Operation
For the sake of the environment
Do not warm-up the engine by running the
engine with the vehicle stationary. Start off
immediately, driving gently. This helps the
engine reach operating temperature faster
and reduces emissions. Starting diesel engines
The engine can only be started using a genu-
ine SEAT key with its correct code.
– Move the gearbox lever to the neutral posi-
tion and depress the clutch pedal thor-
oughly and hold it in this position for the
starter to turn the engine on.
– Turn the ignition key to position ›››
Fig. 122
1 . The warning lamp
 will light for en-
gine pre-heating.
– When the lamp turns off, turn the ignition
key to position 2 to start the engine. Do
not press the accelerator.
– Release the ignition key as soon as the en-
gine starts. The starter motor should not
turn at the same time.
When starting a cold engine, it may be a little
noisy for the first few seconds until oil pres-
sure has built up in the hydraulic valve com-
pensators. This is quite normal, and no cause
for concern. If there are problems starting the engine, see
the

Glo w p
lug system for the diesel engine
To avoid unnecessary discharging of the bat-
tery, do not use any other major electrical
equipment while the glow plugs are pre-heat-
ing.
Start the engine as soon as the glow plug
warning lamp ››› page 41 goes out.
Starting a diesel engine after the fuel tank
has been completely run dry
If the fuel tank has been completely run dry,
it may take longer than normal (up to one mi-
nute) to start a diesel engine after refuelling.
This is because the fuel system must elimi-
nate air first. WARNING
● Never start or run the engine in unventila-
ted or closed rooms. The exhaust gases con-
tain carbon monoxide, an odourless and col-
ourless poisonous gas. Risk of fatal acci-
dents. Carbon monoxide can cause loss of
consciousness and result in death.
● Never leave the vehicle unattended if the
engine is running.
● Never use “cold start sprays”, they could
explode or cause the engine to run at high
revs. Risk of injury. CAUTION
● When the engine is cold, you should avoid
high engine speeds, driving at full throttle
and over-loading the engine. Risk of engine
damage.
● The vehicle should not be pushed or towed
more than 50 metres to start the engine. Un-
burnt fuel could enter the catalytic converter
and damage it.
● Before attempting to push-start or tow a ve-
hicle in order to start it, you should first try to
start it using the battery of another vehicle.
Note and follow the instructions in
››› page 189, Jump-starting. For the sake of the environment
Do not warm-up the engine by running the
engine with the vehicle stationary. You
should drive off as soon as you start the en-

Operation
WARNING
● Apply the brakes heavily to clean the brake
system only in a suitable traffic situation. Do
not put other road users in danger: there is
risk of causing an accident.
● Ensure the vehicle does not move while in
neutral, when the engine is stopped. Failure
to follow this instruction could result in an
accident.
● If the brake fluid loses its viscosity and is
subjected to heavy use, vapour bubbles can
form in the brake system. This reduces the ef-
ficiency of the brakes.
● If a brake system circuit fails, the braking
distance will be increased considerably. Con-
tact a specialised workshop immediately and
avoid unnecessary journeys. CAUTION
● Never let the brakes “drag” by leaving your
foot on the pedal when it is not necessary to
brake. This overheats the brakes, resulting in
longer stopping distances and greater wear.
● Before driving down a long, steep gradient,
it is advisable to reduce speed and select a
lower gear. This makes use of engine braking
and relieves the brakes. If you still have to
use the brakes, it is better to brake firmly at
intervals than to apply the brakes continu-
ously. Note
● If the brake servo is out of action, for exam-
ple when the car is being towed, you will
have to press the brake pedal considerably
harder than normal to make up for the lack of
servo assistance.
● If you wish to equip the vehicle with acces-
sories such as a front spoiler or wheel covers,
it is important that the flow of air to the front
wheels is not obstructed, otherwise the
brakes can overheat. Before purchasing ac-
cessories please observe the relevant instruc-
tions ››› page 147, Technical modifications . Operating the handbrake
Fig. 123
Handbrake between the front seats. 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. 123 .
R el
easing the handbrake
– Pull the lever up slightly and press the re-
lease knob in the direction of the arrow
››› Fig. 123 and guide the handbrake lever
down f

ully ››› .
Always pull the handbrake all the way up, so
there is less risk of driving off with it still en-
gaged ››› .
The handbrake warning lamp  lights up
when the handbrake is applied and the igni-
tion switched on. The warning lamp turns off
when the handbrake is released.
If you drive faster than 6 km/h (4 mph) with
the handbrake on, the following message*
will appear on the instrument panel: HAND-
BRAKE ON. You will also hear an audible
warning. WARNING
● Never use the handbrake to stop the vehi-
cle when it is in motion. The braking distance
is considerably longer, because braking is
only applied to the rear wheels. Risk of acci-
dent! 124

Driving
●
If the handbrake is only partially released,
this will cause the rear brakes to overheat,
which can impair the function of the brake
system and could lead to an accident. This al-
so causes premature wear on the rear brake
pads. CAUTION
Always apply the handbrake before you leave
the vehicle. Put it in 1st gear as well. Parking
The handbrake should always be firmly ap-
plied when the vehicle is parked.
Always note the following points when park-
ing the vehicle:
– Use the brake pedal to stop the vehicle.
– Apply the handbrake.
– Put it in 1st gear.
– Switch the engine off and remove the key
from the ignition. Turn the steering wheel
slightly to engage the steering lock.
– Always take you keys with you when you
leave the vehicle ››› .Additional notes on parking the vehicle on
gradients:
Turn the steering wheel so that the vehicle
rolls against the kerb if it started to roll.
●
If the vehicle is parked facing downhill,
turn the front wheels so that they point to-
wards the kerb .
● If the vehicle is parked facing uphill, turn
the fr ont
wheels so that they point away from
the kerb
.
● Secure the vehicle as usual by applying the
handbrake firmly and putting it in 1st gear. WARNING
● Take measures to reduce the risk of injury
when you leave your vehicle unattended.
● Never park where the hot exhaust system
could ignite inflammable materials, such as
dry grass, low bushes, spilt fuel etc.
● Never allow vehicle occupants to remain in
the vehicle when it is locked. They would be
unable to open the vehicle from the inside,
and could become trapped in the vehicle in
an emergency. In the event of an emergency,
locked doors will delay assistance to vehicle
occupants.
● Never leave children alone in the vehicle.
They could set the vehicle in motion, for ex-
ample, by releasing the handbrake or the
gearbox lever. ●
Depending on weather conditions, it may
become extremely hot or cold inside the vehi-
cle. This can be fatal. Hill driving assistant*
This function is only included in vehicles with
ESC.
The hill driving assistant helps the driver to
move off and upward on a hill without rolling
backward.
The system maintains brake pressure for ap-
proximately 2 seconds after the driver takes
his foot off the brake pedal to prevent the ve-
hicle from rolling backward when starting off.
During these 2 seconds, the driver has
enough time to release the clutch pedal and
accelerate without the vehicle moving and
without having to use the handbrake, making
starting off easier, more comfortable and saf-
er.
These are the basic operation conditions:
● being on a ramp or hill/slope,
● closed doors,
● vehicle completely stationary,
● engine running and foot on the brake,
● besides having a gear engaged or being in
neutral for manual gear change and with the
selector lever at position S,
D
or R for an au-
tomatic gearbox. »

Operation
This system is also active when reversing up-
hill. WARNING
● If you do not start the vehicle immediately
after taking your foot off the brake pedal, the
vehicle may start to roll back under certain
conditions. Depress the brake pedal or use
the hand brake immediately.
● If the engine stalls, depress the brake ped-
al or use the hand brake immediately.
● When following a line of traffic uphill, if you
want to prevent the vehicle from rolling back
accidentally when starting off, hold the brake
pedal down for a few seconds before starting
to move. Note
The official service or a specialist workshop
can tell you if your vehicle is equipped with
this system. Manual gearbox
Driving with a manual gearbox Fig. 124
Detailed view of the centre console:
gear shift pattern of a 5- or 6-speed manual
gearbox. Engaging the reverse gear
– The vehicle should be stationary with the
engine idling. Press the clutch down thor-
oughly.
– Place the gearbox lever into neutral and
push the lever downwards.
– Slide the gearbox lever to the left, and then
into the reverse position shown on the lev-
er.
The reverse gear can only be engaged when
the vehicle is stationary. When the engine is
running and before engaging this gear, wait
about 6 seconds with the clutch pressed down thoroughly in order to protect the gear-
box.
The reverse lights switch on when the reverse
gear is selected and the ignition is on.
WARNING
● When the engine is running, the vehicle
will start to move as soon as a gear is engag-
ed and the clutch released.
● Never select the reverse gear when the ve-
hicle is in motion. Risk of accident. Note
● Do not rest your hand on the gear lever
while driving. The pressure of your hand
could cause premature wear on the selector
forks in the gearbox.
● When changing gear, you should always
depress the clutch fully to avoid unnecessary
wear and damage.
● Do not “slip” the clutch to hold the vehicle
on a hill. This causes premature wear and
damage to the clutch.
● Do not leave your foot on the clutch pedal;
although the pressure may seem insignifi-
cant, it can cause the premature wear of the
clutch plate. Use the foot rest when you do
not need to change gear. 126

Stopping briefly – If stopping for a short time, keep the vehi-
cle stationary by pressing the foot brake
hard to prevent the vehicle moving back-
wards on a slope or “creeping” forwards,
e.g. at traffic lights. The selector lever does
not need to be put into the positions P or N
f or thi

s.
– Do not press the accelerator.
Parking
– Press and hold the brake pedal until the ve-
hicle comes to a standstill ››› .
– Apply the handbrake.
– By pressing the lock button down, move
the selector lever to P
and release the lock
b

utton.
Driving up and down hills
– Press the selector lever from position “D”
to the right into the tiptronic selector gate. –
Lightly press the selector lever back to
change down.
Holding the car on a hill – The brake must be always pressed down to
prevent the vehicle from “rolling back-
wards” ››› . Do not try to prevent the vehi-
cle from “rolling backwards” by increasing
the engine speed while a range of gears is
selected.
Starting the vehicle up hills
– Apply the handbrake.
– With a selected gear, accelerate slowly and
at the same time, release the handbrake.
The steeper the slope, the lower the needed
gear. This increases the braking effect of the
engine. For example, when driving down a
very steep slope in third gear. If the engine
brake effect is not enough, the vehicle will
speed up. The automatic gearbox automati-
cally changes up to prevent the engine over-
revving. Use the foot brake to reduce speed
and change into 3rd gear using Tiptronic*

Your vehicle has an automatic interlock
which prevents the selector lever from being
put into a position for driving forwards or in
reverse from positions P or N

When the warning lamp next to the selector
lever lights up, press the brake pedal. This is
necessary when the automatic gearbox selec-
tor lever is moved out of positions P or N
. A
text message or instructions to perform nec-
essary operations may appear on the instru-
ment panel. WARNING
● As a driver, you should never leave your ve-
hicle if the engine is running and a gear range
is engaged. If you have to leave your vehicle
while the engine is running, you must apply
the parking brake and put the selector lever
in position P.
● If the engine is running and if D or R is en-
gaged, you will need to hold the car on the
foot brake. The car will creep forward as the
power transmission is not fully interrupted
even when the engine is idling.
● Never accelerate when moving the selector
lever or you may cause an accident.
● Never move the selector lever to R or P
when driving. Risk of accident!
● Before driving down a long, steep slope, it
is advisable to reduce speed and change into
a lower gear. ●
If you stop the vehicle up hill, always hold
the foot brake strongly depressed down to
stop it from rolling back.
● Never allow the brake to rub and do not use
the brake pedal too often or for long periods.
Constant braking will cause the brakes to
overheat and will considerably reduce the
brake effect. This increases the braking dis-
tance and could cause the brake system to
fail.
● Never allow the car to roll down a gradient
with the gear in neutral N, or in selector lever
position D, even if the engine is not running. CAUTION
● If you stop the vehicle up hills, do not at-
tempt to stop it from rolling back by depress-
ing the accelerator when a gear has been se-
lected. Otherwise, the automatic gearbox
may overheat causing damage. Pull the hand-
brake up or fully depress the brake pedal to
prevent the vehicle from rolling away.
● If you allow the vehicle to roll when the en-
gine is not running, or with the selector lever
in position N, a lack of lubrication in the auto-
matic gearbox will damage it. Changing gear in Tiptronic mode*

General information about driving in
tiptronic mode
When accelerating, the automatic gearbox /
DSG automatic gearbox goes into a higher
gear a little before the engine reaches its
maximum permitted revolutions.
If a lower gear is selected, the automatic
gearbox / DSG automatic gearbox will only
change down when the engine cannot go
over its maximum permitted revolutions.
If “tiptronic” is selected whilst the vehicle is
in motion and the automatic gearbox / DSG
automatic gearbox is in third gear and selec- tor lever position D, “tiptronic” mode will
then also be in third gear.
Changing gears in the normal or sport
programme using the steering wheel paddle
levers
If the paddle levers
››› Fig. 129 are used in
the normal

or sport programme, the system
switches temporarily to “tiptronic” mode. To
exit “Tiptronic” mode again, press the right
paddle shifter +OFF toward the steering
wheel for approximately one second. You will
also leave “Tiptronic” mode if the paddle lev-
ers are not moved for a certain time. Note
● The gearbox controls on the steering wheel
can operate with the selector lever in any po-
sition and with the vehicle in motion. Kick-down feature
This feature allows maximum acceleration.
If you press the accelerator down thoroughly,
the gearbox automatically changes down, de-
pending on speed and engine speed, into a
lower gear to take full advantage of give the
vehicle maximum acceleration.
The gearbox does not change gear until the
engine reaches the maximum determined en-
gine speed for the gear. WARNING
You could lose control of the vehicle if you ac-
celerate on slippery road surfaces. Risk of se-
rious injury.
● Be particularly careful when using the kick-
down features on slippery road surfaces. With
a fast acceleration, the vehicle could lose
traction and skid.
● You should use the kick-down feature only
when traffic and weather conditions allow it
to be used safely. Run-in and economical driving
Running in a new engine The engine needs to be run in over the first
1,500 km.
Up to 1,000 kilometres
– Do not drive at speeds of more than 2/3
the maximum speed.
– Do not accelerate hard.
– Avoid high engine revolutions.
– Do not tow a trailer.
130

Driving
From 1,000 to 1,500 kilometres
– Speeds can be gradually increased to the
maximum road speed or maximum
permissible engine speed (rpm).
During its first few hours of running, the in-
ternal friction in the engine is greater than
later on, when all the moving parts have bed-
ded in. For the sake of the environment
If the engine is run in gently, its life will be in-
creased and its oil consumption reduced. Environmental friendliness
Environmental protection is a top priority in
the design, choice of materials and manufac-
ture of your new SEAT.
Constructive measures to encourage
recycling
● Joints and connections designed for easy
dismantling
● Modular construction to facilitate disman-
tling
● Increased use of single-grade materials.
● Plastic parts and elastomers are marked in
accordance with ISO 1043, ISO 11469 and
ISO 1629. Choice of materials
●
Use of recycled materials.
● Use of compatible plastics in the same part
if its components are not easily separated.
● Use of recycled materials and/or materials
originating from renewable sources.
● Reduction of volatile components, includ-
ing odour, in plastic materials.
● Use of CFC-free coolants.
Ban on heavy metals, with the exceptions
dictated by law (Annex II of ELV Directive
2000/53/EC): cadmium, lead, mercury, hexa-
v al
ent chromium.
Manufacturing methods
● Reduction of the quantity of thinner in the
protective wax for cavities.
● Use of plastic film as protection during ve-
hicle transport.
● Use of solvent-free adhesives.
● Use of CFC-free coolants in cooling sys-
tems.
● Recycling and energy recovery from resi-
dues (RDF).
● Improvement in the quality of waste water.
● Use of systems for the recovery of residual
heat (thermal recovery, enthalpy wheels,
etc.).
● Use of water-soluble paints. Catalytic converter To maintain the useful life of the catalytic
converter
– Use only unleaded petrol with petrol en-
gines, as lead damages the catalytic con-
verter.
– Do not let the fuel get too low in the tank.
– For engine oil changes, do not replenish
with too much engine oil ››› page 168, Top-
ping up engine oil .
– Never tow the vehicle to start it, use jump
leads if necessary ›››
page 189.
If you notice misfiring, uneven running or
loss of power when the vehicle is moving, re-
duce speed immediately and have the vehi-
cle inspected at the nearest specialised
workshop. In general, the exhaust warning
lamp will light up when any of the described
symptoms occur ›››
page 35 . If this happens,
u nb

urnt fuel can enter the exhaust system
and escape into the environment. The cata-
lytic converter can also be damaged by over-
heating. WARNING
The catalytic converter reaches very high
temperatures! Risk of fire!
● Never park where the catalytic converter
could come into contact with dry grass or
flammable materials under the vehicle. » 131

Safety

Operation
●
Do not apply additional underseal or anti-
corrosion coatings to the exhaust pipes, cata-
lytic converter or the heat shields on the ex-
haust system. These materials could catch
fire when the vehicle is being driven. CAUTION
Never run the fuel tank completely dry be-
cause the irregularity of the fuel supply may
cause ignition problems. This allows unburnt
fuel to enter the exhaust system, which could
cause overheating and damage the catalytic
converter. For the sake of the environment
Even when the emission control system is
working perfectly, there may be a smell of
sulphur from the exhaust gas under some
conditions. This depends on the sulphur con-
tent of the fuel used. Quite often the problem
can be solved by changing to another brand
of fuel. Diesel engine particulate filter*
Fig. 130
Vehicle data sticker on back cover of
the Maintenance Programme. Your vehicle is fitted with a DPF (Diesel partic-
ulate filter) if the vehicle data sticker (back
cover of the “Maintenance Programme)” lists
the PR code 7GG or 7MG
››› Fig. 130 .
The die sel
engine particulate filter eliminates
most of the soot from the exhaust gas sys-
tem. Under normal driving conditions, the fil-
ter cleans itself. If this is not possible (for ex-
ample, multiple short trips) the filter will be
obstructed by soot and  the diesel engine
particulate filter warning lamp will light up.
This does not represent a fault, it is a warning
that indicates that the filter has not been
able to regenerate automatically and that you
must perform a cleaning cycle, as indicated
in ››› page 41
. WARNING
● The diesel engine particulate filter may
reach extremely high temperatures; the vehi-
cle should be parked so that the exhaust pipe
does not come into contact with flammable
materials underneath the vehicle. Otherwise
there is a risk of fire. CAUTION
● Your vehicle is not designed to use biodie-
sel fuel. Never, under any circumstances re-
fuel with biodiesel. The use of biodiesel fuel
could damage the engine and the fuel sys-
tem. The addition of biodiesel to diesel by
the diesel producer in accordance with stand-
ard EN 590 is authorised and will not cause
damage to the engine or the fuel system.
● Using diesel fuel with a high sulphur con-
tent may significantly reduce the useful life of
the diesel particulate filter. Your Technical
Service will be able to tell you which coun-
tries have diesel with a high sulphur content. Economical and environmentally
friendly driving
Fuel consumption, environmental pollution
and wear to the engine, brakes and tyres de-
pends in large part on your driving style. By
adopting an economical driving style and an-
ticipating the traffic situation ahead, you can
easily reduce fuel consumption by 10-15%.
132

Driving
Some tips on how to help you reduce pollu-
tion while saving money are listed below.
Drive anticipating the traffic situation
A vehicle uses most fuel when accelerating.
When you anticipate situations, 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
ahe a
d. 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 iner-
tia).
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: shift up from first to second
gear as soon as possible. We recommend
that, whenever possible, you change to a
higher gear upon reaching 2000 rpm. Follow
the “recommended gear” indication that ap-
pears on the instrument panel ››› page 47.
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 in- crease 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 cross-
ings or at traffic lights with a long red phase.
The fuel saved after only 30 - 40 seconds is
greater than the amount of fuel needed to re-
start the engine.
The engine takes a long time to warm up
when it is idling. Mechanical wear and pollu-
tant emissions are also especially high dur-
ing 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 con-
sume more than the required amount of fuel.
A well-serviced engine gives you the benefit
of
improved fuel efficiency as well as maxi-
mum reliability and an enhanced resale val-
ue.
A badly serviced engine can consume up to
10% more fuel than necessary.
Avoid short journeys
To reduce the consumption and emission of
polluting exhaust gases, the engine and the exhaust gas filtration systems should reach
the optimum operating temperature.
With the en

gine cold, fuel consumption is
proportionally higher. The engine does not
warm up and fuel consumption does not nor-
malise until having driven approximately four
kilometres. This is why we recommend avoid-
ing short trips whenever possible.
Maintain the correct tyre pressures
Bear in mind that keeping the tyres at an ad-
equate pressure saves fuel. If the tyre pres-
sure is just one bar (14.5 psi / 100 kPa) too
low, fuel consumption can increase by as
much as 5%. Due to the greater rolling resist-
ance, under-inflation also increases tyre wear
and impairs handling.
The tyre pressures should always be checked
when the tyres are cold.
Do not u

se winter tyres
all year round as they
increase fuel consumption by up to 10%.
Avoid unnecessary weight
Given that every kilo of extra weight
will in-
crease the fuel consumption, it is advisable
to always check the luggage compartment to
make sure that no unnecessary loads are be-
ing 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 km/h (62 mph) »
