Driving tips General driving tips
Drive carefully and maintain a suitable dis-
tance from the vehicle in front. Avoid frequent
and sudden acceleration as well as abrupt
braking.
During partially electric driving, pulling away
and acceleration, the electric motor supports the internal combustion engine.
During overrun in transmission position Dand
braking, the electric motor operates as an
alternator.
To reduce fuel consumption, use:
R recuperative braking (Y page 269)
R overrun mode (Y page 280) or extended
overrun mode (Y page 280)
For further information on the ECO start/stop
function; see (Y page 279).
Additional driving tips (Y page 211).
