 In the following cases, the Forward Sensing Camera (FSC) may not be able to detect
target objects correctly.
 Under bad weather condition, such as rain, fog and snow . The window washer is being used or the windshield wipers ar e not used when it's
raining. Ice, fog, snow, frost, rainfall, dirt, or foreign matter such as a plastic bag is stuck on
the windshield. Trucks with low loading platforms and vehicles with an extremely low or high profile. When driving next to walls with no patterning (including fences and lon\
gitudinally
striped walls). The taillights of the vehicle ahead ar e turned off. A vehicle is outside the illumination range of the headlights. The vehicle is making a sharp turn, or ascending or descending a steep s\
lope. Entering or exiting a tunnel. Heavy luggage is loaded causing the vehicle to tilt. Strong light is shone at the front of the vehicle (back light or high-beam light from on-
coming vehicles). There are many light emitters on the vehicle ahead. When the vehicle ahead is not equipped with taillights or the taillights\
ar e turned off at
nighttime. Elongated luggage or cargo is loaded onto installed roof rails and covers the Forward
Sensing Camera (FSC). Exhaust gas from the vehicle in front, sand, snow, and water vapor rising from
manholes and grating, and water splashed into the air. When towing a malfunctioning vehicle. The vehicle is driven with tir es having significantly different wear. The vehicle is driven on down slopes or bumpy r oads. There are water puddles on the road. The surroundings are dark such as during the night, early evening, or early morning,
or in a tunnel or indoor parking lot. The illumination brightness of the headlights is r educed or the headlight illumination
is weakened due to dirt or a deviated optical axis. The target object enters the blind spot of the Forward Sensing Camera (FSC). A person or object bursts onto the road from the shoulder or cuts right in front of you. You change lanes and approach a vehicle ahead. When driving extremely close to the target object. Tire chains or a temporary spare tire is installed. The vehicle ahead has a special shape. For example, a vehicle towing a t\
railer house
or a boat, or a vehicle carrier carrying a vehicle with its front pointed rearward.

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 reflect 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 reflecting radio waves. Visibility is reduced due to a vehicle ahead casting off water, snow, or sand from its
tires and onto your windshield. The trunk/luggage compartment is loaded with heavy objects or the r ear 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 str ong radio waves.
 Under the following conditions, the radar sensor (fr ont) 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 r oads or unpaved roads. The distance between your vehicle and the vehicle ahead is extr emely 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 specified size,
manufacturer, brand, and tread pattern on all four wheels. In addition, do not use tires
with significantly 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. If the vehicle is driven on a road with little traffic and few vehicles ahead or obstructions
for the radar sensor (front) to detect, the sensor detects that the radar sensor (front) is
dirty and the Smart Brake Support/Smart City Brake Support (SBS/SCBS) \
Warning Light
(amber) may be temporarily turned on. However, it does not indicate a malfunction.

Maintenance and Care
Owner Maintenance
NOTE
 Always check tire pressure when tires
are cold. Warm tires normally exceed
recommended pressures. Do not release
air from warm tires to adjust the
pressure.
 Underinflation can cause r educed 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.
 Overinflation 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 inflating,
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:
 Incorrect tire pressure Improper wheel alignment Out-of-balance wheel Severe braking
After rotation, inflate all tire pressures to
specification (page
9-10) and inspect the
lug nuts for tightness.
(With tire pressure monitoring system)
After adjusting the tire pressure,
initialization of the tire pressure
monitoring system is necessary to make
the system operate normally.
Refer to Tire Pressure Monitoring System
Initialization on page
4-154.
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.

Tire Maintenance
Improper or inadequate vehicle maintenance can cause tires to wear abnormally. Here are
some important maintenance points:
Tire Inflation Pressure
Inspect all tire pressure monthly (including the spare) when the tires\
are cold. Maintain
recommended pressures for the best ride, top handling, and minimum tire \
wear. Use the
pressures specified on the vehicle tire information placard or tire label for optimum service.
Tire Rotation
To equalize tread wear, rotate the tires every 12,000 km (7,500 miles) at the latest or sooner
if irregular wear develops. Mazda recommends to rotate every 8,000 km (\
5,000 miles) to
help increase tire life and distribute wear more evenly.
Do not include (TEMPORARY USE ONLY) spare tire in rotation.
Forward
Inspect the tires for uneven wear and damage. Abnormal wear is usually caused by one or a
combination of the following:
 Incorrect tire pressure Improper wheel alignment Out-of-balance wheel Severe braking
After rotation, inflate all tire pressures to specification (page 9-10) and inspect the lug
nuts for tightness.
(With tire pressure monitoring system)
After adjusting the tire pressure, initialization of the tire pressure m\
onitoring system is
necessary to make the system operate normally.
Refer to Tire Pressure Monitoring System Initialization on page
4-154.
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 weakened if
rotated from side to side.
