{WARNING:
Rust or dirt on a wheel, or on the parts to which it
is fastened, can make wheel nuts become loose
after time. The wheel could come off and cause
an accident. When changing a wheel, remove any
rust or dirt from places where the wheel attaches
to the vehicle. In an emergency, use a cloth or
a paper towel to do this; but be sure to use a
scraper or wire brush later, if needed, to get all
the rust or dirt off. See Changing a Flat Tire
on
page 6‑83

Storing a Flat or Spare Tire and
Tools
{WARNING:
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 have put the spare tire on your vehicle, store
the flat tire in your trunk.
Store the flat tire as far forward in the trunk as possible.
Store the jack and wheel wrench in their compartment
in the trunk. For storage, the jack must be raised until
the screw end is flush with the edge of the jack.
The compact spare is for temporary use only. Replace
the compact spare tire with a full-size tire as soon as
you can.

Spare Tire
Compact Spare Tire
{WARNING:
Driving with more than one compact spare tire at
a time could result in loss of braking and handling.
This could lead to a crash and you or others could
be injured. Use only one compact spare tire at
a time.
This vehicle may have a compact spare tire. Although
the compact spare tire was fully inflated when the
vehicle was new, it can lose air after a time. Check
the inflation pressure regularly. It should be 60 psi
(420 kPa). After installing the compact spare on the vehicle, stop
as soon as possible and make sure the spare tire is
correctly inflated. The compact spare is made to
perform well at speeds up to 65 mph (105 km/h) for
distances up to 3,000 miles (5 000 km), so you can
finish your trip and have the full-size tire repaired or
replaced at your convenience. Of course, it is best
to replace the spare with a full-size tire as soon as
possible. The spare tire will last longer and be in good
shape in case it is needed again.
Notice:
When the compact spare is installed, do not
take the vehicle through an automatic car wash with
guide rails. The compact spare can get caught on
the rails which can damage the tire, wheel and other
parts of the vehicle.
Do not use the compact spare on other vehicles.
And do not mix the compact spare tire or wheel with
other wheels or tires. They will not fit. Keep the spare
tire and its wheel together.
Notice: Tire chains will not fit the compact spare.
Using them can damage the vehicle and can
damage the chains too. Do not use tire chains on
the compact spare.
