Seat Belt Pretensioners; Buckling And Unbuckling Seat Belts - Volvo XC 90 Owner's Manual

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.

Buckling and unbuckling seat belts

Seat belts should be used by all occupants in
the vehicle when it is in motion.
Buckling a seat belt
1. Pull the belt out slowly. It should not be twis-
ted or turned.
NOTE
Each seat belt is equipped with a seat belt
retractor that will lock up in the following sit-
uations:
•
if the belt is pulled out rapidly
•
during braking and acceleration
•
if the vehicle is leaning excessively
•
when driving in turns
•
if the Automatic Locking Retractor/Emer-
gency Locking Retractor (ALR/ELR) is
activated (each seat belt (except for the
driver's belt) is equipped with the
ALR/ELR function, which is designed to
help keep the seat belt taut. ALR/ELR
activates if the seat belt is pulled out as far
as possible. If this is done, a sound from
the seat belt retractor will be audible,
which is normal, and the seat belt will be
pulled taut and locked in place. This func-
tion is automatically disabled when the
seat belt is unbuckled and fully retracted).
