PRECAUTION FOR REPLACING COMBINATION METER ASSEMBLY

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

PRECAUTION FOR REFUELING

(a) Refueling Judgment Conditions

NOTICE:

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.

  • With the ignition switch off, the fuel sender gauge assembly and No. 2 fuel sender gauge assembly detects a change of 6.0 liters (6.3 US qts, 5.3 Imp. qts) or more in the fuel level.
  • With the ignition switch ON and the vehicle and engine stopped, the fuel sender gauge assembly and No. 2 fuel sender gauge assembly detects a change of 6.0 liters (6.3 US qts, 5.3 Imp. qts) or more in the fuel level.

(b) Precaution for Fuel Receiver Gauge

  • The fuel sender gauge assembly and No. 2 fuel sender gauge assembly cannot detect changes in the fuel level within certain ranges (around points E, 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.

(c) Forced Reset of Fuel Receiver Gauge

  • When refueling judgment conditions are not met, if the output of the fuel sender gauge assembly, No. 2 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.

(d) 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
