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

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

e warning will
sound.
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

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.

Towing bracket device*
This powers, for example, the trailer's interior
lighting. El ectrical de
vices such as a fridge in
a caravan only receive electrical power if the
engine is running (through pin 10).
To avoid overloading the electrical system,
you cannot connect the ground wires of pin
3 , pin 11 or pin 13 to each other.
If the trailer has a 7-contact connector, you
will need to use an adapter cable. In this case
the function corresponding to pin 10 will not
be available.
Tow cable
The tow rope must always be securely fixed
to the towing vehicle and loose enough so
that the vehicle can handle turns smoothly.
However, make sure that the cable does not
rub on the ground while driving.
Trailer tail lights
Always check the trailer's rear lights to ensure
they are working correctly and that they
comply with the relevant safety regulations. If
you connect the trailer to the factory-moun-
ted system, when you turn on the rear fog
lamp, the fog lamp of the towing vehicle will
turn off to turn on the trailer fog lamp.
Include in the anti-theft alarm
The trailer is included in the anti-theft system
if the following conditions are met:

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.
Conservation of the high-
volt
age battery
Conservation instructions  V

or: hybrid vehicles
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.
Please also observe the applicable SEAT
warranty conditions for the high-voltage bat-
tery.
Conservation instructions
SEAT recommends the following conserva-
tion instructions:

do not st ar
t the engine. This could result in
damage to the engine and catalytic con-
verter. Contact a specialised workshop. For the sake of the environment
The oil level must never be above zone

A . Otherwise oil can be drawn
in thr ough the cr
ankcase breather and leak
into the atmosphere via the exhaust sys-
tem. Note
Before a long trip, we recommend finding
an engine oil that conf orms t

o the corre-
sponding VW specifications and recom-
mend keeping it in the vehicle. This way, the
correct engine oil will always be available
for a top-up if needed. Engine oil change
We recommend that you have the engine oil
changed by a T
echnical Service

. WARNING
Only change the engine oil yourself if you
hav e the specialist kno

wledge required!

Wheels
New wheels and tyres It is best to have all wheels and tyres serviced
by a specialised w
orkshop
. There they have
the required knowledge, the special tools and
the corresponding spare parts.
