N The yellow ABS warning lamp is lit while the engine is running.
ABS has been deactivated due to a malfunction. BAS, hill start assist and ESP
®
as well as its driving safety systems, for example, are therefore also deactiva-
ted.
ATTENTION ASSIST is deactivated and other driving systems could be automati-
cally deactivated.
G WARNING
The brake system continues to function normally, but without the functions lis-
ted above. The wheels could therefore lock prematurely if you brake hard, for
example.
This causes steerability and braking to be greatly impaired. The braking distance
may increase in emergency braking situations.
If ESP ®
is not operational, ESP ®
will not stabilize the vehicle.
There is an increased risk of skidding and accidents.
X Switch the engine off, wait briefly and start the engine again.
X Check if the display message has disappeared and ESP ®
is operational.
X If the display message continues to be displayed:
R Drive on with care.
R Visit a qualified specialist workshop immediately.
If the ABS control unit is faulty, there is also a possibility that other systems will
be restricted or unavailable. ÷

The cigarette lighter socket can be used for
accessories with a maximum power consump-
tion of 180 W

(15 A).
If you use the sockets to connect accessories
for long periods when the engine is switched
off, the starter battery may discharge. An
emergency cut-off ensures that the on-board
voltage does not drop too low. If the on-board
voltage is too low, power to the socket is auto-
matically cut. This ensures that there is suffi-
cient power to start the engine. 12 V socket
When the key is turned to position 1 in the
ignition lock, the sockets can be used for accessories with a maximum power consump-
tion of

180 W (15 A).
If you use the sockets for long periods when
the engine is switched off, the starter battery
may discharge. If the on-board voltage is too
low, it might then no longer be possible to
start the engine.
The socket in the center console and the
socket in the side of the cargo compartment
are not automatically deactivated if the on-
board voltage is low. The additional sockets in
the rear compartment are automatically deac-
tivated if the on-board voltage is low.
Additional 12 V sockets may be located in the
rear corner trim next to the tailgate and in the
side trim on the left and right-hand sides.
X Lift up the cover of socket :. Mobile communications equipment
G
WARNING
If you operate information and communica-
tion devices while driving, you may be dis-
tracted from the traffic conditions. You
could even lose control of the vehicle. There
is a risk of an accident.
Only operate these devices when the vehicle
is stationary.
Observe the legal requirements for the country
in which you are currently driving when operat-
ing mobile communication equipment.
Please remember, a navigation system does
not supply information on the load-bearing
capacity of bridges or the overhead clearance
of underpasses. The driver remains responsi-
ble for safety at all times.
You and others can suffer health-related dam-
age through electromagnetic radiation. By
using an exterior antenna, a possible health
risk caused by electromagnetic fields, as dis-
cussed in scientific circles, is taken into
account. Only have the exterior antenna instal-
led by a qualified specialist workshop.
Failure to observe the Mercedes-Benz installa-
tion specifications can result in the invalida-
tion of your vehicle's operating permit.

Always transport loads in the cargo com-
partment and with the seat backrests folded
up and properly locked in position.
X Always place the load against the backrests
of the front or rear seats.
X Move large and heavy loads as far towards
the front of the vehicle as possible against
the front or rear seats. Stow the load flush
with the rear or front seats.
X Always additionally secure the load with
suitable load-securing aids or tie downs.
Observe the following notes:
R Do not stack loads higher than the upper
edge of the backrests.
R Transport loads behind seats that are not
occupied.
R If the rear bench seat is not occupied, insert
the seat belts crosswise into the buckle of
the opposite seat belt. Cargo compartment variations
You can vary the cargo compartment accord-
ing to your transportation requirements as fol-
lows:
R by folding the seat backrests forward to the
table position.
R by removing the rear bench seat.
You will find information about rear bench
seats in the "Rear bench seats" section
( Y page

Important safety notes
G
WARNING
If you attach the tie-down incorrectly when
securing the load, the following may occur in
the event of abrupt changes in direction,
braking maneuvers or an accident:
R the cargo tie-down rings may become
detached or the tie-down may tear if the
permissible load is exceeded
R the load may not be restrained. This may cause the load to slip, tip over or
be tossed about, striking vehicle occupants.
There is a risk of an accident and injury.
Always tension the tie-downs in the proper
manner and only between the described
cargo tie-down rings. Always use tie-downs
designed specifically for the loads.
! Observe the information on the maximum
loading capacity of the individual cargo tie-
down points.
If you use several cargo tie-down points to
secure a load, you must always take the
maximum loading capacity of the weakest
cargo tie-down point into account.
If you brake hard, for example, the forces
acting could be up to several times the
weight force of the load. Always use multi-
ple cargo tie-down points in order to distrib-
ute the force absorption. Load the ancho-
rages evenly.
As the driver, you are responsible for ensuring
that: R The load is secured against slipping, tipping,
rolling or falling off in normal traffic condi-
tions, should the vehicle swerve to avoid an
obstacle, in the event of maximum full-stop
braking and on poor road surfaces
R The applicable requirements and guidelines
relating to load-securing practices are met
If this is not the case, this may constitute a
punishable offense, depending on local leg-
islation and any ensuing consequences.
Always observe the legal requirements for
the country you are currently in.
Make sure that the load is secure before every
journey and at regular intervals during a long
journey. Correct an incorrectly or inadequately
secured load if necessary.
Always observe the operating instructions or
the notes of the lashing strap manufacturer for
the operation of the lashing strap.
You can obtain information about securing the
load correctly from the manufacturer of the
load securing aids or tie down for securing the
load. Also observe the safety information in
the loading directions ( Y page 242).
X Fill spaces between the load and the cargo
compartment walls or wheel housings (form-244

locking). Use rigid load securing aids, such
as wedges, wooden fixings or padding.
X Attach secured and stabilized loads in all
directions to the cargo tie-down rings and
the guide rails in the rear compartment.
Only use tie downs, such as lashing nets
and lashing straps, that have been tested in
accordance with current standards.
When securing a load, always use the clos-
est cargo tie-down rings and pad sharp
edges for protection. Cargo tie-down points (example: Cargo Van)
Fixed cargo tie-down points on the floor
:
Guide/load rails
; Cargo tie-down rings
If your vehicle is equipped with guide/loading
rails : in the floor, you can place lashing rods
directly in front of and behind the load. The
lashing rods directly absorb the potential shift-
ing forces.
Securing loads on the cargo compartment
floor by lashing them down is only recommen-
ded for lightweight loads. Place non-slip mats
(anti-slip mats) under the load to increase load
security.
Spread the load evenly across the cargo tie-
down points/cargo tie-down rings. You will
find information on the maximum loading capacity of the cargo tie-down points under
"Cargo tie-down points and carrier systems"
(Y page
313).
Do not attempt to modify or repair the cargo
tie-down points/cargo tie-down rings or tie
downs. Read the information on qualified spe-
cialist workshops: (Y page 32).

floor Lashing angle for optimal load securing (example)
d
Vertical to the cargo compartment floor
e Cargo compartment floor
: Direction of propagation with 75° lashing
angle
; Direction of propagation with 45° lashing
angle
The lashing angle is between the cargo com-
partment floor and the tie downs. For optimal
load securing in accordance with the
ISO 27955 standard, the lashing angle must
be between 45° ; and 75° :. The maximum
nominal tension load of

350 daN for the cargo
tie-down rings in the cargo compartment floor
or in the guide rails may not be exceeded.
Note for commercial vehicles (vehicle cate-
gories N1) without partition
Vehicles that are approved as commercial
vehicles (vehicle category N1) do not meet the
ISO 27956 standard in the currently valid ver-
sion without a partition. The ISO 27956 stand-
ard describes the equipment for correctly
securing a load in delivery vehicles. When
using the vehicle for the transport of goods,
the retrofitting of the partition is strongly rec-
ommended as it is difficult to secure loads cor-
rectly in vehicles without a partition. Securing loads

WARNING
The load protection net alone cannot
restrain or secure heavy objects, luggage or
heavy loads. In the event of abrupt changes
in direction, braking maneuvers or an acci-
dent, you may be struck by unsecured loads.
There is a risk of injury, possibly even fatal.
Always stow objects in such a way that they
cannot be tossed about. Secure objects, lug-
gage and loads to prevent them slipping or
tipping over, e.g. by lashing them down,
even when using the load protection net. G
WARNING
If vehicle occupants are seated behind a
load protection net, they may be squeezed
up against the load protection net. There is
a risk of injury, particularly in the event of
braking maneuvers or abrupt changes in
direction.
Never allow vehicle occupants to sit behind
the load protection net.
The load protection net borders the cargo
compartment. It protects vehicle occupants
from light objects and/or luggage slipping or
tipping over. Always observe the notes on
securing loads
(Y page 244).
You can install the load protection net at an
angle behind the front seats or behind the first
row of back seats. Upper retainer
