The essentials
8. Start the engine of the vehicle with the flat batt
er
y and wait for 2 or 3 minutes until
the engine is running.
Removing the jump leads
9. Before you remove the jump leads, switch off the dipped be
am headlights (if they
are switched on).
10.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 discon-
nected.
11.
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, switch off the start-
er after about 10 seconds and try again after
about 1 minute. WARNING
● Ple a

se note the safety warnings referring to
working in the engine compartment
›››  page 184.
● The battery providing assistance must have
the same v
oltage as the flat battery (12V) and
approximately the same capacity (see imprint 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.
● Do not attach the negative cable from the
other vehic
le to parts of the fuel system or to
the brake line.
● 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
positive terminals are connected. Changing the wiper blades

Operation
●
In the event of
smells, switch off the seat
heating immediately and have the unit in-
spected by a specialised workshop. For the sake of the environment
The seat heating should remain on only when
needed. Other wi

se, it is an unnecessary fuel
waste. Transport and practical
equipment
T r
an

sporting objects
Introduction Always transport heavy loads in the luggage
comp
ar

tment and place the seat backs in a
vertical position. Never overload the vehicle.
Both the carrying capacity as well as the dis-
tribution of the load in the vehicle affect driv-
ing behaviour and braking ability ››› .
WARNING
Unsecured or incorrectly secured objects can
cau se seriou

s injury in case of a sudden ma-
noeuvring or breaking or in case of an acci-
dent. This is especially true when objects are
struck by a detonating airbag and fired
through the vehicle interior. To reduce the
risks, please note the following:
● Secure all objects in the vehicle. Always
keep equipment and he
avy objects in the lug-
gage compartment.
● Always secure objects with suitable rope or
sling
s so that they cannot enter the deploy-
ment areas around the frontal or side airbags
in case of sudden braking or an accident.
● Always ensure that objects inside the vehi-
cle c
annot move into the deployment area of
the bags while driving. ●
Whil e driv

ing, always keep object compart-
ments closed.
● Remove all objects from the front passen-
ger seat
when it is folded down. When the
seat backrest is folded down, it presses on
small and light objects and these are detec-
ted by the weight sensor on the seat; this
sends false information to the airbag control
unit.
● While the backrest of the front passenger
seat i
s folded, the frontal airbag must remain
disconnected and the PASSENGER AIRBAG
OFF  light on.
● Objects secured in the vehicle should never
be plac
ed in such a way as to make passen-
gers sit in an incorrect position.
● If secured objects occupy a seat, this seat
should not
be occupied or used by anyone. WARNING
The driving behaviour and braking ability
ch an

ge when transporting heavy and large
objects.
● Adjust your speed and driving style to visi-
bility
, road, traffic and weather conditions.
● Accelerate gently and carefully.
● Avoid sudden braking and manoeuvres.
● Brake early. 110

Driving
● When l e
av
ing the vehicle, take all keys with
you.
● Lock the vehicle.
Additiona
l information for steep slopes and
hills
Before switching off the engine, rotate the
steering wheel so that if the vehicle should
move, it will be held by the kerb.
● On slopes, turn the front wheels so that
they are ag
ainst the edge of the kerb.
● Uphill, turn the wheels towards the centre
of the ro
ad. WARNING
The components of the exhaust system reach
ver y

high temperatures. This could cause a
fire and considerable damage.
● Always park your vehicle so that no part of
the exhau
st system can come in contact with
flammable materials (such as wood,
leaves,dried grass, or spilled fuel). CAUTION
● Spec i

al care should be taken when parking
in areas with high kerbs or fixed barriers. Ob-
jects protruding from the ground may dam-
age the bumper or other parts of the vehicle
during manoeuvres. To avoid damage, stop
before the wheels touch the barrier or kerb. ●
Spec i

al attention is required when driving
through entrances, over ramps, kerbs or oth-
er objects. The vehicle underbody, bumpers,
mudguards and running gear, and the engine
and exhaust system could be damaged as
you drive over these objects. Information on the brakes
For the first 200 to 300 km, the new brak
e
p
ads have not yet reached their maximum
braking capacity, and need to be “run in”
first ››› . The slightly reduced braking effect
c an be c
ompen

sated for by increasing pres-
sure on the brake pedal. While running in,
the full braking distance or emergency brak-
ing distance is larger then when the brake
pads have been run in. While running in,
avoid full power braking or situations requir-
ing braking performance. For example, in
heavy traffic.
The rate of wear of the brake pads depends
to a great extent on the conditions in which
the vehicle is used and the way the vehicle is
driven. If the vehicle is used frequently in city
traffic or for short trips or driven sport style,
visit a specialised workshop regularly, more
frequently than advised in the Maintenance
Programme, to have the brake pads checked.
If you drive with wet brakes, for example, af-
ter crossing areas of water, in heavy rainfall
or even after washing the car, the effect of the brakes is lessened as the brake discs are
wet or ev

en frozen (in winter). At higher
speed, “dry” the brakes as quickly as possi-
ble by braking gently several times. Only do
this without endangering vehicles behind
you or any other road users ››› .
A l a
y

er of salt on the discs and brake pads
will reduce the effectiveness of the brakes
and increase braking distance. If you drive for
a prolonged period on salted roads without
braking then brake carefully several times to
eliminate the layer of salt on the brakes ››› .
If the
v

ehicle remains parked for considera-
ble lengths of time, is used little, or if the
brakes are not used, there may be corrosion
on the brake discs and a build up of dirt on
the brake pads. If the brakes are not used fre-
quently, or if rust has formed on the discs,
SEAT recommends cleaning the pads and
discs by braking firmly a few times at a mod-
erately high speed. Only do this without en-
dangering vehicles behind you or any other
road users ››› .
F au
lt

s in the brake system
During braking, if you notice that the vehicle
does not react as usual (that the braking dis-
tance has increased suddenly) it may be pos-
sible that there is a fault in the braking sys-
tem. This is indicated by the warning lamp
. Take the vehicle to a specialised work-
shop immediately and have the fault re-
paired. Drive at a moderate speed and be »

The catalytic converter permits the subse-
quent tr
e

atment of the exhaust gases thus
reducing contaminating gas emissions. To
ensure a longer working life for the exhaust
system and catalytic converter in a petrol en-
gine:
● Always use unleaded petrol.
● Never run the fuel tank completely dry.
● Do not top up with too much engine oil

If you should notice misfiring, uneven run-
ning or loss of power when the car is moving,
reduce speed immediately. Have the car in-
spected by a specialised workshop. If this
happens, unburnt fuel can enter the exhaust
system and escape into the atmosphere. The
catalytic converter can also be damaged by
overheating. »

e substance. Incorrect handling of the
natural gas can cause accidents serious
burns and other injuries. ●
Bef or

e refuelling with natural gas, the fill-
ing mouth must be correctly engaged. If you
can smell gas, stop refuelling immediately. WARNING
The vehicle is not prepared to use liquefied
n at ur

al gas (LNG) and this fuel must not be
added under any circumstances. Liquefied
natural gas can cause the natural gas tank to
explode, resulting in serious injury. Note
● The fil lin

g nozzles of natural gas pumps
can differ in the way they are operated. If you
are unacquainted with the pump, it is advisa-
ble that a member of staff of the service sta-
tion performs the refuelling operation.
● Noises heard when refuelling are normal
and do not indicat
e the presence of a fault in
the system.
● The vehicle natural gas system is prepared
both for ref
uelling with a small compressor
(slow refuel) and a large compressor (fast re-

 page 10 Before working in the engine compartment,
make s

ure that the vehicle is parked on hori-
zontal and firm ground.
The engine compartment of the vehicle is a
hazardous area. Never work on the engine or
in the engine compartment if you are not fa-
miliar with the operations to be carried out,
the applicable safety standards and especial-
ly if you do not have the necessary instru-
ments, liquids and tools ››› ! If required,

workshop. Negligent work can cause serious
injury. WARNING
If the vehicle moves unexpectedly, this could
cau se seriou

s injury.
● Never work under the vehicle if it has not
been immobi
lized. If you must work under-
neath the vehicle with the wheels in contact
with the ground then it should be parked on
flat ground, the wheels should be prevented
from moving and the key should be removed
from the ignition.
● If you have to work underneath the vehicle,
you mus

Advice
The service life of tyres is dependent on tyre
pr e
s
sure, driving style, the care they receive
and the correct fitting.
The tyres and wheel rims are an essential
part of the vehicle's design. The tyres and
rims approved by SEAT are specially matched
to the characteristics of the vehicle and our
critical to good road holding and safe han-
dling.
Avoiding damage to tyres and wheels
● If you have to drive over a kerb or similar
obs
tacle, drive very slowly and as near as
possible at a right angle to the kerb.
● Inspect the tyres regularly for damage
(punct
ures, cuts, cracks, dents).
● Remove any foreign bodies found on the
outside of the ty
re tread and ensure that they
have not passed through the wall of the tyre
››› page 202.
● In addition, the instructions for tyre control
syst
ems should always be observed.
● Replace damaged or worn tyres as soon as
poss
ible ››› page 202.
● Regularly check tyres for non-visible dam-
age ››

› page 202.
● Never exceed the maximum permitted
speed or loa
ds specified for the type of tyre
fitted on your vehicle ››› page 205.
● Do not allow tyres (including the spare
wheel) to come int
o contact with aggressive substances, grease, oil, fuel or brake fluid
›››
.
● Lost valve caps should be replaced imme-
di at
ely

.
Tyres with directional tread pattern
Tyres with directional tread pattern have
been designed to operate best when rotating
in only one direction. An arrow on the tyre
sidewall indicates the direction of rotation on
tyres with directional tread ››› page 205. Al-
ways observe the direction of rotation indica-
ted when mounting the wheel. This guaran-
tees optimum grip and helps to avoid aqua-
planing, excessive noise and wear.
If the tyre is mounted in the opposite direc-
tion of rotation, drive with extreme caution,
as the tyre is no longer being used correctly.
This is of particular importance when the
road surface is wet. Change the tyre as soon
as possible or remount it with the correct di-
rection of rotation.
Interchanging tyres
To ensure that the wear is equal on all tyres
the wheels should be changed round from
time to time according to the system
››› Fig. 172. The useful life of all the tyres will
then be about the same time.
SEAT recommends you take the vehicle to a
specialised workshop to have the tyres
changed. Tyres over 6 years old
Tyr

es are subject to an ageing process as a
result of physical and chemical processes.
This may affect their performance. Tyres
which are stored for long periods of time
without being used, harden and become
more fragile than tyres which are in constant
use.
SEAT recommends that tyres over six years
old are replaced with new tyres. This also ap-
plies to tyres (including the spare wheel)
which appear to be in perfect condition on
the outside and which have a tread depth
within the values stipulated by the Law ››› .
The d at
e of

manufacture, part of the tyre
identification number (TIN), indicates the age
of the tyre ( ) ››› page 205.
Storing tyres
Mark tyres when you remove them to indicate
the direction of rotation (left, right, forwards,
backwards). This ensures you will be able to
mount them correctly when you replace
them. When removed, the wheels and/or
tyres should be stored in a cool, dry and pref-
erably dark location. Do not place tyres
mounted on the wheel in a vertical position.
Protect tyres not mounted on wheels from
dirt by storing them in suitable bags and
standing them on the ground on their tread.

Under-inflation or over-inflation will reduce
the life of the tyres considerably and also im-
pair the car's handling ››› . It is essential to
m aint
ain the c

orrect tyre pressures, especial-
ly if driving at high speeds. Incorrect tyre
pressure causes premature wear and could
cause tyre blow-out.
The pressure should therefore be checked at
least once a month and before starting a
journey.
As a general rule, the pressures given are for
cold tyres. When the tyres are hot, the pres-
sures are greater.
Never deflate a hot tyre in order to obtain the
required pressure. This could result in very
low tyre pressures which may lead to sudden
blow-outs.
Tyre pressure monitoring system
Check tyre pressures only when the vehicle
has not been driven for more than a few kilo-
metres at low speeds in the past three hours.
● The tyre pressures should be checked regu-
larly, and on
ly when the tyres are cold. Al-
ways check all tyres, including the spare
wheel. Tyre pressures should be checked
more often in colder regions, and only when
the vehicle has not been driven recently. Al-
ways use a correctly-operating tyre gauge. ●
Adjust
tyre pressures to the loads carried in
the vehicle.
● After adjusting the tyre pressure, check that
the caps
are properly screwed on.
The spare wheel or temporary spare wheel
must always be kept at the maximum pres-
sure stipulated. WARNING
If tyre pressures are too high or too low, the
tyr e m

ay deflate or burst suddenly while driv-
ing. This could result in a serious accident.
● If the tyre pressure is too low, they could
overhe
at, resulting in tread detachment or
even burst tyres.
● When driving at high speeds and/or fully
loaded, the ty
re could suddenly overheat,
burst or be subject to tread detachment, with
the resultant loss of control of the vehicle.
● Tyre pressures which are too high or too
low reduc
e the service life of the tyre, affect-
ing the vehicle's performance.
● Tyre pressures should be checked regularly,
at le
ast once a month and before long jour-
neys.
● Adjust the pressures of all the tyres to the
vehicl
e load.
● Never deflate excess pressure from hot
tyre
s. CAUTION
● Tak e c

are not to tilt the manometer when
placing it on the valve. Otherwise, the valve
may be damaged.
● If tyre valves are not protected by caps, or if
the caps
are not screwed on correctly, they
may become damaged. Check that the caps
are identical to the standard caps and have
been correctly tightened. For the sake of the environment
Under-inflated tyres will increase fuel con-
sumption. Wear indicator depth profile
