Maintenance
DOT Tire Quality Grading (U.S. Vehicles) The tires on your vehicle m eet all U.S. Federal Safety
Requirements. All tires are also graded for treadwear, traction,
and temperature performance according to Department of
Transportation (DOT) standards. The following explains these
gradings.
Quality grades can be found where applicable on th e tire sidewall
between tread shoulder and maximum section width.
The treadwear grade is a comparative rating based on the wear
rate of the tire when tested un der controlled conditions on a
specified government test course. For example, a tire graded 150
would wear one and one-half (1 1/2) times as well on the
government course as a tire graded 100. The relative performance
of tires depends upon the actual co nditions of their use, however,
and may depart significantly from the norm due to variations in
driving habits, service practi ces and differences in road
characteristics and climate.■ Uniform Tire Quality Grading

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. 1 Temperature
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.

647uu Checking and Maintaining Tires u Wear Indicators
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 ex posed, replace the tire.
Worn out tires have po or 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 wh en 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, regardle ss of their condition or state of wear. 1 Checking 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 (over 99 mph or 160 km/h),
adjust the cold tire pressures as shown below to
avoid excessive heat build up and sudden tire failure.

648 uu Checking and Maintaining Tires u Tire and Wheel Replacement
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 ce rtain vehicle systems such as 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 thos e of the original wheels. 1 Tire and Wheel Replacement

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.

649uu Checking and Maintaining Tires u Tire Rotation
Maintenance
Tire Rotation Rotating tires according to the maintena nce messages on the driver information
interface 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. 1 Tire Rotation
Tires with directional trea d patterns should only be
rotated front to back (not fr om one side to the other).
Directional tires should be mounted with the rotation
indication mark facing forward, as shown below.
Whenever tires are rotated, you must calibrate the
TPMS.

650 uu Checking and Maintaining Tires u Winter Tires
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 sufficie nt 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 Ra dial Chain SC1036
Not recommended to use any type of chains 1 Winter 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 equipp ed with summer tires, be
aware that these tires are not designed for winter
driving conditions. For more information, contact a
dealer.3
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 instruction s in this owner’s
manual regarding the selection and use of
tire chains.

Handling the Unexpected
If a Tire Goes FlatChanging 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 non-slippery surface, and apply the parking
brake.
2. Put the transmission into ( P
.
2. Move the shift lever to ( R
.
3. Turn on the hazard warning lights and set the power mode to VEHICLE OFF. 1 Changing 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.Automatic transmission/Continuousl y variable transmission models

686 uu Indicator, Coming On/Blinking u If the Low Tire Pressure/TPMS Indicator Comes On or Blinks
Handling the Unexpected If the Low Tire Pressure/TPMS Indicator Comes On or
Blinks ■ Reasons for the indicato r to come on or blink
A tire pressure is significantly low, or the TPMS has not been calibrated.
If there is a problem with the TPMS, the indicator blinks for about one
minute, and then stays on.
If the compact spare tire is installed, the indicator will either come on or
it will first blink for abou t one minute, then stay on.
■ What to do when the indicator comes on
Drive carefully and avoid abrupt cornering and hard braking.
Stop your vehicle in a safe place. Ch eck the tire pressure and adjust the
pressure to the specified level. The sp ecified tire pressure is on a label on
the driver side doorjamb.
u Calibrate the TPMS after the tire pressure is adjusted. 2 TPMS Calibration P. 497
If the compact spare tire causes the indicator to come on, change the
tire to a full-size tire. The indica tor goes off after calibrating the TPMS.
■ What to do when the indicator blinks, then remains on
Have the tire inspected by a dealer as soon as possible. If the compact
spare tire causes the indicator to first blink, and then stay on, change the
tire to a full-size tire. The indica tor goes off after calibrating the TPMS.2 TPMS Calibration P. 497 1 If the Low Tire Pressure/TPMS Indicator Comes On or BlinksNOTICE
Driving on an extremely unde rinflated tire can cause
it to overheat. An overheated tire can fail. Always
inflate your tires to the prescribed level.
