prepared to use more pressure on the brake
ped al, and al
lo
w for longer stopping distan-
ces.
Brake servo
The brake servo only operates when the en-
gine is running and the pressure applied by
the driver on the brake pedal increases.
If the brake servo does not operate or the ve-
hicle must be towed, then the brake pedal
will have to be pressed with more force given
that the braking distance will be increased
when the brake servo does not operate ››› .
WARNING
New brake pads do not brake to full efficien-
cy.
● For the fir

st 320 km, new brake pads have
not y
et reached their maximum braking ca-
pacity, and need to be “run in” first. For this,
to compensate for reduced braking efficiency
the brake pedal will have to be pressed with
more force.
● To avoid losing control of the vehicle and
caus
ing serious accidents, always take great
care when driving with new brake pads.
● When running in new brake pads, always
res
pect the safety distances between you and
other vehicles and do not cause situations re-
quiring extreme braking performance. WARNING
When brakes overheat, braking is less effi-
cient and br

aking distances increase.
● When driving on slopes, brakes can be
overlo
aded and overheat quickly.
● Reduce speed or change down a gear when
faced w
ith steep and long slopes. This allows
you to use the engine braking effect and to
reduce the strain on the brake system.
● Non-standard or damaged front spoilers
coul
d restrict the airflow to the brakes and
cause them to overheat. WARNING
Wet, frozen or salt-covered brakes take lon-
ger t o en

gage and this increases braking dis-
tances.
● Test the brakes carefully.
● Dry the brakes, free them of ice and salt by
brakin
g gently several times, when visibility,
weather, and road and traffic conditions per-
mit. WARNING
Driving without the brake servo may signifi-
cantly inc

rease the braking distance and re-
sult in a severe accident.
● Never allow the vehicle to move forwards
when the engine is
switched off.
● If the brake servo does not operate or the
vehicl
e must be towed, then the brake pedal will have to be pressed with more force given
that
the br

aking distance will be increased
when the brake servo does not operate. CAUTION
● Nev er m ak

e the brakes “slip” by pressing
the pedal gently, if it is not really necessary
to brake. Continuously pressing on the brake
pedal will heat the brakes. This could signifi-
cantly reduce braking power, increase brak-
ing distance or even result in the total failure
of the brake system.
● Reduce speed or change down a gear when
faced w
ith steep and long slopes. This allows
you to use the engine braking effect and to
reduce the strain on the brake system. Other-
wise, the brakes may overheat and fail. Only
use the brakes to reduce speed or to stop. Note
Make use, when having the front brake pads
chec k

ed, and have the rear pads checked al-
so. The thickness of the brake pads should be
checked visually and regularly, by looking
through the openings in the wheel rims or
from underneath the vehicle. If necessary, re-
move the wheels to check them thoroughly.
SEAT recommends taking your car in for tech-
nical service. 136

This could cause loss of control of the vehicle
resulting in an accident and considerable
damage.
● Use rapid acceleration only when visibility,
weather

Do not allow the brakes to “rub” for a pro-
long ed period of

time, or brake frequently or
for long periods of time. Continuous braking
heats up the brakes. This could significantly
reduce braking power, increase braking dis-
tance or even result in the total failure of the

Shifting down a gear
Shifting down a gear while driving must be
carried out gear by gear, i.e. to the gear im-
mediately preceding the current gear and at
an engine speed that is not excessive ››› .
At high s
peed

s, or high engine speeds, skip-
ping one or various gears when shifting
down a gear can cause damage to the clutch
and the gearbox, even if the clutch is not en-
gaged during the process ››› .
WARNING
When the engine is running, the vehicle will
st ar

t to move as soon as a gear is engaged
and the clutch released. ●
Never en g

age the reverse gear when a vehi-
cle is moving forward. WARNING
As a consequence of shifting down a gear in-
c orr ectly

, you may lose control of the vehicle
and cause an accident with serious conse-
quences. CAUTION
If, at high speeds or high engine speeds, the
ge ar l

ever is shifted down to a gear that is too
low, serious damage can be caused to the
clutch and gearbox. This may also happen if
you press the clutch pedal and it does not en-
gage. CAUTION
To prevent damage and avoid premature
we ar

, please observe the following:
● While driving, do not leave your hand rest-
ing on the ge
ar stick. The pressure applied by
your hand is transmitted to the gearbox se-
lector forks.
● Always ensure that the vehicle is complete-
ly st
opped before engaging the reverse gear.
● When changing gear, always make sure the
clutc
h pedal is pushed right to the floor.
● Never hold the vehicle “on the clutch” on
hill
s with the engine on. 138

Automatic gearbox malfunction Back-up programme
When autom
atic
gearbox warning and indica-
tion lamps light up on the instrument panel,
there may be a system malfunction
››› page 137. In the event of some faults the
automatic gearbox functions using a backup
programme. When the programme is activa-
ted, it is possible to drive the vehicle, howev-
er, at low speeds and within a selected range
of gears.
With the manual gearbox, in some cases it is
not possible to drive with all the gears .
In all cases the automatic gearbox must be
checked at a specialised workshop.
Automatic gearbox overheating
The automatic gearbox can overheat with a
prolonged start up, or when stopping and
starting continuously. This overheating is dis-
played with a warning lamp  in the instru-
ment panel. Additionally, an audible warning
can be heard. Stop and let the gearbox cool
››› .
The v
ehic

le moves forward or back despite
having selected a gear range
When the vehicle does not move in the re-
quired direction, the system may not have
the gear range correctly engaged. Press the
brake pedal and engage the gear range again. If the vehicle still does not move in the
required dir

ection, there is a system malfunc-
tion. Seek specialist assistance and have the
system checked. CAUTION
● When the ge arbo

x is displayed as overheat-
ing for the first time, the vehicle must be
parked safely or must be driven at a speed of
more than 20 km/h (12 mph).
● When the warning lamp lights up and the
audible w
arning is heard, the vehicle must be
parked safely and the engine switched off.
Let the gearbox cool down.
● To prevent damage to the gearbox, driving
must
only be continued when the warning
lamps are no longer lit up. While the gearbox
is overheated, starting up and driving, even
at a slow speed should be avoided. Recommended gear display

Operation
for the vehicle is not too different to the out-
s ide t
emper
ature. It is a good idea to air the
vehicle before starting your journey and to
drive a short distance with the windows
open. Then you can close the windows and
switch on the air conditioning. Keep windows
closed when travelling at high speeds. Driv-
ing with the windows open increases fuel
consumption.
● Switch off the seat heating when the seats
have w
armed up.
● Switch off the heated rear window when it
is not
moist or covered in ice.
Avoid short journeys
Fuel consumption is much higher when the
engine is cold, immediately after it has been
started. It takes a few kilometres of driving
for the engine to warm up and to normalise
consumption.
The engine and catalytic converter need to
reach their proper working temperature in or-
der to minimise fuel consumption and emis-
sions. The ambient temperature has a deci-
sive influence.
Fig. 147 shows the difference in consump-
tion for the same journey at +20 °C (+68 °F)
and at -10 °C (+14 °F).
Therefore, unnecessary short journeys
should be avoided. Try to combine trips. The vehicle uses more fuel in winter than in
summer, ev

en when other conditions are the
same.
The engine takes a long time to warm up
when it is idling. In addition, mechanical
wear and pollutant emissions are also espe-
cially high during this initial warm-up phase.
It is therefore best to drive off immediately af-
ter starting the engine. Doing this avoids run-
ning the engine at a high speed.
Adjusting type pressures.
Having the correct pressure in your tyres
helps to reduce rolling resistance and, as a
result reduces fuel consumption. Increasing
the tyre pressure slightly (+0.2
bar/+3 psi/+200 kPa) can help to save fuel.
When you buy new tyres, make sure they are
optimised for minimum rolling resistance.
Use low friction engine oil
The use of low viscosity totally synthetic oils,
known as low friction engine oil, helps to re-
duce fuel consumption. These oils reduce the
resistance caused by friction in the engine,
they flow around the engine more quickly
and efficiently, particularly in cold starts. The
effect is particularly noticeable in vehicles
frequently used for short journeys.
Always check the engine oil level and ob-
serve service intervals (engine oil change in-
tervals). When purchasing engine oil, always observe
leg
al requirements and ensure that the oil is
approved by SEAT.
Avoid carrying unnecessary loads
The lighter the vehicle, the more economical
and ecological the driving style. For example,
an additional weight of 100 kg will increase
fuel consumption up to 0.3 l/100 km.
Remove any unnecessary objects or loads
from the vehicle.
Remove optional equipment and unnecessa-
ry accessories
The more aerodynamic the vehicle, the lower
the fuel consumption. Optional equipment
and accessories (such as roof racks or bike
carriers) reduce the aerodynamic benefits of
the vehicle.
Therefore, we recommend you remove all op-
tional and unnecessary equipment and racks,
especially if you intend to drive at high
speeds.
Other factors which increase fuel consump-
tion (examples):
● Fault in engine management.
● Driving on hills.

● Always park your vehicle so that no part of
the exhau
st system can come in contact with
flammable materials (such as dried grass).

While the control lamps  or  r
emain lit,
the engine will have faults, there will be high-
er consumption of fuel and a loss of engine
power. Catalytic converter
The catalytic converter permits the subse-
quent tr
e

atment of the exhaust gases thus
reducing contaminating gas emissions. To
ensure a longer working life for the exhaust
system and catalytic converter in a petrol en-
gine:
● Always use unleaded petrol.
● Never run the fuel tank completely dry.
● Do not top up with too much engine oil
›› ›

page 186.
● Do not tow-start the vehicle; use the starter
cabl
es ›››
 page 42.
If you should notice misfiring, uneven run-
ning or loss of power when the car is moving,
reduce speed immediately. Have the car in-
spected by a specialised workshop. If this
happens, unburnt fuel can enter the exhaust
system and escape into the atmosphere. The
catalytic converter can also be damaged by
overheating. »

Operation
For the sake of the environment
Even when the emission control system is
work in
g perfectly, there may be a smell of
sulphur under certain conditions. This de-
pends on the sulphur content of the fuel
used. Driving abroad
In some countries, certain safety regulations
and requir
ements

are in force relating to ex-
haust gas emissions, which differ from the
technical characteristics of the vehicle. Be-
fore travelling abroad, SEAT recommends you
consult a technical service about the legal re-
quirements and the following points:
● Does the vehicle need technical modifica-
tions f

or driving abroad, for example, adjust-
ment of the headlamps?
● Does the vehicle have all the tools, diag-
nostic
s equipment and spare parts required
for inspections and repairs?
● Are there any SEAT dealers in the destina-
tion countr
y?
● For petrol vehicles: Is unleaded petrol avail-
able at
the right octane rating?
● For diesel engines: is diesel fuel available
with a low s
ulphur content?
● Are a suitable engine oil ( ›››

page 186) and
other engine fluids complying with SEAT specifications available in the destination
countr

y?
● Will the navigation system fitted at the fac-
tory
operate correctly in the destination coun-
try with the available navigation data?
● Are special tyres required in the destination
countr
y? CAUTION
SEAT does not accept liability for any damage
to the v

ehicle due to the use of a lower quali-
ty fuel, an inadequate service or the non-
availability of genuine spare parts. Driving along flooded roadways
To prevent damage to the vehicle when driv-
in
g thr
ough w

ater, for example, along a floo-
ded road, please observe the following:
● Check the depth of the water before enter-
ing the flooded z
one. The water should never
come above the lower edge of the bodywork
››› .
● Do not drive faster than a pedestrian.
● Do not stop in the water, use reverse gear
or sw it
c

h off the engine.
● Oncoming traffic will cause waves which
raise the l
evel of the water, making it difficult
to cross the water. ●
Disc
onnect the Start-Stop system whenever
crossing water. WARNING
When driving through water, mud, melted
sno w

, etc., please remember that due to
damp or frozen brake discs and shoes in win-
ter, the braking effect may be delayed, there-
fore the required braking distance is greater.
● “Dry the brakes and remove ice” by braking
caref
ully. Ensure that you are not endanger-
ing other road-users or breaking traffic regu-
lations in the process.
● After driving through water, avoid sudden
sharp manoeu
vres. CAUTION
● Drivin g thr

ough flooded areas may severely
damage vehicle components such as the en-
gine, transmission, drive train or electrical
system.
● Never drive through salt water as salt cau-
ses c
orrosion. Always rinse any parts of the
vehicle which have been in contact with salt
water. 146

Operation
Hill driving assistant* Oper ation This function is only included in vehicles with
ESC.
The hi
l
l driving assistant helps the driver to
move off and upward on a hill when the vehi-
cle is stationary.
The system maintains brake pressure for ap-
proximately two seconds after the driver
takes his foot off the brake pedal to prevent
the vehicle from lurching backward when it is
started. 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 start-up easier, more comfortable
and safer.
These are the basic operation conditions:
● being on a ramp or hill/slope,
● doors closed,
● vehicle completely stationary,
● engine running and foot on the brake,
● besides having a gear engaged or being in
neutral f

or manual gear change and with the
selector lever at positions S, D or R in vehi-
cles with an automatic gearbox.
This system is also active when reversing up-
hill. WARNING
● If y

ou 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 u
se the hand brake immediately.
● When following a line of traffic uphill, if you
want t
o prevent the vehicle from rolling back
accidentally when starting off, hold the brake
pedal down for a few seconds before starting
off. Note
