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.SEAT Parking System Plus*: Description
The parking system plus is an acoustic and optical parking
aid.Sensors are located in the front and rear bumpers. When the sensors detect
an obstacle, you are alerted by acoustic and optical signals. The measuring
range of the sensors starts at approximately:
The acoustic signals sound with increasing frequency as you approach the
obstacle. When the vehicle is less than 0.30 m away from the obstacle, the
warning tone will sound continuously. Stop moving immediately!
The volume of the warning beeps will be gradually reduced after about four
seconds if the vehicle remains at a constant distance from a detected
obstacle (it does not affect the permanent acoustic signal).

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.
Switching the cruise cont rol system on and offSwitching on the system
–Push the switch ⇒fig. 131 to the left to ON.

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.
To resume the cruise control, release the brake or clutch pedal or reduce the
vehicle speed to less than 180 km/h and press once on the upper part of the
rocker switch RES/+ ⇒ fig. 134 .WARNING

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.

When the TCS is off, the warning lamp is lit. The TCS should normally
be left on. Only in exceptional circumstances, when the slipping of the wheels
is required, should it be disconnected, for example
•With compact temporary spare wheel.•When using the snow chains.•When driving in deep snow or on soft terrain.•When the vehicle is bogged-down, to free it by rocking.
The TCS should be switched on again as soon as possible.WARNING
•It must be remembered that TCS 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 TCS tempt you
into taking any risks when driving, this can cause accidents.Caution
•In order to ensure that TCS function 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 and TCS.
XDS*
Driveshaft differentialWhen taking a bend, the driveshaft differential mechanism allows the outer
wheel to turn at a higher speed than the inner wheel. In this way, the wheel
that is turning faster (outer wheel) receives less drive torque than the inner
wheel. This may mean that in certain situations the torque delivered to the
inner wheel is too high, causing the wheels to spin. On the other hand, the
outer wheel is receiving a lower drive torque than it could transmit. This
causes an overall loss of lateral grip on the front axle, resulting in understeer
or “lengthening” of the trajectory.
By using the ESP sensors and signals, the XDS system is able to detect and
correct this effect.
Through the ESP, the XDS brakes the inner wheel, thereby counteracting the
excess drive torque in this wheel. This means that the driver’s desired trajec-
tory is much more precise,
The XDS system operates in combination with the ESP and is always active,
even when the traction control, TCS, is disconnected.Electronic Stability Programme (ESP)*General notes
The Electronic Stability Programme increases the vehicle’s
stability on the road.The Electronic Stability Programme helps reduce the danger of skidding.
The Electronic Stability Programme (ESP) consists of ABS, EDL, TCS and
Steering manoeuvre recommendations.

To prevent the disc brake of the braking wheel from overheating, the EDL cuts
out automatically if subjected to excessive loads. The vehicle will continue to
function normally without EDL. For this reason, the driver is not informed that
the EDL has been switched off.
The EDL will switch on again automatically when the brake has cooled down.
WARNING
•When accelerating on a slippery surface, for example on ice and snow,
press the accelerator carefully. Despite EDL, the driven wheels may start to
spin. This could impair the vehicle’s stability.•Always adapt your driving style to suit road conditions and the traffic
situation. Do not let the extra safety afforded by EDL tempt you into taking
any risks when driving, this can cause accidents.Caution
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 EDL ⇒page 212.The traction control system (TCS)The traction control system prevents the drive wheels from spinning when the
vehicle is accelerating ⇒page 186.
All-wheel drive*
On all-wheel drive models, the engine power is distributed to
all four wheelsGeneral notes
The all-wheel drive system operates completely automatically. The propul-
sion force is distributed among the four wheels and adapted to the driving
style and the road conditions.
The all-wheel drive is specially designed to complement the superior engine
power. This combination gives the vehicle exceptional handling and perform-
ance capabilities, both on normal roads and in more difficult conditions, such
as snow and ice.
Winter tyres
Thanks to its all-wheel drive, your vehicle will have plenty of traction in winter
conditions, even with the standard tyres. Nevertheless, we still recommend
that winter tyres or all-season tyres should be fitted on all four wheels when
winter road conditions are expected, mainly because this will give a better
braking response.
Snow chains
On roads where snow chains are mandatory, this also applies to cars with all-
wheel drive.
Changing tyres
On vehicles with all-wheel drive, all four tyres must have the same rolling
circumference ⇒page 242.
WARNING
•Even with all-wheel drive, you should always adjust your speed to suit
the 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.

Brake servo
The brake servo increases the pressure you apply to the brake pedal. The
brake servo works only when the engine is running.
WARNING
•When applying the brakes to clean off deposits on the pads and discs,
select a clear, dry road. Be sure not to inconvenience or endanger other
road users. Risk of accident.•Ensure the vehicle does not move while in neutral, when the engine is
stopped. Failure to do so could result in an accident.Caution
•Never let the brakes “drag” by leaving your foot on the pedal when it is
not necessary to brake. This overheats the brakes, resulting in longer stop-
ping distances and greater wear.•Before driving down a long, steep gradient, it is advisable to reduce speed
and change to a lower gear (or move the gear lever to a lower gear position if
your vehicle has automatic transmission). This makes use of engine braking
and prolongs the service life of the brakes. If you still have to use the brakes,
it is better to brake firmly at intervals than to apply the brakes continuously.Note
•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.•If you wish to equip the vehicle with accessories 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.
Power steering (servotronic*)
Power steering makes it easier to turn the steering wheel
when the engine is running.Power steering assists the driver by reducing the force needed to turn the
steering wheel. In cars equipped with servotronic* power steering the degree
of power assistance is regulated electronically according to road speed.
The power steering will keep on working in spite servotronic* device fails. The
degree of power assistance will, however, no longer adapt to different
speeds. If the electronic regulating system is not working properly, this is
most noticeable when turning the steering wheel at low speeds (for instance
when parking), as more effor t will be required than usual. The fault should be
corrected by a specialised workshop as soon as possible.
Power steering does not work if the engine is off. In this case the steering
wheel requires much more force to turn.
If the steering is held at its turning limit when the vehicle is stationary, this
will place an excessive load on the power steering system. Turning the
steering wheel to its limit places a load on the system, which causes noise. It
will also reduce the idling speed of the engine.
Caution
When the engine is running, do not turn the steering wheel to its limit for
more than 15 seconds. Otherwise, there is a risk of damaging the power
steering.
Note
•The steering wheel can be turned even if the power steering fails or the
engine is switched off (for instance when being towed). However, more effort
will be required to turn the steering wheel.•If the system is leaking or malfunctioning, please take the vehicle to a
specialised workshop as soon as possible.

Driving and the environmentRunning-inRunning in a new engine
The engine needs to be run in over the first 1500 km.Up to 1000 kilometres
– Do not drive at speeds of more than 2/3 the maximum speed.
– Do not accelerate hard.
– Avoid high engine revolutions.
– Do not tow a trailer.
From 1000 to 1500 kilometres
– Speeds can be gradually increased to the maximum road speed
or maximum permissible engine speed (rpm).During its first few hours of running, the internal friction in the engine is
greater than later on, when all the moving parts have bedded in.
For the sake of the environment
If the engine is run in gently, its life will be increased and its oil consumption
reduced.
Braking capacity and braking distance
The braking capacity and braking distance are influenced by
driving situations and road conditions.The efficiency of the brakes depends directly on the brake pad wear. The rate
of wear of the brake pads depends to a great extent on the conditions under
which the vehicle is operated and the way the vehicle is driven. If you often
drive in town traffic, drive short distances or have a sporty driving style, we
recommend that you have the thickness of your brake pads checked by an
Authorised Service Centre more frequently than recommended in the Ser vice
Plan.
If you drive with wet brakes, for example, after crossing areas of water, in
heavy rainfall or even after washing the vehicle, the effect of the brakes is
lessened as the brake discs are wet or even frozen (in winter). In this case the
brakes should be dried by pressing the brake pedal several times.
WARNING
Longer braking distances and faults in the brake system increase the risk
of accidents.•New brake pads must be run in and do not have the correct friction
during the first 400 km. However, the reduced braking capacity may be
compensated by pressing on the brake pedal a little harder. This also
applies when the brake pads have to be changed further on.•If brakes are wet or frozen, or if you are driving on roads which have
been salted, braking power may be lower than normal.•On steep slopes, if brakes are excessively used, they will overheat.
Before driving down a long steep slope, it is advisable to reduce speed and
