pg. 64 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 short trips. Short trips do 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 (check 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 thereby fuel consumption.
· Avoid using automatic transmission kickdown feature unless necessary.
· Avoid using the air conditioning when it is not required. When engaged, the air conditioner's compressor 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.
· Utilizing the fuel consumption modes in the Trip Computer can help you "learn" how to drive more economically.
Other factors which decrease gas mileage are:
· Worn or dirty spark plugs
· Incorrect spark plug gap
· 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 : The automatic transmission's ( D)rive position should be used as often as possible to help improve fuel
economy.
WARNING!
It is recommended that tires of the same make and dimensions be used on all four wheels (including the use of
snow tires). Do not use bias ply tires as this will adversely alter vehicle handling characteristics. Maintain correct tire
pressure.
Do not drive with trunk lid open! A warning light in the instrument panel will indicate that the trunk is open.
Poisonous exhaust gases may enter via the open trunk lid. If the trunk lid/tailgate must be kept open for any reason,
proceed as follows:
· Close the windows.
· Set the ventilation system control to air flow to floor, windshield and side windows and blower control to its
highest setting.

Wear indicator
The tires have a so-called "wear indicator" in the form of a number of narrow strips running across or parallel to the
tread. When approx. 1/16" (1.6 mm) is left on the tread, these strips become visible and indicate that the tire should be
replaced.
Tires with less than 1/16" (1.6 mm) tread have a very poor grip in rain or snow.
When replacing worn tires, it is recommended that the tire be identical in type (radial) and size as the one being
replaced. Using a tire of the same make (manufacturer) will prevent alteration of the driving characteristics of the
vehicle.
To improve tire economy:
· Maintain correct tire pressure. See the tire pressure label on the inside of the fuel filler door.
· Drive smoothly: avoid fast starts, hard braking and tire screeching.
· Tire wear increases with speed.
· Correct front wheel alignment is very important.
· Unbalanced wheels impair tire economy and driving comfort.
· If the wheels are rotated, they should be kept on the same side of the car so that they revolve in the same direction as
prior to rotation.
· Hitting curbs or potholes can damage the tires and/or wheels permanently.
Flat spots
All tires become warm during use. After cooling, when the vehicle is parked, the tires have a tendency to distort
slightly, forming flat spots. These flat spots can cause vibrations similar to the vibrations caused by unbalanced wheels.
They do, however, disappear when the tire warms up. The degree to which flat spots form depends on the type of cord
used in the tire. Remember that, in cold weather, it takes longer for the tire to warm up and consequently longer for the
flat spot to disappear.
CAUTION: The car must not be driven with wheels of different dimensions or with a spare tire other than the one that
came with the car. The use of different size wheels can seriously damage your car's transmission.
