• 3.0L & 4.0L engines
When the engine is cold, check the level of the engine coolant in the
reservoir.
• The engine coolant should be at the “cold fill level” or within the “cold
fill range” as listed on the engine coolant reservoir (depending upon
application).
• Confirm the color and type of engine coolant before adding, to avoid
mixing incompatible products.
• Refer to the service maintenance section for service interval
schedules.
• Be sure to read and understand Precautions when servicing your
vehicle in this chapter.

If you are experiencing a rough or rolling idle after start-up with the
outside temperature above 27° C (80° F), the idle should improve within
10 to 30 seconds. If the problems persist below this temperature, see
your authorized Mazda dealership.
Cleaner air
Mazda endorses the use of reformulated “cleaner-burning” gasolines to
improve air quality.
Running out of fuel
Avoid running out of fuel because this situation may have an adverse
affect on powertrain components.
If you have run out of fuel:
•You may need to cycle the ignition from OFF to ON several times after
refueling, to allow the fuel system to pump the fuel from the tank to
the engine.
• Your “Check Engine” indicator may come on. For more information on
the “Check Engine” indicator, refer to the Instrument Cluster
chapter.
Fuel Filter
For fuel filter replacement, see your authorized Mazda dealership. Refer
to the service maintenance section for the appropriate intervals for
changing the fuel filter.
Replace the fuel filter with an authorized Mazda part. The
customer warranty may be void for any damage to the fuel system
if an authorized Mazda fuel filter is not used.
ESSENTIALS OF GOOD FUEL ECONOMY
Measuring techniques
Your best source of information about actual fuel economy is you, the
driver. You must gather information as accurately and consistently as
possible. Fuel expense, frequency of fillups or fuel gauge readings are
NOT accurate as a measure of fuel economy. We do not recommend
taking fuel economy measurements during the first 1,600 km (1,000
miles) of driving (engine break-in period). You will get a more accurate
measurement after 3,000 km–5,000 km (2,000 miles-3,000 miles).
Filling the tank
The advertised fuel capacity of the fuel tank on your vehicle is equal to
the rated refill capacity of the fuel tank as listed in the Refill capacities
section of this chapter.

Check the power steering fluid. Refer to the service maintenance section
for the service interval schedules. If adding fluid is necessary, use only
MERCONAT F.
1. Start the engine and let it run until it reaches normal operating temperature (the engine coolant temperature gauge indicator will be
near the center of the normal area between H and C).
2. While the engine idles, turn the steering wheel left and right several times.
3. Turn the engine off.
4. If your vehicle is equipped with a 3.0L V6 engine, check the
fluid level on the dipstick. It should be within the FULL HOT range.
Do not add fluid if the level is within this range.
5. If your vehicle is equipped with a 4.0L SOHC V6 or 2.3L I4
engine, check the fluid level in the reservoir. It should be between
the MIN and MAX lines. Do not add fluid if the level is within this
range.
6. If the fluid is low, add fluid in small amounts, continuously checking the level until it reaches the FULL HOT range. Be sure to put the
dipstick back in the reservoir.
BRAKE FLUID RESERVOIR
The fluid level will drop slowly as
the brakes wear, and will rise when
the brake components are replaced.
Fluid levels below the “MAX” line
that do not trigger the brake system
warning lamp are within the normal
operating range, there is no need to
add fluid. If the fluid levels are outside of the normal operating range,
the performance of your brake system could be compromised, seek
service from your Mazda dealer immediately. WARNING: Brake fluid is toxic. If brake fluid contacts the
eyes, flush eyes with running water for 15 minutes. Seek
medical attention if irritation persists. If taken internally, drink
water and induce vomiting. Seek medical attention immediately.

WARNING: If you use a brake fluid that is not DOT 3, you will
cause permanent damage to your brakes.
WARNING: Do not let the reservoir for the master cylinder run
dry. This may cause the brakes to fail.
CLUTCH FLUID (IF EQUIPPED)
Check the fluid level. Refer to the service maintenance section for the
service interval schedules.
During normal operation, the fluid level in the clutch reservoir should
remain constant. If the fluid level drops, refill the fluid level to the step
in the reservoir.
Use only a DOT 3 brake fluid designed to meet Mazda specification.
Refer to Lubricant Specifications in this chapter.
WARNING: Brake fluid is toxic. If brake fluid contacts the
eyes, flush eyes with running water for 15 minutes. Seek
medical attention if irritation persists. If taken internally, drink
water and induce vomiting. Seek medical attention immediately.
1. Clean the reservoir cap before removal to prevent dirt and
water from entering the
reservoir.
2. Remove cap and rubber diaphragm from reservoir.
3. Add fluid until the level reaches the step in the reservoir.
4. Reinstall rubber diaphragm and cap onto reservoir.

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.
•Refer to your Service Maintenance Section for scheduled check and
change intervals.
• Transmission does not consume fluid.
• Check fluid when transmission is not operating properly or if you see
a leak.
• Fluid level must be checked at normal operating temperature, 30 km
(20 miles) of driving.
• DO 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.
• If 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.

4. Replace the valve cap.
5. Repeat this procedure for each tire, including the spare.
Note: Some spare tires require higher inflation pressure than the other
tires.
6. Visually inspect the tires to make sure there are no nails or other objects embedded that could poke a hole in the tire and cause an air
leak.
7. Check the sidewalls to make sure there are no gouges, cuts, bulges or other irregularities.
Tire and wheel alignment
A bad jolt from hitting a curb or pothole can cause the front end of your
vehicle to become misaligned or damage to your tires. If your vehicle
seems to pull to one side, vibrate or shake when you’re driving, the
wheels may be out of alignment. Have a qualified technician at a
reputable repair facility check the wheel alignment periodically.
Wheel misalignment in the front or the rear can cause uneven and rapid
treadwear of your tires and should be corrected by a qualified technician
at a reputable repair facility. Front wheel drive (FWD) vehicles, and
those with independent front suspension require alignment of all four
wheels.
The tire should also be balanced periodically. An unbalanced tire and
wheel assembly may result in irregular tire wear.
NOTE: When it is time to replace front tires with new ones, this is an
ideal time to perform an alignment. New tires should be balanced at the
time they are installed.
Tire rotation
Rotating your tires at the recommended interval (as indicated in the
Service Maintenance Guide that comes with your vehicle) will help your
tires wear more evenly providing better tire performance and longer tire
life. Unless otherwise specified, rotate the tires approximately every
8,000 km (5,000 miles).
