Taking Action with Depleted Lead-acid Battery
The lead-acid battery might be depleted if the following conditions occur.
The hybrid system does not start.The selector lever cannot be shifted to a position other than P.The horn sound is weak or it does not sound.The brightness of the lights is extremely low.
Using commercially available booster cables, connect the lead-acid battery of the
booster vehicle’s battery to the lead-acid battery of your vehicle and start the hybrid
system.
Jump-starting is dangerous if done incorr ectly. Therefore, follow the procedure
carefully. If you feel unsure about jump-s tarting , we strongly recommend that you
have a competent service technician do the work.
WARNING
Read the following precautions carefully before using the lead-acid
battery or inspecting to ensure safe and correct handling.
Always wear eye protection when working near the lead-acid battery.
Working without eye protection is dangerous. Lead-acid battery fluid contains
SULFURIC ACID which could cause blindne ss if splashed into your eyes. Also,
hydrogen gas produced during normal lead-acid battery operation, could ignite and
cause the lead-acid battery to explode.
Wear eye protection and protective gloves to prevent contact with
lead-acid battery fluid.
Spilled lead-acid battery fluid is dangerous.
Lead-acid battery fluid contains SULFURIC ACID which could cause serious injuries if
it gets in eyes, or on the skin or clothing. If this happens, immediately flush your eyes
with water for 15 minutes or wash your skin thoroughly and get medical attention.
Always keep lead-acid batteries out of the reach of children.
Allowing children to play near lead-acid batteries is dangerous. Lead-acid battery
fluid could cause serious injuries if it gets in the eyes or on the skin.

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

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.
