2021 MAZDA MODEL CX-3 brake light

Traction Control System(TCS)
The Traction Cont rol System (TCS)
enhances traction and safety by controlling
engine torque and braking. When the TCS
detects driving wheel slippage, it lowers
engine torque and operates the brakes to
prevent loss of traction.

This means that on a slick surface, the
engine adjusts automatically to provide
optimum power to the drive wheels,
limiting wheel spin and loss of traction.

The warning light turns on when the
system has a malfunction.
Refer to Contact Authorized Mazda
Dealer and Have Vehicle Inspected on
page 7-29.
WA R N I N G
Do not rely on the Traction Control System
(TCS) as a substitute for safe driving:
The Traction Control System (TCS) 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.
Use snow tires or tire chains and drive at
reduced speeds when roads are covered
with ice and/or snow:
Driving without proper traction devices on
snow and/or ice-covered roads is
dangerous. The Traction Control System
(TCS) alone cannot provide adequate
traction and you could still have an
accident.
NOTE
To turn off the TCS, press the TCS OFF
switch (page 4-67).
▼ 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.
NOTE
In addition to the indicator light
flashing, a slight lugging sound will
come from the engine. This indicates
that the TCS/DSC is operating properly.
On slippery surfaces, such as fresh
snow, it will be impossible to achieve
high rpm when the TCS is on.

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 4-65) and TCS (page
4-66).

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 7-29.

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 windshield around the camera is
blocked by an obstruction, causing poor
forward visibility.
The LDWS is enabled automatically when
the operation conditions are met, and the
LDWS warning light turns off.
Auto cancel warning
When the following operations are
performed, the LDWS de termines that the
driver intends to make a lane change and
the LDWS warning is canceled
automatically. The LDWS is enabled
automatically after the driver performs the
operation.
The steering wheel is operated abruptly.
The brake pedal is depressed abruptly.
The accelerator pedal is depressed
abruptly.
The turn signal lever is operated (after
the turn signal lever is returned, the
LDWS may not operate for about 3
seconds which is the period of time
required to make a lane correction).
NOTE
After about 30 seconds have elapsed with
the turn signal lever left operating, the
LDWS warning may operate if the vehicle
is close to a white or yellow line.
▼ Canceling the System
Press the LDWS OFF switch to cancel the
LDWS. The LDWS OFF indicator light
turns on.

Distance Recognition Support System (DRSS)*
The DRSS measures the distance between your vehicle and a vehicle ahead using a radar
sensor (front) while the vehicle speed is ab out 30 km/h (19 mph) or faster, and if your
vehicle approaches a vehicle ahead more closely than what is appropriate for maintaining
distance between the vehicles according to the vehicle speed, a notification in the active
driving display is indicated to advise you to keep a safe distance from the vehicle ahead.
WARNING
Do not rely completely on the DRSS and always drive carefully:
The ability to detect a vehicle ahead is limited depending on th e type of vehicle ahead, the
weather conditions, and the traffic conditions. Therefore, if the accelerator and brake pedals
are not operated correctly it could lead to an accident. Always verify the safety of the
surrounding area and depress the brake pedal or accelerator pedal while keeping a safer
distance from vehicles ahead or on-coming vehicles.
NOTE
The DRSS operates when all of the following conditions are met:
The ignition is switched ON.
The DRSS is on.
The selector lever is in a position other than reverse (R).
The vehicle speed is 30 km/h or faster (19 mph or faster).
The objects which activate the system are 4-wheeled vehicles.
The DRSS may also operate in the presence of motorcycles and bicycles.
The DRSS may not operate normally under the following conditions:
The Dynamic Stability Control (DSC) has a malfunction.

During headway control travel, the system accelerates and decelerates your vehicle in
conjunction with the speed of the vehicle ahead. However, if it is necessary to accelerate
for a lane change or if the vehicle ahead brakes suddenly causing you to close in on the
vehicle rapidly, accelerate using the accelerator pedal or decelerate using the brake
pedal depending on the conditions.
While the MRCC with Stop & Go function system is in use, it does not cancel even if the
selector lever is operated and any intended engine braking does not occur. If deceleration
is required, lower the set speed or depress the brake pedal.
The sound of the automatic brakes operating may be heard, however, it does not indicate
a problem.
The brake lights turn on while the MRCC with Stop & Go function automatic braking is
