Refer to Supplemental Restraint System (SRS) Health and Safety Precautions information.

The supplemental restraint system (SRS) provides additional protection for occupants in certain vehicle accident conditions.

The supplemental restraint system (SRS) comprises the following sub-systems:

Driver and passenger front air bag system.
Roll over protection system (convertible only).
Driver and passenger side air bag system.
Safety belt pretension system.
Occupant detection system or classification system.

The supplemental restraint system (SRS) features selective activation of the air bags and safety belt pretensioners, and two stage driver and passenger air bags. The restraints control module (RCM) monitors internal and external sensors and activates the required safety belt pretensioners, air bags and roll over protection hoops (convertible only) if the sensors detect an impact or roll over above preset limits.

The roll over protection system comprises two spring loaded hoops located behind the rear seat. The hoops incorporate a pin to break the rear window glass as the hoop is released. The hoops are released by a pyrotechnic device when the restraints control module (RCM) detects a roll over condition.
