engine MAZDA MODEL CX-30 2019 Owners Manual (in English)

xDuring 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.
xWhile 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.
xWhile braking by the MRCC with
Stop & Go function control is
operating , you might hear an
operation sound, however, this does
not indicate a problem.
xThe brake lights turn on while
braking by the MRCC with Stop &
Go function control is operating,
however, they may not turn on while
the vehicle is on a down slope at the
set vehicle speed or travelling at a
constant speed and following a
vehicle ahead.
xStop the headway control function to
switch the system to the cruise
control function.
Refer to the Settings section in the
Mazda Connect Owner's Manual.

Cruising & Traffic Support
(CTS)
*
▼Cruising & Traffic Support (CTS)
The CTS is a system which consists of a
headway control function and a
steering assist function for reducing
driver fatigue during traffic jams when
driving on expressways or highways.
This system performs headway control
to maintain a constant distance
between your vehicle and a vehicle
ahead at a preset vehicle speed
without you having to use the
accelerator or brake pedal. Even
further, with the steering assist
function, when vehicle lane lines are
detected, the function assists the driver
in keeping the vehicle within the lane
lines. If lane lines are not detected, the
function provides the driver driving
assistance in keeping the vehicle along
the motion path with the vehicle
ahead.
WARNING
Do not rely completely on CTS:
¾The CTS is not an automated driving
system. In addition, the functions
have limitations. Do not rely
completely on the system and always
stay on course using the steering
wheel.
¾Set a vehicle speed within the speed
limit according to the road
conditions and the weather
conditions.
When Driving
i-ACTIVSENSE
4-148*Some models.

¾The vehicle is driven on roads with
lane lines other than white (yellow)
lines, such as an expressway.

Do not get out of the vehicle while
the stop hold control is operating.
(Automatic transmission vehicle)
Getting out of the vehicle while the
stop hold control is operating is
dangerous as the vehicle may move
unexpectedly and result in an accident.
Before getting out of the vehicle,
switch the CTS off, apply the parking
brake, and then shift the selector lever
to the P position.

CAUTION
Turn the system off when the vehicle is
running on a chassis roller.
Heed the following cautions so that
the CTS can operate normally.
¾Turn the system off when the vehicle
is running on a chassis roller.
¾Do not modify the vehicle's
suspensions.
¾Always use wheels of the specified
size for the front and rear wheels.
Consult an expert repairer (we
recommend an Authorised Mazda
Repairer) for tyre replacement.

NOTE
xThe headway control does not detect
the following as physical objects.
xVehicles approaching in the
opposite direction
xPedestriansxStationary objects (stopped
vehicles, obstructions)
xIf a vehicle ahead is travelling at an
extremely low speed, the system may
not detect it correctly.
xIf there is a structure on the road or
an object (such as a monorail) at a
low height off the ground in front of
the vehicle, the system may operate.
Therefore, do not use the CTS.
xDo not use the CTS under conditions
in which close proximity warnings
are frequently activated.
xIf it is necessary to accelerate for a
lane change or 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.
xWhile the CTS is in use, any intended
engine braking does not occur even
if you shift the shift lever (manual
transmission) or the selector lever
(automatic transmission). If
deceleration is required, lower the
vehicle speed setting or depress the
brake pedal.
xWhile braking by the CTS control is
operating , you might hear an
operation sound, however, this does
not indicate a problem.
xThe brake lights turn on while
braking by the CTS control is
operating, however, they may not
turn on while the vehicle is on a
down slope at the set vehicle speed
or travelling at a constant speed and
following a vehicle ahead.
xUnder the following conditions, the
CTS may not be able to detect white
(yellow) lines or vehicles ahead
correctly and the CTS may not
operate normally.
xThe forward sensing camera (FSC)
cannot recognise the area in front
of the vehicle due to soiling or fog.
