WARNING
■Replacing a flat tire
●Do not touch the disc wheels or the area around the brakes immediately after thevehicle 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 orgrease from the wheel bolts or wheel nuts.
• Have the wheel nuts tightened with a torque wrench to 103 N•m (10.5 kgf•m, 76 ft•lbf) 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 holesof the wheel, have the vehicle inspected by any authorized Lexus retailer or Lexus
authorized repairer, or any reliable repairer.

surface, the wheel nuts may loosen while the vehicle is in motion, causingthe tire to come off.
Install the tire and loosely tighten each wheel nut by hand by approximately
the same amount.
When replacing an aluminum wheel

When trouble arises
GS450h_300h_OM_OM30F92E_(EE)
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 ci rcumferential groove on the side wall. In such a case, the tire may explode when using a repair kit.

5107-2. Steps to take in an emergency
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
