CAUTION
When inspecting or replacing tires
■
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drivetrain as well as dangerous han-
dling 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 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 pacemakers,
●
cardiac resynchronization therapy-pacemak-
ers or implantable cardioverter defibrillators
should not come within 17.7 in. (450 mm) of
the tire pressure warning system initiators.
The radio waves may affect the operation of
such devices.
Users of any electrical medical device other than implantable cardiac pacemakers,
●
cardiac resynchronization therapy-pacemakers or implantable cardioverter defibril-
lators should consult the manufacturer of the device for information about its opera-
tion under the influence of radio waves.
Radio waves could have unexpected effects on the operation of such medical
devices.
