1, switch on off-road driving program
(Y page 185) or LOW RANGE mode
(Y page 142).
R
When going down an incline, shift into a
lower gear and use the engine’s braking
effect.
Avoid riding the brakes, thus overheating
the vehicle and trailer brakes (if so
equipped).
R
If the engine coolant rises to an extremely
high temperature when the air conditioning
is on, turn off the air conditioning system.
Engine coolant heat can be additionally
vented by opening the windows, switching
the climate control fan speed to high and
setting the temperature control to the
maximum.
R
Extreme care must be exercised since your
vehicle with a trailer will require additional
passing distance ahead than when driving
without a trailer.
Because your vehicle and trailer is longer
than your vehicle alone, you will also need
to go much farther ahead of the passed
vehicle before you can return to your lane.
Decoupling the trailer
G
Warning!
While you are coupling or decoupling a
trailer, make sure nobody locks or unlocks
the vehicle and/or opens or closes doors
or the tailgate.
The vehicle’s level could change and you
could endanger yourself and/or others as
a result.
Make sure that you do not operate the ADS
button or the vehicle level control system
when coupling/decoupling the trailer.

park position P (Y page 136).

G
Warning!
As soon as you disconnect the electrical
connection between the trailer and the
vehicle, the vehicle will lower. To help avoid
personal injury, make sure no one is near
the wheel housing or underneath the
vehicle before the electrical connection is
disconnected.
When you decouple the trailer, the vehicle
is temporarily raised because the springs
are relieved of load. Be especially careful
during this process, as you could otherwise
injure yourself and/or others. Make sure
that any persons remaining in the vehicle
do not press the switches for vehicle level
control or the ADS.
