2016 Alfa Romeo MiTo ABS

ABS SYSTEM
The car is fitted with an ABS braking system, which prevents the wheels
from locking when braking, makes the most of road grip and gives
the best control when performing emergency braking under difficult
road conditions.
The EBD system (Electronic Braking Force Distribution) completes the
system allowing the brake force to be distributed between the front and
rear wheels.
IMPORTANT To obtain the maximum efficiency of the braking system,
a bedding-in period of about 500 km is needed: during this period
it is better to avoid sharp, repeated and prolonged braking.
SYSTEM INTERVENTION
It can be detected because the brake pedal pulsates slightly and the
system gets noisier: it means that the car speed should be altered
to suit the type of road surface.
MECHANICAL BRAKE ASSIST
(emergency braking assistance)
(for versions/markets, where provided)
This system, which cannot be deactivated, recognises emergency
braking conditions (according to the brake pedal operation speed) and
provides an additional hydraulic braking pressure to support that
provided by the driver. This allows faster and more powerful operation
of the braking system.
IMPORTANT When the Mechanical Brake Assist intervenes, noises may
be heard from the system. This is normal. In any case, while braking
keep the brake pedal firmly depressed.
If the ABS system intervenes, this indicates that the
traction of the tyres on the road is nearing its limit.
Slow down to a speed compatible with the available
traction.
The ABS gets the most from the available grip, but it
cannot improve it; you should therefore take every
care when driving on slippery surfaces and not take
unnecessary risks.
When the ABS cuts in and you feel the brake pedal
pulsating, do not remove your foot, but keep the pedal
pushed down; in doing so you, will stop in the
shortest distance possible under the road conditions at the time.

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.

DRIVING MODES
Lever A is monostable type. In other words, it always remains in a
central position.
The selected driving mode is indicated by the corresponding LED
coming on in the panel and by an indication on the reconfigurable
multifunction display, as illustrated below:
❒Dynamic modefig. 75 (display image available for versions/
markets, where provided)
❒All Weather Modefig. 76
“Natural” mode
When “Natural” mode is selected, no messages or symbols are shown
on the display.
ESC and ASR systems:intervention thresholds aimed at comfort
and safety in normal grip and driving conditions.Steering wheel tuning:functions aimed at comfort in normal
conditions of use.
DST:braking standard control coordinated with ABS/ESC. Standard
control over lateral acceleration. Oversteer compensation: a slight
pulse on the steering wheel encourages the driver to carry out the most
appropriate manoeuvre.
Engine:standard response.

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).

guaranteeing the maximum safety in low grip driving conditions. It is
recommended to activate the "All Weather" mode when fitting snow
chains.
Steering wheel tuning:maximum comfort.
DST:higher braking 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:standard response.Disengagement
To deactivate “All Weather” mode and return to “Natural”, carry out
the same procedure described for “Dynamic” mode, but move lever A
fig. 74 to “a”.
IMPORTANT
❒It is not possible to switch directly from “Dynamic” mode to “All
Weather” mode and vice versa. You must always first go back
to “Natural” mode and then select the other mode.
❒The driving mode engaged before the engine stops is maintained
when it is next started.
❒In the event of system failure or a fault with lever A fig. 74, no
driving modes can be selected. The display will show a warning
message.

JUMP STARTING
When jump starting, never connect the negative lead (–) of the
auxiliary battery to the negative pole A fig. 83 of the car battery, but
rather to an engine/gearbox earth point.
Before opening the bonnet, make sure the engine is off and
the ignition key is in the STOP position. Follow the
indications on the plate underneath the bonnet fig. 84. It is
advisable to extract the key when there are other people in the car.
Leave the car only after having removed the ignition key or having
turned it to STOP. During refuelling, make sure that the engine is off
and that the ignition key is in the STOP position.
DYNAMIC SUSPENSION
(active shock absorber system)
(for versions/markets, where provided)
This system interacts with the “Alfa DNA” system (see paragraph “Alfa
DNA”).
The “Alfa DNA” system lever allows you to choose three different
driving settings depending on the route type and on the road surface:
❒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).

In “Natural” and “All Weather” operating mode, the active shock
absorbers adjust the car suspension to suit the route type and
the driving stresses, thus considerably improving driving comfort in
particular on rough terrain.
The "Dynamic" operating mode produces a sports driving setting
characterised by more responsive acceleration and greater effort on
the steering wheel to give a sporty feeling. The shock absorber
damping action is also adjusted and divided, to guarantee higher
precision and reactivity of the car, while maintaining a good comfort
level.
The car is more precise when entering bends and quicker in changing
direction.EOBD SYSTEM
(European On Board Diagnosis)
(for versions/markets, where provided)
The aim of the EOBD system (European On Board Diagnosis) is to:
❒monitor the system efficiency;
❒indicate an increase in emissions;
❒indicate the need to replace damaged components.
The car also has a diagnostic connector that can be interfaced with
appropriate tools, which makes it possible to read the error codes
stored in the electronic control units together with a series of specific
parameters for engine operation and diagnosis. This check can also be
carried out by the traffic police.
IMPORTANT After eliminating a fault, to check the system completely,
Alfa Romeo Authorised Services are obliged to run tests and, if
necessary, road tests which may also call for a long journey.

ELECTRIC POWER STEERING
This only operates with the key turned to MAR-ON and the engine
started. Power steering allows the force required at the steering wheel
to be adapted to driving conditions.
The different power assistance modes can be selected via the "d,n,a"
positions of the “Alfa DNA System” lever (see “Alfa DNA System”
paragraph).
It is absolutely forbidden to carry out any after-market
operation involving steering system or steering column
modifications (e.g.: installation of anti-theft device)
that could badly affect performance and safety, invalidate the
warranty and also result in non-compliance of the car with
type-approval requirements.
Before performing any maintenance operations,
always turn off the engine and remove the key from
the ignition to lock the steering column, especially
when the car’s wheels are not touching the ground.
