R
draw the passengers' attention to the elec-
trical step. Wait until the electrical step is
fully extended.

R only use the grab handle and step. Only
they are designed for such a load.
R keep grab handles, access steps and entry
sills free from dirt, e.g. mud, clay, snow and
ice. Operation and obstacle detection
Electrical step
The sliding door of your vehicle can be equip-
ped with an electrical access step.
X When getting in and out of the vehicle, use
the grab handles and electrical step 0043.
Electrical step 0043automatically extends
when the sliding door is opened and retracts
when it is closed.
Electrical step 0043is equipped with an
obstruction detection device on the front
side. If the step comes into contact with an
obstacle while it is extending, it stops.
After you have removed the obstacle, you
must first close the sliding door and open it
once again so that the step can extend com-
pletely.
i If the electrical step obstructs loading,
you can prevent the step from extending
when opening the sliding door via obstacle
detection. The electrical step can then
remain retracted and a forklift or other lift- ing equipment can be moved nearer to the
cargo compartment.
Vehicles without steering-wheel buttons: if
