•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 173for 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 169for 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 183for
more information.
•The charging system light should come on
when the ignition key is turned to 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 thegenerator is not charging; it does not reflect
the condition of the battery.) SeeCharging
System Light on page 167for more
information.
•The voltmeter charge indicator gage tells you
the condition of your 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 168
for more information.
Notice:Do not allow the engine to operate at
low idle for more than ve 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.

Parking
{CAUTION:
If you do not park your 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 your
vehicle will not move, even when you are
on level ground, follow the steps below.
Parking a Vehicle With the Two-Speed
Rear Axle
1. With the engine running, shift the two-speed
rear axle into low. To be sure it is in low, you
will need to move the vehicle in gear just a little.
2. Hold the regular brake pedal down with your
right foot.
3. Apply the parking brake.
4. Shift the transmission to NEUTRAL for
manual transmission or PARK (P) for
automatic transmission.
Parking Brake (With Hydraulic
Brakes)
If your vehicle has hydraulic brakes, it has either a
parking brake foot pedal or hand lever. If you
have the parking brake foot pedal, it is located
below the instrument panel to the left of the
steering column.
If you have the parking brake hand lever, it is
located to the right of the driver, on the floor.
Parking Brake Hand Lever Shown
125

To set the foot pedal parking brake, hold the
regular brake pedal down with your right foot. Push
down the parking brake pedal with your left foot.
To set the hand lever parking brake, hold the
regular brake pedal down with your right foot. Pull
up on the handle with your right hand, until it stops.
If the ignition is on when the parking brake is set,
the brake system warning light will come on.
To release the foot pedal parking brake, hold
the regular brake pedal down. Pull the brake
release handle, located just above the parking
brake pedal, to release the parking brake.
To release the hand lever parking brake, hold the
regular brake pedal down and push down on
the handle until it stops.
If the ignition is on when the parking brake is
released, the brake system warning light will
go off.Parking Brake (with Air Brakes)
If your vehicle has
air brakes, you will
have this parking brake.
It is located above
the radio in the
instrument panel.
Pulling it out applies the parking brake. The
parking brake light will come on when the air
parking brake is applied.
126

For driving with a trailer, the yellow and red, if
equipped, knobs must be pushed in. When you are
not pulling a trailer, the red trailer air supply
knob must be pulled out.
{CAUTION:
If you apply any one of the air brake
parking controls while the vehicle is
moving, your rig will stop suddenly. If you
are not ready for this, you or others could
be injured. Do not apply any one of these
controls while you are driving, unless you
have to make an emergency stop.
If the air pressure drops below 60 to 70 psi
(413 to 482 kPa), the primary brake light and
warning buzzer will come on. If the air pressure
drops to 35 to 45 psi (241 to 310 kPa), the
red trailer air supply knob will automatically pop
out and apply the spring brakes on the trailer.If the air pressure drops to 35 to 45 psi
(241 to 310 kPa), the yellow park brake knob will
automatically pop out and apply the spring
brakes on the truck or tractor.
If you ever have a complete loss of air so that
your air brakes automatically apply, there is a way
that the tow operator can release the parking
brakes to tow the vehicle. SeeTowing Your
Vehicle on page 241.
Parking Brake Burnish Procedure
All vehicles which have hydraulic brakes will have
a parking brake. It is recommended that the
parking brake be burnished as part of the new
vehicle break-in. The parking brake will work best
after it has been burnished following these
instructions:
1. Making sure that there is no other traffic
around, get the vehicle speed up to
20 mph (32 km/h) and pull up to apply the
parking brake. Let the vehicle come to
a complete stop. Apply the base brakes and
disengage the parking brake.

With cruise control, you can maintain a speed
of about 25 mph (40 km/h) or more without
keeping your foot on the accelerator. Cruise
control does not work at speeds below about
25 mph (40 km/h).
If you have an automatic transmission and you
apply your brakes, the cruise control will shut off.
If you have a manual transmission and you
apply your brakes or push the clutch pedal, the
cruise control will shut off.
{CAUTION:
Cruise control can be dangerous where
you cannot drive safely at a steady speed.
So, do not use your cruise control on
winding roads or in heavy traffic.
Cruise control can be dangerous on
slippery roads. On such roads, fast
changes in tire traction can cause
excessive wheel slip, and you could lose
control. Do not use cruise control on
slippery roads.
Setting Cruise Control
{CAUTION:
If you leave your cruise control on when
you are not using cruise, you might hit a
button and go into cruise when you do not
want to. You could be startled and even
lose control. Keep the cruise control switch
off until you want to use cruise control.
1. Move the cruise control switch to on.
2. Get up to the speed you want.
3. Press in the set button at the end of the lever
and release it.
4. Take your foot off the accelerator pedal. The
accelerator pedal will not go down.
147

Notice:If you continue driving your vehicle
after the transmission warning light comes on,
you could damage the transmission. While
this light is on, the transmission cannot
operate in all gears. If you attempt to shift
gears, the vehicle may not continue to move.
Do not attempt to shift gears while the
transmission warning light is on. Instead, drive
directly to an authorized dealer for service. If
you cannot drive to a dealer immediately, have
the vehicle towed.
Range Inhibit Warning Indicator
If your vehicle has an Allison 1000/2200/2300/
2500 series automatic transmission, a lighted bar
under the current gear selected will flash.
If your vehicle has an Allison 3000/3500
series automatic transmission, the current gear
selected on the pushbutton display will flash.
The flashing bar or gear selection indicates that
transmission range shifts may not occur.
For detailed information on shift inhibit limitations,
see the Allison Automatic Transmission
Operator’s Manual in your vehicle for further
information.
Brake System Warning Light
Your vehicle has either hydraulic or air brakes.
Each system has different warning lights.
Hydraulic Brake System
Warning Lights
Vehicles with hydraulic brake systems
have two brake system warning lights on the
instrument panel.
If the brake system
warning light comes on,
it means that the
fluid level in the master
cylinder reservoir is
low or there is another
problem with your
hydraulic brakes.
When it comes on, you will also hear a
warning tone.
169

The brake system warning light may come on, and
the warning tone may sound, when you are
turning and braking at the same time. This is
normal. See “Hydraulic Brake Systems” under
Braking on page 210.
This light is located
above the climate
controls in the center of
the instrument panel.
If the service brakes soon warning light comes on,
it means there may be something wrong in the
brake system.
When this light comes on, you will also hear a
warning tone. Have the system repaired
immediately.Both of these lights should come on briefly every
time you start your engine. If they do not come
on then, have them fixed so they will be ready to
warn you if there is a problem. If one or both
of these warning lights stay on after you start the
engine, there could be a brake problem. Have
your brake system inspected right away.
If one or both of these lights come on while you
are driving, pull off the road and stop carefully. You
may notice that the pedal is harder to push, or
the pedal may go closer to the floor. It may take
longer to stop. If this light is still on, have the
vehicle towed for service. SeeTowing Your
Vehicle on page 241. See “Hydraulic Brake
Systems” underBraking on page 210for further
information.
170

Anti-Lock Brake System
Warning Light
This light will come on
briefly when you start
your engine, then
it will turn off. This
is normal.
If the light stays on, or comes on when you are
driving, your vehicle needs service. If the BRAKE
or LOW AIR warning light is not on, you still
have brakes, but you do not have the anti-lock
brake feature. If the BRAKE and/or LOW AIR
warning light is on, you do not have anti-lock
brakes and there is a problem with your regular
brakes. SeeBrake System Warning Light on
page 169andAnti-Lock Brake System (ABS) on
page 212for more information.
The anti-lock brake system warning light should
come on briefly when you turn the ignition
key to ON. If the light does not come on then,
have it fixed so it will be ready to warn you if
there is a problem.
Trailer Anti-Lock Brake System
Warning Light
This light is located
above the climate
controls in the center of
the instrument panel.
If your vehicle is connected to a trailer with
anti-lock brakes, this light should come on briefly,
as a check, when you turn on the ignition.
When this light comes on and stays on, it means
there is something wrong in the trailer anti-lock
brake system. Have the system repaired
immediately.
If an anti-lock brake system equipped trailer is not
connected, this light is not functional.
