When the meter is activated, all of the fuel
level meter segments and all indicators come
on. After a few seconds, the fuel level meter
displays the remaining amount of fuel and all
indicators go off.
EJU45620Fuel level meter
The fuel level meter shows the amount of fuel
remaining in the fuel tank. The amount of re-
maining fuel is shown using four display seg-
ments, which disappear one at a time as the
fuel level decreases.
TIP:
The accuracy of the fuel level meter varies
depending on the operating conditions. Use
this function as a reference only.
EJU45631Fuel level warning
If the fuel remaining in the fuel tank drops to
about 6.0 L (1.59 US gal, 1.32 Imp.gal), the
lowest fuel level segment blinks.
If the fuel level warning is activated, refill the
fuel tank as soon as possible. (See page 31
for information on filling the fuel tank.)
