Before Driving Your Mazda
Driving Tips
Form No. 8R29-EA-02I
•
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
8-10).
•
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 8-19).
•
Don’t use the parking brake in freezing
weather as the parking brake may
freeze. Instead, shift to P with an
automatic transaxle and to 1 or R with
a manual transaxle. Block the rear
wheels.

Snow Tires
Use snow tires on all four wheels
Your 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.
Don’t go faster than 120 km/h (75 mph).
Inflate 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.

Tire Chains
This vehicle cannot be operated with tire
chains because it could cause interference
with the vehicle body and scratching.
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.
WARNING
Check local regulations before using
studded tires.

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
transaxle in park (P), a manual
transaxle 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.
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.

5. Check the coolant level.
If it’s low, look for leaks in the radiator
hoses and connections, heater hoses
and connections, radiator, and water
pump.
If you find a leak or other damage, or if
coolant is still leaking, stop the engine
and call an Authorized Mazda Dealer.
If you find no problems, the engine is
cool, and no leaks are obvious, carefully
add coolant as required (page 8-13).

Cooling System Caps:When the engine and radiator are
hot, scalding coolant and steam may
shoot out under pressure and cause
serious injury. Don’t remove either
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.

2. Only when the engine is cool, remove
the radiator drain plug and drain the
coolant into a suitable container.
Properly dispose of the used coolant.
3. Flush out the system with running
water.
4. Drain the system completely. Insert
and tighten the plug. Add as much
ethylene-glycol-based coolant and
water as necessary to provide freezing
and corrosion protection.
5. In extremely cold climates, add the
amount recommended in the coolant
manufacturer’s instructions.
6. Run the engine at idle with the cooling
system cap off. Slowly add additional
coolant if necessary.
7. At this point, wait until the engine
reaches normal operating temperature;
then depress the accelerator two or
three times. Add more coolant, if
necessary, until the system is full.
8. Install the cooling system cap. Inspect
all connections for leaks. Inspect the
level in the coolant reservoir one more
time.

Inspecting Brake/Clutch Fluid
Level
The brakes and clutch draw fluid from the
same reservoir.
Inspect the fluid level in the reservoir
regularly. It should be kept at MAX.
The level normally drops with
accumulated distance, a condition
associated with wear of brake and clutch
linings. If it is excessively low, have the
brake/clutch system inspected by an
Authorized Mazda Dealer.
