2006 Alfa Romeo 156 coolant temperature

GETTING TO KNOW YOUR CAR
115
For more detailed information on the sys-
tem and how to make the best use of it,
read the instructions given in the following
pages.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 other
fluids which are incompatible with
the system components.fig. 100

GENERALThe car is equipped with a two-zone cli-
mate control system, controlled by an elec-
tronic control unit which makes it possible
to separately adjust the air temperature on
the driver’s side and on the passenger’s side.
To obtain optimum temperature control in
the two areas of the passenger compart-
ment, the system has an outside sensor, a
passenger compartment sensor and a two-
zone sun ray sensor.
On some versions, the system is integrated
with an incipient misting sensor installed be-
hind the internal rearview mirror, which is
able to “monitor” a predefined area of the
windscreen inner surface which can auto-
matically act on the system to prevent or re-
duce misting, through a series of operations
such as: opening air recirculation, enabling
compressor, air flow to the windscreen, fan
speed sufficient for demisting; and, in case
of heavy misting, enabling the
MAX
-DEF
function.
The climate control com-
pressor cannot work when
the outside temperature is less
than 2°C. Therefore, it is recom-
mended that the internal air recir-
culation function
v
is not used
when the outside temperature is
low, as the windows could mist
over rapidly.
WARNING

CORRECT USE OF THE CAR
190
WARNINGOn the 2.0 JTS version,
keep the brake pedal pressed when starting
the engine. As the brake pedal stiffens if it
is pressed repeatedly with the engine off. In
this situation, to allow the engine to be
started, it is necessary to increase the pres-
sure exerted on the pedal itself.PROCEDURE FOR JTD VERSIONS1)Make sure the handbrake is engaged.
2)Move the gearshift lever to neutral.
3)Turn the ignition key to the MARpo-
sition. The warning light
m
on the instru-
ment cluster will turn on.
4)Wait for the
m
warning light to go
off, which will depend on how warm the en-
gine is. With the engine very hot the warn-
ing light may stay on for such a short time
that it is not noticed.
5)Fully depress the clutch pedal.
6)Turn the ignition key to AV Vas soon
as the
m
warning light goes off. Waiting
too long would make the glow plug heating
work pointless.WARNINGThe electric devices that ab-
sorb much energy (air conditioner,
rearscreen heating, etc.) are disengaged au-
tomatically during engine starting.
If the engine does not start at the first at-
tempt, move the ignition key back to the
STOPposition before repeating starting.
If starting is difficult (with the Alfa Romeo
CODE system efficient), do not insist with
prolonged attempts.
Only use an auxiliary battery if it is noted
that the cause is due to low charge of the
car’s battery. Never use a battery charger to
start the engine (see “If the battery is flat”
in the chapter “In an emergency”).
WARMING THE ENGINE– Drive off slowly, at medium revs with-
out accelerating abruptly.
– Do not drive at full performance for the
initial kilometers of the journey, Wait until
the engine coolant temperature is between
50 and 60°C.SWITCHING OFF– Release the accelerator pedal and wait
until the engine reaches idle speed.
– Turn the ignition key to the STOPpo-
sition and switch off the engine.
WARNINGAfter a taxing drive it is bet-
ter to allow the engine to “catch its breath”
before turning it off by letting it idle to al-
low the temperature in the engine com-
partment to fall.
