xWhite (yellow) lane lines on both sides are detected and you are driving near the
centre of the lane, or your vehicle detects a vehicle ahead.
xThe steering wheel is not turned sharply.xThe direction indicator lever is not operated.xThe headway control function is operating.x(Manual transmission vehicle)
The vehicle speed is about 30 km/h (19 mph) or faster.
NOTE
The steering assist function operates so that the vehicle remains near the centre of
the driving lane, however, depending on conditions such as the road curvature, road
slope and undulations, and vehicle speed, the function might not be able to keep
the vehicle near the centre of the driving lane.
Setting method
1. CANCEL switch
2. RES switch
3. CTS switch

1. Press the CTS switch.
The CTS standby indication (white) turns on. In addition, the CTS display
indication is displayed on the multi-information display at the same time.
2. Adjust the vehicle speed to the desired setting using the accelerator pedal and
press the RES switch up (SET+) or down (SET-) to start headway control.
When Driving

4-155

The set speed is indicated on the display. At the same time, the CTS standby
indication (white) changes to the CTS set indication (green).
3. The headway control is operable when all of the conditions for it to operate are
met, or the steering assist function is operable when all of the conditions for it to
operate are met.
NOTE
xIf a vehicle ahead is detected while travelling at a constant speed, the
vehicle-ahead indication is displayed and headway control is performed.
Additionally, when a vehicle ahead is no longer detected, the vehicle-ahead
indication turns off and the system switches back to travel at constant speed.
xHeadway control is not possible if the vehicle ahead is driving faster than your
vehicle's set speed. Adjust the system to the desired vehicle speed using the
accelerator pedal.
xWhen the ignition is switched OFF, the system status before it was turned off is
maintained. For example, if the ignition is switched OFF with the CTS operable,
the CTS remains operational the next time the ignition is switched ON.
xWhen the CTS is operating, the Lane-keep Assist System (LAS), Distance & Speed
Alert (DSA), and Smart Brake Support (SBS) also turns on automatically.
xWhen the CTS switch is pressed while the Mazda Radar Cruise Control (MRCC) or
the Mazda Radar Cruise Control with Stop & Go function (MRCC with Stop & Go
function) system is operating, the CTS operates. In addition, when the MRCC
switch is pressed while the CTS is operating, the Mazda Radar Cruise Control
(MRCC) or the Mazda Radar Cruise Control with Stop & Go function (MRCC with
Stop & Go function) system operates.

Changing the set vehicle speed
(To accelerate/decelerate using the RES switch)
When the RES switch is pressed up (SET+), the vehicle accelerates and when the RES
switch is pressed down
(SET-), it decelerates.
xPress and release immediately: 1 km/h (1 mph)xPress and hold: 10 km/h (5 mph)
(To increase speed using accelerator pedal)
Depress the accelerator pedal and press the RES switch up (SET+) or down (SET-) at
the desired speed. If the switch is not operated, the system returns to the set speed
after you release your foot from the accelerator pedal.

NOTE
xThe warnings and brake control do not operate while depressing the accelerator
pedal.
xThe lowest possible speed which can be set on the CTS is 30 km/h (19 mph).x(European models)
When switching to a passing lane and operating the direction indicator, the system
provides more acceleration automatically if it determines that more acceleration is
required. Drive while being careful of the road ahead because you could approach
the vehicle ahead too closely.
x(Automatic transmission vehicle)
The vehicle speed setting can be changed by operating the RES switch during stop
hold control.

Changing the distance between vehicles during headway control
The distance-between-vehicles can be set to 4 levels; Long, medium, short, and
extremely short distance.
The distance-between-vehicles is set to a shorter distance by pressing the CANCEL
switch down. The distance-between-vehicles is set to a longer distance by pressing
the CANCEL switch up.

engine damage could occur.
xIf the gears are not shifted down
even though the shift-down request
indication is displayed, the CTS
might be automatically cancelled or
engine stalling could occur.
▼Stop Hold Control (Automatic
Transmission)
While in headway control using the
CTS, your vehicle will stop when a
vehicle ahead stops. When the vehicle
is stopped and the stop hold control
operates, the CTS indicator light turns
on.
NOTE
xEven if the CTS is temporarily
cancelled during stop hold control,
the vehicle is held in its stopped
position.
xThe parking brake is automatically
applied and the vehicle is held in its
stopped position when 10 minutes
or longer have passed since the stop
hold control operated. When this
occurs, the CTS is temporarily
cancelled.
xIf the i-stop operation conditions are
met during stop hold control, the
engine stops even though the brake
pedal is not depressed.
Refer to i-stop on page 4-11.
xThe brake lights turn on during stop
hold control.

To resume driving
After the vehicle ahead starts moving
while your vehicle is stopped under
stop hold control, press the RES switch
or depress the accelerator pedal to
cancel the stop hold control and start
driving.
NOTE
xWhen you resume driving by pressing
the RES switch, your vehicle does not
start moving until the distance
between your vehicle and the vehicle
ahead lengthens to the
specified
distance or farther.
xThe engine restarts automatically
when any of the actions to resume
driving are performed while i-stop is
operating.
xIf the CTS is temporarily cancelled
during stop hold control, you cannot
resume driving by pressing the RES
switch when there are no vehicles in
front of your vehicle. Depress the
accelerator pedal and resume driving
the vehicle.
When Driving
i-ACTIVSENSE

xIf the vehicle ahead starts moving
within 3 seconds after your vehicle is
stopped by the stop hold control,
headway control will continue even if
you do not resume driving your
vehicle, such as by depressing the
accelerator pedal.

Vehicle departure information
If you do not resume driving within a
few seconds after the vehicle ahead
starts moving during stop hold control,
the multi-information display
vehicle-ahead indication flashes to
urge the driver to resume driving. If you
do not resume driving after the
indicator light
flashes, a sound is
activated to urge you to resume
driving.
Lane-keep Assist System
(LAS)
*
▼Lane-keep Assist System (LAS)
The LAS provides steering assistance to
help the driver stay within the vehicle
lane if the vehicle might be deviating.
The forward sensing camera (FSC)
detects the white lines (yellow lines) of
the vehicle lane in which the vehicle is
travelling and if the system determines
that the vehicle may deviate from its
lane, it operates the electric power
steering to assist the driver’s steering
operation. The system also alerts the
driver by displaying an alert on the
multi-information display and the
active driving display. Use the system
when you drive the vehicle on roads
with white (yellow) lines such as
expressways and highways.
1. Forward sensing camera (FSC)
WARNING
Do not rely completely on the LAS:
¾The LAS is not an automated driving
system. In addition, the system is not
designed to compensate for a
driver’s lack of caution, and
over-reliance on the system could
lead to an accident.
