Transport and practical equipment
Variable floor in the tilted position
When the v
ari
able floor is tilted you can ac-
cess the spare wheel/anti-puncture kit area.
● Lift the variable floor using handle
›››
Fig. 180 1 and pull it back until the front
of the floor h
a
s fully passed the tilted
grooves ››› Fig. 181 3 .
● Run the floor through these grooves with
the help of h
andl

e 1 as the rear seat back-
r e
s
t and until the floor is resting in the
grooves. WARNING
During a sudden driving or braking manoeu-
vre, or in the ev ent

of an accident, objects
could be flung though the interior and cause
serious or fatal injuries.
● Always secure objects, even when the lug-
gage c
ompartment floor is properly lifted.
● Only objects that do not protrude more
than 2/3 the height of
the floor may be car-
ried between the rear seat and the raised lug-
gage compartment floor.
● Only objects that do not weigh than ap-
prox
imately 7.5 kg may be carried between
the rear seat and the raised luggage compart-
ment floor. CAUTION
● The max imum w

eight that can be loaded on
the luggage compartment variable floor in
the top position is 150 kg. ●
Do not l et

the luggage compartment floor
fall when closing it. Always carefully guide it
downwards in a controlled manner. Other-
wise, the lining and the floor of the luggage
compartment could be damaged. Note
SEAT recommends the use of straps to secure
o b j

ects to retaining rings. Roof carrier
Intr oduction The vehicle roof has been designed to opti-
mi
se aer
ody

namics. For this reason, cross
bars or conventional roof carrier systems can-
not be secured to the roof water drains.
As the roof water drains are integrated in the
roof to reduce air resistance, only SEAT-ap-
proved cross bars and roof carrier systems
can be used.
Cases in which cross bars and the roof carri-
er system should be disassembled.
● When they are not used.
● When the vehicle is washed in a car wash.
● When the vehicle height exceeds the maxi-
mum height, for e x

ample, in some garages. WARNING
When heavy or bulky loads are transported
on the roof c

arrier system, car driving per-
formance is affected, as the centre of gravity
shifts and there is greater wind resistance.
● Always secure the load properly using belts
or retainin
g straps that are suitable and in a
good condition.
● Bulky, heavy, long or flat loads have a neg-
ative effect
on aerodynamics, the centre of
gravity and driving performance.
● Avoid sudden braking and manoeuvres.
● Adapt your speed and driving style at all
times t
o suit visibility, weather, road and traf-
fic conditions. CAUTION
● Remo v

e the cross bars and the roof carrier
system before entering a car wash.
● Vehicle height is increased by the installa-
tion of cr
oss bars or a roof carrier system and
the load secured on them. For this purpose,
check that your vehicle's height does not sur-
pass the headspace limit, for example, for un-
derpasses or for entering garage doors.
● Cross bars, a roof carrier system and the
load sec
ured on them should not interfere
with the roof aerial or hamper the path of the
panoramic sun roof ››› page 126 and the rear
lid.
● On opening the rear lid make sure that it
does not
knock into the roof load. » 157

Note
Always read the assembly instructions that
come w ith the c
rossbars and the roof carrier
system carefully and keep them in the vehi-
cle. Loading the roof carrier system
The load can only be secured if the crossbars
and the roof
c

arrier system are properly in-
stalled ››› .
Max imum authori

sed roof load
The maximum permissible roof load is 75 kg.
This figure comes from the combined weight
of the roof carrier, the cross bars and the load
itself on the roof ››› .
A lw
a

ys check the weight of the roof carrier
system, the cross bars and the weight of the
load to be transported and weigh them if
necessary. Never exceed the maximum au-
thorised roof load.
If you are using cross bars and a roof carrier
with a lower weight rating, you will not be
able to carry the maximum authorised roof
load. In this case, do not exceed the maxi-
mum weight limit for the roof carrier which is
listed in the fitting instructions. Distributing a load
Distrib

ute loads uniformly and secure them
correctly ››› .
Chec k
att

achments
Once the cross bars and roof carrier system
have been installed, check the bolted con-
nections and attachments after a short jour-
ney and subsequently with a certain frequen-
cy. WARNING
Exceeding the maximum authorised roof load
can r e

sult in accidents and considerable vehi-
cle damage.
● Never exceed the maximum authorised
load on the r
oof and on the axles or the vehi-
cle's maximum authorised weight.
● Never exceed the load capacity of the cross
bars
and the roof carrier system, even if the
maximum authorised roof load has not been
reached.
● Secure heavy items as far forward as possi-
ble and di
stribute the vehicle load uniformly. WARNING
If the load is loose or not secured, it could fall
from the r oof

carrier system or cause acci-
dents and injuries.
● Always use belts or retaining straps that
are suit
able and in a good condition.
● Secure the load properly. Air conditioning

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 228.
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 figures for your specific
model, which may be lower than these fig-
ures for the towing bracket, are given in the
vehicle documentation or in ››› chapter Tech-
nical Data .
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
Set tyre pressure to the maximum permissi-
ble pressure shown on the sticker on the in-
side of the fuel tank flap. 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 226.
Trailer rear lights
The trailer's rear lights should comply with
the statutory safety regulations ››› page 226. 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. 225

is used to hook
up the trailer's retainer cable.
On hooking it up to the safety lug, the retain-
er cable should have slack in all the trailer
positions with respect to the vehicle (sharp
bends, reverse gear, etc.).
Headlights
The front part of the vehicle may be raised
when the trailer is connected and the light
may dazzle the rest of the traffic.
Adapt the height of the headlights using the
headlight range rotary adjuster 1)
. WARNING
● 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 55.
● 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. 1)
This does not apply for vehicles with bi-xenon
hea dlights.
