Steering Pilot cannot provide assistance:
R On very sharp corners
R When you are towing a trailer
R A loss of tyre pressure or a defective tyre has
been detected and displayed
Observe the important safety notes on Distance Pilot DISTRONIC (Y page 184).
The steering interventions are carried out with a
limited steering moment. The system requires
the driver to keep his hands on the steering
wheel and to steer himself.
If you do not steer yourself or if you take your
hands off the steering wheel for a prolonged
period of time, the system will first alert you with a visual warning. A steering wheel symbol
appears in the multifunction display. If you have
still not started to steer and have not taken hold
of the steering wheel after five seconds at the
latest, a warning tone also sounds to remind you to take control of the vehicle. Steering Pilot is
then switched to passive. Distance Pilot
DISTRONIC remains active.

Road Engineering package)
Important safety notes Level control adapts the vehicle level automati-
cally to the current operating and driving situa-
tion. This results in reduced fuel consumption
and improved handling.
Make changes to the vehicle level while the
vehicle is in motion. This enables the vehicle to adjust to the new level as quickly as possible.
The vehicle level may change visibly if you park
the vehicle and the outside temperature
changes. If the temperature drops, the vehicle
level lowers; with an increase in temperature,
the vehicle level rises.
If you unlock the vehicle or open a door, the
vehicle begins to compensate for load discrep-
ancies while still parked. However, for signifi-
cant level changes, e.g. after the vehicle has
been stationary for a long period, the engine
must be running. For safety reasons, the vehicle
is only lowered when the doors are closed. Low-
ering is interrupted if a door is opened; it con-
tinues once the door has been closed.

WARNING
People's limbs may become trapped if they
are located underneath the vehicle or
between the vehicle body and the tyres when the vehicle is lowering. There is a danger of
injury.
When lowering the vehicle, make sure no one
is underneath the vehicle or in the immediate vicinity of the wheel arches. G
WARNING
When driving at a raised vehicle level, the driv- ing characteristics may be significantly affec-ted by the vehicle's raised centre of gravity.
The vehicle may be more liable to tip when
cornering, for example. There is a risk of an
accident. 192

If this vehicle is not driven in a safe manner, it
can lead to an accident, to the vehicle over-
turning as well as serious or even fatal inju-
ries.
R In the event of an accident with the vehicle
overturning, passengers who are not wearing
their seat belt are considerably more likely to die than passengers wearing their seat belt.
You and all vehicle occupants should always
wear your seat belts.

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 your vehicle documents
R on the identification plates of the trailer tow
hitch and the trailer
R on the vehicle identification plate
If the values differ, the lowest value applies.
You will find the values approved by the manu-
facturer on the vehicle identification plates and
those for the towing vehicle under "Technical
data" (Y page 390).
When towing a trailer, your vehicle's handling
characteristics will be different in comparison to
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 can impair the vehicle's handling charac-
teristics. Adapt your driving style accordingly.
Maintain a safe distance. Drive carefully.
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 !
If you have a trailer tow hitch retrofitted,
changes to the engine cooling system may be necessary, depending on the vehicle type.
If you have a trailer tow hitch retrofitted,
observe the anchorage points on the chassis.
Check the tyre pressures when towing a trailer.
You will find the values in the tyre pressure table in the vehicle fuel filler flap (Y page 364).Please note that when towing a trailer, the fol-
lowing driving systems have limited availability
or are not available at all.

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 390).
Driving tips Observe the information on ESP
®
trailer stabili-
sation (Y page 74) and on pulling away with a
trailer (Y page 151).
Select the Comfortdrive program using the
DYNAMIC SELECT controller (Y page 155).
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
permissible speed is for your trailer. Observe the legally prescribed maximum speed in the rele-
vant 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 390). If you utilise any of the
added maximum rear axle load when towing a
trailer, the vehicle/trailer combination may not
exceed a maximum speed of 100 km/h for rea-
sons concerning the operating permit. This also
applies in countries in which the permissible
maximum speed for vehicle/trailer combina-
tions is above 100 km/h.
When towing a trailer, your vehicle's handling
characteristics will be different to when driving
without a trailer and the vehicle will consume
more fuel.
Use the left-hand gearshift paddle to shift to a
lower gear on long and steep downhill gradients.
This also applies if you have activated cruise
control, the speed limiter or Distance Pilot
DISTRONIC.
This will use the braking effect of the engine, so
less braking will be required to maintain the
vehicle speed. This relieves the load on the 234
