Automatic transmission
Rocking the vehicle
Rocking the vehicle by shifting betweenD
andR can help free a vehicle stuck in mud
or snow. The engine control system of this
vehicle electronically limits shifting
betweenD andR to very low speeds
(i.e. approx. 2 mph). To shift betweenD
andR, move the gear selector lever past
the resistance point up or down.
Hill start assist system
On uphill grades, the hill start assist
system maintains the pressure in the
brake system for approximately
one second after you have released the
brake pedal. Therefore, you can start off
smoothly without the vehicle moving im-
mediately after releasing the brake pedal.
The hill start assist system is inactive

on driving downhill

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

Manually shift to a lower gear range
(page 187) if the transmission hunts
between gears on inclines.
A lower gear range and reduction of
speed reduces the chance to overload
or overheat the engine.
For more information on trailer towing, see
the “Operation” section (
page 314).
Warning!
G
The hill start assist system is not designed
to function as a parking brake and does not
prevent the vehicle from moving when
parked on an incline.
Always set the parking brake in addition to
shifting to park position
P.
iIf the ESP
® has switched off due to a
malfunction, the hill start assist system
is also unavailable.
Warning!
G
When working on the vehicle, set the
parking brake and shift to park positionP.
Otherwise the vehicle could roll away.

!Because off the ESP’s
® automatic
operation, the engine must be shut off
(SmartKey or SmartKey with
KEYLESS-GO* in starter switch
position1) when testing the brakes on
a brake test dynamometer and such
testing should be no longer than
10 seconds. Active braking action
through the ESP
® may otherwise
seriously damage the front or rear axle
brake system.
Operational or performance tests with
the engine running must only be con-
ducted on a two-axle dynamometer.
Otherwise, the transfer case or the
brake system can be damaged, which
is not covered by the Mercedes-Benz
Limited Warranty.
iThe vehicle is equipped with full-time
four-wheel drive. Both the front and
rear axles are powered at all times
when the vehicle is being operated.

incoming light is not aimed directly at sen-
sors in the interior rear view mirror.
The interior rear view mirror and the exterior
rear view mirror on the driver’s side do not
react, for example, when transporting cargo

G
In case of an accident, liquid electrolyte may
escape from the mirror housing if the mirror
glass breaks.
Electrolyte has an irritating effect. Do not
allow the liquid to come into contact with
eyes, skin, clothing, or respiratory system.
In case it does, immediately flush affected
area with water, and seek medical help if
necessary.
!Electrolyte drops coming into contact
with the vehicle paint finish can be
completely removed only while in the
liquid state and by applying plenty of
water.Warning!
G
Exercise care when using the passen-
ger-side exterior rear view mirror. The mirror
surface is convex (outwardly curved surface
for a wider field of view). Objects in mirror
are closer than they appear. Check your
interior rear view mirror or glance over your
shoulder before changing lanes.

Rear window defroster
The rear window defroster uses a large
amount of power. To keep the battery
drain to a minimum, switch off the defrost-
er as soon as the rear window is clear. The
defroster is automatically deactivated
after approximately 6 to 17 minutes of
operation depending on the outside tem-
perature.Warning!
G
Any accumulation of snow and ice should be
removed from the rear window before driv-
ing. Visibility could otherwise be impaired,
endangering you and others.
!If the rear window defroster switches
off too soon and the indicator lamp
starts flashing, this means that too
many electrical consumers are operat-
ing simultaneously and there is insuffi-
cient voltage in the battery. The system
responds automatically by deactivating
the rear window defroster.
As soon as the battery has sufficient
voltage, the rear window defroster au-
tomatically turns itself back on.
