that there may be something in the
rear seat. The feature is active only once each time
the vehicle is turned on and off, and will
require reactivation by opening and closing

alert even when there is nothing in the rear
seat; for example, if a child entered the
vehicle through the rear door and left the

cushion.

the seat belts are properly routed and
attached, and are not twisted.

for a certain number of miles or degrees of
turn before needing a signal from the GPS
satellites. When the compass display shows

Leaving electrical equipment plugged in
for an extended period of time while the
vehicle is off will drain the battery.
