WARNING

■

Replacing a flat tire

●

Do not touch the disc wheels or the area around the brakes immedi-
ately after the vehicle has been driven.
After the vehicle has been driven the disc wheels and the area around
the brakes will be extremely hot. Touching these areas with hands, feet
or other body parts while changing a tire, etc. may result in burns.

●

Failure to follow these precautions could cause the wheel nuts to
loosen and the tire to fall off, resulting in death or serious injury.

• Have the wheel nuts tightened with a torque wrench to 76 ft•lbf (103

N•m, 10.5 kgf•m) as soon as possible after changing wheels.

• Do not attach a heavily damaged wheel ornament, as it may fly off

the wheel while the vehicle is moving.

• When installing a tire, only use wheel nuts that have been specifi-

cally designed for that wheel.

• If there are any cracks or deformations in the bolt screws, nut

threads or bolt holes of the wheel, have the vehicle inspected by
your Toyota dealer.

• When installing the wheel nuts, be sure to install them with the

tapered ends facing inward. (

→P. 546)

●

Observe the following precautions. 
Failure to do so may result in serious injury:

• Do not try to remove the wheel ornament by hand. Take due care in

handling the ornament to avoid unexpected personal injury. 

• Lower the spare tire completely to the ground before removing it

from under the vehicle.

8-2. Steps to take in an emergency

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 spare tire and loosely tighten each wheel nut by hand by
approximately the same amount.



Vehicles with a compact spare tire

Tighten the nuts until the
tapered portion comes into
loose contact with the disc
wheel seat.



Vehicles with a full-size spare tire

Turn the nuts until the washers
come into contact with the
wheel.
