Remove any dirt or foreign mat-
ter from the wheel contact sur-
face.
If foreign matter is on the wheel
contact surface, the wheel nuts
may loosen while the vehicle is in
motion, causing the tire to come
off.
Install the tire and loosely tighten each wheel nut by hand by
approximately the same amount.
Tighten the wheel nuts until the
tapered portion comes into
loose contact with the disc
wheel seat.
Lower the vehicle.
Firmly tighten each wheel nut
two or three times in the order
shown in the illustration.
Tightening torque:
76 ft•lbf (103 N•m, 10.5 kgf•m)
Stow the flat tire, tire jack and all tools.

Use the compact spare tire temporarily, and only in an emergency.
lMake sure to check the tire inflation pressure of the compact spare tire.
( P. 301)
nWhen the compact spare tire is equipped
The vehicle becomes lower when driving with the compact spare tire
compared to when driving with standard tires.
nAfter completing the tire change
The tire pressure warning system must be reset. ( P. 222)
nWhen using the compact spare tire
