ADAPTIVE BRAKE with HOLD function, dry braking in the wet and hill start assist
The ADAPTIVE BRAKE system improves ride comfort and safety by helping to perform critical braking manoeuvres more safely with the basic function of the ABS anti-lock braking system, while convenience functions support the driver in everyday driving situations.
- Supportive HOLD function: the ADAPTIVE BRAKE system's HOLD function, which is activated by briefly depressing the brake pedal, prevents unintentional rolling when stopped at a traffic light or in stop-and-go traffic.
- Extra help: the Hill-Start Assist function prevents the vehicle from rolling back unexpectedly on uphill gradients when moving from the brake to the accelerator pedal.
- Braking effect with no delay: The "brake drying" function removes the film of water that forms on the brake discs in wet conditions.
- For an even quicker response: With the "Priming" option, the brake linings on the brake discs are primed as soon as the driver takes his foot off the accelerator quickly.
Adaptive brake lights, flashing
Improved perceptual safety and shorter reaction times for drivers in vehicles following behind: The adaptive brake light can make a significant contribution towards preventing rear-end collisions by indicating to following traffic that an emergency braking manoeuvre is taking place.
If the driver makes an emergency stop from a speed greater than 50 km/h, the brake lights flash in order to warn following traffic. If the vehicle comes to a stop from a speed greater than 70 km/h, the hazard warning lamps are switched on automatically.
Airbags for driver and passenger
The driver and front passenger airbags can help to protect the upper torso and head in a collision – as well as providing additional stability for the entire body. They are thus able to mitigate the severity of injuries sustained in an accident. If the crash sensors detect a collision of a certain strength, the airbags are deployed.
Anti-lock braking system (ABS)
The anti-lock braking system (ABS) enhances driving safety, especially when braking for hazards. During hard braking the anti-lock braking system reduces wheel lock-up by modulating the braking pressure of the individual wheels.
This ensures that the vehicle remains directionally stable and steerable while maintaining maximum braking power.
In other words: ABS allows the driver to brake and steer simultaneously – allowing precise evasive manoeuvring – in order to avoid an accident.
Acceleration skid control (ASR)
The acceleration skid control (ASR) ensures that the wheels do not spin when accelerating. Especially when moving off on snow, ice and loose chippings, the acceleration skid control prevents individual wheels from spinning and the vehicle from sliding out to the side.
The system uses speed sensors to monitor the slip characteristics of the wheels. If the system senses a wheel is starting to spin, the acceleration skid control corrects the wheel speed by braking and intervening in the engine management system, thus reducing wheel slip and wheel spin.
The ATTENTION ASSIST function is particularly helpful on long journeys and when driving at night; the system warns the driver if it detects signs of failing attention and increasing weariness.
At speeds of between 60 and 200 km/h, ATTENTION ASSIST warns the driver visually and audibly as soon as it detects any signs of drowsiness or inattention.

BAS Brake Assist system with brake force boost upon detection of emergency stop
The BAS Brake Assist system can recognise emergency braking from the speed at which the braking pedal is depressed and can automatically supply full braking power.
The anti-lock braking system (ABS) then meters the braking power up to the slip threshold, which is how steering control is maintained. Once the driver releases the brake pedal, automatic brake boosting is immediately terminated.
Brake wear warning display
COLLISION PREVENTION ASSIST collision warning including Adaptive Brake Assist
Too small of a gap between vehicles is one of the main causes of severe accidents. The newly developed radar-based COLLISION PREVENTION ASSIST collision warning system can enhance safety and driving comfort by warning the driver of following too closely or of stationary obstacles and can support the driver's braking when it detects danger.
When travelling at speeds of more than 7 km/h, the system can recognise insufficient gaps to vehicles ahead as well as stationary objects. The forward collision warning is emitted as soon as the vehicle approaches any vehicle detected to the front at a high speed or acceleration. In this case the driver can be warned visually and audibly.
If the system detects a danger and the driver applies the brakes at the same time, Adaptive Brake Assist can intervene for good measure: It then provides precisely the right amount of brake pressure that is needed ideally to avoid an impending collision. COLLISION PREVENTION ASSIST is an innovative component of the Integral Safety Concept of Mercedes-Benz.
ESP® Electronic Stability Program
In critical situations, the Electronic Stability Program (ESP®) can help to stabilise the vehicle by applying a braking force to individual wheels, and adjusting engine output. By carrying out targeted braking interventions at individual wheels ESP® can prevent both over- and understeer, thus enhancing handling safety.
If the ESP® system detects a critical situation, it applies the brakes systematically to one or more wheels according to the situation. Should the system consider it necessary, it will also make an automatic adjustment to engine torque. In this way ESP® helps the driver to stabilise the vehicle within the laws of physics – particularly when cornering and during sudden evasive manoeuvres.
- Central feature: the yaw-rate sensor continuously tracks vehicle movement around its vertical axis. ESP® compares the actual value measured with the desired value based on the driver's steering input and the vehicle's speed. The instant the vehicle deviates from the ideal line, ESP® intervenes by working to counteract any swerving movements as they occur.
- Always the best possible traction: the integrated ASR traction control system additionally controls wheel slip when accelerating with interventions in the engine management system.
- Enhanced safety: ABS as an integral component of ESP® helps to prevent the wheels from locking and to maintain their steering function.
- Reliable basic functions: ESP® rounds off the functions of the anti-lock braking system (ABS) and acceleration skid control (ASR) to help with driving stability.
The headlamp assist system reduces the strain on the driver as it can automatically switch on low-beam headlamps, tail lamps and number plate illumination when it gets dark outside. The assistance system performs this task even when it's raining or snowing by electronically detecting the cycles of the windscreen wipers.

Pedestrian protection with active bonnet (reversible)
If the system detects a collision, actuators are activated using pyrotechnics and the engine bonnet lifts up using spring force.Additional deformation space is created between the soft bonnet and the hard assembly in the engine compartment. This can reduce the collision energy as a result and lower the risk of severe injuries. The system can then no longer be initiated, and must be brought to a specialist workshop to be repaired.
The headbags for the driver and front passenger were specially designed for the requirements of a cabriolet and in the event of a crash they can provide particularly effective protection to occupants, regardless of their body size. The side protection system, consisting of a headbag, sidebag and pelvisbag, tailors the protective effect to the individual parts of the body. The headbags are built into the door panelling at beltline level.
Tail lights with LED technology
The LED tail lamps create an unmistakable night design. All functions are realised with LEDs and to some extent with fibre optics technology. This allows to make LEDs in certain areas of the tail lamp glow at different intensities depending on the light function. The lenses are carried out in red and white.
Heated rear window with timer control
The heated rear window prevents the window from icing or misting up due to moisture, ensuring clear visibility to the rear. The timer adjusts the operating time of the heating to the outside temperature and the road speed.
ISOFIX child seat attachment points and TopTether fastening points in rear backrest on the upper left and right
The ISOFIX child seat attachment points are designed for child seats that use the ISOFIX attachment system. The ease with which this system allows child seats to be secured lowers the risk of their incorrect attachment. A further belt can be attached to each of the additional Top Tether attachment points, which prevents the child seat from tipping forward and therefore makes the child seat attachment system even more stable.
The kneebag installed as standard on the driver’s side helps to protect the legs during impact and also stabilises the entire body.
It can thus help mitigate the potential severity of injuries sustained in an accident.
If the crash sensors detect a collision of a certain strength, the kneebag is deployed.
Headlamp range adjustment
The headlamp beam control adjusts the light cones of the headlamps to the vehicle’s pitch (pitch angle). In this way the lighting of the road ahead is always optimal for the driver, and oncoming road users and vehicles in front are not blinded.
NECK-PRO head restraints for front seats
Activated when the system registers a rear-end collision, NECK-PRO luxury head restraints for driver and front passenger can reduce the risk of sustaining a whiplash injury.If a collision occurs, they ensure that the head receives support and the load on the spine is reduced at an earlier stage by employing a spring mechanism to move the head restraints forwards and upwards. After their deployment the head restraints can be returned to their original position by hand.
PRE-SAFE® system with reversible belt tensioners for driver's and passenger's seat, side window closing function
The preventive PRE-SAFE® occupant protection system can recognise critical driving situations and, if necessary, pre-emptively activate reversible safety systems to help reduce the risk of injury to the vehicle occupants.
This is based on PRE-SAFE® continuously monitoring sensor data from systems such as ESP® and BAS and identifying driving situations such as oversteer/understeer and emergency stops.
If the typical characteristics of a critical driving situation are identified, safety systems can respond within a fraction of a second. The electronic belt tensioners are activated, the electrically adjustable front-passenger seat (only in conjunction with Memory Package) is moved to a more "favourable" crash position, and the side windows are closed automatically.
Tyre pressure loss warning system
The tyre pressure loss warning system can promptly inform the driver when it recognises an uneven drop in pressure in the individual tyres, which helps to prevent accidents. The system monitors the rotational speed of the individual wheels and can recognise significant losses in pressure depending on any changes. The warning is provided via a display in the instrument cluster.
Power steering with safety steering column
3-point seat belts including automatic belt-height adjustment, reversible belt force limiters and tensioners for driver and front passenger
Front sidebags and pelvisbags
The sidebags and pelvisbags fitted as standard for the driver and front passenger provide protection to the thorax and pelvis area in the event of a side impact, and also afford additional stability to the entire body.Consequently they can mitigate the severity of injuries sustained in an accident.
They are triggered when the central control unit and the side satellite sensors register acceleration or deceleration forces acting on the vehicle in excess of a certain threshold. The sidebags deploy at chest height between the vehicle side and the occupant.<br /><br />The pelvisbag is deployed in the space between the front-seat occupants’ pelvic region and the door panelling.
The pelvisbag then braces itself against the impact area, pushing the occupant’s pelvic region away from the door panelling at a very early stage of the collision.<br /><br />Sidebags are available as an option for the rear-seat passengers.
Seat occupancy sensor for front passenger seat
The STEER CONTROL assistance system can boost safety by providing corrective intervention in the event of oversteering and braking manoeuvres on different road surfaces.
The ESP® control unit calculates the additional steering torque required for the respective situation. The electric power assist (EPS) then performs the appropriate steering command. If the vehicle starts to skid, the system can help the driver to countersteer in the right direction with a perceptible pulsation of the steering wheel.
Partial LED headlamps, incl. daytime running lamps and position markers
Headlamps, daytime running lamps and the position light which use LEDs are less dazzling to road traffic, which helps improve safety. They can be switched on very quickly and also have a very long operating life. In addition, depending on the function, their energy requirements are considerably lower than those of conventional headlamps, which has a positive effect on the vehicle's energy consumption.
Cruise control with SPEEDTRONIC variable speed limiter
Relaxed driving, enhanced ride comfort and a driving style that saves on fuel, particularly on long journeys. The cruise control function allows the driver to set a desired cruising speed. The integrated variable speed limiter (SPEEDTRONIC) enables the driver to set a desired maximum speed, for example when limits are in force or in 30 km/h zones.
The speed limit is selected in increments of one or ten km/h up to the top speed with the control lever, and is displayed in the instrument cluster. If the preset limit is exceeded, e.g. on downhill stretches, the system autonomously shifts the automatic transmission down a gear and applies the brakes to a certain extent. However, if the braking effect is not sufficient, a warning tone alerts the driver that the service brake must also be applied in order to stick to the desired speed limit.
The variable speed limiter function is an additional function to the familiar cruise-control functions, and can be activated using the cruise control lever. A yellow LED light on the switch and a symbol in the instrument cluster indicate that cruise control mode is turned off and Speed Limit Assist is activated. The speed limiter function is switched off by returning the lever to cruise-control mode, by flicking it to the "OFF" position or by kickdown.
Automatic roll-over protection, integrated into rear head restraints
The roof frame structure of the A-pillars is particularly stable. The A-pillars have been reinforced with tubing, offering effective occupant protection together with the roll-over bars in case of an overturn. The roll-over bars’ cassettes are fully integrated in the head restraints on the rear seats and fastened to the area behind the rear seat backrest in the bodyshell. They can be extended in fractions of a second as soon as the airbag control system’s crash sensors detect the risk of an accident.
Warning buzzer and warning indicator in instrument cluster if seat belts are not fastened, parking lamps not switched off or parking brake not applied.
Acoustic warning alerts driver if vehicle lighting is not switched off
Electronic immobiliser, incl. locking system with three-channel remote control, visual lock confirmation and emergency opening (recognised by AZT and TÜV)
Central locking with interior switch, automatic locking (can be deactivated) and crash sensor with emergency opening
The central locking system can increase safety, as it can lock all doors automatically when moving off. Vehicle occupants can, however, exit the vehicle quickly in the event of an accident, thanks to the emergency opening initiated by crash sensors.
Opening a door or operating the interior central locking switch unlocks the doors. If the vehicle is unlocked using the electronic key but neither a door nor the tailgate is opened before 40 seconds have elapsed, the vehicle is locked once again.
Above a speed of 3 km/h the tailgate is automatically locked, and above a speed of 15 km/h the doors are locked, too. If the crash sensor registers an accident, all the doors and the tailgate are unlocked to enable occupants to exit the vehicle swiftly.
