Tire Pressure Monitor
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The TPMS warning light alerts you
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. SeeVehicle Load
Limits on page 9‑12. The warning
light will remain on until the tire
pressure is corrected.
During cooler conditions, the low tire
pressure warning light may appear
when the vehicle is first started and
then turn off. This may be an early indicator that the tire pressures are
getting low and the tires need to be
inflated to the proper pressure.
The TPMS does not replace normal
monthly tire maintenance. It is the
driver
’s responsibility to maintain
correct tire pressures.
See Tire Pressure Monitor System
on page 10‑47.Tire Sealant and
Compressor Kit
This vehicle may come with a jack
and spare tire or a tire sealant and
compressor kit. The kit can be used
to temporarily seal small punctures
in the tread area of the tire.
See Tire Sealant and Compressor
Kit on page 10‑63 for complete
operating information.
If the vehicle came with a jack and
spare tire, see If a Tire Goes Flat on
page 10‑61.
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.

OIL LIFE
Press the vehicle information
button until OIL LIFE REMAINING
displays. This display shows an
estimate of the oil's remaining
useful life. If you see 99% OIL LIFE
REMAINING on the display, that
means 99% of the current oil life
remains. The engine oil life system will alert you to change the oil on
a schedule consistent with your
driving conditions.
When the remaining oil life is low,
the CHANGE ENGINE OIL SOON
message will appear on the display.
See
“CHANGE ENGINE OIL SOON”
under Engine Oil Messages on
page 5‑40. You should change the
oil as soon as you can. See Engine
Oil on page 10‑8. In addition to the
engine oil life system monitoring the
oil life, additional maintenance is
recommended in the Maintenance
Schedule in this manual. See
Scheduled Maintenance on
page 11‑2 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,
see Engine Oil Life System on
page 10‑11. PARK ASSIST
If your vehicle has the Ultrasonic
Rear Parking Assist (URPA) system,
press the vehicle information button
until PARK ASSIST displays.
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. The URPA
system automatically turns back on
after each vehicle start. When the
URPA system is turned off and the
vehicle is shifted out of P (Park), the
DIC will display the PARK ASSIST
OFF message as a reminder that
the system has been turned off.

To use the retroactive reset feature,
press and hold the trip odometer
reset stem for at least four seconds.
The trip odometer will display
the number of kilometers (km)
or miles (mi) driven since the
ignition was last turned on and
the vehicle was moving. Once the
vehicle begins moving, the trip
odometer will accumulate mileage.
For example, if the vehicle was
driven 8 km (5 miles) before it
is started again, and then the
retroactive reset feature is activated,
the display will show 8 km (5 miles).
As the vehicle begins moving, the
display will then increase to 8.2 km
(5.1 miles), 8.4 km (5.2 miles), etc.
If the retroactive reset feature is
activated after the vehicle is started,
but before it begins moving, the
display will show the number of
kilometers (km) or miles (mi) that
were driven during the last ignition
cycle.OIL LIFE

10-52 Vehicle Care
Tire Rotation
Tires should be rotated every
12 000 km (7,500 miles).
SeeScheduled Maintenance on
page 11‑2.
The purpose of a regular tire
rotation is to achieve a uniform
wear for all tires on the vehicle.
This will ensure that the vehicle
continues to perform most like
it did when the tires were new.
The first rotation is the most
important. See Scheduled
Maintenance on page 11‑2.
Any time you notice unusual
wear, rotate the tires as soon
as possible and check wheel
alignment. Also check for
damaged tires or wheels.
See When It Is Time for New
Tires on page 10‑53 andWheel
Replacement on page 10‑59.
When rotating the vehicle's tires,
always use the correct rotation
pattern shown here.
If the vehicle has a compact
spare tire, do not include it in
the tire rotation.
After the tires have been
rotated, adjust the front and rear
inflation pressures as shown on
the Tire and Loading Information
label. See Tire Pressure on
page 10‑45 andVehicle Load
Limits on page 9‑12. Reset the Tire Pressure Monitor
System. See
Tire Pressure
Monitor Operation on
page 10‑48.
Make certain that all wheel
nuts are properly tightened.
See “Wheel Nut Torque” under
Capacities and Specifications on
page 12‑2.
{WARNING
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose
after time. The wheel could come
off and cause an accident. When
changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle.
In an emergency, use a cloth or
a paper towel to do this; but be
sure to use a scraper or wire
brush later, if needed, to get all
the rust or dirt off. See If a Tire
Goes Flat on page 10‑61.

11-2 Service and Maintenance
{WARNING
Performing maintenance work
can be dangerous. Some jobs
can cause serious injury. Perform
maintenance work only if you
have the required know-how and
the proper tools and equipment.
If in doubt, see your dealer to
have a qualified technician do
the work. SeeDoing Your Own
Service Work on page 10‑4.
At your dealer, you can be
certain that you will receive the
highest level of service available.
Your dealer has specially trained
service technicians, uses genuine
replacement parts, as well as,
up‐to‐date tools and equipment
to ensure fast and accurate
diagnostics. The proper replacement parts,
fluids, and lubricants to use are
listed in
Recommended Fluids
and Lubricants on page 11‑7 and
Maintenance Replacement Parts on
page 11‑9. We recommend the use
of genuine parts from your dealer.
Rotation of New Tires
To maintain ride, handling, and
performance of the vehicle, it is
important that the first rotation
service for new tires be performed.
Tires should be rotated every
12 000 km/7,500 miles. See Tire
Rotation on page 10‑52.
Scheduled
Maintenance
When the Change Engine Oil
Soon Message Displays

An Emission Control Service.
When the CHANGE ENGINE
OIL SOON message displays,
service is required for the vehicle
as soon as possible, within the next
1 000 km/600 miles. If driving under
the best conditions, the engine oil
life system might not indicate the
need for vehicle service for more
than a year. The engine oil and filter
must be changed at least once a
year and the oil life system must
be reset. Your dealer has trained
service technicians who will perform
this work and reset the system.
