Use the spare tire temporarily , and only in an emergency.●
Make sure to check the tire inflat ion pressure of the spare tire. (  P. 548)■
When using the spare tire
As the spare tire is not equipped with a tire pressure warning valv e 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 warn ing light comes on, the
light remains on. ■
When the spare tire is equipped
The vehicle becomes lower when driving with the 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 except fo r vehicles with LDH and 19-inch tires)
Install the spare tire on one of the front whee ls of the vehicle. Perform the following steps
and fit tire chains to the rear tires:

502 7-2. Steps to take in an emergency
RC F_UIf you have a flat tire (v ehicles with an emergency
tire puncture repair kit) Your vehicle is not equipped with a spar e 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 emer gency 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 ti re can damage the tire and the wheel beyond
repair. Driving with a flat tire may cause a circumferential groove on the side wall. In
such a case, the tire may explode when using the emergency tire puncture repair kit,
resulting in death or serious injury.

When trouble arises ●
Stop the vehicle in a safe pl ace on a hard, flat surface.●
Set the parking brake. ●
Shift the shift lever to P. ●
Stop the engine. ●
Turn on the emergency flashers. (  P. 442)●
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 vehi cle until the area of the puncture, if
known, is positioned at the top of the tire. ■

Emergency tire puncture repair kit ●
The sealant has a limited lifespan. The expiry date is marked on the bottle. The sealant
should be replaced before the expiry date. Contact your Lexus dealer for replacement.●
The sealant stored in the emergency tire puncture repair kit can be used only once to
temporarily repair a single tire. If the seal ant has been used and needs to be purchased,
contact your Lexus dealer. The compressor is reusable.●
The sealant can be used when the outside temperature is from -40  F (-40  C) to
140  F (60  C).●
The kit is exclusively designed for size and type of tires originally in stalled on your vehi-
cle. Do not use it for tires that a different size than the original ones, or for any other
purposes. ●
If the sealant gets on yo ur clothes, it may stain.●
If the sealant adheres to a wheel or the surface of the vehicle body, the stain may not be
removable if it is not cleaned at once. Immediately wipe away the sealant with a wet
cloth. ●
During operation of the kit, a loud operation noise is produc ed. This does not indicate a
malfunction. ●
Do not use the emergency tire puncture repair kit to check or to adjust the tire pres-
sure.

514 7-2. Steps to take in an emergency
RC F_U WARNING ■
When fixing the flat tire
Observe the following precautions.
Failure to do so may result in death or serious injury.●
Stop your vehicle in a safe and flat area. ●
Do not touch the wheels or the area around the brakes immediately after the vehicle
has been driven.
After the vehicle has been driven, the wheels and the area around the brakes may be
extremely hot. Touching these areas with hands, feet or other body parts may result in
burns. ●
Connect the valve and hose securely with the tire installed on the vehicle.
• If the hose is not properly connected to the valve, air leakage may occur or sealant
may be sprayed out.
• If the hose comes off the valve while inflating the tire, there is a risk that the hose
will move abruptly due to air pressure.
• After inflation of the tire has completed, the sealant may splatter when the hose is
disconnected or some air is let out of the tire. ●
Follow the operation procedure to repair the tire. If the procedure is not followed, the
sealant may spray out. ●
Keep back from the tire while it is being re paired, as there is a chance of it bursting
while the repair operation is being performed. If you notice any cracks or deforma-
tion of the tire, turn off the compressor sw itch and stop the repa ir operation immedi-
ately. ●
The kit may overheat if operated for a long period of time. Do not operate the com-
pressor continuously for more than 35 minutes. ●
Parts of the kit become hot during operation. Be careful handling the kit during and
after operation. Do not touch the metal part around the connecting area between the
bottle and compressor. It will be extremely hot. ●
Do not attach the vehicle speed warning sticker to an area other than the one indi-
cated. If the sticker is attached to an area where an SRS airbag is located, such as the
pad of the steering wheel, it may preven t the SRS airbag from operating properly.■
Driving to spread th e liquid sealant evenly●
Drive the vehicle carefully at a low speed. Be especially careful when turning and cor-
nering. ●
If the vehicle does not drive straight or you feel a pull through the steering wheel, stop
the vehicle and check the following:
• Tire condition. The tire may have separated from the wheel.
• Tire inflation pressure. If tire inflation pressure is 19 psi (130 kPa, 1.3 kgf/cm 2
or
bar) or below, this may in dicate severe tire damage.
