2005 Alfa Romeo 159 instrument panel

Failure warnings
System failure is indicated by the turn-
ing on of warning light
*(where pro-
vided) on the instrument panel (on cer-
tain versions together with the dedicat-
ed message on the display) (see section
“Warning lights and messages”).
IMPORTANTThe Hill Holder system
is not a parking brake. Never get out
of the car without engaging the hand-
brake, switching the engine off and en-
gaging the first gear.
ASR SYSTEM
(AntiSlip Regulation)
This system is an integral part of the VDC
system, it controls car drive and cuts in
automatically every time one or both dri-
ving wheels slip.
According to slipping conditions, two dif-
ferent control systems are activated:
❒ if slipping involves both driving
wheels, the ASR function intervenes
reducing the power transmitted by
the engine;
❒if slipping involves only one driving
wheel, the ASR system cuts in auto-
matically braking the wheel that is
slipping. This time elapsing without starting, the
system will deactivate automatically by
releasing gradually the brake force.
At releasing, the typical brake disen-
gagement noise indicating that the car
is going to move will be heard.

The performance of the
system, in terms of ac-
tive safety should not induce
the driver to take pointless
and unnecessary risks. The
style of driving must in any
case always be adapted to the
conditions of the road surface,
visibility an traffic. Road safe-
ty is always the driver’s re-
sponsibility.
WARNINGThe action of the ASR is particularly help-
ful in the following circumstances:
❒slipping of the inner wheel due to the
effect of dynamic load changes or ex-
cessive acceleration;
❒ too much power transmitted to the
wheels also in relation to the condi-
tions of the road surface;
❒ acceleration on slippery, snowy or
frozen surfaces;
❒in the case of loss of grip on a wet
surface (aquaplaning).Switching the ASR system
on/off
ASR turns on automatically when turn-
ing the instrument panel on.
When travelling the ASR can be
switched off by pressing briefly the
ASR/VDC button on the central console.
When the ASR is switched off this is
shown by the lighting up of the
ASR/VDC button led (on versions fitted
with “Reconfigurable multifunction dis-
play” symbol Vwill also be dis-
played).
If the ASR is switched off when travel-
ling, it will turn on again automatically
the next time the engine is started.
When travelling on snowy roads with
snow chains, it may be helpful to turn
the ASR off: in fact, in these conditions,
slipping of the driving wheels when mov-
ing off makes it possible to obtain bet-
ter drive.

If a failure is indicated, stop the car, turn
the engine off and then clean the sen-
sors. Make sure to be far from possible
ultrasound sources (e.g.: truck pneu-
matic brakes or pneumatic hammers).
If failure cause has been eliminated the
system will resume regular operation
and warning
tand the corresponding
warning message will turn off.
If the warning light stays on, contact Al-
fa Romeo Authorized Services to have
the system inspected, although the sys-
tem keeps on working. If the failure de-
tected does not impair system operation,
the system keeps on working and fail-
ure is stored in order to be then detect-
ed by Alfa Romeo Authorized Services
at next inspection.
GENERAL WARNINGS
When parking, take the utmost care to
obstacles that may be set above or un-
der the sensors. Objects set close to the
car front or rear part, under certain cir-
cumstances are not detected and could
therefore cause damages to the car or
be damaged.
Indications sent by the sensors can be
altered by dirt, snow or ice deposited on
the sensors or by ultrasound systems
(e.g.: truck pneumatic brakes or pneu-
matic hammers) set nearby the car.
TOWING TRAILERS
Rear sensors are reactivated automati-
cally when removing the trailer cable
plug.
FAILURE INDICATIONS
The system control unit checks every
system component each time the key is
fitted into the ignition device. Sensors
and relevant electrical connections are
then constantly monitored during sys-
tem operation.
Sensor failure is indicated by turning on
of warning light
t(where provided)
on the instrument panel (on certain ver-
sions together with the message on the
display) (see section “Warning lights
and messages”).
Rear sensors operation
is deactivated automat-
ically when the trailer
electric cable plug is fitted into
the car tow hook socket.

The car can be equipped with the
T.P.M.S. (Tyre Pressure Monitoring Sys-
tem). This system consists of a radio-fre-
quency sensor, installed on each wheel
(on the rim inside the tyre) that sends
pressure information to the control unit.IMPORTANT NOTES
Failure indications will not be stored and
therefore will not be displayed when
turning the engine off and on again. If
failure persists, the control unit will send
warning indications to the instrument
panel only after a few seconds when the
car is moving.
Tyre pressure should be checked with
tyres cold. Should it become necessary
for whatever reason to check pressure
with hot tyres, do not reduce pressure
although it is higher than the prescribed
value but repeat the check when tyres
are cold (see section “Wheels” in sec-
tion “Technical Specifications”).
TYRE PRESSURE MONITORING SYSTEM -
T.P.M.S. (where provided)
The T.P.M.S. does not
exempt the driver from
checking tyre pressure, includ-
ing the space-saver spare
wheel (where provided) at
regular intervals.
WARNING
T.P.M.S. cannot indicate sudden tyre
pressure drops (e.g.: tyre burst). In this
event, brake the car cautiously and
avoid sudden steering.
The T.P.M.S. system requires special
equipment. Consult Alfa Romeo Autho-
rized Services to know what type of ac-
cessories are compatible with the sys-
tem (wheels, wheel caps, etc.). Using
other accessories could cause system
malfunctioning. Due to inflation valve
special characteristics, use only tyre re-
pair sealants approved by Alfa Romeo;
other sealants could cause system mal-
functioning.

Since this filter physically traps particu-
lates, it shall be cleaned (reclaimed) at
regular intervals by burning carbon par-
ticles. Reclaiming procedure is controlled
automatically by the engine control unit
according to the filter conditions and the
conditions of use of the car. During re-
claiming the following phenomena could
take place: idling slight increase, fan ac-
tivation, slight smoke increase, high ex-
haust temperatures. These situations
shall not be considered as faults and they
do not affect car performance and envi-
ronment.DIESEL PARTICULATE FILTER
(DPF)
The Diesel Particulate Filter is a me-
chanical filter, integral with the exhaust
system, that physically traps particulate
present in the exhaust gases of Diesel
engines.
The diesel particular filter has been
adopted to eliminate almost totally par-
ticulates in compliance with current /
future law regulations.
During normal use of the car, the engine
control unit records a set of data (e.g.:
travel time, type of route, temperatures,
etc.) and it will then calculate how much
particulates has been trapped by the fil-
ter.Diesel particulate filter
clogged
When the Diesel particulate filter is
clogged, the instrument panel warning
light
hwill turn on (on certain ver-
sions symbol
his displayed). In
this case keep the car running until
warning light
h(or symbol
h) turns off.
