running light, on the same side, is turned
off. For emergency flashers, both are
turned off.
■Headlight control sensor
The sensor may not function properly if an
object is placed on th e sensor, or anything
that blocks the sensor is affixed to the wind-
shield.
Doing so interferes with the sensor detect-

of the headlights according to vehicle
speed and the degree of the tire’s angle
as controlled by steering input.
AFS operates at speeds of 6 mph (10 km/
h) or higher.
