In vehicles that do not have the correspond-
ing menu, this function can be deactivated in
a specialised workshop. WARNING
Improper or lack of use of the turn signals, or
f or

getting to deactivate them can confuse
other road users. This could result in a seri-
ous accident.
● Always give warning when you are going to
ch
ange lane, overtake or when turning, acti-
vating the turn signal in good time.
● As soon as you have finished changing
lane, o
vertaking or turning, switch the turn
signal off. WARNING
Incorrect use of the headlights may cause ac-
c ident

s and serious injury, as the main beam
may distract or dazzle other drivers. Note
● If the c

onvenience turn signals are operat-
ing (three flashes) and the other convenience
turn signals are switched on, the active part
stops flashing and only flashes once in the
new part selected.
● The turn signal only works when the igni-
tion is
switched on. The hazard warning
lights also work when the ignition is switch-
ed off.
● If a trailer turn signal malfunctions, the
contr
ol lamp will stop flashing (trailer turn
signals) and the vehicle turn signal will flash
at double speed.
● The main beam he
adlights can only be
switched on if the dipped beam headlights
are already on.
● In cold or damp weather conditions, the
hea
dlights, tail lights and turn signals may
mist up inside temporarily. This is normal and
in no way effects the useful life of the vehicle

Instrument panel lighting
With the ignition on and without light activa-
tion, the instrument panel lighting remains
activated in daytime light conditions. The
lighting is reduced as the exterior light di-
minishes. In some cases, e.g. when driving
through a tunnel without the  function
active, the instrument panel lighting may
even switch off. The objective of this function
is to provide the driver with a visual indica-
tion that he or she should activate the dip-
ped beam. WARNING
Heavy objects in the vehicle may mean that
the he a

dlights dazzle and distract other driv-
ers. This could result in a serious accident.
● Adjust the light beam to the vehicle load

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

ake 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
such 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. Front assist system
Electronic stability control (ESC)
The E
SC

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 .
The ESC includes the anti-lock brake system
(ABS), the front assist system (HBA), the trac-
tion control system (ASR), electronic differen-
tial 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.
Front assist system (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.
El
ectronic 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.
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 »

Operation
When accelerating, the gearbox automatical-
ly shif
ts up into the next gear shortly before
the maximum engine speed is reached.
If you select a lower gear, the automatic gear-
box will not shift down until there is no risk of
over-revving the engine.
When the kick-down feature is used, the
gearbox shifts down to a lower gear, depend-
ing on road speed and engine speed.
Driving tips The gearbox changes gear ratios automatical-
ly
a

s the vehicle moves.
The engine can only start with the selector
lever in position P or N. At low temperatures,
below -10°C (50°F), the engine can only start
with the selector lever in position P.
Starting the vehicle
– Press and hold the brake pedal.
– Press and hold the interlock button (the
butt

on on the selector lever handle), move
the selector lever to the desired position,
for instance D ›››
page 177, and release the
interlock button.
– Wait for the gearbox to engage the gear (a
slight

movement can be felt).
– Release the brake and press the accelerator
››
› . Stopping briefly
– Apply the foot brake to hold the vehicle
briefly when s

tationary (for instance at traf-
fic lights). Do not press the accelerator.
Stopping/Parking
If the driver door is opened and the selector
lever is not in position P, the vehicle could
move. The driver message will be:  Gear
change: selector lever in the
drive position! . Additionally, a buzzer
will sound.
– Press and hold the brake pedal ››
› .
– Apply the handbrake.
– Move the selector lever to position P.
Ho l

ding the car on a hill
– Always apply the brake pedal firmly to pre-
v
ent the vehicle from “moving backwards;
if necessary, apply the handbrake” ››› .
Do not tr y

to stop the vehicle “rolling back”
by increasing the engine speed when a
gear is engaged (pressing the accelerator)
››› .
St ar

ting off uphill
– Apply the handbrake.
– Once you have engaged a gear press the
acc

elerator carefully and disengage the
handbrake. Driving down hills: in some sit

uations (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
l ev
er positions on page 177.
● Never allow the brake to rub and do not use
the brak
e pedal 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
hol
d the vehicle with the footbrake or hand-
brake if you have to stop. CAUTION
● If

you 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 180

Run-in and economical driving Ru
nning-in the engine A new vehicle should be run in over a dis-
t
anc

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 t

oo 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 de
s

ign, choice of materials and manufac-
ture of your new SEAT.

There is a danger of rear collision when the
minimum di s

tance to the vehicle in front is
exceeded and the speed difference between both vehicles is so great that a speed reduc-
tion b
y

the brake pedal should be applied immedi-
ately.
● The ACC may not be able to detect all situa-
tions
properly.
● “Stepping” on the accelerator may cause
the AC
C not to intervene in braking. Driver
braking will have priority over intervention by
the speed control or adaptive cruise control.

emergency braking and
pedestrian monitoring*
Introduction The Front Assist system including City emer-
g
ency

braking and pedestrian monitoring can
help avoid collisions.
The Front Assist system may warn the driver,
within the constraints of the system, of im-
pending collisions, prepare the vehicle for
emergency braking in case of danger, provide
support during braking and apply automatic
braking.
The City emergency braking and pedestrian
monitoring functions are an integral part of
the Front Assist system.
The Front Assist is not a replacement for
driver awareness.
Distance warning
If the system detects that safety is endan-
gered by the proximity of the vehicle in front,
it may warn the driver by means of a message
on the instrument panel when driving at a
speed of between approximately 60 km/h
(37 mph) and 250 km/h (156 mph)
››› Fig. 184.
The warning moment varies depending on
the traffic situation and driver behaviour. Advance warning
If
the sy

stem detects a possible collision with
the vehicle in front, it may warn the driver by
means of an audible warning and an indica-
tion on the instrument panel when driving at
a speed of between approximately 30 km/h
(18 mph) and 250 km/h (156 mph)
››› Fig. 184.
The warning moment varies depending on
the traffic situation and driver behaviour. At
the same time, the vehicle will prepare for a
possible emergency braking ››› .
C ritic

al warning
If the driver fails to react to the advance
warning, the system may actively intervene in
the brakes when driving at a speed of be-
tween approximately 30 km/h (18 mph) and
250 km/h (156 mph), generating a brief jolt
to warn of the imminent collision.
Automatic braking
If the driver also fails to react to the advance
warning, the system may brake the vehicle
automatically, by progressively increasing
braking effect driving at a speed of between
approximately 4 km/h (2.5 mph) and
250 km/h (156 mph). By reducing speed in
case of a possible collision, the system may
contribute to reducing the consequences of
an accident. »

SEAT Drive Profile*
Introduction The SEAT Drive Profile enables the driver to
c
hoo

se between four profiles or modes, Eco,
Normal , Sport and Individual , that
modify the behaviour of various vehicle func-
tions, providing different driving experiences. In addition, the 4Drive version features the
Offroad and Snow profi

les.
The Individual profile can be configured
according to personal preferences. The other
profiles have a fixed configuration.
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 the Eco profile is
selected, the Start-Stop function is automati-
cally 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 profile activates the in-
ertia function, enabling consumption to be
further reduced.
In manual gearbox vehicles, the Eco profile
causes the gear change recommendation in-
dications that appear on the dash panel to
vary, facilitating more efficient driving. »

130 km (80 mph). If it is adjusted to a speed
greater than that which is permitted in the
country in question for driving with a trailer,
the system automatically displays the usual
speed limits, e.g. in Germany 80 km/h
(50 mph).
If the speed warning for the trailer is deacti-
vated, the system displays the speed limits
as if there were no trailer hitched. Limited operation
The traffic

sign detection system has certain
limitations. The following cases may lead the
system to operate with limitations or not at
all:
● In the case of poor visibility, e.g. in snow,
rain, f
og or intense mist.
● In cases of dazzling, e.g. caused by head-
on traffic
or by the sun.
● When driving at high speeds.
● If the camera is covered or dirty.
● If the traffic signs are out of the camera's
field of
vision.
● If the traffic signs are partially or totally
co
vered, e.g. by trees, snow, dirt or other ve-
hicles.
● In the case of traffic signs that do not fulfil
the re
gulations.
● In the case of damaged or bent traffic
sign
s.
● In the case of variable messages on over-
hea
d or gantry signs (LED-based variable traf-
fic signs or other lighting units).
● If the maps on the navigation system are
not up-t
o-date.
● In the case of adhesives affixed to vehicles
that
depict traffic signs, e.g. speed limits on
lorries.
