Shift rangesHHIGH
Position for all normal on-road
driving conditions.LLOW
Low-range position for driving off-
road.
Also for use on steep uphill or
downhill gradients, especially
when towing a trailer.
! When the transfer case is in the
off-road driving position LOW
range, the automatic
transmission does not shift up,
even when the engine has
reached the overrevving limit.
There is then a risk of engine
damage. Make sure that you do
not exceed the maximum
permissible engine speed.
The vehicle travels around half the
speed of on-road driving range
HIGH . The drive power is
correspondingly higher.NNeutral
Neutral position.
No power is transmitted to the
drive wheels.
Shifting the transfer case
General notes
GWarning!
Always wait until the procedure of shifting
from HIGH to LOW – and from LOW to HIGH
– has been entirely completed. During this
procedure do not turn off the engine or shift
the automatic transmission into another gear.
If you do not wait until the shifting procedure
has been entirely completed then it might not
be correctly performed. The transfer case
might be in neutral, thus interrupting the
transfer of power between the engine and the
drive axle.
The vehicle is then freely movable, even if a
gear has been selected, and could
unintentionally be set into motion –
particularly on up – or downhill grades. This
could lead to an accident and cause injury to
yourself and others.
Please observe related messages appearing
in the multifunction display.:Current shift range;Current transfer case position
Current shift range : and transfer case
position ; are shown in the instrument
cluster multifunction display.
The switch for the transfer case is on the
lower section of the center console.

Range of the sensors
The sensors must be free of dirt, ice and
slush; otherwise they may not function
correctly. Clean the sensors regularly, taking
care not to scratch or damage them
( Y page 224).

Top view
Sensors
CenterApprox. 59 in (approx.
150 cm)CornersApprox. 40 in (approx.
100 cm)
! When parking, pay particular attention to
objects above or below the sensors, such
as flower pots or trailer towbars. The
ultrasonic backing up aid does not detect
such objects when they are in the
immediate vicinity of the vehicle. You could
damage the vehicle or the objects.
Ultrasonic sources such as an automatic
car wash, a lorry's compressed-air brakes
or a pneumatic drill could cause the
ultrasonic backing up aid to malfunction.
Minimum distanceCenterApprox. 8 in (approx.
20 cm)CornersApprox. 8 in (approx.
20 cm)
If there is an obstacle within this range, all
warning displays flash and a warning tone
sounds. If the distance falls below the
minimum, the distance may no longer be
shown.
Warning displays
The warning display shows the distance
between the sensors and the obstacle.
The warning display is in the rear
compartment next to the rear door.
The warning display is divided into four yellow
and two red segments :. The ultrasonic
backing up aid is ready for use when you hear
a warning tone and segment ; lights up
briefly.
One or more segments : light up as the
vehicle approaches an obstacle, depending
on the distance from the obstacle.

:Towing eye, rear
Towing the vehicle with both axles on
the ground
It is important that you observe the safety
instructions when towing away your vehicle
( Y page 240).
GWarning
With the engine not running, there is no power
assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the
vehicle. Adapt your driving accordingly.
XSwitch on the hazard warning lamps
( Y page 93).
i
When towing with the hazard warning
lamps switched on, use the combination
switch as usual to signal a change of
direction. In this case, only the turn signals
for the desired direction flash. When the
combination switch is reset, the hazard
warning lamps start flashing again.
XTurn the key to position 2 in the ignition
lock.XWhen the vehicle is stationary, depress the
brake pedal and keep it depressed.XShift the transfer case to neutral position
N (Y page 126).XShift the automatic transmission to
position N.XRelease the brake pedal.XRelease the parking brake.
i
The transmission can only change gear
when the battery has sufficient charge.
If you cannot move the selector lever to N,
you must remove the propeller shafts to the
driven axles.
Transporting the vehicle
Use the towing eyes to pull the vehicle if it
needs to be transported on a trailer or
transporter.
XTurn the key to position 2 in the ignition
lock.XMove the selector lever to N.XShift the transfer case to neutral position
N (Y page 126).
As soon as the vehicle is loaded:
XPrevent the vehicle from rolling away by
applying the parking brake.XShift the automatic transmission to
position P.XTurn the key in the ignition lock to position
0 and remove the key from the ignition
lock.XSecure the vehicle.
! Only lash the vehicle down by the wheels
or wheel rims, not by parts of the vehicle
such as axle or steering components.
Otherwise, the vehicle could be damaged.
Recovering a vehicle that has become
stuck
! Pull away smoothly, slowly, and in a
straight line when pulling out a vehicle that
has become stuck. Excessive tractive
power could damage the vehicles.
If the drive wheels get trapped on loose or
muddy ground, recover the vehicle with the
utmost care, especially so if the vehicle is
laden.
Towing and tow-starting241Roadside AssistanceZ

Never attempt to recover a vehicle with a
trailer attached.
Pull out the vehicle backwards, if possible,
using the tracks it made when it became
stuck.
Towing in the event of malfunctions
General notes
! If you are removing the propeller shaft,
use M10 nuts as spacers on the M8 bolts
and secure them with M8 nuts.
New self-locking nuts must be used when
the propeller shafts are refitted.
XObserve the safety notes as you do so
( Y page 240).
i
Consult an authorized Mercedes-Benz
Center.
Engine damage, gear damage or
electrical malfunctions
XMove the selector lever to N(Y page 122).XShift the transfer case to neutral position

axle raised and with wheel rollers under the
front axle.
Electrical fuses
Important safety notes
The fuses in your vehicle serve to close down
faulty circuits. If a fuse blows, all the
components on the circuit and their functions
stop operating.
GWarning
Only use fuses approved by Mercedes-Benz
with the specified amperage for the system in
question and do not attempt to repair or
bridge a blown fuse. Using other than
approved fuses or using repaired or bridged
fuses may cause an overload leading to a fire,
and/or cause damage to electrical
components and/or systems. Have the cause
determined and remedied by an authorized
Mercedes-Benz Center.
Blown fuses must be replaced with fuses of
the same rating, which you can recognize by
the color and value. The fuse ratings are listed
in the fuse allocation chart. An authorized
Mercedes-Benz Center will be happy to
advise you.
i If a fuse has blown, visit a breakdown
service or an authorized Mercedes-Benz
Center.
If the newly inserted fuse also blows, have the
cause traced and rectified at a qualified
specialist workshop, e.g. an authorized
Mercedes-Benz Center.
! Only use fuses that have been approved
for Mercedes-Benz vehicles and which
have the correct fuse rating for the system
concerned. Otherwise, components or
systems could be damaged.

vehicle-specific and may differ from that in
the illustration. You can find the valid
maximum permissible gross vehicle weight
rating for your vehicle on the Tire and
Loading Information placard.XThe Tire and Loading Information placard
gives you details on maximum permissible
gross vehicle weight rating :: "The gross
weight of occupants and luggage must
never exceed XXX kilograms or XXX
pounds."
The gross weight of all vehicle occupants,
cargo, luggage and trailer load/noseweight (if
applicable) must not exceed the specified
value.
Number of seats
i The specifications shown on the Tire and
Loading Information placard in the
illustration are examples. The number of
seats is vehicle-specific and can differ from
the details shown. The number of seats in
your vehicle can be found on the Tire and
Loading Information placard.
Maximum number of seats : determines the
maximum number of occupants allowed to
travel in the vehicle. This information can be
found on Tire and Loading Information
placard.
Determining the maximum load
Step-by-step instructions
The following steps have been developed as
required of all manufacturers under Title 49,
Code of U.S. Federal Regulations, Part 575
pursuant to the "National Traffic and Motor
Vehicle Safety Act of 1966".
XStep 1: Locate the statement "The
combined weight of occupants and cargo
should never exceed XXX kg or XXX lbs." on
your vehicle's tire and loading information
table.XStep 2: Determine the combined weight of
the driver and passengers that will be
traveling in your vehicle.XStep 3: Subtract the combined weight of
the driver and passengers from XXX
kilograms or XXX lbs.XStep 4: The resulting figure equals the
available amount of cargo and luggage load
capacity. For example, if the "XXX" amount
equals 1400 lbs and there will be five 150
lbs passengers in your vehicle, the amount
of available cargo and luggage load
capacity is 650 lbs (1400 - 750 (5 x 150) =
650 lbs).Loading the vehicle257Wheels and tiresZ
