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 high beams may be turned off if a
vehicle ahead that is using fog lights with- out its headlights turned on is detected.
●House lights, street lig
hts, traffic signals,
and illuminated billboards or signs and
other reflective objects may cause the
high beams to change to the low beams,
or the low beams to remain on.
●The following factors may affect the
amount of time taken for the high beams
to turn on or off:
• The brightness of the headlights, fog
lights, and tail lights of vehicles ahead
• The movement and direction of vehicles ahead
• When a vehicle ahead only has opera- tional lights on one side

●The high beams may turn on or off unex-
pectedly.
●Bicycles or similar vehicles may not be
detected.
●In the following situations the system may
not be able to correctly detect the sur-
rounding brightness level. This may cause
the low beams to remain on or the high
beams to flash or dazzle pedestrians or
vehicles ahead. In such a case, it is neces-
sary to manually swit ch between the high
and low beams.
