uuChecking and Maintaining TiresuWear Indicators
Maintenance
Wear IndicatorsThe 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 Life
The 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.

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 the ABS and VSA® (vehicle stability assist)
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.

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
Tire Rotation
Rotating tires according to the maintenance messages on the multi-information
display helps to distribute wear more evenly and increase tire life. ■Tires without rotation marks
Rotate the tires as shown here.
■ Tires with rotation marks
Rotate the tires as shown here.
1Tire Rotation
Tires with directional tread patterns should only be
rotated front to back (not from one side to the other).
Directional tires should be mounted with the rotation
indication mark facing forward, as shown below.

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 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 SC1030

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 instructions regarding vehicle operational limits.
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 instruc tions in this owner's
manual regarding the selection and use of
tire chains.

Climate Control System Maintenance
Dust and Pollen Filter
The Climate Control system is equipped with a dust and pollen filter that collects
pollen, dust, and other debris in the air. The Maintenance MinderTM
messages will let
you know when to replace the filter.
We recommend that you replace the dust and pollen filter sooner when using your
vehicle in areas with high concentrations of dust.
1Dust and Pollen Filter
If the airflow from the climate control system
deteriorates noticeably, and the windows fog up
easily, the filter may need to be replaced. Please
contact a dealer for replacement.

1Interior Care
Do not spill liquids inside the vehicle.
Electrical devices and systems may malfunction if
liquids are splashed on them.
Do not use silicone based sprays on electrical devices
such as audio devices and switches.
Doing so may cause the items to malfunction or a fire
inside the vehicle.
If a silicone based spray is inadvertently used on
electrical devices, consult a dealer.
Depending on their composition,
chemicals and
liquid aromatics may cause discoloration, wrinkles,
and cracking to resin-based parts and textiles.
Do not use alkali solvents or organic solvents such as
benzene or gasoline.
After using chemicals, make sure to gently wipe them
off using a dry cloth.
Do not place used cloths on top of resin based parts
or textiles for long periods of time without washing.
