From the manual - this is for a 2013 but should be the same I would suspect?
The sports bar reading lights (available on four-door
models) can be turned on by pressing the switches,
located on either side of the lens. Press a switch a second
time to turn the light off.
PS also this - do you have the dimmer set?
When a door is open and the interior lights are on,
rotating the dimmer control to the extreme bottom position
will cause all the interior lights to turn off. 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.
