Warning display
:
Warning display
Blind Spot Assist is not active at speeds below
approximately 30 km/h. Vehicles in the moni-
toring range are then not indicated.
If Blind Spot Assist is activated, indicator
lamp :in the exterior mirrors lights up yellow
up to a speed of 30 km/h. At speeds above
30 km/h, the indicator lamp goes out and Blind
Spot Assist is operational.
If a vehicle is detected within the monitoring
range of Blind Spot Assist at speeds above
30 km/h, warning lamp :on the correspond-
ing side lights up red. This warning always
occurs when a vehicle enters the blind spot
monitoring range from behind or from the side.
When you overtake a vehicle, the warning only
occurs if the difference in speed is less than
12 km/h.
The yellow indicator lamp goes out if reverse
gear is engaged. Blind Spot Assist is then deac- tivated.
The brightness of the indicator/warning lamps
is adjusted automatically according to the ambi-
ent light.
Collision warning
If a vehicle is detected in the monitoring range of
Blind Spot Assist and you switch on the corre-
sponding turn signal, a double warning tone
sounds. Red warning lamp :flashes. If the turn
signal remains on, detected vehicles are indica-
ted by the flashing of red warning lamp :.
There are no further warning tones. Activating Blind Spot Assist
X Make sure that Blind Spot Assist is activated
in the on-board computer (Y page 183).
X Turn the key to position 2in the ignition lock.
Warning lamps :in the exterior mirrors light
up red for approximately 1.5 seconds and
then turn yellow.
Lane Keeping Assist General notes
Lane Keeping Assist monitors the area in front of
your vehicle by means of multifunction cam-
era :attached at the top of the windscreen.
Lane Keeping Assist detects lane markings on
the road and can warn you before you leave your lane unintentionally.
This function is available in a speed range
between 60 km/h and 200 km/h.
A warning may be given if a front wheel passes
over a lane marking. It will warn you by means of intermittent vibration through the steering
wheel for up to 1.5 seconds.
Important safety notes G
WARNING
Lane Keeping Assist cannot always clearly
identify lane markings.
In these cases, Lane Keeping Assist may:
R give an unnecessary warning
R not give a warning
There is a risk of an accident.
Always pay particular attention to the traffic
situation and keep in lane, especially if Lane
Keeping Assist alerts you. 170

Useful information
i This Owner's Manual describes all models,
series and optional equipment for your vehi-
cle that were available at the time of going to
press. National variations are possible. Note
that your vehicle may not be equipped with all
of the functions described. This is also the
case for systems and functions relevant to
safety.
i Read the information on qualified specialist
workshops: (Y page 23). Important safety notes
G
WARNING
Operating the integrated information systems and communications equipment in the vehicle
while driving will distract you from traffic con-
ditions. You could then lose control of the
vehicle. There is a risk of an accident.
Only operate these devices if road traffic con-
ditions permit. If you are unsure about the
surrounding conditions, pull over to a safe
location and make entries only while the vehi-
cle is stationary.
You must observe the legal requirements for the country in which you are currently driving whenoperating the on-board computer. G
WARNING
If the instrument cluster has failed or mal-
functioned, you may not recognise function
restrictions relevant to safety. The operating
safety of your vehicle may be impaired. There is a risk of an accident.
Drive on carefully. Have the vehicle checked
at a qualified specialist workshop immedi-
ately.
The on-board computer only shows messages or warnings from certain systems in the multifunc-tion display. You should therefore make sure
your vehicle is operating safely at all times.
If the operating safety of your vehicle is
impaired, park the vehicle safely as soon as pos- sible. Contact a qualified specialist workshop. For an overview, see the instrument panel illus-
tration (Y page 27). Displays and operation
Instrument cluster lighting
The light sensor in the instrument cluster auto-
matically controls the brightness of the multi-
function display. In daylight, the displays in the
instrument cluster are not illuminated.
The lighting in the instrument cluster, in the dis- plays and the controls in the vehicle interior can
be adjusted using the brightness control knob.
The brightness control knob is located on the
bottom left of the instrument cluster
(Y page 27).
X Turn the brightness control knob clockwise or
anti-clockwise.
If the light switch is set to the Ã,Tor
L position, the brightness is dependent
upon the brightness of the ambient light. READY indicator
When the drive system is started and the vehicle
is ready to drive, READY indicator :appears in
the multifunction display. This indicates that the vehicle is operational. Outside temperature display
You should pay special attention to road condi-
tions when temperatures are around freezing
point.
Bear in mind that the outside temperature dis-
play indicates the measured air temperature
and not the road surface temperature.
The outside temperature display is in the multi-
function display (Y page 175).
There is a short delay before a change in outside
temperature appears in the multifunction dis-
play. 172

sage appears in the display
R the indicator lamp in the instrument cluster

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
