CAUTION
● Alw a

ys carefully remove the fuse box cov-
ers and refit them correctly to avoid problems
with your vehicle.
● Protect the fuse boxes when open to avoid
the entry of
dust or humidity. Dirt and humid-
ity inside fuse boxes can cause damage to
the electrical system. » 93

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.

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

Driver assistance systems
In the FR and X-PERIENCE models equipped
w ith dy
n
amic chassis control and Navi Sys-
tem Plus, the Comfort profile is also
available.
In the Leon Cupra model the four profiles are Comfort , Sport, Cupra and Individual .
The Individual profile can be configured
according to personal preferences. The other
profiles are fixed.
Description Depending on the equipment fitted in the ve-
hic
l
e,

SEAT Drive Profile can operate on the
following functions:
Engine
Depending on the profile selected, the en-
gine responds more spontaneously or more
in harmony with the movements of the accel-
erator. Additionally, when Eco mode is selec-
ted, the Start-stop function is automatically
activated.
In vehicles with automatic transmission, the
gear change points are modified to position
them in lower or higher engine speed ranges.
Additionally, the Eco 1)
mode activates the In- ertia function, enabling consumption to be
further r

educed.
In manual gearbox vehicles, Eco1)
mode cau-
ses the gear change recommendation indica-
tions that appear on the instrument panel to
vary, facilitating more efficient driving.
Dynamic chassis control (DCC)

››› table on page 2
DCC continuously adapts the shock absorb-
ers to the condition of the road and current
driving conditions, according to the pre-set
programme.
In the event of a fault in the DCC, the follow-
ing message is displayed on the instrument
screen Fault: damping setting .
Address
Power steering becomes more robust in
Sport mode to enable a sportier driving
style. In the Leon Cupra the power steering
becomes more robust in Cupra mode.
Air conditioning
In vehicles with Climatronic, this can operate
in eco 1)
mode, especially restricting fuel con-
sumption. Ambient lighting
The ambient lightin
g 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) 2)
According to the active driving profile, the ac-
celeration gradient of the adaptive cruise
control varies.
Electronic self-locking differential 2)
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. 1)
In the Leon Cupra model, Ec o
mode is selected
through the Individual profile.
2) Applies to the Leon Cupra model.
