Starting a Flooded Engine
If the engine fails to start, it may be
flooded (excessive fuel in the engine).
Follow this procedure:
1. If the engine does not start within five
seconds on the first try, wait ten
seconds and try again.
2. Make sure the parking brake is on.
3. Depress the accelerator all the way and
hold it there.
4. Depress the clutch pedal (Manual
transaxle) or the brake pedal
(Automatic transaxle), then press the
push button start. If the engine starts,
release the accelerator immediately
because the engine will suddenly rev
up.
5. If the engine fails to start, crank it
without depressing the accelerator.
If the engine still does not start using the
above procedure, have your vehicle
inspected by an Authorized Mazda
Dealer.
Push-Starting
Do not push-start your Mazda.
WARNING
Never tow a vehicle to start it:
Towing a vehicle to start it is
dangerous. The vehicle being towed
could surge forward when its engine
starts, causing the two vehicles to
collide. The occupants could be
injured.
CAUTION
Do not push-start a vehicle that has
a manual transaxle. It can damage
the emission control system.
NOTE
You cannot start a vehicle with an automatic
transaxle by pushing it.

Overheating
If the High engine coolant temperature
warning light illuminates, the vehicle
loses power, or you hear a loud knocking
or pinging noise, the engine is probably
too hot.
WARNING
Switch the ignition to 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.
If the High engine coolant temperature
warning light illuminates:
1. Drive safely to the side of the road and
park off the right-of-way.2. Put a vehicle with an automatic
transaxle in park (P), a manual
transaxle in neutral.
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.

qIf the brake system warning light
illuminates
When the light turns on
If the brake system warning light remains
turned on even though the electric parking
brake is released, the brake fluid may be
low or there could be a problem with the
brake system. Park the vehicle in a safe
place immediately and contact an
Authorized Mazda Dealer.
When the light is flashing
The light flashes if the electric parking
brake has a malfunction.

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.
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.
qIf the ABS warning light illuminates
If the ABS warning light stays on while
you're driving, the ABS control unit has
detected a system malfunction. If this

as if the vehicle had no ABS.
Should this happen, consult an Authorized
Mazda Dealer as soon as possible.
NOTE
lWhen the engine is jump-started to charge
the battery, uneven rpm occurs and the ABS
warning light may illuminate. If this occurs,
it is the result of the weak battery and does
not indicate an ABS malfunction.
Recharge the battery.
lThe brake assist system does not operate
while the ABS warning light is illuminated.
