The ambient lighting provides a pleasant indirect lighting effect inside the vehicle at night. Luminous surfaces on the instrument panel, behind the front door sill panels and under the door trim elements create an incomparable atmosphere.
In addition, fibre-optic cables and LEDs which are controlled independently of the background light make it easier to find your way around the vehicle when it's dark outside. Exclusive ambient lighting, which can be dimmed to any level and has the three colour schemes of "solar" (amber-coloured), "neutral" (white) and "polar" (ice blue), emphasises the interior design to ensure pleasant light conditions for night driving. In addition, the cup holder in the front and the outlets for the automatic climate control in the instrument panel are illuminated. There is also a reading lamp in the 3rd seating row.
The designo Exclusive package, through its stylish and perfectly matched appointments, gives the vehicle a particularly enhanced sense of perceived value and exclusivity.
The exclusive details of this package have been stylishly matched to each other and are available in the colours marron, black and porcelain. The designo Exclusive package contains high-class appointments which offer wide-ranging possibilities to further individualise your vehicle.
THERMATIC automatic climate control provides individual temperatures and a pleasant climate in the vehicle interior. The desired temperature and air distribution for the left and right-hand sides of the interior can separately regulated for the two zones. In addition, a special filter ensures pleasant air quality by absorbing dust particles from the outside air.
The THERMOTRONIC automatic climate control system allows the driver and passenger to adapt the climate in their respective seats to suit their individual requirements – independently of each other. The system keeps the temperature at the desired level automatically, even in strong sunlight. To this end, sensors register the temperature inside and outside the vehicle, controlling the heating, cooling and fan for each temperature zone individually, according to requirements.
To suit every taste: there are three climate styles (DIFFUSE, MEDIUM and FOCUS) available for selection in automatic mode. You can use these styles to adjust the interior climate to your individual preferences. Factors such as outside temperature, humidity and sunlight are taken into account. A diffuser panel on the dashboard reduces draughts.
The air conditioning in the rear complementing the THERMOTRONIC automatic climate control makes climate control in the rear of the vehicle even better; and it can be controlled by the occupants in the rear.
When the automatic climate control is activated, the desired temperature and air outlet speed can be selected using the control unit in the rear. A control unit is located behind the centre armrest for setting the desired temperature and air outlet speed for the centre air outlets. With the aid of the controls, the desired temperature and airflow can be set by the rear passengers.
The memory package in front makes frequent change of drivers much easier. It stores the individual settings for the front seats for up to three people. The switch for this is in an easily visible position in the seat console.
As soon as a driver selects a setting with the touch of a button, electric controls automatically set the seat, exterior mirrors and steering column back to the previously saved positions. The four-way lumbar support provides even more comfort. At the push of a button, the backrest curvature of the front seats can be set to meet individual passenger requirements and provide anatomically appropriate support for the spine in the lumbar area.
With a view to supporting the back in particular, the contour of the multicontour seat can be adjusted to suit the individual requirements of the driver and the front passenger. This is done by regulating the air pressure in the air chambers in the multicontour seat.
The multicontour seats provide 4-way lumbar support, adjustable seat side bolsters in the backrest to give optimum lateral support,<br />seat cushion depth adjustment to support the thighs and a massage function with different settings (for speed, intensity etc.).
The electric seat heating allows graduated and individual heating of the front seats. The push-button switch control for each seat can be set to normal or rapid heating.
In the rapid heating setting, the system automatically changes to "normal" mode after approx. 5 minutes. The seat heating is automatically switched off completely after around 30 minutes. It can be also be switched off earlier than this manually Seat heating is also switched off automatically if the battery charge is too low.
The electric seat heating allows the rear seats to be heated to the desired level at one of several settings. It heats cold seats immediately, even before the car's heating system becomes effective, enhances the occupants' comfort on cold days and allows the front seats to be heated separately.
The push-button switch control for each seat can be set to normal or rapid heating. If rapid heating has been selected, the system automatically changes to "normal" mode after approx. 5 minutes. The seat heating is automatically switched off completely after around 30 minutes. It can be also be switched off earlier than this manually. Seat heating is also switched off automatically if the battery charge is too low.
The climatised seats improve ride comfort and reduce transpiration thanks to a pleasant air flow and selectable seat heating. Fans integrated in the seat upholstery uniformly distribute a flow of air in three intensity levels under the leather backrest and cushion covers.
The air flows through the fine perforation and quickly cools down the surface of the seats to a pleasant temperature – even if the vehicle has been heated by an intense amount of sunlight for a longer period of time. On cold days you can turn on the three-level adjustable seat heating, which guarantees together with the air flow that wet clothes dry faster.
