The essentials
CAUTION
● Remo v
e the snow chains to drive on roads
without snow. Otherwise they will impair
vehicle handling, damage the tyres and wear
out very quickly.
● Wheel rims may be damaged or scratched if
the chain
s come into direct contact with
them. SEAT recommends the use of covered
snow chains. Note
Snow chains are available in different sizes
acc or

ding to the vehicle type. Emergency towing of the vehi-

Screw the front towline anchorage into the
screw connection ››› Fig. 58 and tighten it
with the wheel brace.
Tow rope or tow bar
When towing, the tow bar is the safest and
vehicle friendly way. You should only use a
tow rope if you do not have a tow bar. A tow rope should be slightly elastic to avoid
damag

e to both vehicles. It is advisable to
use a tow rope made of synthetic fibre or sim-
ilarly elastic material.
● Only secure the tow rope or tow bar to the
towline anc
horage or specially designed fit-
ting.
Notes for the driver of the towed vehicle
● Keep the ignition running to prevent the
steerin
g wheel from locking and also to allow
the use of the turn signals, horn, windscreen
wipers and washers.
● As the power assisted steering does not
work if
the engine is not running, you will
need more strength to steer than normally.
● The brake must be depressed much harder
as the br
ake servo does not operate. Avoid
hitting the towing vehicle.
● Note the instructions and information con-
tained in the Ins
truction Manual for the vehi-
cle to be towed.
Notes for the driver of the towing vehicle
● Accelerate gently and carefully. Avoid sud-
den manoeuvr
es.
● Brake well in advance than usual and brake
gently.
● Not

e the instructions and information con-
tained in the In s

truction Manual for the vehi-
cle to be towed. » 41

Safety
●
Sit a s
far away as possible from the steer-
ing wheel and the dash panel.
● Keep your back straight and resting com-
plet
ely against the seat backrest and the
front seats correctly adjusted. Never place
any part of your body in the area of the airbag
or very close to it.
● If passengers on the rear seats are not sit-
ting in an upright po
sition, the risk of severe
injury due to incorrect positioning of the belt
web increases. WARNING
Incorrect seat adjustment may lead to acci-
dents and sev

ere injuries.
● Only adjust the seats when the vehicle is
station
ary, as the seats could move unex-
pectedly while the vehicle is in motion and
you could lose control of the vehicle. Further-
more, an incorrect position is adopted when
adjusting the seat.
● Only adjust the height, seat backrest and
forw
ards or backwards position of the seat
when there is nobody in the seat adjustment
area.
● There must be no objects blocking the front
seat a
djustment area. Adjusting the rear head restraints
Fig. 66
Adjusting the rear head restraints All seats are equipped with a head restraint.
The fr
ont
se

at head restraints are integrated
in the backrests and adjusting them is not
possible.
Adjusting height
● Push the head restraint up or down in the
direction of the arr
ow with the button press-
ed ››› Fig. 66 1
› ›
› .
● The head restraint must engage securely in
po s
ition.
C

orrect adjustment of head restraints
Adjust the head restraint so that its upper
edge is at the same level as the top of your
head, or as close as possible to the same lev-
el as the top of your head and under no cir-
cumstances below eye level. Keep the back of your neck as close as possible to the head
res

traint.
Adjusting the head restraint for short people
Set the head restraint in the first anchorage
position, even if your head is below its upper
edge. When the head restraint is at its low-
est, it is possible that a small gap remains
between it and the seat backrest.
Adjusting the head restraint for tall people
Raise the head restraint completely. WARNING
Travelling with the head restraints removed
or improperly a

djusted increases the risk of
severe or fatal injuries in the event of acci-
dents and sudden braking or manoeuvres.
● Always fit and adjust the head restraint
properly whenev
er a person is occupying a
seat.
● All vehicle occupants must correctly adjust
the head r
estraint according to their height to
reduce the risk of back injuries in the event of
an accident. The upper edge of the head re-
straint must be as close as possible to the
same level as the top of your head and under
no circumstances below eye level. Keep the
back of your neck as close as possible to the
head restraint.
● Never adjust the head restraint while the
vehicl
e is in motion.50

Seat belts
Pedal area P ed
a
ls Do not allow floor mats or other objects to
ob
s

truct the free passage of the pedals.
Floor mats should leave the pedal area free
and unobstructed and be correctly secured in
the footwell zone.
In the event of failure of a brake circuit, the
brake pedal must be pressed harder than
normal to brake the vehicle. WARNING
Objects falling into the driver's footwell could
prev ent

use of the pedals. This could lead the
driver to lose control of the vehicle, increas-
ing the risk of a serious accident.
● Make sure the pedals can be used at all
times, with no o
bjects rolling underneath
them.
● Always secure the mat in the footwell.
● Never place other mats or rugs on top of
the original
mat supplied by the factory.
● Ensure that no objects can fall into the driv-
er's footw
ell while the vehicle is in motion. CAUTION
The pedals must always have free and unob-
struct ed p

assage to the floor. For example, in
case of a fault in the brake circuit, the brake pedal will need to be pressed further to stop
the v
ehic

le. To press the brake pedal down
further will require more force than usual. Seat belts
Wh y
w
ear a seat belt?
Introduction Check the condition of all the seat belts at
re
gu

lar intervals. If you notice that the belt
webbing, fittings, retractor mechanism or
buckle of any of the belts is damaged, the
belt must be replaced immediately by a spe-
cialised workshop ››› . The specialised
w ork
shop mu

st use the appropriate spare
parts corresponding to the vehicle, the
equipment and the model year. SEAT recom-
mends taking your car in for technical serv-
ice. WARNING
Unbuckled or badly buckled seat belts in-
cr e

ase the risk of severe or even fatal inju-
ries. The seat belt cannot offer its full protec-
tion if it is not fastened and used correctly.
● Seat belts are the most effective way of re-
ducing the ri
sk of sustaining severe or fatal
injuries in the event of an accident. Seat belts
must be correctly fastened when the vehicle
is in motion to protect the driver and all vehi-
cle occupants.
● Before each trip, every occupant in the ve-
hicle oc
cupants must sit properly, correctly
fasten the seat belt belonging to his or her
seat and keep it fastened throughout the trip. » 51

● When travelling, children must be secured
in the vehic
le with a child restraint system
suitable for their weight and height and with
the seat belts correctly fastened
››› page 63.
● Instruct your passengers to fasten their
seat belt
s properly before driving off.
● Insert the latch plate into the buckle for the
appropri
ate seat and ensure it is engaged.
Using the latch plate in the buckle of another
seat will not protect you properly and may
cause severe injuries.
● Do not allow liquids or foreign bodies to en-
ter the buc
kle fastenings. This could damage
the buckles and seat belts.
● Never unbuckle your seat belt when the ve-
hicle i
s moving.
● Never allow more than one passenger to
share the s
ame seat belt.
● Never hold children or babies on your lap
sharing the s
ame seat belt.
● Loose, bulky clothing (such as a jacket) im-
pairs
the proper fit and function of the seat
belt. WARNING
It is extremely dangerous to drive using dam-
aged se at

belts and could result in serious in-
jury or loss of life. ●

amaging the seat belt by jamming it
in the door or the seat mechanism.
● If the fabric or other parts of the seat belt
are dam
aged, the seat belts could break in
the event of an accident or sudden braking.
● Always have damaged seatbelts replaced
immediately
by seat belts approved for the
vehicle in question by SEAT. Seat belts which
have been worn in an accident and stretched
must be replaced by a specialised workshop.
Renewal may be necessary even if there is no
apparent damage. The belt anchorage should
also be checked.
● Never attempt to repair, modify or remove a
seat belt
yourself. All repairs to seat belts, re-
tractors and buckles must be carried out by a
specialised workshop. Warning lamp

Correct seat belt position
Seat belts offer their maximum protection in
the event of an accident and reduce the risk
of sustaining severe or fatal injuries only
when they are properly positioned. Further-
more, if the webbing is correctly positioned,
the seat belt will hold the vehicle occupants
in the optimum position to ensure the airbag
provides the maximum protection. The seat
belt must therefore always be worn and the
webbing correctly positioned.
Incorrectly worn seat belts can cause severe
or even fatal injuries ››› page 47, Correct po-
sition of the vehicle occupants .
● The shoulder part of the seat belt must lie
on the centre of
the shoulder, never across
the neck or the arm, under the arm or behind
the shoulder. ●
The lap par
t of the seat belt must lie across
the pelvis, never across the stomach.
● The seat belt must lie flat and fit comforta-
bly. P
ull the belt tight if necessary to take up
any slack.
In the case of pregnant women , the seat belt
must lie evenly across the chest and as low
as possible over the pelvis, never across the
stomach and must be worn properly at all
times during the pregnancy ››› Fig. 73.
Adapting the position of the belt webbing to
your size
The seat belt can be adapted using the fol-
lowing equipment:
● Front seat height adjustment. WARNING
An incorrectly worn seat belt web can cause
sever e or f

atal injuries in the event of an acci-
dent.
● The seat belt cannot offer its full protection
