ignition), then turn the key toward
you and remove the key.
If your vehicle gets stuck in mud or snow
If your vehicle gets stuck in mud or snow, it may be rocked out by
shifting between forward and reverse gears, stopping between shifts in a
steady pattern. Press lightly on the accelerator in each gear.
Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Do not rock the vehicle for more than a minute or damage to the
transmission and tires may occur, or the engine may overheat.
FOUR-WHEEL DRIVE (4WD) OPERATION (IF EQUIPPED)WARNING: For important information regarding safe operation
of this type of vehicle, see Preparing to drive your vehicle in
this chapter.
Four–wheel drive (4WD) supplies power to all four wheels. 4WD should
not be operated on dry pavement; driveline damage may occur.
If equipped with the Electronic Shift 4WD System, and 4WD Low
is selected while the vehicle is moving above 3 mph (5 km/h), the
4WD system will not engage. This is normal and should be no
reason for concern. Refer toShifting to/from 4WD Low for proper
operation.

If your vehicle goes off the edge of the pavement
•If your vehicle goes off the edge of the pavement, slow down, but
avoid severe brake application, ease the vehicle back onto the
pavement only after reducing your speed. Do not turn the steering
wheel too sharply while returning to the road surface.
• It may be safer to stay on the apron or shoulder of the road and slow
down gradually before returning to the pavement. You may lose
control if you do not slow down or if you turn the steering wheel too
sharply or abruptly.
• It often may be less risky to strike small objects, such as highway
reflectors, with minor damage to your vehicle rather than attempt a
sudden return to the pavement which could cause the vehicle to slide
sideways out of control or roll over. Remember, your safety and the
safety of others should be your primary concern.
WARNING: Vehicles with a higher center of gravity such as
utility and four-wheel drive vehicles handle differently than
vehicles with a lower center of gravity. Utility and four-wheel
drive vehicles are not designed for cornering at speeds as high
as passenger cars any more than low-slung sports cars are
designed to perform satisfactorily under off-road conditions.
Avoid sharp turns, excessive speed and abrupt maneuvers in
these vehicles. Failure to drive cautiously could result in an
increased risk of loss of vehicle control, vehicle rollover,
personal injury and death.
If your vehicle gets stuck
If the vehicle is stuck it may be rocked out by shifting from forward and
reverse gears, stopping between shifts, in a steady pattern. Press lightly
on the accelerator in each gear.
Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Do not rock the vehicle for more than a few minutes or damage
to the transmission and tires may occur or the engine may
overheat. WARNING: Do not spin the wheels at over 35 mph (56 km/h).
The tires may fail and injure a passenger or bystander.

* Torque specifications are for nut and bolt threads free of dirt and
rust. Use only Mazda recommended replacement fasteners. WARNING: When a wheel is installed, always remove any
corrosion, dirt or foreign materials present on the mounting
surfaces of the wheel or the surface of the wheel hub, brake
drum or brake disc that contacts the wheel. Ensure that any
fasteners that attach the rotor to the hub are secured so they
do not interfere with the mounting surfaces of the wheel.
Installing wheels without correct metal-to-metal contact at the
wheel mounting surfaces can cause the wheel nuts to loosen
and the wheel to come off while the vehicle is in motion,
resulting in loss of control.
Note: If there is corrosion on the area where the wheel contacts the
hub, apply a thin film of grease or anti-seize compound on that area.
OVERHEATING
If the temperature gauge indicates overheating and you experience
power loss, you hear a loud knocking or pinging noise, the engine is
probably too hot.
If this happens:
1. Drive safely to the side of the road and park off the right-of-way.
2. Shift the automatic transmission into P (Park) or the manual transmission into the neutral position, and apply the parking brake.
3. Turn off the air conditioner.
WARNING: Steam from an overheated engine is dangerous. The
escaping steam could seriously burn you. Open the hood ONLY
after steam is no longer escaping from the engine.

4. Check whether coolant or steam is escaping from under the hood orfrom the engine compartment.
• If steam is coming from the engine compartment: do not go near
the front of the vehicle. Stop the engine, then turn the ignition switch
to the ON position without starting the engine. The radiator cooling
fans will start to cool the engine.
• If neither coolant nor steam is escaping: open the hood and idle
the engine until it cools. If this does not lower the temperature, stop
the engine and let it cool.
5. Check the coolant level. If it is low, look for leaks in the radiator hoses and connections, heater hoses and connections, radiator and
water pump.
If you find a leak or other damage, or if coolant is still leaking, stop the
engine and call an authorized dealer.
See Adding coolant in theMaintenance and Specifications section. If
you find no problems, the engine is cool and no leaks are obvious,
carefully add coolant as required.
WARNING: When the engine and radiator are hot, scalding
coolant and steam may shoot out under pressure and cause
serious injury. Do not remove the cooling system cap when the
engine and radiator are hot.
Note: If the engine continues to overheat or frequently overheats, have
the cooling system inspected. The engine could be seriously damaged
unless repairs are made.
JUMP STARTING
WARNING: The gases around the battery can explode if
exposed to flames, sparks, or lit cigarettes. An explosion could
result in injury or vehicle damage.
WARNING: Batteries contain sulfuric acid which can burn skin,
eyes and clothing, if contacted.
Do not attempt to push-start your automatic transmission
vehicle. Automatic transmissions do not have push-start
capability. Attempting to push-start a vehicle with an automatic
transmission may cause transmission damage.

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 “FULL COLD” level. 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.
Note: The 3.0L and 4.0L V6 engines use the overflow system, and the
2.3L I4 engines use the degas system.
WARNING: To avoid scalding hot steam or coolant from being
released from the engine cooling system, never remove the
reservoir cap while the engine is running or hot. Failure to
follow this warning may result in damage to the engine’s cooling
system and possible severe personal injury.
1. Before you remove the cap, turn the engine off and let it cool.
2. When the engine is cool, wrap a thick cloth around the cap. Slowly turn cap counterclockwise 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 thecloth 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 Checking engine coolant . 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
Not all coolant recycling processes produce coolant which meets Mazda
specification. Use of a recycled engine coolant which does not meet
Mazda specifications may harm engine and cooling system components.
Always dispose of used automotive fluids in a responsible 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.
