2011 MAZDA MODEL RX 8 check engine light

Black plate (151,1)
Even if the light turns off have your brake
system inspected as soon as possible by
an Authorized Mazda Dealer.
NOTE
Having to add brake fluid is sometimes an
indicator of leakage. Consult an Authorized
Mazda Dealer as soon as possible even if the
brake light is no longer illuminated.
WARNING
Do not drive with the brake system
warning light illuminated. Contact an
Authorized Mazda Dealer to have the
brakes inspected as soon as possible:
Driving with the brake system
warning light illuminated is
dangerous. It indicates that your
brakes may not work at all or that
they could completely fail at any
time. If this light remains
illuminated, after checking that the
parking brake is fully released, have
the brakes inspected immediately.
qAnti-Lock Brake System (ABS)
The ABS control unit continuously
monitors the speed of each wheel. If one
is about to lock up, the ABS responds by
automatically releasing and reapplying
that wheel's brake.
The driver will feel a slight vibration in
the brake pedal and may hear a chattering
noise from the brake system. This is
normal when the ABS operates. Continue
to depress the brake pedal without
pumping the brakes.
WARNING
Do not rely on ABS as a substitute for
safe driving:
The ABS cannot compensate for
unsafe and reckless driving, excessive
speed, tailgating (following another
vehicle too closely), driving on ice and
snow, and hydroplaning (reduced tire
friction and road contact because of
water on the road surface). You can
still have an accident.
NOTE
lBraking distances may be longer on loose
surfaces (snow or gravel, for example)
which usually have a hard foundation. A
vehicle with a normal braking system may
require less distance to stop under these
conditions because the tires will build up a
wedge of surface layer when the wheels
skid.
lThe sound of the ABS operating may be
heard when starting the engine or
immediately after starting the vehicle.
However, it does not indicate a malfunction.
qABS Warning Light
The warning light stays on for a few
seconds when the ignition is switched
ON.

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, 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.
If the light flashes continuously
If the warning light continues to flash, do
not drive at high speeds, drive the vehicle
at low engine rpm, and have an
Authorized Mazda Dealer inspect the
system.
NOTE
If the engine is turned off while the oil level
indicator is flashing due to a system
malfunction, it may take a few minutes until the
indicator starts flashing again after the engine
is started.
qEngine Coolant Level Warning Light
This warning light indicates low engine
coolant level.If the light illuminates while driving:
1. Drive to the side of the road and park
off the right-of-way.
2. Turn off the engine and inspect the
engine coolant level (page 8-14). If it's
low, add engine coolant.
3. Check the light.
If the light remains illuminated even after
you add engine coolant, have your vehicle
towed to an Authorized Mazda Dealer.
CAUTION
Don't run the engine if the engine
coolant level is low. It could result in
extensive engine damage.
qCheck Engine Light
This indicator light illuminates when the
ignition is switched ON and turns off
when the engine is started.
If this light illuminates while driving, the
vehicle may have a problem. It is
important to note the driving conditions
when the light illuminated and consult an
Authorized Mazda Dealer.
The check engine light may illuminate in
the following cases:
lThe fuel tank level being very low or
approaching empty.
lThe engine's electrical system has a

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 with the ignition switched ON
when the engine is not running.
qClearing the Air Inlet
Clear all obstructions such as 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.
NOTE
The air conditioner may be used along with the
heater to dehumidify the air.
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.
qCheck the Refrigerant before the
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
If your vehicle is equipped with an air
filter for the air conditioner, it is necessary
to change the filter periodically as
indicated in scheduled maintenance (page

qRecommended Oil
Use SAE 5W-20 engine oil.
Oil container labels provide important
information.
A chief contribution this type of oil makes
to fuel economy is reducing the amount of
fuel necessary to overcome engine
friction.
