*3: When a large child who has outgrown a child restraint system sits in the front passenger seat, the sy stem may recognize him/her as an
adult depending on his/her physique and posture.
*

installed on the front passenger seat when it is unavoidable.

■Front passenger occupant classification system precautions
●If an adult sits in the front passenger se at, the “AIR BAG ON” indicator light is illu-
iminated. 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 forward-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. 9 8 )
●Do not 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 second seat should not contact the front
seatbacks.

■If the vehicle height does not change
If the area around the rear suspension is coated with ice, or the undercarriage has
come into contact with the road surface, the rear height control suspension will not
operate. In this case, the indicator lights will change as follows:
●The current mode indicator light will turn off, and the target mode indicator light
will begin flashing.
●The target mode indicator light will turn off, and the original mode indicator light
will be lit once more. (The vehicle height does not change.)
If the rear height control air suspension cannot be operated even after removing
the ice or progressing to a smooth driving surface, turn off and restart the engine.
■ Parking and stopping tips
●If you immediately stop the engine after of f-road driving, or park the vehicle for
a long time, the vehicle height may gradually lower. When parking, make sure
there is nothing under the vehicle that may come in contact with the underbody.
The vehicle will return to the set height when the engine is started.
●The vehicle height may change as the temperature changes when the engine is
stopped. The vehicle will return to the set height when the engine is started.
■When lowering the vehicle
Even if the engine is stopped while the ve hicle height is being lowered, operation
will continue for up to 25 seconds. If any of the side doors or the back door is
opened within this 25 seconds, operatio n will continue for a further 15 seconds.
■ Rear height control failure warning
●If a malfunction occurs in the rear height control air suspension, normal mode is
automatically selected.
The height control “OFF” indicator will blink, and the vehicle height control can-
not be activated until the malfunction is corrected. Have the vehicle checked at
your Lexus dealer as soon as possible.
●If the height control “OFF” indicator li ght does not come on when the engine
