   4. Pressing the engine switch without depressing the brake pedal turns the power source mode from on (IG) to off.

3. Starting the engine when the electrical key transmitter sub-assembly does not operate correctly due to wave interference or transmitter battery depletion:

   
   

   1. Unlock the door using the built-in mechanical key and get into the vehicle while carrying the electrical key transmitter sub-assembly.

   2. While depressing the brake pedal with the shift lever in P and facing the logo side of the electrical key transmitter sub-assembly towards the engine switch, hold the electrical key transmitter sub-assembly near the engine switch.

   4. Press the engine switch with the brake pedal depressed to start the engine.

CHECK PUSH-BUTTON START FUNCTION

1. Check the push-button start function:

   
   
   1. 

      *A	for F SPORT Models (Movable meter ring not activated)
      *B	for F SPORT Models (Movable meter ring activated)
      *C	except F SPORT Models
      *a	Key Indicator Display

      Get into the vehicle while carrying the electrical key transmitter sub-assembly with the engine switch off. With the shift lever in P, check that the key indicator is displayed when the brake pedal is depressed. Check that the engine starts when the engine switch is pressed after the key indicator is displayed on the multi-information display.

   2. While the brake pedal is released and the electrical key transmitter sub-assembly is being carried, check that the power source mode changes in the following order when the engine switch is pressed: off → on (ACC) → on (IG) → off.

      Tech Tips

      When the engine switch is pressed with the engine switch on (IG) and the shift lever not in P, the power source mode does not change to off, but changes to on (ACC).

   3. With the shift lever in P, check that the steering lock operates when a door is opened.

      Tech Tips

      When the engine switch is pressed after the vehicle is stopped, the engine stops and all the power turns off. However, if the shift lever is not in P when the engine switch is pressed with the vehicle stopped, the power source mode does not change to off, but changes to on (ACC).

   4. 

      *a	Inspection Point

      Check the push-button start function operation range for the front side. Place the electrical key transmitter sub-assembly at either inspection point so that it is facing the direction shown in the illustration, and then check that the engine can be started.

      Note

      Even if the electrical key transmitter sub-assembly is in a vehicle interior key detection area, the electrical key transmitter sub-assembly may not be properly detected if the electrical key transmitter sub-assembly is on the instrument panel, in the glove box or on the floor.

      Tech Tips

      
      

      • Communication may not be possible if the electrical key transmitter sub-assembly is within 0.2 m (0.656 ft.) of the shift lever.

      • Perform this inspection for both inspection points.

   5. 

      *a	Inspection Point

      Check the push-button start function operation range for the rear side. Place the electrical key transmitter sub-assembly at either inspection point so that it is facing the direction shown in the illustration, and then check that the engine can be started.

      Note

      Even if the electrical key transmitter sub-assembly is in a vehicle interior key detection area, the electrical key transmitter sub-assembly may not be properly detected if the electrical key transmitter sub-assembly is on the instrument panel, in the glove box or on the floor.

      Tech Tips

      
      

      • Communication may not be possible if the electrical key transmitter sub-assembly is within 0.2 m (0.656 ft.) of the center of the rear seat.

      • Perform this inspection for both inspection points.

2. Check the key lock-in prevention function (in luggage compartment):

   
   

   1. Place the electrical key transmitter sub-assembly in the luggage compartment with all doors locked. Check that: 1) closing the luggage compartment door triggers the wireless buzzer (which lasts approximately 2 seconds), and 2) pressing the luggage electrical key switch opens the luggage compartment door.

   2. 

      *a	Inspection Point

      Inspect the key lock-in prevention detection area. Pay attention to the direction of the electrical key transmitter sub-assembly shown in the illustration. When the electrical key transmitter sub-assembly is in either of the 2 locations in the illustration, check that: 1) closing the luggage compartment door sounds the wireless buzzer, and 2) pressing the luggage electrical key switch opens the luggage compartment door.

      Note

      In order to prevent the electrical key transmitter sub-assembly from being locked inside the vehicle, perform this inspection with the window of a door open.

      If the electrical key transmitter sub-assembly is in any of the following locations, the key lock-in prevention function may not operate:

      
      

      • Near the spare tire or at the edge of the luggage compartment.

      • In a metal bag or near a metal object.

   3. 

      *a	0.1 m or more (0.328 ft. or more)

      Inspect the key lock-in prevention detection area and the door control receiver for wave leaks. Hold the electrical key transmitter sub-assembly at the same height as the lower edge of the luggage compartment door aligning it with the center of the rear of the vehicle. Pay attention to the direction and position of the electrical key transmitter sub-assembly shown in the illustration.

      Tech Tips

      
      

      • When the electrical key transmitter sub-assembly is over 0.1 m (0.328 ft.) from the rear bumper, the wireless buzzer does not sound.

      • If the wireless buzzer sounds, the No. 1 indoor electrical key antenna assembly (inside luggage) may have a wave leak.

3. Check the key lock-in prevention function (vehicle interior).

   Note

   In order to prevent the electrical key transmitter sub-assembly from being locked inside the vehicle, perform this inspection with the window of a door open.

   
   

   1. Turn the engine switch off.

   2. Place the electrical key transmitter sub-assembly on a front or rear seat.

   3. Close the door, making sure the doors are unlocked.

   4. Touch a door lock sensor and check that the doors do not lock and the key lock-in prevention function buzzer (external) sounds for approximately 5 seconds.

KEY DIAGNOSTIC MODE (Using GTS)

CHECK TRANSMITTER BATTERY SAVING MODE FUNCTION

1. Check the transmitter battery saving mode function:

   
   

   1. Press the unlock switch of the electrical key transmitter sub-assembly twice while pressing the lock switch and check that the electrical key transmitter sub-assembly LED blinks 4 times and enters transmitter battery saving mode.

   2. Check that the push-button start does not operate while in transmitter battery saving mode.

      Tech Tips

      To cancel transmitter battery saving mode, press a switch of the electrical key transmitter sub-assembly.

CHECK POWER SOURCE MODE CHANGING FUNCTION

1. Check the engine switch.

   
   

   1. Check that the power source mode changes according to the chart below.

      Shift Position	Brake Pedal	Power Source Mode when Engine Switch Pressed
      P	Released	Off → on (ACC) → on (IG) → off
      P	Released	Engine running → off
      P	Released	On (ACC)* → off
      P	Depressed	Off → engine starts
      P	Depressed	On (ACC) → engine starts
      P	Depressed	On (IG) → engine starts
      P	Depressed	Engine running → off
      P	Depressed	On (ACC)* → off
      N	Released	Off → on (ACC) → on (IG) (after power source mode changes to on (IG), power source mode changes between on (IG) and on (ACC) every time engine switch is pressed)
      N	Released	Engine running → on (ACC)
      N	Depressed	Off → engine starts
      N	Depressed	On (ACC) → engine starts
      N	Depressed	On (IG) → engine starts
      N	Depressed	Engine running → on (ACC)
      Not P or N	Released	Off → on (ACC) → on (IG) (after power source mode changes to on (IG), power source mode changes between on (IG) and on (ACC) every time engine switch is pressed)
      Not P or N	Released	Engine running → on (ACC)
      Not P or N	Depressed	Off → on (IG)
      Not P or N	Depressed	On (ACC) → on (IG)
      Not P or N	Depressed	Engine running → on (ACC)

      Tech Tips

      *: This situation is only applicable when the power source mode has changed from on (IG) to on (ACC). (Excluding an emergency stop by pressing the engine switch 3 times quickly or pressing and holding the engine switch for 2 seconds or more.)
