Convertible Rollover Bars are crucial safety features designed to protect occupants in the event of a rollover accident. In the 2011 BMW E93, this system is automatically activated under specific circumstances, deploying within fractions of a second to maintain headroom for passengers.
Understanding the Rollover Protection System in the BMW E93
The E93’s rollover protection system activates automatically in critical situations such as accidents, extreme tilting, or loss of ground contact. This system complements the reinforced windshield frame in providing essential protection. The system consists of two protection bars located behind the rear head restraints. These bars deploy upwards to create a survival space in case the vehicle rolls over.
It’s essential to keep the area around the rollover protection system clear of obstructions to ensure its proper deployment. In less severe accidents, the seatbelts, along with the safety belt tensioners and multi-phase airbags, provide primary protection. The rollover protection is a last resort safety measure for more serious incidents.
Resetting the Rollover Protection System
If the rollover protection system deploys without impact damage, it can be manually reset. This process doesn’t require any tools and can be performed by following these steps:
- Locate the locking lever on the deployed rollover bar. Push it to one side and hold it in that position.
- Apply downward pressure on the top of the protection bar, pushing it approximately halfway down.
- Release the locking lever.
- Continue pushing the protection bar down until it audibly clicks or snaps into its original, stowed position.
- Repeat steps 1 through 4 for the other protection bar.
While a manual reset is possible, it’s crucial to have the entire rollover protection system inspected by a qualified technician at a BMW center after any unexpected activation. This ensures the system’s long-term functionality and safety.
Important Considerations for Convertible Rollover Bars
Several crucial precautions should be observed regarding the convertible rollover bars:
- Hardtop Operation: Never operate the retractable hardtop while the rollover protection system is in the activated (deployed) position. This can cause damage to both systems.
- System Modifications: Avoid any modifications to the rollover protection system components or its wiring. Tampering with the system can lead to malfunctions or complete failure.
- Professional Servicing: All maintenance and repairs related to the rollover protection system should be handled exclusively by a BMW center. They possess the specialized knowledge and tools required to work on this complex safety system. Refer to your owner’s manual for recommended service intervals.
Regular maintenance, as outlined in the vehicle’s service schedule (refer to page 80 of the owner’s manual), is vital to ensure the reliable operation of the rollover protection system. This system is a critical safety component in the BMW E93 convertible, and its proper functioning can be lifesaving in a rollover accident. By understanding its operation and adhering to the recommended maintenance procedures, you can ensure optimal protection for yourself and your passengers.
