ATTENTION ASSIST
General notes ATTENTION ASSIST helps you during long,
monotonous journeys such as on motorways
and trunk roads. It is active in the 60 km/h to
200 km/h speed range. If ATTENTION ASSIST
detects typical indicators of fatigue or increas-
ing lapses in concentration on the part of the
driver, it suggests taking a break.
Important safety notes ATTENTION ASSIST is only an aid. It may not
always detect fatigue or lapses in concentration
until too late, or may not detect them at all. The system is not a substitute for a well-rested and
attentive driver.
The functionality of ATTENTION ASSIST is
restricted, and warnings may be delayed or not
occur at all in the following situations:
R if the length of the journey is less than approx-
imately 30 minutes
R if the road condition is poor, e.g. if the surface
is uneven or contains potholes
R in case of strong side winds
R if you have adopted a sporty driving style with
high cornering speeds or high rates of accel-
eration
R if you are predominantly driving at a speed
below 60 km/h or above 200 km/h
R if you are driving with DISTRONIC PLUS Steer-
ing Assist activated
R if the time has been set incorrectly
R in active driving situations, such as when you
change lanes or change your speed
The ATTENTION ASSIST tiredness assessment
is deleted and restarted when you continue the
journey in the following situations:
R you switch off the engine
R you take off your seat belt and open the driv-
er's door, e.g. for a change of drivers or to

G
WARNING
You could lose control of the vehicle/trailer
combination if it begins to swerve. The vehi-
cle/trailer combination could even overturn.
There is a risk of an accident.
On no account should you attempt to
straighten out the vehicle/trailer combina-
tion by increasing speed. Decrease your
speed and do not countersteer. Brake if nec-
essary. G
WARNING
If the maximum permissible load for a carrier system is exceeded, the carrier could come
loose from the vehicle and endanger other
road users. There is a risk of an accident and injury.
Never exceed the maximum permissible load
when using a carrier.
! 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.
Retrofitting a trailer tow hitch is only permissible
if a trailer load is specified in your vehicle docu-
ments. If this is not the case, then the vehicle is not approved for towing a trailer.
For more information, please contact a qualifiedspecialist workshop.
Exceeding the maximum permissible nose-
weight of the trailer drawbar on the ball coupling
may cause damage.
Damage may be caused to the following:

Towing a trailerDriving and parking

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
brake system and prevents the brakes from
overheating and wearing too quickly. If you need additional braking, depress the brake pedal
repeatedly rather than continuously.
Driving tips R
Maintain a greater distance to the vehicle in
front than when driving without a trailer.
R Avoid braking abruptly. If possible, brake gen-
tly at first to allow the trailer to run on. Then,
increase the braking force rapidly.
R The values given for gradient-climbing capa-
bilities from a standstill refer to sea level.
When driving in mountainous areas, note that
the power output of the engine, and conse-
quently the vehicle's gradient-climbing capa-
bility from a standstill, decrease with increas- ing altitude.
If the trailer swings from side to side:
X Do not accelerate under any circumstances.
X Do not countersteer.
X Brake, if necessary. Swivelling the ball coupling in/out
