driver.
●
When driving in a very sporty style.

In adverse weather conditions, e.g. in case
of snow or heavy rain.

WARNING
The smart technology incorporated into Traf-
fic Jam Ass
ist cannot defy the laws of phys-
ics; it only works within the limits of the sys-
tem. Accidents and severe injury may occur if
Traffic
Jam Assist is used negligently or invol-
untarily. 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 condi-
tions.
●
Do not use Traffic Jam Assist in city jour-
neys.
●
Do not use Traffic Jam Assist if there is poor
visibility, for example, in case of snow, ice,
rain or loose gravel, or on steep or slippery
sections or flooded roads.
●
Do not use Traffic Jam Assist offroad or on
roads where the surface is not firm. Traffic
Jam Assist has been designed for use on
paved roads only.
●
Traffic Jam Assist does not react to people
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 immediately 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 con-
trol 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 driv-
ing (accelerating or braking) yourself.
Note
●
If
T
raffic Jam Assist does not work as de-
scribed in this chapter, stop using it and con-
tact a specialised workshop.
●
If the system is faulty, take it to a special-
ised workshop and have it checked.
Emergency Assist
D
e
s
cription and operation
Emergency Assist detects whether there is in-
activ
ity
b
y the driver and can automatically
keep the car within the lane and stop it alto-
gether if necessary. This way the system can
actively help avoid an accident.
Emergency Assist is an additional function of
Lane Assist ››› page 230 and combines Lane
Assist functions with Adaptive Cruise Control
(ACC) ››› page 221. Therefore, it is essential
that you read these two chapters carefully
and note the limitations of the systems and
the information about them.
