Closing the bonnet
Ensure that the windscreen wiper
blades are correctly positioned.
Place stay 4 back into its holders 5 ,
hold the bonnet in the middle and lower
it to about 20 cm above the closed po-
sition, then release it. It will latch auto-
matically under its own weight.
Ensure that the bonnet is
properly locked.
Check that nothing is pre-
venting the catch from lock-
ing (gravel, cloth, etc.).
Opening the bonnet
Lift the bonnet and release stay 4 from
its holders 5. For your own safety, it is
essential to fix the stay into retainer 3
in the bonnet.
After any procedure in the
engine compartment, make
sure that you do not forget
anything (cloth, tools, etc.).
Otherwise, this may lead to engine
damage or cause a fire.

ENGINE OIL LEVEL: general information (1/2)
If the level is at the minimum
The “TOP-UP OIL LEVEL” message
and warning light
© are displayed
on the instrument panel.
It is vital to top up the oil as soon as
possible.
The display only warns the
driver if the oil level is at the
minimum level. It does not
inform the driver that the oil
level has exceeded the maximum
level as this can only be measured
using a dipstick.
It is normal for an engine to use oil for
lubrication and cooling of moving parts
and it is normal to top up the level be-
tween oil changes.
However, contact an approved Dealer if
more than 0.5 litres is being consumed
every 600 miles (1,000 km) after the
running in period.
Oil change frequency: check the oil
level from time to time and certainly
before any long journey to avoid the
risk of damaging your engine.
Reading the oil level
The oil level should be read with the ve-
hicle on level ground, after the engine
has been switched off for some time.
The dipstick must be used to read
the exact oil level and make sure
that the maximum level has not been
exceeded (risk of engine damage).
Refer to the following pages.
The instrument panel display only
alerts the driver when the oil level is at
its minimum.

ENGINE OIL LEVEL: general information (2/2)
Reading the level using the
dipstick
Engine switched off:
– remove the dipstick and wipe with a clean, lint-free cloth;
– push the dipstick in as far as it will go;
– take out the dipstick again;
read the level: it should never fall below minimum mark C or exceed
maximum mark B.
Once the level has been read, push the
dipstick in as far as it will go.
Consult your approved Dealer at
once if you notice an abnormal or
repeated drop in any of the fluid
levels.
In order to prevent splashback, it is
recommended that a funnel be used
when topping up/filling with oil.
Under no circumstances
should maximum filling
level B be exceeded: this
could damage the engine
and the catalytic converter.
Maximum engine oil level
exceeded.
The oil level should only be read with
the dipstick as explained above.
If the level exceeds the maximum
level, do not start your vehicle and
contact an authorised dealer.C

Topping up/filling
The vehicle must be parked on level
ground and the engine should be cold
(for instance, before the engine is
started up for the first time in the day).
Engine oil grade
Refer to the Maintenance Document for
your vehicle.– Unscrew cap
1;
– top up the level (as a guide, the ca- pacity between the minimum and
maximum reading on the dipstick 2
is between 1.5 and 2 litres, depend-
ing on the engine);
– wait for approximately 10 minutes to allow the oil to drain;
– check the level using the dipstick 2
(as described above).
Once the level is read, ensure that the
dipstick is pushed in as far as it will go
and the cap is completely screwed in.
Do not exceed the MAX level and
do not forget to refit cap 1 and dip-
stick 2.

are changing the oil when
the engine is hot, be careful
not to scald yourself if the
oil overflows.

(very severe damage is likely to be
caused to the engine if it runs out of
coolant).
If the level needs to be topped up, only
use products approved by our Technical
Department which ensure:
– protection against freezing;
– anticorrosion protection of the cool- ing system.
Replacement intervals
