Proactive Speed Adjustment - Seat Leon Owner's Manual

Narrow or misaligned vehicles
The radar sensor can only detect narrow ve-
hicles or vehicles that circulate out of align-
ment when they enter its range
In these cases, you should brake as necessa-
ry.
Vehicles with special loads and accesso-
ries
Special loads and accessories of other vehi-
cles that jut out over the sides, backwards or
over the top may be out of the ACC's range.
SEAT recommends disconnecting it.
Other vehicles changing lanes
Vehicles changing lanes a short distance
away from your own can only be detected
when they are within range of the sensors. As
a consequence, the ACC will take longer to

react Fig. 168 . Brake yourself as neces-

sary.
Stationary vehicles
The ACC does not detect stationary vehicles,
such as traffic jam tails or broken down vehi-
cles.
If a vehicle detected by the ACC turns or
moves over and there is a stationary vehicle
in front of it, the ACC will not react to it

Metal objects
Metal objects, e.g. guard rails or sheets used
in road works, can confuse the radar sensor
and cause the ACC to react wrongly.
Factors that may affect how the radar
sensor operates
If radar sensor operation is impaired due to
heavy rain, mist, snow, mud, dust, insects, etc.,
the ACC is deactivated temporarily. A mes-
sage will be displayed stating this. If necessa-
ry, clean the radar sensor
When the radar sensor begins to operate
properly, the ACC will become available. The
message will turn off and the ACC may be
reactivated.
ACC operation may be affected by a strong
radar reverse reflection, for example in a
closed car park. SEAT recommends discon-
necting it.
Trailer mode
When driving with trailer the ACC controls
less dynamically.
Driving
Overheated brakes
If the brakes overheat, for example on long
and steep descents, the ACC may be deacti-
vated temporarily. A message will be dis-
played stating this. In this case, adaptive
cruise control cannot be activated.
Cruise control may be reactivated once the
brake temperature has dropped. The mes-
sage will disappear. If the message ACC not
available
means that there is a fault. Contact a speci-
alised workshop. SEAT recommends visiting a
SEAT dealership.

Proactive speed adjustment

The proactive speed adjustment adapts the
speed to the speed limitations detected and
remains on for quite a long time it
WARNING
If you do not pay attention to the Press
message, the vehicle may move
the brake
and crash into the vehicle ahead. Before
driving off again, check that the road is
clear. The radar sensor may not detect ob-
stacles on the road. This could cause an
accident and serious injuries. If necessary,
apply the brake.
