2019 Alfa Romeo 4C Spider engine overheat

Instrument Cluster Descriptions
1. Temperature Gauge•The temperature gauge shows engine coolant tem-
perature. Any reading within the normal range
indicates that the engine cooling system is operat-
ing satisfactorily.
• The digital gauge will likely indicate a higher
temperature when driving in hot weather, or up
mountain grades. It should not be allowed to
exceed the upper limits of the normal operating
range.
NOTE: Driving with a hot engine cooling system could
damage your vehicle. The digital warning light may
switch on (together with a message on the display) to
indicate that the coolant temperature is too high; in this
case, stop the engine and contact a dedicated autho-
rized dealership.
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 “Servicing And
Maintenance.” Follow the warnings under the
Cooling System Pressure Cap paragraph.
2. Tachometer •This gauge measures engine revolutions per min-
ute (RPM x 1000). Before the pointer reaches the red
area, ease up on the accelerator to prevent engine
damage.
3. Speedometer •Indicates vehicle speed.
4. Fuel Gauge •The digital display shows the amount of fuel in the
tank.
• The switching on of the digital warning light
indicates that 1 – 1.3 gallons of fuel are left in the
tank; in this situation, refuel as soon as possible.
• Do not travel with the fuel tank almost empty; any
gaps in fuel delivery could damage the catalytic
converter.

— Air Bag Warning Light
This light will turn on for four to eight seconds as a bulb
check when the ignition is placed in the ON/RUN or
MAR/ON/RUN position. If the light is either not on
during startup, stays on, or turns on while driving, have
the system inspected at an authorized dealer as soon as
possible. This light will illuminate with a single chime
when a fault with the Air Bag Warning Light has been
detected, it will stay on until the fault is cleared. If the
light comes on intermittently or remains on while
driving, have an authorized dealer service the vehicle
immediately.
— Seat Belt Reminder Warning Light
When the ignition is first placed in the ON/RUN or
MAR/ON/RUN position, if the driver ’s seat belt is
unbuckled, a chime will sound and the light will turn
on. When driving, if the driver or front passenger seat
belt remains unbuckled, the Seat Belt Reminder Light
will flash or remain on continuously and a chime will
sound. Refer to “Occupant Restraint Systems” in
“Safety” for further information.
— Transmission Fault Warning Light
This light will illuminate (together with a message in
the instrument cluster display and a buzzer) to indicate
a transmission fault. Contact your authorized dealer if
the message remains after restarting the engine.
— Battery Charge Warning Light —
If Equipped
This light illuminates when the battery is not charging
properly. If it stays on while the engine is running, there
may be a malfunction with the charging system. Con-
tact your authorized dealer as soon as possible. This
indicates a possible problem with the electrical system
or a related component.
— Engine Coolant Temperature Warning Light
This warning light warns of an overheated engine
condition. If the engine coolant temperature is too high,
this indicator will illuminate and a single chime will
sound. If the temperature reaches the upper limit, a
continuous chime will sound for four minutes or until
the engine is able to cool: whichever comes 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 temperature reading does not return to
normal, turn the engine off immediately and call for
service.
Refer to “If Your Engine Overheats” in “In Case Of
Emergency” for further information.
Yellow Warning Lights
— Tire Pressure Monitoring System (TPMS)
Warning Light
The warning light switches on and a message is dis-
played to indicate that the tire pressure is lower than
the recommended value and/or that slow pressure loss
is occurring. In these cases, optimal tire duration and
fuel consumption may not be guaranteed.
Should one or more tires be in the condition mentioned
above, the display will show the indications corre-
sponding to each tire.
CAUTION!
Do not continue driving with one or more flat tires
as handling may be compromised. Stop the vehicle,
(Continued)
CAUTION! (Continued)
avoiding sharp braking and steering. If a tire punc-
ture occurs, repair immediately using the dedicated
tire repair kit and contact an authorized dealer as
soon as possible.
Each tire, including the spare (if provided), should be
checked monthly when cold and inflated to the inflation
pressure recommended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure label. (If
your vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation pres-
sure label, you should determine the proper tire infla-
tion pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale
when one or more of your tires is significantly under-
inflated. Accordingly, when the low tire pressure telltale
illuminates, you should stop and check your tires as
soon as possible, and inflate them to the proper pres-
sure. Driving on a significantly under-inflated tire
causes the tire to overheat and can lead to tire failure.

IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate
action.
•On highways — slow down.
• In city traffic — while stopped, place the transmis-
sion 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 maxi-
mum heat, the mode control to floor and the blower
control to high. This allows the heater core to act as a
supplement to the radiator and aids in removing heat
from the engine cooling system.
WARNING!
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 try to open a cooling system pressure
cap when the radiator or coolant bottle is hot.
CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the temperature gauge reads 240°F
(116°C) or greater pull over and stop the vehicle.
Idle the vehicle with the air conditioner turned off
until the coolant temperature drops back into the
normal range 200–230°F (93–110°C). The digital
warning light may switch on (together with a mes-
sage on the instrument cluster display) to indicate
that the coolant temperature is too high; in this case,
stop the engine and call for service.

CAUTION!(Continued)
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.

216 SERVICING AND MAINTENANCE

34°F (37°C) are anticipated. Please contact an
authorized dealer for assistance.
• Use only high purity water such as distilled or
deionized water when mixing the water/engine
coolant (antifreeze) solution. The use of lower quality
water will reduce the amount of corrosion protection
in the engine cooling system.
NOTE:
• It is the owner’s responsibility to maintain the proper
level of protection against freezing according to the
temperatures occurring in the area where the vehicle
is operated.
• Some vehicles require special tools to add coolant
properly. Failure to fill these systems properly could
lead to severe internal engine damage. If any coolant
is needed to be added to the system, please contact a
local authorized dealer.
• Mixing engine coolant (antifreeze) types is not rec-
ommended and can result in cooling system damage.
If HOAT and OAT coolant are mixed in an emer-
gency, have a authorized dealer drain, flush, and
refill with OAT coolant (conforming to MS.90032) as
soon as possible.Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of
engine coolant (antifreeze), and to ensure that engine
coolant (antifreeze) will return to the radiator from the
coolant expansion bottle/recovery tank if so equipped.
The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing sur-
faces.
WARNING!
• Do not open hot engine cooling system. Never
add engine coolant (antifreeze) when the engine
is overheated. Do not loosen or remove the cap to
cool an overheated engine. Heat causes pressure
to build up in the cooling system. To prevent
scalding or injury, do not remove the pressure cap
while the system is hot or under pressure.
• Do not use a pressure cap other than the one
specified for your vehicle. Personal injury or
engine damage may result.8
SERVICING AND MAINTENANCE 219

CNG And LP Fuel System Modifications
Modifications that allow the engine to run on Com-
pressed Natural Gas (CNG) or Liquid Propane (LP)
may result in damage to the engine, emissions, and fuel
system components. Problems that result from running
CNG or LP are not the responsibility of the manufac-
turer and may void or not be covered under the New
Vehicle Limited Warranty.
MMT In Gasoline
Methylcyclopentadienyl Manganese Tricarbonyl
(MMT) is a manganese-containing metallic additive
that is blended into some gasoline to increase octane.
Gasoline blended with MMT provides no performance
advantage beyond gasoline of the same octane number
without MMT. Gasoline blended with MMT reduces
spark plug life and reduces emissions system perfor-
mance in some vehicles. The manufacturer recom-
mends that gasoline without MMT be used in your
vehicle. The MMT content of gasoline may not be
indicated on the gasoline pump; therefore, you should
ask your gasoline retailer whether the gasoline contains
MMT. MMT is prohibited in Federal and California
reformulated gasoline.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
•The use of leaded gasoline is prohibited by Fed-
eral law. Using leaded gasoline can impair engine
performance 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
service. Contact an authorized dealer for service
assistance.
• The use of fuel additives, which are now being
sold as octane enhancers, is not recommended.
Most of these products contain high concentra-
tions of methanol. Fuel system damage or vehicle
performance 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.
