Stowing the flat tire, jack and all tools
Remove the center wheel ornament by pushing from thereverse side.
Lay down the tire with the outer side facing up, and install the
holding bracket.
Then secure the tire, taking care that the tire goes straight up
without catching on any other part, to prevent it from flying for-
ward during a collision or sudden braking.
Keep winding until three clicks are heard.
Stow the tools and jack securely.
■After completing the tire change
The tire pressure warning system must be reset. (P. 495)
■When using the temporary spare tire
As the temporary spare tire is not equipped with the tire pressure warn-
ing valve and transmitter, low inflation pressure of the spare tire will not
be warned. Also, if you replace the temporary spare tire after the tire
pressure warning light comes on, the light remains on.
CAUTION

Improper use of the jack may lead to death or injuries due to the vehicle
suddenly falling off the jack.
●Do not use the jack for any purpose other than replacing tires or install-
ing and removing tire chains.
