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 dangerous
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.
●
When initializing the tire pressure warning system
■
Do not press the satellite 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.
