Before Driving Your Mazda
Driving Tips
Form No. 8R21-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 8-9).
•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 8-16).
•Don’t use the parking brake in freezing
weather as the parking brake may
freeze. Instead, shift to P and 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), but never
more than the maximum cold-tire
pressure shown on the tires.
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.

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. Shift into park (P).
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. 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 8-11).
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.

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.

Maintenance and Care

Check the oil level and fill to the MAX
mark if necessary.
Oil capacity (General reference only,
refer to Specifications section for
capacities.)
Changing oil filter
Because you need a special tool to
retighten the filter, an Authorized Mazda
Dealer should do the work.

Inspecting Coolant Level
Inspect the antifreeze protection and
coolant level in the coolant reservoir at
least once a year—at the beginning of the
winter season—and before traveling
where temperatures may drop below
freezing.
Inspect the condition and connections of
all cooling system and heater hoses.
Replace any that are swollen or
deteriorated.
The coolant should be at full in the
radiator and between the F and L marks
on the coolant reservoir when the engine
is cool.
NOTE
•The indicated engine oil capacities
are for general reference purposes
only. When adding or changing oil,
verify the engine oil level with the
oil dipstick.
•Use only specified engine oil (page
10-4).
Engine Coolant
Hot Engine:
A hot engine is dangerous. If the
engine has been running, parts of the
engine compartment can become very
hot. You could be burned. Don’t
inspect the coolant system or add
coolant when the engine is hot.

If it’s at or near L, add enough coolant to
the coolant reservoir to provide freezing
and corrosion protection and to bring the
level to F.
Do not overfill.
If new coolant is required frequently,
consult an Authorized Mazda Dealer.

Changing Coolant (Without Rear
Heater)
Change coolant according to Scheduled
Maintenance (page 8-3).For mixture percentage:
To change coolant
1. Remove the cooling system cap. Radiator coolant will damage paint.
Rinse it off quickly.
•Use only soft (demineralized) water
in the coolant mixture. Water that
contains minerals will cut down on
the coolant’s effectiveness.
•Don’t add only water. Always add a
proper coolant mixture.
•The engine has aluminum parts and
must be protected by an ethylene-
glycol-based coolant to prevent
corrosion and freezing.
•DO NOT USE alcohol or methanol
antifreeze. DO NOT MIX alcohol
or methanol with the coolant. This
could damage the cooling system.
•Don’t use a solution that contains
more than 60 % antifreeze.
This would reduce effectiveness.

Removing the Cooling System Cap:
Removing the cooling system cap or
drain plug while the engine is
running or hot is dangerous. This
might lead to cooling system and
engine damage and could result in
serious injury from escaping hot
coolant or steam. Turn off the engine
and wait until it’s cool. Even then, be
very careful when removing the cap
or drain plug. Wrap a thick cloth
around it and slowly turn it
counterclockwise to the first stop.
Step back while the pressure escapes.
When you’re sure all the pressure is
gone, press down on the cap—still
using a cloth—turn the cap, and
remove it.

2. Only when the engine is cool, remove
the radiator drain plug and drain the
coolant into a suitable container.
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.

Changing Coolant (With Rear
Heater)
Have an Authorized Mazda Dealer change
the coolant according to the Scheduled
Maintenance (page 8-3).

Inspecting Brake Fluid Level
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 linings. If it
is excessively low, have the brake system
inspected by an Authorized Mazda
Dealer.
