In¯ation -- Tire Pressure
The Tire-Loading Information label, which is on the
inside of the trunk lid, shows the correct in¯ation
pressures for your tires when they're cold. ªColdº means
your vehicle has been sitting for at least three hours
or driven no more than 1 mile (1.6 km).
Notice:Don't let anyone tell you that underin¯ation
or overin¯ation is all right. It's not. If your tires
don't have enough air (underin¯ation), you can get
the following:
·Too much ¯exing
·Too much heat
·Tire overloading
·Bad wear
·Bad handling
·Bad fuel economyIf your tires have too much air (overin¯ation),
you can get the following:
·Unusual wear
·Bad handling
·Rough ride
·Needless damage from road hazards
When to Check
Check your tires once a month or more.
Don't forget your compact spare tire. It should be at
60 psi (420 kPa).
How to Check
Use a good quality pocket-type gage to check tire
pressure. You can't tell if your tires are properly in¯ated
simply by looking at them. Radial tires may look
properly in¯ated even when they're underin¯ated.
Be sure to put the valve caps back on the valve stems.
They help prevent leaks by keeping out dirt and moisture.

CAUTION: (Continued)
Stop somewhere as soon as you can and have
the nuts tightened with a torque wrench to the
proper torque speci®cation. See ªCapacities
and Speci®cationsº in the Index for wheel nut
torque speci®cation.
Notice:Improperly tightened wheel nuts can lead
to brake pulsation and rotor damage. To avoid
expensive brake repairs, evenly tighten the wheel
nuts in the proper sequence and to the proper torque
speci®cation. See ªCapacities and Speci®cationsº in
the index for the wheel nut torque speci®cation.

Storing the Flat Tire and Tools
{CAUTION:
Storing a jack, a tire, or other equipment in the
passenger compartment of the vehicle could
cause injury. In a sudden stop or collision,
loose equipment could strike someone.
Store all these in the proper place.
After you've put the compact spare tire on your vehicle,
you'll need to store the ¯at tire in the trunk. Use the
following procedure to secure the ¯at tire in the trunk.
When storing a full-size tire, you must use the extension
to help avoid wheel surface damage. Use the extension
and protector/guide located in the foam holder. To store a
full-size tire, place the tire in the trunk valve stem facing
down, with the protector/guide placed through a wheel
bolt hole. Remove the protector and attach the retainer
securely. When putting the compact spare back in the
trunk, place the protector/guide back in the foam holder.
Store the cover as far forward as possible.
