Checking and Maintaining Tires
Checking Tires
To safely operate your vehicle, your tires must be of the proper type and size, in
good condition with adequate tread, and properly inflated.
■Inflation guidelines
Properly inflated tires provide the best combination of handling, tread life, and comfort.
Refer to the driver’s doorjamb label or spec ification’s page for the specified pressure.
Underinflated tires wear unevenly, adversely affect handling and fuel economy, and
are more likely to fail from overheating.
Overinflated tires make your vehicle ride harshly, are more prone to road hazards,
and wear unevenly.
Every day before you drive, look at each of the tires. If one looks lower than the
others, check the pressure with a tire gauge.
At least once a month and before long trip s, use a gauge to measure the pressure in
all tires, including the spare. Even tires in good condition can lose 1 to 2 psi (10 to
20 kPa, 0.1 to 0.2 kgf/cm
2) per month.
■Inspection guidelines
Every time you check inflation, also examine the tires and valve stems.
Look for:
• Bumps or bulges on the side or in the tread. Replace the tire if you find any cuts,
splits, or cracks in the si de of the tire. Replace it if you see fabric or cord.
• Remove any foreign objects and inspect for air leaks.
• Uneven tread wear. Have a deal er check the wheel alignment.
• Excessive tread wear.
2 Wear Indicators P. 381
•Cracks or other damage around valve stem.
1Checking Tires
Measure the air pressure when tires are cold. This
means the vehicle has been parked for at least three
hours, or driven less than 1 mile (1.6 km). If
necessary, add or releas e air until the specified
pressure is reached.
If checked when hot, tire pressure can be as much as
4–6 psi (30–40 kPa, 0.3–0.4 kgf/cm
2) higher than if
checked when cold.
Have a dealer check the tires if you feel a consistent
vibration while driving. Ne w tires and any that have
been removed and reinst alled should be properly
balanced.
3WARNING
Using tires that are excessively worn or
improperly inflated can cause a crash in
which you can be seriously hurt or killed.
Follow all instruction s in this owner’s
manual regarding ti re inflation and
maintenance.

uuChecking and Maintaining Tires uDOT Tire Quality Grading (U.S. Vehicles)
380
Maintenance
The traction grades, from highest to lowest, are AA, A, B, and C.
Those grades represent the tire’s ability to stop on wet pavement
as measured under controlled conditions on specified
government test surfaces of asph alt and concrete. A tire marked
C may have poor traction performance.
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 h eat 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 temp erature 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 Vehicle
Safety Standard No. 109. Grades B and A represent higher levels
of performance on the laboratory test wheel than the minimum
required by law.
■Traction
■Temperature
1 Traction
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.
1Temperature
Warning: The temperature grade for
this tire is establishe d 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.

Maintenance
Tire and Wheel Replacement
Replace your tires with radials of the sa me size, load range, speed rating, and
maximum cold tire pressure ra ting (as shown on the tire’s sidewall). Using tires of a
different size or construction can cause the ABS, vehicle stability assist (VSA ®), hill
start assist, and the All-Wheel Drive (AWD) with intelligent control system
* to work
incorrectly.
It is best to replace all four tires at the same time. If that isn’t possible, replace the
front or rear tires in pairs.
If you replace a wheel, only use TPMS sp ecified wheels approved for your vehicle.
Make sure that the wheel’s specifications match those of the original wheels.

3WARNING
Installing improper tires on your vehicle can
affect handling and stability. This can cause
a crash in which you can be seriously hurt or
killed.
Always use the size and type of tires
recommended in this owner’s manual.

Maintenance
Winter Tires
If driving on snowy or frozen roads, mount all season marked “M+S” tires, snow
tires, or tire chains; reduce speed; and ma intain sufficient distance between vehicles
when driving.
Be particularly careful when operating the steering wheel or brakes to prevent
skidding.
Use tire chains, snow tires, or all season ti res when necessary or according to the law.
When mounting, refer to the following points.
For winter tires:
• Select the size and load ranges that are the same as the original tires.
• Mount the tires to all four wheels.
For tire chains:
• Install them on the front tires only.
• Because your vehicle has limited tire clearance, we strongly recommend using the
chains listed below:
• Follow the chain manufacturer’s instruction when installing. Mount them as
tightly as you can.
• Check that the chains do not to uch the brake lines or suspension.
• Drive slowly.
Cable-type: SCC Radial Chain TC2212MM
1Winter Tires
NOTICE
Traction devices that are th e wrong size or improperly
installed can damage your vehicle’s brake lines,
suspension, body, and wheels. Stop driving if they are
hitting any part of the vehicle.
When tire chains are mounted, follow the chain
manufacturer’s instructi ons regarding vehicle
operational limits.
If your vehicle is equipped with summer tires, be
aware that these tires are not designed for winter
driving conditions. For more information, contact a
dealer.
3WARNING
Using the wrong chains, or not properly
installing chains, can damage the brake
lines and cause a crash in which you can be
seriously injured or killed.
Follow all instruction s in this owner’s
manual regarding the selection and use of
tire chains.

Maintenance
A good coat of automotive body wax helps protect your vehicle’s paint from the
elements. Wax will wear off over time an d expose your vehicle’s paint to the
elements, so reapply as necessary.
If you get gasoline, oil, engine coolant, or battery fluid on resin coated parts, they
may be stained or the coating may peel. Prom ptly wipe it away using a soft cloth and
clean water.
Wipe using a glass cleaner.
Aluminum is susceptible to deteriorat ion caused by salt and other road
contaminants. Use a sponge and mild detergent to wipe away promptly.
Be careful not to use harsh chemicals (inc luding some commercial wheel cleaners) or
a stiff brush. They can damage the clear coat of the aluminum alloy wheels that
helps keep the aluminum from corroding and tarnishing.

Handling the Unexpected
If a Tire Goes Flat
Changing a Flat Tire*
If a tire goes flat while driving, grasp the steering wheel firmly, and brake gradually
to reduce speed. Then, stop in a safe plac e. Replace the flat tire with a compact
spare tire. Go to a dealer as soon as possib le to have the full-size tire repaired or
replaced.
1. Park the vehicle on firm, level, non-slip pery surface and apply the parking brake.
2. Move the shift lever to
(P.
3. Turn on the hazard warning lights and set the power mode to VEHICLE OFF
(LOCK).
1Changing a Flat Tire*
Periodically check the tire pressure of the compact
spare. It should be set to the specified pressure.
Specified Pressure: 60 psi (420 kPa, 4.2 kgf/cm
2)
When driving with the compact spare tire, keep the
vehicle speed under 50 mph (80 km/h). Replace with
a full-size tire as soon as possible.
The compact spare tire and wheel in your vehicle are
specifically for this model. Do not use them with
another vehicle. Do not us e another type of compact
spare tire or wheel with your vehicle.
Do not mount tire chains on a compact spare tire.
If a chain-mounted front tire goes flat, remove one of
the full-size rear tires and replace it with the compact
spare tire. Remove the flat front tire and replace it
with the full-size tire that was removed from the rear.
Mount the tire chains on the front tire.
Do not use a puncture-repairi ng agent on a flat tire,
as it can damage the tire pressure sensor.
