10. After hearing the confirming single horn chirp forthe driver side rear tire, a double horn chirp will
sound to signal the tire matching mode is no longer
active. Press the push‐button ignition switch
to Acc.
11. Set all four tires to the recommended air pressure level as indicated on the tire and loading
information label.
12. Put the valve caps back on the valve stems.
Tire Inspection and Rotation
We recommend that you regularly inspect your
vehicle's tires, including the spare tire, for signs of
wear or damage. See When It Is Time for New
Tires
on page 6‑67for more information.
Always remove the tires if any of the following
statements are true:
.You can see the indicators at three or more
places around the tire.
.You can see 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 is not recommended if your vehicle
has P235/50ZR18 size tires on the front wheels
and P255/45ZR18 size tires on the rear wheels.
Different tire sizes should not be rotated front to
rear. Each tire and wheel should only be used in
the original front or rear position it is in.
Tire rotation is recommended if the vehicle is
equipped with P235/50R17 size tires on all four
wheel positions or 255/45ZR18 size tires on all
four wheel positions. These tires should be
rotated every 12 000 km (7,500 miles). See
Scheduled Maintenance
on page 7‑3.
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.
Any time you notice unusual wear, rotate your
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 6‑67
and Wheel Replacementon page 6‑72.

A tire marked C may have poor traction
performance. Warning: The traction grade
assigned to this tire is based on straight-ahead
braking traction tests, and does not include
acceleration, cornering, hydroplaning, or peak
traction characteristics.
Temperature–A, B, C
The temperature grades are A (the highest), B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate heat
when tested under controlled conditions on a
specified indoor laboratory test wheel. Sustained
high temperature can cause the material of the
tire to degenerate and reduce tire life, and
excessive temperature can lead to sudden tire
failure. The grade C corresponds to a level of
performance which all passenger car tires must
meet under the Federal Motor Safety Standard
No. 109. Grades B and A represent higher levels
of performance on the laboratory test wheel than
the minimum required by law. Warning: The
temperature grade for this tire is established for a
tire that is properly inflated and not overloaded.
Excessive speed, underinflation, or excessive
loading, either separately or in combination, can
cause heat buildup and possible tire failure.
Wheel Alignment and Tire Balance
The tires and wheels on your vehicle were aligned and
balanced carefully at the factory to give you the longest
tire life and best overall performance. Adjustments
to wheel alignment and tire balancing will not be
necessary on a regular basis. However, if you notice
unusual tire wear or your vehicle pulling to one side or
the other, the alignment might need to be checked.
If you notice your vehicle vibrating when driving on a
smooth road, the tires and wheels might need to be
rebalanced. See your dealer for proper diagnosis.
Wheel Replacement
Replace any wheel that is bent, cracked, or badly
rusted or corroded. If wheel nuts keep coming loose,
the wheel, wheel bolts, and wheel nuts should be
replaced. If the wheel leaks air, replace it (except some
aluminum wheels, which can sometimes be repaired).
See your dealer if any of these conditions exist.
Your dealer will know the kind of wheel you need.
Each new wheel should have the same load-carrying
capacity, diameter, width, offset, and be mounted the
same way as the one it replaces.
