E - Fuel gauge and reserve
warning light
This shows the amount of fuel left in
the fuel tank.
0Tank empty;
1Tank full (see "Refuelling" paragraph
in this section).
This warning light comes on to indicate
that about 9 litres of fuel are left in the
tank.
IMPORTANTUnder certain condi-
tions (heavy slopes, for instance) the
reading on the gauge may differ from the
actual amount of fuel in the tank and
changes in level may be indicated late.
This is part of the operating logic of the
electronic control circuit to avoid highly
unstable readings due to swaying of the
fuel when travelling.F - Engine coolant temperature
gauge and maximum temperature
warning light (fig. 85)
This shows the temperature of the en-
gine coolant fluid and begins when the
fluid temperature exceeds about 50°C.
The pointer should normally be towards
the middle of the scale. If the pointer
reaches the higher temperature values
the request for vehicle performance
should be decreased.
The illumination of this warning light in-
dicates an excessive temperature of the
engine cooling fluid. In this case, stop the
car and contact Alfa Romeo Authorized
Services.IMPORTANT The temperature of the
engine coolant may rise towards the maxi-
mum values by obstruction or dirt on the
outer part of the engine cooling radiator.
In this case you are advised to inspect
and remove any obstructions and have
the outside of the radiator washed as
soon as possible.

To gain access to relays on the bracket
set behind the left headlight (fig. 91),
remove the cover (A-fig. 90) after
turning the fastening pins (B).Circuits operated by relays are the fol-
lowing (fig. 91):
– Brown base relay: additional heater
(JTD versions)
– Black base relay: engine cooling radi-
ator relay, high speed (JTD versions).
