Base Instrument Cluster Descriptions
1. Tachometer•Indicates the engine speed in revolutions per minute
(RPM x 1000).
2. Instrument Cluster Display •When the appropriate conditions exist, this display
shows the instrument cluster display messages. Refer
to “Instrument Cluster Display” in “Getting To Know
Your Instrument Panel” for further information.
3. Speedometer •Indicates vehicle speed.
4. Fuel Gauge •The pointer shows the level of fuel in the fuel tank
when the ignition is in the ON/RUN position.
•
The fuel pump symbol points to the side of the
vehicle where the fuel door is located.
5. Temperature Gauge
•The temperature gauge shows engine coolant tem-
perature. Any reading within the normal range indi-
cates that the engine cooling system is operating
satisfactorily. •
The gauge pointer will likely indicate a higher tem-
perature when driving in hot weather, up mountain
grades, or when towing a trailer. It should not be
allowed to exceed the upper limits of the normal
operating range.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer for
service if your vehicle overheats. If you decide to look
under the hood yourself, see “Servicing And Mainte-
nance.” Follow the warnings under the Cooling System
Pressure Cap paragraph.
CAUTION!
Driving with a hot engine cooling system could dam-
age your vehicle. If the temperature gauge reads “H,”
pull over and stop the vehicle. Idle the vehicle with the
air conditioner turned off until the pointer drops back
into the normal range. If the pointer remains on the
“H,” turn the engine off immediately and call an
authorized dealer for service.

INSTRUMENT CLUSTER DISPLAY
Your vehicle may be equipped with an instrument cluster
display, which offers useful information to the driver. With
the ignition in the STOP/OFF mode, opening/closing of a
door will activate the display for viewing, and display the
total miles, or kilometers, in the odometer. Your instrument
cluster display is designed to display important informa-
tion about your vehicle’s systems and features. Using a
driver interactive display located on the instrument panel,
your instrument cluster display can show you how sys-
tems are working and give you warnings when they are
not. The steering wheel mounted controls allow you to
scroll through the main menus and submenus. You can
access the specific information you want and make selec-
tions and adjustments.
172 GETTING TO KNOW YOUR INSTRUMENT PANEL

The instrument cluster display screens are located in the
center portion of the cluster and consists of eight sections:
1. Main Screen — The inner ring of the display willilluminate in grey under normal conditions, yellow for
non critical warnings, red for critical warnings, and
white for on demand information.
2. Audio / Phone Information and Submenu Information — Whenever there are submenus available, the position
within the submenus is shown here.
3. Selectable Information (Compass, Outside Temp, Range to Empty, Trip A, Trip B, Average Fuel Economy, Trailer
Trip (distance only), Trailer Brake Gain, Time)
4. Telltales/Indicators
5. Gear Selector Status
6. Selectable Menu Icons
7. Air Suspension Status – If Equipped
8. 4WD Status
9. Selectable Gauge 2 (Trans Temp, Oil Temp, Oil Life, Trailer Brake, Current Fuel Economy) 10. Selectable Gauge 1 (Trans Temp, Oil Temp, Oil Life,
Trailer Brake, Current fuel economy)
The instrument cluster display area will normally display
the main menu or the screens of a selected feature of the
main menu. The main display area also displays “pop up”
messages that consist of approximately 60 possible warn-
ing or information messages. These pop up messages fall
into several categories:
• Five Second Stored Messages
When the appropriate conditions occur, this type of mes-
sage takes control of the main display area for five seconds
and then returns to the previous screen. Most of the
messages of this type are then stored (as long as the
condition that activated it remains active) and can be
reviewed from the “Messages” main menu item. As long as
there is a stored message, an “i” will be displayed in the
instrument cluster display’s compass/outside temp line.
Examples of this message type are “Right Front Turn Signal
Lamp Out” and “Low Tire Pressure.”
• Unstored Messages
This message type is displayed indefinitely or until the
condition that activated the message is cleared. Examples
