Water in fuel (if equipped)
During refueling it is possible for
water-contaminated diesel fuel to be
pumped into your fuel tank. Your
vehicle fuel system is equipped with
a fuel filter/water separator to
remove water from the fuel. The
indicator light illuminates when the fuel filter/water separator has a
significant quantity of water, or when the ignition key is switched to the
START position. If the light illuminates when the engine is running, stop
the vehicle as soon as safely possible, shut off the engine and drain the
filter bowl. Allowing water to stay in the system could result in extensive
damage to, or failure of, the fuel injection system.
To drain the fuel filter/water separator (refer toMaintenance and
Specificationschapter for procedure). Rotate the valve at the bottom of
the filter assembly allowing water to drain from the system. Close the
valve upon completion.
Do not drain water separator while engine is running. Fuel may
ignite if separator is drained while engine is running or vehicle is
moving.
Air clean warning (if equipped)
Illuminates when the air system is
restricted (dirty, clogged).
Turn signal
Illuminates when the left or right
turn signal or the hazard lights are
turned on. If one or both of the
indicators stay on continuously or
flash faster, check for a burned-out
turn signal bulb. Refer toExterior bulbsin theLightschapter.

CASSETTE AND CASSETTE PLAYER CARE
²Use only cassettes that are 90 minutes long or less.
²Do not expose tapes to direct sunlight, high humidity, extreme heat or
extreme cold. Allow tapes that may have been exposed to extreme
temperatures to reach a moderate temperature before playing.
²Tighten very loose tapes by inserting a finger or pencil into the hole
and turning the hub.
²Remove loose labels before inserting tapes.
²Do not leave tapes in the cassette player for a long time when not
being played.
RADIO FREQUENCY INFORMATION
The Federal Communications Commission (FCC) and the Canadian Radio
and Telecommunications Commission(CRTC) establish the frequencies
AM and FM stations may use for their broadcasts. Allowable frequencies
are:
AM 530, 540±1600, 1610 kHz
FM 87.7, 87.9±107.7, 107.9 MHz
Not all frequencies are used in a given area.
RADIO RECEPTION FACTORS
Three factors can affect radio reception:
²Distance/strength.The further an FM signal travels, the weaker it is.
The listenable range of the average FM station is approximately 40 km
(24 miles). This range can be affected by ªsignal modulation.º Signal
modulation is a process radio stations use to increase their
strength/volume relative to other stations.
²Terrain.Hills, mountains and tall buildings between your vehicle's
antenna and the radio station signal can cause FM reception problems.
Static can be caused on AM stations by power lines, electric fences,
traffic lights and thunderstorms. Moving away from an interfering
structure (out of its ªshadowº) returns your reception to normal.
²Station overload.Weak signals are sometimes captured by stronger
signals when you pass a broadcast tower. A stronger signal may
temporarily overtake a weaker signal and play while the weak station
frequency is displayed.

INTERIOR LAMPS
Map lamps (if equipped)
To turn on the map lamps, press the
control next to each lamp.
EXTERIOR BULBS
Check operation of lamps, safety equipment and warning signals
It is a good safety practice to check operation of headlamps, parking
lamps, turn signals, clearance and marker lamps, instrument panel and
control lamps each day.

monitor on the shift pad will display N (Neutral) when the ignition key is
turned to the ON position.
Allison 2000 series
These transmissions have no P (Park) position. Before leaving
the driver's seat, always shift into N (Neutral) and set the
parking brake. Shut off the engine and remove your ignition key.
Always use wheel chocks for hilly or off-road parking. Unexpected and
possibly sudden vehicle movement may occur if these precautions are
not taken.
This transmission provides five forward speeds in four ranges and one
reverse range.
R (Reverse)
Use this position to back the vehicle. Completely stop the vehicle before
shifting from R (Reverse) to any forward gear (1, 2, 4 or D). The reverse
warning signal will sound when the selector is in R (Reverse). Reverse
has only one gear and provides the greatest gear reduction.
N (Neutral)
Place the selector in N (Neutral) before starting the engine. Shift to N
(Neutral) and set the parking brake any time the engine is to be running
while the operator is not at the controls. The engine should be at idle
speed when any shift from N (Neutral) to a drive range is made.
Do not allow your vehicle to coast in N (Neutral). Engine
braking is not available in N (Neutral). Allowing your vehicle to
coast in N (Neutral) may result in loss of vehicle control and severe
internal transmission damage.
D (Drive-Normal driving position)
In this position, the transmission starts in first gear and automatically
shifts through second, third, fourth and fifth depending on load and
speed demands. When the vehicle is slowing down, the transmission will
automatically downshift. This range is used for highway driving under
normal conditions.

4 and 2 (Fourth and Second)
Use these ranges when road, load or traffic conditions require a lower
gear. These ranges provide greater engine braking than D (Drive). When
conditions are improved that no longer require these lower gears, shift
back to D (Drive).
1 (First)
The transmission has to be manually shifted into 1 (First) and will not
shift into a higher gear. Use this position when pulling through mud or
snow, driving up steep grades, hauling extra heavy loads or where
maximum reduction is required.
Allison 2400 series
This transmission provides five forward speeds in four ranges and one
reverse range.
P (Park)
Use this position when you start the engine. The engine is designed to
start in the P (Park) or N (Neutral) position only.
Always come to a complete stop before shifting into P (Park). Make sure
the gearshift is securely latched in P (Park). This position locks the
transmission and prevents the rear wheels from turning.
Always set the parking brake fully and make sure the gearshift
lever is latched in P (Park). Turn off the ignition whenever you
leave your vehicle.
When parking on hilly or off-road terrains, be sure to set the parking
brake fully and chock the wheels to prevent unexpected and possibly
sudden vehicle movement.
R (Reverse)
Use this position to move the vehicle backwards. Completely stop the
vehicle before shifting from a forward gear (1, 2, 4 or D) to R (Reverse),
or from R (Reverse) to any forward gear. The reverse warning signal will
sound when the selector is in R (Reverse). Reverse has only one gear
and provides the greatest gear reduction.
N (Neutral)
This position can be used when starting the engine. The engine is
designed to start in the P (Park) or N (Neutral) position only. The
