2018 MAZDA MODEL CX-9 battery replacement

Keys
WA R N I N G
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. 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.
NOTE
The driver must carry the key to ensure the
system functions properly.

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/liftgate 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 4-31),
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.

Operational Range
The system operates only when the driver
is in the vehicle or within operational
range while the key is being carried.
NOTE
When the battery power is low, or in
places where there are high-intensity radio
waves or noise, the operational range may
become narrower or the system may not
operate. For determining battery
replacement, Refer to Keyless Entry
System on page 3-3.

▼Emergency Operati
on for Starting
the Engine
If the KEY warning light (red) illuminates,
or the push button start indicator light
(amber) flashes, this could indicate that
the engine may not s tart using the usual
starting method (for vehicles with a type A
instrument cluster (page 4-31), messages
are displayed in the instrument cluster).
Have your vehicle inspected at an
Authorized Mazda Dealer as soon as
possible. If this occurs, the engine can be
force-started. Press and hold the push
button start until the engine starts. Other
procedures necessary for starting the
engine such as having the key in the cabin,
and depressing the brake pedal are
required.
Turning the Engine Off
WA R N I N G
Do not stop the engine while the vehicle is
moving:
Stopping the engine while the vehicle is
moving for any reason other than in an
emergency is dangerous. Stopping the
engine while the vehicle is moving will
result in reduced braking ability due to the
loss of power braking, which could cause
an accident and serious injury.
1. Stop the vehicle completely.
2. Shift the selector lever to the P position and set the parking brake.
3. Press the push button start to turn off the engine. The ignition position is off.
CAUTION
When leaving the vehicle, make sure the
push button start is off.
NOTE
•The cooling fan in the engine
compartment could turn on for a few
minutes after the ignition is switched
from ON to OFF, whether or not the A/C
is on or off, to cool the engine
compartment quickly.
•If the system detects that the remaining
battery power of the key is low when the
ignition is switched from ON to ACC or
OFF, the following is indicated.
Replace with a new battery before the
key becomes unusable.
Refer to Key Battery Replacement on
page 6-38.

Do not use the front bumper to push other vehicles or obstructions such as when pulling
out of a parking space. Otherwise, the radar sensor (front) could be hit and its position
deviated.
 Do not remove, disassemble, or mo dify the radar sensor (front).
 For repairs, replacement or paint work ar ound the radar sensor (front), consult an
Authorized Mazda Dealer.
 Do not modify the suspension. If the suspensi on are modified, the vehicle's posture could
change and the radar sensor (front) may not be able to correctly detect a vehicle ahead or
an obstruction.
NOTE
•Under the following conditions, the radar sensor (front) may not be able to detect vehicles
ahead or obstructions correctly and each system may not operate normally.
•The rear surface of a vehicle ahead does not reflect radio waves effectively, such as an
unloaded trailer or an automobile with a loading platform covered by a soft top,
vehicles with a hard plastic tailgate, and round-shaped vehicles.
•Vehicles ahead with low vehicle height and thus less area for reflecting radio waves.
•Visibility is reduced due to a vehicle ahead casting off water, snow, or sand from its tires
and onto your windshield.
•The luggage compartment is loaded with heavy objects or the rear passenger seats are
occupied.
•Ice, snow, or soiling is on the front surface of the front emblem.
•During inclement weather such as rain, snow, or sand storms.
•When driving near facilities or objects emitting strong radio waves.
•Under the following conditions, the radar sensor (front) may not be able to detect vehicles
ahead or obstructions.
•The beginning and end of a curve.
•Roads with continuous curves.
•Narrow lane roads due to road construction or lane closures.
•The vehicle ahead enters the radar sensor's blind spot.
•The vehicle ahead is running abnormally due to accident or vehicle damage.
•Roads with repeated up and down slopes
•Driving on poor roads or unpaved roads.
•The distance between your vehicle and the vehicle ahead is extremely short.
•A vehicle suddenly comes close such as by cutting into the lane.
•To prevent incorrect operation of the system, use tires of the same specified size,
manufacturer, brand, and tread pattern on all four wheels. In addition, do not use tires
with significantly different wear patterns or tire pressures on the same vehicle (Including
the temporary spare tire).
•If the battery power is weak, the system may not operate correctly.
