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

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.
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.
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.
