Seatbelt tensioner
The car is fitted with standard seatbelt tension-
ers and electric seatbelt tensioners that can ten-
sion the seatbelts in critical situations and colli-
sions.
Standard seatbelt tensioner
All the seatbelts are equipped with a standard
seatbelt tensioner.
The seatbelt tensioner tensions the seatbelt in
the event of a collision with sufficient force in
order to more effectively restrain the occupant.
Electric seatbelt tensioner
The driver and front passenger seatbelts are
equipped with an electric seatbelt tensioner.
The seatbelt tensioners work together and can
be activated together with the driver support sys-
tems City Safety and Rear Collision Warning. In
critical situations, such as panic braking, driving
off the road (e.g. the car rolls into a ditch, lifts off
the ground or hits something in the terrain), skid-
ding, or risk of collision, the seatbelt can be ten-
sioned by the seatbelt tensioner's electric motor.
The electric seatbelt tensioner helps to adjust the
occupant to a better position, reducing the risk of
striking the car's interior and improving the effect
of safety systems, such as the car's airbags.
When the critical situation has come to an end,
the seatbelt and the electric seatbelt preten-
sioner are restored automatically, but they can
also be restored manually.
IMPORTANT
If the passenger airbag is deactivated, the
electric seatbelt tensioner on the passenger
side will also be deactivated.
WARNING
Never modify or repair the seatbelts yourself.
Volvo recommends that an authorised Volvo
workshop should be contacted.
If the seatbelt has been subjected to a major
load, such as in conjunction with a collision,
the entire seatbelt must be replaced. Some of
the seatbelt's protective properties may have
been lost even if the seatbelt does not appear
damaged. The seatbelt must also be replaced
if it shows signs of wear or damage. The new
seatbelt must be type-approved and designed
for installation at the same location as the
replaced seatbelt.
