9. Malfunction Indicator Light
(MIL)The Malfunction Indicator
Light (MIL) is part of an on-
board diagnostic system,
called OBD, that monitors engine and
automatic transmission control sys-
tems. The light will illuminate when
the key is in the ON/RUN position,
before engine start. If the bulb does
not come on when turning the key
from OFF to ON/RUN, have the con-
dition checked promptly.
Certain conditions, such as poor fuel
quality, etc., may illuminate the MIL
after engine start. The vehicle should
be serviced if the light stays on
through several of your typical driv-
ing cycles. In most situations, the ve-
hicle will drive normally and will not
require towing.CAUTION!
Prolonged driving with the Mal-
function Indicator Light (MIL) on
could cause damage to the engine
control system. It also could affect
fuel economy and driveability. If
the MIL is flashing, severe catalytic
converter damage and power loss
will soon occur. Immediate service
is required.
WARNING!
A malfunctioning catalytic con-
verter, as referenced above, can
reach higher temperatures than in
normal operating conditions. This
can cause a fire if you drive slowly
or park over flammable substances
such as dry plants, wood, card-
board, etc. This could result in
death or serious injury to the driver,
occupants or others.
10. Speedometer
Indicates vehicle speed. 11. Fuel Door Reminder
The arrow in this symbol is
a reminder that the Fuel
Filler Door is located on the
left side of the vehicle.
12. Fuel Gauge
The pointer shows the level of fuel in
the fuel tank when the ignition switch
is in the ON/RUN position.
13. Air Bag Warning Light
This light will turn on for
four to eight seconds as a
bulb check when the igni-
tion switch is first turned to
ON/RUN. If the light is either not on
during starting, stays on, or turns on
while driving, have the system in-
spected at an authorized dealer as
soon as possible. Refer to “Occupant
Restraints” in “Things To Know Be-
fore Starting Your Vehicle” for further
information.

WARNING!(Continued)
Do not attempt to push or towyour vehicle to get it started. Ve-
hicles equipped with an auto-
matic transmission cannot be
started this way. Unburned fuel
could enter the catalytic con-
verter and once the engine has
started, ignite and damage the
converter and vehicle.
If the vehicle has a discharged battery, booster cables may be
used to obtain a start from a
booster battery or the battery in
another vehicle. This type of start
can be dangerous if done improp-
erly. Refer to “Jump Starting” in
“What To Do In Emergencies” for
further information.
Clearing A Flooded Engine (Using
ENGINE START/STOP Button)
If the engine fails to start after you
have followed the “Normal Starting”
or “Extreme Cold Weather" proce-
dures, it may be flooded. To clear any
excess fuel:
1. Press and hold the brake pedal. 2. Press the accelerator pedal all the
way to the floor and hold it.
3. Press and release the ENGINE
START/STOP button once.
The starter motor will engage auto-
matically, run for 10 seconds, and
then disengage. Once this occurs, re-
lease the accelerator pedal and the
brake pedal, wait 10 to 15 seconds,
then repeat the “Normal Starting”
procedure.
AFTER STARTING
The idle speed is controlled automati-
cally and it will decrease as the engine
warms up.
NORMAL STARTING –
DIESEL ENGINE
Observe the following when the en-
gine is operating.
All message center lights are off.
Malfunction Indicator Light (MIL)
is off.
Low Oil Pressure Light is off. Cold Weather Precautions
If the outside temperature is very low,
the diesel fuel thickens due to the
formation of parrafin clots and could
clog the diesel filter. In order to avoid
these problems, different types of die-
sel fuel are distributed according to
the season: summer type, winter type
and arctic type (cold, mountainous
areas).
If refuelling with diesel fuel whose
specifications are not suitable for the
outside temperature, it is advisable to
mix TUTELA DIESEL ART additive
in the proportions shown on the con-
tainer with the fuel. Pour the additive
into the tank before the fuel.
When using or parking the vehicle for
a long time in the mountains or cold
areas, it is advisable to refuel using
locally available diesel. In this case, it
is also advisable to keep the tank over
50% full.

ONBOARD DIAGNOSTIC
SYSTEM — OBD II
Your vehicle is equipped with a so-
phisticated onboard diagnostic sys-
tem called OBD II. This system moni-
tors the performance of the emissions,
engine, and automatic transmission
control systems. When these systems
are operating properly, your vehicle
will provide excellent performance
and fuel economy, as well as engine
emissions well within current govern-
ment regulations.
If any of these systems require service,
the OBD II system will turn on the
“Malfunction Indicator Light (MIL).”
It will also store diagnostic codes and
other information to assist your ser-
vice technician in making repairs. Al-
though your vehicle will usually be
drivable and not need towing, see
your authorized dealer for service as
soon as possible.
CAUTION!
Prolonged driving with the MILon could cause further damage to
the emissions control system. It
could also affect fuel economy
and driveability. The vehicle
must be serviced before any emis-
sions tests can be performed.
If the MIL is flashing while the engine is running, severe catalytic
converter damage and power loss
will soon occur. Immediate ser-
vice is required.
REPLACEMENT PARTS
Use of genuine parts for normal/
scheduled maintenance and repairs is
highly recommended to ensure the de-
signed performance. Damage or fail-
ures caused by the use of parts which
are not quality-equivalent to genuine
parts for maintenance and repairs will
not be covered by the manufacturer’s
warranty.
MAINTENANCE
PROCEDURES
The pages that follow contain the re-
quired maintenance services deter-
mined by the engineers who designed
your vehicle.
Besides those maintenance items
specified in the fixed maintenance
schedule, there are other components
which may require servicing or re-
placement in the future.
CAUTION!
Failure to properly maintain your vehicle or perform repairs and
service when necessary could re-
sult in more costly repairs, dam-
age to other components or nega-
tively impact vehicle
performance. Immediately have
potential malfunctions examined
by an authorized dealership or
qualified repair center.

tion.
CAUTION!
Car maintenance should be done at
a LANCIA Dealership. For routine
and minor maintenance operations
you wish to carry out yourself, we
do recommend you have the proper
equipment, genuine LANCIA spare
parts and the necessary fluids; do
not however carry out these opera-
tions if you have no experience.
INTERVENTION
REGENERATION
STRATEGY – 3.0L DIESEL
ENGINE
This vehicle is equipped with a state-
of-the-art engine and exhaust system
containing a diesel particulate filter.The engine and exhaust after-
treatment system work together to
meet the Emission standards. The
system manages engine combustion to
allow the exhaust system’s catalyst to
trap and burn Particulate Matter
(PM) pollutants with no input or in-
teraction on your part.
Refer to “Electronic Vehicle Informa-
tion Center (EVIC)” in “Understand-
ing Your Instrument Cluster” for fur-
ther information.
EXHAUST SYSTEM
The best protection against carbon
monoxide entry into the vehicle body
is a properly maintained engine ex-
haust system.
Whenever a change is noticed in the
sound of the exhaust system, when
exhaust fumes can be detected inside
the vehicle, or when the underside or
rear of the vehicle is damaged, have a
competent mechanic inspect the com-
plete exhaust system and adjacent
body areas for broken, damaged, de-
teriorated, or mispositioned parts.
Open seams or loose connections
could permit exhaust fumes to seepinto the passenger compartment. In
addition, have the exhaust system in-
spected each time the vehicle is raised
for lubrication or oil change. Replace
as required.
WARNING!
Exhaust gases can injure or kill.
They contain carbon monoxide
(CO), which is colorless and odor-
less. Breathing it can make you un-
conscious and can eventually poi-
son you. To avoid breathing CO,
refer to “Safety Tips/Exhaust Gas”
in “Things To Know Before Start-
ing Your Vehicle” for further infor-
mation.
CAUTION!
The catalytic converter requires the
use of unleaded fuel only. Leaded
gasoline will destroy the effective-
ness of the catalyst as an emissions
control device and may seriously
reduce engine performance and
cause serious damage to the engine.
278

Under normal operating conditions,
the catalytic converter will not require
maintenance. However, it is impor-
tant to keep the engine properly tuned
to assure proper catalyst operation
and prevent possible catalyst damage.
CAUTION!
Damage to the catalytic converter
can result if your vehicle is not kept
in proper operating condition. In
the event of engine malfunction,
particularly involving engine mis-
fire or other apparent loss of perfor-
mance, have your vehicle serviced
promptly. Continued operation of
your vehicle with a severe malfunc-
tion could cause the converter to
overheat, resulting in possible dam-
age to the converter and the vehicle.
NOTE: Intentional tampering
with emissions control systems can
result in civil penalties being as-
sessed against you.
WARNING!
A hot exhaust system can start a fire
if you park over materials that can
burn. Such materials might be
grass or leaves coming into contact
with your exhaust system. Do not
park or operate your vehicle in ar-
eas where your exhaust system can
contact anything that can burn.
In unusual situations involving
grossly malfunctioning engine opera-
tion, a scorching odor may indicate
severe and abnormal catalyst over-
heating. If this should occur, safely
bring the vehicle to a complete stop,
shut the engine OFF, and allow the
vehicle to cool. Thereafter, obtain ser-
vice, including a tune-up to manufac-
turer's specifications immediately.
To minimize the possibility of catalyst
damage:
Do not shut off the engine or inter- rupt the ignition when the trans-
mission is in gear and the vehicle is
in motion.
Do not try to start the engine by pushing or towing the vehicle. Do not idle the engine with any
spark plug wires disconnected or
removed, such as when diagnostic
testing, or for prolonged periods
during very rough idling or mal-
functioning operating conditions.
COOLING SYSTEM
WARNING!
When working near the radiatorcooling fan, disconnect the fan
motor lead or turn the ignition
switch to the LOCK position. The
fan is temperature controlled and
can start at anytime the ignition
switch is in the ON position.
You or others can be badly burned by hot engine coolant
(antifreeze) or steam from your
radiator. If you see or hear steam
coming from under the hood, do
not open the hood until the radia-
tor has had time to cool. Never try
to open a cooling system pressure
cap when the radiator is hot.
