idling or on an uphill gradient:
Move the gear selector lever to
positionP.
Set the parking brake.Maneuvering

Working on the vehicle
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 122).
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 127).
For more information on trailer towing, see
the “Operation” section (
page 211).
Warning!

When working on the vehicle, set the
parking brake and move gear selector lever
to positionP. Otherwise the vehicle could
roll away.
