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 whenoperating 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 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, pull over as soon as it is safe to do so. Contact a qualified specialist workshop.
For an overview, see the instrument panel illus-
tration (Y page 32). 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 32).
X Turn the brightness control knob clockwise or
counter-clockwise.
If the light switch is set to the 0058,0060or
0058 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 0043appears 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 temperature measured and
does not record the road temperature.
The outside temperature display is in the multi-
function display (Y page 155).
There is a short delay before a change in outside
temperature appears in the multifunction dis-
play. E-CELL display
G
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. 152

Start the drive system (Y page 111).
E-CELL display 0043shows the available power
of the drive system.
Under normal operating conditions, E-CELL dis-
play 0043is 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 condition of charge of the high-volt-
age battery
R a malfunction in the drive system
The reduced power output can be improved by
charging the high-voltage battery (Y page 117).Power display
Power display
0043contains 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 114).
The braking performance of the electric motor
using recuperative braking is, in some operating
modes, either reduced or not effective:
R when the condition of charge of the high-volt-
age 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
If necessary, counteract the reduced regenera-
tive braking effect by applying the brake your-
self. Condition of charge display
Condition of charge display

dition of charge of the high-voltage battery.

drive system 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 condi-
tion 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 effective:
R when the condition of charge of the high-volt-
age 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
