.
Indicator for open doors or boot*  This warning lamp lights up if one of the
doors is open.
The warning light
 should go off when all
the doors are closed correctly.
The system also works when the ignition is
switched off. It should disappear approxi-
mately 15 seconds after the vehicle has been
locked.
Electromechanical steering*  For vehicles with power steering, the level of
steering assistance depends on the vehicle's
speed and on the steering angle.
The warning lamp should light up for a few
seconds when the ignition is switched on. It
should go out once the engine is started.
If the battery is disconnected, the indicator
remains lit, even with the engine running. The warning light only goes off after a dis-
tance of approx. 50 m.
There is a fault in the electromechanical
steering system if the lamp does not go out
or lights up while the vehicle is in motion.
The warning lamp may appear in two differ-
ent colours to indicate faults. If the light is
yellow, it indicates a minor fault. If the light is
red, seek assistance from a specialised work-
shop immediately, as the power steering is
not working; in this case you should not keep
driving. Stop the vehicle and seek technical
assistance. The power steering does not work
if the battery is flat or if the engine is off (e.g.
for towing). You should take into account that
you will need considerably more power than
normal to steer the vehicle if the power steer-
ing is not working correctly or at all.
For those vehicles fitted with ESC*, the

Operation
The warning lamp 
has the following
f
unctions:
● It flashes whilst driving when the ASR/ESC
is activated.
● It will light up if there is a fault in the ESC.
● As the ESC operates in conjunction with the
ABS, the ESC light will also come on if a fault
should occur in the ABS.
If the ESC control lamp 
stays on after the
engine is started, this may mean that the
control system has temporarily switched off
the ESC. In this case the ESC can be reactiva-
ted by switching the ignition off and then on
again. If the control lamp goes out, this
means the system is fully functional.
The  lamp provides information about the
disconnection status of the system:
● It stays lit when the ASR is disconnected
when pressing the  switch.
Differential lock fault (EDL)* The EDL operates along with the ABS in vehi-
cles equipped with Electronic Stability Con-
trol (ESC)*.
A malfunction in the EDL is indicated by the
ABS control lamp
. Take the vehicle to a specialised workshop as soon as possible.
For further information on the EDL see
››› page 135, Electronic differential lock
(EDL)* .
T r

action control system (ASR)*  /  The traction control system prevents the driv-
en wheels from spinning when the vehicle is
accelerating.
There are two warning lamps for the traction
control system:
 and . Both warning lamps
light up together when the ignition is switch-
ed on and should turn off after approximately
2 seconds. This is the time taken for the func-
tion check.
The  lamp has the following function:
● It flashes when the ASR is working if the ve-
hicle is moving.
If the system is deactivated or if it has any
fault, the warning lamp will remain lit. The
warning lamp will also light up if a fault
should occur in the ABS because the ASR op-
erates in conjunction with the ABS. For fur-
ther information, see ›››
page 137. The
 lamp provides information about the
di

sconnection status of the system:
● It stays lit when the ASR is disconnected
when pressing the ASR OFF switch.
By pressing it again, the ASR function is reac-
tivated and the warning lamp switched off.

the display
The system runs a check on certain compo-
nents and functions when the ignition is
switched on and while the vehicle is moving.
Functional faults are indicated by symbols
with warning or information messages in the
display. An audible warning is given in cer-
tain cases.
Warning symbols
There are red warning symbols (priority 1)
and yellow warning symbols (priority 2).
Information text
In addition to warning messages given on a
fault, you will receive information in the dis-
play on procedures or will be asked to carry
out certain tasks. Note
In the case of screens without warning or in-
formation messages, faults are indicated ex-
clusively by the control lamps. Warning messages, Priority 1 (red)
If one of these faults occurs, the warning
lamp will light up or flash and will be accom-
panied by
three audible warnings. This is a
danger warning. Stop the vehicle and switch
off the en
gine. Check the fault and correct it.
Obtain professional assistance if necessary.
If several priority 1 faults are detected at the
same time, the symbols will be displayed one
after the other for about 2 seconds at a time
and will continue until the fault is corrected.
No menus will be shown in the display for the
duration of a priority 1 warning message.

Operation
tempt you into taking any risks when driving.
Failure to follow this instruction could result
in an accident.
●
The braking capability of your vehicle is
limited by the tyres' grip. Vehicle behaviour
is no different from a vehicle without four-
wheel drive. So do not be tempted to drive
too fast on icy or slippery roads just because
the vehicle still has good acceleration in
these conditions. Failure to do so could result
in an accident.
● On wet roads bear in mind that the front
wheels may lose contact with the road and
start to float (aquaplaning) if the vehicle is
driven too fast. If this should happen, there
will be no sudden increase in engine speed
when aquaplaning begins to warn the driver,
as with a front-wheel drive vehicle. For this
reason and for that mentioned above, always
choose a driving speed suitable for the road
conditions. Failure to follow this instruction
could result in an accident. Driving with LPG*

Driving
WARNING
● The ignition key must NOT be removed from
the lock until the vehicle comes to a stand-
still. Otherwise, the steering could be imme-
diately blocked- Risk of accident!
● Always remove the key from the ignition
when leaving the vehicle, even if only for a
short period. This is especially important if
children or disabled people are left alone in
the vehicle. They could accidentally start the
engine or work electrical equipment such as
the electric windows, resulting in an acci-
dent.
● Unsupervised use of the key could start the
engine or any electrical system, such as the
electric windows. This could result in serious
injury. CAUTION
The starter motor will only work when the en-
gine is stopped (ignition key position 2 ).
Electronic immobiliser
The electronic immobiliser prevents unau-
thorised persons 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.
Note
A perfect operation of the vehicle is ensured
if genuine SEAT keys are used. Starting petrol engines
The engine can only be started using a genu-
ine SEAT key with its correct code.
– Move the gearbox lever to the neutral posi-
tion and depress the clutch pedal thor-
oughly and hold it in this position for the
starter to turn the engine on.
– Turn the ignition key to the starting posi-
tion ›››
page 120 .
– Let
go of the ignition key as soon as the en-
gine starts; the starter motor must not run
on with the engine.
After starting a very hot engine, you may
need to slightly press down the accelerator.
When starting a cold engine, it may be a little
noisy for the first few seconds until oil pres-
sure has built up in the hydraulic valve com-
pensators. This is quite normal, and no cause
for concern. If the engine does not start immediately,
switch the starter off after 10 seconds and try
again after half a minute. If the engine still
does not start, the fuel pump fuse should be
checked
››› page 196, Fuses. WARNING
● Never start or run the engine in unventila-
ted or closed rooms. The exhaust gases con-
tain carbon monoxide, an odourless and col-
ourless poisonous gas. Risk of fatal acci-
dents. Carbon monoxide can cause loss of
consciousness and result in death.
● Never leave the vehicle unattended if the
engine is running.
● Never use “cold start sprays”, they could
explode or cause the engine to run at high
revs. Risk of injury. CAUTION
● When the engine is cold, you should avoid
high engine speeds, driving at full throttle
and over-loading the engine. Risk of engine
damage.
● The vehicle should not be pushed or towed
more than 50 metres to start the engine. Un-
burnt fuel could enter the catalytic converter
and damage it.
● Before 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.

Driving
Some tips on how to help you reduce pollu-
tion while saving money are listed below.
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
ahe a
d. 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 47.
Avoid driving at high speed
We advise you not to drive at the top speed
permitted by the vehicle. Fuel consumption,
exhaust emissions and noise levels all in- crease very rapidly at higher speeds. Driving
at moderate speeds will help to save fuel.
Avoid idling
It is worthwhile switching off the engine
when waiting in a traffic jam, at level cross-
ings or at traffic lights with a long red phase.
The fuel saved after only 30 - 40 seconds is
greater than the amount of fuel needed to re-
start the engine.
The engine takes a long time to warm up
when it is idling. Mechanical wear and pollu-
tant emissions are also especially high dur-
ing this initial warm-up phase. It is therefore
best to drive off immediately after starting
the engine. Avoid running the engine at high
speed.
Periodic maintenance
Periodic maintenance work guarantees that,
before beginning a journey, you will not con-
sume more than the required amount of fuel.
A well-serviced engine gives you the benefit
of
improved fuel efficiency as well as maxi-
mum reliability and an enhanced resale val-
ue.
A badly serviced engine can consume up to
10% more fuel than necessary.
Avoid short journeys
To reduce the consumption and emission of
polluting exhaust gases, the engine and the exhaust gas filtration systems should reach
the optimum operating temperature.
With the en

gine cold, fuel consumption is
proportionally higher. The engine does not
warm up and fuel consumption does not nor-
malise until having driven approximately four
kilometres. This is why we recommend avoid-
ing short trips whenever possible.
Maintain the correct tyre pressures
Bear in mind that keeping the tyres at an ad-
equate pressure saves fuel. If the tyre pres-
sure is just one bar (14.5 psi / 100 kPa) too
low, fuel consumption can increase by as
much as 5%. Due to the greater rolling resist-
ance, under-inflation also increases tyre wear
and impairs handling.
The tyre pressures should always be checked
when the tyres are cold.
Do not u

se winter tyres
all year round as they
increase fuel consumption by up to 10%.
Avoid unnecessary weight
Given that every kilo of extra weight
will in-
crease the fuel consumption, it is advisable
to always check the luggage compartment to
make sure that no unnecessary loads are be-
ing transported.
A roof rack is often left in place for the sake
of convenience, even when it is no longer
needed. At a speed of 100 km/h (62 mph) »

Towing bracket device
Tyre pressure
Set tyre pressure to the maximum permissi-
ble pressure shown on the sticker on the in-
side of the fuel tank flap. Set the tyre pres-
sure of the trailer tyres in accordance with the
trailer manufacturer's recommendations.
Exterior mirrors
Check whether you can see enough of the
road behind the trailer with the standard rear
vision mirrors. If this is not the case, you
should have additional exterior mirrors fitted.
Both exterior mirrors should be mounted on
hinged extension brackets. Adjust the mirrors
to give sufficient vision to the rear. WARNING
Never transport people in a trailer. This could
result in fatal accidents. Note
● Towing a trailer places additional demands
on the vehicle. We recommend additional
services between the normal inspection inter-
vals if the vehicle is used frequently for tow-
ing a trailer.
● Find out whether special regulations apply
to towing a trailer in your country. Ball coupling of towing bracket*
Depending on the model version, the spheri-
cal head on the trailer hook may be stored in
the tool box.
The ball coupling is provided with instruc-
tions on fitting and removing the ball cou-
pling of the towing bracket.
WARNING
The towing bracket ball coupling must be
stored securely in the luggage compartment
to prevent them being flung through the vehi-
cle and causing injury. Note
● By law, the ball coupling must be removed
if a trailer is not being towed if it obscures
the number plate. Driving tips
Driving with a trailer always requires extra
care.
Weight distribution
The weight distribution 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-
c r
easing 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 31.
Electronic Stability Control*
The ESC* system helps to stabilise the trailer
in case of skidding or rocking.
