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 provid e the best combination of hand ling, tread life, and comfort.
Refer to the driver’s doorjamb label or spec ifications page for the specified pressure.
Under inflated tires wear unevenly, advers ely affect handling and fuel economy, and
are more likely to fail from overheating.
Overinflated tires make your vehicle ride ha rshly, 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 or before long trips, use a gauge to measure the pressure in all
tires, including the spare. Even tires in good condition can lose 1–2 psi (10–20 kPa,
0.1–0.2 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 side 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. 582
•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.
Whenever tire pressure is adjusted, you must
calibrate the TPMS. 2 TPMS Calibration P. 448
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.
Check the spare tire pressu re once a month or before
long trips.
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.

Maintenance
Tire and Wheel Replacement
Replace your tires with radials of the same size, load range, speed rating, and
maximum cold tire pressure rating (as shown on the tire’s sidewall). Using tires of a
different size or construction can cause ce rtain vehicle systems such as the ABS and
Vehicle Stability Assist
TM (VSA ®) 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.
Make sure that the wheel’s specifications match those of the original wheels.

Installing improper tires on your vehicle can
affect handling and stability. This can cause
a crash in which you can be seriously hurt or

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 maintain sufficient distance between vehicles when driving.
Be particularly careful wh en operating the steering wheel or brakes to prevent
skidding.
Use tire chains, snow tires, or all season tires 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 clea rance, we strongly recommend using the
chains listed below:
• Follow the chain manufactur er’s instruction when installing. Mount them as
tightly as you can.
• Check that the chains do not touc h the brake lines or suspension.
• Drive slowly.

NOTICE
Traction devices that are the 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 equipp ed 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.

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 a firm, level, and n on-slippery surface, and apply the parking
brake.
2. Put the transmission into
(P.
3. Turn on the hazard warning lights an d set the power mode to VEHICLE OFF.
1Changing a Flat Tire
Follow these compact spare precautions:
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.
NOTICE
Do not use the jack if it doesn’t work properly.
Call your dealer or a pr ofessional towing service.
Do not mount the compact spare on the front.
If either front tire goes flat, remove the rear tire on
the same side, and mount the compact spare on the
rear and the rear tire on the front.

1. Remove the center cap.
2. Place the flat tire face down in the spare tire
well.
3. Remove the spacer cone from the wing
bolt, flip it over, and insert it back on the
bolt. Secure the flat tire with the wing bolt.
4. Securely put the jack and wheel nut wrench
back in the tool case. Store the case in the
trunk.
If you replace a flat tire with the spare tire, the low tire pressure/TPMS indicator
