WARNING: When lifting a plastic-cased battery, excessive
pressure on the end walls could cause acid to flow through the
vent caps, resulting in personal injury and/or damage to the
vehicle or battery. Lift the battery with a battery carrier or with
your hands on opposite corners.
WARNING: Keep batteries out of reach of children. Batteries
contain sulfuric acid. Avoid contact with skin, eyes or clothing.
Shield your eyes when working near the battery to protect
against possible splashing of acid solution. In case of acid
contact with skin or eyes, flush immediately with water for a
minimum of 15 minutes and get prompt medical attention. If
acid is swallowed, call a physician immediately.
WARNING: Battery posts, terminals and related accessories
contain lead and lead compounds. Wash hands after handling.
Because your vehicle’s engine is electronically controlled by a computer,
some control conditions are maintained by power from the battery. When
the battery is disconnected or a new battery is installed, the engine must
relearn its idle and fuel trim strategy for optimum driveability and
performance. To begin this process: 1. With the vehicle at a complete stop, set the parking brake.
2. Put the gearshift lever in P (Park), turn off all accessories and start the engine.
3. Run the engine until it reaches normal operating temperature.
4. Allow the engine to idle for at least one minute.
5. Turn the A/C on and allow the engine to idle for at least one minute.
6. Drive the vehicle to complete the relearning process.
• The vehicle may need to be driven to relearn the idle and fuel trim
strategy.
• If you do not allow the engine to relearn its idle trim, the idle
quality of your vehicle may be adversely affected until the idle
trim is eventually relearned.

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 88 km/h [55 mph] uses 15%
less fuel than traveling at 105 km/h [65 mph]).
• 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 Lubricant specificationsin
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.

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.

INFORMATION ABOUT UNIFORM TIRE QUALITY GRADING
New vehicles are fitted with tires
that have a rating on them called
Tire Quality Grades. The Quality
grades can be found where
applicable on the tire sidewall
between tread shoulder and
maximum section width. For
example:
• Treadwear 200 Traction AA Temperature A
These Tire Quality Grades are determined by standards that the United
States Department of Transportation has set.

The tires on your vehicle have all weather treads to provide traction in
rain and snow. However, in some climates, you may need to use snow
tires and chains. If you need to use snow tires and chains, it is
recommended that steel wheels are used of the same size and
specifications as those originally installed.
Follow these guidelines when using snow tires and chains:
•Do not use tire chains on aluminum wheels. Chains may chip the
wheels.
• Use only SAE Class S chains.
• Install chains securely, verifying that the chains do not touch any
wiring, brake lines or fuel lines.
Drive cautiously. If you hear the cables or chains rub or bang
against the vehicle, stop and retighten them. If this does not
work, remove the cables or chains to prevent vehicle damage.
• If possible, avoid fully loading your vehicle.
• Remove the tire chains when they are no longer needed. Do not use
tire chains on dry roads.
• The suspension insulation and bumpers will help prevent vehicle
damage. Do not remove these components from your vehicle when
using snow tires and chains.
