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 engine hours, 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 (With
DIC Buttons) on page 268orDIC Operation and
Displays (Without DIC Buttons) on page 275
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 voltmeter, 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 (With DIC
Buttons) on page 268orDIC Operation and
Displays (Without DIC Buttons) on page 275for
more information.
Tachometer
Your tachometer displays the engine speed in
revolutions per minute (rpm). See “Grade Braking
(Allison Transmission
®)” underTow/Haul Mode
on page 144for more information.

Voltmeter Gage
Your vehicle may have
a voltmeter gage.
When the ignition is in RUN, this gage indicates
the battery voltage.
When the engine is running, this gage shows the
condition of the charging system. The gage
may transition from a higher to lower or a lower to
higher reading, this is normal. If the vehicle is
operating outside the normal operating range, thecharging system light will come on. SeeCharging
System Light on page 254for more information.
The voltmeter gage may also read lower when in
fuel economy mode. This is normal.
Readings outside the normal operating range may
also occur when a large number of electrical
accessories are operating in the vehicle and the
engine is left idling for an extended period.
This condition is normal since the charging system
is not able to provide full power at engine idle.
As engine speeds are increased, this condition
should correct itself as higher engine speeds allow
the charging system to create maximum power.
You can only drive for a short time with the readings
outside the normal operating range. If you must
drive, turn off all unnecessary accessories.
Readings outside the normal operating range
indicate a possible problem in the electrical system.
Have the vehicle serviced as soon as possible.
