2018 Seat Leon brake

Start and driving
Wet roads or road salt
In cert ain sit
uations (f
or 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

Driving
Electronic torque management (XDS)
When t aking a curv
e
, the driveshaft differen-
tial mechanism allows the outer wheel to turn
at a higher speed than the inner wheel. In this
way, the wheel that is turning faster (outer
wheel) receives less drive torque than the in-
ner wheel. This may mean that in certain sit-
uations the torque delivered to the inner
wheel is too high, causing the wheels to spin.
On the other hand, the outer wheel is receiv-
ing a lower drive torque than it could transmit.
This causes an overall loss of lateral grip on
the front axle, resulting in understeer or
“lengthening” of the trajectory.
The XDS system can detect and correct this
effect via the sensors and signals of the ESC.
Via the ESC, the XDS will brake the inside
wheel and counter the excess driving torque
of that wheel. This means that the driver

Foresight when driving
Accel er
ation causes the v
ehicle to consume
more fuel. If you think ahead when driving,
you will need to brake less and thus acceler-
ate less. Wherever possible, let the car roll
slowly to a stop, with a gear engaged (for in-
stance when you can see that the next traffic
lights are red). This takes advantage of the
engine braking effect, reducing wear on the
brakes and tyres. Emissions and fuel con-
sumption will drop to zero due to the overrun
fuel cut-off.
Changing gear to save energy
An effective way of saving is to change in ad-
vance to a higher gear. Running the engine at
high rpm in the lower gears uses an unneces-
sary amount of fuel.
Manual transmission: shift up from first to
second gear as soon as possible. In any case,
we recommend that you change to a higher
gear upon reaching 2,000 rpm. 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 trav
elling at top speed, whenever pos-
sible. Fuel consumption, emission of harmful
gases and noise pollution multiply dispropor-
tionately as speed is increased. Driving at
moderate speeds will help to save fuel.
Reduce idling time
In vehicles with the Start-Stop system idling is
automatically reduced. In vehicles without
the Start-Stop system it is worth switching off
the engine, for example, at level crossings
and at traffic lights that remain red for long
periods of time. When an engine has reached
operating temperature, and depending on
the cylinder capacity, keeping it switched off
for a minimum of about 5 seconds already
saves more than the amount of fuel necessa-
ry for restarting.
The engine takes a long time to warm up
when it is idling. Mechanical wear and pollu-
tant emissions are also especially high during
this initial warm-up phase. It is therefore best
to drive off immediately after starting the en-
gine. Avoid running the engine at high speed.
Regular maintenance
Regular servicing helps in saving fuel even
before the engine is started. A well-serviced
engine gives you the benefit of improved fuel
efficiency as well as maximum reliability and
an enhanced resale value. A badly serviced engine can consume up to 10% more fuel
than necessary.
Avoid short journeys
The engine and cat
alytic converter need to
reach their optimal operating temperature
in order to minimise fuel consumption and
emissions.
A cold engine consumes a disproportionate
amount of fuel. The engine reaches its work-
ing temperature after about four kilometres
(2.5 miles), when fuel consumption will return
to a normal level.
Check tyre pressure
Always make sure the tyres are inflated to the
correct pressures

ector lever is in
the positions P, D, N and S 1)
, in addition to
when in Triptonic mode. With the selector lev-
er in position P, the engine will also remain
switched off when you take your foot off the
brake pedal. In order to start the engine up
again the accelerator must be pressed, or
another gear engaged or the brake released.
If the selector lever is placed in position R dur-
ing the stopping phase, the engine will start
up again.
Change from position D to P to prevent the
engine from accidentally starting when
changing and passing by position R.

Adaptive Cruise Control (ACC)
In vehicles with ACC function, the engine will
start up again in certain operating conditions
if the radar sensor detects that the vehicle
ahead drives off again. WARNING
