Tire Pressure Warning System Reset Switch - Lexus 2004 LS430 Owner's Manual

CAUTION
When the tire pressure warning message appears,
observe the following instructions:
D Adjust the tire inflation pressure to the specified level
as soon as possible.
D Avoid abrupt steering wheel maneuvering and
braking. If the vehicle tires are deteriorated, you
could lose control of the steering wheel or the brakes,
causing death or serious injury.
Note: The tire pressure warning system on your
vehicle will warn you when one of your tires is
significantly under-inflated and
combinations of your tires are
under-inflated. However, there are other combinations
of significantly under-inflated tires for which your tire
pressure warning system may not warn you. These
other combinations are relatively common, accounting
for approximately half the instances in which vehicles
have significantly under-inflated tires. For example,
your system may not warn you when both tires on the
same side or on the same axle of your vehicle are
significantly under-inflated. It is particularly important,
therefore, for you to check the tire inflation pressure in
all of your tires regularly and maintain proper pressure.

after tires or wheels are replaced or rotated.
To initialize the system, perform the following:
1. Park the vehicle at a safe place with the parking brake
