26. 4WD Indicator — Vehicles Equipped with
Selec-TracII
This light alerts the driver that the vehicle is in
the full-time four-wheel drive auto mode. In
this mode, the system operates with a normal
torque split of 42% front axle and 58% rear axle.
It can redirect up to 100% of torque to the front or rear
axle, if necessary.
27. Odometer/Trip Odometer
The odometer shows the total distance the vehicle has
been driven. The trip odometer shows individual trip
mileage. Refer to “Trip Odometer button” for additional
information.
NOTE: U.S. Federal regulations require upon transfer of
vehicle ownership, the seller certify the mileage the
vehicle has been driven. Therefore, if the odometer
reading is changed because of repair or replacement, be sure to keep a record of the reading before and after the
service so that the correct mileage can be determined.
Vehicle Warning Messages
When the appropriate conditions exist, messages such as
“door” (door ajar), “gATE” (liftgate ajar), “gLASS”
(flip-up glass ajar), “gASCAP” (fuel cap fault), “LoW
tirE” (low tire pressure), or “CHANgE OIL” will display
in the odometer.
LoW tirE
When the appropriate condition exists, the odometer
display will toggle between LoW and tirE for three
cycles.
NOTE:
If the instrument cluster is equipped with the
optional Electronic Vehicle Information Center (EVIC),
then most warnings will display in the EVIC.

Fuel Cap Fault Message
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, the
words “gASCAP” will display in the odometer. If this
occurs, tighten the fuel filler cap properly and press the
odometer reset button to turn off the message. If the
problem continues, the message will appear the next time
the vehicle is started.
A loose, improperly installed, or damaged fuel filler cap
may also turn on the Malfunction Indicator Light (MIL).
Change Oil Message (Base And Mid Line Clusters
Only)
Your vehicle is equipped with an engine oil change
indicator system. The “CHANgE OIL” message will flash
in the instrument cluster odometer for approximately
12 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, whichmeans the engine oil change interval may fluctuate
dependent upon your personal driving style.
Unless reset, this message will continue to display each
time you turn the ignition switch to the ON position. To
turn off the message temporarily, press and release the
Trip Odometer button on the instrument cluster. To reset
the oil change indicator system (after performing the
scheduled maintenance) perform the following proce-
dure:
1. Turn the ignition switch to the ON position. Do not
start the engine.
2. Fully depress the accelerator pedal slowly three
times within 10 seconds.
3. Turn the ignition switch to the LOCK position.
NOTE: If the indicator message illuminates when you
start the vehicle, the oil change indicator system did not
reset. If necessary, repeat this procedure.

Oil Change Required
Your vehicle is equipped with an engine oil change
indicator system. The “Oil Change Required” message
will flash in the EVIC display for approximately 10 sec-
onds 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

tion:
•Average Fuel Economy
Shows the average fuel economy since the last reset. When
the fuel economy is reset, the display will read “RESET” or
show dashes for two seconds. Then, the history informa-
tion will be erased, and the averaging will continue from
the last fuel average reading before the reset.

These indicators are molded into the bottom of the tread
grooves. They will appear as bands when the tread depth
becomes 1/16 in (2 mm). When the indicators appear in
two or more adjacent grooves, the tire should be replaced.
Life Of Tire
The service life of a tire is dependent upon various
factors including but not limited to:
•Driving style
•Tire pressure
•Distance driven
WARNING!
Tires and the spare tire should be replaced after six
years, regardless of the remaining tread. Failure to
follow this warning can result in sudden tire failure.
You could lose control and have an accident resulting
in serious injury or death.Keep dismounted tires in a cool, dry place with as little
exposure to light as possible. Protect tires from contact
with oil, grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for
wear and correct cold tire inflation pressure. The manu-
facturer strongly recommends that you use tires equiva-
lent to the originals in size, quality and performance
when replacement is needed. (Refer to the paragraph on
“Tread Wear Indicators”). Refer to the “Tire and Loading
Information” placard for the size designation of your
tires. The service description and load identification will
be found on the original equipment tire. Failure to use
equivalent replacement tires may adversely affect the
safety, handling, and ride of your vehicle. We recommend
that you contact your original equipment or an autho-
rized tire dealer with any questions you may have on tire
specifications or capability.
352 STARTING AND OPERATING

Problems that result from using methanol/gasoline or
E85 Ethanol blends are not the responsibility of the
manufacturer. While MTBE is an oxygenate made from
Methanol, it does not have the negative effects of
Methanol.
E-85 Usage In Non-Flex Fuel Vehicles
Non-FFV vehicles are compatible with gasoline contain-
ing 10% ethanol (E10). Gasoline with higher ethanol
content may void the vehicle’s warranty.
If a Non-FFV vehicle is inadvertently fueled with E-85
fuel, the engine will have some or all of these symptoms:
•operate in a lean mode
•OBD II “Malfunction Indicator Light” on
•poor engine performance
•poor cold start and cold drivability
•increased risk for fuel system component corrosionTo fix a Non-FFV vehicle inadvertently fueled once with
E-85 perform the following:
•drain the fuel tank (see your authorized dealer)
•change the engine oil and oil filter
•disconnect and reconnect the battery to reset the
engine controller memory
More extensive repairs will be required for prolonged
exposure to E-85 fuel.
MMT In Gasoline
MMT is a manganese containing metallic additive that is
blended into some gasoline to increase octane. Gasoline
blended with MMT provides no performance advantage
beyond gasoline of the same octane number without
MMT. Gasoline blended with MMT reduces spark plug
life and reduces emission system performance in some
vehicles. The manufacturer recommends that gasoline
without MMT be used in your vehicle. The MMT content
