position indicated by the arrow.
Fuel filler flap1 opens slightly.
Open fuel filler flap1 completely.
Turn fuel filler cap2 counterclock-
wise and hold on to it until possible

!The fuel filler cap is tethered to the fuel filler
neck. Do not drop the cap. It could damage the
vehicle paint finish.

locking your vehicle as the flap locking pin
prevents closing after you have locked the
vehicle.

535 Practical hints
Battery
Connect the positive lead to the posi-
tive terminal and fasten it’s cover
(
page 533).
Connect the negative lead to the nega-
tive terminal (
page 533).
Charging the battery
If the battery is discharged, the battery can

lead. Recycling of batteries is the preferred
method of disposal. Many states require
sellers of batteries to accept old batteries
for recycling.
!Never invert the terminal connections!
iThe following procedures must be carried
out following any interruption of battery power
(e.g. due to reconnection):

Synchronize the power folding exterior rear
view mirrors* (
page 209).

adapted for Mercedes-Benz vehicles and
tested and approved by Mercedes-Benz is
available, permitting the charging of the
battery in its installed position. Contact an
authorized Mercedes-Benz Light Truck
