sensor Alfa Romeo 4C Spider 2019 User Guide

WARNING!
Do not mount equipment, or stack luggage or other
cargo up high enough to block the deployment of
the SABICs. The door trim below the side windows
where the SABIC and its deployment path are
located should remain free from any obstructions.
Side Impacts
The Side Air Bags are designed to activate in certain
side impacts. The Occupant Restraint Controller (ORC) determines whether the deployment of the Side Air
Bags in a particular impact event is appropriate, based
on the severity and type of collision. The side impact
sensors aid the ORC in determining the appropriate
response to impact events. The system is calibrated to
deploy the Side Air Bags on the impact side of the
vehicle during impacts that require Side Air Bag occu-
pant protection. In side impacts, the Side Air Bags
deploy independently; a left side impact deploys the
left Side Air Bags only and a right-side impact deploys
the right Side Air Bags only. Vehicle damage by itself is
not a good indicator of whether or not Side Air Bags
should have deployed.
The Side Air Bags will not deploy in all side collisions,
including some collisions at certain angles, or some side
collisions that do not impact the area of the passenger
compartment. The Side Air Bags may deploy during
angled or offset frontal collisions where the front air
bags deploy.
Side Air Bags are a supplement to the seat belt restraint
system. Side Air Bags deploy in less time than it takes to
blink your eyes.

If A Deployment Occurs
The front air bags are designed to deflate immediately
after deployment.
NOTE: Front and/or side air bags will not deploy in all
collisions. This does not mean something is wrong with
the air bag system.
If you do have a collision which deploys the air bags,
any or all of the following may occur:
• The air bag material may sometimes cause abrasions
and/or skin reddening to the occupants as the air
bags deploy and unfold. The abrasions are similar to friction rope burns or those you might get sliding
along a carpet or gymnasium floor. They are not
caused by contact with chemicals. They are not
permanent and normally heal quickly. However, if
you haven’t healed significantly within a few days,
or if you have any blistering, see your doctor imme-
diately.
• As the air bags deflate, you may see some smoke-like
particles. The particles are a normal by-product of the
process that generates the non-toxic gas used for air
bag inflation. These airborne particles may irritate
the skin, eyes, nose, or throat. If you have skin or eye
irritation, rinse the area with cool water. For nose or
throat irritation, move to fresh air. If the irritation
continues, see your doctor. If these particles settle on
your clothing, follow the garment manufacturer ’s
instructions for cleaning.
Do not drive your vehicle after the air bags have
deployed. If you are involved in another collision, the
air bags will not be in place to protect you.

To Accelerate For Passing
Press the accelerator as you would normally. When the
pedal is released, the vehicle will return to the set speed.
To Resume Speed
To resume a previously set speed, push the CANCEL/
RESUME button, located on the end of the speed
control stalk, and release. Resume can be used at any
speed above 18 mph (30 km/h).
To Deactivate
A soft tap on the brake pedal, pushing the CANCEL/
RESUME button on the end of the stalk, or normal
brake pressure while slowing the vehicle will deactivate
the Speed Control without erasing the set speed
memory. Rotating the end of the multifunction lever to
the O (off) position, or turning the ignition switch to
OFF, erases the set speed memory.
PARKING SENSORS — IF EQUIPPED
The vehicle’s parking sensors are located in the rear
bumper, and will detect the presence of any obstacles
near the rear part of the vehicle while moving in
REVERSE gear. The driver is then informed through an
intermittent acoustic signal.
Parking Sensors
6
STARTING AND OPERATING 153

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 ob-
stacle decreases, culminating in a continuous acous-
tic signal when the distance is less than approxi-
mately 12 inches (30 cm).
• 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 con-
cerns the side sensors, the signal will stop after
approximately 3 seconds, for example, in the event of
parking 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 parking sensor
display screen appears in the instrument cluster.
Obstacle presence and distance information is therefore
provided both by the acoustic signal and the instrument
cluster 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 Sensor Display Screen
154 STARTING AND OPERATING

If an obstacle is detected in the rear central area, the
instrument cluster 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 instrument cluster display depends on
the distance from and position of the obstacle.
The vehicle is close to the obstacle when the instrument
cluster display shows a single constant arc and emits a
continuous sound.
If there are several obstacles, the closest one is indi-
cated.
Activation/Deactivation
The sensors are automatically activated when REVERSE
gear is engaged and a visual display will appear in the
instrument cluster display. As the obstacle behind the
vehicle gets closer, the acoustic signal becomes more
frequent.
Fault Indication
Parking sensor failures, if any, will be indicated when
REVERSE gear is engaged by the illumination of the
warning light in the instrument cluster 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
sensitivity of the sensor itself and therefore reduce
the system performance.
• 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.

STARTING AND OPERATING 155

•The variation in sensor position, caused by variation
in ride (due to suspension component wear), chang-
ing 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 shampoo 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 inches (10 cm) away. Also, do not
apply stickers to the sensors.
WARNING!
Drivers must be careful when backing up even
when using the Parking Sensor system. Always
check carefully behind your vehicle, and be sure to
check for pedestrians, animals, other vehicles, ob-
structions, or blind spots before backing up. You
are responsible for the safety of your surroundings
(Continued)
WARNING! (Continued)
and must continue to pay attention while backing
up. Failure to do so can result in serious injury or
death.
CAUTION!
•The Parking Sensor system is only a parking aid
and it is unable to recognize every obstacle,
including small obstacles. Parking curbs might be
temporarily detected or not detected at all. Ob-
stacles located above or below the sensors will
not be detected when they are in close proximity.
• 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
recommended that the driver looks over his/her
shoulder when using the Parking Sensor system.
PARKVIEW REAR BACK UP CAMERA
The ParkView Rear Back Up Camera allows you to see
an on-screen image of your vehicle’s rear surroundings
when the gear selector is put into REVERSE. The image

is very important. Increased tire pressure and reduced
vehicle loading may be required for high-speed vehicle
operation. Refer to an authorized tire dealer or original
equipment vehicle dealer for recommended safe oper-
ating speeds, loading and cold tire inflation pressures.
WARNING!
High speed driving with your vehicle under maxi-
mum load is dangerous. The added strain on your
tires could cause them to fail. You could have a
serious collision. Do not drive a vehicle loaded to
the maximum capacity at continuous speeds above
75 mph (120 km/h).
Radial Ply Tires
WARNING!
Combining radial ply tires with other types of tires
on your vehicle will cause your vehicle to handle
poorly. The instability could cause a collision. Al-
ways use radial ply tires in sets of four. Never
combine them with other types of tires.Tire Repair
If your tire becomes damaged, it may be repaired if it
meets the following criteria:
•
The tire has not been driven on when flat.
• The damage is only on the tread section of your tire
(sidewall damage is not repairable).
•
The puncture is no greater tha na¼ofaninch (6 mm).
Consult an authorized tire dealer for tire repairs and
additional information.
Damaged Run Flat tires, or Run Flat tires that have
experienced a loss of pressure should be replaced
immediately with another Run Flat tire of identical size
and service description (Load Index and Speed Sym-
bol). Replace the tire pressure sensor as well as it is not
designed to be reused.
Run Flat Tires — If Equipped
Run Flat tires allow you the capability to drive 50 miles
(80 km) at 50 mph (80 km/h) after a rapid loss of
inflation pressure. This rapid loss of inflation is referred
to as the Run Flat mode. A Run Flat mode occurs when
the tire inflation pressure is of/or below 14 psi (96 kPa).
Once a Run Flat tire reaches the run flat mode it has
8
SERVICING AND MAINTENANCE 237

limited driving capabilities and needs to be replaced
immediately. A Run Flat tire is not repairable. When a
run flat tire is changed after driving with underinflated
tire condition, please replace the TPM sensor as it is not
designed to be reused when driven under run flat mode
(14 psi (96 kPa)) condition.
NOTE:TPM Sensor must be replaced after driving the
vehicle on a flat tire condition.
It is not recommended driving a vehicle loaded at full
capacity or to tow a trailer while a tire is in the run flat
mode.
See the tire pressure monitoring section for more infor-
mation.Tire Spinning
When stuck in mud, sand, snow, or ice conditions, do
not spin your vehicle’s wheels above 30 mph (48 km/h)
or for longer than 30 seconds continuously without
stopping.
Refer to “Freeing A Stuck Vehicle” in “In Case Of
Emergency” for further information.
WARNING!
Fast spinning tires can be dangerous. Forces gener-
ated by excessive wheel speeds may cause tire
damage or failure. A tire could explode and injure
someone. Do not spin your vehicle’s wheels faster
than 30 mph (48 km/h) for more than 30 seconds
continuously when you are stuck, and do not let
anyone near a spinning wheel, no matter what the
speed.
