Smart Access System & Push Button Start (Continued)
Vehicle Starting/Stopping
The smart key has replaced the conventional metal cut key, and the power
button with an integral status indicator light has replaced the ignition switch.
The smart key only needs to be in proximity to the vehicle.
•
With the brake pedal released, the first push of the power button
operates the accessory mode, the second push operates the ignition-on
mode, and the third push turns the ignition off again.

Starting the vehicle takes priority over all other ignition modes and is
accomplished by depressing the brake pedal and pushing the power
button once. To verify the vehicle has started, the power button status
indicator light is off and the READY light is illuminated in the
instrument cluster.
•
If the internal smart key battery is dead, it cannot communicate with the
vehicle. In order for the vehicle to recognize the smart key, the driver
must hold the smart key next to the power button while pushing.
•
Once the vehicle has started and is on and operational (READY-ON),
the vehicle is shut off by bringing the vehicle to a complete stop, placing
the gearshift lever in Park, and then depressing the power button once.
