Exterior mirrors
Chec k
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 240.
Trailer rear lights
The trailer's rear lights should comply with
the statutory safety regulations ››› page 240. 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. Hitching and connecting the trailer

The v
ehic

le is fitted with a 13-pole power
socket for the electrical connection between
the trailer and the vehicle. If the system de-
tects that a trailer has been connected elec-
trically, the electrical equipment on the trailer
will receive voltage through this connection.
Pin 9 has a permanent live. This powers, for
example, the trailer's interior lighting. Pin 10
is only powered when the engine is running.
The charge wire (pin 10) charges, for exam-
ple, a caravan battery.
Pin 9 and 10 should not be connected to
each other to avoid discharging or damaging
the vehicle's battery.
The earth wires, pin 3, pin 11 and pin 13,
should never be connected to each other to
avoid overloading the electrical system.
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.

● Never u se the s

afety lug to tow!
● Adjust your speed to suit the road and traf-
fic condition
s.
● All work on the electrical system must be
carried out on
ly by specialised workshops.
● Never connect the trailer's electric system
to the electric
al connections of the rear lights
or any other power sources.
● After hooking up the trailer and connecting
the socket, c
heck that all the trailer's rear
lights are working properly. Note
● If ther e i

s any fault in the trailer's lighting,
check the fuses in the instrument panel fuse
box ›››
 page 54.
● The contact between the retainer cable and
the safety
lug may give rise to mechanical
wear in the lug's surface protection. This
wear will not prevent the safety lug from op-
erating properly or cause any fault and is ex-
cluded from the warranty.
● When connecting and disconnecting the
trail
er, the towing vehicle's handbrake
should be applied. Anti-theft alarm system
When the vehicle is locked, the alarm is trig-
g
er
ed when the el

ectrical connection be-
tween vehicle and trailer is interrupted.
Always turn off the anti-theft alarm system
before connecting or disconnecting a trailer
››› page 124.
Conditions for the integration of a trailer in
the anti-theft alarm system.
● The vehicle is factory-equipped with an an-
ti-theft al
arm system and a towing bracket
device. ●
The trail
er is connected electrically to the
towing vehicle by the trailer connector.
● The electrical system of the vehicle and the
trail
er are prepared for operation.
● The vehicle is locked with the ignition key
and the anti-theft al
arm system is activated. CAUTION
For technical reasons, trailers fitted with rear
LED lights ar

e not integrated in the anti-theft
alarm system. Driving tips
Driving with a trailer always requires extra

eight distribution
The weight distribution of a loaded trailer
with an unladen vehicle is very unfavourable.
However, if this cannot be avoided, drive ex-
tra slowly to allow for the unbalanced weight
distribution.
Speed
The stability of the vehicle and trailer is re-
duced with increasing speed. For this reason,
it is advisable not to drive at the maximum 1)
This does not apply for vehicles with bi-xenon
hea dlights.

permissible speed in an unfavourable road,
w e
ather or w
ind conditions. This applies es-
pecially when driving downhill.
You should always reduce speed immediately
if the trailer shows the slightest sign of snak-
ing. Never try to stop the “snaking” by in-
creasing speed.
Always brake in due course. If the trailer has
an overrun brake, apply the brakes gently at
first and then, firmly. This will prevent the
jerking that can be caused by locking of trail-
er wheels. Select a low gear in due course
before going down a steep downhill. This en-
ables you to use the engine braking to slow
down the vehicle.
Reheating
At very high temperatures and during pro-
longed slopes, driving in a low gear and high
engine speed, always monitor the coolant
temperature gauge ››› page 109.

according to the instructions of the towing
bracket manufacturer. The attachment points for the towing bracket
A are on the lower part of the vehicle.
The di s

●
Driving with a trailer involves an extra effort

towing bracket, please contact a Technical
Service to check whether your cooling system
needs modification.
● The legal requirements in your country
must
be observed (e.g. the fitting of a sepa-
rate control lamp).
● Certain vehicle components, e.g. the rear

● SEA T r

ecommends that the towing hooks
be fitted at a specialised workshop. Consult
your SEAT dealer in case additional modifica-

● Due to the specific design of the exhaust,
the fitting of a c
onventional towing hook is
not recommended for some sportier versions.
Please consult your Technical Service. 244

Electro-mechanical power steering adapts
electronically to the speed of the car, torque

If the power steering should fail at any time
or the engine is switched off (for instance
when being towed), the car can still be
steered. However, more effort than normal
will be required to turn the steering wheel.

Drawbar loads
The maximum permitt ed dr
a
wbar load on the
ball joint of the towing bracket must not ex-
ceed 80 kg.
In the interest of road safety, we recommend
that you always tow approaching the maxi-
mum drawbar load. The response of the trail-
er on the road will be poor, if the drawbar
load is too small.
If the maximum permissible drawbar load
cannot be met (e.g. with small, empty and
light-weight single axle trailers or tandem
axle trailers with a wheelbase of less than 1
metre), a minimum of 4% of the actual trailer
weight is legally required for the drawbar
load. WARNING
● For s af

ety reasons, you should not drive at
speeds above 80 km/h (50 mph) when towing
a trailer. This also applies in countries where
higher speeds are permitted.
● Never exceed the maximum trailer weights
or the drawb
ar load. If the permissible axle
load or the permissible total weight is excee-
ded, the driving characteristics of the vehicle
may change, leading to accidents, injuries
and damage to the vehicle. Wheels

e pressure, snow chains, wheel
bolts Tyre pressures
The stic
k

er with the tyre pressure values can
be found on the rear of the front left door
frame. The tyre pressure values given there
are for cold tyres. The slightly raised pres-
sures of warm tyres must not be reduced.
››› The pressure for win
t
er
tyres is 0.2 bar
(2.9 psi / 20 kPa) higher than that of summer
tyres.
Snow chains
Snow chains may be fitted only to the front
wheels, and only for the following tyres:
195/65 R15Chains with links of maximum 15 mm
205/55 R16Chains with links of maximum 15 mm
205/50 R17Chains with links of maximum 15 mm
225/45 R17Chains with links of maximum 9 mm
225/40 R18Chains with links of maximum 9 mm
225/35 R19Chains with links of maximum 7 mm
205/55 R17Snow chains are not permitted
225/45 R18Snow chains are not permitted Wheel bolts
Af
t
er the wheel

s have been changed, the
tightening torque of the wheel bolts should
be checked as soon as possible with a torque
wrench ››› . The tightening torque for steel
and al lo
y

wheels is 120 Nm. WARNING
● Check the ty

re pressure at least once per
month. Checking the tyre pressure is very im-
portant. If the tyre pressure is too high or too
low, there is an increased danger of accidents
- particularly at high speeds.
● If the tightening torque of the wheel bolts
is t
oo low, they could loosen while the vehi-
cle is in motion. Risk of accident! If the tight-
ening torque is too high, the wheel bolts and
threads can be damaged. Note
We recommend that you ask your Technical
Serv ic

e for information about appropriate
wheel, tyre and snow chain size. 283
