underinflated and overinflated tires
Underinflated tires
G WARNING
Follow recommended tire inflation pres-
sures.
Do not underinflate tires. Underinflated
tires wear excessively and/or unevenly,
adversely affect handling and energy con-
sumption of the vehicle, and are more
likely to fail from being overheated.

Do not overinflate tires. Overinflated
tires can adversely affect handling and

stopping distance, and result in sudden
deflation (blowout) because they are more
likely to become punctured or damaged by

Do not overload the tires by exceeding the
specified load limit as indicated on the
Tire and Loading Information placard on
the driver's door B‑pillar. Overloading the
tires can overheat them, possibly causing
a blowout. Overloading the tires can also
result in handling or steering problems, or
brake failure.
Check the tire inflation pressure at least
once a month.
Check and adjust the tire inflation pres-
sure when the tires are cold (
Checking tire inflation pressure man-
ually
Follow the steps below to achieve correct
