i-ELOOP

*Some models.

i-ELOOP

i-ELOOP is a regenerative braking system. When you depress the brake pedal or use
engine braking, the kinetic energy that occurs is converted to electrical energy by the power
generator and the converted electrical energy is stored in the rechargeable battery (capacitor
and battery). The stored electricity is used as power to charge the battery and the vehicle's
electrical devices.

A variable voltage alternator is incorporated in the power generator which converts

the kinetic energy to electricity and can generate electricity ef

¿ ciently according to the

vehicle conditions.

A capacitor is used to store large amounts of electricity instantly which can be utilized

quickly.

A DC-DC converter is incorporated which steps down the stored electricity to voltage

useable by the vehicle's electrical devices.

When Driving

Drive Selection

*Some models.

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 enhanced. This provides
additional quick acceleration which may be needed to safely make manoeuvres 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 tyre 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

Cruise control is operating.

Steering wheel is being operated abruptly

NOTE

When the ignition is switched off, the

sport mode is cancelled.

Depending on the driving conditions

when sport mode is selected, the
vehicle may perform shift-down or
slightly accelerate.

Select Mode Indication

When the sport mode is selected, the select
mode indication turns on in the instrument
cluster.

NOTE

If the drive selection cannot be

Power Steering

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 expert repairer,
we recommend an Authorised Mazda
Repairer.

The warning light noti

¿ es the driver

of system abnormalities and operation
conditions.

Refer to Warning Indication/Warning

Lights on page 4-42 .

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.

i-ACTIVSENSE

*Some models.

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.
Because each system has its limitations, always drive carefully and do not rely solely on the
systems.

Camera and Sensors

Forward sensing camera (FSC)

The Forward Sensing Camera (FSC) determines the conditions ahead of the vehicle while
travelling at night and detects traf

¿ c lanes. The following systems also use the Forward

Sensing Camera (FSC).

High Beam Control system (HBC)

Lane Departure Warning System (LDWS)

The Forward Sensing Camera (FSC) is installed at the top of the windscreen near the
rearview mirror.
Refer to Forward Sensing Camera (FSC) on page 4-129 .

Radar sensors (rear)

The radar sensors (rear) function by detecting the radio waves re

À ected off a vehicle

approaching from the rear or an obstruction sent from the radar sensors. The following
systems also use the radar sensors (rear).

Blind Spot Monitoring (BSM) System

Rear Cross Traf

*Some models.

Adaptive Front Lighting System (AFS)

The  adaptive  front  lighting  system  (AFS)  automatically  adjusts  the  headlight  beams  to  the
left or right in conjunction with the operation of the steering wheel after the headlights have
been turned on.
  A system malfunction or operation conditions are indicated by a warning.
  Refer to Warning/Indicator Lights on page 4-42 .

NOTE

Headlights do not blind drivers approaching in the opposite direction no matter

what side of the road you must drive your vehicle (left-hand or right-hand traf

¿ c).

Therefore, it is not necessary to adjust the optical axis of the headlights when
switching temporarily to driving on the opposite side of the road (left-hand or right-
hand traf

¿ c).

The Adaptive Front Lighting System (AFS) function can be switched to operable/

inoperable using the personalisation function.

Refer to Personalisation Features on page 9-10 .

When Driving

i-ACTIVSENSE

*Some models.

High Beam Control System (HBC)

The  High  Beam  Control  System  (HBC)  determines  the  conditions  in  front  of  the  vehicle
using the Forward Sensing Camera (FSC) while driving in darkness to automatically switch
the headlights between high and low beams.
  Refer to Warning/Indicator Lights on page 4-42 .
  While driving the vehicle at a speed of about 30 km/h (19 mph) or more, the headlights are
switched to high beams when there are no vehicles ahead or approaching in the opposite
direction.
  The system switches the headlights to low beams when one of the following occurs:

The system detects a vehicle or the headlights/lights of a vehicle approaching in the

opposite direction.

The vehicle is driven on roads lined with streetlamps or on roads in well-lit cities and

towns.

The vehicle is driven at less than about 20 km/h (12 mph).

Forward Sensing
Camera (FSC)

The recognition distance of the
Forward Sensing Camera (FSC)
varies according to the
surrounding conditions.

The warning light turns on when the system has a malfunction.
Refer to Warning Indication/Warning Lights on page 4-42 .

CAUTION

Do not adjust the vehicle height, modify the headlight units, or remove the camera,

otherwise the system will not operate normally.

Do not rely excessively on the High Beam Control System (HBC) and drive the

vehicle while paying suf

¿ cient attention to safety. Switch the headlights between the

high beams and low beams manually if necessary.

/:A

4–104

When Driving

i-ACTIVSENSE

NOTE

The timing in which the system switches the headlights changes under the following
conditions. If the system does not switch the headlights appropriately, manually switch
between high and low beams according to the visibility as well as road and traf

¿ c

conditions.

When there are sources of light in the area such as street lamps, illuminated

signboards, and traf

¿ c signals.

When there are re

À ective objects in the surrounding area such as reÀ ective plates and

signs.

When visibility is reduced under rain, snow and foggy conditions.

When driving on roads with sharp turn or hilly terrain.

When the headlights/rear lamps of vehicles in front of you or in the opposite lane are

dim or not illuminated.

When there is suf

¿ cient darkness such as at dawn or dusk.

When the luggage compartment is loaded with heavy objects.

When visibility is reduced due to a vehicle in front of you spraying water from its tyres

onto your windscreen.

When Driving

i-ACTIVSENSE

To Operate the System

The High Beam Control System (HBC)
operates to switch the headlights
automatically between high and low
beams after the ignition is switched ON
and the headlight switch is in the AUTO
and high beam position.
The High Beam Control System (HBC)
determines that it is dark based on the
brightness of the surrounding area. At the
same time, the High Beam Control System
(HBC) indicator light (green) in the
instrument cluster illuminates.

NOTE

When the vehicle speed is about

30 km/h (19 mph) or more, the
headlights automatically switch
to high beams when there are no
vehicles ahead or approaching in the
opposite direction.

When the vehicle speed is less

than about 20 km/h (12 mph), the
High Beam Control System (HBC)
switches the headlights to low
beams.

The low beams may not switch to

high beams when cornering.

Operation of the High Beam Control

System (HBC) function can be
disabled. Refer to Personalisation
Features on page 9-10 .

Manual Switching

Switching to low beams

Shift the lever to the low beam position.
The High Beam Control System (HBC)
indicator light (green) turns off.

Switching to high beams

Turn the headlight switch to the
position.
The High Beam Control System (HBC)
indicator light (green) turns off and the
is illuminated.
