Lighting and Horns: Description and Operation

96 Interior Lights

The interior lighting in the 911 Carrera is based closely on the concept used in the previous model. New are the white LEDs for instruments and controls, which offer better illuminating power than the yellow LEDs used in the previous model. This has improved the readability of the instruments, particularly at dawn and dusk. The white colour of the new LEDs is also substantially more comfortable for the human eye due to its composition. Another advantage is that it makes yellow and red warning symbols and lights stand out more. Lastly it gives the interior a higher-quality appearance and creates a more pleasant ambiance.

Interior light
The interior lights and footwell lights are supplied with negative potential. This takes the form of a PWM (pulse width-modulated) signal which is altered accordingly with a parameterised dimming time.

Orientation light
The LEDs in the interior light and in the footwell lights are supplied with positive potential. This also takes the form of a PWM (pulse width-modulated) signal which is altered accordingly with a parameterised dimming time.







Safety and exit lighting
The addition of automatic coming home lighting to the exit lighting represents yet another major increase in convenience. Automatic coming home lighting is preselected via the light switch. When the door is opened or the vehicle is unlocked using remote control, the front fog lights, tail lights and licence plate lights come on for 30 seconds to illuminate the surroundings. In vehicles with the Sport Chrono Package Plus, the duration for which the lights stay on can be changed in the "Individual Setting/Light" menu option.

The sun-position sensor in the automatic climate control system monitors the ambient brightness to prevent the lights being switched on unnecessarily.

Bulbs rated at 12V, 10W are used for the safety and exit lighting. These bulbs are activated by the respective door control units.

Power-saving cut-off
The interior lights are supplied centrally with positive potential via terminal 30G. In order to prevent interior lights which are left on permanently from draining the battery, terminal 30G is switched off when the CAN signal "load switch-off" is active. This CAN signal is generated centrally in the driver authorisation controller (PAS - Porsche Access System).
