process begins as soon as the charging
cable is connected.

you insert the charging cable into the
vehicle's power socket. However, this is
only the case if you have not made any
departure time settings.

WARNING
When connected to a power supply socket, a
high electrical load during the charging
process can lead to overheating of the
external power supply. There is a risk of
fire.
Check the maximum permissible charge
current on site before you begin the charg-
ing process. Contact an authorized electric drive smart center should you require
assistance. If necessary, adjust the set-
tings of your vehicle.
You can limit the charge current of the
high‑voltage battery. This can protect the
power supply from overloading. You can set
the limit either on the control unit of the
charging cable or via the control system.
The preset standard value is "Max". This
corresponds to the maximum available
charge current of the power supply.
Check the maximum permissible charge
current for the respective power supply
socket before charging the high‑voltage
battery.
The following values are available for
selection: 8 A,12 A,Max. The last value set
remains stored until a change is made.

WARNING
In order to avoid distraction which could
lead to an accident, the driver should enter system settings with the vehicle at a stand- still and operate the system only when roadand traffic conditions permit. Always pay
full attention to traffic conditions first
before operating system controls while
driving.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approx-
imately 14 m) every second. G
WARNING
Always select a volume that allows you to
still hear ambient sound in your immediate vicinity (e.g. horns, emergency rescue
vehicles, police vehicles, etc.). You could
otherwise cause an accident. G
WARNING
If you wish to have an audio system other
than an original smart audio system fitted
in your vehicle, please always have the nec- essary work performed at an authorized
smart center.
This is particularly important if your
vehicle is fitted with a radio preinstalla-
tion. Improper connection can result in the
failure of important vehicle functions,
thereby endangering the operating safety
of your vehicle and thus your own safety and that of other people.
The following pages contain a brief
description of the audio systems available for the coupé and cabriolet.

Cruise control*
The cruise control maintains the speed you set for your vehicle automatically. On
downhill grades, the cruise control does
not brake the vehicle via the brake system.
The cruise control can only use the braking power of the engine. You must apply the
brakes yourself in order to reduce the
vehicle speed. The cruise control will then
be canceled. G
WARNING
The cruise control is a convenience system designed to assist the driver during vehi-
cle operation. The cruise control cannot
take road, traffic, and weather conditions
into account. The driver is and must always
remain responsible for the vehicle’s speed and for safe brake operation. Do not use the cruise control
R if the road, traffic, and weather condi-
tions do not make it advisable to travel at
a constant speed

Rapid changes in tire traction can result
in wheel spin and loss of control.

The use of the cruise control is recommen-
ded for driving at a constant speed for
extended periods of time.

WARNING
The “Resume” function should only be oper- ated if the driver is fully aware of the pre-viously set speed and wishes to resume this particular preset speed.

acceleration or deceleration differences
arising from returning to the preset speed
could cause an accident and/or serious
injury to you and others. 98

Use only charging cables which have been
approved and recommended for the vehicle.
Do not use:
R extension chords
R cable reels
R multiple sockets
R travel adapters
i When possible, only charge the high-
voltage battery when the charge level is
below 80 %.
It is recommended to charge the high-
voltage battery prior to reaching less
than 20% state of charge.
Discharged high-voltage battery When the high-voltage battery is com-
pletely discharged, the drive system is
switched off. This protects the battery
from exhaustive discharge.
i By switching the ignition off and on
again, the drive system can be briefly
reactivated once. This allows you to park the vehicle safely.
Do not allow your vehicle to remain sta-
tionary for more than 14 days with a dis-
charged, or nearly discharged, high-volt-
age battery. You can check the charge level with the charge level gauge (Y page 81).
High or low outside temperatures The efficiency of the high-voltage battery
is temperature-dependent and decreases
at high or low temperatures. Additionally, the electrolytes used can gel at very low
temperatures.
You can check the maximum capacity avail-
able using the indicator in the multifunc- tion display (Y page 87). Energy consumption and range The available energy of the high-voltage
battery is reduced by:
R low outside temperatures
R switching on electrical consumers
At low temperatures and after being parked for an extended period without charging,
the physical properties of the high-volt-
age battery:
R can cause a significant reduction in the
performance of the battery
R can lead to longer charging times
In extreme cases, you will not be able to
start the vehicle. For this reason, always
connect the charging cable or make sure the battery is completely charged when park-
ing the vehicle in low outside tempera-
tures or for an extended period of time.
Due to its physical properties, the capa-
city of a high-voltage battery decreases
over its lifespan.
Thus, the following are reduced:
R the maximum attainable range of the
vehicle
R the maximum performance output (accel-
eration) of the vehicle
You can actively contribute to the reduc-
tion of the vehicle's energy consumption
by:
R driving conservatively
R maintaining the vehicle regularly
R decreasing the use of electrical consum-
ers
Notes on battery care Avoid storing and transporting the vehicle
at high temperatures for extended periods
of time (e. g. container transport).
When out of use for longer periods of time,
connect the vehicle to a voltage supply.
