Inflation - Tire Pressure

If your vehicle is a Two mode Hybrid, see the
Two mode Hybrid manual for more information.
Tires need the correct amount of air pressure to
operate effectively.
Do not let anyone tell you that
Notice:
under inflation or over inflation is all right.
It is not. If your tires do not have enough air
(under inflation), you can get the following:
Too much flexing
Too much heat
Tire overloading
Premature or irregular wear
Poor handling
Reduced fuel economy
If your tires have too much air (over inflation),
you can get the following:
Unusual wear
Poor handling
Rough ride
Needless damage from road hazards

A vehicle specific Tire and Loading Information
label is attached to your vehicle. This label shows
your vehicle's original equipment tires and the
correct inflation pressures for your tires when they
are cold. The recommended cold tire inflation
pressure, shown on the label, is the minimum
amount of air pressure needed to support your
vehicle's maximum load carrying capacity.
For additional information regarding how much
weight your vehicle can carry, and an example
of the Tire and Loading Information label, see
Loading the Vehicle on page 5 31. How you load
your vehicle affects vehicle handling and ride
comfort. Never load your vehicle with more weight
than it was designed to carry.
When to Check
Check your tires once a month or more.
Do not forget to check the pressure of the spare
tire. SeeSpare Tire on page 6 107 for additional
information.
