FUNCTIONING
Checks performed before starting the engine
q During refuelling and oil topping-up, do not smoke, and for the level checks do not use open flames or
lighting means that have not been type-approved, as they may cause fire.
q If during topping-up fuel, oil or lubricant is spilled, immediately clean the areas stained.
Carry out the checks listed below every day before starting the engine.
Check the coolant level and top up
q Do not remove the radiator cap, unless such operation is absolutely necessary. Before checking the
coolant level, wait for the engine to cool down and check the expansion tank.
q Immediately after the engine has stopped, the coolant is very hot and under pressure. Removing the
cap in these conditions to check the coolant level may cause a burn hazard. Before removing the cap,
wait until temperature is reduced and loosen the cap slowly to release the remaining pressure.
1. Open the lateral cover and check that the coolant level is
between the FULL and LOW markings on the radiator
expansion tank (1) (shown in the figure on the right). If the
level is low, add coolant through the filler neck up to the
FULL mark.
2. Put back the cap after topping up.
3. If the expansion tank is empty, make sure that there are no
leakages and check the coolant level in the radiator. If
necessary, add coolant in the radiator and also in the
expansion tank.
