This only applies to vehicles with the fuel gauge on the dash panel display.
Several warning and indication lamps light
up for a few seconds when the ignition is
switched on, signalling that the function is
being verified. They will switch off after a few
seconds.
In natural gas engines
The warning lamp  lights up when both fuel
types (petrol and natural gas) have reached
reserve level.
The warning lamp  lights up when the vehi-
cle is running in natural gas operating mode.
The warning lamp  switches off when the
natural gas is exhausted. The engine
changes to operate with petrol.
Problem: if the vehicle is left parked for a
long time just after refuelling, the gas level
indicator does not accurately indicate the
same level shown after refuelling when the
vehicle is started up again. This is not due to
a leak in the system, but to a drop in pres-
sure in the gas tank for technical reasons af- ter a cooling phase immediately after refuel-
ling. WARNING
Driving with insufficient fuel reserve could re-
su lt

in the vehicle breaking down in traffic
and a serious accident.
● If the fuel level is too low then the fuel sup-
ply t
o the engine can become irregular espe-
cially on slopes.
● If the engine “is choked” or stalls due to
lack
of or irregularity of the fuel supply, the
power steering as well as all of the driver as-
sistance systems including braking assis-
tance will stop working.
● Always refuel when there is only one quar-
ter of the f
uel tank left to avoid running out of
fuel. CAUTION
● Alw a

ys pay attention to any lit control
lamps and to the corresponding descriptions and instructions to avoid damage to the vehi-
cl
e.
● Nev

er run the fuel tank completely dry. An
irregu
lar fuel supply may lead to ignition
faults and unburnt fuel could enter the ex-
haust system. This could damage the catalyt-
ic converter. Note
The arrow next to the fuel pump symbol on
the ins trument

panel ››› Fig. 163 indicates the
side of the vehicle on which the fuel tank flap
is located. 182

Br ak
e fluid s

pecifications
SEAT have developed a special brake fluid
optimised for the brake systems of their vehi-
cles. To ensure the optimum working of the
brake system, SEAT recommends the use of
brake fluid in accordance with the VW 501 14
standard. If this brake fluid is not available or
another brake fluid is used for different rea-
sons, use a brake fluid that complies with the
United States standard FMVSS 116 DOT 4 or
the German standard DIN ISO 4925 CLASS 4
››› .
Br ak
e fluid

s conforming to the standard
VW 501 14, fulfil the American requirements
of the FMVSS 116 DOT 4 standard and the
German DIN ISO 4925 CLASS 4 standard.
However, fluids that comply with the Ameri-
can FMVSS 116 DOT 4 standard or the Ger-
man DIN ISO 4925 CLASS 4 standard do not
necessarily comply with the VW 501 14
standard. Always check the information on
the brake fluid container and ensure that you
are using suitable brake fluid.
A suitable brake fluid can be obtained from
SEAT dealerships. Brake fluid level
The level

of the brake fluid should always be
between the MIN and MAX marks, or above
the MIN mark ››› .
It i
s

not always possible to check the level of
the brake fluid, as in some models the en-
gine components make it difficult to see the
brake fluid reservoir. If you cannot read the
exact brake fluid level, consult a specialist.
The brake fluid level drops slightly when the
vehicle is being used due to wear of the
brake pads and the automatic readjustment
of the brake.
Changing the brake fluid
The brake fluid should be changed in accord-
ance with the instructions given in the Main-
tenance Programme. Have the brake fluid
changed by a specialised workshop. SEAT
recommends taking your car in for technical
service. This means that only brake fluid
complying with the required specifications
will be used. WARNING
If the brake fluid level is low or unsuita-
bl e/o

ld brake fluid is used, the brake system
may fail or braking power may be reduced.
● Check the brake system and the brake fluid
level
regularly! ●
The brak e fluid shou

ld be changed regular-
ly in accordance with the instructions given
in the Maintenance Programme.
● Always ensure that you use suitable brake
fluid. Only u
sed brake fluid that conforms to
the VW 501 14 standard, FMVSS 116 DOT 4
standard or even the DIN ISO 4925 CLASS 4
standard. Other types of brake fluid could af-
fect brake operation and reduce braking pow-
er. Do not use a brake fluid if the container
does not specify compliance with the
VW 501 14, FMVSS 116 DOT 4 or
DIN ISO 4925 CLASS 4 standards.
● The replacement brake fluid must be new.
● Brake fluid should be stored in the closed
original
container in a safe place out of reach
of children. Risk of poisoning!
● If the brake fluid is left in the system for
too long and the br
akes are subjected to
heavy use, vapour bubbles may form in the
brake system. This would seriously affect the
efficiency of the brakes and the safety of the
vehicle. This may cause an accident. CAUTION
Brake fluid damages the vehicle paintwork.
Wipe off an

y brake fluid from the paintwork
immediately. For the sake of the environment
Brake fluid is an environmental pollutant.
Co l

lect any spilt service fluids and allow a
professional to dispose of them. 192

Introduction SEAT recommend that all work on tyres and
wheels
i

s carried out by a specialised work-
shop. These workshops have the necessary
special tools and replacement parts, trained
personnel and facilities for disposing of the
old tyres while respecting the environment.
SEAT recommends taking your car in for tech-
nical service. WARNING
The vehicle cannot be totally controlled or
brak ed if

the tyres (new or used) are worn or
damaged.
● Incorrect use of wheels and tyres could
make driv
ing more dangerous and result in
serious accidents and damage.
● All four wheels must be fitted with radial
tyre
s of the same type, size (rolling circumfer-
ence) and the same tread pattern.
● New tyres do not give maximum grip and
wil
l not have reached their maximum braking
capacity to start with, and therefore need
running in. To prevent accidents and major
damage, extreme caution should be taken for
the first 600 km. ●
Check ty

re pressures regularly and ensure
they are maintained at the pressures indica-
ted. If the tyre pressure is too low, they could
overheat, resulting in tread detachment or
even burst tyres.
● Never drive on damaged (punctured, cut,
crac
ked or dented) or worn tyres. Driving on
damaged or worn tyres could result in burst
tyres, serious accidents or damage. Worn or
damaged tyres must be replaced immediate-
ly.
● Never exceed the maximum permitted
speed or loa
ds specified for the type of tyre
fitted on your vehicle.
● The effectiveness of driver and brake assist
syst
ems also depends on the grip of the
tyres.
● If you notice unusual vibration or if the ve-
hicle p
ulls to one side when driving, stop the
car immediately and check the tyres and
wheels for damage.
● To minimise the risk of losing control of the
vehicl
e or causing a serious accident, never
undo the bolted joints of beadlock wheels.
● Never mount used tyres or wheels if you are
not sur
e of their previous history. They may
be damaged, although the damage is not im-
mediately visible.
● Old tyres, even if they have never been
used, ma
y lose air or burst unexpectedly
while driving, especially at high speeds, re-
sulting in serious accident and injury. If tyres
are over six years old, they should only be used in an emergency and with extreme cau-
tion.
Note
For technical reasons, it is not generally pos-
s ib l

e to use the wheels from other vehicles.
In some cases, this may also be true for the
same model of wheel. Please refer to the ve-
hicle documentation or ask at a technical
service. Handling tyres and wheels

tween the vehicle and the road. »

Wheels and tyres
WARNING
Aggressive fluids or substances could result
in v i
sible or invisible damage with the conse-
quent risks.
● Always ensure that tyres do not come into
contact
with chemical products, oil, grease,
fuel, brake fluid or other aggressive substan-
ces. WARNING
Old tyres, even if they have never been used,
ma y

lose air or burst unexpectedly while driv-
ing, resulting in serious accident or damage.
● If tyres are over six years old, they should
only be u
sed in an emergency and with ex-
treme caution. For the sake of the environment
Old tyres must be disposed of by qualified
personnel ac

cording to the laws in the coun-
try concerned. Wheels
The design of wheel bolts is matched to the
rims. If
diff
er

ent rims are fitted, the correct
wheel bolts with the right length and correct-
ly shaped bolt heads must be used. This en-
sures that wheels are fitted securely and that
the brake system functions correctly
››› page 71. For technical reasons, it is not generally pos-
sibl

e to use the wheels from other vehicles.
In some cases, this may also be true for the
same model of wheel.
The tyres and rims approved by SEAT are spe-
cially matched to the characteristics of the
vehicle and are critical to good road holding
and safe handling.
Note for Italy: A SEAT Service Centre should
be consulted whether different sized wheels
or tyres to those originally fitted by SEAT may
be fitted, as well as the combinations al-
lowed between the front axle (axle 1) and
back axle (axle 2).
Wheel bolts
Wheel bolts must be tightened to the correct
torque ››› page 71.
Beadlock wheel rims
Beadlock wheel rims have various compo-
nents. These are joined together by special
bolts using a special procedure. This ensures
good performance, a better seal, improved
safety and wheel run out. Therefore, worn
rims should always be replaced and must on-
ly be repaired in a specialised workshop.
SEAT recommends visiting a technical service
››› .Wheel rims with bolted trims
Wheel
rims
m
ay be fitted with interchangea-
ble trim parts which are attached to the rim
using self-locking bolts. Worn trims should
only be replaced at a specialised workshop.
SEAT recommends visiting a technical service
››› .
WARNING
The use of worn or damaged wheel rims could
mak e driv

ing more dangerous and result in
serious accidents and damage.
● Only wheel rims which have been approved
for use w
ith your vehicle should be used.
● Inspect wheel rims regularly for damage
and repl
ace as required. WARNING
If the bolted joints of wheel rims with bolted
ring trims ar

e not correctly tightened or loos-
ened, this could result in serious accident.
● Never loosen the bolted joints of wheel
rims with bo
lted ring trims.
● Any work relating to wheel rims with bolted
rims shoul
d be carried out at specialised
workshop. SEAT recommends taking your car
in for technical service. 199
