warning light FIAT 500C 2018 Service Manual

POWER STEERING
The electric power steering system will give you good
vehicle response and increased ease of maneuverability in
tight spaces. The system will vary its assist to provide light
efforts while parking and good feel while driving. If the
electric steering system experiences a fault that prevents it
from providing assist, you will still have the ability to steer
the vehicle manually.
WARNING!Continued operation with reduced or no power steer-
ing assist could pose a safety risk to yourself and
others. Service should be obtained as soon as possible.
If the Steering icon is flashing, it indicates that the vehicle
needs to be taken to an authorized dealer for service. It is
likely the vehicle has lost power steering assistance.
If the Steering icon is displayed and the “SERVICE POWER
STEERING” message is displayed on the instrument clus-
ter screen, they indicate that extreme steering maneuvers
may have occurred which caused an over temperature condition in the power steering system. Once driving
conditions are safe, pull over and let the vehicle idle for a
few moments until the icon and message turn off. Refer to
“Instrument Cluster Display” in “Getting To Know Your
Instrument Panel” for further information.
If the Steering icon, and the  SERVICE POWER STEERING
- ASSIST OFF  messages are displayed on the instrument
cluster screen, the vehicle needs to be taken to an autho-
rized dealer for service. Refer to “Instrument Cluster
Display” in “Getting To Know Your Instrument Panel” for
further information.
NOTE:
• Even if the power steering assistance is no longer
operational, it is still possible to steer the vehicle. Under
these conditions there will be a substantial increase in
steering effort, especially at low speeds and during
parking maneuvers.
• If the condition persists, see an authorized dealer for
service. 6STARTING AND OPERATING 177

SPEED CONTROL
When engaged, the Speed Control takes over accelerator
operations at speeds greater than 25 mph (40 km/h).
The Speed Control buttons are located on the right side of
the steering wheel. NOTE: In order to ensure proper operation, the Speed
Control system has been designed to shut down if multiple
Speed Control functions are operated at the same time. If
this occurs, the Speed Control system can be reactivated by
pushing the Speed Control ON/OFF button and resetting
the desired vehicle set speed.
To Activate
Push the ON/OFF button. The Cruise Indicator Light in
the instrument cluster display will illuminate. To turn the
system off, push the ON/OFF button a second time. The
Cruise Indicator Light will turn off. The system should be
turned off when not in use.
WARNING!Leaving the Speed Control system on when not in use
is dangerous. You could accidentally set the system or
cause it to go faster than you want. You could lose
control and have an accident. Always leave the system
off when you are not using it.Speed Control Buttons1 — ON/OFF 3 — SET (-)/Decel
2 — RES (+)/Resume/Accel 4 — CANC/Cancel178 STARTING AND OPERATING

• If the button is continually pushed, the set speed will
continue to decrease until the button is released, then the
new set speed will be established.
Metric Speed (km/h)
• Pushing the SET (-) button once will result in a 1 km/h
decrease in set speed. Each subsequent tap of the button
results in a decrease of 1 km/h.
• If the button is continually pushed, the set speed will
continue to decrease until the button is released, then the
new set speed will be established.
To Accelerate For Passing
Press the accelerator as you would normally. When the
pedal is released, the vehicle will return to the set speed.
Using Speed Control On Hills
The transmission may downshift on hills to maintain the
vehicle set speed.
NOTE: The Speed Control system maintains speed up and
down hills. A slight speed change on moderate hills is
normal. On steep hills, a greater speed loss or gain may occur so it
may be preferable to drive without Speed Control.
WARNING!Speed Control can be dangerous where the system
cannot maintain a constant speed. Your vehicle could
go too fast for the conditions, and you could lose
control and have an accident. Do not use Speed Control
in heavy traffic or on roads that are winding, icy,
snow-covered or slippery.
To Resume Speed
To resume a previously set speed, push the RES (+) button
and release. Resume can be used at any speed above
25 mph (40 km/h).
To Deactivate
A soft tap on the brake pedal, pushing the CANC button,
or normal brake pressure while slowing the vehicle will
deactivate the Speed Control without erasing the set speed
from memory.
Pushing the ON/OFF button or turning the ignition switch
OFF erases the set speed from memory.180 STARTING AND OPERATING

WARNING!• Never have any smoking materials lit in or near the
vehicle when the gas cap is removed or the tank is
being filled.
• Never add fuel when the engine is running. It may
cause the MIL to turn on and could cause a fire.
• A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle. You
could be burned. Always place gas containers on the
ground while filling.
CAUTION!• Damage to the fuel system or emission control sys-
tem could result from using an improper fuel filler
cap. A poorly fitting cap could let impurities into the
fuel system. Also, a poorly fitting aftermarket cap
can cause the “Malfunction Indicator Light (MIL)”
to illuminate, due to fuel vapors escaping from the
system.
• To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling. NOTE:
• When the fuel nozzle “clicks” or shuts off, the fuel tank
is full.
• Tighten the gas cap about 1/4 turn until you hear one
click. This is an indication that the cap is properly
tightened.
• If the gas cap is not tightened properly, the MIL will
come on. Be sure the gas cap is tightened every time the
vehicle is refueled.
Loose Fuel Filler Cap Message
After fuel has been added, the vehicle diagnostic system
can determine if the fuel filler cap is possibly loose,
improperly installed, or damaged. If the system detects a
malfunction, the “gASCAP” message will display in the
odometer display. Tighten the gas cap until a  clicking 
sound is heard. This is an indication that the gas cap is
properly tightened. Push the odometer reset button to turn
the message off. If the problem persists, the message will
appear the next time the vehicle is started. This might
indicate a damaged cap. If the problem is detected twice in
a row, the system will turn on the MIL. Resolving the
problem will turn the MIL off. 6STARTING AND OPERATING 187

Flowing/Rising Water
WARNING!Do not drive on or across a road or path where water is
flowing and/or rising (as in storm run-off). Flowing
water can wear away the road or path’s surface and
cause your vehicle to sink into deeper water. Further-
more, flowing and/or rising water can carry your ve-
hicle away swiftly. Failure to follow this warning may
result in injuries that are serious or fatal to you, your
passengers, and others around you.
Shallow Standing Water
Although your vehicle is capable of driving through shal-
low standing water, consider the following Cautions and
Warnings before doing so.
WARNING!• Driving through standing water limits your vehicle’s
traction capabilities. Do not exceed 5 mph (8 km/h)
when driving through standing water. (Continued) WARNING! (Continued)• Driving through standing water limits your vehicle’s
braking capabilities, which increases stopping dis-
tances. Therefore, after driving through standing
water, drive slowly and lightly press on the brake
pedal several times to dry the brakes.
• Failure to follow these warnings may result in inju-
ries that are serious or fatal to you, your passengers,
and others around you.
CAUTION!• Always check the depth of the standing water before
driving through it. Never drive through standing
water that is deeper than the bottom of the tire rims
mounted on the vehicle.
• Determine the condition of the road or the path that
is under water and if there are any obstacles in the
way before driving through the standing water.
• Do not exceed 5 mph (8 km/h) when driving through
standing water. This will minimize wave effects. (Continued)192 STARTING AND OPERATING

Replacing Interior Bulbs
Rear Cargo Lamp
1. Using a suitable tool open the light box.
2. Pull the bulb out.
3. Replace the bulb, and reinstall the light box cover.
FUSES
WARNING!• When replacing a blown fuse, always use an appro-
priate replacement fuse with the same amp rating as
the original fuse. Never replace a fuse with another
fuse of higher amp rating. Never replace a blown
fuse with metal wires or any other material. Do not
place a fuse inside a circuit breaker cavity or vice
versa. Failure to use proper fuses may result in
serious personal injury, fire and/or property damage.
• Before replacing a fuse, make sure that the ignition is
off and that all the other services are switched off
and/or disengaged.
• If the replaced fuse blows again, contact an autho-
rized dealer. (Continued) WARNING! (Continued)• If a general protection fuse for safety systems (air
bag system, braking system), power unit systems
(engine system, transmission system) or steering
system blows, contact an authorized dealer.
Interior Fuses
The interior fuse panel is part of the Body Control Module
(BCM) and is located on the driver’s side under the
instrument panel.

the button. An audible click will be heard indicating the
bottle is locked into place. Release the button.
6. Verify that the cap is installed on the fitting at the end of
the Sealant Hose (3) and return the hose to its storage
area (located on top of the housing).
7. Return the Tire Service Kit to its storage location in the
vehicle.
JUMP STARTING PROCEDURE
If your vehicle has a discharged battery, it can be jump-
started using a set of jumper cables and a battery in another
vehicle or by using a portable battery booster pack. Jump
starting can be dangerous if done improperly so please
follow the procedures in this section carefully.
NOTE: When using a portable battery booster pack, follow
the manufacturer ’s operating instructions and precautions.
WARNING!Do not attempt jump starting if the battery is frozen. It
could rupture or explode and cause personal injury. CAUTION!Do not use a portable battery booster pack or any other
booster source with a system voltage greater than 12
Volts or damage to the battery, starter motor, alternator
or electrical system may occur.
Preparations For Jump Start
The battery in your vehicle is located between the left front
headlight assembly and the left front wheel splash shield.

Brake Master Cylinder
The fluid in the master cylinder should be checked when
performing under hood services or immediately if the
“Brake Warning Light” is illuminated.
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. With disc brakes, fluid level can be expected to
fall as the brake pads wear. Brake fluid level should be
checked when pads are replaced. However, low fluid level
may be caused by a leak and a checkup may be needed.
Use only manufacturer’s recommended brake fluid. Refer
to “Fluids And Lubricants” in “Technical Specifications”
for further information.
WARNING!• Use only manufacturer’s recommended brake fluid.
Refer to “Fluids And Lubricants” in “Technical
Specifications” for further information. Using the
wrong type of brake fluid can severely damage your
brake system and/or impair its performance. The (Continued) WARNING! (Continued)proper type of brake fluid for your vehicle is also
identified on the original factory installed hydraulic
master cylinder reservoir.
• To avoid contamination from foreign matter or mois-
ture, use only new brake fluid or fluid that has been
in a tightly closed container. Keep the master cylin-
der reservoir cap secured at all times. Brake fluid in
a open container absorbs moisture from the air
resulting in a lower boiling point. This may cause it
to boil unexpectedly during hard or prolonged brak-
ing, resulting in sudden brake failure. This could
result in a collision.
• Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing the
brake fluid to catch fire. Brake fluid can also damage
painted and vinyl surfaces, care should be taken to
avoid its contact with these surfaces.
• Do not allow petroleum based fluid to contaminate
the brake fluid. Brake seal components could be
damaged, causing partial or complete brake failure.
This could result in a collision. 8SERVICING AND MAINTENANCE 253

NOTE: Wheel Valve Stem must be replaced as well when
installing new tires due to wear and tear in existing tires.
Keep dismounted tires in a cool, dry place with as little
exposure to light as possible. Protect tires from contact with
oil, grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for
wear and correct cold tire inflation pressures. The manu-
facturer strongly recommends that you use tires equivalent
to the originals in size, quality and performance when
replacement is needed. Refer to the paragraph on “Tread
Wear Indicators” in this section. Refer to the Tire and
Loading Information placard or the Vehicle Certification
Label for the size designation of your tire. The Load Index
and Speed Symbol for your tire will be found on the
original equipment tire sidewall.
See the Tire Sizing Chart example found in the “Tire Safety
Information” section of this manual for more information
relating to the Load Index and Speed Symbol of a tire. It is recommended to replace the two front tires or two rear
tires as a pair. Replacing just one tire can seriously affect
your vehicle’s handling. If you ever replace a wheel, make
sure that the wheel’s specifications match those of the
original wheels.
It is recommended you contact an authorized tire dealer or
original equipment dealer with any questions you may
have on tire specifications or capability. Failure to use
equivalent replacement tires may adversely affect the
safety, handling, and ride of your vehicle.
WARNING!• Do not use a tire, wheel size, load rating, or speed
rating other than that specified for your vehicle.
Some combinations of unapproved tires and wheels
may change suspension dimensions and perfor-
mance characteristics, resulting in changes to steer-
ing, handling, and braking of your vehicle. This can
cause unpredictable handling and stress to steering
and suspension components. You could lose control
and have a collision resulting in serious injury or
death. Use only the tire and wheel sizes with load
ratings approved for your vehicle. (Continued)268 SERVICING AND MAINTENANCE

BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic brake sys-
tems. If either of the two hydraulic systems loses normal
capability, the remaining system will still function. How-
ever, there will be some loss of overall braking effective-
ness. You may notice increased pedal travel during appli-
cation, greater pedal force required to slow or stop, and
potential activation of the Brake Warning Light.
In the event power assist is lost for any reason (i.e.,
repeated brake applications with the engine OFF) the
brakes will still function. However, the effort required to
brake the vehicle will be much greater than that required
with the power system operating. WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure that
the wheel is properly mounted to the vehicle. Any time a
wheel has been removed and reinstalled on the vehicle, the
lug nuts/bolts should be torqued using a properly cali-
brated torque wrench using a high quality six sided (hex)
deep wall socket.
