Keep a record for at least one month and record the type of driving (city
or highway). This will provide an accurate estimate of the vehicle’s fuel
economy under current driving conditions. Additionally, keeping records
during summer and winter will show how temperature impacts fuel
economy. In general, lower temperatures give lower fuel economy.
Driving style — good driving and fuel economy habits
Give consideration to the lists that follow and you may be able to change
a number of variables and improve your fuel economy.
Habits
•Smooth, moderate operation can yield up to 10% savings in fuel.
•
Steady speeds without stopping will usually give the best fuel economy.
•Idling for long periods of time (greater than one minute) may waste fuel.
• Anticipate stopping; slowing down may eliminate the need to stop.
• Sudden or hard accelerations may reduce fuel economy.
• Slow down gradually.
• Driving at reasonable speeds (traveling at 55 mph [88 km/h] uses 15%
less fuel than traveling at 65 mph [105 km/h]).
• Revving the engine before turning it off may reduce fuel economy.
• Using the air conditioner or defroster may reduce fuel economy.
•
You may want to turn off the speed control in hilly terrain if unnecessary
shifting between fourth and fifth gear occurs. Unnecessary shifting of
this type could result in reduced fuel economy.
• Warming up a vehicle on cold mornings is not required and may
reduce fuel economy.
• Resting your foot on the brake pedal while driving may reduce fuel
economy.
• Combine errands and minimize stop-and-go driving.
Maintenance
• Keep tires properly inflated and use only recommended size.
• Operating a vehicle with the wheels out of alignment will reduce fuel
economy.
• Use recommended engine oil. Refer to the Maintenance product
specifications and capacities section of this chapter.
• Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found in scheduled maintenance.

•Do not turn off the ignition while your vehicle is moving, especially at
high speeds.
• Have the items listed in the scheduled maintenancesection
performed according to the specified schedule.
The scheduled maintenance items listed in the scheduled maintenance
section are essential to the life and performance of your vehicle and to
its emissions system.
If other than Mazda authorized parts are used for maintenance
replacements or for service of components affecting emission control,
such non-Mazda parts should be equivalent to genuine Mazda parts in
performance and durability.
WARNING: Do not park, idle, or drive your vehicle in dry grass
or other dry ground cover. The emission system heats up the
engine compartment and exhaust system, which can start a fire.
Illumination of the
indicator, charging system warning light or the
temperature warning light, fluid leaks, strange odors, smoke or loss of
engine power, could indicate that the emission control system is not
working properly.
WARNING: Exhaust leaks may result in entry of harmful and
potentially lethal fumes into the passenger compartment.
Do not make any unauthorized changes to your vehicle or engine. By
law, vehicle owners and anyone who manufactures, repairs, services,
sells, leases, trades vehicles, or supervises a fleet of vehicles are not
permitted to intentionally remove an emission control device or prevent
it from working. Information about your vehicle’s emission system is on
the Vehicle Emission Control Information Decal located on or near the
engine. This decal identifies engine displacement and gives some tune up
specifications.
Please consult your “Warranty Information” for complete emission
warranty information.
On board diagnostics (OBD-II)
Your vehicle is equipped with a computer that monitors the engine’s
emission control system. This system is commonly known as the On
Board Diagnostics System (OBD-II). This OBD-II system protects the
environment by ensuring that your vehicle continues to meet
2007 B-Series (mbs)
Owners Guide (post-2002-fmt)
USA (fus)
Maintenance and Specifications
251

government emission standards. The OBD-II system also assists your
authorized dealer in properly servicing your vehicle. When the
indicator illuminates, the OBD-II system has detected a malfunction.
Temporary malfunctions may cause the
indicator to illuminate.
Examples are:
1. The vehicle has run out of fuel—the engine may misfire or run poorly.
2. Poor fuel quality or water in the fuel.
3. The fuel cap may not have been securely tightened. See Fuel filler
cap in this chapter.
These temporary malfunctions can be corrected by filling the fuel tank
with good quality fuel and/or properly tightening the fuel cap. After three
driving cycles without these or any other temporary malfunctions
present, the
indicator should turn off—A driving cycle consists of a
cold engine startup followed by mixed city/highway driving. No additional
vehicle service is required.
If the
indicator remains on, have your vehicle serviced at the first
available opportunity.
Readiness for Inspection/Maintenance (I/M) testing
In some localities, it may be a legal requirement to pass an I/M test of
the on-board diagnostics system. If the
indicator is on, refer to the
description in the Warning lights and chimes section of the
Instrument Cluster chapter. Your vehicle may not pass the I/M test with
the
indicator on.
If the vehicle’s powertrain system or its battery has just been serviced,
the on-board diagnostics system is reset to a “not ready for I/M test”
condition. To ready the on-board diagnostics system for I/M testing, a
minimum of 30 minutes of city and highway driving is necessary as
described below:
• First, at least 10 minutes of driving on an expressway or highway.
• Next, at least 20 minutes driving in stop-and-go, city-type traffic with
at least four idle periods.
Allow the vehicle to sit for at least eight hours without starting the
engine. Then, start the engine and complete the above driving cycle. The
engine must warm up to its normal operating temperature. Once started,
do not turn off the engine until the above driving cycle is complete.

1. Start the engine and let it run until it reaches normal operatingtemperature (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. 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.
5. 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
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 authorized 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.

2. If driven in hot weather, city traffic, pulling a trailer, allowtransmission to cool for 30 minutes before checking.
3. Engage parking brake, start engine.
4. Put your foot on the brake pedal and move the gearshift lever slowly through all of the gear ranges.
5. Shift to P (Park) and leave the engine running.
6. Remove the dipstick, wipe clean with a dry lint free rag.
7. Install and fully seat the dipstick into the filler tube.
8. Remove the dipstick and inspect the fluid level. Level should be
in the cross-hatched area.
9. If necessary, add fluid in 1/2 pint (250ml) increments through the filler tube until the level is correct at normal operating temperatures.
Refer to the Maintenance product specifications and capacities
section in this chapter for the correct fluid type. The use of any
other non-approved fluid may cause internal transmission damage.
10. Fluid can be checked at ambient temperatures between 50–95°F
(10–30°C). DO NOT ADD fluid
until the transmission is at
normal operating temperatures or the transmission will be overfilled.
Low fluid level
Do not drive the vehicle if the fluid
level is at or below the bottom of
the dipstick.
High fluid level
Fluid levels above the safe range
may cause overheating, shift and/or
engagement concerns and internal
transmission damage. If an overfill
condition occurs, excess fluid should
be removed by an authorized dealer.

the performance of your brake system could be compromised, seek service from your authorized
dealer immediately.2Add the coolant type originally equipped in your vehicle. Do not mix different colors or types of
coolant. Do not use Mazda Extended Life Engine Coolant (orange in color). Refer to Adding
engine coolant, in this chapter.3Service refill capacity is determined by filling the transmission to the bottom of the filler hole with
the vehicle on a level surface.4Ensure the correct automatic transmission fluid is used. Transmission fluid requirements are
indicated on the dipstick or on the dipstick handle. MERCON
and MERCON
V are not
interchangeable. DO NOT mix MERCON
and MERCON
V. Refer toscheduled maintenance to
determine the correct service interval.5Indicates only approximate dry-fill capacity. Some applications may vary based on cooler size and
if equipped with an in-tank cooler. The amount of transmission fluid and fluid level should be set
by the indication on the dipstick’s normal operating range.6Traction-Lok axles use 4.75–5.0 pints (2.2–2.4L) of rear axle lubricant. Add 4 oz. (118 ml) of
Additive Friction Modifier meeting Mazda specifications for complete refill of Traction-Lok axles.
Service refill capacities are determined by filling the rear axle 1/4 inch to 9/16 inch (6 mm to 14
mm) below the bottom of the filler hole.
If submerged in water, the rear axle lubricant should be changed.
