If the vehicle keys are used negligently or
without pr oper att

ention, accidents and se-
rious injuries can occur.

Note
If the selector lever is left for a long time in
a position other than P with the ignition off ,
the 12-v
olt battery may discharge. Driving with an automatic gearbox
Driving down slopes
The st

ope, the higher the selected
brake energy recuperation level will have to
be. A high recuperation level increases the
braking effect of the electric engine. Never let
the vehicle roll downhill with the selector lev-
er in the neutral position N.

Driving
At high speed and with the windscreen wipers
activ at
ed, 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 ››› .
F ault in the br

ake system
If the brake 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 re-
member that you will have to apply more pressure on the brake pedal and allow for
longer st

opping distances.
Low brake fluid level
Malfunctions can occur in the brake system if
the brake fluid level is too low. The brake fluid
level is monitored electronically.
Brake servo
The electromechanical brake servo increases
the pressure that you exert when you press
the brake pedal. It only works when the vehi-
cle’s ignition or drive system is switched on. WARNING
Any anomaly in the brake system can in-
cr ease the br

aking distance, with the re-
sulting risk of an accident.

Electronic Stability Control (ESC)*
The ESC helps t
o impr

ove safety. It reduces
the tendency to skid and improves the stabili-
ty 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 vehicle
by braking individual wheels or by reducing
the engine torque. The warning lamp will
flash on the instrument panel when the ESC is
intervening !.
The ESC includes the anti-lock brake system
(ABS), the hydraulic brake assist (HBA), the
traction control system (ASR) and the elec-
tronic differential lock (EDS)
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 pedal
pul
sat

e while the ABS is working.
If the running gear or brake system is modi-
fied, the effectiveness of the ABS could be se-
verely limited.
Hydraulic Brake Assist (HBA)*
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
gradient.
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).
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. Electronic brake pressure distribution
(EBV)
In all vehicl
es, when the brakes are applied,
the centre of gravity of the vehicle moves for-
ward. As a consequence, there is a danger
that the rear wheels may lock due to their low
traction. The electronic brake pressure distri-
bution controls the brake pressure for the rear
wheels and ensures that this pressure is dis-
tributed optimally between the front and rear
axles. Under normal circumstances it pre-
vents the rear part of the vehicle from skid-
ding due to excessive braking of the rear
wheels. The function of the electronic brake
pressure distribution is incorporated in the
ABS function.
Electromechanical brake servo (eBKV)
With the ignition switched on, the electrome-
chanical brake servo supports the force of
the foot by increasing the pressure that the
driver exerts on the brake pedal. After discon-
necting the ignition, the assistance of the
brake servo is progressively reduced. Once
stopped, immobilise the vehicle to prevent it
from moving ››› page 159.
If the electromechanical brake servo does
not work, the yellow control lamps

The high-voltage battery is discharged. There is only
sufficient autonomy for a few hundred metres. Stop
the vehicle in a safe place. Charge the high-voltage
battery immediately. The control lamps light up together when the
ignition is s

ter approximately 2 seconds. This is the time
taken for the function check. WARNING

Saf
ety warnings for performing
works in the engine compartment The engine compartment of the vehicle is a
danger
ous ar

ea. You should only perform
works in the engine compartment if you have
good knowledge of the necessary operations
and the general safety measures, and if you
have adequate tools, means and operating
fluids. Works performed inadequately, could
lead to serious injuries ››› . In this case, seek
a specialised w orkshop t

o perform all the
works. SEAT recommends visiting a SEAT
dealership for this.
Before performing any work in the engine
compartment, always park the vehicle on
level and firm ground, taking all necessary
safety precautions.
Only specialised workshops qualified ac-
cording to the SEAT guidelines are authorised
to perform works on the high-voltage system
››› .
WARNING
The voltage of the high-voltage system and
of the high-v olt

age battery could be fatal! Touching damaged high-voltage cables
(or
ange col

our) and the high-voltage bat-
tery could cause an electrical shock with
deathly consequences. The high-voltage
system may be active even with the ignition
disconnected!

Verification and replacement
on level ground, the wheels must be locked
and, wher
e appr
opriate, the vehicle key
must be removed from the ignition lock.
