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).
Engine Hour Meter Display
The Driver Information Center (DIC) 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. SeeDIC Operation and Displays on page 266
for more information.
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, located on the instrument
panel cluster next to the trip odometer display,
to toggle between the trip odometer and the
regular odometer. Holding the reset button for
approximately one second while the trip odometer
is displayed will reset it.
To display the odometer reading with the ignition
off, press the reset button.
SeeDIC Operation and Displays on page 266for
more information.
Tachometer
Your tachometer displays the engine speed in
revolutions per minute (rpm). See “Grade Braking
(Allison Transmission
®)” underTow/Haul Mode
on page 147for more information.
Notice:If you operate the engine with the
tachometer in the solid red area, your vehicle
could be damaged. The damages would
not be covered by your warranty. Do not
operate the engine in the solid red area.
246

Here are some situations you may experience with
your fuel gage. None of these indicate a problem
with the fuel gage.
At the gas station, the fuel pump shuts off
before the gage reads full.
It takes a little more or less fuel to ll up than
the fuel gage indicated. For example, the
gage may have indicated the tank was half full,
but it actually took a little more or less than
half the tank’s capacity to ll the tank.
The gage goes back to empty when you turn
off the ignition.
If you have a diesel engine, see “Fuel Gage” in
the Diesel Engine Supplement.
Low Fuel Warning Light
The light next to the fuel gage will come on briey
when you are starting the engine.
This light comes on when the fuel tank is low on
fuel. To turn it off, add fuel to the fuel tank.
SeeFuel on page 470.
Driver Information Center (DIC)
The Driver Information Center (DIC) display is
located on the instrument panel cluster, below the
speedometer. If your vehicle has DIC buttons,
they are located on the steering wheel. The DIC
can display information such as the trip odometer,
fuel economy, customization features, and
warning/status messages.
If your vehicle does not have DIC steering wheel
buttons, you will not have all of the features
listed. Scroll through the odometer, trip odometer,
engine hours, and selected range if your vehicle
has an Allison Transmission
®by pressing the
trip odometer reset stem located on the instrument
panel cluster. Turn off, or acknowledge, DIC
messages by pressing the trip odometer reset
stem. SeeSpeedometer and Odometer on
page 246for information on features for vehicles
without DIC buttons.
265

If your vehicle has an Allison Transmission®and
the shift lever is in the MANUAL MODE (M)
position, the DIC will display the current gear
range. The DIC will also display the gear range as
it is shifted up or down. For example, if the gear
range is currently set to 6, the DIC will display
(6)54321. When thegear range is shifted down
one time, the DIC will display 6 (5)4321. See
Automatic Transmission Operation on page 140for

DIC Warnings and Messages
Warning messages are displayed on the Driver
Information Center (DIC) to notify the driver
that the status of the vehicle has changed and
that some action may be needed by the driver to
correct the condition. If there is more than one
message that needs to be displayed, they
will appear one after another. Some messages
may not require immediate action, but you should
press any of the four DIC buttons on the
steering wheel to acknowledge that you received
the messages and to clear them from the
display. If your vehicle does not have DIC buttons
on the steering wheel, press the trip odometer
reset stem, located on the instrument panel
cluster, to acknowledge messages and clear them
from the display.Some messages cannot be cleared from the
display because they are more urgent. These
messages require action before they can be
removed from the DIC display. You should take
any messages that appear on the display seriously
and remember that clearing the messages will
only make the messages disappear, not correct
the problem.
The following are the possible messages that can
be displayed and some information about them.
BATTERY NOT CHARGING
On some vehicles, if the battery is not charging
during operation, this message will appear on the
DIC. Driving with this problem could drain the
battery. Have the electrical system checked
by your dealer as soon as possible. Pressing any
of the four DIC buttons will acknowledge the
message and clear it from the DIC display. If your
vehicle does not have the four DIC buttons,
pressing the trip odometer reset stem will
acknowledge the message and clear it from the
DIC display. SeeBattery Warning Light on
page 253andVoltmeter Gage on page 253.
