ADDITIONAL INFORMATION
REVISION NOTICE
August 31, 2015 Rev1:
• Applicability has been updated to include 2016 model year Avalon HV, Camry HV, RAV4 HV,
and Highlander HV vehicles.
Any previous printed versions of this bulletin should be discarded.
Introduction
Hybrid vehicles are equipped with 2 types of batteries:
• Hybrid Vehicle (HV) battery
• 12-volt auxiliary battery
If the hybrid vehicle is put into storage, the state of charge (SOC) of its HV battery and auxiliary
battery will gradually decrease. To prevent the auxiliary battery from becoming discharged during
storage, proper maintenance is necessary.
Please perform the following maintenance service for the HV battery and 12-volt auxiliary battery.
NOTE
• Before disconnecting the auxiliary battery, confirm the shift lever is in the “P” position and
apply the parking brake completely. The shift lever CANNOT be shifted from the “P” position
with the 12-volt auxiliary battery disconnected.
• If the negative (–) terminal of the auxiliary battery is reconnected, even if the power button is in
the “START” mode, the hybrid system may NOT start. In this case, push the “POWER” button
and select the “START” mode again to start the hybrid system (the “READY” light is ON). If the
hybrid system still does NOT start (the “READY” light is OFF), refer to the Repair Manual.

MAINTENANCE OPERATION
Before Delivery
Fully charge 12-volt auxiliary battery (deliver the vehicle to
the customer after it is fully charged 12.6 V or more).
To Store for 30 Days or More
Disconnect the negative (–) terminal of the 12-volt
auxiliary battery in the luggage compartment to prevent
the SOC of the auxiliary battery from decreasing during
storage due to parasitic current.
Just After Unloading & Every 2 Months
Keep the Hybrid System ON for 30 minutes with the
transmission in the “P” position (in order to charge the
HV battery and the auxiliary battery).
* The condition also corresponds with the section titles within this bulletin.

Maintenance for HV & Auxiliary Batteries
Before Delivery
Fully charge the 12-volt auxiliary battery:
1. Before charging the auxiliary battery, turn OFF all lights, accessories, and the hybrid system.
2. Check the battery SOC.
• If the battery voltage is LESS THAN 12.6 V, then continue to step 3.
• If the battery voltage is 12.6 V or MORE, replace the positive (+) terminal cover, install
battery cover and close the back door.
NOTE
• If measuring the voltage with the negative (–) terminal connected, turn OFF the power
switch and turn ON the headlights for 20 to 30 seconds. This will remove the surface
charge from the battery.
• If the engine has been running before measuring the voltage, wait 20 minutes or more after
the engine stops. This removes the surface charge.
3. Test the 12-volt auxiliary battery using the
Diagnostic Charge Mode on the GR8 Battery.
Figure 1. GR8 Battery Diagnostic Station.

• If the battery tests good, the GR8 will prepare
to charge the battery .
• If the battery tests bad (“Replace Battery”),
then replace the auxiliary battery.
CAUTION
• Charge in a well-ventilated area.
• Do NOT allow sparks or fire near the
auxiliary battery.

P/N 00002-MCGR8
NOTE
If the auxiliary battery was stored at 32◦F (0◦C) or below, charge the auxiliary battery in a room
above 32◦F (0◦C).
If the GR8 Battery Diagnostic Station is NOT available, you may charge the 12-volt battery by
cycling the vehicle on to “READY.”
• Run time will vary depending on the state of charge.
• If this method is used, you must confirm that the battery is charged to 12.8 volts using a DVOM.

Maintenance for HV & Auxiliary Batteries
To Store for 30 Days or More
Disconnect the negative (–) terminal:
1. Turn OFF all lights, accessories, and the hybrid system.
2. Disconnect the negative (–) terminal.
NOTE
When it is necessary to move the vehicle, reconnect the negative (–) terminal.
When removing the vehicle from storage, connect the negative (–) terminal:
1. Connect the negative (–) terminal.

After recharging the auxiliary battery, the
hybrid system may NOT start. Follow the
procedure below to initialize the system.
• Put the shift lever in the “P” position.
• Open and close any of the doors.
• Restart the hybrid system.

Maintenance for HV & Auxiliary Batteries
Every Two Months
Cycle vehicle to “READY” ON:
NOTE
• When the remaining capacity of the HV battery is low, the gasoline engine automatically starts
and the HV battery is charged by the generator. The 12-volt auxiliary battery is also charged by
the HV battery regardless of the gasoline engine operation.
• Be sure to reconnect the negative (–) terminal of the auxiliary battery BEFORE performing
this procedure.
1. Park the vehicle in open air or connect the exhaust extraction hose to the exhaust pipe.
2. Apply the parking brake.
3. With the brake pedal depressed, push the
“POWER” button and select the “START” mode
and check that the “READY” light in the meter
illuminates when the hybrid system starts (the
“READY” light is ON).
Figure 3..
4. Turn OFF all lights and accessories.
5. Check that the shift lever is in the “P” position.
6. Keep the “READY” light on and charge the HV battery for 30 minutes.
NOTE
• If the amount of charging energy is small, the display may NOT indicate the energy flow.
• Ensure there is a sufficient amount of fuel for the vehicle to run for 30 minutes.
