allows you to deactivate it, this system
is designed to improve your chances of
being safely belted and surviving an
accident. We recommend you leave the
system activated for yourself and others
who may use the vehicle.
Note:The driver and front passenger
warnings switch on and off independently.
When you perform this procedure for one
seating position, do not buckle the other
position as this will terminate the process.
Read Steps 1 - 4 thoroughly before
proceeding with the programming
procedure.Before following the procedure, make sure
that:
• The parking brake is set.
• The transmission is in park (P) or
neutral (N).
• The ignition is off.
• The driver and front passenger safety
belts are unbuckled.
1. Switch the ignition on. Do not start the
vehicle.
2. Wait until the safety belt warning light
turns off (about one minute). After
Step 2, wait an additional 5 seconds
before proceeding with Step 3. Once
you start Step 3, you must complete
the procedure within 30 seconds.
3. For the seating position you are
switching off, buckle then unbuckle the
safety belt three times at a moderate
speed, ending in the unbuckled state.
After Step 3, the safety belt warning
light turns on.

detects an approaching vehicle’s
headlamps or tail lamps, or street lighting
ahead, the system turns off high beams
before they can distract other road users.
