2011 Seat Ibiza ST fuel pressure

176Driving and the environment
engine gives you the benefit of improved fuel efficiency as well as maxi-
mum reliability and an enhanced resale value.
A badly serviced engine can consume up to 10% more fuel than necessary.
Avoid short journeys
To reduce the consumption and emission of polluting gases, the engine and
the exhaust filtration systems should reach the optimum service tempera-
ture.
With the engine cold, fuel consumption is proportionally higher. The engine
does not warm up and fuel consumption does not normalise until having
driven approximately four kilometres. This is why we recommend avoiding
short trips whenever possible.
Maintain the correct tyre pressures
Bear in mind that keeping the tyres at an adequate pressure saves fuel. If
the tyre pressure is just one bar too low, fuel consumption can increase by
as much as 5%. Due to the greater rolling resistance, under-inflation also
increases tyre wear and impairs handling.
The tyre pressures should always be checked when the tyres are cold.
Do not use winter tyres all year round as they increase fuel consumption by
up to 10%.
Avoid unnecessary weight
Every kilo of extra weight will put up the fuel consumption, so it is worth
checking the luggage compartment occasionally to make sure that no un-
necessary loads are being transported.
A roof rack is often left in place for the sake of convenience, even when it is
no longer needed. At a speed of 100-120 km/h your vehicle will use about
12% more fuel as a result of the extra wind resistance caused by the roof
rack even when it is not in use. Save electricity
The engine activates the alternator, which produces electricity. With the
need for electricity, fuel consumption is also increased. Because of this, al-
ways turn off electrical components when you do not need them. Examples
of components that use a lot of electricity are: the fan at high speeds, the
rear window heating or the seat heaters*.
Note
● If you vehicle has Start-Stop, it is not recommended to disconnect this
function.
● It is recommended to close the windows when driving at more than 60
km/h
● Do not drive with your foot resting on the clutch pedal, as the pressure
can make the plate spin, more fuel will be used and it can burn the clutch
plate lining, causing a serious fault.
● Do not hold the vehicle on a hill with the clutch, use the foot brake or
hand brake, using the latter to start. The fuel consumption will be lower and
you will prevent the clutch plate from being damaged.
● On descents, use the engine brake, changing to the gear that is more
suitable for the slope. The fuel consumption will be lower and the brakes
will not suffer. 
Environmental friendliness
Environmental protection is a top priority in the design, choice of materials
and production of your new Seat.
Design measures for economical recycling
● Joints and connections designed for easy dismantling
● Modular construction to facilitate dismantling 

Trailer towing
What do you need to bear in mind when towing a trailer?
Your vehicle may be used to tow a trailer when fitted with the correct equip-
ment.
If the car is supplied with a factory-fitted towing bracket it will already have
the necessary technical modifications and meet the statutory requirements
for towing a trailer. If you wish to retrofit a towing bracket, consult
⇒ page 191.
Connectors
Your vehicle is fitted with a 12-pin connector for the electrical connection
between the trailer and the vehicle.
If the trailer has a 7-pin plug you will need to use an adapter cable. This is
available in any SEAT dealer.
Trailer weight / drawbar load
Never exceed the authorised trailer weight. If you do not load the trailer up
to the maximum permitted trailer weight, you can then climb correspond-
ingly steeper slopes.
The maximum trailer weights listed are only applicable for altitudes up to
1000 m above sea level. With increasing altitude the engine power and
therefore the vehicle's climbing ability are impaired because of the reduced
air density. The maximum trailer weight has to be reduced accordingly. The
weight of the vehicle and trailer combination must be reduced by 10% for
every further 1000 m (or part thereof). The gross combination weight is the
actual weight of the laden vehicle plus the actual weight of the laden trailer.
When possible, operate the trailer with the maximum permitted drawbar
load on the ball joint of the towing bracket, but do not exceed the specified
limit. The figures for
trailer weights and drawbar loads that are given on the data
plate of the towing bracket are for certification purposes only. The correct
figures for your specific model, which may be lower than these figures for
the towing bracket, are given in the vehicle documents or in ⇒ chapter Tech-
nical Data.
Distributing the load
Distribute loads in the trailer so that heavy objects are as near to the axle as
possible. Loads carried in the trailer must be secured to prevent them mov-
ing.
Tyre pressure
Set tyre pressure to the maximum permissible pressure shown on the stick-
er on the inside of the fuel tank flap. Set the tyre pressure of the trailer tyres
in accordance with the trailer manufacturer's recommendations.
Exterior mirrors
Check whether you can see enough of the road behind the trailer with the
standard mirrors. If this is not the case, you should have additional mirrors
fitted. Both exterior mirrors should be mounted on hinged extension brack-
ets. Adjust the mirrors to give sufficient vision to the rear.
WARNING
Never transport people in a trailer. This could result in fatal accidents.
Note
● Towing a trailer places additional demands on the vehicle. We recom-
mend additional services between the normal inspection intervals if the ve-
hicle is used frequently for towing a trailer.
● Find out whether special regulations apply to towing a trailer in your
country. 

Checking and refilling levels
Note
The four most common types of adapter in Europe are the ACME adapter 1,
the Dish Coupling adapter 2, the bayonet adapter 3 and the EURO adapt-
er 4. On the whole, we recommend you carry all four adapters in your vehi-
cle, as some countries use more than one type of filling system. The intro-
duction of a single system (Euronozzle) throughout Europe is being studied. 
LPG fuel
LPG is an alternative vehicle fuel and is a blend of propane and butane.
The success of LPG is due to the strict regulations concerning exhaust gas
emissions. Compared to other fossil fuels, LPG is characterised by its re-
duced emissions.
LPG quality and consumption
Quality requirements for LPG are regulated for all Europe in DIN EN 589 and
permit the use of LPG throughout Europe.
A difference is drawn between winter gas and summer gas. Winter gas has a
higher proportion of propane gas. As a result, the driving range of winter
gas may be lower (due to increased consumption) than that of summer gas.
LPG supplier network
The number of LPG pumps is constantly increasing.
Lists of existing LPG pumps may be found on Internet. 
LPG safety
A series of collision tests performed on this vehicle while running with LPG
have confirmed its high level of safety. The safety of the LPG system guarantees operation without risk. The follow-
ing safety measures have been adopted:
●
The LPG tank has a solenoid valve which closes automatically when the
engine is switched off (ignition off) or when running on petrol.
● A solenoid type main valve disconnects the supply of gas to the engine
compartment when the engine is switched off or running on petrol.
● A safety valve in the LPG tank with pipes to the outside prevents the gas
from entering the vehicle interior.
● All anchorage points and materials have been designed to ensure the
maximum possible levels of safety.
The condition of the LPG system should be checked regularly to guarantee
safe driving conditions ⇒ 
. These checks are included in the Maintenance
Programme.
WARNING
● If there is a smell of gas or a suspected leak, stop the vehicle immedi-
ately and switch off the ignition. Open the doors to ventilate the vehicle.
Do not carry on driving! Take the vehicle to a specialised workshop and
have the fault repaired.
● Immediately extinguish any cigarettes and remove from the vehicle
any objects which might produce a spark or cause a fire, and switch off
immediately if gas is smelt or a leak is detected.
● LPG tanks are subject to pressure and must be checked regularly. The
owner of the vehicle must check that these services are performed cor-
rectly.
● When parking the vehicle in a closed area (for example in a garage),
make sure that there is adequate ventilation, either natural or mechani-
cal, to neutralise the LPG in the event of a leak.
Note
For any fault in the LPG system, please refer to the SEAT web page, which
lists the workshops authorised to repair these faults. 

216Checking and refilling levels
Checking tyre pressure
The correct tyre pressure can be seen on the sticker on the
inside of the tank flap.
1. Read the required tyre inflation pressure from the sticker. The values refer to Summer tyres.
2. The tyre pressures should only be checked when the tyres are cold. The slightly raised pressures of warm tyres must not be re-
duced.
3. Adjust the tyre pressure to the load you are carrying.
Tyre pressure
The correct tyre pressure is especially important at high speeds. The pres-
sure should therefore be checked at least once a month and before starting
a journey.
WARNING
A tyre can easily burst if the pressure is too low, causing an accident!
● At continuously high speeds, a tyre with insufficient pressure flexes
more. In this way it becomes too hot, and this can cause tread separation
and tyre blow-out. Always observe the recommended tyre pressures.
● If the tyre pressure is too low or too high, the tyres will wear prema-
turely and the vehicle will not handle well. Risk of accident!
For the sake of the environment
Under-inflated tyres will increase fuel consumption. Tyre service life
The service life of tyres is dependent on tyre pressure, driv-
ing style and fitting.

Checking and refilling levels
Wear indicators
The original tyres on your vehicle have 1.6 mm high “tread wear indicators”
⇒ fig. 142, running across the tread. Depending on the make, there will be
6 to 8 of them evenly spaced around the tyre. Markings on the tyre sidewall
(for instance the letters “TWI” or other symbols) indicate the positions of
the tread wear indicators. The minimum tread depth required by law is
1.6 mm (measured in the tread grooves next to the tread wear indicators).
Worn tyres must be replaced. Different figures may apply in export countries
⇒ 
.
Tyre pressure
Incorrect tyre pressure causes premature wear and could cause tyre blow-
out. For this reason, the tyre pressure should be checked at least once per
month ⇒ page 216.
Driving style
Fast cornering, heavy acceleration and hard braking all increase tyre wear.
Changing wheels around
If the front tyres are worn considerably more than the rear ones it is advisa-
ble to change them around as shown ⇒ fig. 143. All the tyres will then last
for about the same time.
Wheel balance
The wheels on new vehicles are balanced. However, various factors encoun-
tered in normal driving can cause them to become unbalanced, which re-
sults in steering vibration.
Unbalanced wheels should be rebalanced, as they otherwise cause exces-
sive wear on steering, suspension and tyres. A wheel must also be reba-
lanced when a new tyre is fitted.
Incorrect wheel alignment
Incorrect wheel alignment causes excessive tyre wear, impairing the safety
of the vehicle. If tyres show excessive wear, you should have the wheel
alignment checked by an Authorised Service Centre.
WARNING
There is a serious danger of accidents if a tyre bursts during driving!
● The tyres must be replaced at the latest when the tread wear indica-
tors are worn ⇒ page 217. Failure to do so could result in an accident.
Worn tyres do not grip well at high speeds on wet roads. There is also a
greater risk of aquaplaning.
● At continuously high speeds, a tyre with insufficient pressure flexes
more. This causes it to overheat. This can cause tread separation and tyre
blow-out. Risk of accident. Always observe the recommended tyre pres-
sures.
● If tyres show excessive wear, you should have the running gear
checked by an Authorised Service Centre.
● Keep chemicals such as oil, fuel and brake fluid away from tyres.
● Damaged wheels and tyres must be replaced immediately!
For the sake of the environment
Under-inflated tyres will increase fuel consumption. 
New tyres and wheels
New tyres and wheels have to be run in.
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 characteris-
tics of the vehicle and make a major contribution to good road holding and
safe handling ⇒ 
.
Tyres should be replaced at least in pairs and not individually (i.e. both front
tyres or both rear tyres together). A knowledge of tyre designations makes it
easier to choose the correct tyres. Radial tyres have the tyre designations
marked on the sidewall, for example: 
