Engine oil level correct
If the  symbol flashes and the engine oil level is correct, obtain profes-
sional assistance. Do not drive on! Do not continue to run the engine, even
at idle speed .
Note
The oil pressure warning lamp  is not an indicator for the oil level. The oil
level should therefore be checked regularly, preferably every time you fill
the tank. 

Yellow symbols are accompanied by one warning buzzer. The function indi-
cated should be checked as soon as possible. If several Priority 2 faults are
detected at the same time, the symbols are displayed one after the other for
about 2 seconds at a time. 
Brake light failure 
This warning light will appear on the upper part of the display if any of the
brake lights has failed. A text message in the central part of the display indi-
cates which brake light has failed (left or right). 
Fuel level low 
When this symbol  comes on for the first time, there are about 8 to 10 li-
tres of fuel left in the tank. You should fill up as soon as possible
⇒  page 222. 
Engine speed governing 
Max. engine speed XXXX rpm
There is a fault in the engine management. In addition, the warning lamp 
on the instrument panel will light up. The engine speed will be governed to
the speed displayed in the driver information system. Please ensure that
the engine speed does not exceed the speed shown (for example, when
changing down a gear).
Take the vehicle to a qualified workshop immediately to have the fault re-
paired. Checking the engine oil level

If the  symbol lights up, please check the engine oil level as soon as pos-
sible ⇒ page 229. Top up the oil at the next opportunity ⇒ page 230.
Engine oil sensor defective* 
If the  symbol lights up, take the vehicle to a qualified workshop and
have the oil level sensor checked. Until then it is advisable to check the oil
level every time you fill up with fuel ⇒ page 229. 
Diesel particulate filter obstructed 
If the symbol  lights up, you can contribute towards automatic filter
cleaning by driving in the right manner. To do this, drive about 15 minutes
in 4th or 5th gear (automatic gearbox: S gear range) at a speed of 60 km/h,
with the engine running at approximately 2000 rpm. The increase in temper-
ature will burn off any soot in the filter. When cleaning is successful, the
symbol switches off.
If the symbol  does not turn off, or the three lamps turn on (particulate
filter , emission control system fault  and heaters ), take the vehicle
to a qualified workshop to repair the fault.
For further information on the diesel particulate filter, see ⇒ page 198.
WARNING
It is essential that you adjust your speed to suit the weather, road, ter-
rain and traffic conditions. The recommended driving speed must never
lead to the driver disregarding the traffic regulations.

176Driving
Handbrake on
The handbrake warning switches on after driving for 3 seconds at speeds
above 5 km/h.
The handbrake warning lamp  lights up when the handbrake is applied
with the ignition on.
WARNING
Please note that the handbrake should be released all the way. If it is on-
ly partially released, this will cause rear brakes overheating, which can
impair the function of the brake system and could lead to an accident.
CAUTION
Once the vehicle has come to a standstill, always apply the handbrake firm-
ly and then, on a manual gearbox, engage a gear, or select P on an auto-
matic. 
Parking
The following points will ensure there is no risk of the vehi-
cle rolling away accidentally after it is parked:
– Use the foot brake to stop the vehicle.
– Apply the handbrake firmly.
– Switch the engine off.
– On a manual gearbox engage 1st gear or on an automatic move
the selector lever to P ⇒ 
. When parking on slopes:
Turn the steering wheel so that the, if the vehicle moves, it will do so to-
wards the curb.
WARNING
● Do not leave anyone (especially children) in the vehicle when it is
locked. Locked doors could delay assistance in an emergency, potentially
putting lives at risk.
● Never leave children unsupervised in the vehicle. They could release
e.g. the handbrake or gear lever, moving the vehicle and causing an acci-
dent.

Parking aid acoustic system General notes
Various systems are available to help you when parking or manoeuvring in
tight spaces, depending on the equipment fitted on your vehicle.
The SEAT Parking System gives an acoustic warning if there are any obsta-
cles behind your vehicle ⇒ page 177.
When you are parking, SEAT Parking System Plus warns you acoustically
and optically about obstacles in front of and behind the vehicle
⇒ page 177.
Note
To ensure the acoustic parking aid works properly, the sensors must be kept
clean and free of snow and ice. 

Electronic Stability Programme (ESP) General notes
The Electronic Stability Programme increases the vehicle's
stability on the road.
Fig. 160 Centre console
with ESP switch
The ESP is designed to increase the degree of control in situations where
the vehicle approaches the limits of adhesion, especially when accelerating
and cornering. It reduces the risk of skidding and improves stability in all
road conditions. The system is active across the entire speed range. The anti-lock brake system (ABS), the electronic differential lock (EDL) and
the traction control system (TCS) are all integrated into the Electronic Stabil-
ity Programme.
How it works
The ESP control unit processes data from the three integrated systems. It al-
so processes additional inputs provided by other high-precision sensors.
These register the vehicle's rotation about the vertical axis (yaw rate), later-
al acceleration, brake pressure and steering wheel angle.
The system uses the steering wheel angle and road speed to calculate the
changes of direction desired by the driver, and constantly compares them
with the actual behaviour of the vehicle. If the desired course is not being
maintained (for instance, if the vehicle is starting to skid), then the ESP
compensates automatically by braking the appropriate wheel.
The forces acting on the braked wheel bring the vehicle back to a stable
condition. If the vehicle
over swerves (tendency of the rear to leave the
road), the brakes will act on the front wheel facing the outside of the bend.
If the vehicle under swerves (tendency to leave the bend), the braking force
is applied to the rear wheel facing the inside of the bend.
The ESP works in conjunction with the ABS ⇒ page 191. If a malfunction
should occur in the ABS, the ESP will also stop working.
Deactivating
The ESP is activated automatically when the engine is started and performs
a self-test routine. 

192Intelligent technology
Brake assist system
The brake assist system helps the driver to achieve optimum
braking effect.
The brake assist system helps to increase braking power and thus to ach-
ieve a shorter stopping distance. If the driver presses the brake pedal very
quickly, the brake assist system automatically boosts the braking force to
the maximum level, up to the point where the anti-lock brake function (ABS)
intervenes to stop the wheels from locking. You should then keep the brake
pedal pressed until the vehicle has braked to the required speed. The brake
assist system switches itself off as soon as you release the brake pedal.
The brake assist system will not be operative if there is a malfunction in the
ABS or the ESP.
WARNING
Please remember that the accident risk always increases if you drive too
fast, especially in corners or on a slippery road, or if you follow too close
behind the vehicle in front of you. An increased accident risk cannot be
compensated even by the brake assist system. Risk of accident.

Electronic differential lock (EDL)
The electronic differential lock prevents the loss of traction
caused if one wheel starts spinning. General notes
The electronic differential lock (EDL) helps the vehicle to start moving, ac-
celerate and climb a gradient in slippery conditions where this may other-
wise be difficult or even impossible. How it works
The EDL works automatically, without the driver's involvement. With the aid
of the ABS sensors, the system monitors the rotational speed of the drive
wheels
⇒ page 191. If a considerable difference in revs is detected (approx.
100 rpm) in the speed of the drive wheels, e.g. when only one part of the
surface supporting the wheels is slippery, the system applies the brake to
slow down the skidding wheel so that more of the power is directed to the
other wheels. The systems works up to a speed of approx. 80 km/h. The
system will make noise while it is working.
Starting the vehicle
If one wheel has less grip and starts spinning (for instance, if one of the
drive wheels is on ice), keep pressing the accelerator gradually until the ve-
hicle starts moving.
Overheating of the brakes
To prevent the brake disk of the braked wheel from overheating, the EDL
cuts out automatically if subjected to excessive loads. In this case, the vehi-
cle will continue to run and will have the same running properties as those
of another without EDL.
The EDL will switch on again automatically when the brake has cooled
down.
WARNING
● When accelerating on a uniformly slippery surface (for instance all
four wheels on ice or snow), press the accelerator gradually and careful-
ly. Despite EDL, the drive wheels may otherwise start to spin. This could
impair the vehicle's stability. Risk of accident.
● Even with EDL, you should always adjust your speed to suit the road
and traffic conditions. Do not let the extra safety features tempt you into
taking any risks when driving. Failure to do so could result in an accident. 

193
Intelligent technology
Note
If the ABS warning lamp lights up, this can also mean there is a fault in the
EDL. Take the vehicle to a specialised workshop as soon as possible. 
Traction control system (TCS)
The traction control system prevents the drive wheels from
spinning when the vehicle is accelerating. General notes
The traction control system (TCS) is one of the functions incorporated in the
Electronic Stability Programme (ESP).
The traction control system (TCS) helps the vehicle to start moving, acceler-
ate or climb a gradient in slippery conditions where this may otherwise be
difficult or even impossible.
How it works
The TCS acts automatically, without the driver's intervention. With the aid of
the ABS sensors ⇒ page 191, the TCS monitors the speed of the drive
wheels. If the wheels start to spin, the engine speed is reduced automati-
cally to match the amount of grip available. The system is active across the
entire speed range.
The TCS works in conjunction with the ABS. If a malfunction occurs in the
ABS, the TCS will also be inoperative.
Note
To ensure that the TCS works properly, all four wheels must be fitted with
identical tyres. The difference in size of the wheels may lead to an unde-
sired reduction in engine power. Also see ⇒  page 247.Brakes
General notes
New brake pads
New brake pads do not provide optimal performance during the first 200
km; first they must be “run in”. However, the reduced braking capacity may
be compensated by pressing on the brake pedal a little harder. Avoid over-
loading the brakes during run-in.
Wear
The rate of wear on the brake pads depends a great deal on how you drive
and the conditions in which the vehicle is operated. Negative factors are, for
instance, city traffic, frequent short trips or hard driving with abrupt starts
and stops.
Wet roads or road salt
In certain conditions, such as in heavy rain, or after washing the vehicle or
driving through water, the full braking effect can be delayed by moisture (or
in winter by ice) on the discs and brake pads. In this case the brakes should
be dried by pressing the brake pedal several times.
When the speed is over 80 km/h and the windscreen wipers are on, the
brake system moves the pads towards the brake discs for a few seconds.
This occurs - without the driver knowing - at regular intervals and allows a
faster response from the brakes when driving on wet roads.
The effectiveness of the brakes can also be temporarily reduced if the vehi-
cle is driven for some distance without using the brakes when there is a lot
of salt on the road in winter. In this case, the layer of salt on the brake discs
and pads has to wear off before braking.
Corrosion
There may be a tendency for corrosion to form on the discs and dirt to build
up on the brake pads if the vehicle is used infrequently or the brakes are
not used very often. 
