Driver assistance systems
(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 208 to save fuel. If
the pr e
ssure 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-
cr

ease 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
Braking and stability systems Electronic Stability Control (ESC) The ESC helps to improve safety. It reduces
the tendency to 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. »

The essentials

Operation
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.
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 system and mitigate the sway.
Tractor-trailer sway mitigation is not available
in all countries.
Electronic self-locking*/Selective torque
control*
When driving around bends, an electronic
self-locking intervenes. The front wheel on
the inside of the curve, or the two inside
wheels, respectively, are selectively braked
as required. This minimises the traction of
the front wheels, allowing you to take bends
with greater precision and neutrality. In cer-
tain circumstances, where roads are wet or
snow-covered, the respective system may not
intervene.
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 brake 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, electronic 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-
ways 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! 144

Operation
Ambient lighting
The ambient lighting guides located in the in-
terior front door panels of the Leon FR and
the Leon Cupra change colour from white to
red depending on the driving mode selected.
Adaptive Cruise Control (ACC) 1)
According to the active driving profile, the ac-
celeration gradient of the adaptive cruise
control varies.
Electronic self-locking differential 1)
The self-locking differential adapts its behav-
iour depending on the driving profile chosen.
Normal mode or Cupra mode can be selected
to prioritise improved traction in sport driv-
ing. Setting driving mode Fig. 165
Centre console: MODE button. You can select from
Normal
, Sport
, Eco
and In-
dividual .
You can select the required mode either by
repeatedly pressing the button MODE
››› Fig. 165 , or on the touch screen, in the
menu th at
opens when the above button is
pressed.
An icon on the Easy Connect system display
informs about the active mode.
The MODE
button light remains lit up yellow
when the active mode is different to Normal
.

profileCharacteristics
NormalOffers a balanced driving experience, suit-
able for everyday use.
SportProvides a complete dynamic performance
in the vehicle, enabling the user a more
sporty driving style.
Eco
Places the vehicle in a particularly low
state of consumption, facilitating a fuel-

fied by pressing the Profile settings but-
ton. The functions that can be adjusted
depend on the equipment fitted in the ve-
hicle.
Conven- ience a)It permits more relaxed and comfortable
