CAUTION
■
Tire pressure warning system operation
The tire pressure warning system may not provide warning immediately if a tire
bursts or if sudden air leakage occurs.
■
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.
●
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.
■
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.
