also switched on when a door is opened. This
means that slightly cooled air enters the vehi-
cle interior after the engine is started, to cool
the vehicle more rapidly.
Switching the residual heat function
on/off
General notes
Only vehicles with dual-zone automatic climate
control have the residual heat function.
Once the engine is switched off, it is possible to
make use of the residual heat of the engine to
continue heating or ventilating the front com-
partment of the vehicle for approximately
30 minutes. The heating or ventilation time
depends on the set interior temperature.

The air vents can only be adjusted on vehicles
with rear-compartment air conditioning.
Vehicles with rear-compartment air condition-
ing: in heating mode, the air in the rear com-
partment is automatically distributed in the foot-
wells and roof area after the coolant has
reached the required temperature. In cooling
mode, in the initial phase the air is distributed in
the footwells and roof area of the hot vehicle,
and subsequently only in the roof area.

Refueling
Important safety notes
GWARNING
Fuel is highly flammable. Improper handling of
fuel creates a risk of fire and explosion.
Avoid fire, open flames, smoking and creating
sparks under all circumstances. Switch off the
engine and, if applicable, the auxiliary heating
before refueling.
GWARNING
Fuel is poisonous and hazardous to health.
There is a risk of injury.
You must make sure that fuel does not come into contact with your skin, eyes or clothing
and that it is not swallowed. Do not inhale fuel
vapors. Keep fuel away from children.
If you or others come into contact with fuel,
observe the following:
RWash away fuel from skin immediately
using soap and water.
RIf fuel comes into contact with your eyes,
immediately rinse them thoroughly with
clean water. Seek medical assistance with-
out delay.
RIf fuel is swallowed, seek medical assis-
tance without delay. Do not induce vomit-
ing.
RImmediately change out of clothing which
has come into contact with fuel.
GWARNING
Electrostatic buildup can create sparks and
ignite fuel vapors. There is a risk of fire and
explosion.
Always touch the vehicle body before opening
the fuel filler flap or touching the fuel pump
nozzle. Any existing electrostatic buildup is
thereby discharged.
134Refueling
Driving and parking

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 permissible
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 replacement
parts may not always be immediately available.
The relevant workshop directories are available
from any Mercedes-Benz Commercial Van Cen-
ter.
Fuel
In some countries, only fuels with a higher sulfur
content are available.
Unsuitable fuel can cause engine damage. You
will find information about fuel under "Service
products and capacities" (
Ypage 307).
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.
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 oppo-
site 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 subject
to certain restrictions or require special meas- ures to be taken in some countries due to vary-
ing tunnel heights and loading standards.
You can obtain information on this from any
Mercedes-Benz Commercial Van Center.
Braking
Important safety notes
GWARNING
If you shift down on a slippery road surface in an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
There is an increased danger of skidding 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 2or1 in
good time (
Ypage 130).
This should be observed in particular when driv-
ing 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
GWARNING
If you rest your foot on the brake pedal while
driving, the braking system can overheat. 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.

The applicable permissible values that may not
be exceeded can be found:
Rin your vehicle documents
Ron the type plates for the trailer tow hitch
Ron the type plates for the trailer
Ron the vehicle identification plate
(Ypage 305)
Where the values differ, the lowest is valid.
You will find the values approved by the manu-
facturer on the vehicle identification plates and
those for the towing vehicle in the "Technical
data" section (
Ypage 316).
Your vehicle behaves differently with a trailer
than without one.
The vehicle/trailer combination:
Ris heavier
Ris restricted in its acceleration and gradient-
climbing capability
Rhas an increased braking distance
Ris more susceptible to strong crosswinds
Rrequires more sensitive steering
Rhas a larger turning circle
This may impair the handling characteristics.
When towing a trailer, always adjust your speed
to suit the road and weather conditions. Drive
carefully. Maintain a safe dista nce.
If y

ou require any further explanation regarding
the information contained in the Operating
Instructions, please contact a Mercedes-Benz
Commercial Van Center.
General notes
RObserve the legally permitted maximum
speed for vehicle/trailer combinations in the
relevant country, state or Canadian province.
Before beginning the journey, check the trail-
er's documents for the maximum permitted
speed of your trailer.
This reduces the risk of accidents.
RInstall only an approved trailer coupling on
your vehicle. Only use a ball coupling for your Metris trailer tow hitch if it has been approved
for your vehicle. More information on the
availability, mounting and installation of the trailer electrics is available at any qualified
specialist workshop.
RThe trailer coupling is one of the most impor-
tant vehicle parts with regard to road safety.
Observe the notes on operation, care and
maintenance of the trailer tow hitch (see the
manufacturer's operating instructions).
RThe bumpers of your vehicle are not suitable
for installing detachable trailer couplings.
RDo not attach rented trailer tow hitches or
other detachable trailer tow hitches to the
bumper.
RMinimize the risk of damage to the ball cou-
pling. If you do not require the ball coupling,
remove it from the ball coupling recess.
Yo u w
ill find weight information under "Techni-
cal data" (Ypage 316).
The height of the ball neck changes according to
the load on the vehicle. If this is case, use a
trailer with a height-adjustable trailer drawbar.
Driving tips
The maximum permissible speed for vehicle/
trailer combination depends on the type of
trailer. Before beginning the journey, check the
trailer's documents for the maximum permitted
speed of your trailer. Observe the legally per-
mitted maximum speed in the relevant country, state or Canadian province.
When towing a trailer, your vehicle's handling
characteristics will be different in comparison to
when driving without a trailer and it will con-
sume more fuel.
On long and steep downhill gradients, select a
lower gear.
iThis also applies if cruise control is activa-
ted.
This enables you to utilize the engine's braking
effect and you do not need to brake so heavily to keep the correct speed. This relieves the load on
the brake system and prevents the brakes from overheating and wearing too quickly. If you need
to brake additionally, to not depress the brake
pedal constantly, but periodically.
Observe the notes on ESP
®trailer stabilization
(Ypage 67).
