NOTICE

Repairing or replacing tires, wheels, tire pressure warning valves, transmitters
and tire valve caps (vehicles with the tire pressure warning system)

When removing or fitting the wheels, tires or the tire pressure warning valves
and transmitters, contact any authorized Lexus dealer or repairer, or another
duly qualified and equipped professional as the tire pressure warning valves
and transmitters may be damaged if not handled correctly.

Make sure to install the tire valve caps. If the tire valve caps are not installed,
water could enter the tire pressure warning valves and the tire pressure warn-
ing valves could be bound.

When replacing tire valve caps, do not use tire valve caps other than those
specified. The cap may become stuck.

To avoid damage to the tire pressure warning valves and transmitters (vehicles
with the tire pressure warning system)
When a tire is repaired with liquid sealants, the tire pressure warning valve and
transmitter may not operate properly. If a liquid sealant is used, contact any
authorized Lexus dealer or repairer, or another duly qualified and equipped
professional or other qualified service shop as soon as possible. Make sure to
replace the tire pressure warning valve and transmitter when replacing the tire.


Driving on rough roads
Take particular care when driving on roads with loose surfaces or potholes.
These conditions may cause losses in tire inflation pressure, reducing the cush-
ioning ability of the tires. In addition, driving on rough roads may cause dam-
age to the tires themselves, as well as the vehicle’s wheels and body.

Low profile tires (except 16-inch tires)
Low profile tires may cause greater damage than usual to the tire wheel when
sustaining impact from the road surface. Therefore, pay attention to the follow-
ing:

Be sure to use proper tire inflation pressure. If tires are under-inflated, they
may be damaged more severely.

Avoid potholes, uneven pavement, curbs and other road hazards. Failure to do
so may lead to severe tire and wheel damage.

If tire inflation pressure of each tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.
