NOTICE
■Be careful when driving over bumps with the spare tire installed on the vehicle.
(GS350/GS200t with compact spare tire, and GS F)
The vehicle may become lower when driving with the spare tire compar ed to when
driving with standard tires. Be careful when driving over uneven road surfaces.
■Driving with tire chains and the spare tire (GS350/GS200t with compact spare tire,
and GS F)
Do not fit tire chains to the spare tire.
Tire chains may damage the vehicle body and adversely affect driving performance.
■When replacing the tires (vehicles with the tire pressure warning system)
When removing or fitting the wheels, tires or the tire pressure warning valve and trans-
mitter, contact any authorized Lexus retailer or Lexus authorized repairer, or any reli-

When trouble arises
GS350_200t_GS F_OM_OM30F83E_(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.
