When Driving
Mazda Radar Cruise Control (MRCC)
 


y In the following cases, the warnings may not activate even if your vehicle starts closing
in on the vehicle ahead.
 


y You are driving at the same speed as the vehicle ahead.



y Directly after the Mazda Radar Cruise Control (MRCC) system has been set.



y When the accelerator pedal is depressed or directly after the accelerator pedal is
released.
 


y Another vehicle cuts into the driving lane.




y The following are not detected as physical objects.




y Vehicles approaching in the opposite direction



y Pedestrians



y Stationary objects (stopped vehicles, obstructions)




y If a vehicle ahead is traveling at an extremely low speed, the system may not detect it
correctly.
 


y During headway control travel, do not set the system on two-wheeled vehicles such as
motorcycles and bicycles.
 


y Do not use the Mazda Radar Cruise Control (MRCC) system under conditions in which
the close proximity warnings are frequently activated.
 


y 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.
 


y 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.
 


y 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 traveling at a constant speed and following a
vehicle ahead.
 


y The Mazda Radar Cruise Control (MRCC) warning light (amber) fl ashes when the
system has a malfunction.

When Driving
Tire Pressure Monitoring System
Tire Pressure Monitoring System *
The Tire Pressure Monitoring System (TPMS) monitors the air pressure of all four tires. If
the air pressure of one or more tires is too low, the system warns the driver by indicating the
tire pressure monitoring system warning light in the instrument cluster and operating a beep
sound. The system monitors the tire 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
tire pressure (value on the tire pressure label). Follow the procedure and perform the
initialization.
Refer to Tire Pressure Monitoring System Initialization on page 4-107 .
The warning light fl ashes when the system has a malfunction.
Refer to Warning Lights on page 4-22 .

When Driving
Tire Pressure Monitoring System
NOTE
Because this system detects slight changes in tire conditions, the timing of the warning may
be faster or slower in the following cases:
 


y The size, manufacturer, or the type of tires is different from the specifi cation.



y The size, manufacturer, or the type of a tire is different from the others, or the level of tire
wear is excessively different between them.
 


y A run-fl at tire, studless tire, snow tire, or tire chains are used.



y An emergency tire is used (The tire pressure monitoring system warning light may fl ash
and then continue illuminating).
 


y A tire is repaired using the puncture tire repair kit.



y The tire pressure is excessively higher than the specifi ed pressure, or the tire pressure is
suddenly lowered for some reason such as a tire burst during driving.
 


y The vehicle speed is lower than about 15 km/h (9.3 mph) (including when the vehicle is
stopped), or the drive period is shorter than 5 minutes.
 


y The vehicle is driven on an extremely rough road or a slippery, icy road.



y Hard steering and rapid acceleration/deceleration are repeated such as during
aggressive driving on a winding road.
 


y Load on the vehicle is applied to a tire such as by loading heavy luggage to one side of
the vehicle.
 


y System initialization has not been implemented with the specifi ed tire pressure.

3. Switch the ignition ON.
4. While the vehicle is parked, press
and hold the tire pressure monitoring
system set switch and verify that
the tire pressure monitoring system
warning light in the instrument cluster
fl ashes twice and a beep sound is heard
once.
CAUTION
If the system initialization is performed
without adjusting the tire pressure,
the system cannot detect the normal
tire pressure and it may not illuminate
the tire pressure monitoring system
warning light even if a tire pressure is
low, or it may illuminate the light even
if the pressures are normal.
The system initialization will not be
performed if the switch is pressed while
the vehicle is being driven.

When Driving
Blind Spot Monitoring (BSM) System
Blind Spot Monitoring (BSM) System
The Blind Spot Monitoring (BSM) system is designed to assist the driver by monitoring
blind spots on both sides of the vehicle to the rear in certain situations such as when
changing lanes on roads and freeways or reversing the vehicle from a parking garage.
The Blind Spot Monitoring (BSM) System consists of the Blind Spot Monitoring (BSM)
and Rear Cross Traffi c Alert (RCTA).
WARNING
Do not rely completely on the Blind Spot Monitoring (BSM) system. Always look over
your shoulder before changing lanes or reversing the vehicle from a parking garage:
The Blind Spot Monitoring (BSM) system can assist the driver in confi rming the safety of
the surroundings but is not a complete substitute. The driver is responsible for assuring
lane changes and other maneuvers. Always pay attention to the direction in which the
vehicle is traveling and the vehicle's surroundings.
NOTE
 


y The detectability of the radar sensors has its limitations. The Blind Spot Monitoring
(BSM) System may not operate properly under the following conditions:
 


y Ice, snow, or soil adheres to the rear bumper surface around the radar sensors.



y During adverse weather conditions such as rain or snow, or under conditions where
water is sprayed.
 


y The rear bumper area around the radar sensors is blocked by foreign material (such as
stickers or a bicycle carrier).
 


y The radar sensors do not detect human, animal, shopping cart, bicycle, or static objects
such as fences.
 


y The radar sensors may not detect all types of vehicles around your vehicle, especially the
following types of vehicles:
 


y Motorcycles



y Vehicles with body shapes that radar may not refl ect such as a fl atbed trailer with no
cargo.
 


y Vehicles with lower body height such as sports cars.




y Although the system may detect objects on the road side such as parked vehicles or
guardrails and operate the warning light/beep, it does not indicate a malfunction.
 


y If the vehicle is driven on a road with less traffi c and few vehicles that the radar sensors
can detect, the system may pause (the Blind Spot Monitoring (BSM) OFF indicator light
in the instrument cluster fl ashes). However, it does not indicate a malfunction.

When Driving
Blind Spot Monitoring (BSM) System
 


y The following conditions may affect the visibility of the Blind Spot Monitoring (BSM)
warning lights on the outside mirror, making it diffi cult to confi rm the illumination of the
lights:
 


y Ice or snow adheres to the surface of the outside mirrors.



y The door window glass is tinted.




y The radar sensors are equipped inside the rear bumper (page 4-114 ).



y Have the radar sensors inspected at an Authorized Mazda Dealer if any shock is applied
to the rear bumper, even in a minor accident. If the vehicle is driven with a damaged
radar sensor, the system may not operate properly resulting in an accident.
 


y For repairs or paintwork around the radar sensors, or replacement of the bumper,
consult an Authorized Mazda Dealer.
 


y The radar sensors of the Blind Spot Monitoring (BSM) system may be regulated under
the radio wave related laws of the country where the vehicle is driven. The sensors in this
system are approved for use in the U.S.A. (including territories), Canada, and Mexico.
If a vehicle with a Blind Spot Monitoring (BSM) system is driven in a country other
than the U.S.A., Canada, or Mexico, the system has to be turned off using the Blind Spot
Monitoring (BSM) OFF switch.
Blind Spot Monitoring (BSM)
The Blind Spot Monitoring (BSM) system monitors the detection areas on both sides of
the vehicle to the rear and when there are vehicles in the detection area it notifi es the driver
by illuminating the Blind Spot Monitoring (BSM) warning light while the vehicle speed is
about 10 km/h (6.2 mph) or faster and driving forward.
If the turn signal lever is operated to the side the Blind Spot Monitoring (BSM) warning
light is illuminated, the Blind Spot Monitoring (BSM) warning light fl ashes and the system
warns the driver of the vehicle in the detection area using a BSM warning beep sound.

When Driving
Blind Spot Monitoring (BSM) System
NOTE
 


y The Blind Spot Monitoring (BSM) does not operate when the vehicle speed is lower than
about 10 km/h (6.2 mph).
 


y The detection area of the Blind Spot Monitoring (BSM) has been determined based on
the lane width of general freeways. Therefore on a road with a narrower lane width, the
system may detect vehicles on a lane next to the adjacent lane and operate the warning
light/beep. On a road with wider lane width, the system may not detect vehicles on the
adjacent lane and may not operate the warning light/beep.
 


y Under the following conditions, the system may be unable to detect vehicles, or detection
may be delayed.
 


y The vehicle accelerates from a standing-start with a vehicle alongside.



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



y The difference in vehicle speed between your vehicle and another vehicle is larger
when passing or being passed, and the vehicle passes the detection area within a short
period of time.
 


y On a steep incline, or when there is a difference in height between lanes.



y Immediately after the system has been activated by pressing the Blind Spot Monitoring
(BSM) OFF switch again after it has been turned off (Blind Spot Monitoring (BSM)
OFF indicator light in instrument cluster illuminates) by pressing the switch.
 


y(Automatic transaxle vehicles)
 The shift lever is shifted to the R position, or directly after being shifted from the R
position.
 


y The system may not operate normally when towing a trailer. Turn off the system by
operating the Blind Spot Monitoring (BSM) OFF switch when towing a trailer.
 


y The system switches to the Rear Cross Traffi c Alert function when the shift lever (Manual
transaxle) or the selector lever (Automatic transaxle) is shifted to the R position.
