2023 MAZDA MX5 MIATA warning light

Lane Departure Warning System (LDWS)*
The LDWS notifies the driver that the vehicle may be deviating from its lane.
The system detects the white or yellow lines on the traffic lane using the Forward Sensing
Camera (FSC) and if it determines that the vehi cle may be deviating from its lane, it notifies
the driver by flashing the LDWS warning light and activating the LDWS warning beep, and
by the multi-information display (vehic les with multi-information display).
Use the LDWS when you drive the vehicle on roads with white or yellow lines.
Refer to Forward Sensing Camera on page 4-103.

The functions of the LDWS have limitations:
Always stay on course using the steering wheel and drive with care. The system is not
designed to compensate for a driver’s lack of caution and if you rely too much on the LDWS it
could lead to an accident. The driver is res ponsible for assuring lane changes and other
maneuvers. Always pay attention to the direction in which the vehicle is traveling and the
vehicle’s surroundings.
CAUTION
Do not modify the suspension. If the vehicle height or the damping force of the suspensions is
changed, the LDWS may not operate correctly.
NOTE
If your vehicle deviates from its traffi c lane, the LDWS operates (warning sound and
indicator light). Steer the vehicle adequately to drive the vehicle to the center of the lane.
When the turn signal lever is operated for a lane change, the LDWS warning is
automatically canceled. The LDWS warning becomes operable when the turn signal lever
is returned and the system detects the white or yellow lines.
If the steering wheel, accelerator pedal, or brake pedal is operated abruptly and the
vehicle moves close to a white or yellow line, the system determines that the driver is
making a lane change and the LDWS warning is automatically canceled.
The LDWS may not operate during the period immediately after the vehicle has deviated
from its lane and the LDWS has operated, or the vehicle deviates from its lane repeatedly
within a short period of time.
The LDWS does not operate if it does not dete ct the white or yellow lines of the traffic
lane.
Under the following conditions, the LDWS may not be able to detect white or yellow lines
correctly and the LDWS may not operate correctly.
If an object placed on the dashboard is reflected in the windshield and picked up by the
camera.
Heavy luggage is loaded in the luggage compartment the vehicle is inclined.
The tire pressures are not adjusted to the specified pressure.
When the vehicle is driven on the entry and exit to or from the rest area or tollgate of a
highway.
The white or yellow lines are less visible because of dirt or paint flaking.
The vehicle ahead is running near a white or yellow line and the line is less visible.
A white or yellow line is less visible because of bad weather (rain, fog, or snow).
The vehicle is driven on a temporary lane or section with a closed lane due to
construction.

Blind Spot Monitoring (BSM)*
The BSM is designed to assist the driver in checking the area to the rear of the vehicle on
both sides during lane changes by alerting the driver to the presence of vehicles approaching
from the rear in an adjacent lane.
The BSM detects vehicles approaching from the rear while traveling in the forward
direction at a speed of 10 km/h (6.3 mph) or faster and turns on the BSM warning lights
equipped on the door mirrors depending on the conditions. If the turn signal lever is
operated to signal a lane change in the direction in which the BSM warning light is
illuminated, the system warns the driver of a vehicle in the detection area by flashing the
BSM warning light and activating a beep sound.
The detection area on this system covers the driving lanes on both sides of the vehicle and
from the rear part of the doors to about 50 m (164 ft) behind the vehicle.
Detection areas Your vehicle
WA R N I N G
Always check the surrounding area visually before making an actual lane change:
The system is only designed to assist you in checking for vehicles at your rear when making a
lane change. Due to certain limitations with the operation of this system, the BSM warning
light may not flash or it might be delayed even th ough a vehicle is in an adjacent driving lane.
Always make it your responsibility as a driver to check the rear.
