engine overheat FIAT 500L 2016 2.G Owners Manual

1. Speedometer•Indicates vehicle speed
2. Fuel Gauge •The pointer shows the level of fuel in the fuel tank
when the ignition switch is in the ON/RUN position
3. Temperature Gauge •The temperature gauge shows engine coolant tem-
perature. Any reading within the normal range indi-
cates that the engine cooling system is operating
satisfactorily.
• The gauge pointer will likely indicate a higher tem-
perature when driving in hot weather or up moun-
tain grades. It should not be allowed to exceed the
upper limits of the normal operating range.CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge reads
“H” pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
drops back into the normal range. If the pointer
remains on the “H”, turn the engine off immediately
and call an authorized dealer for service.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer
for service if your vehicle overheats. If you decide to
look under the hood yourself, see “Maintaining Your
Vehicle”. Follow the warnings under the Cooling
System Pressure Cap paragraph.

The light also will turn on when the parking brake is
applied with the ignition switch in the ON/RUN posi-
tion.NOTE:
This light shows only that the parking brake is
applied. It does not show the degree of brake application.
Engine Temperature Warning Light
Red Warning Light What It Means
Engine Temperature Warning Light
This light warns of an overheated engine condition. As engine coolant temperatures rise and
the gauge approaches
H,this indicator will illuminate and a single chime will sound after
reaching a set threshold. Further overheating will cause the temperature gauge to pass H,a
continuous chime will occur until the engine is allowed to cool or the 4 minutes duration is
expired, whichever come first.
If the light turns on while driving, safely pull over and stop the vehicle. If the A/C system
is on, turn it off. Also, shift the transmission into NEUTRAL and idle the vehicle. If the tem-
perature reading does not return to normal, turn the engine off immediately and call for ser-
vice. Refer to “If Your Engine Overheats” in “What To Do In Emergencies” for further infor-
mation.

DRIVE position provides optimum driving characteris-
tics under all normal operating conditions.
When frequent transmission shifting occurs (such as
when operating the vehicle under heavy loading condi-
tions, in hilly terrain, or traveling into strong head
winds), use the AutoStick shift control (refer to AutoStick
in this section for further information) to select a lower
gear. Under these conditions, using a lower gear will
improve performance and extend transmission life by
reducing excessive shifting and heat buildup.
If the transmission temperature exceeds normal operat-
ing limits, the transmission controller will expand the
range of torque converter clutch engagement. This is
done to prevent transmission damage due to overheat-
ing.During cold temperatures, transmission operation may
be modified depending on engine coolant temperature.
Normal operation will resume once the engine tempera-
ture has risen to a suitable level.
Transmission Limp Home Mode
Transmission function is monitored electronically for
abnormal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission remains
in third gear regardless of which forward gear is selected.
PARK, REVERSE, and NEUTRAL will continue to oper-
ate. The Malfunction Indicator Light (MIL) may be illu-
minated. Limp Home Mode allows the vehicle to be
driven to an authorized dealer for service without dam-
aging the transmission.
In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing the
following steps:
288 STARTING AND OPERATING

NOTE:In AutoStick mode, the transmission will only
shift up or down when the driver moves the shift lever
rearward (+) or forward (-), except as described below.
• The transmission will automatically upshift when nec-
essary to prevent engine over-speed.
• The transmission will automatically downshift as the
vehicle slows (to prevent engine lugging) and will
display the current gear.
• The transmission will automatically downshift to first
gear when coming to a stop. After a stop, the driver
should manually upshift (+) the transmission as the
vehicle is accelerated.
• With six-speed automatic (Aisin AW6F25) transmis-
sion, you can start out (from a stop) in first, second, or
third gear. Starting out in second or third gear can be helpful in snow or icy conditions. To select second or
third gear after the vehicle is brought to a stop, tap the
shift lever rearward (+) once or twice.
• If a requested downshift would cause the engine to
over-speed, that shift will not occur.
• The system will ignore attempts to upshift at too low
of a vehicle speed.
• Avoid using speed control when AutoStick is engaged
because the transmission will not shift automatically.
• Transmission shifting will be more noticeable when
AutoStick is engaged.
• The system may revert to automatic shift mode if a
fault or overheat condition is detected.
To disengage AutoStick mode, return the shift lever to the
DRIVE position. You can shift in or out of the AutoStick

Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
•
The use of leaded gasoline is prohibited by Federal
law. Using leaded gasoline can impair engine perfor-
mance and damage the emissions control system.
• An out-of-tune engine or certain fuel or ignition
malfunctions can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune
or malfunctioning and may require immediate ser-
vice. Contact your authorized dealer for service
assistance.
• The use of fuel additives, which are now being
sold as octane enhancers, is not recommended.
(Continued)
CAUTION! (Continued)
Most of these products contain high concentrations
of methanol. Fuel system damage or vehicle perfor-
mance problems resulting from the use of such
fuels or additives is not the responsibility of the
manufacturer and may void or not be covered
under the New Vehicle Limited Warranty.
NOTE: Intentional tampering with the emissions control
system can result in civil penalties being assessed against
you.

HAZARD WARNING FLASHERS
The Hazard Warning flasher switch is located on the
instrument panel below the radio.Push the switch to turn on the Hazard Warning
flashers. When the switch is activated, all direc-
tional turn signals will flash on and off to warn oncoming
traffic of an emergency. Push the switch a second time to
turn off the Hazard Warning flashers.
Do not use this emergency warning system when the
vehicle is in motion. Use it when your vehicle is disabled
and it is creating a safety hazard for other motorists.
If it is necessary to leave the vehicle to go for service, the
Hazard Warning flashers will continue to operate with
the ignition key removed and the vehicle locked.
NOTE: With extended use, the Hazard Warning flashers
may wear down your battery.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate ac-
tion.
• On the highways — slow down.
• In city traffic — while stopped, place the transmission
in NEUTRAL, but do not increase engine idle speed.
NOTE: There are steps that you can take to slow down
an impending overheat condition:
• If your air conditioner (A/C) is on, turn it off. The A/C
system adds heat to the engine cooling system and
turning the A/C off can help remove this heat.
• You can also turn the temperature control to maximum
heat, the mode control to floor and the blower control
to high. This allows the heater core to act as a

FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand or snow, it
can often be moved using a rocking motion. Turn the
steering wheel right and left to clear the area around the
front wheels. Then shift back and forth between DRIVE
and REVERSE (with Automatic or Euro Twin Clutch
Transmission) or 2nd gear and REVERSE (with manual
transmission), while gently pressing the accelerator. Use
the least amount of accelerator pedal pressure that will
maintain the rocking motion, without spinning the
wheels, or racing the engine.
NOTE:For vehicles with Euro Twin Clutch transmission:
Shifts between DRIVE and REVERSE can only be
achieved at wheel speeds of approximately 6 mph
(10 km/h) or less.
CAUTION!
Racing the engine or spinning the wheels may lead to
transmission overheating and failure. Allow the en-
gine to idle with the transmission in NEUTRAL for at
least one minute after every five rocking-motion
cycles. This will minimize overheating and reduce
the risk of clutch or transmission failure during
prolonged efforts to free a stuck vehicle.
NOTE: Push the ESC Off switch, to place the Electronic
Stability Control (ESC) system in Partial Offmode,
before rocking the vehicle. Refer to “Electronic Brake
Control” in “Starting And Operating” for further infor-
mation. Once the vehicle has been freed, push the ESC
Off switch again to restore ESC Onmode.
370 WHAT TO DO IN EMERGENCIES

CAUTION!
•When “rocking” a stuck vehicle by shifting be-
tween DRIVE/2nd gear and REVERSE, do not spin
the wheels faster than 15 mph (24 km/h), or drive-
train damage may result.
• Revving the engine or spinning the wheels too fast
may lead to transmission overheating and failure.
It can also damage the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear (no trans-
mission shifting occurring).
WARNING!
Fast spinning tires can be dangerous. Forces gener-
ated by excessive wheel speeds may cause damage, or
even failure, of the axle and tires. A tire could

WARNING! (Continued)
explode and injure someone. Do not spin your vehi-
cle’s wheels faster than 30 mph (48 km/h) or for
longer than 30 seconds continuously without stop-
ping when you are stuck and do not let anyone near
a spinning wheel, no matter what the speed.
SHIFT LEVER OVERRIDE
If a malfunction occurs and the shift lever cannot be
moved out of the PARK position, you can use the
following procedure to temporarily move the shift lever:
1. Turn the engine OFF.
2. Firmly apply the parking brake.
3. Using a screwdriver or similar tool, carefully separate
the shift lever bezel and boot assembly from the center
console.6

WARNING!(Continued)
To Know Before Starting Your Vehicle” for further
information.
• A hot exhaust system can start a fire if you park
over materials that can burn. Such materials might
be grass or leaves coming into contact with your
exhaust system. Do not park or operate your ve-
hicle in areas where your exhaust system can con-
tact anything that can burn.
CAUTION!
• The catalytic converter requires the use of un-
leaded fuel only. Leaded gasoline will destroy the
effectiveness of the catalyst as an emissions control
device and may seriously reduce engine perfor-
mance and cause serious damage to the engine.
(Continued)
CAUTION! (Continued)
•Damage to the catalytic converter can result if your
vehicle is not kept in proper operating 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 damage to the converter and
vehicle.
Under normal operating conditions, the catalytic con-
verter will not require maintenance. However, it is im-
portant to keep the engine properly tuned to assure
proper catalyst operation and prevent possible catalyst
damage.
