Driving while you tow
When towing a trailer:
•Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
•Consult your local motor vehicle speed regulations for towing a trailer.
•To eliminate excessive shifting, use a lower gear. This will also assist
in transmission cooling. (For additional information, refer to the
Driving with a 5–speed automatic transmissionsection in the
Drivingchapter.)
•Under extreme conditions with large frontal trailers, high outside
temperatures and highway speeds, the coolant gauge may indicate
higher than normal coolant temperatures. If this occurs, reduce speed
until the coolant temperature returns to the normal range. Refer to
Engine coolant temperature gaugein theInstrument Cluster
chapter.
•Anticipate stops and brake gradually.
•Do not exceed the GCWR rating or transmission damage may occur.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to yourService Maintenance Section
for more information.

INTRODUCTION
Be extremely careful to prevent injury to yourself and others or 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.
Claims against the warranty resulting from lack of maintenance, as
opposed to defective materials or authorized Mazda workmanship, will
not be honored.
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.

perform this maintenance item will not nullify the emission warranty nor

SCHEDULE 2—SPECIAL OPERATING CONDITIONS
If your driving habitsFREQUENTLYinclude one or more of the
following conditions:
•Short trips of less than 10 miles (16 km) when outside temperatures
remain below freezing.
•Towing a trailer, or carrying maximum loads.
•Operating in severe dust conditions.
•Operating duringhot 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 3,000 miles
(4,800 km) 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 or 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.

Do not use supplemental engine oil additives, oil treatments or engine
treatments. They are unnecessary and could, under certain conditions,
lead to engine damage which is not covered by your warranty.
Change your engine oil according to the appropriate schedule listed in
the service maintenance section.
Engine Oil Filter Recommendation
Change your engine oil filter according to the appropriate schedule listed
in the service maintenance section. Mazda production and aftermarket
(Mazda) oil filters are designed for added engine protection and long life.
If a replacement oil filter is used that does not meet Mazda Material and
design specifications, start-up engine noises or knock may be
experienced.
It is recommended you use the appropriate Mazda oil filter (or another
brand meeting Mazda specifications) for your engine.
BATTERY
Your vehicle is equipped with a
Mazda maintenance-free battery
which normally does not require
additional water during its life of
service.
However, for severe usage or in high temperature climates, check the
battery electrolyte level. Refer to theService Maintenance Sectionfor
the service interval schedules.
Keep the electrolyte level in each cell up to the“level indicator”.
Do not overfill the battery cells.
If possible, try to only fill the battery cells with distilled water. If the
battery needs water often, have the charging system checked.
If your battery has a cover/shield, make sure it is reinstalled
after the battery has been cleaned or replaced.

schedules.
•Be sure to read and understandPrecautions when servicing your
vehiclein this chapter.
If the engine coolant has not been checked at the recommended interval,
the engine coolant reservoir may become low or empty. If the reservoir is
low or empty, add engine coolant to the reservoir. Refer toAdding
