code associated with the maximum
load a tire can carry
Y= Speed Symbol — A symbol
indicating the range of speeds at
which a tire can carry a load
corresponding to its load index
under certain operating conditions.
The maximum speed corresponding
to the speed symbol should only be
achieved under specified operating
conditions (i.e., tire pressure, vehicle
loading, road conditions, and posted
speed limits)
Load Identification:

the sidewall of the tire indicates a
Standard Load (SL) tire
XL= Extra Load (or reinforced) tire
LL= Light Load tire
Tire Identification Number (TIN)
The TIN may be found on one or both
sides of the tire, however the date
code may only be on one side. Tires
with white sidewalls will have the full
TIN, including the date code, located
on the white sidewall side of the tire.Look for the TIN on the outboard side
of black sidewall tires as mounted on
the vehicle. If the TIN is not found on
the outboard side, then you will find it
on the inboard side of the tire.
EXAMPLE: DOT MA L9 ABCD 0313
DOT= Department of Transportation
— This symbol certifies that the tire is
in compliance with the U.S.
Department of Transportation tire
safety standards and is approved for
highway use.

• Remove from the compressor case
the inflation hose and the cable with
a plug for the power outlet.
• Unscrew the valve cap of the
compact spare wheel and screw the
fitting of the inflation hose onto the
valve.
• Insert the plug in one of the
available power outlets fitted in the
trunk or passenger compartment.
• Turn the key in the ignition switch in
MAR (ON)position.
• Turn the compressor on by pressing
the switch.
• Stop the compressor pressing switch
again, when the pressure indicated
by the gage reaches the
recommended level (see “Tire
Inflation Pressure” in section
“Features and Specifications”) and
screw the cap on the compact spare
wheel valve.
CAUTION!
• In order to obtain a more accurate
reading, the compressor should be
switched off when checking the tire
pressure of the compact spare wheel
on the pressure gage.
• Do not run the compressor for more
than 20 minutes: there is a risk it
could overheat. Also, prolonged
power absorption may discharge the
battery, subsequently preventing the
engine from starting.
• The compressor has been designed
exclusively to inflate compact spare
wheels; do not use it to inflate air
mattresses, dinghies etc.
• Fit the adapter on the wrench.
Extend the wrench as shown, then
loosen by approximately one turn,the five bolts on the wheel to be
changed.
• Open the jack partially, releasing and
turning the control lever clockwise.
• Place the jack near the wheel to be
changed in one of the indicated
positions.
• Make sure that the head of the jack
is correctly inserted in one of the
slots beneath the sole bar.

approximately 44 lb (20 kg) being
placed on the handle of the wrench
supplied when extended for use.
•After refitting the standard wheel,
check the tire pressure.
WARNING!
•The spare wheel is narrower than
standard wheels and must only be
used to travel the distance required
to reach a service station, where the
punctured tire can be repaired or
replaced.
•Do not exceed a maximum speed of
50 mph (80 km/h) when using the
compact spare wheel; when this
limit is exceeded, the stability, road
holding and braking of the vehicle
will be compromised. Avoid
accelerating to full speed, heavy
braking and fast cornering.
•The compact spare wheel must be
inflated to the recommended tire
pressure (see “Tire Inflation
Pressure” in section “Features and
Specifications”).
•For safety reasons, it is absolutely
forbidden to drive with more than
one compact spare wheel fitted on
the vehicle.•Snow chains cannot be fitted on the
compact spare wheel.
•The spare wheel can travel a
maximum of 1,800 mi (3.000 km).
NOTE:
The used wheel may soil the mats if it
is housed in the car: insert the used
wheel in the protective bag housed in
the side pocket of the covering bag.
To Refit the Standard Wheel with
Repaired or Replaced Tire
• Following the procedure and the
caution described above, raise the
vehicle and remove the compact
spare wheel reusing the supplied
wrench with adapter, suitably
extended.
• Fit the standard wheel with repaired
or replaced tire.
• Tighten the original bolts on the
wheel.
• Lower the vehicle and remove the
jack.
• Fully tighten the bolts, alternately
tightening diametrically opposite.
WARNING!
•Observe the tightening torque for
the bolts securing the wheels (72 ±
7 lbf·ft / 98 ± 10 Nm). This is
equivalent to a load of
approximately 44 lb (20 kg) being
placed on the handle of the wrench
supplied when extended for use.
•After refitting the standard wheel,
check the tire pressure.
Once finished:
• completely deflate the compact
spare wheel by pressing on the valve
with the overhang of the valve cap;
• wrap the power cable and the
inflation hose inside the compressor
case;
• place the compressor, the jack, the
wrench and the adapter in the

Brake Fluid Level Check
Check the fluid level immediately if
the brake system
red warning
light and the related message turn on
indicating a low level of brake fluid.
• Clean the brake fluid reservoir area
around the cap before removing it.
• Add fluid to bring the level up to the
“MAX” mark on the side of the
master cylinder reservoir. Use only
manufacturer's recommended brake
fluid (see “Refillings” in section
"Features and Specifications").
• Once the correct level is reached,
firmly close the cap.
The brake pads wear could cause the
fluid level to fall. However, low fluid
level may be caused by a leak and arequires accurate checkup of the
braking system.
CAUTION!
The symbol
on the tank cap
identifies the synthetic type of brake
fluid, distinguishing it from the
mineral type. Using mineral fluids
damages the special rubber linings of
the brake system irreparably.
WARNING!
California Proposition 65
Operating, servicing and maintaining
a passenger vehicle or off-road vehicle
can expose you to chemicals including
such as, engine exhaust, carbon
monoxide, phthalates and lead, that
which are know to the State of
California to cause cancer and birth
defects or other reproductive harm. To
minimize exposure, avoid breathing
exhaust, do not idle the engine except
as necessary, service your vehicle in a
well-ventilated area and wear gloves
or wash your hands frequently when
servicing your vehicle. For more
information go to:www.P65Warnings.ca.gov/passenger-
vehicle
WARNING!
•To avoid contamination from foreign
materials or moisture, use only new
brake fluid or fluid that has been in
a tightly closed container. Keep the
master cylinder reservoir cap secured
at all times. Brake fluid in an open
container absorbs moisture from the
air resulting in a lower boiling point.
This may cause it to boil
unexpectedly during hard or
prolonged braking, resulting in
sudden brake failure. This could
result in an accident.
•Overfilling the brake fluid reservoir
can result in spilling brake fluid on
hot engine parts, causing the brake
fluid to catch fire. Brake fluid can
also damage painted and vinyl
surfaces, make sure it does not spill
over these surfaces.
•Do not allow petroleum based fluid
to contaminate the brake fluid.
Brake seal components could be
damaged, causing partial or
complete brake failure. This could
result in an accident.

Useful Advice to Extend
Battery Life
When parking the vehicle, make sure
that the doors, front, rear lids and
flaps are properly closed. All interior
lights should be off.
When the engine is turned off, do not
keep the connected devices switched
on for a long time (such as radio,
hazard warning flashers, fan, etc.).
CAUTION!
If the battery charge remains below
50% for a long period of time, it will
be damaged due to sulfation; its
performance and starting power will
be reduced and it will be more subject
to freezing (this can happen even at
14°F/-10°C).
We recommend you to have the
battery charge condition checked,
preferably at the beginning of the
cold season, to prevent the electrolyte
from freezing.
This check should be carried out more
frequently if the vehicle is used mainly
for short trips or if it is equipped with
power absorbing devices that remain
permanently on even when the
ignition switch is off. This appliesabove all if these devices have been
retrofitted ("Aftermarket" services).
If the vehicle is not used for long
periods of time, please see “Vehicle
Stored for Long Periods” in this
section.
Battery Recharge
WARNING!
The process of charging or recharging
the battery produces hydrogen, a
flammable gas that can explode and
cause serious injuries. When charging
or recharging the battery, follow the
recommended precautions at all
times.
•Before using a charger device
always check that this tool is
suitable for the installed battery,
with constant voltage (lower than
14.8 V) and low amperage
(maximum limit 15 A).
•Recharge the battery in a
well-ventilated environment.
•Never charge or recharge a frozen
battery: it can explode due to
hydrogen trapped inside the ice
crystals.
•Ensure that any sparks or open
