HYDRAULIC SYSTEM OIL(fig. 13)
The oil level of the Selespeed system
should be carried out with the car on a lev-
el surface and with the engine stopped and
cold.
To check the level, proceed as follows:
– turn the ignition key to MAR;
– disconnect the breather tube and re-
move the cap (A) checking that the level
corresponds with the MAXmark on the dip-
stick of the actual cap;
– if the level is below the MAXmark, top
up with oil until reaching the correct level;
– after screwing the cap back on, insert
the breather tube completely on the cap
spout and turn the ignition key to STOP.fig. 13

Do not add oil with dif-
ferent characteristics than
those of the oil already in
the system.
The oil level should never exceed the
MAXmark on the dipstick on the COLD
side, if the level is checked cold and on the
HOTside if the level is checked with the
gearbox/differential unit hot.

The level should be between the MINand
MAXmarks of the sector identified by the
word COLD(+40°C).
WARNINGAfter long journeys with the
gearbox/differential unit very hot, the oil
level should be between the MINand
MAXmarks of the sector identified by the
word HOT(+80°C).
