2-16 Engine Starter Over-Crank Protection
(If Equipped)
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. See ªVehicle Identification Numberº in
the Index. Follow the proper steps to start the engine.
To start a diesel engine, see ªStarting Your Diesel
Engineº in the Index.
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.

2-21 Engine Alarm and Automatic Shutdown
(If Equipped)
Your check gages 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 approximately 25
-30 seconds.
There is also an engine shutdown light to indicate that
the engine will shut down. See ªAutomatic Engine
Shutdown Lightº later in this section.
Pull off the road and shut off the engine. Don't start it
until the reason for the problem is known, and the
problem is fixed. If the engine shuts down when you are
still in traffic, you can restart the engine and get another
25
-30 seconds of operation. Do this only if you have to,
since there is a problem that can harm the engine if it
isn't fixed. Engine automatic shutdown, for gasoline
engines, requires activation by your dealer.
High Idle System (Caterpillar
Diesel
and Gasoline Engines)
Your vehicle has both automatic and manual high idle
capabilities.
Automatic High Idle System (Diesel Engines)
(If Equipped)
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.
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 ten minutes.

The brake pedal is pressed.

The manual transmission clutch pedal is pressed or,
the automatic transmission (if equipped) is shifted
from NEUTRAL (N) or PARK (P).

The vehicle speed exceeds approximately
5 mph (8 km/h).

The throttle is pressed.

2-51 Windshield Washer
(Washer Fluid): There is a paddle marked
with the windshield washer symbol at the top of the
multifunction lever. To spray washer fluid on the
windshield, press the paddle. The wipers will clear
the window and then either stop or return to your preset
speed.
CAUTION:
In freezing weather, don't use your washer until
the windshield is warmed. Otherwise the washer
fluid can form ice on the windshield, blocking
your vision.
Cruise Control (Option)
If your vehicle has this
feature, it is located at
the end of your
multifunction lever.
(Set): Pressing in this button at the end of the
lever sets the cruise control speed.
(Off): Moving the switch to this position turns off
the cruise control.
| (On): Moving the switch to this position turns on
the cruise control.
+(Resume/Accelerate): Moving the switch to this
position turns on resume/accelerate.

2-53
Resuming a Set Speed
Suppose you set your cruise control at a desired speed
and then you apply the brake. This, of course, shuts off
the cruise control. But you don't need to reset it.
Once you're going about 30 mph (48 km/h) or more,
you can move the cruise control switch briefly from on
to resume/accelerate.
The vehicle will return to your chosen speed and
stay there.
If you hold the switch at resume/accelerate, the vehicle
will keep going faster until you release the switch or
apply the brake. So unless you want to go faster, don't
hold the switch at resume/accelerate.Increasing Speed While Using Cruise Control
There are two ways to go to a higher speed:

Use the accelerator pedal to get to the higher speed.
Press the button at the end of the lever, then release
the button and the accelerator pedal. You'll now
cruise at the higher speed.

Move the cruise switch from on to
resume/accelerate. Hold it there until you get up
to the speed you want, and then release the switch.
To increase your speed in very small amounts,
move the switch briefly to resume/accelerate.
Each time you do this, your vehicle will go about
1 mph (1.6 km/h) faster.

2-71 Speedometer and Odometer
Your speedometer lets you see your speed in both miles
per hour (mph) and kilometers per hour (km/h).
Your odometer shows how far your vehicle has been
driven, in either miles (used in the United States) or
kilometers (used in Canada).Trip Odometer
The trip odometer can tell you how far your vehicle has
been driven since you last set the trip odometer to zero.
While the engine is running, press the reset button,
located to the right of the trip odometer, to toggle
between the trip odometer and the regular odometer.
Holding the reset button for two seconds while the
engine is running and the trip odometer is displayed,
will reset it.
To display the odometer reading with the ignition off,
press the reset button.

2-88 Change Oil Light
The change oil light should
come on briefly as a bulb
check when you start the
engine. If the light doesn't
come on, have it serviced.
If the change oil soon light comes on and stays on after
you start the engine, have the oil changed.
For additional information, see ªEngine Oil, When to
Changeº in the Index. To reset the change oil light, see
ªGM Oil Life System
º in the Index.
Low Oil Level Light
This light should come on
as a check, when you start
your engine. If the light
fails to come on, have it
repaired as soon as possible
so you will be aware when
the oil level is low.
If this light comes on and stays on, it means your engine
is low on oil. You need to check the oil level right away.
See ªChecking Engine Oilº in the Index for further
information.

2-94 Air Pressure Gage (If Equipped)
If your vehicle has air
brakes, the air pressure gage
is located above the
switchbank in the center of
the instrument panel.
This gage shows the air pressure for both your front and
rear brake systems.
If the needle on the gage indicates that the air pressure is
below 60 to 75 psi (415 to 517 kPa), the low air warning
light will come on. An alarm will also sound if this
happens.
The yellow pointer shows the pressure available for the
front system, while the green pointer shows pressure for
the rear. There should be no more than 4 psi (28 kPa)
difference showing between the systems.
Don't drive until both pointers are showing at least
115 psi (793 kPa), so you'll have enough air if you
need to apply your brakes.
Air Filter Restriction Indicator (Option)
This optional gage is
located above the
switchbank in the center
of the instrument panel.
It monitors the engine
air filter.
As the filter gets dirty, the yellow indicator will begin to
rise. When it reaches 25 inches of vacuum on the scale,
the filter should be replaced.
After replacing the filter, reset the gage by pressing in
the yellow reset button at the bottom of the gage.
If you have a diesel engine, also see your Caterpillar


Operation & Maintenance Manual.
