Jeep Grand Cherokee 2020 Owner's Manual page 55

If the ignition is OFF and any door is left ajar for
10 minutes or the dimmer control is rotated all
the way up to the dome on position for
10 minutes, the interior lights will automatically
turn off.
NOTE:
Battery saver mode is canceled if the ignition is
ON.
If the headlights remain on while the ignition is
placed in the OFF position, the exterior lights will
automatically turn off after eight minutes. If the
headlights are turned on and left on for eight
minutes while the ignition is OFF, the exterior
lights will automatically turn off.
INTERIOR LIGHTS
Courtesy and dome lights are turned on when
the front doors are opened or when the dimmer
control (rotating wheel on the right side of the
headlight switch) is rotated to its farthest
upward position. If your vehicle is equipped with
Remote Keyless Entry and the unlock button is
pushed on the key fob, the courtesy and dome
lights will turn on. When a door is open and the
interior lights are on, rotating the dimmer
control all the way down, to the last (off) detent,
will cause all the interior lights to go out.
This is also known as the "Party" mode because
it allows the doors to stay open for extended
periods of time without discharging the
vehicle's battery.
Courtesy Lights
The courtesy lights can be turned on by pushing
the top corner of the lens. To turn the lights off,
push the lens a second time.
