lost for every 400 lb [180 kilogram] of
weight carried).

Conditions
Heavily loading a vehicle or towing a
trailer may reduce fuel economy at any
speed.
Adding certain accessories to your
vehicle (for example bug deflectors,
rollbars, light bars, running boards, ski
racks or luggage racks) may reduce
fuel economy.
To maximize the fuel economy, drive
with the tonneau cover installed (if
equipped).
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.
