WARNING
If the Smartphone is not secured or is incor-
rectly sec

ured in the vehicle, it could be
thrown though the passenger compartment
during a sudden driving or braking manoeu-
vre, just like in the event of an accident and
lead to injuries.
● The infotainment support system mus be
mounted sec
urely in the corresponding space
of the dash panel.
● The infotainment system must always be
well
secured in its support or kept safely in
the vehicle. CAUTION
If the lean and the angle of visibility are set
up incorr ectly

, the Smartphone can be dam-
aged.
● When performing the set-up, move the
Smartphone c
arefully and not beyond its lim-
its. CAUTION
At very high and very low temperatures, func-
tioning of the

Smartphone can be adversely
affected or the device itself can be damaged.
● Always take the Smartphone with you
when you l
eave the vehicle to protect it from
excessively high or low temperatures, as well
as from intense solar radiation. CAUTION
Humidity can damage the existing electrical
connect or

s in the dash panel for the Smart-
phone.
● Do not clean the Smartphone holder while
wet. On
ly use a dry cloth. Note
SEAT recommends always taking your Smart-
phone when y ou l

eave the vehicle so as to
avoid possible theft. Luggage compartment
Intr oduction Always transport heavy loads in the luggage
c
omp
ar

tment and place the seat backs in a
vertical position. Never overload the vehicle.
Both the carrying capacity as well as the dis-
tribution of the load in the vehicle have ef- fects on the driving behaviour and braking
ability

››› .
WARNING
When the vehicle is not in use or being
wat c

hed, always lock the doors and the rear
lid to reduce the risk of serious injury or
death.
● Do not leave children unwatched, especial-
ly when the boot i
s open. Children could
climb into the luggage compartment, close
the rear lid from inside and be unable to es-
cape themselves. This could lead to serious
injury or death.
● Never allow children to play in or around
the vehic
le.
● Never transport people in the luggage com-
partment
. 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
plac
e equipment and heavy objects in the
boot.
● Always secure objects to the fastening

Heavy loads that have not been stored or se-
cured correctly could cause loss of control
and result in serious injury.
● Vehicle handling changes when transport-
ing heavy
objects due to a change in the cen-
tre of gravity.
● Distribute the load as uniformly and as low
down on the v
ehicle as possible.
● Store heavy objects in the luggage com-
partment
as far from the rear axle as possi-
ble. CAUTION
Hard objects on the rear shelf could chafe

WARNING
If unsuitable or damaged belts or retaining
str ap
s are used, they may break in the event
of braking or an accident. Objects could then
be launched across the passenger compart-
ment and cause serious or fatal injuries.
● It is important to always use belts or retain-
ing str
aps that are suitable and in a good
condition.
● Belts and retaining straps should be se-
curely
fastened to the fastening rings.
● Objects in the luggage compartment that
are un
secured could move suddenly and mod-
ify the handling of the vehicle.
● Small light objects should also be fixed in
plac
e.
● A child seat should never be secured with
the fas
tening rings. Note
● The max imum t

ensile load that the fasten-
ing rings can support is 3.5 kN.
● Belts and securing systems for the appro-
priate lo
ad can be obtained from specialised
dealerships. SEAT recommends visiting a
SEAT dealership for this. Retaining hooks

Never use these hooks to secure objects. In
ca se of

sudden braking or an accident, they
could rupture. CAUTION
The hooks can support a maximum of 2.5 kg
eac h. Roof carrier
Intr oduction The vehicle roof has been designed to opti-
mise aer
ody

namics. For this reason, conven-
tional roof carrier systems cannot be secured
to the water drains.
Given that the water drains have been incor-
porated into the roof for aerodynamic rea-
sons, only the SEAT approved basic supports
and roof carrier systems can be used.
When the roof carrier system should be re-
moved:
● When they are not used.
● When the vehicle is being washed in a car
wa sh.
● When the

vehicle height exceeds the maxi-
mum height, for ex
ample, in some garages. WARNING
The risk of an accident is increased by trans-
portin g he

avy or bulky loads on the roof,
which affects the car's handling by shifting
the centre of gravity and increasing suscepti-
bility to cross winds.
● Always secure loads correctly with suitable
and undam
aged attachment rope or straps.
● Large, heavy, wide and flat loads negatively
affect the
vehicle aerodynamics, centre of
gravity and handling. » 127

expect the ABS to reduce the braking dis-
t anc
e u
nder any circumstances. This distance
will increase when driving on gravel, recent
snow or on icy or slippery ground.
Brake 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 system (ASR) or Traction
Control (TC)*
In the event of wheelspin, the traction control
system ASR or TC reduces the engine torque
to match the amount of grip available. The
ASR or TC makes some situations easier, for
example, when starting, accelerating or go-
ing uphill, even in unfavourable road condi-
tions. Electronic differential lock (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 one. To
prevent the disc brake of the braked wheel
from overheating, the EDL cuts out automati-
cally if subjected to excessive loads. The EDL
will switch on again automatically when the
brake has cooled down. WARNING
Driving at high speed on icy, slippery or 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
systems, 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
difficu
lt

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. WARNING
The effectiveness of the ESC* can be consid-
erab ly

reduced if other components and sys-
tems affecting driving dynamics are not main-
tained or are not functioning correctly. This
includes, among others, brakes, tyres and
other systems already mentioned.
● Remember that changing and fitting other
components
to the vehicle can affect opera-
tion of the ABS, BAS, ASR TC, EDL and ESC*.
● Changes to the vehicle suspension or using
unap
proved wheel/tyre combinations can af-
fect operation of the ABS, BAS, ASR, TC, EDL
and ESC* and their effectiveness.
● Likewise, the effectiveness of ESC* de-
pends on the u

Care and maintenance
The optimal reach of the equipment is only
ac hiev
ed w
ith an external aerial.
Check first with a specialised workshop that
understands the technical possibilities of in-
stallation if you wish to use a two-way radio
with a transmitting power of over 10 watts.
SEAT recommends taking your car in for tech-
nical service.
All legal requirements, together with the in-
structions for the use of two-way radios must
be observed. WARNING
If the two-way radio is not securely fastened
in pos ition, it

could be sent flying around the
vehicle in the event of sharp braking, sudden
manoeuvres or accident, causing injury.
● While driving, two-way radios must be se-
curely
fastened in position, outside the air-
bags deployment zones, or safely stowed
away. WARNING
When using a two-way radio without a con-
nection to an e xt

erior aerial, the maximum
permitted levels of electromagnetic radiation
may be exceeded. This is also the case if the
aerial has not been correctly installed.
● You should only use a two-way radio inside
the vehic
le if it has first been correctly con-
nected to an exterior aerial. Information stored by the control
u
nit
s Your vehicle is fitted at the factory with a ser-
ies
of

electronic control units responsible for
the engine and gearbox management. In ad-
dition, the control units supervise the per-
formance of the exhaust gas system and the
airbag systems.
Therefore, while the vehicle is being driven,
these electronic control units are continuous-
ly analysing the vehicle data. In the event of
faults or deviations from the theoretical val-
ues, only this data is stored. Normally, the
warning lamps on the instrument panel light
up in the event of faults.
This data can only be read and analysed us-
ing special equipment.
The storing of the data allows specialised
workshops to detect and repair faults. Stored
data may include:
● Data relating to the engine or the gearbox
● Speed
● Direction of travel
● Braking force
● Detection of seat belt
The v ehic

le control units never record conver-
sations held by passengers in the vehicle.
In vehicles equipped with an emergency call
function via the mobile phone or other appli- ances connected in the vehicle, it is possible
to send the v

ehicle position. If the control
unit records an accident with airbag activa-
tion, the system may automatically send a
signal. This will depend on the network oper-
ator. Normally, transmission is only possible
in areas with good coverage.
Event Data Recorder
The vehicle is not fitted with an event data re-
corder.
An event data recorder temporarily stores the
vehicle information. Therefore, in the event of
an accident, it is possible to obtain detailed
information about how the accident occur-
red. Vehicles with airbag systems can store
data relating to impact speed, seat belt sta-
tus, seat positions and airbag activation
times may be stored, etc. The volume of data
depends on the manufacturer.
Event data recorders can only be mounted
with authorisation from the vehicle owner
and, in some countries, they are governed by
local legislation.
Reprogramming control units
On the whole, all the data required for the
component management is stored in the con-
trol units. The programming of certain con-
venience functions, such as the turn signals,
individual door opening and instructions on
the display can be modified using special »

s are reprogrammed, the information
and Instruction Manual descriptions will not
coincide with the modified functions. There-
fore, SEAT recommends that any modifica-
tions be recorded in the section “Other work-
shop notes” in the Maintenance Programme.
The SEAT Official Service must have a record
of any modification to the programming.
Reading the vehicle fault memory
There is a diagnostics connector in the vehi-
cle interior for reading the vehicle fault mem-
ory. The fault memory documents errors and
deviations from the theoretical values of the
electronic control units.
The diagnostics connector is in the driver
side footwell area, next to the lever for open-
ing the bonnet, below a cover.
The fault memory should only be read and re-
set by a specialised workshop.
Using a mobile telephone in a vehicle
without c
onnection to an exterior aer-
ial Mobile telephones transmit and receive radio
w
av
e

s also called high-frequency energy,
both when in use and when on stand-by. Sci-
entific studies state that radio waves exceed-
ing certain values may be harmful to the hu- man body. International committees and au-
thorities h

ave established limits and direc-
tives in order to ensure electromagnetic radi-
ation from mobile phones remains within cer-
tain limits that do not endanger health. Nev-
ertheless, there is no conclusive scientific
evidence that wireless telephones are totally
safe.
That is why some experts recommend moder-
ate use of the mobile telephone, and the ap-
pliance of measures to reduce radiation on
the human body.
When a mobile phone not connected to an
exterior aerial is used inside the vehicle, the
electromagnetic radiation may be greater
than if the mobile phone were connected to a
built-in aerial or to another exterior aerial.
If the vehicle is fitted with a suitable hands-
free device that allows the employment of
numerous additional mobile telephone func-
tions with compatible Bluetooth technolo-
gy ®
, it will comply with the legislation in
many countries which only permits the use of
mobile phones inside vehicles using a
hands-free device.
Mobile telephones must be placed in a suita-
ble telephone support or stored safely in the
vehicle. If a support is used for the tele-
phone, it must be securely fastened to the
base plate. The mobile will be secure on the
instrument panel and always within reach of
the driver only by following these procedures. Mobile telephone connection with an exter-
nal aeri
al is carried out subject to the hands-
free device, via the telephone support or by
the Bluetooth ®
connections present in the
mobile telephone and the vehicle.
If the mobile phone is connected to an aerial
incorporated into the vehicle or an exterior
aerial connected to the vehicle, it will help re-
duce the electromagnetic radiation transmit-
ted and the risk to human health. It will also
improve the quality of the connection.
If the phone is used inside the vehicle with-
out the hands-free system, it will not be se-
curely fastened and will not be connected to
the exterior aerial of the vehicle telephone.
Nor will the telephone charge if it is not on
the support. In addition, some calls may
break off and the quality of the connection
will be affected.
Mobile telephones should only be used in-
side the vehicle if they are connected to a
hands-free system. SEAT recommends using
an external aerial should you wish to use a
mobile telephone inside the vehicle.
