2016 Seat Mii lane assist

Driver assistance systems
assumes the responsibility of braking in
time.
●
The City Safety Assist function cannot pre-
vent ac
cidents or serious injury by itself.
● The City Safety Assist system may carry out
unw
anted brake interventions in complex
driving situations e.g. when a vehicle crosses
at a short distance. WARNING
Relying on the City Safety Assist system in
c ity driv

ing as part of one's driving behaviour
may cause accidents and serious injury. The
system is not a replacement for driver aware-
ness.
● Always adapt your speed and the distance
to the v
ehicles ahead in line with visibility,
weather conditions, the condition of the road
and the traffic situation.
● The City Safety Assist function does not re-
act to peop
le, animals or vehicles that cross
or move in the opposite direction in the same
lane.
● If after switching on the City Safety Assist
function the
vehicle begins to move, slow the
vehicle with the foot brake. CAUTION
If you suspect that the City Safety Assist la-
ser fe at

ure is damaged, disconnect it. This
will avoid additional damage. ●
Any r

epair of the laser sensor requires spe-
cialised skills. SEAT recommends taking your
car in for technical service. Note
● If the C ity

Safety Assist function activates a
brake, the brake pedal range is reduced. This
makes the brake pedal seem “harder”.
● Automatic brake intervention by the City
Safety As
sist function can be cancelled by
pressing the clutch pedal, the accelerator
pedal or by a corrective intervention.
● During automatic braking by the City Safety
Assi
st function you may hear unusual noises.
This is normal and is produced in the brake
system. Warning and control lamp

● While the vehicle is being towed. ●
If the

● If the vehicle is above a test bed.
● If the laser sensor is defective.
● After the laser sensor has been involved in
a col
lision.
● When driving off road (overhanging branch-
es).
● If o

bjects are protruding above the bonnet,

Operation
The City Safety Assist function is limited by
the l a
w
s of physics and by the nature of the
system itself. For this reason, this may pro-
duce reactions from the City Safety Assist
system in certain circumstances that are late
or unexpected by the driver. For this reason,
always pay due attention and if necessary, in-
tervene.
For example, the following driving situations
require special attention:
Driving through a bend
When entering or leaving a “long” bend, the
vehicle may decelerate when the laser sensor
detects a vehicle travelling in the adjoining
lane ››› Fig. 156 A. To interrupt deceleration
you can accelerate, turn the steering wheel or
press the clutch.
Narrow vehicles in front
The laser sensor will only detect narrow vehi-
cles in front if they are in the sensor detec-
tion zone ››› Fig. 156 B. This applies especial-
ly to narrow vehicles such as motorbikes.
Other vehicles changing lanes
Vehicles moving into your lane in close prox-
imity can cause unexpected braking from the
City Safety Assist system ›››
Fig. 157. To inter-
rupt deceleration you can accelerate, turn the
steering wheel or press the clutch. Possible malfunction to the laser sensor
If the la
ser sensor operation function is im-
paired, for example due to heavy rain, mist,
snow or dirt, the City Safety Assist system
function is temporarily disconnected. On the
instrument panel display the control lamp 
flashes.
When the malfunction in the laser sensor has
been rectified, the availability of the City
Safety Assist system function is automatically
restored. The control lamp  switches off.
The following conditions could prevent the
City Safety Assist system from functioning:
● Tight bends.
● Accelerator pressed all the way down to the
floor.
● If the C

ity Safety Assist system is switched
off or there i
s a fault ››› page 157.
● If the laser sensor is dirty, covered or over-
heated ›

›› page 158.
● In the event of snow, heavy rain or dense
fog.
● If ther

e are vehicles in front.
● Vehicles changing lanes.
● Vehicles moving in the opposite direction
in the same lane.
● V

ery dirty vehicles with a low degree of re-
flection.
● Pr e

sence of thick dust. Hill driving assistant*
Operation This function is only included in vehicles with
ESC.
The hi l

l driving assistant helps the driver to
move off and upward on a hill when the vehi-
cle is stationary.
The system maintains brake pressure for ap-
proximately two seconds after the driver
takes his foot off the brake pedal to prevent
the vehicle from lurching backward when it is
started. During these 2 seconds, the driver
has enough time to release the clutch pedal
and accelerate without the vehicle moving
and without having to use the handbrake,
making start-up easier, more comfortable
and safer.
These are the basic operation conditions:
● being on a ramp or hill/slope,
● doors closed,
● vehicle completely stationary,
● engine running and foot on the brake,
● besides having a gear engaged or being in
neutral f

or manual gear change and with the
selector lever at positions S, D or R in vehi-
cles with an automatic gearbox.
This system is also active when reversing up-
hill.
