 page 8 Central locking functions correctly when all
the doors and the r

ear lid are correctly shut.
If the driver door is open, the vehicle cannot
be locked with the key.
The battery of an unlocked vehicle parked for
a long period (e.g. in a private garage) may
run down and fail to start the motor. WARNING
The incorrect use of the central locking sys-
tem m a

y cause serious injuries.
● The central locking system will lock all
doors. A v
ehicle locked from the inside can
prevent any non-authorised individual from
opening the doors and accessing the vehicle.
Nevertheless, in case of emergency or acci-
dent, locked doors will complicate access to
the vehicle interior to help the passengers.
● Never leave children or disabled people
alone in the v
ehicle. The central locking but-
ton can be used to lock all the doors from
within. Therefore, passengers will be locked
inside the vehicle. Individuals locked in the
vehicle can be exposed to very high or very
low temperatures.
● Depending on the time of the year, temper-
ature
s inside a locked and closed vehicle can
be extremely high or extremely low resulting
in serious injuries and illness or even death,
particularly for young children.
● Never leave individuals locked in a closed
and locked
vehicle. In case of emergency,
they may not be able to exit the vehicle by
themselves or get help. 94

Opening and closing
Childproof lock Fig. 105
Childproof lock on the left hand side
door The childproof lock prevents the rear doors
fr
om bein
g opened fr
om the inside. This sys-
tem prevents minors from opening a door ac-
cidentally while the vehicle is running.
This function is independent of the vehicle
electronic opening and locking systems. It
only affects rear doors. It can only be activa-
ted and deactivated manually, as described
below:
Activating the childproof lock
– Unlock the vehicle and open the door in
which y

ou wish to activate the childproof
lock.
– With the door open, rotate the groove in
the door usin

g the ignition key, anti-clock-
wise for the left-hand side doors ››› Fig. 105 and clockwise for the right-hand side
doors.
De

activating the childproof lock
– Unlock the vehicle and open the door
whose chi

ldproof lock you want to deacti-
vate.
– With the door open, rotate the groove in
the door usin

g the ignition key, anti-clock-
wise for the right-hand side doors, and
clockwise for the left-hand side doors
››› Fig. 105.
Once the childproof lock is activated, the
door can only be opened from the outside.
The childproof lock can be activated or deac-
tivated by inserting the key in the groove
when the door is open, as described above.
Rear lid Introduction WARNING
Careless and unsuitable locking, opening and
clo s

ing of the rear lid can cause accidents
and serious injury.
● Open and close the rear lid only when no-
body is
in the way. ●
Do not c lo

se the rear lid by pushing it down
with your hand on the rear window. This
could break and cause injury.
● Ensure the rear lid is locked after closing,
otherwi
se, it may open unexpectedly while
driving. A closed rear lid should be flush with
the corresponding parts of the bodywork.
● Always keep the rear lid closed while driv-
ing to av
oid toxic gases entering the vehicle
interior.
● Do not open the rear lid when there is a
load in
stalled, for example a carrier system.
Likewise, the boot hatch cannot be opened
when a load is attached to it, for example bi-
cycles. An open rear lid could close itself if
there is an additional weight on it. If necessa-
ry, press down on the rear lid and remove the
load.
● Close and lock both the rear lid and all the
other doors when
you are not using the vehi-
cle. Ensure that nobody remains inside the
vehicle.
● Never allow children to play inside or
around the
vehicle without supervision, espe-
cially if the rear lid is open. Children could
enter the luggage compartment, close the
rear lid and become trapped. Depending on
the time of the year, temperatures inside a
locked and closed vehicle can be extremely
high or extremely low resulting in serious in-
juries and illness or even death, particularly
for young children.
● Never leave children or disabled people

9. WARNING
A faulty vehicle in traffic represents a risk of
acc ident
for the driver and for other road
users.
● Stop the vehicle safely as soon as possible.
Park the
vehicle a safe distance from sur-
rounding traffic to lock all the doors in case of
an emergency. Turn on the hazard warning
lights to warn other road users.
● Never leave children or disabled people
alone in the v
ehicle if the doors are to be
locked. In case of an emergency, passengers
will be trapped inside the vehicle. Individuals
locked in the vehicle can be exposed to very
high or very low temperatures. WARNING
The components of the exhaust system reach
ver y

high temperatures. This could cause a
fire and considerable damage.
● Always park your vehicle so that no part of
the exhau
st system can come in contact with
flammable materials (such as dried grass or
fuel). Note
● The v ehic

le battery will discharge and run
down if the hazard warning lights remain on
for too long (even with the ignition turned
off). 106

Transport and practical equipment
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

Operation
●
Never l e
ave the vehicle unattended if the
engine is running. The vehicle could move off
suddenly or something unexpected could
happen resulting in damage and serious in-
jury.
● Never use start boosters. Cold start sprays
coul
d explode or increase the engine speed
unexpectedly. WARNING
The components of the exhaust system reach
v er y

high temperatures. This could cause a
fire and considerable damage.
● Always park your vehicle so that no part of
the exhau
st system can come in contact with
flammable materials (such as wood, leaves,
spilled fuel, dried grass, etc).
● Never apply additional underseal or anti-
corro
sion coatings to the exhaust pipes, cata-
lytic converter or the heat shields on the ex-
haust system. WARNING
Unsuitable or careless use of the vehicle key
cou l

d result in serious injury.
● Always take all the keys with you whenever
you le
ave the vehicle. If not, the engine could
accidentally be started and electrical equip-
ment such as the windows could accidentally
be operated resulting in serious injury.
● Never leave children or disabled people
alone in the car
. Passengers could be trapped in the car in an emergency and not be able to
get
themselv

es to safety. For example, de-
pending on the time of the year, tempera-
tures inside a locked and closed vehicle can
be extremely high or extremely low resulting
in serious injuries and illness or even death,
particularly for young children.
● Never remove the key from the ignition if
the vehic
le is in motion. The steering may
lock and it will not be possible to turn the
steering wheel. CAUTION
● An attempt t

o start the engine while driving
or starting the engine immediately after turn-
ing it off can cause damage to the engine or
starter motor.
● When the engine is cold, avoid high revs
and heavy ac
celeration and do not make the
engine work hard.
● Do not push or tow start the engine. Un-
burnt f
uel could damage the catalytic con-
verter. For the sake of the environment
Do not warm the engine at idle speed; start
drivin g immedi

ately if the visibility is OK.
This helps the engine reach operating tem-
perature faster and reduces emissions. Note
● If the k ey

is left in the ignition lock with the
engine off for long periods, the vehicle bat-
tery will run flat.
● In automatic gearbox vehicles, the key can
only be r
emoved from the ignition lock if the
gear selector lever is in position N. In this
case, press and release the selector lever
locking button.
● Electrical devices with a high power con-
sumption are sw
itched off temporarily when
the engine starts.
● When the engine is started cold, there may
be stron
g vibrations for a few moments for
technical reasons. This is quite normal, and
no cause for concern.
● Natural gas engines always start up with
petrol, a
s a certain operating temperature is
required for running with gas. Once the re-
quired operating temperature is reached, the
engine will change to operate with natural
gas. Stopping the engine

ehicle impossible to control.
● Always park your vehicle so that no part of
the exhau
st system can come in contact with
flammable materials (such as wood, leaves,
dried grass, spilled fuel, etc.).
● Always apply the handbrake when you
leav
e your vehicle and when you park.
● Never leave children or disabled people
alone in the v
ehicle. They could release the
electronic parking brake, activate the selec-
tor lever or gear stick and start the vehicle
moving. This could result in a serious acci-
dent.
● Always take all the keys with you whenever
you le
ave the vehicle. The engine could acci-
dentally be started and electrical equipment
such as the windows could accidentally be
operated resulting in serious injury.
● Never leave children or disabled people
alone in the car
. They could be trapped in the
car in an emergency and will not be able to
get themselves to safety. For example, de-
pending on the time of the year, tempera-
tures inside a locked and closed vehicle can
be extremely high or extremely low resulting
in serious injuries and illness or even death,
particularly for young children. CAUTION
● Spec i

al care should be taken when parking
in areas with high kerbs or fixed barriers. Ob-
jects protruding from the ground may dam- age the bumper or other parts of the vehicle
during m
anoeu

vres. To avoid damage, stop
before the wheels touch the barrier or kerb.
● Special attention is required when driving
through entranc
es, over ramps, kerbs or oth-
er objects. The vehicle underbody, bumpers,
mudguards and running gear, and the engine
and exhaust system could be damaged as
you drive over these objects. Control and warning lamps
