Lexus 2004 GX470, Owner'S Manual

STARTING AND DRIVING
420
Non-genuine Lexus wheels are used.
Although the tires are equipped with air pressure sensors,
the selector switch (see page 425) is set to other tire setting.
CAUTION
The use of non-genuine wheels will cause the air
pressure sensors to transmit the electronic code in
different manner, resulting in the system failure.
The use of different type of tires with genuine wheels
may also cause the malfunction of the system.
CAUTION
When the tire pressure monitoring system warning light
is lit, one or more of your tires is significantly
under-inflated. You should stop and check your tires as
soon as possible, and inflate them to the proper
pressure as indicated on the vehicle’s tire information
placard. Driving on a significantly under-inflated tire
causes the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s handling and
stopping ability. Each tire, including the spare, should
be checked monthly when cold and set to the
recommended inflation pressure as specified in the
vehicle placard and owner’s manual.
