2-stage Electronic Stability Program (ESP®) with AMG-specific parameter settings[3] The 2-stage Electronic Stability Program (ESP®) can reduce skidding, increase driving safety and adapt the vehicle to the chosen style of driving. To do this, the system constantly compares current driving conditions with the driver's input. If discrepancies are identified, the system applies braking to individual wheels in order to align driver requirements with actual conditions and to prevent the vehicle skidding. In doing this, the parameters for steering angle and lateral acceleration are taken into account.

3-stage Electronic Stability Program (ESP®)[2] The 3-stage Electronic Stability Program (ESP®) can reduce skidding, increase driving safety and adapt the vehicle to the chosen style of driving. Three control strategies are available at the push of a button. With the ESP® switch the driver can choose between "ESP® ON" and "ESP® OFF", as well as an additional ESP® mode for off-road driving.To do this, the system constantly compares current driving conditions with the driver's input. If discrepancies are identified, the system tries to align actual operating conditions to the driver's intentions by applying the brakes to individual wheels, and to prevent the vehicle from skidding. In doing this, the parameters for steering angle, lateral acceleration and yaw rate are taken into account.

ADAPTIVE BRAKE with HOLD function, Hill-Start Assist and brake drying in wet conditions 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 reduced reaction times for drivers in following cars: the adaptive brake lights can make a significant contribution to preventing rear-end collisions by displaying emergency braking signs to vehicles. If the driver brakes hard or initiates emergency braking from a speed greater than 50 km/h, the brake lights flash in order to warn traffic behind. 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 front passenger The airbags for the driver and front passenger provide protection for the head and torso in a collision, and also afford additional stability to the entire body. They are thus able to mitigate the severity of injuries sustained in an accident. The airbags are deployed when the crash sensors detect an impact of sufficient force.

Active Parking Assist including PARKTRONIC[1] Active Parking Assist makes a major contribution to safe and comfortable driving. It helps drivers find a suitable parking space for parallel parking and helps them to park - on bends, too - through active steering intervention. The integral PARKTRONIC feature warns drivers if there are hard-to-spot obstacles in front of the car or behind it.
At speeds of up to 36 km/h Active Parking Assist looks for suitable parking spaces using the ultrasound sensors in the front bumper. The automatic parking space search function is indicated by a "P" symbol in the instrument cluster. If Active Parking Assist has found a parking space, an arrow appears next to the "P". By default, Active Parking Assist searches for parking spaces on the right-hand side of the road. If the indicator on the driver's side is active, parking spaces on the left-hand side are also detected

AMG high-performance brake system[3] The AMG high-performance braking system gives outstanding deceleration performance and sensitivity thanks to the internally ventilated, perforated brake discs. The system comprises 390 x 36 millimeter brake discs (perforated and internally ventilated) with 6-piston brake callipers at the front, and internally ventilated 345 x 26 millimeter brake discs with a single-piston combined floating brake calliper at the rear. The brake callipers are also finished in silver to make them stand out.

Anti-lock braking system (ABS) The anti-lock braking system (ABS) can enhance driving safety, especially in critical braking situations. When braking heavily, ABS can prevent the individual wheels from locking by modulating. This ensures that the vehicle remains directionally stable and can be steered 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) system works together with the 4ETS Electronic Traction System for all-wheel drive. ASR helps to prevent individual wheels spinning or the car sheering out to the side, particularly when moving off on snow, ice or gravel, by reducing the power supplied to individual wheels in a targeted way. If, however, it registers that a wheel is starting to spin, 4ETS applies braking pressure to the wheel in a controlled way until the necessary grip on the driving surface is restored.

The ATTENTION ASSIST driving assistance system can warn the driver when typical signs of drowsiness are detected, and therefore enhances driving safety.The driving characteristics are analysed by the ATTENTION ASSIST system, even when it is switched off. If the system is then subsequently switched on during the journey, the complete trip data from the start is taken into account. ATTENTION ASSIST continuously analyses driving behaviour and steering movements. If the system detects certain steering patterns that frequently accompany drowsiness, it warns the driver visually by displaying the "coffee cup" symbol in the instrument cluster at the same time as emitting audible signals. ATTENTION ASSIST can be activated and deactivated in the main menu of the instrument cluster under "Assistance systems". When switched on, it is active at speeds between 80 and 180 km/h.
ATTENTION ASSIST primarily processes the following elements of information:
- Time of day: is read off the instrument panel.
- Trip duration: is calculated by the ESP® control unit.
- Steering movements: are measured by the steering angle sensor.
- Vehicle speed: is measured by the ESP® control unit.
- Longitudinal and lateral acceleration and yaw rate: are captured by specific sensors.
- Controlling interventions made by the driver: the interventions registered by the system include pressing buttons on the radio, changing settings on the steering wheel column, combination switch, cruise control lever and multifunction steering wheel.

Brake Assist (BAS) can provide assistance to the driver during emergency stops. The system can recognise emergency braking from the speed at which the brake pedal is depressed and can automatically supply full braking power. The anti-lock braking system (ABS) simultaneously meters the braking power up to the slip threshold – the vehicle remains steerable. Once the driver releases the brake pedal, automatic brake boosting is immediately terminated.

COLLISION PREVENTION ASSIST collision warning including Adaptive Brake Assist Too small of a gap between vehicles is the main cause of severe accidents. The newly developed radar-based collision warning system COLLISION PREVENTION ASSIST can improve safety and ride comfort by warning drivers when the gap to preceding vehicles is too small 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. When the system detects the danger of a rear-end collision it can issue a visual and acoustic warning to the driver.
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.

Downhill Speed Regulation (DSR) The Downhill Speed Regulation function boosts active off-road safety and ensures more relaxed driving on downhill slopes. Speeds of between 2 and 18 km/h can be set when negotiating steep descents. This vehicle speed is maintained, within the limits of physical possibilities, with the help of the ESP® control unit as well as the engine and transmission control and by brake actuation. The Downhill Speed Regulation (DSR) function is activated using a switch on the control panel.
| |
Electronic Traction System (4ETS) for all-wheel drive The Electronic Traction System 4ETS can increase safety in critical driving situations: it is a driving dynamics control system which helps maintain traction and handling through appropriate activation of the wheel brakes and engine management.
The Electronic Traction System ETS forms part of ESP® and brakes the drive wheels individually if they start to spin. This means that starting off and accelerating is also possible on slippery surfaces, e.g. when the road is icy on one side. In addition more drive torque is transferred to the wheel(s) that still have traction.

Pedestrian protection with Active Bonnet[2] The active bonnet can reduce the risk of injury to pedestrians and cyclists. If the system identifies a collision, the rear section of the active bonnet rises up by approximately 80 miilimeters by means of pyrotechnics. This produces additional deformation space to absorb the impact energy.

Tail lights with LED fibre optics The LED bicolour tail lamps give the car a striking external appearance and improve active safety in traffic with their fast response.
The taillamp and side marker lamp use LED fibre optic technology and the indicators LED technology, while the brake lamp, reversing lights and rear fog lamp use bulbs.

Intelligent Light System[1] The Intelligent Light System improves visibility in dark conditions by adjusting its bi-xenon headlamps to the current driving situation. So, for example, illumination is wider on a country road; and on motorways it is significantly extended. The system also features enhanced fog lamps as well as active light and cornering light functions. In conjunction with the ON&OFFROAD package, the off-road light can also be switched on if the "Off-road 1" or "Off-road 2" drive program is activated. This swivels the bi-xenon headlamp units 6 degrees outwards. The light is distributed symmetrically and the light output is increased by 3 watts. In addition, the LED cornering lights are turned on permanently while the dynamic bending mode function and the headlamp range adjustment are deactivated.
The integral headlamp cleaning system ensures that headlamps are clean and therefore visibility both on and off the road is better.

PRE-SAFE® system with reversible belt tensioners for driver and front passenger seats, side window closing function When the PRE-SAFE® system detects typical accident risks, it can activate preventive safety systems depending on the driving situation and vehicle equipment. These can help reduce the risk of injury to the vehicle occupants. The PRE-SAFE® system is able to recognise an impending accident because it represents a synergy of active and passive safety features unique to this vehicle class: it systematically accesses the sensors of existing systems such as ESP® or BAS. Their sensors are able to detect typical critical driving situations and provide the appropriate information to the PRE-SAFE® system, thereby enhancing the standard safety systems.
Examples include securing of the driver and front passenger in their seats at an early stage by belt tensioners to prevent undesirable body movements; or the almost complete closure of the side windows and sliding sunroof to protect occupants from any objects entering the vehicle.

The Crosswind Assist can help the driver to keep the vehicle on course, considerably increase the driver's sense of security and prevent inappropriate responses to sudden gusts of wind. With the ESP® sensor system, strong gusts of side wind can be recognised in good time and the brakes can be actuated automatically to correct the vehicle's direction. In this way the system can prevent strong, gusting side winds causing the vehicle to go off course suddenly. Actuation of the brakes on the side of the vehicle facing the wind creates a yaw response which counters the crosswind disturbance. The track offset experienced by the vehicle is reduced as a result.

In a side-on collision of a sufficient force (and other accidents with a high level of lateral dynamics), the risk of an occupant's head smashing against the side of the vehicle or objects entering the vehicle is reduced by the windowbags, which cover the side windows upon inflation. Once released, the windowbag covers the side pane between the A and C-pillars like a curtain. This leads to a large area of the side being covered by the windowbag. The windowbags are inflated at the same time as the sidebags (combined thorax/pelvisbags), as a rule on the side of the vehicle absorbing the side impact.
