APPLICABILITY:
INTRODUCTION:
The CT200h is equipped with 2 types of special batteries:
- Hybrid Vehicle (HV) battery
- 12-volt auxiliary battery.
If the CT200h is put into storage, the state of charge (SOC) of its HV battery and auxiliary battery will gradually decrease. To prevent the battery from becoming discharged during storage, proper maintenance is necessary.
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 switch is selected to the "START" mode, the hybrid system may NOT start. In this case, push the POWER switch to select "START" 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.

REQUIRED SSTs:
BEFORE DELIVERY:
Fully charge the 12-volt auxiliary battery:
1. Before charging the auxiliary battery, turn OFF all lights and accessories.
2. Open the rear door and remove the center and right side auxiliary boxes.
3. Open the battery cover.
4. Remove the positive (+) terminal cover.
5. Check the battery SOC.
- If the battery voltage is LESS THAN 12.6 V, then continue to step 5.
- If the battery voltage is 12.6 V or MORE, replace the positive (+) terminal, close the battery cover, install the luggage compartment floor mat, and close the trunk.
CAUTION
If measuring the voltage with the negative (-) terminal connected, verify IG/OFF, and turn headlights on for 60 seconds or more. This removes the surface charge.
6. Charge the 12-volt auxiliary battery.
A. Connect the red charger clamp to the positive (+) battery terminal and the black charger clamp to the negative (-) battery terminal.
B. Plug the charger into a grounded 110-volt outlet and flip the power switch to the "ON" position.
C. Once the charger is properly turned ON, perform a diagnostic charge by "MODEL" (CT200h). The GR8 Battery Diagnostic Station will indicate result when complete.
NOTE
- If the CT200h is not listed in the model list, charge by battery stock code. To charge by Stock Code, reference the Battery Stock Code Chart located on the "Battery" on ETAS.
- If the auxiliary battery was stored at 0°C (32°F) or below, charge the auxiliary battery in a room above 0°C (32°F).
CAUTION
- Charge in a well-ventilated area.
- Do NOT allow sparks or fire near the auxiliary battery.
7. If the GR8 Battery Diagnostic Station is NOT available, you may charge the 12-volt battery by turning the vehicle to "Ready-On."
- 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.
8. After charging the auxiliary battery, install the positive (+) terminal cover.
9. Close the battery cover and install the center and right side auxiliary boxes.
10. Close the rear door.
TO STORE FOR 30 DAYS OR MORE:
Disconnect the negative (-) terminal:
1. Turn OFF all lights and accessories.
2. Open the trunk.
3. Remove the luggage compartment floor mat and open the battery cover.
4. Disconnect the negative (-) terminal.
5. Close the battery cover and install the center and right side auxiliary boxes.
6. Close the rear door.
NOTE
When it is necessary to move the vehicle, reconnect the negative (-) terminal.
Connect the negative (-) terminal:
1. Open the rear door.
2. Remove the center and right side auxiliary boxes and open the battery cover.
3. Connect the negative (-) terminal.
Torque: 6.0 N-m (61 kgf-cm, 4.4 ft-lbf)
4. Close the battery cover and install the center and right side auxiliary boxes.
5. Close the rear door.
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. 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 switch and check that the "READY" light in the meter illuminates when the hybrid system starts (the "READY" light is ON).
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.
