Automatic transmission
Towing a trailer
If you tow a trailer, note the following
points:
ț Manually shift to a lower gear range
(4, 3, 2, 1), if the transmission hunts
between gears on inclines
(
୴ page 121).
A lower gear range and reduction of
speed reduces the change to overload
or overheat the engine.
ț At very steep inclines switch transfer
case to LOW RANGE mode
(
୴ page 125).
For more information on trailer towing, see
the “Operation” section (
୴ page 206).
Emergency operation (Limp Home
Mode)
If vehicle acceleration worsens or the
transmission no longer shifts, the trans-
mission is most likely operating in limp
home (emergency operation) mode. In this
mode only second gear and reverse gear
can be activated.
̈ Stop the vehicle.
̈ Move gear selector lever to position P.
̈ Turn off the engine.
̈ Wait at least ten seconds before
restarting.
̈ Restart the engine.
̈ Move selector lever to position D
(for second gear) or R.
̈ Have the transmission checked at an
authorized Mercedes-Benz Light Truck
Center as soon as possible.
