NOTE
The keyless entry system operation may
vary due to local conditions. The keyless entry system is fully
operational (door/fuel-filler lid lock/
unlock) when the ignition is switched
off. The system does not operate if the
ignition is switched to any position
other than off. If the key does not operate when
pressing a button or the operational
range becomes too small, the battery
may be dead. To install a new battery,
refer to Key Battery Replacement (page
6-38). Battery life is about one year. Replace
the battery with a new one if the KEY
indicator light (green) flashes in the
instrument cluster. Replacing the battery
about once a year is recommended
because the KEY warning light/
indicator light may not illuminate or
flash depending on the rate of battery
depletion.
Additional keys can be obtained at
an Authorized Mazda Dealer. Up to
6 keys can be used with the keyless
functions per vehicle. Bring all keys
to an Authorized Mazda Dealer when
additional keys are required.

WARNING
Always take all children and pets with
you or leave a responsible person with
them:
Leaving a child or a pet unattended in
a parked vehicle is dangerous. In hot
weather, temperatures inside a vehicle
can become high enough to cause
brain damage or even death.
Do not leave the key in your vehicle with
children and keep them in a place where
your children will not find or play with
them:
Leaving children in a vehicle with the
key is dangerous. This could result in
someone being badly injured or even
killed.
Keep both doors locked when driving:
Unlocked doors in a moving vehicle
are dangerous. Passengers can fall out
if a door is accidentally opened and
can more easily be thrown out in an
accident.
Always close both the windows and
convertible top, lock the doors and take
the key with you when leaving your
vehicle unattended:
Leaving your vehicle unlocked is
dangerous as children could lock
themselves in a hot vehicle, which
could result in death. Also, a vehicle left
unlocked becomes an easy target for
thieves and intruders.
After closing the doors, always verify
that they are securely closed:
Doors not securely closed are
dangerous, if the vehicle is driven with
a door not securely closed, the door
could open unexpectedly resulting in
an accident.
Always confirm the safety around the
vehicle before opening a door:
Suddenly opening a door is dangerous.
A passing vehicle or a pedestrian could
be hit and cause an accident.
CAUTION
Always confirm the conditions around
the vehicle before opening/closing the
doors and use caution during strong
winds or when parked on an incline. Not
being aware of the conditions around
the vehicle is dangerous because fingers
could get caught in the door or a passing
pedestrian could be hit, resulting in an
unexpected accident or injury. If the power window does not go up or
down automatically because the battery
is dead, slowly open/close the power
window while pressing the glass inward.
Otherwise, the power window may
contact the convertible top and the door
cannot be opened/closed resulting in
damage to the window.
