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.

■

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 (vehicles with the tire

inflation pressure display function)

●

Users of any electrical medical device other than implanted pacemakers and

implanted cardiac 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.

●

People with implanted pacemakers or car-

diac defibrillators should not come within

17.7 in. (450 mm) of the tire pressure warn-

ing system initiators. The radio waves may

affect the operation of such devices.
