Emergencies
● If a br
eakdown lorry is used, vehicles with
automatic transmission are only allowed to
be towed with the front wheels suspended.
Towing vehicles with four-wheel drive
(4Drive)
Four-wheel drive vehicles (4Drive) can be
towed using a tow bar or tow rope. If the ve-
hicle is towed with the front or rear axle sus-
pended, the engine must be switched off,
otherwise the transmission may be damaged.
Cases where towing a vehicle is not allowed
● If, due to a fault, the gearbox is out of lubri-
cant
.
● If the vehicle battery is discharged, be-
cau
se the steering remains locked and, if ap-
propriate, the electronic parking brake can-
not be deactivated or the electronic lock of
the steering column released.
● If a distance above 50 km needs to be trav-
ell
ed.
● When, for example, after an accident, the
smooth rot
ation of the wheels or the steering
operation cannot be guaranteed.
When the vehicle is to tow another vehicle:
● Observe legal requirements.
● Keep in mind the instructions in the man-
ual on t
owing vehicles. Note
The vehicle can only be towed if the electron-
ic p

arking brake and the electronic lock of the
steering column are deactivated. If the vehi-
cle has no power supply or there is an electric
system fault, the engine must be tow-started

CAUTION
● The t o
wing eye must always be completely
and firmly tightened. Otherwise, it could be
released while towing and tow-starting.
● If the vehicle is factory-equipped with a
to

wing bracket, it is only allowed to tow with
a tow bar if this has been specially designed
to be installed with a tow hitch. If an unsuita-
ble tow bar is used, both the tow hitch and
the vehicle may be damaged. Instead, a tow
rope should be used. Driving tips for towing
Towing requires some expertise and experi-
enc
e, e

specially when using a tow rope. Both
drivers should be familiar with the difficulties
involved in towing. For this reason, inexper-
ienced drivers should abstain from towing.
During towing, it should be ensured that no
impermissible tractive forces or shocks are
generated. When towing on an unpaved
road, there is always a risk of overloading
and damaging the anchorage points.
During towing, the towing vehicle can signal
the change of direction even with the hazard
warning lights turned on. To do so, at the
same time, the turn signal lever must be op-
erated with ignition switched on. Meanwhile,
the hazard warning lights will go off. When
the turn signal lever is returned to the rest position, the hazard warning lights will be
autom

atically reactivated.
Notes for the driver of the towed vehicle ● Leave the ignition on, so that the steering
is

not blocked, and the electronic parking
brake may be deactivated and the turn sig-
nals and wash/wipe operated.
● More strength is required at the steering
wheel a
s the power steering does not oper-
ate when the engine is switched off.
● You should depress the brake much harder
as
the brake servo does not operate. Avoid
hitting the towing vehicle.
● Bear in mind the information and instruc-
tions
in the manual of the vehicle to be tow-
ed.
Notes for the driver of the towing vehicle
● Accelerate with particular care and caution.
Av
oid sharp manoeuvres.
● Brake earlier than usual and smoothly.
● Bear in mind the information and instruc-
tions
in the manual of the towed vehicle. Fuses and bulbs
F u

ses
Introduction In general, a fuse can be assigned to various
el
ectric

al components. Likewise, an electrical
component can be protected by several
fuses.
Only replace fuses when the cause of the
problem has been solved. If a newly inserted
fuse blows after a short time, you must have
the electrical system checked by a special-
ised workshop as soon as possible. WARNING
The high voltages in the electrical system can
giv e seriou

s electrical shocks, causing burns
and even death!
● Never touch the electrical wiring of the igni-
tion sys
tem.
● Take care not to cause short circuits in the
electric
al system. WARNING
Using unsuitable fuses, repairing fuses or
bridgin g a c

urrent circuit without fuses can
cause a fire and serious injury. 90

Briefly press the starter button ››› Fig. 164 with-
out pressing the accelerator. For the engine to
start there must be a valid key in the vehicle.
After starting the engine, the light of the START ENGINE STOP
button changes to a fixed
light indicating that the engine has started.
4.If the engine does not start, stop and wait for
approx. 1 minute before trying again. If neces-
sary, perform an emergency start ››› page 167.
5.Disconnect the electronic parking brake when
you are about to start driving ››› page 170. WARNING
Never leave the vehicle with the engine run-
nin g, e

specially if a gear or gear range is en-
gaged. The vehicle could then suddenly move
or something strange could happen that
would cause damage, fire or serious injury. WARNING
Cold start sprays could explode or cause a
s ud

den increase in the engine speed.
● Never use sprays to cold start the engine. CAUTION
● The s t

arter motor or the engine may be
damaged if you try to start the engine while
driving or if you restart it immediately after
switching it off.
● If the engine is cold, avoid high engine
speed
s, pushing the engine too hard and rap-
id acceleration.
● Do not start the engine by pushing the ve-
hicl
e or towing it. Unburnt fuel could enter
the catalytic converter and damage it. Note
● Do not w

ait until the engine warms up with
the vehicle stationary; if you have good visi-
bility through the windows, start driving im-
mediately. This helps the engine reach oper-
ating temperature faster and reduces emis-
sions. 168

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

As soon as the driver starts to drive with a
trailer connected electrically to the vehicle, a
message will appear on the instrument panel
display indicating that the blind spot detec-
tor and the rear cross traffic alert are deacti-
vated. Once the trailer has been unhitched
from the vehicle, if you want to use the blind
spot detector and the rear cross traffic alert,
you will have to reactivate them in the corre-
sponding menu.
If the towing hitch is not factory equipped,
then the blind spot detector and the rear
cross traffic alert will have to be deactivated
manually when driving with a trailer.
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. »

Traffic sign detection system* Intr oduction The traffic sign detection system records the
s
t
andard traffic signs in front of the vehicle
with a camera located on the base of the in-
terior mirror and provides information about
speed limits and overtaking prohibitions.
Within its limitations, the system also dis-
plays additional signals, such as time-specif-
ic prohibitions, signs for vehicles towing trail-
ers ›››
page 255 or limitations that only apply
in the event of rain. Even on journeys without signs, the system may display any applicable
speed limits.
In Germany, on motorways and vehicle roads,
besides speed limits and overtaking provi-
sions the system also displays the end of
prohibition signs. The valid speed limit at the
time in other countries is always shown.

Operation
interior rear-view mirror records the traffic
s ign
s in front of the vehicle. After checking
and evaluating the information from the cam-
era, the navigation system and the current
vehicle data, up to three valid traffic signs
are displayed ››› Fig. 198 B in conjunction
with their corresponding additional signs.
The sign that is currently valid for the
driver is shown in the left side of the
screen For example, a maximum speed
limit of 130 km/h (100 mph)
››› Fig. 198 A.
A sign valid only in certain circum-
stances, e.g. 100 km/h (60 mph) is
shown second, together with the addi-
tional rain sign.
If the windscreen wiper is
working while you are driving, the signal
with the additional rain sign will be
shown first, on the left, as it is the one
that is applicable at the time.
A sign valid only with restrictions, e.g.
No overtaking at certain times, will be
displayed third ››› Fig. 198 C.
Speed warning
If the system detects that the permitted
speed is exceeded, it may warn the driver
with a “gong” and visually with a message
on the dash panel display.

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.
