CAUTION
■Front passenger occupant classification system precautions
●If an adult sits in the front passenger se at, the “AIR BAG ON” indicator light is illu-
minated. If the “AIR BAG OFF” indicator is illuminated, ask the passenger to sit
up straight, well back in the seat, feet on the floor, and with the seat belt worn cor-
rectly. If the “AIR BAG OFF” indicator still remain illuminated, either ask the pas-
senger to move to the rear seat, or if th at is not possible, move the front passenger
seat fully rearward.
●When it is unavoidable to install a forw ard-facing child restraint system on the
front passenger seat, install the child rest raint system on the front passenger seat
in the proper order. ( P. 1 0 2 )
●Do not modify or remove the front seat.
●Do not kick the front passenger seat or subject it to severe impact. Otherwise,
the SRS warning light may come on to indicate a malfunction in the detection sys-
tem. In this case, contact your Lexus dealer immediately.
●Do not use a seat accessory, such as a cushion or seat cover, that covers the seat
cushion surface.
●Child restraint systems installed on the rear seat should not contact the front seat-
backs.

CAUTION
■If a safety system warning light does not come on
Should a safety system light such as ABS and the SRS airbag warning light not
come on when you turn to IGNITION ON mode, this could mean that these sys-
tems 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 the indicated
vehicle’s systems. ( P. 4 8 8 )
*: 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 on, or after a few seconds.
There may be a malfunction in a system if the lights do not come on, or
turn off. Have the vehicle inspected by your Lexus dealer.
