another car, check that there is no
accidental contact between metallic
parts of the two cars.
BUMP STARTING
Never, under any circumstances, jump
start the engine by pushing, towing or
coasting downhill.
FUEL CUT-OFF SYSTEM
OPERATION
This intervenes in the case of an impact
causing:
❒ the fuel supply cut-off with the engine
consequently switching off;
❒ automatic door lock release;
activation of all lights inside the car;
❒ the switching on of the hazard
warning lights.
The digital warning light and the
dedicated message on the display
indicate the intervention of the system.
Carefully check the vehicle for fuel leaks,
for instance in the engine compartment,
under the vehicle or near the tank area.

111)This procedure must be performed
by qualified personnel as incorrect
actions may cause high-intensity
electrical discharge. Furthermore,
battery fluid is poisonous and corrosive:
avoid contact with skin and eyes. Keep
naked flames and lighted cigarettes away
from the battery and do not cause sparks.
IMPORTANT
13)Never use a fast battery charger to
start the engine as this could damage the
electronic systems and the ignition and
engine supply control units.
