(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
Operating mode Fig. 164
In the windscreen: field of vision of
the Lane Assist system camera. Using the camera located in the windscreen,
the Lane Assist system detects the possible
lines dividing the lanes. When the vehicle in-
voluntarily approaches a dividing line it has
detected, the system notifies the driver with
a
corrective steering movement
.
Thi s move-
ment can be over-regulated at any time.
No warning is produced with the turn signals
activated, given that the Lane Assist system
understands that a lane change is required.
Steering wheel vibration
The following situations cause vibration in
the steering wheel and require the driver to
take active control of driving:
● When the limits of the very nature of the
system are reached. ●
When the maximum rotational torque dur-
ing the corrective steering movement is not
enough to keep the vehicle inside the lane.
● When no lane is detected during the correc-
tive steering movement.
Switching the Lane Assist system on or off
Through the Easy Connect system
● Push the Easy Connect button CAR ●
Push the Setup function button
● Press the function button driver assistance to

Advice
The retract function may not operate properly
in very dirty belts. Make sure that the inertia
reel seat belts are completely dry before al-
lowing them to retract. CAUTION
● Do not remove the seat belts from the vehi-
cle to clean them.
● Do not use chemical cleaning agents on the
seat belts, as this can damage the webbing.
Ensure that the seat belts do not come into
contact with corrosive fluids.
● If you find any damage to the belt webbing,
belt fittings, the belt retractor or the buckle,
the belt in question must be replaced by a
specialised workshop. Intelligent technology
Electro-mechanical steering Electro-mechanical power steering assists
the driver when steering.
Electro-mechanical power steering adapts
electronically to the speed of the car, torque
and t
urnin
g angle.
If the power steering should fail at any time
or the engine is switched off (for instance
when being towed), the car can still be
steered. However, more effort than normal
will be required to turn the steering wheel.
Driver warning lamps and messages  (in red) Faulty steering! To park the vehicle
If the warning lamp remains on and the driver
indication appears, the power steering could
be faulty.
Do not continue driving. Seek specialist as-
s

istance.
 (in yellow) Steering: System fault! You
may continue driving.
If the warning lamp comes on, the steering
could react with more difficultly or more sen-
sitivity than normal. In addition, when driving
in a straight line the steering wheel may be
off-centre. Drive slowly to a specialised workshop and
have the fault repaired.

– Insert the adapter onto the anti-theft wheel
bolt and push it on as far as it will go.
– Insert the wheel brace (vehicle tools) onto
the adapter as far as it will go.
– Remove the wheel bolt ››› page 218. Note
Make a note of the code number of the anti-
theft wheel bolt and keep it in a safe place,
but not in your vehicle. If you need a new
adapter, you can obtain it from the SEAT Offi-
cial Service, indicating the code number. Loosening the wheel bolts
Fig. 185
Wheel: loosen the wheel bolts. –
Insert the box spanner (vehicle tools) onto
the wheel bolt as far as it will go. An adapt-
er is required to unscrew or tighten the an-
ti-theft wheel bolts ››› page 218.
– Turn the wheel bolt approximately one turn
to the left ››› Fig. 185 (arrow). To apply the
r equir
ed torque, hold the wheel brace at
the end. If it is not possible to loosen a
wheel bolt, carefully apply pressure with
one foot on the end of the box spanner.

care not to slip. WARNING
Slightly loosen the wheel bolts (one turn) be-
fore raising the vehicle with the jack*. If not,
an accident may occur. 218

Advice
the wheel condition and hub mounting surfa-
ces. These surfaces must be clean before fit-
ting the wheel. CAUTION
When removing/fitting the wheel, the rim
may hit and damage the brake disc. For this
reason, please take care and get a second
person to assist you. Tyres with compulsory direction of
rotation
A directional tread pattern can be identified
by arrows on the sidewall that point in the di-
rection of rotation. Always observe the direc-
tion of rotation indicated when mounting the
wheel. This is important so that these tyres
can give maximum grip and avoid excessive
noise, tread wear and aquaplaning.
If, exceptionally, it is necessary to mount the
spare wheel* in the opposite direction of ro-
tation, please drive carefully, as in this case
the tyre does not have optimum conditions of
use. This is particularly important when driv-
ing on wet roads.
To benefit from the advantages of tyres with
this type of tread pattern, the defective tyre
should be replaced as soon as possible so
that all tyres again rotate in the correct direc-
tion. After changing a wheel –
On alloy wheels: replace the wheel bolt
caps.
– On plate wheels: replace the wheel hubcap
››› page 217.
– Put the tools and jack back in the luggage
compartment.
– If the replaced wheel does not fit in the
spare wheel housing, store it safely in the
luggage compartment ››› page 114.
– Check the tyre pressure of the newly moun-
ted tyre as soon as possible.
– In vehicles fitted with a tyre pressure indi-
cator, adjust the pressure and store the
reading in the radio/ Easy Connect system*
››› page 212.
– The wheel bolts should be tightened to 120
Nm. Check the torque as soon as possible
with a torque wrench. Meanwhile, drive
carefully.
– Have the flat tyre replaced as quickly as
possible. Tyre repair

Wheel bolts
After the wheels have been changed, the
tightening torque
of the wheel bolts should
be c hec

ked as soon as possible with a torque
wrench ››› . The tightening torque for steel
and alloy wheels is 120 Nm. WARNING
● Check the tyre pressure at least once per
month. Checking the tyre pressure is very im-
portant. If the tyre pressure is too high or too
low, there is an increased danger of accidents
- particularly at high speeds.
● If the tightening torque of the wheel bolts
is too low, they could loosen while the vehi-
cle is in motion. Risk of accident! If the tight-
ening torque is too high, the wheel bolts and
threads can be damaged. Note
We recommend that you ask your Technical
Service for information about appropriate
wheel, tyre and snow chain size. 244
