NOTE
  Under the following conditions, the radar sensor (front) may not be able to detect
vehicles ahead or obstructions correctly and each system may not operate normally.
  The rear surface of a vehicle ahead does not re fl ect radio waves effectively, such as
an unloaded trailer or an automobile with a loading platform covered by a soft top,
vehicles with a hard plastic tailgate, and round-shaped vehicles.
   Vehicles ahead with low vehicle height and thus less area for re fl ecting radio waves.   Visibility is reduced due to a vehicle ahead casting off water, snow, or sand from its
tires and onto your windshield.
  The luggage compartment is loaded with heavy objects or the rear passenger seats are
occupied.
  Ice, snow, or soiling is on the front surface of the front emblem.  During inclement weather such as rain, snow, or sand storms.  When driving near facilities or objects emitting strong radio waves.   Under the following conditions, the radar sensor (front) may not be able to detect
vehicles ahead or obstructions.
  The beginning and end of a curve.  Roads with continuous curves.  Narrow lane roads due to road construction or lane closures.  The vehicle ahead enters the radar sensor's blind spot.  The vehicle ahead is running abnormally due to accident or vehicle damag\
e.  Roads with repeated up and down slopes  Driving on poor roads or unpaved roads.  The distance between your vehicle and the vehicle ahead is extremely short.  A vehicle suddenly comes close such as by cutting into the lane.   To prevent incorrect operation of the system, use tires of the same speci fi ed size,
manufacturer, brand, and tread pattern on all four wheels. In addition, do not use tires
with signifi cantly different wear patterns or tire pressures on the same vehicle (Including
the temporary spare tire).
   If the battery power is weak, the system may not operate correctly.  When driving on roads with little traf fi c and few vehicles ahead or obstructions for
the radar sensor (front) to detect, “Front Radar Sensor Blocked” may be temporarily
displayed, however, this does not indicate a problem.

  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.
  The rear bumper near the radar sensors (rear) has become deformed.  Snow, ice or mud adheres to the radar sensors (rear) on the rear bumper.  Under bad weather conditions such as rain, snow and fog.   Under the following conditions, the radar sensors (rear) cannot detect target objects or it
may be dif fi cult to detect them.
   Stationary objects on a road or a road side such as small, two-wheeled vehicles,
bicycles, pedestrians, animals, and shopping carts.
  Vehicle shapes which do not re fl ect radar waves well such as empty trailers with a low
vehicle height and sports cars.
   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.
  For repairs or replacement of the radar sensors (rear), or bumper repairs, paintwork,
and replacement near the radar sensors, consult an Authorized Mazda Dealer.
  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.
  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.

Tire Pressure Monitoring System
*Some models.
Tire Pressure Monitoring System *
The Tire Pressure Monitoring System (TPMS) monitors the pressure for each tire.
If tire pressure is too low in one or more tires, the system will inform\
the driver via the
warning light in the instrument cluster and by the warning beep sound.
Refer to Warning Indication/Warning Lights on page 4-33 .
Refer to Tire Infl ation Pressure Warning Beep on page 7-42 .

The tire pressure sensors installed on each wheel send tire pressure dat\
a by radio signal to
the receiver unit in the vehicle.

Tire pressure sensors
NOTE
When the ambient temperature is low due to seasonal changes, tire temperatures are also
lower. When the tire temperature decreases, the air pressure decreases as well. The TPMS
warning light may illuminate more frequently. Visually inspect the tires daily before driving,
and check tire pressures monthly with a tire pressure gauge. When checking tire pressures,
use of a digital tire pressure gauge is recommended.


TPMS does not alleviate your need to check the pressure and condition of\
all four tires
regularly.

System Error Activation
When the warning light fl ashes, there
may be a system malfunction. Consult an
Authorized Mazda Dealer.
A system error activation may occur in the
following cases:
   When there is equipment or a device
near the vehicle using the same radio
frequency as that of the tire pressure
sensors.
   When a metallic device such as a non-
genuine navigation system is equipped
near the center of the dashboard, which
may block radio signals from the tire
pressure sensor to the receiver unit.
   When using the following devices in the
vehicle that may cause radio interference
with the receiver unit.
 A digital device such as a personal computer.
 A current converter device such as a DC-AC converter.
   When excess snow or ice adheres to the
vehicle, especially around the wheels.
   When the tire pressure sensor batteries
are exhausted.
   When using a wheel with no tire
pressure sensor installed.
   When using tires with steel wire
reinforcement in the side walls.
   When using tire chains.
Tires and Wheels
CAUTION
When inspecting or adjusting the tire
air pressures, do not apply excessive
force to the stem part of the wheel unit.
The stem part could be damaged.

Changing tires and wheels
The following procedure allows the TPMS
to recognize a tire pressure sensor's unique
ID signal code whenever tires or wheels
are changed, such as changing to and from
winter tires.
NOTE
Each tire pressure sensor has a unique
ID signal code. The signal code must be
registered with the TPMS before it can
work. The easiest way to do it is to have an
Authorized Mazda Dealer change your tire
and complete ID signal code registration.

When having tires changed at an
Authorized Mazda Dealer
When an Authorized Mazda Dealer
changes your vehicle's tires, they will
complete the tire pressure sensor ID signal
code registration.

When changing tires yourself
If you or someone else changes tires, you
or someone else can also undertake the
steps for the TPMS to complete the ID
signal code registration.

1. After tires have been changed, switch the ignition ON, then back to ACC or
OFF.
2. Wait for about 15 minutes.
3. After about 15 minutes, drive the vehicle at a speed of at least 25 km/h
(16 mph) for 10 minutes and the tire
pressure sensor ID signal code will be
registered automatically.

NOTE
If the vehicle is driven within about 15
minutes of changing tires, the tire pressure
monitoring system warning light will fl ash
because the sensor ID signal code would
not have been registered. If this happens,
park the vehicle for about 15 minutes,
after which the sensor ID signal code will
register upon driving the vehicle for
10 minutes.

Replacing tires and wheels
CAUTION
 When replacing/repairing the tires or wheels or both, have the work done by
an Authorized Mazda Dealer, or the tire
pressure sensors may be damaged.
 The wheels equipped on your Mazda are specially designed for installation
of the tire pressure sensors. Do not use
non-genuine wheels, otherwise it may
not be possible to install the tire pressure
sensors.

Be sure to have the tire pressure sensors
installed whenever tires or wheels are
replaced.
When having a tire or wheel or both
replaced, the following types of tire
pressure sensor installations are possible.
   The tire pressure sensor is removed from
the old wheel and installed to the new
one.
   The same tire pressure sensor is used
with the same wheel. Only the tire is
replaced.
   A new tire pressure sensor is installed to
a new wheel.

NOTE
   The tire pressure sensor ID signal
code must be registered when a new
tire pressure sensor is purchased. For
purchase of a tire pressure sensor and
registration of the tire pressure sensor
ID signal code, consult an Authorized
Mazda Dealer.
  When reinstalling a previously removed
tire pressure sensor to a wheel, replace
the grommet (seal between valve body/
sensor and wheel) for the tire pressure
sensor.

Wiper Blades
CAUTION
 Hot waxes applied by automatic car washers have been known to aff ect the
wiper's ability to clean windows.
 To prevent damage to the wiper blades, do not use gasoline, kerosene, paint
thinner, or other solvents on or near
them.
 When the wiper lever is in the AUTO position and the ignition is switched ON,
the wipers may move automatically in
the following cases:
 If the windshield above the rain sensor is touched.
 If the windshield above the rain sensor is wiped with a cloth.
 If the windshield is struck with a hand or other object.
 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.
 Do not bend the blade rubber unnecessarily when replacing it.
Otherwise, the metal stiff ener in the
blade may deform and the windshield
wiper operation may be adversely
aff ected.

NOTE
When raising both windshield wiper arms,
raise the driver's side wiper arm fi rst.
When lowering the wiper arms, slowly
lower the wiper arm from the passenger's
side fi 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.
