CAUTION
■If a safety system warning light does not come on
Should a safety system light such as the ABS and SRS warning light not come on
when you start the engine, this could mean that these systems are not available to
help protect you in an accident, which could result in death or serious injury. Have
the vehicle inspected by your Lexus dealer immediately if this occurs.
■ Warning lights
Warning lights inform the driver of malfunctions in any of the vehi-
cle’s systems. ( P. 463)
*: These lights turn on when the “ENGINE START STOP” switch is turned
to IGNITION ON mode to indicate that a system check is being per-
formed. They will turn off after the en gine is started, or after a few sec-
onds. There may be a malfunction in a system if a light does not come
on, or if the lights do not turn off. Have the vehicle inspected by your
Lexus dealer.
