Understanding Pre Safe Mode In Mercedes

Pre Safe Mode is a safety feature in Mercedes vehicles that aims to prevent collisions by detecting irregularities such as swerving or skidding which are typically associated with the beginning of a collision or rollover.

In such cases, it is recommended to reset the system by pressing and holding the Pre Safe button for several seconds. If the warning lights or messages persist, it is advised to seek professional help from a mechanic or refer to the vehicle’s owner manual for further guidance on how to resolve the issue.

If these sensors become dirty or require adjustment, it can result in the “PRESAFE® Functions Limited” message being displayed on the vehicle’s information panel. In such cases, it is recommended to have the sensors cleaned or adjusted by a mechanic to restore the full functionality of the Pre Safe Mode system. It’s worth noting that the Pre Safe Mode system can be reset by using a Mercedes star diagnostic tool to resynchronize all seat positions of the driver and ensure proper sensor calibration.
