Driving
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

Start and driving
Description Depending on the equipment fitted in the ve-
hicl
e
, SEAT Drive Profile can operate on the
following functions:
Engine
Depending on the profile selected, the engine
responds more quickly or smoothly to the ac-
celerator being pressed. When the Eco pro-
file is selected, the Start-stop function is acti-
vated.
In vehicles with automatic transmission, the
gear change timing is changed to put the
changes at higher or lower revolutions. The
Eco profile activates the Inertia function,
thereby reducing consumption. The rest of
the driving profiles will activate the inertia use
function when the selector lever is not in the S
position, depending on how the accelerator
pedal is released ››› page 234
. When the ve-
hicle is turned on again, the function is activa-
ted by default to reduce consumption.
With manual transmission, the Eco profile
changes the gear change recommendations
to facilitate more efficient driving.
Dynamic chassis control (DCC)*
The DCC continuously adapts the damping
of the suspension system to the characteris-
tics of the road surface and the driving situa-
tion (speed, acceleration and steering wheel angle) according to the selected driving pro-
fil
e

. The vehicle's dynamic behaviour is also
adapted to improve grip on curves and turn-
ing capacity. Within the Individual profile you
can also adjust the DCC level in a custom-
ised manner.
In the event of a fault in the DCC, the follow-
ing message is displayed on the instrument
screen Fault: shock absorber regula-
tion
Steering
The power steering varies its driving modes
and adapts to the profile selected, thus offer-
ing the best behaviour for each situation.
Air conditioning
The Climatronic can operate in Eco mode
with particularly limited consumption.
Adaptive Cruise Control (ACC)*
Depending on the driving profile, the perform-
ance of the ACC varies, to allow more sporty
acceleration and braking or a more respect-
ful fuel consumption.
PreCrash system
The PreCrash system adapts according to
the selected configuration. The Sport driving
profile has specific settings to adapt to driv-
ing characteristics ››› page 24
. Setting the driving profile There are several ways to select a driving
pr
ofil

e using the infotainment system:

Driver assistance systems
Limitations
This syst em does not r
eact to objects that
cross transversely or to animals. The basic
limitations of the Front Assist must also be
taken into account ››› page 251
.
Turn assist Turn assist can avoid a collision with a vehicle
appr
oaching in the opposit

e direction, by
braking the vehicle itself when the intention is
to turn.
This system is active up to 15 km/h (9 mph).
Limitations
The turn-off assist function is available if you
have indicated your intention to turn by acti-
vating the turn signal, you have turned the
steering wheel and the turning path has star-
ted.
It only reacts to vehicles that are in the path
of the vehicle (not to animals, people, etc.).
The basic limitations of the Front Assist must
also be taken into account ››› page 251

ain circumstances,
some of the reactions may be inappropriate
from the driver's standpoint. So pay attention
in order to intervene if necessary.
The following conditions may cause the
Front Assist not to react or to do so too
late:

e xt
end or reactivate this warning by pressing
the button  or, depending on your vehicle’s
equipment, by grabbing the steering wheel.
During this time, the vehicle will move off
again if the vehicle in front moves forwards.

to start is not longer displayed, once the
vehicle in front has moved off:

Driver assistance systems
Lane Assist* Intr oduction The Lane Assist System helps the driver
st
ay in his/her l
ane within the physical lim-
its of the system. This function is not suita-
ble and is not designed to keep the vehicle
automatically in the lane.
Using the camera located in the windscreen,
the Lane Assist system detects the limits (lane
lines) dividing the lanes in which the vehicle is
travelling. If the vehicle gets too close to the
detected lane limits, the system alerts the
driver through a corrective motion of the
steering wheel. The driver can cancel the
steering corrective action at any time.
No warning is produced with the turn signals
activated, given that the Lane Assist system
understands that a lane change is required.
System limits
Use the Lane Assist system only on large,
well-maintained motorways and highways.
The system is not available under the follow-
ing conditions:

Driving
the driver take control of the vehicle. To do
this, it emits optical and acoustic w arnings
and causes br
aking jolts. The seat belt is
tightened (depending on the equipment). The
system slows down the vehicle and keeps it in
its lane.
You can cancel the adjustment at any time
by moving the steering wheel, over-acceler-
ating or braking.
While the emergency assistant is in operation,
other road users are warned as follows:

Braking and parking
Brake assist systems Electronic Stability Control (ESC)
The ESC helps t
o impr
ove safety. It reduces
the tendency to skid and improves the stabili-
ty and roadholding of the vehicle. The ESC
detects critical handling situations, such as
vehicle understeer or oversteer, or wheelspin
on the driving wheels. It stabilises the vehicle
by braking individual wheels or by reducing
the engine torque. The warning lamp will
flash on the instrument panel when the ESC is
intervening !.
The ESC includes the anti-lock brake system
(ABS), the hydraulic brake assist (HBA), the
traction control system (TCS), electronic dif-
ferential lock (EDS), electronic torque control
(XDS) and the tractor-trailer sway mitiga-
tion*.
ESC also helps stabilise the vehicle by
changing the torque.
The TCS can be deactivated when wheel
spin is desirable ››› page 281
.
Anti-lock brake system (ABS)
ABS prevents the wheels from locking up un-
der braking until the vehicle has reached a
virtual standstill. You can continue to steer the
vehicle even when the brakes are on full.
Keep your foot on the brake pedal and do not
pump the brakes. You will feel the brake pedal
pulsate while the ABS is working. If the running gear or brake system is modi-
fied, the eff
ectiv

eness of the ABS could be se-
verely limited.
Hydraulic Brake Assist (HBA)
The brake assist system can reduce the re-
quired braking distance. The braking force is
automatically boosted if you press the brake
pedal quickly in an emergency. You must
keep pressing the brake pedal until the dan-
ger has passed.
Traction control (TCS)
In the event of the wheels spinning, the TCS
reduces the engine torque to adapt to the
road condition. This helps the car to start
moving, accelerate or climb a gradient.
Electronic differential lock (EDL)
When the EDL detects wheelspin, it brakes
the spinning wheel and directs the power to
the other driven wheel. This function is active
up to approximately 100 km/h (62 mph).
To prevent the disc brake of the braked wheel
from overheating, the EDL cuts out automati-
cally if subjected to excessive loads. The ve-
hicle can still be driven. The EDL will switch on
again automatically when the brake has
cooled down. Tractor-trailer sway mitigation*
If the vehicl
e is pulling a trailer, it will control
the following: tractor-trailers tend to sway.
When the swaying of the trailer is felt by the
vehicle and detected by the ESC, it will auto-
matically brake the towing vehicle within the
limits of the system and mitigate the sway.
Tractor-trailer sway mitigation is not available
in all countries ››› page 303
.
Electronic engine torque management
(XDS)
When taking a curve, the driveshaft differen-
tial 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) re-
ceives less drive torque than the inner wheel.
This may mean that in certain situations the
torque delivered to the inner wheel is too
high, causing the wheels to spin. On the other
hand, the outer wheel is receiving a lower
drive torque than it could transmit. This can
cause a loss of grip on the drive axle, in this
case the front axle, which results in under-
steer or “lengthening” of the trajectory.
The XDS 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 requested
trajectory is much more precise. »
