Most accidents begin long before the impact. For example, with poor visibility or unforeseeable hazards. This is why the Tourismo is equipped with a number of safety features that help master critical driving situations.
Safe. Safer. Mercedes-Benz.
Starting with the ergonomic driver's workplace. The driver can comfortably reach all controls and has a perfect view of all the instruments. The wide-angle exterior mirrors guarantee more safety through better all-round vision.
While on the move electronic assistants support the driver. The anti-lock braking system (ABS) minimises the risk of the wheels locking when braking. The electronic-pneumatic brake control (EBS) significantly shortens the stopping distance, as the brakes are actuated faster and more precisely. The Acceleration Skid Control (ASR) system provides additional safety. It helps the driver to minimise the risk of the rear of the vehicle (rear-wheel drive) breaking out laterally when accelerating. ABS, EBS and ASR form the basis for further developed electronic safety systems such as the Electronic Stability Program (ESP®) or the Brake Assist System (BAS), with which the Tourismo is also equipped.
MirrorCam.
The modern MirrorCam system provides a clear and full view of the road traffic. Equipped with high-resolution cameras, the driving safety is improved and the risk of accidents is minimised. The extended field of vision enables the driver to see pedestrians, cyclists and other road users in the surrounding area. This eliminates the blind spot when turning right.
Depending on the vehicle, the images are displayed on 7" and 15" monitors. The two high-resolution displays show the different fields of vision. The photodiodes integrated in the monitors detect the incident light and adjust the brightness of the respective monitor individually. To make it easier for the driver to evaluate the images, the 15" variants have three different guide lines. Together with the permanently calibrated vehicle end line, the distance line assists the driver in assessing approaching objects. The Overtaking Assist overlay is activated from a speed of 10 km/h with flashing, in order to safely assist overtaking or turning. In addition, the display for Blind Spot Assist is installed in the monitor.
Traffic Sign Assist (TSA).
The innovative Traffic Sign Assist offers maximum safety and comfort on the road. Thanks to GPS and camera support, the vehicle speed is constantly compared with the current traffic regulations.
The system is designed to provide dedicated and appropriate feedback if the permitted speed is exceeded. Thanks to the state-of-the-art instrument cluster, the driver receives both visual and audible signals that immediately draw attention to the speed.
Sideguard Assist 2.
Sideguard Assist 2 is a safety assistance system that supports the driver in critical situations when turning right or turning left when visibility is possibly restricted. The system is designed to help detect moving obstacles within the system limits, and warns the driver so as to avoid critical situations or reduce the consequences of accidents when turning off or changing lanes.
The side areas of the vehicle are constantly monitored. As a result, vehicles, pedestrians or cyclists who may be in the blind spot are detected on both the front passenger side and the driver’s side. The radar system precisely detects the movements and warns the driver of possible collisions. The intuitive user interface and clear warnings allow the driver to drive safely and relaxed.
Active Brake Assist 6.
The emergency braking system ABA 6 assists the driver by automatically initiating emergency braking if there is a risk of rear-impact collision with vehicles in front or stationary obstacles. It also detects moving or stationary persons and cyclists in front of the vehicle. The system reacts to this with an acoustic and visual warning to the driver as well as an automatically initiated partial braking or emergency braking.
With Active Brake Assist 6, accidents can be avoided even more reliably. The system covers the entire vehicle speed range and is active in the background. Up to a speed of 60 km/h, pedestrians and cyclists can react. The ABA 6 safety system reacts to crossing and oncoming pedestrians and moving cyclists in the vehicle’s own lane with automatic emergency braking. This automation also provides increased safety for cyclists, whether in intercity or urban traffic.
Front Collision Guard (FCG).
Front Collision Guard offers increased safety in the event of a head-on collision thanks to a crossmember behind which crash elements are located. Their absorber structure converts the impact energy into deformation energy. The crossmember serves as a reliable underride guard. As the driver's seat is mounted on a solid frame part, this can move completely to the rear in the event of a serious head-on collision and thus better preserve the driver's safe space.
The patented technology includes a multi-part cross section as underride guard behind the bumper with the idea of protecting other road users, e.g. preventing a car from going under the bus. The front-end structure behind this cross section consists of crash elements that can selectively dissipate energy in the event of a collision. In addition, the driver's area, including steering, pedals and seat, is located on a massive frame section that is displaced rearward as a complete unit in the event of a serious head-on collision, thereby increasing the survival space by vital centimetres.
The FCG fulfils the requirements of the underride guard according to ECE-R 93, as well as legal norms for pendulum impact in buses. Moreover, the FCG already meets future statutory standards for pendulum impact tests on buses.
Lane Assist (SPA).
With the aid of a camera system behind the windshield, the Lane Departure Warning system detects when the vehicle unintentionally leaves a marked lane. As soon as the vehicle crosses the markings, the driver is warned by a clear vibration on the corresponding side of the driver's seat.
The LDWS is activated from a speed of 40 mph (60 km/h). The lane assist system is switched off when the turn signal is activated, for example when the driver initiates a deliberate lane change. The system can be deactivated in the ICUC menu, e.g. in a construction site.
A small camera behind the windshield uses boundary lines to record the road directly in front of the vehicle. If the vehicle is about to cross any of the markings without a turn signal being activated, the driver is alerted by a pulsation in the seat. The camera determines the instant of warning based on the width of the lane, the distance to the marking line, and the speed of approach to the marking. The LDWS becomes active above a speed of 40 mph (60 km/h); it is switched off by operating the turn signal, for example when initiating a deliberate change of lane.
Sideguard Assist 2 & Frontguard Assist.
Electronic Stability Program (ESP®).
The Electronic Stability Program (ESP®) significantly reduces the risk of the vehicle skidding and tipping over by selectively braking individual wheels or by braking the vehicle as a whole.
High-performance electronics monitor the signals from the ESP® sensors and constantly determine whether the steering commands of the driver match the actual movements of the vehicle. If the values deviate from one another, the system decreases the engine torque to restore stability to the vehicle. If this is not sufficient, it also brakes individual wheels or the entire vehicle. The driver’s request for deceleration is observed at all times.
The ESP contains the ASR safety system, which prevents excessive wheel slip during acceleration. The ESP brake interventions are also secondary to the ABS function, thereby avoiding locked wheels. The ESP can be switched off and on again using a button on the instrument panel; the switch-off is indicated by a check lamp. (USA: only the ASR function contained in the ESP can be deactivated). ESP (USA: ASR) is automatically switched back on after the ignition is switched off/on.
Tyre Pressure Monitoring (TPM).
The wireless tyre pressure monitoring with indication in the multifunctional display is an electronic safety system that permanently monitors the air pressure of all tyres. Tyre pressure losses are displayed within the system limits.
The right tyre pressure contributes to driving safety and significantly reduced fuel consumption. Even a tyre pressure set 0.5 bar too low can increase fuel consumption by up to 5%. The wheel electronics are positioned on the valve on the inside of the rim. The sensors record the data relevant to the tyre pressure and transmit it to the display instrument.
Legal notice on active safety assistance systems: Emergency braking systems and other safety assistance systems can support the driver and mitigate the severity of accidents or prevent accidents in critical driving situations under optimal conditions, within the system limits. However, irrespective of this, the driver has a duty to adapt his driving behaviour and in particular his speed to the traffic and weather conditions and to be attentive at all times. This applies in particular to special situations such as icy or wet roads, rain, crosswind, poor visibility, snowfall, fog, etc. Consequently, the driver, as the driver of the vehicle, has the responsibility for the entire driving situation at all times and must not rely exclusively on the safety assistance systems.
