WARNING: If you ever smell exhaust fumes of any kind inside
your vehicle, have your authorized Mazda dealer inspect and fix
your vehicle immediately. Do not drive if you smell exhaust
fumes. These fumes are harmful and result in accident or death.
Have the exhaust and body ventilation systems checked whenever:
• the vehicle is raised for service.
• the sound of the exhaust system changes.
• the vehicle has been damaged in a collision.
WARNING: Engine exhaust, some of its constituents, and
certain vehicle components contain or emit chemicals known to
the State of California to cause cancer and birth defects or
other reproductive harm. In addition, certain fluids contained in
vehicles and certain products of component wear contain or
emit chemicals known to the State of California to cause cancer
and birth defects or other reproductive harm.
Important ventilating information
If the engine is idling while the vehicle is stopped in an open area for
long periods of time, open the windows at least 2.5 cm (one inch).
Adjust the heating or air conditioning (if equipped) to bring in fresh air.
Note: Improve vehicle ventilation by
keeping all air inlet vents clear of
snow, leaves and other debris.
BRAKES
Your service brakes are self-adjusting. Refer to the service maintenance
section for scheduled maintenance.
Occasional brake noise is normal and often does not indicate a
performance concern with the vehicle’s brake system. In normal
operation, automotive brake systems may emit occasional or intermittent

INTRODUCTION
Be extremely careful to prevent injury to yourself and others and
damage to your vehicle when using this manual for inspection and
maintenance.
If you’re unsure about any procedure it describes, we strongly urge you
to have a reliable and qualified service shop perform the work, preferably
an Authorized Mazda Dealer.
Factory-trained Mazda technicians and genuine Mazda parts are best for
your vehicle. Without this expertise and the parts that have been
designed and made especially for your Mazda, inadequate, incomplete,
and insufficient servicing may result in problems. This could lead to
vehicle damage or an accident and injuries.
For expert advice and quality service, consult an Authorized Mazda
Dealer.
The owner should retain evidence that proper maintenance has been
performed as prescribed.
A claim against a warranty will not qualify if it results from lack of
maintenance and not from defective material or authorized Mazda
workmanship.
Any auto repair shop using parts equivalent to your Mazda’s original
equipment may perform maintenance.But we recommend that it
always be done by an Authorized Mazda Dealer using genuine
Mazda parts.
SCHEDULED MAINTENANCE
Schedule I – Normal Driving Conditions/Emission Control
Systems
Follow Schedule I if the vehicle is operated mainly where none of the
following conditions apply. If any do apply follow Schedule II.
• Repeated short-distance driving.
• Driving in dusty conditions.
• Towing a trailer.
• Operating in hot weather in stop-and-go “rush hour” traffic.
• Extended periods of idling or low-speed operation.
• High-speed operation with a fully loaded vehicle.
• Off-road operation.
NOTE:After the described period, continue to follow the described
maintenance at the recommended intervals.
Maintenance and Specifications

5. The California Air Resources Board has determined that the failureto perform this maintenance item will not nullify the emission
warranty nor limit recall liability prior to completion of the vehicle’s
useful life.
SCHEDULE II – SPECIAL OPERATING CONDITIONS
If your driving habits FREQUENTLYinclude one or more of the
following conditions:
• Short trips of lessthan 16 km (10 miles) when outside temperatures
remain below freezing.
• Towing a trailer, or carrying maximum loads.
• Operating in severe dust conditions.
• Operating during hot weatherin stop-and-go “rush-hour” traffic.
• Extensive idling, such as police, taxi or door-to-door delivery service.
• High speed operation with a fully loaded vehicle (max. GVW).
• Off-road operation.
Change ENGINE OIL AND OIL FILTER every 3 months or 4,800 km
(3,000 miles) whichever occurs first.
NOTE: Idling the engine for extended periods will accumulate more
hours of use on your vehicle than is actually indicated by the mileage
odometer. Consequently, the odometer reading can be often misleading
when determining the right time to change your engine oil and filter. If
you are using your vehicle in a manner which allows it to remain
stationary while the engine is running for long periods (door-to-door
delivery, taxi, police, power/utility company trucks, or similar duty), then
Mazda recommends you increase the frequency of oil and filter changes
to an interval equivalent to 200 ENGINE HOURS of use. Since most
vehicles are not equipped with hour-meters, it may be necessary for you
to approximate your idle time and plan oil/filter changes accordingly.

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
Be especially careful when inspecting or servicing your vehicle.
• Do not work on a hot engine.
• When the engine is running, make sure that loose clothing, jewelry or
long hair does not get caught up 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 lit cigarettes, open flames and other lit material away from
the battery and all fuel related parts.
If you disconnect the battery, the engine must “relearn” its idle
conditions before your vehicle will drive properly, as explained in the
Battery section of this chapter.
Working with the engine off
• Automatic transmission:
1. Set the parking brake and ensure the gearshift is securely latched in P (Park).
2. Turn off the engine and remove the key.
3. Block the wheels to prevent the vehicle from moving unexpectedly.
