CAUTION
At very high or very low temperatures the
smar tphone might
not operate properly, or
the actual device could get damaged.
● Take your smart phone with you when you
get out
of the vehicle to protect it from very
high or very low temperatures, and from in-
tense solar radiation. CAUTION
Humidity can damage the electrical contacts
for the sm ar

tphone on the instrument panel.
● Do not wet the smartphone’s housing when
cle
aning it. Use only a dry cloth. Note
SEAT recommends that you always take your
smar t

phone with you when you get out of
the vehicle to avoid possible thefts. 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
rings
with suitable rope or straps to prevent
them from being thrown around the interior and moving to the airbag deployment area in
the event
of

sudden movements or accidents.
● While driving, always keep object compart-
ments c
losed.
● Do not place hard, heavy or sharp objects
inside the
vehicle interior, in open storage
compartments, the rear shelf or on the dash
panel.
● Remove hard, heavy and sharp objects from
clothes
and pockets inside the vehicle and
store securely. WARNING
The transport of heavy object changes vehi-
cl e h

andling and increases braking distance.
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
again s

t the wires of the heating element in
the heated rear window and cause damage. » 123

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. ●
Av oid bru

sque manoeuvres and sudden
braking.
● Adjust your speed and driving style to visi-
bility
, road, traffic and weather conditions. CAUTION
● Alw a

ys remove the roof carrier system from
the roof before entering a car wash.
● The height of your vehicle is changed by
the inst
allation of the roof carrier and the
load secured on it. Compare the vehicle
height with the passage height, for example
in underground car parks or for garage doors.
● The roof antenna and the range of the rear
lid should not
be affected by the roof carrier
system or the load being transported.
● Take extra care not to let the hatch strike
the roof lo
ad when opening. For the sake of the environment
The vehicle uses more fuel when the roof car-
rier sys t

em is fitted. 127

and there is a risk of serious accident.
● The airbags and belt tensioners do not
work when the ignition i
s switched off.
● The brake servo does not work with the en-
gine off. T
o stop, the brake pedal must be
pressed with more force.
● As the power steering does not work if the
engine is
not running, you will need more
strength to steer than normally.
● If the key is removed from the ignition, the
steerin
g may lock and it will not be possible
to steer the vehicle. CAUTION
If the engine has been driven at high speed
for a pr o

longed period of time, it may over-
heat when turned off. To avoid engine dam- age, allow the engine to run for approximate-
ly 2 minut
e

s in neutral before switching it off. Note
After stopping the engine, the engine com-
p ar tment

fan may continue running for a few
minutes, even when the ignition has been
switched off or the key removed. The radiator
fan is automatically switched off. Electronic immobiliser
The gear lock prevents the engine from being
s
t
ar

ted with an unauthorised key and the ve-
hicle being moved.
The vehicle key has a built-in chip. It auto-
matically deactivates the electronic immobil-
iser when the key is inserted into the ignition
lock.
The electronic immobilizer will be activated
again automatically as soon as you remove
the key from the ignition lock.
For this reason, the vehicle can only be used
with a genuine SEAT key with the correct
code. Coded keys can be obtained from SEAT
dealerships ››› page 92.
If an unauthorised key is used, the signal 
appears on the instrument panel display. The
vehicle cannot be started in this case Note
The correct operation of the vehicle is only
guarant eed when origin

al SEAT keys are
used. Braking and parking
Introduction The assisted brake systems are the electron-
ic di

stribution of braking force (EBV), the an-
ti-lock brake system (ABS), the brake assist
system (BAS), the electronic differential lock
(EDL), traction control (TC)*, the traction con-
trol system (ASR) and the electronic stability
control (ESC*). WARNING
Driving with worn brake pads or a faulty
brak e sy

stem may lead to serious accident.
● If you believe the brake pads to be worn or
the brake sy
stem to be faulty, immediately
refer to a specialised workshop to check the
brake pads and replace the worn ones. WARNING
Careless parking can cause serious injury.
● Never remove the key from the ignition if

regulator operating.Take your foot off the accelera-
tor. Adjust your driving style to
the road conditions. Several warning and control lamps light up
for a f
ew sec

onds when the ignition is switch-
ed on, signalling that the function is being
verified. They will switch off after a few sec-
onds. WARNING
If the warning lamps are ignored, the vehicle
ma y

stall in traffic, or may cause accidents
and severe injuries.
● Never ignore the warning lamps.
● Stop the vehicle safely as soon as possible. WARNING
Driving with brakes in bad condition could re-
su lt

in a serious accident.
● If the brake warning lamp  does not
go
out, or if it lights up when driving, the brake
fluid level in the reservoir is too low or there
is a fault in the brake system. Obtain profes-
sional assistance immediately ››› page 194,
Checking the brake fluid level.
● If the brake warning lamp  lights up t
o-
gether with the ABS warning lamp , the
regulation function of the ABS could be mal-
functioning. As a result, the rear wheels can
lock relatively easily when braking. If the rear wheels lock this could result in loss of vehicle
contr
o

l! If possible, reduce your speed and
drive carefully to a specialised workshop
close by to check the brake system. During
the following journey, avoid sudden braking
and manoeuvres.
● If the ABS warning lamp  does not
go out
or if it lights while driving, the ABS is mal-
functioning. The vehicle can only be stopped
using normal braking without ABS. The pro-
tection provided by the ABS is not available.
Visit a specialised workshop as soon as pos-
sible. CAUTION
Failure to heed the warning lamps when they
appe ar m

ay result in faults in the vehicle. Brake assist systems
The assisted braking systems ESC*, ABS,
EB
V
, B

AS, ASR, TC and EDL only operate when
the ignition is switched on. They contribute
significantly to increasing active safety.
Electronic Stability Control (ESC)*
ESC* reduces the risk of skidding and increa-
ses the vehicle stability by braking individual
wheels under specific driving conditions.
ESC* detects critical handling situations,
such as understeer, oversteer and wheelspin
on the driven wheels. The system stabilises the vehicle by braking individual wheels or
by r

educing the engine torque.
The ESC* has limits. It is important to realise
that ESC* is also subject to the laws of phys-
ics. ESC* will not be able to deal with all sit-
uations with which drivers may be faced. For
example, if the road surface changes sudden-
ly then ESC* will not be useful in all cases. If
the vehicle suddenly enters a section cov-
ered by water, mud or snow then ESC* will
not provide assistance in the same way as on
dry ground. If the vehicle loses its grip on the
ground and moves on a film of water (“aqua-
planing”), the ESC* will not be able to help
the driver control the vehicle due to the loss
of adherence with the road surface prevent-
ing braking and steering. If the vehicle is
driven through series of bends at high
speed, the ESC* will not always be as effec-
tive: the vehicle reaction to aggressive driv-
ing is not the same as at reduced speeds.
Adjust your speed and driving style to suit
visibility, and weather, road and traffic condi-
tions. ESC* cannot push the limits of the laws
of physics; improve the transmission availa-
ble or maintain the vehicle on the road if a
lack of driver attention creates an inevitable
situation. Otherwise, ESC* assists in main-
taining vehicle control in extreme situations
and uses the movements of the steering
made by the driver to maintain the vehicle
moving in the desired direction. If the vehicle
is driven at such a speed that it will leave the »
