Starting
The engine is started when the key is in this position. Electrical components
with a high power consumption are switched off temporarily.
Every time the vehicle is started again, the ignition key must be turned to
position . The
repetitive start prevention lock of the ignition prevents
possible damage to the starter motor if the engine is already running.
WARNING
•The ignition key must NOT be removed from the lock until the vehicle
comes to a standstill. Otherwise, the steering could be immediately
blocked- Risk of accident!•Always remove the key from the ignition when leaving the vehicle, even
for a short period. This is especially important if children or disabled
people are left alone in the vehicle. They could accidentally start the
engine or work electrical equipment such as the electric windows, conse-
quently resulting in an accident.•Unsupervised use of the keys could start the engine or any electrical
system, such as the electric window. This could 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 its correct code.
Note
A perfect operation of the vehicle is ensured if genuine SEAT keys are used.Starting and stopping the engineStarting petrol engines
The engine can only be started using a genuine SEAT key with
its correct code.– Move the gear lever to the neutral position and depress the
clutch pedal thoroughly and hold it in this position for the starter
to turn the engine on.
– Turn the ignition key to the starting position ⇒page 162.
– Le t go o f the ig nit io n key as so on as the e ngin e star t s; t he sta r ter motor must not run on with the engine.After starting a very hot engine, you may need to slightly press down the
accelerator.
When starting a very cold engine, it may be a little noisy for the first few
seconds until oil pressure has built up in the hydraulic valve compensators.
This is quite normal, and no cause for concern.

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 avoid high engine speeds, driving at
full throttle and over-loading the engine. Risk of engine damage.•The vehicle should not be pushed or towed more than 50 metres to start
the engine. Unburnt fuel could enter the catalytic converter and damage it.•Before attempting to push-start or tow a vehicle in order to start it, you
should first try to start it using the battery of another vehicle. Note and follow
the instructions in ⇒page 267, “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–Stop the vehicle.
– Turn the ignition key to position ⇒page 162, fig. 117 .
After switching the engine off, the radiator fan may run on for up to 10

temperature increases due to the heat accumulated in the engine compart-
ment or due to its prolonged exposure to solar radiation.
WARNING
•Never switch the engine off until the vehicle is completely stationary.•The brake servo works only when the engine is running. With the
engine switched off, more strength is needed to brake. As normal brake
operation cannot be performed, risk of accidents and serious injury may
exist.•The steering lock can be immediately blocked once the key is removed
from the ignition. The steering wheel cannot be turned. Risk of accident.Caution
When the engine has been running under a heavy load for a long period, heat
can accumulate in the engine compartment and cause engine damage. For
this reason, you should idle the engine for approx. 2 minutes before you
switch it off.

burns and other injury.•Due care must be taken to avoid any risk of fire or explosion.•When parking the vehicle in a closed area (for example in a garage),
make sure that there is adequate ventilation, either natural or mechanical,
to neutralise the LPG in the event of a leak.Note
•If frequent short journeys are made, especially when the outside temper-
ature is low, the vehicle will tend to run on petrol more often than on LPG.
Therefore, the petrol tank may empty before the LPG tank.•The notification LPG mode not possible may be displayed.Start-Stop function*Description and operationThe Start-Stop function stops the engine when the vehicle is
stopped and starts it automatically when required. – When the vehicle is stopped, put it in neutral and release the

the motorway or in the city.
Selecting the manual programme (tiptronic)
This programme allows driving similar to a manual gearbox.
This programme may be accessed using the selector lever or from the
steering wheel controls when this option is fitted ⇒page 174.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. – Press and release the brake pedal, at the same time press the
button on the selector lever.
The lock is only activated when the vehicle is stopped or at a speed of less
than 5 km/h. At higher speeds, the lock is automatically released in position
N.
For rapid changes of position (e.g. from R to D) the lever will not lock. If the
lever remains in the position N more than one second then it is locked. With
the automatic lock, the lever is prevented passing from P and N to any other
gear without first pressing the brake pedal.
The selector lever must be put in the position P in order to remove the key.Driving with an automatic gearbox* / DSG automatic gearbox*

174•If you must stop on a hill, always hold the vehicle using the footbrake
to avoid rolling back.•The footbrake must not be held for a long period of time, not even
lightly; continuous braking will cause overheating of the brakes and a
reduction or even a loss of braking power and a significant increase in
braking distances.•Never allow the vehicle to coast down a gradient with the selector lever
in positions N or D, even when the engine is not running. For descents, the
use of the tiptronic programme is recommended to keep the speed
reduced.Caution
•Never use the automatic gearbox to hold the vehicle stationary on a hill,
even for short periods, as this may overheat the gearbox and cause damage.
Apply the handbrake or depress the foot brake to hold the vehicle in position.•If the vehicle is allowed to roll with the engine stopped but the selector in
position N then the gearbox may be damaged because it will not be
lubricated.

Changing gear with the steering wheel levers
– Press the right paddle lever ( +OFF) towards the steering
wheel to change up ⇒ page 174, fig. 128.
– Press the left paddle towards the steering wheel to change
down ⇒page 174, fig. 128 .Using the paddle levers on the steering wheel, you can access manual driving
mode regardless of the pre-selected driving mode.
General information about driving in tiptronic mode
When accelerating, the automatic gearbox / DSG automatic gearbox goes
into a higher gear a little before the engine reaches its maximum permitted
revolutions.
If a lower gear is selected, the automatic gearbox / DSG automatic gearbox
will only change down when the engine cannot go over its maximum
permitted revolutions.
If tiptronic is selected whilst the vehicle is in motion and the automatic
gearbox / DSG automatic gearbox is in third gear and selector lever position
D, tiptronic mode will then also be in third gear. Changing gears in the normal or sport programme using the steering wheel
paddle levers
If the paddle levers ⇒
page 174, fig. 128 are used in the normal or sport
programme, the system switches temporarily to tiptronic mode. To exit
tiptronic mode again, press the right paddle lever towards the steering
wheel for approximately one second. You will also leave tiptronic mode if the
paddle levers are not moved for a certain time.
Note
•The gearbox controls on the steering wheel can operate with the selector
lever in any position and with the vehicle in motion.Kickdown feature
This feature allows maximum acceleration.If you press the accelerator down thoroughly, the gearbox automatically
changes down, depending on speed and e ngine speed, into a lower gear to
take full advantage of give the vehicle maximum acceleration.
The gearbox does not change gear until the engine reaches the maximum
determined engine speed for the gear.
WARNING
You could lose control of the vehicle if you accelerate on slippery road
surfaces. Risk of serious injury.•Be particularly careful when using the kickdown features on slippery
road surfaces. With a fast acceleration, the vehicle could lose traction and
skid.•You should use the kickdown feature only when traffic and weather
conditions allow it to be used safely.

– Switch the engine off and remove the key from the ignition. 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 rolls against the kerb if it started
to roll.•If the vehicle is parked facing downhill, turn the front wheels so that they
point towards the kerb .•If the vehicle is parked 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
engaging 1st 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 alone in the vehicle. They could set the vehicle in
motion, for example, by releasing the handbrake or the gear lever.
•Depending on weather conditions, it may become extremely hot or cold
inside the vehicle. This can be fatal.
Hill-start aid*
This function is only included in vehicles with ESP.This device helps when starting uphill.
These are the basic operation conditions: doors closed, brake pedal pressed
down and vehicle in neutral. The system gets activated on engaging gear.
This system also works when reversing uphill.
After removing your foot from the brake pedal, the braking force is maintained
for a few seconds to prevent the vehicle from moving backward when putting
into gear. This short space of time is enough to start the vehicle with ease.
This system also works when reversing uphill.
WARNING
•If you do not start the vehicle immediately after taking your foot off the
brake pedal, the vehicle may start to roll back under certain conditions.
Depress the brake pedal or use the hand brake immediately.•If the engine stalls, depress the brake pedal or use the hand brake
immediately.•When following a line of traffic uphill, if you want to prevent the vehicle
from rolling back accidentally when starting off, hold the brake pedal down
for a few seconds before starting off.WARNING (continued)

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.
