Mazda intelligent Drive
Select (Mi-Drive) (FWD)
*
▼ Mazda intelligent Drive Select
(Mi-Drive)
Mi-Drive is a system to switch the
vehicle's drive mode. When the sport
mode is selected, vehicle's response
against accelerator operation is
enhanced. This provides additional
quick acceleration which may be
needed to safely make maneuvers such
as lane changes, merging onto
freeways, or passing other vehicles.
CAUTION
Do not use the sport mode when
driving on slippery roads such as wet
or snow-covered roads. It may cause
tire slipping.
NOTE
When the sport mode is selected,
driving at higher engine speeds
increases and it may increase fuel
consumption. Mazda recommends
that you cancel the sport mode on
normal driving.
Drive mode cannot be switched in
the following conditions:
ABS/TCS/DSC is operatingThe Mazda Radar Cruise Control
with Stop & Go function (MRCC
with Stop & Go function) System is
operating.
Traffic Jam Assist (TJA) is operating.Steering wheel is being operated
abruptly

i-ACTIVSENSE*
▼i-ACTIVSENSE
i-ACTIVSENSE is a collective term
covering a series of advanced safety
and driver support systems which
make use of cameras and sensors. The
systems consist of active safety and
pre-crash safety systems.
These systems are designed to assist
the driver in safer driving by reducing
the load on the driver and helping to
avert collisions or reduce their severity.
However, because each system has its
limitations, always drive carefully and
do not rely solely on the systems.
▼Active Safety Technology
Active Safety Technology supports safer
driving by helping the driver to
recognize potential hazards and avert
accidents.

Blind Spot Monitoring(BSM)
*
▼Blind Spot Monitoring (BSM)
The BSM is designed to assist the driver
in checking the area to the rear of the
vehicle on both sides during lane
changes by notifying the driver of the
presence of vehicles approaching from
the rear in an adjacent lane.
BSM operation
The BSM detects vehicles approaching
from the rear while traveling in the
forward direction at a speed of 10
km/h (6.3 mph) or faster and notifies
the driver by turning on the BSM
warning indicator light and displaying
the vehicle detection screen.
If the turn signal lever is operated to
signal a turn in the direction in which
the BSM warning indicator light is
illuminated while the approaching
vehicle is detected, the BSM
notifies
the driver of possible danger flashing
on the BSM warning indicator light,
and by activating the warning sound
and the warning screen indicator
display.
The detection area on this system
covers the driving lanes on both sides
of the vehicle and from the rear part of
the front doors to about 50 m (164 ft)
behind the vehicle.
1. Your vehicle
2. Detection areas
WARNING
Always check the surrounding area
visually before making an actual lane
change:
The system is only designed to assist
you in checking for vehicles at your rear
when making a lane change. Due to
certain limitations with the operation
of this system, the BSM warning
indicator light, the warning sound and
the warning screen indicator display
may not activate or they might be
delayed even though a vehicle is in an
adjacent driving lane. Always make it
your responsibility as a driver to check
the rear.
NOTE
The BSM will operate when all of the
following conditions are met:
The ignition is switched ON.The i-ACTIVSENSE warning
indication/warning light in the
instrument cluster is turned off.
The vehicle speed is about 10
km/h (6.3 mph) or faster.
The BSM will not operate under the
following circumstances.
The vehicle speed falls below
about 10 km/h (6.3 mph) even
though the i-ACTIVSENSE warning
indication/warning light is turned off.
The selector lever is shifted to
reverse (R) and the vehicle is
reversing.
The turning radius is small (making
a sharp turn, turning at
intersections).

Traffic Jam Assist (TJA)*
▼Tra ffi c
Jam Assist (TJA)
The TJA 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 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.

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

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,
or roads where frequent and
repetitive acceleration and
deceleration occur (Driving under
these conditions using the TJA is not
possible).

The vehicle is shaken after hitting a
road bump.
There are various road markings or
division lines (lane markings) of
various shapes near an
intersection.
The area in front of the camera is
soiled or an object that obstructs
the field of view is installed.
Exhaust gas from the vehicle in
front, sand, snow, and water vapor
rising from manholes and grating ,
and water splashed into the air.
The surroundings are dark such as
during the early evening or early
morning.
A vehicle ahead with a certain
taillight shape.
A vehicle ahead veers off course
from your vehicle's line of travel.
A vehicle ahead is driving
erratically.
The vehicle is driven on roads with
tight curves.

Headway control function
If a vehicle ahead is detected while
traveling at a constant speed, the
vehicle-ahead indication is displayed
and headway control is performed.

Steering assist function
When 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.
NOTE
Steering assist limit warning
If the steering assi st function cannot
keep the vehicle within the lane lines
while the steering assist function is
operating, a warning sound is activated
and a warning is displayed on the
multi-information display to urge the
driver to operate the steering wheel.
