Operation
Changing the battery

Opening and closing
For the automatic raising function: pull the
butt on f
or the corr esponding windo
w up-
w
ards until it reaches the second position.
For the automatic lowering function: pull
the button for the corresponding window up-
wards until it reaches the second position.
Stop automatic movement: push or pull on
the button of the corresponding window.
Resetting one-touch opening and closing
The one-touch opening and closing function
is not active after the vehicle battery has
been disconnected or is flat and will have to
be reset.

Operation
Heated rear window  This only w orks when the engine is running
and s witches off aut

er a maxi-
mum of 10 minutes.
It should be switched off as soon as the glass
is demisted. By saving electrical power you
can also save fuel. To avoid possible damage to the battery, an
automatic temporary disconnection of this
function is possible
, coming back on when
normal operating conditions are re-establish-
ed.

After the engine is switched off the radiator

ven if
the ignition is switched off. It is also possi-
ble that the fan turns itself on once more if
the coolant temperature increases due to
the heat accumulated in the engine com-
partment or due to its prolonged exposure
to solar radiation. Electronic immobilizer
The electronic immobiliser prevents unau-
thorised persons fr
om driving the v

.
Inside the k

ey there is a chip that deactivates
the electronic immobiliser automatically
when the key is inserted into the ignition.
The electronic immobiliser will be activated
again automatically as soon as you pull the
key out of the ignition lock. For vehicles with
the “Keyless Access” system, the key has to
be outside the vehicle.
If the following message is shown on the in-
strument panel display: SAFE , the vehicle
cannot be started.
The engine can only be started using a genu-
ine SEAT key with its correct code. Note
A perfect operation of the vehicle is ensur-
ed if genuine SEAT keys are used. Emergency starting function

.Energy management
Optimisation of the starting ca-pacity The power management controls the distri-
bution of electrical energy and thus helps to
ensur
e that ther

e is always enough power
available to start the engine.
If a vehicle with a conventional electrical sys-
tem is left parked for a long time, the battery
will gradually lose its charge because certain
electrical devices, such as the electronic
gearbox lock continues to draw current even
when the ignition is off. In some cases there
may not be enough power available to start
the engine.
Your vehicle is equipped with an intelligent
power management system to control the
distribution of electrical energy. This signifi-
cantly improves reliability when starting the
engine, and also prolongs the useful life of the
battery.
The main functions incorporated in the power
management system are battery diagnosis,
residual current management and dynam-
ic power management. Battery diagnosis
The battery diagnosis function constantly
regist ers the condition of the batt

ery. Sensors
detect the battery voltage, battery current
and battery temperature. This enables the
system to calculate the current power level
and charge condition of the battery.
Residual current management
The residual current management reduces
power consumption while the vehicle is
parked. It controls the supply of power to the
various electrical devices while the ignition is
switched off. The system takes the battery di-
agnosis data into consideration.
Depending on the power level of the battery,
switch off the individual electrical devices
one after the other to prevent the battery
from losing too much charge and to ensure
that the engine can be started reliably.
Dynamic power management
While the vehicle is moving, this function dis-
tributes the available power to the various
electrical devices and systems according to
their requirements. The power management
ensures that on-board systems do not con-
sume more electrical power than the alterna-
tor can supply, and thus maintains the maxi-
mum possible battery power level. Note

Wheels
current they are using. This limits the amount
of po w
er consumed and helps t o ensur
e r
eli-
able starting even after a long period. Some
convenience functions, such as remote vehi-
cle opening, may not be available under cer-
tain circumstances. These functions will be
restored when you switch on the ignition and
start the engine.
With the engine switched off
For example, if you listen to the sound system
with the engine switched off the battery will
run down.
If the energy consumption means there is a
risk that the engine will not start, a text will
appear in vehicles with a driver information
system*.
This driver indicator tells you that you must
start the engine so that the battery can re-
charge.
When the engine is running
Although the alternator generates electrical
power, the battery can still become dis-
charged while the vehicle is being driven. This
can occur when a lot of power is being con-
sumed but only a small amount supplied, es-
pecially if the battery is not fully charged ini-
tially.
To restore the necessary energy balance, the
system will then temporarily shut off the elec-
trical devices that are using a lot of power, or reduce the current they are consuming. Heat-
ing systems in particular use a large amount
of el
ectrical power. If you notice, for instance,
that the seat heating* or the rear window
heater is not working, they may have been
temporarily switched off or regulated to a
lower heat output. These systems will be
available again as soon as sufficient electri-
cal power is available.
You may also notice that the engine runs at a
slightly faster idling speed when necessary.
This is quite normal, and no cause for con-
cern. The increased idling speed allows the
alternator to meet the greater power require-
ment and charge the battery at the same
time. Wheels
