Mercedes Benz is among the top names that have been at the forefront of automotive safety for years. With a focus on passenger safety, the brand has introduced numerous features that add to ride comfort. One such feature is the Mercedes-Benz Pre-Safe system that automatically activates in case of an incoming collision.
Moving forward, here are the details of this safety feature, its working and limitations.
What is Mercedes Benz Pre-Safe?
The history of Mercedes Benz depicts the brand’s take on automotive technology and pushing its boundaries. For instance, the Mercedes AI-powered voice assistant offers a human-like interaction with car occupants.
Speaking of the Pre-Safe system, it first came out as a concept in 2002. Later on, the feature first became available on the 220 S-Class 2003 model. Since then, Mercedes Benz has revamped this safety system.
Today, the Mercedes-Benz Pre-Safe is an advanced safety system that activates upon detecting an imminent collision. It proactively prepares the vehicle’s interior to mitigate the effects of an impact through a series of protective measures.
Here is the working of the Mercedes Pre-Safe system. Let’s learn it in detail.
Working of Pre-Safe System
Mercedes-Benz Pre-Safe system incorporates an extensive network of different car sensors placed throughout the vehicle. These sensors continually assess variables such as changes in steering angle, variations in wheel speed and radar signals to detect potential accident scenarios.
When sensors identify any potential danger, such as significant swerving, abrupt braking or an increased likelihood of a collision, the Pre-Safe system activates. It then initiates its protective protocols. These preemptive safety measures are as follows.
Seat Belt Tightening
The system automatically tightens the front car seat belts and prepares the airbags. It ensures that occupants are securely fastened in their seats, which is critical for minimising movement during a collision.
Adjustment of Headrests and Seats
To lessen the risk of injuries like whiplash, Pre-Safe adjusts the front headrests to provide better support. Furthermore, in certain models, it modifies the angle of the seats to place occupants in a more protective posture in the event of a collision.
Cabin Securement
In the case of rollover accidents, the Pre-Safe closes the windows and the sunroof to prevent debris from entering the vehicle. It helps maintain the structural integrity of the cabin.
In addition, the Pre-Safe Brake Assist works with the Mercedes Active Assist Distronic for enhanced safety. Distronic Brake Assist, part of the adaptive cruise control system Distronic Plus, uses radar to keep a set distance from the car ahead.
On detecting a potential collision, such as rapidly approaching the vehicle in front, Pre-Safe steps in. It alerts the driver and prepares the brakes for a faster response.
Advanced Pre-Safe Features for Specific Models
Three advanced features, Pre-Safe Sound, Pre-Safe Impulse Side and Pre-Safe Plus, come as optional additions to the standard Pre-Safe system. They offer further customisation and enhanced safety measures on new and used Mercedes-Benz models in the UAE.
Pre-Safe Sound
This feature introduces a pre-crash ‘pink noise’ that triggers a reflex in the inner ear. It aims to protect occupants’ hearing from the loud noises usually associated with a collision.
Pre-Safe Impulse Side
It uses a collision avoidance system that detects potential side impacts. Upon detection, it inflates a section of the seat side bolsters. This nudges the occupant away from the door to improve side-impact protection.
Pre-Safe Plus
The Mercedes Benz Pre-Safe Plus automatically applies the brakes when a rear-end collision appears imminent. It reduces the severity of whiplash and subsequent collisions. It also activates hazard lights to alert drivers behind. This also naturally enhances overall road safety.
Pre-Safe Functions Limited – What Does it Mean?
When the ‘Pre-Safe Functions Limited’ appears on Mercedes-Benz, it indicates a partial operational status of certain features within the Pre-Safe safety system. This alert may signify several potential issues:
Sensor Malfunction
The Pre-Safe system relies on an array of sensors to identify and prevent different car crashes. That said, any malfunction within these sensors could prompt the alert.
System Malfunction
A malfunction within the Pre-Safe control unit itself could restrict its operational capacity, leading to alert activation.
Environmental Interference
Adverse weather conditions such as heavy rain or dust may obstruct the sensors, consequently triggering the alert.
In such scenarios, consult the Mercedes-Benz owner’s manual for specific instructions on dealing with the alert. In addition, you can seek help from qualified Mercedes-Benz technicians who are equipped to diagnose the problem accurately and suggest necessary repairs. While the vehicle may remain operable with restricted Pre-Safe functionality, prompt resolution of the issue is crucial.
FAQs
What happens when Mercedes-Benz Pre-Safe detects an imminent collision?
When the system detects an imminent collision, it initiates precautionary measures. These include tightening seat belts and adjusting seat positions to enhance occupant protection.
What sensors are used in the Pre-Safe system?
This modern car safety feature uses a sensor network including radar and cameras that scan the car’s surroundings for potential collisions.
Where are the Pre-Safe sensors on Mercedes?
Pre-safe sensors in Mercedes-Benz vehicles are located in key areas such as the front and rear bumpers.
That was all about the Mercedes Benz Pre-Safe system. It offers an added layer of protection by preparing the vehicle and its occupants for potential collisions, ultimately reducing the risk of injury.
Besides, many new Mercedes Benz models such as the E-Class and S-class are available with this safety feature.
