CAUTION
 Heed the following cautions so that
the radar sensors can function
normally.
 Do not modify the suspensions.
 Always use tires of the specified
size and the same manufacturer,
brand, and tread pattern on all 4
wheels. In addition, do not use
tires with significantly different
wear patterns or tire pressures on
the same vehicle (including
temporary spare tire).
Do not spray highly pressurized
water against the radar sensors or
rub them strongly.
 Do not apply stickers on parts near
the radar sensors.
 If foreign matter adheres to parts
near the radar sensors, remove it
and switch the vehicle power OFF.

and emblem with anything other
than genuine products.
 If strong force is applied to parts near
the radar sensors, the direction of
the radar sensor may become
deviated and each system may not
operate normally. Stop each system
immediately and have the vehicle
inspected by an Authorized Mazda
Dealer.

detect objects varies depending on
the surrounding conditions.
The Forward Sensing Camera (FSC)
may not be able to detect target
objects correctly, and the HBC may
not operate normally.
Refer to Forward Sensing Camera
(FSC) on page 5-127.
Using the HBC
Make sure that the light switch is in the
