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.

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.

Turbocharger Informationí
The turbocharger greatly enhances engine power. Its advanced design provides improved
operation and requires minimum additional maintenance. To get maximum performance
from your turbocharged engine, take note of the following tips:
lThe turbocharged engine is designed for optimal operation with premium unleaded
gasoline (page 4-2). Do not use fuel with a lower octane rating. Extra fuel additives are
NOT recommended.
lChange the engine oil and filter using the turbo engine interval outlined in the
maintenance schedule (for your driving condition).
lUse only the recommended engine oil (page 8-19). Extra oil additives are NOT
recommended.
lAfter driving at freeway speeds or up a long hill, idle the engine at least 30 seconds to
cool the turbo before turning off the engine. Avoid simply shutting the engine off
abruptly after a hard or long drive. Damage to the turbocharger may result.
lDo not race or over-rev the engine when starting. This should not be done with ANY
engine, especially not with one that's turbocharged.
lDo not add any aftermarket devices to alter the engine's ignition timing, fuel delivery, or
turbo boost pressure. This may lead to serious engine damage and may void your
warranty.

Ignition Switch
With advanced key
Refer to“Starting the engine (page 3-12) ”
for information on how to use the ignition
switch.
q Ignition Switch Positions
(Without Advanced Key)
The engraved mark on the actual vehicle
may read OFF or LOCK depending on the
type of ignition system.
OFF/LOCK
The power supply to electrical devices is
turned off. Only in this position can the
key be removed.
WARNING
Remove the key only when the vehicle
is parked (with steering lock
mechanism):
Removing the key from the ignition
switch while the vehicle is moving is
dangerous. Removing the key allows
the steering wheel to lock. You will
lose steering control and a serious
accident could occur.
Before leaving the driver's seat, always
switch the ignition off, set the parking
brake, and make sure the shift lever is
in P (automatic transaxle) or in 1st gear
or R (manual transaxle): Leaving the driver's seat without
switching the ignition off, setting the
parking brake, and shifting the shift
lever to P (automatic transaxle) or to
1st gear or R (manual transaxle) is
dangerous. Unexpected vehicle
movement could occur which could
result in an accident.
In addition, if your intention is to
leave the vehicle for even a short
period, it is important to switch the
ignition off, as leaving it in another
position will disable some of the
vehicle's security systems and run the
battery down.
NOTE
If turning the key is difficult, move the steering
wheel left and right.
Leaving the key in any position but the OFF/
LOCK position also disables some of the
security features and may run the battery
down.
ACC (Accessory)
In this position, some electrical
accessories will operate.
