air filter Alfa Romeo Giulietta 2015 Owner's Manual

During standard use of the vehicle, 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 particulate has
been trapped by the filter.
Since this filter physically traps
particulate, it should be periodically
regenerated (cleaned) at regular
intervals by burning carbon particles.
The regeneration procedure is
controlled automatically by the engine
management control unit according
to the filter conditions and vehicle use
conditions.
During the regeneration there may be a
limited increase in the engine idle
speed, fan activation, a limited increase
in fumes and high temperatures at the
exhaust.
These are not faults; they do not impair
normal car performance or damage
the environment. If the dedicated
message is displayed, see contents of
"Warning lights and messages"
paragraph, in chapter "Knowing the
instrument panel".
WARNING
62) The catalytic converter and
particulate filter (DPF) reach very
high temperatures during
operation. Therefore do not park
the car on flammable materials
(e.g. grass, dry leaves, pine
needles, etc.): fire hazard.

SERVICING AND MAINTENANCE

140) If the engine oil is being topped
up, wait for the engine to cool
down before loosening the filler
plug, particularly for cars with
aluminium plug (for versions/
markets, where provided).
WARNING: risk of burns!
141) The cooling system is
pressurised. If necessary, only
replace the plug with another
original or the operation of the
system may be adversely affected.
Do not remove the reservoir plug
when the engine is hot: you risk
burns.
142) Do not travel with the
windscreen washer reservoir
empty: the windscreen washer is
essential for improving visibility.
Repeated operation of the system
without fluid could damage or
cause rapid deterioration of some
system components.
143) Certain commercial additives
for windscreen washer fluids are
inflammable. The engine
compartment contains hot
components which may set it on
fire.144) Brake fluid is poisonous and
highly corrosive. In the event of
accidental contact, immediately
wash the affected parts with
water and mild soap. Then rinse
thoroughly. Call a doctor
immediately if swallowed.
145) The symbol
on the container
indicates a synthetic brake fluid,
which is different from a mineral
fluid. Using a mineral-type fluid
will damage the special rubber
seals of the braking system
beyond repair.
IMPORTANT
3) Used engine oil and oil filters
contain substances which are
harmful to the environment. You
are advised to contact an Alfa
Romeo Dealership to have the oil
and filters changed.
4) Used transmission fluid contains
substances that are harmful to
the environment. You are advised
to contact an Alfa Romeo
Dealership for oil changes.
