Automatic transmission

Accelerator position

Your driving style influences the transmis-
sion’s shifting behavior:

Less throttle

Earlier upshifting

More throttle

Later upshifting

Kickdown

Use kickdown when you want maximum
acceleration

̈

Press the accelerator past the point of
resistance.

The transmission shifts into a lower
gear.

̈

Ease on the accelerator when you have
reached the desired speed.

The transmission shifts up again.

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
(

page 114).

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
(

page 118).

For more information on trailer towing, see
the “Operation” section (

page 192).

Emergency operation (Limp Home
Mode)

If the vehicle acceleration worsens or the
transmission no longer shifts, the trans-
mission is most likely operating in limp
home mode. In this mode only 2nd gear
and reverse gear can be activated.

̈

Stop the vehicle.

̈

Move selector lever to position P.

̈

Turn off the engine.

̈

Wait at least ten seconds before re-
starting.

̈

Move selector lever to position D (for
2nd gear) or R.

̈

Have the transmission checked at an
authorized Mercedes-Benz Light Truck
Center as soon as possible.
