B = minimum
Oil change: according to the manu-
facturer's servicing schedule.
- Dipstick. Never fill past the maxi- mum mark A.
- Oil level gauge on the instrument panel.
Viscosity selection In all cases, the oil selected must meet the manufacturer's require-ments.

Oil filter Change the filter regularly according to the servicing schedule. Used oilPrevent used oil from coming into prolonged contact with the skin. Do not dispose of used oil into drains or onto the ground.
To maintain the reliability of engines and emission control systems, theuse of additives in the engine oil isprohibited. Brakes and clutch Checking the brake and clutch fluid level:
- The level should always be above
the DANGER mark on the reser-
voir.
- If the level drops substantially, contact a PEUGEOT dealer imme-
diately.
Fluid change
- must be carried out according to the manufacturer's servicing sche- dule.
- use fluids approved by the manu- facturer, which fulfil DOT 4 stan-dards. Cooling system Use the fluid approved by the manu-
facturer. When the engine is warm, the tem- perature of the coolant is controlledby the engine fan. Because this fancan operate with the ignition keyremoved and because the coolingsystem is pressurised, wait for atleast one hour after the engine hasstopped before carrying out anywork. In the event of a breakdown and to avoid any risk of burns, slacken thecap to the first notch to release thepressure. When the pressure hasdropped, remove the cap and top upthe level.
