2007 Alfa Romeo 166 Owner handbook (in English)

152 TOWING TRAILERS
GENERALITIES
The vehicle can be used to tow trailers
after a suitable tow hook has been fitted.
Alfa Romeo retails a tow hook which ful-
fils the safety and legal requirements.
This tow hook should be fitted by Alfa
Romeo Authorized Services which will en-
sure a better result and avoid problems
arising which may jeopardise the body-
work warranty cover.The trailer’s braking system must be
separate from the vehicle’s hydraulic sys-
tem.
The vehicle-trailer match must conform
to the specifications of the road-traffic
laws.
Towing weight refers to the overall
weight of a fully loaded trailer including
all accessories and personal belongings.
To avoid sanctions the overall weight of a
fully loaded trailer should be checked to
ensure that it does not exceed the limits
given in the log book.
The vertical loading on the ball hook
should not in any case exceed the limits
specified in the “Technical specifications”
section.When hooking up a caravan or trailer
check that the maximum towable
weights (given in the log book) and the
maximum load permitted on the vehicle’s
tow hook (given on the label applied to
the structure of the trailer), are above or
equal to the overall weight and loading
on the towing eye.
WARNINGS AND
SUGGESTIONS
Some indications concerning driving
with a trailer are given below:
– Install the specific rear-view mirrors
as specified by law.
– Remember that when towing a trailer
steep inclines are harder to climb.
– When travelling down hill engage a
low gear rather than constantly using the
brake.
– Drive within the permitted speed lim-
its for vehicles with trailers. In any case
the maximum speed should never exceed
100 km/h.
The ABS system with
which the car is fitted
does not control the trailer brak-
ing system. Particular care is
therefore necessary on slippery
surfaces.
WARNING
Under no circumstances
should the hydraulic
braking system of the vehicle be
tampered with to control the
brakes of the trailer.
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
2.
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.

155 VEHICLE INACTIVITY
If the vehicle is to be left inactive for
long periods the following precautions
should be noted:
– House the vehicle under a cover in a
dry and possibly ventilated place.
– Engage a gear.
– Release the handbrake.
– Clean and protect the paintwork by
applying silicon wax.
– Cover the rubber windscreen wiper
blades with talcum powder and raise
them off the glass.
– Open the windows slightly.
– Cover the vehicle with a cloth or per-
forated plastic cover. Do not use compact
plastic covers which prevent the humidity
on the surface of the vehicle from evapo-
rating.
– Inflate the tyres to a pressure of 0.5
bars above normal. If possible rest the
tyres on wooden planks and periodically
check the pressure.– Switch off the alarm system (if fit-
ted) with the remote control, then deacti-
vate it with the emergency key.
– Disconnect the terminals from the
battery poles (negative pole first) and
check the battery charge. When the vehi-
cle is in storage, this check should be car-
ried out once a month. If the no-load volt-
age is less than 12.5V, recharge the bat-
tery.
REMOVING FROM STORAGE
Before using your vehicle after a long
period of inactivity the following opera-
tions should first be carried out:
– Do not dust the outside of the vehi-
cle.
– Visually check that there are no
leaks (oil, brake and clutch fluid, engine
coolant etc.).
– Replace the engine oil and filter.
– Check:
Gearbox-differential oil level
Brake-clutch fluid level
Level of engine coolant fluid.– Check the air cleaner and replace if
necessary.
– Check tyre pressure and ensure that
they are not damaged, cracked or cut. If
they are they must be replaced.
– Check the state of the drive belts in
the engine bay.
– Connect the cables of the battery af-
ter checking that the charge is adequate.
– Re-activate the alarm system, if fit-
ted, using the emergency key.
– With the gear lever in neutral start
the engine and allow the engine to run
for a few seconds whilst repeatedly
pumping the clutch pedal.

156
– Check that the various devices (head-
lights, direction indicators etc.) are working
correctly.
IMPORTANT In order to perform
these operations correctly refer to the rel-
ative subjects in the chapter “Car mainte-
nance”.
RADIO TRANSMITTERS
AND CELLULAR
TELEPHONES
Mobile phones and other radio trans-
ceiver equipment (e.g.: HAM radio sys-
tems and the like) shall not be used in-
side the car unless a separate aerial is
mounted.
IMPORTANTThe use of mobile
phones, HAM radio systems or other simi-
lar devices inside the passenger compart-
ment (without separate aerial) may
cause electronic systems equipping the
car to malfunction. This could compromise
safety in addition to constituting a poten-
tial hazard for the passengers.
In addition, transmission and reception
of these devices may be affected by the
shielding effect of the car body.
As concerns the use of mobile phones
(GSM, GPRS, UMTS) with homologa-
tion, keep strictly to the mobile phone man-
ufacturer's specifications.
INSTALLATION
OF ELECTRIC/
ELECTRONIC DEVICES
Electric/electronic devices installed after
buying the car or in aftermarket shall
bear the and marking:
Fiat Auto S.p.A. authorizes the installa-
tion of transceivers provided that installa-
tion is carried out at a specialized shop,
workmanlike performed and in compli-
ance with manufacturer's specifications.
IMPORTANTInstallation of devices
resulting in modifications of car character-
istics may cause driving license seizing by
traffic agents and also the lapse of the
warranty as concerns defects due to the
abovementioned modification or traceable
back to it directly or indirectly.
Fiat Auto S.p.A. declines all responsibili-
ty for damages caused by the installation
of non-genuine accessories or not recom-
mended by Fiat Auto S.p.A. and installed
not in compliance with the specified re-
quirements.

car, specially if the vehicle is heav-
ily laden, and wait for the wheel
to be changed out of harm of the
traffic.
If parked on a slope or rough road,
place wedges or other suitable de-
vices under the wheels to prevent
the car from rolling. Do not grease
the threads of bolts before in-
stalling them; they might slip out.
WARNING
The spare wheel is specific
to your model of car: do
not use it on another model or use
the spare wheel of other models on
your car. On cars fitted with tyres
215/55 R16 (*), 225/45 R17,
