system
If cruise control automatically deactivates, a
warning tone sounds and the Cruise Con‐
trol Off message appears briefly in the dis-
play.
The V symbol and the display of the stored
speed in the header or in the status area of
the display are then not shown.
Problems with cruise control The speed cannot be set when cruise control
is activated.
The display is showing a message of high pri-
ority and cannot therefore show a change in
speed.
X Proceed as instructed by the message in the
display. COLLISION PREVENTION ASSIST
General notes COLLISION PREVENTION ASSIST helps you:
R to minimize the risk of a front-end collision
with a detected obstacle in the path of your
vehicle
R to reduce the consequences of a collision
with the vehicle in front
The system uses radar sensors to detect vehi-
cles in front.
COLLISION PREVENTION ASSIST consists of
the distance warning function and Adaptive
Brake Assist.
If COLLISION PREVENTION ASSIST is malfunc-
tioning, the display shows a corresponding
message
(Y page 222). Distance warning function Important safety notes
G
WARNING
The distance warning function does not
react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R when cornering
The distance warning function may not give
warnings in all critical situations. There is a
risk of an accident.
Always pay careful attention to the traffic
situation and be ready to brake.
Always adapt your speed to suit the prevail-
ing road and traffic conditions. G
WARNING
The distance warning function cannot
always clearly identify objects and complex
traffic situations.
In such cases, the distance warning function
may:
R give an unnecessary warning
R not give a warning
There is a risk of an accident.
Always pay careful attention to the traffic
situation and do not rely solely on the dis-
tance warning function.
In particular, the detection of obstacles can be
impaired in the case of: R dirt on the sensors or anything else covering
the sensors
R snow or heavy rain
R interference from other radar sources
R strong radar reflections, for example, in
parking garages
R a narrow vehicle traveling in front, e.g. a
motorbike
R a vehicle traveling in front on a different line
Due to the nature of the system, particularly
complicated but non-critical driving conditions Driving systems

Ensure that the following weights are not
exceeded:
R the permissible noseweight
R the permissible trailer load
R the permissible rear axle load of the towing
vehicle
R the maximum permissible gross vehicle
weight of both the towing vehicle and the
trailer
R the maximum permissible gross weight of
vehicle/trailer combination
The applicable permissible values that may not
be exceeded can be found:
R in your vehicle documents
R on the type plates for the trailer tow hitch
R on the type plates for the trailer
R on the vehicle identification plate
(Y page
304)
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 "Tech-
nical data" section (Y page 315).
Your vehicle behaves differently with a trailer
than without one.
The vehicle/trailer combination:
R is heavier
R is restricted in its acceleration and gradient-
climbing capability
R has an increased braking distance
R is more susceptible to strong crosswinds
R requires more sensitive steering
R has a larger turning radius
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 distance.
If you require any further explanation regard-
ing the information contained in the Operating
Instructions, please contact a Mercedes-Benz
Commercial Van Center.
General notes R
Observe the legally permitted maximum
speed for vehicle/trailer combinations in
the relevant country, state or Canadian
province. Before beginning the journey,
check the trailer's documents for the maxi-
mum permitted speed of your trailer. This reduces the risk of accidents.
R Install 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.
R The trailer coupling is one of the most
important 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 instruc-
tions).
R The bumpers of your vehicle are not suitable
for installing detachable trailer couplings.
R Do not attach rented trailer tow hitches or
other detachable trailer tow hitches to the
bumper.
R Minimize the risk of damage to the ball cou-
pling. If you do not require the ball coupling,
remove it from the ball coupling recess.
You will find weight information under "Techni-
cal data"
(Y page 315).
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 per-
mitted speed of your trailer. Observe the
legally permitted maximum speed in the rele-
vant 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.
i This 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 Towing a trailer

See Operator's Man‐
ual Blind Spot Assist is temporarily inoperative. Possible causes:
R You have attached a trailer.
R The sensors in the rear bumper are dirty.
R The function is impaired due to heavy rain or snow.
R The radar sensor system is temporarily inoperative, e.g. due to
electromagnetic radiation emitted by nearby TV or radio stations
or other sources of electromagnetic radiation.
R The system is outside the operating temperature range.

conditions.
X Secure the vehicle to prevent it from rolling away ( Y page

N The yellow ABS warning lamp is lit while the engine is running.
ABS has been deactivated due to a malfunction. BAS, hill start assist and ESP
®
as well as its driving safety systems, for example, are therefore also deactiva-
ted.
ATTENTION ASSIST is deactivated and other driving systems could be automati-
cally deactivated.
G WARNING
The brake system continues to function normally, but without the functions lis-
ted above. The wheels could therefore lock prematurely if you brake hard, for
example.
This causes steerability and braking to be greatly impaired. The braking distance
may increase in emergency braking situations.
If ESP ®
is not operational, ESP ®
will not stabilize the vehicle.
There is an increased risk of skidding and accidents.
X Switch the engine off, wait briefly and start the engine again.
X Check if the display message has disappeared and ESP ®
is operational.
X If the display message continues to be displayed:
R Drive on with care.
R Visit a qualified specialist workshop immediately.
If the ABS control unit is faulty, there is also a possibility that other systems will
be restricted or unavailable. ÷
