there is a problem with your vehicle.
When one of the warning lights comes on and
stays on when you are driving, or when one of the
gages shows there may be a problem, check
the section that tells you what to do about
it. Waiting to do repairs can be costly and even
dangerous.
161

Wait to Start Indicator
If your vehicle has the DURAMAX®6.6L diesel
engine, it will have glow plugs and an air
intake heater. If your vehicle has the Isuzu 6H
diesel engine, it will have glow plugs and an inlet
heater. If your vehicle has a Caterpillar
®engine,
it will have an inlet heater.
The light in the center of
the instrument panel will
come on when the inlet
heater or glow plugs are
on and the ignition key is
in RUN.
Wait until the indicator light goes off before turning
the ignition key to START.
Malfunction Indicator Lamp
Service Engine Soon Light
If this light comes on or
flashes while you are
driving, two things
may happen.
First, you will not notice any difference in engine
performance, but your tail pipe emissions may
increase. Second, your engine may not run
properly or may stall without warning. If either of
these things happen, drive or tow your vehicle
to your dealer for service.
This light should come on when the ignition is on,
but the engine is not running, as a check to
show you it is working. If it does not come on at
all, have it repaired.
Notice:If you keep driving your vehicle with
this light on, after awhile, your emission
controls may not work as well, your fuel
economy may not be as good, and your engine
may not run as smoothly. This could lead to
costly repairs that may not be covered by your
warranty.
