Vehicle Damage Warnings
Also, in this manual you will find these notices:
Notice:These mean there is something that could
damage your vehicle.
A notice tells about something that can damage the
vehicle. Many times, this damage would not be covered
by your vehicle’s warranty, and it could be costly. But
the notice will tell 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.
There are also warning labels on the vehicle. They use
the same words, CAUTION or NOTICE.
Vehicle Symbols
The vehicle has components and labels that use
symbols instead of text. Symbols 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

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
in ated for the load you are carrying.
If you have a Caterpillar®diesel engine, see the
Caterpillar®Diesel Engine Operation and
Maintenance Manual.
2-11
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 is 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 does not lock the
steering wheel like LOCK. Use OFF if you must have
your vehicle in motion while the engine is off.
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 the Gasoline Engine
Engines start differently. The 8th digit of your Vehicle
Identification Number (VIN) shows the code letter for your
engine. SeeVehicle Identi cation Number (VIN) on
page 5-87. Follow the proper steps to start the engine.
To start a diesel engine, seeStarting the 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
will not start in any other position — that is a safety
feature.
Manual Transmission
Set the parking brake, shift to neutral NEUTRAL (N)
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 does not 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 will not 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. Any resulting damage
would not be covered by your vehicle’s warranty.
If you ever need to have your vehicle towed,
seeTowing Your Vehicle on page 4-35.
2-13
Gasoline Engine Warm-Up
When you have 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 2 to 3 miles
(3.2 to 4.8 km), especially in cold weather. SeeHigh
Idle System (Caterpillar
®Diesel/Gasoline Engine)
on page 2-19.
Restarting the Gasoline 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.
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 and 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 is always best
to refuel your vehicle at the end of each run.
Starting the Diesel Engine
Your vehicle’s diesel engine starts differently than a
gasoline engine. Read the following pages to learn how
to start, restart, warm-up, and stop your diesel engine.
The information applies to both Caterpillar
®diesel
engine and DURAMAX®diesel engine unless
otherwise noted.
If you have a Caterpillar
®diesel engine, also refer to
your Caterpillar®diesel engine Operation & Maintenance
Manual for the starting procedure.
2-14
Automatic Transmission
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine will not start in any other position — that is
a safety feature. To restart when you are already
moving, use NEUTRAL (N) only.
Notice:Do not try to shift to PARK (P) if your
vehicle is moving. If you do, you could damage the
transmission. Shift to PARK (P) only when your
vehicle is stopped.
Manual Transmission
Move your shift lever to NEUTRAL and hold the
clutch pedal to the floor while starting the engine.
Your vehicle will not start if the clutch pedal is not
all the way down — that is a safety feature.
Starting Your Engine
1. Turn your ignition key to RUN.
Observe the wait to start light. SeeWait to
Start Indicator (Diesel Engine) on page 3-36.
This light may not come on if the engine is hot.
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 your vehicle is equipped with a DURAMAX
®6600
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 plug system.
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.
2-15
If you are trying to start your engine after you have run
out of fuel, seeRunning Out of Fuel on page 5-15.
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 DURAMAX®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.
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 5-22or
Engine Oil (DURAMAX®Diesel) on page 5-22or
Engine Oil (Gasoline Engine) on page 5-26.
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 2-24.
•SeeWhat Fuel to Use on page 5-8for information
on what fuel to use in cold weather.
