In situations like this, the body, the under-
body, chassis parts, wheels or tyres could be
damaged without the damage being visible.
Components damaged in this way can unex-
pectedly fail or, in the case of an accident, no longer withstand the strain they are designed
for.
In such situations, have the vehicle checked
and repaired immediately at a qualified spe-
cialist workshop. If, upon continuing your
journey, you notice that driving safety is
impaired, pull over and stop the vehicle imme- diately, paying attention to road and traffic
conditions. In such cases, consult a qualified
specialist workshop.
If you make changes to electronic components,
their software or wiring, the general operating
permit for your vehicle may be rendered invalid.
Danger of electric shock G
DANGER
The vehicle's high voltage electrical system is under high voltage. If you modify components
in the vehicle's high-voltage electrical system or touch damaged components, you may be
electrocuted. The components in the vehi-
cle's high-voltage electrical system may be
damaged in an accident, although the damage
is not visible. There is a risk of fatal injury.
Do not touch any high-voltage components
after an accident and never modify the vehi-
cle's high-voltage electrical system. Have the vehicle towed away after an accident and the vehicle's high-voltage electrical system
checked by a qualified specialist workshop. All of the vehicle's high-voltage electrical sys-
tem components are marked with yellow warn- ing stickers which warn you about high voltages.
The cables of the vehicle's high-voltage electri-
cal system are orange.
When towing a vehicle after an accident, be sure to observe the following sections:
R Transporting the vehicle (Y page 263)
R Towing the vehicle with the front axle raised
(Y page 262)
R Towing the vehicle with both axles on the
ground (Y page 262)
Read the important safety instructions on tow-
ing away (Y page 260).
The ignition must be switched off when carrying out general tasks, such as changing bulbs or
checking the coolant level.
Automatic switching off of the vehicle's high-voltage electrical system If the restraint systems are activated during an
accident, the vehicle's high-voltage electrical
system is automatically deactivated.
This is to ensure that you do not come into con-
tact with high voltage.
Automatic protection from switching
on of the vehicle's high-voltage electri-
cal system The vehicle's high-voltage electrical system is
not activated when the vehicle is started if:
R a serious electrical insulation fault is detected
in the vehicle's high-voltage electrical system
R an electrical connection in the vehicle's high-
voltage electrical system is disconnected
Automatic switching off of the charging
process The charging process is deactivated automati-
cally if:
R the high-voltage battery is fully charged.
The charging process is interrupted automati-
cally if:
R a serious electrical insulation fault is detected
in the vehicle's high-voltage electrical system
R an electrical connection in the vehicle's high-
voltage electrical system is disconnected Introduction

General notes In order to prevent the vehicle's battery from
discharging, the interior lighting functions are
automatically deactivated after some time
except when the key is in position 2in the igni-
tion lock.
The colour and brightness for the ambient light- ing may be set using COMAND Online or Audio
20 (see the separate operating instructions).

To switch on: set the switch to centre posi-
tion B.
X To switch off: set the switch to the |

The interior lighting automatically switches on if you:
R unlock the vehicle
R open a door
R remove the key from the ignition lock
The interior lighting is activated for a short time
when the key is removed from the ignition lock.
This delayed switch-off can be adjusted using
COMAND Online or Audio 20 (see the separate
operating instructions). Manual interior lighting control X
To switch the front interior lighting on: set
the switch to the cposition.
X To switch off the interior lighting: set the
switch to the |position or (if the door is
closed) to the centre position.

gency lighting: press the hazard warning
lamp button.

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

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). Running-in notes
In certain driving and driving safety systems, the sensors adjust automatically while a certain dis-
tance is being driven after the vehicle has been delivered or after repairs. Full system effective- ness is not reached until the end of this teach-in
process.
Brake pads/linings and discs that are either new or have been replaced only achieve optimum
braking effect after several hundred kilometres
of driving. Compensate for the reduced braking
effect by applying greater force to the brake
pedal. Driving
Important safety notes
G
WARNING
Objects in the driver's footwell may restrict
the clearance around the pedals or block a
depressed pedal. This jeopardises the oper-
ating and road safety of the vehicle. There is a risk of an accident.
Stow all objects securely in the vehicle so that
they do not get into the driver's footwell.
Always fit the floormats securely and as pre-
scribed in order to ensure that there is always sufficient room for the pedals. Do not use
loose floormats and do not place several floor- mats on top of one another. G
WARNING
Unsuitable footwear can hinder correct usage of the pedals, e.g.:
R shoes with thick soles
R shoes with high heels
R slippers
There is a risk of an accident.
Wear suitable footwear to ensure correct
usage of the pedals. G
WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk of an accident.
Do not switch off the ignition while driving. G
WARNING
If the parking brake has not been fully
released when driving, the parking brake can:
R overheat and cause a fire
R lose its hold function.
There is a risk of fire and an accident. Release
the parking brake fully before driving off.
! Before driving away, you must ensure that,
for your own safety and to avoid damage, the charging cable has been removed from the
vehicle socket. Otherwise, you cannot shift
the transmission out of position P.
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
If you do not make an additional effort to apply
the brake yourself, the braking effect may not be Driving
