CAUTION
In addition, the
effectiveness of the
braking may diminish so you may
need to depress the brake pedal
more strongly than normal to stop
the vehicle.

▼ Electronic Brake Force Distribution
System Warning
If the electronic brake force
distribution control unit determines
that some components are operating
incorrectly, the control unit may
illuminate the brake system warning
light and the ABS warning light
simultaneously. The problem is likely to
be the electronic brake force
distribution system.
WARNING
Do not drive with both the brake
system warning light and ABS warning
light illuminated. Have the vehicle
towed to an Authorized Mazda
Dealer to have the brakes inspected as
soon as possible:
Driving when the brake system warning
light and ABS warning light are
illuminated simultaneously is
dangerous.
When both lights are illuminated, the
rear wheels could lock more quickly in
an emergency stop than under normal
circumstances.
▼
Charging System Warning
Indication/Warning Light
If the warning light illuminates while
driving, it indicates a malfunction of
the alternator or of the charging
system.
Drive to the side of the road and park
off the right-of-way. Consult an
Authorized Mazda Dealer.
CAUTION
Do not continue driving when the
charging system warning light is
illuminated because the engine could
stop unexpectedly.
▼Engine Oil Warning Indication/
Warning Light
This warning light indicates low engine
oil pressure.
CAUTION
Do not run the engine if the oil
pressure is low. Otherwise, it could
result in extensive engine damage.
If the light illuminates or the warning
indication is displayed while driving:
1. Drive to the side of the road and
park off the right-of-way on level
ground.
2. Turn off the engine and wait 5
minutes for the oil to drain back
into the oil pan.

3. Inspect the engine oil level (page6-18). If it's low, add the
appropriate amount of engine oil
while being careful not to overfill.
CAUTION
Do not run the engine if the oil
level is low. Otherwise, it could
result in extensive engine damage.
4. Start the engine and check the warning light.

If the light remains illuminated even
though the oil level is normal or after
adding oil, stop the engine
immediately and have your vehicle
towed to an Authorized Mazda Dealer.
▼ High Engine Coolant Temperature
Warning Indicat ion
Displays if the engine coolant
temperature has increased excessively.
“Elevated Engine Coolant Temp. Drive
Slowly” displayed
Drive slowly to reduce engine load
until you can find a safe place to stop
the vehicle and wait for the engine to
cool down.
“Excessive Engine Coolant Temp. Stop
the Vehicle in a Safe Location”
displayed
This indicates the possibility of
overheating. Park the vehicle in a safe
place immediately and stop the
engine.
Refer to Overheating on page 7-17.
CAUTION
Do not drive the vehicle with the high
engine coolant temperature warning
light illuminated. Otherwise, it could
result in damage to the engine.
▼ Power Steering Malfunction
Indication/Indicator Light
The message is displayed if the electric
power steering has a malfunction.
If the message is displayed, stop the
vehicle in a safe place and do not
operate the steering wheel. There is no
problem if the indication turns off
when the engine is restarted after
some time has passed. If the indication
displays even after the engine is
restarted, contact an Authorized
Mazda Dealer if the message is
displayed continuously.
NOTE
If the message is displayed, the
power steering will not operate
normally. In this case, the steering
wheel can still be operated,
however, the operation may feel
heavy compared to normal, or the
steering wheel could vibrate when
turning.
Repeatedly jerking the steering
wheel left and right while the vehicle
is stopped or moving extremely
slowly will cause the power steering
system to go into protective mode
which will make the steering feel
heavy, but this does not indicate a
problem. If this occurs, park the
vehicle safely and wait several
minutes for the system to return to
normal.
