2007 Alfa Romeo 166 warning light

151
Use an auxiliary battery to start the ve-
hicle in an emergency.
If the engine is not “running smoothly”
when the vehicle is travelling, reduce the
request for performance to a minimum
and contact Alfa Romeo Authorized Ser-
vices as soon as possible.
When the fuel reserve warning light
comes on fill up as soon as possible. A
low fuel level may cause an irregular sup-
ply to the engine with inevitable increase
of the exhaust gas temperature.
When travelling downhill for long
stretches slightly rev the engine every
now and again. This action will extend
the life of the catalyzer.
Never run the engine, even as a test,
with one or more spark plugs disconnect-
ed.
During normal operation
the catalytic converter
reaches high temperatures. Do not
therefore park the vehicle over in-
flammable materials (grass, dry
leaves, pine needles etc.): fire haz-
ard. Do not install other heat
shields and do not remove the ex-
isting ones on the catalyst and on
the exhaust pipe.
Do not spray anything on the cat-
alyst, lambda sensor and exhaust
pipe.
WARNING
The failure to follow
these rules may cause a
fire hazard.
WARNING

153
Apart from the electrical branches taken
off for the obligatory signalling devices,
the vehicle’s electrical system can only be
connected to the supply cable for an elec-
tric brake and to the cable for internal
light, though not above 15W, in the trailer.
The electric brake must be directly sup-
plied by the battery through a cable with
a cross-section of over 2.5 mm

INSTALLING TOW HOOK
(fig. 3)
The chart shows the attachment points
for fixing the tow hook to the body.
These points must not be changed irre-
spective of the shape and size of the
hook. For mechanical connection the fol-
lowing must be used:
– “ISO 50” 2nd category ball hook
(CUNA Table NC 138-40)
– 2nd category ball eyelet model “CU-
NA 502” (CUNA Table NC 438-40)
The tow hook structure must be fas-
tened in the points shown by the symbol
Øwith a total of 12 M10 screws.
The inner plate (1) should be at least 4
mm thick.
The side plates (2) should be at least 5
mm thick.
The fastening points (3) must be fitted
with a spacer with a 25 mm diameter
and 6 mm thickness.IMPORTANTIt is compulsory to fas-
ten a label of suitable size and material
(clearly visible) at the height of the hook
ball with the wording:
MAX. LOAD ON BALL 60 kg.
ELECTRICAL CONNECTIONS
The attachment for the trailer wiring
connections are to be applied to the tow
hook support in the most suitable posi-
tion.
For the electrical connections a 13 pole,
12V connection must be used.
For vehicle-trailer electrical connections
contact Authorized Alfa Romeo Services.Do not connect any
trailer services (fan,
fridge, etc.) to the vehi-
cle’s electrical system.
After assembly, the fas-
tening screw holes
should be sealed to prevent the in-
filtration of exhaust gas.
WARNING
