Safety Operating and safety warnings
WARNING
● The Re ar As

sist does not make it possible
to precisely calculate the distance from ob-
stacles (people, vehicles, etc.) and nor can it
overcome the system's own limits, hence us-
ing it may cause serious accidents and inju-
ries if used negligently or without due care.
The driver should be aware of his/her sur-
roundings at all times to ensure safe driving.
● The camera lens expands and distorts the
field of
vision and displays the objects on the
screen in a different, vague manner. The per-
ception of distances is also distorted by this
effect.
● Due to the screen resolution or insufficient
light condition
s, some items may be dis-
played in an unsatisfactory manner or not at
all. Take special care with thin posts, fences,
railings or trees that might not be displayed
on screen and could damage the vehicle.
● The rear assist has blind spots where it is
not pos
sible to represent people or objects
(small children, animals and certain objects
cannot be detected in its field of vision). Mon-
itor the vehicle's surrounding area at all
times.
● Keep the camera lens clean, free of ice and
snow
, and do not cover it.
● The system is not a replacement for driver
awar
eness. Supervise the parking operation
at all times, as well as the vehicle's surround-
ing area. Adapt your speed and driving style at all times to suit visibility, weather, road
and traffic
c

onditions.
● Do not be distracted from the traffic by
looking at
the screen.
● The images on the rear assist screen are
only tw
o-dimensional. Due to a lack of spatial
depth, protruding parts or holes in the road,
for example, are more difficult to detect or
may not be seen at all.
● Vehicle load modifies the representation of
the orientation lines
displayed. The width
represented by the lines diminishes with ve-
hicle load. Pay special attention to the vehi-
cle's surroundings when the inside of the ve-
hicle of the luggage compartment is carrying
a heavy load.
● In the following situations, the objects or
other vehic
les shown in the navigation sys-
tem display appear to be further away or
closer than they really are: Pay special atten-
tion:
– On moving from a horizontal plane to a
slope.
– On moving from a slope to a horizontal
plane.
– If the vehicle is heavily loaded at the
rear.
– When the vehicle approaches objects
that are not on the ground surface or are
jutting out from it. These objects may al-
so be outside the camera's angle of vi-
sion when reversing. » 243

● Reverse slowly, and turn the steering wheel
so that the s

● Guide the vehicle into the parking space so
that the s
ide orientation lines run parallel to
it. 1

Advice
– If
y
ou wish to fit the vehicle with rims or
tyres different to those installed in manu-
facture, it is advisable to consult a SEAT Of- ficial Service before purchasing them.
The tyres and wheel rims are an essential
part of the vehicle's design. The tyres and
rims approved by SEAT are specially matched
to the characteristics of the vehicle and make
a major contribution to good roadholding
and safe handling ››› .
The s iz
e

s of the rims and tyres approved for
your vehicle are listed in the vehicle docu-
mentation (e.g. EC Certificate of Conformity or
COC document 1)
). The vehicle documentation
varies depending on the country of resi-
dence.
A knowledge of tyre designations makes it
easier to choose the correct tyres. The follow-
ing wording can be read on the sides of the
tyre:
205/55 R16 91V
This contains the following information:
205Tyre width in mm
55Height/width ratio in %
RTyre construction: Radial
16Rim diameter in inches
91Load rating code
VSpeed index The manufacturing date is also indicated on
the ty
r

e sidewall (possibly only on the outer
part):
DOT... 2216...
it means, for example, that the tyre was man-
ufactured in the 22nd week of 2016.
But note that with some types of tyre, the ac-
tual tyre size can differ from the nominal size
marked on the tyre (for instance 205/55 R 16
91 W), and there may be significant differen-
ces in the contours of the tyres, even though
the tyres are marked with the same nominal
size designation. When replacing the tyres,
it is therefore important to make sure that
the actual size of the new tyres does not ex-
ceed the dimensions of the factory-approved
makes of tyre.
Failure to observe this requirement can af-
fect the clearance needed for the tyres. If the
tyres rub against the bodywork, in certain
circumstances the tyres, running gear or
bodywork and pipes may be damaged, and
vehicle safety could be severely impaired
››› .
If
y

ou use tyres that are approved by SEAT
you can be sure that the actual tyre dimen- sions will be correct for your vehicle. If you
decide to fit

a different type of tyre, you must
obtain the appropriate manufacturer's certif-
icate from the tyre retailer to confirm that
the tyres are suitable for your vehicle. Keep
this certificate in a safe place.
Your SEAT Official Service will be able to ad-
vise you on which tyres may be fitted to your
vehicle.
It is best to have all servicing of wheels and
tyres performed by a specialised workshop.
They are familiar with the procedure and
have the necessary special tools and spare
parts as well as the proper facilities for dis-
posing of the old tyres respecting the envi-
ronment. WARNING
● It i s

very important to ensure that the tyres
you have chosen have adequate clearance.
When selecting replacement tyres, do not re-
ly entirely on the nominal tyre size marked on
the tyre, since the effective tyre size can dif-
fer significantly depending on the manufac-
turer. Inadequate tyre clearance can result in
damage to the tyres or the vehicle, causing a
serious safety risk. Risk of accident! It may
also invalidate the vehicle's registration for
use on public roads. 1)

Extraction of the spare wheel in vehi-
c l
e
s with SEAT SOUND 10 speakers
(with subwoofer)* Fig. 256
In the luggage compartment: re-
mo v
e the s

ubwoofer. To remove the spare wheel, you must first re-
mo
v
e the

subwoofer.
– Disassemble the subwoofer's
floor panel
(carpet) as follows:
– LEON/LEON SC model: first, p
ull the carpet
in the direction of the backrest and then
pull it upwards to remove it. LEON ST mod-
el: lift and secure the floor storage com-
partment as explained in ››› page 170.
– Disconnect the subwoofer’s
speaker cable
››› Fig. 256 1 . –
Turn the sec urin

g wheel anti-clockwise 2 .
– Remove the s ub
woofer
speaker and the
spare wheel.
– When re-mounting the spare tyre, place the
subwoofer

on the base of the wheel rim
with care. When doing so, the tip of the
“FRONT” arrow on the subwoofer should
point forward.
– Reconnect the speaker cable and firmly ro-
tate the sec

uring wheel clockwise so that
the subwoofer system and wheel are firmly
in place.
Winter service Winter ty
res –
Winter tyres must be fitted on al
l
four
wheels.
– Only use winter tyres that are approved for
your v

ehicle.
– Please note that the maximum permissible
speed for w

inter tyres may be lower than
for summer tyres.
– Also note that winter tyres are no longer ef-
fective when the

tread is worn down. –
After fittin
g the wheels you must always
check the tyre pressures. When doing so,
take into account the correct tyre pressures
listed on the rear of the front left door
frame ››› page 280.
In winter road conditions winter tyres will
considerably improve vehicle handling. The
design of summer tyres (width, rubber com-
pound, tread pattern) gives less grip on ice
and snow. This applies particularly to vehi-
cles equipped with wide section tyres or with
high speed tyres (code letters H, V or Y on
the sidewall).
Only use winter tyres of the correct type ap-
proved for your vehicle. The sizes of these
tyres are specified in the vehicle's docu-
ments (e.g. EC Certificate of Conformity or
COC 1)
). The vehicle documentation varies de-
pending on the country of residence. See al-
so ››› page 281.
Winter tyres lose a great deal of their proper-
ties when the tread is worn down to a depth
of 4 mm.
The performance of winter tyres is also se-
verely impaired by ageing, even if the tread is
still much deeper than 4 mm.
Winter tyres are subject to the following max-
imum speed limits according to speed rating
code letter: ››› »
