ªACCº or ªLOCKº position. To turn them on again, turn
the ignition key to the ªONº position, or turn the headlight
switch off

make sure the headlight switch is off. Daytime Running Light System
The headlights turn on at reduced intensity when the
parking brake is released with the engine started, even
