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 CTS may not be able to detect a
vehicle ahead depending on the type
of vehicle ahead and its conditions,
the weather conditions, and the road
conditions. Additionally, the system
might be unable to decelerate
sufficiently if a vehicle ahead applies
the brakes suddenly, another vehicle
cuts into the driving lane, or the
difference in vehicle speed between
your vehicle and the vehicle ahead is
larger, which could result in an
accident. Check the surrounding
conditions and always drive carefully
while keeping a safe distance from
vehicles ahead and on-coming
vehicles.

For the purposes of safety, switch the
CTS off when it is not being used.
Leaving the CTS turned on when it is
not in use is dangerous as it could
operate unexpectedly, resulting in an
accident.

Do not use the CTS under the
following conditions. Otherwise, it
may result in an accident.
¾General roads other than
expressways or highways (Driving
under these conditions using the CTS
is not possible.)
¾Roads with sharp curves and where
vehicle traffic is heavy with
insufficient space between vehicles,
or roads where frequent and
repetitive acceleration and
deceleration occur (Driving under
these conditions using the CTS is not
possible).¾When entering and exiting
interchanges, service areas, and
parking areas of expressways (If you
exit an expressway while headway
control is in use, the vehicle ahead
will no longer be tracked and your
vehicle may accelerate to the set
speed).
¾Slippery roads such as icy or
snow-covered roads (Tyres could
spin causing you to lose vehicle
control, or the stop hold control may
not operate.)
¾Long , descending slopes (to
maintain distance between vehicles,
the system automatically and
continuously applies the brakes
which could result in the loss of
brake power.)
¾Two-wheeled vehicles such as
motorcycles or bicycles are ahead.
¾(Automatic transmission vehicle)
Slopes with a steep gradient (The
vehicle ahead may not be detected
correctly, your vehicle may slip while
stopped by the stop hold control, or
it may accelerate suddenly after it
starts moving.)
¾Driving under bad weather
conditions (rain, fog , and snow).
¾The vehicle is driven on slippery
roads such as icy or snow -covered
roads and unpaved roads (Tyres
could spin causing you to lose
vehicle control, or the stop hold
control may not operate.)
¾Tyres of a different specified size are
used, such as a temporary spare tyre.
¾Tyres with insufficient tread are used.
¾The tyre pressures are not adjusted to
the
specified pressure.
¾The vehicle is being used to tow a
camper or boat trailer.
¾Tyre chains are used.
When Driving
i-ACTIVSENSE
4-149

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.
