Introduction
Introduction
This Owner's Manual supplement
provides all the necessary
information about the fuel cell
version.
It is only valid in combination
with the Owner's Manual for your
vehicle and cannot be considered
separately.
General information The vehicle uses a mid-power
hydrogen fuel cell system that is
supported by a high voltage battery,
in order to provide sufficient
autonomy. The fuel cell drivetrain contains of
three subsystems:
● The
fuel cell system (1) located in
the engine compartment.
● The high voltage battery (2) located under the front seats.
● The hydrogen tank system (3) located under the load
compartment.
The hydrogen reacts in the fuel cell
with oxygen supplied from the
ambient air. Water, heat and
electrical energy emerge from this
reaction.
Water and excess air are released
through the exhaust, while the
electrical energy is used to provide
the electric motor with power.
Additionally to that, the high voltage
battery can be charged via a charging
port in order to guarantee sufficient
autonomy in case of an empty
hydrogen level. Electric energy is also
provided by regenerative braking.CarM an uals 2 .c o m

As
required by European regulations,
this table gives the options for
installing child seats secured using
the seat belt and universally
approved as well as the larger ISOFIX
and i-Size child seats on seat
positions equipped with ISOFIX
mountings in the vehicle.
Yes : Suitable for fitment of the designated catecory of the
child restraint system.
No : Not suitable for fitment of the designated catecory of the
child restraint system.CarM an uals 2 .c o m

Universal child seat: chiId seat that can be installed in all vehicles using the seat belt. Applies to all stature and mass groups.
2) For a seat with height adjustment, set it to the highest and fully back longitudinal position.
3) Only a forward facing child restraint system is authorised at this seat position with the front passenger's airbag activated ON.
4) To install a rearward facing child restraint system at this seat position, the front passenger's airbag must be deactivated OFF.
5) Seat not fitted with ISOFIX compliant mountings.
6) Set the headrest to the lowest position.CarM an uals 2 .c o m

Hydrogen leakage
u illuminates red together with C
and a warning message is displayed
in the Driver Information Centre.
A hydrogen leak has been detected.
Do not park or transport the vehicle
indoors,
such as a garage or the like. 9
Warning Have the cause of the fault
remedied immediately by a
workshop. Fuel cell system fault
v and C are illuminated yellow
and a warning message is displayed
in the Driver Information Centre.
The range of the vehicle might be
reduced. In order to enable the
continuation of the journey, the high
voltage battery will be used.
Therefore, ensure that the charging
level
of the high voltage battery is high
enough.
Seek the assistance of a workshop.
Charging 3 14. Displays
Driver Information Centre Combined autonomy information
menu The combined autonomy (fuel cell
system and high voltage battery) of
the vehicle is shown in this menu.
The autonomy is calculated from
current hydrogen level, the charging
level of the high voltage battery and
from the current consumption. The
display shows average values. After refuelling or charging, the range
is updated automatically after a brief
delay.
