GLOW PLUGS (JTD engines)When the ignition key is turned to MAR, the dial warning light comes on and go out when the
glow plugs have reached the pre-established temperature.
Start the engine as soon as the warning light has gone out.
WARNINGWith a high environment temperature, the warning light may turn on for an imper-
ceptible length of time. For versions/markets where applicable, the warning light flashes for approx.
30 seconds after starting the engine, which means that there is a fault in the glow plug warming
system, contact Alfa Romeo Authorized Services.
c
WATER IN THE FUEL OIL FILTER (JTD engines)The warning light switches on with fixed light when driving, to indicate the presence of water in
the fuel oil filter.
The presence of water in the fuel circuit may cause serious damage to
the entire injection system and cause irregular engine operation. If warn-
ing light
c
comes on the dial, contact Alfa Romeo Authorized Services
as soon as possible to have the system relieved. Should the above warning in-
dication come one immediately after topping up, water has probably been poured
into the tank: turn the engine off immediately and contact Alfa Romeo Autho-
rized Services.

SELESPEED GEARBOX FAILURETurning the ignition key to MAR, the warning light on the cluster shall come on and then go off af-
ter about 4 seconds. If the warning light stays on, it indicates that a fault has been detected in the Se-
lespeed gearbox; at the same time, the buzzer beeps intermittently for 4 seconds to draw the atten-
tion of the driver. Contact Alfa Romeo Authorised Services as soon as possible to remove the fault.Q-SYSTEM AUTOMATIC GEARBOX FAILURETurning the ignition key to MAR, the warning light on the cluster shall come on and then go off
after about 4 seconds. If the warning light stays on or turns on when travelling, it indicates over-
heated gearbox oil (glowing steadily) or a gearbox fault (flashing).
Warning light glowing steadily: it indicates that the gearbox oil has reached the maxi-
mum established temperature.
To make oil cooling down, stop the car, move the lever to Por Nand let the engine idle until the
warning light goes out. Resume driving without demanding high performance from the engine. If
the warning light comes on again, it is necessary to stop again with the engine idling until it goes
out again. If the interval between one lighting up of the warning light and next is below 15 minutes,
you are advised to stop the car, turn the engine off and wait for the engine-gearbox unit to cool down
completely. Contact Alfa Romeo Authorised Services as soon as possible.
Warning light flashing: it indicates a fault in the automatic gearbox.
The automatic control system provides an emergency programme. Under these circumstances,
you are advised to stop the car and turn the engine off; in fact, the next time the engine is started,
the self-diagnostic system could cut off the fault which will however be memorised. Conversely, if
the fault remains (warning light flashing), it is necessary to select the gears manually as if driving
a car with mechanical gearbox, bearing in mind that the only two speeds available are the 2
ndand
4
thgear. Contact Alfa Romeo Authorised Services as soon as possible.
