WARNING
46)The presence of the TPMS does not
permit the driver to neglect regular checks
of the tyre pressure, including for the spare
wheel.
47)Tyre pressure must be checked with
tyres rested and cold. Should it become
necessary for whatever reason to check
pressure with warm tyres, do not reduce
pressure even though it is higher than the
prescribed value. Repeat the check when
the tyres are cold.
48)Should one or more wheels be fitted
without sensors, the system will no longer
be available and, in addition to the TPMS
warning light flashing for less than one
minute before becoming constant, a
warning message will be shown on the
display, until four wheels with sensors are
fitted again.49)The TPMS cannot warn of sudden
decreases in tyre pressure (for example
when a tyre bursts). In this case, stop the
car, braking with caution and avoiding
abrupt steering.
50)Replacing standard tyres with winter
tyres (and vice versa) requires TPMS
adjustment that must only be performed by
a dedicated Alfa Romeo Dealership.
51)Changes in outside temperature may
cause tyre pressures to vary. The TPMS
system may temporarily indicate insufficient
pressure. In this case, check the tyre
pressure when cold and, if necessary,
restore the inflation values.52)When a tyre is removed, it is advisable
to replace the rubber valve seal as well:
contact a dedicated Alfa Romeo
Dealership. Tyre and/or rim fitting/removal
operations require specific precautions; to
avoid damaging or fitting the sensors
incorrectly, tyre and/or rim fitting/removal
operations should only be carried out by
specialised staff. Contact a dedicated Alfa
Romeo Dealership.
53)Intense radio-frequency interference
may prevent the correct operation of the
TPMS. This condition will be indicated by a
message on the display. The message will
disappear automatically as soon as the
radio-frequency interference ceases to
affect the system.

Traffic and road conditions
Rather high consumption levels are
linked to situations with heavy traffic, for
instance when travelling in queues with
frequent use of the lower gears or in
cities with many traffic lights.
Stops in traffic
During prolonged hold-ups (e.g. level
crossings) the engine should be
switched off.SNOW TYRES
Use snow tyres of the same size as the
normal tyres provided with the car: the
dedicated Alfa Romeo Dealership will
be able to advise you on the most
appropriate tyre to use.
Only use these tyres in the event of ice
or snow on the roads. In these
conditions it is recommended to select
the "All Weather" mode of the Alfa DNA
system.
For the type of tyre to be used, inflation
pressures and the specifications of
snow tyres, follow the instructions given
in the "Wheels" paragraph in the
"Technical specifications" chapter.
90)
The performance of these tyres on
low-grip surfaces are reduced
considerably when the tread depth is
below 4 mm. They should be replaced
in this case.
Due to the specific characteristics of
snow tyres, in normal weather
conditions and dry asphalt or on long
motorway journeys, the performance of
these tyres is lower than that of
standard tyres. Their usage should
therefore be restricted in accordance
with their type approval.
IMPORTANT When using snow tyres
with a maximum speed index below the
one that can be reached by the car
(increased by 5%), place a notice in the
passenger compartment, plainly in view,
which states the maximum speedallowed by the snow tyres (as per EC
Directive).
All four tyres should be the same brand
to ensure greater safety when driving
and braking as well as making the car
more responsive. It is inadvisable to
change the rotation direction of tyres.
Refer to the "Raising the car" section in
the "In an emergency" chapter for
further details on how to raise the car
correctly.
WARNING
90)The maximum speed for snow tyres
marked “Q” is 160 km/h, while it is
190 km/h for “T” tyres and 210 km/h for
"H" tyres. The highway code speed limits
must however always be complied with.

STARTING AND DRIVING

SNOW CHAINS
Reduced size snow chains with a
maximum projection of 7 mm beyond
the tyre profile can be fitted only on
235/40 R18 rear tyres.
The use of snow chains should be in
compliance with local regulations. Snow
chains can be fitted on the tyres of the
rear wheels (drive wheels) only. 19" rear
tyres cannot be fitted with chains.
Check the tension of the snow chains
after the first few metres have been
driven.
11)
IMPORTANT Snow chains cannot be
fitted to the space-saver wheel (for
versions/markets, where provided).
IMPORTANT
11)Keep your speed down when snow
chains are fitted; do not exceed 50 km/h
(or the equivalent in miles). Avoid potholes,
do not drive over steps or sidewalks and do
not drive long distances over roads without
snow, to avoid damaging both your vehicle
and the road surface.
CAR INACTIVITY
If the vehicle is to be left inactive for
longer than a month, observe the
following precautions:
park the car in covered, dry and if
possible well-ventilated premises and
slightly open the windows;
check that the handbrake is not
engaged;
disconnect the negative battery
terminal and check the battery charge.
Repeat this check once every three
months during storage. For optimum
preservation of the battery charge, it is
advisable to use the charge-holder (for
versions/markets, where provided, or
alternatively, available from
Lineaccessori). For more details on its
operation, refer to the attached
Supplement;
if the battery is not disconnected
from the electrical system, checks its
state of charge every thirty days;
clean and protect the painted parts
using protective wax;
sprinkle talcum powder on the
rubber blade of the windscreen wiper
and lift it off the glass (for the correct
lifting procedure, refer to the
"Windscreen wiper" paragraph in the
"Maintenance and care" chapter);
cover the car with a cloth or
perforated plastic sheet. Do not use
sheets of non-perforated plastic as theydo not allow moisture on the car body
to evaporate;
inflate tyres to +0.5 bar above the
standard prescribed pressure and
check it periodically;
do not drain the engine cooling
system;
every time the car is left inactive for
two weeks or longer, run the air
conditioning system for about 5
minutes, set to outside air and with fan
set to maximum, with the engine idling;
this operation will ensure adequate
lubrication to minimise the possibility of
damage to the compressor when the
system is put back into operation;
ensure that the air intake directly in
front of the windscreen is not
obstructed by leaves or other foreign
bodies; any leaves in the air intake
could reduce the air flow and, if they
enter the reservoir, could prevent water
drainage. In winter months, make sure
that the air intake is not obstructed by
ice, mud or snow.
IMPORTANT After turning the ignition
key to STOP and having closed the
driver side door, wait at least one
minute before disconnecting the
electrical supply from the battery. When
reconnecting the electrical supply to the
battery, make sure that the ignition key
is in the STOP position and the driver
side door is closed.
