Important safety notes
WARNING
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 (ETDs), for example, could deploy inadvertently or fail to deploy in accidents although the deceleration threshold for air bag deployment is exceeded. Therefore, never modify the restraint systems. Do not tamper with electronic components or their software.
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
• Air bag system components with:
- The 
indicator lamp
- 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 always deployed in an accident.
Observe the additional information on infants and children traveling with you in the vehicle and restraint systems for infants and children .
