Keys
KeysWARNINGDo 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. Children may find these keys to
be an interesting toy to play with and
could cause the power windows or
other controls to operate, or even make
the vehicle move.
CAUTION 
Because the key (transmitter) uses
low-intensity radio waves, it may not
function correctly under the following
conditions: 
The key is carried with
communication devices such as
cellular phones. 
The key contacts or is covered by a
metal object. 
The key is near electronic devices such
as personal computers. 
Non-Mazda genuine electronic
equipment is installed in the vehicle. 
There is equipment which discharges
radio waves near the vehicle. 
The key (transmitter) may consume
battery power excessively if it receives
high-intensity radio waves. Do not place
the key near electronic devices such as
televisions or personal computers. 
To avoid damage to the key
(transmitter), DO NOT: 
Drop the key. 
Get the key wet. 
Disassemble the key. 
Expose the key to high temperatures
on places such as the dashboard or
hood, under direct sunlight. 
Expose the key to any kind of
magnetic field. 
Place heavy objects on the key. 
Put the key in an ultrasonic cleaner. 
Put any magnetized objects close to
the key.
A code number is stamped on the plate
attached to the key set; detach this plate
and store it in a safe place (not in the
vehicle) for use if you need to make a
replacement key (auxiliary key).
Also write down the code number and
keep it in a separate safe and convenient
place, but not in the vehicle.
If your key (auxiliary key) is lost, consult
your Authorized Mazda Dealer and have
your code number ready.

from ON to OFF, whether or not the
A/C is on or off, to cool the engine
compartment quickly. 
When the push button start is pressed
from ON to ACC or OFF, the KEY
indicator light (green) may flash for
approximately 30 seconds indicating
that the remaining battery power of the
key is low.
Replace with a new battery before the
key becomes unusable.
Refer to Key Battery Replacement on
page 6-38 . 
(Automatic transmission)
If the engine is turned off while the
selector lever is in a position other than
P, the ignition switches to ACC.
