Maserati Levante 2019 Owner's Manual page 358

In an Emergency
• Completely unscrew the five bolts
and remove the wheel.
• Make sure that the contact surfaces
between spare wheel and hub are
clean and free of impurities.
• Fit the compact spare wheel with the
valve stem side out and secure it with
the five bolts previously removed,
without tightening them.
• Remove from the compressor case
6
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 inside one of the
available power outlets fitted in the
boot or passenger compartment.
• Set the ignition device on ACC or
RUN position.
• Turn the compressor on by pressing
the switch.
358
• Stop the compressor pressing
switch again, when the pressure
indicated by the gauge 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 gauge.
• 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.
• Turn anticlockwise the extension
lever of the jack to lower the vehicle
and remove the jack.
• Fully tighten clockwise the bolts,
alternately tightening diametrically
opposite.
WARNING!
•
FOR ALUMINIUM SPARE WHEEL
Observe the tightening torque for
the bolts securing the compact spare
wheel (98 ± 10 Nm/ 72 ± 7 lbf·ft).
• FOR STEEL SPARE WHEEL Observe
the tightening torque for the bolts
securing the compact spare wheel
(86 ± 10 Nm/ 63 ± 7 lbf·ft).
• Bolts must be tightened only after
vehicle is back to ground, so as
to prevent it from falling down
due to the force exerted for bolt
tightening. Failure to comply with
this recommendation can cause
operator injuries.
