2017 Alfa Romeo Giulietta ECU

WHEN PARKED
Always remove the ignition key when
leaving the car.
When parking and leaving the car,
proceed as follows:
engage a gear (1st gear if facing 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.
On versions equipped with Alfa TCT
transmission, before releasing the brake
pedal, wait for letter P to be displayed.
IMPORTANTNEVERleave the car with
the gearbox in neutral (or, on versions
equipped with Alfa TCT transmission,
before placing the gear lever at P).
HANDBRAKE
To engage the handbrake, pull lever 2
fig. 62 upwards until the car is secured.
When the handbrake is engaged and the
ignition key is on MAR-ON, the
instrument panel warning light
will
switch on.
To release it, raise lever 2 slightly, hold
down button 1 and lower the lever: the
warning light
on the instrument
panel switches off.
95) 96)
IMPORTANT Carry out these
manoeuvres with the brake pedal
pressed.
IMPORTANT For cars equipped with a
front armrest, lift it up to ensure that it
does not interfere with the action of the
handbrake.
WARNING
95)Never leave children unattended in the
car. Always remove the key from the ignition
when leaving the car and take it with you.
96)The car should be braked after a few
clicks of the parking brake: if this is not so,
contact an Alfa Romeo Dealership to have it
adjusted. Always park the car safely as
indicated by the Highway Code and as
described above.
TWIN CLUTCH TRANSMISSION
(for versions/markets, where provided)
SELECTOR LEVER
The lever has the following positions:
P= Park
R= Reverse
N= Neutral
D= Drive, (automatic forward speed)
+= Sequential upshifting
−= Sequential downshifting
If the lever is used in sequential mode,
moving the latter from D to the left, the
positions towards + or – are unstable.
The lever has a button A, which must be
pressed to move the lever to P or R.
Shifting from D to "Sequential mode" and
vice versa is free.
Shifting from D to N is free.
Shifting from N to R and from R to P is
possible only with button on gear lever
pressed.
STARTING THE ENGINE
Starting is only permitted with gear lever
in position P or N (with or without brake
pedal pressed).
On starting, the system is at N or P (the
latter means neutral, but with the car’s
wheels locked mechanically).

When reverse gear is engaged an
acoustic signal is automatically activated
if there is an obstacle within the range of
operation.
The acoustic signal:
increasesas distance between the car
and the obstacle decreases;
becomes continuouswhen the
distance between the car and the
obstacle is less that 30 cm and stops
immediately if the distance increases;
is constantif the distance is unvaried;
if this situation occurs for the side
sensors, the signal will stop after about
3 seconds to avoid, for example,
indications in the event of manoeuvres
alongside walls.
OPERATION WITH A TRAILER
Parking sensor operation is automatically
turned off when the trailer electric cable
plug is fitted into the car tow hook
socket.
31)
The sensors are automatically
reactivated when the trailer's cable plug
is removed.
103) 104)
IMPORTANT NOTES
During parking manoeuvres, pay the
utmost attention to any obstacles that
could be located above or below the
sensors.
Objects set close to the car rear, under
certain circumstances are not detected and
could therefore cause damage to the car or
be damaged.
The following conditions may influence the
performance of the parking assistance
system:
reduced sensor sensitivity and a
reduction in the parking assistance
system performance could be due to the
presence on the surface of the sensor of:
ice, snow, mud, thick paint
The sensors may detect a non-existent
obstacle (echo interference) due to
mechanical interference, for example when
washing the car, in rain (strong wind), hail.
The signals sent by the sensors can also
be altered by the presence of ultrasonic
systems (e.g. pneumatic brake systems or
pneumatic drills) near the vehicle.
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 car may not be guaranteed
because the system detects obstacles that
could cause an impact with the car in the
bottom part.
IMPORTANT
31)The sensor must be free of mud, dirt,
snow or ice in order for the system to work.
Be careful not to scratch or damage the
sensors while cleaning them. Avoid using dry,
rough or hard cloths. The sensors must be
washed using clean water, with the addition
of vehicle shampoo if necessary. When using
special washing equipment such as high
pressure jets or steam cleaning, clean the
sensors very quickly keeping the jet more
than 10 cm away.
WARNING
103)Only have the bumpers repainted or
any retouches to the paintwork in the area of
the sensors carried out by an Alfa Romeo
Dealership. Incorrect paint application could
affect the operation of the parking sensors.
104)Parking and other dangerous
manoeuvres are, however, always the
driver’s responsibility. While carrying out
these manoeuvres, always make sure that
no people (especially children) or animals are
in the area concerned. The parking sensors
are an aid for the driver, but the driver must
never allow their attention to lapse during
potentially dangerous manoeuvres, even
those executed at low speeds.
