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.

●

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.

●

Put the jack properly in its jack point.

●

Do not put any part of your body under the vehicle while it is supported by the jack.

●

Do not start the engine or drive the vehicle while the vehicle is supported by the jack.

●

Do not raise the vehicle while someone is inside.

●

When raising the vehicle, do not put an object on or under the jack.

●

Do not raise the vehicle to a height greater than that required to replace the tire.

●

Use a jack stand if it is necessary to get under the vehicle.

●

Raise the vehicle until the tire is
slightly raised off the ground.

Remove all the wheel nuts and the
tire.

When resting the tire on the ground,

place the tire so that the wheel design

faces up to avoid scratching the wheel

surface.

WARNING

■

Replacing a flat tire

●

Do not touch the disc wheels or the area around the brakes immediately 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.
• Never use oil or grease on the wheel bolts or wheel nuts.

Oil and grease may cause the wheel nuts to be excessively tightened, leading to

bolt or disc wheel damage. In addition, the oil or grease can cause the wheel nuts

to loosen and the wheel may fall off, causing a serious accident. Remove any oil or

grease from the wheel bolts or wheel nuts.

• 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 specifically 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 Lexus dealer.

566

8-2. Steps to take in an emergency

IS350 AWD/IS350/IS300 AWD/IS300_U

Remove any dirt or foreign matter
from the wheel contact surface.

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 approxi-
mately 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.

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.

■

The compact spare tire

●

The compact spare tire is identified by the label “TEMPORARY USE ONLY” on the

tire sidewall.

Use the compact spare tire temporarily, and only in an emergency.

●

Make sure to check the tire inflation pressure of the compact spare tire.

(

P. 595)

■

When using the compact spare tire
As the compact spare tire is not equipped with a tire pressure warning valve and trans-

mitter, low inflation pressure of the spare tire will not be indicated by the tire pressure

warning system. Also, if you replace the compact spare tire after the tire pressure warn-

ing light comes on, the light remains on.

■

When the compact spare tire is equipped
The vehicle becomes lower when driving with the compact spare tire compared to when

driving with standard tires.

■

If you have a flat rear tire on a road covered with snow or ice (vehicles with front and

rear tires of the same size)
Install the compact spare tire on one of the front wheels of the vehicle. Perform the fol-

lowing steps and fit tire chains to the rear tires:

Replace a front tire with the compact spare tire.
Replace the flat rear tire with the tire removed from the front of the vehicle.
Fit tire chains to the rear tires.
