■The compact spare tire
●The compact spare tire is identified by the label “TEMPORARY USE ONLY”
on the tire sidewall.
Use the compact spare tire temporarily only in an emergency.
●Make sure to check the tire inflatio n pressure of the compact spare tire. 
(  P. 4 8 7 )
■Tr e a d l i f e
The compact spare tire can be used many times, if necessary. It has tread life of up
to

3000 miles (4800 km) depending on road conditions and your driving habits.
When tread wear indicators appear on the tire, replace the tire. ( P. 3 7 5 )
■When using the compact spare tire
As the spare tire is not equipped with the tire pressure warning valve and transmit -
ter, low inflation pressure of the spare tire will not be w
arned. Also, if you replace the
compact spare tire after the tire pressure warning light comes on, the light remains
on.
■ Compact spare tire
The compact tire saves space in your luggage compartment, and its
lighter weight helps to enhance fuel economy and permits easier
installation in case of a flat tire.
The compact spare tire is
designed for tempor
ary emer-
gency use only.
