I have the optional Bi-xenon headlights with PDLS, according to the description, there are auxiliary headlamps and fog lights, but how do you turn these on?

 

I use auto lights, but if I remember correctly turn the light switch right and pull to get fogs on.

 

That is to turn on the rear fog lights. So the Panamera has no front fog lights? Unlike the Cayenne?

 

According to the technical specs, if you get the optional Bi-Xenon lights, they include fog lights in the front. The rear light is separate. It sounds like when you activate the rear fog light, the front lights 'fan out' and act as fog lights. Here's the description from the Porsche website:

All models are equipped with a driving light assistant, which switches the lights on automatically when it gets dark. As standard, the Panamera, Panamera 4 and Panamera Diesel feature halogen headlights with manual range adjustment – all other models are equipped with Bi-Xenon headlights with dynamic range adjustment and a headlight cleaning system. With dipped or main beam, the road ahead is illuminated more uniformly. The lighting system features an automatic switch-off and the ‘Welcome Home’ function – a customisable delayed switchoff timer that keeps the daytime running lights, the taillights and, where applicable, the courtesy lights (p. 81) switched on until you reach your front door.

LED daytime running lights are standard equipment on all Panamera models. On the Panamera Turbo models, each main headlight unit has four LED spotlights; on all other models, the LEDs are arranged horizontally in the front light units. Daytime running lights improve safety driving daylight hours as they make you more visible to other road users.

Also contained in the front light units are the direction indicators, bar-shaped LED light guides in the form of position lights or – exclusively reserved for the Panamera Turbo models – LED light guides as a border for the indicators.

The Porsche Dynamic Light System (PDLS) is standard on the Panamera Turbo models and available as an option for all other Panamera models. Its dynamic cornering light function swivels the headlights towards the inside of a bend based on steering angle and road speed and the static cornering lights activate the auxiliary headlights in order to illuminate more of the road at tight bends and turns. Put simply, when you enter a bend, the road ahead is illuminated immediately so you can see any obstacles much sooner.

The system also features speeddependent headlight range control. With adaptive light systems, it is possible for the maximum range of the dipped beams to be increased as a function of the speed of the vehicle. PDLS takes care of this automatically. When driving at higher speeds, such as on the motorway, the range of the dipped beams is adjusted by adapting the shape of the light cone, extending it further forward to improve visibility without dazzling oncoming traffic.

Another feature of the PDLS, the adverse weather function, is activated when you switch on the rear fog light. It reduces the effect of reflection phenomena in poor visibility conditions, e.g. fog, heavy rain or snowfall. The dipped beams are fanned out and the light cone is lowered to reduce the risk of the driver being dazzled.

In the event of sudden braking, the adaptive LED brake lights on all Panamera models pulsate to alert following traffic more quickly to a critical situation.

Vehicles with the driver memory package or 14-way power seats with memory package (standard in the Panamera Turbo models) feature LED courtesy lights in the exterior mirrors to illuminate the area around the doors.

LED technology is also used for the taillights, the additional brake light in the rear lid, the rear direction indicators and the rear fog light. LEDs provide better illumination and respond more quickly to driver input. For greater safety – and an unmistakable Porsche design, day or night.

 

Bi-Xenon Lighting System incl. Porsche Dynamic Light System (PDLS)

Bi-Xenon headlights with dynamic range control, headlight cleaning system, H7 Auxiliary main-beam headlights, LED daytime running lights, static and dynamic cornering lights, speed-dependent headlight range control including fog lights.

What about the H7 Auxiliary main-beam headlights?

 

Main beam= high beam, you push or pull the stalk

 

Thanks for the clarification. The high beam looks like they are just halogen, as the light beam looks more yellow than the xenon low beam. My understanding is that bi-xenon means both high and low beam are xenon?

 

It should mean that, so I think the H7s are assisting the Xenon high beams.

 

So that's why Porsche is referring them as "auxiliary" main beam headlights.

 

This is good info to know!

 

Since this is the only headlamp you need to change here goes the how to do it:
