H7 Headlights

The clear glass look gives an unrestricted view of the new technologies
that are used here. The Cayenne and Cayenne S come with H7
projector-type headlights as standard. The light from the light source is
projected onto the road via a reflector and a lens and thus allows homo-
geneous illumination with significantly less dazzling of oncoming traffic.
The H7 projection system offers the following advantages for
dipped beam headlights:
• High luminous flux.
• More defined light/dark limit resulting in less dazzle for other road
users.
• Homogeneous illumination of the entire road.

Bi-Xenon Headlights

The dynamic cornering light is new for Bi-Xenon headlights (standard for
Cayenne Turbo, optional for Cayenne and Cayenne S). In addition to the
existing static cornering light, which is particularly useful when turning,
the dynamic cornering light provides better illumination of corners on
the road, e.g. when driving cross country. Neither the static nor the
dynamic cornering light is active when driving straight ahead. A sharp
turn of the steering wheel activates the static cornering light while
driving (up to max. 80 mph (130 km/h) ) and when the vehicle is
stationary.
