Charge cord9 Danger
There is a risk of electric shock
that may cause personal injury or
death.
Do not use the charge cord if any part of the charge cord is
damaged.
Do not open or remove the charge cord cover.
Service by qualified personnel
only. Connect the charge cord to a
properly grounded outlet with
cords that are not damaged.
200Driving and operating
A portable charge cord used to
charge the vehicle high voltage
battery is stored under the rear floor
storage cover in the load
compartment 3 195 . The charge cord
is compatible with the domestic
electrical outlet of the respective
country. It includes a control box with
charging status indicators.
If the vehicle is to be used abroad,
check whether the wall plug of the
charge cord is compatible with the
local electrical outlets. If a different
charge cord is needed, consult a
workshop.
Important information about
portable electric vehicle charging
● Charging an electric vehicle can stress a building's electrical
system more than a typical
household appliance.
● Before you plug in to any electrical outlet, have a qualified
electrician inspect and verify the
electrical system (electrical
outlet, wiring, junctions and
protection devices) for heavy-
duty service at a 10 A continuous
load.
● Electrical outlets may wear out with normal usage or be
damaged over time, making them unsuitable for electric vehicle
charging.
● Check the electrical outlet / plug while charging and discontinue
use if the electrical outlet / plug is
hot, then have the electrical
outlet serviced by a qualified
electrician.● When outdoors, plug into an electrical outlet that is weather-
proof while in use.
● Mount the charging cord to reduce strain on the electricaloutlet / plug.9 Warning
Improper use of portable electric
vehicle charge cords may cause a fire, electrical shock, or burns, and
may result in damage to property,
serious injury, or death.
● Do not use extension cords, multi-outlet power strips,
splitters, grounding adaptors,
surge protectors, or similar
devices.
● Do not use an electrical socket that is worn or damaged, or onethat will not hold the plug firmly
in place.
● Do not immerse the charging chord into any liquid.
Driving and operating201● Do not use an electrical socketthat is not properly grounded.
● Do not use an electrical socket that is on a circuit with other
electrical loads.9 Warning
Read all the safety warnings and
instructions before using this
product. Failure to follow the
warnings and the instructions may result in electric shock, fire, and /
or serious injury.
Never leave children unattended
near the vehicle while the vehicle is charging and never allow
children to play with the charge
cord.
If the plug provided does not fit the electrical outlet, do not modify the
plug. Arrange for a qualified
electrician to inspect the electrical
outlet.
Do not put fingers into the electric
vehicle connector.

Charge cord status indicators
After plugging in the charge cord, it
will perform a quick self test and all
status indicators come on for a
moment. Verify the status:
● ! Power
Illuminates yellow: Connection
has been established. The
charge cord is ready to charge
the vehicle.
● 7 Charge
Illuminates green: Charging is
complete.
Flashes green: High voltage
battery is not fully charged.
Charging process is going on or programmable charging is active.
● + Fault
Illuminates red: Fault.
Check whether the connections
to the charge port and to the
electrical outlet are correct. Make
sure that the electrical installation and the charge cord are not
damaged.
If no status indicator comes on, verify the circuit breaker of the electrical
outlet:
● If the circuit breaker has broken, contact a qualified electrician to
verify the compatibility of the electrical installation and repair it.
● If the circuit breaker has not broken, the charge chord may bedefective. Do not use the charge
chord and contact a workshop.
Vehicle care217Caution
Only washer fluid with a sufficient
antifreeze concentration provides
protection at low temperatures or
a sudden drop in temperature.
Washer fluid 3 255.
Brakes In the event of minimum thickness of
the brake lining, a squealing noise
sounds during braking.
Continued driving is possible but
have the brake lining replaced as
soon as possible.
Once new brake linings are installed,
do not brake unnecessarily hard for
the first few journeys.
Brake fluid
9 Warning
Brake fluid is poisonous and
corrosive. Avoid contact with eyes,
skin, fabrics and painted surfaces.
The brake fluid level must be betweenthe DANGER and MAX marks.
If fluid level is below DANGER seek
the assistance of a workshop.
Brake and clutch fluid 3 255.
Vehicle battery
The vehicle battery is maintenance-
free provided that the driving profile
allows sufficient charging of the
battery. Short-distance-driving and
frequent engine starts can discharge
the battery. Avoid the use of
unnecessary electrical consumers.
Batteries do not belong in household
waste. They must be disposed of at
an appropriate recycling collection
point.
Laying up the vehicle for more than
four weeks can lead to battery
discharge. Disconnect the clamp from the negative terminal of the vehicle
battery.
Ensure the ignition is switched off
before connecting or disconnecting
the vehicle battery.
Battery discharge protection 3 122.
Replacing the vehicle battery Note
Any deviation from the instructions
given in this section may lead to
temporary deactivation or
disturbance of the stop-start system.
218Vehicle careWhen the vehicle battery is beingreplaced, please ensure that there
are no open ventilation holes in the
vicinity of the positive terminal. If a
ventilation hole is open in this area, it
must be closed off with a dummy cap, and the ventilation in the vicinity of the
negative terminal must be opened.
Ensure that the battery is always
replaced by the same type of battery.
The vehicle battery has to be
replaced by a workshop.
Stop-start system 3 139.
Charging the vehicle battery9 Warning
On vehicles with stop-start
system, ensure that the charging potential does not exceed 14.6 V
when using a battery charger.
Otherwise the vehicle battery may be damaged.
Jump starting 3 244.
Discharge protection
Battery voltage
When the vehicle battery voltage is
running low, a warning message will
appear in the Driver Information
Centre.
When the vehicle is being driven, the
load reduction function temporarily
deactivates certain functions, such as
the air conditioning, the heated rear
window, heated steering wheel, etc.
The deactivated functions are
reactivated automatically as soon as
conditions permit.
Idle boost
If charging of the vehicle battery is
required due to battery condition, the
power output of the generator must
be increased. This will be achieved by
an idle boost which may be audible.
A message appears in the Driver
Information Centre.
Power outlet
The power outlets are deactivated in
the event of low vehicle battery
voltage.Warning label
Meaning of symbols:
● No sparks, naked flames or smoking.
● Always shield eyes. Explosive gases can cause blindness or
injury.
● The vehicle battery contains sulphuric acid which could cause
blindness or serious burn
injuries.
● Keep the vehicle battery out of reach of children.
Vehicle care219● See the Owner's Manual forfurther information.
● Explosive gas may be present in the vicinity of the vehicle battery.
Power saving mode
This mode deactivates electrical
consumers to avoid excessive
discharging of the vehicle battery.
These consumers, such as the
Infotainment system, windscreen
wipers, low beam headlights,
courtesy light, etc. can be used for a
total maximum time of about
40 minutes after ignition is switched
off.
Changing into power saving mode
When power saving mode is
activated, a message appears in the
Driver Information Centre.
An active telephone call using the
hands-free option will be maintained
for around 10 minutes longer.Deactivating power saving mode
Power saving mode is deactivated automatically when the engine isrestarted. Run the engine for a
sufficient charge:
● for less than 10 minutes to use the consumers for approx.
5 minutes
● for more than 10 minutes to use the consumers for up to approx.
30 minutes
Heating functionalities Note
Individual heating functionalities,
such as heated seats or heated
steering wheel, may be temporarily
unavailable in the event of electrical
loading constraints. Functions will be resumed after some minutes.Diesel fuel system bleeding
If the tank has been run dry, the diesel fuel system must be bled. Switch on
the ignition three times for
15 seconds at a time. Then crank the
engine for a maximum of 40 seconds. Repeat this process after
no less than 5 seconds. If the engine
fails to start, seek the assistance of a
workshop.
