Keys and Remote Control
Remote Starting the Vehicle
Note: You must press each button within three seconds of each other.
Your vehicle will not remote start and the horn will not sound if you do
not follow this sequence.
1. Press the lock button to lock all the doors.
2. Press the remote start button twice. The exterior lamps will flash
twice.
The horn will sound if the system fails to start, unless quiet start is on.
Quiet start will run the blower fan at a slower speed to reduce noise. You
can switch it on or off in the information display. See the Information
Displays chapter.
Note: If you remote start your vehicle with an integrated keyhead
transmitter, you must switch the ignition on before driving your vehicle.
If you remote start your vehicle with an intelligent access transmitter,
you must have a programmed intelligent access key inside your vehicle
and press the START/STOP button on the instrument panel once while
applying the brake pedal before driving your vehicle.
The power windows will be inhibited during the remote start and the
radio will not turn on automatically.
The parking lamps will remain on and your vehicle will run for 5, 10, or
15 minutes, depending on the setting. See the Information Displays
chapter to select the duration of the remote start system.
Extending the Vehicle Run Time
Repeat Steps 1 and 2 with your vehicle still running to extend the run
time for another remote start duration. If the duration is set to last
10 minutes, the duration will extend by another 10 minutes beginning
after what is left of the first activation time. For example, if your vehicle
had been running from the first remote start for five minutes, your
vehicle will continue to run now for a total of 15 minutes.
Wait at least five seconds before remote starting after a vehicle
shutdown.
