WARNING: On vehicles equipped with the high voltage system, you must thoroughly read and follow all High Voltage Safety procedures. In addition, before performing any diagnostic or service procedure near a high voltage component, you must perform the High Voltage Power Down. Failure to follow these instructions may result in possible serious or fatal injury Service Precautions

WARNING: Review all safety precautions and warnings in the battery system section. Battery Charging
- Do not jump start a frozen battery.
- Do not jump start a maintenance-free battery (if equipped) when indicator dot is yellow or a bright color.
- Do not jump start a vehicle when the battery fluid is below the top of lead plates.
- Do not allow jumper cable clamps to touch each other when connected to a booster source.
- Do not expose battery to or near open flame.
- Remove metallic jewelry worn on hands or wrists to avoid injury by accidental arcing of battery current.
- When using a high-output boosting device, do not allow battery voltage to exceed 16 volts. Refer to instructions provided with device being used.

Failure to follow these instructions may result in personal injury.

CAUTION: When using another vehicle as a booster, do not allow vehicles to touch. Electrical systems can be damaged on either vehicle.

TO JUMP START A DISABLED VEHICLE:

This Hybrid vehicle is equipped with both a 12 Volt battery and a high voltage battery. Either battery may become discharged and cause a no crank condition as a result of low voltage.

If the 12 Volt battery state of charge is to low and the engine will not crank, the 12 Volt battery light located in the cluster, may illuminate. If this occurs refer to "Jump-Starting - 12 Volt Battery".

If the high voltage battery state of charge is too low and the engine will not crank, the navigation radio displays a "Charge Insufficient" message. If this occurs refer to "Jump Assist Procedure - High Voltage Battery".

Jump Assist Procedure - High Voltage Battery






NOTE: When running the Jump Assist mode with the scan tool, ensure the High Voltage Battery contactors are in the close positions. Using the scan tool view the High Voltage Battery contactors status in the BPCM. If the High Voltage Battery contactors are opened, the jump assist will not operate. If this happens, cycle the ignition key from off and on without an attempted crank.


The "Jump Assist" procedure allows you to charge the high voltage battery using the 12 Volt battery system. The navigation radio guides you through the "Jump Assist" procedure.

This message indicates that the vehicle is in "Jump Assist" mode, and can be charged by following the "Jump Assist" procedure. You have approximately 15 minutes to connect a 12 Volt battery charger and begin charging the system. If you are unable to connect a 12 Volt battery charger within 15 minutes, turn the ignition key to the START position to re-initiate "Jump Assist" mode.

NOTE:
- depending on the high voltage battery state of charge, it may take up to 60 minutes for the system to become adequately charged to start the engine.
- there are remote battery posts located under the hood that are used to assist in the "Jump Assist" procedure.
- a second running vehicle may be used in this "Jump Assist" procedure provided the generator output is a minimum of 125 amps.

WARNING:
- a battery generates hydrogen gas which is flammable and explosive. Keep flame or spark away from the vent holes. Do Not use a booster battery or any other booster source with a nominal voltage output that exceeds 12 Volts.
- battery fluid is a corrosive acid solution; do not allow battery fluid to contact eyes, skin or clothing. If acid splashes in eyes or on skin, flush the contaminated area immediately with large quantities of water.
Failure to follow these instructions may result in possible serious or fatal injury.

NOTE:
- a 12 Volt battery charger with a minimum 30 Amp rating is the only type recommended to use when charging the high voltage battery.
- depending on the condition of the second running vehicles alternator and the number of accessories operating on both vehicles, it could take up to 60 minutes to charge the high voltage battery. To minimize the charging time make sure that the minimum amount of accessories are being used.

WARNING: Always wear eye protection and remove all metal jewelry such as watch bands or bracelets which might make an unintended electrical contact. Failure to follow these instructions may result in possible serious or fatal injury.

1. Turn off all unnecessary electrical loads such as the heater, radio, lights etc.
2. Set the parking brake, place the transmission in PARK and turn the ignition to the ON/RUN position.
3. Place the battery charger within cable reach of the remote battery posts located under the hood.




4. Connect the positive cable clamp of the 12 Volt battery charger to the remote positive post located near the engine oil dipstick underhood.





5. Connect the negative cable clamp of the 12 Volt battery charger to the remote negative post located near the driver side fender underhood.

WARNING: During cold weather when temperatures are below freezing point, electrolyte in a discharged battery may freeze. Do not attempt jump-starting because the battery could rupture or explode. The battery temperature must be brought up above freezing point before attempting a jump-start. Failure to follow these instructions may result in possible serious or fatal injury.

6. Place the 12 Volt battery charger to a medium setting and turn ON the battery charger to allow the high voltage battery to charge.






CAUTION: Using a setting higher then a medium rate of charge could damage the 12 Volt battery.

7. If the 12 Volt battery charger has been properly connected and the system determines that the conditions are correct for charging, the navigation radio displays a message "CHARGING in Progress".

NOTE: To minimize the charging time, it is recommended to leave the key in the OFF position while in the "CHARGING in Progress" mode, however the key may be turned to the ON/RUN position to use an accessory.






Allow the system to charge until the navigation radio displays the "Attempt to start vehicle" message.

8. Attempt to start the vehicle, if the vehicle starts, leave it running and turn off the 12 Volt battery charger.
9. Remove the 12 Volt battery charger negative clamp.

CAUTION: Be careful of the moving belt and fan blades.

10. Remove the 12 Volt battery charger positive clamp.

WARNING: Any procedure other than above could result in:
- personal injury caused by electrolyte squirting out the battery vent.
- personal injury or property damage due to battery explosion.
- damage to charging system or immobilized vehicle.
Failure to follow these instructions may result in possible serious or fatal injury.

Charging Aborted





If the "Jump Assist" procedure is interrupted, the navigation radio displays "Charge Aborted".

"Jump Assist" can be aborted by the following items:

- the key is turned to the START position while the system is being charged.
- incorrect installation of the 12 Volt battery charger.
- poor cable clamp contact.
- the Hybrid Control Module determines conditions are not suitable for charging.

If the "Charge Aborted" message is displayed check the battery charger clamps, make sure there is a good connection. Check to see that the 12 Volt battery charger is turned on. Turn off the ignition, wait 10 to 15 seconds and turn the key to the START position. If the "Charge Aborted" message is still active have the vehicle towed to the nearest authorized dealer for service.

If acid splashes in eyes or on skin, flush the contaminated area immediately with large quantities of water.
- a battery generates hydrogen gas which is flammable and explosive. Keep flame or spark away from the vent holes. Do not use a booster battery or any other booster source with an output that exceeds 12 Volts.
Failure to follow these instructions may result in possible serious or fatal injury.

Check the Battery Test Indicator (if equipped). If a light or bright colored dot is visible in the indicator (if equipped), Do Not jump-start the battery.

If the indicator (if equipped) is dark or shows a green dot, proceed as follows:

1. Wear eye protection and remove all metal jewelry such as watch bands or bracelets which might make an unintended electrical contact.
2. Park the booster vehicle within cable reach but without letting the vehicles touch. Set the parking brake, place the automatic transmission in PARK and turn the ignition off on both vehicles.
3. Turn off heater, radio and all unnecessary electrical loads.
4. Connect one end of a jumper cable (4) to the positive terminal (5) of the booster battery.





5. Connect the other end of the same cable to the remote positive post.
WARNING: Do not permit vehicles to touch each other as this could establish a ground connection and personal injury could result. Failure to follow these instructions may result in possible serious or fatal injury.





6. Connect the other cable, first to the negative terminal of the booster battery then to the engine of the vehicle with the discharged battery. Make sure you have a good contact on the engine.

WARNING: Do not connect the cable to the negative post of the discharge battery. The resulting electrical spark could cause the battery to explode.
During cold weather when temperatures are below freezing point, electrolyte in a discharged battery may freeze. Do not attempt jump-starting because the battery could rupture or explode. The battery temperature must be brought up above freezing point before attempting a jump-start. Failure to follow these instructions may result in possible serious or fatal injury.

7. Start the engine in the vehicle which has the booster battery, let the engine idle a few minutes, then start the engine in the vehicle with the discharged battery.
