■Daytime running light system (if equipped)
●Bulb type: To make your vehicle more visible to other drivers during daytime
driving,  the  daytime  running  lights  turn  on  automatically  whenever  the
engine is started and the parking brake is released with the headlight switch
off  or  in  the  “AUTO”  position.  (illuminate  dimmer  than  the  headlights)  Day-
time running lights are not designed for use at night. 
For  the  U.S.A.:  Daytime  running  lights  can  be  turned  off  by  operating  the
headlight switch.
LED type: To make your vehicle more visible to other drivers during daytime
driving,  the  daytime  running  lights  turn  on  automatically  whenever  the
engine  is  started  and  the  parking  brake  is  released  with  the  headlight
switch off. 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
headlight 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
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  sys-
tem to malfunction.
