CAUTION
■Front passenger occupant classification system precautions
●Do not recline the front passenger seatback so far that it touches the rear seat. This
may cause the “AIR BAG OFF” indicator light to be illuminated, which indicates that
the SRS airbags for the front passenger will no t activate in the event of a severe acci-
dent. If the seatback touches the rear seat, return the seatback to a position where it
does not touch the rear seat. Keep the fron t passenger seatback as upright as possi-
ble when the vehicle is moving. Reclining the seatback excessively may lessen the
effectiveness of the seat belt system.
●If an adult sits in the front passenger seat , the “AIR BAG ON” indicator light is illumi-
nated. 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 correctly. If
the “AIR BAG OFF” indicator still remains illuminated, either ask the passenger to
move to the rear seat, or if that 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 restraint sy stem on the front passenger seat in the
proper order. ( P. 5 7 )
●Do not modify or remove the front seats.
●Do not kick the front passenger seat or subj ect it to severe impact. Otherwise, the
SRS warning light may come on to indicat e a malfunction of the front passenger
occupant classification system. In this ca se, contact your Lexus dealer immediately.
●Child restraint systems installed on the rear seat should not contact the front seat-
backs.
●Do not use a seat accessory, such as a cu shion and seat cover, that covers the seat
cushion surface.
●Do not modify or replace the upholstery of the front seat.

CAUTION
■If a safety system warning light does not come on
Should a safety system light such as th
e ABS/Multi Terrain ABS and the SRS warning

available to help protect you in an accide nt, which could result in death or serious
injury. Have the vehicle inspected by your Lexus dealer immediately if this occurs.

GX460_OM_OM60L72U_(U)4-3. Operating the lights and wipers
■Daytime running light system
●To make your vehicle more visible to other drivers, the parking lights turn on automati-
cally whenever the engine is started and th
e parking brake is released. Daytime running
lights are not designed for use at night.
For the U.S.A.: Daytime running lights can be turned off by operating the switch.
●Compared to turning on the headlights, the daytime running light system offers greater
durability and consumes less electricity, so it can help improve fuel economy.
■Headlight control sensor
■Automatic light off system
●When only the tail lights are on: All lights tu rn off if the engine switch is turned to
ACCESSORY mode or turned off and the driver’s door is opened.
●When the headlights are on: All lights turn off 30 seconds after a door or the glass
hatch is opened and closed.
To turn the lights on again, turn the engine switch to IGNITION ON mode, or turn the
light switch off once and then back to or .
■Automatic headlight leveling system
The level of the headlights is automatically ad justed according to the number of passen-
gers and the loading condition of the vehicle to ensure that the headlights do not inter-
fere with other road users.
■If the automatic headlight leveling system warning light flashes
It may indicate a malfunction in the system. Contact your Lexus dealer.
■Customization
Settings (e.g. light sensor sensitivity) can be changed.
(Customizable features: P. 5 8 6 )
The sensor may not function properly if an
object is placed on the sensor, or anything that
blocks the sensor is affixed to the windshield.
Doing so interferes with the sensor detecting
the level of ambient light and may cause the
automatic headlight system to malfunction.
NOTICE
■To prevent battery discharge
Do not leave the lights on longer than ne
cessary when the engine is not running.

■Conditions in which the function may not operate correctly
In the following conditions, th e camera sensor may be unable to recognize lane markers
causing the lane departure warn ing function to operate incorrectly. However, this does

before a ticket checkpoint
●When driving on a sharp curve
●When lane markers are extremely narrow or extremely wide
●When the vehicle leans to one side an unus ual amount due to a heavy load or improper
tire inflation pressure
●When the following distance between your vehicle and the vehicle ahead is extremely
short
●When the lane markers are yellow (These may be more difficult for the system to rec-
ognize compared to white markers.)
●When the lane markers are broken, “Botts’ dots”, “Raised pavement marker” or stones
●When the lane markers are on a curb etc.
●When lane markers are obscured or partially obscured by sand, dirt, etc.
●When there are shadows on the road running parallel with lane markers, or if a shadow

era lens
●When driving on roads that are branching or merging
●When driving on a road surface that is wet du e to rain, previous rainfall, standing water,

●When the vehicle experiences strong up-and -down motion such as when driving on an
extremely rough road or on a seam in the pavement
●When headlight brightness at nighttime is reduced due to dirt on the lenses, or when
the headlights are misaligned
●When driving on winding roads or roads that are uneven
●When driving on rough or unpaved roads
■When changing the tires
