the jack, leading to death or serious injury.

●

Do not use the tire jack for any purpose other than replacing tires or

installing and removing tire chains.

●

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

tire. 

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

replacing tires on this vehicle.

WARNING

■

Replacing a flat tire

●

Observe the following precautions. 

Failure to do so may result in serious injury:
• Lower  the  spare  tire  completely  to  the  ground  before  removing  it

from under the vehicle.

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

handling the ornament to avoid unexpected personal injury.

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

the wheel while the vehicle is moving.

• 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 83 ft•lbf (112

N•m, 11.4 kgf•m) steel wheels, 76 ft•lbf (103 N•m, 10.5 kgf•m) alumi-

num wheels, 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  them  with  the

tapered ends facing inward. (

7-2. Steps to take in an emergency

4RUNNER (U)

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.
When  replacing  an  aluminum
wheel  with  a  steel  wheel,
tighten the wheel nuts until the
tapered  portion  comes  into
loose  contact  with  the  disc
wheel seat.

When  replacing  an  aluminum
wheel with an aluminum wheel,
tighten the wheel nuts until the
washers  comes  into  contact
with the disc wheel.
