Additional information
The engine will switch off in the P, D, N and S
positions as well as in manua l mode. In the P
position, the e ngine will also remain off if you
take your foot off the brake pedal. The engine
starts again when you select another se lector
lever position and take your foot off the brake
pedal.
If you select the R position during a Stop
phase, the engine will start again .
Shift from D to P quickly to prevent the engine
from starting unintentionally when shifting
through R.
You can determine for yourself if the engine
will stop or not by reducing or increasing the
amount of force you use to press the brake
pedal. For example, if you only lightly press
on the brake pedal in stop-and and-go traffic
or when turning, the engine will not switch off
when the vehicle is stationary. As soon as you
press the brake down harder, the engine will
switch off.
