2013 Seat Altea warning light

214Vehicle maintenance and cleaning
WARNING
● Wash your vehicle with the ignition switched off.
● Protect your hands and arms from cuts on sharp metal edges when
cleaning the underbody, the inside of the wheel housings etc. Risk of in-
jury.
● Water, ice and salt on the brake system can reduce braking effective-
ness. Risk of accident.
CAUTION
● Never remove dirt, mud or dust if the vehicle surface is dry. Never use a
dry cloth or sponge for cleaning purposes. This could scratch the paintwork
or glass on your vehicle.
● Washing the vehicle in low temperatures: when washing the vehicle
with a hose, do not direct water into the lock cylinders or the gaps around
the doors, rear lid, or sunroof. Risk of freezing.
For the sake of the environment
To protect environment, the vehicle should be washed only in specially pro-
vided wash bays. This prevents toxic, oil-laden waste water entering the
sewerage system. In some places, washing vehicles outside wash bays is
prohibited.
Note
Do not wash the vehicle in direct sunlight. Washing the vehicle with a high pressure cleaner
Be particularly careful when using a high pressure cleaner!
– Always observe the instructions for the high-pressure cleaner,
particularly those concerning the pressure and the spraying
distance.
– Increase the spraying distance for soft materials and painted
bumpers.
– Do not use a high pressure cleaner to remove ice or snow from
windows ⇒ page 215.
– Never use concentrated jet nozzles (“rotating jets”) ⇒ 
.
– After washing, avoid sudden and sharp braking. “Dry” the
brakes by braking several times ⇒ page 202.
WARNING
● Never wash tyres with a concentrated jet (“rotating nozzle”). Even at
large spraying distances and short cleaning times, visible and invisible
damage can occur to the tyres. This may cause an accident.
● Water, ice and salt on the brake system can reduce braking effective-
ness. Risk of accident.
CAUTION
● Do not use water hotter than 60 °C. This could damage the vehicle.
● To avoid damage to the vehicle, keep a sufficient distance from sensitive
materials such as flexible hoses, plastic, soundproofing material, etc. This
is also important for bumpers painted in the colour of the bodywork. The
closer the nozzle is to the surface, the greater the wear on the material. 

218Vehicle maintenance and cleaning
WARNING
Do not apply underseal or anti-corrosion coatings to the exhaust pipes,
catalytic converter or the heat shields on the exhaust system. The heat of
the exhaust system or the engine could cause them to ignite. Risk of fire.

Cleaning the engine compartment
Take special care when cleaning the engine compartment.
Anti-corrosion treatment
The engine compartment and the surface of the power unit are given anti-
corrosion treatment at the factory.
Good corrosion protection is particularly important in winter when the vehi-
cle is frequently driven on salted roads. To prevent the salt corroding the ve-
hicle, the entire engine compartment should be thoroughly cleaned before
and after winter.
Your Technical Services have got the necessary workshop equipment to pro-
vide the correct cleaning and preserving products. For this reason, we rec-
ommend having this work performed by them.
The anti-corrosion protection is usually removed if the engine compartment
is cleaned with grease removing solutions, or if you have the engine
cleaned. On commissioning this work, ensure that all surfaces, seams,
joints and components in the engine compartment are given anti-corrosion
treatment.
WARNING
● When working in the engine compartment, always observe the safety
warnings ⇒ page 233.
● Before opening the bonnet, switch the engine off, apply the hand-
brake firmly and always remove the key from the ignition.
● Allow the engine to cool before you clean the engine compartment.
● Do not clean the vehicle underbody, wheel arches or wheel trims
without protecting your hands and arms. You may cut yourself on sharp-
edged metal parts. Failure to comply could result in injury.
● Moisture, ice and salt on the brake system may affect braking effec-
tiveness. Risk of accident. Directly after washing, avoid sudden and
sharp braking.
● Never touch the radiator fan. It is temperature-controlled and could
start automatically, even when the key is removed from the ignition!
For the sake of the environment
Fuel, grease and oil deposits could be removed when the engine is washed.
The polluted water must be cleaned in an oil separator. For this reason, en-
gine washing should be carried out only by a specialised workshop or a pet-
rol station. 
Vehicle interior maintenance Introduction
The dye used in many modern garments, for example dark jeans, is not al-
ways sufficiently colour-fast. Seat upholstery (material and leather), espe-
cially when light-coloured, may visibly discolour if the dye comes out of
clothing (even when used correctly). This is not an upholstery defect but in-
dicates that the dye in the item of clothing is not sufficiently colour-fast. 

219
Vehicle maintenance and cleaning
The longer stains or dirt remain on the vehicle surfaces, especially the fab-
rics covering the padded upholstery, the more difficult it becomes to clean
and maintain them. If stains and dirt are left for a long time, it may be that
they are impossible to remove.
WARNING
Car-care products may be toxic and hazardous. Using unsuitable car-care
products or, using them in the wrong way, may cause accidents, serious
injury, burns or intoxication.
● Keep your car-care products in their original containers.
● Read the instructions.
● Never keep car-care products in empty food containers, bottles or
other similar containers, other people may confuse them.
● Keep all car-care products out of the reach of children.
● Some products may give off harmful vapours during use. Therefore,
they should be used outdoors in well-ventilated places.
● Never use fuel, turpentine, engine oil, nail-varnish remover or any
other volatile product for washing, maintenance or cleaning. These are
toxic and highly flammable.
WARNING
Unsuitable maintenance and cleaning of vehicle components may impair
proper operation of safety equipment and cause serious injury.
● Maintain and clean vehicle components according to the manufactur-
er's instructions.
● Only use approved or recommended cleaning products.
CAUTION
● Cleaning products which contain solvents have a corrosive effect and
may damage the material irreparably.
● Stains and dirt containing aggressive substances or solvents attack the
material and may damage it irreparably, even when they are cleaned quick-
ly.
● Dirt and stains should not be allowed to dry and should be cleaned as
quickly as possible.
● In the case of stubborn stains, take the vehicle to a specialised work-
shop to avoid damage. 
Treating your upholstery
Checklist
To treat and maintain your seat upholstery, keep the following in mind ⇒ 
:
¥ Before entering the vehicle, close any Velcro fasteners that might
snag on the upholstery or trim fabric. Any open Velcro fasteners may
damage the trim or upholstery fabrics.
¥ To prevent damage, avoid direct contact between sharp decorative
objects and the upholstery and trim fabrics. Decorative objects in-
clude zips, rivets and rhinestones on clothing and belts.
¥ From time to time, clean the dust that gathers in the perforations,
folds and seams so that the surfaces of the seats are not damaged
by its abrasive effect.
¥ Make sure clothes are colour-fast to avoid them running and staining
the upholstery. This is especially important if the upholstery is light
in colour.

CAUTION
If you ignore this checklist, which is important for maintaining your seat up-
holstery, the fabric may be damaged or stained.
● Consult the checklist and carry out the operations it describes.
Note
SEAT recommends you take the vehicle to a specialised workshop to treat
any stains on the upholstery caused by the discolouration of clothing. 
How to clean the upholstery, trim fabrics and Alcantara ®
Cleaning the fabric on heated seats and electrically adjustable seats or
seats with airbag components
It is possible that there are important airbag components and electrical con-
nections inside the driver seat, passenger seat and possibly the outer rear
seats. If these seats and backrests are damaged, or are cleaned and are
treated incorrectly, or if they get wet, the vehicle electric system may be de-
stroyed and the airbag system damaged
⇒ 
.
Electric and heated seats contain components and electrical connections
that may be damaged if the seats are cleaned or incorrectly treated ⇒ 
.
Similarly, damage might be caused at other points in the vehicle's electric
system.
For this reason, bear the following indications in mind for cleaning:
● Do not use high-pressure or steam cleaning equipment or cold aerosols.
● Do not use cream detergents or detergent-based solutions for delicate
garments.
● Prevent the fabric from getting wet at all times.
● Only use cleaning products approved by SEAT.
● If in doubt, take the vehicle to a professional cleaning company. Cleaning the fabric on unheated seats, non-electrically adjustable seats
and seats without airbag components
●
Before using any cleaning products, consult and keep in mind the in-
structions of use, indications and warnings on the container.
● Use a vacuum cleaner (with the brush attachment) on the trim and seat
fabrics, the Alcantara ®
upholstery of the seats and the carpet.
● Do not use high-pressure or steam cleaning equipment or cold aerosols.
● For general cleaning, use a soft sponge or an ordinary lint-free microfi-
bre cloth ⇒ 
.
● Clean Alcantara ®
surfaces with a slightly damp cotton or woollen cloth,
or a standard lint-free microfibre cloth ⇒ 
.
If the dirt on the trim and upholstery fabrics is only superficial, you can use
a standard foam cleaner.
If the upholstery and trim are very dirty, before cleaning them we recom-
mend you find out about the most suitable cleaning options from a profes-
sional cleaning company. If necessary, the cleaning should be carried out
by a specialised company.
Stain removal
When removing stains, it may be necessary to clean the whole surface and
not just the stain itself. Especially if the surface has been dirtied through
normal use. If you only clean the stained area, that part may then look light-
er than the rest. If in doubt, take the vehicle to a professional cleaning com-
pany.
WARNING
If there is a fault in the airbag system, it is likely that the airbag will not
deploy correctly, not deploy at all, or do so unexpectedly, which could
cause serious or fatal injuries.
● Have the system checked immediately by a specialised workshop. 

222Vehicle maintenance and cleaning
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 vehicle 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. 
Cleaning synthetic leather upholstery
Before cleaning the synthetic leather upholstery, bear in mind the following
recommendations ⇒ page 220, Cleaning the fabric on heated seats and
electrically adjustable seats or seats with airbag components
Only use water and neutral cleaning products to clean synthetic leather up-
holstery.
CAUTION
Do not use solvents, floor wax, shoe cream, stain removers or similar prod-
ucts on synthetic leather. These will stiffen the material, causing it to crack
prematurely. Plastic parts and dash panel cleaning
–
Use a clean, damp cloth to clean plastic parts and the dash
panel.
– If this does not provide satisfactory results, use a special sol-
vent-free plastic cleaning product.
WARNING
Never clean the dash panel and the airbag module surface with cleaners
containing solvents. Solvents cause the surface to become porous. If the
airbag triggered, plastic parts could become detached and cause inju-
ries.
CAUTION
Cleaning products which contain solvents will damage the material. 
Wooden trim cleaning*
– Clean the wooden trim with a water-moistened clean cloth.
– If this does not provide satisfactory results, use a gentle soap
solution.
CAUTION
Cleaning products which contain solvents will damage the material. 

Coolant
Engine coolant specifications
The engine cooling system is supplied from the factory with a specially trea-
ted mixture of water and, at least, 40 % of the additive G 13 (TLVW 774 J).
The engine coolant additive is recognisable by its purple colour. This mix-
ture of water and additive gives the necessary frost protection down to
-25 °C (-13 °F) and protects the light alloy parts of the cooling system
against corrosion. It also prevents scaling and considerably raises the boil-
ing point of the coolant.
To protect the engine cooling system, the percentage of additive must al-
ways be at least 40 %, even in warm climates where anti-freeze protection is
not required.
If greater frost protection is required in very cold climates, the proportion of
additive can be increased. However, the percentage of additive should not
exceed 60 %, as this would reduce the frost protection and, in turn, de-
crease the cooling capacity.
When the coolant is topped up, use a mixture of distilled water and, at
least, 40 % of the G 13 or G 12 plus-plus (TL-VW 774 G) additive (both are
purple) to obtain an optimum anticorrosion protection ⇒ 
. The mixture of
G 13 with G 12 plus (TL-VW 774 F), G 12 (red) or G 11 (green-blue) engine
coolants will significantly reduce the anticorrosion protection and should,
therefore be avoided ⇒ 
.
WARNING
If there is not enough anti-freeze in the coolant system, the engine may
fail leading to serious damage.
● Please make sure that the percentage of additive is correct with re-
spect to the lowest expected ambient temperature in the zone in which
the vehicle is to be used.
● When the outside temperature is very low, the coolant could freeze
and the vehicle would be immobilised. In this case, the heating would
not work either and inadequately dressed passengers could die of cold.
CAUTION
The original additives should never be mixed with coolants which are not
approved by SEAT. Otherwise, you run the risk of causing severe damage to
the engine and the engine cooling system.
● If the fluid in the expansion tank is not purple but is, for example,
brown, this indicates that the G 13 additive has been mixed with an inade-
quate coolant. The coolant must be changed as soon as possible if this is
the case! This could result in serious faults and engine damage.
For the sake of the environment
Coolants and additives can contaminate the environment. If any fluids are
spilled, they should be collected and correctly disposed of, with respect to
the environment. 

242Checking and refilling levels
CAUTION
● When mixed with other additives the colour of G12 will change to brown.
If this occurs you should have the coolant changed immediately. Failure to
do so will result in engine damage!
● If a lot of coolant fluid has been lost, wait for the engine to cool down
before putting in cold coolant. This avoids damaging the engine. Large cool-
ant losses are an indication of leaks in the cooling system. See a special-
ised workshop immediately and have the cooling system checked. Other-
wise, there is a risk of engine damage. 
Washer fluid and windscreen wiper blades Topping up washer fluid 
The water for cleaning the windscreen should always be
mixed with washer fluid.
Fig. 165 In the engine
compartment: Cap of
windscreen washer fluid
reservoir. The windscreen washer and the headlight washers
are supplied with fluid
from the windscreen washer fluid container in the engine compartment.
The reservoir is located on the right-hand side of the engine compartment.
Plain water is not enough to clean the windscreen and headlights. We rec-
ommend that you always add a product to the windscreen washer fluid. Ap-
proved windscreen cleaning products exist on the market with high deter-
gent and anti-freeze properties, these may be added all-year-round. Please
follow the dilution instructions on the packaging.
WARNING
Any work carried out in the engine compartment or on the engine must
be carried out cautiously.
● When working in the engine compartment, always observe the safety
warnings ⇒ page 233.
CAUTION
● Never put radiator anti-freeze or other additives into the windscreen
washer fluid.
● Always use approved windscreen cleansing products diluted as per in-
structions. If you use other washer fluids or soap solutions, the tiny holes in
the fan-shaped nozzles could become blocked. 
