When trouble arises
GS450h_300h_OM_OM30F92E_(EE)
Firmly tighten each wheel nut two or
three times in the order shown in the
illustration.
Tightening torque:
103 N•m (10.5 kgf•m, 76 ft•lbf)
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. 555)
■When using the compact spare tire (vehicles with the tire pressure warning system)
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 may become 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 andrear tires of the same size and compact spare tire only)
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.

GS450h_300h_OM_OM30F92E_(EE)
●Stop the vehicle in a safe place on a hard, flat surface.
●Set the parking brake.
●Shift the shift lever to P.
●Stop the hybrid system.
●Turn on the emergency flashers. (P. 452)
●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 any authorized Lexus reta iler or Lexus authorized repairer, or any reli- able repairer.
●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 4 mm (0.16 in.) 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
●When the sealant has expired

When trouble arises
GS450h_300h_OM_OM30F92E_(EE)
Inflate the tire until the recom-
mended pressure is reached.
The sealant will be injected and the
pressure will spike to 300 kPa
(3.0 kgf/cm2 or bar, 44 psi) or
400 kPa (4.0 kgf/cm2 or bar, 58
psi), and then gradually decrease.
The air pressure gauge will dis-
play the actual tire inflation pres-
sure about 1 minute (15 minutes at
low temperature) after the switch
is turned on.
Inject to recommended pressure.
• Turn the compressor switch off
and then check the tire inflation pressure. Being careful not toover inflate, check and repeat the
inflation procedure until the spec- ified tire inflation pressure isreached.
• If the tire inflation pressure is still lowe r than the specified point after inflation for 10 minutes (35 minutes at low temperature) with the switch on, the tire is toodamaged to be repaired. Turn the compressor switch off and contact any
authorized Lexus retailer or Lexus author ized repairer, or any reliable repairer. • If the tire inflation pressure exceeds th e recommended level, let out some air to adjust the tire inflation pressure. ( P. 520, 555)
With the compressor switch off, disconnect the hose from the valve on the tire
and then pull out the power plug from the power outlet socket.
Some sealant may leak wh en the hose is removed.
Install the valve cap onto the valve of the emergency repaired tire.
