RSE can be activated with the ignition in modes I or II (and when the engine is running).

See page 82 for detailed information about the various ignition modes. If a film is being played, it will stop momentarily while the engine is being started and will resume when the engine is running.

NOTE
Using RSE for more than approx.
10 minutes when the engine is not running will drain the vehicle's battery and may make the engine difficult or impossible to start.
A message will be displayed on the screen if the battery's charge level becomes too low.
