When the engine is
running, this indicates the
temperature of the coolant.
Range
When the engine is
running, this indicates
the distance which can
still be travelled with the
fuel remaining in the tank
based on the average
fuel consumption over the
last few miles/kilometres
travelled. This value may vary following a change
in the style of driving or the relief,
resulting in a large variation in the
current fuel consumption.
If you only add a few litres, the value
displayed will be incorrect. Therefore,
you must fill the tank whenever
possible.
Coolant temperature
gauge
If the bar is close to the critical
position located
on the right, the temperature is too high.
The symbol flashes when your engine is
overheating.
You must stop your vehicle as soon as it is
safe to do so.
Wait a few minutes before switching off the
engine. When the range is less than 30 miles (50 km)
,
dashes are displayed.
Refuel as soon as possible. The display of the
range is updated.
Wait for the engine to cool before
topping up the level. The cooling system
is pressurised.
To avoid any risk of scalding, unscrew
the cap by two turns to allow the
pressure to drop.
When the pressure has dropped,
remove the cap and top up the level,
if
necessary.
Contact a CITROËN dealer or a
qualified workshop. When you disconnect the battery,
the previous fuel consumption data
is lost and the value displayed will be
different from that displayed before the
battery was disconnected. The distance
displayed must be considered an
approximate indication.
