pg. 80 Driving economy
Economical driving conserves natural resources  
Better  driving economy may be  obtained  by thinking ahead, avoiding rapid starts and  stops and  adjusting the speed of
your vehicle to immediate traffic  conditions. Observe the following rules:
 Bring the engine to normal operating temperature as soon as possible by driving with a  light foot on the accelerator
pedal for the first few minutes of operation. A cold engine uses more fuel and  is subject to increased wear.
 Whenever possible, avoid using the car for driving short distances. This does not allow the engine to reach normal
operating temperature.
 Drive carefully and  avoid rapid acceleration and  hard braking.
 Do not exceed posted speed limits.
 Avoid carrying unnecessary  items (extra load) in the car.
 Maintain correct tire pressure. Check tire pressure regularly (when tires are cold).
 Remove snow tires when threat of snow or ice has ended.
 Note  that roof racks, ski racks, etc., increase air resistance  and  also fuel consumption.
 Avoid using automatic  transmission kickdown  feature unless necessary.
 Avoid using the air conditioning when it is not required. When engaged, the A/C compressor places an  additional
load on the engine. However, at higher driving speeds, fuel consumption will be  lower with the air conditioning on and
the windows closed than with the air conditioning off and  the windows open.
 Using the onboard trip computer's fuel consumption modes can help you learn how to drive more economically.
Other factors that decrease  gas mileage are:
 Dirty air cleaner
 Dirty engine oil and  clogged oil filter
 Dragging brakes
 Incorrect front  end  alignment
Some of the above mentioned items and  others  are checked at the standard Maintenance Service intervals.
NOTE : Vehicles equipped with automatic  transmissions  should use (D)rive  as often as possible and  avoid using
