Warning display
Blind Spot Assist is not active at speeds below approximately 20 mph (30 km/h). Vehicles in the monitoring range are then not indicated.
When Blind Spot Assist is activated, indicator
lamp :in the exterior mirrors lights up yel-
low at speeds of up to 20 mph (30 km/h). At speeds above 20 mph (30 km/h), the indica-
tor lamp goes out and Blind Spot Assist is
operational.
If a vehicle is detected within the blind spot
monitoring range at speeds above 20 mph
(30 km/h), warning lamp :on the corre-
sponding side lights up red. This warning is
always emitted 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 7 mph (12 km/h).
The yellow indicator lamp goes out if reverse gear is engaged. In this event, Blind Spot
Assist is no longer active.
The brightness of the indicator/warning
lamps is adjusted automatically according to
the ambient light.
Collision warning If a vehicle is detected in the monitoring range
of Blind Spot Assist and you switch on the
corresponding turn signal, a double warning
tone sounds. Red warning lamp :flashes. If
the turn signal remains on, detected vehicles
are indicated by the flashing of red warning
lamp :. There are no further warning tones. Switching on Blind Spot Assist X
Make sure that Blind Spot Assist is activa-
ted in the on-board computer
(Y page 195).
X Turn the SmartKey to position 2in the igni-
tion lock.
Warning lamps :in the exterior mirrors
light up red for approximately 1.5 seconds
and then turn yellow. Driving systems

Useful information
i This Operator's Manual describes all
models and all standard and optional equip- ment of your vehicle available at the time of
publication of the Operator's Manual.
Country-specific differences are possible.
Please note that your vehicle may not be
equipped with all features described. This
also applies to safety-related systems and
functions.
i Read the information on qualified special-
ist workshops (Y page 25). Important safety notes
G
WARNING
If you operate information systems and com-
munication equipment integrated in the vehi- cle while driving, you will be distracted from
traffic conditions. You could also lose control of the vehicle. There is a risk of an accident.
Only operate the equipment when the traffic
situation permits. If you are not sure that this
is possible, park the vehicle paying attention
to traffic conditions and operate the equip-
ment when the vehicle is stationary.
You must observe the legal requirements for
the country in which you are currently driving when operating the on-board computer. G
WARNING
If the instrument cluster has failed or mal-
functioned, you may not recognize function
restrictions in systems 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 mul- tifunction display. You should therefore make sure your vehicle is operating safely at all
times.
If the operating safety of your vehicle is
impaired, pull over as soon as it is safe to do
so. Contact a qualified specialist workshop.
For an overview, see the instrument panel
illustration (Y page 31). Displays and operation
Instrument cluster lighting
The light sensor in the instrument cluster
automatically controls the brightness of the
multifunction display. In daylight, the displays
in the instrument cluster are not illuminated.
The lighting in the instrument cluster, in the
displays and the controls in the vehicle inte-
rior can be adjusted using the brightness con- trol knob.
The brightness control knob is located on the
bottom left of the instrument cluster
(Y page 31).
X Turn the brightness control knob clockwise
or counter-clockwise.
If the light switch is set to Ã,Tor
L, 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 indi- cates that the vehicle is operational. 182

Outside temperature display
You should pay special attention to road con-
ditions when temperatures are around freez-
ing point.
Bear in mind that the outside temperature
display indicates the temperature measured
and does not record the road temperature.
The outside temperature display is in the mul- tifunction display (Y page 186).
Changes in the outside temperature are dis-
played after a short delay. E-CELL display

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 133).
E-CELL display :shows the available
power of the drive system.
Under normal operating conditions, E-CELL
display :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
longer period of time R
very low condition of charge 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 140). 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
display Ready
Ready appears in the lower multifunc-
tion display. The vehicle is ready to drive.
The boost area for maximum acceleration can
be reached using kickdown (Y page 137). Displays and operation
183On-board computer and displays Z

The braking performance of the electric
motor using recuperative braking is, in some
operating modes, either reduced or not effec-
tive:
R when the condition of charge of the high-
voltage battery increases
R if the high-voltage battery is not yet at a
normal 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
If necessary, counteract the reduced regen-
erative braking effect by applying the brake
yourself. Charge level display
Condition of charge display
:shows the
condition of charge of the high-voltage bat-
tery.
The charge value is shown as a percentage in

cluster (Y page 187).

Energy Flow menu can also be dis-
played in the COMAND/Audio display.

battery has dropped into the reserve range if
the drive system is running and:
R the Drive Drive Battery

Levelmes-
sage appears in the display
R the indicator lamp in the instrument cluster
lights up Charge the high-voltage battery from a con-
dition of charge of less than 20% at:
R an electrical outlet
R a charging station
The braking performance of the electric
motor using recuperative braking is, in some
operating modes, either reduced or not effec-
tive:
R when the condition of charge of the high-
voltage battery increases
R if the high-voltage battery is not yet at a
normal 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, counter-
act the reduced regenerative braking effect
by applying the brake yourself. Operating the on-board computer
