When Driving
Radar Sensor
NOTE
 y In the following cases, the radar sensor may not be able to detect vehic\
les ahead or
obstructions.
 y The rear surface of a vehicle ahead does not refl 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.
 y Vehicles ahead with low vehicle height and thus less area for refl ecting radio waves. y Visibility is reduced due to a vehicle ahead casting off water, snow, or sand from its
tires and onto your windshield.
 y The trunk/luggage compartment is loaded with heavy objects or the rear passenger
seats are occupied.
 y Ice, snow, or soiling is on the front surface of the front emblem. y During inclement weather such as rain, snow, or sand storms. y When driving near facilities or objects emitting strong radio waves.
 y In the following cases, the radar sensor may detect vehicles in the oppo\
site lane or
surrounding obstructions, or it may not be able to detect vehicles ahead or \
obstructions.
 y The beginning and end of a curve. y Roads with continuous curves. y Narrow lane roads due to road construction or lane closures. y The vehicle ahead enters the radar sensor's blind spot. y The vehicle ahead is running abnormally due to accident or vehicle damag\
e.  y Roads with repeated up and down slopes y Driving on poor roads or unpaved roads. y The distance between your vehicle and the vehicle ahead is extremely short. y A vehicle suddenly comes close such as by cutting into the lane.
 y To prevent incorrect operation of the system, use tires of the same specifi 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)
 y If the battery power is weak, the system may not operate correctly. y When driving on roads with little traffi c and few vehicles ahead or obstructions for the
radar sensor to detect, Forward Obstruction Warning/Smart City Brake Support (FOW/
SCBS) warning light (amber) temporarily illuminates, however, this does not indicate a
problem.

Maintenance and Care
Owner Maintenance
Tires
For reasons of proper performance, safety,
and better fuel economy, always maintain
recommended tire infl ation pressures and
stay within the recommended load limits
and weight distribution.
WARNING
Using Diff erent Tire Types:
Driving your vehicle with diff erent
types of tires is dangerous. It could
cause poor handling and poor braking;
leading to loss of control.
Except for the limited use of the
temporary spare tire, use only the
same type tires (radial, bias-belted,
bias-type) on all four wheels.

Using Wrong-Sized Tires: Using any other tire size than what is
specifi ed for the vehicle (page 9-10 )
is dangerous. It could seriously aff ect
ride, handling, ground clearance,
tire clearance, and speedometer
calibration. This could cause you to
have an accident. Use only tires that
are the correct size specifi ed for the
vehicle.
Tire Infl ation Pressure
WARNING
Always infl ate the tires to the correct
pressure: Overinfl ation or underinfl ation of tires
is dangerous. Adverse handling or
unexpected tire failure could result in a
serious accident.
Refer to Tires on page 9-10 .

Use only a Mazda-genuine tire valve
cap: Use of a non-genuine part is
dangerous as the correct tire air
pressure cannot be maintained if the
tire valve becomes damaged. If the
vehicle is driven under this condition,
the tire air pressure will decrease which
could result in a serious accident. Do
not use any part for the tire valve cap
that is not a Mazda-genuine part.
Inspect all tire pressures monthly
(including the spare) when the tires are
cold. Maintain recommended pressures for
the best ride, handling, and minimum tire
wear.
Refer to the specifi cation charts (page
9-10 ).
After adjusting the tire pressure,
initialization of the tire pressure
monitoring system is necessary to make
the system operates normally.
Refer to Tire Pressure Monitoring System
Initialization on page 4-106 .

Maintenance and Care
Owner Maintenance
NOTE
 y Always check tire pressure when tires
are cold.
 y Warm tires normally exceed
recommended pressures. Do not release
air from warm tires to adjust the
pressure.
 y Underinfl ation can cause reduced fuel
economy, uneven and accelerated tire
wear, and poor sealing of the tire bead,
which will deform the wheel and cause
separation of tire from rim.
 y Overinfl ation can produce a harsh ride,
uneven and accelerated tire wear, and a
greater possibility of damage from road
hazards.
 Keep your tire pressure at the correct levels. If one frequently needs infl ating,
have it inspected.
Tire Rotation
WARNING
Rotate tires periodically: Irregular tire wear is dangerous. To
equalize tread wear for maintaining
good performance in handling and
braking, rotate the tires every 12,000
km (7,500 miles). However Mazda
recommends to rotate every 8,000 km
(5,000 miles) to help increase tire life
and distribute wear more evenly.
Refer to Scheduled Maintenance on
page 6-4 .
During rotation, inspect them for correct
balance.
Do not include (TEMPORARY USE ONLY)
spare tire in rotation.
Forward
Also, inspect them for uneven wear and
damage. Abnormal wear is usually caused
by one or a combination of the following:
 y
 Incorrect tire pressure y Improper wheel alignment y Out-of-balance wheel y Severe braking
After rotation, infl ate all tire pressures to
specifi cation (page 9-10 ) and inspect the
lug nuts for tightness.
After adjusting the tire pressure,
initialization of the tire pressure
monitoring system is necessary to make
the system operates normally.
Refer to Tire Pressure Monitoring System
Initialization on page 4-106 .
CAUTION
Rotate unidirectional tires and radial
tires that have an asymmetrical tread
pattern or studs only from front to rear,
not from side to side. Tire performance
will be reduced if rotated from side to
side.

Spare Tire
Your Mazda has a temporary spare tire.
The temporary spare tire is lighter and
smaller than a conventional tire, and is
designed only for emergency use and
should be used only for VERY short
periods. Temporary spare tires should
NEVER be used for long drives or
extended periods.
WARNING
Do not install the temporary spare tire
on the front wheels (driving wheels): Driving with the temporary spare tire
on one of the front driving wheels is
dangerous. Handling will be aff ected.
You could lose control of the vehicle,
especially on ice or snow bound roads,
and have an accident. Move a regular
tire to the front wheel and install the
temporary spare tire to the rear.
