When trouble arises
The warning lights and warning buzzers operate as follows depending on the con-
tent of the message. If a message indicates the need for inspection by a dealer,
have the vehicle inspected by your Lexus dealer immediately.
TPMS (tire pressure warning system)
malfunctions may occur for a variety of
reasons, including the installation of
replacement or alternate tires or wheels
on the vehicle that prevent the TPMS
(tire pressure warning system) from
functioning properly. Always check the
TPMS (tire pressure warning system)
malfunction telltale after replacing one
or more tires or wheels on your vehicle
to ensure that the replacement or alter-
nate tires and wheels allow the TPMS
(tire pressure warning system) to con-
tinue to function properly.
■ To ensure the tire pressure warning
system operates properly
Do not install tires with different specifi-
cations or manufacturers, as the tire
pressure warning system may not oper-
ate properly.
If a warning message is dis-
played
The multi-information display
shows warnings of system malfunc-
tions, incorrectly performed opera-
tions, and messages that indicate a
need for maintenance. When a
message is shown, perform the cor-
rection procedure appropriate to
the message.
If a warning message is displayed
again after the appropriate actions
have been performed, contact your
Lexus dealer.
