Vehicle Damage Warnings
Also, in this book you will find these notices:
Notice:These mean there is something that could
damage your vehicle.
A notice will tell you about something that can damage
your vehicle. Many times, this damage would not be
covered by your warranty, and it could be costly. But the
notice will tell you what to do to help avoid the
damage.
When you read other manuals, you might see
CAUTION and NOTICE warnings in different colors
or in different words.
You’ll also see warning labels on your vehicle. They use
the same words, CAUTION or NOTICE.
Vehicle Symbols
Your vehicle has components and labels that use
symbols instead of text. Symbols, used on your vehicle,
are shown along with the text describing the operation
or information relating to a specific component, control,
message, gage or indicator.
If you need help figuring out a specific name of a
component, gage or indicator, reference the following
topics:
•Seats and Restraint Systems in Section 1
•Features and Controls in Section 2
•Instrument Panel Overview in Section 3
•Climate Controls in Section 3
•Warning Lights, Gages and Indicators in Section 3
•Audio System(s) in Section 3
•Engine Compartment Overview in Section 5

•Your vehicle is equipped with a crash sensing and
diagnostic module, which records information
about the air bag system. The module records
information about the readiness of the system, when
the system commands air bag inflation.
The module also records speed, engine rpm, brake
and throttle data.
•Let only qualified technicians work on your air bag
systems. Improper service can mean that an air
bag system won’t work properly. See your dealer for
service.
Notice:If you damage the covering for the driver’s
or the right front passenger’s air bag, the bag
may not work properly. You may have to replace the
air bag module in the steering wheel or both the
air bag module and the instrument panel for
the right front passenger’s air bag. Do not open or
break the air bag coverings.
Air Bag Off Switch
If your vehicle has a right front passenger air bag, it has
a switch on the instrument panel that you can use to
turn off the right front passenger’s air bag.

Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an elaborate
“break-in.” But it will perform better in the long run
if you follow these guidelines:
Let your engine warm up before you operate
your vehicle under load.
Keep your speed at 55 mph (88 km/h) or less for
the rst 500 miles (805 km).
Do not drive at any one speed — fast or
slow — for the rst 500 miles (805 km). Do not
make full-throttle starts.
Avoid making hard stops for the rst 200 miles
(322 km) or so. During this time your new
brake linings are not yet broken in. Hard stops
with new linings can mean premature wear
and earlier replacement. Follow this breaking-in
guideline every time you get new brake
linings.
Use the lowest gear you can when you start a
loaded vehicle in motion and when going up
hills to avoid overloading the engine.
Check and adjust engine and transmission uid
levels often and be sure tires are properly
inated for the load you are carrying.
If you have a Caterpillar®diesel engine, see the
Caterpillar®Diesel Engine Operation and
Maintenance Manual.

Ignition Positions
With your key in the ignition switch, you can turn it to
five different positions.
A (ACCESSORY):This position allows you to use
things like the radio, power windows and the windshield
wipers when the engine is off. To get into ACCESSORY,
push in the key and turn it toward you. Your steering
wheel will remain locked, just as it was before you
inserted the key.
B (LOCK):This position locks your ignition, steering
wheel and transmission. It’s a theft-deterrent feature.
You will only be able to remove your key when the
ignition is turned to LOCK.C (OFF):This position lets you turn off the engine but
still turn the steering wheel. It doesn’t lock the
steering wheel like LOCK. Use OFF if you must have
your vehicle in motion while the engine is off (for
example, if your vehicle is being pushed).
D (RUN):This is the position for driving.
E (START):This position starts your engine.
Engine Starter Over-Crank Protection
Your vehicle may have an engine starter over-crank
protection system. If the starter motor overheats
and shuts off due to over-cranking, the motor must cool
down before it will reset and allow starter operation.
It can take up to six minutes before the starter will
work again.
Starting Your Gasoline Engine
Engines start differently. The 8th digit of your Vehicle
Identification Number (VIN) shows the code letter
for your engine. SeeVehicle Identication Number (VIN)
on page 5-85. Follow the proper steps to start the
engine.
To start a diesel engine, seeStarting Your Diesel
Engine on page 2-14.
2-12

Automatic Transmission
Set the parking brake and move your shift lever to
NEUTRAL (N) or PARK (P) if so equipped. Your engine
won’t start in any other position – that’s a safety
feature.
Manual Transmission
Set the parking brake, shift to neutral and hold the
clutch pedal to the floor while starting the engine.
Starter Motor Operation
•The starter motor will disengage if you release the
key or the engine reaches a predetermined engine
speed.
•To prevent overheating, the starter motor will
disengage after continuously operating for
15 seconds. You must release the key from the
start position to re-engage the starter.
•The starter motor will not engage if the engine is
already running.
•The starter motor will disengage if, after two
seconds, the starter pinion gear does not engage
the flywheel or there is no engine rpm signal
from the engine speed sensor.
Starting Your Engine
1. Without pushing the accelerator pedal, turn your
ignition key to START. When the engine starts, let
go of the key. The idle speed will go down as
your engine gets warm.
2. If the engine doesn’t start in 10 seconds, push the
accelerator pedal all the way down and crank the
engine for five more seconds, unless it starts
sooner.
3. If your engine still won’t start (or starts but then
stops), it could be flooded with too much gasoline.
Wait 15 seconds to let the starter motor cool
down. Do Steps 1 through 3 again.
When the engine starts, let go of the key and the
accelerator pedal.
Notice:Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer. If you do not, your engine
might not perform properly.
If you ever need to have your vehicle towed, see
Towing Your Vehicle on page 4-31.
2-13

Gasoline Engine Warm-Up
When you’ve started your engine, let it run for
20 or 30 seconds to warm up before you put a load on
the engine.
Drive at moderate speeds for the first few miles,
especially in cold weather. Running a cold engine at
high speed can damage it. SeeHigh Idle Systemunder
Starting Your Diesel Engine on page 2-14
Restarting the Gasoline Engine While
Moving (Automatic Transmission)
If you have to restart the engine while the vehicle is
moving, you’ll first have to shift the automatic
transmission to NEUTRAL (N). This safety feature
prevents starting the engine when the transmission is in
a drive gear.
Stopping the Gasoline Engine
Let your engine idle for a few seconds before turning it
off after you have finished driving your vehicle.
If you shift to NEUTRAL (N) or PARK (P), set the
parking brake.
If your vehicle has a two-speed axle, put the range
selector in LOW. To be sure the axle has shifted into
LOW, engage the clutch and transmission; the vehicle
may move slightly when you do this.While your engine is idling before you turn it off, you
can make a list of any operational or handling concerns
to give to responsible maintenance personnel so
they can handle them right away.
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’s always best to
refuel your vehicle at the end of each run.
Starting Your Diesel Engine
If you have a Caterpillar®diesel engine, also refer to
your Caterpillar®Diesel Engine Operation &
Maintenance Manual for starting procedure.
For vehicles with the DURAMAX™ diesel engine, also
seeStarting Your DURAMAX™ Diesel Engine on
page 2-19.
To make starting easier in cold weather (below 32°F or
0°C), the proper viscosity engine oil should be used.
SeeEngine Oil (Caterpillar
®Diesel Engine) on
page 5-20orEngine Oil (Gasoline Engine) on page 5-20
orEngine Oil (DURAMAX™ Diesel) on page 5-25. It’s
also best to heat the engine oil first. You can do this by
using an engine coolant heater.
If you ever need to have your vehicle towed, see
Towing Your Vehicle on page 4-31.
2-14

Restarting the Diesel Engine While
Moving (Automatic Transmission)
If you have to restart the engine while the vehicle is
moving, you’ll first have to shift the automatic
transmission to NEUTRAL (N). This safety feature
prevents starting the engine when the transmission is in
a drive gear.
Stopping the Diesel Engine
If you have a Caterpillar®diesel engine, see your
Caterpillar®Diesel Engine Operation & Maintenance
Manual.
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 2-26.
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.
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.
