WARNING
■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 acc ident 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 th an 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.
●Vehicles with a compact spare tire: Do not tow if your vehicle has a compact spare
tire installed.
●Vehicles with an emergency tire puncture repa ir kit: Do not tow anything if a tire that has been repaired using the emergency tire puncture repair kit is installed. The load
on the tire may cause unexpected damage to the tire.
■When initializing the tire pressure warning system
Do not operate the tire pressure warning re set switch without first adjusting the tire
inflation pressure to the specified level. Ot herwise, the tire pressure warning light may not come on even if the tire inflation pressu re is low, or it may come on when the tire inflation pressure is actually normal.
■Caution regarding interference with electronic devices (vehicles with the tire pres-sure warning system featuring a tire inflation pressure display function)
●Users of any electrical medical device other than implantable cardiac pacemakers,cardiac resynchronization therapy-pacemakers or implantable cardioverterdefibrillators 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 medicaldevices.
●People with implantable cardiac pacemakers,cardiac resynchronization therapy-pacemak-ers or implantable cardioverter defibrillators
should not come within 450 mm (17.7 in.) of the tire pressure warning system initiators.The radio waves may affect the operation of
such devices.
