■When rotating the tires (vehicles with the tire pressure warning system featuring a tire inflation pressure display function)
Make sure that the power switch is off. If the tires are rotated while the power switch is in
ON mode, the tire position information will not be updated. If this accidentally occurs, either turn the power switch to off and then to ON mode, orinitialize the system after checking that the tire pressure is properly adjusted.
■Low profile tires (except 225/50R17 tires)
Generally, low profile tires will wear more rapidly and tire grip performance will be reduced on snowy and/or icy roads when comp ared to standard tires. Be sure to use
snow tires or tire chains on snowy and/or icy roads and drive carefully at a speed appro- priate for road and weather conditions. ( P. 336)
■If the tread on snow tires wears down below 4 mm (0.16 in.)
The effectiveness of the tires as snow tires is lost.
■Situations in which the tire pressure warning system may not operate properly (vehi- cles with the tire pressure warning system)
●In the following cases, the tire pressure warning system may not operate properly.
• If non-genuine Lexus wheels are used. • A tire has been replaced with a tire that is not an OE (Original Equipment) tire.
• A tire has been replaced with a tire that is not of the specified size. • Tire chains etc. are equipped.• An auxiliary-supported run-flat tire is equipped.
• If a window tint that affects the radio wave signals is installed. • If there is a lot of snow or ice on the vehi cle, particularly around the wheels or wheel housings.
• If the tire inflation pressure is extr emely higher than the specified level. • If wheel without the tire pressure warning valve and transmitter are used.
• If the ID code on the tire pressure warning valves and transmitters is not registered in the tire pressure warning computer.
●Performance may be affected in the following situations.
• Near a TV tower, electric power plant, gas station, radio station, large display, air- port or other facility that generates st rong radio waves or electrical noise
• When carrying a portable radio, cellular phone, cordless phone or other wireless communication deviceVehicles with the tire inflation pressure display function: If tire position information is
not correctly displayed due to the radio wave conditions, the display may be corrected by driving and changing the radio wave conditions.
●When the vehicle is parked, the time taken for the warning to start or go off could be
extended.
●When tire inflation pressure declines rapi dly for example when a tire has burst, the warning may not function.
