Electrics/Electronics Light Systems Main Headlights Panamera/4/S/4S Panamera Turbo Panamera/4/S/S4 Low beam/driving light Depending on the light switch position, the low beams are switched on automatically in the following situations: dusk, darkness, driving through tunnels, rain, highway driving Highway function in bright conditions The driving light is switched on automatically at speeds of more than approx. 90 mph (140 km/h) in bright conditions and when the daytime running lights are deactivated. When driving at a speed of less than approx. 40 mph (65 km/h), the driving light is switched off after a delay of approx. 4 minutes if the external lighting conditions permit. Rain function The driving light is switched on automatically after five seconds of continuous wiper operation. If the wipers have not been used for approx. 4 minutes, the driving light is switched off. Fog lights When the fog lights are switched on, the driving light distribution changes at speeds of less than approx. 38 mph (60 km/h). The light beam is widened and glare is reduced.

On the Panamera/4 and Panamera S/4S, the front lights also house the horizontal, LED-technology day- time driving lights. On the Panamera Turbo, the daytime driving lights – with four LED spotlights each – are located as mentioned earlier in the main headlights. The position light (LED light guides) is designed to surround the direction indicator lights. Daytime running lights increase driving safety during the day by making the vehicle more visible for other road users.

The headlight adjustment angles depend on the vehicle speed and how sharply the driver turns the steering wheel. Viewed from the center axis of the vehicle, the maximum adjustment angle of the headlight at the inside of the bend is 15º, while the headlight angle at the outside of the bend is 7.5º. This ensures the widest possible illumination of the bend because the two light beams do not focus their light on a single point. The low beam in the Bi-Xenon headlights follows the driver’s The AFS consists of a swivelling AFS VarioX module for the steering movements and continuously adjusts to the dynamic cornering light and headlight levelling and works current driving speed. Sensors continuously record the in accordance with the projection system. The projection driving speed, lateral acceleration and steering angle, and system includes, among other components, a rotating use this information to “measure” the corner. A control unit drum with various contours for modifying the light/dark uses the data it receives to work out the best angle border of the light as, well as a lens. for controlling the dynamic cornering light. The Bi-Xenon headlight can be set to different light modes, The cornering light also remains active when the high e.g. country road light and highway light, by way of the beam is switched on, improving the driver’s visibility.

The static cornering light is activated by the direction indicators or by turning the steering wheel when the vehicle is stationary and while driving at low speeds of up to 25 mph (40 km/h). Only the movement of the steering wheel activates the static cornering light at higher speeds.

Headlight range control reduces reflections in low-visibility conditions, e.g. in fog changes the range of the dipped beam at higher speeds or when driving on snow. The dipped beam spreads out by adapting the light beam. The light spreads further wider and the left headlight adapts the light/dark border forward and thus improves visibility without blinding horizontally, thereby reducing the range of the light beam. oncoming traffic. The left headlight also swivels to the left, causing the focal point of the light to move outwards accordingly. This reduces dazzle for the driver. The fog light function is available at speeds of up to 45 mph (70 km/h). The light system switches back to country road light at higher speeds. light Highway Light The light intensity is increased in conjunction with more effective adaptation at the light/dark border. The highway light is activated at speeds of over 80 mph (130 km/h) in the absence of other factors (the light beam becomes longer). The highway light also comes on when the vehicle is travelling at a speed of more than 70 mph (110 km/h) for a long stretch (70 seconds) with a small steering angle (i.e. radius of bend greater than 500 m). The highway light is characterized by higher light intensity and a more effective adaptation of the light/dark border for these speeds. The highway light is deactivated at speeds of less than 56 mph (90 km/h), depending on the time delay and the steering angle (radius of bend). The highway light is switched off immediately without any other conditions at speeds of less than 45 mph (70 km/h). It is important to bear in mind here that the highway light will not be activated in markets with speed limits of less than 110 km/h or 70 mph (e.g. parts of USA)! Page 9.62 General Servicing & Repair - Panamera Electrics/Electronics Light Functions This illustration gives a summary of how the light functions high beam, country road light, highway light and fog light function can be produced using the various contours of the drum in headlights with the adaptive light system. The Xenon headlight shines onto the drum and projects the contour of the drum onto the lens (projection system). This produces the blended con- tours and light/dark borders on the road surface.
