User precautions
– Before opening the tailgate, ensure that the surrounding space is suffi-
cient to permit operation of the tail-
gate. Otherwise, stop the movement
of the boot lid before it makes con-
tact.
– The system may experience tempo- rary difficulties if one of the sensors
integrated in the rear of the bumper
is obscured (by dirt, mud, snow, grit-
ting salt, etc.). Clean the sensors. If
there is still a problem, contact an
approved dealer.
Note: in very cold weather conditions,
the automatic opening may not work if
the tailgate seals are frozen.

ment reminds you of this.
Risk of injury.

4.4
ENGINE OIL LEVEL: general information
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 your 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. – remove the dipstick and wipe with a
clean, lint-free cloth;
– push the dipstick in as far as it will go (for vehicles equipped with a cap-
type dipstick C, screw the cap in as
far as it will go);
– take out the dipstick again;
– read the level: it should never fall below minimum mark A or exceed
maximum mark B.
Once the operation has been com-
pleted, ensure that the dipstick is
pushed in as far as it will go or that
the “cap-type dipstick” is completely
screwed in.

In order to prevent splashback, it is
recommended that a funnel be used
when topping up/filling with oil
Before performing any
action in the engine com-
partment, the ignition must
be switched off (please see
the information on “Starting, stop-
ping the engine” in Section 2).
Exceeding the maximum
engine oil level
Under no circumstances
must the maximum fill
level B be exceeded: risk of damage
to the engine and catalytic con-
verter.
If the oil level exceeds the maximum
level, do not start your vehicle and
contact an approved Dealer.

4.5
ENGINE OIL LEVEL: topping up, filling (1/3)
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).– Unscrew cap
1;
– top up the level (as a guide, the ca- pacity between the “ mini" and the
" maxi" reading on the dipstick 2
is between 0.33 and 0.44 gallons
(1.5 and 2 litres) depending on the
engine);
– wait for approximately 20 minutes to allow the oil to flow into the engine;
– check the level using the dipstick 2
(as described above).
Once the operation has been com-
pleted, ensure that the dipstick is
pushed in as far as it will go or that
the “cap-type dipstick” is completely
screwed in.
Do not exceed the “maxi" level and
do not forget to refit the cap 1 and
the dipstick 2.

Replacement intervals
Refer to the Maintenance Document for
your vehicle.
Checking intervals
Check the coolant level regularly

(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.
LEVELS (1/3)
Coolant level
With the engine switched off and on
level ground, the level when cold must
be between the “MINI" and "MAXI"
marks on coolant reservoir 1.
Top this level up when cold before it
reaches the MIN mark.
No operations should be
carried out on the cooling
circuit when the engine is
hot.
Risk of burns.
Consult your approved dealer at
once if you notice an abnormal or
repeated drop in any of the fluid
levels.
Please note when work-
ing close to the engine that
it may be hot. The engine
cooling fan may also start
at any moment. The
 warning
light in the engine compartment re-
minds you of this.

LEVELS (2/3)
Brake fluid level
This should be checked frequently, and
any time you notice even the slightest
loss in braking efficiency.
The level should be read with the engine
switched off and on level ground.Level 2
It is normal for the level to drop as
the linings become worn, but it should
never drop below the “MINI” warning
line.
If you wish to check the disc and drum
wear yourself, you should obtain the
document explaining the checking pro-
cedure from our network or from the
manufacturer’s website. Topping up
After any operation on the hydraulic cir-
cuit, a specialist must replace the fluid.
Only use fluids approved by our
Technical Department (and taken from
a sealed container).

BATTERY (1/2)
1
Battery 1 does not require any mainte-
nance. You should not open it or add
any fluid.
Handle the battery with care
as it contains sulphuric acid
which must not come into
contact with the eyes or
skin. If it does, wash the affected
area with plenty of cold water. If
necessary, consult a doctor.
Ensure that naked flames, red hot
objects and sparks do not come into
contact with the battery as there is a
risk of explosion.
Please note when work-
ing close to the engine that
it may be hot. In addition,
the engine cooling fan may
start at any moment. The

warning light in the engine compart-
ment reminds you of this.
Risk of injury.
Before performing any
action in the engine com-
partment, the ignition must
be switched off (please see
the information on “Starting, stop-
ping the engine” in Section 2).
Depending on the vehicle, a system
continuously checks the battery charge
status. If this decreases, the message
“Battery low start engine” is displayed
on the instrument panel. In this case,
start the engine. The message will go
off.
The charge status of your battery can
decrease especially if you use your ve-
hicle:
– for short journeys;
– for driving in town;
– when the temperature drops;
– after extended use of energy-con- suming devices (radio, etc.) with the
engine switched off.

TYRE PRESSURE KIT (3/3)
3
If a minimum pressure of 1.8 bar is
not reached after 15 minutes, repair
is not possible; do not drive the ve-
hicle but contact an approved dealer.Once the tyre is correctly inflated,
remove the kit: slowly unscrew the in-
flation end piece
3 to prevent any prod-
uct spatter and store the container in
plastic packaging to prevent product
leaks.
– Affix the driving recommendation label (located under the container) to
the dashboard where the driver can
see it.
– Put the kit away.
– At the end of this initial inflation op- eration, air will still escape from the
tyre. You must drive a short distance
in order to seal the hole.
– Start immediately and drive at be- tween 12 and 40 mph (20 and
60 km/h) in order to distribute the
product evenly in the tyre and, after
driving for 2 miles (3 km), stop and
check the pressure.
– If the pressure is greater than 1.3 bar but less than the recommended
pressure, re-adjust it (refer to the
label affixed to the edge of the driv-
er’s door), otherwise contact an ap-
proved dealer: repair is not possible.
Please be aware that a
poorly tightened or miss-
ing valve cap can make the
tyres less airtight and may
lead to pressure loss.
Always use valve caps identical to
those fitted originally and tighten
them fully.
Following repair with the kit,
do not travel further than
120 miles (200 km). In addi-
tion, reduce your speed and
under no circumstances exceed
48 mph (80 km/h). The sticker,
which you must affix in a prominent
position on the dashboard, reminds
you of this.
Depending on the country or local
legislation, a tyre repaired with the
inflation kit may need to be replaced.
Nothing should be placed
around the driver’s feet
as such objects may slide
under the pedals during
sudden braking manoeuvres and
obstruct their use.
Precautions when using the
kit
The kit should not be operated for more
than 15 consecutive minutes.
