Tire Rotation
Tires should be rotated
every 12 000 km (7,500 mi).
SeeMaintenance Schedule on
page 11‑3.
Tires are rotated to achieve a
uniform wear for all tires.
The first rotation is the most
important.
Any time unusual wear is
noticed, rotate the tires as soon
as possible and check the
wheel alignment. Also check
for damaged tires or wheels.
See When It Is Time for New
Tires on page 10‑71 andWheel
Replacement on page 10‑77.
If your vehicle has dual rear
wheels, also see Dual Tire
Rotation on page 10‑71.
Use this rotation pattern when
rotating the tires if the vehicle
has single rear wheels.Use this rotation pattern when
rotating the tires if the vehicle
has dual rear wheels (except
polished forged aluminum
wheels).
Vehicles with polished forged
aluminum dual wheels have
three unique wheels; a front, a
rear outer and a rear inner.
These wheels cannot be rotated
to another position, however,
they can be rotated from left to
right to the same position.

10-76 Vehicle Care
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 were aligned
and balanced at the factory to
provide the longest tire life and best
overall performance. Adjustments to
wheel alignment and tire balancing
will not be necessary on a regular
basis. However, check the
alignment if there is unusual tire
wear or if the vehicle is pulling to
one side or the other. If the vehicle
vibrates when driving on a smooth
road, the tires and wheels might
need to be rebalanced. See your
dealer for proper diagnosis.

replaced include three or more
visible treadwear indicators; cord
or fabric showing through the
rubber; cracks or cuts in the
tread or sidewall; or a bulge or
split in the tire.
.Trained dealer technicians can
inspect and recommend the
right tires. Your dealer can also
provide tire/wheel balancing
services to ensure smooth
vehicle operation at all speeds.
Your dealer sells and services
name brand tires.Vehicle Care

Interior Care on
page 10‑105 andExterior Care on
page 10‑102.
Wheel Alignment
Wheel alignment is critical for
ensuring that the tires deliver
optimal wear and performance.
.Signs that the alignment may
need to be adjusted include
pulling, improper vehicle
handling, or unusual tire wear.
.Your dealer has the required
equipment to ensure proper
wheel alignment. Windshield
For safety, appearance, and the
best viewing, keep the windshield
clean and clear.
.Signs of damage include
scratches, cracks, and chips.
.Trained dealer technicians can
inspect the windshield and
recommend proper replacement
if needed.
Wiper Blades
