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 winter tires.
●
Using tires of a different size
■
Do not use tires of a different size from those equipped when the vehicle was new,
as the front tire steering angle setting is designed for the original tire size. It is dan-
gerous to use an incorrect wheel and tire combination as this may result in reduced
vehicle stability.
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.
