In an Emergency
level (see chapter "Tire Inflation
Pressure" in section "Technical
Specifications") and screw the cap on
the spare wheel valve.

• In order to obtain a more accurate
reading, the compressor should be
switched off when checking the tire

pressure of the 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 spare wheels;
do not use it to inflate air mattresses,
dinghies etc.

• Turn anticlockwise the lever of the jack
to lower the vehicle and remove the
jack.
• Fully tighten clockwise the bolts,
alternately tightening diametrically
opposite.
WARNING!
•
Observe the tightening torque for the
bolts securing the spare wheel (120 ±
12 Nm/ 88,5 ± 9 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.
WARNING!
• The spare wheel 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
80 km/h (50 mph) when using the
spare wheel, as indicated on the
label applied on it; 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 spare wheel must be inflated to
the recommended tire pressure (see
chapter "Tire Inflation Pressure" in
section "Technical Specifications").
• For safety reasons, it is absolutely
forbidden to drive with more than one
spare wheel fitted on the vehicle.
• Snow socks cannot be fitted on the
spare wheel.
•
The spare wheel can travel a maximum
of 3000 km (1800 mi).
To Refit the Standard Wheel with
Repaired or Replaced Tire
• Following the procedure and the
caution described above, raise the
vehicle and remove the spare wheel
reusing the supplied spanner.
