2018 Alfa Romeo 4C coolant temperature

INSTRUMENT CLUSTER
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.

54 GETTING TO KNOW YOUR INSTRUMENT PANEL

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.
•
The fuel pump symbol points to the side of
the vehicle where the fuel door is located.
5. “Alfa DNA” Driving Mode Indicator
•This area of the cluster displays which driving
mode the vehicle is currently in. A letter (d, n, or a)
corresponding to the active driving mode (dynamic
or race, natural, all weather) and a dedicated mes-
sage is shown on the display.
NOTE: The hard telltales will illuminate for a bulb
check when the ignition is first cycled.

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 light warns of an overheated engine condition. If
the engine coolant temperature is too high, this indica-
tor will illuminate and a single chime will sound. If the
temperature reaches the upper limit, a continuous
chime will be 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 in sequence.
CAUTION!
Do not continue driving with one or more flat tires
as handling may be compromised. Stop the vehicle,
avoiding sharp braking and steering. If a tire punc-
ture occurs, repair immediately using the dedicated
tire repair kit and contact your 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.)

to start within 10 seconds, turn the ignition switch to
the STOP (OFF/LOCK) position, wait 10 to 15 seconds,
then repeat the “Normal Starting” procedure.
Cold Weather Operation
Your engine is designed to operate at temperatures as
low as 0°F (-18°C).
CAUTION!
Use of the recommended oil and adhering to the
prescribed oil change intervals is important to pre-
vent engine damage and ensure satisfactory starting
in cold conditions.
If Engine Fails To Start
WARNING!
Never pour fuel or other flammable liquids into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in a flash fire causing
serious personal injury.
CAUTION!
•Do not attempt to push or tow your vehicle to get
it started. Vehicles equipped with a Alfa Twin
Clutch Transmission cannot be started this way.
Unburned fuel could enter the catalytic converter
and once the engine has started, ignite and dam-
age the converter and vehicle.
• To prevent damage to the starter, do not continu-
ously crank the engine for more than 15 seconds
at a time. Wait 10 to 15 seconds before trying
again.
After Starting
The idle speed is controlled automatically, and it will
decrease as the engine warms up.
Turbo Charger “Cool Down”
This vehicle is equipped with an after-run pump to cool
the turbocharger after the engine is shut off. Depending
on the type of driving and the amount of cargo, the
pump will run for up to five minutes after the engine
has been shut off to circulate coolant through the
turbocharger.
130 STARTING AND OPERATING

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.
180 IN CASE OF EMERGENCY

WARNING!(Continued)
•Keep hands, tools, clothing, and jewelry away
from the radiator cooling fan when the hood is
raised. The fan starts automatically and may start
at any time, whether the engine is running or not.
• When working near the radiator cooling fan,
disconnect the fan motor lead or turn the ignition
switch to the OFF position. The fan is temperature
controlled and can start at any time the ignition
switch is in the ON position.
Coolant Checks
Check engine coolant (antifreeze) protection every 12
months (before the onset of freezing weather, where
applicable). If the engine coolant (antifreeze) is dirty or
rusty in appearance, the system should be drained,
flushed and refilled with fresh engine coolant (anti-
freeze). Check the front of the A/C condenser for any
accumulation of bugs, leaves, etc. If dirty, clean by
gently spraying water from a garden hose vertically
down the face of the condenser.
Cooling System — Drain, Flush And Refill
NOTE: 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 an local authorized dealer.
If the engine coolant (antifreeze) is dirty or contains
visible sediment, have an authorized dealer clean and
flush with OAT coolant (antifreeze) (conforming to
MS.90032).
Refer to the “Maintenance Plan” in this section for the
proper maintenance intervals.
Selection Of Coolant
Refer to “Fluids And Lubricants” in “Technical Specifi-
cations” for further information.
208 SERVICING AND MAINTENANCE

•Mix a minimum solution of 50% OAT engine coolant
that meets the requirements of FCA Material Stan-
dard MS.90032 and distilled water. Use higher con-
centrations (not to exceed 70%) if temperatures below
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.

210 SERVICING AND MAINTENANCE

WARNING!(Continued)
•Do not use a pressure cap other than the one
specified for your vehicle. Personal injury or
engine damage may result.
Disposal Of Used Coolant
Used ethylene glycol-based coolant (antifreeze) is a
regulated substance requiring proper disposal. Check
with your local authorities to determine the disposal
rules for your community. To prevent ingestion by
animals or children, do not store ethylene glycol-based
coolant in open containers or allow it to remain in
puddles on the ground. If ingested by a child or pet,
seek emergency assistance immediately. Clean up any
ground spills immediately.
Coolant Level
The coolant expansion bottle provides a quick visual
method for determining that the coolant level is ad-
equate. With the engine off and cold, the level of the
engine coolant (antifreeze) in the bottle should be
between the “MIN” and “MAX” marks. As long as the engine operating temperature is satisfac-
tory, the coolant bottle need only be checked once a
month.
When additional engine coolant (antifreeze) is needed
to maintain the proper level, it should be added to the
coolant bottle. Do not overfill.
Points To Remember
NOTE:
When the vehicle is stopped after a few miles/
kilometers of operation, you may observe vapor coming
from the front of the engine compartment. This is
normally a result of moisture from rain, snow, or high
humidity accumulating on the radiator and being va-
porized when the thermostat opens, allowing hot en-
gine coolant (antifreeze) to enter the radiator.
If an examination of your engine compartment shows
no evidence of radiator or hose leaks, the vehicle may
be safely driven. The vapor will soon dissipate.
• Do not overfill the coolant expansion bottle.
• Check the coolant freeze point in the radiator and in
the coolant expansion bottle. If engine coolant (anti-
freeze) needs to be added, the contents of the coolant
expansion bottle must also be protected against freez-
ing.
