Overview of occupant safety

In this section, you will learn the most important facts about the restraint system components of the vehicle.

The restraint system consists of:

• seat belts
• child restraint systems
• LATCH-type (ISOFIX) child seat anchors Additional protection is provided by:

• SRS (Supplemental Restraint System)
• NECK-PRO head restraints/NECK-PRO luxury head restraints
• PRE-SAFE®
• Air bag system components with:

- PASSENGER AIR BAG OFF indicator lamp
- USA only: front-passenger seat with
Occupant Classification System (OCS)
- Canada only: front-passenger seat with BabySmart™ air bag deactivation system The different air bag systems work independently of each other. The protective functions of the system work in conjunction with each other. Not all air bags are deployed in an accident.

WARNING Modifications to or work improperly 
Modifications to or work improperly conducted on restraint system components or their wiring, as well as tampering with interconnected electronic systems, can lead to the restraint systems no longer functioning as intended.
Air bags or Emergency Tensioning Devices/belt buckle tensioners, for example, could deploy inadvertently or fail to deploy.
Therefore, never modify the restraint systems. Do not tamper with electronic components or their software.
