Winter driving
Diesel can thicken in winter.
Winter-grade diesel
When using summer-grade diesel fuel, difficulties may be experienced at
sub-zero temperatures because the fuel thickens due to wax separation. For
this reason, winter-grade diesel fuel is available in some countries during
the cold months. It can be used at temperatures as low as -22 °C.
In countries with different climatic conditions the diesel fuel generally sold
has different temperature characteristics. Check with the Technical Services
or filling stations in the country concerned regarding the type of diesel fuels
available.
Filter pre-heater
Your vehicle is fitted with a fuel filter glow plug system, making it well
equipped for operation in winter. This ensures that the fuel system remains
operational to approx. -24 °C, provided you use winter-grade diesel that 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. Bonnet
Work in the engine compartment
Extra caution is necessary when working on components in
the engine compartment. Always be aware of the danger of injury and scalding as well as the risk of
accident or even fire when working in the engine compartment (e.g. when
checking and refilling fluids). Always observe the warnings listed below
and follow all general safety precautions. The engine compartment of the
vehicle is a potentially hazardous area ⇒ 
WARNING
● Switch the ignition off.
● Remove the ignition key.
● Apply the handbrake firmly.
● If your vehicle is equipped with a manual gearbox, place the gear lev-
er in neutral. If you are driving an automatic vehicle, place the selector
lever in position P.
● Wait for the engine to cool down.
● Children should not be allowed to approach the engine compartment.
● Never spill liquids used for vehicle operation on the engine compart-
ment, as these may catch fire (e.g. the antifreeze in coolant).
● Take care not to cause short circuits in the electrical system, especial-
ly when working on the battery.
● Never touch the radiator fan while the engine is hot, as the fan could
start up suddenly.
● Never open the expansion tank when the engine is hot. The cooling
system is under pressure. 

Before opening the bonnet make sure that the windscreen wiper
arms are not lifted away from the glass. Otherwise the paint may
be damaged.
– Lift the bonnet slightly ⇒ 
.
– Press the release catch under the bonnet upwards ⇒ Fig. 180.
This will release the arrester hook under the bonnet.
– Open the bonnet.
The bonnet is held in position by a gas-filled strut.
WARNING
Never open the bonnet if you see steam or drips of coolant being re-
leased from the engine compartment. Failure to comply could result in
burns. Wait until no steam or coolant can be seen before opening the
bonnet.
 Closing the bonnet
–
To close the bonnet, push it down until it overcomes the spring
pressure.
– Let the bonnet engage in the locking part. Do not force it ⇒ 
.
WARNING
● For safety reasons the bonnet must always be completely closed
when the vehicle is moving. Therefore, after closing the bonnet, always
check that the locking element is properly engaged. This is the case if
the bonnet is flush with the adjacent body panels.
● Should you notice that the bonnet is not safely secured when the ve-
hicle is moving, stop the vehicle immediately and close the bonnet. Fail-
ure to do so could result in an accident.

Engine oil General notes
The engine comes with a special, multi-grade oil that can be used all year
round.
Because the use of high-quality oil is essential for the correct operation of
the engine and its long useful life, when topping up or changing oil, use on-
ly those oils that comply with VW standards.
The specifications (VW standards) set out in the following page should ap-
pear on the container of the service oil; when the container displays the
specific standards for petrol and diesel engines together, it means that the
oil can be used for both types of engines. 
Safety FirstOperating instructionsPractical TipsTechnical Specifications

238Checking and refilling levels
We recommend that the oil change, indicated in the Maintenance Pro-
gramme, be performed by a Technical Service or a specialised workshop.
The correct oil specifications for your engine are listed in the ⇒ page 238,
Oil properties.
Service intervals
Service intervals can be flexible (LongLife service) or fixed (dependent on
time/distance travelled).
If the PR code that appears on the back of the “Maintenance Programme”
booklet is PR QI6, this means that your vehicle has the LongLife service pro-
grammed. If it lists the codes QI1, QI2, QI3, QI4 or QI7, the interval service
is dependent on time/distance travelled.
Flexible service intervals (LongLife service intervals*)
Special oils and processes have been developed which, depending on the
characteristics and individual driving profiles, enable the extension of the
oil change service (LongLife service intervals).
Because this oil is essential for extending the service intervals, it must only
be used observing the following indications:
● Avoid mixing it with oil for fixed service intervals.
● Only in exceptional circumstances, if the engine oil level is too low
⇒  page 239 and LongLife oil is not available, it is permitted to top up
(once) with oil for fixed service intervals (up to a maximum of 0.5 litres).
Fixed service intervals*
If your vehicle does not have the “LongLife service interval” or it has been
disabled (by request), you may use oils for fixed service intervals, which al-
so appear in ⇒  page 238, Oil properties. In this case, your vehicle must be
serviced after a fixed interval of 1 year/15 000 km (10 000 miles)(whatever
comes first) ⇒ Booklet Maintenance Programme. ●
In exceptional circumstances, if the engine oil level is too low
⇒  page 239 and you cannot obtain the oil specified for your vehicle, you
can put in a small quantity of oil conforming to the specification ACEA A2 or
ACEA A3 (petrol engines) or ACEA B3 or ACEA B4 (diesel engines) (up to 0.5
l).
Vehicles with diesel particulate filter*
All Exeo vehicles with a diesel engine have a diesel particulate filter and
must only be filled with VW 507 00 engine oil, which has a low level of soot
formation. Using other types of oil will cause a higher soot concentration
and reduce the life of the DPF. Therefore:
● Avoid mixing this oil with other engine oils.
● Only in exceptional circumstances, if the engine oil level is too low
⇒  page 239 and you cannot obtain the oil specified for your vehicle, you
can use a small quantity of oil (once) conforming to the VW 506 00,
VW 506 01, VW 505 00, VW 505 01 or ACEA B3/ACEA B4 specification. (up
to 0.5 l). 

WARNING
Do not drive unless you have good visibility through all windows!
● The ignition must not be switched on while the front wiper arms are
in a raised position. The wipers would return to their park position and
damage the paintwork on the bonnet.
● To prevent smearing on the windscreen, the wiper blades should be
cleaned regularly using a window cleaner solution. If the wiper blades
are very dirty (e.g. insects etc.), they should be cleaned using a sponge
or cloth. Failure to do so could result in an accident.
● For safety reasons, the wiper blades should be changed once or twice
a year.
CAUTION
● Damaged or dirty windscreen wipers could scratch the windscreen.
● Never use fuel, nail varnish remover, paint thinner or similar products to
clean the windows. This could damage the windscreen wiper blades.
● Never move the windscreen wiper or windscreen wiper arm manually.
This could cause damage.
● Do not pull the windscreen wipers forward unless they are in the service
position. Otherwise the bonnet could be damaged. Changing the rear wiper blade
A good rear wiper blade is essential for clear rear vision.
Damaged wiper blades should be replaced immediately.

Topping up and changing the brake fluid
It is best to have the brake fluid changed by a professional. Brake fluid absorbs moisture. Therefore, in the course of time it will absorb
water from the air. If the water content in the brake fluid is too high, the
brake system could corrode. In addition, the boiling point of the brake fluid
will be considerably reduced. This could adversely affect the braking ability
in certain circumstances.
For this reason the brake fluid must be changed periodically.
Your vehicle's Service Plan will tell you when the brake fluid has to be re-
newed.
We recommend you have the brake fluid changed as part of a regular In-
spection Service at a Technical Service. They are familiar with the procedure
and have the necessary special tools and spare parts as well as the proper
facilities for disposing of the old fluid.
Be sure to always use the correct brake fluid. Only use brake fluid that ex-
pressly meets VW 501 14 standards.
You can buy VW 501 14 standard brake fluid in a SEAT dealership or SEAT
Official Service. If none is available, use only high quality brake fluid that
meets DIN ISO 4925 CLASS 4 standards, or USA Standards FMVSS 116 DOT
4.
Using any other kind of brake fluid or one that is not of a high quality may
affect operation of the brake system and reduce its effectiveness. Never use
a brake fluid if the container does not state that it complies with VW 501 14,
DIN ISO 4925 CLASS 4 standards, or USA standards FMVSS 116 DOT 4.WARNING
● Brake fluid must always be kept closed in its original container. Keep
out of the reach of children. Failure to comply could result in poisoning.
● If the brake fluid is left in the system for too long and the brakes are
subjected to heavy use, vapour bubbles may form in the brake system.
This would seriously affect the efficiency of the brakes and the safety of
the vehicle, leading to the risk of accident.
CAUTION
Please note that brake fluid will attack the paintwork on contact.
For the sake of the environment
The brake pads and brake fluid must be collected and disposed of accord-
ing the applicable regulations. The SEAT Technical Service network has the
necessary equipment and qualified personnel for collecting and disposing
of this waste material. 
Vehicle battery General notes
All work on batteries requires specialist knowledge.
The battery is virtually maintenance-free and is checked in the Inspection
Services.
We recommend replacing the battery after 5 years. 
Safety FirstOperating instructionsPractical TipsTechnical Specifications

248Checking and refilling levels
Disconnecting the battery
If the battery is disconnected, some of the vehicle's functions will become
inoperative (e.g. electric windows). These functions will require resetting af-
ter the battery is reconnected. For this reason, the battery should only be
disconnected from the vehicle's electrical system when absolutely necessa-
ry.
Long periods of non-use
The battery will gradually lose its charge because certain electrical equip-
ment continues to draw current even when the ignition is off. If you park the
vehicle for long periods of time in winter you should take the battery out of
the vehicle and store it in a place protected from frost. This way it will not
freeze and become damaged. At warm outside temperatures it is sufficient
to disconnect the negative terminal of the battery. Even when the battery is
not connected you should charge it from time to time.
Winter operation
The battery is drained more in cold weather, which means that the starting
power is reduced. For this reason, have the battery checked and charged if
necessary before the start of winter.
Replacing the battery
A replacement battery must have the same capacity, voltage and current rat-
ing. It must also have the same dimensions as the original, factory-fitted
battery and have sealed caps. The SEAT batteries which have been specially
developed fulfil the maintenance, performance and safety specifications for
your vehicle.
We recommend you use maintenance-free batteries.
WARNING
● All work on batteries requires specialist knowledge. If work is re-
quired on the battery, this should be performed by a Technical Service or
specialised workshop. Danger of caustic burns and explosion!
● The battery must not be opened. Never try to change the battery's liq-
uid level. Explosive gas is released from the battery that could cause an
explosion.
CAUTION
● The battery holder and clamps must always be correctly secured.
● Before starting any work on the battery, always observe the warnings
listed under ⇒ 
.
For the sake of the environment
 Batteries contain toxic substances including sulphuric acid and lead.
Therefore, they must be disposed of in line with environmental regulations
and must not be disposed of with ordinary household waste. Make sure dis-
connected batteries cannot tip over. Sulphuric acid could be spilt! 
Important safety warnings for handling a vehicle battery
The battery is located at the back of the engine compartment ⇒ page 306.

General notes
Avoiding damage
– If you have to drive over a kerb or similar obstacle, drive very
slowly and at a right angle.
– Keep grease, oil and fuel off the tyres.
– Inspect the tyres regularly for damage (cuts, cracks or blisters,
etc.). Remove any foreign objects embedded in the treads.
Storing tyres
– When you remove the tyres, mark them in order to maintain the
same direction of rotation when they are installed again.
– When removed, the wheels and/or tyres should be stored in a
cool, dry and preferably dark location.
– Store tyres in a vertical position if they are not fitted on wheel
rims.
New tyres
New tyres have to be run in.
The tread depth of new tyres may vary, according to the type and make of
tyre and the tread pattern. Concealed damage
Damage to tyres and rims is often not readily visible. If you notice unusual
vibrations or the vehicle pulling to one side, this may indicate that one of
the tyres is damaged. The tyres should be checked immediately by a Techni-
cal Service.
Tyres with directional tread pattern
An arrow on the tyre sidewall indicates the direction of rotation on tyres with
directional tread. Always observe the direction of rotation indicated when
fitting the wheel. This guarantees optimum grip and helps to avoid aqua-
planing, excessive noise and wear.
WARNING
● New tyres do not have maximum grip during the first 500 km
(300 miles). Drive particularly carefully to avoid possible accidents.
● Never drive with damaged tyres. This may cause an accident.
● If you notice unusual vibrations or if the vehicle pulls to one side
when driving, stop the vehicle immediately and check the tyres for dam-
age.

Checking tyre pressure
The correct tyre pressure can be seen on the sticker on the
inside of the fuel tank flap. 1. Read the required tyre inflation pressure from the sticker. The values refer to Summer tyres. For Winter tyres, you must add
0.2 bar to the values given on the sticker. 

Tyre pressure warning lamp on
When you switch on the ignition, the tyre pressure warning lamp  will
light up for about 2 seconds. There is a fault in the system if the indicator
stays on permanently after switching on the ignition. The instrument panel
also display TMPS (Tyre Pressure Monitoring System). Please contact the
nearest specialised workshop as soon as possible.
The tyre pressure warning lamp  lights up if the tyre pressure on one or
more wheels is significantly lower than the tyre pressure setting which was
confirmed by the driver ⇒ 
.
WARNING
● If the tyre pressure warning lamp lights up  you must slow down
immediately and avoid any severe braking or steering manoeuvres. Stop
the vehicle as soon as possible and check the tyres and their pressure.
● The driver is responsible for maintaining correct tyre pressures.
Therefore, the tyre pressure must be regularly checked.
● Under certain conditions (e.g. driving at high speeds, on ice and snow
or on poor road surfaces) the tyre pressure warning lamp  may not light
up immediately or not at all.
● Please ask your Technical Service or specialised workshop whether
run-flat tyres can be used on your vehicle. Fitting this type of tyre in an
undue manner could lead to your driving licence being taken away from
you. Furthermore, it may led to damage to the vehicle or, under certain
circumstances, may cause accidents.
● If you change normal tyres for run-flat tyres or vice versa, the control
unit must be reprogrammed by the Technical Service or a specialised
workshop.
Note
If you did not press the button for the tyre pressure monitoring system to
confirm a new tyre pressure setting after making changes to the tyre pres-
sures or changing one or more wheels, the warning lamp  may light up
although the tyre pressures are correct. In this case, stop the vehicle as
soon as possible and, after examining the tyres, press the button for the
tyre pressure monitoring system. 

256Wheels and tyres
Wheel balance
The wheels on new vehicles are balanced. However, various factors encoun-
tered in normal driving can cause them to become unbalanced, which re-
sults in steering vibration.
Unbalanced wheels should be rebalanced, as they otherwise cause exces-
sive wear on steering, suspension and tyres. A wheel must also be reba-
lanced 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
alignment checked by a Technical Service.
WARNING
There is a serious danger of accidents if a tyre bursts during driving!
● The tyres must be replaced at the latest when the tread wear indica-
tors are worn ⇒ page 255. Failure to do so could result in an accident.
Worn tyres do not grip well at high speeds on wet roads. There is also a
greater risk of aquaplaning.
● At continuously high speeds, a tyre with insufficient pressure flexes
more. This causes it to overheat. This can cause tread separation and tyre
blow-out. Risk of accident. Always observe the recommended tyre pres-
sures.
● If tyres show excessive wear, you should have the running gear
checked by a Technical Service.
● Keep chemicals such as oil, fuel and brake fluid away from tyres.
● Damaged wheels and tyres must be replaced immediately!
For the sake of the environment
Under-inflated tyres will increase fuel consumption. Run-flat tyres*
Run-flat tyres allow you to continue driving even with a
punctured tyre, in the majority of cases.
In vehicles that are factory-fitted with run-flat tyres 1)
the loss of tyre
pressure is indicated on the instrument panel.
Driving with run-flat tyres (emergency running)
– Leave the ESC/ASR on (Electronic Stability Control), or switch it
on ⇒  page 71.
– Continue driving carefully and slowly (80 km/h (50 mph) maxi-
mum).
– Avoid sudden manoeuvres and sharp turns.
– Avoid driving over obstacles (for example kerbs) or potholes.
– Pay attention if the ESC/ASR activates often, if smoke comes
from the tyres or there is a smell of rubber, the vehicle vibrates
or there are clattering noises. If any of these occur, stop the ve-
hicle.
The run-flat tyres have a tag on the side of the tyre, with the description:
“DSST”, “Eufonia”, “RFT”, “ROF”, “RSC”, “SSR” or “ZP”.
The sides of this type of tyre are reinforced. When the tyres lose air they are
supported on the sides (emergency driving).
The loss of pressure in the tyre is shown on the instrument panel. You can
then drive a maximum of 80 km (50 miles) and if the circumstances are fa-
vourable (for example, low load), even more. 
1)
Depending upon version and country.

257
Wheels and tyres
The damaged tyre should be changed as soon as possible. The rim should
be checked in a specialised workshop to detect possible damage and re-
place it if necessary. We recommend you contact Technical Service. If more
than one tyre is being used under emergency conditions, this reduces the
distance which can be travelled.
Starting driving in emergency conditions
When loss in tyre pressure is displayed on the instrument panel, this means
that at least one tyre is being driven in emergency conditions ⇒ 
.
End of emergency operation
Do not drive on if:
● smoke is coming from one of the tyres,
● there is a smell of rubber,
● the vehicle vibrates,
● there is a rattling noise.
When is it no longer possible to continue driving even using run-flat tyres?
● If the Electronic Stability Control (ESC) does not function.
● If the tyre pressure monitoring system* does not work.
● If one of the tyres has been severely damaged in an accident, etc. If a
tyre has been badly damaged there is a risk that parts of the tread can be
thrown off and cause damage to the fuel lines, brake pipes or fuel filler.
● It is also advisable to stop driving if severe vibrations occur, or if the
wheel starts overheating and gives off smoke.
WARNING
When driving in emergency conditions, the driving quality of the vehicle
is considerably impaired.
● The maximum permitted speed of 80 km/h (50 mph) is subject to
road and weather conditions. Please observe legal requirements when
doing so.
● Avoid sharp turns and rapid manoeuvres, and brake earlier than usu-
al.
● Avoid driving over obstacles (for example kerbs) or potholes.
● If one or more tyres are being driven in emergency conditions, the
driving quality of the vehicle is impaired and there is a risk of accident.
Note
● The run-flat tyres do not “deflate” on losing pressure because they are
supported on the reinforced sides. Therefore defects in the tyre cannot be
detected with a visual inspection.
● Snow chains must not be used on front tyres used in emergency condi-
tions. 
New tyres and wheels
New tyres and wheels have to be run in.
The tyres and wheel rims are an essential part of the vehicle's design. The
tyres and rims approved by SEAT are specially matched to the characteris-
tics of the vehicle and make a major contribution to good road holding and
safe handling ⇒ 
.
Tyres should be replaced at least in pairs and not individually (i.e. both front
tyres or both rear tyres together). A knowledge of tyre designations makes it
easier to choose the correct tyres. Radial tyres have the tyre designations
marked on the sidewall, for example: 
