the tires to the recommended
pressure shown on the Tire and
Loading Information label. See
Vehicle Load Limits0163. 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 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. Maintain
the correct tire pressures.

0 252.Fuel (2.0L Turbo Engine)
Premium Recommended Fuel
Use premium 93 octane unleaded
gasoline in your vehicle. Unleaded
gasoline with an octane rating as
low as 87 may be used, but it will
reduce performance and fuel
economy. See Fuel0205.
Fuel (2.4L Engine)
Regular Fuel
Use only unleaded gasoline rated
87 octane or higher in your vehicle.
Do not use gasoline with an octane rating lower as it may result in
vehicle damage and lower fuel
economy. See

No E85 or FlexFuel
Gasoline-ethanol fuel blends greater
than E15 (15% ethanol by volume),
such as E85, cannot be used in this

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.

gallon (mpg). This number reflects
only the approximate fuel economy
that the vehicle has right now and
changes frequently as driving
conditions change.
Average Speed : Displays the
average speed of the vehicle in
kilometers per hour (km/h) or miles
per hour (mph). This average is
calculated based on the various
vehicle speeds recorded since the

There are two minutes to match the
first tire/wheel position, and
five minutes overall to match all four
tire/wheel positions. If it takes
longer, the matching process stops
and must be restarted.
The TPMS sensor matching
process is:1. Set the parking brake.
2. Turn the ignition to ON/RUN with the engine off or place the
vehicle power mode in ON/
RUN/START.
See Ignition Positions (Key
Access) 0167 orIgnition
Positions (Keyless Access)
0 168.
3. Make sure the Tire Pressure info page option is turned on.
The info pages on the DIC can
be turned on and off through
the Settings menu.
See Driver Information Center
(DIC) (Base Level) 0119 or
Driver Information Center (DIC)
(Uplevel) 0122. 4. Use the DIC controls on the
right side of the steering wheel
to scroll to the Tire Pressure
screen under the DIC
info page.
5. Press and hold the
V(Set/
Reset) button located in the
center of the DIC controls.
The horn sounds twice to
signal the receiver is in relearn
mode and the TIRE
LEARNING ACTIVE message
displays on the DIC screen.
6. Start with the driver side front tire.
7. Place the relearn tool against the tire sidewall, near the valve
stem. Then press the button to
activate the TPMS sensor.
A horn chirp confirms that the
sensor identification code has
been matched to this tire and
wheel position.
8. Proceed to the passenger side front tire, and repeat the
procedure in Step 7. 9. Proceed to the passenger side
rear tire, and repeat the
procedure in Step 7.
10. Proceed to the driver side rear tire, and repeat the procedure
in Step 7. The horn sounds two
times to indicate the sensor
identification code has been
matched to the driver side rear
tire, and the TPMS sensor
matching process is no longer
active. The TIRE LEARNING
ACTIVE message on the DIC
display screen goes off.
11. Turn the ignition to LOCK/OFF or press STOP to turn the
ignition off.
12. Set all four tires to the recommended air pressure
level as indicated on the Tire
and Loading Information label.

Vehicle Care 257
Tire Inspection
We recommend that the tires,
including the spare tire, if the
vehicle has one, be inspected
for signs of wear or damage at
least once a month.
Replace the tire if:
.The indicators at three or
more places around the tire
can be seen.
.There is cord or fabric
showing through the tire's
rubber.
.The tread or sidewall is
cracked, cut, or snagged
deep enough to show cord or
fabric.
.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 Schedule0294.
Tires are rotated to achieve a
more 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 0258 andWheel
Replacement 0262.
Use this rotation pattern when
rotating the tires.
Do not include the compact
spare tire 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 0251 and
Vehicle Load Limits 0163.
Reset the Tire Pressure Monitor
System. See Tire Pressure
Monitor Operation 0253.
