 page 69.
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 could 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.
● Switch on the hazard warning lights of both
vehicl
es. However, observe any regulations
to the contrary. 98

Self-help
●
The to w r
ope must not be twisted. Other-
wise the front 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 70.
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 clutch pressed down.
● Switch on the ignition and the hazard warn-
ing lights. ●
Once both v
ehicles are moving, release the
clutch.
● 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

the towline anc

horage is screwed on the right
part of the front bumper.
– To open the cover, press the left side.
– Take the towline anchorage out of the vehi-
cle t

ool kit ››› page 95.

connection as

far as it will go ››› Fig. 98 and
tighten with the wheel brace.
After use, unscrew the towline anchorage
and fit the cover back on the bumper. Put the
towline anchorage back in the vehicle tool
kit. The towline anchorage should always be
kept in the vehicle.

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
closed. Car key

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.

s. CAUTION
The sensor surfaces on the door handles
cou l

d engage if hit with a water jet or high
pressure steam if there is a valid vehicle key
in the proximity. If at least one of the electric
windows is open and the sensor surface B (arrow) on one of the handles is activated
continuou
s

ly, all windows will close. Note
● 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 97.
● To control the proper locking of the vehicle,
the rele
ase function is disabled for approx. 2

ing the sensor surface on the driver and pas-
senger door handles ››› page 150. ●
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

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.

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 key
, 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. ●
If the v

ehicle battery is run down or flat
then the anti-theft alarm will not operate cor-
rectly.
