2017 MAZDA MX5 MIATA high beam

4 –78 When Driving
i-ACTIVSENSE To Operate the SystemThe High Beam Control System (HBC)
operates to switch the headlights
automatically between high and low
beams after the ignition is switched ON
and the headlight switch is in the AUTO
and high beam position.
The High Beam Control System (HBC)
determines that it is dark based on the
brightness of the surrounding area. At the
same time, the High Beam Control System
(HBC) indicator light (green) in the
instrument cluster illuminates.
NOTE 
When the vehicle speed is about 30
km/h (19 mph) or more, the headlights
automatically switch to high beams
when there are no vehicles ahead or
approaching in the opposite direction.
When the vehicle speed is less than
about 20 km/h (12 mph), the High Beam
Control System (HBC) switches the
headlights to low beams. 
The low beams may not switch to high
beams when cornering. 
Operation of the High Beam Control
System (HBC) function can be disabled.
Refer to Personalization Features on
page 9-9 . Manual Switching Switching to low beams
Shift the lever to the low beam position.
The High Beam Control System (HBC)
indicator light (green) turns off.
Switching to high beams
Turn the headlight switch to the

position.
The High Beam Control System (HBC)
indicator light (green) turns off and the

is illuminated.

*Some models.Forward Sensing Camera (FSC) *
Your vehicle is equipped with a Forward Sensing Camera (FSC). The Forward Sensing
Camera (FSC) is positioned near the rearview mirror and used by the following systems.
High Beam Control System (HBC) 
Lane Departure Warning System (LDWS) Forward Sensing Camera (FSC)
The Forward Sensing Camera (FSC) determines the conditions ahea d of the vehicle while
traveling at night and detects traffic lanes. The distance in which the Forward Sensing
Camera (FSC) can detect objects varies depending on the surroun ding conditions.

CAUTION 
Do not apply accessories, stickers or film to the windshield near the Forward Sensing
Camera (FSC).
If the area in front of the Forward Sensing Camera (FSC) lens is obstructed, it will cause
the system to not operate correctly. Consequently, each system may not operate normally
which could lead to an unexpected accident. 
Do not disassemble or modify the Forward Sensing Camera (FSC).
Disassembly or modification of the Forward Sensing Camera (FSC) will cause a malfunction
or mistaken operation. Consequently, each system may not operate normally which could
lead to an unexpected accident. 
Heed the following cautions to assure the correct operation of the Forward Sensing Camera
(FSC). 
The direction of the Forward Sensing Camera (FSC) has been finely adjusted, therefore
do not change the installation position or remove the Forward Sensing Camera (FSC). 
Be careful not to scratch the Forward Sensing Camera (FSC) lens or allow it to get dirty. 
Do not remove the Forward Sensing Camera (FSC) cover. 
Do not place objects on the dashboard which reflect light. 
Always keep the windshield glass around the camera clean by removing dirt or fogging.
Use the windshield defroster to remove fogging on the windshield. 
Consult an Authorized Mazda Dealer regarding cleaning the interior side of the
windshield around the Forward Sensing Camera (FSC). 
Consult an Authorized Mazda Dealer before performing repairs around the Forward
Sensing Camera (FSC). 
The Forward Sensing Camera (FSC) is installed to the windshield. Consult an Authorized
Mazda Dealer for windshield repair and replacement. 
When performing repairs around the rearview mirror, consult an Authorized Mazda
Dealer. 
Do not hit or apply strong force to the Forward Sensing Camera (FSC) or the area around
it. If strong force is applied, stop using the Lane Departure Warning System (LDWS), and
the High Beam Control System (HBC) and consult an Authorized Mazda Dealer. 
The 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.

i-ACTIVSENSENOTE 
In the following cases, the Forward Sensing Camera (FSC) cannot detect target objects
correctly, and each system may be unable to operate normally. 
The height of the vehicle ahead is low. 
You drive your vehicle at the same speed as the vehicle ahead. 
Headlights are not turned on during the night or when going through a tunnel. 
In the following cases, the Forward Sensing Camera (FSC) may not be able to detect
target objects correctly. 
When driving next to walls with no patterning (including fences and longitudinally
striped walls). 
The taillights of the vehicle ahead are turned off. 
A vehicle is outside the illumination range of the headlights. 
The vehicle is making a sharp turn, or ascending or descending a steep slope. 
Entering or exiting a tunnel. 
Heavy luggage is loaded causing the vehicle to tilt. 
Strong light is shone at the front of the vehicle (back light or high-beam light from on-
coming vehicles). 
There are many light emitters on the vehicle ahead. 
When the vehicle ahead is not equipped with taillights or the taillights are turned off at
nighttime. 
The vehicle ahead has a special shape. For example, a vehicle towing a trailer house
or a boat, or a vehicle carrier carrying a vehicle with its front pointed rearward.

5 –15 Interior Features
Audio SystemFM characteristics
An FM broadcast range is usually about
40—50 km (25—30 miles) from the
source. Because of extra coding needed to
break the sound into two channels, stereo
FM has even less range than monaural
(non-stereo) FM. FM Station
40—50km
(25—30 miles)
Signals from an FM transmitter are similar
to beams of light because they do not
bend around corners, but they do reflect.
Unlike AM signals, FM signals cannot
travel beyond the horizon. Therefore, FM
stations cannot be received at the great
distances possible with AM reception.
AM wa veFM wa ve
FM wa ve
100—200 km (60—120 miles) Ionosphere
Atmospheric conditions can also affect
FM reception. High humidity will cause
poor reception. However, cloudy days may
provide better reception than clear days. Multipath noise
Since FM signals can be reflected by
obstructions, it is possible to receive both
the direct signal and the reflected signal
at the same time. This causes a slight
delay in reception and may be heard as a
broken sound or a distortion. This problem
may also be encountered when in close
proximity to the transmitter. Reflected wa ve
Direct
Flutter/Skip noise
Signals from an FM transmitter move in
straight lines and become weak in valleys
between tall buildings, mountains, and
other obstacles. When a vehicle passes
through such an area, the reception
conditions may change suddenly, resulting
in annoying noise.
