How to Set the Distance Between
Vehicles During Headway Control
The distance between vehicles is set to a
shorter distance each time the
switch is
pressed. The distance between vehicles is
set to a longer distance by pressing the
switch. The distance-between-vehicles can
be set to 4 levels; Long, medium, short,
and extremely short distance.
Distance-between-
vehicles guideline
(at 80 km/h (50 mph)
vehicle speed) Indication on display
Long (about 50 m (164
ft))
Medium (about 40 m
(131 ft))
Short (about 30 m (98
ft))
Extremely short (about
25 m (82 ft))
NOTE
 


y The distance between vehicles differs
depending on the vehicle speed, and the
slower the vehicle speed, the shorter the
distance.
 


y When the ignition is switched to ACC
or OFF and then the engine is started
again, the system automatically sets
the distance between vehicles to the
previous setting.
Changing the Set Vehicle Speed
Changing the set vehicle speed using the
SET
/ SET switch
Press the SET
switch to accelerate. Press
the SET
switch to decelerate. The set
vehicle speed changes as follows each
time the SET
/ SET switch is pressed.
Short press 1 km/h (1 mph)
Long press 10 km/h (5 mph)
NOTE
For example, the set vehicle speed is
changed by pressing the SET
/ SET
switch four times as follows:
The vehicle speed accelerates or
decelerates by 4 km/h (4 mph).
To accelerate using accelerator pedal
Depress the accelerator pedal and press
and release the SET
or SET switch at
the desired speed. If a switch cannot be
operated, the system returns to the set
speed when you release your foot from the
accelerator pedal.

Operating Tips
 












y Operate the climate control system with
the engine running.
 


y To prevent the battery from being
discharged, do not leave the fan control
dial on for a long period of time with the
ignition switched ON when the engine is
not running.
 


y Clear all obstructions such as leaves,
snow and ice from the hood and the air
inlet in the cowl grille to improve the
system effi ciency.




y Use the climate control system to defog
the windows and dehumidify the air.
 


y The recirculate mode should be used
when driving through tunnels or while in
a traffi c jam, or when you would like to
shut off outside air for quick cooling of
the interior.
 


y Use the outside air mode for ventilation
or windshield defrosting.
 


y If the vehicle has been parked in direct
sunlight during hot weather, open the
windows to let warm air escape, then
run the climate control system.
 


y Run the air conditioner about 10 minutes
at least once a month to keep internal
parts lubricated.
 


y Have the air conditioner checked before
the weather gets hot. Lack of refrigerant
may make the air conditioner less
effi cient.

 The refrigerant specifi cations are
indicated on a label attached to the
inside of the engine compartment. Check
the label before refi lling the refrigerant.
If the wrong type of refrigerant is used,
it could result in a serious malfunction
of the air conditioner.
  For details, consult an Authorized
Mazda Dealer.

illuminated or fl ashing (page 4-21 ).
The air conditioner may cause engine
overheating. If the warning light is
illuminated or fl ashing, turn the air
conditioning off (page 7-19 ).
NOTE




y When maximum cooling is desired,
set the temperature control dial to the
extreme cold position and set the air
intake selector to the recirculated air
mode, then turn the fan control dial
fully clockwise.
 


y If warmer air is desired at fl oor level,
set the mode selector dial at the
position and adjust the temperature
control dial to maintain maximum
comfort.
 


y The air to the fl oor is warmer than
air to the face (except when the
temperature control dial is set at the
extreme hot or cold position).
Ventilation
1. Set the mode selector dial to the
position.
2. Set the air intake selector to the outside
air mode.

position with the temperature
control set to the cold 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. Set
the temperature control to the hot or
warm position when using the

position.
NOTE
 


y For maximum defrosting, turn on the

WARNING
Always adjust the audio while the
vehicle is stopped:
Do not adjust the audio control
switches while driving the vehicle.
Adjusting the audio while driving
the vehicle is dangerous as it could
distract your attention from the vehicle
operation which could lead to a
serious accident.
Even if the audio control switches are
equipped on the steering wheel, learn
to use the switches without looking
down at them so that you can keep
your maximum attention on the road
while driving the vehicle.
CAUTION
For the purposes of safe driving,
adjust the audio volume to a level that
allows you to hear sounds outside of
the vehicle including car horns and
particularly emergency vehicle sirens.
NOTE
 


y To prevent the battery from being
discharged, do not leave the audio
system on for a long period of time
when the engine is not running.
 


y If a cellular phone or CB radio is used
in or near the vehicle, it could cause
noise to occur from the audio system,
however, this does not indicate that the
system has been damaged.
