Operating Tips
lOperate the climate control system
with the engine running.
lTo 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.
lClear all obstructions such as leaves,
snow and ice from the hood and the air
inlet in the cowl grille to improve the
system efficiency.
lUse the climate control system to defog
the windows and dehumidify the air.
lThe recirculate mode should be used
when driving through tunnels or while
in a traffic jam, or when you would like
to shut off outside air for quick cooling
of the interior.
lUse the outside air position for
ventilation or windshield defrosting.
lIf 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.
lRun the air conditioner about 10
minutes at least once a month to keep
internal parts lubricated.
lHave the air conditioner checked
before the weather gets hot. Lack of
refrigerant may make the air
conditioner less efficient.
The refrigerant specifications are
indicated on a label attached to the
inside of the engine compartment.
Check the label before refilling 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.

Overheating
If the High engine coolant temperature
warning light illuminates, the vehicle
loses power, or you hear a loud knocking
or pinging noise, the engine is probably
too hot.
WARNING
Switch the ignition to off and
make sure the fan is not running before
attempting to work near the cooling
fan:
Working near the cooling fan when it
is running is dangerous. The fan
could continue running indefinitely
even if the engine has stopped and
the engine compartment temperature
is high. You could be hit by the fan
and seriously injured.
Do not remove either
cooling system cap when the engine
and radiator are hot:
When the engine and radiator are
hot, scalding coolant and steam may
shoot out under pressure and cause
serious injury.
Open the hood ONLY after steam is no
longer escaping from the engine:
Steam from an overheated engine is
dangerous. The escaping steam could
seriously burn you.
If the High engine coolant temperature
warning light illuminates:
1. Drive safely to the side of the road and
park off the right-of-way.2. Put a vehicle with an automatic
transaxle in park (P), a manual
transaxle in neutral.
3. Apply the parking brake.
4. Turn off the air conditioner.
5. Check whether coolant or steam is
escaping from the engine compartment.
If steam is coming from the engine
compartment:
Do not go near the front of the vehicle.
Stop the engine.
Wait until the steam dissipates, then
open the hood and start the engine.
If neither coolant nor steam is
escaping:
Open the hood and idle the engine until
it cools.
CAUTION
If the cooling fan does not operate
while the engine is running, the
engine temperature will increase.
Stop the engine and call an
Authorized Mazda Dealer.
6. Make sure the cooling fan is operating,
then turn off the engine after the
temperature has decreased.
7. When cool, check the coolant level.
If it is low, look for coolant leaks from
the radiator and hoses.

qIf the brake system warning light
illuminates
When the light turns on
If the brake system warning light remains
turned on even though the electric parking
brake is released, the brake fluid may be
low or there could be a problem with the
brake system. Park the vehicle in a safe
place immediately and contact an
Authorized Mazda Dealer.
When the light is flashing
The light flashes if the electric parking
brake has a malfunction.
If the light remains flashing even if the
electric parking brake switch is operated,
consult an Authorized Mazda Dealer as
soon as possible.
WARNING
Do not drive with the brake system
warning light illuminated. Contact an
Authorized Mazda Dealer to have the
brakes inspected as soon as possible:
Driving with the brake system
warning light illuminated is
dangerous. It indicates that your
brakes may not work at all or that
they could completely fail at any
time. If this light remains
illuminated, after checking that the
parking brake is fully released, have
the brakes inspected immediately.
CAUTION
In addition, the effectiveness of the
braking may diminish so you may
need to depress the brake pedal more
strongly than normal to stop the
vehicle.
qIf the ABS warning light illuminates
If the ABS warning light stays on while
you're driving, the ABS control unit has
detected a system malfunction. If this
occurs, your brakes will function normally
as if the vehicle had no ABS.
Should this happen, consult an Authorized
Mazda Dealer as soon as possible.
NOTE
lWhen the engine is jump-started to charge
the battery, uneven rpm occurs and the ABS
warning light may illuminate. If this occurs,
it is the result of the weak battery and does
not indicate an ABS malfunction.
Recharge the battery.
lThe brake assist system does not operate
while the ABS warning light is illuminated.
