Keyless Access is a key-free locking and igni-
tion system to unlock and lock the vehicle
without actively using its key. To do this, all
that is required is to have a valid vehicle key in
the detection area where you are attempting
to access the vehicle

Opening and closing
The vehicle interior monitoring and the anti-
t o
w syst
em are automatically switched on
again next time the vehicle is locked.
The vehicle interior monitoring and anti-tow
sensor (tilt sensor) are automatically switch-
ed 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 system, 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
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:

Air conditioning
Functioning mode of automatic air recircu-
l ation (air conditioning menu)
With the aut omatic air r
ecirculation mode ac-
tivated, the entry of fresh air into the cabin in-
terior is enabled. If the system detects a high
concentration of hazardous substances in the
ambient air, air recirculation mode is switched
on automatically. When the level of impurities
drops to within a normal range, recirculation
mode is switched off.
The system is unable to detect unpleasant
smells.
The air recirculation will not connect auto-
matically in versions without humidity sensor
and in the following external conditions:

Instructions for navigation When the Infotainment system is unable to re-
ceive any dat
a fr
om GPS satellites (due to a
dense tree canopy, underground car park),
navigation can still continue using the vehicle
sensors.
Possible limitations in navigation
In areas that are not or are only partially digi-
tised on the data storage device (e.g. insuffi-
cient definition of one-way streets and road
categories), the Infotainment system will still
attempt to provide route guidance.
Navigation area and updating navigation
data
Roads and streets are subject to constant
change (e.g. new roads, changes to street
names and building numbers). Therefore, if
the navigation data is not updated, then er-
rors or inaccuracies may occur during guid-
ance.
SEAT recommends updating navigation data
on a regular basis. Up to date navigation data
can be downloaded from www.seat.com or
acquired at a SEAT dealer. Updating and using navigation da-
ta fr

d  Only available for the model: Navi System
The Inf ot

ainment system always requires the
navigation data that is currently valid for this
unit in order to allow all functions to be used
in full. Using an old version may lead to errors
during navigation.
Updating navigation data
The current navigation data can be downloa-
ded in the internet at www.seat.com and stor-
ed in a SD card compatible with the unit.
Suitable SD Cards can be acquired at SEAT
dealerships.
The procedure is described on the internet at
www.seat.com.

Driving
Electronic torque management (XDS)
When t aking a curv
e
, the driveshaft differen-
tial mechanism allows the outer wheel to turn
at a higher speed than the inner wheel. In this
way, the wheel that is turning faster (outer
wheel) receives less drive torque than the in-
ner wheel. This may mean that in certain sit-
uations the torque delivered to the inner
wheel is too high, causing the wheels to spin.
On the other hand, the outer wheel is receiv-
ing a lower drive torque than it could transmit.
This causes an overall loss of lateral grip on
the front axle, resulting in understeer or
“lengthening” of the trajectory.
The XDS system can detect and correct this
effect via the sensors and signals of the ESC.
Via the ESC, the XDS will brake the inside
wheel and counter the excess driving torque
of that wheel. This means that the driver

Start and driving
Since the luggage rack increases the aer o-
dynamic dr ag
of the vehicle, you should re-
move it when not needed. At speeds of
100-120 km/h (62-75 mph), this will save 12%
of fuel.
Save electrical energy
The engine drives the alternator, thereby
generating electricity. This implies that any
increase in power consumption also increa-
ses fuel consumption! For this reason, switch
off any unneeded electrical devices. Devices
that use a lot of electricity includes the blow-
er at a high setting, the rear window heating
or the seat heating*.
Power management
This system helps to ensur
e relia-
ble starting The power management controls the distri-
bution of el
ectrical ener
gy and thus helps t

o
ensure that there 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 v

ehicle 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
registers the condition of the battery. 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 r
eliably.
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
