CHECK THE ENTRY UNLOCK FUNCTION
(a) Check the entry unlock function (driver door, front passenger door).
(1) Perform a wireless lock door operation to lock the door, touch the unlock sensor built into the backside of the front door outside handle assembly of the driver door while carrying the electrical key transmitter sub-assembly and check that the door unlocks.
(2) Inspect the entry unlock detection area. Hold the electrical key transmitter sub-assembly at the same height as the door outside handle assembly and approximately 0.7 to 1 m (2.30 to 3.28 ft.) from the vehicle as shown in the illustration and check that the LED (red) of the electrical key transmitter sub-assembly blinks.
(3) With the system in unlock standby mode, grasp the front door outside handle assembly LH and check that the door unlocks.
| *a | 0.7 to 1 m (2.30 to 3.28 ft.) |
HINT:
- The system is in unlock standby mode when the electrical key transmitter sub-assembly is in the detection area and the key ID code sent by the electrical key transmitter sub-assembly matches the key ID code stored by the certification ECU (smart key ECU assembly).
- Communication may not be possible if the electrical key transmitter sub-assembly is within 0.2 m (0.656 ft.) of the door outside handle assembly.
- Inspect the front passenger door using the same procedure.
(4) Check the unlock response sensitivity. With the system in unlock standby mode, touch the area shown in the illustration and check that the door unlocks.
NOTICE:
If the sensor is touched too quickly or released too slowly, the sensor may not react and the door will not unlock.
HINT:
Inspect the front passenger door using the same procedure.
| *a | Unlock Sensor (Backside) |
CHECK THE ENTRY LOCK FUNCTION
| *a | Lock Sensor |
(a) Check the entry lock function (driver door, front passenger door).
NOTICE:
If the electrical key transmitter sub-assembly is in the vehicle but outside the detection area (on the instrument panel, in the glove box, on the floor) and a door lock operation is performed, the key lock-in prevention function will not operate and the electrical key transmitter sub-assembly will be locked inside the vehicle.
(1) With the door closed and unlocked, touch the lock sensor of the front door outside handle assembly of the driver door while carrying the electrical key transmitter sub-assembly and check that the door locks.
HINT:
- If the door does not lock even when touching the lock sensor, touch it with your palm.
- Inspect the front passenger door using the same procedure.
(2) Inspect the entry lock operating range. Hold the electrical key transmitter sub-assembly approximately 0.7 to 1 m (2.30 to 3.28 ft.) below the bottom edge of the door glass and approximately 0.3 m (0.984 ft.) from the vehicle as shown in the illustration, touch the lock sensor and check that the door locks.
HINT:
- If the door does not lock even when touching the lock sensor, touch it with your palm.
- As communication may not be possible if the electrical key transmitter sub-assembly is within 0.2 m (0.656 ft.) of the front door outside handle assembly, the door may not lock if the lock sensor is touched with the same hand that is carrying the electrical key transmitter sub-assembly, etc.
- If the key lock-in prevention function buzzer sounds, radio waves from the indoor electrical key antenna may be leaking from the vehicle.
- Inspect the front passenger door using the same procedure.
- The entry lock function cannot be operated more than 3 times consecutively.
| *a | 0.3 m (0.984 ft.) |
CHECK ENTRY BACK DOOR OPEN FUNCTION
(a) Check the entry back door open function.
(1) With the back door closed and locked, press the lock switch of the back door opener switch assembly while carrying the electrical key transmitter sub-assembly and check that the back door opens.
| *1 | Back Door Opener Switch Assembly (Open Switch) |
| *a | 0.7 to 1 m (2.30 to 3.28 ft.) |
(2) Inspect the entry back door open operating range. Hold the electrical key transmitter sub-assembly at the same height as the rear bumper upper surface and approximately 0.7 to 1 m (2.30 to 3.28 ft.) from the vehicle as shown in the illustration, press the open switch of the back door opener switch assembly and check that the back door opens.
HINT:
Communication may not be possible if the electrical key transmitter sub-assembly is within 0.2 m (0.656 ft.) of rear bumper.
CHECK ENTRY BACK DOOR LOCK FUNCTION
(a) Check the entry back door lock function.
NOTICE:
If the electrical key transmitter sub-assembly is in the vehicle but outside the detection area (on the instrument panel, in the glove box or on the floor) and a back door lock operation is performed, the key lock-in prevention function will not operate and the electrical key transmitter sub-assembly will be locked inside the vehicle.
(1) With the back door closed and unlocked, press the lock switch of the back door opener switch assembly while carrying the electrical key transmitter sub-assembly outside of the vehicle and check that the back door locks.
(2) Inspect the entry back door lock operating range. Hold the electrical key transmitter sub-assembly at the same height as the rear bumper upper surface and approximately 0.3 m (0.984 ft.) from the vehicle as shown in the illustration, press the lock switch of the back door opener switch assembly and check that the back door locks.
| *1 | Back Door Opener Switch Assembly (Lock Switch) |
| *a | 0.3 m (0.984 ft.) |
HINT:
- Communication may not be possible if the electrical key transmitter sub-assembly is within 0.2 m (0.656 ft.) of the rear bumper.
- If the key lock-in prevention function buzzer sounds, radio waves from the indoor electrical key antenna may be leaking from the vehicle.
- The entry lock function cannot be operated more than 3 times consecutively.

CHECK KEY LOCK-IN PREVENTION FUNCTION (VEHICLE INTERIOR)
NOTICE:
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.
(a) Check the key lock-in prevention function (vehicle interior).
(1) Turn the ignition switch off.
(2) Place the electrical key transmitter sub-assembly on a front, rear seat or luggage room floor.
(3) Close all of the doors and make sure they 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.

(a) Check the answer-back function (hazard warning light flashing).
| Entry Operation | Hazard Warning Light |
|---|---|
| Entry Lock | Flashes once |
| Entry Unlock | Flashes twice |

KEY DIAGNOSTIC MODE (Using GTS)
HINT:
- With key diagnostic mode, it is possible to check if the electrical key transmitter sub-assembly is operating properly with the selected electrical key antenna and within the selected detection area by the sounding of the wireless buzzer.
- If the buzzer sounds with [CH1] displayed but not with [CH2], the electrical key transmitter sub-assembly cannot be detected by channel 2 due to a malfunction, such as wave interference.
(a) Enter the following menus: Body Electrical / Smart Key / Utility / Communication Check(Key Diag Mode).

Break-In Period
No special break-in is necessary, but a few precautions in the first 600 miles (1,000 km) may add to the performance, economy, and life of the vehicle.
Do not race the engine. Do not maintain one constant speed, either slow or fast, for a long period of time. Do not drive constantly at full-throttle or high engine rpm for extended periods of time. Avoid unnecessary hard stops. Avoid full-throttle starts.
