During this warm-up period, check the 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 3-38for
more information.
•If the engine coolant temperature gage needle goes
into the hot area on the gage, stop the engine and
find the cause of the overheating. SeeEngine
Coolant Temperature Gage on page 3-34for more
information.
•If you have air brakes, the dual-needle air pressure
gage should read at least 115 psi (790 kPa) for both
service systems before you try to move the vehicle.
When air pressure is below 60 psi (420 kPa), the
LOW AIR light will come on and you will hear a
tone alarm. SeeBrake System Warning Light on
page 3-31for more information. If the pressure does
not build up or drops during warm-up, stop the
engine and find the cause before you try to move the
vehicle. Recommended air pressure before driving is
120 psi (830 kPa). SeeAir Pressure Gage on
page 3-47for more information.
•The charging system light should come on when the
ignition key is turned to ON/RUN or START and
should go out when the engine is running above idle.
If the light does not go out or comes back on during
normal engine operation, have the charging system
checked right away. (This light tells you if the
generator is not charging; it does not reflect the
condition of the battery.) SeeCharging System Light
on page 3-29for more information.
•The voltmeter charge indicator gage tells you the
condition of the battery’s charge. The gage should be
in the center area during engine operation. The red
area on the left indicates an undercharge condition;
the red area on the right indicates an overcharge.
If the gage is in either red area, have the battery and
charging system checked right away. SeeVoltmeter
Gage on page 3-30for more information.
Notice:Do not allow the engine to operate at low
idle for more than five minutes. This can cause low
engine operating temperatures which can affect
engine operation and reduce engine life. Engine idle
speed should be increased to 1200 rpm whenever
extended idle is required. Once started, the engine
should be placed under load to allow the engine
coolant temperature to reach 150°F (66°C) before
shutting off the engine.

Locking Hubs
Turn the dial of the hublock (A) from the FREE position
to the LOCK position to lock the front axle.
Turn the dial of the hublock (A) from the LOCK position
to the FREE position to unlock the axle.
You do not have to back the vehicle up to disengage
the hublocks.If the vehicle has
four-wheel drive, the
transfer case knob is
located to the right of the
steering wheel on the
instrument panel. Use this
knob to shift into and
out of four-wheel drive.
An indicator light shows you which position the transfer
case is in. The indicator lights come on briefly when
you turn on the ignition and one stays on. If the lights do
not come on, you should take the vehicle to your
dealer/retailer for service. An indicator light flashes while
shifting the transfer case. It will remain on when the
shift is complete. If for some reason the transfer case
cannot make a requested shift, it returns to the last
chosen setting. Hublock Dial Location

Shifting Out of Four-Wheel Low
To shift from Four-Wheel Low to Four-Wheel High or
Two-Wheel High, the vehicle must be stopped or moving
less than 3 mph (5 km/h) with the transmission in
N (Neutral) with the engine running. The preferred
method for shifting out of Four-Wheel Low is to have
the vehicle moving 1 or 2 mph (1.6 to 3.2 km/h).
Turn the knob to Four-Wheel High or Two-Wheel High.
You must wait for the Four-Wheel High or Two-Wheel
High indicator light to stop flashing and remain on before
shifting the transmission into gear.
Notice:Shifting the transmission into gear before
the Four-Wheel High or Two-Wheel High indicator
light has stopped flashing could damage the transfer
case. To help avoid damaging the vehicle, always
wait for the Four-Wheel High or Two-Wheel High
indicator light to stop flashing before shifting
the transmission into gear.
If the knob is turned to Four-Wheel High or Two-Wheel
High while the vehicle is in gear and/or moving, the
Four-Wheel High or Two-Wheel high indicator light
flashes for 30 seconds. It will not complete the shift
unless the vehicle is moving less than 3 mph (5 km/h)
with the transmission in N (Neutral).
Shifting Into Neutral
Before shifting the transfer case to N (Neutral), first
make sure the vehicle is parked so that it will not roll.
1. Set the parking brake. SeeParking Brake (With
Hydraulic Brakes) on page 2-38orParking Brake
(With Air Brakes) on page 2-41for parking
brake apply procedure.
2. Start the vehicle.
3. Put the transmission in N (Neutral).
4. Shift the transfer case to Two-Wheel High.
5. Turn the transfer case knob all of the way past
Four-Wheel Low and hold it there for a minimum
of 10 seconds. The N (Neutral) indicator light
comes on.
6. Shift the transmission to R (Reverse) for
one second, then shift the transmission to D (Drive)
for one second.
7. Turn the ignition to OFF.
8. Place the transmission shift lever in P (Park).
9. Turn the ignition to LOCK.

Shifting Out of Neutral
To shift the transfer case out of N (Neutral), do the
following:
1. Set the parking brake. SeeParking Brake (With
Hydraulic Brakes) on page 2-38orParking Brake
(With Air Brakes) on page 2-41for parking
brake apply procedure.
2. Apply the regular brake pedal.
3. Turn the ignition to ON/RUN with the engine off.
4. Put the transmission in N (Neutral).
5. Turn the transfer case knob to the desired shift
position (Two-Wheel High, Four-Wheel High,
Four-Wheel Low).
6. After the transfer case has shifted out of N (Neutral),
the indicator light goes out.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Verify that
the parking brake is fully released and the brake
warning light is off before driving.
7. Release the parking brake.
8. Start the engine and shift the transmission lever to
the desired position.Excessively shifting the transfer case into or out of the
different modes can cause the transfer case to enter the
shift protection mode. This protects the transfer case from
possible damage and only allows the transfer case to
respond to one shift per 10 seconds. The transfer case
can stay in this mode for up to three minutes.
Parking
{CAUTION:
If you do not park the vehicle properly, it can roll.
If you have left the engine running, it can move
very quickly. You or others could be injured. To be
sure the vehicle will not move, even when you are
on level ground, follow the steps below.

Page 103 of 376
{CAUTION:
It can be dangerous to get out of the vehicle
without the parking brake firmly set. The vehicle
can roll. If you have left the engine running, the
vehicle can move suddenly. You or others could
be injured. To be sure the vehicle will not move,
even when you are on fairly level ground, always
set the parking brake.
To set the hand lever parking brake, hold the regular
brake pedal down, then pull up on the handle, until
it stops.

Using Cruise Control on Hills
How well the cruise control works on hills depends upon
the vehicles speed, load and the steepness of the hills.
When going up steep hills, you may want to step on the
accelerator pedal to maintain your speed. When going
downhill, you may have to brake or shift to a lower gear to
keep your speed down. When the brake or clutch is
applied the cruise control will shut off.
For vehicles with the exhaust brake option and the
exhaust brake is turned on, the exhaust brake may come
on and try to slow down the vehicle to the set cruise
control speed if the vehicle has accelerated past the set
cruise control speed while going downhill.
Ending Cruise Control
There are four different ways to turn off the cruise
control:
•Step lightly on the brake pedal (manual and
automatic transmissions).
•Press the clutch pedal to the floor (manual
transmissions).
•Move the cruise switch to9.
•Shift the transmission to N (Neutral).
Erasing Speed Memory
The cruise control set speed memory is erased when
the ignition is turned off.

Exterior Lamps
The control located to the left of the steering column
operates the exterior lamps.
The exterior lamp control has three positions:
OFF:Turns off all lamps except the Daytime Running
Lamps (DRL).
;(Parking Lamps):Turns on the parking lamps,
together with the following:
•Marker Lamps
•Taillamps
•License Plate Lamps
•Instrument Panel Lights
O(Headlamps):Turns on the headlamps, together
with the previously listed lamps and lights.
Change the headlamps from low to high beam by
pulling the turn signal/multifunction lever toward you.
Pull the lever toward you again to return to low beam.
A circuit breaker protects the headlamps. If there is
an electrical overload, the headlamps will flicker on and
off. Have the headlamp wiring checked right away if
this ever happens.
Headlamps on Reminder
For vehicles with this system, a tone will sound when
the headlamps and/or parking lamps are turned on and
the ignition is in LOCK/OFF or ACC/ACCESSORY.

Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the
day. Fully functional daytime running lamps are required
on all vehicles first sold in Canada.
The DRL system will make the headlamps come on
at reduced brightness when the following conditions
are met:
•The ignition is on,
•the exterior lamp control is off, and
•the parking brake is released.
When the DRL are on, only the headlamps will be on.
The taillamps, sidemarker, instrument panel lights,
and other lamps will not be on.When it gets dark, the
DRL indicator light is a
reminder to turn the
headlamps on.
When the headlamps are turned on, the other lamps
that come on with the headlamps will be on.
When the headlamps are turned off, the regular lamps
will go off, and the low-beam headlamps will change
to the reduced brightness of DRL.
To idle the vehicle with the DRL off, set the parking
brake. The DRL will stay off until the parking brake is
released.
Turn on the regular headlamp system when it is
needed.
