WARNING
An unsecured vehicle can begin to move
and possibly roll away. There is risk of an acci‐
dent. Before exiting, secure the vehicle against
rolling.
In order to ensure that the vehicle is secured
against rolling away, observe the following:
▷Set the parking brake.▷On uphill grades or on a downhill slope,
turn the front wheels in the direction of the
curb.▷On uphill grades or on a downhill slope,
also secure the vehicle, e.g., with a wheel
chock.◀Selector lever, selector lever positions
Overview▷R: reverse gear.▷N: neutral.▷ Center position, forward position.▷+: manual upshifting.▷-: manual downshifting.▷D/S: switch between drive mode and se‐
quential mode.
Engaging a selector lever position
Press on the brake pedal and pull or push the
selector lever in the corresponding direction.
As soon as the selector lever is released, it re‐
verts to the center position. In position R, the
selector lever locks.
The engaged selector lever position is dis‐
played in the instrument cluster and on the se‐
lector lever.
If a selector lever position is engaged, the vehi‐
cle may start rolling, after the brake is released,
for example on downhill slopes. Thus, drive off
immediately after releasing the brake.
