The parking sensor detection range has limitations. For example, obstructions closing in from
the side and objects short in height may not be detected. Always confirm the safety around
the vehicle visually when driving.
For details, refer to the parking sensor obstruction detection indication and warning sound.
Refer to Parking Sensor System on page 4-237.
NOTE
The setting can be changed so that the projected vehicle path lines are not displayed.

around the vehicle visually when driving.
For details, refer to the parking sensor obstruction detection indication and warning sound.
Refer to Parking Sensor System on page 4-237.
¾Do not turn the steering wheel any more until the vehicle has passed the obstruction, even
if the obstruction is not visible on the side view image. If the steering wheel is turned even
more, the vehicle may contact the obstruction if it is turned sharply.
NOTE
xBecause there might be a difference between the image displayed on the screen and the
actual conditions, always check the safety of the surrounding area using the mirrors and
directly with your eyes when driving.
xEven though the object displayed on the screen, such as a road curb or a division line of a
parking space, and the vehicle parallel guide lines appear parallel, they may not actually
be parallel.

around the vehicle visually when driving.
For details, refer to the parking sensor obstruction detection indication and warning sound.
Refer to Parking Sensor System on page 4-237.
NOTE
xBecause there might be a difference between the image displayed on the screen, such as
indicated in the following, and the actual conditions when parking, always check the
safety at the rear of the vehicle and the surrounding area directly with your eyes.
xEven though the back end of the parking space (or garage) displayed on the screen and
distance guide lines appear parallel, they may not actually be parallel.
xWhen parking in a space with a division line on only one side of the parking space, even
though the division line and the vehicle width guide line appear parallel, they may not
actually be parallel.
xThe following shows an example of vehicle parking with the steering wheel turned to the
right while backing up the vehicle. When backing into a parking space from the opposite
direction, the steering operation is reversed.

¾Do not hit or apply strong force to the Forward Sensing Camera (FSC) or the area around
it. If the Forward Sensing Camera (FSC) is severely hit or if there are cracks or damage
caused by
flying gravel or debris in the area around it, stop using the following systems
and consult an expert repairer (we recommend an Authorised Mazda Repairer).

¾The direction in which the Forward Sensing Camera (FSC) is pointed has been finely
adjusted. Do not change the installation position of the Forward Sensing Camera (FSC) or
remove it. Otherwise, it could result in damage or malfunction.
¾Always use tyres for all wheels that are of the
specified size, and the same manufacturer,
brand, and tread pattern. In addition, do not use tyres with significantly different wear
patterns on the same vehicle as the system may not operate normally.
¾The Forward Sensing Camera (FSC) includes a function for detecting a soiled windscreen
and informing the driver, however, depending on the conditions, it may not detect plastic
shopping bags, ice or snow on the windscreen. In such cases, the system cannot accurately
determine a vehicle ahead and may not be able to operate normally. Always drive carefully
and pay attention to the road ahead.
NOTE
xIn the following cases, the Forward Sensing Camera (FSC) cannot detect target objects
correctly, and each system may be unable to operate normally.
xThe height of the vehicle ahead is low.
xYou drive your vehicle at the same speed as the vehicle ahead.
xHeadlights are not turned on during the night or when going through a tunnel.
xIn the following cases, the Forward Sensing Camera (FSC) may not be able to detect
target objects correctly.
xUnder bad weather condition, such as rain, fog and snow.
xThe window washer is being used or the windscreen wipers are not used when it's
raining.
xIce, fog, snow, frost, rainfall, dirt, or foreign matter such as a plastic bag is stuck on the
windscreen.
