Seats and storage compartmentsThe importance of correct seat adjustmentProper seat adjustment optimises the level of protection
offered by seat belts and airbags.Your vehicle has five seats, two in the front and three in the rear. Each seat is
equipped with a three-point seat belt.
The driver seat and the front passenger seat can be adjusted in many ways to
suit the physical requirements of the vehicle occupants. The correct seat
position is very important for:•a fast and easy operation of all controls on the instrument panel,•a relaxed posture which does not cause drowsiness,•a safe driving ⇒ page 7,•ensuring that the seat belts and airbag system provide maximum protec-
tion ⇒page 19.WARNING
•If the driver and passengers assume improper sitting positions, they
may sustain critical injuries.•More people than available seats must never be transported in your
vehicle.•Every passenger in the vehicle must properly fasten and wear the seat
belt belonging to his or her seat. Chil dren must be protected with an appro-
priate child restraint system ⇒page 46, “Child safety”.•The front seats and all head restraints must always be adjusted to body
size and the seat belt must always be properly adjusted to provide you and
your passengers with optimum protection.
•Always keep your feet on the footwell when the vehicle is moving; never
rest them on the dash panel, out of the window or on the seat. This is also
applied to passengers. An incorrect sitting position exposes you to an
increased risk of injury in case of a sudden braking or an accident. If the
airbag is triggered, you could sustain severe injuries due to an incorrect
sitting position.•It is important for the driver and front passenger to keep a distance of
at least 25 cm from the steering wheel or dash panel. Failure to respect the
minimum distance means that the airbag will not protect you. Risk of fatal
injury. The distance between the driver and the steering wheel or between
the front passenger and the dash panel should always be as great as
possible.•Adjust the driver or front passenger seat only when the vehicle is
stationary. Otherwise, your seat could move unexpectedly while the
vehicle is moving. This could increase the risk of an accident and therefore,
injury. In addition, while adjusting your seat, you will assume an incorrect
sitting position. Risk of fatal accidents.•Special guidelines apply to installing a child seat on the front
passenger seat. When installing a child seat, please observe the warnings
described in ⇒page 46, “Child safety”.WARNING (continued)

Running on petrol
Run the engine with petrol for short journeys at regular intervals to avoid
problems in the petrol system.
WARNING
LPG is a highly explosive and inflammable substance. It may cause severe
burns and other injury.•Due care must be taken to avoid any risk of fire or explosion.•When parking the vehicle in a closed area (for example in a garage),
make sure that there is adequate ventilation, either natural or mechanical,
to neutralise the LPG in the event of a leak.Note
•If frequent short journeys are made, especially when the outside temper-
ature is low, the vehicle will tend to run on petrol more often than on LPG.
Therefore, the petrol tank may empty before the LPG tank.•The notification LPG mode not possible may be displayed.Start-Stop function*Description and operationThe Start-Stop function stops the engine when the vehicle is
stopped and starts it automatically when required. – When the vehicle is stopped, put it in neutral and release the

176HandbrakeUsing the handbrake
The handbrake should be applied firmly to prevent the
vehicle from accidentally rolling away.Always apply the handbrake when you leave your vehicle and when
you park.
Applying the handbrake
– Pull the handbrake lever up firmly ⇒fig. 129 .
Releasing the handbrake
– Pull the lever up slightly and press the release knob in the direc- tion of the arrow ⇒fig. 129 and guide the handbrake lever down
fully ⇒ .
Always apply the handbrake as far as it will go in order to prevent you from
driving with the handbrake applied by mistake ⇒.
The handbrake warning lamp
H lights up when the handbrake is applied
and the ignition switched on. The warning turns off when the handbrake is
released.
If you drive faster than 6 km/h with the handbrake on, the following
message* will appear on the instrument panel display: HANDBRAKE ON. Yo u
will also hear an acoustic warning signal.
WARNING
•Never use the handbrake to stop the vehicle when it is in motion. The
braking distance is considerably longer, because braking is only applied to
the rear wheels. Risk of accident!•If it is only partially released, this will cause rear brakes overheating,
which can impair the function of the brake system and could lead to an acci-
dent. This also causes premature wear on the rear brake pads.Caution
Always apply the handbrake before you leave the vehicle. The 1st gear should
also be selected.Parking
The handbrake should always be firmly applied when the
vehicle is parked.Always note the following points when parking the vehicle:
– Use the brake pedal to stop the vehicle.

Driving and the environment
196reduce fuel consumption by 10-15%. Some tips on how to help you reduce
pollution while saving money are listed below.
Drive anticipating the traffic situation
A vehicle uses most fuel when accelerating. When you anticipate the situa-
tion, you have to brake less often and, thus, accelerate less. If it is possible,
let the vehicle roll with a gear engaged, for example, if you see a red light
ahead. The braking effect achieved in this way helps to reduce the wear of
brakes and tyres; emissions and fuel consumption are reduced to zero
(disconnection due to inertia).
Change gear early to save energy
An effective way of saving fuel is to change up quickly through the gears.
Running the engine at high rpm in the lower gears uses an unnecessary
amount of fuel.
Manual gearbox: Change from first to second gear as quickly as possible. We
recommend that, whenever possible, you change to a higher gear upon
reaching 2000 rpm. Follow the recommended gear indication that appears on
the instrument panel ⇒page 62.
Avoid driving at high speed
We advise you not to drive at the top speed permitted by the vehicle. Fuel
consumption, exhaust emissions and noise levels all increase very rapidly at
higher speeds. Driving at moderate speeds will help to save fuel.
Avoid idling
It is worthwhile switching off the engine when waiting in a traffic jam, at level
crossings or at traffic lights with a long red phase. The fuel saved after only
30 - 40seconds is greater than the amount of fuel needed to restart the
engine.
The engine takes a long time to warm up when it is idling. Mechanical wear
and pollutant emissions are also especially high during this initial warm-up
phase. It is therefore best to drive off immediately after starting the engine.
Avoid running the engine at high speed. Periodic maintenance
Periodic maintenance work guarantees that, before beginning a journey, you
will not consume more than the required amount of fuel. A well-serviced
engine gives you the benefit of
improved fuel efficiency as well as maximum
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 unnec-
essary 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 100-120km/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.

2. The tyre pressures should only be checked when the tyres are cold. The slightly raised pressu res of warm tyres must not be
reduced.
3. Adjust the tyre pressure to the load you are carrying.Tyre pressure
The correct tyre pressure is especially important at high speeds. The pressure
should therefore be checked at least once a month and before starting a
journey.
The sticker with the tyre pressure values can be found on the inside of the
tank flap. The tyre pressure values given are for cold tyres. Do not reduce the
slightly raised pressures of warm tyres ⇒.
WARNING
•Check the tyre pressure at least once per month. Checking the tyre
pressure is very important. If the tyre pressure is too high or too low, there
is an increased danger of accidents - particularly at high speeds.•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 pressure monitoring
The tyre pressure monitoring system constantly checks the
pressure of the tyres.The system uses the speed sensors of the ABS wheels. It operates by
analysing the speed and frequency spectrum of each wheel.
For optimum performance, use genuine SEAT tyres. In addition, check and
adjust tyre pressures regularly.
Whenever the tyre pressures are changed or one or more tyres are changed,
the system should be Reset by pressing the SET switch on the centre console.
The system warns the driver in the event of a loss of pressure by means of
symbols and messages in the instrument panel display. The system uses ESP
⇒ page 187.
Note that tyre pressure also depends on tyre temperature. Tyre pressure
increases about 0.1 bar for each 10 °C in tyre temperature increase. The tyre
heats up while the vehicle is being driven and the tyre pressure will rise
accordingly. For this reason, you should only adjust the tyre pressures when
they are cold (i.e. approximately at ambient temperature).
To ensure that the tyre pressure monitoring system works reliably, you should
check and, if necessary, adjust the tyre pressures at regular intervals and
store the correct pressures (reference values) in the system.
A tyre pressure information label is attached to the inside of the fuel tank flap.
WARNING
•Never adjust tyre pressure when the tyres are hot. This may damage or
even burst the tyres. Risk of accident!•An insufficiently inflated tyre flexes a lot more at high speeds and
causes significant heating of the tyre. Under these conditions, the tyre
bead may be released or the tyre may burst. Risk of accident!
