OPERATION AREA

The remote engine start operating range is approximately 60 m (197 ft) from the vehicle but not inside the Nissan Murano vehicle.

REMOTE ENGINE START FUNCTION

The remote engine start function is activated when the lock button of the Intelligent Key is pressed and released, and then within 5 seconds, the remote engine start button is pressed and held for at least 2 seconds. At this time, a start signal is transmitted from the Intelligent Key to the BCM via the remote keyless entry receiver.
When the BCM receives the lock signal, it locks all doors, flashes the hazard lamps and chirps the horn (the horn will chirp only if the answer back horn feature is activated).
When the BCM receives a successful remote engine start signal, the turn signals will flash once and the parking/tail lamps will come on.
To enter normal engine run mode from inside the Nissan Murano vehicle, depress and hold the brake pedal then press the ignition switch.
To cancel the remote engine start mode away from the Nissan Murano vehicle, press the remote engine start button on the Intelligent Key.
Once the vehicle has been started using the remote engine start feature, it will remain running for 10 minutes. Extended run time can be added to the initial 10 minute running time by first pressing and releasing the lock button and then within 5 seconds, pressing and holding the remote engine start button for at least 2 seconds. The turn signals will flash once and an additional 10 minutes of running time will be added. The additional 10 minutes start when the extended run time is activated. Extended time can only be added once for a maximum run time of up to 20 minutes.
