A look at the Fiat 500 Instrument Panel

Fiat 500 Abarth Instrument Panel
The Fiat 500 instrument cluster contains all the vital information needed and sits directly in front of the driver and not scattered around the dashboard. Fiat 500 Abarth Instrument Panel shown.

The stylized instrument cluster on the Fiat 500 is a favorite feature among Fiat owners. The attractive panel houses the speedometer, tachometer, and an Electronic Vehicle Information Center (EVIC) that contains an engine temperature and fuel gauge. There is also an ambient light sensor that automatically adjust panel lighting for changing light conditions and the cluster has provisions for up to 31 warning indicators.

Engine Oil Pressure Low Message -
Each time the IPC receives a message from the PCM indicating the engine oil pressure is about 4 psi (27.5 kPa) or lower, the low oil pressure indicator will be illuminated.

The indicator remains illuminated until the IPC receives a message from the PCM indicating that the engine oil pressure is above about 4 psi (27.5 kPa), or until the ignition switch is turned to the OFF position, whichever occurs first. The IPC will only turn the indicator on in response to an engine oil pressure low message if the engine speed is greater than zero.

Engine Temperature High Message
Each time the IPC receives a message from the PCM indicating the engine coolant temperature is above about 248° F (120° C), the engine temperature indicator will be illuminated and a single chime tone is sounded.

The indicator remains illuminated until a message from the PCM indicating that the engine coolant temperature is below about 246° F (119° C) is received, or until the ignition switch is turned to the OFF position, whichever occurs first. The chime tone feature will only repeat during the same ignition cycle if the engine temperature indicator is cycled off and then on again by the appropriate engine temperature messages from the PCM.

In addition to the analog speedometer and tachometer, a digital bar graph engine temperature gauge and fuel level gauge are also provided.

Fiat 500 Temperature Gauge

Engine Temperature Gauge
This eight segment bar graph indicates the engine coolant temperature. When you turn on the ignition, the first segment of the gauge always illuminates, even if the temperature is -40 degrees Fahrenheit. The temperature is constantly monitored, and the Engine Coolant Temperature Indicator will illuminate when the upper segments on the bar graph are lit. Three fully illuminated temperature indicator bars equal 140° F (60° C)

Fiat 500 Fuel Gauge

Fuel Gauge
The fuel level in the Fiat 500's 10.5 gallon gas tank is displayed by a gauge broken up into a nine segment bar graph. The low fuel indicator (about the one-sixteenth graduation on the bar graph) and a single warning chime tone is sounded whenever the fuel gauge receives a signal indicating the tank is: about 10 percent full or less and the vehicle speed is zero, or about 10 percent full or less for 60 consecutive seconds and the vehicle speed is greater than zero.

The low fuel indicator will remain lit until one of the following conditions occurs first: the fuel gauge receives a message that the fuel tank is greater than 13 percent full for 10 consecutive seconds and the car's speed is zero, or for 60 consecutive seconds and the speed is greater than zero, or the ignition is finally turned off. The warning chime will repeat during the same running period only if the low fuel indicator is cycled OFF and then ON.

The fuel gauge receives its input from the Body Control Module (BCM) which monitors the signal from the fuel tank sending unit. The BCM applies an algorithm that tells the gauge what to display and also compensates for the effect of sloshing fuel in the gas tank.

Fiat 500 self leveling headlight icon
Cars with self leveling headlights have this icon that replaces the digital mph reading.

Fiat 500 EVIC layout
Fiat 500 models with automatic transmissions use the EVIC on the left. Manual transmission models use the EVIC on the right.

Electronic Vehicle Information Center (EVIC)
The Fiat 500's EVIC features a reconfigurable driver display and contains:
  1. Clock - An electronic digital clock within the EVIC electronic display can be configured for either a 24 hour display mode or a 12 hour display mode with AM and PM notations.
  2. Odometer - An electronic digital total odometer displays either kilometers (km) or miles (mi), depending upon the unit of measure required by the market for which the vehicle was originally manufactured for.
  3. Sport Mode Indicator - The word SPORT illuminates whenever the vehicle is being operated with the optional Sport mode.
  4. Electronic Message Display - The 14 character pseudo dot matrix display within the EVIC is used to display vehicle information to the driver. This includes audio system message displays, warnings and information from the trip computer.
  5. Digital Speedometer (5) - Except in vehicles equipped with headlamp leveling, the driver can choose to have an electronic digital speedometer display supplement the standard analog speedometer readings. Kilometers (km/h) or miles (MPH) may be chosen.
    Headlamp Leveling Indicator (5) - Depending on what market the vehicle is being sold, this indicator replaces the digital speedometer found in vehicles manufactured for markets where headlamp leveling is required.
  6. Ice Indicator - A snowflake icon is illuminated whenever the outside ambient temperature indicates that ice could be present on the roadway.
  7. Engine Coolant Temperature Gauge
  8. Shift Indicator - In vehicles equipped with a manual transmission (except Abarth) a shift indicator text and arrow are illuminated each time a transmission upshift is indicated by the Powertrain Control Module. Fiat 500 Abarth models have this light built into the turbo boost gauge.
  9. Fuel Gauge
  10. Outside Ambient Temperature Display - The outside ambient temperature displayed is driver selectable from Celsius (°C) or Fahrenheit (°F).
  11. Reserve Fuel Indicator - In vehicles manufactured for certain Latin American markets where an on-board fuel reserve feature is required, the fuel icon and the text GASOLINA will be illuminated whenever the vehicle is being operated on the reserve fuel supply.
  12. Gear Selector Indicator - In vehicles equipped with an optional automatic transmission, the gear selector indicator displays the transmission range currently selected.
Fiat 500 Lounge Instrument Panel
Depending on the model, the Fiat 500 instrument panel has different themes. This panel is from a Fiat 500 Lounge and features highly stylized gauge graphics.

Fiat 500 Sport Instrument Panel
The Fiat 500 Sport instrument cluster is clean, crisp and sporty .

One correction. In item 11, the indicator GASOLINE is used for a second fuel tank exclusively for gasoline (600ml), since in Brazil we have a model (Fiat 500 Cult) that can be fueled with gasoline or Ethanol (Flex). If the car is fueled solely with ethanol, the second tank is used for starting a cold (gasoline) and not used as a store, since the main reserve tank 4 liters

Wow! Great post Chris... this is great information!!
The Fiat 500 is an amazing car!

I believe that 6 isn't blank, but is indeed the ambient light sensor, which is of course the light sensor that is responsible for when your speedo cluster lights come on and off automatically. I am going to place a piece of black tape over it so to make the car think it's always night, as the 500 speedo is bloody hard to see most of the time.

Hi Chris,

Just changed speedo from miles to km so now I need to add my milage to my new speedo, any idea how to do that? said...

Hi Pederb,

I think that would need to be brought to a dealer and needs to be certified in some way. In the old days, the dealer would have to send it out to have it certified. There has to be some kind of controlled way of doing it or anyone could just change the mileage. Your dealer should know. Good luck and post on the forum to let us know how you made out.

Hi Chris,

Found out that you can use a MultiEcuScan to program pretty much anything including the mileage but you can only add milege not subtract.

The picture of the 500 sport instrument panel shows 3 horizontal dashes followed by a capital F, but does not explain them.

The digital speed indicator on my 2014 Fiat 500 POP is too small for a quick glance at the mph, while the semi-circle analog speedometer is hard to see while driving, especially at night. Is it possible to re-program the dash so that the time (which is larger) can be swapped for the mph ( which is smaller)?

Unknown said...

Guerry I totally agree with you on the MPH display. I don't care what day it is I want to know how fat I am going! If you found the answer please post it!

Unknown said...

Guerry Tanner I totally agree with you on the MPH display. I want to know how fast I am going not the date! During the day if I have polarized glasses I cannot see the red display at all!
Please post if this can be changed.

The 2015 Fiat Abarth has an electronic instrument combination. I would like to reprogram the software so that the tachometer shows a green band to redline then changes to red. That would be logical to me. The green band is already available in the thin film transistor LCD, so it should be doable. Any opinions on this?
