Inflation labels
Tire inflation placard on U.S. models
Check tire inflation pressure regularly.
Tables listing the recommended inflation pres-
sure for your vehicle can be found on page
172. A tire inflation pressure placard is also
located on the driver's side B-pillar (the struc-
tural member at the side of the vehicle, at the
rear of the driver's door opening). This placard
indicates the designation of the factory-moun-
ted tires on your vehicle, as well as load limits
and inflation pressure.

NOTE
The placards shown indicate inflation pres-
sure for the tires installed on the car at the
factory only.
Use a tire gauge to check the tire inflation pres-
sure, including the spare, at least once a month
and before long trips. You are strongly urged
to buy a reliable tire pressure gauge, as auto-
matic service station gauges may be inaccu-
rate.
Use the recommended cold inflation pressure
for optimum tire performance and wear.
Under-inflation or over-inflation may cause
uneven treadwear patterns.
WARNING
• Under-inflation is the most common
cause of tire failure and may result in
severe tire cracking, tread separation,
or "blowout," with unexpected loss of
vehicle control and increased risk of
injury.
• Under-inflated tires reduce the load car-
rying capacity of your vehicle.
When weather temperature changes occur, tire
inflation pressures also change. A 10-degree
temperature drop causes a corresponding
drop of 1 psi (7 kPa) in inflation pressure. Check
your tire pressures frequently and adjust them
to the proper pressure, which can be found on
the vehicle's tire information placard or certifi-
cation label.
