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
of this message type are “Turn Signal On” (if a turn signal
is left on) and “Lights On” (if driver leaves the vehicle). •
Unstored Messages Until RUN
These messages deal primarily with the Remote Start
feature. This message type is displayed until the ignition is
in the RUN state. Examples of this message type are
“Remote Start Aborted - Door Ajar” and “Press Brake
Pedal and Push Button to Start.”
• Five Second Unstored 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. An example of this
message type is “Automatic High Beams On.”
Oil Life Reset
Your vehicle is equipped with an engine oil change indi-
cator system. The “Oil Change Required” message will
display in the instrument cluster display 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.
NOTE: Use the steering wheel instrument cluster display
controls for the following procedure(s).

MAINTENANCE SCHEDULE
Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change
indicator message will illuminate. This means that service
is required for your vehicle. Operating conditions such as
frequent short-trips, trailer tow, extremely hot or cold
ambient temperatures, and E85 fuel usage will influence
when the “Oil Change Required” message is displayed.
Severe Operating Conditions can cause the change oil
message to illuminate as early as 3,500 miles (5,600 km)
since last reset. Have your vehicle serviced as soon as
possible, within the next 500 miles (805 km).
Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a
scheduled oil change is performed by someone other than
your authorized dealer, the message can be reset by
referring to the steps described under “Instrument Cluster
Display” in “Understanding Your Instrument Panel” for
further information.Gasoline Engines:
Under no circumstances should oil change intervals exceed
8,000 miles (13,000 km), twelve months or 350 hours of
engine run time, whichever comes first. The 350 hours of
engine run or idle time is generally only a concern for fleet
customers.
Severe Duty:
Change Engine Oil at 4,000 miles (6,500 km) if the vehicle
is operated in a dusty and off road environment or is
operated predominately at idle or very low engine RPM’s.
This type of vehicle use is considered Severe Duty.
Once A Month Or Before A Long Trip:
•
Check engine oil level
• Check windshield washer fluid level
• Check the tire inflation pressures and look for unusual
wear or damage
• Check the fluid levels of the coolant reservoir, brake
master cylinder, power steering and automatic transmis-
sion, and fill as needed
• Check function of all interior and exterior lights
