²Replacement Parts and Accessories Limited Warranty
²Tire Warranty
NOTE:Detailed warranty information is provided with your Mazda.
OUTSIDE THE UNITED STATES AND CANADA
Government regulations in the United States require that automobiles
meet specific emission regulations and safety standards. Therefore,
vehicles built for use in the United States, its territories, and Canada may
differ from those sold in other countries.
The differences may make it difficult or even impossible for your vehicle
to receive satisfactory servicing in other countries. We strongly
recommend that you NOT take your Mazda outside these areas.
You may have these problems if you do:
²Recommended fuel may be unavailable. Any kind of leaded fuel or
low-octane fuel will affect vehicle performance and damage the
emission controls and engine.
²Proper repair facilities, tools, testing equipment, and replacement
parts may not be available.
The manufacturer's warranty applies only to Mazda vehicles registered
and normally operated in the United States, its territories, and Canada.
REPORTING SAFETY DEFECTS
If you believe that your vehicle has a defect which could cause a crash or
could cause injury or death, you should immediately inform the National
Highway Traffic Safety Administration (NHTSA) in addition to notifying
Mazda Motor Corporation (Your Mazda Importer/Distributor).
If NHTSA receives similar complaints, it may open an investigation, and
if it finds that a safety defect exists in a group of vehicles, it may order a
recall and remedy campaign. However NHTSA cannot become involved in
individual problems between you, your dealer, or Mazda Motor
Corporation (Your Mazda Importer/Distributor).
To contact NHTSA, you may either call the Auto Safety Hotline toll-free
at 1 (800) 424±9393 (or 366±0123 in Washington, D.C. area) or write to:
NHTSA, U.S. Department of Transportation. Washington, D.C. 20590. You
can also obtain other information about motor vehicle safety from the
Hotline.

REPAIRING PAINT CHIPS
Minor scratches or paint damage from road debris may be repaired with
Genuine Mazda Touch-Up Paint. Observe the application instructions on
the products.
Remove particles such as bird droppings, tree sap, insect remains, tar
spots, road salt and industrial fallout immediately.
CLEANING THE WHEELS
Wash with the same detergent as the body of your vehicle. Do not use
acid-based or alcohol-based wheel cleaners, steel wool, fuel or strong
detergents. Never use abrasives that will damage the finish of special
wheel surfaces. Use a tar remover to remove grease and tar.
The brushes used in some automatic car washes may damage the
finish on your wheels. Before going to a car wash, find out if the
brushes are abrasive.
CLEANING THE ENGINE
Engines are more efficient when they are clean because grease and dirt
buildup keep the engine warmer than normal. When washing:
²Take care when using a power washer to clean the engine. The high
pressure fluid could penetrate the sealed parts and cause damage.
²Do not spray with cold water to avoid cracking the engine block or
other engine components.
²Cover the highlighted areas to prevent water damage when cleaning
the engine.

²Never wash or rinse the engine while it is running; water in the
running engine may cause internal damage.
CLEANING NON-PAINTED PLASTIC EXTERIOR PARTS
Use vinyl cleaner for routine cleaning. Clean with a tar remover if
necessary. Do not clean plastic parts with thinners, solvents or
petroleum-based cleaners.
CLEANING MIRRORS
Do not clean your mirrors with a dry cloth or abrasive materials. Use a
soft cloth and mild detergent and water. Be careful when removing ice
from outside mirrors because you may damage the reflective surface.
CLEANING THE EXTERIOR LAMPS
Wash with the same detergent as the exterior of your vehicle. If
necessary, use a tar remover.
To avoid scratching the lamps, do not use a dry paper towel, chemical
solvents or abrasive cleaners.
CLEANING THE WIPER BLADES, WINDSHIELD AND REAR
WINDOW
If the wiper blades do not wipe properly, clean the wiper blade rubber
element with undiluted windshield washer solution or a mild detergent.
To avoid damaging the blades, do not use fuel, kerosene, paint thinner or
other solvents.

SCHEDULE II ± SPECIAL OPERATING CONDITIONS
If your driving habitsFREQUENTLYinclude one or more of the
following conditions:
²Short trips oflessthan 16 km (10 miles) when outside temperatures
remain below freezing.
²Towing a trailer, or carrying maximum loads.
²Operating in severe dust conditions.
²Operating duringhot weatherin stop-and-go ªrush-hourº traffic.
²Extensive idling, such as police, taxi or door-to-door delivery service.
²High speed operation with a fully loaded vehicle (max. GVW).
²Off-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.
