180segments combined with a discontinuous beep indicate the presence of an
obstacle. As the vehicle gets closer to the obstacle, the colour of the segment
changes to red and the acoustic signal beeps continuously. When the penul-
timate segment is displayed, this means that the vehicle has reached the
collision zone. Stop moving immediately! ⇒.
WARNING
•The parking aid is not a replacement for driver awareness. The driver is
personally responsible for safe parking and other manoeuvres.•The sensors have blind spots in which obstacles are not registered.
Always look out for small children and animals because the system will not
always detect them. Always pay attention when reversing to avoid acci-
dents.•Always keep a close eye on the area around the vehicle and make full
use of the rear view mirrors.Caution
Please note that low obstacles detected by the system may no longer be
registered by the sensors as the vehicle moves closer, so the system will not
give any further warning. Certain kinds of obstacles (such as wire fences,
chains, thin painted posts or trailer draw bars, etc) may not always be
detected by the system, so take care not to damage the vehicle in such cases.
Note
•Please refer to the notes on towing ⇒ page 180.•There is a slight delay in the picture display.
To w i n g b r a c k e tIn towing mode, the rear parking aid sensors are not enabled when you select
reverse gear or press the switch
. This function may not be guaranteed on
towing brackets that are not factory fitted. This results in the following restric-
tions:
SEAT Parking System*
No warning is given.
SEAT Parking System Plus*
There is no rear distance warning. The system will still give a warning when
obstacles are detected while driving forward. The optical display changes to
towing mode.
Fault messagesIf you hear a long beep for a few seconds and the LED on the switch
* starts
flashing when you switch on the parking aid, a system fault has occurred.
Please refer the problem to an Authorised SEAT dealer or specialised work-
shop.
Note
If the fault is not corrected before you switch off the ignition, it will only be
indicated by the flashing LED on the switch
 the next time you switch on
the parking aid.

Cruise control*Description
The cruise control system is able to maintain the set speed in
the range of 30 km/h to 180 km/h.Once the speed setting has been saved, you may take your foot off the accel-
erator.
WARNING
It could be dangerous to use the cruise control system if it is not possible
to drive at constant speed.•Do not use the cruise control system when driving in dense traffic, on
roads with lots of bends or on roads with poor conditions (with ice, slippery
surfaces, loose grit or gravel), as this could cause an accident.•Always switch the cruise control system off after using it in order to
avoid an involuntary use.•It is dangerous to use a set speed which is too high for the current road,
traffic or weather conditions. Risk of accident.Note
The cruise control cannot maintain a constant speed when descending down-
hill. The vehicle will accelerate due to its own weight. Use the foot brake to
slow the vehicle.

When you increase speed with the accelerator and then release the pedal, the
system will automatically restore the set speed. This will not be the case,
however, if the vehicle speed is more than 10 km/h higher than the stored
speed for longer than 5 minutes. The speed will have to be stored again.
Cruise control is switched off if you reduce speed by depressing the brake
pedal. You can reactivate the control by pressing once on the upper part of the
rocker switch
RES/+ ⇒ page 182, fig. 133 .
WARNING
It is dangerous to use a set speed which is too high for the current road,
traffic or weather conditions. Risk of accident.Switching off the system temporarily*The cruise control system will be switched off in the following situations:•if the brake pedal is depressed,
•if the clutch pedal is depressed,•if the vehicle is accelerated to over 180 km/h,•when the lever is moved to the position “CANCEL” without reaching
the “OFF” position. Once the “CANCEL” operation is completed, the lever is
released and returns to its initial position.

Technical Specifications
Practical TipsIntelligent technologyBrakesBrake servoThe brake servo increases the pressure you apply to the brake pedal. It works
only when the engine is running .
If the brake servo is not functioning due to a malfunction, or if the vehicle has
to be towed, you will have to press the brake pedal considerably harder to
make up for the lack of servo assistance.
WARNING
The braking distance can also be affected by external factors.•Never let the vehicle coast with the engine switched off. Failure to do so
could result in an accident. The braking distance is increased considerably
when the brake servo is not active.•If the brake servo is not working, for example when the vehicle is being
towed, you will have to press the brake pedal considerably harder than
normal.
Hydraulic Brake Assist (HBA)*
The Hydraulic Brake Assist function (HBA) is only included in
vehicles with ESP.In an emergency, most drivers brake in time, but not with maximum force.
This results in unnecessarily long braking distances.
This is when the brake assist system comes into action. When pressing the
brake pedal rapidly, the assistant interprets it as an emergency. It then very
quickly builds up the full brake pressure so that the ABS can be activated
more quickly and efficiently, thus reducing the braking distance.
Do not reduce the pressure on the brake pedal. The brake assist system
switches off automatically as soon as you release the brake.
Emergency braking warning
If the vehicle is braked suddenly and continuously at a speed of more than 80
km/h, the brake light flashes several times per second to warn vehicles
driving behind. If you continue braking, the hazard warning lights will come
on automatically when the vehicle comes to a standstill. They switch off auto-
matically when the vehicle starts to move again.
WARNING
•The risk of accident is higher if you drive too fast, if you do not keep
your distance to the vehicle in front, and when the road surface is slippery
or wet. The increased accident risk cannot be reduced by the brake assist
system.

Intelligent technology
188Electronic Stability Programme (ESP)*
ESP reduces the danger of skidding by braking the wheels individually.
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 tends to oversteer, the system will act on the front
wheel on the outside of the turn.
Steering manoeuvre recommendations
This is a complementary safety function included in the ESP This function aids
the driver to better stabilize the vehicle in a critical situation. For example, in
case of sudden braking surface with varied adherence, the vehicle will tend
to destabilise its trajectory to the right or to the left. In this case the ESP
recognizes the situation and helps the driver with a counter steering
manoeuvre from the power steering.
This function simply provides the driver with a recommended manoeuvre in
critical situations.
The vehicle does not steer itself with this function, the driver has full control
of the vehicle at all times.
WARNING
•It must be remembered that ESP cannot defy the laws of physics. This
should be kept in mind, particularly on slippery and wet roads and when
towing a trailer.•Always adapt your driving style to suit the condition of the roads and
the traffic situation. Do not let the extra safety afforded by ESP tempt you
into taking any risks when driving, as this can cause accidents.
Caution
•In order to ensure that ESP functions correctly, all four wheels must be
fitted with the same tyres. Any differences in the rolling radius of the tyres can
cause the system to reduce engine power when this is not desired.•Modifications to the vehicle (e.g. to the engine, the brake system, running
gear or any components affecting the wheels and tyres) could affect the effi-
ciency of the ABS, EDL, ESP and TCS.Anti-lock brake system (ABS)The anti-lock brake system prevents the wheels locking during braking
⇒ page 186.Electronic differential lock (EDL)*
The electronic differential lock helps prevent the loss of trac-
tion caused if one of the driven wheels starts spinning.EDL helps the vehicle to start moving, accelerate and climb a gradient in slip-
pery conditions where this may otherwise be difficult or even impossible.
The system will control the revolutions of the drive wheels using the ABS
sensors (in case of an EDL fault the warning lamp for ABS lights up)
⇒ page 84.
At speeds of up to approximately 80 km/h, it is able to balance out differ-
ences in the speed of the driven wheels of approximately 100 rpm caused by
a slippery road surface on one side of the vehicle. It does this by braking the
wheel which has lost traction and distributing more driving force to the other
driven wheel via the differential.

194change down into a lower gear or range (depending on the type of trans-
mission). This makes use of engine braking and relieves the brakes.•Never let the brakes “drag” by applying light pressure. Continuous
braking will cause the brakes to overheat and the braking distance will
increase. Apply and then release the brakes alternately.•Never let the vehicle run with the engine switched off. The braking
distance is increased considerably when the brake servo is not active.•If the brake fluid loses its viscosity and is subjected to heavy use,
vapour bubbles can form in the brake system. This reduces the efficiency of
the brakes.•Non-standard or damaged front spoilers could restrict the airflow to the
brakes and cause them to overheat. Before purchasing accessories please
observe the relevant instructions ⇒page 212, “Technical modifications”.•If a brake circuit fails, the braking distance will be increased consider-
ably. Contact a specialised workshop immediately and avoid unnecessary
journeys.
Exhaust gas purification systemCatalytic converter*To maintain the useful life of the catalytic converter
– Use only unleaded petrol with petrol engines, as lead damages the catalytic converter.
– Do not let the fuel get too low in the tank. – For engine oil changes, do not replenish with too much engine oil
⇒page 226, “Topping up engine oil E”.
– Never tow the vehicle to start it, use jump leads if necessary ⇒page 267.
If you notice misfiring, uneven running or loss of power when the vehicle is
moving, reduce speed immediately and have the vehicle inspected at the
nearest specialised workshop. In general, the exhaust gas warning lamp will
light up when any of the described symptoms occur ⇒page 77. If this
happens, unburnt fuel can enter the exhaust system and escape into the envi-
ronment. The catalytic converter can also be damaged by overheating.
WARNING
The catalytic converter reaches very high temperatures! There is a risk of
fire.•Never park where the catalytic converter could come into contact with
dry grass or flammable materials under the vehicle.•Do not apply additional underseal or anti-corrosion coatings to the
exhaust pipes, catalytic converter or the heat shields on the exhaust
system. These materials could catch fire when the vehicle is being driven.Caution
Never run the fuel tank completely dry because the irregularity of the fuel
supply may cause ignition problems. This allows unburnt fuel to enter the
exhaust system, which could cause overheating and damage the catalytic
converter.
For the sake of the environment
Even when the emission control system is working perfectly, there may be a
smell of sulphur from the exhaust gas under some conditions. This depends

solved by changing to another brand of fuel.
Diesel engine particulate filter*
The diesel engine particulate filter eliminates soot produced
by burning diesel.Your vehicle is fitted with a DPF (Diesel particulate filter) if the vehicle data
sticker (back cover of the “Maintenance Programme”) lists the PR code 7GG
or 7MG
⇒fig. 136.
The diesel engine particulate filter eliminates most of the soot from the
exhaust gas system. Under normal driving conditions, the filter cleans itself.
If the driving conditions do not allow the filter to clean itself (for example,
multiple short trips) the filter will be obstructed by dust and pollen and the
indicator
 for the diesel engine particulate filter indicator will light up. This
does not represent a fault, it is a warning that indicates that the filter has not been able to regenerate automatically and that you must carry out a cleaning
cycle, as indicated in
⇒page 84.

there is a risk of fire.Caution
•Your vehicle is not designed to use biodiesel fuel. Never, under any
circumstances refuel with biodiesel. The use of biodiesel fuel could damage
the engine and the fuel system. The addition of biodiesel to diesel by the
diesel producer in accordance with standard EN 590 is authorised and will
not cause damage to the engine or the fuel system.•Using diesel fuel with a high sulphur content may significantly reduce the
working life of the diesel particulate filter. Your Authorised Service Centre will
be able to tell you which countries have diesel with a high sulphur content.Economical and environmentally friendly
