SERVICE RECOMMENDATIONS
To help you service your vehicle:
• We highlight do-it-yourself items in the engine compartment for easy
location.
• We provide a Scheduled Maintenance section which makes tracking
routine service easy.
If your vehicle requires professional service, your dealership can provide
necessary parts and service. Check your “Warranty Information” to find
out which parts and services are covered.
Use only recommended fuels, lubricants, fluids and service parts
conforming to specifications. Genuine Mazda parts are designed and built
to provide the best performance in your vehicle.
PRECAUTIONS WHEN SERVICING YOUR VEHICLE
• Do not work on a hot engine.
• Make sure that nothing gets caught in moving parts.
• Do not work on a vehicle with the engine running in an enclosed
space, unless you are sure you have enough ventilation.
• Keep all open flames and other lit material away from the battery and
all fuel related parts.
Working with the engine off
• Automatic transmission:
1. Set the parking brake and shift to P (Park).
2. Turn off the engine and remove the key.
3. Block the wheels.
• Manual transmission:
1. Set the parking brake, depress the clutch and place the gearshift in 1 (First).
2. Turn off the engine and remove the key.
3. Block the wheels.

4. To install the cap, align the tabs on the cap with the notches on thefiller pipe.
5. Turn the filler cap clockwise 1/8 of a turn until it stops.
“Check Fuel Cap” illuminates when the ignition is turned to the ON
position to ensure your bulb is working. When this light turns on, check
the fuel filler cap. Continuing to operate the vehicle with the Check Fuel
Cap light on, can activate the Service Engine Soon warning. When the
fuel filler cap is properly re-installed, the light(s) will turn off after a
period of normal driving. It may take a long period of time for the
system to detect an improperly installed fuel filler cap.
If you must replace the fuel filler cap, replace it with a fuel filler
cap that is designed for your vehicle. The warranty may be void
for any damage to the fuel tank or fuel system if the correct
genuine Mazda fuel filler cap is not used.
WARNING: The fuel system may be under pressure. If the fuel
filler cap is venting vapor or if you hear a hissing sound, wait
until it stops before completely removing the fuel filler cap.
Otherwise, fuel may spray out and injure you or others.
WARNING: If you do not use the proper fuel filler cap,
excessive pressure or vacuum in the fuel tank may damage the
fuel system or cause the fuel cap to disengage in a collision,
which may result in possible personal injury.
Choosing the right fuel
Use only UNLEADED FUEL. The use of leaded fuel is prohibited by law
and could damage your vehicle.
If your vehicle is a flexible fuel vehicle (FFV), use only UNLEADED
FUEL and (E85) ETHANOL. The use of leaded fuel is prohibited by law
and could damage your vehicle.
Do not use fuel containing methanol. It can damage critical fuel system
components.
Your vehicle was not designed to use fuel or fuel additives with metallic
compounds, including manganese-based compounds containing MMT.
Repairs to correct the effects of using a fuel for which your vehicle was
not designed may not be covered by your warranty.

•Revving the engine before turning it off may reduce fuel economy.
• Using the air conditioner or defroster may reduce fuel economy.
• You may want to turn off the speed control in hilly terrain if
unnecessary shifting between third and fourth gear occurs.
Unnecessary shifting of this type could result in reduced fuel
economy.
• Warming up a vehicle on cold mornings is not required and may
reduce fuel economy.
• Resting your foot on the brake pedal while driving may reduce fuel
economy.
• Combine errands and minimize stop-and-go driving.
Maintenance
• Keep tires properly inflated and use only recommended size.
• Operating a vehicle with the wheels out of alignment will reduce fuel
economy.
• Use recommended engine oil. Refer to Lubricant specificationsin
this chapter.
• Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found in your vehicle service maintenance section.
Conditions
• Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
• Carrying unnecessary weight may reduce fuel economy (approximately
0.4 km/L [1 mpg] is lost for every 180 kg [400 lb] of weight carried).
• Adding certain accessories to your vehicle (for example bug
deflectors, rollbars/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
• Using fuel blended with alcohol may lower fuel economy.
• Fuel economy may decrease with lower temperatures during the first
12–16 km (8–10 miles) of driving.
• Driving on flat terrain offers improved fuel economy as compared to
driving on hilly terrain.
• Transmissions give their best fuel economy when operated in the top
cruise gear and with steady pressure on the gas pedal.

•Four-wheel-drive operation (if equipped) is less fuel efficient than
two-wheel-drive operation.
• Close windows for high speed driving.
EPA window sticker
Every new vehicle should have the EPA window sticker. Contact your
dealer if the window sticker is not supplied with your vehicle. The EPA
window sticker should be your guide for the fuel economy comparisons
with other vehicles.
It is important to note the box in the lower left corner of the window
sticker. These numbers represent the Range of L/100 km (MPG)
expected on the vehicle under optimum conditions. Your fuel economy
may vary depending upon the method of operation and conditions.
EMISSION CONTROL SYSTEM
Your vehicle is equipped with various emission control components and a
catalytic converter which will enable your vehicle to comply with
applicable exhaust emission standards. To make sure that the catalytic
converter and other emission control components continue to work
properly:
• Use only the specified fuel listed.
• Avoid running out of fuel.
• Do not turn off the ignition while your vehicle is moving, especially at
high speeds.
• Have the items listed in your service maintenance section performed
according to the specified schedule.
The scheduled maintenance items listed in the scheduled maintenance
section are essential to the life and performance of your vehicle and to
its emissions system.
If other than Mazda authorized parts are used for maintenance
replacements or for service of components affecting emission control,
such non-Mazda parts should be equivalent to genuine Mazda parts in
performance and durability.
WARNING: Do not park, idle, or drive your vehicle in dry grass
or other dry ground cover. The emission system heats up the
engine compartment and exhaust system, which can start a fire.
Illumination of the
CHECK
ENGINEindicator, charging system warning light or the
temperature warning light, fluid leaks, strange odors, smoke or loss of
engine power, could indicate that the emission control system is not
working properly.

WARNING: Exhaust leaks may result in entry of harmful and
potentially lethal fumes into the passenger compartment.
Do not make any unauthorized changes to your vehicle or engine. By
law, vehicle owners and anyone who manufactures, repairs, services,
sells, leases, trades vehicles, or supervises a fleet of vehicles are not
permitted to intentionally remove an emission control device or prevent
it from working. Information about your vehicle’s emission system is on
the Vehicle Emission Control Information Decal located on or near the
engine. This decal identifies engine displacement and gives some tune up
specifications.
Please consult your “Warranty Information” for complete emission
warranty information.
Readiness for Inspection/Maintenance (I/M) testing
In some localities, it may be a legal requirement to pass an I/M test of
the on-board diagnostics system. If your “Check Engine/Service Engine
Soon” light is on, refer to the description in the Warning lights and
chimes section of the Instrument cluster chapter. Your vehicle may not
pass the I/M test with the “Check Engine/Service Engine Soon” light on.
If the vehicle’s powertrain system or its battery has just been serviced,
the on-board diagnostics system is reset to a “not ready for I/M test”
condition. To ready the on-board diagnostics system for I/M testing, a
minimum of 30 minutes of city and highway driving is necessary as
described below:
• First, at least 10 minutes of driving on an expressway or highway.
• Next, at least 20 minutes driving in stop-and-go, city-type traffic with
at least four idle periods.
Allow the vehicle to sit for at least eight hours without starting the
engine. Then, start the engine and complete the above driving cycle. The
engine must warm up to its normal operating temperature. Once started,
do not turn off the engine until the above driving cycle is complete.
