Problems with the transmissionProblemPossible causes/consequences and M SolutionsThe acceleration ability
is deteriorating.
The transmission no
longer changes gear.The transmission is in emergency mode.
It is only possible to shift into 2nd gear and reverse gear.XStop the vehicle.XShift the transmission to position P.XSwitch off the engine.XWait at least 10 seconds before restarting the engine.XShift the transmission to position D or R.
If D is selected, the transmission shifts into 2nd gear; if R is
selected, the transmission shifts into reverse gear.XHave the transmission checked at a qualified specialist
workshop immediately.Transfer case
The vehicle has permanent 4-wheel drive
(4MATIC). Power is always transmitted to
both axles.
! Performance tests may only be carried
out on a 2-axle dynamometer. The brake
system or transfer case could otherwise be
damaged. Contact an authorized
Mercedes-Benz Center for a performance
test. Mercedes-Benz recommends that you
use an authorized Mercedes-Benz Center
for this purpose.
! If the parking brake is being tested on a
brake dynamometer, the ignition must be
switched off (SmartKey or Start/Stop
button in position 0 or 1), as ESP ®
will
otherwise automatically intervene. The test
must last a maximum of 10 seconds. The
brake system could otherwise be damaged.
LOW RANGE off-road gear
The LOW RANGE off-road gear is only
available in vehicles with the Off-Road Pro
Engineering package.
Use the LOW RANGE off-road gear:
R when driving off-road
R when fording
R when towing on uphill or downhill gradients
When LOW RANGE is engaged, the engine’s
performance characteristics and the
gearshifting characteristics of the automatic
transmission are adapted for this purpose. In
addition, ABS, ESP ®
and 4ETS specially
adapted to off-road driving will be activated.
Information about driving off-road
( Y page 173).
Information about driving safety systems in
connection with LOW RANGE ( Y page 65).Automatic transmission157Driving and parkingBA 164.8 USA, CA Edition B 2011; 1; 2, en-USd2sboikeVersion: 3.0.3.52010-04-21T15:08:44+02:00 - Seite 157Z

XLift up the cover of socket :.
i
You can also use the socket when the
ignition is switched off. An emergency cut-
out ensures that the on-board voltage does
not drop too low. If the on-board voltage is
too low, the power to the sockets is
automatically cut. This ensures that there
is sufficient power to start the engine.
115 V socket
GWarning!
The 115V AC socket operates at high voltage.
Use the 115V AC socket in the vehicle with
the same caution and prudence that you
exercise when using power outlets at home.
Keep any fluids away from the 115V AC
socket. Do not clean the socket with fluids or
tapered objects. Keep the 115V AC socket
cover in the closed position, when not in use.
Otherwise, you could suffer an electric shock
and be seriously or even fatally injured.
GWarning!
A device that you connect must have a
suitable plug that complies with U.S.
standards. Never pull on the cable to unplug
a plug from the 115V AC socket. Do not use
a damaged connection cable. The 115V AC
socket may not be connected to another
115V AC power source. Do not use converters
to a grounding plug with the 115V AC socket.
This could cause serious personal injury to
you and/or others.
GWarning!
If the 115V AC socket is damaged or torn out
of the trim, do not use or touch the 115V AC
socket. Using a 115V AC socket that is
damaged or torn out of the trim could cause
serious personal injury to you and/or others.
The 115 V AC power socket : provides an
alternating voltage of 115 V, so that small
electronic devices can be connected. These
devices, such as games consoles, chargers
and laptops, should not consume more than
a maximum of 150 W altogether.
Requirements for operation of these devices:
R 12 V power sockets in the footwell of the
second row of seats and in the stowage
compartment must be functioning
correctly ( Y page 281).
R the plug of the electronic device is plugged
into the 115 V power socket :.
R the on-board voltage is within a permissible
voltage range.
R the maximum wattage of the device to be
connected must not exceed 150 W.
XOpen flap =.XInsert the plug of the electrical device into
the 115 V power socket :.

If indicator lamp ; does not light up, please
read the chapter on malfunctions.
XTo turn off: disconnect the plug from the
115 V power socket :.282FeaturesLoading, stowing and features

Ensure that you do not pull on the cord.XClose flap =.
Possible causes of malfunction:
R the on-board voltage of the vehicle is not
within the permissible voltage range.
R the temperature of the DC/AC converter is
momentarily too high.
R some small electronic devices have a
constant nominal power of less than
150 W, but a very high inrush current.
These devices will not work. If you connect
such a device, the 115 V power socket :
will not supply it with power.
If indicator lamp ; still does not light up,
consult a specialist workshop, e.g. an
authorized Mercedes-Benz Center.
