Keep flames and sparks away from lead-acid battery cells and do not
allow metal tools to contact the positive (+) or negative (-) terminal of the
lead-acid battery when working near a lead-acid battery. Do not allow the
positive (+) terminal to contact the vehicle body.
Flames and sparks near lead-acid battery cells are dangerous. Hydrogen gas,
produced during normal lead-acid battery operation, could ignite and cause the
lead-acid battery to explode. An exploding lead-acid battery can cause serious burns
and injuries. Keep all flames including cigarettes and sparks away from lead-acid
battery cells.
Keep all flames and sparks away from lead-acid battery cells
because hydrogen gas is produced from le ad-acid battery cells while charging the
lead-acid battery or adding lead-acid battery fluid.

Do not jump-start a frozen lead-acid battery or one with a low fluid level.
Jump-starting a frozen lead-acid battery or one with a low fluid level is dangerous. It
may rupture or explode, causing serious injury.
Connect the negative cable to a good ground point away from the lead-acid
battery.
Connecting the end of the second jumper cable to the negative (–) terminal of the
depleted lead-acid battery is dangerous.
A spark could cause the gas around the lead-acid battery to explode and injure
someone.
Route the jumper cables away from parts that will be moving.
Connecting a jumper cable near or to moving part (cooling fans) is dangerous. The
cable could get caught when the hybrid system starts and cause serious injury.

Ta k i n g A c t i o n w i t hOverheating
If the engine coolant temperature
gauge indicates overheating and the
high engine coolant temperature
warning light is displayed, the vehicle
loses power or you hear a loud
knocking or pinging noise, the engine
is probably too hot.
WARNING
Pull over to a safe location, then
switch the vehicle power 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.

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.
