Modifications or repairs to the fuel feed system that are not carried out properly or do not
take the system’s technical specifications into account can cause malfunctions leading to
the risk of fire.

IMPORTANTIn the event of difficult disengagement, due to significant difference of grip between front and rear axle, do
not insist with heavy accelerations: it is actually more effective an attempt of disengagement at medium slow engine rpm,
with pauses of a few seconds if several attempts are necessary.

tween sidewalls in mm).

(H/S).
R= Radial tyre.
16= Rim diameter in inches. (Ø).
93= Load rating (capacity).
V = Maximum speed index.
WHEELS
RIMS AND TYRES
Alloy rims. Tubeless tyres with radial car-
cass. The homologated tyres are listed
in the Log book.
WARNINGIn the event of discrep-
ancies between the information provid-
ed on this “Owner’s Manual” and the
“Log book”, consider the specifications
shown in the log book only.
On cars fitted with four-wheel drive, all
four tyres should be the same (brand
and track) to prevent damaging the 4-
WD system. The efficiency of the 4-WD
system however, is not jeopardized if
tyres with different wear conditions are
fitted.

COLD TYRE INFLATION PRESSURE
Add +0.3 bar to the prescribed inflation pressure when the tyres are warm. Recheck pressure value with cold tyres.
With snow tyres, add +0.2 bar to the inflation pressure value prescribed for standard tyres.
Inflate tyres to full load pressures if driving at continuous speed exceeding 160 km/h.Tyres
