components in accordance with the
manufacturer's service schedule and according
to your engine.
Otherwise, have them checked by a PEUGEOT
dealer or a qualified workshop.

components as important as those in the
braking system, PEUGEOT selects and offers
very specific products.

are correctly tightened (versions without quick
release terminals) and that the connections are
clean.

"burning" smell. This is perfectly normal.
