Keyless Entry System
▼Keyless Entry System
This system uses the key buttons to
remotely lock and unlock the doors,
liftgate, and fuel-filler flap, and opens/
closes the liftgate.
The system can start the engine
without having to take the key out of
your purse or pocket.
Operating the theft-deterrent system is
also possible on theft-deterrent
system-equipped vehicles.

System malfunctions or warnings are
indicated by the following warning
lights or beeps.
Check the displayed message for more
information and, if necessary, have the
vehicle inspected at an expert repairer
(we recommend an Authorised Mazda
Repairer), according to the indication.

If you have a problem with the key,

If your key is lost or stolen, consult an
expert repairer (we recommend an
Authorised Mazda Repairer) as soon as
possible for a replacement and to
make the lost or stolen key inoperative.
CAUTION
Changes or modifications not expressly
approved by the party responsible for
compliance could void the user's
authority to operate the equipment.
NOTE
xThe keyless entry system operation
may vary due to local conditions.
xThe keyless entry system is fully
operational when the ignition is
switched off. The system does not
operate if the ignition is switched to
any position other than off.
xIf the key does not operate when
pressing a button or the operational
range becomes too small, the battery
may be weak. To install a new
battery, refer to Key Battery
Replacement (page 6-39).
xBattery life is about 1 year. Replace
the battery with a new one if the
messages are displayed in the
instrument cluster. Replacing the
battery about once a year is
recommended because the KEY
warning indication may not display
depending on the rate of battery
depletion.
xAdditional keys can be obtained at
an Authorised Mazda Repairer. Up
to 6 keys can be used with the
keyless functions per vehicle. Bring
all keys to an Authorised Mazda
Repairer when additional keys are
required.

▼Lights-On Reminder
If the ignition is switched OFF with the
exterior lights turned on and the
driver’s door is opened, a sound is
activated.
Operate the headlight switch to turn
off the exterior lights.
NOTE
xWhen the ignition is switched to
ACC, the “Ignition Not Switched
Off
(STOP) Warning Beep” (page 7-67)
overrides the lights-on reminder.
xA personalised function is available
to change the sound volume for the
lights-on reminder.
Refer to the Settings section in the
Mazda Connect Owner's Manual.
▼Seat Belt Warning Beep
Front seat
If the vehicle speed exceeds about 20
km/h (12 mph) with the driver or front
passenger's seat belt unfastened, a
warning beep sounds continuously. If
the seat belt remains unfastened, the
beep sound stops once and then
continues for about 90 seconds. The
beep stops after the driver or front
passenger's seat belt is fastened.
NOTE
xPlacing 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.
xTo 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.
xWhen a small child sits on the front
passenger seat, it is possible that the
warning beep will not operate.
Rear seat
The warning beep only sounds if a seat
belt is unfastened after being fastened.
▼Ignition Not Switched Off (STOP)
