Fuel Consumption; Calculating Fuel Economy; Filling The Tank - Ford 2015 FOCUS Owner's Manual

1. Stop your vehicle as soon as safely
possible and shift the transmission into
park (P).
2. Open the fuel filler door and remove
any visible debris from the fuel fill
opening.
3. Insert either the fuel fill nozzle or the
fuel fill funnel provided with the vehicle
several times to allow the inlet to close
properly. This will dislodge any debris
preventing the inlet from sealing.
If this action corrects the problem, the
message may not reset immediately. It
may take several driving cycles for the
message to turn off. A driving cycle
consists of an engine start-up (after 4 or
more hours with the engine off) followed
by city or highway driving. Continuing to
drive with the message on may cause the
service engine soon lamp to turn on as
well.

FUEL CONSUMPTION

Note: The amount of usable fuel in the
empty reserve varies and should not be
relied upon to increase driving range. When
refueling your vehicle after the fuel gauge
indicates empty, you might not be able to
refuel the full amount of the advertised
capacity of the fuel tank due to the empty
reserve still present in the tank.
Empty reserve is the amount of fuel
remaining in the tank after the fuel gauge
indicates empty. Do not rely on this fuel for
driving. The usable capacity of the fuel
tank is the amount of fuel that can be put
into the tank after the gauge indicates
empty. The advertised capacity is the total
fuel tank size – it is the combined usable
capacity plus the empty reserve.

Calculating Fuel Economy

Do not measure fuel economy during the
first 1000 miles (1600 kilometers) of
driving (this is your engine's break-in
period); a more accurate measurement is
obtained after 2000 miles - 3000 miles
(3200 kilometers - 4800 kilometers). Also,
fuel expense, frequency of fill ups or fuel
gauge readings are not accurate ways to
measure fuel economy.

5. Calculate fuel economy by dividing
Keep a record for at least one month and
record the type of driving (city or highway).
This provides an accurate estimate of the
vehicle's fuel economy under current
driving conditions. Additionally, keeping
records during summer and winter show
how temperature impacts fuel economy.
In general, lower temperatures mean lower
fuel economy.

inaccurate reading results if the engine
is left running.

Allow no more than two automatic
