Driving economy pg. 56
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:
l 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.
l Whenever possible, avoid
using the car for driving short
distances. This does not allow
the engine to reach normal
operating temperature.
l Drive carefully and avoid
rapid acceleration and hard
braking.
l Do not exceed speed limit.
l Avoid carrying unnecessary
items (extra load) in the car.
l Check tire pressure regularly
l Remove snow tires when
threat of snow or ice has ended.
l Note that roof racks, ski
racks, etc., increase air
resistance and thereby fuel
consumption.
l Avoid using automatic
transmission kick-down feature
unless necessary.
l Avoid using the air
conditioning when it is not
required. When engaged, the
air conditioner's compressor
places places an additional load
on the engine. However, please
note that fuel consumption is
lower with the air conditioning
on than it is when driving with
the air conditioning switched
off and the windows down.
Other factors which decrease
gas mileage are:
l Worn or dirty spark plugs
l Incorrect spark plug gap
l Dirty air cleaner
l Dirty engine oil and clogged
oil filter
l Dragging brakes
l Incorrect front end alignment
