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 seri-
ous 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.
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 operate 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.
Caution regarding interference with electronic devices
■
People with implantable cardiac pacemak-
●
ers, cardiac resynchronization therapy-
pacemakers or implantable cardioverter
defibrillators should not come within 17.7 in.
(450 mm) of the tire pressure warning sys-
tem initiators. The radio waves may affect
the operation of such devices.
Users of any electrical medical device other than implantable cardiac pacemak-
●
ers, cardiac resynchronization therapy-pacemakers or implantable cardioverter
defibrillators should consult the manufacturer of the device for information about
its operation under the influence of radio waves.
Radio waves could have unexpected effects on the operation of such medical
devices.
