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. At the same time,
the High Beam Control System (HBC)
indicator light (green) in the instrument
cluster illuminates.
The High Beam Control System (HBC)
determines that it is dark based on the
brightness of the surrounding area.
NOTE
  When the vehicle speed is 30 km/h
(18 mph) or higher, 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 9-16 .
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.

Lane Departure Warning System (LDWS) *
The LDWS notifi es the driver that the vehicle may be deviating from its lane.
The system detects the white or yellow lines on the traffi c lane using the Forward Sensing
Camera (FSC). If it determines that the vehicle may be deviating from its lane, it notifi es
the driver by fl ashing the LDWS indicator light (green) and operating the LDWS warning
sound.
Refer to Forward Sensing Camera on page 4-148 .
Use the LDWS when you drive the vehicle on roads with white or yellow lines.

Rear Vehicle Monitoring (RVM) System *
















 The rear vehicle monitoring system is designed to assist the driver in verifying the area
to the rear of the vehicle on both sides during lane changes by alerting the driver of the
presence of vehicles approaching from the rear in an adjacent lane. The system's detection
area extends from the area near the rear edge of the vehicle's front doors to a distance of
about 50 m (164 ft) rearward on both the left and right adjacent lanes. When the system
detects an approaching vehicle, it illuminates the RVM warning indicator light equipped
on the left and right outside mirrors depending on the conditions. If the direction indicator
is operated to either side where the RVM warning indicator light is illuminated, the RVM
warning indicator light starts fl ashing and a warning chime sounds to alert the driver.




 A system malfunction or operation conditions are indicated by a warning.
 Refer to Warning/Indicator Lights on page 7-35 , 4-118 .
 Refer to Rear Vehicle Monitoring (RVM) System Warning Chime on page 7-52 .
Detection area Your vehicle
WARNING
This system is only designed to assist the driver in verifying the area to the rear of the
vehicle before changing vehicle lanes. Before changing vehicle lanes, always verify the
area surrounding the vehicle visually. Due to various limitations on the operation of the
rear vehicle monitoring system, the RVM warning indicator light may not illuminate or
it could be delayed even though another vehicle is present in an adjacent vehicle lane.
Do not rely solely on this system and always verify the area surrounding the vehicle
visually.

RVM Warning Indicator Light
The rear vehicle monitoring system alerts the driver to the presence of another vehicle in
an adjacent lane using the RVM warning indicator lights and the warning chime while the
system is operational.
RVM warning indicator light
The RVM warning indicator lights are installed to the left and right outside mirrors. The
warning indicator light illuminates when a vehicle approaching from the rear in an adjacent
lane is detected. A warning indicator light fl ashes when the direction indicator lever is
operated to the side where the RVM warning indicator light is illuminated to alert the driver.
Illumination dimmer cancel function
Normally, when the headlight switch is turned to the
or position, the brightness of
the RVM warning indicator lights is dimmed when they illuminate.
When driving on snow and fog bound roads where the brightness of the surrounding light
makes it diffi cult to see a RVM warning indicator light while it is dimmed, rotating the
instrument panel illumination knob clockwise fully cancels the dimmer function and restores
the brightness of the RVM warning indicator lights to full brightness.
Refer to Instrument panel Illumination on page 4-28 .

Indication on Display
The Distance Recognition Support System (DRSS) operation status is indicated in the active
driving display. Regarding malfunctions, check the vehicle conditions or have it inspected
by an expert repairer, we recommend an Authorised Mazda Repairer according to the
content of the displayed message.
Refer to Warning/Indicator Lights on page 4-40 .
NOTE
  When the ignition is switched off, the operation status before the system was turned
off is maintained. For example, if the ignition is switched off with the Distance
Recognition Support System (DRSS) operable, the system will be operable when the
ignition is switched ON the next time.
  The Distance Recognition Support System (DRSS) can be turned on/off and the
system's sensitivity can be changed.

When Driving

NOTE
  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.
  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 transaxle) is
operated and any intended engine braking will not occur. If deceleration is required,
lower the vehicle speed setting or depress the brake pedal.
  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 travelling at a constant speed and
following a vehicle ahead.
  The Mazda Radar Cruise Control (MRCC) warning light (amber) fl ashes when the
system has a malfunction.

When Driving
Tyre Pressure Monitoring System
Tyre Pressure Monitoring System *
The Tyre Pressure Monitoring System (TPMS) monitors the air pressure of all four tyres. If
the air pressure of one or more tyres is too low, the system warns the driver by indicating the
tyre pressure monitoring system warning light in the instrument cluster and operating a beep
sound. The system monitors the tyre pressures indirectly using the data sent from the ABS
wheel speed sensors.
To allow the system to operate correctly, the system needs to be initialized with the specifi ed
tyre pressure (value on the tyre pressure label). Follow the procedure and perform the
initialization.
Refer to Tyre Pressure Monitoring System Initialization on page 4-164 .
The warning light fl ashes when the system has a malfunction.
