Charging operation
Hints Following safety instructions of the
power mains connection
During the charging process, heed the safety
instructions of the respective power mains
connection. Otherwise, there could be a risk of
personal injury or property damage from high
voltage, e.g., from electrocution or fire.◀
Using a Level 1 charging cable at other
household sockets
Before charging at other household sockets,
adapt the charging current strength to the
mains. Otherwise, there is a risk of fire, e.g.,
from overheating of the household socket or
overloading of the power mains.◀
Starting charging process
1.Engage selector lever position P. Set the
parking brake if needed.2.Planning charging process, refer to
page 165.3.Switch off drive readiness.4.Connect either a Level 1 or Level 2 charg‐
ing cable to the household socket or the
port on the charging station.5.Open charging port flap.6.Connect charging cable to the vehicle, re‐
fer to page 163.
At high temperatures, initially the high-voltage
battery is cooled. The charging process can be
started with a delay.
Display of the charging status
The charging status is indicated by the indica‐
tor light at the charging port.

the setting for charging.
Set the charge current strength at other
household sockets to "Low".
Setting charging via a
Level 2 charging cable
Depending on the electrical mains, the vehicle
must be charged with a different charging cur‐
rent strength, refer to page 160.
When charging with a Level 2 charging cable,
the charging process can be completed faster
at a Level 2 charging station.

Stopping charging process The charging operation can be stopped at any
time by removing the charging cable and con‐
tinued at a later time by connecting the charg‐
ing cable in order to use other loads on the
power connection or to prevent simultaneous
high power from multiple loads.
The charging operation is interrupted when the
vehicle is unlocked and automatically resumed
after a brief time or when it is locked.
Continue charging operation If the charging operation is interrupted, e.g.,
through a temporary power failure, the charg‐
ing operation is automatically continued after
the interruption.
Terminating charging process1.Removing the charging cable from the ve‐
hicle, refer to page 163.2.Stow the charging cable as required.3.Close the charging port flap.4.Lock vehicle if it is unlocked.
Displays in the instrument
cluster
The charging state indicator light, refer to page 77, shows the charging state of the high-
voltage battery in the instrument cluster, if op‐
erating readiness is switched on. If all seg‐
ments are filled, the high-voltage battery is
fully charged.
Even if no segments are filled, the high-voltage
system is still under high voltage.
Information regarding the charging process are
shown on the charging screen, refer to
page 76.

Climate controlGeneral information
The following settings for climate control of
the vehicle are possible:▷Activate stationary climate control immedi‐
ately, refer to page 133.
With stationary climate control activated
and no charging cable connected, the
range is reduced.▷Planned climate control at the set depar‐
ture time, refer to page 134.
Discharged high-voltage and
vehicle battery
General information
In addition to the high-voltage battery, the ve‐
hicle has a 12 volt vehicle battery, which is re‐
quired for operation of the onboard electron‐
ics.
If the high-voltage battery and the vehicle bat‐
tery are discharged, it is not possible to oper‐
ate the vehicle.
Place vehicle in service To place the vehicle in service, charge as
usual.
If there is no possibility of charging on site,
contact the service center.
Charging vehicle with a discharged
vehicle battery
1.Unlock the vehicle, if needed, using the
integrated key, refer to page 38.2.Secure the vehicle against rolling.3.Manually unlock charging port flap if it is
locked, refer to page 163.4.Connect either a Level 1 or Level 2 charg‐
ing cable to the household socket or the
port on the charging station.5.Attach charging cable corresponding to
the charging socket connection.
Charging is started. The charging status is
not displayed. Do not open vehicle during
this time.
After several minutes, the vehicle is slightly
charged. The onboard electronics are ready
again. It is again possible to open the vehicle.
The charging status as well as the charging
state of the high-voltage battery can be dis‐
played again.
Continue charging vehicle until desired range
is possible.
If the vehicle battery cannot be charged, con‐
tact the service center.

Mobility SystemThe concept
With the Mobility System, minor tire damage
can be sealed quickly to enable continued
travel. To accomplish this, sealant is pumped
into the tires, which seals the damage from the
inside.
The compressor can be used to check the tire
inflation pressure.
Hints▷Follow the instructions on using the Mobi‐
lity System found on the compressor and
sealant container.▷Use of the Mobility System may be ineffec‐
tive if the tire puncture measures approx.
1/8 in/4 mm or more.▷Contact the nearest service center if the
tire cannot be made drivable.▷If possible, do not remove foreign bodies
that have penetrated the tire.▷Pull the speed limit sticker off the sealant
container and apply it to the steering
wheel.▷The use of a sealant can damage the TPM
wheel electronics. In this case, have the
electronics checked at the next opportu‐
nity and have them replaced if needed.
Storage
The mobility system is located in the storage
compartment under the hood.
Sealing container▷Sealing container, arrow 1.▷Filling hose, arrow 2.

Filling the tire with sealant1.Shake the sealing container.2.Take the connection hose completely out
of the compressor housing. Do not kink the
hose.3.Attach the connection hose to the connec‐
tor of the sealing container, ensuring that it
engages audibly.4.Slide the sealing container upright into the
holder on the compressor housing, ensur‐
ing that it engages audibly.5.Screw the connection hose onto the tire
valve of the defective wheel.6.With the compressor switched off, insert
the plug into a power socket inside the ve‐
hicle.Seite 179Wheels and tiresMobility179

4.Insert the connector into a power socket
inside the vehicle.5.Correct the tire inflation pressure to
2.5 bar.▷Increase pressure: with operating read‐
iness or drive readiness switched on,
reel on the compressor.▷To reduce the pressure: press the but‐
ton on the compressor.
Continuing the trip
Do not exceed the maximum permissible
speed of 50 mph/80 km/h.
Reinitialize the Flat Tire Monitor.
Reinitialize the Tire Pressure Monitor.
Replace the defective tire and the sealant con‐
tainer of the Mobility System as soon as possi‐
ble.
Snow chains Fine-link snow chains
Only certain types of fine-link snow chains
have been tested by the manufacturer of the
vehicle, classified as road-safe and approved.
Information about the approved snow chains
are available from the service center.
Use
Use only in pairs on the rear wheels, equipped
with the tires of the following size:
▷155/70 R 19Follow the snow chain manufacturer's instruc‐
tions.
Make sure that the snow chains are always
sufficiently tight. Retighten as needed accord‐
ing to the chain manufacturer's instructions.
Do not initialize the Flat Tire Monitor after
mounting snow chains, as doing so may result
in incorrect readings.
Do not initialize the Tire Pressure Monitor after
mounting snow chains, as doing so may result
in incorrect readings.
When driving with snow chains, briefly activate
Dynamic Traction Control if needed.
Maximum speed with snow chains Do not exceed a speed of 30 mph/50 km/hwhen using snow chains.Seite 181Wheels and tiresMobility181

Note Socket for Onboard Diagnosis
The socket for onboard diagnostics may
only be used by the service center or a work‐
shop that operates in accordance with the
specifications of the vehicle manufacturer with
correspondingly trained personnel and other
authorized persons. Otherwise, use may result
in operating problems for the vehicle.◀Position
Located on the driver's side is an OBD socket
for reading the vehicle data. On vehicles with
Range Extender, additional components are
checked that are critical for its emissions mix.
Emissions
Applies to vehicles with Range Extender.
▷The warning lamp lights up:
Emissions are deteriorating. Have
the vehicle checked as soon as
possible.▷The warning lamp flashes under certain
circumstances:
This indicates that there is excessive mis‐
firing in the engine.
Reduce the vehicle speed and have the
