Topping up coolant

The coolant cools the internal combustion
engine to the correct operating temperature.
The heat that is transferred from the engine
to the coolant can be used to heat the pas-
senger compartment.
When topping up the coolant, follow the
instructions on the packaging. Never top up
with water only. The risk of freezing increases
with both too little and too much coolant con-
centrate.
If there is coolant under the car, if there is
coolant smoke, or if more than 2 litres (approx.
2 quarts) have been filled, always call for
recovery to avoid the risk of engine damage
due to a defective cooling system when
attempting to start the car.
WARNING
The coolant may be very hot. Never open
the cap when the coolant is hot. If a top-up
is required, unscrew the expansion tank
cap slowly to allow any overpressure to
disappear.
