Seats, restraints65If control indicator ÓON illuminates
after the ignition is switched on and
control indicator *OFF is not
illuminated, the front passenger
airbag system will inflate in the event
of a collision.
If both control indicators ÓON and
* OFF are illuminated
simultaneously, there is a system
failure. The status of the system is not
discernible, therefore no person is
permitted to occupy the front
passenger seat. Contact a workshop immediately.
If control indicator F 3 98
illuminates together with v 3 97,
this indicates a fault within the
system. The switch position may have been changed inadvertently with the
ignition on. Turn ignition off and on
again and reset the switch position. If
F and v still remain illuminated, seek
the assistance of a workshop.
Change status only when the vehicle
is stopped with the ignition off. Status remains until the next change.

Child restraint systems9 Danger
If using a rear-facing child restraint
system on the front passenger
seat, the airbag system for the
front passenger seat must be
deactivated. This also applies to certain forward-facing child
restraint systems as indicated in
the table 3 68.
Airbag deactivation 3 64.
Airbag label 3 59.
We recommend a child restraint system which is tailored specifically to the vehicle. For further information,
contact your workshop.
When a child restraint system is being
used, pay attention to the following
usage and installation instructions
and also those supplied with the child
restraint system.
Always comply with local or national
regulations. In some countries, the
use of child restraint systems is
forbidden on certain seats.
Child restraint systems can be
fastened with:
● Three-point seat belt
● ISOFIX brackets
● Top-Tether
Three-point seat belt
Child restraint systems can be
fastened by using a three-point seat
belt 3 56.
Depending on the size of the used
child restraint systems and the model
variant, child restraint systems can be
attached to certain 2nd row and 3rd
row rear seats 3 68.
ISOFIX brackets ISOFIX mounting brackets are
indicated by the ISOFIX logo or
symbol on the seat cushion.

Connecting electrical accessories while the engine is off will discharge
the vehicle battery. Do not exceed the
maximum power consumption of
120 watts.9 Danger
To avoid the risk of fire, if multiple
power outlets are used
simultaneously, the total power
consumption of connected
accessories must not exceed
180 watts.
With ignition off the power outlet may
be deactivated.
Additionally, the power outlet may be
deactivated in case of low battery
voltage.
Electrical accessories that are
connected must comply with the
electromagnetic compatibility
requirements laid down in
DIN VDE 40 839.

Speed limiter Maximum speed may be restricted by
a speed limiter. As a visible indication
of this, a warning label is located on
the instrument panel.
A warning buzzer will sound for
ten seconds every 40 seconds if the
vehicle briefly exceeds the set limit.
Note
Under certain conditions (e.g. steep
inclines), the vehicle speed may
exceed the set limit.

Note
To ensure the fuel level is displayed
correctly, the ignition must be
switched off before refuelling. Avoid
minor fuel top-ups (e.g. less than
five litres) to ensure accurate
readings.
Because of the fuel remaining in the
tank, the top-up quantity may be less
than the specified tank capacity.

The current AdBlue percentage
remaining can be shown in the Driver
Information Centre 3 102.

Fuel economy gauge
Depending on version, the fuel
economy gauge (or 'driving style
indicator') provides an instantaneous
calculation of fuel efficiency based on
current driving style.
The gauge uses colours to indicate
current fuel efficiency:
Green:best fuel economy is being achievedYellow:driving style too
aggressiveOrange:least efficient fuel
economyThe fuel economy gauge is enabled
by default.
Depending on version, the fuel
economy gauge (or 'driving style
indicator') can be disabled via the
