Mercedes-Benz GLC, Operator'S Manual

Page: 217 / 390

For more information, please contact a qualified
specialist workshop.
Please observe the manufacturer's operating
instructions for the trailer coupling if a detach-
able trailer coupling is used.
Couple and uncouple the trailer carefully. If you
do not couple the trailer to the towing vehicle
correctly, the trailer could become detached.
Make sure that the following values are not
exceeded:
R
the permissible trailer drawbar 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
The applicable permissible values, which must
not be exceeded, can be found:
R
in the vehicle documents
R
on the type plate for the trailer
R
on the vehicle identification plate
If the values differ, the lowest value applies.
When towing a trailer, your vehicle's handling
characteristics will be different in comparison
with when driving without a trailer.
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 affected more by strong crosswinds
R
demands more sensitive steering
R
has a larger turning circle
This could impair the handling characteristics.
When towing a trailer, always adjust your speed
to the current road and weather conditions. Do
not exceed the maximum permissible speed for
your vehicle/trailer combination.
Notes on towing a trailer
General notes
R
Do not exceed the maximum permissible
speed for vehicle/trailer combinations in the
relevant country.
This lowers the risk of an accident.
R
Only install an approved trailer coupling on
your vehicle.
Further information on availability and on
installation is available from any authorized
Mercedes-Benz Center.
R
The bumpers of your vehicle are not suitable
for installing detachable trailer couplings.
R
Do not install hired trailer couplings or other
detachable trailer couplings on the bumpers
of your vehicle.
R
If you no longer need the ball coupling,
remove it from the ball coupling recess. This
will reduce the risk of damage to the ball cou-
pling.
When towing a trailer, set the tire pressure on
the rear axle of the towing vehicle for a maxi-
mum load; see the tire pressure table in the fuel
filler flap (
Y
page 367).
Please note that when towing a trailer, the fol-
lowing driving systems have limited availability
or are not available at all:
R
PARKTRONIC (
Y
page 191)
R
Blind Spot Assist (
Y
page 205)
R
Active Lane Keeping Assist (
Y
page 212)
On vehicles without level control, the height of
the ball coupling will alter according to the load
placed on the vehicle. If necessary, use a trailer
with a height-adjustable drawbar.
You will find permissible trailer loads under
"Technical data" (
Y
page 384).
Driving tips
Observe the information on ESP
®
trailer stabili-
zation (
Y
page 72) and on pulling away with a
trailer (
Y
page 140).
The maximum permissible speed for vehicle/
trailer combinations depends on the type of
trailer. Before beginning the journey, check the
trailer's documents to see what the maximum
permitted speed is. Observe the maximum per-
missible speed in the relevant country.
For certain Mercedes-Benz vehicles, the maxi-
mum permissible rear axle load is increased
when towing a trailer. See the "Technical data"
section to find out whether this applies to your
vehicle (
Y
page 384). In the event of increased
rear axle load, the vehicle/trailer combination
may not exceed a maximum speed of 60 mph
(100 km/h) for reasons concerning the operat-
ing permit. This also applies in countries in
