MAZDA MODEL 3 HATCHBACK 2012 Owners Manual (in English)

Black plate (150,1)
Emission Control System
Your vehicle is equipped with an emission control system (the catalytic converter is part of
this system) that enables your vehicle to comply with existing exhaust emissions
requirements.
WARNING
Never park over or near anything flammable:Parking over or near anything flammable, such as dry grass, is dangerous. Even with
the engine turned off, the exhaust system remains very hot after normal use and
could ignite anything flammable. A resulting fire could cause serious injury or death.
CAUTION
Ignoring the following precautions could cause lead to accumulate on the catalyst
inside the converter or cause the converter to get very hot. Either condition will
damage the converter and cause poor performance.
ØUSE ONLY UNLEADED FUEL.
Ø Do not drive your Mazda with any sign of engine malfunction.
Ø Do not coast with the ignition switched off.
Ø Do not descend steep grades in gear with the ignition switched off.
Ø Do not operate the engine at high idle for more than 2 minutes.
Ø Do not tamper with the emission control system. All inspections and adjustments
must be made by a qualified technician.
Ø Do not push-start or pull-start your vehicle.
NOTE
Under U.S. federal law, any modification to the original-equipment emission control system before
the first sale and registration of a vehicle is subject to penalties. In some states, such modification
made on a used vehicle is also subject to penalties.
NOTE
While the engine is off, the sound of a valve opening and closing can be heard at the rear of the right
side of the vehicle, however this does not indicate an abnormality. Your vehicle has a self-checking
device and it operates while the engine is off.

Engine Exhaust (Carbon Monoxide)
WARNING
Do not drive your vehicle if you smell exhaust gas inside the vehicle:Engine exhaust gas is dangerous. This gas contains carbon monoxide (CO), which is
colorless, odorless, and poisonous. When inhaled, it can cause loss of consciousness
and death. If you smell exhaust gas inside your vehicle, keep all windows fully open
and contact an Authorized Mazda Dealer immediately.
Do not run the engine when inside an enclosed area: Running the engine inside an enclosed area, such as a garage, is dangerous. Exhaust
gas, which contains poisonous carbon monoxide, could easily enter the cabin. Loss
of consciousness or even death could occur.
Open the windows or adjust the heating or cooling system to draw fresh air when
idling the engine: Exhaust gas is dangerous. When your vehicle is stopped with the windows closed
and the engine running for a long time even in an open area, exhaust gas, which
contains poisonous carbon monoxide, could enter the cabin. Loss of consciousness or
even death could occur.
Clear snow from underneath and around your vehicle, particularly the tail pipe,
before starting the engine: Running the engine when a vehicle is stopped in deep snow is dangerous. The
exhaust pipe could be blocked by the snow, allowing exhaust gas to enter the cabin.
Because exhaust gas contains poisonous carbon monoxide, it could cause loss of
consciousness or even death to occupants in the cabin.

Hazardous Driving
WARNING
Be extremely careful if it is necessary to
downshift on slippery surfaces:Downshifting into lower gear while
driving on slippery surfaces is
dangerous. The sudden change in tire
speed could cause the tires to skid.
This could lead to loss of vehicle
control and an accident.
Do not rely on ABS as a substitute for
safe driving: The ABS cannot compensate for
unsafe and reckless driving, excessive
speed, tailgating (following another
vehicle too closely), driving on ice and
snow, and hydroplaning (reduced tire
friction and road contact because of
water on the road surface). You can
still have an accident.
When driving on ice or in water, snow,
mud, sand, or similar hazards:
lBe cautious and allow extra distance
for braking.
lAvoid sudden braking and sudden
maneuvering.
lDo not pump the brakes. Continue to
press down on the brake pedal.
Refer to Anti-Lock Brake System
(ABS) on page 5-8.
lIf you get stuck, select a lower gear and
accelerate slowly. Do not spin the front
wheels.
lFor more traction in starting on
slippery surfaces such as ice or packed
snow, use sand, rock salt, chains,
carpeting, or other nonslip material
under the front wheels.
NOTE
Use snow chains only on the front wheels.
Floor Mat
WARNING
Make sure the floor mats are hooked
on the retention pins to prevent them
from bunching up under the foot
pedals: Using a floor mat that is not secured
is dangerous as it will interfere with
the accelerator and brake pedal
operation, which could result in an
accident.
Do not install two floor mats, one on
top of the other, on the driver's side: Installing two floor mats, one on top
of the other, on the driver's side is
dangerous as the retention pins can
only keep one floor mat from sliding
forward.
In using a heavy duty floor mat for
winter use always remove the
original floor mat.
Loose floor mat(s) will interfere with
the foot pedal and could result in an
accident.
When setting a floor mat, position the
floor mat so that its eyelets are inserted
over the pointed end of the retention
posts.

Rocking the Vehicle
WARNING
Do not spin the wheels at more than 56
km/h (35 mph), and do not allow
anyone to stand behind a wheel when
pushing the vehicle:When the vehicle is stuck, spinning
the wheels at high speed is
dangerous. The spinning tire could
overheat and explode. This could
cause serious injuries.
CAUTION
Too much rocking may cause engine
overheating, transaxle failure, and
tire damage.
If you must rock the vehicle to free it from
snow, sand or mud, depress the
accelerator slightly and slowly move the
shift lever from 1 (D) to R.
Winter Driving
lCarry 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
perform the following precautions:
lHave the proper ratio of antifreeze in
the radiator.
Refer to Engine Coolant on page 8-22.
lInspect the battery and its cables. Cold
reduces battery capacity.
lUse only cold-weather engine oil (page
8-19).
lInspect the ignition system for damage
and loose connections.
lUse washer fluid made with
antifreeze ―but do not use engine
coolant antifreeze for washer fluid
(page 8-27).
lDo not use the parking brake in
freezing weather as it may freeze.
Instead, shift to P with an automatic
transaxle and to 1 or R with a manual
transaxle. Block the rear wheels.
lDo not apply excessive force to a
window scraper when removing ice or
frozen snow on the mirror glass and
windshield.
lNever use warm or hot water for
removing snow or ice from windows
and mirrors as it could result in the
glass cracking.
lBraking performance can be adversely
affected if snow or ice adheres to the
brake equipment. 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.

qSnow Tires
Use snow tires on all four wheels
Do not go faster than 120 km/h (75 mph)
while driving with snow tires. 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.
SKYACTIV-G 2.0, MZR 2.0 and MZR
2.5
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.
MZR 2.3 DISI Turbo
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, Mazda recommends that
you replace the tires originally equipped
on your vehicle with snow tires during the
winter months.
WARNING
Use only the same size and type tires
(snow, radial, or non-radial) on all four
wheels: Using tires different in size or type is
dangerous. Your vehicle's handling
could be greatly affected and result
in an accident.
CAUTION
Check local regulations before using
studded tires. NOTE
If your vehicle is equipped with the tire
pressure monitoring system, the system may
not function correctly when using tires with
steel wire reinforcement in the sidewalls (page
5-35).
q
Tire Chains
Check local regulations before using tire
chains.
CAUTION
Ø Chains may affect handling.
Ø Do not go faster than 50 km/h (30
mph) or the chain manufacturer's
recommended limit, whichever is
lower.
Ø Drive carefully and avoid bumps,
holes, and sharp turns.
Ø Avoid locked-wheel braking.
Ø Do not use chains on a temporary
spare tire; it may result in damage
to the vehicle and to the tire.
Ø Do not use chains on roads that
are free of snow or ice. The tires
and chains could be damaged.
Ø Chains may scratch or chip
aluminum wheels.
NOTE
lUse of tire chains on a vehicle equipped
with P225/40R18 specification tires could
cause interference with the vehicle body
and scratching. If tire chains are to be used,
replace both front and rear tires with P
205/50R17 tires. Please consult an
Authorized Mazda Dealer.
lIf your vehicle is equipped with the tire
pressure monitoring system, the system may
not function correctly when using tire

Installing the chains
1. Remove the wheel covers, or the chainbands will scratch them.
2. Secure the chains on the front tires as tightly as possible. Always follow the
chain manufacturer's instructions.
3. Retighten the chains after driving 1/2 ―1 km (1/4 ―1/2 mile).
Driving In Flooded Area
WARNING
Dry wet brakes by driving very slowly
and applying the brakes lightly until
brake performance returns to normal:
Driving with wet brakes is
dangerous. Increased stopping
distance or the vehicle pulling to one
side when braking could result in a
serious accident. Light braking will
indicate whether the brakes have
been affected.
CAUTION
Do not drive the vehicle on flooded
roads as it could cause short
circuiting of electrical/electronic
parts, or engine damage or stalling
from water absorption. If the vehicle
has been immersed in water, consult
