Frequency of checking coolant level
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;
– an anti-corrosion protection for the cooling system.
No operations should be
carried out on the cooling
circuit when the engine is
hot.
Risk of burns.
Replacement interval
Refer to the Maintenance Document for
your vehicle.
Coolant level
With the engine switched off and on
level ground, the level when cold must
be between the MINI and MAXI marks
on reservoir 1.
Top this level up when cold before it
reaches the MINI mark.
LEVELS (1/3)

When working in the engine
compartment, ensure that
the windscreen wiper stalk
is in the park position.
Risk of injury.For your safety, do not
remove the bonnet holding
straps.
Risk of the bonnet falling
on the road surface.
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).

On the roadPOSSIBLE CAUSESWHAT TO DO
Vibrations. Tyres not inflated to the correct pres-
sure, incorrectly balanced or dam-
aged. Check the tyre pressures: if this is not the
problem, have them checked by an ap-
proved Dealer.
Coolant boiling in the coolant reservoir. Mechanical fault: damaged cylinder
head gasket.Stop the engine.
Contact an approved Dealer.
Smoke under the bonnet. Short circuit or cooling system leak.Stop, switch off the ignition, stand away
from the vehicle and contact an approved
dealer.
The oil pressure warning light comes
on:
while cornering or braking The level is too low. Top up the engine oil level (refer to the in-
formation on “Engine oil level: topping up/
filling” in Section 4).
is slow to go out or remains lit under

Stop the vehicle and contact an approved
Dealer.
OPERATING FAULTS (3/6)

5.33
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 overheats. The coolant
temperature indicator and the warn-
ing light
® come 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.
OPERATING FAULTS (4/6)
Radiator: If there is a lack of coolant, remember that it must never be 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 proportions. Remi\
nder: only products approved by our Technical
Department may be used for this purpose.
