* The spark plug change interval is mileage based only,
yearly intervals do not apply. The following are essen-
tial to ensure correct operation and prevent serious
damage to the engine:
•Only use spark plugs of the same make and type
which are specially certified for such engines (refer to
“Fluids And Lubricants” in “Technical Specifica-
tions” for further information).
• Strictly comply with the spark plug replacement
interval given in the maintenance plan for spark plug
replacement.
• Contact your Alfa Romeo Dealer if you have ques-
tions.
** Regardless of the distance covered, the timing belt
must be changed every four years for particularly
demanding use (cold climates, city driving, long peri-
ods of idling) or at least every five years.
*** The actual interval for changing the oil and replac-
ing the engine oil filter depends on the vehicle usage
conditions and is signalled by the warning light or
message (if present) on the instrument panel or every 12
months. **** If the vehicle is operated in a dusty or dirty
environment the engine air filter has to be changed
every 6,500 miles (10,000 km).
***** DOT 4 brake fluid must be changed every two
years regardless of mileage.
WARNING!
•
You can be badly injured working on or around a
motor vehicle. Do only service work for which
you have the knowledge and the right equipment.
If you have any doubt about your ability to
perform a service job, take your vehicle to a
competent mechanic.
• Failure to properly inspect and maintain your
vehicle could result in a component malfunction
and effect vehicle handling and performance.
This could cause an accident.

Checking Oil Level
To assure proper engine lubrication, the engine oil must
be maintained at the correct level. Check the oil level at
regular intervals. The best time to check the engine oil
level is before starting the engine after it has sat
overnight.
Do not check oil level when the engine is warm.
Checking engine oil level when the engine is warm will
give you an incorrect reading.
Checking the oil while the vehicle is on level ground, and
has sat overnight, will improve the accuracy of the oil
level readings. Maintain the oil level between the range
markings on the dipstick. The safe range is indicated by a
crosshatch zone. Adding 1 quart of oil when the reading
is at the low end of the indicated range will result in the
oil level at the full end of the indicator range.
CAUTION!
Do not overfill the engine with oil. Overfilling the
engine with oil will cause oil aeration, which can
lead to loss of oil pressure and an increase in oil
temperature. This loss of oil pressure and increased
oil temperature could damage your engine.
Adding Washer Solvent
To check the windshield washer solvent level, proceed
as follows:
1. To avoid any interference during the procedure, liftthe windshield wiper blade.

2 — Washer Solvent Access Panel

DEALER SERVICE
The pages that follow contain therequiredmaintenance
services determined 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 replacement in the
future.
CAUTION!
• Failure to properly maintain your vehicle or per-
form repairs and service when necessary could
result in more costly repairs, damage to other
components or negatively impact vehicle perfor-
mance. Immediately have potential malfunctions
examined by an authorized dealer or qualified
repair center.
• Your vehicle has been built with improved fluids
that protect the performance and durability of
your vehicle and also allow extended mainte-
nance intervals. Do not use chemical flushes in
these components as the chemicals can damage

CAUTION! (Continued)
your engine, transmission, or air conditioning.
Such damage is not covered by the New Vehicle
Limited Warranty. If a flush is needed because of
component malfunction, use only the specified
fluid for the flushing procedure.
Engine Oil
Change Engine Oil
The oil change indicator system will remind you that it
is time to take your vehicle in for scheduled mainte-
nance. Refer to the “Maintenance Plan” for further
information.
NOTE:The actual interval for changing the oil and
replacing the engine oil filter depends on the vehicle
usage conditions and is signalled by the warning light
or message (if present) on the instrument panel or every
12 months.
Engine Oil Selection
For best performance and maximum protection for
turbocharged engines under all types of operating
conditions, the manufacturer recommends synthetic
200 SERVICING AND MAINTENANCE

engine oils that are API Certified and meet the require-
ments of FCA Material Standard MS-12991.
Engine Oil Viscosity — 1750 Turbo Engine (SAE
Grade)
SAE 5W-40 full synthetic engine oil is recommended for
all operating temperatures. This engine oil improves
low temperature starting and vehicle fuel economy.
Lubricants which do not have both the engine oil
certification mark and the correct SAE viscosity grade
number should not be used.
Materials Added To Engine Oil
The manufacturer strongly recommends against the
addition of any additives (other than leak detection
dyes) to the engine oil. Engine oil is an engineered
product and its performance may be impaired by
supplemental additives.
Disposing Of Used Engine Oil And Oil Filters
Care should be taken in disposing of used engine oil
and oil filters from your vehicle. Used oil and oil filters,
indiscriminately discarded, can present a problem to
the environment. Contact an authorized dealer, servicestation or governmental agency for advice on how and
where used oil and oil filters can be safely discarded in
your area.
Engine Oil Filter
The engine oil filter should be replaced with a new filter
at every engine oil change.
Engine Oil Filter Selection
This manufacturer’s engines have a full-flow type dis-
posable oil filter. Use a filter of this type for replace-
ment. The quality of replacement filters varies consid-
erably. Only high quality filters should be used to
assure most efficient service. Mopar engine oil filters are
high quality oil filters and are recommended.
Engine Air Cleaner Filter
Refer to the “Maintenance Plan” in this section for the
proper maintenance intervals.
NOTE:
Be sure to follow the “Severe Duty Conditions”
maintenance interval if applicable.

WARNING!
The air induction system (air cleaner, hoses, etc.)
can provide a measure of protection in the case of
engine backfire. Do not remove the air induction
system (air cleaner, hoses, etc.) unless such removal
is necessary for repair or maintenance. Make sure
that no one is near the engine compartment before
starting the vehicle with the air induction system
(air cleaner, hoses, etc.) removed. Failure to do so
can result in serious personal injury.
Engine Air Cleaner Filter Selection
The quality of replacement engine air cleaner filters
varies considerably. Only high quality filters should be
used to assure most efficient service. Mopar engine air
cleaner filters are a high quality filter and are recom-
mended.
Engine Cover
To avoid possible damage to the engine cover, please
disconnect each of the four mounting studs by pulling
the engine cover upward, and then lift off the complete cover. Tilting the engine cover when one or more studs
are still engaged will lead to premature failure of the
couplers.
To reassemble the cover back onto the engine, first make
sure it is properly aligned, the oil cap is centered, and
that all four studs are lined up with their couplers. Then
gently push on the four corners of the engine cover to
snap the stud back into position.
No tools are required to remove or reassemble the
engine cover.
Air Conditioner Maintenance
For best possible performance, your air conditioner
should be checked and serviced by an authorized dealer
at the start of each warm season. This service should
include cleaning of the condenser fins and a perfor-
mance test. Drive belt tension should also be checked at
this time.
WARNING!
•
Use only refrigerants and compressor lubricants
approved by the manufacturer for your air condi-
tioning system. Some unapproved refrigerants are
