Headlamp: Description and Operation
Lighting System
Headlamps (H7)
New headlamps were developed specially for the Cayenne series. The standard headlamps used for the Cayenne S consist of an H7 low beam with manual leveling and an H7 reflecting high beam with an H7 auxiliary driving lamp. As with the 911 Carrera and Boxster, the headlamp is integrated into a single housing.
The front parking light and turn signal are likewise housed in the headlamp unit. The headlamp unit is a plug-in module. It is simple to access and allows easy replacement of the bulbs.
The side turn signals in the front fenders are white in color.
Headlamp Washer System
A headlamp washer system is available for the Cayenne either as a separate option or as part of the "Advanced Of{Road Package. This is designed as a piston system; each headlamp is cleaned with two water nozzles.
Bi-Xenon headlamps with dynamically-controlled cornering light (ID-Number for Cayenne S)
This headlamp is standard equipment in the Cayenne Turbo. The dynamically controlled cornering light is a new feature of this lighting system. The Bi-Xenon headlamp is equipped with automatic-dynamic leveling as well as a headlamp washer system as standard equipment.
Each headlamp contains a supplementary H3 low beam light. The position of the supplementary light provides significantly improved illumination to the left and right of the primary light beams.
A control module to determine the lighting dynamics of the left and right headlamps processes steering angle and vehicle speed. The optimal relationship between sensor values and lighting dynamics was determined through testing and has been stored as a data transmission function in the control module.
In addition to providing improved driving comfort, this system also increases driving safety. When driving off-road, this technology is highly useful in early detect on of obstacles to the side.
The following describes the relationships between the dynamically controlled corner mg light and other illumination functions.
- The cornering light always functions together with the low beam.
- If the low beam fails in one headlamp, then the corresponding cornering light shuts off to avoid asymmetrical illumination.
- When high beams are used, the cornering lights operate at their lowest illumination. operating the headlight flasher does not affect the cornering light function.
Front Fog Lamps with Rear Fog Lamps
The fog lamps (Hi 1) are located in the front nose section of the cayenne.
Both the front and rear fog lamps are switched on and off by the light switch.
The parking light must be switched on before the fog lamps will operate.
The low beam may also be operated together with the fog lamps.
Each tail light unit houses the rear fog lamps. The rear fog lamps may only tie switched on if the both the parking light and front tog lamps are operating. The low beam may also be used.
Tail Light Units
The tail lights of the Cayenne are a single unit integrated into the tail of the vehicle. The tail light unit has a layered effect in a single housing.
- Turn signal
- Rear fog lamps
- Back-up light
- Brake light
- Parking light
- Reflector
A clear glass section covers the lights, which create distinctly contoured bands when illuminated.
The third brake light has LEDs and is integrated into the rear spoiler.
