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
War n in g I nd ic at 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 7-21.
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.
