Checking and refilling levels
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 230.
● When the engine is warm or hot, the cooling system is pressurised!
Do not unscrew the cap on the expansion tank when the engine is hot.
This is a burn injury risk.
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. 170 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. 

Bulb change General notes
Before changing any bulb, first turn off the failed component.
Do not touch the bulb glass. Fingerprints vaporise in the heat, causing a re-
duction in the bulb life and condensation on the mirror surface, thus reduc-
ing efficiency.
A bulb should only be replaced by one of the same type. The type is inscri-
bed on the bulb, either on the glass part or on the base.
It is highly recommended to keep a box of spare bulbs in the vehicle. At the
very least, the following spare bulbs, which are essential for road safety,
should be kept in the vehicle. Main headlights

On this type of headlight, the bulb changes must be made by the SEAT dealer, given that
complex elements must be removed from the vehicle and a reset must be made on the
automatic control system incorporated.
2) The Xenon bulbs discharge 2.5 times the light flux and have an average lifespan of 5 times
more than that of halogen bulbs, this means that, except due to unusual circumstances,
there is no need to change the bulbs for the whole life of the vehicle.
3) Electronically controlled single filament bulb for Stop/side bulbs. If the bulb blows it will
not work in either position or Stop.

Note
● Depending on weather conditions (cold or wet), the front lights, the fog
lights, the tail lights and the turn signals may be temporarily misted. This
has no influence on the useful life of the lighting system. By switching on
the lights, the area through which the beam of light is projected will quickly
be demisted. However, the edges may continue to be misted.
● Please check at regular intervals that all lighting (especially the exterior
lighting) on your vehicle is functioning properly. This is not only in the inter-
est of your own safety, but also that of all other road users.
● Due to the difficulty in accessing some of the bulbs, any replacement
work should be done by a SEAT dealer. However, the following is a descrip-
tion of how to change the lamps except for the fog lights* and interior
lamps. 
