Brakes and clutch level:
Ð The level should always be
between the DANGER and MAX
marks on the reservoir.
Ð If the level drops substantially, con- tact a PEUGEOT dealer imme-
diately.
Fluid change:
Ð must be carried out according to the manufacturer's servicing schedule.
Ð use fluids recommended by the manufacturer, which fulfil DOT4standards.
Note: the brake fluid is noxious and
very corrosive. Avoid any contactwith the skin. Coolant level Use the fluid recommended by the
manufacturer. When the engine is warm, the tem- perature of the coolant is controlledby the engine fan. Because this fan
can operate with the ignition off andbecause the cooling system is pres-surised, wait for at least one hourafter the engine has stopped beforecarrying out any work. To avoid any risk of burns, slackenthe cap to the first notch to releasethe pressure. When the pressure hasdropped, remove the cap and top upthe level. Used products Do not dispose of used oil, brake fluid or coolant down drains or on theground. Power steering fluid level Open the reservoir with the engine
cold. The level should always beabove the MINI mark, close to theMAXI mark.
