PRECAUTIONS FOR HIGH-VOLTAGE CIRCUIT INSPECTION AND SERVICE
CAUTION:
This vehicle has a hybrid system that operates at voltages up to 650 V. The hybrid system uses an EV battery that contains an electrolyte which is a strong alkali solution that includes potassium hydroxide. Be sure to follow the instructions in this manual to handle the system correctly. Failure to do so may result in serious injury or electrocution.
Technicians must undergo special training to be able to service and inspect the high-voltage system.
All high-voltage wire harnesses and connectors are colored orange. The EV battery and other high-voltage components have "High Voltage" caution labels. Do not carelessly touch these wires or components.
When there is a problem with the wire harness or connector of a high-voltage circuit, repairs to the harness or connector should not be attempted. Replace damaged or malfunctioning high voltage cables or connectors.
Before performing any of the following operations, be sure to follow all safety measures, such as turning the power switch off, wearing insulated gloves, and removing the service plug grips from both the FC stack and EV battery to prevent electrocution.
Working on the high-voltage system
Disconnecting the low voltage connector of the inverter with converter assembly
Disconnecting the low voltage connector of the EV battery
Disconnecting the low voltage connector of the FC stack assembly
Disconnecting the low voltage connector of the FC converter assembly
After removing the service plug grips from the FC stack and EV battery, store them according to the following guidelines to prevent other technicians from accidentally reconncting them while you are working on the high-voltage systems.
Carry the service plug grip removed from the EV battery in your pocket to prevent other technicians from accidentally reconnecting it while you are servicing the vehicle.
Store the service plug grip removed from the FC stack in a safe location and use the "CATION: HIGH VOLTAGE DO NOT TOUCH" sign to notify other technicians that you are working on the hign-voltage system.
Note
After turning the power switch off, waiting time may be required before disconnecting the cable from the negative (-) auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) auxiliary battery terminal notices before proceeding with work.
After removing the service plug grip, turning the power switch on (READY) may cause a malfunction. Do not turn the power switch on (READY) unless instructed by the repair manual.
Tech Tips
Remove the service plug grips from both the FC stack and EV battery, in no particular order.
Before using insulated gloves, be sure to check them for cracks, tears and other types of damage by performing the following procedure.
Place the glove on its side.
Roll the opening up 2 or 3 times.
Fold the opening in half to close it.
Confirm that there are no air leaks.
When servicing the vehicle, do not carry metal objects like mechanical pencils or rulers that can be dropped accidentally and cause a short circuit.
Before touching a bare high-voltage terminal, wear insulated gloves and use a tester to make sure that the terminal voltage is 0 V.
After disconnecting or exposing a high-voltage connector or terminal, insulate it immediately using insulating tape.
Bolts and nuts for high-voltage terminals should be tightened firmly to the specified torque. Both insufficient and excessive torque can cause failure.
Use the "CAUTION: HIGH VOLTAGE DO NOT TOUCH" sign to notify other technicians that the high-voltage system is being inspected and/or repaired.

ACTIONS TO BE TAKEN WHEN BATTERIES ARE DISCHARGED
Tech Tips
The vehicle uses a 12 V auxiliary and a 244.8 V EV battery. Therefore, there are 2 recharging methods when the batteries are discharged.
Perform this procedure when the auxiliary battery is fully discharged.
Tech Tips
The following problems indicate that the auxiliary battery is discharged:
No display appears on the instrument panel when the power switch is turned on (IG).
The FC control system does not start.
The headlights are dim.
The sound from the horn is weak.
Note
Never use a quick charger.
The booster terminal cannot be used to rescue a vehicle with a discharged battery.
Engage the parking brake.
Turn the power switch off and remove the key from the interior detection area.
Remove the No. 1 relay block cover.
Disengage the claw and open the cover of the booster terminal.
Place Hands Here | |
Remove in this Direction |
Disengage the grommets and remove the inverter cover.
Using booster cables, connect the 12 V auxiliary battery of the rescue vehicle and the auxiliary battery of the stalled vehicle as shown in the illustration.
Tech Tips
Use the booster terminal in the motor compartment.
*1 | Booster Terminal | *2 | Auxiliary Battery of Rescue Vehicle |
Connecting Sequence | Connecting Location |
---|---|
1 | Positive booster terminal of stalled vehicle |
2 | Positive auxiliary battery terminal of rescue vehicle |
3 | Negative auxiliary battery terminal of rescue vehicle |

Start the engine of the rescue vehicle and run the engine at a speed slightly higher than usual.
Turn the power switch on (READY).
Note
Immediately disconnect the booster cables in the reverse order of connection after the hybrid system has started. Do not leave the booster cables connected because they are not designed for recharging purposes.
If the hybrid system fails to start and the EV battery warning message is displayed on the multi-information display, the EV battery may be discharged.
When the EV battery is discharged:
Replace the EV battery.
Tech Tips
Perform this operation when the EV battery is discharged or low, or if a low traction battery warning message is displayed on the multi-information display and DTC P0AF8-816, P3000-388 or 389 is stored in the EV control ECU.
ACTIONS TO BE TAKEN FOR VEHICLES DAMAGED BY IMPACT (Hydrogen System)
CAUTION:
Hydrogen gas is a colorless, odorless and flammable gas.
Because the flammable concentration range is wide (4 - 74.5%) and the energy required for ignition is extremely low, even static electricity can easily cause hydrogen gas to ignite. While working on the vehicle, if the sound of hydrogen gas leaking (a loud hissing sound) can be heard, measure the hydrogen gas concentration with a hydrogen concentration detector. If the hydrogen gas concentration near the vehicle is more than 4%, there is a danger that the hydrogen could ignite, so move away from the vehicle immediately.
Even after the vehicle is stopped, there is still hydrogen gas remaining in hydrogen equipment such as the hydrogen tanks and in the hydrogen piping. To avoid fires or explosions, do not cut or destroy hydrogen equipment or hydrogen piping.
Because of the danger of hydrogen igniting, when a hydrogen leak is present, do not use electrical devices or rescue devices that could generate static electricity.

*3 | No. 2 Hydrogen Tank Assembly | *4 | Hydrogen Supply Regulator Assembly |
*5 | Hydrogen Tube Joint (Inlet Side) | *6 | Hydrogen Tube Joint (Outlet Side) |
In case of a vehicle fire
A fuel cell vehicle (FCV) contains compressed hydrogen gas.
When spraying water on the fire, prepare for the hydrogen to ignite, and keep your distance from the vehicle while spraying water.
In particular, spray a large amount of water on the hydrogen tanks under the floor at the rear of the vehicle to keep them cool.
If the hydrogen has ignited, completely extinguishing the fire could cause unburned hydrogen gas to collect, which could result in a secondary explosion. To prevent this, spray water to keep the fire from spreading to the surroundings, and wait for the fire to burn itself out (when all the fuel has been expended).
To prevent the hydrogen tanks from exploding due to abnormal temperature / pressure increase, pressure relief device designed into the hydrogen tanks will open when the temperature exceeds 110°C, causing the hydrogen gas inside the tanks to be discharged toward the rear of the vehicle.
Although pure hydrogen gas burns with a nearly colorless flame that is very difficult to see, in the case of a vehicle fire, the flames will be mixed with other flames from nearby combustible materials, making them easier to see.
A peculiar characteristic of hydrogen flame is that while the temperature of the flame itself is extremely high, because the flame emits very little radiant heat, it is difficult to feel the heat of the fire when approaching it.
Make sure that the sound of hydrogen gas leaking (a loud hissing sound) cannot be heard.
When approaching the vehicle, approach from the front side of the vehicle.
When a leaking sound can be heard, there is a danger of igniting the hydrogen, so move away from the vehicle immediately.
Check that the leaking sound has stopped before moving on to the following procedure.
Using a hydrogen concentration detector, measure the hydrogen concentration around the vehicle to make sure that it does not exceed 4%.
If the concentration exceeds 4%, there is a danger of igniting the hydrogen, so move away from the vehicle immediately.
If a fan or blower is available, blow air to reduce the hydrogen concentration. When approaching the vehicle, approach from the upwind side.
Periodically measure the hydrogen concentration, and make sure that the hydrogen concentration does not exceed 4% before moving on to the following procedure.

FOR VEHICLES EQUIPPED WITH SRS AIRBAG AND SEAT BELT PRETENSIONER
This vehicle is equipped with a Supplemental Restraint System (SRS).
CAUTION:
Before performing pre-disposal deployment of any SRS component, review and closely follow all applicable environmental and hazardous material regulations. Pre-disposal deployment may be considered hazardous material treatment.
Failure to carry out the service operations in the correct sequence could cause the SRS to unexpectedly deploy during servicing and lead to a serious injury. Furthermore, if a mistake is made when servicing the SRS, it is possible that the SRS may fail to operate properly. Before servicing (including removal or installation of parts, inspection or replacement), be sure to read the following section carefully.
GENERAL NOTICE
As malfunctions of the SRS are difficult to confirm, Diagnostic Trouble Codes (DTCs) become the most important source of information when troubleshooting. When troubleshooting the SRS, always check for DTCs before disconnecting the auxiliary battery.
Work must be started at least 90 seconds after the power switch is turned off and the cable is disconnected from the negative (-) auxiliary battery terminal.
The SRS is equipped with a back-up power source. If work is started within 90 seconds of turning the power switch off and disconnecting the cable from the negative (-) auxiliary battery terminal, the SRS may deploy.
When the cable is disconnected from the negative (-) auxiliary battery terminal, the clock and audio system memory will be cleared. Before starting work, make a note of the settings of each memory system. When work is finished, reset the clock and audio system as before.
CAUTION:
Never use a back-up power source (auxiliary battery or others) to avoid clearing the system memory. The back-up power source may inadvertently power the SRS and cause it to deploy.
If the vehicle has been involved in a minor collision where the SRS does not deploy, the steering pad, front passenger airbag assembly, knee airbag assembly, seat side airbag assemblies, SRS seat cushion airbag assembly, curtain shield airbag assemblies and seat outer belt assemblies should be inspected before further use of the vehicle.
