ESC (Electronic Stability
Control) SYSTEM
This is an electronic system that controls vehicle stability in the event of
tyre grip loss, helping maintain directional control.
The system is capable of recognising potentially dangerous situations
in terms of the stability and intervenes automatically on the brakes in a
differentiated manner for the four wheels in order to provide a
stabilising torque.
The ESC system also includes the following systems:
❒Hill Holder
❒ASR
❒Brake Assist
❒MSR
❒CBC
❒“ELECTRONIC Q2” (“E-Q2”)
❒DST
SYSTEM ACTIVATION
The ESC system switches on automatically when the engine is started
and cannot be switched off.
SYSTEM INTERVENTION
It is signalled by the blinking of the warning lighton the instrument
panel, to inform the driver that the car is in critical stability and grip
conditions.
HILL HOLDER SYSTEM
This system is an integral part of the ESC system and facilitates starting
on slopes.
It is automatically activated in the following conditions:
❒uphill: vehicle stationary on a road with a gradient higher than 5%,
engine running, brake pedal pressed and gearbox in neutral or
gear (other than reverse) engaged;
❒downhill: vehicle stationary on a road with a gradient higher than
5%, engine running, brake pedal pressed and reverse gear
engaged.
When setting off the ESC system control unit maintains the braking
pressure at the wheels until the engine torque required for departure is
reached or for approximately 2 seconds, allowing your right foot to
be moved easily from the brake pedal to the accelerator.
If the vehicle has not departed after this time, the system will deactivate
automatically by gradually releasing the brake force. A sound may
be heard during this stage: this indicates that the vehicle is about
to move off.
IMPORTANT The Hill Holder system is not a handbrake. Do not leave
the vehicle without having engaged the handbrake, switched off the
engine and engaged a gear.

ASR (AntiSlip Regulation) SYSTEM
It is an integral part of the ESC system. It automatically operates in the
event of one or both drive wheels slipping, loss of grip on wet roads
(aquaplaning) and acceleration on slippery, snowy or icy roads, etc.
Depending on the slipping conditions, two different control systems are
activated:
❒if the slipping involves both drive wheels, the ASR intervenes
reducing the power transmitted by the engine;
❒if the slipping only involves one of the drive wheels, the ASR
intervenes automatically braking the wheel that is slipping.
For the ESC and ASR systems to function correctly, all
four tyres must be the same brand and type, must
be in excellent condition and, above all, must be of the
prescribed type and size.
The ESC system operates even when the space-saver
wheel is being used. Always remember that the
space-saver wheel, being smaller than the original
wheel, provides less grip.
The performance of the ESC and ASR systems must not
encourage the driver to take unnecessary risks. Driving
style must always be adapted to road conditions,
visibility and traffic. The driver is, in any case, responsible for
safe driving.
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 device is
deactivated if there is a ESC system failure.
MSR (Motor Schleppmoment
Regelung) SYSTEM
This system is an integral part of the ABS, that intervenes, if there is a
sudden downshifting, restoring torque to the engine, thereby
preventing excessive drive at the drive wheels which, especially in poor
grip conditions, could lead to a loss in stability of the car.
CBC (Cornering Brake Control)
SYSTEM
This function improves the distribution of the braking pressure at the
four wheels (to fully exploit the grip available on the ground) when
braking on bends if the ABS intervenes. This improves stopping
distances and above all vehicle stability when cornering.
“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 system, when accelerating around a curve, acts on
the inside wheel to increase the drive to the outside wheel (increased
load), dynamically and continuously distributing the torque between
the front drive wheels according to driving and road conditions.
The system, combined with MacPherson front suspension, allows
particularly effective and sports driving to be achieved.

DST SYSTEM (Dynamic Steering
Torque)
This function integrates Dual Pinion active steering into the operation of
ESC. For particular manoeuvres, the ESC system controls the steering
to actuate a steering torque and assist the driver in the best possible
way.
The system operates the brakes and steering in a coordinated manner
to increase the suspension and safety level of the car as a whole.
The steering provides additional torque on the steering wheel.
“Alfa DNA” SYSTEM (Car
dynamic control system)
This device allows, using lever A fig. 74 (on the central tunnel), three
car response modes to be selected according to driving style and road
conditions:
❒d = Dynamic (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,
steering, VDC system, instrument panel).

ENGAGEMENT/DISENGAGEMENT OF
“Dynamic” MODE
Engagement
Move the lever A fig. 74 upwards (next to the letter “d”) and hold in
this position for 0.5 seconds until the corresponding LED lights up
or the word “Dynamic” appears on the display (see fig. 77).
Upon release, lever A returns to the central position.
ESC and ASR:intervention thresholds that allow more enjoyable,
sportier driving whilst guaranteeing stability of the vehicle.
Steering wheel tuning:uses the sports mode function.
DST:braking standard control coordinated with ABS/ESC. Standard
control over lateral acceleration. Oversteering compensation
depending on the ESC/ASR intervention thresholds: a slight movement
on the steering wheel encourages the driver to carry out the most
appropriate manoeuvre.
Engine:prompter response + Overboost to maximise torque (for
versions/markets, where provided).In the 1.4 Turbo MultiAir versions, selecting “Dynamic” operating
mode activates the turbocharger supercharging function (overboost):
depending on the accelerator pedal position and for a limited time, the
engine management control unit allows the system to generate
maximum pressure levels inside the turbocharger and the engine
torque can reach higher values than usual.
This function is particularly useful whenever maximum performance is
required for a short time (e.g. when overtaking).
IMPORTANT During acceleration, when the “Dynamic” function is used
the steering may shudder, which is typical of a sports setting.
Disengagement
To deactivate “Dynamic” mode and return to “Natural”, repeat the
same movement of the lever within the same times. In this case, the LED
corresponding to “Natural” mode will light up and the words “Natural
on” will appear on the reconfigurable multifunction display (see fig.
78).

Maximum speed
Fuel consumption considerably increases as speed increases. Keep
your speed as even as possible, avoiding unnecessary braking and
acceleration which cause excessive fuel consumption and increased
emissions.
Acceleration
Accelerating violently severely affects consumption and emissions:
acceleration should be gradual and should not exceed the maximum
torque.
CONDITIONS OF USE
Cold starting
Short distances and frequent cold start-ups will prevent the engine from
reaching optimal running temperature. This results in a significant
increase in consumption levels (from +15 to +30% on the urban cycle)
and emissions.
Traffic and road conditions
High fuel consumption is caused by heavy traffic, for instance when
travelling in a queue with frequent use of low gears or in large towns
with many traffic lights. Winding mountain roads and rough road
surfaces also adversely affect consumption.
Stops in traffic
During prolonged stops (e.g. level crossings) switch the engine off.
TOWING TRAILERS
IMPORTANT
The vehicle must be provided with a type-approved tow hook and
adequate electrical system to tow caravans or trailers. Installation must
be carried out by a specialist.
Fit any specific and/or additional rear view mirrors as specified by the
Highway Code.
Remember that, when towing a trailer, steep hills are harder to climb,
braking distances increase and overtaking takes longer relative to
the overall weight of the trailer.
Engage a low gear when driving downhill, rather than constantly using
the brake.
The weight of the trailer reduces the load capacity of the car by the
same amount. Consider the weight at full load, including accessories
and luggage, to make sure you do not exceed the maximum towable
weight (shown in the registration document).
Respect the speed limits specific to each country for vehicles towing
trailers. In any case do not exceed 100 km/h.
