››› .Important information about wheel bolts
The wheel
rims and bo

lts have been de-
signed to be fitted to factory options. If differ-
ent rims are fitted, the correct wheel bolts
with the right length and correctly shaped
bolt heads must be used. This ensures that
wheels are fitted securely and that the brake
system functions correctly.
In some circumstances, wheel bolts from the
same model vehicle should not be used.
Wheel bolt tightening torque
The prescribed tightening torque for wheel
bolts for steel and alloy wheels is 110 Nm.
Have the tightening torque of the wheel bolts
checked as soon as possible with a reliable
torque wrench.
If wheel bolts are rusty and it is difficult to
tighten them, the threads should be replaced
and cleaned before checking the tightening
torque.
Never grease or lubricate wheel bolts or the
wheel hub threads. Although they have been
tightened to the prescribed torque, they
could come loose while driving. WARNING
If the wheel bolts are not fitted correctly they
cou l

d be released while driving leading to
loss of vehicle control and serious damage. 38

The essentials
●
Only u
se wheel bolts which correspond to
the wheel rims in question.
● Never use different wheel bolts.
● The bolts and threads should be clean, free
of oil
and grease and easy to thread.
● To loosen and tighten the wheel bolts, al-
way
s use the wheel brace supplied with the
vehicle.
● Loosen the wheel bolts only about one turn
before r
aising the vehicle with the jack.
● Never grease or lubricate wheel bolts or the
wheel hub thre
ads. Although they have been
tightened to the prescribed torque, they
could come loose while driving.
● Never loosen the bolted joints of wheel
rims with bo
lted ring trims.
● If the wheel bolts are not tightened to the
correct
torque, they may come loose while
driving, and the bolts and rims may come
out. If the tightening torque is too high, the
wheel bolts and threads can be damaged. Raising the vehicle with the jack

The essentials
WARNING
If the vehicle is not correctly raised, it could
fa l
l off the jack causing serious injury. Please
observe the following rules to minimise the
risk of injury:
● You should only use a jack approved by
SEAT f
or your vehicle. Other jacks, even those
approved for other SEAT models, might slip
out of place.
● The ground should be firm and flat. If the
ground i
s sloped or soft then the vehicle
could slip and fall off the jack. If necessary,
support the jack on a wide solid base.
● If the ground is slippery, such as tiles,
plac
e a non-slip surface (a floor mat, for in-
stance) beneath the jack to avoid slipping.
● Only fit the jack at the prescribed jacking
points. The c
law of the jack should grip the
reinforcement nerve on the underbody
››› Fig. 56.
● You should never place a body limb such as
an arm or leg u
nder a raised vehicle that is
solely supported by the jack.
● If you have to work underneath the vehicle,
you mus
t use suitable stands additionally to
support the vehicle, there is a risk of acci-
dent!.
● Never raise the vehicle if it is tilting to one
side or the engine i
s running.
● Never start the engine when the vehicle is
raised.
The vehicle may come loose from the
jack due to the engine vibrations. Removing and fitting a wheel

● Using the hexagonal socket in the wheel
brace ›

›› Fig. 57, unscrew the slackened
wheel bolts and place them on a clean sur-
face.
● Take off the wheel.
How to u
se the spare wheel or temporary
spare wheel
Check the direction of rotation of the tyre
›››  page 208, Tyre code. ●
Place the s
pare wheel or temporary spare
wheel into position.
● Replace the wheel bolts and tighten slight
-
ly using the hexagonal socket on the end of
the wheel brace.
● To tighten the anti-theft locking wheel bolts
use the corr
esponding adaptor.
● Lower the car with the jack.
● Tighten all of the wheel bolts clockwise
›››
. Tighten the bolts in diagonal pairs (not
in a c ir
c
le).
● Put the caps, trim or full hubcap back on
›››
page 37. WARNING
If the wheel bolts are not treated suitably or
not tight ened t

o the correct torque then this
could lead to loss of vehicle control and to a
serious accident.
● All the wheel bolts and hub threads should
be cle
an and free of oil and grease. The wheel
bolts should be easily tightened to the cor-
rect torque.
● The hexagonal socket in the wheel brace
should be u
sed for turning wheel bolts only.
Do not use it to loosen or tighten the wheel
bolts. 40

The essentials
Tyres with compulsory direction of ro-
t ation A directional tread pattern can be identified
by
the arr
ows on the sidewall that point in
the direction of rotation. Always observe the
direction of rotation indicated when fitting
the wheel to guarantee optimum properties
of this type of tyres with regard to grip,
noises, wear and aquaplaning.
If it is absolutely necessary to fit the spare
tyre* against the direction of rotation, drive
with care as this means the tyre does not of-
fer optimum driving properties. This is of par-
ticular importance when the road surface is
wet.
To return to directional tread tires, replace
the punctured tyre as soon as possible and
restore the obligatory direction of rotation of
all tyres.
After the wheel change ●
Clean the vehicle tools, if necessary and
p ut
them a

way in the luggage compartment
foam holder ›››
 page 70.
● Store the spare wheel, the temporary spare
wheel or the ch
anged wheel securely in the
luggage compartment. ●
Have the tightenin
g torque of the wheel
bolts checked as soon as possible with a tor-
que wrench ››› page 38.
● Have the flat tyre replaced as quickly as
poss
ible.
Snow chains Use When using snow chains, applicable local
l
e
gi

slation and maximum permitted speed
limits must be observed.
In winter weather, snow chains not only help
to improve grip but also improve the braking
capacity.
The fitting of chains is permitted only on
front wheels and with the following combi-
nations of wheel trims and tyres :
Tyre sizeWheel rim
165/70 R145 J x 14 offset of 35175/65 R14 SEAT recommends you ask a technical serv-
ic
e f
or f

urther information on wheel, tyre and
chain sizes.
Wherever possible use fine-link chains meas-
uring less than 15 mm including the lock. Remove wheel hub covers and trim rings be-
fore fittin

g snow chains ››› . The wheel bolts
shou l
d be c
overed with caps for safety rea-
sons. These are available from technical serv-
ices.
Temporary spare wheel
For technical reasons, snow chains must not
be used on the compact temporary spare
wheel ›››
 page 207.
If it is necessary to fit chains with the tempo-
rary spare wheel in use, install the wheel on
the rear axle in the event of a fault in a front
wheel. Then, fit the rear wheel that is free, in-
stead of the damaged front wheel. In this sit-
uation, observe the rotating direction of the
wheels. SEAT recommends attaching the
snow chains before fitting the wheel. WARNING
The use of unsuitable or incorrectly fitted
ch ain

s could lead to serious accidents and
damage.
● Always the appropriate snow chains.
● Observe the fitting instructions provided by
the snow c
hain manufacturer.
● Never exceed the maximum permitted
speeds
when driving with snow chains. » 41

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. 42

The essentials
Driving style
T o
w
ing requires some experience, especially
when using a tow rope. Both drivers should
realise how difficult it is to tow a vehicle. In-
experienced drivers should not attempt to
tow.
Do not pull too hard with the towing vehicle
and take care to avoid jerking the tow rope.
When towing on an unpaved road, there is al-
ways a risk of overloading and damaging the
anchorage points.
Switch on the ignition so that the turn sig-
nals, windscreen wipers and windscreen
washer can work. Ensure that the steering
wheel is unlocked and moves freely.
Place the gear lever in neutral on vehicles
with a manual gearbox. With an automatic
gearbox, place the lever in N.
To brake, press the brake pedal firmly. The
brake servo does not work when the engine
is switched off.
The power steering only works when the igni-
tion is switched on and the vehicle is moving,
provided that the battery is sufficiently charg-
ed. Otherwise, it will need more force.
Ensure that the tow rope remains taut at all
times. ››› in Instructions for tow-starting on
page 76
››› page 75 Tow-starting
In general, the vehicle should not be started
by
t

owing. Jump-starting is much more pref-
erable ››› page 43.
For technical reasons, the following vehicles
can not be tow started:
● Vehicles with an automatic gearbox.
● If the vehicle battery is flat, it is possible
that the en

gine control unit does not operate
correctly.
However, if your vehicle must absolutely be
tow-started (manual gearbox):
● Put it into second or third gear.
● Keep the clutch pressed down.
● Switch on the ignition and the hazard warn-
ing lights.
● Rel

ease the clutch when both vehicles are
movin
g.
● As soon as the engine starts, press the
clutc
h and move the gear lever into neutral.
This helps to prevent a collision with the tow-
ing vehicle. How to jump start
Jump lea
ds If the engine fails to start because of a dis-
ch
ar

ged battery, the battery of another vehi-
cle can be used to start the engine. Before
starting, check the magic eye on the battery
›››  page 196.
For starting assistance, jump lead cables con-
forming to the standard DIN 72553 are re-
quired (see the cable manufacturer instruc-
tions). The cable section in vehicles with pet-
rol engine must be at least 25 mm 2
. WARNING
Incorrect use of jump leads and incorrectly
jump st ar

ting could cause the battery to ex-
plode resulting in serious injury. Please ob-
serve the following rules to minimise the risk
of a battery explosion:
● The battery providing current must have
the same v
oltage (12V) and approximately
the same capacity (see markings on battery)
as the flat battery.
● Never charge a frozen or recently thawed
batter
y. A flat battery can also freeze at tem-
peratures close to 0°C (+32°F).
● If a battery is frozen and/or has been frozen
then it mus
t be replaced.
● A highly explosive mixture of gases is re-
lea
sed when the battery is being charged. Al-
ways keep lit cigarettes, flames, sparks and » 43

Safety
Safety equipment Never put your safety or the safety of your
pa
s
sengers in danger. In the event of an acci-
dent, the safety equipment may reduce the
risk of injury. The following points cover part
of the safety equipment in your SEAT:
● three-point seat belts,
● belt tension limiters for the front seats,
● Belt tensioners for the front seats,
● front airbags,
● side airbags in the front seat backrests,
● “ISOFIX” anchor points for child seats in
the re ar s

ide seats with the “ISOFIX” system,
● rear head restraints with in-use position
and non-use pos
ition,
● adjustable steering column.
The safety
equipment mentioned above
works together to provide you and your pas-
sengers with the best possible protection in
the event of an accident. However, these
safety systems can only be effective if you
and your passengers are sitting in a correct
position and use this equipment properly.

a
s

sengers are shown below. If your physical constitution prevents you
from maint

aining the correct sitting position,
contact a specialised workshop for help with
any special devices. The seat belt and airbag
can only provide optimum protection if a cor-
rect sitting position is adopted. SEAT recom-
mends taking your car in for technical serv-
ice.
For your own safety and to reduce the risk of
injury in the event of an accident or sudden
braking or manoeuvre, SEAT recommend the
following positions:
Valid for the driver:
● Adjust the seat backrest to an upright posi-
tion so that
your back rests completely
against it.
● Adjust the seat so that there is a distance
of at l
east 25 cm between the steering wheel
and your chest ››› Fig. 64 and so that you can
hold the steering wheel with both hands on
the outside of the ring at the 9 o'clock and 3
o'clock positions with your arms slightly
bent.
● The adjusted steering wheel must face your
ches
t and not your face.
● Adjust the driver seat forwards or back-
ward
s so that you are able to press the accel-
erator, brake and clutch pedals to the floor
with your knees slightly angled and the dis-
tance between your knees and the dash pan-
el is at least 10 cm ››› Fig. 64.

Safe driving
● Adju s
t
the height of the driver seat so that
you can easily reach the top of the steering
wheel.
● Keep both feet in the footwell so that you
have the
vehicle under control at all times.
● Adjust and fasten your seat belt correctly
›››
page 52.
Valid for the passenger:
● Adjust the seat backrest to an upright posi-
tion so that
your back rests completely
against it.
● Move the front passenger seat back as far
as po
ssible for optimum protection should
the airbag deploy.
● Always keep your feet in the footwell while
the vehic
le is in motion.
● Adjust and fasten your seat belt correctly
›››
page 52.
Valid for the passengers in the rear section:
● 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
restraint ››› Fig. 64 and ››› Fig. 65.
● Short people must lower the head restraint
to the fir s

t anchorage position, even if your
head is below its upper edge. ●
Tal l

people must raise the head restraint
completely.
● Always keep your feet in the footwell while
the vehic
le is in motion.

Incorrect use of the steering wheel adjust-
ment f u

nction and an incorrect adjustment of
the steering wheel can result in severe or fa-
tal injury.
● After adjusting the steering column, push
the lever firm
ly upwards to ensure the steer-
ing wheel does not accidentally change posi-
tion while driving.
● Never adjust the steering wheel while the
vehicl
e is in motion. If you need to adjust the
steering wheel while the vehicle is in motion,
stop safely and make the proper adjustment. ●
The adju s

ted steering wheel should be fac-
ing your chest and not your face so as not to
hinder the driver's front airbag protection in
the event of an accident.
● When driving, always hold the steering
wheel with both h
ands on the outside of the
ring at the 9 o'clock and 3 o'clock positions
to reduce injuries when the driver's front air-
bag deploys.
● Never hold the steering wheel at the 12
o'clock
position or in any other manner (e.g.
in the centre of the steering wheel). In such
cases, if the driver's airbag deploys, you may
sustain injuries to your arms, hands and
head. Danger of injuries due to an incorrect

sition Number of seats
The
v

le has a total of 4 seats: 2 front
seats and 2 rear seats. Each seat is equipped
with a seat belt.
If the seat belts are worn incorrectly or not at
all, the risk of severe injuries increases. Seat
belts can provide optimal protection only if
the belt web is properly worn. Being seated
in an incorrect position means the seat belt
cannot offer its full protection. This could re-
sult in severe and even fatal injuries. The risk »

Safety

Safety
of severe or fatal injuries is especially height-
ened when a dep lo
y
ing airbag strikes a vehi-
cle occupant who has assumed an incorrect
sitting position. The driver is responsible for
all passengers in the vehicle, particularly
children.
The following list shows just some examples
of incorrect sitting positions which can be
dangerous to all vehicle occupants.
When the vehicle is in motion:
● Never stand in the vehicle.
● Never stand on the seats.
● Never kneel on the seats.
● Never tilt your seat backrest too far to the
rear
.
● Never lean against the dash panel.
● Never lie on the rear seats.
● Never sit on the front edge of a seat.
● Never sit sideways.
● Never lean out of a window.
● Never put your feet out of a window.
● Never put your feet on the dash panel.
● Never put your feet on the surface of a seat
or seat b
ackrest.
● Never travel in a footwell.
● Never travel on a seat without wearing the
seat belt
. ●
Never carr
y any person in the luggage com-
partment. WARNING
An incorrect sitting position in the vehicle
can l e

ad to severe injuries or death in the
event of sudden braking or manoeuvres, colli-
sion or accidents or if the airbag deploys.
● Before the vehicle moves, assume the prop-
er sitting po
sition and maintain it throughout
the trip. This also includes fastening the seat
belt.
● Never transport more people than there are
seats
with a seat belt available in the vehicle.
● Children must always be protected with an
appro
ved child restraint system suited to
their height and weight ››› page 64,
››› page 58.
● Always keep your feet in the footwell while
the vehic
le is in motion. Never, for example,
put your feet on the surface of a seat or on
the dash panel and never put them out of a
window. Otherwise the airbag and seat belt
offer insufficient protection and the risk of in-
jury in the event of an accident is increased. WARNING
Before every trip, adjust the seat, the seat
belt and the he a

d restraints and instruct your
passengers to fasten their seat belts proper-
ly.
● Move the front passenger seat back as far
as po
ssible. ●
Adjus t

the driver seat so that there is at
least 25 cm distance between your chest and
the hub of the steering wheel. Adjust the
driver seat so that you are able to press the
accelerator, brake and clutch pedals to the
floor with your knees slightly angled and that
the distance between your knees and the
dash panel is at least 10 cm. If your physical
constitution prevents you from meeting these
requirements, contact a specialised work-
shop to make any modifications required.
● Never drive with the seat backrest tilted far
back.
The further the seat backrests are tilted
to the rear, the greater the risk of injury due
to incorrect positioning of the belt web or to
the incorrect sitting position!
● Never drive with the seat backrest tilted
forw
ards. Should a front airbag deploy, it
could throw the seat backrest backwards and
injure the passengers of the rear seats.
● Sit as far away as possible from the steer-
ing wheel and the d
ash 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. 50

Seat belts
Head-on collisions and the laws of
ph y
s
ics Fig. 70
A driver not wearing a seat belt is
thr o
wn f

orward violently. Fig. 71
The unbelted passenger in the rear

i

s thrown forward violently, hitting the
driver who is wearing a seat belt. It is easy to explain how the laws of physics
w
ork
in the c

ase of a head-on collision: when
a vehicle starts moving, a type of energy called “kinetic energy” is created both in the
pas

sengers and inside the vehicle.
The amount of “kinetic energy” depends on
the speed of the vehicle and on the weight of
the vehicle and of its passengers. The higher
the speed and the greater the weight, the
more energy there is to be “absorbed” in an
accident.
The most significant factor, however, is the
speed of the vehicle. If the speed doubles
from 25 km/h (15 mph) to 50 km/h
(30 mph), for example, the corresponding ki-
netic energy is multiplied by four.
Because the vehicle occupants in our exam-
ple are not restrained by seat belts, in the
event of crashing against a wall, all of the oc-
cupants' kinetic energy will be absorbed
solely by said impact.
Even at speeds of 30 km/h (19 mph) to
50 km/h (30 mph), the forces acting on bod-
ies in a collision can easily exceed one tonne
(1000 kg). At greater speed these forces are
even higher.
Vehicle occupants not wearing seat belts are
not “attached” to the vehicle. In a head-on
collision, they will move forward at the same
speed their vehicle was travelling just before
the impact. This example applies not only to
head-on collisions, but to all accidents and
collisions. Even at low speeds the forces acting on the
body in a co
llision are so great that it is not
possible to brace oneself with one's hands.
In a frontal collision, unbelted passengers
are thrown forward and will make violent con-
tact with the steering wheel, dash panel,
windscreen or whatever else is in the way
››› Fig. 70.
It is also important for rear passengers to
wear seat belts properly, as they could other-
wise be thrown forward violently through the
vehicle interior in an accident. Passengers in
the rear seats who do not use seat belts en-
danger not only themselves but also the front
occupants ››› Fig. 71.
