CAUTION Radio equipment like this is governed
by laws in the United States.
Changes or modifications not expressly
approved by the party responsible
for compliance could void the user's
authority to operate the equipment.
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 weak. 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 (for vehicles with
a type A instrument cluster (page
4-26 ), messages are displayed 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.
