Important safety notes The 360° camera is only an aid and may show
a distorted view of obstacles, show them
incorrectly or not at all. The 360° camera is
not a substitute for attentive driving.
You are responsible for safe manoeuvring and
parking. Make sure that there are no persons,
animals or objects in range while manoeu-
vring and parking.
You are always responsible for safety, and
must always pay attention to your surround-
ings when parking and manoeuvring. This
applies to the areas behind, in front of and
beside the vehicle. You could otherwise
endanger yourself and others.
The 360° camera will not function or will
function only in a limited manner:
R if the doors are open
R if the exterior mirrors are folded in
R if the boot lid is open
R in heavy rain, snow or fog
R at night or in very dark places
R if the cameras are exposed to very bright
light
R if the area is lit by fluorescent bulbs or LED
lighting (the display may flicker)
R if the camera lenses mist up, e.g. when
driving into a heated garage in winter, caus- ing a rapid change in temperature R
if the camera lenses are dirty or covered
R if the vehicle components in which the
cameras are fitted are damaged. In this
event, have the camera position and setting
checked at a qualified specialist workshop.
Do not use the 360° camera in this case. You could otherwise injure others or damage
objects when parking the vehicle.
Guide lines are always shown at road level.
In trailer mode, the guide lines are shown at
the level of the trailer coupling.
The camera in the rear area is protected by
means of a flap. This flap opens when the
360° camera is activated. Observe the notes
on cleaning (Y page 401). For technical rea-
sons, the flap may remain open briefly after
the 360° camera has been deactivated.

Stopping the 360° camera display As soon as the vehicle exceeds a speed of
30 km/h, the function switches off. The view
which was active before the 360° camera
was displayed appears in the COMAND dis-
play. You can also stop the 360° camera dis-
play from split-screen view by selecting the

ing with the COMAND controller.
Vehicles with automatic transmission: the
360° camera display is also ended if you
select transmission position P.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 range. If ATTENTION ASSIST
detects typical indicators of fatigue or
increasing 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 concentra-
tion 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:
R if the length of the journey is less than
approximately 30 minutes
R if the road condition is poor, e.g. if the sur-
face is uneven or if there are potholes
R if there is a strong side wind R
if you have adopted a sporty driving style
with high cornering speeds or high rates of
acceleration
R if you are predominantly driving at a speed
below 60 km/h or above 200 km/h
R if you are driving with the active Steer
Assist of DISTRONIC PLUS
R if the time has been set incorrectly
R in active driving situations, such as when
you change lanes or change your speed
ATTENTION ASSIST is reset and starts
assessing your tiredness again when you con- tinue your journey if:
R you switch off the engine
R you take off your seat belt and open the
driver's door, e.g. for a change of drivers or
to take a break
Displaying the attention level You can have current status information dis-
played in the assistance menu (Y

way.
R the system recognises solid lane markings.
The warning vibration occurs later if:
R the road has narrow lanes.

Towing a trailer
If you couple up a trailer, make sure that you have correctly established the electrical con-
nection. This can be accomplished by check- ing the trailer lighting. Hybrid operation
Points to remember
General notes Hybrid technology combines a fuel efficient
internal combustion engine with a powerful
electric motor. The hybrid system automati-
cally selects the most efficient operating
mode for every driving situation. Drive the
vehicle in the usual manner.
To save fuel, the hybrid system switches off
the combustion engine as often as possible
during the journey when power output requirements are low. When power output
requirements are low, the electric motor pow-
ers the vehicle. When power output require-
ments are high, the combustion engine is
switched on, even during a journey. When the vehicle is stationary, the combustion engine
is usually switched off. Consequently, there is
usually no engine idling as with combustion
engine vehicles.
For pulling away and accelerating, the electric motor supports the internal combustion
engine using the power stored in the high-
voltage battery. In addition, the power is used
for partially electric driving, operation of the
electric coolant compressor and to support
the 12 V on-board electrical system. In this
way the hybrid drive helps to reduce your
vehicle's fuel consumption.
Observe the driving tips on hybrid operation
(Y page 278).
RBS (Recuperative Brake System) If you release the accelerator pedal when the
vehicle is in motion, overrun recuperation is
initiated. The electric motor is operated as a
generator when in overrun mode and when
you brake. Hybrid technology converts the
kinetic energy of the vehicle into electricity
and stores it in the high-voltage battery. Important safety notes
All of the vehicle's systems remain active, if: R the vehicle is stationary,
R the combustion engine is switched off and
R the READY-indicator in the instrument clus-
ter is lit.
If you remove your foot from the brake pedal
while in transmission position D or R, the
vehicle could pull away automatically.
Observe the notes on the READY display of
the ECO start/stop function (Y page 279).
Vehicles with an electric motor generate sig-
nificantly less noise than vehicles with inter-
nal combustion engines. As a result, in certain Hybrid operation

X Turn the key to position 3in the ignition
lock (Y page 183) or press the Start/Stop
button once (Y page 184).
The vehicle is operational when READY indi-
cator :lights up.
Noiseless start The vehicle starts in electric mode without the
internal combustion engine. The internal
combustion engine starts only after the
power demanded by the driver exceeds the
available power that the electric motor can
currently provide.
Noiseless start operation is dependent on the
outside temperature and the operating tem-
perature of the internal combustion engine.
The vehicle is operational when READY indi-
cator :lights up. Pulling away

Using the steering wheel gearshift paddles,
you can temporarily change gear yourself.
The transmission must be in position D. Elec-
tric-only operation is not possible when man-
ually changing gear.

Driving tips General driving tips
Drive carefully and maintain a suitable dis-
tance from the vehicle in front. Avoid frequent
and sudden acceleration as well as abrupt
braking.
During partially electric driving, pulling away
and acceleration, the electric motor supports the internal combustion engine.
During overrun in transmission position Dand
braking, the electric motor operates as an
alternator.
To reduce fuel consumption, use:
R recuperative braking (Y page 269)
R overrun mode (Y page 280) or extended
overrun mode (Y page 280)
For further information on the ECO start/stop
function; see (Y page 279).
Additional driving tips (Y page 211).
Stationary vehicle
If the vehicle is stopped, the combustion
engine is, for the most part, switched off.
Automatic climate control continues to func-
tion. The electro-mechanically assisted steer-
ing gear allows use of the power steering
without loss of comfort. 278
