2015 Alfa Romeo 4C brake

“ELECTRONIC Q2”
SYSTEM (“E-Q2”)
The "Electronic Q2" system intervenes
during acceleration on corners, braking
the inner drive wheel and thus
increasing the traction of the outer
wheel (which bears more of the car’s
weight): the torque is thus distributed
optimally between the drive wheels
in accordance with the driving
conditions and road surface, permitting
particularly effective, sporty driving.
"PRE-FILL" SYSTEM
(RAB - Ready Alert
Brake)
(only with “Dynamic” or "Race" mode
activated)
This function activates automatically if
the accelerator pedal is released
rapidly, reducing the brake pad travel
(both at front and back), with the aim of
preparing the braking system and
enhancing its responsiveness, thus
reducing the stopping distance in the
event of subsequent braking.
WARNING
26) The ESC can’t alter the natural
laws of physics, and can’t
increase grip, which depends on
the condition of the road.
27) The ESC system cannot prevent
accidents, including those due to
excessive speed on corners,
driving on low-grip surfaces or
aquaplaning.
28) The capability of the ESC system
must never be tested irresponsibly
and dangerously, in such a way
as to compromise personal safety
and the safety of others.
29) For the correct operation of the
ASR system, the tyres must of
necessity be the same make and
type on all wheels, in perfect
condition and, above all, of the
prescribed type and dimensions. .
30) The performance of the ESC
and ASR systems must not
encourage the driver to take
unnecessary risks. Your driving
style must always be suited to the
road conditions, visibility and
traffic. The driver is, in any case,
responsible for safe driving.31) When the ABS intervenes and
you feel the brake pedal pulsating,
do not reduce the pressure, but
hold it down firmly and
confidently; in doing so you will
brake in the shortest distance
possible, depending on the
current road conditions.
32) For maximum efficiency of the
braking system, a bedding-in
period of about 500 km is
required: during this period it is
advisable to avoid sharp, repeated
and prolonged braking.
33) If the ABS intervenes, this
indicates that the grip of the tyres
on the road is nearing its limit:
you must slow down to a speed
compatible with the available grip.
34) The ABS can’t overrule the
natural laws of physics, and can’t
increase the grip available
according to the condition of the
road.
35) The ABS cannot prevent
accidents, including those due to
excessive speed on corners,
driving on low-grip surfaces or
aquaplaning.
36) The capability of the ABS must
never be tested irresponsibly and
dangerously, in such a way as
to compromise personal safety
and the safety of others.

Activation
Move the lever A fig. 47 upwards (to the
letter “d”) and hold in this position for
5 seconds, until the "Race" mode
activation indicator appears on the
display. When "Race" mode is
activated, the longitudinal/lateral
accelerometer indicator screen
(G-meter information) is displayed
automatically. This considers
gravitational acceleration (G) fig. 50.
ESC and ASR systems:the systems
are deactivated in order to ensure
the fullest sensation of sport, leaving
the driver in full control of the vehicle.
When the vehicle is in unstable
conditions, the ESC reactivates
automatically when the brake pedal is
pressed until the ABS intervenes,
thus returning the vehicle to stable
conditions."Electronic Q2" system:the system
is calibrated to increase traction whilst
accelerating on bends, improving
the agility of the car.
Engine and gearbox/transmission:
adoption of sports mapping.
IMPORTANT In "Race", the sensitivity of
the accelerator pedal increases
considerably. Consequently, driving is
less fluid and comfortable.
IMPORTANT In "Race" mode the
transmission only works in MANUAL
mode. For further details, refer to the
"Using the transmission" section in
chapter "Starting and driving".
Deactivation
To deactivate "Race" mode and return
to "Dynamic", move lever A fig. 47
downwards (to letter “a”) and keep it in
this position for half a second. In this
case, the LED corresponding to
"Dynamic" mode will light up and the
"Dynamic" mode activation indication
will appear on the display.“All Weather” MODE
Activation
Move the lever A fig. 47 downwards (to
the letter “a”) and hold in this position
for half a second, until the
corresponding LED lights up and the
“All Weather” mode activation indicator
appears on the display.
ESC and ASR systems:intervention
thresholds aimed at ensuring maximum
safety in low-grip driving conditions. It
is advisable to select "All Weather"
mode in the presence of low-grip road
surfaces.
"ELECTRONIC Q2" SYSTEM: the
system is deactivated.
Engine and gearbox/transmission:
standard response.

GETTING TO KNOW YOUR CAR
“Race” MODE

Fiat Group Automobiles S.p.A.
authorises the installation of transceiver
devices on condition that such
installations are carried out in
a workmanlike fashion, following the
manufacturer’s instructions, at a
specialised centre.
IMPORTANT Traffic police may not
allow the car on the road if devices
have been installed which modify the
features of the car. This may also cause
invalidation of warranty in relation to
faults caused by the change either
directly or indirectly related to it.
Fiat Group Automobiles S.p.A. shall not
be liable for damage caused by the
installation of accessories either not
supplied or recommended by Fiat
Group Automobiles S.p.A. and/or not
installed in compliance with the
provided instructions.
RADIO TRANSMITTERS
AND MOBILE PHONES
Radio transmitter equipment (vehicle
mobile phones, CB radios, amateur
radio etc.) cannot be used inside the
car unless a separate aerial is mounted
on the roof.IMPORTANT The use of these devices
inside the passenger compartment
(without a separate aerial) may cause
the vehicle’s electronic systems to
malfunction. This could compromise
safety in addition to constituting a
potential hazard for passengers' health.
As far as the use of EC-approved
mobile phones is concerned (GSM,
GPRS, UMTS), follow the usage
instructions provided by the mobile
phone manufacturer.
WARNING
44) Take care when fitting additional
spoilers or non-standard alloy
wheels: they could reduce the
ventilation of the brakes and
affect efficiency in sharp,
repeated braking or on long
descents. Make sure that nothing
obstructs the pedal stroke (mats,
etc.).
PARKING SENSORS
(for versions/markets, where provided)
They are located in the rear bumper
fig. 53 and their function is to detect the
presence of any obstacles near the
rear part of the car; 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 car gets closer, the
acoustic signal becomes more
frequent.
53A0L0043
51

Under certain circumstances, objects
close to the vehicle are not detected by
the system and could therefore cause
damage to the car 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 car, 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
car could alter the signals sent by the
sensor;
❒the variation in sensor position,
caused by variation in ride (due
to suspension component wear),
changing tyres, overloaded car,
or tuning that lowers the car, for
example, may affect parking sensor
system performance.
WARNING
45) The responsibility for parking
and other dangerous manoeuvres
always and in every case lies
with the driver. While carrying out
these manoeuvres, always make
sure that no people (especially
children) or animals are in the
area concerned. The parking
sensors are an aid for the driver,
but must never allow their
attention to lapse during
potentially dangerous
manoeuvres, even those executed
at low speeds.
IMPORTANT
4) 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 10 cm away. Also, do not
apply stickers to the sensors.
