 page 60.
Tow-starting means starting the engine of
the vehicle while another pulls it.
Towing means one vehicle pulling another
that is not roadworthy.
If the vehicle comes with the Keyless Access
system, towing is only allowed with the igni-
tion on!
The vehicle battery drains if the vehicle is
towed with the engine switched off and the
ignition connected. Depending on the battery
charge status, the drop in voltage may be so
large, even after just a few minutes, that no
electrical device in the vehicle may work e.g.
the hazard warning lights. In vehicles with the Keyless Access system, the steering
wheel cou

ld lock up. WARNING
If the vehicle has no electrical power, the
brak e light

s, turn signals and all other lights
will no longer function. Do not have the vehi-
cle towed away. Failure to follow this instruc-
tion could result in an accident. WARNING
The risk of accidents is high when tow-start-
ing, f or e

xample, the towed vehicle can easily
be driven into the towing vehicle. CAUTION
If there is no oil in the gearbox or no lubricant
in the autom atic

transmission the car may
only be towed with the driven wheels lifted
clear of the road, or transported on a special
car transporter or trailer. CAUTION
Do not tow a vehicle for more than 50 m in at-
tempt t

o start it. There is risk of damage to
the catalytic converter. Note
● Ple a

se observe related legal requirements.88

Self-help
●
Swit c
h on the hazard warning lights of both
vehicles. However, observe any regulations
to the contrary.
● The tow rope must not be twisted. Other-
wise the fr
ont tow line anchorage could be
pulled off the vehicle. Indications for tow-starting
Vehicle's should not generally be tow-star-
ted.
The jump s

tart should be used instead
›››  page 61.
For technical reasons, towing the following
vehicles is not allowed:
● Vehicles with an automatic gearbox.
● If the vehicle battery is discharged, be-
cau se in

vehicles with the Keyless Access
locking and ignition system the steering re-
mains locked and the electronic parking
brake cannot be deactivated nor can the elec-
tronic lock of the steering column be re-
leased if they are activated.
● If the battery is flat, it is possible that the
engine contr
ol units may not operate correct-
ly.
However, if the vehicle must absolutely be
tow-started (in the case of manual gearbox-
es):
● Engage the 2nd or 3rd gear. ●
Keep the clut
ch pressed down.
● Switch on the ignition and the hazard warn-
ing lights.
● Once both

vehicles are moving, release the
clutc
h.
● Once the engine starts, press the clutch
and diseng
age the gear to avoid colliding
with the towing vehicle. Note
The vehicle can only be tow-started if the
electr onic

parking brake and, if appropriate,
the electronic lock of the steering column are
deactivated. If the vehicle has no power sup-
ply or there is an electric system fault, the
engine must be tow-started to deactivate the
electronic parking brake and the electronic
lock of the steering column. Anchoring the front tow line

Note
● Never l e
ave any valuable items in the vehi-
cle unattended. Even a locked vehicle is not a
safe.
● If the diode on the driver door sill lights up
for about 30 sec
onds when the vehicle is
locked, the central locking system or anti-
theft alarm* is not working properly. You
should have the fault repaired at a SEAT Offi-
cial Service or specialised workshop.
● The vehicle interior monitoring of the anti-
theft a
larm* system will only function as in-
tended if the windows and the sunroof* are

Spare key
To obtain a spare key and other vehicle keys,
the vehicle chassis number is required.
Each new key contains a microchip which
must be coded with the data from the vehicle
electronic immobiliser. A vehicle key will not
work if it does not contain a microchip or the
microchip has not been encoded. This is also
true for keys which are specially cut for the
vehicle. »

● If the v

ehicle battery has little or no charge,
or the vehicle key battery is almost or entire-
ly out of charge, you will probably not be able
to lock or unlock the vehicle with the Keyless
Access system. The vehicle can be unlocked
or locked manually ››› page 87.
● To control the proper locking of the vehicle,
the rele
ase function is disabled for approx. 2
seconds.
● If the message Keyless access system
faulty is di

splayed on the screen of the
dash panel, abnormalities may occur in the
operation of the Keyless Access system. Con-
tact a specialised workshop. SEAT recom-
mends visiting a SEAT dealership for this.

tainment sy
stem for the mirrors, the exterior
mirrors will unfold and the surround lighting
will come on when unlocking the vehicle us-
ing the sensor surface on the driver and pas-
senger door handles ››› page 141.
● If there is no valid key inside the vehicle or
the syst
em 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 sen sor

s are very dirty, e.g. have a lay-
er of salt, how the sensors on the door han-
dles operate may be affected. In this case,
clean the vehicle.

ating the alarm. ●
The turn sign
al light will flash once on clos-
ing and activating the alarm.
When does the system trigger an alarm?
The anti-theft alarm siren will be triggered for
about 30 seconds accompanied by sound
and optical (flashing) warning signals and
will be repeated about ten times when the
vehicle is locked and the following unauthor-
ised actions are attempted:
● Opening a door that is mechanically un-
locked u
sing the vehicle key without switch-
ing on the ignition in the next 15 seconds (in
certain markets, such as the Netherlands,
there is no 15 second waiting time and the
alarm is activated immediately on opening
the door).
● A door is opened.
● The bonnet is opened.
● The rear lid is opened.
● When the ignition is switched on with a
non-authorised k
ey.
● When the vehicle battery is disconnected.
● Movement inside the vehicle (in vehicles
with interior monit
oring ››› page 126).
● When the vehicle is towed (in vehicles with
anti-tow sy
stem ››› page 126).
● When the vehicle is raised (in vehicles with
anti-to w sy

stem ››› page 126). ●
When the v ehic

le is transported on a ferry
or by rail (vehicles with an anti-tow system or
vehicle interior monitoring ››› page 126).
● When a trailer connected to the anti-theft
alarm sys
tem is disconnected.
How to turn OFF the alarm
Unlock the vehicle with the unlocking button
on the key or turn on the ignition with a valid
key. Note
● Aft er 28 d

ays, the indicator light will be
switched off to prevent the battery from ex-
hausting if the vehicle has been left parked
for a long period of time. The alarm system
remains activated.
● If, after the audible warning goes off, an-
other monitored ar
ea is accessed (e.g. the
rear lid is opened after a door has been
opened), the alarm is triggered again.
● The anti-theft alarm is not activated when
the vehic
le is locked from within using the
central locking button  .
● If the driver door is unlocked mechanically
with the k ey

, only the driver door is unlocked,
the rest of the doors remain locked. Only
when the ignition has been turned on will the
other doors be available - but not unlocked -
and the central locking button will be activa-
ted. 124

Opening and closing
●
If the v
ehicle battery is run down or flat
then the anti-theft alarm will not operate cor-
rectly.
● Vehicle monitoring remains active even if
the batter
y is disconnected or not working for
any reason.
● The alarm is triggered immediately if one of
the batter
y cables is disconnected while the
alarm system is active. Vehicle interior monitoring and anti-
to
w sy

stem* It is a monitoring or control function incorpo-
r
at
ed in the anti-thef

t alarm* which detects
unauthorised vehicle entry by means of ultra-
sound.
Activation
– It is automatically switched on when the
anti-theft al

arm is activated.
Deactivation – Open the vehicle with the key, either me-
chanic

ally or by pressing the  button on
the r emot
e c
ontrol. The time period from
when the door is opened until the key is in-
serted in the contact should not exceed 15
seconds, otherwise the alarm will be trig-
gered. –
Pres
s the button  on the remote control
tw ic
e.
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 monitoring 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). ●
Panoramic/ti lting sunroof open (partially or
completely).
● 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
all the doors are closed (including the rear
lid). 125
