Replacement intervals
Refer to the Maintenance Document for
your vehicle.
Checking intervals
Check the coolant level regularly

(very severe damage is likely to be
caused to the engine if it runs out of
coolant).
If the level needs to be topped up, only
use products approved by our Technical
Department which ensure:
– protection against freezing;
– anticorrosion protection of the cool- ing system.
LEVELS (1/3)
Coolant level
With the engine switched off and on
level ground, the level when cold must
be between the “MINI" and "MAXI"
marks on coolant reservoir 1.
Top this level up when cold before it
reaches the MIN mark.
No operations should be
carried out on the cooling
circuit when the engine is
hot.
Risk of burns.
Consult your approved dealer at
once if you notice an abnormal or
repeated drop in any of the fluid
levels.
Please note when work-
ing close to the engine that
it may be hot. The engine
cooling fan may also start
at any moment. The
 warning
light in the engine compartment re-
minds you of this.
Risk of injury.
1
Before performing any
action in the engine com-
partment, the ignition must
be switched off (please see
the information on “Starting, stop-
ping the engine” in Section 2).

OPERATING FAULTS (5/7)
On the roadPOSSIBLE CAUSESWHAT TO DO
Steering becomes heavy. Assistance overheating.
Fault with the electric assistance
motor.
Fault in the assistance system. Drive carefully at reduced speed, be aware
of the level of force in the steering wheel
needed to turn the wheels. Consult an ap-
proved dealer
The engine is overheating. The cool-
ant temperature indicator is in the
warning zone and warning light
® comes on. Engine cooling fan not working. Stop the vehicle, switch off the engine and
contact an approved dealer.
Coolant leaks. Check the coolant reservoir: it should con- tain fluid. If there is no coolant, consult an
approved dealer as soon as possible.
Coolant boiling in the coolant reser-
voir. Mechanical fault: damaged cylinder
head gasket. Stop the engine.
Contact an approved dealer.
Radiator:
If there is a significant lack of coolant, remember that it must never b\
e topped up using cold coolant while
the engine is very warm. After any procedure on the vehicle which has involved even partial drain\
ing of the cooling
system, it must be refilled with a new mixture prepared in the correct p\
roportions. Reminder: only products approved
by our Technical Department may be used for this purpose.
