Checking tire inflation pressure
Check and adjust the tire inflation pressure
when the tires are cold. The tires can be
considered cold if the vehicle has been
parked for at least 3 hours or driven less than
1 mile (1.6 km).
If you check the tire inflation pressure when
the tires are warm (the vehicle has been
driven for several miles or sitting less than

G Warning!
Follow recommended tire inflation
pressures.
Do not overinflate tires. Overinflated tires
can adversely affect handling and ride
comfort, wear unevenly, increase stopping
distance, and result in sudden deflation
(blowout) because they are more likely to
become punctured or damaged by road
debris, potholes etc.
Do not underinflate tires. Underinflated
tires wear excessively and/or unevenly,
adversely affect handling and fuel
economy, and are more likely to fail from
being overheated.

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.

This is normal. Do not let air out to match the
specified cold tire inflation pressure.
Otherwise, the tire will be underinflated.
Checking tire inflation pressure
manually
Follow the steps below to achieve correct tire
inflation pressure:
X Remove the cap from the valve on one tire.
X Firmly press a tire gauge onto the valve.
