Distance & Speed Alert(DSA)
*
▼Distance & Speed Alert (DSA)
The DSA is a system which provides
advice for maintai
ning the appropriate
distance between vehicles and notifies the
driver of the recommended, safe distance
to maintain with a vehicle ahead. The
system measures the distance between
your vehicle and a vehicle ahead while the
vehicle speed is about 30 km/h (19 mph)
or faster. If the distance between your
vehicle and a vehicle ahead is close, the
system alerts the driver of a possible
collision using an indication on the
display.
WA R N I N G
Do not rely completely on the DSA.
The ability of the system to detect a vehicle
ahead is limited depending on the type of
vehicle ahead, weather conditions, or
traffic conditions. In addition, the system is
not for maintaining the distance between
your vehicle and a vehicle ahead. If you
neglect to operate the accelerator and
brake pedals correctly, it could lead to an
accident. Always check the safety of the
surrounding area and depress the brake
pedal or accelerator pedal while keeping a
safe distance from vehicles ahead or
on-coming vehicles.
Operation conditions
The DSA operates when the following
conditions are all met.
The ignition i s switched ON.
The DSA is turned on.
The shift lever (manual transmission
vehicle) or the selector lever (automatic
transmission vehicle) is in a position
other than R.
The vehicle speed is about 30 km/h (19
mph) or faster.
i-ACTIVSENSE status symbol
(warning/risk avoidance support system)
(green) is displayed.
NOTE
The objects which activate the system
are four-wheeled vehicles.
The DSA may also operate in the
presence of motorcycles and bicycles.
The DSA may not operate normally
when the speed of a vehicle ahead is too
slow.
The system does not operate with the
following objects.
Vehicles approaching in the opposite
direction.
Stationary objects (stopped vehicles,
obstructions)
The DSA can be set to inoperable.
(If only the DSA is turned off)
Refer to the Settings section in the
Mazda Connect Owner's Manual.
(If the DSA is turned off by operating
the i-ACTIVSENSE switch)
Refer to i-ACTIVSENSE Switch on
page 4-85.
When 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 DSA operable,
the system will be operable when the
ignition is switched ON the next time.

WA R N I N G
Always check the surrounding area visually
before actually putting the vehicle in
reverse:
The system is only designed to assist you in
checking for vehicles at the rear when
putting the vehicle in reverse. Due to
certain limitations with the operation of
this system, the Blind Spot Monitoring
(BSM) warning indicator lights may not
flash or it might be delayed even though a
vehicle is behind your vehicle. Always make
it your responsibility as a driver to check
the rear.
RCTA operation
1. The RCTA system operates when the shift lever (manual transmission) or the
selector lever (automatic transmission)

Traffic Jam Assist (TJA)*
▼Traffic Jam Assist (TJA)
The TJA is a system which consists of a
headway control fu
nction and steering
assist function for reducing driver fatigue
when driving in a traffic jam on
expressways or highways.
The 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 lan e 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.
WA R N I N G
Do not rely completely on TJA:
 The TJA 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.
 Set a vehicle speed within the speed limit
according to the road conditions and the
weather conditions.
The TJA 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.
 While the TJA 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.

For the purposes of safety, switch the TJA
off when it is not being used.

Do not use the TJA under the following
conditions. Otherwise, it may result in an
accident.
 General roads other than expressways or
highways (Driving under these
conditions using the TJA is not possible.)
 Roads with sharp curves and where
vehicle traffic is heavy with insufficient
space between vehicles. Roads where
frequent and repetitive acceleration and
deceleration occur (Driving under these
conditions using the TJA is not possible).
When Driving
i-ACTIVSENSE
*Some models.4-135
Mazda3_8HE9-EA-18K_Edition3 2018-11-21 14:31:58

When 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).
 Long, descending slopes (to maintain
distance between vehicles, the system
automatically and continuously applies
the brakes which could result in the loss
of brake power.)
 The vehicle ahead is traveling at an
extremely slow speed.
 Two-wheeled vehicles such as
motorcycles or bicycles are ahead.
 (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.)
 Driving under bad weather conditions
(rain, fog, and snow).
 The TJA cannot detect lane lines.
 Narrow roads resulting from road
construction or lane closures.
 The vehicle is driven on slippery roads
such as icy or snow -covered roads and
unpaved roads (Tires could spin causing
you to lose vehicle control, or the stop
hold control may not operate.)
 Tires of a
different
specified size are used,
such as a temporary spare tire.
 Tires with insufficient tread are used.
 The tire pressures are not adjusted to the
specified pressure.
 The vehicle is being used to tow a
camper or boat trailer.
 Tire chains are used.The vehicle is driven on roads with lane
lines other than white (yellow) lines, such
as an expressway.

(Automatic transmission vehicle)
Do not get out of the vehicle while the stop
hold control is operating.
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 TJA 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 TJA
can operate normally.
 Do not modify the vehicle's suspensions.
 Always use wheels of the
specified type
and size for the front and rear wheels.
Consult an Authorized Mazda Dealer for
tire replacement.
