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 start the hybrid system, this could mean that these systems are
not available to help protect you in an accident, which could result in death or seri-
ous 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.
*: These lights turn on when the engine switch is turned to the ON position
to indicate that a system check is being performed. They will turn off
after the hybrid system is started, or after a few seconds. 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.

AFS (vehicles with discharge headlights)AFS (Adaptive Front Lighting System) improves visibility at intersections
and on curves by automatically adjusting the direction light axis of the
headlights according to vehicle speed and the degree of the tire angle
that are controlled by steering input.
Operates at speeds of 18 mph (30 km/h) or higher.
■ Deactivating AFS
Turn the switch OFF to deactivate
AFS.
OFF
ON
■Daytime running light system
To make your vehicle more visible to other drivers, the headlights turn on automati-
cally (at a reduced intensity) whenever the hybrid system is started and the parking
brake is released. Daytime running lights are not designed for use at night.
■Headlight control sensor
The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the wind-
shield.
Doing so interferes with the sensor detecting
the level of ambient light and may cause the
automatic headlight control system to mal-
function.

●When only the tail lights come on: The tail lights turn off automatically with the
engine switch turned to the ACC or LOCK position and the driver’s door is
opened.
To turn the lights on again, turn the engine switch to the ON position, or turn the
light switch OFF once and then back to the
or position.
■Automatic headlight leveling system (vehicles with discharge headlights)
The level of the headlights is automatically adjusted according to the number of
passengers and the loading condition of the vehicle to ensure that the headlights do
not interfere with other road users.
■If the indicator flashes... (veh icles with discharge headlights)
It may indicate a malfunction in the system. Contact your Lexus dealer.
■Customization that can be configured at Lexus dealer
Setting (e.g. light sensor sensitivity) can be changed. (Customizable features
→ P. 4 5 8 )
