SCHEDULE II — SPECIAL OPERATING CONDITIONS

If your driving habits FREQUENTLY include 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 during hot weather in 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.

The owner or a qualified service technician should make these vehicle
inspections at the indicated intervals to ensure safe and dependable

Bring any problem to the attention of an Authorized Mazda Dealer or
qualified service technician as soon as possible.

While operating your vehicle
• Note any changes in the sound of the exhaust or any smell or exhaust

fumes in the vehicle.

• Check for vibrations in the steering wheel. Notice any increased

steering effort or looseness in the steering wheel, or change in the
straight ahead position.

• Notice if your vehicle constantly turns slightly or “pulls” to one side

when traveling on a smooth, level road.

• When stopping, listen and check for strange sounds, pulling to one

side, increased brake pedal travel or “hard to push” brake pedal.

• If any slipping or changes in the operation of your transmission occur,

check the transmission fluid level.

• Check automatic transmission Park function.
• Check parking brake.
At least monthly
• Check function of all interior and exterior lights.
• Check tires for wear and proper air pressure.
• Check engine oil level.
• Check coolant level in the coolant reservoir.
• Check washer fluid level.
At least twice a year (for example, every spring and fall)
• Check power steering fluid level.
• Check clutch fluid level (if equipped).
• Check and clean body and door drain holes.
• Check and lubricate all hinges, latches, and outside locks.

operation.

• Check cooling system fluid level and verify coolant specific gravity is

correct for summer or winter conditions.

• Check battery water level (non-maintenance free).
• Check battery connections and clean if necessary.

SERVICE RECOMMENDATIONS

To help you service your vehicle:
• We highlight do-it-yourself items in the engine compartment for easy

location.

• We provide a Scheduled Maintenance section which makes tracking

routine service easy.

If your vehicle requires professional service, your dealership can provide
necessary parts and service. Check your “Warranty Information” to find
out which parts and services are covered.

Use only recommended fuels, lubricants, fluids and service parts
conforming to specifications. Genuine Mazda parts are designed and built
to provide the best performance in your vehicle.

PRECAUTIONS WHEN SERVICING YOUR VEHICLE

• Do not work on a hot engine.
• Make sure that nothing gets caught in moving parts.
• Do not work on a vehicle with the engine running in an enclosed

space, unless you are sure you have enough ventilation.

• Keep all open flames and other lit material away from the battery and

all fuel related parts.

WINDSHIELD WASHER FLUID

Windshield washer fluid

Add fluid to fill the reservoir if the
level is low. In very cold weather, do
not fill the reservoir completely.

Only use a washer fluid that meets Mazda specification . Refer to
Lubricant specifications in this chapter.

State or local regulations on volatile organic compounds may restrict the
use of methanol, a common windshield washer antifreeze additive.
Washer fluids containing non-methanol antifreeze agents should be used
only if they provide cold weather protection without damaging the
vehicle’s paint finish, wiper blades or washer system.

WARNING: If you operate your vehicle in temperatures below
4.5° C (40° F), use washer fluid with antifreeze protection.
Failure to use washer fluid with antifreeze protection in cold
weather could result in impaired windshield vision and increase
the risk of injury or accident.

Note: Do not put washer fluid in the engine coolant reservoir. Washer
fluid placed in the cooling system may harm engine and cooling system
components.

Checking the engine oil

Refer to the service maintenance section for the appropriate intervals for
checking the engine oil.

1. Make sure the vehicle is on level ground.

2. Turn the engine off and wait a few minutes for the oil to drain into

the oil pan.

3. Set the parking brake and ensure the gearshift is securely latched in

P (Park) (automatic transmission) or 1 (First) (manual
transmission).

4. Open the hood. Protect yourself from engine heat.

• 4.0L SOHC V6 engine

SAE 5W-30

• Oil levels above the MAX mark may cause engine damage. Some oil

must be removed from the engine by a service technician.

7. Put the indicator back in and ensure it is fully seated.

Adding engine oil

1. Check the engine oil. For instructions, refer to Checking the engine

oil in this chapter.

2. If the engine oil level is not within the normal range, add only

certified engine oil of the recommended viscosity. Remove the engine
oil filler cap and use a funnel to pour the engine oil into the opening.

3. Recheck the engine oil level. Make sure the oil level is not above the

MAX mark or the letter F in FULL on the engine oil level indicator
(dipstick).

4. Install the indicator and ensure it is fully seated.

5. Fully install the engine oil filler cap by turning the filler cap 1/4 turn

until it stops.

To avoid possible oil loss, DO NOT operate the vehicle with the
engine oil level indicator and/or the engine oil filler cap removed.

4.0L Engine

Look for this certification
trademark.

SAE 5W-30 engine oil is recommended.

Only use oils “Certified For Gasoline Engines” by the American
Petroleum Institute (API). Use an equivalent Mazda Specification.

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.
