children to play inside or next to it, especially
if the rear lid is open. Children could enter
the luggage compartment, close the rear lid
and become trapped. A locked vehicle can
reach extremely high and low temperatures,
depending on the time of year, thus causing
serious injuries, illness or even death. CAUTION
Before opening or closing the rear lid, make

Lights and visibility
Daytime running lights The daytime running lights consist of individ-
ual lights, int
e
grated in the front headlights.
By connecting the daytime running lights,
these lights are switched on 1)
››› .
The da ytime ru

nning lights switch on every
time the ignition is switched on, if the switch
is in positions  or , according to the level
of exterior lighting.
When the light switch is in position , a
light sensor automatically switches dipped
beam on and off (including the control and
instrument lighting) or the daytime running
lights depending on the level of exterior
lighting. WARNING
● Never driv e w

ith daytime lights if the road
is not well lit due to weather or lighting con-
ditions. Daytime lights do not provide
enough light to illuminate the road properly
or be seen by other road users.
● On vehicles with rear lights with bulbs,
when activating the d
aytime running light
the rear lights are not switched on. A vehicle
which does not have the rear lights on may
not be visible to other drivers in the dark-
ness, in the case of heavy rain or in condi-
tions of poor visibility. Turn signal and main beam lever

Driving
Low brake fluid level
M alf
u
nctions can occur in the brake system if
the brake fluid level is too low. The brake flu-
id level is monitored electronically.
Brake servo
The brake servo increases the pressure you
apply to the brake pedal. It works only when
the engine is running. WARNING
● App ly

the brakes heavily to clean the brake
system only in a suitable traffic situation. Do
not put other road users in danger: there is
risk of causing an accident.
● Ensure the vehicle does not move while in
neutral, when the en
gine is stopped. Failure
to follow this instruction could result in an
accident.
● If the brake fluid loses its viscosity and is
subj
ected to heavy use, vapour bubbles can
form in the brake system. This reduces the ef-
ficiency of the brakes. CAUTION
● Never l et

the brakes “drag” by leaving your
foot on the pedal when it is not necessary to
brake. This overheats the brakes, resulting in
longer stopping distances and greater wear.
● Before driving down a long, steep gradient,
it is
advisable to reduce speed and select a
lower gear. This makes use of engine braking and relieves the brakes. If you still have to
use the br
ak

es, it is better to brake firmly at
intervals than to apply the brakes continu-
ously. Note
● If the br ak

e servo is out of action, for exam-
ple when the car is being towed, you will
have to press the brake pedal considerably
harder than normal to make up for the lack of
servo assistance.
● If you wish to equip the vehicle with acces-
sories s
uch as a front spoiler or wheel covers,
it is important that the flow of air to the front
wheels is not obstructed, otherwise the
brakes can overheat. Hydraulic Brake Assist (HBA)
Electronic stability control (ESC)
The E
SC
help

s 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 .
The ESC includes the anti-lock brake system
(ABS), the hydraulic brake assist (HBA), the traction control system (ASR), electronic dif-
ferenti

al lock (EDS), electronic torque control
(XDS) and tractor-trailer sway mitigation*.
ESC also helps stabilise the vehicle by chang-
ing 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.
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 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 t o ap
pr
oximately 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.
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 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 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 brak
e pedal is greater than the sys- tem’s braking pressure the vehicle will brake
automatic

ally.
● Multi-collision braking will not be available
if ESC
is malfunctioning. WARNING
● The ESC, ABS, ASR, ED S

and the electronic
torque control system cannot exceed the lim-
its imposed by the laws of physics. Always
bear this in mind, especially on wet or slip-
pery roads. If you notice the systems cutting
in, you should reduce your speed immediate-
ly to suit the road and traffic conditions. Do
not be encouraged to take risks by the pres-
ence of more safety systems. If you do, an ac-
cident may occur.
● Please remember that the accident risk al-
way
s 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, EDS and the elec-
tronic torque control system cannot prevent
accidents: risk of accidents!
● Accelerate with caution on slippery surfa-
ces
(for example, icy or snow-covered). De-
spite the control systems, the driven wheels
could spin, affecting the stability of the vehi-
cle: risk of accident! Note
● The ABS and ASR w i

ll only operate correctly
if the four wheels have identical tyres. Any
differences in the rolling radius of the tyres 190

Driving
Driving down hills: in some s it
uation s (on
mountain roads or when towing a trailer or
caravan) it can be advantageous to switch
temporarily to the manual gearbox pro-
gramme so that the gear ratios can be selec-
ted manually to suit the driving conditions
››› .
On l ev
el

ground it is sufficient to move the
selector lever to position P. On slopes, first
engage the parking brake and then put the
selection lever into the P position. This
avoids overloading the locking mechanism
and it will be easier to move the selector lev-
er from position P. WARNING
Observe the safety warnings ›››
in Selector
lev er po
sitions on page 194.
● Never allow the brake to rub and do not use
the brake ped
al too often or for long periods.
Constant braking causes overheating in the
brakes. This could significantly reduce brak-
ing power, increase braking distance or even
result in the total failure of the brake system.
● To avoid rolling back on gradients always
hold the
vehicle with the footbrake or hand-
brake if you have to stop. CAUTION
● If y

ou stop the vehicle on a gradient, do not
attempt to stop it from rolling by depressing
the accelerator when a gear has been selec-
ted. This could cause overheating and dam- age the automatic gearbox. Apply the hand-
brak
e firm

ly or press the brake pedal in order
to prevent the vehicle from rolling back.
● If you allow the car to roll with the selector
lever in po
sition N with the engine switched
off, the automatic gearbox will be damaged as it will not be lubricated.
● In certain driving situations or traffic condi-
tions, suc
h as frequently starting, prolonged
“creeping” of the vehicle or traffic jams with
continuous stoppages, the gearbox could
overheat causing damage! If the warning
lamp  lights up, stop the vehicle as soon as
possible and wait for the gearbox to cool
››› page 200. Kick-down feature
The kick-down feature allows maximum ac-
c
el
er

ation to be reached.
When the accelerator pedal is pressed right
down past the point of resistance at full throt-
tle, the gearbox will shift down to a lower
gear, depending on road speed and engine
speed. The upshift to the next higher gear is
delayed until the engine reaches maximum
rpm. WARNING
Please note that if the road surface is slip-
pery or w

et, the kick-down feature could cause the driving wheels to spin, which could
re
s

ult in skidding. Launch control program

Driving
Run-in and economical driving R u
nnin
g in the engine A new vehicle should be run in over a dis-
tanc
e of

1500 km (1000 miles). For the first
1,000 km the engine speed should not ex-
ceed 2/3 of the maximum permissible engine
speed. In doing so, do not accelerate at full
throttle and do not drive with a trailer! From
1000 to 1500 km (600 to 1000 miles) you
can gradually increase the engine rpm and
road speed.
During its first few hours of running, the in-
ternal friction in the engine is greater than
later on when all the moving parts have bed-
ded down.
How the vehicle is driven for the first 1,500
km influences the future engine perform-
ance. Subsequently, also drive at a moderate
rate, especially when the engine is still cold:
this will lead to less engine wear and tear
and will prolong its useful life.
You should also avoid driving with the engine
speed too low. Change down to a lower gear
when the engine no longer runs “smoothly”.
If the engine revs too much, cut fuel injection
to protect the engine. Environmental compatibility Environmental protection is a top priority in
the des
ign, c

hoice of materials and manufac-
ture of your new SEAT.
Constructive measures to encourage recy-
cling

terrupting the braking process by applying
the brake or pushing the third lever back-
wards ››› page 224.
Driving in tunnels
When driving through tunnels the radar sen-
sor may be limited. Switch off the ACC in tun-
nels.
Narrow or misaligned vehicles
The radar sensor can only detect narrow or
misaligned vehicles when they are within
range ››› Fig. 200 B. This applies particularly
to narrow vehicles such as motorbikes. In
these cases, you should brake as necessary.
Vehicles with special loads and accessories
Special loads and accessories of other vehi-
cles that jut out over the sides, backwards or
over the top may be out of the ACC's range.
Switch off the ACC when driving behind vehi-
cles with special loads and accessories or
when overtaking them. In these cases, you
should brake as necessary. Other vehicles changing lanes
Vehicl
es changing lanes a short distance
away from your own can only be detected
when they are within range of the sensors.
Consequently, the ACC will take longer to re-
act ››› Fig. 201 C. In these cases, you should
brake as necessary.
Stationary vehicles
The ACC does not detect stationary objects
while driving, such as traffic tails or damaged
vehicles.
If a vehicle detected by the ACC turns or
moves over and there is a stationary vehicle
in front of it, the ACC will not react to it
››› Fig. 201 D. In these cases, you should
brake as necessary.
Vehicles driving in the opposite direction
and vehicles crossing your path
The ACC does not react to vehicles approach-
ing from the opposite direction or vehicles
crossing your path.
Metal objects
Metal objects, e.g. rails on the road or sheets
used in road works, can confuse the radar
sensor and cause the ACC to react wrongly. Factors that may affect how the radar sensor
operate
s
If laser sensor operation is impaired, due to
heavy rain, spray, snow or mud, the ACC is
deactivated temporarily. The relevant text
message will appear in the dash panel dis-
play. If necessary clean the SEAT
badge ››› Fig. 196.
When the radar sensor begins to operate
properly again, the ACC will automatically be
available again. The message on the instru-
ment panel screen will switch off and the ACC
will be reactivated again.
ACC operation may be affected by a strong ra-
dar reverse reflection, for example in a closed
car park.
Trailer mode
When driving with trailer the ACC controls
less dynamically.
Overheated brakes
If the brakes overheat, for example after
abrupt braking or in long and steep slopes,
the ACC may be deactivated temporarily. The
relevant text message will appear in the dash
panel display. In this case, adaptive cruise
control cannot be activated.
Adaptive cruise control can be reactivated
once brake temperature has cooled suffi-
ciently. The message will disappear from the
instrument panel display. If the message ACC»
