2016 Alfa Romeo 4C Spider Owner's Manual

The speed decrement shown is dependant on the speed
of U.S. (mph) or Metric (km/h) units:
U.S. Speed (mph)
•Tapping the Speed Control lever down (-) once will
result in a 1 mph decrease in set speed. Each subse-
quent tap of the lever results in a decrease of 1 mph.
• If the lever is continually held down, the set speed will
continue to decrease until the lever is released, then
the new set speed will be established. Metric Speed (km/h)
•
Tapping the Speed Control lever down (-) once will
result in a 2 km/h decrease in set speed. Each subse-
quent tap of the lever results in a decrease of 2 km/h.
• If the lever is continually held down, the set speed will
continue to decrease until the lever is released, then
the new set speed will be established.
To Accelerate For Passing
Press the accelerator as you would normally. When the
pedal is released, the vehicle will return to the set speed.

PARKING SENSORS — IF EQUIPPED
They are located in the rear bumper and their function is
to detect the presence of any obstacles near the rear part
of the vehicle; they consequently inform the driver,
through an intermittent acoustic signal.
Activation/Deactivation
The sensors are automatically activated when reverse
gear is engaged. As the obstacle behind the vehicle gets
closer, the acoustic signal becomes more frequent.
Acoustic Signal
When reverse gear is engaged and there is an obstacle
behind the vehicle, an acoustic signal is emitted which
varies according to the distance of the bumper from the
obstacle.
The frequency of the acoustic signal:
•Increases as the distance between vehicle and obstacle
decreases, culminating in a continuous acoustic signal
when the distance is less than approximately 12 in
(30 cm).
Parking Sensors
104 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

•Decreases if the distance from the obstacle increases,
until the signal ceases entirely.
• Remains constant if the distance between vehicle and
obstacle remains unchanged; if this situation concerns
the side sensors, the signal will stop after approxi-
mately 3 seconds to avoid, for example, indications in
the event of manoeuvres along a wall.
If several obstacles are detected by the sensors, only the
nearest one is considered.
Indications On Display — If Equipped
When the sensors are activated, the screen appears on the
display. Obstacle presence and distance information is therefore
provided both by the acoustic signal and the instrument
panel display.
The system indicates a detected obstacle by displaying an
arc in one or more positions according to the distance of
the obstacle and its position in relation to the vehicle.Parking Sensors Screen

UNDERSTANDING THE FEATURES OF YOUR VEHICLE 105

If an obstacle is detected in the rear central area, the
display shows all the arcs in the rear central area, up to
the one that corresponds to the position of the obstacle
itself.
The signal is similar for obstacles in the rear left or right
area.
The arc that corresponds to the position of the obstacle
will flash.
The color on the display depends on the distance from
and position of the obstacle.
The vehicle is close to the obstacle when the display
shows a single constant arc and emits a continuous
sound.
If there are several obstacles, the closest one is indicated.Fault Indication
Parking sensor failures, if any, will be indicated when
reverse is engaged by the switching on of the
warn-
ing light on the instrument panel together with the
message on the display.
General Warnings
When parking, take the utmost care over obstacles that
may be above or under the sensor.
Under certain circumstances, objects close to the vehicle
are not detected by the system and could therefore cause
damage to the vehicle or be damaged themselves.
Some conditions may influence the performance of the
parking sensors:
• The presence of ice, snow, mud or multiple layers of
paint on the sensor surface may cause reduced sensi-
tivity of the sensor itself and therefore reduce the
system performance.
106 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

•Mechanical interference (e.g washing the vehicle, rain,
strong wind, hail) may cause the sensor to detect a
non-existent obstacle (“echo interference”).
• The presence of ultrasonic systems (e.g. pneumatic
brake systems of trucks or pneumatic drills) near the
vehicle could alter the signals sent by the sensor.
• The variation in sensor position, caused by variation in
ride (due to suspension component wear), changing
tires, overloaded vehicle, or tuning that lowers the
vehicle, for example, may affect parking sensor system
performance. NOTE:The sensor must be free from mud, dirt snow or
ice in order for the system to operate correctly. Be careful
not to scratch or damage the sensors while cleaning them.
Avoid using dry, rough or hard cloths. The sensors must be
washed using clean water, with the addition of car sham-
poo if necessary. When using special washing equipment
such as high pressure jets or steam cleaning, clean the
sensors very quickly keeping the jet more than 4 in (10 cm)
away. Also, do not apply stickers to the sensors.
CAUTION!
• The Parking Sensor system is only a parking aid
and it is unable to recognize every obstacle, includ-
ing small obstacles. Parking curbs might be tem-
porarily detected or not detected at all. Obstacles
located above or below the sensors will not be
detected when they are in close proximity

CAUTION!(Continued)
•The vehicle must be driven slowly when using the
Parking Sensor system in order to be able to stop in
time when an obstacle is detected. It is recom-
mended that the driver looks over his/her shoulder
when using the Parking Sensor system.
WARNING!
Drivers must be careful when backing up even when
using the Parking Sensor system. Always check care-
fully behind your vehicle, and be sure to check for
pedestrians, animals, other vehicles, obstructions, or
blind spots before backing up. You are responsible
for the safety of your surroundings and must con-
tinue to pay attention while backing up. Failure to do
so can result in serious injury or death.
POWER OUTLETS
Your vehicle is equipped with a 12 Volt (13 Amp) power
outlet that can be used to power cellular phones, small
electronics and other low powered electrical accessories.
Front Power Outlet
108 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

The power outlet is located on the central tunnel, be-
tween the two cup holders. It only operates with the
ignition key at MAR-ON.WARNING!
To avoid serious injury or death:
•Only devices designed for use in this type of outlet
should be inserted into any 12 Volt outlet.
• Do not touch with wet hands.
• Close the lid when not in use and while driving the
vehicle.
• If this outlet is mishandled, it may cause an electric
shock and failure.
CAUTION!
• Many accessories that can be plugged in draw
power from the vehicle’s battery, even when not in
use (i.e., cellular phones, etc.). Eventually, if
plugged in long enough, the vehicle’s battery will
discharge sufficiently to degrade battery life and/or
prevent the engine from starting.

UNDERSTANDING THE FEATURES OF YOUR VEHICLE 109

CAUTION!(Continued)
•Accessories that draw higher power (i.e., coolers,
vacuum cleaners, lights, etc.) will degrade the bat-
tery even more quickly. Only use these intermit-
tently and with greater caution.
• After the use of high power draw accessories, or
long periods of the vehicle not being started (with
accessories still plugged in), the vehicle must be
driven a sufficient length of time to allow the
generator to recharge the vehicle’s battery.
CAUTION!
• Do not exceed the maximum power of 180 Watts (15
Amps) at 12 Volts. If the 180 Watts (15 Amps) power
rating is exceeded, the fuse protecting the system
will need to be replaced.
(Continued)
CAUTION! (Continued)
•Power outlets are designed for accessory plugs
only. Do not insert any other object in the power
outlets as this will damage the outlet and blow the
fuse. Improper use of the power outlet can cause
damage not covered by your New Vehicle Limited
Warranty.
CIGAR LIGHTER AND ASH RECEIVER — IF
EQUIPPED
The cigar lighter and ash receiver are located on the
central tunnel. To activate the cigar lighter, push the
button down. After a few seconds the button automati-
cally returns to its initial position, and the cigar lighter is
ready for use.
