2015 Alfa Romeo 4C dimensions

“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

135) The car is always equipped with
front and rear wheels of different
dimensions. It is not therefore
possible to move the wheels from
the front to the back and vice
versa.WINDSCREEN
WIPER
It is advisable to replace the blade
about once a year.
136)
A few simple precautions can reduce
the possibility of damage to the blade:
❒if the temperature falls below zero,
make sure that ice has not frozen
the rubber to the glass. Use an
antifreeze product to release it if
required;
❒remove any snow from the glass;
❒do not operate the windscreen wiper
on dry glass.
IMPORTANT Do not lift the arm of the
windscreen wiper when it is in its initial
rest position. Refer to the following
instructions to lift the windscreen wiper
blade correctly.
Lifting blade
If it is necessary to lift the blade from
the windscreen (e.g. in the event of
snow or if the blade needs
replacement) proceed as follows:
❒turn ring nut A fig. 129 to
(wiper
off);
❒turn the ignition key to MAR-ON and
then to STOP;❒after turning the ignition key to STOP,
within 2 minutes move the right stalk
upwards, into unstable ("anti-panic")
position, for at least half a second.
The windscreen wiper then executes
part of a stroke; at each command,
approximately 1/3 of a normal wiper
stroke is triggered.
❒the previous operation can be
repeated up to 3 times, in order to
move the blade to the most suitable
position;
❒lift the blade from the windscreen and
proceed with the required operation;
❒lower the blade, bringing it into
contact with the windscreen;
❒bring the blade to the initial rest
position, turning the ignition key
to MAR-ON.
