If the vehicle has been unlocked using the emergency key blade or the smart key is not detected by the vehicle, it will be necessary to use the keyless start backup to disarm the alarm and start the engine. The following process must be followed in this event:
- Press the stop/start switch, if the KVM fails to locate the smart key, the message 'SMART KEY NOT RECOGNISED, REPOSITION OR PLACE AS SHOWN AND PRESS START BUTTON' shall be displayed in the IC message center.
- Position the smart key against the left side of the lower steering column cowl with the smart key switches facing downwards. The location of the IAU is denoted by ribs.
- Press the stop/start switch with the brake/clutch pedal depressed to start the engine.
This process bypasses the data exchange between the KVM and the BCM/GWM; this is an inductive process and will operate even if the battery in the smart key is discharged. A transponder within the smart key is detected by the IAU. The IAU communicates this code with the BCM/GWM via a LIN (Local Interconnect Network) bus connection. The BCM/GWM then initiates the vehicle start process in the normal manner.
