the following menu items:
Odometer
Press the trip/fuel button until ODOMETER displays.

been driven in either miles (mi) or kilometers (km).
Pressing the trip odometer reset stem will also
display the odometer.
To switch between English and metric measurements,
see “Units” later in this section.

When the remaining oil life is low, the CHANGE
ENGINE OIL SOON message will appear on the display.
See “CHANGE ENGINE OIL SOON” underDIC
Warnings and Messages on page 3-56. You should
change the oil as soon as you can. SeeEngine Oil
on page 5-13. 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
for more information.
Remember, you must reset the OIL LIFE display
yourself after each oil change. It will not reset itself.
Also, be careful not to reset the OIL LIFE display
accidentally at any time other than when the oil has
just been changed. It cannot be reset accurately until
the next oil change. To reset the engine oil life system,
seeEngine Oil Life System on page 5-16.
Units
Press the vehicle information button until UNITS
displays. This display allows you to select between
English or Metric units of measurement. Once in this
display, press the set/reset button to select between
ENGLISH or METRIC units. All of the vehicle information
will then be displayed in the unit of measurement
selected.
Tire Pressure
The pressure for each tire can be viewed in the DIC.
The tire pressure will be shown in either pounds
per square inch (psi) or kilopascals (kPa). Press
the vehicle information button until the DIC displays
FRONT TIRES PSI (kPa) LEFT ## RIGHT ##. Press
the vehicle information button again until the DIC
displays REAR TIRES PSI (kPa) LEFT ## RIGHT ##.
If a low or high tire pressure condition is detected by
the system while driving, a message advising you
to check the pressure in a specic tire will appear in
the display. SeeInflation - Tire Pressure on page 5-61
andDIC Warnings and Messages on page 3-56for
more information.
If the tire pressure display shows dashes instead of
a value, there may be a problem with your vehicle.
If this consistently occurs, see your dealer/retailer
for service.
Engine Hours
Press the vehicle information button until
ENGINE HOURS displays. This display shows
the total number of hours the engine has run.

DIC Warnings and Messages
Messages are displayed on the DIC to notify the
driver that the status of the vehicle has changed and
that some action may be needed by the driver to
correct the condition. Multiple messages may appear
one after another.
Some messages may not require immediate action,
but you can press any of the DIC buttons on the
instrument panel or the trip odometer reset stem on
the instrument panel cluster to acknowledge that
you received the messages and to clear them from
the display.
Some messages cannot be cleared from the DIC
display because they are more urgent. These messages
require action before they can be cleared. You should
take any messages that appear on the display seriously
and remember that clearing the messages will only
make the messages disappear, not correct the problem.
The following are the possible messages that can
be displayed and some information about them.
CHANGE ENGINE OIL SOON
This message displays when the engine oil needs to
be changed. When you change the engine oil, be sure
to reset the CHANGE ENGINE OIL SOON message.
SeeEngine Oil Life System on page 5-16for information
on how to reset the message. SeeEngine Oil on
page 5-13andScheduled Maintenance on page 6-4
for more information.
CHECK TIRE PRESSURE
This message displays when the pressure in one
or more of the vehicle’s tires needs to be checked. This
message also displays LEFT FRONT, RIGHT FRONT,
LEFT REAR, or RIGHT REAR to indicate which tire
needs to be checked. You can receive more than one
tire pressure message at a time. To read the other
messages that may have been sent at the same time,
press the set/reset button or the trip odometer reset
stem. If a tire pressure message appears on the DIC,
stop as soon as you can. Have the tire pressures
checked and set to those shown on the Tire Loading
Information label. SeeTires on page 5-55,Loading Your
Vehicle on page 4-44, andInflation - Tire Pressure on
page 5-61. The DIC also shows the tire pressure values.
See “DIC Operation and Displays (Using DIC Buttons)”
earlier in this section. If the tire pressure is low,
the low tire pressure warning light comes on.
SeeTire Pressure Light on page 3-41.

First Aid Kit and Tool Kit
The rst aid and tool kit is located in the storage bin
behind the spare tire on SUV models. It is held in place
with a hook and loop fastener strap.
On SUT models, the kit is in the rear cargo compartment
on the passenger side of the vehicle.
The kit includes a rst aid kit, a ashlight, a tire pressure
gage, and a multi-purpose tool set.The tire pressure gage has a reset button in the gage
stem. After taking a pressure reading, press the
button to reset the gage to zero.
4-42

Tire Pressure Monitor Operation
The Tire Pressure Monitor System (TPMS) is designed
to warn the driver when a low tire pressure condition
exists. TPMS sensors are mounted onto each tire
and wheel assembly, excluding the spare tire and wheel
assembly. The TPMS sensors monitor the air pressure
in the vehicle’s tires and transmits the tire pressure
readings to a receiver located in the vehicle.
When a low tire pressure
condition is detected,
the TPMS illuminates
the low tire pressure
warning light located on
the instrument panel
cluster.
At the same time a message to check the pressure in a
specic tire appears on the Driver Information Center
(DIC) display. The low tire pressure warning light
and the DIC warning message come on at each ignition
cycle until the tires are inated to the correct ination
pressure. Using the DIC, tire pressure levels can be
viewed by the driver. For additional informationand details about the DIC operation and displays see
DIC Operation and Displays (Using DIC Buttons)
on page 3-49orDIC Operation and Displays (Using Trip
Odometer Reset Stem) on page 3-54andDIC
Warnings and Messages on page 3-56.
The low tire pressure warning light may come on in cool
weather when the vehicle is rst started, and then
turn off as you start to drive. This could be an early
indicator that the air pressure in the tire(s) are getting
low and need to be inated to the proper pressure.
A Tire and Loading Information label, attached to your
vehicle, shows the size of your vehicle’s original
equipment tires and the correct ination pressure for
your vehicle’s tires when they are cold. SeeLoading
Your Vehicle on page 4-44, for an example of the Tire
and Loading Information label and its location on
your vehicle. Also seeInflation - Tire Pressure on
page 5-61.
Your vehicle’s TPMS can warn you about a low tire
pressure condition but it does not replace normal
tire maintenance. SeeTire Inspection and Rotation on
page 5-67andTires on page 5-55.
Notice:Liquid tire sealants could damage the Tire
Pressure Monitor System (TPMS) sensors. Sensor
damage caused by using a tire sealant is not
covered by your warranty. Do not use liquid tire
sealants.

When rotating your vehicle’s tires, always use
one of the correct rotation pattern shown here.
The ve-tire rotation pattern includes a full-size
spare tire and wheel assembly that matches
the regular road tires and wheels in size, type,
and brand.
After the tires have been rotated, adjust the front
and rear ination pressures as shown on the Tire
and Loading Information label. SeeInflation - Tire
Pressure on page 5-61andLoading Your Vehicle
on page 4-44.
Reset the Tire Pressure Monitor System. SeeTire
Pressure Monitor Operation on page 5-64.
Make certain that all wheel nuts are properly
tightened. See “Wheel Nut Torque” under
Capacities and Specifications on page 5-117.
