Observe the following precautions. 

Improper use of the tire jack may cause the vehicle to suddenly fall off

the jack, leading to death or serious injury.

●

Only use the tire jack that comes with this vehicle for replacing a tire. 

Do  not  use  it  on  other  vehicles,  and  do  not  use  other  tire  jacks  for

WARNING

■

Replacing a 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.

• 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 the wheel nuts with

the tapered ends facing inward. (
