Trailer towing
Hill
When you start driving uphill or downhill, trailers
may tilt or sway sooner than when driving ona
level surface. If small swaying movements have
already occurred, you can stabilize the trailer by
firmly braking immediately. Never attempt to
“straighten out” the trailer by accelerating.
Conventional drive system: Downshift before
driving on hills to utilize the engine braking ef-
fect SA.
Plug-in hybrid drive system: Reduce the speed
and use the recuperation braking effect
=> page 114 to relieve the brakes > A.
Brakes
When using a trailer with overrun brakes, first
brake gently then quickly. This reduces the risk of
jerking while braking if the trailer wheels lock up.
Engine coolant temperature
Pay attention specifically to the coolant tempera-
ture display when there are high outside temper-
atures, and when driving on long inclines
=> page 14. Shift to a higher gear in a timely man-
ner.
Z\ WARNING
Constant braking causes the brakes to over-
heat and can substantially reduce braking per-
formance, increase braking distance, or cause
complete failure of the brake system.

— The image in the display is an enlarged and
distorted image. Under certain circumstan-
ces, objects may appear different and un-
clear on the display. This is especially true if
there are objects that do not touch the
ground, such as the bumper of a parked ve-
hicle or the rear of a truck. Drive with spe-
cial care and do not use the image if neces-
sary.
— Applies to vehicles with air suspension: The
accuracy of the orientation lines and green
surfaces in the display decreases when the
