The 4-way lumbar support improves seating comfort and ergonomics. The backrest curvature can be individually adjusted to meet the needs of the driver and front passenger, promoting an ergonomic seating position. Two air cushions are integrated in the backrests of both front seats. Via two control valves they can be inflated or deflated as required, facilitating individually tailored support for the lumbar spine. The height of the air cushions is also adjustable. Lumbar support adjustment is carried out by means of a 4-way switch on the outside of the seat cushion.

The Stowage Space package provides a variety of organisational aids. It includes a spectacles compartment in the overhead control panel, a stowage box under the front seats, folding tables on the driver’s and front-passenger seat backrests and a net pocket in the front-passenger footwell.

The automatic child seat recognition system detects child seats with a transponder from the Mercedes-Benz accessories range and automatically deactivates the front passenger airbag.

An aerial integrated in the front-passenger seat sends signals. Transponders in the special child seat models from the Mercedes-Benz accessories range detect these signals and send a feedback signal. Based on this feedback signal, the automatic child seat recognition system deactivates the front-passenger airbag, regardless of whether the child seat is installed facing the front or rear. An indicator lamp lights up to confirm that the airbag has been deactivated. The belt tensioner and the other airbags on the front-passenger side – such as pelvisbags or a windowbag – remain active in order to protect the child. The front-passenger airbag is reactivated automatically after the child seat has been removed.

The EASY-VARIO-PLUS system provides the highest level of variability for loading, enables the transport of even very bulky objects and a flexible, swift re-arrangement of the vehicle interior. The vehicle interior can be quickly and conveniently converted to transport large and bulky items.

The Load Compartment package which is automatically included in the EASY-VARIO-PLUS system includes a 12 V socket and a folding box in the load compartment along with a height-adjustable load compartment floor. It can be set to two different heights. In the upper position it creates a continuous surface with the load compartment sill and allows for easier loading and unloading. Folding the rear seat backrests forward further expands the load area. In the lower position the load compartment becomes larger and it can also transport particularly tall objects.

The entire rear seat unit is adjustable fore-and-aft, and can be moved almost to the front seats to enlarge the load compartment. The rake of the rear backrest is adjustable, with a 90-degree cargo position. The front passenger seat can be folded forward. In this way its backrest can be used as a table by the rear passengers, or the space created can be used to transport particularly long items. To enhance the comfort of rear seat occupants, the EASY-VARIO-PLUS system also includes an armrest with a twin cup holder which can be folded down from the seat backrest.

The rear seats with integral child seats provide appropriate protection for children. The integrated child seats are incorporated into the seat cushions at the right and left of the rear seat unit. A hinge mechanism allows the seats to be pivoted upwards and locked into place. Children aged 4 to 12 years may be secured with the standard three-point seat belts, while children aged 2 to 4 years must be additionally secured with a special padded play table. This play table, and therefore the child, is also secured by means of the standard seat belt.

The ISOFIX child seat attachment system is a quick, convenient, non-vehicle-specific system conforming to ISO standards. It allows quick and easy child seat attachment in the rear. Its fixed anchorage points ensure a high degree of protection in the event of an accident.

A special ISOFIX child seat engages in the attachment points housed in the lower area of the backrest. This creates a rigid connection with the vehicle structure, meaning that seat movements caused by slack or incorrectly fitted seat belts can be avoided. TopTether is an additional safeguard that is attached at a point behind the rear head restraints. It further reduces the risk of the child seat tilting forwards in the event of a crash.

The air conditioning system has a heating and ventilation system and a refrigeration system. A rotary switch can be used to set the desired temperature for the interior. Depending on the pre-selected temperature and the desired air distribution the air is heated, or if the air conditioning is switched on it can be cooled.

Activating the recirculation function means that no external air is blown into the vehicle interior. To avoid the windows steaming up, air recirculation is automatically deactivated in line with temperature and settings. Depending on vehicle equipment, holding down the air recirculation button closes the side windows and sunroof. Fresh air runs through the dust filter which improves the air quality.

With the THERMOTRONIC luxury automatic climate control, you and your front passenger can set individually preferred temperatures at any time. The system also takes outside parameters into account, including temperature, humidity, and the intensity and angle of incidence of the sun’s rays. A dust filter and an activated charcoal filter make sure that pollutants remain outside, as far as possible. Sensors also register the quality of the outside air. If it falls below a certain level, the ventilation flaps are automatically closed.

THERMOTRONIC is an extension of the standard-specification air conditioning system. As well as taking into account influencing factors such as the sun’s intensity, air quality, humidity of the outside air taken in etc., the temperature and air distribution for multiple zones (driver and front passenger) can be individually controlled. A sophisticated sensor system enables automatic control of the interior air conditioning requirements: as the sun’s intensity increases, the solar sensor adjusts the fan speed and temperature to maintain the set temperature.

Other functions:

The comfort multifunction steering wheel enables an extensive access to a variety of telematics and vehicle functions/settings. All information relevant to the vehicle is shown in the instrument cluster TFT colour display. The luxury multifunction steering wheel has 12 function buttons and a high-resolution 11.4-cm colour display.

The 3-spoke multifunction sports steering wheel with twelve buttons and display in the instrument cluster is controlled by means of two clusters of buttons on the steering wheel. The left-hand cluster is used to operate the menus, while the right-hand cluster controls the audio and telephone telematics functions. The "Settings" menu allows the driver to adjust various parameters, such as light and instrument cluster settings. Optional extras which are not fitted in the vehicle are skipped.

The right-hand button on the luxury multifunction steering wheel in the instrument cluster can be used to select other settings. For example the buttons "pick up phone" or "hang up phone" can be used to accept, end or reject a phone call, and the +/- volume controls also control the volume for the radio and voice instructions.

The Load Compartment package includes a height-adjustable load compartment floor, which provides a practical and convenient addition. A folding box provides additional stowage capacity, allows the load compartment to be adjusted to the current load situation at any time and provides more organisation and safety. There is also a socket (12 V) in the load compartment.

The Light and Sight package improves safety and the driver’s perception of traffic conditions, especially in the dark and in poor weather, and enhances the interior’s high-class appeal.

It includes for example safety-related features such as an automatically dimming interior mirror with additional lights, a windscreen wiper with rain sensor and larger washer fluid reservoir, exit and warning lights for the driver’s and front-passenger doors and a warning and background light on the tailgate.

The integral ambient lighting in the dashboard trim and in the door recesses and door pulls accentuates the interior design of the new B-Class stylishly and exclusively. The pleasant impression gets a further boost from sunblinds with illuminated vanity mirror, footwell lighting for the driver, front passenger and in the rear, separately controlled reading lights in the rear on the left and right sides and a downlighter for the rear.

With the memory package the driver’s seat, driver’s head restraint and exterior mirror can be adjusted electrically to any position. The settings can be stored and recalled again at any time. The front-passenger mirror swivels automatically downwards when reverse is engaged (parking position).

In the memory programming, which can recall three individual positions, all seat setting options, such as fore-and-aft position, angle and height of the seats as well as backrest angle and head restraint are included. With the ergonomic switches with intuitive operation the driver can select the best possible seat position using infinitely variable settings for the seat and head restraint. Quick and exact resetting to the previously saved seat and head restraint positions make frequent driver changes much more convenient.

The panoramic sliding sunroof creates a transparent surface area twice the size of conventional sliding glass sunroofs and creates an interior with a particularly bright and friendly ambience.

It consists of a fixed panoramic glass roof and an electrically operated glass sunroof which slides over the exterior of the roof. The transparent surface area is very large and lets in plenty of light. When the sunroof is opened using the switch, the wind deflector is first raised. Then the sunroof is raised upwards and slid backwards over the fixed glass roof section at the rear. In addition, two motorised sunblinds are housed in the central cross strut of the panoramic sunroof, which can be extended simultaneously, one forward and the other towards the rear.

The electric seat heating allows for multi-level individual heating of the front seats. The pushbutton 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, or it can be also be switched off manually at any time. Seat heating is also switched off automatically if the battery charge is too low.
 

The Seat Comfort package improves seat comfort on journeys of all lengths, even longer ones, by providing the seats with more options for ergonomic individualisation and for adjustment to the desired seat position. The package includes height adjustment for the front-passenger seat and seat cushion inclination adjustment for both front seats.
