2017 MERCEDES-BENZ SPRINTER warning light

Lane Keeping Assist does not keep your vehicle
in its lane.
The system may be impaired or may not function
if:
Rif the vehicle is incorrectly loaded
(Ypage 208)
Rthere is poor visibility, e.g. due to insufficient
illumination of the road, or due to snow, rain,
fog or spray
Rthere is glare, e.g. from oncoming traffic, the
sun or reflection from other vehicles (e.g. if
the road surface is wet)
Rthe windshield is dirty, fogged up, damaged or
covered, for instance by a sticker, in the vicin-
ity of the camera
Rno, or several, unclear lane markings are pres-
ent for one lane, e.g. in a construction area
Rthe lane markings are worn away, dark or cov-
ered up, e.g. by dirt or snow
Rthe distance to the vehicle in front is too small
and the lane markings thus cannot be detec-
ted
Rthe lane markings change quickly, e.g. lanes
branch off, cross one another or merge
Rthe road is narrow and winding
Rthere are highly variable shade conditions on
the road
A warning may be given if a front wheel passes
over a lane marking. In addition, a warning tone
sounds and the Ãindicator lamp in the
instrument cluster flashes red.

Roll-back warning
PARKTRONIC automatically monitors the area
behind the vehicle if the vehicle begins to roll
backwards without reverse gear engaged, e.g.
after stopping on an uphill gradient.
If PARKTRONIC recognizes an obstacle at a dis-
tance of at most 31 in (80 cm), all the segments
in the warning displays light up. A continuous
warning tone also sounds as the vehicle
approaches the obstacle and for a further
2 seconds after the vehicle has come to a halt.
Activating/deactivating PARKTRONIC
XPress the fbutton.
If PARKTRONIC is deactivated, the indicator
lamp in the switch lights up.
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 connection
between 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.
Remove a detachable trailer coupling if it is no
longer required. PARKTRONIC measures the
minimum detection range to an obstacle from
the bumper, not the ball coupling.

Rear view camera
Important safety notes
The rear view camera is only an aid. It cannot
replace your own awareness of the immediate
surroundings. You are responsible for safe
maneuvering, parking and pulling away. When
maneuvering, parking and pulling away, make
sure that there are no persons, animals or
objects in the maneuvering area.
The rear view camera is a visual parking aid.
Information on operation can be found in the
separate Audio 15 supplement.
The camera is in the middle of the roof above the
high-mounted brake lamp (
Ypage 232).
You can find information on cleaning the camera
in the "Maintenance and care" section
(
Ypage 232).
Working mode
ADR (working speed governor)
General notes
When activated, ADR automatically increases
the engine speed to a preset speed or a speed
you have set.
iAfter a cold start, the idling speed of the
engine is increased automatically. If the pre-
set working speed is lower than the increased idling speed, the working speed is only
reached once the engine has completed the
warm-up phase.
It is only possible to activate ADR with the
vehicle stationary and the parking brake
applied.
The selector lever of the automatic transmis-
sion must be in position P.

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 use a ball coupling that is not approved
for your vehicle, it may cause excessive strain
on the trailer tow hitch. This can cause dam-
age to the vehicle and the trailer may come
loose during the journey. The handling may be
impaired and the rear axle may be overloaded.
This may lead to an accident involving serious
or even fatal injury.
Therefore note the following:
ROnly install a ball coupling that is approved for your vehicle.
RBefore the journey, make sure that the ballcoupling is correctly installed and secured.
To do this, observe the operating instruc-
tions of the ball coupling manufacturer.
RDo not make any modifications to the ball
coupling or the trailer tow hitch.
You must observe the operating instructions
of the trailer tow hitch or ball coupling manu-
facturer.
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.

Useful information
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 possi-
ble. Note that your vehicle may not be equipped
with all of the described functions. This also
applies to systems and functions relevant to
safety.
Read the information on qualified specialist
workshops (
Ypage 27).
Important safety notes
GWARNING
If you are driving and reach through the steer- ing wheel to operate the adjustment knob,
you could lose control of the vehicle. There is
a risk of an accident and injury.
Only operate the adjustment knobs when thevehicle is stationary. Do not reach through the
steering wheel when driving.
GWARNING
If you operate information systems and com-
munication equipment integrated in the vehi-
cle while driving, you will be distracted from
traffic conditions. You could also lose control
of the vehicle. There is a risk of an accident.
Only operate the equipment when the traffic
situation permits. If you are not sure that this
is possible, park the vehicle paying attention
to traffic conditions and operate the equip-
ment when the vehicle is stationary.
GWARNING
If the instrument cluster has failed or mal-
functioned, you may not recognize function
restrictions in systems relevant to safety. The
operating safety of your vehicle may be
impaired. There is a risk of an accident.
Drive on carefully. Have the vehicle checked
at a qualified specialist workshop immedi-
ately. You must observe the legal requirements for the
country in which you are currently driving when
operating the on-board computer.
The on-board computer display only shows mes-
sages and warnings from certain systems. You
should therefore make sure your vehicle is oper-
ating safely at all times. If the operating safety of
your vehicle is impaired, stop the vehicle as
soon as possible, paying attention to road and
traffic conditions. Then consult a qualified spe-
cialist workshop.
