WARNING
•An improper use of the key can cause serious injuries.•Never leave children or disabled persons in the vehicle. In case of emer-
gency, they may not be able to leave the vehicle and not manage on their
own.•Never forget the keys inside the vehicle. Otherwise, this could result in
serious injuries, accidents or even the theft of your vehicle. Always take the
key with you when you leave the vehicle.•An uncontrolled use of the key could start the engine or activate any
electric equipment (e.g. electric windows), causing risk of accident. The
vehicle can be locked when using the remote control key. This could
complicate the aid in case of emergency.Note
•The remote control can be programmed by means of pressing the
unlocking button once; as a result, only the driver door will unlock. When the
button is pressed once more, all doors and the tailgate will be unlocked.•The remote control functions only when you are in range ⇒page 106,
fig. 63 (red area).•If the vehicle is unlocked using the button, it will lock again auto-
matically if any of the doors or the tailgate are not opened within 30 seconds
after unlocking it. This function prevents the vehicle from remaining unlocked
if the unlock button is pressed by mistake.•If the vehicle cannot be opened and closed using the remote control, the
remote control key will have to be re-synchronised ⇒page 107.
Changing the batteryIf the battery indicator does not flash when the buttons are pushed, the
battery must be replaced.
Caution
The use of inappropriate batteries may damage the radio frequency remote
control. For this reason, always replace the dead battery with another of the
same size and power.
For the sake of the environment
Used batteries must be disposed of at an appropriate waste facility or
through an authorised service, given that their components can affect the
environment.Synchronising the remote control key
If it is not possible to unlock or lock the door with the remote
control, it should be re-synchronised.–Press the ⇒page 106, fig. 62 button on the remote control.
– Then close the vehicle using the key bit within one minute.It is possible that the vehicle could no longer be opened and closed with the
remote control if the button is repeatedly pressed outside of the effective
range of the radio frequency remote control. The remote control key will have
to be resynchronised.
Spare remote control keys are available in your Authorised Service Centres,
where they must be matched to the locking system.

•The windscreen will be wiped again after approximately five seconds once
the “automatic wipe/wash system” has been operated, provided the vehicle
is in transit (drip function). If you activate the wipers less than three seconds
after the drip function, a new wash sequence will begin without the last wipe.
For the “drip” function to work again, you have to turn the ignition off and
then on again.•When the “interval wipe function” is on, the intervals are directly propor-
tional to the speed. This way, the higher the vehicle speed the shorter the
intervals.•The wiper will try to wipe away any obstacles that are on the windscreen.
The wiper will stop moving if the obstacle blocks its path. Remove the
obstacle and switch the wiper back on again.•Before removing any objects that may be trapped in the side areas of the
windscreen, always move the wiper arms to the service position (horizontal).•The heat output of the heated jets is controlled automatically when the
ignition is switched on, depending upon the outside temperature.
Rain sensor*
The rain sensor controls the frequency of the windscreen
wiper intervals, depending on the amount of rain.

fuel. The temperature continues to self-regulate. The set temperature can
then only be reached if it is higher than the outside temperature.
Driver and passenger temperature control
The button controls the synchronisation of the 2 Climatronic climate
zones.
When the button is on (LED lit), the climate zone of the Climatronic is
personalised, for example: Driver side temperature 22 °C and passenger side
temperature 23 °C.
When the button is off (LED off), the climate zone of the Climatronic is
synchronised, for example: Driver side temperature 22 °C and passenger side
temperature 22 °C.
If the button is off and the passenger side temperature is changed, the
function is automatically activated.Air recirculation mode
Air recirculation mode prevents fumes or unpleasant smells
from coming from the outside.–Press the button ⇒page 157, fig. 113 to switch air recir-
culation mode on or off. It is switched on if the following symbol
appears in the display
.
Air recirculation mode prevents strong odours in the ambient air from
entering the vehicle interior, for example when passing through a tunnel or in
a traffic jam.
With low outside temperatures, the air recirculation increases the effective-
ness of the heating system by heating the air inside the vehicle rather than
the air from outside. With high outside temperatures, the air recirculation increases the effective-
ness of the air conditioning system by cooling the air inside the vehicle rather
than the ambient air.
If the windscreen air output is on and the air recirculation mode is pressed,
this remains active. When the recirculation mode is on, if the air distribution
towards the windscreen mode is selected, the recirculation mode is deacti-
vated. For safety reasons, the air recirculation mode should not be
connected.
WARNING
In air recirculation mode, no cold air from the outside enters the vehicle
interior. If the air conditioning system is switched off, the windows can
quickly mist over. Therefore, never leave the air recirculation mode
switched on for a long time (risk of accident).General notesPollution filter
The pollution filter (a combined particulate filter and active carbon filter)
serves as a barrier against impurities in the outside air, including dust and
pollen.
For the air conditioner to work with maximum efficiency, the pollution filter
must be replaced at the intervals specified in the Service Schedule.
If the filter loses efficiency prematurely due to use in areas reaching very high
pollution levels, the pollen filter must be changed more frequently than
stated in the Service Schedule.
Air conditioner
When the air conditioning system is switched on, not only the temperature,
but also the air humidity in the vehicle interior is reduced. This improves

comfort for the vehicle occupants and prevents misting of the windows when
the ambient air humidity is high.
If the air conditioning system cannot be switched on this may be caused by
the following reasons:
•The engine is not running.•The button is disconnected.•The outside temperature is below +3 °C.•The air conditioning system compressor has been temporarily switched
off because the engine coolant temperature is too high.•The air conditioner fuse is faulty.•Another fault in the vehicle. Have the air conditioner checked by a special-
ised workshop.Caution
•If you suspect that the air conditioner is damaged, switch it off with the button to prevent further damage and have it checked by a specialised
workshop.•Repairs to the air conditioner require specialist knowledge and special
tools. Therefore, we recommend you to take the vehicle to a specialised work-
shop.Note
•If the humidity and temperature outside the vehicle are high, condensa-
tion can drip off the evaporator in the cooling system and so forming a puddle
underneath the vehicle. This is completely normal and there is no need to
suspect a leak.•Keep the air intake slots in front of the windscreen free of snow, ice and
leaves to ensure heating and cooling are not impaired, and to prevent the
windows from misting over.
•The air from the vents flows through th e vehicle interior and is extracted
by slots designed for this purpose. Therefore, do not cover these slots with
items of clothing or other objects.•The air conditioner operates most effectively with the windows and the
sliding/tilting sunroof* closed. However, if the temperature inside the vehicle
is excessive because of the sun, the air inside can be cooled faster by opening
the windows for a short time.•Do not smoke while air recirculation mode is on, as smoke drawn into the
air conditioning system leaves a residue on the evaporator, producing a
permanent unpleasant odour.•It is advisable to connect the air conditioning at least once a month, to
lubricate the system gaskets and prevent leaks. If a decrease in the cooling
capacity is detected, an Authorised Service Centre should be consulted to
check the system.

•Adjust the driver seat or steering wheel so that there is a distance of at
least 25 cm between the steering wheel and your chest ⇒page 160,
fig. 115 . If you fail to observe the minimum distance, the airbag will not
protect you. Risk of fatal injury.•If your physical constitution does not allow you to maintain the
minimum distance of 25 cm, contact an Authorised Service Centre. The
Authorised Service Centre will help you to decide if special specific modifi-
cations are necessary.•If you adjust the steering wheel so that it points towards your face, the
driver airbag will not protect you properly in the event of an accident. Make
sure that the steering wheel points towards your chest.•When driving, always hold the steering wheel with both hands on the
outside of the ring at the 9 o’clock and 3 o’clock positions. Never hold the
steering wheel at the 12 o’clock position, or in any other manner (e.g. in
the centre of the steering wheel, or on the inside of the rim). In such cases,
if the airbag is triggered, you may sustain injuries to the arms, hands and
head.
SafetyElectronic Stabilit y Programme (ESP)*
ESP helps make driving safer in certain situations.The Electronic Stability Programme (ESP) contains the electronic differential
lock (EDL) and the traction control system (TCS). The ESP function works
together with the ABS. Both warning lamps will light up if the ESP or ABS
systems are faulty.
The ESP is started automatically when the engine is started.
The ESP is always active, and cannot be switched off. With the ESP switch it is
only possible to switch TCS off.
The TCS can be deactivated when in cases where wheel sliding is desirable.

NoteYour Authorised Service or a specialised workshop can tell you if your vehicle
is equipped with this system.Acoustic parking aid system*General notesVarious 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.
When you are parking, the SEAT Parking System Plus* warns you acoustically
and optically
23) about obstacles “in front of” and “behind” the vehicle.
Note
To ensure the acoustic parking aid works properly, the sensors must be kept
clean and free of snow and ice.
SEAT Parking System: Description
The Parking System is an acoustic parking aid.Sensors are located in the rear bumper. When the sensors detect an obstacle,
you are alerted by acoustic 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. Do not drive on!
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).
The parking aid is switched on automatically when reverse gear is engaged.
You will hear a brief confirmation tone.
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.

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.

Intelligent technology
192•The power steering system requires a special hydraulic fluid. The
container is located in the engine compartment (front left). The correct fluid
level in the reservoir is important for the power steering to function properly.
The hydraulic fluid level is checked at the Inspection Service.
