Mercedes manufacturers continue to bring innovative features in their modern models that can fulfill the requirements of customers according to the latest advancements.
One such feature introduced in the Mercedes model is the “PRE-SAFE System” which protects the passengers in case of sudden collision. In this comprehensive guide, we will look into the reasons why the warning signal, “PRE SAFE Functions Limited” appears on the dashboard and the possible solution to clear this warning.
One should address the potential causes of the problems and take preventive steps, get guidance from the manufacturer manual, or seek professional help to maintain the customer’s safety.
PRE-SAFE Function Purpose:
This special feature is updated in the recent models of Mercedes as it prepares the vehicle for unexpected crashes. The PRESAFE system comprises a combination of radars, cameras, and sensors to sense any accident so that preventive measures can be carried out beforehand.
This system is specialized to perform certain functions such as tightening seat belts, adjusting headrests, and closing windows. This feature is considered to be the best advancement in the Mercedes model but its function is affected when the “PRESAFE Functions Limited” warning appears on the dashboard.
PRE-SAFE Warning Message:
This message temporarily reduces or disables the functioning of certain components. This warning usually appears on the dashboard of the latest models of Mercedes such as CLA 250, E350, A-Class, A180, and E-Class. It is advised that vehicle owners must not overlook such warnings and take productive measures in time as the working efficiency of their vehicle is directly related to such systems.
5 Reasons For “PRE-SAFE Functions Limited” Warning:
Several factors contribute to displaying such messages on the dashboard. Some of the factors are listed below:
1. Sensor Malfunction:
A basic PRESAFE system is composed of a network of radars, cameras, and sensors that work in coordination to perform related functions. If any of these components undergo malfunctioning such as the sensor becoming blocked then the system loses its ability to recognize and correspond to critical conditions.
2. Faulty Wiring or Connections:
If the system has a faulty electric system like if the wiring is damaged at some point or the connections are weak the system finds it difficult to share information with the sensor leading to system malfunctioning.
3. Software Glitches:
The main functioning of this PRESAFE Function depends entirely on the performance of the software. If there are software glitches or errors in the programming code, a warning signal appears on the dashboard.
4. Low Battery Voltage:
For optimum working of the PRE SAFE system, the battery voltage must be sufficient. If you want to save energy for important operations, the PRE SAFE system should be disabled when the vehicle’s battery voltage is low.
5. Problems with System Calibration:
To ensure accurate detection and response for unexpected collisions, the PRESAFE system should be properly calibrated. The warning signals appear as soon as the calibration parameters are not followed.
