relatively low speed.
The warning tone sounds for up to five
minutes or until you fasten your seatbelt.
SWITCHING THE SEATBELT
REMINDER ON AND OFF WARNING: While the system
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

seatbelt reminder has been previously
disabled, it will be re-enabled during the use
of MyKey. See
MyKey ™ (page 98).

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
seatbelt three times at a moderate
speed, ending in the unbuckled state.
After Step 3, the seatbelt warning light
switches on.
4. When the seatbelt warning light is on, buckle then unbuckle the seatbelt.
After Step 4, the seatbelt warning light
flashes for confirmation.
This switches the feature off for that
seating position if it is currently on.
This switches the feature on for that

properly and are not damaged. Make sure
there are no nicks, tears or cuts. Replace if
necessary.
Check the following seatbelt assemblies
after a crash.
• Retractors.
• Buckles.
• Front seatbelt buckle assemblies.
