ECONOMICAL DRIVING
Your fuel economy is affected by several
things, such as how you drive, the
conditions you drive under, and how you
maintain your vehicle.
You may improve your fuel economy by
keeping these things in mind:
•
Accelerate and slow down in a smooth,
moderate fashion.
•
Drive at steady speeds without
stopping.
•
Anticipate stops; slowing down may
eliminate the need to stop.
•
Close the windows for high-speed
driving.
•
Drive at reasonable speeds. Traveling
at 55 mph (90 km/h) uses 15% less
fuel than traveling at 65 mph
(105 km/h).
•
Keep the tires properly inflated and use
only the recommended size.
•
Use the recommended engine oil.
•
Perform all regularly scheduled
maintenance.
Avoid these actions; they reduce your fuel
economy:
•
Sudden accelerations or hard
accelerations.
•
Warm up your vehicle on cold
mornings.
•
Use the air conditioner.
•
Use the speed control in hilly terrain.
•
Rest your foot on the brake pedal while
driving.
•
Carry unnecessary weight.
Approximately 1 mpg [0.4 km/L] is lost
for every 400 lb (180 kg) of weight
carried.
•
Driving with the wheels out of
alignment.
Conditions
•
Adding certain accessories to your
vehicle may reduce fuel economy. For
example bug deflectors, rollbars, light
bars, running boards, ski racks or
luggage racks.
•
Using fuel blended with alcohol may
lower fuel economy.
•
Fuel economy may decrease with lower
temperatures during the first 5–10 mi
(12–16 km) of driving.
•
Driving on flat terrain offers improved
fuel economy as compared to driving
on hilly terrain.
•
Transmissions give their best fuel
economy when operated in the top
cruise gear and with steady pressure
on the gas pedal.
COLD WEATHER
PRECAUTIONS
Note:
Idling in cold weather does not heat
the engine to its normal operating
temperature. Long periods of idling,
especially in cold weather, can cause a
buildup of deposits which can cause engine
damage.
Changing to a lighter grade engine oil also
makes starting easier under these
conditions. Refer to Engine oil
specifications. See
Engine Oil Capacity
and Specification
(page 292).
Diesel fuel is adjusted seasonally for cold
temperatures. Diesel fuel which has not
been properly formulated for the ambient
conditions may gel which can clog the fuel
filters. One indication that the fuel filter(s)
may be clogged is if the engine starts, stalls
after a short time, and then does not
restart. If you have been using biodiesel,
you may need to use a fuel with lower
biodiesel content, try another brand, or
discontinue using biodiesel. Do not use
