The engine stops when the selector lever is in
the positions P, D, N and S, in addition to
when in manual mode. With the selector lev-
er in position P, the engine will also remain
switched off when you take your foot off the
brake pedal. In order to start the engine up
again the accelerator must be pressed, or an-
other gear engaged or the brake released.
If the selector lever is placed in position R
during the stopping phase, the engine will
start up again.
