Route the jumper cables away from parts that will be moving:
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.
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).
Booster batteryDischarged battery
Jumper cables
Connect cables in numerical order
and disconnect in reverse order.
1. Remove the battery cover.
2. Make sure the booster battery is 12 Vand that its negative terminal is
grounded.
3. If the booster battery is in another vehicle, do not allow both vehicles to
touch. Turn off the engine of the
vehicle with the booster battery and all
unnecessary electrical loads in both
vehicles.
4. Connect the jumper cables in the exact
sequence as in the illustration.
•Connect one end of a cable to the
positive terminal on the discharged
battery (1).
•Attach the other end to the positive
terminal on the booster battery (2).
•Connect one end of the other cable
to the negative terminal of the
booster battery (3).
•Connect the other end to the ground
point indicated in the illustration
away from the discharged battery
(4).
5. Start the engine of the booster vehicle and run it a few min utes. Then start the
engine of the other vehicle.
6. When finished, carefully disconnect the cables in the reverse order
described in the illustration.

Overheating
If the temperature gauge indicates
overheating or the high engine coolant
temperature warning light turns on, the
vehicle loses power, or you hear a loud
knocking or pinging noise, the engine is
probably too hot.
WA R N I N G
Pull over to a safe location, then switch
the ignition 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 temperature gauge indicates
overheating or the high engine coolant
temperature warning light turns on:

1. Drive safely to the side of the road and
park off the right-of-way.
2. Shift into park (P).
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.

If you find a leak or other damage, or if
coolant is still leaking:
Stop the engine and call an Authorized
Mazda Dealer.

If you find no problems, the engine is
cool, and no leaks are obvious:
Carefully add coolant as required (page
6-18).
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.
