Hyundai Equus: Pre-tensioner seat belt - Seat belts - Safety features of your vehicle - Hyundai Equus 2009-2023 Owners ManualHyundai Equus: Pre-tensioner seat belt

Your vehicle is equipped with driver's and front passenger's pre-tensioner seat

Your vehicle is equipped with driver's and front passenger's pre-tensioner seat belts. The purpose of the pretensioner is to make sure that the seat belts fit tightly against the occupant's body in certain frontal collisions.

The pre-tensioner seat belts may be activated in crashes where the frontal collision is severe enough.


For your safety, be sure that the belt webbing is not loose or twisted and always sit properly on your seat.

When the vehicle stops suddenly, or if the occupant tries to lean forward too quickly, the seat belt retractor will lock into position. In certain frontal collisions, the pre-tensioner will activate and pull the seat belt into tighter contact against the occupant's body.

If the system senses excessive tension on the driver or passenger's seat belt when the pre-tensioner activates, the load limiter inside the pretensioner will release some of the pressure on the affected seat belt.


Do not put anything near the buckle. Placing objects near the buckle can adversely affect the buckle pre-tensioner and may increase the risk of personal injury in the event of a collision.

The seat belt pre-tensioner system consists mainly of the following components.

To obtain maximum benefit from a pre-tensioner seat belt: 1. The seat belt must be worn correctly and adjusted to the proper position. Please read and follow all of the important information and precautions about your vehicle’s occupant safety features – including seat belts and air bags – that are provided in this manual.
2. Be sure you and your passengers always wear seat belts properly.


  • Both the driver's and front passenger's pre-tensioner seat belts may be activated in certain frontal or side collisions or rollovers. The pre-tensioners will not be activated if the seat belts are not being worn at the time of the collision.

  • When the pre-tensioner seat belts are activated, a loud noise may be heard and fine dust, which may appear to be smoke, may be visible in the passenger compartment. These are normal operating conditions and are not hazardous.

  • Although it is non-toxic, the fine dust may cause skin irritation and should not be breathed for prolonged periods. Wash all exposed skin areas thoroughly after an accident in which the pre-tensioner seat belts were activated.


The sensor that activates the SRS air bag is connected with the pretensioner seat belt, and the SRS airbag warning light for approximately 6 seconds after the ignition switch has been turned to the ON on the instrument panel will illuminate
for approximately 6 seconds after the ignition switch has been turned to the ON position, and then it should turn off.


If the pre-tensioner seat belt is not working properly, the warning light will illuminate even if there is no malfunction of the SRS air bag. If the SRS air bag warning light does not illuminate when the ignition switch is turned ON, or if it remains illuminated after illuminating for approximately 6 seconds, or if it illuminates while the vehicle is being driven, have an authorized EQUUS dealer inspect the pre-tensioner seat belt and SRS air bag system as soon as possible.


  • Pre-tensioners are designed to operate only one time. After activation, pre-tensioner seat belts must be replaced. All seat belts, of any type, should always be replaced after they have been worn during a collision.
  • The pre-tensioner seat belt assembly mechanisms become hot during activation. Do not touch the pre-tensioner seat belt assemblies for several minutes after they have been activated.

  • Do not attempt to inspect or replace the pre-tensioner seat belts yourself. This must be done by an authorized EQUUS dealer.

  • Do not strike the pre-tensioner seat belt assemblies.

  • Do not attempt to service or repair the pre-tensioner seat belt system in any manner.

  • Improper handling of the pretensioner seat belt assemblies, and failure to heed the warnings not to strike, modify, inspect, replace, service or repair the pre-tensioner seat belt assemblies may lead to improper operation or inadvertent activation and serious injury.

  • Always wear the seat belts when driving or riding in a motor vehicle.

  • If the vehicle or pre-tensioner seat belt must be discarded, contact an authorized EQUUS dealer.
