LUSTER DESCRIPTIONS

1. Speedometer

Indicates vehicle speed.
2. Temperature Gauge
The temperature gauge shows engine
coolant temperature. Any reading within the
normal range indicates that the engine
cooling system is operating satisfactorily.
The pointer will likely indicate a higher
temperature 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. 3. Tachometer
Indicates the engine speed in revolutions
per minute (RPM x 1000).
4. Fuel Gauge
The pointer shows the level of fuel in the
fuel tank when the Keyless Push Button
Ignition is in the ON/RUN position.
 The fuel pump symbol points to
the side of the vehicle where the
fuel door is located.
NOTE:The Instrument Cluster Warning Indicators will illu -
minate briefly for a bulb check when the ignition is
first cycled.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. It is recommended to call an authorized
dealer for service if your vehicle overheats
Ú page 346.
CAUTION!
Driving with a hot engine cooling system could
damage 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
Depending on your vehicles trim level, features
and options may vary.
Your vehicle will be equipped with an instrument
cluster display, which offers useful information to
the driver. With the ignition in the 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
information 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 systems 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
selections and adjustments.

Oil Change Required

Your vehicle is equipped with an
engine oil change indicator system.
The “Oil Change Required”
message will display in the
instrument cluster display for five seconds after a
single chime has sounded, to indicate the next
scheduled oil change interval. The engine oil change
indicator system is duty cycle based, which means
the engine oil change interval may fluctuate,
dependent upon your personal driving style.

Unless reset, this message will continue to display
each time the ignition is placed in the ON/RUN
position. To turn off the message temporarily, push
and release the OK or arrow buttons. To reset the
oil change indicator system (after performing the
scheduled maintenance), refer to the following
procedure.

DISPLAY AND MESSAGES
The instrument cluster display is located in the
center portion of the cluster and consist of multiple
sections:
Main Screen — The inner ring of the display will
illuminate in black under normal conditions,
yellow for non critical warnings and red for crit -
ical warnings
Submenu Dots — Whenever there are
submenus available, the position within the
submenus is shown here
Reconfigurable Telltales/Information
Gear Selector Status (PRND)
Driver Interactive Display (Compass, Temp,
Range to Empty, Trip A, Trip B, Average Fuel
Economy, Current Fuel Economy and Time)
Air Suspension Status — If Equipped
Four-Wheel Drive (4WD) Status — If Equipped
The instrument cluster display 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 and warning or
information messages. These pop-up messages
fall into several categories:
Five Second Stored Messages
When the appropriate conditions occur, this
type of message 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 condi-
tion that activated it remains active) and can be
reviewed from the “Messages” main menu item.
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 of this message type are
“Turn Signal On” (if a turn signal is left on) and
“Lights On” (if driver leaves the vehicle with the
lights on).
