engine Alfa Romeo Giulietta 2016 Repair Manual

POSITIONS OF THE
LEVER
Park (P)
Position P corresponds to the neutral
position of the transmission and locks
drive wheels mechanically.
It should only be engaged with the car
stationary and the handbrake should be
applied, if necessary.
With the ignition key at MAR-ON or with
engine running, or when the engine
switches off, if the gear lever is not
correctly positioned in P, letter P starts
flashing on the gear lever trim.
In this case, move the lever correctly to
position P.
21)
The ignition key can be removed only
when the lever is in position P. Moving
the lever from P to D must be
performed only when the car is
stationary and the engine at idling
speed.
Shifting from P to any other position of
the selector lever, with ignition key in
MAR-ON position, must be made
pressing the brake pedal and using the
button on the gear lever (see paragraph
"Selector lever").
If the battery is flat, to release the lever
you need to remove the gaiter and
operate the lever A fig. 132.IMPORTANT NEVER leave the car
before having positioned the selector
lever in P.
Reverse (R)
The engine cannot be started with the
lever in position R.
Shifting from R to N or D is free, while
shifting from R to P can be made by the
button on the gear lever, with engine
at idling speed.
22)
Neutral (N)
It corresponds to neutral for a standard
manual gearbox. The engine can be
started with the lever in position N.
Engage N in case of prolonged stops.
To move the lever from position N,
release the accelerator and make sure
the engine is stable at idling speed.Shifting from N to D is free, while
shifting from N to R or P can only be
made by the button on the gear lever.
Drive (D) - Automatic
forward gear
It is the lever position in standard
running conditions.
Shifting from D to N is free, while
shifting from D to R or P can only be
made by the button on the gear lever.
Sequential mode (+ / –)
Shifting the lever from position D on
side in stable position, the transmission
is used in sequential mode.
Shifting the lever in unstable position (+
or −) gears are changed.
Important information
IMPORTANT All movements of the gear
lever must be performed with car
stationary and engine idling only.
The drive wheels are mechanically
locked in position P.
Shifting from P to R is possible with
brake pedal pressed and button on
gear lever pressed.
Shifting from R to N and from N to D is
free.

STARTING AND DRIVING

Shifting from D to "Sequential mode" is
free.
Shifting from "Sequential mode" to D is
free.
Shifting from D to N is free.
Shifting from N to R is possible only
with button on gear lever pressed.
Shifting 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).
Start&Stop system
With car at a standstill and Start&Stop
system activated, the engine switches
off if the gear lever is in a position
other than R.
The Start&Stop system does not
operate when the gear lever is in R, for
making parking manoeuvres easier.
In the event of stops uphill, the engine
switching off is disabled to activate
the "Hill Holder" function (works only
with running engine).The engine restarts automatically if:
❒the brake pedal is released (and the
lever is not at N or P)
❒the lever is shifted to an unstable
position: +, − or R
❒the lever is shifted from D to the left
in "Sequential mode"
❒by the "+" or "–" paddles on the
steering wheel (for versions/markets,
where provided)
During the engine stop and start
sequence, the system passes through
the automatic engagement of neutral:
the display shows N.
IMPORTANT In some conditions (for
example with small gradients and brake
pedal not fully depressed), engine
switching off is not deactivated. In this
case, fully depress the brake pedal
to make the "Hill Holder" function
available and restart the engine, using
the gear lever or the paddles on the
steering wheel (for versions/markets,
where provided) as described
previously.ENGINE SWITCHING OFF
Engine can be switched off in any
position of the gear lever.
Versions with
Start&Stop system
To switch the engine off, you need to
stop the car by pressing the brake
pedal properly; if the pressure is not
enough, the engine will not be switched
off.
This feature can be exploited so that
the engine does not switch off in
particular traffic conditions.
Ignition key removal
The ignition key can be removed only if
the gear lever is in position P:
❒if the engine is switched off with the
gear lever in position P: the ignition
key can be removed within 30
seconds;
❒if the engine is switched off with the
gear lever in a position other than P:
the P letter on the display and on
the gear lever trim flashes for 5
seconds and an acoustic signal will
be emitted at the same time. Move
the lever to P within 5 seconds; then
it will be possible to remove the
ignition key for about 30 seconds.
153

In both cases, if the described
conditions and times are not respected,
the ignition key will be automatically
locked.
To remove the key, turn it to MAR-ON
and then to STOP.
IMPORTANT If the battery is flat and the
ignition key is engaged, the latter is
locked in position. To remove the key
manually, pull up the handbrake and
insert the screwdriver supplied in the
hole under the dashboard fig. 133
pressing slightly, until the key is
removed.MOVING THE CAR
To move the car, from P press the
brake pedal and, using the button on
the gear lever, move the lever to the
desired position (D, R or "Sequential
mode").
The display will show the gear
engaged.
When the brake pedal is released, the
car starts moving forwards or
backwards, as soon as the manoeuvre
is activated ("creeping" effect). The
accelerator should not be pressed in
this case.
IMPORTANT The inconsistency
between the speed actually engaged
(shown on the display) and the position
of the gear lever is indicated by the
letter corresponding to the position of
the lever flashing on the trim (also
accompanied by an acoustic signal).
This condition should not be interpreted
as an operational fault, but simply as a
request by the system to repeat the
manoeuvre.
IMPORTANT With engine running and
car stationary, in "Sequential mode",
the request for engaging 2
ndgear is not
accepted by the system (whether the
brake pedal is pressed or not).If, with 1
stgear or reverse (R) engaged,
the following conditions occur:
❒road slope over 5%;
❒clutch overheated;
❒engine torque constant for a given
period (e.g. if the car hits the
pavement or is parked downhill/
uphill);
car movement is achieved by pressing
the accelerator pedal.
IMPORTANT With handbrake released
and brake pedal released, engine at
idling speed and gear lever in position
D, R or sequential, pay the utmost care
because the car can move even
without the operation of the accelerator
pedal. This condition can be used
with the car on a level surface during
tight parking manoeuvres using the
brake pedal only.
AUTOMATIC DRIVING
MODE
D can be selected from sequential
operation in any driving conditions.
In automatic driving mode, the best
ratio is selected by the electronic
transmission control unit depending on
speed, engine load (accelerator pedal
position) and gradient of the road.
133A0K0254
154
STARTING AND DRIVING

“Kick-Down” function
To resume speed quickly, when the
accelerator pedal is pressed fully, the
transmission control system downshifts
("Kick-down" function).
IMPORTANT When driving on roads
with poor grip conditions (snow, ice,
etc.) avoid activating the kick-down
function.
Integration with "Alfa
DNA" system
Operating the “Alfa DNA” system fig.
134, three different driving modes can
be selected:
❒“Dynamic”: gear changes at higher
engine speeds. It enhances sporty
driving;❒“Natural”: gear changes at low
engine speeds. It enhances comfort
and reduces consumption;
❒“All Weather”: driving programme on
roads with poor grip (e.g. snow, ice,
mud, etc.).
Gearshifting suggestion
With the transmission in automatic
mode (selector lever in position D),
when gearshifting is required by the
paddles on the steering wheel (for
versions/markets, where provided), the
system shifts to "Sequential mode",
with relevant displaying of the gear
engaged, for about 5 second.
When this time has elapsed, if the
paddles are not operated anymore, the
system goes back to the automatic
mode (D), with following displaying.
SEQUENTIAL DRIVING
MODE
In sequential driving mode, the
transmission works like a manual
gearbox.Gearshifting through
gear lever
Move the lever sideways (to the left)
from position D to the sequential
position:
❒lever towards "+": engage higher
gear;
❒lever towards "−": engage lower gear.
The lever correct position in "Sequential
mode" is signalled when the symbols
"+" and "−" switch on and the symbol D
switches off on the display (the gear
engaged only is shown on the display).
Gearshifting through
steering wheel paddles
(for versions/markets, where provided)
On some versions, the steering wheel
paddles can be used to change gear
fig. 135.
106)
134A0K0612
135A0K0266
155

To use the paddles on the steering
wheel, the gear lever must be in
"Sequential mode" or in D:
❒steering wheel paddle "+" (pulling
paddle towards driver fig. 136):
engage higher gear;
❒steering wheel paddle "-" (pulling
paddle towards driver fig. 136):
engage lower gear.The engagement of a lower or higher
gear is only permitted if the engine revs
allow it.
If the car is stopped with a higher gear
than 1
stengaged, the transmission
will automatically engage 1stgear.
"Launch Control"
Function
The "Launch Control" strategy permits
high-performance starting.
With the car stationary, proceed as
follows to activate this function:
❒operate the “Alfa DNA” system and
activate the "Dynamic" driving mode;
❒depress the brake pedal with your left
foot and, simultaneously, fully
depress the accelerator pedal with
your right foot;
❒release the brake pedal: in this way a
more "lively" start is achieved.When the brake pedal is released, the
car will start with maximum
acceleration. Despite the "Sequential
mode", the car will autonomously shift
the gear to guarantee max.
acceleration, once the correct shifting
speed has been reached.
108)
To abandon the strategy, simply
interrupt the above sequence
of operations or release the accelerator
pedal.
ACOUSTIC SIGNAL
For safety reasons, an acoustic signal is
heard when:
❒the driver's side door is opened with
engine running and the gear lever is
in a position other than P;
❒engine is switched off with gear lever
in a position other than P.
With the car stationary, the engine
started and (1st), (D) or (R) gear
engaged, the system activates the
acoustic signal and automatically
places the transmission in neutral (N)
when:
❒the accelerator and/or brake pedals
are not pressed for at least 3 minutes
with creeping deactivated (for
example with handbrake engaged);
136A0K0269
137A0K0271
156
STARTING AND DRIVING
❒shift gear using the gear lever or the
steering wheel paddle "−" (pulling
the paddle towards the driver as
previously described): rpm are thus
increased from 2750 to 4500; (1.4
Petrol versions) and from 1700 to
2700 (2.0 JTD
Mversions);

❒the brake pedal is pressed for longer
than 10 minutes;
❒the driver's door is opened with
creeping deactivated (for example
with handbrake engaged) without
pressing brake and/or accelerator
pedals;
❒a fault has been detected in the
transmission.
IMPORTANT Shifting to neutral (N) -
operated by the system - involves
a situation of inconsistency between
gear lever position and gear engaged.
The manoeuvre is accompanied by
an acoustic inconsistency signal. This
acoustic signal continues until the gear
lever is placed in P or N, to restore
the correct transmission operation
conditions.
PARKING THE CAR
To park safely, with the brake pedal
pressed, P must be engaged and, in
case of parking uphills/downhills, the
handbrake must be engaged.
Before releasing the brake pedal, wait
until P appears on the display.
IMPORTANT NEVER leave the car
before having positioned the lever in P.TOWING THE CAR
Make sure that the transmission is in
neutral (N), checking that the car moves
when pushed, and proceed in the
same way as for towing a normal car
with a manual gearbox.
IMPORTANT If the transmission cannot
be put in neutral (N), do not tow the
car and contact an Alfa Romeo
Dealership. Should the lever be in P,
release it before towing (see paragraph
"Positions of the lever").
IMPORTANT
INFORMATION
With car stationary and gear engaged,
always keep the brake pedal pressed
until you decide to set off, then release
the brake and accelerate gradually.
During prolonged stops with the engine
running, it is advisable to keep the
transmission in neutral (N).
To protect the clutch, never use the
accelerator to keep the car stationary
(for example when stopped uphills/
downhills): clutch overheating could
damage it. Use the brake pedal instead
or the handbrake and only press the
accelerator pedal when you wish to set
off.If reverse (R) is engaged, only engage
the 1stgear (or vice versa) when the car
is completely stopped.
Although it is highly inadvisable, if you
are driving downhill and, for unexpected
reasons, you let the car move forward
with the transmission in neutral (N),
when there is a request to engage
a gear, depending on the speed of the
car, the system will automatically
engage the best gear for the correct
transmission of drive torque to the
wheels.
107)
IMPORTANT
21) If the car is on a gradient, always
pull the handbrake BEFORE
placing the gear lever in P.
22) Engage reverse only with the car
stationary, engine at idling speed
and accelerator fully released.
157

DRIVING STYLE
Starting
Do not warm up the engine at low or
high revs when the car is stationary;
this causes the engine to warm up
more slowly, thereby increasing fuel
consumption and emissions. It is
therefore advisable to move off
immediately, slowly, avoiding high
speeds: in this way the engine will
warm up more quickly.
Unnecessary actions
Avoid accelerating when stopped at
traffic lights or before switching off the
engine. The latter action, as well as
double-declutching, is unnecessary and
causes increased fuel consumption
and pollution.
Gear selection
Use a high gear when traffic and road
conditions allow it. Using a low gear for
faster acceleration will increase fuel
consumption. In the same way
improper use of a high gear increases
consumption, emissions and engine
wear.Maximum speed
Fuel consumption considerably
increases as speed increases. Maintain
a constant speed, avoiding
unnecessary braking and acceleration,
which cost in terms of both fuel
consumption and 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 hold-ups (e.g. level
crossings) switch off the engine.
159

STORING THE CAR
If the car is to be left inactive for longer
than a month, the following precautions
should be noted:
❒park the car in covered, dry and if
possible well-ventilated premises and
slightly open the windows;
❒check that the handbrake is not
engaged;
❒disconnect the negative battery
terminal and check the battery
charge. Repeat this check once
every three months during storage;
❒if the battery is not disconnected
from the electrical system, checks its
state of charge every thirty days;
❒clean and protect the painted parts
using protective wax;
❒clean and protect the shiny metal
parts using special compounds
available commercially;
❒sprinkle talcum powder on the
windscreen and rear window wiper
rubber blades and lift them off the
glasses;
❒slightly open the windows;❒cover the car with a cloth or
perforated plastic sheet. Do not use
compact plastic sheets which do
not allow humidity to evaporate from
the surface of the car.
❒inflate tyres to +0.5 bar above the
standard prescribed pressure and
check it periodically;
❒do not drain the engine cooling
system;
❒Any time the car is left inactive for
two weeks or more, operate the
air conditioning system with engine
idling for at least 5 minutes, setting
external air and with fan at maximum
speed. This operation will ensure a
suitable lubrication to minimise
possibility of damage to the
compressor when the system is
operated again.
IMPORTANT After turning the ignition
key to STOP, wait at least 1 minute
before disconnecting the electrical
supply to the battery.

STARTING THE
ENGINE
Contact the Alfa Romeo Dealership
immediately if the warning light
stays on constantly on the
instrument panel.
JUMP STARTING
If the battery is flat, start the engine
using an auxiliary battery with the same
capacity or a little higher than the flat
one.
24) 25)112)
Proceed as follows to start the car:
❒connect the positive terminal (+) fig.
138 of the auxiliary battery only to
the point indicated on the car battery
(writing OK) and nowhere else;
❒with a second lead, connect the
negative terminal(−)oftheauxiliary
battery to an earthing point
on
the engine or the gearbox/
transmission of the car to be started;
❒start the engine; when the engine has
been started, remove the leads
reversing the order above.
For versions with Start&Stop system, in
case of starting by auxiliary battery,
refer to the paragraph “Start&Stop
system” in the chapter “Getting to know
your car”.If after a few attempts the engine does
not start, contact the Alfa Romeo
Dealership.
BUMP STARTING
Never jump start the engine by pushing,
towing or coasting downhill.
IMPORTANT
24) Do not connect the negative
terminals of the two batteries
directly! If the auxiliary battery is
installed on another car, prevent
accidental contact between
metallic parts of the two cars.
25) Never use a fast battery charger
to start the engine as this could
damage the electronic systems
and the ignition and engine fuel
supply control units.
WARNING
112) This procedure must be
performed by qualified personnel
as incorrect actions may cause
high-intensity electrical discharge.
Furthermore, battery fluid is
poisonous and corrosive: avoid
contact with skin and eyes. Keep
naked flames away from the
battery. No smoking. Do not cause
sparks.
