Maintenance
Wear Indicators
The groove where the wear indicator is
located is 1/16 inch (1.6 mm) shallower than
elsewhere on the tire. If the tread has worn so
that the indicator is exposed, replace the tire.
Worn out tires have poor traction on wet
roads.
Tire Service LifeThe life of your tires is dependent on many factors, including driving habits, road
conditions, vehicle loading, inflation pressure, maintenance history, speed, and
environmental conditions (even when the tires are not in use).
In addition to regular inspections and inflation pressure maintenance, it is
recommended that you have annual inspections performed once the tires reach five
years old. All tires, including the spare
*, should be removed from service after 10
years from the date of manufacture, regardless of their condition or state of wear.
1Checking Tires
High speed driving
We recommend that you do not drive faster than the
posted speed limits and conditions allow. If you drive
at sustained high speeds (models with P245/45R18
96V tires: over 112 mph or 180 km/h, models with
245/40R19 98W tires: over 118 mph or 190 km/h),
adjust the cold tire pressures as shown below to
avoid excessive heat build up and sudden tire failure.Tire Size

uuChecking and Maintaining TiresuTire and Wheel Replacement
Maintenance
Tire and Wheel ReplacementReplace 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 the ABS and vehicle stability assist (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.
If you replace a wheel, only use TPMS specified wheels approved for your vehicle.

WARNING
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.

uuChecking and Maintaining TiresuWinter Tires
Maintenance
Winter TiresIf 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 when 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 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 touch the brake lines or suspension.
•Drive slowly.Cable-type: SCC Radial Chain SC1040
1Winter TiresNOTICETraction 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 instructions 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.

WARNING
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 instructions in this owner’s
manual regarding the selection and use of
tire chains.

uuIf a Tire Goes FlatuChanging a Flat Tire
Handling the Unexpected
Changing a Flat TireIf a tire goes flat while driving, grasp the steering wheel firmly, and brake gradually
to reduce speed. Then, stop in a safe place. Replace the flat tire with a compact
spare tire. Go to a dealer as soon as possible to have the full-size tire repaired or
replaced.
1.Park the vehicle on firm, level, and non-slippery and apply the parking brake.
2.Move the shift lever to

.
3.Turn on the hazard warning lights and set the power mode to VEHICLE OFF
(LOCK).
Vehicles with optional spare tire kit
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 use 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.

uuIf a Tire Goes FlatuChanging a Flat Tire
Handling the Unexpected
1.Place the flat tire face down in the spare tire
well.
2.Wrap the spacer cone and spare tire wing
bolt with cloth or paper, and store them in
the spare tire well.
3.Store the jack and tools in the tool case.
Place the tool case on the flat tire.
4.Lower the trunk floor lid, then close the
trunk.
If you replace a flat tire with the spare tire, the low tire pressure/TPMS indicator
comes on while you are driving. After driving for a few miles (kilometers), the
indicator will start blinking for a short time and then stay on. Tire Pressure
Monitor Problem/CHECK TPMS SYSTEM appears on the multi-information
display, but this is normal.
If you replace the tire with a full-size tire, the warning message on the multi-
information display and the low tire pressure/TPMS indicator will go off after a few
miles (kilometers).

Handling the Unexpected
If the Low Tire Pressure/TPMS Indicator Comes On or Blinks
■Reasons for the indicator to come on or blink
A tire pressure is significantly low. If there is a problem with the TPMS or
the compact spare tire
* is installed, the indicator blinks for about one
minute, and then stays on.
■What to do when the indicator comes on
Stop your vehicle in a safe place. Check the tire pressure and adjust the
pressure to the specified level. The specified tire pressure is on a label on
the driver’s side doorjamb.■What to do when the indicator blinks
Have the tire inspected by a dealer as soon as possible. If the compact
spare tire
* causes the indicator to blink, change the tire to a full-size tire.
The indicator goes off after driving for a few miles (kilometers).
1If the Low Tire Pressure/TPMS Indicator Comes On or BlinksNOTICEDriving on an extremely underinflated tire can cause
it to overheat. An overheated tire can fail. Always
inflate your tires to the prescribed level.
