Tire Information
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 the specifications (see page 138) 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.
•  Measure the air pressure when tires are cold. This means the vehicle has been parked for
at least 3 hours, or driven less than 1 mile (1.6 km). If necessary, add or release air until
the specified pressure is reached. If checked when hot, tire pressure can be as much as
4-6 psi (30-40 kPa, 0.3-0.5 kgf/cm
2) higher than checked when cold.
•  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 inflate the tires, check for the following:
•  Any damage to tires, including bumps, bulges, cuts, splits, or cracks in the side or tread.
Remove any foreign objects and inspect for air leaks. Replace tires if you see fabric or
cord.
•  Uneven or excessive tread wear. Have a dealer check the wheel alignment.
•  Cracks or other damage around the valve stems.
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 low that the indicator is exposed, replace the tire. Worn out
tires have poor traction on wet roads.

Tire and Loading Information LabelThe label attached to the driver’s doorjamb provides necessary tire and loading
information. Using tires that are excessively worn or improperly inflated can cause
a crash in which you can be seriously hurt or killed.
Follow all instructions in this owner’s guide regarding tire inflation
and maintenance.

Tire and Wheel r eplacement
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 certain vehicle systems 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 change or replace a wheel, make sure that the wheel’s specifications match those
of the original wheels. Only use TPMS-specified wheels approved for your vehicle.
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 the Owner’s Manual.

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.
Winter Tires
If driving on snowy or frozen roads, mount all season tires marked “M+S”, snow tires, or
tire chains; reduce speed; and maintain sufficient distance between vehicles when driving.
For winter tires, select the size and load ranges that are the same as the original tires, and
mount them to all four wheels.
Tire Chains
Install tire chains on the front tires only. Because your vehicle has limited tire clearance,
we strongly recommend using the following chains: Cable type: SCC Cable Chain ZT735.
Mount chains as tightly as you can, and make sure that they do not touch the brake lines
or suspension.
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 guide regarding the selection and use of tire
chains.
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.

Tire Labeling
The tires that came on your vehicle have a number of markings. Those you should
be aware of are described below.
Tire Identification Number (TIN)
The tire identification number (TIN)
is a group of numbers and letters that
look like the example shown. TIN is
located on the sidewall of the tire.
Glossary of Tire Terminology
Cold Tire Pressure – The tire air pressure when the vehicle has been parked for at
least three hours or driven less than 1 mile (1.6 km).
Load Rating – The maximum load that a tire is rated to carry for a given inflation
pressure.
Maximum Inflation Pressure – The maximum tire air pressure that the tire can
hold.
Maximum Load Rating – The load rating for a tire at the maximum permissible
inflation pressure for that tire.
Recommended Inflation Pressure – The cold tire inflation pressure recommended
by the manufacturer.
Treadwear Indicators (TWI) – The projections within the principal grooves
designed to give a visual indication of the degrees of wear of the tread.
DO T B97R FW6X 2209
DOT: This indicates that the tire meets all
requirements of the
U.S. Department of Transportation.
B97R: Manufacturer’s identication mark.

Tire Pressure monitoring System (TPmS) - r equired Federal explanation
Each tire, including the spare (if provided), should be checked monthly when cold
and inflated to the inflation pressure recommended by the vehicle manufacturer
on the vehicle placard or tire inflation pressure label.
(If your vehicle has tires of a different size than the size indicated on the vehicle
placard or tire inflation pressure label, you should determine the proper tire
inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire pressure
monitoring system (TPMS) that illuminates a low tire pressure telltale
when one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illuminates, you
should stop and check your tires as soon as possible, and inflate them
to the proper pressure.
Driving on a significantly under-inflated tire causes the tire to overheat and can
lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire maintenance, and it is
the driver’s responsibility to maintain correct tire pressure, even if under-inflation
has not reached the level to trigger illumination of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate
when the system is not operating properly. The TPMS malfunction indicator
is combined with the low tire pressure telltale. When the system detects a
malfunction, the telltale will flash for approximately one minute and then remain
continuously illuminated. This sequence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the system may not be able to
detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of reasons, including the installation
of replacement or alternate tires or wheels on the vehicle that prevent the TPMS
from functioning properly.
Always check the TPMS malfunction telltale after replacing one or more tires
or wheels on your vehicle to ensure that the replacement or alternate tires and
wheels allow the TPMS to continue to function properly.
Testing of readiness Codes
Your vehicle has “Readiness Codes” as part of the onboard self-diagnostic system. Some
states refer to these codes as a test to see if your vehicle’s emissions components are
working properly. The codes may not be read if you go through the testing just after the
battery has gone dead or been disconnected.
To check if they are set, set the power mode to ON without starting the engine. The
malfunction indicator lamp will come on for several seconds. If it goes off, the readiness
codes are set. If it blinks five times, the readiness codes are not set.
If you are required to have your vehicle tested before the readiness codes are set, prepare
the vehicle for retesting by doing the following:
1. Fill the gas tank to approximately 3/4 full.
2. Park the vehicle and leave the engine off for 6 hours or more.
3. Make sure the ambient temperature is between 40°F and 95°F (4°C and 35°C).
4. Start the engine without touching the accelerator pedal, and let it idle for 20 seconds.
5. Keep the vehicle in Park (P). Increase the engine speed to 2,000 rpm, and hold it there
for about 3 minutes.
6. Let the engine idle with your foot off the accelerator for 20 seconds.
7. Select a nearby, lightly traveled major highway where you can maintain a speed of 50 to
60 mph (80 to 97 km/h) for at least 20 minutes. Drive on the highway with the vehicle
in Drive. Do not use cruise control. When traffic allows, drive for 90 seconds without
using the accelerator pedal. (Vehicle speed may vary slightly; this is OK.) If you cannot
do this for a continuous 90 seconds because of traffic conditions, drive for at least 30
seconds, then repeat two more times (for a total of 90 seconds).
8. Drive in city/suburban traffic for at least 10 minutes. When traffic conditions allow, let
the vehicle coast for several seconds without using the accelerator pedal or the brake
pedal.
9. Park the vehicle and leave the engine off for 30 minutes.
The readiness codes are erased when the battery is disconnected, and set again only after
several days of driving under a variety of conditions.
If a testing facility determines that the readiness codes are not set, you may be requested
to return at a later date to complete the test, or see your dealer.
