IMPORTANT
Make
sure
not
to
add
too

much
engine
oil
when
topping
up.
Engine

oil
in
excess
may
damage
the
engine.

Have
the
car
checked.
Never
exceed
the

MAX
level
when
topping
up
engine
oil.
It
is advisable to check the oil level in
intermediate steps on the display.
IMPORTANT The oil level is not refreshed
immediately on the display after topping
up. Consequently, wait for the oil level to
be refreshed on the display following to
procedure shown below.
Top-up and oil level indication update
on display
If a top-up is needed, proceed as follows
to ensure correct indication of the oil
level on the display:
2.0 T4 MAir engine
with the vehicle level, run the engine
for approximately 5 minutes
(temperature higher than 176°F (80°C)
and then stop the engine;
start the engine again and idle it for
about 2 minutes.
2.2 JTD Engine
with the car level, run the engine until
the second oil temperature notch lights
up on the display on the instrument panel,
then stop the engine;
wait for at least 3 minutes, turn the
ignition switch to ON without starting the
engine and wait for 20 seconds.
IMPORTANT If the indication is not
correct after the procedure, contact an
Alfa Romeo Dealership.IMPORTANT The oil dipstick in the engine
compartment, on versions with 2.2 JTD
engine, must be used ONLY if the oil level
sensor is faulty. The latter condition is
indicated by the
symbol which will
appear on the instrument panel.
The manual engine oil level checking
procedure must be carried out, when
necessary, on a cold engine only.
Never attempt to carry out the manual
engine oil checking procedure (using the
dipstick) with the engine hot. Contact
with the surrounding hot engine parts
could cause burns.
This operation is permitted only for the
time actually needed to restore correct
operation of the oil level sensor at an Alfa
Romeo dealership.
Engine oil consumption
68)
4)
The maximum engine oil consumption is
usually 0.88 lb (400 grams every
620 miles (1000 km). When the car is
new, the engine needs to be run in,
therefore the engine oil consumption can
only be considered stabilised after the
first 3100 - 3700 miles (5000 -
6000 km).

SERVICING AND CARE

ENGINE COOLANT FLUID
159)
69)
If the level is too low, unscrew the
reservoir cap and add the fluid described
in the "Technical Specifications" chapter.
On the 2.0 T4 MAir engine version with
right-hand drive, remove the shield 6
fig. 154 to check the fluid level in the
primary reservoir. To do this, release the
fixing clip 7 and lift upwards.
WASHER FLUID FOR WINDSCREEN/
HEADLIGHTS
160) 161)
The windscreen and headlights washer
fluid reservoir (where provided) is
equipped with a telescopic filler. If the
level is too low, lift the reservoir cap 4
fig. 155 upwards and then lift the filler,
as shown in the figure, and add the fluiddescribed in the "Technical
Specifications" chapter. After having
topped up the fluid, arrange the filler
correctly and then press on the cap until
you hear it click.
IMPORTANT With a low fluid level
(indicated by the dedicated symbol
appearing on the instrument panel
display), the headlight washer system
does not work, even though the screen
washers continue to work.BRAKE FLUID
Check that the fluid is at the max. level. If
the liquid level in the tank is insufficient,
contact an Alfa Romeo Dealership to
have the system checked.
AUTOMATIC TRANSMISSION
ACTIVATIONSYSTEM OIL
5)
The transmission control oil level should
only be checked at an Alfa Romeo
Dealership.
BATTERY
162) 163) 164) 165)
70)
6)
The battery 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.
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
15409026S0007EM
15509086S0666EM
171

This function can only be activated within
2 minutes of setting the ignition device
to STOP.
To activate this function, move the lever
upwards (unstable position) for at least
three seconds.
If, after using the function, the ignition
device is set back to ON with the blades
in a position other than rest position (at
the base of the windscreen), they will only
return to rest position following a
command given using the stalk (stalk
upwards, into unstable position) or when
a speed of 3 mph (5 km/h) is exceeded.
Replacing the windscreen wiper blades
Proceed as follows:
raise the wiper arm, press tab
fig. 159 of the attachment spring and
remove the blade from the arm;
fit the new blade, inserting the tab in
the dedicated housing in the arm and
checking that it is locked;
lower the wiper arm onto the
windscreen.
IMPORTANT Do not operate the
windscreen wiper with the blades lifted
from the windscreen.
Windscreen washer
The window washer nozzles are fixed. If
there is no jet of fluid, firstly check that
there is fluid in the reservoir (see
paragraph “Engine compartment” in this
chapter).
Then check that the nozzle holes are not
clogged; use a needle to unblock them if
necessary.
WARNING
168)The air intake system (air cleaner,
rubber hoses, etc.) can be a protection in the
case of blowbacks from the engine. DO NOT
REMOVE this system unless you need to
carry out repair or servicing operations.
Before starting the engine, ensure that the
system has not been removed: failure to
observe this precaution may result in serious
injury.
169)Exhaust emissions are very dangerous,
and may be lethal. They contain carbon
monoxide, a colourless, odourless gas which
can cause fainting and poisoning if inhaled.
170)The exhaust system may reach high
temperatures and may cause a fire if the
vehicle is parked on flammable material. Dry
grass or leaves can also catch fire if they
come into contact with the exhaust system.
Do not park or use the vehicle in a place in
which the exhaust system might come into
contact with flammable material.
IMPORTANT
72)Incorrect servicing of the vehicle or
failure to carry out operations or repairs
(when necessary) may lead to more
expensive repairs, damage to other
components or have a negative impact on
the vehicle performance. Have any
malfunction inspected immediately by an
Alfa Romeo Dealership.

recheck that the value is correct with the tyre cold.
If it is necessary to raise the vehicle, refer to the "Raising the vehicle" paragraph in the "In an emergency" chapter.
The pressures given below apply to all tyre types: summer, winter and all season (where provided).
