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.

RIMS AND TYRES
Pressed steel or alloy rims. Tubeless tyres
with radial carcass. The homologated
tyres are listed in the Log book.
IMPORTANTIn 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.
A0E0186mfig. 5
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.
Attaining to the prescribed size, to en-
sure safety of the car in movement, it
must be fitted with tyres of the same
make and type on all wheels.
IMPORTANTDo not use inner tubes
with Tubeless tyres.
SPACE-SAVER SPARE WHEEL

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.
