check engine light FIAT 500C 2017 2.G User Guide

NOTE:If you crank or start the engine, you will have to
start this test over.
2. As soon as you cycle the ignition switch to the ON position, you will see the “Malfunction Indicator
Light (MIL)” symbol come on as part of a normal
bulb check.
3. Approximately 15 seconds later, one of two things will happen:
• The MIL will flash for about 10 seconds and then
return to being fully illuminated until you turn OFF
the ignition or start the engine. This means that your
vehicle’s OBD II system is not readyand you should
not proceed to the I/M station.
• The MIL will not flash at all and will remain fully
illuminated until you place the ignition in the off
position or start the engine. This means that your
vehicle’s OBD II system is readyand you can proceed
to the I/M station.
If your OBD II system is not ready,you should see your
authorized dealer or repair facility. If your vehicle was
recently serviced or had a battery failure or replace-
ment, you may need to do nothing more than drive
your vehicle as you normally would in order for your OBD II system to update. A recheck with the above test
routine may then indicate that the system is
now ready.
Regardless of whether your vehicle’s OBD II system is
ready or not, if the MIL is illuminated during normal
vehicle operation you should have your vehicle ser-
viced before going to the I/M station. The I/M station
can fail your vehicle because the MIL is on with the
engine running.
REPLACEMENT PARTS
Use of genuine parts for normal/scheduled mainte-
nance and repairs is highly recommended to ensure the
designed performance. Damage or failures 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.
DEALER SERVICE
Your authorized dealer has the qualified service person-
nel, special tools, and equipment to perform all service
operations in an expert manner. Service Manuals are
available which include detailed service information for
your vehicle. Refer to these Service Manuals before
attempting any procedure yourself.
282 MAINTAINING YOUR VEHICLE

•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 Schedule” 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. Riding the
brakes may also reduce 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.
300 MAINTAINING YOUR VEHICLE

MAINTENANCE SCHEDULE
Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change
indicator message will illuminate. This means that
service is required for your vehicle. Operating condi-
tions such as frequent short-trips, trailer tow, extremely
hot or cold ambient temperatures, and E85 fuel usage
will influence when the “Change Oil” or “Oil Change
Required” message is displayed. Severe Operating Con-
ditions can cause the change oil message to illuminate
as early as 3,500 miles (5,600 km) since last reset. Have
your vehicle serviced as soon as possible, within the
next 500 miles (805 km).
Your authorized dealer will reset the oil change indica-
tor message after completing the scheduled oil change.
If a scheduled oil change is performed by someone
other than your authorized dealer, the message can be
reset by referring to the steps described under “Instru-
ment Cluster Display” in “Understanding Your Instru-
ment Panel” for further information.NOTE:
Under no circumstances should oil change
intervals exceed 10,000 miles (16,000 km), twelve
months or 350 hours of engine run time, whichever
comes first. The 350 hours of engine run or idle time is
generally only a concern for fleet customers.
Severe Duty All Models
Change Engine Oil at 4,000 miles (6,500 km) if the
vehicle is operated in a dusty and off road environment
or is operated predominantly at idle or only very low
engine RPM’s. This type of vehicle use is considered
Severe Duty.
Once A Month Or Before A Long Trip:
Check engine oil level.
Check windshield washer fluid level.
Check the tire inflation pressures and look for unusual
wear or damage.
Check the fluid levels of the coolant reservoir and brake
master cylinder, and fill as needed.
Check function of all interior and exterior lights.
