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
Cooling Fan and EngineInspection:
Inspecting the engine with the ignition
switch in the ON position is
dangerous. The cooling fan could turn
on unexpectedly even when the engine
isn't running. You could be seriously
injured by the fan. Turn the ignition
switch off and remove the key from the
ignition switch when you inspect the
engine.
Cooling System Caps:
When the engine and radiator are hot,
scalding coolant and steam may shoot
out under pressure and cause serious
injury. Don't remove either 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.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
transaxle in park (P), a manual
transaxle 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 enginecompartment:
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 isescaping:
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.
5. Make sure the cooling fan is operating,
then turn off the engine after the
temperature has decreased.
6. When cool, check the coolant level.
If it's low, look for coolant leaks from
the radiator and hoses.

If you find no problems, the engine iscool, and no leaks are obvious:
Carefully add coolant as required (page
8-12).
CAUTION
If the engine continues to overheat or
frequently overheats, have the cooling
system inspected. The engine could be
seriously damaged unless repairs are
made. Consult an Authorized Mazda
Dealer.

Starting a Flooded Engine
If the engine fails to start, it may be
flooded (excessive fuel in the engine).
Follow this procedure:
1. Depress the accelerator all the way and
hold it there.
2. Turn the ignition switch to the START
position and hold it there—for up to 10
seconds. If the engine starts, release the
key and accelerator immediately
because the engine will suddenly rev
up.
3. If the engine fails to start, crank it
without depressing the accelerator—for
up to 10 seconds.

WARNING
Low Fluid Level or Frozen Battery:
Jump-starting a frozen battery or one with a low fluid level is dangerous. It may
rupture or explode, causing serious injury.
Don't jump-start a frozen battery or one with a low fluid level.
Connecting to Negative Terminal:
Connecting the end of the second cable to the negative () terminal of the discharged
battery is dangerous.
A spark could cause the gas around the battery to explode and injure someone.
Connect the cable to a point away from the battery.
Connecting Jumper Cable to Moving Parts:
Connecting a jumper cable near or to moving parts (cooling fans, belts) is dangerous.
The cable could get caught when the engine starts and cause serious injury. Never
connect a jumper cable to or near any part that moves.
CAUTION
Use only a 12 V booster system. You can damage a 12 V starter, ignition system, and
other electrical parts beyond repair with a 24 V power supply (two 12 V batteries in
series or a 24 V motor generator set).
1. Make sure the booster battery is 12 V
and that its negative terminal is
grounded.
2. If the booster battery is in another
vehicle, don't allow the vehicles to
touch. Turn off the engine of the
vehicle with the booster battery and all
unnecessary electrical loads in both
vehicles.
3. Connect the jumper cables in the exact
sequence as in the illustration.
lConnect one end of a cable to the
positive terminal on the discharged
battery (1).
lAttach the other end to the positive
terminal on the booster battery (2).
lConnect one end of the other cable
to the negative terminal of the
booster battery (3).

lConnect the other end to a solid,
stationary, exposed metallic point
(for example, the strut mounting
bolt) away from the discharged
battery (4).
Connect cables in
numerical order and
disconnect in reverse
order.

4. Start the engine of the booster vehicle
and run it a few minutes. Then start the
engine of the other vehicle.
5. When finished, carefully disconnect the
cables in the reverse order described in
Step 3.
Push-Starting
WARNING
Towing 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. Never tow a vehicle to start it.
You can't start a vehicle with an automatic
transaxle by pushing it.
CAUTION
You shouldn't push-start a vehicle that
has a manual transaxle. It can damage
the emission control system.
