2006 MERCEDES-BENZ ML350 DO NOT SHIFT GEARS

298 OperationIn the “Operation” section you will find
detailed information on operating, main-
taining and caring for your vehicle.The first 1000 miles (1500 km)
The more cautiously you treat your vehicle
during the break-in period, the more satis-
fied you will be with its performance later
on.

Drive your vehicle during the first
1000 miles (1500 km) at varying but
moderate vehicle and engine speeds.


During this period, avoid heavy loads
(full throttle driving) and excessive
engine speeds (no more than
2/3 of
maximum rpm in each gear).


Shift gears in a timely manner.


Avoid accelerating by kick-down.


Do not attempt to slow the vehicle
down by shifting to a lower gear using
the gear selector lever.


Select positions3, 2 or1 only when
driving at moderate speeds (for hill
driving).After 1000 miles (1500 km) you may
gradually increase vehicle and engine
speeds to the permissible maximum.
All of the above instructions, as may apply
to your vehicle type, also apply when driv-
ing the first 1000 miles (1500 km) after
the engine, the transfer case, the front dif-
ferential or the rear differential has been
replaced.
iAlways obey applicable speed limits.

318 OperationDriving instructions

If the transmission hunts between
gears on inclines, manually shift to a
lower gear (select 4, 3, 2 or 1).
A lower gear and reduction of speed re-
duces the chance of engine overload-
ing and/or overheating.


On very steep inclines, not manageable
with automatic transmission in1,
switch on off-road driving program
(page 248).


When going down a long hill, shift into
a lower gear and use the engine’s brak-
ing effect.
Avoid riding the brakes, thus overheat-
ing the vehicle and trailer brakes.


If the engine coolant rises to an ex-
tremely high temperature (coolant tem-
perature needle approaching the red
zone) 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 hot position.


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 re-
turn to your lane.Uncoupling the trailer

Start the engine (
page 34).

Make sure the automatic transmission
is set toP.

Set the parking brake for the vehicle
(page 52) and for the trailer.

Close all doors and the tailgate.
Detach the trailer immediately after-
ward as follows:

Disconnect all electrical plug connec-
tors.

Uncouple the trailer.
!If the trailer should begin to sway, re-
duce the vehicle’s speed immediately.
In no case attempt to straighten out the
tow vehicle and trailer by increasing
the speed.

503 Technical terms

The GVW comprises the weight of the
vehicle including fuel, tools, spare
wheel, installed accessories, passen-
gers and cargo. The GVW must never
exceed the GVWR, indicated on the
certification label located on the driv-
er’s door pillar.GVWR

Kickdown
Depressing the accelerator past the
point of resistance shifts the transmis-
sion down to the lowest possible gear.
This very quickly accelerates the vehi-
cle and should not be used for normal
acceleration needs.
