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 4-40 .
While driving the vehicle at a speed of about 30 km/h (18 mph), 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 fl ashes when the system has a malfunction.
Refer to Warning Lights on page 4-41 .
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 suffi cient attention to safety. Switch the headlights between the
high beams and low beams manually if necessary.

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.

When Driving
i-ACTIVSENSE
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.
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 traffi 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 traffi c
lane.

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.

4–115
When Driving
i-ACTIVSENSE
NOTE
  The rear vehicle monitoring system operates when all of the following conditions are
satisfi ed:




 The ignition is switched ON.



 The RVM switch is pressed and the RVM indicator light (green) in the instrument
cluster is illuminated.
 


 The vehicle speed is about 30 km/h (19 mph) or higher. 

 The rear vehicle monitoring system does not operate under the following conditions:




 The vehicle speed falls below 30 km/h (19 mph) even though the RVM indicator
light (green) is illuminated.
 


 The shift lever is shifted into reverse (R) and the vehicle moves in reverse. 

 In the following cases, the system illuminates the RVM warning light (amber) in the
instrument cluster and stops the operation of the system. If the RVM warning light
(amber) continues to illuminate, have the system inspected at an Authorised Mazda
Dealer as soon as possible:
 


 A malfunction in the system, including the RVM warning indicator light, is detected.



 The position of the radar sensors (rear) has changed signifi cantly. The direction
in which the radar sensors (rear) are pointed is factory-adjusted specifi c to the
installation conditions for each vehicle so that they detect approaching vehicles
correctly. If the direction of the radar sensors (rear) has deviated for some reason, it
needs to be readjusted.
 


 Large quantities of snow or ice are on the rear bumper near the radar sensors (rear).



 Driving on snow-covered roads for long periods.



 The temperature surrounding the radar sensors (rear) becomes extremely high when
the vehicle is driven up-hill for long periods under hot summer weather conditions.
 


 The battery voltage is low. 

 There is a limit to the detection capability of the radar sensors (rear). In the following
cases, the rear vehicle monitoring system's detection capability may weaken and not
operate normally:
 


 The rear bumper near the radar sensors (rear) is deformed.



 Snow, ice or mud adheres to the area near the radar sensors (rear) on the rear
bumper.
 


 Under certain weather conditions including rain, snow, or fog.

When Driving
i-ACTIVSENSE
NOTE
  It might be impossible or diffi cult for the radar sensors (rear) to detect the following:




 Small, two-wheeled vehicles, bicycles, pedestrians, and stationary objects on or at
the edge of the road.
 


 Vehicles with body shapes off of which radar may not refl ect such as unloaded
trailers with a low vehicle height and sports cars.
 


 A vehicle is in the detection area in an adjacent lane to the rear but it is not
approaching. The system makes determinations based on the radar detection data
from approaching vehicles.
 


 Another vehicle is travelling at the same speed alongside the vehicle for extended
periods.
 


 Vehicles approaching from the opposite direction.



 Another vehicle which your vehicle is attempting to pass is in an adjacent lane.



 A vehicle is in an adjacent lane which is extremely wide. The radar sensors (rear)
detection area is set according to the lane width of general freeways.
 
 In the following cases, the RVM warning indicator light and the warning chime may
not activate or they may be delayed:
 


 Another vehicle moves from a lane two lanes over to the adjacent lane.



 When driving on a steep incline.



 When going over a mountain pass.



 When the turning radius is small (cornering around sharp curves, roundabouts, or
intersections).
 


 There is a difference in height between vehicle lanes.



 Immediately after this system is turned on. 

 If the lane width is extremely narrow, a vehicle in an adjacent lane two lanes over may
be detected. The radar sensors (rear) detection area is set according to the lane width of
general freeways.
