counterclockwise, then pull it
straight out.
WARNING:Handle a halogen headlamp bulb carefully and keep
out of children’s reach. Grasp the bulb only by its plastic base
and do not touch the glass. The oil from your hand could cause the
bulb to break the next time the headlamps are operated.

tightening the screws in a criss-cross pattern (upper-left, lower right
etc.)

out, the bulb and starter capsule assembly must be replaced by your
authorized dealer.
