2 remote control keys
In certain European markets, vehicles with alarm are equipped with 2 re-
mote control keys.
WARNING
● Always take the key with you when leaving the vehicle, even if you
only intend to be gone for a short time. This is particularly important if
there are children in the vehicle, as they might otherwise be able to start
the engine or use power-operated equipment (e.g. the electric windows),
which could cause injuries.
● Wait for the vehicle to come to a standstill before removing the igni-
tion key from the lock! Otherwise, the steering lock could engage sud-
denly, causing an accident.

Indicator light on the remote control key
The condition of the battery in the remote control key is
monitored by the indicator light.
Fig. 68 LED on the re-
mote control key Condition of the key battery
The indicator light
⇒ Fig. 68 (arrow) flashes when one of the buttons is
pressed. If the indicator light does not light up or flash, this means that the
battery is exhausted and must be replaced.
Replacing the batteries ⇒ page 100. 
Replacing the key battery
Fig. 69 Master key:
Opening the cover
We recommend you have the batteries changed in a specialised
workshop. If you decide to change the used battery yourself, follow
the steps below:
– Carefully prise apart the key ⇒ Fig. 69 A
and the cover B us-
ing a coin.
– Remove the cover in the direction of the arrow.
– Remove the used battery from the cover. 

174Driving
Position 1
The ignition key is inserted in this position. To
engage the steering wheel
lock, take out the key and turn the wheel until you hear the pin engage. You
should always engage the steering lock when you leave the vehicle. This
will help to deter thefts ⇒ 
.
Switching on the ignition/pre-heating glow plugs 2
If the key is difficult to turn in the lock, move the steering wheel (to take the
load off the steering lock mechanism) until the key turns freely. In the case
of vehicles with a diesel engine, the key is turned to this position to preheat
the glow plugs.
Starting the engine 3
The engine is started in this position. Electrical components with a high
power consumption are switched off temporarily.
After the engine has started, the ignition key returns to position 2
by itself.
The ignition key has to be turned back to position 1
before re-starting the
engine. The starter inhibitor in the ignition lock prevents the starter motor
from engaging when the engine is running, as this could cause damage.
Switching off the ignition 1
Turn the ignition key to this position.
WARNING
● Never remove the ignition key until the vehicle is stationary! Other-
wise the steering lock could engage suddenly, which could cause an acci-
dent.
● Always take the key with you when leaving the vehicle, even if you
only intend to be gone for a short time. This is particularly important if
there are children in the vehicle, as they might otherwise be able to start
the engine or use power-operated equipment (e.g. the electric windows),
which could cause injuries.
Note
● If the battery has been disconnected and then reconnected, it will be
necessary to leave the key in position 2
for about 5 seconds before start-
ing the engine.
● Vehicles with automatic gearbox: After switching off the ignition, you
can only remove the ignition key if the selector lever is in position “P” (park-
ing lock). The selector lever is locked after the ignition key has been re-
moved. 
Starting and stopping the engine Starting the engine
The engine can only be started with an original SEAT key.

sitions
Vehicles with a petrol engine:
– Use the foot brake. 

176Driving
WARNING
● Never switch the engine off until the vehicle is stationary.
● The brake servo and the power steering system work only when the
engine is running. You need more strength to steer and brake the vehicle
when the engine is switched off. Given that you will be unable to steer
and brake as usual, this could lead to a risk of accidents and injuries.
CAUTION
If the engine has been running under high load for a long time, there is a
risk of heat building up in the engine compartment after the engine has
been switched off; this could cause engine damage. Therefore, you should
let the engine idle for approximately 2 minutes before you switch it off.
Note
After the engine is switched off the radiator fan may run on for up to 10 mi-
nutes, even if the ignition is switched off. It may also start running again af-
ter some time if the coolant temperature rises due to a build-up of heat un-
der the bonnet, or if the engine is already warm and the engine compart-
ment is heated up further by direct sunlight. 
Start-Stop function* Description and operation
The Start-Stop function stops the engine when the vehicle is stop-
ped and starts it automatically when required.
– When the vehicle is stopped, put it in neutral and release the
clutch pedal. The engine will stop. –
When the clutch pedal is pressed, the engine starts again.
– The instrument panel screen displays information about the sta-
tus of the Start-Stop function ⇒ Fig. 148.
Start-Stop function conditions
● The driver seat belt must be buckled.
● The engine hood must be closed.
● The engine must be at operating temperature
● The steering wheel must not be turned more than 270°.
● The vehicle must not be on a steep gradient.
● The vehicle must not be in reverse.
● A trailer must not be connected.
● The temperature of the passenger compartment must be within the con-
venience limits ( ECON
button should not be selected).
● The windscreen de-mist function must be off.
● Otherwise it requires more than 50% of the airflow that the fan can sup-
ply.
● The temperature must not be set to HI or LO.
● The driver door must be closed.
● The diesel particulate filter must not be in regeneration mode, for diesel
engines.
● The battery charge must not be low for the next start.
● The battery temperature must be between –1°C and 60°C.
Start-Stop function interruption
In the following situations, the Start-Stop function will be interrupted and
the engine will automatically start:
● The vehicle starts moving.
● The brake pedal is pressed several times in a row.
● The battery has been discharged excessively. 

177
Driving
● The Start-Stop System is manually deactivated.
● The windscreen de-mist function is turned on.
● The temperature of the passenger compartment exceeds the comfort
limits (button ECON
should not be selected).
● If more than 50% of the airflow that the fan can supply is ordered.
● Temperature setting HI or LO is selected.
● The engine coolant temperature is insufficient.
● The alternator is faulty, for example the V-belt has ruptured.
● If any of the conditions described in the previous section are not fulfil-
led.
WARNING
Never allow the vehicle to move with the engine off for any reason. You
could lose control of your vehicle. This could cause an accident and seri-
ous injury.
● Power steering does not work when the engine is not running. That is
why it is much more difficult to turn the steering wheel.
● Disconnect the Start-Stop system when driving through water (ford-
ing streams, etc.).
Note
● For vehicles with the Start-Stop function and a manual gearbox, when
the engine is started, the clutch must be pressed.
● When the conditions for the Start-Stop function are not fulfilled, the in-
strument panel displays the Start-Stop indicator dimmed.
● If the steering wheel is turned more than 270°, Stop will not function;
however, the angle of steering wheel turn does not affect starting the vehi-
cle. Activating and deactivating the Start-Stop function

Intelligent technology
Faults in the brake system
If the brake pedal travel should ever increase suddenly, this may mean that
one of the two brake circuits has failed. Drive immediately to the nearest
specialised workshop and have the fault repaired. Drive there slowly and re-
member that you will have to apply more pressure on the brake pedal and
allow for longer stopping distances.
Low brake fluid level
Malfunctions can occur in the brake system if the brake fluid level is too
low. The brake fluid level is monitored electronically.
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.
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 en-
gine 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 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. Brake servo
The brake servo assists the driver when braking
The brake servo increases the pressure you apply to the brake pedal. The
brake servo works only when the engine is running.
WARNING
Ensure the vehicle does not move while in neutral, when the engine is
stopped. Failure to do so could result in an accident.
Note
If the brake servo is not working, e.g. because the vehicle has to be towed
or because it is broken, you will have to press the brake pedal considerably
harder to make up for the lack of servo assistance. 
Power steering
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.
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
● If the power steering should fail at any time or the engine is switched off
(for instance when being towed), the vehicle can still be steered. 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.
● The power steering system requires a special hydraulic fluid. The fluid
reservoir is located at the front of the engine compartment on the left
⇒ page 304. The correct fluid level in the reservoir is important for the pow-
er steering to function properly. The hydraulic fluid level is checked at the
Inspection Service. 
Servotronic*
The servotronic system electronically adjusts the power as-
sisted steering.
In vehicles equipped with servotronic power steering the degree of power
assistance ⇒ page 199 is adjusted
electronically according to road speed.
If a fault should occur in the servotronic system, the power steering will still
operate. 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 effort will be required than usual. The fault
should be corrected by a specialised workshop as soon as possible. 
