*Some models.
Radar Sensors (Rear) *
Your vehicle is equipped with radar sensors (rear). The following systems also use the radar
sensors (rear).
 


y Blind Spot Monitoring system (BSM)



y Rear Cross Traf¿ c Alert (RCTA)
The radar sensors (rear) function by detecting the radio waves reÀ ected off a vehicle
approaching from the rear or an obstruction sent from the radar sensor.

Radar sensors (rear)

The radar sensors (rear) are installed inside the rear bumper, one each on the left and right
sides.
Always keep the surface of the rear bumper near the radar sensors (rear) clean so that the
radar sensors (rear) operate normally. Also, do not apply items such as stickers.
Refer to Exterior Care on page 6-59 .
CAUTION
If the rear bumper receives a severe impact, the system may no longer operate normally.
Stop the system immediately and have the vehicle inspected at an Authorized Mazda
Dealer.

y The detection ability of the radar sensors (rear) has limitations. In the following cases,
the detection ability may lower and the system may not operate normally.
 


y The rear bumper near the radar sensors (rear) has become deformed.



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



y Under bad weather conditions such as rain, snow and fog. 



y Under the following conditions, the radar sensors (rear) cannot detect target objects or it
may be dif¿ cult to detect them.




y Stationary objects on a road or a road side such as small, two-wheeled vehicles,
bicycles, pedestrians, animals, and shopping carts.
 


y Vehicle shapes which do not reÀ ect radar waves well such as empty trailers with a low
vehicle height and sports cars.
 


y Vehicles are shipped with the direction of the radar sensors (rear) adjusted for each
vehicle to a loaded vehicle condition so that the radar sensors (rear) detect approaching
vehicles correctly. If the direction of the radar sensors (rear) has deviated for some
reason, have the vehicle inspected at an Authorized Mazda Dealer.
 


y For repairs or replacement of the radar sensors (rear), or bumper repairs, paintwork,
and replacement near the radar sensors, consult an Authorized Mazda Dealer.
 


y Turn off the system while pulling a trailer or while an accessory such as a bicycle carrier
is installed to the rear of the vehicle. Otherwise, the radio waves emitted by the radar will
be blocked causing the system to not operate normally.
 


y The radar sensors are regulated by the relevant radio wave laws of the country in which
the vehicle is driven. If the vehicle is driven abroad, authorization from the country in
which the vehicle is driven may be required.

When Driving
Tire Pressure Monitoring System
*Some models.
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 speci¿ 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 4-129 .
The warning light À ashes when the system has a malfunction.
Refer to Warning Lights on page 4-25 .

Interior Features
Climate Control System
Windshield Defrosting and
Defogging
Set the mode selector dial to the
position and turn the fan control dial to the
desired speed.
In this position, the outside air position
is automatically selected, and when the
fan control dial is ON, the air conditioner
automatically turns on. The air conditioner
will directly dehumidify the air to the
front windshield and side windows (page
5-4 ). AirÀ ow amount will be increased.
WARNING
Set the temperature control to the hot
or warm position when defogging
(
position):
Using the
position with the
temperature control set to the cold
position is dangerous as it will cause
the outside of the windshield to fog up.
Your vision will be hampered, which
could lead to a serious accident.

N O T E
Use the temperature control dial to
increase the air À ow temperature and
defog the windshield more quickly.

Sunlight/Temperature Sensor
The climate control system measures
inside and outside temperatures, and
sunlight. It then sets temperatures inside
the passenger compartment accordingly.
CAUTION
Do not obstruct either sensor,
otherwise the climate control system
will not operate properly.

Maintenance and Care
Owner Maintenance
Wiper Blades
CAUTION
 


¾ Hot waxes applied by automatic car
washers have been known to aff ect the
wiper's ability to clean windows.
 


¾ To prevent damage to the wiper blades,
do not use gasoline, kerosene, paint
thinner, or other solvents on or near
them.
 


¾ When the wiper lever is in the AUTO
position and the ignition is switched ON,
the wipers may move automatically in
the following cases:
 


¾ If the windshield above the rain
sensor is touched.
 


¾ If the windshield above the rain
sensor is wiped with a cloth.
 


¾ If the windshield is struck with a hand
or other object.
 


¾ If the rain sensor is struck with a hand
or other object from inside the vehicle.
  Be careful not to pinch hands or fi ngers
as it may cause injury, or damage the
wipers. When washing or servicing the
vehicle, make sure the wiper lever is in
the OFF position.

Contamination of either the windshield or
the blades with foreign matter can reduce
wiper effectiveness. Common sources are
insects, tree sap, and hot wax treatments
used by some commercial car washes.

If the blades are not wiping properly,
clean the window and blades with a good
cleaner or mild detergent; then rinse
thoroughly with clean water. Repeat if
necessary.
Replacing Windshield Wiper
Blades
When the wipers no longer clean well, the
blades are probably worn or cracked.
Replace them.
CAUTION
To prevent damage to the wiper arms
and other components, do not try to
sweep the wiper arm by hand.

N O T E
When raising both windshield wiper arms,
raise the driver's side wiper arm ¿ rst.
When lowering the wiper arms, slowly
lower the wiper arm from the passenger's
side ¿ rst while supporting it with your
hand. Forcefully lowering the wiper arms
could damage the wiper arm and blade,
and may scratch or crack the windshield.

1. Raise the wiper arm.
2. Open the clip and slide the blade
assembly in the direction of the arrow.

CAUTION
 


¾ When the wiper lever is in the
position and the ignition is switched ON,
the wipers may move automatically in
the following cases:
 


¾ If the windshield above the rain
sensor is touched or wiped with a
cloth.
 


¾ If the windshield is struck with a hand
or other object from either outside or
inside the vehicle.
  Keep hands and scrapers clear of the
windshield when the wiper lever is in the

position and the ignition is
switched ON as fi ngers could be pinched
or the wipers and wiper blades damaged
when the wipers activate automatically.
  If you are going to clean the windshield,
be sure the wipers are turned off
completely (when it is most likely
that the engine is left running) this is
particularly important when clearing ice
and snow.
 


¾ Do not spray water in the engine
compartment. Otherwise, it could result
in engine-starting problems or damage
to electrical parts.
 


¾ When washing and waxing the vehicle,
be careful not to apply excessive force to
any single area of the vehicle roof or the
antenna. Otherwise, you could dent the
vehicle or damage the antenna.

To help protect the ¿ nish from rust
and deterioration, wash your Mazda
thoroughly and frequently, at least once a
month, with lukewarm or cold water.
If the vehicle is washed improperly, the
paint surface could be scratched. Here are
some examples of how scratching could
occur.

Scratches occur on the paint surface when:
 


y The vehicle is washed without ¿ rst
rinsing off dirt and other foreign matter.
 


y The vehicle is washed with a rough, dry,
or dirty cloth.
 


y The vehicle is washed at a car wash that
uses brushes that are dirty or too stiff.
 


y Cleansers or wax containing abrasives
are used.

N O T E
 


y Mazda is not responsible for scratches
caused by automatic car washes or
improper washing.
 


y Scratches are more noticeable on
vehicles with darker paint ¿ nishes.

To minimize scratches on the vehicle's
paint ¿ nish:




y Rinse off any dirt or other foreign matter
using lukewarm or cold water before
washing.
 


y Use plenty of lukewarm or cold water
and a soft cloth when washing the
vehicle. Do not use a nylon cloth.
 


y Rub gently when washing or drying the
vehicle.
 


y Take your vehicle only to a car wash
that keeps its brushes well maintained.
 


y Do not use abrasive cleansers or wax
that contain abrasives.
