Power Steering
ï‚·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.
ï‚·The warning light not ifies the driver of
system abnormalities and operation
conditions.
In addition, the buzzer may also activate
depending on the system abnormality or

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 drivin g 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 sol ely on the systems.
â–¼Active Safety Technology

High Beam Control System (HBC)*
The 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 4-23.
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 appr oaching in the opposite
direction.
The system switches the headlights to low beams when one of the following occurs:
ï‚·The system detects a vehicle or the headlights/lights of a vehicle approaching in the
opposite direction.
ï‚·The vehicle is driven on roads lin ed with streetlamps or on roads in well-lit cities and
towns.
ï‚·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 Lights on page 4-24.
CAUTION

Do not adjust the vehicle height, modify the headlight units, or remove the camera,
otherwise the system will not operate normally.

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 b y notifying the driver of the presence of vehicles
approaching from the rear in an adjacent lane.
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 notifie s the driver by turning on the
BSM warning indicator light and displaying the vehicle detectio n screen (vehicles with
active driving display).
If the turn signal lever is operated to signal a turn in the di rection in which the BSM
warning indicator light is illuminated while the approaching ve hicle is detected, the BSM
notifies the driver of possible danger by turning on the BSM wa rning indicator light, and by
activating the warning sound and the warning screen indicator d isplay (vehicles with active
driving display).
The detection area on this system covers the driving lanes on b oth sides of the vehicle and
from the rear part of the front doors to about 50 m (164 ft) behind the vehicle.
