Situations where traffic jam assist has to
be disconnected
Due to the limitations of the system, Traffic
Jam Assist must always be switched off in the
following situations:
●
When more attention is required by the
driver.
●
When driving in a very sporty style.
●
In adverse weather conditions, e.g. in case
of snow or heavy rain.
●
When driving on roads in poor condition.
●
In sections with roadworks.
●
In city journeys.
WARNING
The smart technology incorporated into
Traffic Jam Assist cannot defy the laws of
physics; it only works within the limits of the
syst
em. Accidents and severe injury may
occur if Traffic Jam Assist is used negli-
gently or involuntarily. The system is not a
replacement for driver awareness.
●
Adapt your speed and safe distance to
the vehicle in front of you at all times to suit
the visibility, weather, road and traffic con-
ditions.
●
Do not use Traffic Jam Assist in city jour-
neys.
●
Do not use T
raffic Jam Assist if there is
poor visibility, for example, in case of snow,
ice, rain or loose gravel, or on steep or slip-
pery sections or flooded roads.
●
Do not use Traffic Jam Assist offroad or
on roads where the surface is not firm. Traf-
fic Jam Assist has been designed for use on
paved roads only.
●
Traffic Jam Assist does not react to peo-
ple or animals or vehicles crossing your
path or that approach you head-on down
the same lane.
●
If Traffic Jam Assist does not reduce
speed sufficiently, brake the vehicle imme-
diately by applying the pedal.
●
If the vehicle continues to move when you
wish it to stop after a driver intervention
prompt, brake the vehicle by applying the
pedal.
●
If driver intervention is requested on the
dash panel display, immediately resume
control of the vehicle.
●
Keep your hands on the wheel at all times
to be ready to intervene in the steering at
any time. The driver is always responsible
for keeping the vehicle in its own lane.
●
Always be prepared to take charge of
driving (accelerating or braking) yourself.
Note
●
If Traffic Jam Assist does not work as de-
scribed in this chapter
, stop using it and
contact a specialised workshop.
●
If the system is faulty, take it to a special-
ised workshop and have it checked.

that you read these two chapters carefully
and note the limitations of the systems and
the information about them.
