NOTElIn the following cases, the Forward Sensing Camera (FSC) cannot detect target objects correctly,
and each system may be unable to operate normally.
lThe height of the vehicle ahead is low.lYou drive your vehicle at the same speed as the vehicle ahead.lHeadlights are not turned on during the night or when going through a tunnel.lIn the following cases, the Forward Sensing Camera (FSC) may not be able to detect target
objects correctly.
lWhen driving next to walls with no patterning (including fences and longitudinally striped
walls).
lThe taillights of the vehicle ahead are turned off.lA vehicle is outside the illumination range of the headlights.lThe vehicle is making a sharp curve, or ascending or descending a steep slope.lEntering or exiting a tunnel.lHeavy luggage is loaded causing the vehicle to tilt.lStrong light is shone at the front of the vehicle (back light or high-beam light from on-coming
vehicles).
lThere are many light emitters on the vehicle ahead.lWhen the vehicle ahead is not equipped with taillights or the taillights are turned off at
nighttime.
lThe vehicle ahead has a special shape.

NOTElUnder 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.
lThe 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.
lVehicles ahead with low vehicle height and thus less area for reflecting radio waves.lVisibility is reduced due to a vehicle ahead casting off water, snow, or sand from its tires and
onto your windshield.
lThe trunk/luggage compartment is loaded with heavy objects or the rear passenger seats are
occupied.
lIce, snow, or soiling is on the front surface of the front emblem.lDuring inclement weather such as rain, snow, or sand storms.lWhen driving near facilities or objects emitting strong radio waves.lUnder the following conditions, the radar sensor (front) may not be able to detect vehicles ahead
or obstructions.
lThe beginning and end of a curve.lRoads with continuous curves.lNarrow lane roads due to road construction or lane closures.lThe vehicle ahead enters the radar sensor's blind spot.lThe vehicle ahead is running abnormally due to accident or vehicle damage.lRoads with repeated up and down slopeslDriving on poor roads or unpaved roads.lThe distance between your vehicle and the vehicle ahead is extremely short.lA vehicle suddenly comes close such as by cutting into the lane.lTo 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).
lIf the battery power is weak, the system may not operate correctly.lWhen driving on roads with little traffic and few vehicles ahead or obstructions for the radar
sensor (front) to detect,“Radar blocked”may be temporarily displayed, however, this does not
indicate a problem.

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:
lIncorrect tire pressurelImproper wheel alignmentlOut-of-balance wheellSevere braking
After rotation, inflate all tire pressures to
specification (page 9-8) 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 4-150.
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.
qReplacing a Tire
WARNING
Always use tires that are in good
condition:
Driving with worn tires is dangerous.
Reduced braking, steering, and
traction could result in an accident.
Replace all four tires at the same time:
Replacing just one tire is dangerous.
It could cause poor handling and
poor braking resulting in loss of
vehicle control. Mazda strongly
recommends that you replace all four
tires at the same time.
If a tire wears evenly, a wear indicator
will appear as a solid band across the
tread.
Replace the tire when this happens.
New treadTread wear indicator
Worn tread
You should replace the tire before the
band crosses the entire tread.
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 4-150.
