Braking and stability systems Electronic Stability Control (ESC)* Fig. 140
Detailed view of the dash panel: ESC
switch. This Electronic Stability System reduces the
risk of skidding and improves the vehicle's
stability and ability to hold the road.
The Electronic Stability Control (ESC) contains
the electronic differential lock (EDL) and the
traction control system (ASR). The ESC works
together with the ABS. Both control lamps
will light up if the ESC or ABS systems are
faulty.
The ESC system is started automatically
when the engine is started. The ESC system is always active and cannot
be switched off. The ESC switch only switches
the ASR off.
The ASR can be deactivated when wheel spin
is desirable

F or e
xample:
● When driving with snow chains.
● When driving in deep snow or on loose sur-
faces.
● When the vehicle is stuck, to rock it back-
wards and forwards.
Press the button to switch the ASR back on
when you no longer need wheel spin.
Electronic Stability Control (ESC)*
The ESC reduces the risk of skidding by brak-
ing the wheels individually.
The system uses the steering wheel angle
and road speed to calculate the changes of
direction desired by the driver, and constant-
ly compares them with the actual behaviour
of the vehicle. When irregularities occur, for
example, if the vehicle begins to skid, the
ESC brakes the appropriate wheel automati-
cally.
The forces acting on the braked wheel bring
the vehicle back to a stable condition. If the
vehicle tends to oversteer (the rear end
slides out), the system will act on the front
wheel on the outside of the turn. WARNING
● Do not forget that the electronic stability
control ESC cannot defy the laws of physics.
This should be kept in mind, particularly on
slippery and wet roads and when towing a
trailer.
● Always adapt your driving style to suit the
condition of the roads and the traffic situa-
tion. The greater safety provided by the ESC
should not encourage you to run any risks. CAUTION
● To ensure that the ESC works correctly, all
four wheels must be fitted with the same
tyres. Any differences in the rolling radius of
the tyres can cause the system to reduce en-
gine power when this is not desired.
● Any modifications made to the vehicle (for
example, to the engine, brake system, run-
ning gear or to the combination of wheels
and tyres) may affect the operation of the
ABS, EDL, ESC and ASR. Electronic differential lock (EDL)*
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. In case of an EDL fault,

At s
peeds 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
the wheel which has lost traction and distrib-
uting more driving force to the other driven
wheel via the differential.
To prevent the disc brake of the braking
wheel from overheating, the EDL cuts out au-
tomatically if subjected to excessive loads.
The vehicle will continue to function normally
without EDL. For this reason, the driver is not
informed that the EDL has been switched off.
The EDL will switch on again automatically
when the brake has cooled down. WARNING
● When accelerating on a slippery surface,
for example on ice and snow, press the accel-
erator carefully. Despite EDL, the driven
wheels may start to spin. This could impair
the vehicle's stability.
● Always adapt your driving style to suit road
conditions and the traffic situation. Do not let
the extra safety afforded by EDL tempt you in-
to taking any risks when driving, this can
cause accidents. CAUTION
Modifications to the vehicle (e.g. to the en-
gine, the brake system, running gear or any
components affecting the wheels and tyres)
could affect the efficiency of the EDL
››› page 155. Hydraulic Brake Assist (HBA)*
The function (Hydraulic Brake Assist HBA) is
only included in vehicles with ESC.
In an emergency, most drivers brake in time,
but not with maximum force. This results in
unnecessarily long braking distances.
This is when the brake assist system comes
into action. When pressing the brake pedal
rapidly, the assistant interprets it as an emer-
gency. It very quickly builds up the full brake
pressure so that the ABS can be activated
more quickly and efficiently, thus reducing
braking distance.
Do not reduce the pressure on the brake ped-
al, since the brake assist system switches off
automatically as soon as you release the
brake.
Automatic hazard warning lights activation
The brake lights flash automatically to indi-
cate that the vehicle is braking suddenly or in
an emergency situation. If the emergency
braking continues until the vehicle comes toa standstill, the hazard warning lights will
then come on and the brake lights will re-
main on permanently from that moment. The
warning lights will automatically switch off
when the vehicle begins to move again or
when the "warning" light button is pressed.
WARNING
● The risk of accident is higher if you drive
too fast, if you do not keep your distance from
the vehicle in front, and when the road sur-
face is slippery or wet. The increased acci-
dent risk cannot be reduced by the brake as-
sist system.
● The brake assist system cannot defy the
laws of physics. Slippery and wet roads are
dangerous even with the brake assist system!
Therefore, it is essential that you adjust your
speed to suit the road and traffic conditions.
Do not let the extra safety features tempt you
into taking any risks when driving. Anti-lock brake system (ABS)
The anti-lock brake (ABS) system prevents
the wheels from locking during braking and
is an important part of the vehicle's active
safety system.
How the ABS works
If one of the wheels turns too slowly in rela-
tion to the vehicle's speed, and is close to
locking, the system will reduce the braking
140

Driver assistance systems
pressure to this wheel. The driver is made
aware of this control process by a pulsating
of the brake pedal and audible noise. This is
a deliberate warning to the driver that one or
more of the wheels 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.
Br ak
ing distance could even be further if you
brake on gravel or on fresh snow on a slip-
pery surface. WARNING
● The anti-lock brake 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 tyres fitted ››› page 176.
● If the ru

nning gear or brake system is modi-
fied, the effectiveness of the ABS could be se-
verely limited. Traction control system (ASR)*
The traction control system prevents the driv-
en wheels from spinning when the vehicle is
accelerating. This system always includes
ABS.
Description and operation of the traction
control system during acceleration (ASR
On front-wheel drive vehicles, the ASR sys-
tem intervenes, reducing engine power and
preventing the driven wheels from slipping
during acceleration. The system works in the
entire speed range in conjunction with ABS.
If a failure occurs in the ABS, the ASR will al-
so stop working.
TCS helps the car to start moving, accelerate
and climb a gradient in slippery conditions
where this may otherwise be difficult or even
impossible.
The ASR automatically switches on when the
engine is started. If necessary, it may be
turned on or off by briefly pressing the ESC
button on the centre console.
When the ASR is off, the warning lamp lights
up . The ASR should normally be left on.
Only in exceptional circumstances, when
wheel spin is required, can they be turned off
using the ESC button, for example:
●
With compact temporary spare wheel.
● When using the snow chains. ●
When driving in deep snow or on soft ter-
rain.
● When the vehicle is bogged-down, to free it
“by rocking it.”
The ASR should be switched on again as
soon as possible. WARNING
● Remember that not even the ASR can defy
the laws of physics. This should be kept in
mind, particularly on slippery and wet roads
and when towing a trailer.
● Always adapt your driving style to suit the
condition of the roads and the traffic situa-
tion. The greater safety provided by the ASR
should not encourage you to run any risks. CAUTION
● To ensure that the ASR works correctly,
identical tyres should be fitted on all four
wheels. Any differences in the rolling radius
of the tyres can cause the system to reduce
engine power when this is not desired.
● Any modifications made to the vehicle (for
example, to the engine, brake system, run-
ning gear or to the combination of wheels
and tyres) may affect the operation of the
ABS and ASR. 141

Operation
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.
Brake servo The brake servo increases the pressure you
apply to the brake pedal. It works
only when
the engine is running . If the brake servo is not functioning, e.g. due
to a malfunction, or if the vehicle is being
towed, you will have to press the brake pedal
considerably harder to make up for the lack
of servo assistance.
WARNING
The braking distance can also be affected by
external factors.
● Never let the vehicle coast with the engine
switched off. Failure to follow this instruction
could result in an accident. The braking dis-
tance is increased considerably when the
brake servo is not active.
● If the brake servo is not working, for exam-
ple when the vehicle is being towed, you will
have to press the brake pedal considerably
harder than normal. Start-Stop System*
Description and operation The Start-Stop function stops the engine
when the vehicle is stopped and starts it au-
tomatically when required.
– When the vehicle is stopped, put it in neu-
tral and release the clutch pedal. The en-
gine will stop.
– When the clutch pedal is pressed, the en-
gine starts again. –

Start-Stop function interruption
In the following situations, the Start-Stop
function will be interrupted and the engine
will automatically start:
● The vehicle starts moving.
● The brake pedal is pressed several times in
a row.
● The battery has been discharged excessive-
ly.
● The Start-Stop System is manually deacti-
vated.
● The windscreen de-mist function is turned
on.
● The temperature of the interior exceeds the
comfort limits ( A/C button).
● If the airflow is increased by more than 3
presses.
● Temperature setting HI or LO is selected.
● The engine coolant temperature is insuffi-
cient.
● The alternator is faulty, for example the V-
belt has ruptured.
● If any of the conditions described in the
previous section are not fulfilled. WARNING
Never allow the vehicle to move with the en-
gine off for any reason. You could lose control
of your vehicle. This could cause an accident
and serious injury. ●
The brake servo does not work with the en-
gine off. You need more force to stop the vehi-
cle.
● Power steering does not work when the en-
gine is not running. That is why it is much
more difficult to turn the steering wheel.
● Turn off the Start-Stop system when driving
through water (fording streams, etc.). Note
● For vehicles with the Start-Stop function
and a manual gearbox, when the engine is
started, the clutch must be pressed.
● When the conditions for the Start-Stop
function are not fulfilled, the instrument pan-
el displays the Start-Stop indicator dimmed.
● If the steering wheel is turned more than
270°, it will not be possible to start the vehi-
cle again. To start the vehicle, straighten the
steering wheel so that it is turned less than
270°. Activating and deactivating the Start-

Operating and safety warnings WARNING
● The Rear Assist does not make it possible
to precisely calculate the distance from ob-
stacles (people, vehicles, etc.) and nor can it
overcome the system's own limits, hence us-
ing it may cause serious accidents and inju-
ries if used negligently or without due care.
The driver should be aware of his/her sur-
roundings at all times to ensure safe driving.
● The camera lens expands and distorts the
field of vision and displays the objects on the
screen in a different, vague manner. The per-
ception of distances is also distorted by this
effect. ●
Some objects may, due to the resolution of
the display screen - not be displayed in a sat-
isfactory manner or may not be displayed at
all. Take special care with thin posts, fences,
railings or trees that might not be displayed
on screen and could damage the vehicle.
● The rear assist has blind spots where it is
not possible to represent people or objects
(small children, animals and certain objects
cannot be detected in its field of vision). Mon-
itor the vehicle's surrounding area at all
times.
● Keep the camera lens clean, free of ice and
snow, and do not cover it.
● The system is not a replacement for driver
awareness. Supervise the parking operation
at all times, as well as the vehicle's surround-
ing area. Adapt your speed and driving style
at all times to suit visibility, weather, road
and traffic conditions.
● Do not be distracted from the traffic by
looking at the screen.
● The images on the rear assist screen are
only two-dimensional. Due to a lack of spatial
depth, protruding parts or holes in the road,
for example, are more difficult to detect or
may not be seen at all.
● Vehicle load modifies the representation of
the orientation lines displayed. The width
represented by the lines diminishes with ve-
hicle load. Pay special attention to the vehi-
cle's surroundings when the inside of the ve-
hicle of the luggage compartment is carrying
a heavy load. 144

Driver assistance systems
●
In the following situations, the objects or
other vehicles shown in the navigation sys-
tem display appear to be further away or
closer than they really are: Pay special atten-
tion:
–On moving from a horizontal plane to a
slope.
– On moving from a slope to a horizontal
plane.
– If the vehicle is heavily loaded at the
rear.
– When the vehicle approaches objects
that are not on the ground surface or are
jutting out from it. These objects may al-
so be outside the camera's angle of vi-
sion when reversing. Note
It is important to take great care and pay spe-
cial attention if you are not yet familiar with
the system. Instructions for use

Necessary conditions for parking and
manoeuvring with the
The system should not be used in the follow-
ing cases:
● If the image displayed is not very reliable or
is distorted, for example low visibility or dirty
lens. ●
If the area behind the vehicle is not dis-
played very clearly or is incomplete.
● If the vehicle is heavily loaded at the rear.
● If the position and installation angle of the
camera have been changed, e.g. after a rear-
end collision. Have the system checked by a
specialised workshop.
Familiarising yourself with the system
To familiarise yourself with the system, the
orientation lines and their function, SEAT rec-
ommends practising parking and manoeu-
vring with the rear assist in a place without
too much traffic or in a car park when there
are good weather and visibility conditions.
Cleaning the camera lens
Keep the camera lens clean and clear of snow
and ice:
● Moisten the lens using a normal alcohol-
based glass cleaning product and clean the
lens with a dry cloth.
● Remove snow using a small brush.
● Use de-icing spray to remove any ice. CAUTION
● Never use abrasive cleaning products to
clean the camera lens.
● Do not use hot or warm water to remove ice
or snow from the camera lens. Doing so could
damage the camera. 145

4 Parking aid*
General information Various aid systems are in place to help in
parking and manoeuvring depending on the
vehicle’s equipment:
The rear parking aid
is an audible aid that
w

arns against obstacles behind the vehicle
››› page 147.
The front parking aid i
s an audible aid that
warns against obstacles both behind and in
front of the vehicle ›››
page 148.
Apart from the acoustic signals, when the ve-
hicle is equipped with a portable navigator
(PND), this visually displays information re-
garding front and/or rear areas. WARNING
● The sensors have blind spots in which ob-
stacles may not be detected.
● Always look out for small children and ani-
mals because the system will not always de-
tect them. Pay attention when reversing to
avoid accidents.
● The parking aid is not a replacement for
driver awareness. The driver must take full re-
sponsibility for parking and other manoeu-
vres. 146

Driver assistance systems
Rear parking aid The parking aid system will use an audible
warning to indicate of the approach of any
object towards the rear of the vehicle.
Description
The acoustic parking aid system will measure
the distance between the rear of the vehicle
and any possible obstacle using four ultra-
sonic sensors located on the rear bumper.
The measuring range of the sensors starts
approximately and depending on the nature
of the obstacle
at a distance of:
● side of the rear bumper: 0.6 m
● middle of the rear bumper: 1.6 m
Activation
The system is activated by engagement of
the reverse gear. A brief audible warning con-
firms the activation and correct function of
the system.
Reverse gear
The distance warning will begin as soon as
an obstacle is detected by the system. The
frequency of the bleeps emitted by the sys-
tem will increase rapidly as the vehicle ap-
proaches the obstacle. After a distance lower
than approximately 30 cm, a continuous sig-
nal sounds (stop signal). The driver should
not reverse any further. Models with a factory-fitted towing bracket:
when the vehicle is less than 0.35 m away
the warning tone will sound continuously.
The driver should then not reverse any fur-
ther.
The warning tone volume decreases by 30%
3 seconds after it the system is triggered
if
the detected obstacle stays at a constant dis-
tance from the vehicle .
Provided that it is not in continuous mode,
the tone on the parking aid system stops
when it detects a wall parallel to the vehicle.
Trailer towing
For vehicles factory-fitted with a towing bar,
the parking aid system will not be activated
by the engagement of the reverse gear when
pulling a trailer, as the trailer's electric con-
nector will be plugged into the vehicle.
Possible faults
If a continuous beep sounds for some sec-
onds when the reverse gear is engaged, this
indicates that there is a fault in the parking
aid system. If the fault continues until the ig-
nition is turned off, the audible warning of
the fault will not be emitted every time the
system is reactivated (by engaging the re-
verse gear). Thus, the system ready indica-
tion will not sound either. Have the fault re-
paired by technical services as soon as possi-
ble. If there is no ready signal or no acoustic
warning signal, then the parking aid loud-
speaker is faulty and may not warn of obsta-
cles. To ensure that the system works proper-
ly, the sensors must be kept clean and free of
ice and snow.
CAUTION
● Please note that low obstacles detected by
the system may no longer be registered by
the sensors as the car moves closer, so the
system will not give any further warning. Cer-
tain kinds of obstacles, such as wire fences,
chains, thin posts or trailer draw bars, high
kerbs or painted railings, etc., may not al-
ways be detected by the system, so there is a
risk of damaging the vehicle in such cases.
● In some case, obstacles with edges and
bumps may not be detected immediately by
the system due to their geometry. Take spe-
cial care with this type of obstacle (corners,
rectangular objects, etc.), as they can cause
damage to the vehicle.
● Be especially careful when manoeuvring in-
to a corner between two perpendicular walls.
Pay special attention to the side distance
from the wall using the mirrors.
● The parking aid system does not replace
use of the mirrors for manoeuvres.
● External ultra-sonic sources (pneumatic
drills, construction machinery, other vehicles
with PDC) may interfere with the operation of
the system. » 147Technical specifications

Operation
●
Periodic cleaning of the sensors, take care
not to damage or scratch them. When clean-
ing with high pressure washers or steam
cleaners, the sensors should be sprayed for
only a very short period and from a distance
of more than 10 cm.
● If the licence plate (especially the front
one) is bent in such a way that it noticeably
juts out from the bumper, false alarms may
sound for the area in front of the vehicle. Rear parking aid with navigator view

Parking aid view on the navigation
screen. When the parking aid system has been acti-
vated, the navigation view screen is also si-
multaneously activated (if one of the doors or
the rear lid is open, it must be closed before
the on-screen information can be viewed).
The distance of separation from the obstacle
can be estimated
››› Fig. 145 with the help of the segments around the vehicle. The white
segments represent obstacles located be-
tween 30 cm and 160 cm from the vehicle’s
rear. As the vehicle approaches an obstacle,
the segments are displayed closer to the ve-
hicle. The red segments represent obstacles
located at less than 30 cm from the front
bumper. At this point the driver should not
reverse any further.
Front parking aid Description
The acoustic parking aid system measures
the distance between the vehicle and any
possible obstacle using 8 ultrasonic sensors
(4 of which are located on the rear bumper
and 4 of which are located on the front
bumper).
The measuring range of the sensors starts
approximately and depending on the nature
of the obstacle
at a distance of:
● side of the front bumper: 0.6 m
● middle of the front bumper: 1.2 m
● side of the rear bumper: 0.6 m
● middle of the rear bumper: 1.6 m
Activation
The system may be activated in the following
ways: ●
Engage the reverse gear (a brief, sharp
acoustic signal confirms activation and the
correct operation of the system) or
● Push the central console button  (a brief
confirmation signal will sound and the but-
ton’s LED will light up).
Disconnection
The system may be deactivated in the follow-
ing ways:
● Drive forwards at more than approx.
10 km/h (6 mph) or
● Press the  button, or
● Switch the ignition off.
Manoeuvres
The distance warning will begin as soon as
an obstacle is detected in the system's field
of detection (front and rear). The frequency of
the bleeps emitted by the system will in-
crease rapidly as the vehicle approaches the
obstacle. Two speakers, one in the front and
one in the rear, indicate the location of the
obstacle ( front and rear, respectively).
After a distance lower than approximately 30
cm, a continuous signal sounds (stop signal).
At this point the driver should halt the vehi-
cle.
Models with a factory-fitted towing bracket:
when the vehicle is less than 0.35 m away
the warning tone will sound continuously.
