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

Operation
●
Dependin g on w
eather conditions, it may
become extremely hot or cold inside the vehi-
cle. This can be fatal. Brakes
New brake pads
For the fir
s

t 400 km (250 miles), new brake
pads have not yet reached their maximum
braking capacity, and need to be “run in”
first. However, you can compensate for the
slightly reduced braking effect by applying
more pressure on the brake pedal. Avoid
overloading the brakes while running them
in.
Wear
The rate of wear on the brake pads depends
a great deal on how you drive and the condi-
tions in which the vehicle is operated. This is
a particular problem in urban traffic and
short stretches, or with very sporty driving.
Depending on the speed, the braking force
and the environmental conditions (for exam-
ple, the temperature, air humidity, etc.)
noises may be produced on braking.
Wet roads or road salt
In certain situations (for example, on driving
through flooded areas, in severe downpours
or after washing the vehicle) the braking ac- tion could be delayed if the discs and pads
are d
amp

, or frozen in winter. In this case the
brakes should be “dried” by pressing the
brake pedal several times.
At high speed and with the windscreen wip-
ers activated, the brake pads will briefly
touch the brake discs. This takes place, al-
though unnoticeable to the driver, at regular
intervals to improve the response time of the
brakes when they are wet.
The effectiveness of the brakes can also be
temporarily reduced if the vehicle is driven
for some distance without using the brakes
when there is a lot of salt on the road in win-
ter. The layer of salt that accumulates on the
discs and pads can be removed by gently ap-
plying the brakes a few times.
Corrosion
There may be a tendency for corrosion to
form on the discs and dirt to build up on the
brake pads if the vehicle is used infrequently
or the brakes are not used very often.
If the brakes are not used frequently, or if
rust has formed on the disks, it is advisable
to clean off the pads and disks by braking
firmly a few times at a moderately high speed
››› .
F au
lt

in the brake system
If the brake pedal travel should ever increase
suddenly, this may mean that one of the two brake circuits has failed. Drive immediately
to the near

est specialised workshop and
have the fault repaired. Drive there slowly
and remember that you will have to apply
more pressure on the brake pedal and allow
for longer stopping distances.
Low brake fluid level
Malfunctions can occur in the brake system if
the brake fluid level is too low. The brake flu-
id level is monitored electronically.
Brake servo
The brake servo increases the pressure you
apply to the brake pedal. It works only when
the engine is running. WARNING
● App ly

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 en
gine is stopped. Failure
to follow this instruction could result in an
accident.
● If the brake fluid loses its viscosity and is
subj
ected to heavy use, vapour bubbles can
form in the brake system. This reduces the ef-
ficiency of the brakes. 186

a specialised workshop as soon as possible
and have the engine checked.
Driving tips
Driving thr
ough flooded roadsTo prevent damage to the vehicle when driv-
in
g thr
ough w

ater, for example, along a floo-
ded road, please observe the following:
● The water should never come above the
lower edg
e of the bodywork.
● Drive at pedestrian speed. WARNING
After driving through water, mud, sludge,
etc ., the br

aking effect can be delayed slight-
ly due to moisture build-up on the discs and
brake pads. Applying the brakes carefully
several times will remove the moisture and
restore the full braking effect. CAUTION
● Drivin g thr

ough flooded areas may severely
damage vehicle components such as the en- gine, transmission, running gear or electrical
sys
t

em.
● Whenever driving through water, the Start-
Stop sys
tem* must be switched off
››› page 205. Note
● Chec k the depth of

the water before enter-
ing the flooded zone.
● Do not stop in the water, drive in reverse, or
stop the en
gine in any situation.
● Note that vehicles travelling in the opposite
direction ma
y splash water that could exceed
the maximum permitted water height for your
vehicle.
● Avoid driving through salt water (corro-
sion). Four-wheel drive
3 V
alid for vehicles: with four-wheel drive
On f
our-wheel drive models, the engine pow-
er is distributed to all four wheels
General notes
On four-wheel drive vehicles, the engine
power is distributed to all four wheels. The
distribution of power is controlled automati-
cally according to your driving style and the
road conditions. Also see ››› page 187, Brak-
ing and stability systems .The four-wheel drive is specially designed to
comp
l

ement the superior engine power. This
combination gives the vehicle exceptional
handling and performance capabilities, both
on normal roads and in more difficult condi-
tions, such as snow and ice. Even so (or per-
haps especially for this reason), it is impor-
tant to observe certain safety points ››› .
W int
er ty

res
Thanks to four-wheel drive, your vehicle will
have plenty of traction in winter conditions,
even with the standard tyres. Nevertheless,
we still recommend that winter tyres or all-
season tyres be fitted on all four wheels to
give even better braking response.
Snow chains
On roads where snow chains are mandatory,
this also applies to cars with four-wheel drive
›››  page 69.
Changing tyres
On vehicles with four-wheel drive, all four
tyres must have the same rolling circumfer-
ence. Also avoid using tyres with varying
tread depths ››› page 281.
Off-roader?
Your SEAT is not an off-road vehicle: it does
not have enough ground clearance to be
used as such. It is therefore best to avoid
