General
The front lights and tail lights play an important role in styling the
appearance of the new Cayenne models and add to the new, dynamic
and sporty exterior design.
A battery charge management system (integrated in the vehicle elec-
trical system control unit) is used to ensure optimized battery charging.
Increasing the charge voltage at low temperatures not only improves
battery recharging in the winter but also ensures better overload protec-
tion in the summer. These measures eliminate the need for the auxiliary
battery, which had been available up to now as an option. Also, the
capacity loss of the battery is compensated for even more quickly after
starting the vehicle.
This section will describe the design and technical functions of the
enhanced electrical systems in the new Cayenne models.
Lighting System
The new front lights on all new Cayenne models have a flatter basic
shape, which makes all new Cayenne models look wider. The fact that
the mid-point of the outer light unit for the headlights has been shifted
further out also adds to this look.
The direction indicator and marker light are positioned separately in bar-
shaped light units at the edge of the outer air intakes. They are
arranged vertically on the Cayenne and Cayenne S, and horizontally on
the Cayenne Turbo. The arrangement of the lights for the top model is
based on the design used on the current 911 Turbo. As a result, the
new Cayenne Turbo is easily recognizable, even at night. The fog lights
are round and are located low down and at the far outer sides of the
front end in accordance with their intended function. These round off the
sporty look of the new Cayenne models and their low position ensures
optimal illumination of the road in conditions of poor visibility.
The tail lights have also been redesigned with LED technology used for
the rear and brake lights. This is not just another optical highlight of the
new Cayenne models, but actively contributes to improving safety. In
addition to the white backup lights, the shape of the rear lights has also
been adapted to suit the new rear end design.
