Driving
To ensure that the drive system can be
s wit
ched on, even in very low outside temper-
atures, SEAT recommends parking the vehicle
in a place protected from the cold. Note
A click is heard when the drive system is
t urned on. This is compl

etely normal and
does not mean there is a problem. Starting the engine

Driving
The engine can only be started using a genu-
ine SEAT k ey with its corr
ect code.Note
A perfect operation of the vehicle is ensur-
ed if genuine SEAT k eys ar

e used.Emergency starting function

In the centre console: emergency
st art. If no valid key is detected inside the vehicle,
an emer
gency st

art-up will be required. The
relevant message will appear in the dash
panel display. This may happen when, for ex-
ample, the vehicle key battery is very low:

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:

Driving
Check tyre pressure
Al w
ays make sure the tyres are inflated to the
correct pressures ››› page 348
to save fuel. If
the pressure is below half bar, fuel consump-
tion may increase by 5%. Due to the greater
rolling resistance, under-inflation also increa-
ses tyre wear and impairs handling.
Do not use winter tyres all year round as
they increase fuel consumption by up to 10%.
Avoid carrying unnecessary loads
Given that every kilo of extra weight will in-
crease the fuel consumption, it is advisable
make sure that no unnecessary loads are be-
ing transported.
Since the luggage rack increases the aero-
dynamic drag 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*. Plug-in hybrid drive: brak
e early and evenly
to take advantage of energy recovery. Note

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:

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:

Driving
Towing bracket device*
T r
ailer mode
Introduction Take into account country-specific regula-
tions about driving with a tr
ail

er and the use
of a towing bracket.
The vehicle has been developed primarily for
carrying people, although it can also be used
to tow a trailer if fitted with the corresponding
technical equipment. This additional load has
an effect on the useful life, fuel consumption
and vehicle performance and in some cases
can reduce the service intervals.
Driving with a trailer requires more force from
the vehicle, and thus more concentration
from the driver.
In winter, winter tyres should be fitted on both
the vehicle and the trailer.
Maximum vertical load technically permit-
ted on the coupling device
The maximum technical permitted vertical
load of the trailer's towing bracket on the
hook of the tow-bar is 80 kg.
Vehicles with the Start-Stop system
If the vehicle has a factory-fitted towing
bracket or one that is retrofitted by SEAT, the Start-Stop system operates as normal. No
special char
act

eristics need to be taken into
account.
If the system does not recognise the trailer or
the trailer bracket has not been retrofitted by
SEAT, the Start-Stop system must be discon-
nected by pressing the corresponding button
in the lower part of the centre console before
driving with the trailer, and it should remain
off for the rest of the journey ››› .
V ehicl

es with driving profile selection
If you are going to be towing a trailer, the use
of the Eco driving profile is not recommen-
ded. You are advised to select another of the
available driving profiles before beginning to
drive with a trailer.
Trailer weight/drawbar load
Never exceed the authorised trailer weight. If
you do not load the trailer up to the maximum
permitted trailer weight, you can then climb
correspondingly steeper slopes.
The maximum trailer weights listed are only
applicable for altitudes up to 1000 m above
sea level. Since higher altitude decreases en-
gine performance and the ability to climb
slopes, the tow load decreases proportional-
ly. The weight of the vehicle and trailer com-
bination must be reduced by 10% for every
1000 m of altitude. When possible, operate
the trailer with the maximum authorised drawbar load on the ball joint of the to

wing
bracket, but do not exceed the specified lim-
it. WARNING
Never use the trailer to transport people,
since it w oul

d put their life in danger and is
also prohibited. WARNING
Undue use of the towing bracket may
cause injury and accidents.

Driving
Trailer brakes
If the tr ail
er has its own brake system, please
take the relevant legal requirements into ac-
count. Never connect the trailer's brake sys-
tem to the vehicle's brake system.
Tow cable
Always use a cable between the vehicle and
the trailer ››› page 300
.
Trailer tail lights
The trailer's rear lights should comply with
the statutory safety regulations ››› page 300
.
Never connect the trailer's rear lights directly
to the vehicle's electric system. If you are not
sure that the trailer's electrical connection is
correct, have it checked by a specialised
workshop. SEAT recommends visiting a SEAT
dealership for this.
Exterior mirrors
If you cannot see the area behind the trailer
with the exterior mirrors of the towing vehicle,
additional mirrors will have to be installed in
accordance with the regulations of the coun-
try in question. The exterior mirrors should be
adjusted before you start driving and must
provide a sufficient field of vision at the rear. WARNING
If the towing bracket is wrongly fitted or is
not the right one , the tr

ailer could become detached from the vehicle and cause seri-
ous injury.
CAUTION

Practical tips
Incorrect handling of the high-voltage
batt ery can cause serious injuries or
death. Maint
enance work on the high-
voltage battery must only be performed
by specialized personnel with the corre-
sponding qualifications and training. Nev-
er modify the high-voltage battery. When
the high-voltage battery is open, ensure it
does not come into contact with water or
other liquids. Liquids may cause short cir-
cuits, electrical shocks and burns.

Reliability and capacity of the high-volt-
age battery
Lithium ion batteries are subject to ageing
and wear and tear throughout their useful life
due to their physical and chemical charac-
teristics. Correct handling of the high-voltage
battery makes an essential contribution to
keeping it in a reliable state in the long term
and to achieving high battery capacity and
range. Therefore, it is extremely important to
respect the following conservation instruc-
tions for the high voltage battery. These 7 maintenance instructions are essential for
maint
aining the v

ehicle's value over time.
