Opening and closing
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
The interior monitoring only operates correctly if the vehicle is completely
closed. Please observe legal requirements when doing so.
The following cases may cause a false alarm:
● opened windows (partially or fully)
● panoramic/tilting sunroof open (partially or completely).
● movement of objects inside the vehicle, such as loose papers, items
hanging from the rear vision mirror (air fresheners), etc.
Note
● If the vehicle is relocked and the alarm is activated without the volumet-
ric sensor function, 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 volumetric sensor, this will be in-
dicated by a flashing of the warning lamp on the driver door when the vehi-
cle is opened. The flash is different to the flash indicating the alarm is acti-
vated.
● The vibration of a mobile phone left inside the vehicle may cause the ve-
hicle interior monitoring alarm to trigger, as both sensors react to move-
ments and shakes inside the vehicle.
● If on activating the alarm, any door or the rear lid is open, only the alarm
will be activated. The vehicle interior monitoring and the anti-tow system
will only be activated once all the doors are closed (including the rear lid). Deactivating the vehicle interior monitoring and tow-away
protection

monitoring/tow-away
protection button
When the vehicle is locked, the alarm will be triggered if move-
ments are detected in the interior (e.g. by animals) or if the vehi-
cle's inclination is changed (e.g. during transport). You can prevent
the alarm from being triggered accidentally by switching off the ve-
hicle interior monitoring and/or tow-away protection.
– To switch off the vehicle interior monitoring and tow-away pro-
tection, switch off the ignition and press button ⇒ Fig. 54. The
button will light up.
– When the vehicle is locked now, the vehicle interior monitoring
and the tow-away protection are switched off until the next time
the door is opened.
If the anti-theft security system (Safelock)* ⇒ page 87 is switched off, the
vehicle interior monitoring and the tow-away protection are automatically
switched off. 

Opening and closing
As a general rule, when the driver door is locked all other doors are locked.
When the vehicle is unlocked manually, only the driver door opens. Please
observe the instructions relating to the anti-theft alarm system ⇒ page 87.
● Unfold the vehicle key shaft ⇒ page 89.
● Insert the key shaft into the opening in the cover on the driver door han-
dle from below ⇒ Fig. 55 (arrow) then remove the cover upwards.
● Insert the key shaft into the lock cylinder to unlock or lock the vehicle.
Unlocking notes:
● The anti-theft alarm will remain active when vehicles are unlocked. How-
ever, the alarm will not yet be triggered ⇒ page 87.
● After the driver door is opened, you have 15 seconds to switch on the
ignition. After 15 seconds, the alarm is triggered.
● Switch the ignition on. When the ignition is switched on, the electronic
immobiliser recognises a valid vehicle key and deactivates the anti-theft
alarm system.
Note
The anti-theft alarm is not activated when the vehicle is locked manually us-
ing the key shaft ⇒ page 87. Manual locking of passenger door in an emergency
If the central locking system should fail to work at any time,
the passenger door will have to be locked separately.
Fig. 56 Locking the door
manually
A mechanical locking device (only visible when the door is open) is
provided on the front passenger door.
– Pull the cap out of the opening.
– Insert the key in the inside slot and turn it to the right as far as
it will go (if the door is on the right side) or to the left (if the
door is on the left side).
Once the door has been closed it can no longer be opened from the outside.
Pull the interior door handle once to unlock and open the door. 

260Checking and refilling levels
WARNING
● Brake fluid should be stored in the closed original container in a safe
place out of reach of children. Risk of poisoning!
● If the brake fluid is left in the system for too long and the brakes are
subjected to heavy use, vapour bubbles may form in the brake system.
This would seriously affect the efficiency of the brakes and the safety of
the vehicle. This may cause an accident.
CAUTION
Brake fluid should not come into contact with the vehicle paintwork, as it is
abrasive. 
Battery General information
The battery is located in the engine compartment and is almost mainte-
nance-free. It is checked as part of the Inspection Service. Nevertheless,
check the terminals are clean and have the correct tightening torque, espe-
cially in summer and winter.
Disconnecting the battery
The battery should only be disconnected in exceptional cases. When the
battery is disconnected, some of the vehicle's functions are “lost” ( ⇒ table
on page 260). These functions will require resetting after the battery is re-
connected.
Deactivate the anti-theft alarm* before you disconnect the battery Other-
wise the alarm will be triggered.

ESC warning lampAfter driving for a few metres, the
warning lamp goes out again.
If the vehicle is not used for long periods
The vehicle has a system for monitoring the current consumption when the
engine is left unused for long periods of time ⇒ page 226. Some functions,
such as the interior lights, or the remote door opening, may be temporarily
disabled to prevent the battery from running flat. These functions will come
back on as soon as the ignition is switched on and the engine started.
Winter conditions
During the winter, the starting power may be reduced, and if necessary, the
battery should be charged ⇒

Important safety warnings for handling a vehicle battery
All work on batteries requires specialist knowledge. Please refer to a SEAT
Official Service or a workshop specialising in batteries: risk of burns or ex-
ploding battery!
The battery must not be opened. Never try to change the fluid level of the
battery. Explosive gas is released from the battery that could cause an ex-
plosion. 
