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. Use the sport mode
when higher vehicle response is required such as merging onto expressway or accelerating
to overtake.

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 to cancel the sport mode on normal
driving.

Drive mode cannot be switched in the following conditions:

ABS/TCS/DSC is operating

Steering wheel is being operated abruptly

Pull the drive selection switch back
(“

”) to cancel the sport mode.

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 Indicator Light

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

NOTE

If the drive selection cannot be switched
to sport mode, the select mode indicator
light

When Driving

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.

In addition, the buzzer may also activate

depending on the system abnormality or
operation condition.

Refer to Warning Lights on page

4-38 .

Refer to Power Steering Warning Buzzer

on page 7-53 .

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. 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.

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 4-38 .
  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

À ashes when the system has a malfunction.

Refer to Warning Lights on page 4-38 .

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.
