2012 Seat Leon 5D warning light

95
Opening and closing
The vehicle interior monitoring and anti-tow sensor (tilt sensor) are auto-
matically switched 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 sys-
tem, 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
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 1)

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. 51. The
button will light up. 

fatal consequences. Close and lock both the rear lid and all the other
doors when you are not using the vehicle.
● Closing the rear lid without observing and ensuring it is clear could
cause serious injury to you and to third parties. Make sure that no one is



110Lights and visibility
WARNING
If the road is not well lit and other road users cannot see the vehicle well
enough or at all, accidents may occur.
● The automatic dipped beam control ( ) only switches on the dip-
ped beam when there are no changes in brightness, and not, for example
when it is foggy.
● Never drive with daytime lights if the road is not well lit due to weath-
er or lighting conditions. Daytime lights do not provide enough light to
illuminate the road properly or be seen by other road users.
● The rear lights do not come on with the daytime driving light. A vehi-
cle which does not have the rear lights on may not be visible to other
drivers in the darkness, in the case of heavy rain or in conditions of poor
visibility.
Note
In cold or damp weather conditions, the headlights, tail lights and turn sig-
nals may mist up inside temporarily. This is normal and in no way effects
the useful life of the vehicle lighting system. Hazard warning lights

The hazard warning lights are used to draw the attention of
other road users to your vehicle in emergencies.

Lights and visibility
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:
● 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. 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 (50 mph), 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 automatically 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. 
Main beam assist*
Main beam assist (Light Assist)
The main beam assist operates, within the limits of the system and depend-
ing on the environmental and traffic conditions, as of a speed of 60 km/h
(40 mph) when it switches on automatically, and is then deactivated again
below 30 km/h (20 mph) ⇒ 
. This is managed via a camera situated on
the base of the interior rear vision mirror.
The main beam assist generally detects illuminated areas and deactivates
the main beam when passing through a town, for example. 
