Steering Inf ormation r
elating to different ve-
hicle processes. Electro-mechanical power steering adapts
el
ectr

onically to the speed of the car, torque
and steering angle.
Even if the power steering fails or the engine
is stopped, it is possible to continue to rotate
the steering wheel as long as the key remains
in the ignition, but more force must be ap-
plied.
Progressive steering
Depending on the vehicle’s features, it may or
may not incorporate a progressive steering
system.
In city traffic you do not need to turn so much
on parking, manoeuvring or in very tight turns.
On the road or on the motorway, progressive
steering transmits, for example, in bends, a
sportier, more direct and noticeably more dy-
namic driving sensation. Control lamp v

specialist assistance. The control lamp should light up for a few
seconds when the ignition is s

es.

Driver assistance systems
Activate or deactivate the dodge and turn
assist ant
The dodge and t
urn assistance systems can
be activated or deactivated in the infotain-
ment system using the function button  > Driver assistance > Front Assist
››› page 96.
The system will store the setting for the next
time the ignition is switched on.
SEAT recommends having the dodge and
turn assistance systems activated except in
the exceptions described in section
››› page 253.
Deactivating Front Assist temporarily in
the following situations
In the following situations the Front Assist
should be deactivated due to the system's
limitations:

approach from behind, such as cars
››› Fig. 193.
If a critical situation is detected when the
door is opened, it will be alerted by an acous-
tic signal on the door speaker of the corre-
sponding side ››› Fig. 194
. Additionally, the
control lamp of the lane departure warning of
the corresponding door will flash. If the door
has already been opened and another road
user has been detected in a critical situation,
the control lamp of the lane departure warn-
ing on the corresponding side will light up
permanently.
The brightness of the door opening warning
indication cannot be adjusted.
When you want to access the vehicle for the
first time, with the doors closed and locked,
the function will be available 3 minutes after
the first opening of any of the doors. The
function will continue to be available as long
as the vehicle has the ignition connected and
is not moving.
After switching off the ignition, the function
will remain available for approximately 3 mi-
nutes. After that time, the control lamps will
light up indicating the deactivation of the
function. WARNING

slope.
The engine rotates “correctly”.
The Auto Hold function is automatically
turned off if the following conditions are
met: If any of the conditions mentioned on
››› page 277, Conditions for keeping
the vehicle stationary with the Au-
to Hold function are no longer met.
If the engine is running irregularly or an

ows:
Grey segments: the obstacle is more
than approx. 30 cm away from the path
or in the direction opposite to travel.
They are also displayed when the elec-
tronic parking brake is activated.
Yellow segments: the obstacles lie on
the vehicle’s path and are at a distance
of less than approx. 30 cm away.
Red segments: obstacles are less than
approx. 30 cm away.
A wake will indicate the anticipated forward
or backward trajectory, depending on the en-
gaged gear. –

– If an obstacle is located in the vehicle’s way,
the corresponding audibl

When the penultimate segment is displayed,
the vehicle has reached the collision zone. In
the collision zone, the obstacles are repre-
sented in red (including those out of the
path). Stop the vehicle! ››› in Introduction

Practical tips
Energy management Optimisation of the st ar
ting ca-
pacity The power management controls the distri-
bution of el
ectrical ener

gy and thus helps to
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 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
registers the condition of the battery. Sensors detect the battery voltage, battery current
and batt
ery t

emperature. 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
convenience functions, such as remote vehi-
cl e opening, may not be av
ailable 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 electrical power. If you notice, for instance, that the seat heating* or the rear window
heater is not w
orking, 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
