Driver assistance systems
Narrow or misaligned vehicles
The r
adar sensor can only det
ect narr
ow or
misaligned vehicles when they are within
range
››
Fig. 275 B. This applies particularly
to narrow vehicles such as motorbikes. In
these cases, you should brake as necessary.
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.
Switch off the ACC when driving behind vehi-
cles with special loads and accessories or
when overtaking them. In these cases, you
should brake as necessary.
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.
Consequently, the ACC will take longer to re-
act
››
Fig. 276 C. In these cases, you should
brake as necessary.
Stationary vehicles
The ACC does not detect stationary objects
while driving, such as traffic tails or damaged
vehicles.
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
››
Fig. 276 D. In these cases, you should
brake as necessary.
Vehicles driving in the opposite direction
and vehicles crossing your path
The ACC does not react to vehicles ap-
proaching from the opposite direction or ve-
hicles crossing your path.
Metal objects
Metal objects, e.g. rails on the road 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 laser sensor operation is impaired, due to
heavy rain, spray, snow or mud, the ACC is
deactivated temporarily. The relevant text
message will appear in the dash panel dis-
play. If necessary, clean the radar sensor.
When the radar sensor begins to operate
properly again, the ACC will automatically
be available again. The message on the in-
strument panel screen will switch off and the
ACC will be reactivated again.
ACC operation may be affected by a strong
radar reverse reflection, for example in a
closed car park.
Trailer mode
When driving with trailer the ACC controls
less dynamically.
Overheated brakes
If the brakes overheat, for example after
abrupt braking or in long and steep slopes,
the ACC may be deactivated temporarily.
The relevant text message will appear in the
dash panel display. In this case, adaptive
cruise control cannot be activated.
Adaptive Cruise Control can be reactivated
once brake temperature has cooled suffi-
ciently. The message will disappear from the
instrument panel display. If the message ACC
not available remains on for quite a long
time it means that there is a fault. Contact a
specialised workshop. SEAT recommends vis-
iting a SEAT dealership.
WARNING
If you do not heed the Press the brake
message, the vehicl
e may initiate an invol-
untary movement and could crash into the
vehicle ahead. In any event, before driving
off, check that the road is clear. The radar
sensor may not detect obstacles on the
road. This could cause an accident and se-
rious injuries. If necessary, apply the brake.
