2012 Seat Exeo ST ABS

198Intelligent technology
The traction control system (ASR) helps the car to start moving, accelerate
and climb a gradient in slippery conditions where this may otherwise be dif-
ficult or even impossible.
How it works
The ASR works automatically, i.e. without the driver's involvement. With the
aid of the ABS sensors , the ASR monitors the speed of the driven wheels
⇒ page 196. If the wheels start to spin, the engine speed is reduced auto-
matically to match the amount of grip available. The system is active across
the entire speed range.
The ASR works in conjunction with the ABS. If a failure occurs in the ABS,
the ASR will also stop working.
In general, the ASR should be left switched on at all times. It should only be
switched off manually in particular circumstances where a certain amount of
wheel slip may be desirable. Examples:
● when driving with snow chains
● when driving in deep snow or on loose surfaces
● when rocking the vehicle backwards and forwards to free it.
The ASR should be switched on again afterwards as soon as possible.
Note
To ensure that the ASR works properly, all four wheels must be fitted with
identical tyres. The difference in size of the wheels may lead to an unde-
sired reduction in engine power. Also see ⇒  page 255.Brakes
General notes
New brake pads
New brake pads do not provide optimal performance during the first
200 km; first they must be “run in”. However, the reduced braking capacity
may be compensated by pressing on the brake pedal a little harder. Avoid
overloading the brakes during run-in.
Wear
The rate of wear on the brake pads depends a great deal on how you drive
and the conditions in which the vehicle is operated. Negative factors are, for
instance, city traffic, frequent short trips or hard driving with abrupt starts
and stops.
Wet roads or road salt
In certain conditions, such as in heavy rain, or after washing the vehicle or
driving through water, the full braking effect can be delayed by moisture (or
in winter by ice) on the discs and brake pads. In this case the brakes should
be dried by pressing the brake pedal several times.
The effectiveness of the brakes can also be temporarily reduced if the vehi-
cle is driven for some distance without using the brakes when there is a lot
of salt on the road in winter. In this case, the layer of salt on the brake discs
and pads has to wear off before braking.
Corrosion
There may be a tendency for corrosion to form on the discs and dirt to build
up on the brake pads if the vehicle is used infrequently or the brakes are
not used very often.
If the brakes are not used frequently, or if rust has formed on the disks, it is
advisable to clean off the pads and disks by braking firmly a few times at a
moderately high speed ⇒

Vehicle maintenance and cleaning
CAUTION
● Brushes should only be used to clean the carpet and floor mats! Other
fabrics may be damaged if cleaned with a brush.
● If cream detergents or detergents for delicate garments are applied with
a damp cloth or sponge, they may, for example, leave rings when dry be-
cause of the tensioactive components they contain. Generally, such rings
are very difficult or almost impossible to remove.
CAUTION
● Do not let water soak into Alcantara ®
under any circumstances.
● Do not use leather cleaning products, solvents, wax polish, shoe cream,
stain removers or similar products on Alcantara ®
.
● Never use brushes for cleaning damp material as they could damage the
surface. 
Cleaning and maintenance of natural leather upholstery
Consult a professional cleaning workshop if you have any doubts on clean-
ing and maintaining the leather equipment in your car.
Maintenance and treatment
Nappa natural leather is delicate because it has no additional protective
layer.
● After cleaning, regularly apply a conditioner with sun-screen and im-
pregnating action. These products nourish the leather, soften it and make it
more breathable, as well as re-hydrating it. They also provide it with a pro-
tective film.
● Clean the leather every two or three months and remove stains as they
appear.
● Treat the leather regularly (about twice a year) with a suitable mainte-
nance product. ●
Apply as few cleaning and maintenance products as possible, always
using a dry, lint-free cotton or woollen cloth. Do not apply cleaning and
maintenance products directly to the leather.
● Remove recent ball-point pen and ink stains, lipstick, shoe cream and
similar stains as soon as possible.
● Maintain the colour of the leather. To do this, use a special cream espe-
cially coloured for leather to achieve the same overall colour, if necessary.
● Afterwards, go over it with a soft cloth.
Cleaning
SEAT recommends using a slightly damp cotton or woollen cloth for general
cleaning purposes.
Generally, the leather should never be soaked at any point, nor should wa-
ter penetrate the seams.
Before cleaning the leather upholstery, bear in mind the following recom-
mendations ⇒ page 224, Cleaning the fabric on heated seats and electrical-
ly adjustable seats or seats with airbag components.CAUTION
● On no account use solvents, wax polish, shoe cream, stain removers or
similar materials on leather.
● If the stain remains on the leather for long, it will soak in and be impos-
sible to remove.
● In the event of spilt liquids, dry immediately with an absorbent cloth to
prevent the liquid penetrating through the leather or seams.
● If the car is left standing in the sun for long periods, the leather should
be protected against direct sunlight to prevent it from fading.
Note
The leather will usually change colour slightly with use. 

Checking and refilling levels
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 fluid must be collected and disposed of according the
applicable regulations. The SEAT Technical Service network has the neces-
sary 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. 

246Checking 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 304.
Wear eye protection
Battery acid is very corrosive and caustic. Wear protective
gloves and eye protection!
Fires, sparks, open flames and smoking are prohibited! 

Wheels and tyres
Significant tyre pressure loss
The tyre symbol  is displayed and indicates that the tyre pressure
of at least one tyre is insufficient.
– Stop the vehicle.
– Switch the engine off.
– Check the tyre(s).
– Change the wheel if necessary. 
Tyre pressure monitoring (RKA+)*
The tyre pressure monitor display on the instrument panel
indicates if the pressure is too low.
Fig. 189 Detailed view of
the centre console: But-
ton for the tyre pressure
monitoring system The tyre pressure monitoring system makes use of the ABS sensors to com-
pare the rolling circumference and the frequency characteristics of the
wheels. If the rolling circumference or frequency characteristic changes on
one or more wheels, the tyre pressure warning lamp  will light up. The
fault will also be indicated by a warning buzzer. The position of the affected
tyre will also be shown (if only one tyre is affected) on the centre display of
the instrument panel.
The rolling circumference and frequency characteristics can change if:
●
the tyre pressure is too low.
● the tyre has suffered structural damage.
● the wheels or the inflation pressures have been changed without initial-
ising the system (see Adjusting the tyre pressure settings).
● there is a greater load on the wheels of one axle (e.g. if you are carrying
more passengers or luggage).
● the road surface under the left wheels is different to the road surface un-
der the right wheels for a long period.
● when driving with snow chains.
Adjusting the tyre pressure settings (initialising the tyre pressure
monitoring system)
After any incident regarding the wheels of your vehicle, e.g. after modifying
the tyre pressure ⇒ page 253 or after changing or swapping wheels
⇒ page 253 you should - with the vehicle at a standstill and the engine run- ning - press ⇒ Fig. 189. The yellow warning lamp  will light up. Hold the
button down for 2 seconds until the warning lamp goes out and an acoustic
warning is given. You can now release the button.
If the wheels are subjected to extreme stress (e.g. heavy load), the tyre
pressure must be increased to the recommended value for the maximum
load (see the adhesive label on the inside of the fuel tank flap) and then
initialise the system. 
