• Be sure to reinstall the tire infla‐
tion valve caps. Without the valve
cap, dirt or moisture could get into
the valve core and cause air leak‐
age. If a valve cap is missing, in‐
stall a new one as soon as possi‐
ble.
WARNING
n Tire Inflation
Overinflation or underinflation can
reduce tire life, adversely affect ve‐
hicle handling, and lead to sudden
tire failure. This could result in loss
of vehicle control and potential in‐
jury.
CAUTION
n Tire pressure
Always observe the following:

• Check tire pressure when the tires
are cold. (After vehicle has been
parked for at least three hours or
hasn't been driven more than
1.6 km (one mile) since startup.)
• Check the pressure of your spare
tire each time you check the pres‐
sure of other tires.
• Never overload your vehicle. Be
careful not to overload a vehicle
luggage rack if your vehicle is
equipped with one.
• Worn, old tires can cause acci‐
dents. If your tread is badly worn,
or if your tires have been dam‐
aged, replace them.
Checking tire inflation pressure
Check your tires once a month or more.
Also, check the tire pressure oý the
spare tire.
How to check
Use a þood quality þauþe to check tire
pressure. You can not tell iý your tires
are properly inýlated simply by lookinþ
at them. Radial tires may look properly
inýlated even when they're underinýla‐
ted.
Check the tire's inýlation pressure when
the tires are cold. - "Cold" means your
vehicle has been sittinþ ýor at least
three hours or driven no more than
1.6 km (1 mile).
Remove the valve cap ýrom the tire
valve stem. Press the tire þauþe ýirmly
onto the valve to þet a pressure meas‐
urement. Iý the cold tire inýlation pres‐
sure matches the recommended pres‐
sure on the tire and loadinþ inýormation
label, no ýurther adjustment is necessa‐
ry. Iý the pressure is low, add air until
you reach the recommended amount.
Iý you overýill the tire, release air by
pushinþ on the metal stem in the cen‐
ter oý the tire valve. Recheck the tire
pressure with the tire þauþe. Be sure to
put the valve caps back on the valve
stems. They help prevent leaks by
keepinþ out dirt and moisture.
WARNING
• Inspect your tires frequently for
proper inflation as well as wear
and damage. Always use a tire
pressure gauge.
