360° camera
General notes
The 360° camera is a system consisting of four
cameras.
The system processes images from the follow-
ing cameras:
RRear view camera
RFront camera
RTwo cameras in the exterior rear view mirrors
The cameras cover the immediate surroundings
of the vehicle. The 360° camera assists you, for
instance when parking or at exits with reduced
visibility.
You can show pictures from the 360° camera in
full-screen mode or in seven different split-
screen views on the multimedia system display.
A split-screen view also includes a top view of
the vehicle. This view is calculated from the data
supplied by the installed cameras (virtual cam-
era).
The six split-screen views are:
RTop view and picture from the rear view cam-
era (130° viewing angle)
RTop view and image from the front camera
(130° viewing angle without displaying the
maximum steering wheel angle)
RTop view and enlarged rear view
RTop view and enlarged front view
RTop view and trailer view (vehicles with trailer
tow hitch)
RTop view and rear-view images from the exte-
rior mirror cameras (rear wheel view)
RTop view and forward-view images from the
exterior mirror cameras (front wheel view)
When the function is active and you shift the
transmission from hork toi, the dynamic
guide lines are hidden.
When you shift between transmission positions
h and k, you see the previously selected front
or rear view.
Distances measured by Parking Assist
PARKTRONIC will also be optically displayed:
Rin split screen view as red or yellow brackets
around the vehicle icon in the top view, or
Rat the bottom right as red or yellow brackets
around the vehicle symbol in full-screen mode
The line thickness and color of the brackets
show how far the vehicle is away from an object:

ATTENTION ASSIST
General notes
ATTENTION ASSIST helps you during long,
monotonous journeys, such as on highways. It is
active in the 37 mph (60 km/h) to 125 mph
(200 km/h) 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 to the driver. It
might not always recognize fatigue or increasing inattentiveness in time or fail to recognize 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:
Rif the length of the journey is less than approx-
imately 30 minutes
Rif the road condition is poor, e.g. if the surface
is uneven or if there are potholes
Rif there is a strong side wind
Rif you have adopted a sporty driving style with
high cornering speeds or high rates of accel-
eration
Rif you are predominantly driving slower than
37 mph (60 km/h) or faster than 125 mph
(200 km/h)
Rif you are driving with the Steering Pilot of
Distance Pilot DISTRONIC activated
Rif the time has been set incorrectly
Rin active driving situations, such as when you
change lanes or change your speed
202Driving systems
Driving and parking

Most U.S. states and all Canadian provinces
require by law:
RSafety chains between the towing vehicle and
the trailer. The chains should be cross-wound
under the trailer drawbar. They must be fas-
tened to the vehicle's trailer coupling, not to
the bumper or the axle.
Leave enough play in the chains to make tight
cornering possible.
RA separate brake system for certain types of
trailer.
RSafety switch for braked trailers. Check the
specific legal requirements applicable to your
state.
If the trailer becomes detached from the tow-
ing vehicle, the safety feature triggers the
trailer brakes.
Towing a trailer
There are numerous legal requirements con-
cerning the towing of a trailer, e.g. speed restric-
tions. Make sure that your car/trailer combina-tion complies with the local regulations:
Rin your place of residence
Rin the location to which you are driving
The police and local authorities can provide reli-
able information.
Observe the following when towing a trailer:
RTo gain driving experience and to become
accustomed to the new handling characteris-
tics, you should practice the following in a
traffic-free location:
-cornering
-stopping
-backing up
RBefore driving, check:
-trailer tow hitch
-safety switch for braked trailers
-safety chains
-electrical connections
-lights
-wheels
RAdjust the exterior mirrors to provide an
unobstructed view of the rear section of the
trailer.
RIf the trailer has electronically controlled
brakes, pull away carefully. Brake manually using the brake controller and check whether
the brakes function correctly.
RSecure any objects on the trailer to prevent
the cargo from slipping when the vehicle is in
motion.
RWhen you couple up a trailer, check at regular
intervals that the load is firmly secured. If the
trailer is equipped with trailer lights and
brakes, check the trailer to ensure that these
are working.
RBear in mind that the handling will be less
stable when towing a trailer than when driving
without one. Avoid sudden steering move-
ments.
RThe vehicle/trailer combination is heavier,
accelerates more slowly, has a decreased
gradient climbing capability and a longer
braking distance.
It is more susceptible to side winds and
requires more careful steering.
RIf possible, do not brake suddenly, but instead
depress the brake pedal moderately at first so
that the trailer can activate its brakes. Then
increase the pressure on the brake pedal.
RIf the automatic transmission repeatedly
shifts between gears on uphill or downhill gra-
dients, shift to a lower gear using the left-hand
steering wheel paddle shifter.
A lower gear and lower speed reduce the risk
of engine failure.
RWhen driving downhill, shift to a lower gear to
utilize the engine's braking effect.
Avoid continuous brake application as this
may overheat the vehicle brakes and, if instal-
led, the trailer brakes.
RIf the coolant temperature increases dramat-
ically while the air-condit ioning system is
switched on, switch off the air-conditioning
system.
Coolant heat can also be dissipated by open-
ing the windows and switching the ventilation blower and the interior temperature to the
highest level.
RWhen overtaking, pay particular attention to
the extended length of your vehicle/trailer
combination.
Due to the length of the vehicle/trailer com-
bination, you require additional road space in
relation to the vehicle you are overtaking
before you can change back to the original
lane.
