TPMS (Tire Pressure Monitoring System)
Monitors the tire pressure while you are 
driving. If your vehicle’s tire pressure becomes 
significantly low, the low tire pressure 
indicator comes on.
1TPMS (Tire Pressure Monitoring System)
Conditions such as low ambient temperature and 
altitude change directly affect tire pressure and can 
trigger the low tire pressure indicator to come on.
2If the Low Tire Pressure Indicator Comes 
On P. 537
Tire pressure checked and inflated in:•Warm weather can become under-inflated in 
colder weather.•Cold weather can become over-inflated in warmer 
weather.
The low tire pressure indicator will not come on as a 
result of over inflation.

Driving
Tire Pressure Monitoring System (TPMS) - Required Federal ExplanationEach 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.U.S. models

uuWhen DrivinguTire Pressure Monitoring System (TPMS) - Required Federal Explanation
Driving
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 provided by a separate telltale, 
which displays the symbol “TPMS” when illuminated.
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.

Checking and Maintaining TiresChecking TiresTo 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 specification’s page 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.
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 to 2 psi (10 to 
20 kPa, 0.1 to 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 dealer check the wheel alignment.
•Excessive tread wear.2Wear Indicators P. 502
•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 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, 0.3–0.4 kgf/cm
2) higher than if 
checked when cold.
Have a dealer check the tires if you feel a consistent 
vibration while driving. New tires and any that have 
been removed and reinstalled should be properly 
balanced.

WARNING
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 
manual regarding tire inflation and 
maintenance.

The tire identification number (TIN) is a group of numbers and letters that look like 
the example in the side column. TIN is located on the sidewall of the tire.
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 – Means 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 – Means 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) – Means the projections within the principal grooves 
designed to give a visual indication of the degrees of wear of the tread.■Tire Identification Number (TIN)■Glossary of Tire Terminology

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.
