Anti-theft alarm system*
Description of anti-theft alarm system*
The anti-theft alarm triggers if unauthorised movements are
detected around the vehicle.
The anti-theft alarm makes it more difficult to break into the vehicle or steal
it. Audible and visible alarms are triggered if the vehicle is opened using
the key, or if unauthorised access to the vehicle is forced.
The anti-theft alarm system is automatically connected on locking the vehi-
cle. The system is then primed.
When does the system trigger an alarm?
The system triggers an alarm if the following unauthorised actions are car-
ried out when the vehicle is locked:
● Mechanical opening of the vehicle with the vehicle key
● Opening a door
● Opening the bonnet
● Opening the tailgate
● Switching on the ignition
● Movements in the vehicle interior
● Undue manipulation of the alarm
● Battery handling
The acoustic signals sound and the turn signals flash for approx. 30 sec-
onds. This may be repeated up to 10 times depending on the country.
Opening the doors mechanically (emergency opening)
If the remote control function fails, you will have to use the key to unlock the
vehicle. This is done as follows: ●
Unfold the key by pressing the button shown by the (arrow).
● Use the lock on the driver door to unlock the vehicle. The anti-theft
alarm system remains active, but an alarm is not triggered immediately.
● Switch on the ignition within 15 seconds. When the ignition is switched
on, the electronic immobiliser recognises a valid vehicle key and deacti-
vates the anti-theft alarm system. If you do not switch on the ignition within
15 seconds, the alarm is triggered.
Opening all the doors in manual mode
In vehicles without alarm, when opening the driver door manually all the
doors are opened.
How to switch the alarm off
When the vehicle is unlocked via the unlocking button of the remote control
or when the key is inserted in the ignition lock.
Note
● If, after the alarm goes off, another monitored area is accessed (e.g. the
tailgate is opened after a door has been opened), the alarm is triggered
again.
● Vehicle monitoring remains active even if the battery is disconnected or
not working for any reason.
● The alarm is triggered immediately if one of the battery cables is discon-
nected while the alarm system is active. 
Volumetric sensor*
Monitoring or control function incorporated in the anti-theft
alarm* which detects unauthorized vehicle entry by means
of ultrasound.
The system consists of 3 sensors, 2 emitters and a receptor. 

Unlocking and locking
WARNING
● Always close the tailgate properly. Risk of accident or injury.
● The tailgate must not be opened when the reverse or rear fog lights
are lit. This may damage the tail lights
● Do not close the tailgate by pushing it down with your hand on the
rear window. The glass could smash. Risk of injury!
● Ensure the tailgate is locked after closing it. If not, it may open unex-
pectedly while driving.
● Never allow children to play in or around the vehicle. A locked vehicle
can be subjected to extremely high and low temperatures, depending on
the time of year, thus causing serious injuries/illness. It could even have
fatal consequences. Close and lock both the tailgate and all the other
doors when you are not using the vehicle.
● Closing the tailgate without observing and ensuring it is clear could
cause serious injury to you and to third parties. Make sure that no one is
in the path of the tailgate.
● Never drive with the tailgate open or half-closed, exhaust gases may
penetrate into the interior of the vehicle. Danger of poisoning!
● If you only open the tailgate, do not leave the key inside. The vehicle
will not be opened if the key is left inside.
 Emergency opening
This allows the vehicle to be opened if the central locking
does not operate (for example, if the battery is flat)
Fig. 66 Tailgate: emer-
gency open
There is a groove in the luggage compartment allowing access to
the emergency opening mechanism.
Opening the tailgate from inside the luggage compartment
– Insert the key in the groove and unlock the locking system, turn-
ing the key from right to left, as shown by the arrow ⇒ fig. 66.

Unlocking and locking
Note
If the window is not able to close because it is stiff or because of an ob-
struction, the window will automatically open again ⇒ page 111. If this
happens, check why the window could not be closed before attempting to
close it again. 
One-touch opening and closing
One-touch opening and closing means you do not have to
hold down the button.
One-touch closing
– Pull up the window button briefly up to the second position. The
window closes fully.
One-touch opening
– Push down the window button briefly up to the second position.
The window opens fully.
Reset the automatic closing function for the front side windows
and the automatic opening for all windows
– Close all windows.
– Use the key to lock the vehicle from outside and hold the key in
the lock position for at least one second. The one-touch func-
tion is now ready for operation.
The buttons ⇒ fig. 67 1
and 2 have two levels for opening the window
and two for closing it. This makes it easier to open and close windows to the
desired position. One-touch closing does not work when the ignition has been switched off,
even if the key is in the ignition.
The automatic open and close function will not work if the battery has been
temporarily disconnected, or if the battery is flat. The function then has to
be reactivated.
The one-touch function and roll-back function will not work if there is a mal-
function in the electric windows. Contact an Authorised Service Centre.

Roll-back function
The windows have a roll-back function. This reduces the risk
of injuries when the windows are closing.
● If a window is obstructed when closing automatically, the window stops
at this point and lowers immediately ⇒ 
.
● If this happens, check immediately (within 10 seconds) why the window
could not be closed before attempting to close it again. After 10 seconds
the normal automatic function resumes.
● If the window is still obstructed, the window will stop at this point.
● If there is no obvious reason why the window cannot be closed, try to
close it again within 5 seconds.
If you wait longer than 5 - 10 seconds, the window will open fully when you
operate one of the buttons. One-touch closing is reactivated.
The one-touch function and roll-back function will not work if there is a mal-
function in the electric windows. Contact an Authorised Service Centre. 

3. Switch the engine off.
4. Apply the handbrake.
5. On a manual gearbox engage 1st gear. On an automatic, move the selector lever to P.
6. Use the warning triangle to draw the attention of other road users to your vehicle.
7. Always take the vehicle key with you when you leave the vehi- cle.
Switch on the hazard warning lights to warn other road users, for example
when:
● reaching the tail end of a traffic jam,
● there is an emergency
● your vehicle breaks down due to a technical fault,
● you are towing another vehicle or your vehicle is being towed.
All turn signals flash simultaneously when the hazard warning lights are
switched on. That is that the two turn signal turn signal lamps   and the
turn signal lamp in the switch  will flash at the same time. The hazard
warning lights also work when the ignition is switched off.
Emergency braking warning
If the vehicle is braked suddenly and continuously at a speed of more than
80 km/h, the brake light flashes several times per second to warn vehicles
driving behind. If you continue braking, the hazard warning lights will come
on automatically when the vehicle comes to a standstill. They switch off au-
tomatically when the vehicle starts to move again.
WARNING
● The risk of an accident increases if your vehicle breaks down. Always
use the hazard warning lights and a warning triangle to draw the atten-
tion of other road users to your stationary vehicle.
● Never park where the catalytic converter could come into contact with
inflammable materials under the vehicle, for example dry grass or spilt
petrol. This could start a fire!
Note
● The battery will run down if the hazard warning lights are left on for a
long time, even if the ignition is switched off.
● The use of the hazard warning lights described here is subject to the rel-
evant statutory requirements. 

Driving
If the engine does not start immediately, switch the starter off after 10 sec-
onds and try again after half a minute. If the engine still does not start, the
fuel pump fuse should be checked ⇒ page 250, Fuses.
WARNING
● Never start or run the engine in unventilated or closed rooms. The ex-
haust fumes contain carbon monoxide, an odourless and colourless poi-
sonous gas. Risk of fatal accidents. Carbon monoxide can cause loss of
consciousness. It can also cause death.
● Never leave the vehicle unattended if the engine is running.
● Never use “cold start sprays”, they could explode or cause the engine
to run at high revs. Risk of injury.
CAUTION
● When the engine is cold, you should avoid high engine speeds, driving
at full throttle and over-loading the engine. Risk of engine damage.
● The vehicle should not be pushed or towed more than 50 metres to start
the engine. Unburnt fuel could enter the catalytic converter and damage it.
● Before attempting to push-start or tow a vehicle in order to start it, you
should first try to start it using the battery of another vehicle. Note and fol-
low the instructions in ⇒ page 263, Jump-starting.
For the sake of the environment
Do not warm-up the engine by running the engine with the vehicle station-
ary. Start off immediately, driving gently. This helps the engine reach oper-
ating temperature faster and reduces emissions. Starting diesel engines
The engine can only be started using a genuine SEAT key
with its correct code.
– Move the gear lever to the neutral position and depress the
clutch pedal thoroughly and hold it in this position for the start-
er to turn the engine on.
– Turn the ignition key to the starting position.
– Turn the ignition key to position ⇒ fig. 117 1
. The indicator
lamp  will light for engine pre-heating.
– When the warning lamp turns off, turn the key to position 2
to
start the engine. Do not press the accelerator.
– Let go of the ignition key as soon as the engine starts, the start-
er motor must not be allowed to run on with the engine.
When starting a very cold engine, it may be a little noisy for the first few sec-
onds until oil pressure has built up in the hydraulic valve compensators.
This is quite normal, and no cause for concern.
If there are problems starting the engine, see the ⇒ page 263.
Glow plug system for the diesel engine
To avoid unnecessary discharging of the battery, do not use any other major
electrical equipment while the glow plugs are pre-heating.
Start the engine as soon as the glow plug warning lamp ⇒ page 83 goes
out.
Starting the engine after the fuel tank has been completely run dry
If the fuel tank has been completely run dry, it may take longer than normal
(up to one minute) to start the engine after refuelling with diesel fuel. This is
because the system must eliminate air first. 
