4-3. Do-it-yourself maintenance
CAUTION

When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drive train, as well as dan-
gerous 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.

Do not tow if your vehicle has a compact spare tire installed.

When initializing the tire pressure warning system
Do not push the tire pressure warning reset switch without first adjusting the
tire inflation pressure to the specified level. Otherwise, the tire pressure
warning 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.
