2015 Alfa Romeo 4C ABS

“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.
45

37) For the correct operation of the
ABS, 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.
38) The ASR system can’t overrule
the natural laws of physics, and
can’t increase the grip available
according to the condition of
the road.
39) The ASR system cannot prevent
accidents, including those due to
excessive speed on corners,
driving on low-grip surfaces or
aquaplaning.
40) The capability of the ASR system
must never be tested irresponsibly
and dangerously, in such a way
as to compromise personal safety
and the safety of others.
41) The HBA system can’t overrule
the natural laws of physics, and
can’t increase the grip available
according to the condition of
the road.
42) The HBA system cannot prevent
accidents, including those due to
excessive speed on corners,
driving on low-grip surfaces or
aquaplaning.43) The capability of the HBA system
must never be tested irresponsibly
and dangerously, in such a way
as to compromise the safety of
the driver, the other occupants of
the car or any other road user.“Alfa DNA” SYSTEM
(Dynamic car
control system)
This device allows, using lever A fig. 47
(on the central tunnel), four car
response modes to be selected
according to driving style and road
conditions:
❒d=DynamicorRace(sports driving
mode);
❒n=Natural(mode for driving in
normal conditions);
❒a=All Weather(mode for driving in
poor grip conditions, such as rain
and snow).
The device also acts on the dynamic
car control systems (engine,
gearbox/transmission, ESC system).

GETTING TO KNOW YOUR CAR

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.

WARNING
59) If thewarning light does not switch on when the key is turned to MAR-ON or if it stays on when driving (together
with the message on the display), there may be a fault in the restraint systems; in this case, the airbags or
pretensioners may not deploy in the event of an accident or, in a lower number of cases, they could deploy
erroneously. Before proceeding, contact the dedicated Alfa Romeo Dealership to have the system checked
immediately.
60) Failure of the
warning light is signalled by the flashing for longer than the usual 4 seconds of thewarning
light. In addition, the airbag system automatically disables the passenger side airbag. In this case, the
warning
light may not indicate a fault in the restraint systems. Before proceeding, contact the dedicated Alfa Romeo
Dealership to have the system checked immediately.
Warning lights on
panelWhat it means What to do
amberABS FAILURE
When the key is turned to MAR-ON, the warning
light switches on but should switch off after a few
seconds.
The warning light switches on to indicate a
system fault. In this case the braking system will
work as normal, but without the extra
performance offered by the ABS.
The display shows the dedicated message.Drive carefully and contact the dedicated Alfa
Romeo Dealership as soon as possible.

9) When the engine is off, do not
leave the ignition key turned to
MAR-ON to prevent unnecessary
electrical consumption from
draining the battery.
10) A quick burst on the accelerator
before turning off the engine
serves absolutely no practical
purpose; it wastes fuel and is
especially damaging to
turbocharged engines.PARKING
Always remove the ignition key when
leaving the car.
When parking and leaving the car,
proceed as follows:
❒engage a gear (first gear if parked
uphill or reverse if facing downhill)
and leave the wheels turned;
❒stop the engine and engage the
handbrake.
Block the wheels with a wedge or a
stone if the car is parked on a steep
slope.
Wait until the indication of the gear
engaged disappears on the display
before releasing the brake pedal.
87)
IMPORTANT:NEVERleave the car with
the gearbox in neutral.
HANDBRAKE
To engage it, pull lever A fig. 73
upwards until the car is secured. When
the handbrake is engaged and the
ignition key is at MAR-ON, the
warning light will switch on in the
instrument panel.
To release the handbrake, raise lever A
slightly, hold down button B and lower
the lever. The
warning light in the
instrument panel will switch off.Four or five clicks are generally enough
when the car is on level ground, while
ten or eleven may be required if the car
is on a steep slope and laden.
88)
IMPORTANT Carry out these
manoeuvres with the brake pedal
pressed.
WARNING
87) Never leave children unattended
in the car. Always remove the key
from the ignition device when
leaving the car and take it with
you.

DRIVING STYLE
Starting
Do not warm the engine with the car at
a standstill or at idle or high speed:
under these conditions the engine
warms up much more slowly, increasing
consumption and emissions. It is
therefore advisable to move off
immediately, slowly, avoiding high
speeds: in this way the engine will
warm up more quickly.
Unnecessary actions
Avoid accelerating when stopped at
traffic lights or before switching off the
engine. This action is absolutely
pointless and only increases
consumption and pollution.
Gear selection
Using a low gear for faster acceleration
increases consumption.
In the same way, improper use of a high
gear increases consumption,
emissions and engine wear.Max. speed
Fuel consumption increases
considerably with speed. Maintain a
constant speed, avoiding unnecessary
braking and acceleration, which cost
in terms of both fuel consumption and
emissions.
Acceleration
Accelerating violently will greatly affect
consumption and emissions: avoid
frequent and strong accelerations.
CONDITIONS OF USE
Cold starting
Short journeys and frequent cold starts
do not allow the engine to reach
optimum operating temperature.
This results in a significant increase in
consumption levels (from +15 to +30%
on the urban cycle) and emissions.
Traffic and road
conditions
Rather high consumption levels are
linked to situations with heavy traffic, for
instance when travelling in queues
with frequent use of the lower gears or
in cities with many traffic lights.Stops in traffic
During prolonged hold-ups (e.g. level
crossings) the engine should be
switched off.

STARTING AND DRIVING

WARNING
115) Before towing, turn the ignition
key to MAR-ON and then to STOP
without removing it. The steering
column will automatically lock
when the key is removed and the
wheels cannot be steered. Also
check that the gearbox/
transmission is in neutral (N).
116) When towing, remember that
the assistance of the brake servo
is absent. Consequently, more
force is required at the pedal
in order to brake. Do not
use flexible cables when towing
and avoid jerky movements. Make
sure not to damage parts in
contact with the car while towing.
When towing the car, you must
comply with all specific traffic
regulations, both in terms of the
towing device and behaviour
on the road. Do not start the
engine while towing the car.
Before tightening the ring, clean
the threaded housing thoroughly.
Make sure that the ring is fully
screwed into the housing before
towing the car.117) The tow hook must be used
exclusively for roadside
assistance operations. You are
allowed to tow the vehicle for
short distances using an
appropriate device in accordance
with the highway code (a rigid
bar), to move the vehicle on the
road in readiness for towing or
transport via a breakdown vehicle.
Tow hooks MUST NOT be used
to tow vehicles off the road or
where there are obstacles and/or
for towing operations using cables
or other non-rigid devices. In
compliance with the above
conditions, towing must take
place with the two vehicles (one
towing, the other towed) aligned
as much as possible along the
same centre line.
