yep... just pop the bonnet, check all fluid levels from time to
time (engine oil, power steering, coolant, brake fluid,
washer).
Checking tyre pressure is recommended at least every 2 weeks. I've
seen ppl who never check anything from 1 service interval till the
next (20k+ km)... coolant empty, engine oil below minimum and tyres
with so little pressure and excessive wear on the sides.
