INFLATION

See the tire information label for
your vehicle's tire inflation
specifications.
To determine the location of your
vehicle's tire information label, see
"Vehicle Loading" in Section 3.
The label gives the correct inflation
pressures for your tires when
they're cold. Cold means your
vehicle has been sitting for three
hours or more - or, if driven at all,
for no more than 1.6 km (1 mph).
. . . 300
The air pressure indicated on the
label as "cold" should be
maintained for the tires to perform
properly. However, do not
overload your vehicle. See "Vehicle
Loading" in Section 3.
Maintaining the cold tire pressure
indicated on the tire information
label leads to better fuel economy,
longer tire life, a more comfortable
ride and better overall driveability.
Check your tires at least once a
month. Don't forget your spare
tire.
NOTICE
Improper tire pressure
promotes adverse effects in tire
life and vehicle performance.
Excessively low inflation causes
deflection of the tire and tire
overheating which reduces tire
strength and thus may damage
the tires. It also causes tire
overloading, abnormal wear,
poor driveability, and poor fuel
economy.
Excessively high inflation causes
abnormal tire wear and poor
ride which promotes vehicle
damage due to impact from
road bumps.
