braking distance or even causes a brake
system fault.

Driving
Foresight when driving
If you think ahead when driving, you will need
t o br
ake l
ess and thus accel
erate less. Take
advantage of the inertia of the vehicle when-
ever possible, with a gear engaged. This
takes advantage of the engine braking effect,
reducing wear on the brakes and tyres. Emis-
sions and fuel consumption will drop to zero.
Changing gear to save energy
An effective way of saving is to change in ad-
vance to a higher gear.
Manual transmission: shift up from first to
second gear as soon as possible. Choosing
the right gear enables fuel savings. Select the
highest possible gear appropriate for the
driving situation (the engine should continue
functioning with cyclical regularity).
Automatic transmission: accelerate gradu-
ally and without reaching the “kick-down”
position.
Avoid driving at high speed
Avoid travelling at your vehicle

intervention of the ACC by pressing the ac-
celerator. At low speeds the function is inac-
tive, for greater comfort in a traffic jam or in
city traffic.

If the br ak

or example on long
and steep descents, the ACC may be deacti-
vated temporarily. A message will be dis-
played stating this. In this case, adaptive
cruise control cannot be activated.
Cruise control may be reactivated once the
brake temperature has dropped. The mes-
sage will disappear. If the message ACC not
available remains on for quite a long time it
means that there is a fault. Contact a speci-
alised workshop. SEAT recommends visiting a
SEAT dealership. WARNING
If you do not pay attention to the Press
the brake message, the vehicle may mo v

and crash into the vehicle ahead. Before
driving off again, check that the road is
clear. The radar sensor may not detect ob-
stacles on the road. This could cause an
accident and serious injuries. If necessary,
apply the brake. Lane Assist*
Intr oduction Fig. 281
On the windscreen: field of vision of
the L ane Assist syst
em. Using the camera located in the windscreen,
the L
ane Assist syst
em detects the possibl
e
lines dividing the l

anes. When the vehicle in-
voluntarily approaches a dividing line it has
detected, the system notifies the driver with a
corrective steering movement. The purpose is
not only to warn the driver, but also to keep
the vehicle inside the lane. This movement
can be over-regulated at any time.
No warning is produced with the turn signals
activated, given that the Lane Assist system
understands that a lane change is required. Control lamp

W et r
oads or r
oad 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 damp, 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 wipers
activated, the brake pads will briefly touch
the brake discs. This takes place, although
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 winter. The
layer of salt that accumulates on the discs
and pads can be removed by gently apply-
ing 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
