2006 Alfa Romeo 166 spare wheel

92
The temperature near
the heater should never
exceed 120°C (e.g. dur-
ing body painting operations in
the workshop oven). Higher tem-
perature could damage the elec-
tronic control unit components.
For maintenance and repairs con-
tact only Authorized Alfa Romeo
Services and only use original
spare parts.
The burner exhaust gas
is released in the centre
floor area: therefore never park
the car with the engine running
over inflammable surfaces, fire
hazard!
WARNING
IMPORTANT When the heater is
working with the vehicle stationery and
the engine running, standing outside the
car near the rear wheel arch a low noise
caused by normal operation of the heater
can be heard.MAINTENANCE
Have the additional heater checked at
regular intervals by Authorized Alfa
Romeo Services. This will ensure safe,
cost-effective working of the heater and
also long life.

POWER STEERING
The hydraulic power steering is only ac-
tive when the engine is running. If the en-
gine is switched off greater effort will be
required to turn the wheel.
As the steering system is a mechanical
organ which is closely tied to driving
safety, the vehicle should be stopped and
Alfa Romeo Authorized Services contacted
if an anomaly is detected.
IMPORTANT Keep the steering wheel
turned at the end of its stroke, in both di-
rections, only for the strictly indispensable
time.
WINDOWS
Do not apply stickers or similar adhe-
sives to the windows as these may dis-
tract the driver and block his vision. The VDC system turns on automatically
when the car is started and cannot be
switched off. It is however possible to cut
off operation of the ASR system pressing
the corresponding button on the centre
console.
ASR FUNCTION (ANTISLIP
REGULATION): GENERAL
The ASR system integrates the VDC sys-
tem controlling the vehicle drive and com-
ing into operation automatically each
time one or both driving wheels skid.When changing the
wiper blades follow the
instructions contained in
the package which is available as
a spare part and read the indica-
tions given in the “Car mainte-
nance “ chapter of this booklet.
WINDSCREEN WIPER BLADES
The windscreen wiper blades should be
checked periodically. Dirty or worn blades
greatly reduce visibility. The windscreen
and windows should be cleaned regularly
and grease, dirt and tar removed. In this
way the life of blades will be extended
considerably.The VDC system helps
the driver to keep control
of the car in the event of loss of
tyre grip.
The forces induced by the VDC sys-
tem to control the lack of stability
of the car always and anyway de-
pend on the grip between the tyre
and the road surface.
WARNING
Before operating the windscreen wipers,
remove snow or ice from the windscreen
and check that the wiper blade is not
frozen to the windscreen. Use an an-
tifreeze product if necessary.
Do not operate the windscreen wipers
on dry glass.

WHEELS
The wheels (rims and tyres) installed in
the factory are those which are most suit-
ed to the characteristics of the vehicle
and guarantee the greatest degree of
safety and comfort under all normal dri-
ving conditions.
Before replacing the rims or tyres in-
stalled on your vehicle consult the table
indicating the permitted types given in
the “Technical specifications” chapter of
this manual or contact Alfa Romeo Autho-
rized Services.
The original rim-tyre match should be
followed when changing tyres.IMPORTANTS (when using a s-
pare wheel different from the
other wheels of the car)
– The spare wheel should only be used in
an emergency.
– Use of the spare wheel should be kept
to a minimum. Do not drive at speeds of
over 80 km/h.
– The car will handle differently when the
spare wheel is fitted. Avoid sudden acceler-
ation or braking, sharp corners and fast
bends.
– Check at regular intervals that spare
wheel pressure is equal to 2.7 bar (2.7
kg/cm
2).
SPARE WHEEL
Cars fitted with steel rims and tyres
215/55 R16 (*) have spare wheel iden-
tical with the standard wheels. Cars fitted
with aluminium alloy rims and tyres
215/55 R16 (*), 225/45 R17 and
235/40 R18 have the spare wheel with
steel rim and tyre 215/55 R16 (*).
(*) For versions/markets where applic-
able tyres 205/55 R16.
The jack should only be
used when changing a
wheel; Do not work under the ve-
hicle when this is only supported
using the jack.
WARNING
While the specified di-
mensions remain un-
changed, for travelling safety and
correct operation of the VDC, ASR
and ABS systems the tyres must
absolutely be of the same brand
and type on all wheels, in perfect
conditions and above all of the
specified type and brand.
WARNING
On cars fitted with tyres
215/55 R16 (*), 225/45
R17, 235/40 R18 and spare wheel
with tyre 215/55 R16 (*), since
the spare wheel is different from
the standard wheels, observe the
instructions for use given below.
(*) For versions/markets where ap-
plicable tyres 205/55 R16.
WARNING

144
– Two or more spare wheels should never
be used together. Have the wheel changed
repaired and refitted as soon as possible.
Rims
The bolts should be tightened to a
torque of 86 Nm (8.8 kgm).
Tyres
The tyres installed on the vehicle are of
the tubeless type and do not have an in-
ner tube. To obtain the greatest degree of
comfort, safety and length of life of the
tyres, the following recommendations
should be observed.
– With new tyres do not drive at full
speed until the first 100 km have been
reached.
– Before entering a tight bend, even if
the vehicle permits it, reduce speed.
– Avoid sharp acceleration and unneces-
sary braking.
– Do not travel for long periods at sus-
tained high speed especially on rough
roads.– Have the wheels balanced and the
front and rear axles set correctly.
– Avoid hitting the side walls of the
tyres, for example when parking.
– Never tamper with the valve on the
tyre.
– Do not insert anything between the
rim and the tyre.
– If the rim is bent, have it replaced.
– In the event of an abnormal drop in
the tyre pressure replace the wheel and
have it checked.
– When balancing the wheels use the
counterweights which are specifically de-
signed for tubeless tyres. To balance light
alloy rims only Alfa Romeo original
weights should be used.
– The tyre pressure, including that of
the spare wheel must reflect the indica-
tions given in the “Technical specifica-
tions” of this manual.
– Have the tyres checked periodically to
ensure that they are not damaged in any
way.– Second-hand tyres of unknown origin
or over 6 years old must only be used in
emergencies and with great care.
– Inner tubes must not be fitted to
tubeless tyres.
– Avoid parking the vehicle on the edge
of a step or other irregularities in the road
surface.
– Have the tyre tread checked periodi-
cally and replace when the legal mini-
mum is reached.
IMPORTANT Some types of tyres are
fitted with wear indicators. As soon as
these wear indicators appear on the tyre
tread, the tyres must be replaced.
Periodically check that the tyres are not
showing signs of irregular tread wear. If
they are, contact Alfa Romeo Authorized
Services who will eliminate the cause of
irregular wear.
Tread wear increases the danger of
aquaplaning on wet surfaces.

145
To ensure uniform wear between the
tyres on the front axle and those on the
rear axle, the tyres should be switched
around every 10,000 - 15,000 km keep-
ing the tyres on the same side of the ve-
hicle to avoid inverting the direction of ro-
tation (fig. 1).Note for one way tyres: There
are arrows on the side of one-way tyres
indicating the direction of rotation. When
a wheel is changed (for example after a
puncture, the direction of the arrow on
the spare wheel might not coincide with
the direction of rotation of the wheel to
be changed. Even in these conditions the
tyre is still safe but you are advised to
have the tyre repaired and refitted as
soon as possible, because top perfor-
mance is obtained when all the wheels
turn in the direction of the arrow.Tyre pressure and wear
The correct tyre pressure will not only
ensure that your tyres last longer but will
also make your vehicle safer as they have
a direct influence over road holding.
The pressure of each tyre, including that
of the spare tyre should be checked regu-
larly and always before a long journey.
The tyres should be checked when cold
using a pressure gauge and inflated to
the pressure given in the chapter “Techni-
cal specifications”.
Incorrect tyre pressure causes tyre wear
(fig. 2):
Do not cross the tyres
over.

158IN THE EVENT
OF A PUNCTURE
Wheel changing and cor-
rect use of the jack and
spare wheel call for some precau-
tions as mentioned below.
Signal the presence of the station-
ary vehicle according to current
regulations: hazard warning lights,
reflecting triangle, etc.
Any passengers should leave the
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,
235/40 R18 and spare wheel with
tyre 215/55 R16 (*), since the
spare wheel is different from the
standard wheels, observe the in-
structions for use given below:
