2007 Alfa Romeo 166 check engine light

20
This condition is indicated by a brief
flash of the warning light (A-fig.
10) on the check panel.
If the code has not been recognised cor-
rectly, the Alfa Romeo CODE system
warning light (A-fig. 10) stays on
together with the EOBD/fuel supply-igni-
tion system failure warning light (B-fig.
10) .
In this case, you are recommended to re-
turn the key to the STOPposition and
than back to MAR; if the inhibition per-
sists, try again possibly with the other key
provided with the car. If it is still impossible
to start the car, carry out the emergency
starting procedure described herein and
turn to an Alfa Romeo Authorized Service.
U
¢
¢IMPORTANTEvery electronic key has
its own code, which must be memorised
by the system control unit. To memorise
new keys, up to a maximum of seven,
apply solely to Alfa Romeo Authorized
Services taking with you all the keys in
your possession, the CODE card, a person-
al identity document and the car’s posses-
sion documents.
The codes of the keys
not provided during the
new memorising proce-
dure are erased from the memo-
ry. This is to ensure that any lost
or stolen keys can no longer be
used to start the car.
IMPORTANTThe Alfa Romeo CODE
warning light comes on when travelling
with the ignition key on MAR:
1) If the warning lamp lights up while
the car is moving, it means that the sys-
tem is running a self-diagnosis (e.g. due to
a voltage drop). The first time you stop y-
ou can test the system as follows: switch
the engine off by turning the ignition keytoSTOP; then turn the key back to
MAR: the warning lamp will light up and
should go out in the space of about one
second. If the warning lamp fails to go
out, leave the key at STOPfor more than
30 seconds and repeat the procedure de-
scribed previously. If the problem persists,
contact your Authorised Alfa Romeo Dealer.
2) If the warning lamp flashes it means
that the car is not protected by the immo-
biliser. Contact your Authorized Alfa
Romeo Code Dealer immediately and get
them to store the codes of all the keys in
the memory.
If after about 2 seconds
with the key in the
MAR position, the Alfa
Romeo CODE warning light turns
on again flashing at appr. half
second intervals, this means that
the code of the keys has not
been memorised, thus the car is
not protected by the Alfa Romeo
CODE system against attempted
theft. In this case, contact an Au-
thorized Alfa Romeo Service to
have the key codes memorised.

3 flashes: right rear door
4 flashes: left rear door
5 flashes: volumetric sensors
6 flashes: bonnet
7 flashes: boot
8 flashes: tampering with car starting
cables
9 flashes: tampering with battery cables
or cutting emergency key cables
10 flashes: at least three causes of alarm.WHEN THE ALARM IS
TRIGGERED
When the alarm is engaged it will sound
when:
– One of the doors, the bonnet or the
boot is opened.
– The battery is disconnected or the
electric cables are cut, or the emergency
key cables are cut.
– Intrusion into the passenger compart-
ment, e.g. window being broken (volu-
metric protection).
– Attempt to start the engine (key at
MAR).
Depending on the markets, the trigger-
ing of the alarm will activate the siren
and the hazard warning lights (for about
26 seconds). The methods of operation
and the number of cycles may vary de-
pending on the versions/markets. How-
ever a maximum number of cycles is fore-
seen. Once the alarm cycle has come to
an end the system will return to its nor-
mal monitoring state.
SWITCHING OFF THE ALARM
To switch off the alarm, press the re-
mote control button on the key. If the
alarm does not turn off due to a flat re-
mote control battery or system fault,
open the door after unlocking with the
lock key, then place the key in the igni-
tion switch and turn it to MAR.
To turn on the alarm again, turn the key
toSTOPand remove it, then press the
remote control button after leaving the
car and shutting the doors. If the alarm
does not turn on and the led on the re-
mote control gives only one brief flash
while the led on the dashboard stays on
glowing steadily for about 2 minutes, the
key battery should be replaced by a new
one of the equivalent type on sale c/o
normal retailers. To change the battery
follow the instructions given at paragraph
“Key battery change” on previous pages.
If it is not possible to switch on the
alarm with a new remote control battery,
contact Alfa Romeo Authorised Services
to have the system checked.

IMPORTANTNever leave the key in
this position when the engine is station-
ary.
–AV V: starting the engine.
IMPORTANT If the engine does not
start return the ignition key to the STOP
position and repeat the sequence.
The ignition block is fitted with a safety
device preventing it from being moved to
theAVV position when the engine is al-
ready running.If the ignition device is
tampered with (for ex-
ample during an at-
tempted break-in) have it checked
over by Alfa Romeo Authorized
Services, before travelling again.
STEERING LOCK
Engaging lock:
– move the key to the STOPposition
and remove the key lightly turning the
steering wheel to facilitate the locking ac-
tion.
Releasing the lock:
– turn the key to the MARposition
and gently rock the steering wheel in
both directions.
When leaving the vehicle
always remove the key
from the ignition to prevent any
passenger in the car from inadver-
tently activating the controls.

a car. Remember to engage the
handbrake and if the vehicle is fac-
ing uphill, first gear and if the ve-
hicle is facing downhill, reverse.
WARNING
Never remove the key
with the car on the
move. The steering wheel would
lock automatically the first time
the steering wheel is turned. This
also occurs if the car is towed.
WARNING
It is absolutely forbidden
to carry out whatever af-
ter-market operation involving
steering system or steering column
modifications (e.g.: installation of
anti-theft Device) that could badly
affect performance and safety,
cause the lapse of warranty and
also result in non-compliance of the
car with homologation require-
ments.

WARNING

66
Resetting the speed memorised
The memorised speed is automatically
reset:
– turning off the engine;
or
– moving the switch (A) to the OFF
position.
When travelling with the
cruise control engaged,
never move the gearshift lever to
neutral and do not move the au-
tomatic gearshift lever to N.
You are advised to engage the
cruise control only when the traf-
fic and road conditions permit un-
der completely safe conditions, i.e.:
straight, dry road, dual carriage-
way or motorway, flowing traffic
and smooth tarmac. Do not engage
the device in town or in heavy traf-
fic conditions.
WARNING
The Cruise Control can
only be engaged with
speed over 30 km/h and, just for
certain versions up to 180 km/h.
The device must only be engaged
in 4
th, 5thor 6thgear, depending on
the vehicle speed. On cars with
electronic automatic gearbox it
must be engaged only with the
lever at position D in the automatic
mode without then moving the
gearshift lever by hand or with 3
nd
or 4thgear engaged inthe sequen-
tial manual mode.
Moving downhill with the device
engaged, the car speed might be
slightly higher than the speed
memorised due to the change in en-
gine load.
WARNING
Should the device not be
working properly or fail
to operate, move the switch (A-fig.
78) to the OFF Position and contact
Authorized Alfa Romeo Services
after checking that the protection
fuse is intact.
The switch (A-fig. 78) may be left
constantly at ON without damag-
ing the device. You are however
advised to deactivate the device
when not in use, moving the switch
(A) to OFF, to avoid accidentally
memorising the speed.
WARNING

71
D - Rev counter
The danger zone (red) indicates exces-
sively high engine revs. Do not drive for
long periods with the pointer in this area.
With the engine at idle speed, the rev
counter may indicate a gradual or sudden
speed increase depending on the cases;
this is normal as it occurs in the normal
operation, for example when the climate
control compressor is engaged or the fan.
In particular a slow change in speed helps
preserve the battery charge.
IMPORTANT Depending on the ver-
sions/markets of the car, the rev counter
may have danger sectors (red) of differ-
ent size and with different top of scale
values.
IMPORTANT The electronic ignition
control system gradually shuts off the
flow of fuel when the engine is “over-
revving” resulting in a gradual loss of en-
gine power. Moving the ignition key to MARthe
following warning lights and displays turn
on and go out after approx. 6 seconds:
1- Light failure
2- Low brake fluid and/or handbrake
engaged
3- Front brake pad wear
4- Low engine oil level
5- Fuel reserve
6- Maximum engine coolant fluid tem-
perature
7- Mileage recorder displayAny faults are signalled by the turning
on of the corresponding warning light for
approx. 15 seconds after the end of the
check.
2) Doors and boot open warning.
With the ignition key at MAR, if a led
of the car symbol (10) lights up, the cor-
responding door or the boot has not been
shut properly.
To repeat the check, with the ignition
key in the MARposition and the engine
off, press the button (A-fig. 84).

G - The warning lights
IMPORTANT The presence of the
warning lights may vary depending on
the type of engine and trim level.
Insufficient brake fluid
and/or handbrake on
This warning light stays on for about 15
seconds, after the end of the check,
when the level of the brake fluid falls be-
low the minimum, possibly due to a leak-
age in the system and when the hand-
brake is engaged.
When the ignition key is turned to
MARthe warning light comes on but
must go out after approx. 6 seconds.
x
Air bag malfunction
When the ignition key is turned to the
MARposition the warning light will
come on and should go out as after
about. 4 seconds.
This warning light will come on perma-
nently when an anomaly affecting the Air
bag system is detected.¬
If the ¬warning light
does not turn on when
turning the ignition key to MAR or
if it stays on when travelling, this
could indicate a failure in safety re-
taining systems; under this condi-
tion air bags or pretensioners could
not trigger in the event of collision
or, in a restricted number of cases,
they could trigger accidentally.
Stop the car and contact Alfa
Romeo Authorized Services to
have the system checked immedi-
ately.
WARNING
If the warning light
comes on while driving
check if the handbrake is not en-
gaged. If the warning lights stays
on with the handbrake not engaged,
stop immediately and contact Alfa
Romeo Authorized Services.x

thorized Services.v
Low engine oil level
This warning light stays on for approx.
15 seconds, after the check, when the
engine oil level is low.
With the ignition key at MAR, pressing
the check button, the warning light turns
on but must go out after approx. 6 sec-
onds.
The oil level is checked only pressing
the check button with the engine

rupted.k
If the warning light
stays on after the
check, do not try to get
peak performance out of the en-
gine and top up the oil as soon
as possible.k
Insufficient oil pressure
This warning light should be out when
the engine is running.
When the ignition key is turned to the
MARposition the warning light comes
on and should go out as soon as the en-
gine is started. vLow battery charge
This warning light should be out when the
engine is running (a slight delay is permitted
when the engine is running at idle speed).
If the warning light comes on, Alfa
Romeo Authorized services should be con-
tacted immediately.
When the ignition key is moved to the
MARposition the warning light comes
on and should go out as soon as the en-
gine is started.w
