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.

●

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.

• 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.

When trouble 

ari

ses

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.

When replacing an aluminum wheel
with an aluminum wheel, turn the
wheel nuts until the washers come
into contact with the disc wheel.

Lower the vehicle.

Stow the flat tire, tire jack and all tools.

■

The spare tire

●

GS350/GS300: The spare tire is identified by the label “TEMPORARY USE ONLY”

on the tire sidewall.

●

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

●

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

P. 532)

■

When using the spare tire
As the spare tire is not equipped with a tire pressure warning valve and transmitter, low

inflation pressure of the spare tire will not be indicated by the tire pressure warning sys-

tem. Also, if you replace the spare tire after the tire pressure warning light comes on, the

light remains on.

■

When the spare tire is equipped
The vehicle may become lower when driving with the spare tire compared to when driv-

ing 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.

WARNING

■

When using the spare tire

●

Remember that the spare tire provided is specifically designed for use with your vehi-

cle. Do not use your spare tire on another vehicle.

●

Do not use more than one spare tire simultaneously.

●

Replace the spare tire with a standard tire as soon as possible.

●

Avoid sudden acceleration, abrupt steering, sudden braking and shifting operations

that cause sudden engine braking.

WARNING

■

When the spare tire is attached
The vehicle speed may not be correctly detected, and the following systems may not

operate correctly:

Also, not only can the following system not be utilized fully, but it may even negatively

affect the drive-train components:
• AWD  system

■

Speed limit when using the spare tire
Do not drive at speeds in excess of 50 mph (80 km/h) when a spare tire is installed on

the vehicle.
The spare tire is not designed for driving at high speeds. Failure to observe this precau-

tion may lead to an accident causing death or serious injury.

■

After using the tools and jack
Before driving, make sure all the tools and jack are securely in place in their storage

location to reduce the possibility of personal injury during a collision or sudden brak-

ing.

NOTICE

■

Be careful when driving over bumps with the spare tire installed on the vehicle.
The vehicle may become lower when driving with the spare tire compared to when

driving with standard tires. Be careful when driving over uneven road surfaces.

■

Driving with tire chains and the spare tire
Do not fit tire chains to the spare tire.

Tire chains may damage the vehicle body and adversely affect driving performance.

■

When replacing the tires
When removing or fitting the wheels, tires or the tire pressure warning valve and trans-

mitter, contact your Lexus dealer as the tire pressure warning valve and transmitter

may be damaged if not handled correctly.

7-2. Steps to take in an emergency

If you have a flat tire (vehicles without spare tire)

Your vehicle is not equipped with a spare tire, but instead is equipped with an
emergency tire puncture repair kit.
A puncture caused by a nail or screw passing through the tire tread can be
repaired temporarily with the emergency tire puncture repair kit.

WARNING

■

If you have a flat tire
Do not continue driving with a flat tire.

Driving even a short distance with a flat tire can damage the tire and the wheel beyond

repair, which could result in an accident. 

Driving with a flat tire may cause a circumferential groove on the side wall. 

In such a case, the tire may explode when using a repair kit.

When trouble 

ari

ses

●

Stop the vehicle in a safe place on a hard, flat surface.

●

Set the parking brake.

●

Shift the shift lever to P.

●

Stop the engine.

●

Turn on the emergency flashers. (

P. 426)

●

Check the degree of the tire damage.
A tire should only be repaired with
the emergency tire puncture repair
kit if the damage is caused by a nail
or screw passing through the tire
tread.

• Do not remove the nail or screw

from the tire. Removing the
object may widen the opening
and disenable emergency repair
with the kit.

• To avoid sealant leakage, move the vehicle until the area of the puncture, if

known, is positioned at the top of the tire.

■

A flat tire that cannot be repaired with the emergency tire puncture repair kit
In the following cases, the tire cannot be repaired with the emergency tire puncture

repair kit. Contact your Lexus dealer.

●

When the tire is damaged due to driving without sufficient air pressure

●

When the tire lost air pressure due to a crack or damage in the tire sidewall

●

When the tire is visibly separated from the wheel

●

When the cut or damage to the tread is 0.16 in. (4 mm) long or more

●

When the wheel is damaged

●

When two or more tires have been punctured

●

When there is more than one hole or cut in the damaged tire
