2018 Alfa Romeo 4C overheating

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

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.

Tires — General Information
Tire Pressure
Proper tire inflation pressure is essential to the safe and
satisfactory operation of your vehicle. Four primary
areas are affected by improper tire pressure:
•Safety and Vehicle Stability
• Economy
• Tread Wear
• Ride Comfort
Safety
WARNING!
• Improperly inflated tires are dangerous and can
cause collisions.
• Underinflation increases tire flexing and can re-
sult in overheating and tire failure.
• Overinflation reduces a tire’s ability to cushion
shock. Objects on the road and chuckholes can
cause damage that result in tire failure.
(Continued)
WARNING! (Continued)
•Overinflated or underinflated tires can affect ve-
hicle handling and can fail suddenly, resulting in
loss of vehicle control.
• Unequal tire pressures can cause steering prob-
lems. You could lose control of your vehicle.
• Unequal tire pressures from one side of the ve-
hicle to the other can cause the vehicle to drift to
the right or left.
• Always drive with each tire inflated to the recom-
mended cold tire inflation pressure.
Both under-inflation and over-inflation affect the stabil-
ity of the vehicle and can produce a feeling of sluggish
response or over responsiveness in the steering.
NOTE:
• Unequal tire pressures from side to side may cause
erratic and unpredictable steering response.
• Unequal tire pressure from side to side may cause the
vehicle to drift left or right.
Fuel Economy
Underinflated tires will increase tire rolling resistance
resulting in higher fuel consumption.
