Additional Information About Your Seat Belts Seat Belt e-pretensioners If your vehicle gets too close to the vehicle ahead of it in your lane, the driver's e-pretensioner slightly retracts the seat belt to alert the driver of the approaching vehicle. If a collision with the vehicle in front of you is likely, the e-pretensioners on both front seats retract the seat belts with enough force to properly restrain you and your front passenger. After they activate, the epretensioners release the retracted seat belts. To get the full benefit of the epretensioners, you and your front passenger must sit normally in your seats and wear your seat belts properly (see page 16). The e-pretensioners do not activate when the vehicle stability assist (VSA) off indicator on the instrument panel is on. If the automatic seat belt tensioners are activated by a collision, both front seat belts and all related components must be replaced (see page 25). If only the e-pretensioners were activated, no components need to be replaced. In addition, the front passenger's epretensioner does not activate when the passenger's airbag is automatically turned off because the weight sensor detects a child in the front passenger's seat. On models with Collision Mitigation Braking System™ (CMBS™) For added safety, the front seat belts are equipped with e-pretensioners that work in combination with the collision mitigation braking system™ (CMBS™) (see page 457) and the brake pedal assist function (see page 454). 24 2011 MDX
