Starting
The engine is started when the key is in
this position. Electrical components
with a high power consumption are switched off temporarily.
Each time that the vehicle must be started, the ignition key must be turned to
the position . The repetitive start prevention lock of the ignition prevents
possible damage to the starter motor if the engine is already running.
WARNING
•
Wait for the vehicle to come to a standstill before removing the ignition
key from the lock. The steering lock could be activated immediately - Risk
of accident!
•
Always remove the key from the ignit ion lock when leaving the vehicle,
even if you only intend to be gone for a short period. This is especially
important if you must leave children or disabled people in the vehicle.
•
They could accidentally start the engine or work electrical equipment
such as the windows possibly resulting in an accident.
•
Unsupervised use of the keys could result in the engine being started
or electrical systems, such as the electric windows, being used. This can
result in serious injury.Caution
The starter motor will only work when the engine is stopped (ignition key
position ).
Electronic immobiliser
The immobiliser prevents unauthorised persons from driving
the vehicle.Inside the key there is a chip that deactivates the electronic immobiliser auto-
matically when the key is inserted into the ignition.
The 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 genuine SEAT key with the correct
code.
Note
The vehicle cannot be operated properly if you do not have a genuine SEAT
key.Starting and stopping the engineStarting petrol engines
The engine can only be started using a genuine SEAT key with
the correct code.– Move the gear lever to the neutral position and depress the clutch pedal fully and hold it in this position, the starter will then
only have to turn the engine.
– Turn the ignition key to the starting position ⇒page 152.

Glow plug system for the diesel engine
To avoid unnecessary load on the battery, do not use any other major elec-
trical equipment while the
glow plugs are pre-heating.
Start the engine as soon as the glow plug warning lamp ⇒page 81 goes out.
Starting the engine after the fuel tank has been completely run dry
If the fuel tank has been completely ru n dry, it may take longer than normal
(up to one minute) to start the engine af ter refuelling with diesel fuel. This is
because the system must eliminate air first.
WARNING
•
Never start or run the engine in unventilated or closed rooms. The
exhaust fumes contain carbon monoxide, an odourless and colourless
poisonous gas. Risk of fatal accidents. Carbon monoxide can cause loss of
consciousness. It can also cause 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 avo id high engine speeds, driving at
full throttle and over-loading th e engine. Risk of engine damage.
•
The vehicle should not be pushed or towed for more than approximately
50 metres to start the engine. Fuel could enter the catalytic converter and
damage it.
•
Before attempting to push-start or tow a vehicle to start it, you should first
try to start it using the battery of another vehicle. Note and follow the instruc-
tions ⇒ page 248, “Jump-starting”.
For the sake of the environment
Do not warm up the engine by running the engine with the vehicle stationary.
You should drive off as soon as you start the engine. This helps the engine
reach operating temperature faster and reduces emissions.Switching off the engine– Stopping the engine.
– Turn the ignition key to position ⇒page 152, fig. 115 .After the engine is switched off the radiator fan may run on for up to 10
minutes, even if the ignition is switched of f. It is also possible that it will turn
itself on once more if the temperature of the coolant increases due to the
elimination of built-up heat in the engine compartment or if this is heated due
to prolonged exposure to the heat of the sun.
WARNING
•
Never switch off the engine until the vehicle is stationary.
•
The brake servo works only when the engine is running. You will need
more strength to brake the vehicle when the engine is switched off. As you
cannot brake in the normal manner, there is a greater risk of accidents and
serious injury.
•
The steering lock can engage immediately when the key is removed
from the ignition lock. The vehicle cannot be steered. Risk of accident.

158Driving programmes
The automatic gearbox / direct shift gearbox (DSG) has three
programmes.Selecting the economic programme
– This programme selects a higher gear earlier rather than remain
in a lower gear.
– Put the selector lever into position D to drive forwards
– Put the selector lever into position R to reverse. This position is
shared by all programmes for reversing.
Selecting the sport programme
– Move the lever to position S.If you select the sport programme, S, the programme is designed for a sports
mode, that is, a programme which changes up at higher engine speeds to use the full power of the engine. This pr
ogramme is not recommended for use on
the motorway or in the city.
Selecting manual programme (tiptronic)
This programme allows the vehicle to be driven as if with a manual gearbox.
This programme may be accessed using the selector lever or from the
steering wheel controls when t his option it is fitted ⇒page 161.
Selector lever locking
The selector lever lock prevents gears from being engaged
inadvertently, which would cause the vehicle to move.Releasing the selector lever lock
–Start the vehicle.

Using the Tiptronic gear system
The Tiptronic system allows th e driver to manually select
gears
General points about the Tiptronic gear system
Changing gear with the selector lever
– Put the lever in the position D and press towards the right to
enter the Tiptronic gate ⇒fig. 122.
– Press the gear lever forwards (+) to select a higher gear.
– Press the gear lever back (-) to select a lower gear.
Changing gear using the steering wheel levers
– Press the right lever (+) towards the steering wheel to change up ⇒fig. 123.
– Press the left lever (-) towards the steering wheel to change down ⇒fig. 123.The manual programme can be selected with the levers on the steering wheel
irrespective of the driving mode which has been preselected.
General points about the Tiptronic gear system
When accelerating, the automatic/DSG gearbox automatically shifts up to the
next gear shortly before the maximu m permitted engine speed is reached.
If a lower gear is selected, the automatic gearbox / direct shift gearbox does
not change down until the point is re ached where the engine could no longer
overrev.
If the “tiptronic” is selected whilst the vehicle is in motion and the automatic
gearbox / direct shift gearbox is in the 3rd gear in selector lever position D,
the “tiptronic” will then also be in the 3rd gear.

Note•
The steering wheel controls may be us ed in all selector lever positions
while driving.
HandbrakeUsing the handbrake
The handbrake should be applied firmly to prevent the
vehicle from accidentally rolling away.Always apply the handbrake when you leave your vehicle and when
you park. Applying the handbrake
– Pull the handbrake lever up firmly ⇒
fig. 124.
Releasing the handbrake
– Pull the lever up slightly and press the locking knob in the direc- tion of the arrow ⇒fig. 124 and guide the handbrake lever down
fully ⇒ .
Always apply the handbrake firmly; this prevents you driving with the hand-
brake applied ⇒.
The handbrake warning lamp
 lights up when the handbrake is applied
and the ignition switched on. The warning lamp goes out when the hand-
brake is released.
If you drive faster than 6 km/h with the handbrake on, the following
message* will appear in the instrument display: HANDBRAKE ON. Also, an
audible warning is given.
WARNING
•
Never use the handbrake to slow down the vehicle when it is in motion.
The braking distance is considerably longer, as braking is only applied to
the rear wheels. Risk of accident!
•
If it is only partially released this will cause overheating of the rear
brakes, which can impair the function of the brake system and could lead
to an accident. This also causes premature wear on the rear brake
pads/linings.Caution
Always apply the handbrake before you leave the vehicle. The first gear
should also be selected.

Parking
The handbrake should always be firmly applied when the
vehicle is parked.Always note the following points when parking the vehicle:
– Use the foot brake to stop the vehicle.
–Apply the handbrake.
– The first gear should also be selected.
– Switch off the engine and remove the key from the ignition lock.
Turn the steering wheel slightly to engage the steering lock.
– Always take you car keys with you when you leave the vehicle ⇒ .Additional notes on parking the vehicle on gradients:
Turn the steering wheel so that the vehicle would roll against the kerb if it did
start to roll.•
If the vehicle is facing downhill, turn the front wheels so that they point
towards the kerb.
•
If the vehicle is facing uphill , turn the front wheels so that they point away
from the kerb .
•
Secure the vehicle as normal by applying the handbrake firmly and
selecting first gear.
WARNING
•
Take measures to reduce the risk of injury when you leave your vehicle
unattended.
•
Never park where the hot exhaust system could ignite inflammable
materials, such as dry grass, low bushes, spilt fuel etc.
•
Never allow vehicle occupants to remain in the vehicle when it is
locked. They would be unable to open the vehicle from the inside, and
could become trapped in the vehicle in an emergency. In the event of an
emergency, locked doors will delay assistance to occupants.
•
Never leave children unsupervised in the vehicle. They could set the
vehicle in motion, for example, by releasing the handbrake or the gear
lever / selector lever.
•
Depending on weather conditions, it may become extremely hot or cold
inside the vehicle. This can be fatal.
Acoustic parking aid system*Rear parking aid
The parking aid system will use an acoustic signal to warn of
the approach of any object towards the rear of the vehicle.Description
The acoustic parking aid system will measure the distance between the rear
of the vehicle and any possible obstacle using four ultrasonic sensors located
on the rear bumper. The measuring range of the sensors starts at approxi-
mately and depending on the nature of the obstacle at a distance of:•
side of the rear bumper: 0.8 m
•
centre of the rear bumper: 1.3 mWARNING (continued)

The TCS should be switched on again afterwards as soon as possible.
WARNING
•
It must be remembered that TCS cann
ot defy the laws of physics. This
should be kept in mind, particular ly 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 wh eels and tyres) could affect the effi-
ciency of the ABS and TCS.
Electronic stabilisation program (ESP)*General notes
The electronic stabilisation program increases the vehicle's
stability on the road.The electronic stabilisation program helps to reduce the danger of skidding.
The electronic stabilisation programme (ESP) consists of ABS, EDL and TCS. Electronic Stabilising Program (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 vehi
cle. If the desired course is not being
maintained (for instance, if the car is starting to skid), then the ESP compen-
sates 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.
WARNING
•
It must be remembered that ESP cann ot 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, 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.Note
To disconnect using the ESP button ⇒page 151.

Checking and refilling levels
216Ty re s e r vi ce l i fe
The service life of tyres is dependent on tyre pressure, driving
style and fitting.
Wear indicators
The original tyres on your vehicle have 1.6 mm high “tread wear indicators”
⇒ fig. 151 running across the tread. Depending on the make, there will be six
to eight of them evenly spaced around the tyre. Markings on the tyre sidewall
(for instance the letters “TWI” or other symbols) indicate the positions of the
tread wear indicators. The minimum tread depth required by law is 1.6 mm
(measured in the tread grooves next to the tread wear indicators). Worn tyres
must be replaced. Different figures may apply in export countries ⇒.
Tyre pressure
Incorrect tyre pressure causes premature wear and could cause tyre blow-out.
For this reason, the tyre pressure should be checked at least once per month
⇒ page 215.
Driving style
Fast cornering, heavy acceleration and hard braking all increase tyre wear.
Changing wheels around
If the front tyres are worn considerably more than the rear ones it is advisable
to change them around as shown ⇒fig. 152 . All the tyres will then last for
about the same time.
Wheel balance
The wheels on new vehicles are balanced. However, various factors encoun-
tered in normal driving can cause them to become unbalanced, which results
in steering vibration.
Unbalanced wheels should be rebalanced, as they otherwise cause excessive
wear on steering, suspension and tyres. A wheel must also be rebalanced
when a new tyre is fitted.
Incorrect wheel alignment
Incorrect wheel alignment causes excessive tyre wear, impairing the safety of
the vehicle. If tyres show excessive wear, you should have the wheel align-
ment checked by an Authorised Service Centre.
