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.
Belt-Minder activation and deactivation procedure
Read Steps 1 - 5 thoroughly before proceeding with the
deactivation/activation programming procedure.
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. Buckle then unbuckle the safety belt three times at a moderate speed,
ending with the safety belt in the unbuckled state.
• After Step 3 is complete, the safety belt warning light will be turned
on for three seconds.
• If Step 4 does not occur within 10 seconds at the end of Step 3,
Belt-Minder will automatically exit programming mode without
changing its enable status.
4. Within seven seconds of the light turning on, buckle then unbuckle the
safety belt.
• This will disable the Belt-Minder feature if it is currently enabled. As
confirmation, the safety belt warning light will flash four times per
second for three seconds.
• This will enable the Belt-Minder feature if it is currently disabled. As
confirmation, the safety belt warning light will flash four times per
second for three seconds, followed by three seconds with the light off,
then followed by the safety belt warning light flashing four times per
second for three seconds again.
After receiving confirmation, the deactivation/activation procedure is
complete.
