Safety Belt Extension Assembly
WARNING: Do not use extensions to change the fit of the
shoulder belt across the torso.
If the safety belt is too short when fully extended, you can obtain a
safety belt extension assembly from an authorized dealer.
Use only extensions manufactured by the same supplier as the safety
belt. Manufacturer identification is located at the end of the webbing on
the label. Also, use the safety belt extension only if the safety belt is too
short for you when fully extended.
SAFETY BELT HEIGHT ADJUSTMENT
WARNING: Position the safety belt height adjusters so that the
belt rests across the middle of your shoulder. Failure to adjust
the safety belt properly could reduce the effectiveness of the safety belt
and increase the risk of injury in a crash.
Adjust the height of the shoulder belt so the belt rests across the middle
of your shoulder.
To adjust the shoulder belt height:
1. Pull on the center button and
slide the height adjuster up or
down.
2. Release the button and pull down
on the height adjuster to make sure
it is locked in place.
