Exterior Care
Followalllabel and container directions
when using a chemical cleaner or polish.
Read all warnings and cautions.
q Maintaining the Finish
Washing
CAUTION
Ø When the wiper lever is in the
AUTO position and the ignition is
switched ON, the wipers may
move automatically in the
following cases:
ØIf the windshield above the rain
sensor is touched or wiped with
a cloth.
ØIf the windshield is struck with
a hand or other object from
either outside or inside the
vehicle.
Keep hands and scrapers clear of
the windshield when the wiper
lever is in the AUTO position and
the ignition is switched ON as
fingers could be pinched or the
wipers and wiper blades damaged
when the wipers activate
automatically.
If you are going to clean the
windshield, be sure the wipers are
turned off completely ―this is
particularly important when
clearing ice and snow ―when it is
most likely that the engine is left
running.
Ø Do not spray water in the engine
compartment. Otherwise, it could
result in engine-starting problems
or damage to electrical parts. To help protect the finish from rust and
deterioration, wash your Mazda
thoroughly and frequently, at least once a
month, with lukewarm or cold water.
If the vehicle is washed improperly, the
paint surface could be scratched. Here are
some examples of how scratching could
occur.
Scratches occur on the paint surface
when:
lThe vehicle is washed without first
rinsing off dirt and other foreign
matter.
lThe vehicle is washed with a rough,
dry, or dirty cloth.
lThe vehicle is washed at a car wash
that uses brushes that are dirty or too
stiff.
lCleansers or wax containing abrasives
are used.
NOTE
lMazda is not responsible for scratches
caused by automatic car washes or
improper washing.
lScratches are more noticeable on vehicles
with darker paint finishes.
To minimize scratches on the vehicle's
paint finish:
lRinse off any dirt or other foreign
matter using lukewarm or cold water
before washing.
lUse plenty of lukewarm or cold water
and a soft cloth when washing the
vehicle. Do not use a nylon cloth.
lRub gently when washing or drying the
vehicle.
lTake your vehicle only to a car wash
that keeps its brushes well maintained.
lDo not use abrasive cleansers or wax
that contain abrasives.

WARNING
Dry wet brakes by driving very slowly
and applying the brakes lightly until
brake performance is normal:Driving with wet brakes is
dangerous. Increased stopping
distance or the vehicle pulling to one
side when braking could result in a
serious accident. Light braking will
indicate whether the brakes have
been affected.
qAluminum Wheel Maintenanceí
A protective coating is provided over the
aluminum wheels. Special care is needed
to protect this coating.
CAUTION
Do not use any detergent other than
mild detergent. Before using any
detergent, verify the ingredients.
Otherwise, the product could discolor
or stain the aluminum wheels. NOTE
lDo not use a wire brush or any abrasive
cleaner, polishing compound, or solvent on
aluminum wheels. They may damage the
coating.
lAlways use a sponge or soft cloth to clean
the wheels.
Rinse the wheels thoroughly with lukewarm
or cold water. Also, be sure to clean the
wheels after driving on dusty or salted
roads to help prevent corrosion.
lAvoid washing your vehicle in an automatic
car wash that uses high-speed or hard
brushes.
lIf your aluminum wheels lose luster, wax
the wheels.
(With Tire Pressure Monitoring System)
Check special requirements for Tire Pressure
Monitoring System.
Refer to Tires and Wheels on page 5-35.
q Plastic Part Maintenance
lWhen cleaning the plastic lenses of the
lights, do not use gasoline, kerosene,
rectified spirit, paint, thinner, highly
acidic detergents, or strongly alkaline
detergents. Otherwise, these chemical
agents can discolor or damage the
surfaces resulting in a significant loss
in functionality. If plastic parts become
inadvertently exposed to any of these
chemical agents, flush with water
immediately.
lIf plastic parts such as the bumpers
become inadvertently exposed to
chemical agents or fluids such as
gasoline, oil, engine coolant, or battery
fluid, it could cause discoloration,
staining, or paint peeling. Wipe off any
such chemical agents or fluids using a
soft cloth immediately.

Outside the United States
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 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 the United States. However, in the event that you are moving to Canada
permanently, Mazda vehicles built for use in the United States could be eligible for
exportation to Canada with specific vehicle modifications to comply with the Canadian
Motor Vehicle Safety Standards (CMVSS).
NOTE
The above is applicable for a permanent import/export situation and not related to travelers on
vacation.
You may have the following problems if you do take your vehicle outside of the United
States:
lRecommended fuel may be unavailable. Any kind of leaded fuel or low-octane fuel will
affect vehicle performance and damage the emission controls and engine.
lProper repair facilities, tools, testing equipment, and replacement parts may not be
available.
Please refer to your Manufacturer's Warranty Booklet for more information.

Add-On Non-Genuine Parts and Accessories
Non-genuine parts and accessories for Mazda vehicles can be found in stores.
These may fit your vehicle, but they are not approved by Mazda for use with Mazda
vehicles. When you install non-genuine parts or accessories, they could affect your
vehicle's performance or safety systems; the Mazda warranty doesn't cover this. Before you
install any non-genuine parts or accessories, consult an Authorized Mazda Dealer.
WARNING
Always consult an Authorized Mazda Dealer before you install non-genuine parts or
accessories:Installation of non-genuine parts or accessories is dangerous. Improperly designed
parts or accessories could seriously affect your vehicle's performance or safety
systems. This could cause you to have an accident or increase your chances of
injuries in an accident.
Be very careful in choosing and installing add-on electrical equipment, such as
mobile telephones, two-way radios, stereo systems, and car alarm systems: Incorrectly choosing or installing improper add-on equipment or choosing an
improper installer is dangerous. Essential systems could be damaged, causing engine
stalling, air-bag (SRS) activation, ABS/TCS/DSC inactivation, or a fire in the vehicle.
Mazda assumes no responsibility for death, injury, or expenses that may result from the
installation of add-on non-genuine parts or accessories.
