vehicle. This also includes labeling and docu-
mentation affected by their modifications.
It is their responsibility to certify that:
R the altered vehicle conforms to all applica-
ble standards and regulations affected by
the vehicle alteration
R the altered vehicle continues to comply with
the motor vehicle safety standards and
emissions regulations
R the changes or installation of accessories do
not impair the safety of the vehicle
We are not responsible for any final certifica-
tion or claims regarding product liability or
warranty claims that arise as a result of such
changes. This applies to:
R components, assemblies or systems which
have been altered
R non-compliance with emissions laws and
regulations or with vehicle safety standards
arising as a result of the alterations
R all consequences resulting form the
changed, less safe or even defective vehicle
We do not assume responsibility as the final
stage manufacturer or the consequential prod-
uct liability.
Notes on the engine radiator Even seemingly small changes to the vehicle,
such as attaching a radiator trim for winter
driving or as protection against insects, are
not permitted. Do not cover the radiator. Do
not use thermal mats, insect protection covers
or anything similar.
Doing so can cause the diagnostics system to
display inaccurate values. Some of these val-
ues are legally required and must always be
correct.
Notes for commercial vehicles without
partitions Vehicles, which are approved as commercial
vehicles (N1), do not comply with the
ISO 27956
standard in the respective current
valid version unless equipped with a partition.
The ISO 27956 Standard details the equip-
ment for correct load securing in delivery vehi-
cles. Retrofitting the partition is strongly rec-
ommended when using the vehicle for the
transport of goods, as correct load securing in
vehicles without the partition is difficult to
achieve. Genuine Mercedes-Benz parts

ces, as well as control units and sensors for
these restraint systems, may be installed in
the following areas of your vehicle:
R doors
R door pillars
R door sills
R seats
R cockpit
R instrument cluster
R center console
Do not install accessories such as audio sys-
tems in these areas. Do not carry out

qualified specialist workshop. H
Environmental note
We supply reconditioned assemblies and
parts which are of the same quality as new
parts. The same New Vehicle Limited War-
ranty applies as for new parts.
The operating safety of the vehicle could be
jeopardized if you use parts, tires and wheels
as well as accessories relevant to safety which
have not been approved by Mercedes-Benz.
This could lead to malfunctions in safety-rele-
vant systems, e.g. the brake system. Only use
genuine Mercedes-Benz parts or parts of equal
quality. Only use tires, wheels and accessories
that have been specifically approved for your
vehicle.
Mercedes-Benz tests genuine Mercedes-Benz
parts, conversion parts and accessories that
have been specifically approved for the type of
vehicle for:
R Reliability
R Safety
R Suitability
Despite ongoing market research, Mercedes-
Benz is unable to assess other parts. Even if
an independent or official approval has been
provided in exceptional cases, Mercedes-Benz
accepts no responsibility for the use of such
parts in Mercedes-Benz vehicles. 34
Introduction

Child-proof lock for sliding door
Sliding door (example: left side of the vehicle)
: Child safety bolt
2 Sliding door released
3 Sliding door secured – then make sure
that the child-proof locks are working
properly.
You can secure each sliding door individually
with the child-proof locks on the sliding doors.
A secured sliding door cannot be opened from
inside the vehicle. When the vehicle is
unlocked, the sliding door can be opened from
the outside. If the electric sliding door is
secured, only the sliding door rear controls are
deactivated. If the electric sliding door is
unlocked, you can open the electric sliding
door using the corresponding Å or Æ
sliding door button in the center console
(Y page
79). Pets in the vehicle
G
WARNING
If you leave animals unsupervised or unse-
cured in the vehicle, they may press buttons
or switches, for instance.
In this way, animals may:
R activate vehicle equipment and become
trapped, for example
R switch systems on or off and thereby
endanger other road users
Furthermore, unsecured animals may be
flung around inside the vehicle in the event
of an accident or abrupt steering or braking maneuver, and thereby injure vehicle occu-
pants. There is a risk of accident and injury.
Never leave animals unattended in the vehi-
cle.
Always secure animals properly when driv-
ing, for instance with a suitable pet carrier. Driving safety systems
Overview
In this section, you will find information about
the following driving safety systems:
R EBD ( Electronic Brake Force Distribution)
R ABS ( Anti-lock Braking System)
R BAS ( Brake A ssist System)
R ESP ®
(Electronic Stability Program) Important safety notes
If you fail to adapt your driving style or if you
are inattentive, the driving safety systems can
neither reduce the risk of accident nor over-
ride the laws of physics. Driving safety sys-
tems are merely aids designed to assist driv-
ing. You are responsible for the distance to the
vehicle in front, for vehicle speed, braking in
good time and for staying in your lane. Always
adapt your driving style to the prevailing road
and weather conditions and maintain a suffi-
cient, safe distance from other road users.
Drive carefully.
Please note that the driving safety systems
described only work optimally when the follow-
ing conditions are fulfilled:
R there is adequate contact between the tires
and the road surface.
R you use winter tires

(M+S tires) with snow
chains if necessary, when the road condi-
tions are wintry.
R the speed information determined by the
vehicle is within the legally prescribed dis-
play accuracy.
Pay particular attention to the information
regarding tires, tire tread and winter operation
under "Wheels and tires" (Y page 278). 66
Driving safety systems
Safety

Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or
taking drugs.
Emission control G
DANGER
Combustion engines emit poisonous
exhaust gases such as carbon monoxide.
Inhaling these exhaust gases is hazardous to
health and can result in poisoning. There is a
risk of fatal injury. Therefore, never leave the
engine running an enclosed space without
adequate ventilation.
Certain engine systems are designed to keep
the level of poisonous substances in exhaust
fumes within legal limits.
These systems only work optimally if they are
maintained exactly in accordance with the
manufacturer's specifications. Any work on
the engine should therefore be carried out by
qualified and authorized Mercedes-Benz tech-
nicians.
The engine settings must not be changed
under any circumstances. In addition, all spe-
cific maintenance work must be carried out at
regular intervals and in accordance with the
service requirements of the dealer listed here
on the inside title page. Details can be found
in the Maintenance Booklet. Speed limiter
G
WARNING
Exceeding the stated tire load-bearing capa-
city and the approved maximum speed
could lead to tire damage or the tire burst-
ing. There is a risk of accident.
Therefore, only use tire types and sizes
approved for your vehicle model. Observe
the tire load rating and speed rating
required for your vehicle.
As the driver, you must be aware of the maxi-
mum design speed of the vehicle and the max-
imum permissible speed based on the tires
(tire and tire pressure). In particular, also observe the tire approval regulations for each
country.
You must not exceed the speed limit for the
tires indicated by the speed rating. The speed
rating is stated in the tire tables (Y page
302).
You can permanently limit the permissible
maximum speed of your vehicle, e.g. for driv-
ing on winter tires.
Mercedes-Benz recommends that you have
the maximum permissible speed programed at
a Mercedes-Benz Commercial Van Center.
Before overtaking, take into consideration that
the engine speed limiter prevents the speed
increasing beyond the programmed permissi-
ble maximum speed. Driving abroad
Service An extensive network of authorized Mercedes-
Benz Centers is also at your disposal when you
are traveling abroad. Nevertheless, please
bear in mind that service facilities or replace-
ment parts may not always be immediately
available. The relevant workshop directories
are available from any Mercedes-Benz Com-
mercial Van Center.
Fuel In some countries, only fuels with a higher sul-
fur content are available.
Unsuitable fuel can cause engine damage. You
will find information about fuel under "Service
products and capacities"

(Y page 306).
Low-beam headlamps General notes
When driving in countries in which traffic
drives on the opposite side of the road to the
country where the vehicle is registered, you
must switch the headlamps to symmetrical
low beam. This prevents oncoming traffic from
being blinded. Symmetrical low beam does not
illuminate as large an area of the edge of the
road. Driving tips
141
Driving and parking Z

Driving on flooded roads
!
Do not drive through flooded areas. Check
the depth of any water before driving
through it. Drive slowly through standing
water. Otherwise, water could enter the
vehicle interior or engine compartment. It
can then damage the engine's or automatic
transmission's electronic components. It
can also be sucked in by the engine's air
intake connection and cause engine dam-
age.
If you have to drive on stretches of road on
which water has collected, please bear in mind
that: R the water level of standing water should not
be above the lower edge of the front
bumper
R you must not drive faster than walking
speed Driving in winter
G
WARNING
If you shift down on a slippery road surface
in an attempt to increase the engine's brak-
ing effect, the drive wheels could lose their
grip. There is an increased danger of skid-
ding and accidents.
Do not shift down for additional engine brak-
ing on a slippery road surface.
! An accumulation of snow and ice, particu-
larly when frozen, caught in the area around
the air intake slots, moving parts, the axles
and the wheel arches may:
R restrict air intake
R damage vehicle parts
R cause malfunctions by restricting the
mobility intended by the design (e.g.
reduced possible steering input).
Regularly check the vehicle and remove
snow or ice when traveling in wintry condi-
tions.
If there is any damage, inform a qualified
specialist workshop.
! Vehicles with automatic transmission may
only briefly coast in neutral position N.
Extended coasting of the wheels, e.g. when
towing, results in transmission damage. Have your vehicle winterized at a qualified spe-
cialist workshop at the onset of winter.
Drive particularly carefully on slippery roads.
Avoid sudden acceleration, steering and brak-
ing maneuvers. Do not use cruise control.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X Shift the transmission to position i.
X Try to maintain control of the vehicle using
corrective steering.
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Changes in the outside temperature are dis-
played after a short delay.
Indicated temperatures just above the freezing
point do not guarantee that the road surface is
free of ice. The road may still be icy, especially
in wooded areas or on bridges. If you do not
adjust your driving style, the vehicle may start
to skid. Always adapt your driving style and
drive at a speed to suit the prevailing weather
conditions.
You should pay special attention to road con-
ditions when temperatures are around freezing
point.
You can find further information under:
R "M+S tires" ( Y page
280)
R "Snow chains" (Y page 281)
R "Driving with summer tires" (Y page 280)
Also observe the notes under "Winter opera-
tion" (Y page 280). Driving off-road
Important safety notes G
WARNING
If you drive on a steep incline at an angle or
turn when driving on an incline, the vehicle
could slip sideways, tip and rollover. There is
a risk of an accident.
Always drive on a steep incline in the line of
fall (straight up or down) and do not turn the
vehicle. 144
Driving tips
Driving and parking

X
Thoroughly hose down the vehicle with a
gentle jet of water.
X Do not point the water jet directly towards
the air inlet grilles.
X Use plenty of water and rinse out the
sponge frequently.
X Rinse the vehicle with clean water and dry
thoroughly with a chamois.
X Do not let the cleaning agents dry on the
paintwork.
When using the vehicle in winter, remove all
traces of road salt deposits carefully and as
soon as possible.
Power washers G
WARNING
The water jet from a circular jet nozzle (dirt
blasters) can cause invisible exterior dam-
age to the tires or chassis components.
Components damaged in this way may fail
unexpectedly. There is a risk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis components replaced imme-
diately.
! Under no circumstances use power wash-
ers in the vehicle interior. The pressurized
water and associated spray produced by the
power washer could cause extensive dam-
age to the vehicle.
! When using high-pressure cleaning equip-
ment, maintain a minimum distance of
approx. 1 ft (30 cm
) between the spray noz-
zle and the vehicle parts. Do not use a
power washer with a round-jet nozzle. You
could damage the vehicle or engine parts.
! Keep the water jet moving constantly
while cleaning. This will avoid causing dam-
age to the vehicle.
Do not point the water jet at:
R door joints
R rear view camera
R air bellows
R brake hoses
R wheel balance weights
R electrical components
R electrical connections R
seals
R drive train, especially not at the inter-
mediate bearing of the propeller shaft
Cleaning the engine !
Water must not enter intake or ventilation
openings. When cleaning with high pressure
water or steam cleaners, the spray must not
be aimed directly at electrical components
or the terminals of electrical lines.
Preserve the engine after the engine has
been cleaned. Protect the belt drive system
from exposure to the preservative agent.
Also observe the information under "Power
washers"

(Y page 265).
Cleaning the paintwork !
Do not affix:
R stickers
R films
R magnetic plates or similar items
to painted surfaces. You could otherwise
damage the paintwork.
Scratches, corrosive deposits, areas affected
by corrosion and damage caused by inade-
quate care cannot always be completely
repaired. In such cases, visit a qualified spe-
cialist workshop.
X Remove impurities immediately, where pos-
sible, whilst avoiding rubbing too hard.
X Soak insect remains with insect remover
and rinse off the treated areas afterwards.
X Soak bird droppings with water and rinse off
the treated areas afterwards.
X Remove coolant, brake fluid, tree resin, oils,
fuels and greases by rubbing gently with a
cloth soaked in petroleum ether or lighter
fluid.
X Use tar remover to remove tar stains.
X Use silicone remover to remove wax.
Cleaning the windows G
WARNING
You could become trapped by the wind-
shield wipers if they start moving while
cleaning the windshield or wiper blades.
There is a risk of injury. Care
