Troubleshooting Alerts
Your vehicle has detected an attempt to park on a slope of 10% grade or greater while Trailer Mode is active. This
alert displays whenever Trailer Mode is active and your vehicle is parked on a steep slope, even if no trailer is
attached.
What to do:
• No trailer attached: Exit Trailer Mode manually via your vehicle touchscreen, so the alert no longer displays when
parking on steep slopes without a trailer.
◦ For more information, see Trailer Mode in
• Trailer attached: It is recommended that you park your vehicle and trailer in a more level area.
◦ The parking brake may not hold both vehicle and trailer on slopes of 10% grade or greater.

Electrical system backup power is unavailable
Vehicle will consume more energy while idle
What this alert means:
The backup power source for the electrical system, the low voltage battery, is not available or cannot provide the

preserving energy for essential functions.
You may also notice that your vehicle consumes more energy than usual when you are not driving it, or that your
vehicle displays a lower projected range than you would normally expect after charging. This is normal vehicle
behavior when this alert is present, and it will continue until the backup power source is restored.
There is a chance that an issue affecting the primary power source could cause your vehicle to shut down
unexpectedly.
What to do:
It is recommended that you limit or avoid the use of any nonessential features. This can help your vehicle maintain
adequate electrical power for essential functions.
It is recommended that you schedule service at your earliest opportunity, so the backup power source for the
electrical system can be restored.
