ESC SYSTEM
The ESC system improves the
directional control and stability of the
car in various driving conditions.
The ESC system corrects the car’s
understeer and oversteer, distributing
the brake force on the appropriate
wheels. The torque supplied by the
engine can also be reduced in order to
maintain control of the vehicle.
25) 26) 27) 28) 29)
The ESC system comprises the active
safety systems such as: ABS, EBD, ASR,
HILL HOLDER, etc.
The ESC system switches on
automatically when the engine is started
and cannot be switched off.
System intervention
This is indicated by the flashing of the
warning light on the instrument panel, to
inform the driver that the car is in critical
stability and grip conditions.
CBC
(Cornering Braking Control) SYSTEM
This system acts when braking on
corners, optimising the distribution of
brake pressure on the four wheels: the
system prevents the wheels on the
inside of the corner (less affected by the
weight of the car) from locking, ensuring
better stability and direction for the car.
HILL HOLDER SYSTEM
This is an integral part of the ESC system
and facilitates starting on uphill or
downhill slopes by operating the brakes:
IMPORTANT The Hill Holder system is
not a parking brake, therefore do not
leave the car without activating the
handbrake, switched the engine off and
engaged first gear, so that the car is
parked in safety conditions (for further
information read paragraph
“When parked” in the chapter “Starting
and driving”).
IMPORTANT There may be situations on
small gradients (less than 8%), with car
laden, in which the Hill Holder system
may not activate thus causing a slight
reversing motion and increasing the risk
of collision with another vehicle or
object. The driver is, in any case,
responsible for safe driving.
“ELECTRONIC Q2” SYSTEM (“E-Q2”)
The DTC system prevents the drive
wheels from possibly locking, which
could happen, for example, if the
accelerator pedal is released suddenly or
in the case of a sudden downshifting in
conditions of poor grip.
In this conditions, the engine braking
effect could cause the drive wheels to
slip, resulting in a loss of vehicle stability.
In these situations, the DTC system
intervenes, restoring torque to the
engine in order to conserve vehicle
stability and increase vehicle safety.

SAFETY
60
The pretensioner does not require any
maintenance or lubrication: any changes
to its original conditions will invalidate
its efficiency. If, due to unusual natural
events (floods, sea storms, etc.), the
device has been affected by water
and/or mud, contact a dedicated Alfa
Romeo Dealership to have it replaced.
56) 57)

LOAD LIMITERS
To increase protection, the seat belt
retractors contain a device which
controls the force acting on the chest and
shoulders during the belt restraining
action in the event of an accident.
CARRYING CHILDREN
SAFELY
Alfa 4C is a sporty car that can be driven
in town every day, provided its driver and
passengers fasten their seat belts.
Carrying a child on the passenger seat is
also allowed, provided the child weighs
more than 9 kg and a suitable child
restraint system is used.
Children must be suitably restrained
inside the vehicle according to their
weight. Several children restraint system
types are available; always choose the
one most suitable for the child:
58)
When over 1.50 m in height, from the
point of view of restraint systems,
children are considered as adults and
have to wear the standard seat belts.
All restraint devices must bear the
certification data, together with the
control mark, on a label solidly fixed to
the child restraint system which must
never be removed.
Child restraint systems are available
from Lineaccessori Alfa Romeo.
These products have been designed and
tested specifically for Alfa Romeo
vehicles.
56)The pretensioner may be used only
once. After its activation, contact a
dedicated Alfa Romeo Dealership to have
it replaced.
57)Removing or otherwise tampering
with seat belt and pretensioner
components is strictly prohibited. Any
intervention on these components must
be performed by qualified and authorised
technicians. Always contact a dedicated
Alfa Romeo Dealership.
IMPORTANT
4)Operations which lead to knocks,
vibrations or localised heating (over
100°C for a maximum of 6 hours) in the
area around the pretensioners may cause
damage or trigger them.
Contact the dedicated
Alfa Romeo Dealership if there is the need
to operate on those components.

FITTING “UNIVERSAL” CHILD
RESTRAINT SYSTEM
(with seat belts)
Only Group 1, 2 and 3 child restraint
systems, namely forward facing child
restraint systems, can be installed on
Alfa 4C.
This vehicle is NOT compliant for fitting
rear facing child restraint systems on the
passenger seat.
GROUP 1
Children of weight from 9 to 18 kg may
be carried in forward facing child
restraint systems fig. 37.
59)
37A0L0059
GROUP 2
Children from 15 to 36 kg may use the
car seat belts directly, fig. 38.
The child restraint system is used only to
position the child correctly with respect
to the belts so that the diagonal section
crosses the child’s chest and never the
neck, and the horizontal part is snug on
the pelvis not the abdomen.
59)

FUEL CONSUMPTION ACCORDING TO THE CURRENT EUROPEAN DIRECTIVE (litres/100 km)
FUEL CONSUMPTION
The fuel consumption figures given in the table below are determined on the basis of the type-approval tests laid down by specific
European Directives.
The following procedures are used to measure the fuel consumption:
❒ urban cycle: cold starting followed by driving that simulates urban use of the car;
❒ extra-urban cycle: driving that simulates extra-urban use of the car, with frequent acceleration in all gears; the speed varies from
0 to 120 km/h;
❒ combined consumption: this is calculated with a weighting of about 37% urban cycle consumption and about 63% extra-urban
consumption.
IMPORTANT The type of route, traffic situations, weather conditions, driving style, general conditions of the car, trim
level/equipment/accessories, load, climate control system, roof rack, other situations that affect air drag may lead to different fuel
consumption levels than those measured.
