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.
NOTE:
For the tire repair procedures with tire
repair kit see instructions included in
the kit.
This kit will provide a temporary tire
seal, allowing you to drive your
vehicle up to 6 miles (10 km) with a
maximum speed of 50 mph (80 km/h).
CAUTION!
• Intruding objects (e.g., screws or
nails) should not be removed fromthe tire, which could compromise
the repair with the tire repair kit.
• Do not use the tire repair kit if the
tire shows lateral damages and/or
the rim is damaged by driving with
flat tire.
• Tire repair kit can be used in outside
temperatures down to
approximately -4°F (-20°C).
• Replace the tire repair kit sealant gas
cylinder prior to the expiration date
(printed on the gas cylinder label) to
assure optimum operation of the
system.
NOTE:
•The compressor power plug can be
inserted either in the 12 V power
outlet housed in the trunk or inside
the passenger compartment (see
“Interior Features” in section
“Understanding the Vehicle”).
•When having the tire serviced,
advise theAuthorized Maserati
Dealeror service center that the tire
has been sealed using the tire repair
kit.
Using the Compact Spare
Wheel (for versions/markets
where provided)
Upon request, the vehicle may come
equipped with a compact spare wheel
(emergency wheel), jack and tools for
replacing a wheel.
The compact spare wheel is stored in
the trunk and housed in a bag: it is
supplied deflated in order to limit the
amount of space occupied. An electric
compressor is also provided for
inflating.
The bag covering the compact spare
wheel has a side pocket containing
the protective bag for the standard
wheel that has been removed along
with a pair of gloves.
In the event of a tire puncture,
proceed as follows.
• Stop the vehicle in a place that does
not constitute a danger to traffic
and where the wheel can be
changed safely. The vehicle must be
level and on firm ground.
• Select the P (Park) mode and then
engage manually the electric
parking brake and turn the key in
the ignition switch toSTOP (OFF)
position.

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
