Automatic Transmission Operation
If your vehicle is equipped with an automatic
transmission, it features an electronic shift position
indicator within the instrument panel cluster. This
display must be powered anytime the shift lever is
capable of being moved out of PARK (P). This means
that if your key is in OFF, rather than LOCK, there will
be a small current drain on your battery which could
discharge your battery over a period of time. If you have
to leave your key in the ignition in OFF for an extended
period, it is recommended that you remove the
IGN 0 fuse from the instrument panel fuse block.
See ªFuses and Circuit Breakersº in the Index.
There are several different positions for your shift lever.PARK (P): This position locks your rear wheels. It's the
best position to use when you start your engine because
your vehicle can't move easily. If your vehicle is equipped
with the Allison

Transmission, use park for stationary
operation of the Power Takeoff (PTO) (if equipped).
CAUTION:
It is dangerous to get out of your vehicle if the
shift lever is not fully in PARK (P) with the
parking brake firmly set. Your vehicle can roll.
Don't leave your vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure your
vehicle won't move, even when you're on fairly
level ground, always set your parking brake and
move the shift lever to PARK (P).
CAUTION: (Continued)

2-36
You can shift from 2-Wheel High (2HI) to
4
-Wheel High (4HI) or from 4-Wheel High (4HI) to
2
-Wheel High (2HI) while the vehicle is moving. Your
front axle will engage faster if you take your foot off of
the accelerator for a couple of seconds after you shift.
In extremely cold weather, it may be necessary to stop
or slow the vehicle to shift into 4
-Wheel High (4HI).
To shift into or out of 4
-Wheel Low (4LO)
or NEUTRAL (N):
1. Slow the vehicle to a roll, about 1 to 3 mph
(2 to 5 km/h) and shift an automatic transmission
into NEUTRAL (N), or with a manual transmission,
press the clutch pedal.
2. Shift the transfer case shift lever in
one continuous motion.
Don't pause in NEUTRAL (N) as you shift the transfer
case into 4
-Wheel Low (4LO), or your gears could clash.
Remember that driving in 4
-Wheel High (4HI) or
4
-Wheel Low (4LO) may reduce fuel economy. Also,
driving in four
-wheel drive on dry pavement could
cause your tires to wear faster and make your transfer
case harder to shift and run noisier.
Automatic Transfer Case (If Equipped)
The transfer case switches
are located to the left of the
instrument panel cluster.
Use these switches to shift into and out of four
-wheel drive.

2-40
Electronic Transfer Case (If Equipped)
If your four-wheel-drive vehicle has the electronic
transfer case, the transfer case switches are located to
the left of the instrument panel cluster.
Use these switches to shift into and out of four
-wheel
drive. You can choose among three driving settings:
2HI: This setting is for driving in most street and
highway situations. Your front axle is not engaged in
two
-wheel drive.
4HI: This setting engages your front axle to help drive
your vehicle. Use 4HI when you need extra traction, such
as on snowy or icy roads, or in most off
-road situations.
4LO: This setting also engages your front axle to give
you extra traction. You may never need 4LO. It sends
the maximum power to all four wheels. You might
choose 4LO if you were driving off
-road in sand, mud
or deep snow and climbing or descending steep hills.
Indicator lights in the switches show you which setting
you are in. The indicator lights will come on briefly
when you turn on the ignition and the last chosen setting
will stay on. If the lights do not come on, you should
take your vehicle in for service. An indicator light will
flash while shifting. It will remain illuminated when the
shift is completed. If for some reason the transfer
cannot make a requested shift, it will return to the last
chosen setting.

cargo lamp on. Press the
button again to turn it off.

turned on and the ignition
key is turned to RUN.
Battery Run-Down Protection
This feature shuts off the dome, reading, glove box,
cargo and underhood lamps if they are left on for more
than 20 minutes when the ignition is off. This will keep
your battery from running down.
Mirrors
Inside Day/Night Rearview Mirror

Instrument Panel Cluster
United States Heavy Duty Automatic Transmission version shown.
Canada, Light Duty Automatic and Manual Transmission clusters similar.

2-83
Your instrument cluster is designed to let you know at a
glance how your vehicle is running. You'll know how
fast you're going, about how much fuel you have and
many other things you'll need to know to drive safely
and economically.
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.
Press the reset button to toggle between the trip
odometer and the regular odometer. Holding the reset
button for two seconds while the trip odometer is
displayed will reset it.
To display the odometer reading with the ignition off,
press the reset button.Engine Hour Meter Display
The odometer can also display the number of hours the
engine has run. To display the hour meter, turn the
ignition off, press and hold the reset button for at least
four seconds. The hour meter will be displayed for up to
30 seconds, or until the ignition is turned on.Tachometer
Your tachometer displays the engine speed in
revolutions per minute (rpm).
NOTICE:
On vehicles with a manual transmission, if you
operate the engine with the tachometer in the
red area, your engine or other parts could
be damaged.
Damage to your engine or vehicle caused by
operating the engine in the red area isn't covered
by your vehicle warranty. Don't operate the
engine with the tachometer in the red area.

Message Center
The message center is located on the left side of the
instrument panel cluster. It gives you important safety
and maintenance facts. When you turn the ignition on,
the entire center lights up for just a few seconds.
As needed, the message center will display one of the
following messages. The message center is capable of
alternating among different messages if needed.
Battery
If this message is displayed
when the engine is running,
you may have a problem
with your charging system.
The battery display will also stay on while the key is in
RUN until the engine is started.If the message stays on after starting the engine it could
indicate a problem with the generator drive belt, or some
other charging system problem. Have it checked right
away. Driving with this message displayed could drain
your battery.
If you must drive a short distance with this message
displayed, it helps to turn off all your accessories, such
as the radio and the air conditioner.
Trans Fluid Hot
If you have an automatic transmission, you have a
transmission temperature warning display contained in
the message center.
If the transmission fluid
temperature becomes high,
the message center will
display this message.
