Automatic Seat Belt
Tightening System
The vehicle may have the
Automatic Seat Belt
Tightening System.
Each time the front seat belts
are buckled while the vehicle is
in P (Park) or D (Drive) and the
engine is running or in Auto
Stop (if equipped), the system
may activate to tighten the
seat belts.
The system also activates
during emergency braking
and/or sudden driving
maneuvers and releases when
driving conditions return to
normal.
The system will not activate if
the Traction Control/
Electronic Stability Control
system is not functioning
properly. See Traction
Control/Electronic Stability
Control 0 271. If there is a
problem with the Automatic
Seat Belt Tightening System, a
message displays on the
Driver Information Center
(DIC). If a system unavailable
message displays repeatedly
or if a service message
displays, see your dealer.
Other seat belt functions are
not affected by the Automatic
Seat Belt Tightening System.
Seat Belt Pretensioners
This vehicle has seat belt
pretensioners for the front
outboard occupants. Although
the seat belt pretensioners
cannot be seen, they are part
of the seat belt assembly.
They can help tighten the seat
belts during the early stages
of a moderate to severe
frontal, near frontal, or rear
crash if the threshold
conditions for pretensioner
activation are met. Seat belt
pretensioners can also help
tighten the seat belts in a side
crash or a rollover event.
Pretensioners work only once.
If the pretensioners activate in
a crash, the pretensioners and
probably other parts of the
vehicle s seat belt system will
need to be replaced. See
Replacing Seat Belt System
Parts after a Crash 0 68.
Do not sit on the outboard
seat belt while entering or
exiting the vehicle or at any
time while sitting in the seat.
Sitting on the seat belt can
damage the webbing and
hardware.
