The weight distribution of a loaded trailer
with an unladen vehicle is very unfavourable.

Checking and refilling levels
CAUTION
● Do not mi x
cleaning products recommen-
ded by SEAT with other products. This could
lead to flocculation and may block the wind-
screen washer jets.
● When topping up service fluids, make abso-
lutely c
ertain that you fill the fluids into the
correct reservoirs. Using the wrong fluids
could cause serious malfunctions and engine
damage!
● Not having windscreen wiper fluid reduces
vis
