2018 Seat Arona ECU

Operation
●
If ther e i
s no valid key inside the vehicle or
the system fails to detect one, a warning will
display on the dash panel screen. This could
happen if any other radio frequency signal in-
terferes with the key signal (e.g. from a mo-
bile device accessory) or if the key is covered
by another object (e.g. an aluminium case).
● If the sensors are very dirty, e.g. have a lay-
er of sa
lt, the correct functioning of the sen-
sors on the door handles may be affected. In
this case, clean the vehicle.
● If the vehicle is equipped with an automatic
gearbo
x, it may only be locked in the gear
stick is in position P. Childproof lock
Fig. 144
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-
cidental

ly 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. 144
and clockwise for the right-hand side
doors.
Deactivating 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. 144.
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, a

s described above.
Anti-theft alarm* Des
cription of anti-theft alarm sys-
tem* The anti-theft alarm makes it more difficult to
bre
ak

into the vehicle or steal it. The system
will initiate acoustic and optical warning sig-
nals when your vehicle is tried to be forced.
The anti-theft alarm system is automatically
switched on when locking the vehicle. The
system is immediately activated and the turn
signal light located on the driver door will
flash along with the turn signals, indicating
that the alarm and the locking security sys-
tem (double lock) have been turned on.
If any of the doors or the bonnet are open,
they will not be included in the protection
zones of the vehicle when the alarm is con-
nected. If the door or the bonnet are subse-
quently closed, they will be automatically in-
cluded in the protection areas of the vehicle
and the turn signals will flash accordingly
when the doors close.
● The turn signal light will flash twice on
opening and de activ

ating the alarm.

Operation
mechanically, the time period from when
the door i s
opened u
ntil the key is inserted
into the contact should not exceed 15 sec-
onds, otherwise the alarm will be triggered.
– Press the button  on the remote c
ontrol
twice. The volumetric sensor and tilt sen-
sors will be deactivated. The alarm system
remains activated.
The vehicle interior monitoring and the anti-
tow system are automatically switched on
again next time the vehicle is locked.
The vehicle interior monitoring and anti-tow
sensor (tilt sensor) are automatically switch-
ed on when the anti-theft alarm is switched
on. In order to activate it, all the doors and
the rear lid must be closed.
If you wish to switch off the vehicle interior
monitoring and the anti-tow system, it must
be done each time that the vehicle is locked;
if not, they will be automatically switched on.
The vehicle interior monitoring and the anti-
tow system should be switched off if animals
are left inside the locked vehicle (otherwise,
their movements will trigger the alarm) or
when, for example, the vehicle is transported
or has to be towed with only one axle on the
ground. False alarms
Interior monitorin

g will only operate correctly
if the vehicle is completely closed. Please ob-
serve related legal requirements.
The following cases may cause a false alarm:
● Open windows (partially or fully),
● Movement of objects inside the vehicle,
such a
s loose papers, items hanging from
the rear vision mirror (air fresheners), etc. Note
● If the v

ehicle is relocked and the alarm is
activated without the volumetric sensor func-
tion, relocking will activate the alarm with all
its functions, except the volumetric sensor.
This function is reactivated when the alarm is
switched on again, unless it is deliberately
switched off.
● If the alarm has been triggered by the volu-
metric sensor
, this will be indicated by a
flashing of the warning lamp on the driver
door when the vehicle is opened. The flash is
different to the flash indicating the alarm is
activated.
● The vibration of a mobile phone left inside
the vehic
le may cause the vehicle interior
monitoring alarm to trigger, as both sensors
react to movements and shakes inside the ve-
hicle.
● If on activating the alarm, any door or the
rear lid i
s open, only the alarm will be activa-
ted. The vehicle interior monitoring and the anti-tow system will only be activated once
al
l

the doors are closed (including the rear
lid). Deactivating the vehicle interior moni-
torin
g and anti-t

ow system* When the vehicle is locked, the alarm will be
trigg
er

ed if movements are detected in the
interior (e.g. by animals) or if the vehicle's in-
clination is changed (e.g. during transport).
You can prevent the alarm from being trig-
gered accidentally by switching off the vehi-
cle interior monitoring and/or tow-away pro-
tection.
– To switch off the interior monitoring and
to w-

away protection, switch off the ignition
and, using the Infotainment system, select:  button >
S
ET
TINGS function button >
Openin g and c
lo

sing > Central locking >
Switch off alarm.
– When the vehicle is locked now, the vehicle
interior monitorin

g and the tow-away pro-
tection are switched off until the next time
the door is opened.
If the anti-theft security system (Safelock)*
››› page 133 is switched off, the vehicle interi-
or monitoring and the tow-away protection
are automatically switched off.

Operation
Note
● If the el ectric
al adjustment ever fails to op-
erate, the mirrors can be adjusted by hand by
lightly pressing the edge of the mirror glass.
● In vehicles with electric exterior mirrors,
the fol
lowing points should be observed: if,
due to an external force (e.g. being knocked
while manoeuvring), the adjustment of the
mirror housing is altered, the mirror will have
to be fully folded electrically. Do not readjust
the rear vision mirror housing by hand, as
this will interfere with the mirror adjuster
function.
● The fold-in function on the exterior mirrors
wil
l not activate at speeds over 40 km/h
(25 mph). Seats and head restraints

The safe driving chapter contains important
inform ation, tip

s, suggestions and warnings
that you should read and observe for your
own safety and the safety of your passengers
››› page 75. WARNING
● Never a dju

st the driver or front passenger
seat while the vehicle is in motion. While ad-
justing your seat, you will assume an incor-
rect sitting position. Risk of accidents. Adjust
the driver or front passenger seat only when
the vehicle is stationary.
● To reduce the risk of injury to the driver and
front p
assenger in case of a sudden braking
or an accident, never drive with the backrest
tilted towards the rear. The maximum protec-
tion of the seat belt can be achieved only
when the backrests are in an upright position
and the driver and front passenger have prop-
erly adjusted their seat belts. The further the backrests are tilted to the rear, the greater
the risk
of

injury due to improper positioning
of the belt web!
● Exercise caution when securing the seat
height into f
orwards/backwards position. In-
juries can be caused if the seat height is ad-
justed without due care and attention.
● To move the seat forwards and backwards,
pul
l upwards and not sideways on the lever,
as the force exerted on it in that direction
could damage it. Adjusting the front head restraints

– Secure loose loads with a luggage net* or
with non-ela

stic straps secured to the fas-
tening* rings. WARNING
● Loo se lug

gage and other objects in the lug-
gage compartment could cause serious inju-
ries.
● Always stow objects in the luggage com-
partment
and secure them with the fastening
rings*.
● During sudden manoeuvres or accidents,
loose ob
jects can be thrown forward, injuring
vehicle occupants or even third parties. This
increased risk of injury will be further in-
creased if a loose object is struck by an inflat-
ing airbag. If this happens, objects may
shoot outward like a missile. Risk of fatal in-
jury.
● Always keep all objects in the luggage com-
partment
and use appropriate grips to secure
them, particularly in the case of heavy ob-
jects. 158

Transport and practical equipment
●
Never e x
ceed the allowed axle weights or
allowed maximum weight. If said weights are
exceeded, the driving characteristics of the
vehicle may change, leading to accidents, in-
juries and damage to the vehicle.
● Please note that the centre of gravity may
shift when tr
ansporting heavy objects; this
may affect vehicle handling and lead to an ac-
cident. Therefore, it is essential to adjust
your speed and driving style accordingly, to
avoid accidents.
● Never leave your vehicle unattended, espe-
cia
lly when the rear lid is open. Children
could climb into the luggage compartment,
closing the door behind them; they will be
trapped and run the risk of death.
● Never allow children to play in or around
the vehic
le. Close and lock all the doors and
the rear lid when you leave the vehicle. Be-
fore you lock the vehicle, make sure that
there are no adults or children in the vehicle.
● Please observe the notes on the ›››
page 75. 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. Note
● The tyr e pr

essure must be adjusted accord-
ing to the load. When necessary, check the
tyre pressures on the adhesive label stuck to the back of the front left door frame

ompartment on page 158.
Example: An object weighing 4.5 kg is lying
unsecured in the vehicle. During a frontal col-
lision at a speed of 50 km/h (31 mph), this
object generates a force corresponding to 20
times its weight. That means that the effec-
tive weight of the object increases to approxi-
mately 90 kg. You can imagine the severity of
the injuries which might be sustained if this
“object” strikes an occupant as it flies
through the interior of the vehicle. This in- creased risk of injury will be further increased
if a loose o

bject is struck by an inflating air-
bag. WARNING
● If piec e

s of baggage or other objects are se-
cured to the fastening rings with inappropri-
ate or damaged retaining cords, injuries
could result in the event of braking manoeu-
vres or accidents.
● Never secure a child seat on the fastening
rings. 160
