Fig. 143
Between the front seats: handbrake. Using the handbrake
●
Pull firmly in an upwards direction on the
h andbr ak

e lever while pressing the button.
● The handbrake is applied when the control
lamp 
lights up on the instrument panel
››› page 133 when the ignition is switched
on.
Releasing the handbrake
● Pull gently in an upwards direction on the
handbrak
e lever and press the lock button
››› Fig. 143 (arrow).
● Move the handbrake lever downwards
keeping the loc
k button pressed. WARNING
The incorrect use of the handbrake may result
in a serious ac

cident.
● Never use the handbrake to brake the vehi-
cle e
xcept in an emergency. The braking dis-
tance is considerably longer, because braking
is only applied to the rear wheels. Always use
the foot brake.
● Never drive with the handbrake gently ap-
plied. Thi
s can overheat the brake, affecting
the brakes system. This also causes prema-
ture wear on the rear brake pads.
● Never accelerate from the engine compart-
ment with the en
gine running and a gear en-
gaged. The vehicle could move, even if the
handbrake is applied. Note
If the vehicle moves at a speed superior to
6 km/h (4 mph) with the h andbr

ake applied,
an audible warning is sounded. Parking
When parking your vehicle, all legal require-
ments shou
l

d be observed.

Driving
● When l e
av
ing the vehicle, take all keys with
you.
● Lock the vehicle.
Additiona
l information for steep slopes and
hills
Before switching off the engine, rotate the
steering wheel so that if the vehicle should
move, it will be held by the kerb.
● On slopes, turn the front wheels so that
they are ag
ainst the edge of the kerb.
● Uphill, turn the wheels towards the centre
of the ro
ad. WARNING
The components of the exhaust system reach
ver y

high temperatures. This could cause a
fire and considerable damage.
● Always park your vehicle so that no part of
the exhau
st system can come in contact with
flammable materials (such as wood,
leaves,dried grass, or spilled fuel). CAUTION
● Spec i

al care should be taken when parking
in areas with high kerbs or fixed barriers. Ob-
jects protruding from the ground may dam-
age the bumper or other parts of the vehicle
during manoeuvres. To avoid damage, stop
before the wheels touch the barrier or kerb. ●
Spec i

al attention is required when driving
through entrances, over ramps, kerbs or oth-
er objects. The vehicle underbody, bumpers,
mudguards and running gear, and the engine
and exhaust system could be damaged as
you drive over these objects. Information on the brakes
For the first 200 to 300 km, the new brak
e
p
ads have not yet reached their maximum
braking capacity, and need to be “run in”
first ››› . The slightly reduced braking effect
c an be c
ompen

sated for by increasing pres-
sure on the brake pedal. While running in,
the full braking distance or emergency brak-
ing distance is larger then when the brake
pads have been run in. While running in,
avoid full power braking or situations requir-
ing braking performance. For example, in
heavy traffic.
The rate of wear of the brake pads depends
to a great extent on the conditions in which
the vehicle is used and the way the vehicle is
driven. If the vehicle is used frequently in city
traffic or for short trips or driven sport style,
visit a specialised workshop regularly, more
frequently than advised in the Maintenance
Programme, to have the brake pads checked.
If you drive with wet brakes, for example, af-
ter crossing areas of water, in heavy rainfall
or even after washing the car, the effect of the brakes is lessened as the brake discs are
wet or ev

en frozen (in winter). At higher
speed, “dry” the brakes as quickly as possi-
ble by braking gently several times. Only do
this without endangering vehicles behind
you or any other road users ››› .
A l a
y

er of salt on the discs and brake pads
will reduce the effectiveness of the brakes
and increase braking distance. If you drive for
a prolonged period on salted roads without
braking then brake carefully several times to
eliminate the layer of salt on the brakes ››› .
If the
v

ehicle remains parked for considera-
ble lengths of time, is used little, or if the
brakes are not used, there may be corrosion
on the brake discs and a build up of dirt on
the brake pads. If the brakes are not used fre-
quently, or if rust has formed on the discs,
SEAT recommends cleaning the pads and
discs by braking firmly a few times at a mod-
erately high speed. Only do this without en-
dangering vehicles behind you or any other
road users ››› .
F au
lt

s in the brake system
During braking, if you notice that the vehicle
does not react as usual (that the braking dis-
tance has increased suddenly) it may be pos-
sible that there is a fault in the braking sys-
tem. This is indicated by the warning lamp
. Take the vehicle to a specialised work-
shop immediately and have the fault re-
paired. Drive at a moderate speed and be »

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

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

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.

The catalytic converter permits the subse-

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. »
