The tyre pressure should be 60 kPa (0.6 bar / 9 PSI) all round. 
To improve driving the pressure on the rear tyres can be 
reduced to 40 kPa (0.4 bar/5.6 PSI). The maximum tyre 
pressure is 100 kPa (1,0 bar/14 PSI).

Clean the air intake grille in the engine cover behind the 
driver’s seat.

Open the engine cover.

Check that the cooling intake is free from leaves, grass and 
dirt.

Check the air duct, located on the inside of the engine cover, 
ensure it is clean and does not rub against the cooling air 
intake.

A blocked cooling intake will interfere with the cooling of the 
engine, which can damage the engine.
