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

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 36. 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. 39

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 75
››› page 74 Tow-starting
In general, the vehicle should not be started
by
t

owing. Jump-starting is much more pref-
erable ››› page 42.
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 193.
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 42

orrect sitting position. Instruct
your passengers also to assume a proper
sitting position. ››› page 47.
– Fasten your seat belt securely. Instruct your
pas

sengers also to fasten their seat belts
properly. ››› page 51.
What affects driving safety? As a driver, you are responsible for yourself
and y
our p

assengers. When your concentra-
tion or driving safety is affected by any cir-
cumstance, you endanger yourself as well as
others on the road ››› , for this reason:
– Always pay attention to traffic and do not
g et
di

stracted by passengers or telephone
calls.
– Never drive when your driving ability is im-
paired (e.

g. by medication, alcohol, drugs).
– Observe traffic laws and speed limits.
– Always reduce your speed as appropriate
for ro

ad, traffic and weather conditions.
– When travelling long distances, take
break

s regularly - at least every two hours.
– If possible, avoid driving when you are tired
or stre

ssed.

Safe driving
Danger of injuries due to an incorrect
s ittin
g po
sitionNumber of seats
The v
ehic

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
of severe or fatal injuries is especially height-
ened when a deploying 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
re ar

.
● Never lean against the dash panel. ●
Never lie on the re
ar 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 carry 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 63,
››› 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 da
sh p

anel 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.
● Adjust the driver seat so that there is at
lea
st 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. » 49

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

Using seat belts Twisted seat belt
If it
i
s difficult to remove the seat belt from
the guide, the seat belt may have become
twisted inside the side trim after being
wound too quickly on unfastening:
● Pull out the seat belt completely, carefully
pul
ling on the latch plate.
● Untwist the belt and guide it back, assist-
ing it b
y hand.
The seat belt must be fastened even if it is
impossible to untwist it. In this case, the
twisted area must not be in an area in direct
contact with your body. Have the seat belt
untwisted urgently by a specialised work-
shop. WARNING
An improperly handled seat belt increases
the risk of

sustaining severe or fatal injuries.
● Regularly check that the seat belts and
their components
are in perfect condition.
● Always keep your seat belt clean.
● Do not jam or damage the seat belt or rub it
with sharp edg
es.
● Make sure there are no liquids or foreign
bodies on the l
atch plate and in the buckle. Head-on collisions and the laws of

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 the weight of
the vehicle and 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.

Airbag system
●
Bef or
e each trip, every occupant must sit
properly, correctly fasten the seat belt be-
longing to his or her seat and keeping it fas-
tened throughout the trip. This rule is valid
for all vehicle occupants. WARNING
Occupants sitting in the front of the vehicle
mu st

never carry any objects in the deploy-
ment space between them and the airbags,
as this increases the risk of sustaining inju-
ries if the airbag is triggered. This modifies
the airbag deployment space or the objects
may fly uncontrollably and hit your body.
● Never carry objects in your hand or on your
lap whil
e the vehicle is in motion.
● Never transport objects on the front pas-
senger se
at. In the event of sudden braking
and manoeuvres, the objects may end up in
the airbag deployment space and fly uncon-
trollably around the interior if the airbag is
activated.
● Occupants of the front and rear seats must
never carr
y any other people, pets or objects
in the deployment space between them and
the airbags. Make sure children and other
passengers also respect this recommenda-
tion. WARNING
The airbag system provides protection for
one acc ident

only. If they have been de-
ployed, they must be replaced. ●
Ens ur

e deployed airbags and the system
components involved are immediately re-
placed with new, SEAT-approved components
for the vehicle.
● Have any repairs or modifications carried
out at a s
pecialised workshop. Specialised
workshops have the necessary tools, diag-
nostics equipment, repair information and
qualified personnel.
● Never fit recycled or reused airbag compo-
nents in
your vehicle.
● Never modify the airbag system compo-
nents. WARNING
If the airbags are triggered, a fine dust is pro-
duced. Thi

s is normal and it is not an indica-
tion of fire in the vehicle.
● This fine dust may irritate the skin and eyes
and cause br
eathing difficulties, particularly
in people suffering from or who have suffered
from asthma or other illnesses of the respira-
tory tract. To reduce breathing difficulties,
get out of the vehicle and open and doors and
windows to breath in fresh air.
● Should you touch the dust, wash your
hands
and face using a mild soap and water
before you eat.
● Prevent the dust from affecting the eyes or
open wound
s.
● Rinse your eyes with water if you have dust
in them. WARNING
Solvents cause the surfaces of the airbag
modul e

s to become porous. If an airbag is ac-
cidentally triggered, the detachment of plas-
tic parts could cause serious injury.
● Never clean the dash panel and the surfa-
ces
of the airbag modules with cleaners con-
taining solvents. Description of airbag system

g. WARNING
● The seat belt

s and airbags can only provide
maximum protection if the occupants are
seated correctly ››› page 47.
● If a fault has occurred in the airbag system,
have the sy
stem checked immediately by a
specialised workshop. Otherwise, during a
frontal collision the system might not trigger
correctly or may fail to trigger at all. Airbag activation
The airbags deploy extremely rapidly, within
thou
s
andths

of a second, to provide addi-
tional protection in the event of an accident.
A fine dust may develop when the airbag de-
ploys. This is normal and it is not an indica-
tion of fire in the vehicle.
The airbag system is only ready to function
when the ignition is on.
In special accidents instances, several air-
bags may activate at the same time.
In the event of minor head-on and side colli-
sions, rear-end collisions, overturning or roll-
over of the vehicle, airbags do not activate.
Activation factors
The conditions that lead to the airbag system
activating in each situation cannot be gener-
alised. Some factors play an important role,
such as the properties of the object the vehi- cle hits (hard/soft), angle of impact, vehicle
speed, etc

.
Deceleration trajectory is key for airbag acti-
vation.
The control unit analyses the collision trajec-
tory and activates the respective restraint
system.
If the deceleration rate is below the prede-
fined reference value in the control unit the
airbags will not be triggered, even though
the accident may cause extensive damage to
the car.
