A cold engine uses more fuel than a
warm engine. It is not necessary to
‘‘warm-up’’ a cold engine by letting it
idle for a long time. You can drive
away in about a minute, no matter
how cold it is outside. The engine
will warm up faster, and you get
better fuel economy. To cut down on
the number of ‘‘cold starts,’’ try to
combine several short trips into one.
You can improve fuel economy by
driving moderately. Rapid acceler-
ation, abrupt cornering, and hard
braking use more fuel.
Always drive in the highest gear that
allows the engine to run and acceler-
ate smoothly.
The air conditioning puts an extra
load on the engine which makes it

cut down on air conditioning use.
Use the flow-through ventilation
when the outside air temperature is
moderate.
The condition of your car and your
driving habits are the two most
important things that affect the fuel
mileage you get.
Always maintain your car according
to the maintenance schedule. This
will keep it in top operating condition.
Depending on traffic conditions, try
to maintain a constant speed. Every
time you slow down and speed up,
your car uses extra fuel. Use the
cruise control, when appropriate, to
increase fuel economy.
An important part of that mainte-
nance is the
(see page ). For
example, an underinflated tire
causes more ‘‘rolling resistance,’’
which uses fuel. It also wears out
faster, so check the tire pressure at
least monthly.
In winter, the build-up of snow on
your car’s underside adds weight and
rolling resistance. Frequent cleaning
helps your fuel mileage and reduces
thechanceofcorrosion.
