Rain sensor modified behaviour
Possible causes of faults and mistaken read-
ings on the sensitive surface ››› Fig. 145 of
the rain sensor include:
● Damaged blades: a film of water on the
damag
ed blades may lengthen the activation
time, reduce the washing intervals or result
in a fast and continuous wipe.
● Insects: insects on the sensor may trigger
the winds
creen wiper.
● Salt on roads: in winter, salt spread in the
roa
ds may cause an extra long wipe when the
windscreen is almost dry.
● Dirt: dry dust, wax, coating on glass (Lotus
effect) or trac
es of detergent (car wash) may
0 1
A reduce the effectiveness of the rain sensor or
m
ak
e it

react more slowly, later or not at all.
● Cracked windscreen: the impact of a stone
wil
l trigger a single wipe cycle with the rain
sensor on. Next the rain sensor detects the
reduction in the sensitive surface area and
adapts accordingly. The behaviour of the sen-
sor will vary with the size of the damage
caused by the stone. WARNING
The rain sensor may not detect enough rain
to sw it

ch on the wipers.
● If necessary, switch on the wipers manually
when water on the w
indscreen obstructs visi-
bility. Note
● Cle

an the sensitive surface of the rain sen-
sor regularly and check the blades for dam-
age ››› Fig. 145 (arrow).
● To remove wax and coatings, we recom-
mend a window c
leaner containing alcohol. Rear vision mirror
Intr oduction WARNING
The automatic anti-dazzle rear vision mirror
cont ain

s an electrolytic fluid which may leak
if the mirror is broken. This could cause irrita-
tion to the skin, eyes and respiratory organs.
● The electrolytic fluid may cause irritation to
the skin, eye
s and respiratory organs, partic-
ularly in individuals suffering from asthma or
other illnesses. Make sure that adequate
quantities of fresh air enter and leave the ve-
hicle if it is not possible to open all the doors
and windows.
● If the electrolytic fluid comes into contact
with eye
s or skin, wash the area for at least
15 minutes with plenty of water, and seek
medical advice.
● If the electrolytic fluid comes into contact
with shoes
or clothing, wash the area for at
least 15 minutes with plenty of water. Wash
shoes and clothing before wearing them
again.
● If the electrolytic fluid is swallowed, wash
your mouth with p
lenty of water for at least
15 minutes. Do not try to provoke vomiting
unless recommended by a Doctor. Seek medi-
cal advice immediately. » 137

Operation
WARNING
The centre armrest may limit the freedom of
mov ement
of the driver's arm and cause a se-
rious accident.
● Keep the centre armrest compartments
closed whi
le the vehicle is in motion.
● The centre armrest is not designed for chil-
dren to s
it on! Sitting in this incorrect posi-
tion can cause severe injuries. Transport and practical

Introduction Always transport heavy loads in the luggage
comp
ar

tment and place the seat backs in a
vertical position. Always use the anchors pro-
vided with suitable rope to secure heavy ob-
jects. Never overload the vehicle. Both the
carrying capacity as well as the distribution
of the load in the vehicle affect driving be-
haviour and braking ability ››› .
WARNING
Unsecured or incorrectly secured objects can
cau se seriou

s injury in case of a sudden ma-
noeuvring or breaking or in case of an acci-
dent. This is especially true when objects are
struck by a detonating airbag and fired
through the vehicle interior. To reduce the
risks, please note the following:
● Secure all objects in the vehicle. Always
keep equipment and he
avy objects in the lug-
gage compartment.
● Always secure objects with suitable rope or
sling
s so that they cannot enter the areas
around the front or side airbags in case of
sudden braking or an accident. ●
Alw a

ys ensure that objects inside the vehi-
cle cannot move into the area of the airbags
while driving.
● While driving, always keep object compart-
ments c
losed.
● Remove all objects from the front passen-
ger seat
when it is folded down. When the
seat backrest is folded down, it presses on
small and light objects and these are detec-
ted by the weight sensor on the seat; this
sends false information to the airbag control
unit.
● While the backrest of the front passenger
seat i
s folded, the front airbag must remain
disabled and the PASSENGER AIRBAG OFF  light on.
● Objects secured in the vehicle should never
be plac
ed in such a way as to make passen-
gers sit in an incorrect position.
● If secured objects occupy a seat, this seat
should not
be occupied or used by anyone. WARNING

Operation
WARNING
Wet, frozen or salt-covered brakes take lon-
ger t o en
gage and this increases braking dis-
tances.
● Test the brakes carefully.
● Dry the brakes, free them of ice and salt by
brakin
g gently several times, when weather,
road and traffic conditions permit. WARNING
Driving without the brake servo may signifi-
cantly inc

rease the braking distance and re-
sult in a severe accident.
● Never allow the vehicle to move forwards
when the engine is
switched off.
● If the brake servo does not operate or the
vehicl
e must be towed, then the brake pedal
will have to be pressed with more force given
that the braking distance will be increased
when the brake servo does not operate. CAUTION
● Never m ak

e the brakes “slip” by pressing
the pedal gently, if it is not really necessary
to brake. Continuously pressing on the brake
pedal will heat the brakes. This could signifi-
cantly reduce braking power, increase brak-
ing distance or even result in the total failure
of the brake system.
● Reduce speed or change down a gear when
faced w
ith steep and long slopes. This allows
you to use the engine braking effect and to reduce the strain on the brake system. Other-
wi
se, the br

akes may overheat and fail. Only
use the brakes to reduce speed or to stop. Note
When checking the front brake pads, take the
time t o al

so check the rear brake pads. The
thickness of the brake pads should be
checked visually and regularly, by looking
through the openings in the wheel rims or
from underneath the vehicle. If necessary, re-
move the wheels to check them thoroughly.
SEAT recommends taking your car in for tech-
nical service. Gearbox
Intr oduction When reverse gear is engaged and the igni-
tion i
s
sw

itched on the following takes place:
● Reverse lights light up.
● When reversing, the air conditioner auto-
matical
ly changes to air recirculation mode.
● The rear window heater switches on when
the winds
creen wiper is activated.
● Also, the parking sensor system, the opti-
cal p
arking sensor and the camera for the re-
verse assist system are connected. WARNING
Rapid acceleration can cause loss of traction
and skid din

g, especially on slippery ground.
This could cause loss of control of the vehicle
resulting in an accident and considerable
damage.
● Only use the kick-down function or rapid
accel
eration if visibility, weather, road and
traffic conditions so permit. WARNING
Do not allow the brakes to “rub” for a pro-
long ed period of

time, or brake frequently or
for long periods of time. Continuous braking
heats up the brakes. This could significantly
reduce braking power, increase braking dis-
tance or even result in the total failure of the
brake system. Control and warning lamps

Operation
front wheels are turned, the normal ABS is
activ at
ed.
Br
ake assist system (BAS)
The brake assist system may reduce the re-
quired braking distance. The brake assist
system boosts the braking force if you press
the brake pedal quickly in an emergency. As
a result, the braking pressure increases rap-
idly, the braking force is multiplied and the
braking distance is reduced. This enables the
ABS to be activated more quickly and effec-
tively.
¡Do not lift your foot off the brake pedal!
When the brake pedal is released or when
the brake force is reduced, braking assist au-
tomatically turns off the brake servo.
Traction control when accelerating (ASR)
In the event of wheelspin, the traction control
system reduces the engine torque to match
the amount of grip available. The ASR makes
some situations easier, for example, when
starting, accelerating or going uphill, even in
unfavourable road conditions.
The ASR can be switched on or off manually
››› page 205.
Electronic differential lock system (EDS)
EDL is available when driving in straight lines
under normal conditions. When the EDL de-
tects wheelspin, it brakes the spinning wheel and directs the power to the other drive
wheels. T
o prevent the disc brake of the
braked wheel from overheating, the EDL cuts
out automatically if subjected to excessive
loads. The EDL will switch on again automati-
cally when the brake has cooled down.
Electronic drive torque management (XDS)
When taking a curve, the driveshaft differen-
tial mechanism 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.
Via the ESC, the XDS will brake the inside
wheel and counter the excess driving torque
of that wheel. This means that the driver's
desired trajectory is much more precise.
The XDS system works in combination with
the ESC and is always active, even when ASR
traction control is disconnected. WARNING
Driving at high speed on icy, slippery wet
grou nd c

an result in loss of vehicle control
and serious injury to the driver and passen-
gers.
● Adjust your speed and driving style to visi-
bility
, road, traffic and weather conditions.
Even though the brake assist systems, ABS,
BAS, EDL, ASR and ESC, provide more securi-
ty, do not take unnecessary risks while driv-
ing.
● Brake assist systems can not overcome the
law
s of physics. Even with ESC and other sys-
tems, slippery and wet roads will always be
dangerous.
● Driving to quickly on wet ground can result
in the wheels lo
sing contact with the ground
in an effect known as “aquaplaning”. Without
adherence, it is impossible to brake, steer or
control the vehicle.
● Brake assist systems cannot avoid acci-
dents if
, for example, the driver does not re-
spect safety distances or drives to quickly in
difficult conditions.
● Even though brake assist systems are ex-
tremely eff
ective and help control the vehicle
in difficult situations, remember that the ve-
hicle stability depends on tyre grip.
● When accelerating on a slippery surface,
for ex
ample on ice or snow, press the acceler-
ator carefully. The wheels can still slip even
with brake assist systems resulting in loss of
vehicle control. 204

t
em*
Intr oduction The parking distance warning system assists
the driv
er when p
ark

ing. When the vehicle
approaches an obstacle, forwards or back-
wards, an intermittent audible warning will
be heard, higher or lower depending on the
distance. The shorter the distance, the short-
er the intervals between tones. If the vehicle
is too close to the obstacle, the audible warn-
ing becomes constant.
If you continue to approach an obstacle when
the sound is continuous, this means the sys-
tem can no longer measure the distance.
The sensor system on the bumpers transmit
and receive ultrasound. Using the ultrasound
signal (transmission, reflection from the ob-
stacle and reception), this system
208

Driver assistance systems
continuously calculates the distance be-
tw een the b
umper and the o
bstacle.WARNING
The parking distance warning system and the
optica l

parking system cannot replace driver
awareness.
● The sensors have blind spots in which ob-
stac
les and people are not registered.
● Always observe the area around the vehi-
cle, a
s the sensors do not always detect
small children, animals or objects.
● The surface of certain objects and some
clothing do not
reflect the ultrasound signals
from the parking distance system. The sys-
tem cannot detect or incorrectly detects
these objects and people wearing these
types of clothes.
● External sound sources can affect the park-
ing dis
tance aid signals. In this case, under
certain circumstances, people and objects
will not be detected. CAUTION
● The sensor s

may not always be able to de-
tect objects such as trailer draw bars, thin
rails, fences, posts, trees and open boots,
etc. This could result in damage to your car.
● Although the parking distance warning sys-
tem detect
s and warns of the presence of an
obstacle, the obstacle could disappear from
the angle of measurement of the sensors if it
is too high or low and the system would no longer show it. Therefore, it will not warn you
of the
se o

bjects. Ignoring the warnings of the
parking sensor system could cause consider-
able damage to the vehicle.
● The bumper sensors may become damaged
or misa
ligned, for example, when parking.
● To ensure that the system works properly,
the bumper sensor
s must be kept clean, free
of ice and snow and uncovered.
● When cleaning the sensors with high-pres-
sure or s
team cleaning equipment, spray the
sensors briefly at a distance of no less than
10 cm (4 inches). Note
Acoustic sources may lead to erroneous warn-
ing s

on the parking sensor system, e.g.
rough tarmac, cobbles or the noise of other
vehicles. Parking distance warning system*

table on page 2
The Park Assist system helps the driver to
find a suitable place to park, to insert the ve-
hicle into parallel and perpendicular parking
places and to leave parallel parking places.
The Park Assist system is limited to the sys-
tem abilities and requires that the driver is
especially attentive ››› .
The p ark
in

g sensor system is a component of
the Park Assist system that helps to park the
vehicle.
For vehicles with the optical parking system
(OPS), the radio navigation systems screen
displays the detected zones in front of and
behind the vehicle, indicating - within the
limits of the system - the position of obsta-
cles in relation to the vehicle.
The park assist system cannot be switched
on if the factory-fitted towing bracket is elec-
trically connected to a trailer. »
