The warning displays show the distance
between the sensors and the obstacle. The
warning display for the front area is located on
the dashboard above the centre air vents. The
warning display for the rear area is located on
the roof lining in the rear compartment.
The warning display for each side of the vehicle
is divided into five yellow and two red segments.
PARKTRONIC is operational if yellow segments
showing operational readiness =light up.
The transmission position of the automatic
transmission and the direction in which the vehi-
cle is rolling determine which warning display is active when the engine is running. Transmission posi-

cle's distance from the obstacle.
From the:
R sixth segment onwards, you will hear an inter-
mittent warning tone for approximately two
seconds.
R seventh segment onwards, you will hear a

Parking tips:
R The way your vehicle is positioned in the park-
ing space after parking is dependent on vari-
ous factors. These include the position and
shape of the vehicles parked in front and
behind it and the conditions of the location. It
may be the case that Active Parking Assist
guides you too far into a parking space, or not
far enough into it. In some cases, it may also
lead you across or onto the kerb. If necessary, you should cancel the parking procedure withActive Parking Assist.
R You can also preselect transmission position
D. The vehicle redirects and does not drive as
far into the parking space. Should the trans-
mission change take place too early, the park-
ing procedure will be cancelled. A sensible
parking position can no longer be achieved
from this position.
Exiting a parking space In order that Active Parking Assist can support
you when exiting the parking space:
R you need to have parked using Active Parking
Assist.
R the border of the parking space must be high
enough at the front and the rear. A kerb stone is too small, for example.
R the border of the parking space must not be
too wide, as the position of the vehicle must
not exceed an angle of 45° to the starting
position as it is manoeuvred into the parking
space.
R a manoeuvring distance of at least 1.0 mmust
be available.
Active Parking Assist can only assist you with
exiting a parking space if you have parked the
vehicle parallel to the direction of travel using
Active Parking Assist. 160

Reversing camera
General notes Reversing camera
:is an optical parking and
manoeuvring aid. It uses guide lines to show the
area behind your vehicle in the Audio/COMAND
display.
The area behind the vehicle is displayed as a
mirror image, as in the rear-view mirror.
i The text shown in the Audio/COMAND dis-
play depends on the language setting. The
following are examples of reversing camera
displays in the Audio/COMAND display.
See the notes on cleaning (Y page 246).
Important safety notes The reversing camera is only an aid. It is not a
substitute for your attention to the immediate
surroundings. The responsibility for safe
manoeuvring and parking remains with you.
Make sure that there are no persons, animals or
objects in range while manoeuvring and parking.
Under the following circumstances, the revers-
ing camera will not function, or will function in a limited manner:
R if the tailgate is open
R in heavy rain, snow or fog
R at night or in very dark places
R if the camera is exposed to very bright light
R if the area is lit by fluorescent bulbs or LED
lighting (the display may flicker)
R if there is a sudden change in temperature,
e.g. when driving into a heated garage in win-
ter R
if the camera lens is dirty or obstructed.
Observe the notes on cleaning
(Y page 246)
R if the rear of your vehicle is damaged. In this
case, have the camera position and setting
checked at a qualified specialist workshop.
The field of vision and other functions of the
reversing camera may be restricted due to addi-
tional accessories on the rear of the vehicle (e.g. licence plate holder, bicycle rack).
Activating/deactivating the reversing
camera X
To activate: make sure that the key is in
position 2in the ignition lock.
X Make sure that the Activation by R gear Activation by R gear
function is selected in Audio 20/COMAND
Online; see the Digital Owner's Manual.
X Engage reverse gear.
The area behind the vehicle is shown with
guide lines in the Audio 20/COMAND Online
display.
The image from the reversing camera is avail-
able throughout the manoeuvring process.
To deactivate: the reversing camera deacti-
vates if you shift the transmission to Por after
driving forwards a short distance.
Displays in the Audio 20/COMAND dis-
play The reversing camera may show a distorted view
of obstacles or show them incorrectly or not at
all. Obstacles are not shown by the reversing
camera in the following locations:
R very close to the rear bumper
R under the rear bumper
R in the area immediately above the tailgate
handle
! Objects not at ground level may appear to
be further away than they actually are, e.g.:
R the bumper of a parked vehicle
R the drawbar of a trailer
R the ball coupling of a trailer tow hitch
R the rear section of an HGV
R a slanted post
Use the guidelines only for orientation.
Approach objects no further than the bottom- most guideline. 162

WARNING
There is a risk of an accident if you accelerate or overtake when the power output of the
drive system is reduced.
You should therefore adapt your driving style
and drive particularly carefully. Charge the
high-voltage battery at a charge station imme- diately. X
Start the drive system (Y page 128).
E-CELL display :shows the available power
of the drive system.
Under normal operating conditions, E-CELL dis-
play :is in the maximum range.
The power output available may deviate from
the maximum range in the event of:
R very high or low outside temperatures
R very high performance requirements for a lon-
ger period of time
R very low charge status of the high-voltage
battery
R a malfunction in the drive system
The reduced power output can be improved by
charging the high-voltage battery (Y page 134). Power display
Power display
:contains two areas:
R Area above 0
Here, the current amount of power that the
drive system is feeding to the wheels is dis-
played.
R Area below 0
Here, the vehicle's recuperative power in
overrun mode is displayed.
If the needle for the power display is in the OFF
position, the vehicle is not ready to drive
because:
R the drive system has not yet started
R the charging cable is still connected to the
vehicle socket
R there is insufficient power available from the
high-voltage battery
R the vehicle's high-voltage electrical system is
malfunctioning
When the drive system is started, the needle in
the power display moves to position 0. The dis-
play Ready
Ready appears in the lower multifunction
display. The vehicle is ready to drive.
The boost area for maximum acceleration can
be reached using kickdown (Y page 131).
The braking performance of the electric motor
using recuperative braking is, in some operating
modes, either reduced or not effective:
R when the charge status of the high-voltage
battery increases
R if the high-voltage battery is not yet at a nor-
mal operating temperature
R when driving close to the maximum speed
R when the vehicle is almost stationary
R in transmission position N
R during and after ESP stability control Displays and operation
173On-board computer and displays Z

If necessary, counteract the reduced regenera-
tive braking effect by applying the brake your-
self. Charge level display
Charge status display
:shows the charge sta-
tus of the high-voltage battery.
The charge value is shown as a percentage in the
energy flow
energy flow menu in the instrument cluster
(Y page 177).
i The
energy flow
energy flow menu can also be dis-
played n the COMAND/Audio display.
The charge level of the high-voltage battery has dropped into the reserve range if the drive sys-
tem is running and:
R the Drive battery Reserve level Drive battery Reserve level mes-
sage appears in the display
R the indicator lamp in the instrument cluster
lights up
Charge the high-voltage battery from a state of
charge of less than 20% at a:
R mains socket
R charging station
The braking performance of the electric motor
using recuperative braking is, in some operating
modes, either reduced or not effective:
R when the charge status of the high-voltage
battery increases
R if the high-voltage battery is not yet at a nor-
mal operating temperature
R when the vehicle is almost stationary
R in transmission position N
R during and after ESP stability control
If you do not make an additional effort to apply
the brake yourself, the braking effect may not be sufficient. If necessary, counteract the reduced regenerative braking effect by applying the
brake yourself. Operating the on-board computer
