i-ELOOP
*Some models.
i-ELOOP *
On conventional vehicles, the kinetic energy that is generated when the vehicle is
decelerated by applying the brakes or during engine braking ends up being discarded as
heat. By utilizing this discarded kinetic energy to generate electricity and use it to power the
vehicle's electrical devices and accessories such as the A/C and audio, fuel consumption can
be reduced. Mazda's system for generating electricity from this kinetic energy is called the
Regenerative Braking System (i-ELOOP).

i-ACTIVSENSE
i-ACTIVSENSE is a collective term covering a series of advanced safety and driver support
systems which make use of a Forward Sensing Camera (FSC) and radar sensors. These
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.

When Driving
i-ACTIVSENSE
CAUTION
Do not modify the suspension. If the vehicle height or the damping force of the
suspensions is changed, the LDWS may not operate correctly.

N O T E
 


y If your vehicle deviates from its traf¿ c lane, the LDWS operates (warning sound and
indicator light). Steer the vehicle adequately to drive the vehicle to the center of the lane.
 


y When the turn signal lever is operated for a lane change, the LDWS warning is
automatically canceled. The LDWS warning becomes operable when the turn signal lever
is returned and the system detects the white or yellow lines.
 


y If the steering wheel, accelerator pedal, or brake pedal is operated abruptly and the
vehicle moves close to a white or yellow line, the system determines that the driver is
making a lane change and the LDWS warning is automatically canceled.
 


y The LDWS may not operate during the period immediately after the vehicle has deviated
from its lane and the LDWS has operated, or the vehicle deviates from its lane repeatedly
within a short period of time.
 


y The LDWS does not operate if it does not detect the white or yellow lines of the traf¿ c
lane.

Auto cancel
Under the following conditions, the
LDWS is automatically canceled and
kept on stand-by, and the LDWS warning
light (amber) in the instrument cluster
illuminates.
 


y The system cannot detect white or
yellow lines.
 


y The vehicle speed is less than about 65
km/h (40 mph).
 


y The vehicle is making a sharp turn.



y The vehicle is making a turn at an
inadequate speed.
 


y The temperature inside the camera is
high or low.
 


y The windshield around the camera is
foggy.
 


y The windshield around the camera is
blocked by an obstruction, causing poor
forward visibility.

The lane indication (bordered line) is
indicated in the active driving display
(Type A instrument cluster
*1 ) or the multi
information display (Type B instrument
cluster
*1 ).
The LDWS is automatically enabled when
the condition changes and the system is
operable.

*1 To determine which instrument cluster
is equipped on your Mazda, Refer to
Meters and Gauges on page 4-11 .

Auto cancel of warning
Under the following conditions, the
LDWS determines that the driver is
making lane changes and the warning is
automatically canceled.
The LDWS is automatically enabled after
the operation.
 


y The steering wheel is operated abruptly.



y The brake pedal is depressed abruptly.



y The accelerator pedal is depressed
abruptly.
 


y A turn signal lever is operated (after the
turn signal lever is returned, the LDWS
warning may not operate for about 3
seconds which is the period of time
required to make a lane correction).

N O T E
 


y After about 5 seconds have elapsed
with the turn signal lever left operating,
the LDWS warning may operate if the
vehicle is close to a white or yellow line.
 


y The sensitivity of the warning
(sensitivity with which the system
determines the driver's intentional lane
change) can be changed.
  Refer to Personalization Features on
page 9-12 .

Canceling the System
To cancel the LDWS, press the LDWS
switch. The LDWS indicator light (Green/
Amber) in the instrument cluster turns off.
The lane indication displayed in the
active driving display (Type A instrument
cluster
*1 ) or the multi information display
(Type B instrument cluster *1 ) turns off.
*1 To determine which instrument cluster
is equipped on your Mazda, Refer to
Meters and Gauges on page 4-11 .

For the purposes of safety, switch the Mazda Radar Cruise Control (MRCC) system off
when it is not being used.

CAUTION
If the vehicle is towed or you are towing something, switch the Mazda Radar Cruise
Control (MRCC) system off to prevent an incorrect operation.

N O T E

y During 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.
 


y While the Mazda Radar Cruise Control (MRCC) system is in use, it does not cancel even
if the selector lever (automatic transaxle)/shift lever (manual transaxle) is operated and
any intended engine braking will not occur. If deceleration is required, lower the vehicle
speed setting or depress the brake pedal.
 


y The brake lights are illuminated while the Mazda Radar Cruise Control (MRCC)
automatic braking is operating.
 


y The Mazda Radar Cruise Control (MRCC) warning light (amber) turns on when the
system has a malfunction.
  Refer to Warning/Indicator Lights on page 4-20 .
Mazda Radar Cruise Control (MRCC) Display Indication
The setting status and operation conditions of the Mazda Radar Cruise Control (MRCC)
system are indicated in the active driving display.

Close Proximity Warning
If your vehicle rapidly closes in on the vehicle ahead because the vehicle applies the brakes
suddenly while you are traveling in headway control, the warning sound activates and
the brake warning is indicated in the display. Always verify the safety of the surrounding
area and depress the brake pedal while keeping a safer distance from the vehicle ahead.
Additionally, always keep a safer distance from the vehicles behind you.

CAUTION
 


¾ When driving off -road in areas where there is grass or forage, it is recommended that the
Smart City Brake Support (SCBS) system be turned off .




¾ Always use tires for all wheels that are of the specifi ed size, and the same manufacturer,
brand, and tread pattern. In addition, do not use tires with signifi cantly diff erent wear
patterns on the same vehicle as the Smart City Brake Support (SCBS) system may not
operate normally.
 


¾ The laser sensor (front) includes a function for detecting a soiled windshield and informing
the driver, however, depending on the conditions, it may not detect plastic shopping bags,
ice or snow on the windshield. In such cases, the system cannot accurately determine a
vehicle ahead and may not be able to operate normally. Always drive carefully and pay
attention to the road ahead.

N O T E
 


y The Smart City Brake Support (SCBS) system will not operate if the driver is deliberately
performing driving operations (accelerator pedal and steering wheel).
 


y The Smart City Brake Support (SCBS) system will operate under the following conditions. 



y The engine is running.



y The Smart City Brake Support (SCBS) warning light (amber) does not illuminate.



y The vehicle speed is between about 4 to 30 km/h (2 to 18 mph).



y The Smart City Brake Support (SCBS) system is not turned off.



y The DSC operation is not turned off using the DSC OFF switch.



y The DSC is not malfunctioning. 



y The Smart City Brake Support (SCBS) detects a vehicle ahead by emitting a near-infrared
laser beam and receiving the beam reÀ ected off the reÀ ector of the vehicle ahead, and
then using it for the measurement. Consequently, the Smart City Brake Support (SCBS)
may not operate under the following conditions:
 


y ReÀ ection of the laser is poor due to the shape of the vehicle ahead.



y The vehicle ahead is signi¿ cantly dirty.



y Under bad weather condition, such as rain, fog and snow.



y The window washer is being used or the windshield wipers are not used when it's
raining.
 


y The windshield is dirty.



y The steering wheel is turned completely left or right, or the vehicle is accelerated
rapidly and comes close to the vehicle ahead.
 


y Trucks with low loading platforms and vehicles with an extremely low or high pro¿ le.



y Vehicles with certain shapes such as a vehicle carrier.
