Standard inflation pressure
• A sign affixed to the driver’s door B-pillar indi-
cates standard inflation pressure.
CAUTION
Always install the valve caps after checking or
adjusting air pressure. Unless the valve caps
are in place, dirt and dust may stick in the
valves and cause a flat tire.
• Tire temperatures rise during use, increasing
the tire pressure. This is normal; do not release
air from the tires when they are hot.
• Tire pressure drops naturally over time. Check
the tire pressure at least once a month, using an
air gauge.
• Pay particularly close attention to the air pres-
sure in new tires. New tires tend to expand
slightly, with a corresponding decrease in air
pressure.
• On dual wheels, inflate both inner and outer tires
to the same pressure.
• It is not necessary to increase tire pressure
before high-speed driving.

WARNING
• Inflate tires to the standard inflation pres-
sure. Tire underinflation or overinflation
will damage wheels and tires, and could
result in a blowout, causing possible per-
sonal injury and property damage.
• Handle tires with care. During the initial
tire inflation, there is the possibility of an
explosion, causing serious personal injury
and loss of life.
