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.

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.
