CAUTION
Heed the following precautions to assure correct operation of each system.
Do not adhere stickers (including transparent stickers) to the surface of the radiator
grille and front emblem in and around the radar sensor (front), and do not replace
the radiator grille and front emblem with any product that is not a genuine product
designed for use with the radar sensor (front).
The radar sensor (front) includes a function for detecting soiling of the radar sensor's
front surface and informing the driver, however, depending on the conditions, it may
require time to detect or it may not detect plastic shopping bags, ice or snow. If this
occurs, the system may not operate correctly, therefore always keep the radar sensor
(front) clean.
Do not install a grille guard.
If the front part of the vehicle has been damaged in a vehicle accident, the position of
the radar sensor (front) may have moved. Stop the system immediately and always
have the vehicle inspected at an Authorized Mazda Dealer.
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 modify the radar sensor (front).
For repairs, replacement or paint work around the radar sensor (front), consult an
Authorized Mazda Dealer.
Do not modify the suspension. If the suspension are modifi ed, the vehicle's posture
could change and the radar sensor (front) may not be able to correctly detect a vehicle
ahead or an obstruction.

When Driving
i-ACTIVSENSE
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 refl ect 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 refl ecting 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 specifi ed size,
manufacturer, brand, and tread pattern on all four wheels. In addition, do not use tires
with signifi cantly 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.
When driving on roads with little traffi c and few vehicles ahead or obstructions for
the radar sensor (front) to detect, “Front Radar Sensor Blocked” may be temporarily
displayed, however, this does not indicate a problem.

Tire Pressure Monitoring System
*Some models.
Tire Pressure Monitoring System *
The Tire Pressure Monitoring System (TPMS) monitors the air pressure of all four tires. If
the air pressure of one or more tires is too low, the system warns the driver by indicating the
tire pressure monitoring system warning light in the instrument cluster and operating a beep
sound. The system monitors the tire pressures indirectly using the data sent from the ABS
wheel speed sensors.
To allow the system to operate correctly, the system needs to be initialized with the specifi ed
tire pressure (value on the tire pressure label). Follow the procedure and perform the
initialization.
Refer to Tire Pressure Monitoring System Initialization on page 4-153 .
The warning light fl ashes when the system has a malfunction.
Refer to Warning Indication/Warning Lights on page 4-32 .

Parking Sensor System
*Some models.
Parking Sensor System *
The parking sensor system uses ultrasonic sensors to detect obstructions around the vehicle
while parking the vehicle in a garage or during parallel parking when the selector lever
is in reverse (R). The system is equipped with an assist device to notify the driver of the
approximate distance from the vehicle to the surrounding obstruction using a beep sound
and obstruction detection indication.
Rear corner sensor Rear sensor
WARNING
Do not rely completely on the parking sensor system and be sure to confi rm the safety
around your vehicle visually when driving:
This system can assist the driver in operating the vehicle in the backward directions while
parking. The detection ranges of the sensors are limited, therefore, driving the vehicle
while relying only on the system may cause an accident. Always confi rm the safety
around your vehicle visually when driving.
NOTE
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 the surrounding conditions, the detection range
of a sensor may narrow, or the sensors may not be able to detect obstructions.
