the SELECT button until a check-mark appears next to
the setting, showing that the setting has been selected.
Compass / Temperature Display
The compass readings indicate the direction the vehicle is
facing. The EVIC will display one of eight compass
readings and the outside temperature.
NOTE:
•The system will display the last known outside tem-
perature when starting the vehicle and may need to be
driven several minutes before the updated tempera-
ture is displayed. Engine temperature can also affect
the displayed temperature; therefore, temperature
readings are not updated when the vehicle is not
moving.
•During snowplow usage on vehicles equipped with
outside temperature display, the display may show
higher temperatures than the outside ambient tem-
perature. The higher displayed temperature is due to
blocked or reduced airflow to the underhood ambient

WARNING! (Continued)
•Never use a tire with a smaller load index or
capacity, other than what was originally equipped
on your vehicle. Using a tire with a smaller load
index could result in tire overloading and failure.
You could lose control and have a collision result-
ing in serious injury or death.
•Failure to equip your vehicle with tires having
adequate speed capability can result in sudden tire
failure and loss of vehicle control resulting in
serious injury or death.
CAUTION!
Replacing original tires with tires of a different size
may result in false speedometer and odometer read-
ings.

seated; the gauges in the instrument cluster will do a
full sweep when the ignition switch is turned to the
RUN position. This is a normal condition.
•When the vehicle is shipped from the factory, the IOD
fuse is in the up or extracted position. If the radio,
interior lamps, keyless entry or other features do not
work with the key OFF, check the position of the fuse
(or check to see if the fuse is blown) to ensure that it is
fully seated. When the IOD fuse is extracted, the
instrument cluster in the odometer window will dis-
playNO FUSE.”

Page 460 of 508

MAINTENANCE SCHEDULE
5.7L Gas Engine
The Scheduled Maintenance services listed in this
manual must be done at the times or mileages specified
to protect your vehicle warranty and ensure the best
vehicle performance and reliability. More frequent main-
tenance may be needed for vehicles in severe operating
conditions, such as dusty areas and very short trip
driving. Inspection and service should also be done
anytime a malfunction is suspected.
The oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance.On Electronic Vehicle Information Center (EVIC)
equipped vehicles, “Oil Change Due” will be displayed
in the EVIC and a single chime will sound, indicating that
an oil change is necessary.
On Non-EVIC equipped vehicles, “Change Oil” will flash
in the instrument cluster odometer and a single chime
will sound, indicating that an oil change is necessary.
Based on engine operation conditions the oil change
indicator message will illuminate, this means that service
is required for your vehicle. Have your vehicle serviced
as soon as possible, within the next 500 miles (805 km).

NOTE:
•The oil change indicator message will not monitor the
time since the last oil change. Change your vehicles oil
if it has been 6 months since your last oil change even
if the oil change indicator message is NOT illumi-
nated.
•Change your engine oil more often if you drive your
vehicle off-road for an extended period of time.
•Under no circumstances should oil change intervals
exceed 8,000 miles (13 000 km) or 6 months, whichever
comes first.
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 byreferring to the steps described under “Electronic Vehicle
Information Center (EVIC)/Oil Change Due” in “Under-
standing Your Instrument Panel” or under “Instrument
Cluster Description/Odometer/Trip Odometer” in “Un-
derstanding Your Instrument Panel” for further informa-
tion.
At Each Stop For Fuel
•Check the engine oil level about 5 minutes after a fully
warmed engine is shut off. Checking the oil level while
the vehicle is on level ground will improve the accu-
racy of the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
•Check the windshield washer solvent and add if
required.
