Precaution [09/2022 - 11/2022]

HINT: 

When disconnecting and reconnecting the auxiliary battery, there is an automatic learning function that completes learning when the respective system is used.

Refer to BEFORE DISCONNECTING BATTERY [09/2022 - ]

• When replacing the combination meter assembly, always replace it with a new one. If a combination meter assembly which was installed to another vehicle is used, the information stored in it will not match the information from the vehicle and a DTC may be stored.
• for TMC Made

  When replacing the combination meter assembly, update the ECU security key.

  Refer to UPDATE ECU SECURITY KEY [09/2022 - ]

1. Refueling Judgment Conditions
   NOTE:

   Add fuel with the ignition switch off to ensure safety and to enable refueling judgment so that an appropriate fuel receiver gauge reading will be obtained.

   for HV Model 

   • With the ignition switch off, the fuel sender gauge assembly detects a change of 2.0 liters (2.1 US qts, 1.8 Imp. qts) or more in the fuel level.
   • With the ignition switch ON (IG) or ON (READY) and the vehicle and engine stopped, the fuel sender gauge assembly detects a change of 2.0 liters (2.1 US qts, 1.8 Imp. qts) or more in the fuel level.

   for Gasoline Model 

   • With the ignition switch off, the fuel sender gauge assembly detects a change of 5.0 liters (5.3 US qts, 4.4 Imp. qts) or more in the fuel level.
   • With the ignition switch ON and the vehicle and engine stopped, the fuel sender gauge assembly detects a change of 5.0 liters (5.3 US qts, 4.4 Imp. qts) or more in the fuel level.
2. Precaution for Fuel Receiver Gauge

   for HV Model 

   • The fuel sender gauge assembly cannot detect changes in the fuel level within certain ranges (around points E and F). Therefore, even if the refueling judgment conditions are satisfied, the fuel receiver gauge reading may not change when the fuel level is within either range.
   • When refueling judgment is performed, it takes up to approximately 25 seconds for the fuel receiver gauge reading to change to the appropriate level.
   • If the cable is disconnected from the negative (-) auxiliary battery terminal, the pressure inside the fuel tank will change. After the cable is reconnected to the negative (-) auxiliary battery terminal, it takes approximately 15 seconds for the pressure inside the fuel tank to be restored. During this time, the indicated value of the fuel receiver gauge may change.

   for Gasoline Model 

   • The fuel sender gauge assembly cannot detect changes in the fuel level within certain ranges (around points E and F). Therefore, even if the refueling judgment conditions are satisfied, the fuel receiver gauge reading may not change when the fuel level is within either range.
   • When refueling judgment is performed, it takes up to approximately 25 seconds for the fuel receiver gauge reading to change to the appropriate level.
3. Forced Reset of Fuel Receiver Gauge

   for HV Model 

   1. When refueling judgment conditions are not met, if the output of the fuel sender gauge assembly and the fuel receiver gauge reading differ by 15.0 liters (15.9 US qts, 13.2 Imp. qts) or more for approximately 5 minutes continuously, the fuel receiver gauge reading will reflect the detected fuel level without correction and it may take up to approximately 25 seconds for the reading to change to the appropriate level.

   for Gasoline Model 

   1. When refueling judgment conditions are not met, if the output of the fuel sender gauge assembly and the fuel receiver gauge reading differ by 15.0 liters (15.9 US qts, 13.2 Imp. qts) or more for approximately 5 minutes continuously, the fuel receiver gauge reading will reflect the detected fuel level without correction and it may take up to approximately 25 seconds for the reading to change to the appropriate level.
4. Fuel Receiver Gauge Manual Update
   1. Stop the vehicle on a flat surface.
   2. Display the odometer on the multi-information display.
   3. Turn the ignition switch off.
   4. With the ODO/TRIP switch pressed, perform the following procedures.
      1. Turn the ignition switch to ON.
      2. Continue to keep the ODO/TRIP switch pressed for 5 seconds until the odometer blinks.
      3. After the odometer blinks, release the ODO/TRIP switch.

      HINT: 

      By performing the fuel level data update, the following items are updated or reset.

      • Fuel receiver gauge indicator updated
      • Driving range updated
      • Average fuel consumption (after refuel) reset
