°C.
Vehicle
operation is restricted to this
ambient temperature range.
Parking Note

Charging
General information Electric power consumption and
rangeThe electric power consumption and
the vehicle's range by using only the
high voltage battery were not
available at time of printing.
For the values specific to your
vehicle,
refer to the EEC Certificate of
Conformity provided with your vehicle
or other national registration
documents.
The determination of electric power
consumption is regulated by directive
R (EC) No. 715/2007 and No.
2017/1151 (in the latest applicable
version).
Charging
In order to ensure the compatibility of
plug and outlet, different labels are
used. The labels are located on the
inside of the vehicle's charging port
flap. Make sure to connect only a
cable of the same type. Type 2 plug or outlet used for AC
charging
Note
The system does not allow the
simultaneous refuelling and
charging of the vehicle. Fuel
Hydrogen Only use hydrogen fuel that complies
with European standards DIN EN
17124 or ISO 14687 or equivalent. A label with symbols at the fuel filler
flap is indicating the allowed
hydrogen fuel type, as well as the
maximum
fueling pressure (MFP) and
the nominal working pressure (NWP).
In Europe the pump nozzles of the
filling stations are marked with these
symbols. Refuel only the allowed fuel type.CarM an uals 2 .c o m

Expiring date hydrogen tanks 9
Danger Never refuel the hydrogen tanks
after the indicated expiring date.
The expiring date of the hydrogen
tanks is indicated on a label located
on the inside of the fuel filler flap.
Refuelling 9
Danger Before refuelling, switch off
ignition and any external heaters
with combustion chambers.
Follow the operating and safety
instructions of the filling station
when refuelling. 9
Danger Never refuel the vehicle after an
accident.
Seek the assistance of a
workshop. 9
Warning Only use fueling stations which
comply with the fueling standard
SAE J2601 or EN 17127.
Note
The system does not allow the
simultaneous refuelling and
charging of the vehicle.
Note
Once
refuelling has been enabled by
the system, the refuelling of the
vehicle must be started within five
minutes. If this time has been
expired, the refuelling process is
cancelled.
In this case, close the fuel filler flap,
if it has been opened before, and
start refueling process again. Before refuelling
In order to start the refuelling,
following preconditions must be
fullfilled:
●
The vehicle is stationary.
● The ignition is switched off.
● The parking brake is applied.
● The gear selector is in position P.
Refuelling 1. Press r. The system performs a
check of the preconditions. This
may take up to 30 seconds. If the
preconditions have been fullfilled,CarM an uals 2 .c o m

the fuel filler flap is then unlocked
and a message is displayed in the
Driver Information Centre. 2. Open the fuel filler flap by pulling
on the right bottom corner.
Note
If the fuel filler flap has been closed
again by mistake, it has to be re-
opened
within one minute, otherwise
the refueling process needs to be
started again.
The fuel filler flap is located at leftrear side of the vehicle. 3. Remove the fuel filler cap and
refuel the vehicle by following the
instructions given by the filling
station.
4.
After refuelling, reinsert the fuel
filler cap, close the fuel filler flap

Fuel cell system coolant Coolant level Caution
The coolant reservoir may contain
traces of hydrogen which is
normal.
Using the wrong coolant can
cause
severe damages to the fuel
cell system. Only trained service
personnel are allowed to open the
coolant reservoir and to top up
coolant. Caution
A too low coolant level can cause
damage to the fuel cell system. If the cooling system is cold, the
coolant level should be above the
MIN mark. If the cooling level is too
low, seek the assistance of a
workshop.
Engine coolant
The factory filled coolant provides
freeze protection down to approx.
-37 °C
. Caution
Only use approved antifreeze.CarM an uals 2 .c o m

Coolant level Caution
A too low coolant level can cause
engine damage.
If the cooling system is cold, the
coolant level should be above the
MIN mark. Top up if the level is low. 9
Warning Allow the engine to cool before
opening the cap. Carefully open
the cap, relieving the pressure
slowly.
To top up, use a 1:1 mixture of
released coolant concentrate mixed
with clean tap water. If no coolant
concentrate is available, use clean
tap
water. Install the cap tightly. Have
the coolant concentration checked
and have the cause of the coolant
loss remedied by a workshop. Electrical system
Fuses
Data on the replacement fuse must
match
the data on the defective fuse.
There is a fuse box in the engine
compartment.
Before replacing a fuse, turn off the
respective switch and the ignition.
A blown fuse can be recognised by its melted wire. Caution
Do not replace the fuse until the
cause of the fault has been
remedied.
Some functions are protected by
several fuses.
Fuses may also be inserted without
existence of a function.
