Seat belt pretensioners
The vehicle's seat belts are equipped with stand-
ard and electric pretensioners that can help pull
the seat belts taut in a critical situation or a colli-
sion. Some or all of the pretensioners will be
triggered in certain types of collisions, depend-
ing on the direction and severity of the impact.
Reversible seat belt pretensioners
Reversible seat belt pretensioners is a system in
the front seats that pulls the seat belts slightly
taut prior to a collision. This function helps posi-
tion the front seat occupants to help improve the
effects of other safety systems, e.g., the airbag
system.
Seat belt pretensioners in collisions
The seat belts are equipped with standard pre-
tensioners that are triggered according to the
severity of a collision.
Seat belt pretensioners in critical
situations
In addition to the standard pretensioners, the
seat belts in the front seats are also equipped
with electric pretensioners.
The pretensioners interact and can be triggered
along with the City Safety and Rear Collision
Warning systems. In critical situations such as
sudden braking, evasive maneuvers, etc., the seat
belt can be pulled taut by the pretensioner's
electric motor.
The electric pretensioner positions the occupant
in the seat to help reduce the risk of striking the
interior of the passenger compartment and
improves the effect of other safety systems such
as the airbags.
Resetting the electric pretensioners
When a critical situation has passed, the seat belt
and the electric pretensioner are reset automati-
cally.
If the seat belt should remain taut:
1. Stop the vehicle safely.
2. Unbuckle the seat belt and rebuckle it.
> The seat belt and the electric preten-
sioner will be reset.
WARNING
•
Never repair the belt yourself; have this
work done by a trained and qualified
Volvo service technician only.
•
Any device used to induce slack into the
shoulder belt portion of the three-point
belt system will have a detrimental effect
on the amount of protection available to
you in the event of a collision.
•
The seat back should not be tilted too far
back. The shoulder belt must be taut in
order to function properly.
•
Do not use child safety seats or child
booster cushions/backrests in the front
passenger's seat. We also recommend
that children who have outgrown these
devices sit in the rear seat with the seat
belt properly fastened.
