Keyless Start Backup
Smart Key Positioning To The Immobilizer Antenna Unit
It is necessary to use the keyless start backup to disarm the alarm and start the engine in the following cases:
- The vehicle has been unlocked using the emergency key.
- The smart key is not detected by the vehicle.
The following process must be followed in this event:
- Operate the ignition switch if the Remote Function Actuator (RFA) fails to locate the smart key. The message 'Smart Key Not Recognized - Position Of Place As Shown And Press Start Button' will be displayed in the Instrument Cluster (IC) message center.
- Position the smart key against the bottom of the lower steering column with the smart key switches facing downward. The location of the Immobilizer Antenna Unit (IAU) is denoted by ridges on the shroud.
- Operate the ignition switch with the brake or clutch pedal pressed to start the engine.
This process bypasses the data exchange between the RFA and the Body Control Module/Gateway Module (BCM/GWM). This is an inductive process and will operate even if the battery in the smart key is discharged. The transponder within the smart key is detected by the IAU. The IAU communicates this code with the BCM/GWM via a Local Interconnect Network (LIN) connection. The BCM/GWM then initiates the vehicle start process in the normal manner.
