SETTINGS (Display Current Settings)
This feature displays your vehicle personalization
settings.
OIL LIFE (Engine Oil Life System Reset)
This feature allows you to reset the engine oil life
system after an oil change. Be careful not to reset the
OIL LIFE at any time other than when the oil has
been changed. To clear the CHANGE ENGINE OIL light
from the instrument panel cluster and reset the engine
oil life system, do the following:
1. Scroll, using the SEEK/PSCAN up or down arrows,
until OIL LIFE appears on the display.
2. Press the PREV or NEXT button to enter the
submenu. RESET will then be displayed.
3. Press the TUNE/DISP knob to reset. A chime will
be heard to verify the new setting and DONE will
be displayed for one second.
Also see “How to Reset the Engine Oil Life System”
underEngine Oil Life System on page 5-21andEngine
Oil on page 5-18for more information.
In addition to the engine oil life system monitoring the
oil life, additional maintenance is recommended in
the Maintenance Schedule in this manual.
SeeScheduled Maintenance on page 6-4.The CHANGE ENGINE OIL light is now reset. You can
either exit the programming mode by following the
instructions later in this section or program the next
feature available on your vehicle.
TIRE MON (Tire Ination Monitor Reset)
This feature allows you to reset the tire pressure
monitor after checking all tire pressures. SeeTires on
page 5-60. To clear the LOW TIRE PRESSURE light
from the instrument panel cluster and reset the low tire
pressure monitor, do the following:
1. Scroll, using the SEEK/PSCAN up or down arrows,
until TIRE MON appears on the display.
2. Press the PREV or NEXT button to enter the
submenu. RESET will be displayed.
3. Press the TUNE/DISP knob to reset. A chime will
be heard to verify the new setting and DONE will
be displayed for one second.
The low tire pressure monitor is now reset. You can
either exit the programming mode by following the
instructions later in this section or program the next
feature available on your vehicle.

Change Engine Oil Message
When this message comes on, it means that service is
required for your vehicle. It will appear for 60 seconds.
SeeScheduled Maintenance on page 6-4and
Engine Oil on page 5-18for more information.
Once the engine oil has been changed, the CHANGE
ENGINE OIL message must be reset. Until it is
reset, this message will be displayed for 60 seconds
each time you start the engine. For more information on
resetting the system, see “How to Reset the Change
Engine Oil Message” underEngine Oil on page 5-18.
Low Tire Message
Your vehicle may be equipped with the tire pressure
system which monitors the ination pressure of the tires.
After the system has “learned” the tire pressure with
properly inated tires, the LOW TIRE PRESSURE
message will be displayed and four warning chimes will
sound if the tire pressure in one tire becomes 12 psi
(83 kPa) lower than the other three tires.
When you have checked the tire pressures, be sure to
reset the tire ination monitor. See “Tire Pressure
Monitor System” underTires on page 5-60. United States
CanadaUnited StatesCanada

Tire Pressure Monitor System
If your vehicle has the tire pressure monitor system,
it can alert you to a large change in the pressure of one
tire. The system “learns” the pressure at each tire
throughout the operating speed range of your vehicle.
The system normally takes between 45 and 90 minutes
of driving to learn the tire pressures. This time may
be longer depending on your individual driving habits.
Learning need not be accumulated during a single
trip. Once learned, the system will remember the tire
pressures until the system is recalibrated.
After the system has learned tire pressures with
properly inated tires, the LOW TIRE PRESSURE
message will come on if the pressure in one tire
becomes 12 psi (83 kPa) lower than the other
three tires. The tire pressure monitor system won’t
alert you if the pressure in more than one tire is low,
if the system is not properly calibrated, or if the vehicle
is moving faster than 70 mph (110 km/h).
The tire pressure monitor system detects differences
in tire rotation speeds that are caused by changes
in tire pressure. The system can alert you about a
low tire — but it doesn’t replace normal tire
maintenance. SeeTires on page 5-60.When the LOW TIRE PRESSURE message comes on,
you should stop as soon as you can and check all
your tires for damage. (If a tire is at, seeIf a Tire Goes
Flat on page 5-77.) Also check the tire pressure in all
four tires as soon as you can. SeeInation - Tire
Pressure on page 5-66.
The LOW TIRE PRESSURE message will also be
displayed (while the ignition is on) until you reset
(calibrate) the system.
Don’t reset the tire pressure monitor system without rst
correcting the cause of the problem and checking
and adjusting the pressure in all four tires. If you reset
the system when the tire pressures are incorrect,
the system will not work properly and may not alert you
when a tire is low.
Any time you adjust a tire’s pressure, rotate your tires,
or have one or more tires repaired or replaced, you’ll
need to reset (calibrate) the tire pressure monitor
system. You’ll also need to reset the system whenever
you buy new tires and whenever the vehicle’s battery
has been disconnected.

The tire pressure monitor system can be reset two ways.
To reset (calibrate) the system using the ignition, do the
following:
1. Turn the ignition position to ON.
2. Pull the exterior lamp control from the ON position
to the OFF position three times.
To reset (calibrate) the system through the radio,
do the following:
1. Turn the ignition to ACC or ON and turn the
radio off.
2. Press and hold the TUNE DISPL button on the
radio for at least ve seconds until SETTINGS is
displayed.
3. Press the SEEK PSCAN up or down arrow to scroll
through the main menu.
4. Scroll until TIRE MON appears on the display.
5. Press the 1 PREV or 2 NEXT button to enter the
submenu. RESET will be displayed.6. Press the TUNE DISPL button to reset. A chime will
be heard to verify the new setting and DONE will
be displayed for one second.
7. Once the monitor has been reset, scroll until EXIT
appears on the display.
8. Press the TUNE DISPL button to exit programming.
A chime will be heard to verify exit.
The system completes the calibration process during
driving.
The system normally takes 15 to 20 minutes of driving
in each of three speed ranges to “learn” tire pressures.
The speed ranges are 15 to 40 mph (25 to 65 km/h),
40 to 65 mph (65 to 105 km/h) and above 65 mph
(105 km/h). When learning is complete, the system will
alert you after two to eight minutes if a tire is 12 psi
(83 kPa) different from the other three tires. Detection
thresholds may be higher and detection times may
be longer on rough roads, curves and at high speeds.
The system is not capable of detection at speeds greater
than 70 mph (110 km/h).

Tire Inspection and Rotation
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km).
Any time you notice unusual wear, rotate your tires as
soon as possible and check wheel alignment. Also check
for damaged tires or wheels. SeeWhen It Is Time for
New Tires on page 5-71andWheel Replacement on
page 5-74for more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The rst rotation
is the most important. SeeScheduled Maintenance
on page 6-4for scheduled rotation intervals.When rotating your tires, always use the correct rotation
pattern shown here.
Don’t include the compact spare tire in your tire rotation.
After the tires have been rotated, adjust the front and
rear ination pressures as shown on the Tire and
Loading Information label.
Reset the Tire Ination Monitor System. SeeTire
Pressure Monitor System on page 5-68.
