CAUTION

When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drivetrain as well as danger-
ous handling characteristics, which may lead to an accident resulting in death
or serious injury.

Do not mix tires of different makes, models or tread patterns.
Also, do not mix tires of remarkably different treadwear.

Do not use tire sizes other than those recommended by Lexus.

Do not mix differently constructed tires (radial, bias-belted or bias-ply tires).

Do not mix summer, all season and snow tires.

Do not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously.

Vehicles with a compact spare tire: Do not tow if your vehicle has a compact
spare tire installed.

Vehicles with an emergency tire puncture repair kit: Do not tow anything if a
tire that has been repaired using the emergency tire puncture repair kit is
installed. The load on the tire may cause unexpected damage to the tire.

When initializing the tire pressure warning system (vehicles with the tire pres-
sure warning system)
Do not operate the tire pressure warning reset switch without first adjusting the
tire inflation pressure to the specified level. Otherwise, the tire pressure warn-
ing light may not come on even if the tire inflation pressure is low, or it may
come on when the tire inflation pressure is actually normal.
