When towing a trailer, your vehicle's handling
characteristics will be different in comparison
with when driving without a trailer.
The vehicle/trailer combination:
is heavier
R
is restricted in its acceleration and
R
gradient-climbing capability
has an increased braking distance
R
is affected more by strong crosswinds
R
demands more sensitive steering
R
has a larger turning radius
R
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.
General notes
Do not exceed the legally prescribed
R
maximum speed for vehicle/trailer
combinations in the relevant country.
This lowers the risk of an accident.
Only install an approved trailer coupling on

You will find installation dimensions and loads
in the "Technical data" section
( Y page 442).
The maximum noseweight of the trailer
drawbar on the ball coupling is 600 lbs
(272 kg).
However, the actual drawbar load must not
exceed the value given on the trailer tow hitch
or trailer identification plates. The lowest
weight applies.
Please note that when towing a trailer,
PARKTRONIC ( Y page 212) and Blind Spot
Assist ( Y page 234) are only available with
limitations, or not at all.

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
legally prescribed maximum speed in the
relevant country.
For certain Mercedes-Benz vehicles, the
maximum permissible rear axle load is
increased when towing a trailer. See
"Technical data" to find out whether this
applies to your vehicle (
utilize any of the added maximum rear axle
load when towing a trailer, the vehicle/trailer
combination may not exceed a maximum
speed of 60 mph (100 km/h) for reasons
concerning the operating permit. This also
applies in countries in which the permissible
maximum speed for vehicle/trailer
combinations is above 60 mph (100 km/h).
