Securing the base supports and roof carrier
system
The roof carrier system must always be instal-
led exactly according to the instructions pro-
vided.
Two-door vehicles: the holes and marks indi-
cating the fitting points for base front sup-
ports are in the lower half of the roof struts
››› Fig. 137 (enlarged left image). The holes
and marks are only seen with the door open.
The fitting marks for base rear supports are in
the upper half of the windows ››› Fig. 137 (en-
larged right image).
Four-door vehicles: the holes or marks indi-
cating the fitting points for base supports are
in the lower half of the roof struts and can on-
ly be seen with the door open ››› Fig. 138.
The base support should only be fitted to the
points indicated in the diagram . WARNING
If the base supports and the roof carrier sys-
tem ar e inc

orrectly fitted or used in an unsuit-
able manner, the entire system could break
free causing accident and injury.
● Always take the manufacturer assembly in-
structions
into account. ●
Only u

se base supports and roof carrier
systems that are not damaged and are cor-
rectly fitted.
● The base support should only be fitted to
the points indic
ated in the diagram
››› Fig. 137.
● Secure the base supports and roof carrier
syst
em correctly.
● Check the screws and attachments before
driving and af
ter a short distance. During
each long journey, check the attachments
during every break.
● Always fit the roof carrier system correctly
for wheels, sk
is and surfboards, etc.
● Never modify or repair the basic supports
or roof c
arrier system. Note
Read and take into account the instructions
included w ith the r

oof carrier system fitted
and keep them in the vehicle. Loading the roof carrier

Air conditioning
●
The max imum he
at output required to de-
frost windows as quickly as possible is only
available when the engine has reached its
normal running temperature. Only drive when
you have good visibility.
● Always ensure that you use the heating
syst
em, ventilation, air conditioner and the
heated rear window to maintain good visibili-
ty.
● Never leave the air recirculation on for a
long period of time. If
the cooling system is
switched off and air recirculation mode
switched on, the windows can mist over very
quickly, considerably limiting visibility.
● Switch air recirculation mode off when it is
not requir
ed. WARNING
Stuffy or used air will increase fatigue and re-
duce driv er c

oncentration possibly resulting
in a serious accident.
● Never leave the fresh air fan turned off or
use the air rec
irculation for long periods of
time; the air in the vehicle interior will not be
refreshed. CAUTION
● Swit c

h the air conditioner off if you think it
may be broken. This will avoid additional
damage. Have the air conditioner checked by
a specialised workshop.
● Repairs to the air conditioner require spe-
cia
list knowledge and special tools. SEAT rec-
ommends taking your car in for technical
service. Note
● When the coo lin

g system is turned off, air
coming from the outside will not be dried. To
avoid fogging up the windows, SEAT recom-
mends leaving the cooler (compressor) on. To
do this, press the A/C button. The button
lamp shou l

d light up.
● The maximum heat output required to de-
fros
t windows as quickly as possible is only
available when the engine has reached its
normal running temperature.
● Keep the air intake slots in front of the
winds
creen free of snow, ice and leaves to en-
sure heating and cooling are not impaired, and to prevent the windows from misting

coolant temperature is too high.
● Another fault in the vehicle. Have the air
conditioner chec
ked by a specialised work-
shop. Special features
If the humidity and t

emperature outside the
vehicle are high, condensation can drip off
the evaporator in the cooling system and
form a pool underneath the vehicle. This is
normal and does not indicate a leak! Note
After starting it, any residual humidity in the
air conditioner c ou

ld mist over the wind-

themselv
es to safety. For example, de-
pending on the time of the year, tempera-
tures inside a locked and closed vehicle can
be extremely high or extremely low resulting
in serious injuries and illness or even death,
particularly for young children.
● Never remove the key from the ignition if
the vehic
le is in motion. The steering may
lock and it will not be possible to turn the
steering wheel. CAUTION
● An attempt t

o start the engine while driving
or starting the engine immediately after turn-
ing it off can cause damage to the engine or
starter motor.
● When the engine is cold, avoid high revs
and heavy ac
celeration and do not make the
engine work hard.
● Do not push or tow start the engine. Un-
burnt f
uel could damage the catalytic con-
verter. For the sake of the environment
Do not warm the engine at idle speed; start
drivin g immedi

ately if the visibility is OK.
This helps the engine reach operating tem-
perature faster and reduces emissions. Note
● If the k ey

is left in the ignition lock with the
engine off for long periods, the vehicle bat-
tery will run flat.
● For automatic gearbox vehicles, the key can
only be r
emoved from the ignition lock if the
gear selector lever is in position P. In this
case, press and release the selector lever
locking button.
● Electrical devices with a high power con-
sumption are sw
itched off temporarily when
the engine starts.
● When the engine is started cold, there may
be stron
g vibrations for a few moments for
technical reasons. This is quite normal, and
no cause for concern.
● Natural gas engines always start up with
petrol, a

move, it will be held by the kerb.
● On slopes, turn the front wheels so that
they are ag

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

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
