cally regulates the supplied air temperature
and the blower and air distribution levels.
The system also allows for the effect of sun-
light, so there is no need for manual adjust-
ment.
Automatic operation guarantees maximum

Driving
●
Bef or
e attempting to push-start or tow a ve-
hicle in order to start it, you should first try to
start it using the battery of another vehicle.
Please observe and follow the notes on the
›››  page 71, How to jump start. For the sake of the environment
Do not warm-up the engine by running the
en gine w ith the

vehicle stationary. You
should drive off as soon as you start the en-
gine. This helps the engine reach operating
temperature faster and reduces emissions. Immobiliser “SAFE”*
1)The electronic immobiliser prevents unau-
thori
sed per
son

s from driving the vehicle.
Inside the key there is a chip that deactivates
the electronic immobiliser automatically
when the key is inserted into the ignition.
The electronic immobiliser will be activated
again automatically as soon as you pull the
key out of the ignition lock.
The engine can only be started using a genu-
ine SEAT key with its correct code.
If the following message* is shown on the in-
strument panel display: SAFE, the vehicle
cannot be started. The engine can, however, be started if the
appropri

ate coded SEAT genuine key is used. Note
A perfect operation of the vehicle is ensured
if g enuine

SEAT keys are used. Switching off the engine

itching the engine off, the radiator
fan may run on for up to 10 minutes. It is also
possible that the fan turns itself on once
more if the coolant temperature increases
due to the heat accumulated in the engine
compartment or due to its prolonged expo-
sure to solar radiation. WARNING
● Never sw it

ch the engine off until the vehi-
cle is completely stationary.
● The brake servo works only when the en-
gine is ru
nning. With the engine switched off,
more strength is needed to brake. As normal
brake operation cannot be performed, risk of
accidents and serious injury may exist. ●
The st eerin

g lock can be immediately
blocked once the key is removed from the ig-
nition. The vehicle cannot be steered. Risk of
accident.
● Power-assisted steering does not work
when the engine is
off, and more strength is
needed to turn the wheel.
● If the key is removed from the ignition lock
the steerin
g lock could be engaged and vehi-
cle steering would not work. CAUTION
● When the en gine ha

s been running under a
heavy load for a long period, heat can accu-
mulate in the engine compartment and cause
engine damage. For this reason, idle the en-
gine for approximately 2 minutes before
switching it off.
● If the vehicle is stopped and the Start-Stop
syst
em* switches off the engine, the ignition
remains switched on. Make sure that the igni-
tion is switched off before leaving the vehi-
cle, otherwise the battery could discharge. 1)

Economical and environmentally-

g Fuel consumption, environmental pollution
and w
e
ar t

o the engine, brakes and tyres de-
pends in large part on your driving style. By
adopting an economical driving style and an-
ticipating the traffic situation ahead, you can
easily reduce fuel consumption by 10-15%.
Some tips on how to help you reduce pollu-
tion while saving money are listed below.
Active cylinder management (ACT ®
)*
Depending on vehicle equipment, the active
cylinder management (ACT ®
) may automati-
cally deactivate some of the engine cylinders
if the driving situation does not require too
much power. When it is switched off, no fuel
is injected into these cylinders, hence total
fuel consumption may be reduced. The num- ber of active cylinders can be seen on the in-
strument p

anel display. ›››
 page 38.
Drive anticipating the traffic situation
A vehicle uses most fuel when accelerating.
When you anticipate situations, you have to
brake less often and, thus, accelerate less. If
it is possible, let the vehicle roll with a gear
engaged, for example, if you see a red light
ahead. The braking effect achieved in this
way helps to reduce the wear of brakes and
tyres; emissions and fuel consumption are
reduced to zero (disconnection due to iner-
tia).
Change gear early to save energy
An effective way of saving fuel is to change
up quickly through the gears. Running the
engine at high rpm in the lower gears uses
an unnecessary amount of fuel.
Manual gearbox: shift up from first to second
gear as soon as possible. We recommend
that, whenever possible, you change to a
higher gear upon reaching 2000 rpm. Follow
the “recommended gear” indication that ap-
pears on the instrument panel ››› page 195.
Avoid driving at high speed
We advise you not to drive at the top speed
permitted by the vehicle. Fuel consumption,

Towing bracket device
Anti-theft alarm When the vehicle is locked, the alarm is trig-
ger
ed when the el
ectrical connection be-
tween vehicle and trailer is interrupted.
Always turn off the anti-theft alarm system
before connecting or disconnecting a trailer
››› page 138.
Conditions for the integration of a trailer in
the anti-theft alarm system.
● The vehicle is factory-equipped with an an-
ti-theft al

arm system and a towing bracket
device.
● The trailer is connected electrically to the
tow
ing vehicle by the trailer connector.
● The electrical system of the vehicle and the
trail
er are prepared for operation.
● The vehicle is locked with the ignition key
and the anti-theft al
arm system is activated.CAUTION
For technical reasons, trailers fitted with rear
LED lights ar

e not integrated in the anti-theft
alarm system. Driving tips
Driving with a trailer always requires extra
c
ar e. W

eight distribution
The weight di
stribution of a loaded trailer
with an unladen vehicle is very unfavourable.
However, if this cannot be avoided, drive ex-
tra slowly to allow for the unbalanced weight
distribution.
Speed
The stability of the vehicle and trailer is re-
duced with increasing speed. For this reason,
it is advisable not to drive at the maximum
permissible speed in an unfavourable road,
weather or wind conditions. This applies es-
pecially when driving downhill.
You should always reduce speed immediately
if the trailer shows the slightest sign of snak-
ing. Never try to stop the “snaking” by in-
creasing speed.
Always brake in due course. If the trailer has
an overrun brake, apply the brakes gently at
first and then, firmly. This will prevent the
jerking that can be caused by locking of trail-
er wheels. Select a low gear in due course
before going down a steep downhill. This en-
ables you to use the engine braking to slow
down the vehicle.
Reheating
At very high temperatures and during pro-
longed slopes, driving in a low gear and high
engine speed, always monitor the coolant
temperature gauge ››› page 120. Electronic stability control*
The ESC* sys
tem helps to stabilise the trailer
in case of skidding or rocking.

 page 17
Before starting any work on the engine or in
the engine compartment:
1. Switch off the engine and remove the key from the ignition.
2. Ap

ply the handbrake.
3. Move the gear lever to neutral or the selec- tor lev
er to position P.
4. Wait for the engine to cool down.
5. Keep children away from the vehicle.
6. Raise the bonnet ›››

page 274.
You should not do any work in the engine
compartment unless you know exactly how to
carry out the jobs and have the correct tools!
Have the work carried out by a specialised
workshop if you are uncertain.
All service fluids and consumables, e.g. cool-
ant, engine oil, spark plugs and batteries,
are under constant development. SEAT pro-
vides a constant flow of information to Tech-
nical Services concerning modifications. For
this reason, we recommend you have service fluids and consumables replaced by a Techni-
cal

Service. Please observe the relevant in-
structions ››› page 259. The engine compart-
ment of the vehicle is a hazardous area ››› .
WARNING
All work on the engine or in the engine com-
par tment, e.

g. checking and refilling fluids,
involves the danger of injury and burns, acci-
dents and even fire.
● Never open the bonnet if you see steam,
smoke or coo
lant escaping from the engine
compartment. Otherwise, there is a risk of
sustaining burns. Wait until no more steam or
coolant is emitted, then allow the engine to
cool before carefully opening the bonnet.
● Switch off the engine and remove the key
from the ignition.
● App

ly the handbrake and move the gear
lever t
o neutral or selector lever to position P.
● Keep children away from the vehicle.
● Never touch hot engine parts. There is a
risk of
burns.
● Never spill liquids on a hot engine or on a
hot exh
aust gas system. This is a fire hazard.
● Avoid causing short-circuits in the electri-
cal
system, particularly at the points where
the jump leads are attached ›››
 page 72.
The battery could explode.
● Never touch the radiator fan. It is tempera-
ture c
ontrolled and could start automatically,
even when the engine has been switched off
and the key removed from the ignition! ●
Never c o

ver the engine with additional in-
sulating materials such as a blanket. Risk of
fire!
● Do not unscrew the cap on the coolant ex-
pans
ion tank when the engine is hot. If the
coolant is hot, the cooling system will be
pressurised!
● Protect face, hands and arms by covering
the cap with a l
arge, thick cloth to protect
against escaping coolant and steam.
● Always make sure you have not left any ob-
jects, s
uch as cleaning cloths or tools, in the
engine compartment.
● If you have to work underneath the vehicle,
you mus
t use suitable stands additionally to
support the vehicle, there is a risk of acci-
dent!. A hydraulic jack is insufficient for se-
curing the vehicle and there is a risk of injury.
● If any work has to be performed when the
engine is
started or with the engine running,
there is an additional, potentially fatal, safety
risk from the rotating parts, such as the drive
belts, alternator, radiator fan, etc., and from
the high-voltage ignition system. You should
also observe the following:
– Never touch the electrical wiring of the
ignition system.
– Ensure that jewellery, loose clothing and
long hair do not get trapped in rotating
engine parts. Danger of death. Before
starting any work remove jewellery, tie
back and cover hair, and wear tight-fit-
ting clothes. » 273

 page 59
Top up coolant when the level is below the
MIN (minimum) mark.
Checking coolant level – Park the vehicle in a horizontal position.
– Switch the ignition off.
– Read off the coolant level on coolant ex-
pans

ion tank. When the engine is cold, the
coolant level should be between the marks.
When the engine is hot, it may be slightly
above the upper mark.
Topping up coolant – Wait for the engine to cool down. –
Cov
er the coolant expansion tank cap with
a cloth and carefully unscrew it to the left
››› .
– Top up the coolant only if there is still cool-
ant in the e
xp

ansion tank, otherwise you
could damage the engine. If there is no
coolant in the expansion tank, do not con-
tinue driving. You should obtain professio- nal assistance ››› .
– If there is still some coolant in the expan-
sion t
ank, t

op up to the upper mark.
– Top up with coolant until the level becomes
stab

le.
– Screw the cap back on correctly.
Any lo
ss of coolant fluid normally indicates a
leak in the cooling system. Take the vehicle
straight to a specialised workshop to have
the cooling system examined. If there are no
leaks in the engine cooling system, a loss of
coolant can only occur if the coolant boils
and is forced out of the system as a result of
overheating. WARNING
● The coo lin

g system is under pressure. Do
not unscrew the cap on the coolant expan-
sion tank when the engine is hot: risk of
burns!
● The antifreeze and coolant fluid can be a
health h
azard. Therefore, the antifreeze
should be stored in the original container in a safe place out of reach of children. Failure to
comp
ly

could result in poisoning.
● If working inside the engine compartment,
remember that, ev
en when the ignition is
switched off, the radiator fan may start up au-
tomatically, and therefore there is a risk of in-
jury. WARNING
If there is not enough anti-freeze in the cool-
ant sys

tem, the engine may fail leading to se-
rious damage.
● Please make sure that the percentage of
additiv
e is correct with respect to the lowest
expected ambient temperature in the zone in
which the vehicle is to be used.
● When the outside temperature is very low,
the cool
ant could freeze and the vehicle
would be immobilised. In this case, the heat-
ing would not work either and inadequately
dressed passengers could die of cold. CAUTION
Do not top up the expansion tank with cool-
ant fluid if it

is empty! Air could enter the
cooling system. In this case, stop driving.
Seek specialist assistance. Otherwise, there
is a risk of engine damage. » 279

In the course of time, brake fluid becomes
hygroscopic and absorbs water from the am-
bient air. If the water content in the brake flu-
id is too high, the brake system could cor-
rode. This also considerably reduces the boil-
ing point of the brake fluid. Heavy use of the brakes may then cause a vapour lock which
coul

d impair the braking effect.
Be sure to always use the correct brake fluid.
Only use brake fluid that expressly meets the
VW 501 14 standard.
You can buy VW 501 14 standard brake fluid
in a SEAT dealership or a SEAT Official Serv-
ice. If none is available, use only high-quality
brake fluid that meets DIN ISO 4925 CLASS 4
standards, or USA Standards FMVSS 116 DOT
4.
Using any other kind of brake fluid or one
that is not of a high quality may affect opera-
tion of the brake system and reduce its effec-
tiveness. Never use a brake fluid if the con-
tainer does not state that it complies with VW
501 14, DIN ISO 4925 CLASS 4 standards, or
