Signal Warning Action to be taken
Seat Belt
Warning Light
With warning light for front passenger's seat
The seat belt warning light illuminates if the driver or front passenger\
's seat is occupied and the
seat belt is not fastened with the ignition switched ON.
Without warning light for front passenger's seat
The seat belt warning light illuminates if the driver's seat is occupied\
and the seat belt is not
fastened with the ignition switched ON.
Seat belt reminder
NOTE
Consult an Authorized Mazda Dealer to deactivate or restore the belt reminder. Though the belt
reminder can be deactivated, doing so will defeat the purpose of the syst\
em to warn the driver and
the front passenger in the event that their seat belts are not fastened. For the safety of the driver
and front passenger, Mazda recommends not deactivating the belt reminder.
Front seat
If the vehicle is driven with the driver or front passenger's seat belt \
unfastened, the seat belt
warning light illuminates and a warning beep sounds.
NOTE
Some models do not have the seat belt reminder function for the front passenger's seat.
If the driver or front passenger's seat belt is unfastened (only when t\
he front passenger seat is
occupied) and the vehicle is driven at a speed faster than about 20 km/\
h (12 mph), the warning light
will fl ash and a beep sound will be heard. After a short time, the warning light stops fl ashing, but
remains illuminated, and the beep sound stops.
Until a seat belt is fastened or a given period of time has elapsed, the\
beep sound will not stop even
if the vehicle speed falls below 20 km/h (12 mph).
NOTE
yThe warning light fl ashes and a beep sound will be heard for about 6 seconds if the driver's seat
belt is not fastened when the ignition is switched ON.
y If a driver or front passenger's seat belt is unfastened after the beep sound turns off (\
warning light remains illuminated), and the vehicle speed exceeds 20 km/h (12 mph), \
the warning light fl ashes
and beep sound activates again.
yPlacing heavy items on the front passenger seat may cause the front passenger seat belt warning function to operate depending on the weight of the item.
yTo allow the front passenger seat weight sensor to function properly, do not place and sit on an additional seat cushion on the front passenger seat. The sensor may not function properly
because the additional seat cushion could cause sensor interference.
y When a small child sits on the front passenger seat, it is possible that the warning light will not operate.
Door-Ajar Warning Light The light turns on if any door is not closed
securely.
Close the door securely.

If Trouble Arises
Warning/Indicator Lights and Warning Sounds
Seat Belt Warning Beep
If the driver's seat belt is not fastened
when the ignition is switched ON, a beep
sound will be heard for about 6 seconds. If
the driver or the front passenger's seat belt
is not fastened and the vehicle is driven
at a speed faster than about 20 km/h (12
mph), a beep sound will be heard again for
a specifi ed period of time.
NOTE
 y Some models do not have the seat
belt warning function for the front
passenger's seat.
 y Placing heavy items on the front
passenger seat may cause the front
passenger seat belt warning function to
operate depending on the weight of the
item.
 y To allow the front passenger seat
weight sensor to function properly, do
not place and sit on an additional seat
cushion on the front passenger seat.
The sensor may not function properly
because the additional seat cushion
could cause sensor interference.
 y When a small child sits on the front
passenger seat, it is possible that the
warning beep will not operate.
Ignition Not Switched Off (STOP) Warning Beep
If the driver's door is opened while
the ignition is switched to ACC, a
continuous beep sound will be heard to
notify the driver that the ignition has not
been switched off (STOP). Left in this
condition, the keyless entry system will
not operate, the car cannot be locked, and
the battery power will be depleted.
Key Removed from Vehicle Warning Beep
A beep sound will be heard 6 times and
the KEY warning light (red) will fl ash
continuously if the ignition has not been
switched off, all the doors are closed, and
the key is removed from the vehicle. This
is to notify the driver that the key has been
removed from the vehicle and the ignition
has not been switched off.
NOTE
Because the key utilizes low-intensity
radio waves, the Key Removed From
Vehicle Warning may activate if the key is
carried together with a metal object or it
is placed in a poor signal reception area.
Request Switch Inoperable Warning Beep (With the advanced
keyless function)
If the request switch is pressed with a door
open or ajar or the ignition has not been
switched off while the key is being carried,
a beep will be heard for about 2 seconds
to indicate that the doors and the liftgate/
trunk lid cannot be locked.
Key Left-in-luggage Compartment Warning Beep (With the advanced
keyless function)
If the key is left in the trunk with all doors
locked and the trunk lid closed, a beep
sound is heard for about 10 seconds to
remind the driver the key has been left in
the trunk. If this happens, open the trunk
lid by pressing the electric trunk lid opener
and remove the key. A key removed from
the trunk may not function because its
functions may have been temporarily
suspended. To restore the key function,
perform the applicable procedure (page
3-8 ).
