WARNING
● Failure to observe warning lamps and warning messages can result in
serious personal injury or damage to your vehicle.
● The risk of an accident increases if your vehicle breaks down. Use a
warning triangle to draw the attention of other road users in order to pre-
vent danger to third parties.
● The engine compartment is a dangerous area! Before you open the
bonnet to work on the engine or in the engine compartment, you must
switch the engine off and allow it to cool to reduce the risk of scalding or
other injuries. Read and observe the relevant warnings ⇒ page 217.
Note
● The appropriate warning lamp for a fault will light up in vehicles without
warning or information messages in the display.
● In vehicles with warning or information texts on the screen, the appro-
priate warning lamp for a fault will light up and a warning or information
message will also appear on the screen. 
Warning symbols
There are red warning symbols (priority 1) and yellow warning sym-
bols (priority 2) Warning reports, Priority 1 (red)
If one of these faults occurs, the warning lamp will flash or light up and will
be accompanied by three audible warnings. This is a danger warning. Stop
the vehicle and switch off the engine. Check the fault and correct it. Obtain
professional assistance if necessary. If several priority 1 faults are detected at the same time, the symbols will be
displayed one after the other for about 2 seconds at a time and will contin-
ue until the fault is corrected.
No menus will be shown in the display for the duration of a priority 1 warn-
ing message.
Examples of priority 1 warning messages (red)
●
Brake system symbol  with the warning message STOP BRAKE FLUID
SERVICE MANUAL or STOP BRAKE FAULT SERVICE MANUAL .
● Coolant symbol  with the warning message STOP SEE COOLANT IN-
STRUCTION MANUAL.
● Engine oil pressure symbol  with the warning message STOP ENGINE
OIL PRESSURE LOW! INSTRUCTION MANUAL .
Warning reports, Priority 2 (yellow)
If one of these faults occurs, the warning lamp lights up, and is accompa-
nied by one audible warning. Check the corresponding function as soon as
possible although the vehicle may be used without risk.
If several priority 2 warning messages are detected at the same time, the
symbols are displayed one after the other for about 2 seconds at a time. Af-
ter a set time, the information text will disappear and the symbol will be
shown as a reminder at the side of the display.
Priority 2 warning messages will not be shown until all Priority 1 warning
messages have been dealt with!
Examples of priority 2 warning messages (yellow): 1)
● Fuel warning light with the information text PLEASE REFUEL.
● Windscreen washer fluid symbol  with the information text REFILL
WINDSCREEN WASHER FLUID . Top up the washer fluid level. 

● The temporary spare wheel is fitted.
● The wheel on one axle is changed.
Tyre pressure adjustment
Following the modification to tyre pressure or after changing one or more
wheels, the button ⇒  fig. 50 must be kept pressed while the ignition is on
until an acoustic signal is heard and the warning lamp goes out.
If the wheels are under excessive load (for example, driving with a trailer or
heavy load), the tyre pressure must be increased to the recommended value
for a full load (see the sticker on the inside of the fuel flap). If the tyre moni-
tor system button is pressed down, the new tyre pressures are confirmed.
The tyre pressure warning lamp  lights up
If the tyre pressure of one or more wheels is much lower than the value set
by the driver, the tyre control warning lamp lights up ⇒ 
.
The tyre pressure warning lamp  flashes
If the tyre pressure warning lamp flashes, this indicates a fault. Go to the
nearest specialist workshop.
WARNING
● When the tyre pressure warning lamp lights up, reduce speed imme-
diately and avoid any sudden manoeuvre or braking. Stop when possible,
and check the tyre pressure and status.
● The driver is responsible for maintaining correct tyre pressures. For
this reason, tyre pressure must be regularly checked.
● Under certain circumstances (for example, when driving in a sports-
like manner, in winter conditions or on a dirt track) the tyre warning lamp
may light up or function incorrectly.
Note
If the battery is disconnected, the yellow warning lamp  lights up after
turning the ignition on. This should turn off after a brief journey. 

WARNING
● Before opening the bonnet, read and observe the warnings on
⇒ page 217.
● If the brake warning lamp does not go out, or if it lights up when driv-
ing, the brake fluid level ⇒ page 229, Brake fluid in the reservoir is too
low. Risk of accident. Stop the vehicle and do not drive on. Obtain techni-
cal assistance.
● If the brake warning lamp  lights up together with the ABS warning
lamp , the control function of the ABS could be out of action. This could
cause the rear wheels to lock quickly when you brake. This could cause
the rear to break away. Risk of skidding. Stop the vehicle and seek tech-
nical assistance.

Handbrake 
This lamp lights up when the handbrake is applied. If you drive faster than 6 km/h with the handbrake on, the following mes-
sage will appear on the instrument panel display 1)
: HANDBRAKE ON. You will
also hear an acoustic warning signal ⇒ page 173. 
Bulb defect 
The warning lamp lights up when a bulb in the vehicle's ex-
terior lighting is defective.
The warning lamp  lights up when a bulb in the vehicle's exterior lighting
(e.g. left-hand main beam) is defective. The instrument panel displays the following message
1)
: LEFT FULL BEAM
FAULTY. 
Engine oil pressure 
If this warning lamp is red it indicates that the engine oil
pressure is too low.
If this warning symbol starts to flash, and is accompanied by three audible
warnings, switch off the engine and check the oil level. If necessary, add
more oil ⇒ page 220.
The instrument panel displays the following message 1)
: STOP ENGINE OIL
PRESSURE INSTRUCTION MANUAL .
If the symbol flashes although the oil level is correct, do not drive on. The
engine must not even run at idle speed. Obtain technical assistance.
Checking the oil level 
If the warning lamp is yellow  the engine oil level should be checked as
soon as possible. Top up the oil ⇒ page 222 at the next opportunity.
Oil level sensor faulty* 
If the  yellow warning lamp flashes, take the vehicle to a specialised
workshop to have the oil level sensor checked. Until then it is advisable to
check the oil level every time you refuel. 

Driving
If the engine does not start immediately, switch the starter off after 10 sec-
onds and try again after half a minute. If the engine still does not start, the
fuel pump fuse should be checked ⇒ page 250, Fuses.
WARNING
● Never start or run the engine in unventilated or closed rooms. The ex-
haust fumes contain carbon monoxide, an odourless and colourless poi-
sonous 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 fol-
low the instructions in ⇒ page 263, Jump-starting.
For the sake of the environment
Do not warm-up the engine by running the engine with the vehicle station-
ary. Start off immediately, driving gently. This helps the engine reach oper-
ating temperature faster and reduces emissions. Starting diesel 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 start-
er to turn the engine on.
– Turn the ignition key to the starting position.
– Turn the ignition key to position ⇒ fig. 117 1
. The indicator
lamp  will light for engine pre-heating.
– When the warning lamp turns off, turn the key to position 2
to
start the engine. Do not press the accelerator.
– Let go of the ignition key as soon as the engine starts, the start-
er motor must not be allowed to run on with the engine.
When starting a very cold engine, it may be a little noisy for the first few sec-
onds until oil pressure has built up in the hydraulic valve compensators.
This is quite normal, and no cause for concern.
If there are problems starting the engine, see the ⇒ page 263.
Glow plug system for the diesel engine
To avoid unnecessary discharging of the battery, do not use any other major
electrical equipment while the glow plugs are pre-heating.
Start the engine as soon as the glow plug warning lamp ⇒ page 83 goes
out.
Starting the engine after the fuel tank has been completely run dry
If the fuel tank has been completely run dry, it may take longer than normal
(up to one minute) to start the engine after refuelling with diesel fuel. This is
because the system must eliminate air first. 

190Driving and the environment
WARNING (Continued)
● 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 change down into a lower gear or range (depending on the type of
transmission). This makes use of engine braking and relieves the brakes.
● Never let the brakes “drag” by applying light pressure. Continuous
braking will cause the brakes to overheat and the braking distance will
increase. Apply and then release the brakes alternately.
● Never let the vehicle run with the engine switched off. The braking
distance is increased considerably when the brake servo is not active.
● If the brake fluid loses its viscosity and is subjected to heavy use, va-
pour bubbles can form in the brake system. This reduces the efficiency of
the brakes.
● Non-standard or damaged front spoilers could restrict the airflow to
the brakes and cause them to overheat. Before purchasing accessories
please observe the relevant instructions ⇒ page 208, Technical modifi-
cations.
● If a brake circuit fails, the braking distance will be increased consider-
ably. Contact a specialised workshop immediately and avoid unnecessa-
ry journeys.

Exhaust gas purification system Catalytic converter*
To maintain the useful life of the catalytic converter
– Use only unleaded petrol with petrol engines, as lead damages
the catalytic converter.
– Do not let the fuel get too low in the tank. –
For engine oil changes, do not replenish with too much engine
oil ⇒ page 222, Topping up engine oil .
– Never tow the vehicle to start it, use jump leads if necessary
⇒ page 263.
If you notice misfiring, uneven running or loss of power when the vehicle is
moving, reduce speed immediately and have the vehicle inspected at the
nearest specialised workshop. In general, the exhaust gas warning lamp
will light up when any of the described symptoms occur ⇒ page 77. If this
happens, unburnt fuel can enter the exhaust system and escape into the en-
vironment. The catalytic converter can also be damaged by overheating.
WARNING
The catalytic converter reaches very high temperatures! There is a risk of
fire.
● Never park where the catalytic converter could come into contact with
dry grass or flammable materials under the vehicle.
● Do not apply additional underseal or anti-corrosion coatings to the
exhaust pipes, catalytic converter or the heat shields on the exhaust sys-
tem. These materials could catch fire when the vehicle is being driven.
CAUTION
Never run the fuel tank completely dry because the irregularity of the fuel
supply may cause ignition problems. This allows unburnt fuel to enter the
exhaust system, which could cause overheating and damage the catalytic
converter.
For the sake of the environment
Even when the emission control system is working perfectly, there may be a
smell of sulphur from the exhaust gas under some conditions. This depends
on the sulphur content of the fuel used. Quite often the problem can be
solved by changing to another brand of fuel. 

192Driving and the environment
Drive anticipating the traffic situation
A vehicle uses most fuel when accelerating. When you anticipate the situa-
tion, you have to brake less often and, thus, accelerate less. If it is possible,
let the vehicle roll with a gear engaged, for example, if you see a red light
ahead. The braking effect achieved in this way helps to reduce the wear of
brakes and tyres; emissions and fuel consumption are reduced to zero (dis-
connection due to inertia).
Change gear early to save energy
An effective way of saving fuel is to change up quickly through the gears.
Running the engine at high rpm in the lower gears uses an unnecessary
amount of fuel.
Manual gearbox: Change from first to second gear as quickly as possible.
We recommend that, whenever possible, you change to a higher gear upon
reaching 2000 rpm. Follow the “recommended gear” indication that ap-
pears on the instrument panel ⇒ page 62.
Avoid driving at high speed
We advise you not to drive at the top speed permitted by the vehicle. Fuel
consumption, exhaust emissions and noise levels all increase very rapidly
at higher speeds. Driving at moderate speeds will help to save fuel.
Avoid idling
It is worthwhile switching off the engine when waiting in a traffic jam, at lev-
el crossings or at traffic lights with a long red phase. The fuel saved after
only 30 - 40 seconds is greater than the amount of fuel needed to restart
the engine.
The engine takes a long time to warm up when it is idling. Mechanical wear
and pollutant emissions are also especially high during this initial warm-up
phase. It is therefore best to drive off immediately after starting the engine.
Avoid running the engine at high speed.
Periodic maintenance
Periodic maintenance work guarantees that, before beginning a journey,
you will not consume more than the required amount of fuel. A well-serviced engine gives you the benefit of
improved fuel efficiency as well as maxi-
mum reliability and an enhanced resale value.
A badly serviced engine can consume up to 10% more fuel than necessary.
Avoid short journeys
To reduce the consumption and emission of polluting gases, the engine and
the exhaust filtration systems should reach the optimum service tempera-
ture.
With the engine cold, fuel consumption is proportionally higher. The engine
does not warm up and fuel consumption does not normalise until having
driven approximately four kilometres. This is why we recommend avoiding
short trips whenever possible.
Maintain the correct tyre pressures
Bear in mind that keeping the tyres at an adequate pressure saves fuel. If
the tyre pressure is just one bar too low, fuel consumption can increase by
as much as 5%. Due to the greater rolling resistance, under-inflation also
increases tyre wear and impairs handling.
The tyre pressures should always be checked when the tyres are cold.
Do not use winter tyres all year round as they increase fuel consumption by
up to 10%.
Avoid unnecessary weight
Every kilo of extra weight will put up the fuel consumption, so it is worth
checking the luggage compartment occasionally to make sure that no un-
necessary loads are being transported.
A roof rack is often left in place for the sake of convenience, even when it is
no longer needed. At a speed of 100-120 km/h your vehicle will use about
12% more fuel as a result of the extra wind resistance caused by the roof
rack even when it is not in use. 

193
Driving and the environment
Save electricity
The engine activates the alternator, which produces electricity. With the
need for electricity, fuel consumption is also increased. Because of this, al-
ways turn off electrical components when you do not need them. Examples
of components that use a lot of electricity are: the fan at high speeds, the
rear window heating or the seat heaters*.
Note
● If you vehicle has Start-Stop, it is not recommended to disconnect this
function.
● It is recommended to close the windows when driving at more than 60
km/h
● Do not drive with your foot resting on the clutch pedal, as the pressure
can make the plate spin, more fuel will be used and it can burn the clutch
plate lining, causing a serious fault.
● Do not hold the vehicle on a hill with the clutch, use the foot brake or
hand brake, using the latter to start. The fuel consumption will be lower and
you will prevent the clutch plate from being damaged.
● On descents, use the engine brake, changing to the gear that is more
suitable for the slope. The fuel consumption will be lower and the brakes
will not suffer. 
