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.

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!
•

flammable and can explode, injuring you. Other
unapproved refrigerants or lubricants can cause
the system to fail, requiring costly repairs. Refer
to Warranty Information Book, for further war-
ranty information.
• The air conditioning system contains refrigerant
under high pressure. To avoid risk of personal
injury or damage to the system, adding refriger-
ant or any repair requiring lines to be discon-
nected should be done by an experienced techni-
cian.
CAUTION!
Do not use chemical flushes in your air condition-
ing system as the chemicals can damage your air
conditioning components. Such damage is not cov-
ered by the New Vehicle Limited Warranty.
Refrigerant Recovery And Recycling — R–1234yf
R–1234yf Air Conditioning Refrigerant is a hydrofluo-
roolefin (HFO) that is endorsed by the Environmental
Protection Agency and is an ozone-friendly substance with a low global-warming potential. The manufacturer
recommends that air conditioning service be performed
by an authorized dealer using recovery and recycling
equipment.
NOTE:
Use only manufacturer approved A/C system
PAG compressor oil, and refrigerants.
Body Lubrication
Locks and all body pivot points, including such items as
seat tracks, door hinge pivot points and rollers, liftgate,
tailgate, decklid, sliding doors and hood hinges, should
be lubricated periodically with a lithium based grease,
such as Mopar Spray White Lube to assure quiet, easy
operation and to protect against rust and wear. Prior to
the application of any lubricant, the parts concerned
should be wiped clean to remove dust and grit; after
lubricating excess oil and grease should be removed.
Particular attention should also be given to hood latch-
ing components to ensure proper function. When per-
forming other underhood services, the hood latch,
release mechanism and safety catch should be cleaned
and lubricated.
The external lock cylinders should be lubricated twice a
year, preferably in the Fall and Spring. Apply a small

condition. In the event of engine malfunction,
particularly involving engine misfire or other
apparent loss of performance, have your vehicle
serviced promptly. Continued operation of your
vehicle with a severe malfunction could cause the
converter to overheat, resulting in possible dam-
age to the converter and vehicle.
Under normal operating conditions, the catalytic con-
verter will not require maintenance. However, it is
important to keep the engine properly tuned to assure
proper catalyst operation and prevent possible catalyst
damage.
NOTE: Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe
and abnormal catalyst overheating. If this occurs, stop
the vehicle, turn off the engine and allow it to cool.
Service, including a tune-up to manufacturer’s specifi-
cations, should be obtained immediately.
To minimize the possibility of catalytic converter damage:
• Do not shut off the engine or interrupt the ignition,
when the transmission 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
idle or malfunctioning operating conditions.
Cooling System
WARNING!
• Turn vehicle off and disconnect the fan motor
lead before working near the radiator cooling fan.
•
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 radiator has had
time to cool. Never open a cooling system pressure
cap when the radiator or coolant bottle is hot.
(Continued)

SERVICING AND MAINTENANCE 207

•If frequent engine coolant (antifreeze) additions are
required, the cooling system should be pressure
tested for leaks.
• Maintain engine coolant (antifreeze) concentration at
a minimum of 50% OAT coolant (conforming to
MS.90032) and distilled water for proper corrosion
protection of your engine which contains aluminum
components.
• Make sure that the coolant expansion bottle overflow
hoses are not kinked or obstructed.
• Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean.
• Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs
may result in unsatisfactory engine coolant (anti-
freeze) performance, poor gas mileage, and increased
emissions.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically. Refer to the “Maintenance Plan” in this section for the
proper maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure and
possibly a collision. Driving with your foot resting
or riding on the brake pedal can result in abnor-
mally high brake temperatures, excessive lining
wear, and possible brake damage. You would not
have your full braking capacity in an emergency.
Brake Master Cylinder
The fluid level in the master cylinder should be checked
when performing under hood services, or immediately
if the “Brake Warning Light” is on.
Be sure to clean the top of the master cylinder area
before removing the cap. If necessary, add fluid to bring
the fluid level up to the requirements described on the
brake fluid reservoir. Fluid level can be expected to fall
as the brake pads wear. The brake fluid level should be
checked when the pads are replaced. However, low
fluid level may be caused by a leak and a checkup may
be needed.
212 SERVICING AND MAINTENANCE

Adding Brake Fluid
If the fluid level in the reservoir is not sufficient,
proceed as follows:
1. Take the black funnel for topping up the brake fluidand its extension pipe from the service kit in the
luggage compartment.
2. Loosen the reservoir plug and introduce the funnel with the extension pipe in the reservoir inlet.
3. After topping up, remove the funnel with the exten- sion pipe.
4. Tighten the reservoir plug. 5. Reposition the brake fluid protection panel and
tighten the two screws.
NOTE: Be very careful while removing the plug from
the opening to prevent the plug from falling inside the
vehicle body.
Alfa Twin Clutch Transmission
Selection Of Lubricant
It is important to use the proper transmission fluid to
ensure optimum transmission performance and life. Use
only the manufacturer ’s specified transmission fluid.
Refer to “Fluids And Lubricants” in “Technical Specifica-
tions” for fluid specifications. It is important to maintain
the transmission fluid at the correct level using the
recommended fluid. No chemical flushes should be used
in any transmission; only the approved lubricant should
be used.
CAUTION!
Using a transmission fluid other than the manufac-
turer ’s recommended fluid may cause deterioration
in transmission shift quality. Refer to “Fluids And
Lubricants” in “Technical Specifications” for fluid
specifications.

Special Additives
The manufacturer strongly recommends against using
any special additives in the transmission.
Transmission fluid is an engineered product and its
performance may be impaired by supplemental addi-
tives. Therefore, do not add any fluid additives to the
transmission. The only exception to this policy is the
use of special dyes for diagnosing fluid leaks.
CAUTION!
Do not use chemical flushes in your transmission as
the chemicals can damage your transmission com-
ponents. Such damage is not covered by the New
Vehicle Limited Warranty.
Fluid Level Check
The fluid level is preset at the factory and does not
require adjustment under normal operating conditions.
Frequent fluid level checks are not required, but have
your authorized dealer check the fluid level as specified
in the Maintenance Schedule to ensure proper transmis-
sion function and longevity. The transmission has no
dipstick, but your authorized dealer can check your
transmission fluid level using special service tools. Ifyou notice fluid leakage or transmission malfunction,
visit your authorized dealer immediately to have the
transmission fluid level checked. Operating the vehicle
with an improper fluid level can cause severe transmis-
sion damage.
Fluid Changes
Under normal operating conditions, the fluid installed
at the factory will provide satisfactory lubrication for
the life of the vehicle. However, change the fluid if it
becomes contaminated (with water, etc.), or if the
transmission is disassembled for any reason.
RAISING THE VEHICLE
In the case where it is necessary to raise the vehicle, go
to an authorized dealer or service station.
