cause the driving wheels to spin, which could
result in skidding. 232

Driver assistance systems
Traffic sign detection system* 1)
Intr oduction The traffic sign detection system records the
st
and
ard traffic signs in front of the vehicle
with a camera located on the base of the in-
terior mirror and provides information about
speed limits and overtaking prohibitions.
Within its limitations, the system also dis-
plays additional signals, such as time-specif-
ic prohibitions, signs for vehicles towing trail-
ers ›››
page 246 or limitations that only apply
in the event of rain. Even on journeys without
signs, the system may display any applicable
speed limits.
In Germany, on motorways and vehicle roads,
besides speed limits and overtaking provi-
sions the system also displays the end of
prohibition signs. The valid speed limit at the
time in other countries is always shown. WARNING
The technology in the traffic sign detection
sys t

em cannot change the limits imposed by
the laws of physics and only works within the
system's limits. Do not let the extra conven-
ience afforded by the traffic sign detection
system tempt you into taking any risks when
driving. The system is not a replacement for
driver awareness. ●
Adapt

your speed and driving style to suit
visibility, weather, road and traffic condi-
tions.
● Poor visibility, darkness, snow, rain and fog
may
lead to the system failing to display traf-
fic signs or not displaying them correctly.
● If the camera's field of vision is dirty, cov-
ered or dam
aged, system operation may be
impaired. WARNING
The driving recommendations and traffic indi-
c ation s

shown on the traffic sign detection
system may differ from the actual current
traffic situation.
● The system may not detect or correctly
show al
l the traffic signs.
● Traffic signs and traffic regulations have
priority ov
er the recommendations and dis-
plays provided by the system. Note
In order not to compromise the system's op-
eration, p l

ease take the following points into
account:
● Regularly clean the area of vision of the
camera and k
eep it in a clean state, without
snow or ice. ●
Do not c o

ver the field of vision of the cam-
era.
● Always replace damaged or worn blades
when required t
o avoid lines on the camera's
field of vision.
● Check that the windscreen is not damaged
in the area of
the camera's field of vision. Note
● The u se of out

dated maps on the naviga-
tion system may cause the system to show
traffic signs incorrectly.
● In the waypoints mode of the navigation
syst
em, the traffic sign detection system is
only partly available. 1)

tional rain sign.
If the windscreen wiper is
working while you are driving, the signal
with the additional rain sign will be
shown first, on the left, as it is the one
that is applicable at the time.
A sign valid only with restrictions, e.g.
No overtaking at certain times, will be
displayed third ››› Fig. 222 C.
Speed warning
If the system detects that the permitted
speed is exceeded, it may warn the driver
with a “gong” and visually with a message

For trailer mode, the display of speed limits
applicable to the type of trailer or to the legal
provisions can be adjusted. The speed is ad-
justed in steps of 10 km/h (5 mph) within a
range of between 60 km/h (40 mph) and
130 km/h (80 mph). If it is adjusted to a
speed greater than that which is permitted in
the country in question for driving with a
trailer, the system automatically displays the
usual speed limits, e.g. in Germany 80 km/h
(50 mph).
If the speed warning for the trailer is deacti-
vated, the system displays the speed limits
as if there were no trailer hitched. Limited operation

Towing bracket device
Trailer towing Wh at
do
you need to bear in mind
when towing a trailer? Your vehicle may be used to tow a trailer
when fitted w
ith the c

orrect equipment.
If you wish to retrofit a towing bracket, con-
sult ››› page 254.
Connectors
Your vehicle is fitted with a 13-pin connector
for the electrical connection between the
trailer and the vehicle.
If the trailer has a 7-pin plug you will need to
use an adapter cable. It is available at any
Technical Service.
Trailer weight/drawbar load
Never exceed the authorised trailer weight. If
you do not load the trailer up to the maxi-
mum 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. With increasing altitude the engine
power and therefore the vehicle climbing
ability are impaired because of the reduced
air density. The maximum trailer weight has
to be reduced accordingly. The weight of the
vehicle and trailer combination must be re- duced by 10% for every further 1000 m (or
par
t

thereof). The gross combination weight
is the actual weight of the laden vehicle plus
the actual weight of the laden trailer. When
possible, operate the trailer with the maxi-
mum permitted drawbar load on the ball joint
of the towing bracket, but do not exceed the
specified limit.
The figures for trailer weights and drawbar
loads that are given on the data plate of the
towing bracket are for certification purposes
only. The correct towing bracket figures for
your specific model, which may be lower than
these figures, are given in the vehicle docu-
mentation or on ››› page 289, Technical
specifications.
Distributing the load
Distribute loads in the trailer so that heavy
objects are as near to the axle as possible.
Loads carried in the trailer must be secured
to prevent them moving.
Tyre pressure
The maximum permissible tyre pressure val-
ues are shown on the sticker on the back of
the left front door frame. Set the tyre pres-
sure of the trailer tyres in accordance with the
trailer manufacturer's recommendations. Exterior mirrors
Check whether
you can see enough of the
road behind the trailer with the standard rear
vision mirrors. If this is not the case, you
should have additional exterior mirrors fitted.
Both exterior mirrors should be mounted on
hinged extension brackets. Adjust the mirrors
to give sufficient vision to the rear.
Tow rope
Always use a cable between the vehicle and
the trailer ››› page 252.
Trailer rear lights
The trailer's rear lights should comply with
the statutory safety regulations ››› page 252. WARNING
Never transport people in a trailer. This could
re s

ult in fatal accidents. Note
● To w

ing a trailer places additional demands
on the vehicle. We recommend additional
services between the normal inspection inter-
vals if the vehicle is used frequently for tow-
ing a trailer.
● Find out whether special regulations apply
to to
wing a trailer in your country. 251

n
leaded petrol
We recommend you use super 95 octane pet-
rol. If this is not available: normal 91 octane
petrol, with a slight decrease in power.
Super unleaded petrol with a minimum of 95
octanes
You should use super petrol with a minimum
of 95 octanes.
If super is not available, in an emergency you
may refuel with normal 91 octane petrol. In
this case only use moderate engine speeds
and a light throttle. Refuel with super as soon
as possible.
Super unleaded 98 octane or super 95 oc-
tane unleaded petrol
We recommend you use super plus 98 octane
petrol. If this is not available: super 95 oc-
tane petrol, with a slight decrease in power.
If super is not available, in an emergency you
may refuel with normal 91 octane petrol. In
this case only use moderate engine speeds
and a light throttle. Refuel with super as soon
as possible.
Petrol additives
The quality of the fuel influences the behav-
iour, power and service life of the engine.
This is why the petrol you use should carry
suitable additives already included by the petrol industry, free of metals. These addi-
tives
will help to prevent corrosion, keep the
fuel system clean and prevent deposits from
building up in the engine.
If good-quality petrol with metal-free addi-
tives is not available or engine problems
arise, the necessary additives must be added
when refuelling ››› .
Not al
l

petrol additives have been shown to
be effective. The use of unsuitable petrol ad-
ditives may cause significant damage to the
engine and the catalytic converter. Metal ad-
ditives should never be used. Metal additives
may also be contained in petrol additives for
improving anti-detonation ratings or octane
ratings ››› .
S EA
T r

ecommends “genuine Volkswagen
Group Fuel Additives for petrol engines”.
These additives can be bought at SEAT deal-
ers, where information on how to use them
can also be obtained. CAUTION
● Do not r ef

uel if the filler indicates that the
fuel contains metal. LRP ( lead replacement
petrol) fuels contain high concentrations of
metal additives. Using them may damage the
engine!
● Never refuel with fuels containing a large
proportion of
ethanol (for example, E50, E85).
This could damage the fuel system. ●
Jus t

filling one full tank of leaded fuel or
fuel containing other metal additives would
seriously impair the efficiency of the catalytic
converter.
● Only use fuel additives that have been ap-
prov
ed by SEAT. Octane boosting or anti-
knock additives may contain metal additives
that could seriously damage the engine or
the catalytic converter. These additives must not be used.
● High engine speed and full throttle can
damag
e the engine when using petrol with an
octane rating lower than the correct grade for
the engine. Note
● You m a

y use petrol with a high octane num-
ber than the one recommended for your en-
gine.
● In those countries where unleaded petrol is
not avai
lable, you may refuel with a fuel with
a low lead content. Diesel fuel
