WARNING
You should switch on the ESC Sport mode on-
ly if the tr

affic conditions and your driving
ability allow you to do so safely: risk of skid-
ding!
● With ESC in Sport mode, the stabilising
function w
ill be limited to allow for a sportier
drive. The driving wheels could spin and the
vehicle could skid. Note
If the ASR is disconnected or the ESC’s Sport
mode is sel

ected, cruise control* will be
switched off. Electronic Stability Control (ESC)*
This Electronic Stability System reduces the
ri
sk
of

skidding and improves the vehicle's
stability and ability to hold the road.
The Electronic Stability Control (ESC) contains
the electronic differential lock (EDL) and the
traction control system (ASR). The ESC works
together with the ABS. Both control lamps
will light up if the ESC or ABS systems are
faulty.
The ESC system is started automatically
when the engine is started. The ESC system is always active and cannot
be switc

hed off. With the Easy Connect sys-
tem it is only possible to deactivate the ASR
or else select Sport mode.
The ASR can be deactivated when wheel spin
is desirable ››› page 172.
For example:
● When driving with snow chains.
● When driving in deep snow or on loose sur-
face
s.
● When the vehicle is stuck, to rock it back-
ward
s and forwards.
Press the button to switch the ASR back on
when you no longer need wheel spin.
Electronic Stability Control (ESC)*
The ESC reduces the risk of skidding by brak-
ing the wheels individually.
The system uses the steering wheel angle
and road speed to calculate the changes of
direction desired by the driver, and constant-
ly compares them with the actual behaviour
of the vehicle. When irregularities occur, for
example, if the vehicle begins to skid, the
ESC brakes the appropriate wheel automati-
cally.
The forces acting on the braked wheel bring
the vehicle back to a stable condition. If the
vehicle tends to oversteer (the rear end slides out), the system will act on the front
wheel on the outside of

the turn. WARNING
● Do not f or

get that the electronic stability
control ESC cannot defy the laws of physics.
This should be kept in mind, particularly on
slippery and wet roads and when towing a
trailer.
● Always adapt your driving style to suit the
condition of the r
oads and the traffic situa-
tion. The greater safety provided by the ESC
should not encourage you to run any risks. CAUTION
● To en s

ure that the ESC works correctly, all
four wheels must be fitted with the same
tyres. Any differences in the rolling radius of
the tyres can cause the system to reduce en-
gine power when this is not desired.
● Any modifications made to the vehicle (for
examp
le, to the engine, brake system, run-
ning gear or to the combination of wheels
and tyres) may affect the operation of the
ABS, EDL, ESC and ASR. Electronic differential lock (EDS)*
EDL helps the vehicle to start moving, accel-
er
at
e and c

limb a gradient in slippery condi-
tions where this may otherwise be difficult or
even impossible.

pressure to this wheel. The driver is made
a w
ar
e of this control process by a pulsating
of the brake pedal and audible noise. This is
a deliberate warning to the driver that one or
more of the wheels is tending to lock and the
ABS control function has intervened. In this
situation it is important to keep the brake
pedal fully depressed so the ABS can regu-
late the brake application. Do not “pump”.
If you brake hard on a slippery road surface,
the best possible control is retained as the
wheels do not lock.
However, ABS will not necessarily guarantee
shorter braking distances in all conditions.
Braking distance could even be further if you
brake on gravel or on fresh snow on a slip-
pery surface. WARNING
● The anti-lock br

ake system cannot defy the
laws of physics. Slippery and wet roads are
dangerous even with ABS! If you notice that
the ABS is working (to counteract locked
wheels under braking), you should reduce
speed immediately to suit the road and traffic
conditions. Do not let the extra safety fea-
tures tempt you into taking any risks when
driving.
● The effectiveness of ABS is also determined
by the ty
res fitted ››› page 212.
● If the running gear or brake system is modi-
fied, the effectivene
ss of the ABS could be se-
verely limited. Traction control system (ASR)*
The traction control system prevents the driv-
en wheels
fr

om spinning when the vehicle is
accelerating. This system always includes
ABS.
Description and operation of the traction
control system during acceleration (ASR
On front-wheel drive vehicles, the ASR sys-
tem intervenes, reducing engine power and
preventing the driven wheels from slipping
during acceleration. The system works in the
entire speed range in conjunction with ABS.
If a failure occurs in the ABS, the ASR will al-
so stop working.
TCS helps the car to start moving, accelerate
and climb a gradient in slippery conditions
where this may otherwise be difficult or even
impossible.
The ASR automatically switches on when the
engine is started. If necessary, it could be
connected or disconnected by means of the
Easy Connect system.
When the ASR is off, the warning lamp lights
up . The ASR should normally be left on.
Only in exceptional circumstances, when
wheel spin is required, can they be turned off
using the ESC button, for example:
● With compact temporary spare wheel.
● When using the snow chains. ●
When drivin g in deep s

now or on soft ter-
rain.
● When the vehicle is bogged-down, to free it
“by r
ocking it.”
The ASR should be switched on again as
soon as possible. WARNING
● Remember th at

not even the ASR can defy
the laws of physics. This should be kept in
mind, particularly on slippery and wet roads
and when towing a trailer.
● Always adapt your driving style to suit the
condition of the r
oads and the traffic situa-
tion. The greater safety provided by the ASR
should not encourage you to run any risks. CAUTION
● To en s

ure that the ASR works correctly,
identical tyres should be fitted on all four
wheels. Any differences in the rolling radius
of the tyres can cause the system to reduce
engine power when this is not desired.
● Any modifications made to the vehicle (for
examp
le, to the engine, brake system, run-
ning gear or to the combination of wheels
and tyres) may affect the operation of the
ABS and ASR. 172

Wheels
for your model. Failure to do so could impair
vehic
l
e handling. Risk of accident.
● Avoid running the vehicle on tyres that are
more than 6
years old. If you have no alterna-
tive, you should drive slowly and with extra
care at all times.
● Never use old tyres or those with an un-
known “his
tory of use”.
● If wheel trims are retrofitted, you must en-
sure th
at the flow of air to the brakes is not
restricted. This could cause the brake system
to overheat.
● All four wheels must be fitted with radial
tyre
s of the same type, size (rolling circumfer-
ence) and the same tread pattern. For the sake of the environment
Old tyres must be disposed of according to
the la w

s in the country concerned. Note
● For t ec

hnical reasons, it is not generally
possible to use the wheels from other vehi-
cles. This can also apply to wheels of the
same model. The use of wheels or tyres
which have not been approved by SEAT for
use with your model may invalidate the vehi-
cle's type approval for use on public roads.
● If the spare tyre is not the same as the
tyre
s that are mounted on the vehicle (e.g.
winter tyres) you should only use the spare
tyre for a short period of time and drive with extra care. Refit the normal road wheel as
soon as
po

ssible. Wheel bolts
The design of wheel bolts is matched to the
rims. If diff
er

ent wheel rims are fitted, the
correct wheel bolts with the right length and
correctly shaped bolt heads must be used.
This ensures that wheels are fitted securely
and that the brake system functions correctly.
In certain circumstances, you should not use
wheel bolts from a different vehicle, even if it
is the same model ››› page 190. WARNING
If the wheel bolts are not tightened correctly,
the wheel c ou

ld become loose while driving.
Risk of accident.
● The wheel bolts must be clean and turn
eas
ily. Never apply grease or oil to them.
● Use only wheel bolts which belong to the
wheel.
● If the pr

escribed torque of the wheel bolts
is t
oo low, they could loosen whilst 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. CAUTION
The prescribed tightening torque for wheel
bolt s

for steel and alloy wheels is 120 Nm. Winter service
Wint er ty

res In winter conditions winter tyres will consid-
erab
ly

improve the vehicle's handling. The
design of summer tyres (width, rubber com-
pound, tread pattern) gives less grip on ice
and snow.
Winter tyres must be inflated to a pressure of
0.2 bar (2.9 psi/20 kPa) higher than the pres-
sures specified for summer tyres (see sticker
on fuel tank flap).
Winter tyres must be fitted on all four wheels.
Information on permitted winter tyre sizes
can be found in the vehicle's registration
documentation. Use only radial winter tyres.
All tyre sizes listed in the vehicle documenta-
tion also apply to winter tyres.
Winter tyres lose their effectiveness when the
tread is worn down to a depth of 4 mm.
The speed rating code ›››
page 214, New
tyres and wheels determines the following
speed limits for winter tyres: ››› max. 160 km/h (99 mph)
