FUEL LEVEL GAUGE WITH
RESERVE INDICATOR
This shows the amount of fuel left in the
fuel tank.
The warning light
K(A-fig. 76) turns
on to indicate that approx. 7 litres of fuel
are left in the tank.
IMPORTANTUnder certain conditions
(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 condition falls within the operation
logics of the electronic control circuit to
avoid highly unstable readings due to
swaying of the fuel when travelling.
IMPORTANTRefuelling shall always be
performed with engine off and ignition key
atSTOP. If the engine is off but the key is
atMAR, a wrong fuel level could tem-
porarily be indicated. This is due to the inter-
nal system control logic and cannot be con-
sidered as a system malfunctioning.
ENGINE COOLANT FLUID
TEMPERATURE GAUGE WITH
MAXIMUM TEMPERATURE
WARNING LIGHT
This shows the temperature of the
engine coolant fluid and begins when the
fluid temperature exceeds approx. 50°C.
Normally the pointer should be towards
the middle of the scale. If the pointer
reaches the higher temperatures of the
scale (red area) the request for vehicle
performance should be decreased.
The turning on of the
u(B-fig. 76)
warning light(on some versions together
with the message shown on the reconfig-
urablemultifunction display) indicates that
the coolant fluid temperature is too high;
in this case, stop the engine and contact
Alfa Romeo Authorised Services.IMPORTANTThe temperature of the
engine coolant may rise towards the max-
imum values (red zone) when the vehicle
is driven at low speeds, especially when
the ambient air temperature is high. In
this case it is advisable to stop the vehicle
and switch off the engine for a few min-
utes, after which the journey can be
resumed, preferably at a higher speed.

WARNING LIGHTS
IMPORTANTThe number of warning lights present depends on the type of engine and equipment with which the car is fitted.
x
LOW BRAKE FLUID AND/OR HANDBRAKE ON
Turning the ignition key to MARthe warning light on the dial turns on, but it should go off after
approx. 4 seconds.
The warning light turns on when the level of the brake fluid in the reservoir falls below the min-
imum level, due to a possible leak in the circuit and when the handbrake is engaged.
If the
xwarning light turns on when travelling check that the hand-
brake is not engaged. If the warning light stays on with the handbrake
off (on some versions together with the message + symbol shown on
the reconfigurable multifunction display) stop the car immediately and contact
Alfa Romeo Authorised Services.
u
HIGH ENGINE COOLANT FLUID TEMPERATURE
Turning the ignition key to MARthe warning light on the dial turns on, but it should go off after
approx. 4 seconds.
The warning light turns on (on some versions together with the message + symbol shown on
the reconfigurable multifunction display) when the engine is overheated. If it turns on when trav-
elling, stop the car, leaving the engine on and slightly accelerated to further activate the circula-
tion of the coolant fluid.
If the warning doesn’t go off within 2 or 3 minutes, stop the car immediately and contact Alfa
Romeo Authorised Services.

AUTOMATIC TWO-ZONE CLIMATE CONTROL SYSTEM
(for versions/markets where applicable)
To start the system (fig. 99):
- turn the knob rings to set the required
temperatures (driver’s side - passenger’s
side).
- press the
AUTObutton.
IMPORTANTThe climate control sys-
tem makes it possible to personalise the
temperatures required on the two side with
a maximum difference of 7°C between the
driver’s side and the passenger’s side.
IMPORTANTThe climate control com-
pressor only works with the engine running
and an outside temperature above 4°C.
With an outside tempera-
ture below 4°C the climate
control compressor is un-
able to work. It is therefore unad-
visable to use the inside air re-cir-
culation feature
vwith a low
temperature as the windows might
mist over quickly.
For further details about the system and
how to make the best use of it, read the
instructions given in pages that follow.
A0A0203b
fig. 99
The coolant used for the
climate control system is
R134a which meets cur-
rent regulations and does not harm
the environment in the event of ac-
cidental spillage.
Absolutely avoid the use of oth-
er fluids which are incompatible
with the system components.
GENERAL
The car is fitted with a two-zone climate
control system, controlled by an electronic
control unit which makes it possible to sep-
arately adjust the air temperature on the dri-
ver’s side and on the passenger’s side. To
obtain optimum temperature control in the
two areas of the passenger compartment,
the system has an outside sensor, a pas-
senger compartment sensor and a two-zone
sun ray sensor.

HI function
(highest heating power - fig. 102)
This is turned on setting on the display a
temperature above 32,5°C, and can be ac-
tivated independently from the driver’s or
passenger’s side or both; this setting brings
the system to the “monozone” mode and
is shown on both displays.
This function can be engaged when re-
quiring to heat the passenger compartment
as quickly as possible, exploiting the maxi-
mum potential of the system.
This function uses the maximum temper-
ature of the coolant fluid, while air distribu-
tion and fan speed are controlled according
to the system settings.
This function is unadvisable with
the engine cold to prevent admit-
ting air that is not warm enough to
the passenger compartment.
All manual settings are possible with this
function on.
To switch the system off, simply turn the
ring of knob (2) or (6) of the temperature
set to a value below 32,5°C; the opposite
display will show 32,5°C.

perature adjustment.

STARTING PROCEDURE
FOR JTD VERSIONS
1) Make sure the handbrake is
engaged.
2) Set the gearshift lever to neutral.
3) Turn the ignition key to MAR.The
reconfigurable multifunction display will
show the
mwarning light.
4) Wait for the
mto turn off, which
takes place sooner, the warmer the
engine. With the engine very warm the
light might stay on for such a short time
as to pass unnoticed.
5) Fully depress the clutch pedal.
6) Turn the ignition key to AV Vas
soon as the
mwarning light has gone
out. Waiting too long, makes the warming
work of the glow plugs useless .IMPORTANTThe electric devices
that absorb a high amount of energy (cli-
mate control, rearscreen heating, etc.) are
cut off automatically during starting.
If the engine does not start at the first
attempt, move the ignition key to STOP
before repeating starting.
If starting is difficult (with the Alfa
Romeo CODE system working properly),
do not insist with prolonged attempts.
Only use an auxiliary battery if the cause
is due to low battery charge. Never use a
battery charger to start the engine.
WARMING THE ENGINE
– Drive off slowly, at medium revs with-
out accelerating abruptly.
– Do not drive at full performance for
the initial kilometres of the journey. Wait
until the engine coolant temperature
reaches 50-60 °C.
