gate.
̈ Press the upper part of the central
locking button in the cockpit
(

̈ Check to see whether the locking
knobs on the passenger doors are still
visible. If necessary push them down
manually.

side (

̈ Lock the driver’s door with the me-
chanical key.
Changing batteries
If the batteries in the remote control are
discharged, the vehicle can no longer be
locked or unlocked. It is recommended to
have the batteries replaced at an autho-
rized Mercedes-Benz Light Truck Center.
Batteries contain materials that can harm
the environment if disposed of improperly.
