■Daytime running light system
●The daytime running lights illuminate using th
e same lights as the parking lights and illu-
minate brighter than the parking lights.
●To make your vehicle more visible to other drivers during daytime driving, the daytime
running lights turn on automatically when a ll of the following conditions are met. (The
daytime running lights are not designed for use at night.)
• The engine is running
• The parking brake is released

*: When the surroundings are bright
The daytime running lights remain on after they illuminate, even if the parking brake is
set again.
●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.

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.

WARNING
■Lexus Safety System +
The Lexus Safety System + is designed to operate under the assumption that the driver
will drive safely, and is designed to help reduce the impact to the occupants and the
vehicle in the case of a collision or assist the driver in normal driving conditions.
As there is a limit to the degree of reco gnition accuracy and control performance that
this system can provide, do not overly rely on this system. The driver is always responsi-
ble for paying attention to the vehicle’s surroundings and driving safely.
