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

The essentials
fire far from the battery. Never use a mobile
tel
ephone when c
onnecting and removing the
jump leads.
● Charge the battery only in well ventilated
area
s given that when the battery is charged
by outside assistance, it creates a mix of
highly explosive gases.
● Jump leads should never enter into contact
with mov
ing parts in the engine compart-
ment.
● Never switch the positive and negative
pole
s or connect the jump leads incorrectly.
● Note the instruction manual provided by
the manufact
urer of the jump leads. CAUTION
To avoid considerable damage to the vehicle
electric a

l system, note the following careful-
ly:
● If the jump leads are incorrectly connected,
this c
ould result in a short circuit.
● The vehicles must not touch each other,
otherwi
se electricity could flow as soon as
the positive terminals are connected. How to jump start: description

The essentials
Start the engine of the vehicle with the
fl at
b
attery and wait for 2 or 3 minutes
until the engine is running.
Removing the jump leads Before you remove the jump leads,
switch off the dipped beam headlights if
they are switched on.
Turn on the heater blower and heated
rear window in the vehicle with the flat
battery. This helps minimise voltage
peaks which are generated when the
leads are disconnected.
When the engine is running, disconnect
the leads in reverse order to the details
given above.
Make sure the battery clamps have sufficient
metal-to-metal contact with the battery termi-
nals.
If the engine fails to start after about 10 sec-
onds, switch off the starter and try again after
about 1 minute. WARNING
● Ple a

se note the safety warnings referring to
working in the engine compartment
›››  page 187.
● The battery providing assistance must have
the same v
oltage as the flat battery (12V) and
approximately the same capacity (see imprint 8.

on battery). Failure to comply could result in
an exp
lo

sion.
● Never use jump leads when one of the bat-
teries
is frozen. Danger of explosion! Even af-
ter the battery has thawed, battery acid could
leak and cause chemical burns. If a battery
freezes, it should be replaced.
● Keep sparks, flames and lighted cigarettes
awa
y from batteries, danger of explosion.
Failure to comply could result in an explo-
sion.
● Observe the instructions provided by the
manufact
urer of the jump leads.
● Do not connect the negative cable from the
other vehic
le directly to the negative terminal
of the flat battery. The gas emitted from the
battery could be ignited by sparks. Danger of
explosion.
● Never attach the negative cable to fuel sys-
tem component
s or the brake lines in the oth-
er vehicle.
● The non-insulated parts of the battery
clamp
s must not be allowed to touch. The
jump lead attached to the positive battery
terminal must not touch metal parts of the ve-
hicle, this can cause a short circuit.
● Position the leads in such a way that they
cannot c
ome into contact with any moving
parts in the engine compartment.
● Do not lean on the batteries. This could re-
sult
in chemical burns. Note
The vehicles must not touch each other, oth-
erw i

se electricity could flow as soon as the

Safety
●
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

lision.
● In fr

ontal collisions, when the deceleration
meas
ured by the control unit is too low.
● In minor side collisions.
● In rear collisions.
● In the event of the vehicle overturning.
● When the impact speed is lower than the
refer
ence value set in the control unit.
There is a fault in the system if the control

Airbag system
WARNING
● The seat belt
s and airbags can only provide
maximum protection if the occupants are
seated correctly ››› page 48.
● 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.
The following airbags are triggered in seri-
ous head-on collisions ● Driver airbag.
● Front passenger front airbag
The fol
lowing airbags are triggered in seri-
ous side-on collisions
● Front side airbag on the side of the acci-
dent.
● Re

ar side airbag on the side of the acci-
dent.
In an acc

ident with airbag activation:
● the interior lights switch on (if the interior
light swit
ch is in the courtesy light position);
● the hazard warning lights switch on;
● all doors are unlocked; ●
the fuel s
upply to the engine is cut.

se a

ssignments based on equipment and
the use of the same fuse for various electrical
components, it is not possible to provide an
up-to-date summary of the fuse positions for
the electrical components at the time of
printing this manual. For detailed information
about the fuse positions, please consult a
technical service.
In general, a fuse can be assigned to various
electrical components. Likewise, an electrical
component can be protected by several
fuses.
Only replace fuses when the cause of the
problem has been solved. If a newly inserted
fuse blows after a short time, you must have
the electrical system checked by a special-
ised workshop as soon as possible. WARNING
The high voltages in the electrical system can
give seriou s

electrical shocks, causing burns
and even death!
● Never touch the electrical wiring of the igni-
tion syst
em. ●
Tak e c

are not to cause short circuits in the
electrical system. WARNING
Using unsuitable fuses, repairing fuses or
bridgin g a curr

ent circuit without fuses can
cause a fire and serious injury.
● Never use a fuse with a higher value. Only
repl
ace fuses with a fuse of the same amper-
age (same colour and markings) and size.
● Never repair a fuse.
● Never replace a fuse by a metal strip, staple
or simil
ar. CAUTION
● To pr ev

ent damage to the vehicle's electric
system, before replacing a fuse always turn
off the ignition, the lights and all electrical
elements and remove the key from the igni-
tion.
● If you replace a fuse with higher-rating
fuse,
you could cause damage to another part
of the electrical system.
● Protect the fuse boxes when open to pre-
vent the entr
y of dust or humidity as they can
damage the electrical system. Note
● One component m

ay have more than one
fuse. 78
