WARNING
If you open the rear-end doors 90°, the rear
lighting systems are no longer visible. The
vehicle will then be difficult for other road
users to see or will not be seen by them at
all, particularly if it is dark or visibility is
poor. There is a risk of an accident.
You should therefore ensure in this and simi-
lar situations that the vehicle is visible from
the rear in accordance with the relevant
national regulations, by using the warning
triangle, for instance. Exterior lighting

Important safety notes
G
WARNING
Bulbs, lamps and connectors can get very
hot when operating. If you change a bulb,
you could burn yourself on these compo-
nents. There is a risk of injury.
Allow these components to cool down
before changing a bulb. !
Make sure the bulbs are always securely
installed.
The bulbs and lamps are an essential compo-
nent of vehicle safety. You must therefore
make sure that these function correctly at all
times. Have the headlamp setting checked
regularly.
Observe the following notes when changing a
bulb:
R Always switch off the ignition before replac-
ing bulbs in the lighting system. This will
prevent a short circuit.
R Wear gloves and eye protection when
changing a bulb.
R Do not use a bulb that has been dropped or
that has scratches on its glass tube. The
bulb could may explode.
R A bulb could explode if:
- you touch it
- it is hot
- you drop it
- you scratch or score it
R Marks on the glass tube shorten the operat-
ing life of a bulb. Do not touch the glass
tube with your bare hands. If necessary,
clean the glass tube when cold with alcohol
or spirit. Then rub off the glass tube with a
clean, lint-free cloth.
R Make sure that bulbs are protected from
moisture when operating and that they do
not come into contact with liquids. Make
sure that seals are seated correctly and
replace damaged seals.
R Check the contacts for signs of corrosion
and clean these if required.
R Only operate bulbs in closed lamps which
have been designed for this purpose.
R Only use spare bulbs of the same type, with
the prescribed voltage and the correct wat-
tage.
R If the new bulb does not light up, consult a
qualified specialist workshop. Replacing bulbs

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

Vehicles with halogen headlamps
The headlamps do not need to be switched to
symmetrical low beam. The legal requirements
of countries in which traffic drives on the
opposite side of the road to the country where
the vehicle is registered are met without the
need to convert the headlamps. Transport by rail
Transporting your vehicle by rail may be sub-
ject to certain restrictions or require special
measures to be taken in some countries due
to varying tunnel heights and loading stand-
ards.
You can obtain information on this from any
Mercedes-Benz Commercial Van Center. Braking
Important safety notes 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.
Downhill gradients !
Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
This also applies to automatic braking if you
have activated cruise control.
On long and steep downhill gradients, you
should change down to shift range 2 or 1 in
good time
(Y page 133).
This should be observed in particular when
driving with a laden vehicle and when towing a
trailer.
You thereby make use of the braking effect of
the engine and do not have to brake as often
to maintain the speed. This relieves the load
on the service brake and prevents the brakes
from overheating and wearing too quickly. Heavy and light loads G
WARNING
If you rest your foot on the brake pedal
while driving, the braking system can over-
heat. This increases the stopping distance
and can even cause the braking system to
fail. There is a risk of an accident.
Never use the brake pedal as a footrest.
Never depress the brake pedal and the
accelerator pedal at the same time.
! Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
If the brakes have been subjected to a heavy
load, do not stop the vehicle immediately.
Drive on for a short while. The brakes are
cooled down more quickly in the airflow.
Wet road surfaces If you have been driving for a long time in
heavy rain without braking, there may be a
delayed response when you first apply the
brakes. This may also occur after driving
through a car wash or deep water.
You must depress the brake pedal more firmly.
Maintain a longer distance to the vehicle in
front.
While paying attention to the traffic conditions,
you should brake the vehicle firmly after driv-
ing on a wet road surface or through a car
wash. This heats the brake discs, so that they
dry more quickly, which protects them against
corrosion.
Limited braking performance on salt-
treated roads When driving on salted roads, salt may start to
build up on the brake disks and brake pads.
This can increase braking distances considera-
bly.
Maintain a greater distance to the vehicle in
front.
To remove any build-up of salt that may have
formed:
X Apply the brakes at the start of the journey,
occasionally during journey and at the end 142
Driving tips
Driving and parking

R
Drive with extreme care over unknown ter-
rain where you can only see for a short dis-
tance. As a precaution, get out of the vehi-
cle to take a look at the route to be taken in
advance.
R Check the water depth before fording.
R Watch out for obstacles (e.g. rocks, holes,
tree stumps and ruts).
R Avoid edges where the surface could crum-
ble or break away.
Checklist after driving off-road !
If you detect damage to the vehicle after
driving off-road, have the vehicle checked
immediately at a qualified specialist work-
shop.
Off-road driving places a higher demand on
your vehicle than normal road operation.
Check your vehicle after driving on rough ter-
rain. By doing so you will notice any damage in
good time and reduce the risk of an accident
for yourself and other road users. Clean your
vehicle thoroughly before driving on public
roads.
Observe the following points after driving off-
road, on construction sites and before driving
on public roads:
X Activate ESP ®
(Y page 69).
X Clean the headlamps and tail lamps and
check them for damage.
X Clean the front and rear license plates.
X Clean the windshield, windows and exterior
mirrors.
X Clean the steps, door sills and grab handles.
This increases safety of footing.
X Clean the wheels/tires, wheel housings and
the underbody of the vehicle with a water
jet.
This increases road grip, especially on wet
road surfaces.
X Check the wheels/tires and wheel housings
for trapped foreign objects and remove
them.
Trapped foreign objects can damage the
wheels/tires and may be flung out from the
vehicle when you continue driving.
X Check the underbody for trapped branches
or other parts of plants and remove them.
Trapped branches or other parts of plants
increase the risk of fire and can cause dam- age to fuel lines, brake hoses and the rubber
bellows of axle joints and drive shafts.
X Clean the brake disks, brake pads and axle
joints, particularly after operation in sand,
mud, grit/gravel, water or similarly dirty
conditions.
X Check the entire floor assembly, the tires,
wheels, bodywork structure, brakes, steer-
ing, chassis and exhaust system for any
damage.
X Check the service brake for operating
safety, e.g. carry out a brake test.
X If you notice strong vibrations after driving
off-road, check the wheels and drive train
for foreign objects again. Remove any for-
eign objects which can lead to imbalances
and thus cause vibrations. Driving in mountainous areas
When driving in mountainous areas, note that
the power output of the engine, and with it its
gradient climbing capability, decrease with
increasing altitude. Please take note of this
particularly when driving with a trailer in moun-
tainous areas.
The maximum permissible trailer loads are
valid for journeys at altitudes up to

1100 yds
(1000 m) above sea level with gradients up to
12%.
Information on maximum permissible trailer
loads can be found in your vehicle registration
papers and on the vehicle identification plate
(Y page 304) or under "Trailer loads" ( Y page 315).
When driving at altitudes of 2700 yds
(2500 m) above sea level, the ECO start/stop
function is no longer available.
Notes on braking on downhill gradients can be
found in the "Braking" section (Y page 142). Driving systems
