MAZDA MODEL B4000 CAB PLUS 4 TRUCK 2008 Owners Manual

If the engine coolant has not been checked at the recommended interval,
the engine coolant reservoir may become low or empty. If the reservoir is
low or empty, add engine coolant to the reservoir. Refer toAdding
engine coolant in this chapter.
Note: Automotive fluids are not interchangeable; do not use engine
coolant, antifreeze or windshield washer fluid outside of its specified
function and vehicle location.
Adding engine coolant
Use only Mazda Genuine Engine Coolant or a premium engine
coolant that meets a Mazda specification.
• DO NOT USE Extended Life Engine Coolant (orange in color).
• DO NOT USE a DEX-COOL engine coolant or an equivalent
engine coolant.
• DO NOT USE alcohol or methanol antifreeze or any engine
coolants mixed with alcohol or methanol antifreeze.
• DO NOT USE supplemental coolant additives in your vehicle.
These additives may harm your engine’s cooling system.
• DO NOT MIX different colors or types of coolant in your
vehicle. Make sure the correct coolant is used.
• DO NOT MIX recycled coolant and conventional coolant
together in your vehicle. Mixing of engine coolants may harm
your engine’s cooling system.
• The use of an improper coolant may harm engine and cooling
system components and may void the warranty of your vehicle’s
engine cooling system. If you are unsure which type of coolant
your vehicle requires, contact your local authorized dealer.
WARNING: Do not put engine coolant in the windshield washer
fluid reservoir. If engine coolant is sprayed onto the windshield,
it could make it difficult to see through the windshield.
When adding coolant, make sure it is a 50/50 mixture of engine coolant
and distilled water. Add the mixture to the coolant reservoir, when the
engine is cool, until the appropriate fill level is obtained.
• NEVER increase the coolant concentration above 60%.
• NEVER decrease the coolant concentration below 40%.
• Engine coolant concentrations above 60% or below 40% will
decrease the freeze protection characteristics of the engine
coolant and may cause engine damage.

A large amount of water without engine coolant may be added, in case of
emergency, to reach a vehicle service location. In this instance, the
cooling system must be drained and refilled with a 50/50 mixture of
engine coolant and distilled water as soon as possible. Water alone
(without engine coolant) can cause engine damage from corrosion,
overheating or freezing.
For vehicles with overflow coolant systems with a non-pressurized cap
on the coolant recovery system, add coolant to the coolant recovery
reservoir when the engine is cool. Add the proper mixture of coolant and
water to the “COLD FILL RANGE”. For all other vehicles, which have a
coolant degas system with a pressurized cap, or if it is necessary to
remove the coolant pressure relief cap on the radiator of a vehicle with
an overflow system, follow these steps to add engine coolant.1. Before you begin, turn the engine off and let it cool.
2. When the engine is cool, wrap a thick cloth around the coolant pressure relief cap on the coolant reservoir (an opaque plastic
bottle). Slowly turn cap counterclockwise (left) until pressure begins
to release.
3. Step back while the pressure releases.
4. When you are sure that all the pressure has been released, use the cloth to turn it counterclockwise and remove the cap.
5. Fill the coolant reservoir slowly with the proper coolant mixture (see above), to within the “COLD FILL RANGE” or the “FULL COLD”
level on the reservoir. If you removed the radiator cap in an overflow
system, fill the radiator until the coolant is visible and radiator is
almost full.
6. Replace the cap. Turn until tightly installed. Cap must be tightly installed to prevent coolant loss.
After any coolant has been added, check the coolant concentration.
Refer to the Checking engine coolant section. If the concentration is
not 50/50 (protection to –34° F [–36° C]), drain some coolant and adjust
the concentration. It may take several drains and additions to obtain a
50/50 coolant concentration.
Whenever coolant has been added, the coolant level in the coolant
reservoir should be checked the next few times you drive the vehicle. If
necessary, add enough 50/50 concentration of engine coolant and
distilled water to bring the liquid level to the proper level.
If you have to add more than 1.0 quart (1.0 liter) of engine coolant per
month, have your authorized dealer check the engine cooling system.

Your cooling system may have a leak. Operating an engine with a low
level of coolant can result in engine overheating and possible engine
damage).
Recycled engine coolant
Mazda Motor Corporation does NOT recommend the use of recycled
engine coolant in vehicles originally equipped with Mazda Premium Gold
Engine Coolant since a Mazda-approved recycling process is not yet
available.
Used engine coolant should be disposed of in an appropriate
manner. Follow your community’s regulations and standards for recycling
and disposing of automotive fluids.
Coolant refill capacity
To find out how much fluid your vehicle’s cooling system can hold, refer
to Maintenance product specifications and capacities in this chapter.
Fill your engine coolant reservoir as outlined in Adding engine coolant
in this section.
Severe climates
If you drive in extremely cold climates (less than –34°F [–36°C ]):
• It may be necessary to increase the coolant concentration
above 50%.
• NEVER increase the coolant concentration above 60%.
• Increased engine coolant concentrations above 60% will
decrease the overheat protection characteristics of the engine
coolant and may cause engine damage.
• Refer to the chart on the coolant container to ensure the
coolant concentration in your vehicle will provide adequate
freeze protection at the temperatures in which you drive in the
winter months.
If you drive in extremely hot climates:
• It is still necessary to maintain the coolant concentration
above 40%.
• NEVER decrease the coolant concentration below 40%.
• Decreased engine coolant concentrations below 40% will
decrease the corrosion protection characteristics of the engine
coolant and may cause engine damage.

•Decreased engine coolant concentrations below 40% will
decrease the freeze protection characteristics of the engine
coolant and may cause engine damage.
• Refer to the chart on the coolant container to ensure the
coolant concentration in your vehicle will provide adequate
protection at the temperatures in which you drive.
Vehicles driven year-round in non-extreme climates should use a 50/50
mixture of engine coolant and distilled water for optimum cooling system
and engine protection.
FUEL FILTER
For fuel filter replacement, see your authorized dealer. Refer to
scheduled maintenance information 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.
WHAT YOU SHOULD KNOW ABOUT AUTOMOTIVE FUELS
Important safety precautions
WARNING: Do not overfill the fuel tank. The pressure in an
overfilled tank may cause leakage and lead to fuel spray and
fire.
WARNING: The fuel system may be under pressure. If the fuel
filler cap is venting vapor or if you hear a hissing sound, wait
until it stops before completely removing the fuel filler cap.
Otherwise, fuel may spray out and injure you or others.
WARNING: If you do not use the proper fuel filler cap,
excessive vacuum in the fuel tank may damage the fuel system
or cause the fuel cap to disengage in a collision, which may
result in possible personal injury.
WARNING: Automotive fuels can cause serious injury or death
if misused or mishandled.

WARNING: Gasoline may contain benzene, which is a
cancer-causing agent.
Observe the following guidelines when handling automotive fuel:
• Extinguish all smoking materials
and any open flames before
refueling your vehicle.
• Always turn off the vehicle before
refueling.
• Automotive fuels can be harmful
or fatal if swallowed. Fuel such as gasoline is highly toxic and if
swallowed can cause death or permanent injury. If fuel is swallowed,
call a physician immediately, even if no symptoms are immediately
apparent. The toxic effects of fuel may not be visible for hours.
• Avoid inhaling fuel vapors. Inhaling too much fuel vapor of any kind
can lead to eye and respiratory tract irritation. In severe cases,
excessive or prolonged breathing of fuel vapor can cause serious
illness and permanent injury.
• Avoid getting fuel liquid in your eyes. If fuel is splashed in the eyes,
remove contact lenses (if worn), flush with water for 15 minutes and
seek medical attention. Failure to seek proper medical attention could
lead to permanent injury.
• Fuels can also be harmful if absorbed through the skin. If fuel is
splashed on the skin and/or clothing, promptly remove contaminated
clothing and wash skin thoroughly with soap and water. Repeated or
prolonged skin contact with fuel liquid or vapor causes skin irritation.
• Be particularly careful if you are taking “Antabuse” or other forms of
disulfiram for the treatment of alcoholism. Breathing gasoline vapors,
or skin contact could cause an adverse reaction. In sensitive
individuals, serious personal injury or sickness may result. If fuel is
splashed on the skin, promptly wash skin thoroughly with soap and
water. Consult a physician immediately if you experience an adverse
reaction.
WARNING: When refueling always shut the engine off and
never allow sparks or open flames near the filler neck. Never
smoke while refueling. Fuel vapor is extremely hazardous under
certain conditions. Care should be taken to avoid inhaling
excess fumes.

WARNING: The flow of fuel through a fuel pump nozzle can
produce static electricity, which can cause a fire if fuel is
pumped into an ungrounded fuel container.
Refueling WARNING: Fuel vapor burns violently and a fuel fire can cause
severe injuries. To help avoid injuries to you and others:
• Read and follow all the instructions on the pump island;
• Turn off your engine when you are refueling;
• Do not smoke if you are near fuel or refueling your vehicle;
• Keep sparks, flames and smoking materials away from fuel;
• Stay outside your vehicle and do not leave the fuel pump
unattended when refueling your vehicle — this is against the
law in some places;
• Keep children away from the fuel pump; never let children
pump fuel.
Use the following guidelines to avoid electrostatic charge build-up when
filling an ungrounded fuel container:
• Place approved fuel container on the ground.
• DO NOT fill a fuel container while it is in the vehicle (including the
cargo area).
• Keep the fuel pump nozzle in contact with the fuel container while
filling.
• DO NOT use a device that would hold the fuel pump handle in the fill
position.
Fuel Filler Cap
Your fuel tank filler cap has an indexed design with a 1/4 turn on/off
feature.
When fueling your vehicle: 1. Turn the engine/ignition switch to the off position.
2. Carefully turn the filler cap counterclockwise until it spins off.
3. To install the cap, align the lugs on the cap with the threads on the filler pipe.
4. Turn the filler cap clockwise until it clicks at least once.

If the check fuel cap lampor a “check fuel cap” message come on,
the fuel filler cap may not be properly installed. The lamp or message
can come on after several driving events after you’ve refueled your
vehicle.
At the next opportunity, safely pull off of the road, remove the fuel filler
cap, align the cap properly and reinstall it. The check fuel cap
lamp
or “check fuel cap” message may not reset immediately; it may
take several driving cycles for the check fuel cap lamp
or “check fuel
cap” message to turn off. A driving cycle consists of an engine start-up
(after four or more hours with the engine off) followed by city and
highway driving.
Continuing to drive with the check fuel cap lamp
or “check fuel cap”
message on may cause the
lamp to turn on as well.
If you must replace the fuel filler cap, replace it with a fuel filler
cap that is designed for your vehicle. The customer warranty may
be void for any damage to the fuel tank or fuel system if the
correct genuine Mazda fuel filler cap is not used.
WARNING: The fuel system may be under pressure. Remove
fuel filler cap slowly. Otherwise, fuel may spray out and injure
you or others.
WARNING: If you do not use the proper fuel filler cap,
excessive vacuum in the fuel tank may damage the fuel system
or cause the fuel cap to disengage in a collision, which may
result in personal injury.
Choosing the right fuel
Use only UNLEADED fuel or UNLEADED fuel blended with a maximum
of 10% ethanol. Your vehicle was not designed to run on E85 fuels that
are blended with a maximum of 85% ethanol. The use of leaded fuel is
prohibited by law and could damage your vehicle. Do not use fuel
containing methanol. It can damage critical fuel system components.
Your vehicle was not designed to use fuel or fuel additives with metallic
compounds, including manganese-based additives. Studies indicate that
these additives can cause your vehicle’s emission control system to
deteriorate more rapidly.
Repairs to correct the effects of using a fuel for which your vehicle was
not designed may not be covered by your warranty.

Octane recommendations
Your vehicle is designed to use
“Regular” unleaded gasoline with
pump (R+M)/2 octane rating of 87.
We do not recommend the use of
gasolines labeled as “Regular” that
are sold with octane ratings of 86 or lower in high altitude areas.
Do not be concerned if your engine sometimes knocks lightly. However, if
it knocks heavily under most driving conditions while you are using fuel
with the recommended octane rating, see your authorized dealer to
prevent any engine damage.
Fuel quality
If you are experiencing starting, rough idle or hesitation driveability
problems, try a different brand of unleaded gasoline. “Premium”
unleaded gasoline is not recommended for vehicles designed to use
“Regular” unleaded gasoline because it may cause these problems to
become more pronounced. If the problems persist, see your authorized
dealer.
Do not add aftermarket fuel additive products to your fuel tank. It
should not be necessary to add any aftermarket products to your fuel
tank if you continue to use high quality fuel of the recommended octane
rating. These products have not been approved for your engine and
could cause damage to the fuel system. Repairs to correct the effects of
using an aftermarket product in your fuel may not be covered by your
warranty.
Many of the world’s automakers approved the World-Wide Fuel Charter
that recommends gasoline specifications to provide improved
performance and emission control system protection for your vehicle.
Gasolines that meet the World-Wide Fuel Charter should be used when
available. Ask your fuel supplier about gasolines that meet the
World-Wide Fuel Charter.
Cleaner air
Mazda endorses the use of reformulated “cleaner-burning” gasolines to
improve air quality, per the recommendations in theChoosing the Right
Fuel section.
Running out of fuel
Avoid running out of fuel because this situation may have an adverse
effect 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. On restarting, cranking time will take a few seconds longer
than normal.
• Normally, adding 1 gallon (3.8L) of fuel is enough to restart the
engine. If the vehicle is out of fuel and on a steep grade, more than 1
gallon (3.8L) may be required.
• The
indicator may come on. For more information on the “check
engine” or the “service engine soon” indicator, refer to Warning lights
and chimes in theInstrument Cluster chapter.
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 fill-ups or fuel gauge readings are
NOT accurate as a measure of fuel economy. We do not recommend
taking fuel economy measurements during the first 1,000 miles
(1,600 km) of driving (engine break-in period). You will get a more
accurate measurement after 2,000 miles–3,000 miles
(3,000 km–5,000 km).
Filling the tank
When the fuel gauge indicates empty, there is still a small reserve of fuel
in the fuel system. When refueling your vehicle after the fuel gauge
indicates empty, you might not be able to refuel the full amount of the
advertised capacity of the fuel tank due to the empty reserve still
present in the tank. The amount of usable fuel in the empty reserve
varies and should not be relied upon to increase driving range.
For consistent results when filling the fuel tank:
• Turn the engine/ignition switch to the off position prior to refueling;
an error in the reading will result if the engine is left running.
• Allow no more than two automatic click-offs when filling.
• Always use fuel with the recommended octane rating.
• Use a known quality gasoline, preferably a national brand.
Your results will be most accurate if your filling method is consistent.
Calculating fuel economy
1. Fill the fuel tank completely and record the initial odometer reading (in miles or kilometers).
2008 Tribute Hybrid (thv)
Owners Guide (post-2002-fmt)
USA (fus)
Maintenance and Specifications
269

2. Each time you fill the tank, record the amount of fuel added (ingallons or liters).
3. After at least three to five tank fill-ups, fill the fuel tank and record the current odometer reading.
4. Subtract your initial odometer reading from the current odometer reading.
5. Follow one of the simple calculations in order to determine fuel economy:
Calculation 1: Divide total miles traveled by total gallons used.
Calculation 2: Multiply liters used by 100, then divide by total
kilometers traveled.
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, very hot or very cold temperatures give lower fuel
economy.
Driving style — good driving and fuel economy habits
Since it is able to operate in electric mode and to collect braking energy,
your hybrid vehicle will get better fuel economy in city driving than on
the highway. This is contrary to conventional vehicles. However, many of
the same actions that improve fuel economy in a conventional vehicle
will also improve fuel economy in this vehicle.
Give consideration to the lists that follow and you may be able to
improve your fuel economy.
Habits
• Avoid aggressive driving. Quick acceleration and deceleration decrease
fuel economy.
• Drive at a smooth, constant speed. Excessive variation in pedal input
causes more operating mode changes and reduces efficiency.
• Drive at reasonable speeds. Traveling at 60 mph [96 km/h] uses
approximately 20% less fuel than traveling at 70 mph [112 km/h]).
• Minimize A/C and defroster usage. Selecting defrost, or defrost/floor
mode on the climate control system will force the engine to run
continuously, which reduces fuel economy. Selecting AUTO will
typically force the engine to run continuously, unless ECON is
selected.
