puter, select the Lane Keeping Assist:
function (Ypage 185).
XSelectStandardorAdaptive.
In the setting Standard
, no warning vibration
occurs if:
Ryou operate the turn signal in the correspond-
ing direction. In this event, the warnings are
suppressed for a certain period of time.
Ra driving safety system, such as ABS, BAS or
ESP®, intervenes or performs a control
action.
When Adaptive

warning vibration when:
Ryou accelerate hard, e.g. kickdown.
Rbrake sharply.
Ryou steer actively, e.g. swerve to avoid an
obstacle or change lanes quickly.
Ryou cut the corner on a sharp bend.
In order that you are warned only when neces-
sary and in good time if you cross the lane mark-
ing, the system differentiates between various
conditions and warns you accordingly.
The warning vibration occurs earlier if:
Ryou approach the outer lane marking on a
bend.
Rthe road has very wide lanes, such as a high-
way.
Rthe system detects solid lane markings.
The warning vibration occurs later if:
Rthe road has narrow lanes.

Alertness Assistant ATTENTION
ASSIST
General notes
ATTENTION ASSIST helps you during long,
monotonous journeys such as on freeways and
interstate highways. It is active in the 40 mph
(60 km/h) to 125 mph (200 km/h) range. If
ATTENTION ASSIST detects typical indicators of fatigue or increasing lapses in concentration on
the part of the driver, it suggests taking a break.
Important safety notes
ATTENTION ASSIST is only an aid. The system
may not always detect fatigue or lapses in con-
centration until too late, or may not detect them
at all. ATTENTION ASSIST is not a substitute for
a well-rested and attentive driver.
The functionality of ATTENTION ASSIST is
restricted, and warnings may be delayed or not
occur at all:
Rif the length of the journey is less than approx-
imately 30 minutes
Rif the road condition is poor, e.g. if the surface
is uneven or if there are potholes
Rif there is a strong side wind
Rif you have adopted a sporty driving style with
high cornering speeds or high rates of accel-
eration
Rif you are predominantly driving at a speed
below 40 mph (60 km/h) or above 125 mph
(200 km/h)
Rif the time has been set incorrectly
Rin active driving situations, such as when you
change lanes or change your speed
ATTENTION ASSIST is reset and starts assessing
your attention again when you continue your
journey if:
Ryou switch off the engine
Ryou take off your seat belt and open the driv-
er's door, e.g. for a change of drivers or to
take a break
Displaying the attention level
For vehicles with steering wheel buttons you can
have the current ATTENTION ASSIST (Attention
Level) assessment displayed.
150Driving systems
Driving and parking

XSelectStatus Overviewin theAssist.menu and display the attention level
(Ypage 184).
The following information is displayed:
Rthe length of the journey since the last break.
Rthe attention level determined by ATTENTION
ASSIST, displayed in a bar display in five levels
from low to high.
Rif ATTENTION ASSIST is unable to calculate
the attention level and cannot output a warn-
ing, the System
Passivemessage appears in
the display. The bar display is then dimmed.
This is the case, for example, if you are pre-
dominantly driving at a speed below 40 mph
(60 km/h) or above 125 mph (200 km/h).
Activating ATTENTION ASSIST
XActivating ATTENTION ASSIST with the on-
board computer:
Ron vehicles without steering wheel buttons
(Ypage 175)
Ron vehicles with steering wheel buttons
(Ypage 185)
For vehicles with steering wheel buttons, the
system determines the attention level of the
driver depending on the setting selected:
Standard: the sensitivity with which the sys-
tem determines the attention level is set to
normal.
Sensitive: the sensitivity is set higher. The
driver is warned earlier.
When ATTENTION ASSIST is switched on and
the vehicle engine is running:
Ron vehicles without steering wheel buttons,
the À indicator lamp in the instrument
cluster lights up
Ron vehicles with steering-wheel buttons, the
display shows the Àsymbol:
-in the status area
-in the Status Overviewof the Assist.menu (Ypage 184)
For vehicles with steering wheel buttons, if you
deactivate ATTENTION ASSIST, the system is
automatically re-activated when you start the
engine. The system sensitivity then corresponds
to the last selection activated – standard or sen-
sitive.
If you switch off ATTENTION ASSIST in a vehicle without steering wheel buttons, the system
remains switched off even after you start the engine. The status of the system after switching
on the engine always corresponds to the status
last selected.
Warning in the display
If the system detects tiredness or increasing
lapses in concentration, the warning
Atten‐
tion Assist: Take a Break!orAttent.Asst: Take Break!is shown in the display.
An additional warning tone sounds.
XIf necessary, take a break.
XConfirm the message by pressing the a
button on the steering wheel.
On long journeys, take regular breaks in good
time to allow yourself to rest. If you do not take
a break and ATTENTION ASSIST continues to
detect increasing lapses in concentration, you
will be warned again after 15 minutes at the
earliest. This will only happen if ATTEN-
TION ASSIST still detects typical indicators of
fatigue or increasing lapses in concentration.
PARKTRONIC
General notes
PARKTRONIC is an electronic parking aid. The
system is equipped with ultrasonic sensors in
the front and rear bumpers to monitor the area
around your vehicle. PARKTRONIC indicates vis-
ually and audibly the distance between your
vehicle and an object.
Your vehicle features two separate sound emit- ters with different frequencies for the warning
tones. The warning ranges in front of and behind
the vehicle are indicated by different warning
tones.
PARKTRONIC is activated automatically when
you:
Rturn the key to position 2in the ignition lock
Rrelease the parking brake and
Rmove the selector lever to position D,N or R
PARKTRONIC is deactivated at speeds above
11 mph (18 km/h). PARKTRONIC is reactivated
at speeds below 10 mph (16 km/h).
Important safety notes
PARKTRONIC is only an aid. It cannot replace
your own awareness of the immediate surround-
ings. You are responsible for safe maneuvering,

Driving and parking
Z

For vehicles with a trailer coupling installed, the
minimum length for parking spaces will be
slightly increased.
If you have attached a trailer to your vehicle, you
should not use Active Parking Assist. Once the
electrical connection is established between
your vehicle and the trailer, Active Parking
Assist is no longer available. PARKTRONIC is
then deactivated for the rear area.
GWARNING
While parking or pulling out of a parking
space, the vehicle swings out and can drive
onto areas of the oncoming lane. This could
result in a collision with another road user.
There is a risk of an accident.
Pay attention to other road users. Stop the
vehicle if necessary or cancel the Active Park- ing Assist parking procedure.
!If unavoidable, you should drive over obsta-
cles such as curbs slowly and not at a sharp
angle. Otherwise, you may damage the
wheels or tires.
Active Parking Assist may also display spaces
not suitable for parking, e.g.:
Rin a zone where parking or stopping is pro-
hibited
Rin front of driveways or entrances and exits
Ron unsuitable surfaces
Parking tips:
Ron narrow roads, drive as closely as possible
past the parking space.
Rparking spaces that are littered or overgrown
might be identified or measured incorrectly.
Rparking spaces that are partially occupied by
trailer drawbars might not be identified as
such or be measured incorrectly.
Rsnowfall or heavy rain may lead to a parking
space being measured inaccurately.
Rwhen transporting a load which protrudes
from your vehicle, you should not use Active
Parking Assist.
Rnever use Active Parking Assist when snow
chains are installed.
Ralways ensure that the tire pressure is cor-
rect. This has a direct influence on the parking
characteristics of the vehicle.
Rif you mount w heels with a different wheel
size, this will have a direct influence on the
parking result.
Rif you mount tires from another manufacturer,
this may have an influence on the parking
result.
Rif you drive slowly past the parking space, a
better parking result is achieved.
Rpay attention to the PARKTRONIC warning
messages (Ypage 153) during the parking
procedure.
Ryou can intervene in the steering procedure to
correct it at any time. Parking assistance will
then be canceled and Active Parking Assist
stopped.
Use Active Parking Assist for parking spaces
that are:
Rparallel or at right angles to the direction of
travel.
Ron straight roads, not bends.
Ron the same level as the road, e.g. not on the
pavement.
Detecting parking spaces
GWARNING
If there are objects above the detection range:
RActive Park Assist may steer too early
Rthe vehicle may not stop in front of these
objects
You may cause a collision as a result. There is
a risk of an accident.
If objects are located above the detection
range, stop and deactivate Active Parking
Assist.
Objects located above the height range of Active
Parking Assist will not be detected when the
parking space is measured. These are not taken
into account when the parking procedure is cal-
culated, e.g. overhanging loads, overhangs or
truck loading ramps.
For further information on the detection range
(
Ypage 152).

Active Parking Assist does not assist you park-
ing in spaces at right angles to the direction of
travel if:
Rtwo parking spaces are located directly next
to one another
Rthe parking space is directly next to a low
obstacle such as a low curb
Ryou forward park
Active Parking Assist does not assist you park-
ing in spaces that are parallel or at right angles
to the direction of travel if:
Rthe parking space is on a curb
Rthe system reads the parking space as being
blocked, for example by foliage or grass pav-
ing blocks
Rthe area is too small for the vehicle to maneu-
ver into
Rthe parking space is bordered by an obstacle,
e.g. a tree, a post or a trailer
:Detected parking space on the left
;Parking symbol
=Detected parking space on the right
If the driver's seat belt is fastened and all doors
are closed, Active Parking Assist is activated
automatically when driving forwards. The sys-
tem is operational at speeds of up to approx-
imately 22 mph (35 km/h). While in operation,
the system independently locates and meas-
ures parking spaces on both sides of the vehicle.
Active Parking Assist will only detect parking
spaces:
Rparallel or at right angles to the direction of
travel
Rthat are parallel to the direction of travel and are at least 59 in (1.5 m) wide
Rthat are parallel to the direction of travel and
at least 40 in (1.0 m) longer than your vehicle
Rthat are at right angles to the direction of
travel and at least 40 in (1.0 m) widerthan
your vehicle
iNote that Active Parking Assist cannot
measure the length of a parking space if it is at right angles to the direction of travel. You will
need to judge whether your vehicle will fit in
the parking space.
When the vehicle is driving at speeds of up to
approximately 20 mph (30 km/h), parking sym-
bol ;is shown as a status display in the header.
The syste m d
etects and differentiates between
parking spaces which are parallel or at right
angles to the direction of travel. When a parking
space is detected, an arrow appears next to
parking symbol ;to indicate which side the
parking space is on. The parking space is dis-
played while you are driving past it and until you
are approximately 50 ft (15 m) away from it.
Active Parking Assist displays parking spaces on
the passenger side as standard. The parking
spaces on the driver's side are only displayed if
you operate the turn signal on the driver's side.
When parking on the driver's side, you must
operate the turn signal until you have started
active parking assistance by pressing the a
button on the steering wheel.
Parking
GWARNING
If you leave the driver's seat when the vehicle is only being braked by Active Parking Assist,
the vehicle could roll away if:
Rthere is a malfunction in the system or in
the voltage supply.
Rthe electrical system in the engine com-
partment, the battery or the fuses are tam-
pered with.
Rthe battery is disconnected.
Rthe vehicle is accelerated, e.g. by a vehicle
occupant.
There is a risk of an accident.
Before leaving the driver's seat, always secure the vehicle against rolling away.
If PARKTRONIC detects obstacles, Active Park-
ing Assist brakes automatically during the park- ing process. You are responsible for braking in
good time.
156Driving system s
Driving an d parking

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 needto brake additionally, to not depress the brake
pedal constantly, but periodically.
Observe the notes on ESP
®trailer stabilization
(Ypage 67).
Driving tips
If the trailer begins to swing from side to side:
XDo not accelerate.
XDo not counter-steer.
XBrake if necessary.
iYou can reduce the risk of the trailer swing-
ing and rocking by retrofitting anti-roll bars or trailer stability programs. Further information
is available at your authorized Mercedes-Benz
Van Dealer.
RMaintain a greater distance than you would
when driving without towing a trailer.
RAvoid sudden braking. Apply the brakes gen-
tly at first to allow the trailer brake to overrun.
Then, increase the brake force quickly.
RThe figures for the gradient climbing capabil-
ities from a standstill refer to sea level. When
driving in mountainous areas, note that the
power output of the engine, and with it its
gradient climbing capability, decrease with
increasing altitude.
Coupling up a trailer
Trailer coupled ready for use
XMake sure that the selector lever of the auto-
matic transmission is in position P.
XOn vehicles with an automatic transmission,
ensure that the transmission is in position P.
XEngage the vehicle's parking brake.
XClose all doors.
XPosition the trailer horizontally behind your
vehicle.
iThe height of the ball neck changes accord-
ing to the load on the vehicle. In this case, use
a trailer with a height-adjustable trailer draw-
bar.
XCouple the trailer.
XEstablish all electrical and other connections to the trailer. When doing so, hook the break-
away cable of the trailer into the eyelet on the
ball coupling.
XRemove the objects that are preventing the
trailer from rolling, e.g. wheel chocks.
XRelease the trailer parking brake.
iThe subharness of the vehicle has a cable
connection to the brake lamp indicator lamp.
Observe the maximum permissible trailer
dimensions (width and length).
Most federal states and all Canadian provinces
require by law:
Rsafety chains between the towing vehicle and the trailer. The chains should be cross-wound
under the trailer drawbar. They must be fas-
