cruise control MERCEDES-BENZ METRIS 2017 MY17 Operator’s Manual

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
Rthe maximum permissible gross vehicle
weight of both the towing vehicle and the
trailer
Rthe maximum permissible gross weight of
vehicle/trailer combination
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 303).
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 314).
Your vehicle behaves differently with a trailer
than without one.
The vehicle/trailer combination:
Ris heavier
Ris restricted in its acceleration and gradient-
climbing capab ility
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 distance.
If you 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.
You will find weight information under "Te
chni-
cal data" (Ypage 314).
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.

Solutions
ò!NThe 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 deactivated.
ATTENTION ASSIST is deactivated and other driving systems could be automati-
cally deactivated.
GWARNING
The brake system continues to function normally, but without the functions listed
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
can 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.
XSwitch the engine off, wait briefly and start the engine again.
XCheck if the display message has disappeared and ESP®is operational.
XIf the display message continues to be displayed:
RDrive on with care.
RVisit a qualified specialist workshop immediately.
If the ABS control unit is faulty, there is also a possibility that other systems, such
as the automatic transmission, will be restricted or unavailable.
÷N The yellow ESP®warning lamp flashes while the vehicle is in motion.
ESP®or traction control is intervening because there is a risk of skidding or at least
one wheel has started to spin.
Cruise control is automatically deactivated.
XWhen starting off, do not depress the accelerator pedal more than is necessary.
XEase off the accelerator pedal while driving.
XAdapt your driving style to suit the weather and road conditions.
XDo not deactivate ESP®.
In rare cases , it may be best to deactivate ESP®(Ypage 66).
