Warning and Cautions forUsing the Selector Lever
WARNING
Always apply the parking brake when
the selector lever is in the P position.
When parking the vehicle, only shifting
the selector lever to the P position is
dangerous as the vehicle may move
unexpectedly and result in an accident.
Do not move the selector lever from
the N or P position while the engine
speed is high.
Otherwise, the vehicle will move
suddenly which could lead to an
unexpected accident.
When operating the selector lever,
shift the selector lever with the brake
pedal firmly depressed and the
vehicle completely stopped.
Operating the selector lever while the
vehicle is moving could lead to an
unexpected accident.
Do not shift the selector lever with the
accelerator pedal depressed when the
selector lever is in the P or N position.
Always operate the selector lever with
the brake pedal depressed when the
selector lever is in the P or N position.
Otherwise, the vehicle will suddenly
accelerate which could lead to an
accident.
Do not shift the selector lever to the N
position while driving.
Otherwise, it could result in the loss of
the engine braking power and cause
an accident.
Do not depress the accelerator pedal
unnecessarily while the vehicle is
stopped.
If the accelerator pedal is mistakenly
depressed when the se lector lever is in
a position other than the P or N
position, the vehicle could suddenly
accelerate resulting in an accident.
After stopping the vehicle, check the
shift position indication in the
instrument cluster before
re-accelerating.
If the vehicle were to move
unexpectedly, it could lead to an
accident.
Do not allow the vehicle to move in
reverse on an upslope while the
selector lever is in forward drive, or
move forward on a downslope while
the selector lever is in reverse drive.
Otherwise, the engine could stop,
making the steering wheel difficult to
control, which could result in an
accident.
CAUTION
 When visually checking at the rear of
the vehicle while reversing the
vehicle, your body twists around to
the rear. Be careful and make sure
that the brake pedal can be firmly
depressed.
 Completely stop the vehicle before
shifting the select or lever to the P
position. If the selector lever is
shifted to P position before the
vehicle is completely stopped,
unnecessary force will be applied to
the transmission which could cause
damage.

Warnings and Cautionsfor Using the FuelRequirements
CAUTION
 USE ONLY UNLEADED FUEL.
Leaded fuel is harmful to the catalytic
converter and oxygen sensors and
will lead to deterioration of the
emission control system and or
failures.
 This vehicle can only use oxygenated
fuels containing no more than 10 %
ethanol by volume. Damage to the
vehicle may occur when ethanol
exceeds this recommendation, or if
the gasoline contains any methanol.
Stop using gasohol of any kind if your
vehicle engine is performing poorly.
 Never add fuel system additives
other than a Mazda genuine
product, otherwise the emission
control system could be damaged.
Consult an Authorized Mazda Dealer
for details.
Emission Control System
This vehicle is equipped with an
emission control system (the catalytic
converter is part of this system) that
enables the vehicle to comply with
existing exhaust emissions
requirements.
NOTE
Under U.S. federal law, any
modification to the
original-equipment emission control
system before the first sale and
registration of a vehicle is subject to
penalties. In some states, such modification made on a used vehicle
is also subject to penalties.
While the engine is off, the sound of
a valve opening and closing can be
heard at the rear of the vehicle,
however this does not indicate an
abnormality. The vehicle has a
self-checking device and it operates
while the engine is off.

Winter Driving
Carry emergency gear, including tire
chains, window scraper, flares, a small
shovel, jumper cables, and a small bag
of sand or salt.
Ask an Authorized Mazda Dealer to
check the following:
Have the proper ratio of antifreeze in
the radiator.
Refer to Inspecting the Coolant on
page 9-14.
Inspect the battery and its cables.
Cold reduces battery capacity.
Use an engine oil appropriate for the
lowest ambient temperatures that
the vehicle will be driven in (page
9-18).
Inspect the ignition system for
damage and loose connections.
Use washer fluid made with
antifreeze―but do not use engine
coolant antifreeze for washer fluid
(page 9-17).
When driving on ice or in water, snow,
mud, sand, or similar hazards:
Be cautious and allow extra distance
for braking.
Avoid sudden braking and sudden
maneuvering.
Do not pump the brakes. Continue
to press down on the brake pedal.
Refer to Antilock Brake System (ABS)
on page 5-84.
If you get stuck, select a lower gear
and accelerate slowly. Do not spin
the rear wheels.
For more traction in starting on
slippery surfaces such as ice or
packed snow, use sand, rock salt,
chains, carpeting, or other nonslip
material under the rear wheels.
NOTE
Remove snow before driving. Snow
left on the windshield is dangerous
as it could obstruct vision.
Do not apply excessive force to a
window scraper when removing ice
or frozen snow on the mirror glass
and windshield.
Never use warm or hot water for
removing snow or ice from windows
and mirrors as it could result in the
glass cracking.
Drive slowly. Braking performance
can be adversely affected if snow or
ice adheres to the brake
components. If this situation occurs,
drive the vehicle slowly, releasing the
accelerator pedal and lightly applying
the brakes several times until the
brake performance returns to
normal.

Ta k i n g A c t i o n w i t hOverheating
If the engine coolant temperature
gauge indicates overheating and the
high engine coolant temperature
warning light is displayed, the vehicle
loses power or you hear a loud
knocking or pinging noise, the engine
is probably too hot.
WARNING
Pull over to a safe location, then
switch the vehicle power off and
make sure the fan is not running
before attempting to work near the
cooling fan.
Working near the cooling fan when it is
running is dangerous. The fan could
continue running indefinitely even if
the engine has stopped and the engine
compartment temperature is high. You
could be hit by the fan and seriously
injured.
Do not remove either
cooling system cap when the engine
and radiator are hot.
When the engine and radiator are hot,
scalding coolant and steam may shoot
out under pressure and cause serious
injury.
Open the hood ONLY after steam is
no longer escaping from the engine.
Steam from an overheated engine is
dangerous. The escaping steam could
seriously burn you.

1. Drive safely to the side of the road and park off the right-of-way.
2. Shift into park (P).
3. Apply the parking brake.
4. Turn off the air conditioner.
5. Check whether coolant or steam is escaping from the engine
compartment.

If steam is coming from the engine
compartment:
Do not go near the front of the
vehicle. Stop the engine.
Wait until the steam dissipates,
then open the hood and start the
engine.

If neither coolant nor steam is
escaping:
Open the hood and idle the engine
until it cools.
CAUTION
If the cooling fan does not operate
while the engine is running, the
engine temperature will increase.
Stop the engine and call an
Authorized Mazda Dealer.
6. Make sure the cooling fan is operating, then turn off the engine
after the temperature has
decreased.
7. When cool, check the coolant level. If it is low, look for coolant leaks
from the radiator and hoses.
