Only a trained service technician with the proper
knowledge and tools should inspect, test, or replace
the hybrid battery. See your dealer/retailer if the
hybrid battery needs service. The dealer/retailer
has information on how to recycle the hybrid
battery. There is also information available at
http://www.recyclemybattery.com.
If an airbag inflates or the vehicle has been in a crash,
the vehicle's sensing system might command the
automatic hybrid battery disconnect to open. See
Replacing Restraint System Parts After a Crash
on
page 2‑3for more information.
{DANGER:
Battery posts, terminals, and related accessories
contain lead and lead compounds, chemicals
known to the State of California to cause cancer
and reproductive harm. Wash hands after
handling.
Vehicle Storage
{WARNING:
Batteries have acid that can burn you and gas
that can explode. You can be badly hurt if you are
not careful. See Jump Starting
on page 6‑18
for tips on working around a battery without
getting hurt.
Infrequent Usage: Remove the 12‐volt battery black,
negative (−) cable from the battery to keep the battery
from running down.
Extended Storage: Remove the 12‐volt battery black,
negative (−) cable from the battery or use a battery
trickle charger.
Remember to reconnect the battery when ready to drive
the vehicle.

Jump Starting
{WARNING:
Personal injury, death, or damage to the vehicle
can result if you try jump starting or using a
battery charger on the high voltage hybrid battery.
Use only the 12-volt battery for jump starting and
charging.
If the vehicle's 12‐volt battery has run down, you may
want to use another vehicle and some jumper cables to
start your vehicle. Use the following steps to do it safely.
{WARNING:
Batteries can hurt you. They can be dangerous
because:
.They contain acid that can burn you.
.They contain gas that can explode or ignite.
.They contain enough electricity to burn you.
If you do not follow these steps exactly, some or
all of these things can hurt you.
Notice: Ignoring these steps could result in costly
damage to the vehicle that would not be covered by
the warranty.
Trying to start the vehicle by pushing or pulling it
will not work, and it could damage the vehicle.
1. Check the other vehicle. It must have a 12‐volt battery with a negative ground system.
Notice: If the other vehicle's system is not a 12-volt
system with a negative ground, both vehicles can
be damaged. Only use vehicles with 12-volt systems
with negative grounds to jump start your vehicle.
6-18

2. Get the vehicles close enough so the jumpercables can reach, but be sure the vehicles are not
touching each other. It could cause a ground
connection you do not want. You would not be able
to start your vehicle, and the bad grounding could
damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake firmly on both vehicles involved
in the jump start procedure. Put the automatic
transmission in P (Park) or a manual transmission
in N (Neutral) before setting the parking brake.
If you have a four-wheel-drive vehicle, be sure the
transfer case is in a drive gear, not in N (Neutral).
Notice: If you leave the radio or other accessories
on during the jump starting procedure, they could
be damaged. The repairs would not be covered by
the warranty. Always turn off the radio and other
accessories when jump starting the vehicle. 3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the
cigarette lighter or the accessory power outlets.
Turn off the radio and all the lamps that are not
needed.
This avoids sparks and helps save both batteries.
It could save the radio!
4. Open the hood on the other vehicle and locate the positive (+) and negative (−) terminal locations on
that vehicle.
Your vehicle has a remote positive (+) and a
remote negative (−) jump starting terminal.
You should always use these remote terminals
instead of the terminals on the battery.
6-19

8. Do not let the other end touch metal. Connect it tothe positive (+) terminal of the good battery. Use a
remote positive (+) if the vehicle has one.
9. Now connect the black negative (−) cable to the negative (−) terminal of the good battery. Use a
remote negative (−) if the vehicle has one.
Do not let the other end touch anything until the
next step. The other end of the negative (−) cable
does not go to the dead battery. It goes to a heavy,
unpainted metal engine part or to the remote
negative (−) terminal on the vehicle with the dead
battery. 10. Connect the other end of the negative (−) cable to
the remote negative (−) terminal, on the vehicle
with the dead battery.
11. Now start the vehicle with the good battery and run the engine for a while.
12. Try to start the vehicle that had the dead battery. If it will not start after a few tries, it probably needs
service.
Notice: If the jumper cables are connected or
removed in the wrong order, electrical shorting may
occur and damage the vehicle. The repairs would
not be covered by the vehicle warranty. Always
connect and remove the jumper cables in the
correct order, making sure that the cables do not
touch each other or other metal.
