Emergency Power System On

If the power system cannot be turned on using the normal starting procedure, you may be able to turn it on using the emergency starting procedure below.
Do not use this procedure if it is not an emergency.

1. Make sure the parking brake is applied.
2. Check that the transmission is in P, then set the power mode to ACCESSORY.
3. Firmly depress the brake pedal, then press and hold the POWER button for at least 15 seconds.

This should be considered a system malfunction even if you are able to turn the power system on using the above procedure.
Have your vehicle checked by a dealer immediately.
