2014 Seat Leon 5D ECU

Operation
The vehicle keys or new spare keys can be
obtained from a SEAT Official Service, a spe-
cialised workshop or an approved key service
qualified to create this kind of key.
New keys or spare keys must be synchron-
ised before use ››› page 87. CAUTION
All of the vehicle keys contain electronic com-
ponents. Protect them from damage, impacts
and humidity. Note
● Only use the key button when you require
the corresponding function. Pushing the but-
ton unnecessarily could accidentally unlock
the vehicle or trigger the alarm. It is also pos-
sible even when you are outside the radius of
action.
● Key operation can be greatly influenced by
overlapping radio signals close to the vehicle
working in the same range of frequencies, for
example, radio transmitters or mobile tele-
phones.
● Obstacles between the remote control and
the vehicle, bad weather conditions and dis-
charged batteries can considerably reduce
the range of the remote control.
● If the buttons of the vehicle key are press-
ed ››› Fig. 91 or ››› Fig. 92 or one of the central
locking buttons ››› page 85 is pressed re-
peat
edly in short succession, the central
locking briefly disconnects as protection against overloading. The vehicle is then un-
locked. Lock it if necessary.

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/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 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 vehicle 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 is 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). Deactivating the vehicle interior

You can prevent the alarm from being trig-gered accidentally by switching off the vehi-
cle interior monitoring and/or tow-away pro-
tection.

The essentials

Transport and practical equipment
●
For the rear seat seat belts to offer the nec-
essary protection all the parts of the rear
backrest must be properly engaged. This is
particularly important in the case of the cen-
tre rear seat. If someone is seated in a seat
whose backrest is not properly engaged they
will fly forward, along with the backrest, dur-
ing an accident or a sudden driving or braking
manoeuvre.
● A red signal on the button 2 warns that
the backrest is not engaged. Always check
that the red marking is not visible when the
backrest is in the upright position.
● When the rear seat backrest is lowered or is
not properly engaged nobody else can travel
in the corresponding seats (not even a child). CAUTION
Serious damage can be caused to the vehicle
and other objects if the rear seat backrest is
lowered or lifted without due care and atten-
tion.
● Before lowering the rear seat backrest, al-
ways adjust the front seats so that neither
the head restraints nor the cushions of the
rear backrest can hit them. Transport and practical

Storing objects Loading the luggage compartment All luggage and other loose objects must be
safely secured in the luggage compartment.
Unsecured objects which shift back and forth
could impair the driving safety or driving
characteristics of the vehicle by shifting the
centre of gravity.
– Distribute the load evenly in the luggage
compartment.
– Place heavy objects as far forward as possi-
ble in the luggage compartment.
– Place the heavy objects first.
– Secure heavy objects to the fitted fastening
rings ›››
page 119 . WARNING
● Loose luggage and other objects in the lug-
gage compartment could cause serious inju-
ries.
● Always stow objects in the luggage com-
partment and secure them on the fastening
rings.
● Use suitable straps to secure heavy ob-
jects.
● During sudden manoeuvres or accidents,
loose objects can be thrown forward, injuring
vehicle occupants or passers-by. This in-
creased risk of injury will be further increased if a loose object is struck by an inflating air-
bag. If this happens, objects may shoot out-
ward like a missile. Risk of fatal injury.
●
Please note that the centre of gravity may
shift when transporting heavy objects; this
may affect vehicle handling and lead to an ac-
cident. Therefore, it is essential to adjust
your speed and driving style accordingly, to
avoid accidents.
● Never exceed the allowed axle weights or
allowed maximum weight. If said weights are
exceeded, the driving characteristics of the
vehicle may change, leading to accidents, in-
juries and damage to the vehicle.
● Never leave your vehicle unattended, espe-
cially when the rear lid is open. Children
could climb into the luggage compartment,
closing the door behind them; they will be
trapped and run the risk of death.
● Never allow children to play in or around
the vehicle. Close and lock all the doors and
rear lid when you leave the vehicle. Before
you lock the vehicle, make sure that there are
no adults or children in the vehicle. Note
● Air circulation in the vehicle helps reduce
fogging of the windows. Used air escapes
through ventilation slits in the side trim of
the luggage compartment. Ensure that the
ventilation slots are never covered.
● Straps for securing the load to the fasten-
ing rings are commercially available. Luggage compartment cover
