Seating and Safety Restraints
WARNING: While the design allows you to deactivate your
Belt-Minder , this system is designed to improve your chances of
being safely belted and surviving an accident. We recommend you
leave the Belt-Minder system activated for yourself and others who
may use the vehicle. To reduce the risk of injury, do not
deactivate/activate the Belt-Minder feature while driving the vehicle.
1. Turn the ignition switch to the on position. DO NOT START THE
ENGINE.
2. Wait until the safety belt warning light turns off. (Approximately one
minute)
• Step 3 must be completed within 30 seconds after the safety belt
warning light turns off.
3. For the seating position being disabled, buckle then unbuckle the
safety belt three times, ending in the unbuckled state.
• After Step 3, the restraint system warning light (airbag light) will be
turned on for three seconds.
4. Within approximately seven seconds of the light turning off, buckle
then unbuckle the safety belt.
• This will disable the Belt-Minder feature for that seating position if it
is currently enabled. As confirmation, the restraint system warning
light will flash four times per second for three seconds.
• This will enable the Belt-Minder feature for that seating position if it
is currently disabled. As confirmation, the restraint system warning
light will flash four times per second for three seconds, followed by
three seconds with the light off, then followed by the restraint system
warning light flashing four times per second for three seconds again.
Safety belt extension assembly
If the safety belt is too short when fully extended, there is an 8 inch
(20 cm) safety belt extension assembly that can be added (part number
611C22). This assembly can be obtained 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.
WARNING: Do not use extensions to change the fit of the
shoulder belt across the torso.
