Saving Fuel and
Protection of the Environment
▼ Saving Fuel and Protection of the
Environment
How you operate your Mazda
determines how far it will travel on a
tank of fuel. Use these suggestions to
help save fuel and reduce CO
2.
Avoid long warm-ups. Once the
engine runs smoothly, begin driving.
Avoid fast starts.Drive at lower speeds.Anticipate when to apply the brakes
(avoid sudden braking).
Follow the maintenance schedule
and have an Authorized Mazda
Dealer perform inspections and
servicing.
Refer to Scheduled Maintenance
(U.S.A. and Puerto Rico) on page
6-4.
Refer to Scheduled Maintenance
(Canada) on page 6-6.

Winter Driving
▼Winter Driving
Carry emergency gear, including tire
chains, window scraper,
flares, a small
shovel, jumper cables, and a small bag
of sand or salt.
Ask an Authorized Mazda Dealer to
check the following:
Have the proper ratio of antifreeze in
the radiator.
Refer to Engine Coolant on page
6-20.
Inspect the battery and its cables.
Cold reduces battery capacity.
Use an engine oil appropriate for the
lowest ambient temperatures that
the vehicle will be driven in (page
6-17).
Inspect the ignition system for
damage and loose connections.
Use washer fluid made with
antifreeze ―but do not use engine
coolant antifreeze for washer fluid
(page 6-22).
NOTE
Remove snow before driving. Snow
left on the windshield is dangerous
as it could obstruct vision.
Do not apply excessive force to a
window scraper when removing ice
or frozen snow on the mirror glass
and windshield.
Never use warm or hot water for
removing snow or ice from windows
and mirrors as it could result in the
glass cracking.
Drive slowly. Braking performance
can be adversely a ffected if snow or
ice adheres to the brake
components. If this situation occurs,
drive the vehicle slowly, releasing the
accelerator pedal and lightly applying
the brakes several times until the
brake performance returns to
normal.
▼ Snow Tires
Use snow tires on all 4 wheels
Do not go faster than 120 km/h (75
mph) while driving with snow tires.
In
flate snow tires 30 kPa (0.3 kgf/cm
2,
4.3 psi) more than recommended on
the tire pressure label (driver's door
frame), but never more than the
maximum cold-tire pressure shown on
the tires.

Mexico
The vehicle is originally equipped with
summer tires designed for optimum
traction on wet and dry roads. If your
vehicle is to be used on snow and ice
covered roads, Mazda recommends
that you replace the tires originally
equipped on your vehicle with snow
tires during the winter months.
Except Mexico
The vehicle is originally equipped with
all season radials designed to be used
all year around. In some extreme
climates you may find it necessary to
replace them with snow tires during
the winter months to further improve
traction on snow and ice covered
roads.

Operating Tips
▼Operating Tips
Operate the climate control system
with the engine running.
To prevent the battery from being
discharged, do not leave the fan
control switch on for a long period of
time with the ignition switched ON
when the engine is not running.
Clear all obstructions such as leaves,
snow and ice from the hood and the
air inlet in the cowl grille to improve
the system e
fficiency.
Use the climate control system to
defog the windows and dehumidify
the air.
The recirculate mode should be used
when driving through tunnels or
while in a
traffic jam, or when you
would like to shut o ff outside air for
quick cooling of the interior.
Use the outside air position for
ventilation or windshield defrosting.
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.
(With A/C switch)
Run the air conditioner about 10
minutes at least once a month to
keep internal parts lubricated.
Have the air conditioner checked
before the weather gets hot. Lack of
refrigerant may make the air
conditioner less e fficient.
The refrigerant specifications are
indicated on a label attached to the
inside of the engine compartment. If
the wrong type of refrigerant is used,
it could result in a serious
malfunction of the air conditioner.
Consult a professional, government certi fied repairer for the inspection
or repair because a special device is
required for the air conditioner
maintenance.
For details, consult an Authorized
Mazda Dealer.
