ed on, signalling that the function is being
verified. They will switch off after a few sec-
onds.
In natural gas engines
The warning lamp  lights up when both fuel
type

s (petrol and natural gas) have reached
reserve level.
The warning lamp  lights up when the vehi-
cl

e 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-
sult in the vehicle breaking down in traffic
and a serious accident.
● If the fuel level is too low then the fuel sup-
ply to 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 fuel tank left to avoid running out of
fuel. CAUTION
● Always pay attention to any lit control
lamps and to the corresponding descriptions and instructions to avoid damage to the vehi-
cle.
● Never run the fuel tank completely dry. An
irregular 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

ed to the holder Before refuelling, always turn off the engine,
the ignition, mobile telephones, auxiliary
heating and keep them off during refuelling.
Opening the fuel tank cap
● The tank flap is at the rear of the vehicle on
the right.
● Pull the rear zone of the fuel tank flap to
open.
● Unfold the key shaft if necessary
››› page 43 .
● Inser
t the vehicle key into the lock cylinder
of the fuel tank plug and turn the key in an
anticlockwise direction.
● Take out the fuel tank plug by turning it in
an anticlockwise direction and rest it on the
upper part of the fuel tank flap ››› Fig. 103. Ref
uelling
The correct petrol type for the vehicle is loca-
ted on a sticker inside the fuel tank flap
››› page 137.
● If the aut

omatic filler nozzle is operated
correctly, it will switch itself off as soon as
the fuel tank is full ››› .
● Do not continue to refuel if it is turned off!
Otherwise, this will fill the expansion cham-
ber and fuel may leak out if the ambient con-
ditions are warm.
Closing the fuel tank cap
● Screw on the fuel tank filler plug in a clock-
wise direction until it is fully inserted with a
click.
● Insert the vehicle key into the lock cylinder
of the fuel tank plug, turn the key in a clock-
wise direction and remove the key.
● Press the tank flap until you hear it click in-
to place. The tank flap must be flush with the
body contour. WARNING
Do not continue refilling once the fuel nozzle
has switched itself off. The fuel tank may be
filled too much. As a result, fuel may spurt
out and spill. This could lead to a fire, explo-
sion and severe injuries. CAUTION
● Always remove any fuel spilled anywhere
on the vehicle to avoid damage to the wheel
housing, the tyre and vehicle paintwork. For the sake of the environment
Fuels can contaminate the environment. Col-
lect any spilt service fluids and allow a pro-
fessional to dispose of them. Refuelling with natural gas

Checking and refilling levels
The vehicle is only prepared for refuelling
with Compressed Natural Gas (CNG) ››› . Re-
fuelling with another type of natural gas is
not allowed, e.g. Liquefied Nature Gas (LNG)
or hydromethane.
Opening the fuel tank cap
The natural gas filler mouth is behind the fuel
tank cap, next to the petrol filler mouth.
● Unlock the vehicle with the key or with the
central locking button  situated on the driv-
er door ›
›
› page 48.
● Press on the rear area of the flap and open
it.
Refuelling
Problem:
If the ambient temperature is very
high, the natural gas pump protection
against overheating disconnects this auto-
matically.
● Remove the plug from the gas filler mouth
››› Fig. 104
1 .
● Connect the pump filling nozzle to the gas
filler mouth.
● The fuel tank will be full when the pump
c ompr

essor automatically cuts the supply.
● If you wish to finish refuelling in advance,
press the button on the pump to stop the
flow. Closing the fuel tank cap
●
Check that the gas filler mouth retainer 2 is not trapped with the filler nozzle. If neces-
sary, place it in the filler mouth again.
●
Insert the plug in the filler mouth.
● Close the tank flap. Make sure you hear it
click into place. WARNING
Natural gas is a highly explosive, easily flam-
mable substance. Incorrect handling of the
natural gas can cause accidents serious
burns and other injuries.
● Before 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
natural 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 filling 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 indicate the presence of a fault in
the system.
● The vehicle natural gas system is prepared
both for refuelling with a small compressor
(slow refuel) and a large compressor (fast re-
fuel) in natural gas service stations. Bonnet

Wheels and tyres
Note
For technical reasons, it is not generally pos-
sible 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. About your tyres and wheels
Fig. 114
Diagram for changing wheels The tyres of a vehicle are the components
which are subjected to most stress and are
the most underestimated. Tyres are very im-
portant, as the support offered by their nar-
row surface is the only point of contact be-
tween the vehicle and the road.
The service life of tyres is dependent on tyre
pressure, 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
obstacle, drive very slowly and as near as
possible at a right angle to the kerb.
● Inspect the tyres regularly for damage
(punctures, cuts, cracks, dents).
● Remove any foreign bodies found on the
outside of the tyre tread and ensure that they
have not passed through the wall of the tyre
››› page 163 .
● In a d
dition, the instructions for tyre control
systems should always be observed.
● Replace damaged or worn tyres as soon as
possible ››› page 163.
● Re

gularly check tyres for non-visible dam-
age ››› page 163
.
● Never exceed the maximum permitted
speed or loads specified for the type of tyre
fitted on your vehicle ››› page 167.
● Do not allow tyres (including the spare
wheel) to come into contact with aggressive
substances, grease, oil, fuel or brake fluid
››› .●
Lost valve caps should be replaced imme-
diately.
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 167. 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. 114 . The useful life of all the tyres will
then be about the s

ame time.
SEAT recommends you take the vehicle to a
specialised workshop to have the tyres
changed. »

Advice
Tyres that are over 6 years old
Tyres 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 date of manufacture, part of the tyre
identification number (TIN), indicates the age
of the tyre ( ) ››› page 167 .
St orin
g 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
mount

ed 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. WARNING
Aggressive fluids or substances could result
in visible 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,
may 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 used in an emergency and with ex-
treme caution. For the sake of the environment
Old tyres must be disposed of by qualified
personnel according to the laws in the coun-
try concerned. Wheel rims
The design of wheel bolts is matched to the
rims. If different 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 174 . F
or t
echnical reasons, it is not generally pos-
sible 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 174
.
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

CAUTION
● Take care 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. Tread depth and wear indicators
Fig. 116
Tyre tread: tread wear indicators Tread depth
Certain driving conditions require a deeper
tread, as well as needing the tread to be ap- proximately the same on the front and rear
tyres. This is particularly important when
driving in winter, in cold temperatures and on
wet roads
››› .
The minimum tread depth required by law in
the majority of cases is 1.6 mm, measured in
the tread grooves next to the tread wear indi-
cators. Observe legal requirements in each
country.
The performance of winter tyres is much re-
duced when the tread has worn to 4 mm.
The tread depth of new tyres may vary, ac-
cording to the type and make of tyre and the
tread pattern.
Wear indicators on the tyre
The original tyres on your vehicle have
1.6 mm high ››› Fig. 116 tread wear indicators
ru nnin
g across the tread. A number of these
indicators are equally spaced around the tyre
tread. Certain marks on the tyre walls (e.g.
the letters “TWI” or other symbols) indicate
the position of the wear indicators.
Tread wear indicators indicate if a tyre is
worn. They must always be replaced before
the tyre tread has worn to the level of the in-
dicator. WARNING
Driving with worn tyres is dangerous, and
may lead to loss of control of the vehicle with
serious consequences.
● Tyres must be replaced before the wear in-
dicators are at the same level as the tread
pattern.
● Worn tyres have significantly reduced grip,
especially on wet surfaces, increasing the
risk of “aquaplaning”.
● Worn tyres make control of the vehicle
more difficult in normal or difficult driving
conditions, increasing the braking distance
and the risk of skidding. Damaged tyres
Damage to wheels and tyres is often not im-
mediately visible. If you notice unusual
vibra-
tion or the car
pulling to one side
, this may
indicate that one of the tyres is damaged
››› .
● Slow down immediately if you think you
have a damaged wheel.
● Check the wheels and tyres for damage.
● If tyres are worn, stop driving and seek
qualified assistance.
● If there is no visible exterior damage, drive
slowly and carefully to the nearest special-
ised workshop and have the vehicle checked. »

Foreign bodies in the tyre
● Do not remove foreign bodies if they have
penetrated through the tyre wall!
● You should obtain professional assistance
immediately.
Wear of tyres
The wear of tyres depends on a number of
factors, for example:
● Driving style.
● Unbalanced wheels.
● Running gear settings.
Driving style : Driving round bends quickly or
sudden acceleration or braking speed accel-
erates tyre wear. When the driving style is
normal, if the tyres wear too quickly, have the
running gear settings checked at a special-
ised workshop.
Wheel run-out : The wheels on new vehicles
ar e b
alanced. However, certain circumstan-
ces may lead to imbalance (run-out), which is
detected as vibrations in the steering wheel.
Run-out leads to wear of the steering and
suspension. In the event of run out, the
wheels should be balanced again. When a
new wheel is fitted, it should be balanced
again.
Running gear settings : an incorrectly posi-
tioned running gear increases the wear of
tyres and affects your safety while driving. If tyres wear too quickly, have the wheel align-
ment checked at a specialised workshop. WARNING
If you notice unusual vibration or the car pulls
to one side while driving, this may indicate
that one of the tyres is damaged.
● Reduce speed immediately and stop, while
observing the highway code.
● Check the wheels and tyres for damage.
● Never carry on driving on worn tyres or
wheels. Request qualified assistance immedi-
ately.
● If there is no visible exterior damage, drive
slowly and carefully to the nearest special-
ised workshop and have the vehicle checked. Tyre monitoring system* 
Fig. 117
Centre console: tyre monitor system
button The tyre control lamp compares wheel revolu-
tions and with it, the wheel diameter of each
wheel using the ESC. If the diameter of a
wheel changes, the tyre control lamp

lights up. The wheel diameter changes when:
● Tyre pressure is insufficient.
● The tyre structure is damaged.
● The vehicle is unbalanced because of a
load.
● The wheels of one axle are under more
pressure (for example, driving with a trailer or
on steep slopes).
● The vehicle is fitted with snow chains.
● The temporary spare wheel is fitted.
● The wheel on one axle is changed.
Tyre pressure adjustment
On adjusting tyre pressure or changing one
or more wheels, the ››› Fig. 117 button must
be k ept
pressed down, with the ignition on,
until an acoustic signal is heard.
If the wheels are under excessive load (for ex-
ample, driving with a trailer or heavy load),
the tyre pressure must be increased to the
recommended value for a full load (see the
sticker on the inside of the fuel flap). If the
tyre monitor system button is pressed down,
the new tyre pressures are confirmed.

Advice
drawing attention to your vehicle. This meth-
od must comply with traffic legislation. WARNING
A faulty vehicle in traffic represents a risk of
accident for the driver and for other road
users.
● Stop the vehicle safely as soon as possible.
Park the vehicle a safe distance from sur-
rounding traffic to lock all the doors in case of
an emergency. Turn on the hazard warning
lights to warn other road users.
● Never leave children or disabled people
alone in the vehicle if the doors are to be
locked. In case of an emergency, passengers
will be trapped inside the vehicle. Individuals
locked in the vehicle can be exposed to very
high or very low temperatures. WARNING
The components of the exhaust system reach
very high temperatures. This could cause a
fire and considerable damage.
● Always park your vehicle so that no part of
the exhaust system can come in contact with
flammable materials (such as dried grass or
fuel). Note
● The vehicle battery will discharge and run
down if the hazard warning lights remain on
for too long (even with the ignition turned
off). ●
For some vehicles, the brake lights will
blink when braking suddenly at speeds of ap-
proximately 80 km/h (50 mph) to alert vehi-
cles to the rear. If braking continues, the haz-
ard warning lights system will automatically
be turned on at a speed of less than approxi-
mately 10 km/h (6 mph). The brake lights re-
main lit. Upon accelerating, the hazard warn-
ing lights will be automatically turned off. Vehicle tool kit*
Introduction When securing the vehicle in case of a break-
down, please note the legal requirements for
each country.
Vehicle tool kit
For vehicles with a factory-fitted spare wheel
or temporary spare wheel, in addition to win-
ter wheels, the luggage compartment may
contain additional vehicle tools
