CAUTION
Do not install any accessories within the detection ranges of the sensors. It may
affect the
system operation.
 Depending on the type of obstruction and th e surrounding conditions, the detection range
of a sensor may narrow, or the sensors may not be able to detect obstructions.
NOTE
The system may not operate norma lly under the following conditions:
Mud, ice, or snow is adhering to the sensor area (Returns to normal operation when
removed).
The sensor area is frozen (Returns to normal operation when the ice is thawed).
The sensor is covered by a hand.
The sensor is excessively shocked.
The vehicle is excessively tilted.
Under extremely hot or cold weather conditions.
The vehicle is driven on bumps, inclines, gravel, grating, or grass covered roads.
Anything which generates ultrasonic waves such as another vehicle's horn, the engine
sound of a motorcycle, the air brake sound of a large-sized vehicle, or another vehicle's
sensors approaches the vehicle.
The vehicle is driven in heavy rain or in road conditions causing water-splash.
A commercially-available fender pole or an antenna for a radio transmitter is installed
to the vehicle.
The vehicle is moving towards a tall or square curbstone, or a steep grade.
An obstruction is too close to the sensor.
The vehicle is moving towards an uneven wall or stairs.
There are multiple obstructions.
The vehicle is driven in a place with low ceilings.
Obstructions under the bumper cannot be detected. Obstructions which are lower than the
sensor or thin may not be detected even though they were detected once.
The following types of obstructions may not be detected:
Thin objects such as wire, rope or poles
Things which absorb sonic waves easily such as cotton or snow
Angular shaped objects
Very tall objects, and those which are wide at the top
Small, short objects
Always have the system inspected at an Aut horized Mazda Dealer if any shock is applied
to the bumpers, even in a minor accident. If the sensors are deviated, they cannot detect
obstructions.

Operating Tips
▼Operating Tips
Operate the climate control system with
the engine running.
To prevent the battery from being
discharged, do not leave the fan control
switch on for a long
period of time with
the ignition switched ON when the
engine is not running.
Clear all obstructions such as leaves,
snow and ice from the hood and the air
inlet in the cowl grille to improve the
system efficiency.
Use the climate control system to defog
the windows and dehumidify the air.
The recirculate mode should be used
when driving through tunnels or while
in a traffic jam, or when you would like
to shut off outside air for quick cooling
of the interior.
Use the outside air position for
ventilation or windshield defrosting.
If the vehicle has been parked in direct
sunlight during hot weather, open the
windows to let warm air escape, then
run the climate control system.
(With A/C switch)
Run the air conditioner about 10
minutes at least once a month to keep
internal parts lubricated.
Have the air conditioner checked before
the weather gets hot. Lack of refrigerant
may make the air conditioner less
efficient.
The refrigerant specifications are
indicated on a label attached to the
inside of the engine compartment. If the
wrong type of refrigerant is used, it
could result in a ser ious malfunction of
the air conditioner. Consult a
professional, government certified
repairer for the inspection or repair
because a special device is required for
the air conditi oner maintenance.
For details, consult an Authorized
Mazda Dealer.
