Key In the Ignition
Never leave your vehicle with the keys inside, as it
is an easy target for joy riders or thieves. If you
leave the key in the ignition and park your vehicle,
a chime will sound, when you open the driver’s
door. Always remember to remove your key from
the ignition and take it with you. This will lock
your ignition and transaxle. Also, always remember
to lock the doors.
The battery could be drained if you leave the
key in the ignition while your vehicle is parked.
You may not be able to start your vehicle after it has
been parked for an extended period of time.
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
The 8th digit of your Vehicle Identification
Number (VIN) shows the code letter for your
engine. Use this number to verify the type of
engine in your vehicle. SeeVehicle Identication
Number (VIN) on page 340. Follow the proper steps
to start the engine.
To start a diesel engine, seeStarting the Diesel
Engine on page 100.
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.
97

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. See
High Idle System on page 106.
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.
99

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 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 your Caterpillar®Diesel Engine Operation &
Maintenance Manual for the starting procedure.
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 on page 174. 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 your 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 plug system.
100

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

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

High Idle System
High Idle System with Switch
If your vehicle has this
feature, the manual high
idle switch is located
in the instrument panel
switchbank.
This system can be used to increase your engine
idle speed whenever the following conditions
are met:
•The brake pedal is not pressed.
•The vehicle speed is below about 5 mph
(8 km/h) for vehicles with diesel engines. The
vehicle must not be moving and the
accelerator must not be pressed for vehicles
with gasoline engines.
•If the vehicle has manual transmission the
clutch pedal is not pressed or, if the vehicle
has the automatic transmission it is in
NEUTRAL (N) or PARK (P).
The manual high idle feature is activated by
pressing the switch on the instrument panel. When
the switch is pressed again, or any of the
previous conditions are not met, manual high idle
will be deactivated.
The manual high idle has been preset at the
factory. Your dealer may change the setting to fit
your needs.
For vehicles with Caterpillar
®diesel engines, the
high idle switch can be used to set any desired
high idle speed.
106

To set a new temporary engine idle speed do the
following:
1. Make sure all of the previously described
conditions are met.
2. Press the accelerator pedal to the desired
engine speed.
3. Momentarily press the manual high idle
switch.
The temporary high idle speed will be set. This
new high idle rpm level will be remembered by the
system until either the ignition is turned to OFF
or a new high idle speed is set.
Automatic High Idle System
The automatic high idle feature will engage
whenever you start your vehicle and the engine is
below the preset operating temperature. This
will help decrease engine warm-up time.On vehicles that have the Caterpillar
®diesel
engine you may have an exhaust restrictor that
will operate in High Idle mode. The exhaust brake
switch must be on for this feature to operate.
SeeDiesel Engine Exhaust Brake on page 112for
more information.
Idle speed will then return to normal under any of
the following conditions:
•The engine reaches the preset operating
temperature or has been operating for at least
10 minutes.
•The brake pedal is pressed.
•The manual transmission clutch pedal is
pressed or, if the vehicle has automatic
transmission, it is shifted from NEUTRAL (N)
or PARK (P).
•The vehicle speed exceeds about 5 mph
(8 km/h).
•The throttle is pressed.
107

The engine idle speed will return to normal once
the following conditions are met:
•Once engine coolant temperature reaches
about 150°F (65°C).
•The intake temperature reaches a
certain level.
The high idle speed will be temporarily interrupted
and the engine speed will return to normal if
any of the following conditions occur:
•The brake pedal is applied.
•The accelerator pedal is pressed.
•The automatic transmission is shifted out of
PARK (P) or NEUTRAL (N).
•The clutch pedal on the manual transmission
is pressed.
•Vehicle speed is detected.
Once these conditions no longer exist, the engine
idle speed will slowly increase to high idle after
the normal delay, if the conditions for engine
coolant temperature and air intake temperature
are still met.
Engine Checks Before Operating
When you have started your engine, let it run for
20 to 30 seconds before you put a load on the
engine. But do not leave the vehicle while
the engine is running.
Avoid unnecessary idling of diesel engine
equipped vehicles.
If the engine idles too long, the temperature of the
engine coolant will fall below the normal operating
range. Low engine operating temperature
causes several conditions which affect engine
operation and reduce engine life.
The engine should be permitted to go through a
warm-up period. Operate the vehicle at a minimum
of 600 rpm during the warm-up period. During
this period and during operation, the following
observations should be made.
During this warm-up period, check your warning
lights and gages:
•If oil pressure does not begin to rise within
15 seconds of starting, stop the engine
and find the cause. SeeOil Pressure Gage on
page 175for more information.
109

Diesel Engine Exhaust Brake
If your vehicle has a Isuzu 6H or Caterpillar®
Diesel Engine, it may have an exhaust brake,
which is located in the exhaust system.
If your vehicle has a 6.6L DURAMAX
®6600
Diesel Engine, it may have an exhaust brake,
which is controlled through the turbocharger.
The exhaust brake for both engines operates
the same.
The exhaust brake
switch is located in the
instrument panel
switchbank.
Push the bottom of the switch to turn the exhaust
brake on. When you push the top of the switch,
the exhaust brake will turn off.
There is an indicator light on the instrument panel
similar to the symbol on the switch, that will come
on when the exhaust brake is active. SeeExhaust
Brake Indicator Light on page 178for more
information.When using the exhaust brake, the proper gear
range selection is important. The exhaust brake will
be most effective if the gear range selected is the
lowest possible range that does not allow the
engine rpm to go more than 200 rpm above rated
(full load) rpm. If you have a Caterpillar®Diesel
Engine, do not exceed 2900 rpm. If you have a
Isuzu 6H Diesel engine, do not exceed 2550 rpm.
If you have a DURAMAX
®6600 Diesel Engine, do
not exceed 3600 rpm.
If your vehicle has an Allison
®
1000/2200/2300/2500 series automatic
transmission and press this button, the
transmission will downshift to a factory default
setting of third gear. To change the default setting,
or for more information on factory default
settings, contact your dealer for assistance.
The accelerator and clutch pedals must be
released in order for the exhaust brake to engage.
The exhaust brake will automatically shut off
when the anti-lock brake system is active.
If your vehicle has a Caterpillar
®Diesel Engine or
a DURAMAX®6600 Diesel Engine, the exhaust
brake will become active in cruise control
when you exceed the set speed by 3 to 5 mph.
