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!

Coolant level* / temperature  (red)
The warning lamp lights up if the coolant temperature is too
high or if the coolant level is too low.
There is a fault if:
● The warning symbol does not go out again after a few seconds.
● The warning lamp lights up or flashes while the vehicle is moving, and
three acoustic warning signals ⇒ 
are emitted.
This means that either the coolant level is too low or the coolant tempera-
ture is too high.
Coolant temperature too high
The instrument panel displays the following message 1)
: CHECK COOLANT IN-
STRUCTION MANUAL ⇒  page 224.
First look at the coolant temperature gauge. The coolant temperature is too
high if the needle is over the warning area on the dial. Stop the vehicle,
switch the engine off and wait for it to cool down. Check the coolant level.
If the coolant level is correct, the overheating may be caused by a malfunc-
tion of the radiator fan. Check the radiator fan fuse and have it replaced if
necessary ⇒ page 250.
If the warning lamp lights up again after driving on for a short distance,
stop the vehicle and switch the engine off . Contact an Authorised Service
Centre or a specialised workshop.
Coolant level too low
The instrument panel displays the following message 1)
: STOP CHECK COOL-
ANT INSTRUCTION MANUAL.
First look at the coolant temperature gauge. If the needle is in the normal
range, top up with coolant at the earliest opportunity ⇒ 
.
WARNING
● If your vehicle is immobilised for technical reasons, move it to a safe
distance from traffic. Turn the engine off, turn the hazard lights on and
place the warning triangle.
● Never open the bonnet if you can see or hear steam or coolant escap-
ing from the engine compartment. Risk of scalding. Wait until you can no
longer see or hear escaping steam or coolant.
● The engine compartment is a dangerous area! Before carrying out any
work in the engine compartment, switch off the engine and allow it to
cool down. Always note the corresponding warnings ⇒ page 217.

operational to approx. -24°C, provided you use winter-grade diesel which is
safe to -15°C.
However, if the fuel has waxed to such an extent that the engine will not
start at temperatures of under -24°C, simply place the vehicle in a warm
place for a while.
CAUTION
Do not mix fuel additives (thinners or similar products) with diesel fuel. 
Working in the engine compartment Safety instructions on working in the engine compartment
Any work carried out in the engine compartment or on the
engine must be carried out cautiously.
Before starting any work on the engine or in the engine compart-
ment:
1. Switch off the engine and remove the key from the ignition.
2. Apply the handbrake.
3. Move the gear lever to neutral or the selector lever to position P.
4. Wait for the engine to cool down.
5. Keep children away from the vehicle.
6. Raise the bonnet ⇒ page 219. You should not do any work in the engine compartment unless you know ex-
actly how to carry out the jobs and have the correct tools! Have the work car-
ried out by a specialised workshop if you are uncertain.
All service fluids and consumables, e.g. coolant, engine oil, spark plugs
and batteries, are under constant development. SEAT provides a constant
flow of information to the Authorised Service Centres concerning modifica-
tions. For this reason, we recommend you to have service fluids and con-
sumables replaced by an Authorised Service Centre. Please observe the rel-
evant instructions
⇒ page 208. The engine compartment of the vehicle is a
hazardous area ⇒ 
.
WARNING
All work on the engine or in the engine compartment, e.g. checking and
refilling fluids, involves the danger of injury and scalding as well as the
risk of accident or fire.
● Never open the bonnet if you see steam, smoke or coolant escaping
from the engine compartment. Otherwise, there is a risk of sustaining
burns. Wait until no more steam or coolant is emitted, then allow the en-
gine to cool before carefully opening the bonnet.
● Switch off the engine and remove the key from the ignition.
● Apply the handbrake and move the gear lever to neutral or selector
lever to position P.
● Keep children away from the vehicle.
● Never touch hot engine parts. There is a risk of burns.
● Never spill liquids on a hot engine or on a hot exhaust gas system.
This is a fire hazard.
● Avoid causing short-circuits in the electrical system, particularly at
the points where the jump leads are attached ⇒ page 264. The battery
could explode. 

WARNING (Continued)
● Never touch the radiator fan. It is temperature controlled and could
start automatically, even when the engine has been switched off and the
key removed from the ignition!
● Do not unscrew the cap on the expansion tank when the engine is
hot. If the coolant is hot, the cooling system will be pressurised!
● Protect face, hands and arms by covering the cap with a large, thick
cloth to protect against escaping coolant and steam.
● Always make sure you have not left any objects, such as cleaning
cloths and tools, in the engine compartment.
● If you have to work underneath the vehicle, you must use suitable
stands additionally to support the vehicle, there is a risk of accident!. A
hydraulic jack is insufficient for securing the vehicle and there is a risk of
injury.
● If any work has to be performed when the engine is started or with
the engine running, there is an additional, potentially fatal, safety risk
from the rotating parts, such as the drive belts, alternator, radiator fan,
etc., and from the high-voltage ignition system. You should also observe
the following points:
–Never touch the electrical wiring of the ignition system.
– Ensure that jewellery, loose clothing and long hair do not get trap-
ped in rotating engine parts. Danger of death. Before starting any
work remove jewellery, tie back and cover hair, and wear tight-fitting
clothes.
– Never accelerate with a gear engaged without taking the necessary
precautions. The vehicle could move, even if the handbrake is ap-
plied. Danger of death.
● If work has to be carried out on the fuel system or on electrical com-
ponents, you must observe the following safety notes in addition to the
above warnings:
–Always disconnect the battery. The vehicle must be unlocked when
this is done, otherwise the alarm will be triggered.
– Do not smoke.WARNING (Continued)
– Never work near naked flames.
– Always have a fire extinguisher on hand.
CAUTION
When topping up service fluids, make sure not to mistake them. Using the
wrong fluids could cause serious malfunctions and engine damage!
For the sake of the environment
Service fluids leaks are harmful to the environment. For this reason you
should make regular checks on the ground underneath your vehicle. If you
find spots of oil or other fluids, have your vehicle inspected in a specialised
workshop. 

Coolant
Coolant specifications
Coolant is a mixture of water and at least 40% coolant addi-
tive. The cooling system must be filled with a mixture of water and at least 40 %
of our coolant additive G 12+ or an additive with the specification TT-VW
774 F (it is dyed purple). This mixture provides the necessary freeze protec-
tion down to -25°C and protects the alloy parts of the cooling system
against corrosion. It also prevents scaling and raises the boiling point of the
coolant.
The concentration of coolant must always be at least 40% - even if freeze
protection is not required.
If greater freeze protection is required in very cold climates, the proportion
of the antifreeze additive G 12+ can be increased. However, the percentage
of coolant additives should not exceed 60%, as this would reduce the
freeze protection. It would also reduce the cooling effect. A mixture with
60% additive will give antifreeze protection to approx. -40°C.
WARNING
● The coolant additive is toxic. There is a toxic risk. Always keep the
coolant additive in the original container which should be stored out of
the reach of children. The same applies to coolant which you have
drained off.
● The coolant additive G 12+ must be added in sufficient quantities to
provide anti-freeze protection at the coldest ambient temperatures that
can be expected. At extremely cold outside temperatures, the coolant
could freeze, causing the vehicle to breakdown. As the heater would not
work either, there is a risk of freezing to death.
CAUTION
● Other additives may give considerably inferior corrosion protection. The
resulting corrosion in the cooling system can lead to a loss of coolant, caus-
ing serious damage to the engine.
● The coolant additive G 12+ (purple) can be mixed with the additive G 12
(red) or G 11. Never mix G12 (red colour) with G 11. 
Checking the coolant level and topping up 
The correct coolant level is important for fault-free function-
ing of the engine cooling system.
