Driving the vehicle with a trailer
WARNING
● Adjust your speed to suit the road and traffic conditions.
● An electrical installation that is connected incorrectly or by non-spe-
cialised personnel can prevent the connection of the current to the trailer
and cause faults in the electrical system operation throughout the entire
vehicle, leading to accidents and serious injury.
● All electrical work must be carried out only by the specialised serv-
ices.
● Never directly connect the trailer electrical device to the electrical
sockets of the reverse driving lights or other sources of electrical current.
CAUTION
● Avoid corners, and sudden and sharp braking.
● Once the trailing arm has been removed, place the corresponding cover
on the hole of the fastening point. This prevents dirt from entering the hole
– see the trailer system assembly manual.
Note
● In the event of frequent journeys with a trailer, we recommend also hav-
ing the vehicle inspected in-between the service intervals.
● When connecting and disconnecting the trailer, the handbrake must be
applied.
● For technical reasons, trailers with LED reverse lights cannot be incorpo-
rated into the vehicle anti-theft alarm system. 

Care of the vehicle
Introduction
Regular and suitable care helps to maintain the useful life of your vehicle.
This may also be one of the requirements for upholding any warranty claims
in the event of corrosion or paint defects.
We recommend you use cleaning products from the SEAT Original Accesso-
ries programme available in SEAT dealers. Please follow the instructions for
use on the packaging.
WARNING
● Cleaning products and other materials used for car care can damage
the health if misused.
● Always keep car care materials in a safe place out of the reach of chil-
dren. Risk of poisoning!
● When washing the car during the winter season: Moisture and ice on
the brakes may affect braking efficiency. Risk of accident!
● The ignition must always be switched off when the car is washed.
Risk of accident!
● Do not clean the underside of the car or inside the wheel arches with-
out protecting your hands and arms. You may cut yourself on sharp metal
parts!
● Perfumes and air fresheners inside the vehicle may be harmful to
health at high temperatures in the interior.
CAUTION
● Check the colour stability of your clothing to avoid damaging or visibly
staining the fabric (leather), upholstery and fabric trim.
● Cleaning products containing solvents may damage the material being
cleaned.
● Do not wash the vehicle in direct sunlight. Risk of damage to paintwork.
● If washing the vehicle with a hose in winter, do not direct the jet of water
directly at the locks or at the door seals or bonnet. Risk of freezing.
● Do not use insect sponges or abrasive household sponges, etc. on pain-
ted surfaces. Risk of damage to the painted surface.
● Do not put stickers on the inner side of the window in areas where heat-
ing elements or the aerial is located. This could cause damage and, in the
case of the aerial, radio and navigation system reception faults.
● Do not clean the inner side of the window with sharp objects or corro-
sive or acidic cleaning products. Risk of damaging the heating elements or
the aerial.
● Do not attach any fragrance or air freshener to the dash panel. Risk of
damage to the dash panel.
● To avoid damaging the parking aid system sensors, spray them only
briefly at a minimum distance of 10 cm when cleaning the vehicle with a
high-pressure or steam cleaner.
● Do not clean the roof panel with a brush. Risk of damage to the panel
surface!
For the sake of the environment
● The packaging of the product used to care for your vehicle is hazardous
waste. It must be disposed of according to current local law.
● Only wash the car in special wash bays. 

168Care of the vehicle and cleaning
Note
● Make sure, when washing the vehicle, that the least amount of water
possible enters the lock cylinders.
● We recommend the use of products from the selection of SEAT Original
Accessories to care for the door lock cylinder. 
Wheels
Wheel trims
If you wash the vehicle regularly, you must also thoroughly wash the wheel
trims. Regularly remove any brake abrasion residue and road salt from the
wheels, otherwise the wheel material could be damaged. Repair any dam-
age to the wheel paintwork immediately.
Alloy wheels
After thorough washing, treat the wheels with a protective product for alloy
wheels. Do not use abrasive products to care for the wheels.
WARNING
Moisture, ice and road salt may affect braking efficiency. Risk of acci-
dent!
CAUTION
Heavy dirt on the wheels could lead to their misalignment. This could result
in vibrations being transmitted to the steering wheel that under certain con-
ditions may cause premature steering wear. This dirt must be removed.
Note
We recommend you leave paint damage repairs to a SEAT Authorised Serv-
ice. Underbody sealant
The underside of the vehicle is coated to permanently protect it from chemi-
cal and mechanical agents.
Given that damage to the
protective coating during driving cannot be com-
pletely ruled out, we recommend you check the condition of the protective
coating on the underbody and suspension at regular intervals, preferably
before the start and end of the coldest season of the year.
Authorised SEAT dealers have suitable special products and the necessary
facilities and are aware of the techniques required for their application. We
therefore recommend all touch-up work or additional anti-corrosion meas-
ures be performed by an authorised SEAT dealer.
WARNING
Do not apply underseal or anti-corrosion coatings to the exhaust pipes,
catalytic converter, particulate filter or heat shields on the exhaust sys-
tem. Once the engine has reached operating temperature, these substan-
ces could catch fire. Risk of fire!

Cavity waxing
All cavities on the vehicle exposed to corrosion are permanently factory-pro-
tected by a wax solution .
This wax solution does not need to be checked or touched up. Should wax
run out of the cavities at high ambient temperatures, remove it using a plas-
tic scraper and clean away any stains using lighter fluid. 

169
Care of the vehicle and cleaning
WARNING
Note the regulations concerning safety and environmental protection if
you use lighter fluid to remove the wax. Risk of fire!

Leatherette and upholstery
Leatherette can be cleaned with a damp cloth. If this is not sufficient, these
parts should only be cleaned with solvent-free plastic care and cleaning
products.
Textile covers and trim parts on doors, rear lid, etc. can be cleaned with spe-
cial detergents, e.g. dry foam. A soft sponge or brush or a micro-fibre cloth
for normal cleaning can be used. Use special products to clean the headlin-
er.
Some upholstery, such as dark jeans fabric, is sometimes not durable
enough. This can cause damage or visible colouring of the seat upholstery
(leather or fabric), even under normal conditions of use. This is particularly
applicable to light-coloured seat upholstery (fabric or leather). This is not an
upholstery defect but indicates that the dye in the item of clothing is not
solid enough. 
Heated seat upholstery
Do not clean the seat upholstery with damp products, as this could damage
the seat heating system.
Clean the upholstery with special products, e.g. dry foam, etc. Natural leather
Leather should be looked after from time to time, depending on its use.
Normal cleaning
Moisten a cotton or woollen cloth with water and wipe over the leather sur-
faces.
More stubborn dirt
Do not let the water soak through the leather or penetrate into the seams.
Dry the leather with a soft, dry cloth.
Removing stains
Remove fresh water-based stains such as coffee, tea, juices, blood, etc.
with an absorbent cloth or kitchen roll. Use the special detergent to clean
dried-on stains.
Remove fresh fat-based stains such as butter, mayonnaise, chocolate, etc.
with an absorbent cloth or kitchen roll or with the special detergent if the
stain has not yet soaked through the surface.
Use a grease-dissolving product to treat
dried-in, fat-based stains.
Treat less common stains such as ball-pen and other inks, felt-tip pens, nail
polish, dispersion paint, shoe cream etc. with a special leather stain remov-
er.
Leather care
The leather should be treated twice a year with a special leather-care prod-
uct.
Apply the protective product very sparingly.
Dry the leather with a soft, dry cloth. 

170Care of the vehicle and cleaning
CAUTION
● Avoid exposing leather to direct sunlight for long periods so that it does
not lose its colour. If the car is left for a prolonged period outdoors, cover
the leather so that it does not lose its colour.
● Sharp-edged objects on clothing, such as zips, rivets or belts can leave
permanent scratches and rough marks on the surface of the leather.
● Use of the mechanical steering wheel lock can damage the leather sur-
face of the steering wheel.
Note
● Use a suitable impregnating cream with ultra-violet protection at regular
intervals and after cleaning. The cream will nourish and moisturise the
leather, keep it supple and able to breathe. In addition, it will also help to
protect the surface of the leather.
● Clean the leather every 2 to 3 months and remove fresh dirt as necessa-
ry.
● Preserve the colour of the leather. A special coloured cream for leather
will renew the colour of more heavily worn areas as required.
● Leather is a natural material with specific properties. During vehicle use,
parts of the leather covers may change in appearance, such as folds or wrin-
kles, as a result of their use. 
Seat belts
Keep the seat belts clean!
Wash soiled seat belts with mild, soapy water, removing any heavier dirt
with a soft brush.
Check the condition of all seat belts at regular intervals.
Very soiled belts may not retract properly.
WARNING
● The seat belts should never be removed from the vehicle for cleaning.
● Never clean using chemical products, as chemical detergents destroy
the fabric. Ensure that the seat belts do not come into contact with corro-
sive fluids such as acids, etc.
● If you find any damage to the belt webbing, belt fittings, the belt re-
tractor or the buckle, the belt in question must be replaced by an Official
Service.
● Make sure that the inertia reel seat belts are completely dry before
allowing them to retract.

180Checking and refilling levels
B
(min.) and A (max.). When the engine is hot, it may be
slightly above mark A (max.).
The warning lamp  (red) in the general instrument panel ⇒ page 68, Cool-
ant level and temperature  will appear when the coolant level is too low.
However, we recommend checking the coolant level directly in the tank.
Coolant loss
Any loss of coolant normally indicates a leak. It is not sufficient merely to
top up the coolant. The cooling system should be inspected by an Official
Service without delay.
CAUTION
In the event of a fault that causes the engine to overheat, contact an author-
ised SEAT dealer immediately, as this could damage the engine. 
Topping up coolant
– Switch the ignition off.
– Wait for the engine to cool down.
– Cover the cap on the coolant expansion tank ⇒ Fig. 119 with a
cloth and carefully unscrew the cap.
– Refill the level of coolant.
– Screw the cap on again until it clicks into place.
Do not use a different type of additive if the prescribed anti-freeze additive
is not available, in the event of an emergency. In this case, use only water
and bring the coolant concentration back up to the correct level as soon as
possible at an Official Service. Always top up with unused coolant.
Never fill the coolant tank above mark
A
(max.) ⇒ Fig. 119 Excess coolant
is forced out of the cooling system through the overpressure valve in the fill-
er cap of the expansion tank when the engine heats up.
WARNING
● The anti-freeze additive and, therefore, the entire coolant, are a
health hazard. Avoid touching the coolant. Coolant fumes are also a
health hazard. Store the coolant additive in a safe place out of the reach
of children. Risk of poisoning!
● If splashed into eyes, rinse immediately with clean water and seek
immediate medical advice.
● Seek immediate medical advice if the coolant is accidentally inges-
ted.
CAUTION
If the engine oil cannot be topped up under the given conditions,  do not
drive on. We recommend contacting an authorised SEAT dealer, as this can
damage the engine. 
Radiator fan
The radiator is driven by an electric motor and controlled according to the
temperature of the coolant.
After the engine has been stopped and the ignition switched off, the radia-
tor fan may continue running for around 10 minutes. 

Checking and refilling levels
Brake fluid Checking brake fluid level
Fig. 120 Engine com-
partment: Brake fluid res-
ervoir
The brake fluid reservoir is located in the engine compartment of
the vehicle.
– Switch the ignition off.
– Open the bonnet ⇒ page 173.
– Check the brake fluid level in the reservoir ⇒ Fig. 120. It should
be between the “MIN” and “MAX” marks.
The fluid level drops slightly after a period of time due to automatic com-
pensation for brake pad wear. This is quite normal.
However, if the level goes down noticeably in a short time, or drops below
the “MIN” mark, there may be a leak in the brake system. If the brake fluid
level in the reservoir is too low, this will be indicated by the warning lamp in
the instrument panel 
⇒  page 66, Brake system .
WARNING
If the fluid level has dropped below the MIN mark,  do not drive on.
Risk of accident! Seek professional help.

Changing brake fluid
Brake fluid absorbs moisture. Therefore, it gradually absorbs moisture from
the atmosphere. If the water content in the brake fluid is too high, the brake
system could corrode. The water content also reduces the boiling point of
the brake fluid.
The brake fluid must comply with one of the following standards or specifi-
cations:
● VW 50114
● FMVSS 116 DOT4
WARNING
Heavy use of the brakes may cause a vapour lock if the brake fluid is left
in the brake system for too long. This would seriously affect the efficien-
cy of the brakes and the safety of the vehicle.
CAUTION
Brake fluid damages the vehicle paintwork. 

Windscreen washer
Fig. 121 Engine com-
partment: Windscreen
washer container
The container for the windscreen washer contains the cleaning fluid for the
windscreen or rear window and the headlight washer system. The container
is located in the engine compartment.
The container capacity is approx. 3.5 litres and, in vehicles with windscreen
washer system, approx. 5.4 litres 1)
.
Plain water on its own is not enough to clean the glass and the headlights
properly. We therefore recommend using clean water with a glass cleaning
product to eliminate any stubborn dirt (with an anti-freeze additive in win-
ter).
Although your vehicle has heated windscreen washer jets, anti-freeze
should always be added to the water in winter.
Ethanol can be used where glass cleaner with anti-freeze is unavailable. The
concentration of ethanol must be no greater than 15 %. However, remember
that anti-freeze in this proportion only protects down to -5 °C (23 °F).
CAUTION
● Never mix the windscreen washing water with anti-freeze used for the
cooling system or other additives.
● If the vehicle is equipped with a headlight washer system, only mix a de-
tergent that does not damage polycarbonates with the water.
Note
On topping up the fluid, do not move the filter on the container opening, as
this could contaminate the fluid pipes and, therefore, lead to a windscreen
washer malfunction. 

Checking and refilling levels
Incorrect handling of the vehicle battery could lead to damage. We therefore
recommend all work on the vehicle battery be performed by an authorised
SEAT dealer.
Always be aware of the danger of injury and scalding as well as the risk of
accident or fire when working on the battery and the electrical system.
Therefore, always observe the warnings and follow all general safety pre-
cautions.
WARNING
● Battery acid is very corrosive, therefore, the battery must be handled
with the utmost care. Wear protective gloves and protect your eyes and
skin when handling batteries. The corrosive fumes in the air irritate and
inflame the respiratory tract and cause conjunctivitis. It corrodes tooth
enamel and causes deep, difficult-to-heal wounds when in contact with
the skin. Repeated contact with diluted acids causes skin disease (in-
flammation, ulcers and fissures). When in contact with water, acids dilute
and develop a great deal of heat.
● Do not tilt the battery, as acid could leak out of the vapour vents. Pro-
tect your eyes with glasses or a protective helmet! Risk of blindness! If
acid should splash into the eyes, rinse the affected eye immediately for
several minutes using clean water. Then seek medical care immediately.
● Neutralize any acid splashes on the skin or clothing with soap solu-
tion as quickly as possible and rinse off with plenty of water. If acid is
swallowed by mistake, consult a doctor immediately.
● Keep children away from the battery.
● Hydrogen is released and a highly explosive mixture of gases is gen-
erated when the battery is under charge. Sparks when disconnecting or
releasing cable terminals with the ignition switched on could also cause
an explosion.
● A short circuit is produced if the battery terminals are bridged, e.g.
using metal objects, cables, etc. Possible consequences of a short cir-
cuit: melting of lead plates, battery explosion and fire, splashing acid.
WARNING (Continued)
● The following is forbidden while working on the battery: fire and open
flames, smoking and activities that could produce sparks. Avoid causing
sparks when handling cables or electrical apparatus. Risk of injury in the
event of large sparks.
● Before working on the electrical system, you must switch off the en-
gine, the ignition and all electrical components and disconnect the cable
from the negative terminal (-) of the battery. To change a bulb, simply
switch off the corresponding light.
● Never charge a frozen or thawed out battery. Risk of explosion and
acid burns! Replace a frozen battery.
● Never use the jump leads on batteries in which the electrolyte level is
too low. Risk of explosion and acid burns.
● Never use a damaged battery. Risk of explosion! Replace a damaged
battery immediately.
CAUTION
● Never disconnect the battery when the ignition is switched on, as the
electrical system (electronic components) of the vehicle could be damaged.
When disconnecting the battery from the vehicle electrical system, discon-
nect its negative terminal (-) first. Only then may the positive terminal (+) be
disconnected.
● When connecting the battery, connect the positive terminal (+) first. On-
ly then may the negative terminal (-) be connected. The battery cables must
never be connected to the wrong battery terminals. Risk of burning the elec-
trical installation.
● Make sure the battery acid does not come into contact with the body-
work. Risk of paintwork damage.
● Do not expose the battery to direct sunlight to protect it from ultraviolet
radiation. 

The tyre pressure monitoring system uses ABS sensors to compare the revo-
lutions and the circumference of each wheel. Should the circumference of
any wheel change, the warning lamp  in the general instrument panel
⇒ page 72 will light up and an audible warning will be heard.
Tyre circumference may change if:
● Tyre pressure is too low
● Tyre structure is damaged ●
Vehicle load not evenly distributed
● Wheels on one axle are subjected to greater load, (e.g. driving with trail-
er, uphill, downhill)
● Snow chains are fitted
● The temporary spare wheel is fitted
● One wheel on the axle has been changed
Basic system settings
Should the tyre pressure change or if one or more wheels are changed or
the position of the wheel on the vehicle is changed, e.g. changing round the
front and rear wheels, or where a warning lamp lights up when driving, the
system must be adjusted as follows:
● Inflate all tyres to the prescribed pressures ⇒ page 188.
● Switch the ignition on.
● Hold the  
⇒ Fig. 128 button down for at least 2 seconds. The warn-
ing lamp  will light up when the button is pressed. The system memory is
also deleted and a new calibration system will begin, which is indicated by
an audible warning before the warning lamp switches off .
● If the warning lamp  remains lit and does not switch off, not even once
the basic setting process is complete, this indicates a fault in the system.
Contact an Official Service.
The warning lamp  lights up
If the pressure on at least one tyre is significantly lower than the pressure
set by the driver, the warning lamp  ⇒
