In an Emergency
WARNING!
To avoid the risk of forcing the vehicle
off the jack, do not tighten the wheel
bolts fully until the vehicle has been
lowered. Failure to follow this
warning may result in personal injury.

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
242
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 8).
• 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).
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 the
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 (72.3 ±
7 lb/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.
Once finished:
• completely deflate the compact
spare wheel by pressing on the valve
with the overhang of the valve cap;
• place the compact spare wheel and
tool container in the trunk;
• fix everything in place with the
locking knob;
