1-22 In Brief
Tire Pressure Monitor
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The low tire pressure warning light
alerts to a significant loss in
pressure of one of the vehicle's
tires. If the warning light comes on,
stop as soon as possible and inflate
the tires to the recommended
pressure shown on the Tire and
Loading Information label. See
Vehicle Load Limits on page 9-9.
The warning light will remain on until
the tire pressure is corrected.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
may be an early indicator that thetire pressures are getting low and
the tires need to be inflated to the
proper pressure.
The TPMS does not replace normal
monthly tire maintenance. Maintain
the correct tire pressures.
See
Tire Pressure Monitor System
on page 10-46.
Engine Oil Life System
The engine oil life system calculates
engine oil life based on vehicle use
and displays the CHANGE ENGINE
OIL SOON message when it is time
to change the engine oil and filter.
The oil life system should be reset
to 100% only following an oil
change.
Resetting the Oil Life System
1. Turn the ignition to ON/RUN, with the engine off.
2. Press the vehicle information button until OIL LIFE
REMAINING displays. 3. Press and hold the set/reset
button until “100%”is displayed.
Three chimes sound and the
CHANGE ENGINE OIL SOON
message goes off.
4. Turn the key to LOCK/OFF.
See Engine Oil Life System on
page 10-9.

5-26 Instruments and Controls
REAR CROSS TRAFFIC ALERT
If the vehicle has the Rear Cross
Traffic Alert (RCTA) system, this
display allows the system to be
turned on or off. Once in this
display, press the set/reset button to
select between ON or OFF. If you
choose ON, the system will be
turned on. If you choose OFF, the
system will be turned off. When the
RCTA system is turned off, the DIC
will display the REAR CROSS
TRAFFIC ALERT SYSTEM OFF
message as a reminder that the
system has been turned off. See
Object Detection System Messages
on page 5-37andRear Vision
Camera (RVC) on page 9-38.
UNITS
Press the vehicle information button
until UNITS displays. This display
allows you to select between metric
or English units of measurement.
Once in this display, press the set/
reset button to select between
METRIC or ENGLISH units. All of the vehicle information will then be
displayed in the unit of
measurement selected.
FRONT TIRES or REAR TIRES
On vehicles with the Tire Pressure
Monitor System (TPMS), the
pressure for each tire can be viewed
in the DIC. The tire pressure will be
shown in either kilopascals (kPa) or
pounds per square inch (psi). Press
the vehicle information button until
the DIC displays FRONT
TIRES kPa (PSI) LEFT ##
RIGHT ##. Press the vehicle
information button again until the
DIC displays REAR TIRES kPa
(PSI) LEFT ## RIGHT ##.
If a low tire pressure condition is
detected by the system while
driving, a message advising you to
add air to a specific tire will appear
in the display. See
Tire Pressure on
page 10-45 andTire Messages on
page 5-40. 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 for service.

This display will be available if the
vehicle has a compass. See

Vehicle Care 10-51
.The tire has a bump, bulge,
or split.
.The tire has a puncture, cut,
or other damage that cannot
be repaired well because of
the size or location of the
damage.
Tire Rotation
Tires should be rotated every
12 000 km (7,500 mi). See
Maintenance Schedule on
page 11-2.
Tires are rotated to achieve a
uniform wear for all tires. The
first rotation is the most
important.Anytime unusual wear is
noticed, rotate the tires as soon
as possible, check for proper tire
inflation pressure, and check for
damaged tires or wheels. If the
unusual wear continues after the
rotation, check the wheel
alignment. See
When It Is Time
for New Tires on page 10-52
and Wheel Replacement on
page 10-57.
Use this rotation pattern when
rotating the tires. If the vehicle has a compact
spare tire, do not include it in the
tire rotation.
Adjust the front and rear tires to
the recommended inflation
pressure on the Tire and
Loading Information label after
the tires have been rotated. See
Tire Pressure on page 10-45
and
Vehicle Load Limits on
page 9-9.
Reset the Tire Pressure Monitor
System. See Tire Pressure
Monitor Operation on
page 10-47.
Check that all wheel nuts are
properly tightened. See “Wheel
Nut Torque” underCapacities
and Specifications on
page 12-2.
