Intr oduction The vehicle roof has been designed to opti-
mi
se aer
ody

namics. For this reason, cross
170

Transport and practical equipment
bars or conventional roof carrier systems can-
not be sec
ur
ed to the roof water drains.
As the roof water drains are integrated in the
roof to reduce air resistance, only SEAT-ap-
proved cross bars and roof carrier systems
can be used.
Cases in which cross bars and the roof carri-
er system should be disassembled.
● When they are not used.
● When the vehicle is washed in a car wash.
● When the vehicle height exceeds the maxi-
mum height, for ex
ample, in some garages.WARNING
When heavy or bulky loads are transported
on the roof c

arrier system, car driving per-
formance is affected, as the centre of gravity
shifts and there is greater wind resistance.
● Always secure the load properly using belts
or retainin
g straps that are suitable and in a
good condition.
● Bulky, heavy, long or flat loads have a neg-
ative effect
on aerodynamics, the centre of
gravity and driving performance.
● Avoid sudden braking and manoeuvres.
● Adapt your speed and driving style at all
times t
o suit visibility, weather, road and traf-
fic conditions. CAUTION
● Remo v

e the cross bars and the roof carrier
system before entering a car wash.
● Vehicle height is increased by the installa-
tion of cr
oss bars or a roof carrier system and
the load secured on them. For this purpose,
check that your vehicle's height does not sur-
pass the headspace limit, for example, for un-
derpasses or for entering garage doors.
● Cross bars, a roof carrier system and the
load sec
ured on them should not interfere
with the roof aerial or hamper the path of the
panoramic sun roof ››› page 138 and the rear
lid.
● On opening the rear lid make sure that it
does not
knock into the roof load. For the sake of the environment
When cross bars and a roof carrier system are
ins t

alled, the increased air resistance means
that the vehicle uses more fuel. Attach the cross bars and the roof car-
rier sy

Incorrect attachment and use of the cross-
bar s

and the roof carrier system may cause
the whole system to detach from the roof and
cause an accident and injuries.
● Always take the manufacturer assembly in-
structions
into account.
● Use only crossbars and the roof carrier sys-
tem when they ar
e in perfect condition and
are properly secured.
● Secure the crossbars and the roof carrier
syst
em properly.
● Check threaded joints and attachments
travel
ling and if necessary tighten them after
you have travelled a short distance. When
making long trips, check the threaded joints
whenever you stop for a rest.
● Always fit the special roof carrier systems
correctly
for wheels, skis and surfboards, etc.
● Do not modify or repair the crossbars or
roof c
arrier system. Note
Always read the assembly instructions that
come w ith the c

rossbars and the roof carrier
system carefully and keep them in the vehi-
cle. Loading the roof carrier system
The load can only be secured if the crossbars
and the roof
c

arrier system are properly in-
stalled ››› .
Max imum authori

sed roof load
The maximum permissible roof load is 75 kg.
This figure comes from the combined weight
of the roof carrier, the cross bars and the load
itself on the roof ››› .
A lw
a

ys check the weight of the roof carrier
system, the cross bars and the weight of the
load to be transported and weigh them if
necessary. Never exceed the maximum au-
thorised roof load.
If you are using cross bars and a roof carrier
with a lower weight rating, you will not be
able to carry the maximum authorised roof
load. In this case, do not exceed the maxi-
mum weight limit for the roof carrier which is
listed in the fitting instructions.

● Never exceed the load capacity of the cross
bars
and the roof carrier system, even if the
maximum authorised roof load has not been
reached.
● Secure heavy items as far forward as possi-
ble and di
stribute the vehicle load uniformly. WARNING
If the load is loose or not secured, it could fall

Viewing Climatronic information
On the screen of Climatronic control unit and
on the screen of the factory-fitted Easy Con-
nect system, the theoretical values of the
temperature zones are shown.
The unit of temperature measurement can be
changed in the Easy Connect system.
Dust and pollen filter
The dust and pollen filter with its activated
charcoal cartridge serves as a barrier against
impurities in the air taken into the vehicle in-
terior.
The dust and pollen filter must be changed
regularly so that air conditioner performance
is not adversely affected.
If the filter loses efficiency prematurely due
to use in areas with very high levels of air
pollution, the filter must be changed more
frequently than stated in the Service Sched-
ule. WARNING
Reduced visibility through the windows in-
cr e

ases the risk of serious accidents.
● Always ensure that all windows are free of
ice and sno
w, and that they are not fogged,
so as to maintain good visibility of everything
outside.
● 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. Only drive when
you have good visibility.
● Always ensure that you use the heating
syst
em, fresh air system, air conditioner and
the heated rear window to maintain good visi-
bility to the outside.
● 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. » 173

Driving
The handbrake should be applied firmly to
pr ev
ent
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. 196.
Releasing the handbrake
– Pull the lever up slightly and press the re-
lea

se knob in the direction of the arrow
››› Fig. 196 and guide the handbrake lever
down fully ››› .
A lw
a

ys pull the handbrake all the way up, so
there is less risk of driving off with it still en-
gaged ››› .
The h andbr
ak

e 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 u se the h

andbrake to stop the vehi-
cle when it is in motion. The braking distance is considerably longer, because braking is
only
ap

plied to the rear wheels. Risk of acci-
dent!
● If the handbrake is only partially released,
this w
ill 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 vehic

le. Put it in 1st gear as well. Parking
The handbrake should always be firmly ap-
p
lied when the
v

ehicle 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. T

urn the steering wheel
slightly to engage the steering lock.
– Never leave a vehicle key in the vehicle. Additional notes on parking the vehicle on
gradient

s:
Turn the steering wheel so that the vehicle
rolls against the kerb if it started to roll.
● If the vehicle is parked facing downhil
l,
turn the front wheels so that they point to-
wards the kerb .
● If the vehicle is parked facing uphill
, turn
the front wheels so that they point away from
the kerb.
● Secure the vehicle as usual by applying the
handbrak
e firmly and putting it in 1st gear. WARNING
● Tak e me

asures to reduce the risk of injury
when you leave your vehicle unattended.
● Never park where the hot exhaust system
coul
d ignite inflammable materials, such as
dry grass, low bushes, spilt fuel etc.
● Never allow vehicle occupants to remain in
the vehic
le 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 cou
ld set the vehicle in motion, for ex-
ample, by releasing the handbrake or the
gearbox lever. » 185
