CAUTION
■Replacing a flat tire
●Do not touch the disc wheels or the area around the brakes immediately after the
vehicle 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 da mage. 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 or grease from the wheel bolts or wheel nuts.
• Have the wheel nuts tightened with a torque wrench to 76 ft•lbf (103 N•m, 10.5 kgf•m) 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 holes of the wheel, have the vehicle inspected by your Lexus dealer.

5107-2. Steps to take in an emergency
GS350_OM_OM30F69U_(U)Remove any dirt or foreign mat-
ter from the wheel contact sur-
face.
If foreign matter is on the wheel con-
tact surface, the wheel nuts may
loosen while the vehicle is in motion,
causing the tire to come off.
Install the spare tire and loosely
tighten each wheel nut by hand by
approximately the same amount.
When replacing an aluminum
wheel with a steel wheel, tighten
the wheel nuts until the tapered
portion comes into loose contact
with the disc wheel seat.

wheel with an aluminum wheel,
turn the wheel nuts until the
washers come into contact with

■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.

pressure warning system. Also, if you replace the compact spare tire after the tire
pressure warning light comes on, the light remains on.

when driving with standard tires.

and rear tires of the same size)

following steps and fit tire chains to the rear tires:
Replace a front tire with the compact spare tire.
