Fuel and Engine Exhaust Precautions
Vehicles with catalytic converters or oxygen sensors must use ONLY UNLEADED FUEL, 
which will reduce exhaust emissions and keep spark plug fouling to a minimum.
Your Mazda will perform best with fuel listed in the table.
*U.S. federal law requires that octane ratings be posted on gasoline station pumps.
Fuel with a rating lower than 87 octane (91 RON) could cause the emission control 
system to lose effectiveness. It could also cause engine knocking and serious engine 
damage.
Gasoline blended with oxygenates such as alcohol or ether compounds are generally 
referred to as oxygenated fuels. The common gasoline blend that can be used with your 
vehicle is ethanol blended at no more than 10%. Gasoline containing alcohol, such as 
ethanol or methanol, may be marketed under the name "Gasohol".
Vehicle damage and drivability problems resulting from the use of the following may not 
be covered by the Mazda warranty.
• Gasohol containing more than 10% ethanol.
• Gasoline or gasohol containing methanol.
• Leaded fuel or leaded gasohol.
Fuel Requirements
Fuel
Octane Rating* (Anti-knock index)
Regular unleaded fuel 87 [ (R+M)/2 method] or above (91 RON or above)
•USE ONLY UNLEADED FUEL.
Leaded fuel is harmful to the catalytic converter or the oxygen sensor. The lead will 
accumulate on the oxygen sensor and the catalyst inside the converter. This will result 
in a malfunction of the emission control system, causing poor performance.
• Your vehicle can only use oxygenated fuels containing no more than 10% ethanol by 
volume. Damage to your vehicle may occur when ethanol exceeds this 
recommendation, or if the gasoline contains any methanol. Stop using gasohol of any 
kind if your vehicle engine is performing poorly.
• Never add fuel system additives. Never add cleaning agents other than those specified 
by Mazda. Other cleaning agents and additives may damage the system. Consult an 
Authorized Mazda Dealer.

Before Driving Your Mazda
Fuel and Engine Exhaust Precautions
Form No. 8S18-EA-03I
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.
Emission Control System
Parking Over Flammable Objects:
Parking over or near anything flammable, such as dry grass, is dangerous. Even with 
the engine turned off, the exhaust system could ignite it because the exhaust system 
gets very hot during normal use. A resulting fire could cause serious injury or death. 
Never park over or near anything flammable.
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.
•USE ONLY UNLEADED FUEL.
• Don
’t drive your Mazda with any sign of engine malfunction.
• Don
’t coast with the ignition switch turned off.
• Don
’t descend steep grades in gear with the ignition switch turned off.
• Don
’t operate the engine at high idle for more than 5 minutes.
• Don
’t tamper with the emission control system. All inspections and adjustments must 
be made by a qualified technician.
• Don
’t try to 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
After driving some distance and turning off the engine, 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 after 
turning off the engine.

Fuel and Engine Exhaust Precautions
Form No. 8S18-EA-03I
Engine Exhaust (Carbon Monoxide)
Carbon Monoxide:
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.
Exhaust Gas in 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. Don’t run the engine when inside an 
enclosed area.
Idling with the Windows Closed:
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. Open the windows or adjust the heating or cooling system to draw 
fresh air.
Snow Blocking the Exhaust Gas:
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, anyone in the cabin could be 
injured or killed. Clear the snow from underneath and around your vehicle, 
particularly the tail pipe, before starting the engine.

Driving Tips
No special break-in is necessary, but a few 
precautions in the first 1,000 km (600 
miles) may add to the performance, 
economy, and life of your Mazda.
•Don
’t race the engine.
• Don
’t maintain one constant speed, 
either slow or fast, for a long period of 
time.
• Don
’t drive constantly at full-throttle or 
high engine rpm for extended periods 
of time.
• Avoid unnecessary hard stops.
• Avoid full-throttle starts. How you operate your Mazda determines 
how far it will travel on a tank of fuel. Use 
these suggestions to help save money on 
fuel and repairs.
•
Avoid long warm-ups. Once the engine 
runs smoothly, begin driving.
• Avoid fast starts.
• Keep the engine tuned. Follow the 
maintenance schedule (page 8-3) and 
have an Authorized Mazda Dealer 
perform inspections and servicing.
• Use the air conditioner only when 
necessary.
• Slow down on rough roads.
• Keep the tires properly inflated.
• Don
’t carry unnecessary weight.
• Don
’t rest your foot on the brake pedal 
while driving.
• Keep the wheels in correct alignment.
• Keep windows closed at high speeds.
• Slow down when driving in crosswinds 
and headwinds.
Break-In PeriodMoney-Saving Suggestions
Coasting:
Stopping the engine when going down 
a hill is dangerous. This causes the 
loss of power steering and power 
brake control, and may cause damage 
to the drivetrain. Any loss of steering 
or braking control could cause an 
accident. Never stop the engine when 
going down a hill.

Driving Tips
Form No. 8S18-EA-03I
When driving on ice or in water, snow, 
mud, sand, or similar hazard:
•Be cautious and allow extra distance 
for braking.
• Avoid sudden braking and quick 
steering.
• If your vehicle is not equipped with 
ABS, brake with the pedal by using a 
light up-down motion. Don
’t hold the 
pedal down constantly.
If your vehicle is equipped with ABS, 
don ’t pump the brakes. Continue to 
press down on the brake pedal.
• If you get stuck, select a lower gear and 
accelerate slowly. Don
’t spin the front 
wheels.
• For 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.
Hazardous Driving
Downshifting 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. If it is 
necessary to downshift on slippery 
surfaces, be very careful.
WARNING
NOTE
Use snow chains only on the front 
wheels.

Driving Tips
Form No. 8S18-EA-03I
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.•
Carry 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:
• Have the proper ratio of antifreeze in 
the radiator.
• Inspect the battery and its cables. Cold 
reduces battery capacity.
• 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 8-21).
• 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.
Rocking the Vehicle
Spinning the Wheels:
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. Don ’t spin the wheels at 
more than 56 km/h (35 mph), and 
don ’t allow anyone to stand behind a 
wheel when pushing the vehicle.
Too much rocking may cause engine 
overheating, transaxle failure, and tire 
damage.

Snow Tires
Use snow tires on all four wheels
Don
’t 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), but never 
more than the maximum cold-tire 
pressure shown on the tires. Except Brazil
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.
Brazil
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.
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.
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 5-24).
