lights Alfa Romeo Giulietta 2015 Repair Manual

IMPORTANT When the weather is cold
or damp or after heavy rain or washing,
the surface of headlights or rear lights,
may steam up and/or form drops of
condensation on the inside. This is
a natural phenomenon due to the
difference in temperature and humidity
between the inside and the outside
of the glass which does not indicate a
fault and does not compromise the
normal operation of lighting devices.
The mist disappears quickly when the
lights are turned on, starting from
the centre of the diffuser, extending
progressively towards the edges.
IMPORTANT
28) Halogen bulbs must be handled
by holding the metallic part only.
Touching the transparent part
of the bulb with your fingers may
reduce the intensity of the
emitted light and even reduce the
lifespan of the bulb. In the case
of accidental contact, rub the
lamp with a cloth and spirit and
leave to dry.
WARNING
127) Changes or repairs to the
electrical system carried out
incorrectly and without due
consideration for the technical
specifications of the system may
lead to malfunctioning and
generate a fire hazard.
128) Halogen bulbs contain
pressurised gas. If they break,
glass fragments could fly
everywhere.
129) Due to the high supply voltage,
gas discharge bulbs (Bi-Xenon)
should only be replaced by
specialised personnel: danger of
death! Contact an Alfa Romeo
Dealership.

SERVICING AND MAINTENANCE

BATTERY
Battery F (see previous pages) does not
require the electrolyte to be topped up
with distilled water. A periodic check
carried out at an Alfa Romeo Dealership
is, however, necessary to check
efficiency.
REPLACING THE
BATTERY
146) 147) 148) 149)
36)
5)
If necessary, replace the battery with
another original battery with the same
specifications. Follow the battery
manufacturer's instructions for
maintenance.
USEFUL ADVICE FOR
EXTENDING THE LIFE OF
YOUR BATTERY
To avoid draining your battery and
make it last longer, observe the
following instructions:
❒when you park the car, ensure that
the doors, tailgate and bonnet are
closed properly, to prevent any lights
from remaining on inside the
passenger's compartment;❒switch off all roof lights inside the car:
the car is however equipped with a
system which switches all internal
lights off automatically;
❒do not keep accessories (e.g. sound
system, hazard lights, etc.) switched
on for a long time when the engine
is not running;
❒before performing any operation on
the electrical system, disconnect
the negative battery cable.
IMPORTANT After the battery is
disconnected, the steering must be
initialised. Thewarning light
switches on to indicate this. To carry
out this procedure, simply turn the
steering wheel all the way from one end
to the other or drive in a straight line
for about a hundred metres.
IMPORTANT If the charge level remains
under 50% for a long time, the battery
is damaged by sulphation, reducing
its capacity and efficiency at start-up.
The battery will also be more at risk
of freezing (this can happen as early as
–10°C). Refer to the paragraph "Car
inactivity" in "Starting and driving"
chapter if the car is left parked for a
long time.If, after purchasing the car, you wish to
install electrical accessories which
require permanent electrical supply (e.g.
alarm, etc.) or accessories which
influence the electrical supply
requirements, contact an Alfa Romeo
Dealership, whose qualified staff will
evaluate the overall electrical
consumption.WARNING
146) Battery liquid is poisonous and
corrosive. Avoid contact with the
skin and eyes. Keep naked flames
and sources of sparks away from
the battery: risk of explosion and
fire.
147) Using the battery with
insufficient fluid irreparably
damages the battery and may
cause an explosion.
148) If the car must remain unused
for a long time at a very low
temperature, remove the battery
and take it to a warm place, to
avoid freezing.
