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 specification. See
Capacities and Specifications
on
page 11‑2for the wheel nut
torque specification.
13. Tighten the wheel nuts firmly in a crisscross sequence, as
shown. 14. Lower the jack all the way and
remove the jack from under the
vehicle.
15. Tighten the wheel nuts firmly with the wheel wrench.
Notice: Wheel covers will not fit
on your vehicle's compact spare.
If you try to put a wheel cover on
the compact spare, the cover or
the spare could be damaged.
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. To store the flat or spare tire and
tools:
1. Place the jack and tools in the
rear storage compartment.
2. Place the flat or spare tire in the storage compartment below the
floor covering.
Secure it with the retainer nut.
If the wheel is larger than the
spare, place the floor cover on
the projecting wheel.
The compact spare is for temporary
use only. Replace the compact
spare tire with a full-size tire as
soon as you can.

9-74 Vehicle Care
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.
If this vehicle has a compact spare
tire it was fully inflated when the
vehicle was new, however, it can
lose air after a time. Check the
inflation pressure regularly. It should
be 420 kPa (60 psi ). 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 105 km/h
(65 mph) for distances up to
5 000 km (3,000 miles), 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. 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.
