Safety Belt Pretensioners
This vehicle has safety belt
pretensioners for front outboard
occupants. Although the safety
belt pretensioners cannot be seen,
they are part of the safety belt
assembly. They can help tighten the
safety 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. And, if your
vehicle has side impact airbags,
safety belt pretensioners can help
tighten the safety belts in a side
crash or a rollover event.
Pretensioners work only once.
If the pretensioners activate in a
crash, they will need to be replaced,
and probably other new parts for
the vehicle's safety belt system.
See Replacing Safety Belt System
Parts After a Crash on page 3‑28.
Rear Safety Belt Comfort
Guides
This vehicle may have rear shoulder
belt comfort guides. If not, they
are available through your dealer.
The guides may provide added
safety belt comfort for older children
who have outgrown booster seats
and for some adults. When installed
and properly adjusted, the comfort
guide positions the belt away from
the neck and head.
Here is how to install a comfort
guide to the shoulder belt:
1. Remove the guide from its
storage clip on the interior body.
2. Place the guide over the belt
and insert the two edges of the
belt into the slots of the guide.
