GS350_GS F_OM_OM30J07U_(U)
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 spare tire
●GS350: 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 inflat ion pressure of the spare tire. (P. 525)
■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.

When trouble arises
■Emergency tire puncture repair kit
●The sealant has a limited lifespan. The expiry date is shown 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 sealant has been used and need to be purchased,
contact your Lexus dealer.
●The sealant can be used when the outside temperature is from -40 F (-40 C) to
140 F (60 C).
●The repair kit is exclusively designed for size and type of tires originally installed on your
vehicle. Do not use it for tires that a differen t 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 repair kit, a loud operation noise is produced. This does not
indicate a malfunction.
●Do not use the emergency tire puncture repair kit to check or to adjust the tire pres-
sure.
■If the tire is inflated to mo re than the recommended level
Disconnect the hose from the valve.
Disconnect the hose from the valve, remove the air releas e cap from the hose and then
reconnect the hose.
Turn the compressor switch on and wait for several seconds, and then turn it off. Check
that the air pressure indicator shows the recommended level. ( P. 525)
If the air pressure is lower than the reco mmended level, turn the compressor switch on
again and repeat the inflation procedure un til the recommended pressure is reached.
■The valve of a tire that has been repaired
●After a tire is repaired with the emergency tire puncture repair kit, the valve should be
replaced.
●After a tire is repaired with the emergency tire puncture repair kit, even if the tire infla-
tion pressure is at the recommended level, the tire pressure warning light may come
on/flash.
■Note for checking the emergency tire puncture repair kit
Check the sealant expi ry date occasionally.
The expiry date is shown on the bottle.
Do not use sealant whose expiry date has al ready passed. Otherwise, repairs conducted
using the emergency tire puncture repa ir kit may not be performed properly.
Install the air release cap to the end of the
hose and push the protrusion on the air
release cap into the tire valve to let some air
out.

WARNING
■Caution while driving
Observe the following precautions.
Failure to do so may cause an accident.
●The emergency tire puncture repair kit is made exclusively for your vehicle. Do not
use it on other vehicles.
●Do not use the emergency tire puncture repair kit for tires that are a different size
than the specified ones or for any other pu rpose. Doing so may cause the tires to not
be repaired properly.
■Precautions for use of the sealant
●Ingesting the sealant is hazardous to your health. If you ingest sealant, consume as
much water as possible, and then immediately consult a doctor.
●If sealant gets in eyes or adheres to skin, immediately wash it off with water. If discom-
fort persists, consult a doctor.
■When fixing the flat tire
●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 dis-
connected or some air is let out of the tire.
●Follow the operation procedure to repair the tire. If the procedures 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 switch and stop the repa ir operation immedi-
ately.
●The repair kit may over heat if operated for a long peri od of time. Do not operate the
repair kit continuously for more than 35 minutes.
●Parts of the repair kit become hot during oper ation. Be careful handling the repair kit
during and after operation. Do not touch the metal part connecting the bottle and the
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 prevent the SRS air bag from operating properly.
