■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.  5 5 0 )
■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 treadwear indicato rs appear on the tire, replace the tire. ( P.  4 2 1 )
■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 warned. 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 temporary emer-
gency use only.
