Driving Tips
Form No. 8R09-EA-02G
•Carry emergency gear, including tire
chains, window scraper, flares, a small
shovel, jumper cables, and a small bag
of sand or salt.
Ask a Mazda dealer to perform the
following precautions:
• Have the proper ratio of antifreeze in
the radiator.
• Inspect the battery and its cables. Cold
reduces battery capacity.
• Use only cold-weather engine oil
(page 8-13).
• Inspect the ignition system for damage
and loose connections.
• Use washer fluid made with
antifreeze
—but don ’t use engine
coolant antifreeze for washer fluid
(page 8-22).
• Don
’t use the parking brake in freezing
weather as the parking brake may
freeze. Instead, shift to P with an
automatic transmission and to 1 or R
with a manual transmission. Block the
rear wheels.

Snow Tires
Use snow tires on all four wheels
Don
’t go faster than 120 km/h (75 mph).
Inflate snow tires 30 kPa (0.3 kgf/cm2, 4.3
psi) more than recommended on the tire
pressure label (driver ’s door), but never
more than the maximum cold-tire
pressure shown on the tires.
Your 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, you may find it necessary
to replace the original equipment tires
with snow tires, during the winter months.
Winter Driving
Mixing Tire Types:
Using tires different in size or type is
dangerous. Your vehicle’ s handling
could be greatly affected and result in
an accident. Use only the same size
and type tires (snow, radial, or non-
radial) on all four wheels.
Check local regulations before using
studded tires.

Tachometer
The tachometer shows engine speed in
thousands of revolutions per minute
(rpm).

Engine Coolant Temperature
Gauge
The engine coolant temperature gauge
shows the temperature of the engine
coolant.
If the needle exceeds normal range toward
H, it indicates overheating.
NOTE
• Only the trip meters record tenths of
kilometers (miles).
• The trip record will be erased when;

The power supply is interrupted
(blown fuse or the battery is
disconnected).
 The vehicle is driven over 999.9
km (mile).
Don ’t run the engine with the
tachometer needle in the RED ZONE.
This may cause severe engine damage.
Red zone
CAUTION
Driving with an overheated engine can
cause serious engine damage (page 7-
11).

Overheating
If the temperature gauge indicates
overheating, the vehicle loses power, or
you hear a loud knocking or pinging
noise, the engine is probably too hot.
If this happens:
1. Drive safely to the side of the road and park off the right-of-way.
2. Put a vehicle with an automatic transmission in park (P), a manual
transmission in neutral.
Apply the parking brake.
3. Turn off the air conditioner. 4. Check whether coolant or steam is
escaping from under the hood or from
the engine compartment.
If steam is coming from the engine
compartment:
Don ’t go near the front of the vehicle.
Stop the engine. Then turn the ignition
switch to the ON position without
starting the engine.
The radiator cooling fans will start to
cool the engine.
If neither coolant nor steam is
escaping:
Open the hood and idle the engine until
it cools. If this doesn ’t lower the
temperature, stop the engine and let it
cool.
5. Visually inspect the alternator/water pump drive belt for looseness and
breakage and all cooling hose
connections for leaks. If the belt is
broken or coolant is leaking, call an
Authorized Mazda Dealer for
assistance.
6. If the drive belt is OK, the engine is cool, and no coolant leaks are obvious,
inspect the coolant level. Carefully add
coolant as required (page 8-15).
Overheating
Steam from Overheated Engine:
Steam from an overheated engine is
dangerous. The escaping steam could
seriously burn you. Open the hood
ONLY after steam is no longer
escaping from the engine.

In Case of an Emergency
Overheating
Form No. 8R09-EA-02G
Cooling System Cap:
When the engine and radiator are
hot, scalding coolant and steam may
shoot out under pressure and cause
serious injury. Don’t remove the
cooling system cap when the engine
and radiator are hot.
If the engine continues to overheat or
frequently overheats, have the cooling
system inspected. The engine could be
seriously damaged unless repairs are
made.
