wheel Seat Leon SC 2015 Workshop Manual

Operation
A cold engine consumes a disproportionate
amou nt
of
fuel. The engine reaches its work-
ing temperature after about four kilometres
(2.5 miles), when fuel consumption will re-
turn to a normal level.
Check tyre pressure
Always make sure the tyres are inflated to the
correct pressures ››› page 256 to save fuel. If
the pressure is below half bar, fuel consump-
tion may increase by 5%. Due to the greater
rolling resistance, under-inflation also increa-
ses tyre wear and impairs handling.
Do not use winter tyres all year round as they
increase fuel consumption by up to 10%.
Avoid carrying unnecessary loads
Given that every kilo of extra weight will in-
crease the fuel consumption, it is advisable
to always check the luggage compartment to
make sure that no unnecessary loads are be-
ing transported.
Since the luggage rack increases the aerody-
namic drag of the vehicle, you should remove
it when not needed. This will save, at a speed
of 100-120 km/h (60-75 mph), 12% of fuel.
Save electrical energy
The engine drives the alternator, thereby gen-
erating electricity. This implies that any in-
crease in power consumption also increases
fuel consumption! For this reason, switch off any unneeded electrical devices. Devices that
use a lot of
electricity includes the blower at
a high setting, the rear window heating or
the seat heating*. Driver assistance systems
Br ak
in
g and stability systems
Electronic Stability Control (ESC) The ESC helps to improve safety. It reduces
the tendency
t

o skid and improves the stabil-
ity and roadholding of the vehicle. The ESC
detects critical handling situations, such as
vehicle understeer or oversteer, or wheelspin
on the driving wheels. It stabilises the vehi-
cle by braking individual wheels or by reduc-
ing the engine torque. The warning lamp will
flash on the instrument panel when the ESC
is intervening .
ESC includes the Anti-lock brake system
(ABS), the brake assist system, the traction
control system (ASR), electronic differential
lock (EDL), electronic self-locking*, selective
torque control* and tractor-trailer sway miti-
gation*. ESC also helps stabilise the vehicle
by changing the torque.
Anti-lock brake system (ABS)
ABS prevents the wheels from locking up un-
der braking until the vehicle has reached a
virtual standstill. You can continue to steer
the vehicle even when the brakes are on full.
Keep your foot on the brake pedal and do not
pump the brakes. You will feel the brake ped-
al pulsate while the ABS is working.
178

Driver assistance systems
Brake assist system
The br ak
e a
ssist system can reduce the re-
quired braking distance. The braking force is
automatically boosted if you press the brake
pedal quickly in an emergency. You must
keep pressing the brake pedal until the dan-
ger has passed.
Traction control system (ASR)
In the event of wheelspin, the traction control
system reduces the engine torque to match
the amount of grip available. This helps the
car to start moving, accelerate or climb a gra-
dient.
Electronic differential lock (EDL)
When the EDL detects wheelspin, it brakes
the spinning wheel and directs the power to
the other driven wheel. This function is active
up to approximately 100 km/h.
To prevent the disc brake of the braked wheel
from overheating, the EDL cuts out automati-
cally if subjected to excessive loads. The ve-
hicle can still be driven. The EDL will switch
on again automatically when the brake has
cooled down.
Tractor-trailer sway mitigation*
If the vehicle is pulling a trailer, it will control
the following: Tractor-trailers tend to sway.
When the swaying of the trailer is felt by the
vehicle and detected by the ESC, it will auto- matically brake the towing vehicle within the
limits of the sy
stem and mitigate the sway.
Tractor-trailer sway mitigation is not available
in all countries.
Electronic torque management (XDS)
When taking a curve, 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 (out-
er wheel) receives less drive torque than the
inner wheel. This may mean that in certain
situations the torque delivered to the inner
wheel is too high, causing the wheels to
spin. On the other hand, the outer wheel is
receiving 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's
desired trajectory is much more precise.
The XDS system works in combination with
the ESC and is always active, even when ASR
traction control is disconnected, or the ESC in
Sport mode or disconnected. Multi-collision brake
In an accident, the mu
lti-collision brake can
help the driver by braking to avoid the risk of
skidding during the accident, which could
lead to further collisions.
The multi-collision brake works for front, side
or rear accidents, when the airbag control
unit records its activation level and the acci-
dent takes place at a speed of over 10 km/h
(6 mph). The ESC automatically brakes the
vehicle, as long as the accident has not dam-
aged the ESC, the brake hydraulics or the on-
board network.
The following actions control automatic brak-
ing during the accident:
● When the driver presses the accelerator,
the automatic
braking does not take place.
● When the braking pressure through press-
ing the brak
e pedal is greater than the sys-
tem’s braking pressure the vehicle will brake
automatically.
● Multi-collision braking will not be available
if ESC
is malfunctioning. WARNING
● The ESC, ABS, ASR, EDL, el ectr

onic self-
locking differential or selective torque control
systems cannot exceed the limits imposed by
the laws of physics. Always bear this in mind, » 179

Safety

Operation
especially on wet or slippery roads. If you no-
tice the sy
s
tems cutting in, you should re-
duce your speed immediately to suit the road
and traffic conditions. Do not be encouraged
to take risks by the presence of more safety
systems. If you do, an accident may occur.
● Please remember that the accident risk al-
way
s increases if you drive fast, especially in
corners or on a slippery road, or if you follow
too close behind the vehicle in front of you.
The ESC, ABS, brake assist, EDL, electronic
self-locking and selective torque control sys-
tems cannot prevent accidents: risk of acci-
dents!
● Accelerate with caution on slippery surfa-
ces
(for example, icy or snow-covered). De-
spite the control systems, the driven wheels
could spin, affecting the stability of the vehi-
cle: risk of accident! Note
● The ABS and ASR w i

ll only operate correctly
if the four wheels have identical tyres. Any
differences in the rolling radius of the tyres
can cause the system to reduce engine power
when this is not desired.
● The regulating processes of the systems
can mak
e noises when they intervene.
● If the warning lamp  lights up
, or  alter-
natively, there could be a fault ››› page 108. Switching on/off the ESC and ASR

ill be limited to allow for a sportier
drive. The driving wheels could spin and the
vehicle could “skid”. ●
If the E SC/ASR i

s deactivated, the vehicle

New brake pads
F
or 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 cert

ain 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 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

Operation
Fault in the brake system
If the br
ak
e pedal travel should ever increase
suddenly, this may mean that one of the two
brake circuits has failed. Drive immediately
to the nearest 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. CAUTION
● Never l et

the brakes “drag” by leaving your
foot on the pedal when it is not necessary to
brake. This overheats the brakes, resulting in
longer stopping distances and greater wear.
● Before driving down a long, steep gradient,
it is
advisable to reduce speed and select a
lower gear. This makes use of engine braking
and relieves the brakes. If you still have to
use the brakes, it is better to brake firmly at
intervals than to apply the brakes continu-
ously. Note
● If the br ak

e servo is out of action, for exam-
ple when the car is being towed, you will
have to press the brake pedal considerably
harder than normal to make up for the lack of
servo assistance.
● If you wish to equip the vehicle with acces-
sories s
uch as a front spoiler or wheel covers,
it is important that the flow of air to the front
wheels is not obstructed, otherwise the
brakes can overheat. Hill driving assistant*
This function is only included in vehicles with
E
SC.
The hi l

l driving assistant helps the driver to
move off and upward on a hill when the vehi-
cle is stationary. The system maintains brake pressure for ap-
prox

imately two seconds after the driver
takes his foot off the brake pedal to prevent
the vehicle from lurching backward when it is
started. During these 2 seconds, the driver
has enough time to release the clutch pedal
and accelerate without the vehicle moving
and without having to use the handbrake,
making start-up easier, more comfortable
and safer.
These are the basic operation conditions:
● being on a ramp or hill/slope,
● doors closed,
● vehicle completely stationary,
● engine running and foot on the brake,
● besides having a gear engaged or being in
neutral f
or manual gear change and with the
selector lever at position S, D or R for an au-
tomatic gearbox.
This system is also active when reversing up-
hill. WARNING
● If y

ou do not start the vehicle immediately
after taking your foot off the brake pedal, the
vehicle may start to roll back under certain
conditions. Depress the brake pedal or use
the hand brake immediately.
● If the engine stalls, depress the brake ped-
al or u
se the hand brake immediately.182

table on page 2
The Start-Stop system helps save fuel and re-
duce CO 2 emissions.
In Start-Stop mode, the engine will automati-
cally switch off when the vehicle stops, when
stopping at traffic lights for example. The ig-
nition remains switched on during the stop-
ping phase. The engine automatically
switches back on when required.
As soon as the ignition is switched on, the
Start-Stop function is automatically activa-
ted.
Basic requirements for the Start-Stop mode ● The driver door must be closed. ●
The driver mu s

t have their seat belt fas-
tened.
● The bonnet must be closed.
● The vehicle must have travelled at more
than 4 km/h (2 mph) sinc
e the last stop.
● The vehicle cannot be towing a trailer. WARNING
● Never sw it

ch the engine off until the vehi-
cle is stationary. The brake servo and power
steering functions will not be completely cov-
ered under warranty. More force may also be
needed to turn the steering wheel or to brake.
As you cannot steer and brake in the normal
manner, there is a greater risk of accidents
and serious injury.
● Never remove the key from the ignition if
the vehic
le is in motion. Otherwise, the steer-
ing could lock making it impossible to steer
the vehicle.
● To avoid injury, make sure that the Start-
Stop sys
tem is switched off when working in
the engine compartment ››› page 185. CAUTION
The Start-Stop system must always be
swit c

hed off when driving through flooded
areas ››› page 185. Stopping/Starting the engine
Vehicles with a manual gearbox
– When the vehicle is stopped, put it into
neutral and r

elease the clutch pedal. The
engine will switch off. The warning lamp 
will appear on the instrument panel dis-
play.
– When the clutch pedal is pressed the en-
gine wil

l start up again. The warning lamp
will switch off.
Vehicles with an automatic gearbox
– Use the foot brake to bring the vehicle to a
stop and k

eep the brake pedal pressed
down with your foot. The engine will switch
off. The warning lamp  will appear in the
display.
– When you take your foot off the brake pedal

Change from position D to P to prevent the
engine from accidentally starting when
changing and passing by position R. Note
● You c an c

ontrol whether the engine should
switch off or not by reducing or increasing the
brake force applied. While the vehicle re-
mains stopped, the engine will not stop if the
brake pedal is slightly pressed, in traffic jams
with frequent stopping and starting for exam-
ple. As soon as strong pressure is applied to
the brake pedal, the engine will stop.
● In vehicles with manual gearbox, during
the stop

The adaptive cruise control (ACC) is an exten-
sion of the normal cruise control system
(CCS) ››› .
The A C
C

function allows the driver to estab-
lish a cruise speed of between 30 and 160
km/h (18 and 100 mph), as well as the tem-
porary distance required with regard to the
vehicle in front. The ACC function will adapt
the vehicle's cruise speed at all times, main-
taining a safe distance with the vehicle in
front.
The ACC function is based on a radar sensor
that can measure the distance to the vehicles
in front. If the vehicle is equipped with automatic
gearbo

x, the ACC can brake the vehicle until
it stops completely if a vehicle in front of it
stops.
Driver intervention prompt
During driving, the ACC is subject to certain
limitations inherent in the system. In other
words, in certain circumstances the driver will
have to adjust speed him or herself, as well
as the distance from other vehicles.
In this case, the instrument panel screen will
warn you to intervene by applying the brake
and a warning tone will be heard
››› page 188. WARNING
The intelligent technology in the ACC cannot
ov er

come the system's inherent limitations
or change the laws of physics. If used negli-
gently or involuntarily, it may cause serious
accidents and injuries. The system is not a re-
placement for driver awareness.
● Adapt your speed and safe distance to the
vehicl
e in front of you at all times to suit visi-
bility, weather, road and traffic conditions.
● Do not use the ACC when visibility is bad,
on steep r
oads, with several bends or in slip-
pery circumstances such as snow, ice, rain or
loose gravel, or on flooded roads.
● Never use the ACC when driving off-road or
on unpav
ed roads. The ACC has been de-
signed for use on paved roads only. ●
The AC C

does not react on approaching a
fixed obstacle, such as the tail of a traffic
jam, a damaged vehicle or a vehicle stopped
at the traffic lights.
● The ACC does not react to people or animal
or vehic
les crossing your path or which ap-
proach you head-on in the same lane.
● If the ACC does not reduce speed sufficient-
ly, brak
e the vehicle immediately by applying
the pedal.
● If you are driving using the spare wheel,
the ACC
system could automatically switch
off during the journey. Switch off the system
when starting off.
● If the vehicle continues to move involuntar-
ily af
ter a driver intervention prompt, brake
the vehicle by applying the pedal.
● If the dash panel displays a driv
er interven-
tion prompt, adjust the distance yourself.
● The driver should be ready to accelerate or
brake b
y him/herself at all times. CAUTION
If you have the sensation that the radar sen-
sor is d

amaged, disconnect the ACC. This will
avoid possible damage. If this occurs have it
adjusted.

Operation
●
In comp l
ex driving situations, the Front As-
sist may issue unnecessary warnings and in-
tervene unnecessarily in braking, such as in
traffic islands.
● If the operation of the Front Assist is im-
paired, f
or example, by dirt or because the ra-
dar sensor has lost its settings, the system
may issue unnecessary warnings and inter-
vene inopportunely in the braking.
● During driving, the Front Assist does not re-
act to peop
le or animals or vehicles crossing
your path or which approach you head-on in
the same lane.
● The driver must always be ready to take
over the c
ontrol of the vehicle. Note
● When the Front As

sist causes a braking,
the brake pedal is “harder”.
● Automatic interventions by the Front Assist
on the brake
s may be interrupted by pressing
the clutch, accelerator or moving the wheel.
● If the Front Assist does not work as descri-

The C ity Emergency braking function picks
up, at speeds between 5 km/h (3 mph) and
30 km/h (19 mph) approximately, the traffic
situation in front of the vehicle up to a dis-
tance of about 10 m. If the system detects a possible collision with
a v
ehic

le in front of it, the vehicle prepares
for a possible emergency braking ››› .
If the driv

effect driving to reduce speed in the event of
a collision. The system can thus help to re-
duce the consequences of an accident.
