When Driving
Forward Obstruction Warning (FOW)
Forward Obstruction Warning (FOW)
Forward Obstruction Warning (FOW) is a system which alerts the driver of a possible
collision using an indicator and warning sound in the instrument cluster while the vehicle
is being driven at about 15 km/h or faster (10 mph or faster) and the system's radar sensor
determines that your vehicle may hit a vehicle or obstruction ahead.
WARNING
Do not rely completely on the Forward Obstruction Warning (FOW) system and always
drive carefully:
Forward Obstruction Warning (FOW) is only designed to reduce damage in the event of
a collision. The ability to detect an obstruction is limited depending on the obstruction,
weather conditions, or traffi c conditions. Therefore, if the accelerator pedal or brake
pedal is mistakenly operated it could result in an accident. Always verify the safety of the
surrounding area and depress the brake pedal or accelerator pedal while keeping a safe
distance from vehicles ahead or on-coming vehicles.
NOTE
 


y The Forward Obstruction Warning (FOW) system operates when all of the following
conditions are met:
 


y The ignition is switched ON.



y The Forward Obstruction Warning (FOW) system is on.



y The vehicle speed is about 15 km/h (10 mph) or faster.



y The relative speed between your vehicle and the vehicle or obstruction ahead is about
15 km/h (10 mph) — 145 km/h (90 mph).
 


y The Forward Obstruction Warning (FOW) system may not operate under the following
conditions:
 


y If there is the possibility of hitting only a part of a vehicle or obstruction ahead.



y If the vehicle is accelerated rapidly and it comes close to a vehicle ahead.



y The DSC is malfunctioning.



y The vehicle is driven at the same speed as the vehicle ahead.



y The accelerator pedal is depressed.



y The brake pedal is depressed.



y The steering wheel is being operated.



y The selector lever is being operated.



y The turn signal is being used.

When Driving
Forward Obstruction Warning (FOW)
 


y Although the objects which activate the system are 4-wheeled vehicles, the radar sensor
could detect the following objects, determine them to be an obstruction, and operate the
Forward Obstruction Warning (FOW) system.
 


y Objects on the road at the entrance to a curve (including guardrails and snow banks).



y A vehicle appears in the opposite lane while cornering or rounding a curve.



y When crossing a narrow bridge.



y When passing under a low gate or through a tunnel or narrow gate.



y When entering an underground parking area.



y Metal objects, bumps, or protruding objects on the road.



y If you suddenly come close to a vehicle ahead.



y When driving in areas where there is high grass or forage.



y Two-wheeled vehicles such as motorbikes or bicycles.



y Pedestrians or non-metallic objects such as standing trees.




y When the system operates, the user is notifi ed by the fl ashing warning light and the active
driving display.
 


y The indicator light turns on when the system has a malfunction.

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 ).
Airfl 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.
NOTE
Use the temperature control dial to
increase the air fl 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.
NOTE
To prevent damage to the wiper arm
blades when raising both the driver and
passenger side wiper arms, raise the
driver side wiper arm fi rst. Conversely,
when setting down the wiper arms, set the
passenger side wiper arm down fi rst.
1. Raise the wiper arm.
2. Open the clip and slide the blade
assembly in the direction of the arrow.

Washing
CAUTION
 


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 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 AUTO 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.
To help protect the fi 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 fi 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.
NOTE
 


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 fi nishes.
To minimize scratches on the vehicle's
paint fi 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.
CAUTION
Do not use steel wool, abrasive
cleaners, or strong detergents
containing highly alkaline or caustic
agents on chrome-plated or anodized
aluminum parts. This may damage the
protective coating; also, cleaners and
detergents may discolor or deteriorate
the paint.
