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.

● 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
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
The seat belt status flashes for a maximum of
30 sec ond
s
when a seat belt in the rear seats
is unfastened while the vehicle is in motion.
An audible warning will also be heard if the
vehicle is travelling at over 25 km/h
(15 mph).
The protective function of seat belts Fig. 69
Drivers with properly worn seat belts
w i
l

l not be thrown forward in the event of sud-
den braking. Properly worn seat belts hold the occupants
in the pr
oper po
s

ition. They also help prevent
uncontrolled movements that may result in
serious injury and reduce the risk of being
thrown out of the vehicle in case of an acci-
dent.
Vehicle occupants wearing their seat belts
correctly benefit greatly from the ability of the
belts to absorb kinetic energy. In addition, the front part of your vehicle and other pas-
sive s

afety features (such as the airbag sys-
tem) are designed to absorb the kinetic ener-
gy released in a collision. Taken together, all
these features reduce the releasing kinetic
energy and consequently, the risk of injury.
This is why it is so important to fasten seat
belts before every trip, even when "just driv-
ing around the corner".
Ensure that your passengers wear their seat
belts as well. Accident statistics have shown
that wearing seat belts is an effective means
of substantially reducing the risk of injury
and improving the chances of survival when
involved in a serious accident. Furthermore,
properly worn seat belts improve the protec-
tion provided by airbags in the event of an
accident. For this reason, wearing a seat belt
is required by law in most countries.
Although your vehicle is equipped with air-
bags, the seat belts must be fastened and
worn. The front airbags, for example, are only
triggered in some cases of head-on collision.
The front airbags will not be triggered during
minor frontal or side collisions, rear-end colli-
sions, rollovers or accidents in which the air-
bag trigger threshold value in the control unit
is not exceeded.
Therefore, you should always wear your seat
belt and ensure that all vehicle occupants
have fastened their seat belts properly before
you drive off! 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.54

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.

Belt tension limiter
The belt tension limiter reduces the force of
the seat belt on the body in the event of an
accident. Note
The relevant safety requirements must be ob-
serv ed when the

vehicle is dismantled or sys-

s If you work on the belt tensioners or remove
and in
s
t

all other parts of the vehicle when
performing other repair work, the seat belt
may be damaged. The consequence may be
that, in the event of an accident, the belt ten-
sioners function incorrectly or not at all. So that the effectiveness of the belt tensioner
is not

reduced and that removed parts do not
cause any injuries or environmental pollu-
tion, regulations must be observed. These re-
quirements are known to specialised work-
shops. WARNING
● Improper u se or r

cumstances.
● Never attempt to repair, adjust, remove or

belts.
● The seat belt tensioner, seat belt and auto-

● Any work on the belt tensioners and seat
belts, includin
g the removal and refitting of
system parts in conjunction with other repair
work, must be performed by a specialised
workshop only.

Brief intr
oduction
Intr

oduction Front airbags have been installed for both
driver and p
a

ssenger. The front airbags can
also protect the chest and head of driver and
passenger if the seats, seat belts head re-
straints and, for the driver, the steering
wheel are correctly adjusted and used. Air-
bags are considered as additional safety
equipment. An airbag cannot replace the
seat belt, which must be worn at all times,
even in front seats where front airbags have
been installed.
The airbag can protect vehicle occupants in
the event of an accidents, cushioning the
movement of the occupants in the direction
of the collision in frontal and side accidents.
Deployed airbags fill with a propellant gas.
This causes the airbag covers to break and
the airbags to deploy extremely quickly in
their entire deployment space within frac-
tions of a second. When an occupant with the
seat belt properly fastened puts pressure on
the inflated airbag, the propellant gas es-
capes to absorb the force of the impact and
slow the movement. This reduces the risk of
severe or fatal injuries. Airbag deployment
does not mean that other types of injury such
58

Airbag system
as swelling, bruising and skin injuries can be
ru l
ed out
. Upon deployment of the airbag,
friction can cause the generation of heat.
Airbags do not protect the arms or the lower
part of the body.
The most important factors for triggering the
airbag are the type of accident, the angle of
impact, the vehicle speed and the character-
istics of the object the vehicle hits. Therefore,
airbags are not triggered every time the vehi-
cle is visibly damaged.
The activation of the airbag system depends
on the magnitude of the deceleration of the
vehicle caused by a collision, which registers
through an electronic control unit. If the de-
celeration magnitude value is below the ref-
erence value programmed in the control unit,
the airbags will not deploy even though seri-
ous damage might be caused to the vehicle
as the result of an accident. Damage suffered
by the vehicle, reparation costs or absence of
damage suffered from the accident are not
indications of whether an airbag should have
been deployed. Due to the varying nature of
collision situations, it is impossible to define
a speed range of the vehicle and reference
values. For this reason, it is not possible to
cover all types of collisions and collision an-
gles resulting in the deployment of the air-
bag. Factors necessary for the airbag to be
deployed can be, the characteristics of the
object (hard or soft) against which the vehi- cle collides, the collision angle and the vehi-
cle s
peed.
Airbags act in conjunction with the three-
point seat belts in certain accident situa-
tions, when the vehicle deceleration rate is
severe enough to trigger the airbags. Airbags
only deploy once and only under certain cir-
cumstances. Seat belts remain present to of-
fer protection in situations where airbags are
not triggered or where they have already de-
ployed. For example, when a vehicle hits an-
other after an initial collision or is hit by an-
other vehicle.
The airbag system is an integral part of the
car's passive safety system. The airbag sys-
tem can only work effectively when the vehi-
cle occupants are wearing their seat belts
correctly and have adjusted the head re-
straints properly  ››› page 48. WARNING
Never exclusively trust the airbag system as a
mean s

of protection.
● Even when triggered, airbag protection is
only aux
iliary.
● The airbags provide the best protection
when the seat belt
s are properly fastened,
thus reducing the risk of sustaining injuries
››› page 52, Why wear a set belt .
● Before each trip, every occupant must sit
properly, c
orrectly fasten the seat belt be-
longing to his or her seat and keeping it fas- tened throughout the trip. This rule is valid
for a
l

l 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. » 59
