Engine oil level check (JTD versions only)
Indication is correct only if oil level has been checked with the car on a level surface.
If oil level is low, before topping up, check it by the proper dipstick as described in paragraph “Checking fluid levels”
in the “Car maintenance” chapter.

rear side bags are deactivated by the
relevant key switch.EOBD ENGINE
CONTROL SYSTEM
FAILURE
In normal conditions, turning the
ignition key to MAR, the warning
light turns on, but it should go off
when the engine has started.
If the warning light stays on or
turns on when travelling together
with message “ENGINE CONTROL
SYSTEM FAULT” on the multi-
function display:
Glowing steadily- means a fault
in the supply/ignition system which
could cause high emissions at the
exhaust, possible lack of perfor-
mance, poor handling and high con-
sumption levels.
In these conditions it is possible to
continue driving without however
demanding heavy effort or high
speeds. Prolonged use of the car with
the warning light on may cause
damages. Contact a Lancia
Dealershipas soon as possible.
The warning light goes off if the
fault disappears but it is however
stored by the system. FRONT PASSENGER
AIRBAG DEACTIVATED
The warning light comes
on when front passenger airbag is
deactivated by the relevant key
switch.

If the ¬warning light
does not turn on when
turning the ignition key to
MAR or if it stays on when travel-
ling, (together with message on
display) this could indicate a fail-
ure in safety retaining systems; un-
der this condition air bags or pre-
tensioners could not trigger in the
event of collision or, in a restricted
number of cases, they could trig-
ger accidentally. Stop the car and
contact Lancia Dealership to have
the system checked immediately.

Outside temperature is low
and there could be ice on the roadRemarks
Under certain conditions
(bridges, overbridges,
curves or road sections in
the shade, etc.) the air temperature
at ground level can be lower than
that at sensor level and therefore
there can be ice on the road

AIR VENTS
The car is fitted with three air
vents set on the dashboard: two
vents A(fig. 118) on driver side and
one B (fig. 119) on passenger side,
sending air in the passenger com-
partment in a “diffused” mode.
This particular function conveys air
at low speed, about half of the usual
flow, through additional vents.
Moreover, it reduces the air impact
on the passengers and the noise due
to the air coming out of the vents,
thus improving the passengers' com-
fort.IMPORTANTWhen the outside
temperature is very high (over 30°C),
to reach the selected temperature as
soon as possible, it is suggested to op-
erate air vents only after the system
has reached steady working condi-
tions.
IMPORTANTOn versions equipped
with solar cell operated sunroof
(where provided), to check operation
at first speed of climate control sys-
tem fan when the car is parked, dis-
engage air vents and set air distribu-
tion from central dashboard vents
only before leaving the car.

Air vents (open) are actually used
only when the control for directing
air flow on the instrument panel is
operated.
Air vents are opened by rotating
the dashboard central vent knobs
beyond the upper stop limit (fig.
120):
– control Afor air vents on driver
side
– control Bfor air vent on passen-
ger side.
At the stop limit of these controls
there is a button which, if pressed,
sends a signal to the climate system
control unit.

146
AUTOMATIC
CLIMATE
CONTROL SYSTEM
GENERAL
The car can be equipped with a
two-zone or multi-zone automatic
climate control system.
The two-zone climate control sys-
tem controls temperature, air distri-
bution and flow inside the passenger
compartment in two areas: driver
side and passenger side.
The multi-zone climate control sys-
tem controls temperature, air distrib-
ution and flow inside the passenger
compartment in three areas: driver
side, passenger side or back-seat pas-
sengers.
Control of front-seat passenger and
back-seat passengers is alternated;
when the button led REARis turned
off, the front-seat passenger control
is operating, whereas when button
REARis pressed (button led turned
on), the back control panel is acti-
vated, thus excluding those for the
front-seat passenger.Temperature check is based on the
“heat balance” concept, which
means that the system works con-
stantly to keep a regular balance
between incoming and outgoing heat
energy, in order to stabilize temper-
ature inside the passenger compart-
ment and compensate possible vari-
ations of outside climate, sun radi-
ance included. For optimal control
of temperature in the two areas of
the passenger compartment, the sys-
tem is equipped with a sun ray sen-
sor.
The system features a pollution
sensor which can automatically
switch the air recirculation function
on to reduce the unpleasant effects
of polluted air in cities, queues, tun-
nels and when the windscreen wash-
er is operated (with the characteris-
tic smell of alcohol).
The air quality is controlled by an
active carbon dust/pollen filter
which has the double function of
mechanically filtering the particles
dispersed in the air and attenuating
the peak accumulation of certain
pollutants.Parameters and functions auto-
matically controlled are the follow-
ing:
– temperature of air let into dri-
ver/passenger vents (front-seat/
back-seats);
– air distribution to vents on dri-
ver/passenger side (front-seat/
back-seats);
– fan speed (continuos variation of
air flow);
– compressor activation (to cool
air);
– air recirculation.
All these functions can be adjusted
manually, it means that one or more
system functions can be selected and
that it is possible to change their
parameters. However, in this way
the system is unable to control man-
ually selected functions which will
be changed by the system only for
safety reasons, while keeping the
required temperature.
