Important safety notes G
WARNING
The ultrasonic backing up aid is only designed
to assist
you and may not detect all obstacles.
It is not a substitute for paying attention.
You are always responsible for safety and
must continue to pay attention to your
immediate surroundings when parking and
maneuvering. Otherwise, you could endanger
yourself and others. G
WARNING
Make sure that no persons or animals are in
the maneuvering range. Otherwise, they
could be injured.
The ultrasonic

backing up aid is an electronic
parking aid. It indicates visually and audibly
the distance between the rear area of your
vehicle and an object.
The ultrasonic backing up aid is activated
automatically when you switch on the ignition
and engage reverse gear.
The ultrasonic backing up aid monitors the
rear area of your vehicle using four sensors in
the rear bumper. :
Sensors in the rear bumper 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 220). Side view

Corners Approximately 40 in
(approximately 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.

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

No power is transmitted to the
drive wheels.
Shifting the transfer case
General information
G
WARNING
If you do not wait for the gear change process
to complete, it may not be correctly
implemented. The transfer case may then be
in neutral and the power transmission
between the engine and the drive axles may
be disengaged. The vehicle can then move
freely, even if a gear is engaged, and may
inadvertently start moving, particularly if it is
on a slope. There is therefore a risk of an
accident. Always wait for the gear change process from
HIGH to LOW and from LOW to HIGH to
complete. Do not turn off the engine while
changing
gear

and do not shift the automatic
transmission to another gear.
Observe the relevant messages 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.

Fuses
Important safety notes
G
WARNING
Only use fuses that have been approved for
Mercedes-Benz vehicles and that have the
correct fuse rating for the systems
concerned. Do

not attempt to repair or bridge
faulty fuses. Using fuses that have not been
approved or attempting to repair or bridge
faulty fuses could cause the fuse to be
overloaded and result in a fire. Have the cause
traced and rectified at a qualified specialist
workshop.
! 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.
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.
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.
i If a fuse has blown, contact a breakdown
service or an authorized Mercedes-Benz
Center.
If a newly inserted fuse also blows, have the
cause traced and rectified at a qualified
specialist workshop, e.g. an authorized
Mercedes-Benz Center. Fuses

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. X
The 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 the Tire and Loading Information
placard. Determining the correct load limit
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".
X
Step 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
placard.
X Step 2: Determine the combined weight of
the
driver and passengers that will be riding
in your vehicle.
X Step 3: Subtract the combined weight of
the driver and passengers from XXX
kilograms or XXX lbs.
X Step 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 vehicle
