2005 MAZDA MODEL RX 8 check engine

Black plate (121,1)
NOTE
lWhen DSC is on and you attempt to
free the vehicle when it is stuck, or
drive it out of freshly fallen snow,
the TCS (part of the DSC system)
will activate. Depressing the
accelerator will not increase engine
power and freeing the vehicle may
be difficult.
When this happens, turn off the TCS/
DSC.
lIf the TCS/DSC is off when the
engine is turned off, it automatically
activates when the ignition switch is
turned on.
lLeaving the TCS/DSC on will
provide the best stability. When the
TCS/DSC is off, the TCS/DSC does
not activate but the brake LSD
function remains.
lIf the DSC OFF switch is pressed
and held for a second or more, the
TCS/DSC system may become
inoperative due to the system
detecting switch trouble. If the TCS/
DSC system becomes inoperative,
the TCS/DSC and the DSC OFF
indicator lights illuminate
simultaneously. In this case, turn off
the engine and restart it to restore the
TCS/DSC.
Tire Pressure Monitoring
System
í
The tire pressure monitoring system
(TPMS) monitors the pressure for each
tire.
If tire pressure is too low or too high in
one or more tires, the system will inform
the driver via the warning light in the
instrument panel and by the warning beep
sound.
The tire pressure sensors installed on each
wheel send tire pressure data by radio
signal to the receiver unit in the vehicle.
Tire pressure sensors
TPMS does not alleviate your need to
check the pressure and condition of all
four tires before you drive each day.

qFuel Gauge
The fuel gauge shows approximately how
much fuel is in the tank. We recommend
keeping the tank over 1/4 full. When the
low fuel warning light illuminates or
when the needle is near E, refuel as soon
as possible.
Low fuel warning light
qEngine Oil Pressure Gauge
Engine oil pressure is normal when the
engine oil pressure gauge needle points
halfway between L and H with the engine
running.
If the needle on the gauge doesn't move
after starting the engine, follow steps 1
through 3.If the engine oil pressure gauge moves to
L (low) while you are driving, drive to the
side of the road and park off the right-of-
way. Set the parking brake. Then follow
steps 1 through 3.
1. Turn off the engine and inspect the
engine oil level (page 8-13). If it's low,
add oil.
2. Start the engine.
3. If the needle still doesn't move, have
your vehicle checked at an Authorized
Mazda Dealer.
CAUTION
Don't run the engine if the oil pressure
is low. It could result in extensive
engine damage.
NOTE
The Mazda RX-8 requires regular
checking of the engine oil level. The
compact, high performance RENESIS
rotary engine in your vehicle consumes
a small amount of engine oil due to its
structural design. An oil pump
optimizes the amount of oil injected to
lubricate the rotor seals in the
combustion cycle. Although your
vehicle is equipped with an engine oil
level warning light and an engine oil
pressure gauge, it is best to keep the
engine oil level in the range between
full and low by checking the oil
dipstick regularly. Mazda recommends
checking the oil level at every second
fuel filling. The oil consumption of the
engine depends on engine speed and
engine load. Under extreme driving
conditions, oil consumption can be
higher.

Operating Tips
qOperating the Climate Control
System
Operate the climate control system with
the engine running.
NOTE
To prevent the battery from being
discharged, do not leave the fan control
dial on for a long period of time when
the engine is not running.
qClearing the Air Inlet
Clear all obstructions like leaves, snow
and ice from the hood and the air inlet in
the cowl grille to improve the system
efficiency.
qFoggy Windows
The windows may fog up easily in humid
weather. Use the climate control system to
defog the windows.
To help defog the windows, operate the
air conditioner to dehumidify the air.
qOutside/Recirculated Air Position
Use the outside air position in normal
conditions. The recirculated air position
should be used only when driving on
dusty roads or for quick cooling of the
interior.
qParking in Direct Sunlight
If the vehicle has been parked in direct
sunlight during hot weather, open the
windows to let warm air escape, then run
the climate control system.
qNot Using for a Long Period
Run the air conditioner about 10 minutes
at least once a month to keep internal
parts lubricated.

Weather Gets Hot
Have the air conditioner checked before
the weather gets hot. Lack of refrigerant
may make the air conditioner less
efficient. Consult an Authorized Mazda
Dealer for refrigerant inspection.
The air conditioner is filled with
HFC134a (R134a), a refrigerant that will
not damage the ozone layer.
If the air conditioner is low on refrigerant
or has a malfunction, consult an
Authorized Mazda Dealer.
qReplacement of the Cabin Air
Filter

Overheating
If the temperature gauge indicates
overheating, the vehicle loses power, or
you hear a loud knocking or pinging
noise, the engine is probably too hot.
WARNING
Electrical Fan and Engine
Inspection:
Working near the electrical cooling
fan when it is running is dangerous.
You could be hit by the fan and
seriously injured. Turn off the ignition
switch and make sure the fan is not
running before attempting to work
near the electrical cooling fan.
Cooling System Cap:
When the engine and radiator are hot,
scalding coolant and steam may shoot
out under pressure and cause serious
injury. Don't remove the cooling
system cap when the engine and
radiator are hot.
Steam from Overheated Engine:
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.
NOTE
Once the engine coolant exceeds a
preset temperature, an electrical cooling
fan turns on. It will continue running
for about 10 minutes after the ignition
switch is turned to off.
If the temperature gauge indicates
overheating:
1. Drive safely to the side of the road and
park off the right-of-way.
2. Put a vehicle with an automatic
transmission in park (P), a manual
transmission in neutral.
Apply the parking brake.
3. Turn off the air conditioner.
4. Check whether coolant or steam is
escaping from under the hood or from
the engine compartment.
If steam is coming from the engine
compartment:
Don't 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.
