Important safety notes
Xenon bulbs G
DANGER
Xenon bulbs are under high voltage. You can
get an electric shock if you remove the cover
of the xenon bulb and touch the electrical
contacts. There is a risk of fatal injury.
Never touch the parts or the electrical con-
tacts of the xenon bulb. Always have work on the xenon bulbs carried out at a qualified spe- cialist workshop.
If your vehicle is equipped with xenon bulbs, you can recognise this by the following: the cone of
light from the xenon bulbs moves from the top to the bottom and back again when you start the
drive system. For this to be observed, the lights
must be switched on before the drive system is started.
Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure
that these function correctly at all times. Have
the headlamp setting checked regularly. Replacing bulbs

General notes If you deactivate the "Cooling with air dehumid-
ification" function, the air inside the vehicle will
not be cooled. The air inside the vehicle will also
not be dehumidified. The windows can mist up
more quickly. Therefore, only deactivate the
"Cooling with air dehumidification" function
briefly.
The "Cooling with air dehumidification" function
is operational when the vehicle is ready to drive. The air inside the vehicle is cooled and dehu-
midified according to the temperature selected.

Operating the climate control systemClimate control

Energy consumption and range
This range is reduced by:
R high and low outside temperatures
R a non-anticipatory driving style
R switching on consumers, e.g. air-conditioning
system or heating.
The battery's physical characteristics are such
that leaving the vehicle parked for an extended
period at low outdoor temperatures without
charging it can lead to:
R a reduction in battery performance
R longer charge times
In extreme cases, this could mean that the vehi- cle cannot be started. For this reason, connect
the charging cable when leaving the vehicle
parked for long periods at low outdoor temper-
atures.
As a result of its basic characteristics, the
amount of energy available from the high-volt-
age battery decreases over the course of its life.
This reduces:
R the maximum range that can be achieved by
the vehicle
R the maximum output (acceleration) of the
vehicle
You can actively reduce the energy consump-
tion of your vehicle in a number of ways, for
example, by:
R an anticipatory driving style
R reducing the use of electrical consumers
R having the vehicle regularly maintained
The charging time of the high-voltage battery
may change over the course of its life.
Observe the displays on energy usage
(Y page 178) and range (Y page 178).
RANGE PLUS If you activate RANGE PLUS, the operating win-
dow of the battery will be extended at the next
charging process. An extended driving range will
be available to you for the next journey.
Using RANGE PLUS shortens the service life of
the battery. Therefore, only use RANGE PLUS if, for example:
R long journeys are planned or
R the availability of charging stations at the des-
tination is limited The more often RANGE PLUS is used, the more
the extended range is reduced.
Therefore always check the range display for
every journey (Y
page 178). X
To switch on: press button:.
The green indicator lamp lights up.
X To switch off: press button:.
The indicator lamp goes out.
RANGE PLUS switches off automatically if:
R the charging cable is disconnected or
R the charging process is complete

the mains socket
Charging cable Important safety notes
! Only use the charging cable to charge the
high-voltage battery. Do not use the charging
cable for other purposes. It may otherwise be damaged.
The vehicle is supplied with a three-phase 32 A
charging cable. A single-phase 13 A charging
cable (Switzerland: 16 A) can be optionally
ordered.
When charging the vehicle using the mains
socket, use the single-phase 13 A (Switzerland:
16 A) charging cable.
Observe the "Important safety notes"
(Y page 134).
If you use the supplied 13 A charging cable
(Switzerland: 16 A) as opposed to the 32 A
charging cable to charge the high-voltage bat-
tery:
R the charge time increases considerably
R electrical consumption increases considera-
bly
For this reason, always charge the high-voltage
battery from a wallbox (Y page 142) or at a
charging station (Y page 142). Only then can
certified electrical energy consumption levels
be reached.
i The charging process can vary depending on
the charging station. Therefore, always
observe the local information. High-voltage battery

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
