low, the vehicle will start and then shut down in
10 seconds.
The park lamps will turn on and remain on
during Remote Start mode.
For security, power window operation is
disabled when the vehicle is in the Remote Start
mode.
The ignition must be placed in the ON/RUN posi -
tion before the Remote Start sequence can be
repeated for a third cycle. All of the following conditions must be met before
the engine will remote start:
Gear selector in PARK
Doors closed
Hood closed
Liftgate closed
Hazard switch off
Brake switch inactive (brake pedal not pressed)
Battery at an acceptable charge level
PANIC button not pushed
System not disabled from previous remote start

INSTRUMENT CLUSTER DESCRIPTIONS

1. Tachometer

Indicates the engine speed in revolutions
per minute (RPM x 1000).
2. Speedometer
Indicates vehicle speed.
3. 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. 4. Instrument Cluster DisplayThe instrument cluster display features a
driver interactive display Ú
page 83.
5. 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 Ú page 140.
NOTE:The hard telltales will illuminate for a bulb check
when the ignition is first cycled.
INSTRUMENT CLUSTER DISPLAY
Your vehicle is 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
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.
LOCATION AND CONTROLS
The instrument cluster display is located in the
center of the instrument cluster.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
Úpage 280.
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.
