When Driving
ABS/TCS/DSC
*Some models.
Dynamic Stability
Control (DSC)
*
The Dynamic Stability Control (DSC)
automatically controls braking and engine
torque in conjunction with systems such
as ABS and TCS to help control side slip
when driving on slippery surfaces, or
during sudden or evasive manoeuvring,
enhancing vehicle safety.

Refer to ABS (page 4-86 ) and TCS
(page 4-87 ).

DSC operation is possible at speeds
greater than 20 km/h (12 mph).

The warning light turns on when the
system has a malfunction.
Refer to Warning Lights on page 4-38 .
WARNING
Do not rely on the Dynamic Stability
Control as a substitute for safe driving:
The Dynamic Stability Control (DSC)
cannot compensate for unsafe and
reckless driving, excessive speed,
tailgating (following another vehicle
too closely), and hydroplaning (reduced
tyre friction and road contact because
of water on the road surface). You can
still have an accident.
CAUTION
  The DSC may not operate correctly
unless the following are observed:
 


 Use tyres of the correct size
speci¿ ed for your Mazda on all
four wheels.
 


 Use tyres of the same
manufacturer, brand and tread
pattern on all four wheels.
 


 Do not mix worn tyres. 

 The DSC may not operate correctly
when tyre chains are used or a
temporary spare tyre is installed
because the tyre diameter changes.
TCS/DSC Indicator Light

This indicator light stays on for a few
seconds when the ignition is switched
ON. If the TCS or DSC is operating, the
indicator light À ashes.

If the light stays on, the TCS, DSC
or the brake assist system may have a
malfunction and they may not operate
correctly. Take your vehicle to an expert
repairer, we recommend an Authorised
Mazda Repairer.

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.
Active Safety Technology
Active Safety Technology supports safer driving by helping the driver to recognise potential
hazards and avert accidents.

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.

4–111
When Driving
i-ACTIVSENSE
*Some models.
Lane Departure Warning System (LDWS) *
The LDWS system noti¿ es the driver that the vehicle may be deviating from its lane.
The system detects the white or yellow lines on the traf¿ c lane using the Forward Sensing
Camera (FSC) and if it determines that the vehicle may be deviating from its lane, it noti¿ es
the driver using the active driving display (vehicles with active driving display), and by
À ashing the LDWS warning light and activating the LDWS warning beep.
Use the LDWS when you drive the vehicle on roads with white or yellow lines.
Refer to Forward Sensing Camera on page 4-170 .


Forward Sensing Camera (FSC)

The warning light illuminates when the system has a malfunction.
Refer to Warning Lights on page 4-38 .
WARNING
Do not use the LDWS under the following conditions:
The system may not operate adequately according to the actual driving conditions,
resulting in an accident.
 
 Driving on roads with tight curves. 
 Driving under bad weather conditions (rain, fog, and snow).

The functions of the LDWS have limitations:
Always stay on course using the steering wheel and drive with care. The system is not
designed to compensate for a driver’s lack of caution and if you rely too much on the
LDWS it could lead to an accident. The driver is responsible for assuring lane changes
and other manoeuvres. Always pay attention to the direction in which the vehicle is
travelling and the vehicle’s surroundings.

4–112
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.
NOTE
  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 centre of the
lane.
  When the direction indicator lever is operated for a lane change, the LDWS warning
is automatically cancelled. The LDWS warning becomes operable when the direction
indicator lever is returned and the system detects the white or yellow lines.
  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 cancelled.
  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.
  The LDWS does not operate if it does not detect the white or yellow lines of the traf¿ c
lane.

When The System Operates
1. The system goes on operation standby
when the LDWS OFF switch is pressed
and the LDWS OFF indicator light in
the instrument cluster turns off.


2. Drive the vehicle in the centre of the
driving lane while the LDWS OFF
indicator light is turned off. The system
becomes operational when all of the
following conditions are met.
 

 
 The vehicle is driven in the centre
of the driving lane with the white
or yellow lines on the left and right
sides, or on either side.
 

 
 The vehicle speed is 70 km/h
(44 mph) or faster.
 

 
 The vehicle is driven on a straight
road or road with gentle curves.

The LDWS does not operate in the
following cases:
 

 
 The system cannot detect white or
yellow lines.
 

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

 
 The vehicle is making a sharp turn.


 
 The vehicle is making a curve at an
inadequate speed.

NOTE
  The LDWS does not operate until the
system detects a white or yellow line
on either the left or right.
  When the system detects a white
or yellow line on one side only, the
system will activate the warning only
when the vehicle deviates on the side
where the white or yellow line is
being detected.
  The distance and warning sensitivity
(likelihood of a warning) which
the system uses to determine the
possibility of a lane departure can be
changed.
 Refer to Personalisation Features on
page 9-13 .
Auto cancel
In the following cases, the LDWS cancels
automatically and the LDWS warning
light in the instrument cluster turns on.
 


 The temperature inside the camera is
high or low.
 


 The windscreen around the camera is
foggy.
 


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

The LDWS is enabled automatically when
the operation conditions are met, and the
LDWS warning light turns off.

4–115
When Driving
i-ACTIVSENSE
Auto cancel warning
When the following operations are
performed, the LDWS determines that
the driver intends to make a lane change
and the LDWS warning is cancelled
automatically. The LDWS is enabled
automatically after the driver performs the
operation.
 


 The steering wheel is operated abruptly.



 The brake pedal is depressed abruptly.



 The accelerator pedal is depressed
abruptly.
 


 The direction indicator lever is operated
(after the direction indicator lever is
returned, the LDWS may not operate for
about 3 seconds which is the period of
time required to make a lane correction).

NOTE
After about 60 seconds have elapsed
with the direction indicator lever left
operating, the LDWS warning may
operate if the vehicle is close to a white
or yellow line.
Cancelling The System
Press the LDWS OFF switch to cancel the
LDWS. The LDWS OFF indicator light
turns on.


LDWS Warning
If the system determines that there is the
possibility of a lane departure, the LDWS
warning beep activates and the LDWS
warning light À ashes. Operate the steering
wheel appropriately and steer the vehicle
to the centre of the lane.
For vehicles equipped with the active
driving display, if there is the possibility of
a lane departure, the system indicates the
direction it determines that the vehicle is
deviating in the active driving display.

*Some models.
Blind Spot Monitoring (BSM) System *
The Blind Spot Monitoring (BSM) is designed to assist the driver in checking the area to the
rear of the vehicle on both sides during lane changes by notifying the driver of the presence
of vehicles approaching from the rear in an adjacent lane.
The Blind Spot Monitoring (BSM) detects vehicles approaching from the rear while
travelling in the forward direction at a speed of 30 km/h (19 mph) or faster and noti¿ es
the driver by turning on the Blind Spot Monitoring (BSM) warning indicator light and
displaying the vehicle detection screen (vehicles with active driving display).
If the direction indicator lever is operated to signal a turn in the direction in which the
Blind Spot Monitoring (BSM) warning indicator light is illuminated while the approaching
vehicle is detected, the Blind Spot Monitoring (BSM) noti¿ es the driver of possible danger
by turning on the Blind Spot Monitoring (BSM) warning indicator light, and by activating
the warning sound and the warning screen indicator display (vehicles with active driving
display).
The detection area on this system covers the driving lanes on both sides of the vehicle and
from the rear part of the front doors to about 50 m (164 ft) behind the vehicle.
