You can obtain further information about the
correct child restraint system from any
Mercedes-Benz Commercial Van Center.
GWARNING
If the child restraint system is installed incor-
rectly on a suitable seat, it cannot protect as
intended. The child cannot then be restrained
in the event of an accident, heavy braking or
sudden changes of direction. There is an
increased risk of injury, possibly even fatal.
Make sure that you observe the child restraint
system manufacturer's installation instruc-
tions and the notes on use. Please ensure,
that the base of the child restraint system is
always resting completely on the seat cush-
ion. Never place objects, e.g. cushions, under or behind the child restraint system. Only use
child restraint systems with the original cover
designed for them. Only replace damaged
covers with genuine covers.
GWARNING
If a rearward facing child restraint system is
installed in the direction of travel by mistake, it cannot protect as intended. This is the case
if, for instance, you install a rearward-facing
child restraint system on a rear seat opposite
to the direction of travel. In the event of an
accident, a child might not be restrained cor-
rectly. This poses an increased risk of injury or
even fatal injury.
Always install the rear seat in the direction of
travel before you install the rearward facing
child restraint system.
GWARNING
If the child restraint system is installed incor-
rectly or is not secured, it can come loose in
the event of an accident, heavy braking or a
sudden change in direction. The child
restraint system could be thrown about, strik-
ing vehicle occupants. There is an increased
risk of injury, possibly even fatal.
Always install child restraint systems prop-
erly, even if they are not being used. Make
sure that you observe the child restraint sys-
tem manufacturer's installation instructions.
You will find further information on stowing
objects, luggage or loads under "Loading guide-
lines" (
Ypage 244).
GWARNING
Child restraint systems or their securing sys-
tems which have been damaged or subjected
to a load in an accident can no longer protect
as intended. The child cannot then be
restrained in the event of an accident, heavy
braking or sudden changes of direction. There is an increased risk of injury, possibly even
fatal.
Replace child restraint systems which have
been damaged or subjected to a load in an
accident as soon as possible. Have the secur-
ing systems on the child restraint system
checked at a qualified specialist workshop,
before you install a child restraint system
again.
The securing systems of child restraint systems
are:
Rthe seat belt system
Rthe LATCH-type (ISOFIX) securing rings
Rthe Top Tether anchorages
If it is absolutely necessary to carry a child on
the front-passenger seat, be sure to observe the
information on the "Occupant Classification
System (OCS)" (
Ypage 52). There you will also
find information on deactivating the front-
passenger front air bag.
All child restraint systems must meet the fol-
lowing standards:
RU.S. Federal Motor Vehicle Safety Standards
213 and 225
RCanadian Motor Vehicle Safety Standards
213 and 210.2
Confirmation that the child restraint system cor-
responds to the standards can be found on an
instruction label on the child restraint system.
This confirmation can also be found in the instal-
lation instructions that are included with the
child restraint system.
Observe the warning labels in the vehicle inte-
rior and on the child restraint system.

Safety

ProblemPossible causes/consequences andMSolutions
The engine does not
start.
The starter motor cannot
be heard.The battery is discharged or faulty.
XCheck the battery for damage.
XCharge the battery (Ypage 264).
The engine is not running
smoothly and is misfir-
ing.There is a malfunction in the engine electronics or a mechanical com-
ponent of the engine management system.
XOnly depress the accelerator pedal slightly.
Unburnt fuel may otherwise get into the catalytic converter and
damage it.
XHave the cause rectified immediately at a qualified specialist work-
shop.
Automatic transmission
Important safety notes
GWARNING
If the engine speed is above the idling speed
and you engage transmission position Dor R,
the vehicle could pull away suddenly. There is
a risk of an accident.
When engaging transmission position Dor R,
always firmly depress the brake pedal and do not simultaneously accelerate.
GWARNING
The automatic transmission switches to neu-
tral position Nwhen you switch off the engine.
The vehicle may roll away. There is a risk of an
accident.
Before switching off the engine, always switch
to parking position P. Prevent the parked vehi-
cle from rolling away by applying the parking
brake.
!If the engine is switched off, rolling in neutral
N can damage the power transmission and
result in transmission damage.
Always observe the instructions and safety
notes under "Tow starting and towing away"
(
Ypage 276).
Bear in mind that power transmission between
the engine and the transmission is interrupted
when the engine is switched off. For this reason,
shift the automatic transmission to Pbefore the engine is switched off and with the vehicle is
stationary. Apply the parking brake to prevent
the vehicle from rolling away.

RIncreased sensitivity. This improves driving
stability on slippery road surfaces, for exam-
ple.
RThe automatic transmission shifts up sooner.
The vehicle thus maintains lower engine
speeds.
Drive program E
Drive programEcohas the following character-
istics:
RThe vehicle exhibits particularly economical
handling characteristics.
RThe maximum available engine torque is
reduced.
ROptimal fuel consumption resulting from the
automatic transmission shifting down signifi-
cantly later and up significantly sooner, even
at full-load operation.
No shift point adjustment for adapting to indi-
vidual, dynamic driving styles.
In kickdown, the automatic transmission
automatically shifts to drive program C.
RIncreased sensitivity. This improves driving
stability on slippery road surfaces, for exam-
ple.
Driving tips
Accelerator pedal position
Your style of driving influences how the auto-
matic transmission shifts gear:
Rlittle throttle: early upshifts
Rlots of throttle: later upshifts
Kickdown
Use kickdown for maximum acceleration:
XDepress the accelerator pedal beyond the
pressure point.
The automatic transmission shifts to the next
gear down, depending on the engine speed.
XEase off on the accelerator pedal once the
desired speed is reached.
The automatic transmission shifts up again.
Rocking the vehicle free
At speeds up to 5 mph (9 km/h) you can switch
back and forth between drive position Dand
reverse gear Rwithout applying the brakes. This
helps when rocking the vehicle out of snow or
slush.
XPush the DIRECT SELECT lever alternately up
and down beyond the first point of resistance.
Towing a trailer
XDepending on the downhill gradient, limit the
shift range (Ypage 130) or shift manually into
a lower gear (Ypage 132) in which the engine
will operate in the middle of the engine speed
range. This also applies if cruise control is
activated.
Manual gearshifting
General notes
If you select drive program M, automatic gear-
shifting is deactivated and manual gearshifting
is automatically activated. You must then per-
manently change gear yourself for as long as the
drive program is selected.
Permanent manual gearshifting is deactivated
automatically when you switch from drive pro-
gram Mto another drive program. The auto-
matic transmission then shifts gears automati-
cally. The display shows the selected drive pro-
gram and transmission position Dagain.

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.

Warning display
Blind Spot Assist is not active at speeds below
approximately 20 mph (30 km/h). Vehicles in
the monitoring range are then not indicated.
If a vehicle is detected within the monitoring
range of Blind Spot Assist at speeds above
approximately 20 mph (30 km/h), warning
lamp:lights up red in the exterior mirror on
the corresponding side. Warning lamp :
always lights up when a vehicle enters the blind
spot monitoring range from behind or from the
side. When you overtake a vehicle, the warning
only occurs if the difference in speed is less than
7 mph (11 km/h).
If you select reverse gear, Blind Spot Assist is
inactive.
The intensity of warning lamps :depends on
the brightness of the ambient light and is con-
trolled automatically.
Collision warning
If a vehicle is detected in the monitoring range of
Blind Spot Assist and you switch on the corre-
sponding turn signal, a double warning tone
sounds once. The warning lamp in the corre-
sponding exterior mirror flashes. If the turn sig-
nal remains on, detected vehicles are indicated
by the flashing of the warning lamp in the exte-
rior mirror. There are no further warning tones.
Activating Blind Spot Assist

Lane Keeping Assist
General notes
Lane Keeping Assist monitors the area in front of
your vehicle by means of camera :which is
mounted at the top of the windshield. Lane
Keeping Assist detects lane markings on the
road and can warn you before you leave your
lane unintentionally.
This function is available in the range between
40 mph (60 km/h) and 125 mph (200 km/h).
A warning may be given if a front wheel touches a lane marking. It will warn you by means of

Towing a trailer
PARKTRONIC detects a coupled trailer if your
vehicle is equipped with the corresponding elec-
trical installations for trailer towing.
PARKTRONIC is deactivated for the rear area
when you establish an electrical connectionbetween your vehicle and a trailer. If you use an
adapter for the socket, remove it from the
socket after detaching the trailer. Otherwise,
PARKTRONIC remains deactivated for the rear
area.

Active Parking Assist
General notes
Active Parking Assist is an electronic parking
aid. The system uses ultrasound sensors to
measure the road on both sides of the vehicle
and indicates suitable parking spaces. It can
then actively steer and brake the vehicle to help
you to park and exit the parking space.
Active Parking Assist includes the PARKTRONIC
parking aid which indicates visually and audibly the distance between your vehicle and an
obstruction. To do this, PARKTRONIC uses the ultrasonic sensors of the Active Parking Assist
(
Ypage 153).
Important safety notes
Active Parking Assist is only an aid. It is not a
substitute for your attention to the immediate
surroundings. You are responsible for safe
maneuvering, parking and pulling away. Make
sure that no persons, animals or objects are in
the maneuvering range.
When you deactivate PARKTRONIC, Active Park-
ing Assist will also be deactivated.

Towing a trailer
Notes on trailer towing
Important safety notes
GWARNING
Installing an unsuitable ball coupling may
result in overloading of the trailer tow hitch
and the rear axle. This applies especially if the ball coupling in question is longer or angled
differently. This could seriously impair the
driving characteristics and the trailer can
come loose. There is a risk of an accident.
You should only ever install a ball coupling
that has the permissible dimensions and that
is designed to meet your trailer-towing
requirements. Do not modify the ball coupling
or the trailer tow hitch.
GWARNING
If you install a ball coupling other than the one
delivered with the vehicle, the trailer tow hitch
and the rear axle may be overloaded. This
applies especially if the ball coupling in ques-
tion is longer or angled differently. This could
seriously impair the driving characteristics
and the trailer can come loose. There is a risk
of an accident.
Only install the ball coupling delivered with
the vehicle or a ball coupling that is designed
to meet your trailer towing requirements. Do
not modify the ball coupling or the trailer tow
hitch.
GWARNING
If the ball coupling is not correctly installed
and secured, it could come loose while driving and endanger other road users. There is a risk
of an accident and injury.
Install and secure the ball coupling as descri-
bed in the ball coupling manufacturer's instal-
lation instructions. Make sure that the ball
coupling is correctly installed and secured
before every journey.
GWARNING
When the vehicle/trailer combination begins
to lurch, you could lose control of it. The vehi- cle/trailer combination could even rollover.
There is a risk of an accident.
On no account should you attempt to
straighten up the vehicle/trailer combination
by increasing the speed. Reduce vehicle
speed and do not countersteer. Apply the
brake as necessary.
You can attach carrier systems such as bicycle
racks or load-bearing implements on the ball
coupling. The maximum load-bearing capacity
of 165 lb (75 kg) applies when using carrier sys-
tems on the ball coupling.
Always observe the operating instructions pro-
vided by the manufacturers of the trailer cou-
pling and the ball coupling.
Couple and decouple the trailer carefully. When
backing up the towing vehicle, make sure
nobody is standing between the vehicle and the trailer.
A trailer which is incorrectly coupled to the tow-
ing vehicle could break away. A correctly cou-
pled trailer must be positioned horizontally
behind the towing vehicle.
Ensure that the following weights are not excee-
ded:
Rthe permissible noseweight
Rthe permissible trailer load
Rthe permissible rear axle load of the towing
vehicle
