“ELECTRONIC Q2” SYSTEM (“E-Q2”)
The “Electronic Q2” system uses the braking system to create an
effect similar to a limited slip differential.
The front braking circuit, when accelerating around a corner, acts
on the inside wheel to increase the drive to the outside wheel (in-
creased load), dynamically and continuously distributing the torque
between the front drive wheels according to driving and road con-
ditions.
The system, combined with Mc Pherson front suspension, allows
particularly effective, sporty driving.
DST SYSTEM (Dynamic Steering Torque)
This function integrates Dual Pinion active steering into the opera-
tion of VDC. For particular manoeuvres, VDC controls the steering
to actuate a steering torque and assist the driver in the best pos-
sible way. The system operates the brakes and steering in a coor-
dinated manner to increase the suspension and safety level of the
car as a whole. The steering provides addition torque on the steer-
ing wheel.
RAB SYSTEM (Ready Alert Brake)
(“Dynamic” mode only)
By pre-approaching the brake pads (front and rear) after rapid ac-
celerator release, this function provides prompter braking and re-
duces stopping distance.
BRAKE ASSIST
(emergency braking assistance)
The system, which cannot be turned off, recognises emergency
braking (on the basis of the brake pedal operating speed) and
speeding up the response of the braking system. The Brake
Assist function is deactivated in the event of VDC system fault.
MSR SYSTEM
(Motor Schleppmoment Regelung)
This system is an integral part of the ABS, that intervenes, if there
is a sudden change to a lower gear, restoring torque to the engine,
thereby preventing excessive drive at the drive wheels which, es-
pecially in poor grip conditions, could lead to a loss in stability.
CBC SYSTEM (Cornering Braking Control)
This system improves the distribution of the braking pressure at the
four wheels (to fully exploit the grip available on the ground) when
braking round bends when the ABS intervenes. This improves stop-
ping distances and above all vehicle stability when cornering.

The ultimate responsibility when parking and car-
rying out other dangerous manoeuvres still rests
with the driver. When carrying out such manoeu-
vres, always ensure that the manoeuvring area is free
of people (particularly children) and animals. Parking sen-
sors are designed to assist drivers; however, you must al-
ways concentrate fully during potentially dangerous ma-
noeuvres, even if carried out at low speeds.
GENERAL WARNINGS
During parking manoeuvres, pay the utmost attention to any ob-
stacles that could be located above or below the sensors.
Sometimes, objects located close to the rear part of the car may
not be detected by the system and may damage the car or become
damaged themselves.
Here below are some conditions that may influence the perfor-
mance of the parking system:
❍Reduced sensor sensitivity and a reduction in the parking as-
sistance system performance could be due to the presence on
the surface of the sensor of: ice, snow, mud, thick paint.
❍the sensor may detect a non-existent obstacle (echo noise) due
to mechanical noises, for example when washing the vehicle,
in case of rain, strong wind, hail.
❍the signals sent by the sensors can also be altered by the pres-
ence of ultrasound devices (e.g. pneumatic brake systems or
pneumatic drills) near the car;
❍sensor performance can also be influenced by the position of
the sensors. For example by a change in the ride setting (caused
by the wear of the shock absorbers, suspension), overloading
the car and carrying out specific tuning operations that require
the car to be lowered;
❍the detection of obstacles at the top part of the vehicle may
not be guaranteed because the system detects obstacles that
could cause an impact with the vehicle in the bottom part.
For repainting the bumpers or retouching the paint-
work around the sensors contact Alfa Romeo
Authorized Services. Incorrect application of paint
may compromise the operation of the parking sensors.
