terior temperature.
It is possible to select interior temperatures
from +16°C (+64°F) to +29°C (+84°F). In this range the temperature is regulated automati-
cal
ly

. If a temperature below +16°C (+64°F) is
selected, “LO” is displayed on the screen. If a
temperature above +29°C (+84°F) is selected,
“HI” is displayed on the screen. At both ex-
tremes, Climatronic works at maximum cool-
ing or heating power, respectively. The tem-
perature is not regulated.
In the event of prolonged, irregular distribu-
tion of the air flow from the outlets (particu-
larly the footwells) and significant differen-
ces in temperature, e.g. on leaving the vehi-
cle, sensitive people may catch cold.

after the engine stops, you will only have 5
seconds to restart it. A warning will display
on the dash panel screen.
After this interval, it will not be possible to
start the engine without a valid key inside
the vehicle.
Automatic deactivation of the ignition on ve-
hicles with the Start-Stop system
The ignition is switched off automatically
when the vehicle is stopped and the auto-
matic engine shutdown is active, if:
● The driver's seat belt is not fastened,
● the driver does not step on any pedal, ●
the driver door is
opened.
After automatically turning off the ignition, if
the dipped beam  is on, the side light re-
mains on for approx. 30 minutes (if the bat-
tery is sufficiently charged). If the driver locks
the vehicle or manually turns off the light, the
side light goes out. WARNING
Any accidental movement of the vehicle could

ABS and ASR.
Connecting/disconnecting ESC and
ASR*
The ESC is switched on automatically when
the engine i
s
started, and only works when
the engine is running and includes the ABS,
EDS and ASR systems.
The ASR and ESC function should only be
switched off in situations in which traction is
insufficient, among others:
● When driving in deep snow or on surfaces
that ar

e not very firm.
● To “free” the vehicle if it gets stuck.
Then switc
h the ASR and ESC function back

Depending on finishes and versions, it is
possible either to disconnect only the ASR or
else activate ESC Sport mode.
ESC in “Sport” mode
Sport mode can be connected via the Easy
Connect ››› page 118 system menu. The ESC
and the traction control system (ASR) have
only a limited ability to stabilise the vehicle.
The control lamp  lights up. For vehicles
with a driver information system*, the driver will be shown the
electronic stability

››› page 118. The warning lamp  will switch
off. For vehicles with a driver information sys-
tem*, the driver will be shown the elec-
tronic stability control (ESC)
option: on.
Disable ASR
The Easy Connect system menu is used to

System function buttons. WARNING
You should switch on the ESC Sport mode on-
ly if the tr

affic conditions and your driving
ability allow you to do so safely: risk of skid-
ding!
● With ESC in Sport mode, the stabilising
function w
ill be limited to allow for a sportier
drive. The driving wheels could spin and the
vehicle could skid. Note
If the ASR is disconnected or the ESC’s Sport
mode is sel

ected, cruise control* will be
switched off. Electronic differential lock (EDS)*
The EDL operates along with the ABS in vehi-
c
l
e

s equipped with Electronic Stability Con-
trol (ESC)*.
EDL helps the vehicle to start moving, accel-
erate and climb a gradient in slippery condi-
tions where this may otherwise be difficult or
even impossible.
It uses the ABS sensors to monitor the speed
of the driven wheels.
At speeds of up to approximately 80 km/h
(50 mph), it is able to balance out differences
in the speed of the driven wheels of approxi-
mately 100 rpm/min caused by a partially
slippery road surface. It does this by braking »

Driving
a deliberate warning to the driver that one or
mor e of
the wheel
s is tending to lock and the
ABS control function has intervened. In this
situation it is important to keep the brake
pedal fully depressed so the ABS can regu-
late the brake application. Do not “pump”.
If you brake hard on a slippery road surface,
the best possible control is retained as the
wheels do not lock.
However, ABS will not necessarily guarantee
shorter braking distances in all conditions.
Braking distance could even be further if you
brake on gravel or on fresh snow on a slip-
pery surface.
Control lamp
The control lamp  lights up for a few sec-
onds when the ignition is switched on. It
goes out again after the system has run
through an automatic test sequence.
There is a fault in the ABS if:
● The control lamp  does not
light up when
the ignition is switched on.
● The control lamp does not go out again af-
ter a few sec
onds.
● The control lamp lights up when the vehicle
is mo
ving.
The vehicle can still be braked in the normal
way, without the ABS function. Take the vehi- cle to a specialised workshop as soon as
poss

ible.
If there is a fault in the ABS, the ESC* and the
tyre pressure control lamp will also light up.
Brake system fault
If the ABS warning lamp  lights up together
with the brake warning lamp , there is a
fault in the ABS function and in the brake
system ››› .
WARNING
● The anti-lock br

ake system cannot defy the
laws of physics. Slippery and wet roads are
dangerous even with ABS! If you notice that
the ABS is working (to counteract locked
wheels under braking), you should reduce
speed immediately to suit the road and traffic
conditions. Do not let the extra safety fea-
tures tempt you into taking any risks when
driving.
● The effectiveness of ABS is also determined
by the ty
res fitted ››› page 278.
● If the running gear or brake system is modi-
fied, the effectivene
ss of the ABS could be se-
verely limited. WARNING
● Bef or

e opening the bonnet, read and ob-
serve the warnings ››› page 267, Working in
the engine compartment. ●
If the br ak

e system warning lamp  should
light up together with the ABS warning lamp
 , stop the vehicle immediately and check
the brake fluid level in the reservoir
››› page 275, Brake fluid. If the brake fluid
level has dropped below the “MIN” mark you
must not drive on. Risk of accident. Obtain
technical assistance.
● If the brake fluid level is correct, the fault in
the brake sy
stem may have been caused by a
failure of the ABS system. This could cause
the rear wheels to lock quickly when you
brake. This could cause the rear to break
away. Risk of skidding. Stop the vehicle and
seek technical assistance. Electronic differential lock (XDS)*
When taking a curve, the driveshaft differen-
ti
al
mec

hanism allows the outer wheel to turn
at a higher speed than the inner wheel. In
this way, the wheel that is turning faster (out-
er wheel) receives less drive torque than the
inner wheel. This may mean that in certain
situations the torque delivered to the inner
wheel is too high, causing the wheels to
spin. On the other hand, the outer wheel is
receiving a lower drive torque than it could
transmit. This causes an overall loss of lateral
grip on the front axle, resulting in understeer
or “lengthening” of the trajectory.
The XDS system can detect and correct this
effect via the sensors and signals of the ESC. »

Operation
Distance warning
If the sy
s
tem detects that safety is endan-
gered by the proximity of the vehicle in front,
it may warn the driver by means of a message
on the instrument panel when driving at a
speed of between approximately 60 km/h
(37 mph) and 250 km/h (156 mph)
››› Fig. 187.
The warning moment varies depending on
the traffic situation and driver behaviour.
Advance warning
If the system detects a possible collision with
the vehicle in front, it may warn the driver by
means of an audible warning and an indica-
tion on the instrument panel when driving at
a speed of between approximately 30 km/h
(18 mph) and 250 km/h (156 mph)
››› Fig. 187.
The warning moment varies depending on
the traffic situation and driver behaviour. At
the same time, the vehicle will prepare for a
possible emergency braking ››› .
C ritic
a

l warning
If the driver fails to react to the advance
warning, the system may actively intervene in
the brakes when driving at a speed of be-
tween approximately 30 km/h (18 mph) and
250 km/h (156 mph), generating a brief jolt
to warn of the imminent collision. Automatic braking
If the driver al

so fails to react to the advance
warning, the system may brake the vehicle
automatically, by progressively increasing
braking effect driving at a speed of between
approximately 4 km/h (2.5 mph) and
250 km/h (156 mph). By reducing speed in
case of a possible collision, the system may
contribute to reducing the consequences of
an accident.
Front assist
If the Front Assist notices that the driver is
not braking sufficiently in case of a collision
hazard, the system can increase braking ef-
fect and thus avert the collision when driving
at a speed of between approximately 4 km/h
(2.5 mph) and 250 km/h (156 mph). Front
assist only acts while the brake pedal is
pressed down hard. WARNING
The intelligent technology in the Front Assist
cannot c

hange the laws of physics. The driver
is always responsible for braking in time. If
the Front Assist issues a warning, then, de-
pending on the traffic circumstances, you
must brake immediately or dodge the obsta-
cle.
● Adapt your speed and safe distance to the
vehicl
e in front of you at all times to suit visi-
bility, weather, road and traffic conditions. ●
The Front As

sist alone cannot avoid acci-
dents and serious injuries.
● In complex driving situations, the Front As-
sis
t may issue unnecessary warnings and in-
tervene unnecessarily in braking, such as in
traffic islands.
● If the operation of the Front Assist is im-
paired, f
or example, by dirt or because the ra-
dar sensor has lost its settings, the system
may issue unnecessary warnings and inter-
vene inopportunely in the braking.
● During driving, the Front Assist does not re-
act to peop
le or animals or vehicles crossing
your path or which approach you head-on in
the same lane.
● The driver must always be ready to take
over the c
ontrol of the vehicle. Note
● When the Front As

sist causes a braking,
the brake pedal is “harder”.
● Automatic interventions by the Front Assist
on the brake
s may be interrupted by pressing
the clutch, accelerator or moving the wheel.
● If the Front Assist does not work as descri-
bed in this c
hapter (e.g. in intervenes several
times unnecessarily), switch it off. Have the
system checked by a specialised workshop.

affic situation
››› Fig. 188 1 .
The r a
d

ar sensor's visibility may be impaired
by dirt, mud or snow, or by environmental in-
fluences such as rain or mist. In this case the
Front Assist monitoring system does not
work. The instrument panel displays the fol-
lowing message: Front Assist: No sensor vision! If necessary clean the ra-
dar sensor ››› .
When the r a
d

ar sensor begins to operate
properly again, the Front Assist will automati-
cally be available again. The message will
disappear from the instrument panel display.
Front Assist operation may be affected by a
strong radar reverse reflection. This may oc-
cur, for example, in a closed car park or due to the presence of metallic objects (e.g. rails
on the roa

d or sheets used in road works).
The area in front of and around the radar sen-
sor should not be covered with adhesives,
additional or similar headlights, as this may
negatively affect Front Assist operation.
If structural modifications are made to the ve-
hicle, for example, if the suspension is low-
ered or the front spoiler is modified, Front As-
sist operation may be affected. So structural
modifications should only be made by speci-
alised workshops. SEAT recommends visiting
a SEAT dealership for this purpose.
If work is done incorrectly on the front of the
vehicle, the radar sensor could be damaged
or lose its settings, and Front Assist opera-
tion may be affected. So repair work should
only be made by specialised workshops.
SEAT recommends visiting a SEAT dealership
for this purpose. CAUTION
If you have the sensation that the radar sen-
sor is d

amaged or has lost its settings, dis-
connect the Front Assist. This will avoid pos-
sible damage. If this occurs have it adjusted.
● The sensor may become damaged or lose
its settin
gs when knocked, for example, dur-
ing a parking manoeuvre. This may compro-
mise the system's efficacy or disconnect it. » 205
