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.

Towing a trailer
If you tow a trailer, note the following
points:

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.


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 positionP.

Turn off the engine.

Wait at least ten seconds before re-
starting.

Move selector lever to position D (for
