The fuel gauge shows approximately how
much fuel is remaining in the tank when
the ignition is switched ON. We
recommend keeping the tank over 1/4 full.

If the low fuel warning light illuminates or
the fuel level is very low, refuel as soon as
possible.
If inconsistency in engine performance or
stalling occurs due to low fuel level
conditions, refuel the vehicle as soon as possible and add at least 10 L (2.7 US
gal,
2.2 Imp gal) of fuel.
Refer to Taking Action.
