CAUTION!
• When the key on the key in the
ignition switch is in theMAR (ON)
position and if the indicator light
does not switch on or if it switches
on while driving, contact an
Authorized Maserati Dealeras soon
as possible.
• Prolonged driving with the MIL on
could cause damage to the engine
control system. It also could affect
fuel economy and drivability. If the
MIL is flashing, severe catalytic
converter damage and power loss
will soon occur. Immediate service is
required.
Parking Lights Indicator
With the key removed from
the ignition switch, it indicates
that the parking lights are on.
Transmission Failure Warning Light (*)
Depending on the message
displayed it signals:
• a transmission failure. If the
failure permits, slowly drive
to the nearestAuthorized
Maserati Dealer;• a too high temperature of the
transmission oil. In this case, slow
down until the temperature goes
down to the normal values for use
(the warning light goes off).
For further information see chapter
“Automatic Transmission” in section
“Driving”.
CAUTION!
Continuous driving with the
transmission temperature warning
light illuminated will eventually cause
severe transmission damage or failure.
WARNING!
If the transmission temperature
warning light is illuminated and you
continue operating the vehicle, in
some circumstances you could cause
the fluid to boil over, come in contact
with hot engine or exhaust
components and cause a fire.
High Beam Indicator
This indicator lights up when
the high beams are switched
on or when blinking.Low Oil Pressure Warning Light (*)
Under normal conditions, the
warning light illuminates
when the key in the ignition
switch is turned toMAR (ON)
position and goes off as soon as the
engine is started.
If the warning light stays or turns on
while driving, the engine oil pressure is
too low. The warning light is combined
with a displayed message. In this case,
turn the engine off immediately and
carry out the necessary checks.
Do not operate the vehicle until the
problem has been solved. This light
does not indicate the oil level. The
engine oil level must be checked with
the dipstick located under the hood
(see “Maintenance Procedures” in
section “Maintenance and Care”).
If the problem persists, contact an
Authorized Maserati Dealer.
Headlight On Indicator
This indicator will illuminate
when the position lights or
headlights are turned on.

•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

the related message of low oil level
displays, or during scheduled services
(see “Scheduled Maintenance Service”
in this section) it is necessary to check
the engine oil level.
The vehicle should be parked on level
ground to improve the accuracy of the
oil level readings.
CAUTION!
• Do not top up with oil with different
characteristics than the engine one
(refer to “Refillings” in section
“Features and Specifications”).
• Overfilling or underfilling the oil pan
will cause aeration or loss of oil
