Locking the vehicle
If you are unable to lock the vehicle with
the remote control, lock it with the me-
chanical key as follows:
̈ Close the passenger doors and the lift-
gate.
̈ Press the upper part of the central
locking button in the cockpit
(
page 89).
̈ Check to see whether the locking
knobs on the passenger doors are still
visible. If necessary push them down
manually.
̈ Lock the liftgate if necessary from in-
side (
page 87).
̈ 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.
Recycling of batteries is the preferred
method of disposal. Many states require
sellers of batteries to accept old batteries
for recycling.
