OVERHEATING
If the temperature gauge indicates overheating and you experience
power loss, you hear a loud knocking or pinging noise, the engine is
probably too hot.
If this happens:
1. Drive safely to the side of the road and park off the right-of-way.
2. Shift the automatic transmission into P (Park) or the manual
transmission into the neutral position, and apply the parking brake.
3. Turn off the air conditioner.
WARNING: Steam from an overheated engine is dangerous. The
escaping steam could seriously burn you. Open the hood ONLY
after steam is no longer escaping from the engine.
4. Check whether coolant or steam is escaping from under the hood or
from the engine compartment.

It is not recommended that the vehicle be operated in 4WD modes with
a ªtemporaryº (i.e. dissimilar size) spare. If 4WD operation is necessary,
do not operate above speeds of 16 km/h (10 mph) or for distances above
80 km (50 miles).
WARNING: If you use the temporary spare tire continuously or
do not follow these precautions, the tire could fail, causing you
to lose control of the vehicle, possibly injuring yourself or
others.
When driving with the temporary spare tiredo not:
²exceed 80 km/h (50 mph) or drive further than 3,200 km (2,000
miles) total under any circumstances
²load the vehicle beyond maximum vehicle load rating listed on the
Safety Compliance Label
²tow a trailer
²use more than one temporary spare tire at a time
Use of a temporary spare tire at any one wheel location can lead to
impairment of the following:
²Handling, stability and braking performance
²Comfort and noise
²Ground clearance and parking at curbs
²Winter driving capability
Conventional spare tire information (if equipped)
If you have the conventional spare tire, you can use it as a spare or a
regular tire. The spare is identical to the other tires on your vehicle,
although the wheel may not match.

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, 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.
SCHEDULED MAINTENANCE
Schedule I Ð 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.
²Repeated short-distance driving.
²Driving in dusty conditions.
²Towing a trailer.
²Operating in hot weather in stop-and-go ªrush hourº traffic.
²Extended periods of idling or low-speed operation.
²High-speed operation with a fully loaded vehicle.
²Off-road operation.
NOTE:After the described period, continue to follow the described
maintenance at the recommended intervals.

*4 Refer to vehicle emission control information label for spark plug and
gap specifications.
*5 The California Air Resources Board has determined that the failure to
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 Ð SPECIAL OPERATING CONDITIONS
If your driving habitsFREQUENTLYinclude one or more of the
following conditions:
²Short trips of less than 10 miles (16 km) 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 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.

²Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found in your vehicle service maintenance section.
Conditions
²Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
²Carrying unnecessary weight may reduce fuel economy (approximately
0.4 km/L [1 mpg] is lost for every 180 kg [400 lb] of weight carried).
²Adding certain accessories to your vehicle (for example bug
deflectors, rollbars/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
²Using fuel blended with alcohol may lower fuel economy.
²Fuel economy may decrease with lower temperatures during the first
12±16 km (8±10 miles) of driving.
²Driving on flat terrain offers improved fuel economy as compared to
driving on hilly terrain.
²Transmissions give their best fuel economy when operated in the top
cruise gear and with steady pressure on the gas pedal.
²Four-wheel-drive operation (if equipped) is less fuel efficient than
two-wheel-drive operation.
²Close 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:

TRANSMISSION FLUID
Checking automatic transmission fluid (if equipped)
Refer to your service maintenance section for scheduled intervals for
fluid checks and changes. Your transmission does not consume fluid.
However, the fluid level should be checked if the transmission is not
working properly, i.e., if the transmission slips or shifts slowly or if you
notice some sign of fluid leakage.
Automatic transmission fluid expands when warmed. To obtain an
accurate fluid check, drive the vehicle until it is at normal operating
temperature (approximately 30 km [20 miles]). If your vehicle has been
operated for an extended period at high speeds, in city traffic during hot
weather or pulling a trailer, the vehicle should be turned off for about 30
minutes to allow fluid to cool before checking.
²Refer to yourService Maintenance Sectionfor scheduled check and
change intervals.
²Transmission does not consume fluid.
²Check fluid when transmission is not operating properly or if you see
a leak.
²Fluid level must be checked at normal operating temperature, 30 km
(20 miles) of driving.
²DO NOT ADD fluid until the transmission is at normal operating
temperatures or the transmission will be overfilled.
To check and add fluid:
1. Drive the vehicle 30 km (20 miles) to reach normal operating
temperatures.
²If vehicle was driven in hot weather, city traffic, pulling a trailer, allow
transmission to cool for 30 minutes before checking.
2. Engage parking brake, start engine.
3. Put your foot on the brake pedal and move the gearshift lever slowly
through all of the gear ranges.
4. Shift to P (Park) and leave the engine running.
5. Remove the dipstick, wipe clean with a dry lint free rag.
6. Install and fully seat the dipstick into the filler tube.
