2016 Seat Leon 5D traction control

The essentials
Driver information system Intr oduction With the ignition switched on, it is possible
to r
e
ad the different functions of the display
by scrolling through the menus.
In vehicles with multifunction steering wheel,
the multifunction display can only be operat-
ed with the steering wheel buttons.
The number of menus displayed on the in-
strument panel will vary according to the ve-
hicle electronics and equipment.
A specialised workshop will be able to pro-
gramme or modify additional functions, ac-
cording to the vehicle equipment. SEAT rec-
ommends visiting a SEAT Official Service.
Some menu options can only be read when
the vehicle is at a standstill.
As long as a priority 1 warning is displayed, it
will not be possible to read the menus. Some
warning messages can be confirmed and
made to disappear with the windscreen wiper
lever button or the multifunction steering
wheel button.
The information system also provides the fol-
lowing information and displays (depending
on the vehicle's equipment):

Operation
Brake servo
The br ak
e ser
vo 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. Braking and stability systems
El ectr
onic

Stability Control (ESC) The ESC helps to improve safety. It reduces
the t
endency
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 c

hanging 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.
Brake assist system
The brake assist 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 (62 mph).
176

Driving
To prevent the disc brake of the braked wheel
fr om o
v
erheating, 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 system 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 cou
nter 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 multi-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-c
ollision 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,
especially on wet or slippery roads. If you no-
tice the systems 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. » 177

se note that when the ASR and ESC
are deactivated, the wheels may start to spin,
causing the vehicle to lose grip. Risk of acci-
dent!
● After putting the vehicle into gear, the
“sport” mode of
the ESC should be deactiva-
ted again by briefly pressing the OFF but-
ton. Note
● Aft er u

sing the Launch control programme,
the temperature in the gearbox may have in-
creased considerably. In this case, the pro-
gramme could be disabled for several mi-
nutes. The programme can be used again af-
ter the cooling phase.
● Accelerating with the Launch control pro-
gramme pl
aces a heavy load on all parts of
the vehicle. This can result in increased wear
and tear. Downhill speed control*
The downhill speed control function helps
the driver when driv
in

g down steep gradi-
ents.
Downhill speed control is activated when the
selector lever is in D/S and the driver applies
the foot brake. The automatic gearbox auto-
matically engages a lower gear that is suita-
ble for the slope. The downhill speed control
function attempts to maintain the speed at
which the vehicle was travelling when the
foot brake was applied (subject to the laws of
physics and technical drive limitations). It
may be necessary to adjust the speed again
using the foot brake in certain situations. Giv-
en that the downhill speed control can only
change down to 3rd gear, on very steep de-
scents the tiptronic mode may be required. In
this case, manually reduce the tiptronic to
2nd or 1st gear to use the engine brake and
reduce the charge on the brakes.
Downhill speed control is deactivated as
soon as the road levels out again or you
press the accelerator pedal.
On vehicles with cruise control system*
