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

This Operator's Manual describes all models
as well as standard and optional equipment of
your vehicle that were available at the time of
going to print. Country-specific variations are

Important safety notes
Observe the recommended settings on the fol-
lowing pages. Otherwise, the windows could
fog up.
To prevent the windows from fogging up:
R only switch off climate control briefly
R only switch on air-recirculation mode briefly
R for vehicles with air-conditioning system or
dual-zone automatic climate control, switch
on the "Cooling with air dehumidification"
function
R for vehicles with dual-zone automatic cli-
mate control, switch on the windshield
defrosting function briefly, if required Climate control regulates the temperature and
the humidity in the vehicle interior and filters
undesirable substances from the air.
Climate control is only operational when the
engine is running. The system only functions
optimally when the side windows are closed.
Ventilate the vehicle for a brief period during
warm weather. In order to cool the vehicle
more rapidly, switch climate control to air-
recirculation mode briefly. This will speed up
the cooling process and the desired interior
temperature will be reached more quickly.
The integrated filter can filter out most parti-
cles of dust and completely filters out pollen.
In vehicles with dual-zone automatic climate
control, gaseous pollutants and odors will also
be reduced. A clogged filter reduces the air-
flow into the vehicle interior. For this reason,
you should always observe the interval for
replacing the filter, which is specified in the
Maintenance Booklet. As the interval between
changes depends on environmental condi-
tions, e.g. heavy air pollution, the interval may
be shorter than stated in the Maintenance
Booklet. 114

Important safety notes
In certain driving and driving safety systems,
the sensors adjust automatically while a cer-
tain distance is being driven after the vehicle
has been delivered or after repairs. Full system
effectiveness is not reached until the end of
this teach-in procedure.
New or replaced brake pads and brake discs
only reach their optimal braking effect after a
few hundred kilometers of driving. Until then,
compensate for this by applying greater force
to the brake pedal. The first 1000 miles (1500 km)
For the service life and economy of your vehi-
cle it is crucial that you break in the engine
with due care.
R Therefore, protect the engine for the first
1000 miles (1500 km
) by driving at varying
vehicle and engine speeds.
R Avoid overstraining the vehicle and high
engine speeds during this period, e.g. driv-
ing at full throttle. Do not exceed Ø of the
permissible maximum speed for each gear.
R Do not change down a gear manually in
order to brake.
R Try to avoid depressing the accelerator
pedal beyond the pressure point (kickdown).
After 1000 miles (1500 km), you can increase
the engine speed gradually and accelerate the
vehicle to full speed.
i You should also observe these notes on
breaking-in if the engine or parts of the drive
train on your vehicle have been replaced. Driving
Important safety notes

WARNING
Flammable materials introduced through
environmental influence or by animals can
ignite if in contact with the exhaust system
or parts of the engine that heat up. There is
a risk of fire.
Carry out regular checks to make sure that
there are no flammable foreign materials in
the engine compartment or in the exhaust
system. G
WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could
affect, for example, the power steering and
the brake boosting effect. You will require
considerably more effort to steer and brake.
There is a risk of an accident.
Do not switch off the ignition while driving. G
WARNING
If the parking brake has not been fully
released when driving, the parking brake
can:
R overheat and cause a fire
R lose its hold function.
There is a risk of fire and an accident.
Release the parking brake fully before driv-
ing off.
! Warm up the engine quickly. Do not use
the engine's full performance until it has
reached operating temperature.
Only shift the automatic transmission to the
desired drive position when the vehicle is
stationary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery roads.
You could otherwise damage the drive train. 126

Shift ranges
:
To shift down and restrict the shift range
; To shift up and derestrict the shift range
In transmission position h and drive pro-
grams E and C, you can use the steering wheel
paddle shifters to change gear yourself and
restrict or derestrict the shift range of the
automatic transmission.
X To shift down and restrict the shift
range:
briefly pull left steering wheel paddle
shifter :.
The automatic transmission shifts to the
next gear down, depending on the gear cur-
rently engaged. The shift range is also
restricted.
The transmission position indicator also
shows the set shift range, e.g. D2. The auto-
matic transmission shifts only as far as the
relevant gear.
or X Pull and hold left steering wheel paddle
shifter :.
The automatic transmission will shift to a
range which allows easy acceleration and
deceleration. To do this, the automatic
transmission shifts down one or more gears
and restricts the shift range.
The transmission position indicator also
shows the set shift range, e.g. D2. The auto-
matic transmission shifts only as far as the
relevant gear.
The automatic transmission does not shift
down if you pull the left steering wheel pad-
dle shifter whilst traveling at too high a
speed. If the maximum engine speed for the
restricted shift range is reached and you
continue to depress the accelerator pedal,
the automatic transmission will shift up
automatically. This protects the engine from
overrevving. X
To shift up and extend the shift range:
briefly pull right steering wheel paddle
shifter
;.
The automatic transmission shifts to the
next gear up, depending on the gear cur-
rently engaged. This derestricts the shift
range at the same time.
If the display shows only transmission posi-
tion h, the shift range restriction is can-
celed.
X To derestrict the shift range: pull and hold
right steering wheel paddle shifter ;.
The automatic transmission shifts up one or
more gears depending on the gear currently
engaged. At the same time, the shift range
restriction is canceled and the display
shows transmission position D .
Shift ranges and driving situations =

Drive programs
General notes You can use the program selector button to
choose between different drive programs for
the automatic transmission, depending on the
engine. Engine management and the gearshift-
ing characteristics of the automatic transmis-
sion change depending on which drive pro-
gram is selected. Thus, a more comfort-orien-
ted, a more economical, or a sportier driving
style is supported, depending on the wish of
the driver. Selecting drive program M deacti-
vates automatic gearshifting, requiring that
you change gear manually.
After the engine is started, the automatic
transmission automatically switches to drive
program C (Comfort) for a comfortable and
economical driving style. Automatic transmission

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
