i-ELOOP
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 bein\
g 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-ELOOP
i-ELOOP Indicator Light/Control Status Display
The driver is notifi ed of the i-ELOOP
power generating status and the vehicle
conditions by the i-ELOOP indicator light
and the control status display.
i-ELOOP Indicator Light
Illuminated (vehicle without type B
audio)
The light turns on during power
generation.
Flashing
If the engine is started after the vehicle has
not been driven for a long period of time,
the i-ELOOP indicator light may fl ash.
Leave the engine idling and wait until the
indicator light turns off.
NOTE
 y  The beep will sound if the vehicle is
driven while the i-ELOOP indicator
light is fl ashing. In addition, if you
turn the steering wheel while the light
is fl ashing, it will feel heavier than
normal, but this does not indicate an
abnormality. Stop the vehicle in a safe
location with the engine running and do
not attempt to turn the steering wheel.
The steering operation will return to
normal after the i-ELOOP indicator
light stops fl ashing.
 y(Vehicles with type B audio) A notifi cation is displayed in the center
display and the i-ELOOP indicator light
fl ashes at the same time.
 Refer to Warning Message Indicated on Display on page 7-33 .
Control status display (vehicles with
type B audio)
The i-ELOOP power generating status is
displayed in the center display.

When Driving
Drive Selection
Drive Selection *
Drive selection is a system to switch the vehicle's drive mode. When the sport mode
is selected, vehicle's response against accelerator operation is enhance\
d. This provides
additional quick acceleration which may be needed to safely make maneuve\
rs 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
 y When the sport mode is selected, driving at higher engine speeds increases and it may
increase fuel consumption. Mazda recommends to cancel the sport mode on normal
driving.
 y Drive mode cannot be switched in the following conditions:
 y ABS/TCS/DSC is operating y Steering wheel is being operated abruptly

Power Steering
Power Steering
 y Power steering is only operable when
the engine is running. If the engine is
off or if the power steering system is
inoperable, you can still steer, but it
requires more physical effort.
 If the steering feels stiffer than usual during normal driving or the steering
vibrates, consult an Authorized Mazda
Dealer.
 y The warning light notifi es the driver
of system abnormalities and operation
conditions.
 In addition, the buzzer may also activate depending on the system abnormality or
operation condition.
 Refer to Warning Lights on page 4-21 . Refer to Power Steering Warning Buzzer on page 7-38 .
CAUTION
Never hold the steering wheel to the
extreme left or right for more than 5
seconds with the engine running. This
could damage the power steering
system.

When Driving
Mazda Radar Cruise Control (MRCC)
 y In the following cases, the warnings may not activate even if your vehic\
le starts closing in
on the vehicle ahead.
 y You are driving at the same speed as the vehicle ahead. y Directly after the Mazda Radar Cruise Control (MRCC) system has been set. y When the accelerator pedal is depressed or directly after the accelerator pedal is
released.
 y Another vehicle cuts into the driving lane.
 y The following are not detected as physical objects.
 y Vehicles approaching in the opposite direction y Pedestrians y Stationary objects (stopped vehicles, obstructions)
 y If a vehicle ahead is traveling at an extremely low speed, the system may not detect it
correctly.
 y During headway control travel, do not set the system on two-wheeled vehicles such as
motorcycles and bicycles.
 y Do not use the Mazda Radar Cruise Control (MRCC) system under conditions in which
the close proximity warnings are frequently activated.
 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 trans\
axle) 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, however, they may not be illuminated while the vehicle is
on a down slope at the set vehicle speed or traveling at a constant spee\
d and following a
vehicle ahead.
 y The Mazda Radar Cruise Control (MRCC) warning light (amber) fl ashes when the system
has a malfunction.

How to Set the Distance Between
Vehicles During Headway Control
The distance between vehicles is set to a
shorter distance each time the
switch is
pressed. The distance between vehicles is
set to a longer distance by pressing the
switch. The distance-between-vehicles can
be set to 4 levels; Long, medium, short,
and extremely short distance.
Distance-between- vehicles guideline
(at 80 km/h (50 mph) vehicle speed) Indication on display
Long (about 50 m (164
ft))
Medium (about 40 m
(131 ft))
Short (about 30 m (98
ft))
Extremely short (about
25 m (82 ft))
NOTE
 y  The distance between vehicles differs
depending on the vehicle speed, and the
slower the vehicle speed, the shorter the
distance.
 y When the ignition is switched to ACC
or OFF and then the engine is started
again, the system automatically sets
the distance between vehicles to the
previous setting.
Changing the Set Vehicle Speed
Changing the set vehicle speed using the
SET
/ SET switch
Press the SET
switch to accelerate. Press
the SET
switch to decelerate. The set
vehicle speed changes as follows each
time the SET
/ SET switch is pressed.
Short press 1 km/h (1 mph)
Long press 10 km/h (5 mph)
NOTE
For example, the set vehicle speed is
changed by pressing the SET
/ SET
switch four times as follows:
The vehicle speed accelerates or
decelerates by 4 km/h (4 mph).
To accelerate using the accelerator
pedal
Depress the accelerator pedal and press
and release the SET
or SET switch at
the desired speed. If a switch cannot be
operated, the system returns to the set
speed when you release your foot from the
accelerator pedal.
CAUTION
The warnings and brake control do not
operate while the accelerator pedal is
depressed.

When Driving
Mazda Radar Cruise Control (MRCC)
NOTE
 y When accelerating using the SET
switch while in headway control, the set
vehicle speed can be adjusted but
acceleration is not possible. If there is
no longer a vehicle ahead, acceleration
continues until reaching the set vehicle
speed. Check the set vehicle speed by
viewing the set vehicle speed display in
the active driving display.
 y When depressing the accelerator pedal,
the inter-vehicle distance display in
the display in the instrument cluster
changes to the white-line display.
 y The minimum settable speed is 30 km/h
(19 mph). If the set vehicle speed
reaches 30 km/h (19 mph) using the
switch operation, constant speed travel
is maintained at about 30 km/h (19
mph) even if the SET
switch is pressed.

 y  If the gears are not shifted up even
though the shift-up request indication
is displayed, load will be applied
to the engine and the Mazda Radar
Cruise Control (MRCC) system may
be automatically canceled or engine
damage could occur.
 y If the gears are not shifted down even
though the shift-down request indication
is displayed, the Mazda Radar Cruise
Control (MRCC) system may be
automatically canceled or engine
