warning light MAZDA MODEL CX-3 2019 (in English) Service Manual

Dynamic Stability Control(DSC)
The Dynamic Stability Control (DSC)
automatically controls braking and engine
torque in conjunction with systems such as
ABS and TCS to help control side slip
when driving on slippery surfaces, or
during sudden or evasive maneuvering,
enhancing vehicle safety.

Refer to ABS (page 4-67) and TCS (page
4-68).

DSC operation is possible at speeds
greater than 20 km/h (12 mph).

The warning light turns on when the
system has a malfunction.
Refer to Contact Authorized Mazda
Dealer and Have Vehicle Inspected on
page 7-30.
WA R N I N G
Do not rely on the Dynamic Stability
Control as a substitute for safe driving:
The Dynamic Stability Control (DSC)
cannot compensate for unsafe and reckless
driving, excessive speed, tailgating
(following another vehicle too closely), and
hydroplaning (reduced tire friction and
road contact because of water on the road
surface). You can still have an accident.
CAUTION
 The DSC may not operate correctly
unless the following are observed:
 Use tires of the correct size
specified for
your Mazda on all four wheels.
 Use tires of the same manufacturer,
brand and tread pattern on all four
wheels.
 Do not mix worn tires.
 The DSC may not operate correctly when
tire chains are used or a temporary spare
tire is installed because the tire diameter
changes.
â–¼ TCS/DSC Indicator Light
This indicator light stays on for a few
seconds when the ignition is switched ON.
If the TCS or DSC is operating, the
indicator light flashes.

If the light stays on, the TCS, DSC or the
brake assist system may have a
malfunction and they may not operate
correctly. Take your vehicle to an
Authorized Mazda Dealer.

CX-3_8GR7-EA-18B_Edition1 2017-12-20 16:18:14

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 resp onsible for assuring lane changes and other
maneuvers. Always pay attention to the directi on in which the vehicle is traveling and the
vehicle’s surroundings.
CAUTION
Do not modify the suspension. If the vehicle he ight or the damping force of the suspensions is
changed, the LDWS may not operate correctly.
NOTE
•If your vehicle deviates from its traffic 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 det ect 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 or on the rear seat and 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 visi ble 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 be cause 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 b y notifying the driver of 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 notifie s the driver by turning on the
BSM warning indicator light and displaying the vehicle detectio n screen (vehicles with
active driving display).
If the turn signal lever is operated to signal a turn in the di rection in which the BSM
warning indicator light is illuminated while the approaching ve hicle is detected, the BSM
notifies the driver of possible danger by turning on the BSM wa rning indicator light, and by
activating the warning sound and the warning screen indicator d isplay (vehicles with active
