There: are two;different fuel economy estimates ,for each vehicle., one for.
city driving
and one for highway driving ... To develop these two .estimates,. ;
separate tests .are used to represent typical everyday city and rural
driving.
The test used to determine the city fuel economy estimate simulates a
7.5 mile (12 km), stop and go trip with. an average speed of 20 mph
(32 km/h). The trip takes 23, minutes and: has 18 stops. About one fifth
of the time is spent idling, as in waiting at traffic lights or in rush hour
traffic.
Two. kinds of engine starts are used: a cold start, which is similar to
starting a car in the morning after it has been parked all night and a hot
start, which is similar to restarting a vehicle after it has been warmed up,
driven and stopped for a short time.

The test used to determine the highway fuel economy estimate represents
a mixture of “non-city” driving. Segments corresponding to different
kinds of rural roads and interstate highways are included. The test
simulates a
10- mile (17 km) trip with an average speed. of 48 mph (77
km/h). The test is run from a hot start and has little idling time and no
stops.
To assure that the fuel economy numbers are most useful for consumers,
the EPA adjusts. these .laboratory test. results. to account for the difference
between controlled laboratory conditions and actual, driving on the road.
The laboratory fuel economy results are adjusted downward
to arrive at
the estimates on the fuel economy window sticker and the
Gas Mileage
Guide. The city estimate is lowered by
10 percent and the highway
estimate is lowered by
22 percent from the laboratory test results.
Experience has proven that these adjustments make the mile:age
estimates-correspond more closely to the actual fuel economy realized
by
the average driver.

Downloaded from www.Manualslib.com manuals search engine Even though these figures are adjusted, they still represent what the
average driver
will get. Your fuel economy may be significantly higher or
lower, depending
on how, when, and where your vehicle is driven. Here
are some things you can do to increase fuel economy;
Combine errands into one trip.
Turn the engine off rather than letting it idle for more than a minute.
Have your Cadillac serviced as described in the maintenance booklet.
Keep tires inflated to recommended pressures.
Anticipate traffic stops.
Here are some things that
will lower fuel economy:
Quick acceleration.
Traveling at higher speeds. Traveling at 65 mph instead of 55 mph
0 Carrying unnecessary weight in the vehicle.
Rewing the engine. This is not necessary for your vehicle.
lowers fuel economy
by 15 percent.
Operating your vehicle with the suspension out of alignment or with
the wheels and tires out of balance.
Use of electrical accessories which require high amperage when they
are not needed.
Even things beyond your control such as weather conditions affe\
ct your
fuel economy. Driving up steep hills, in rain or snow, and into a strong
wind will lower fuel economy. In the lower
left corner of the fuel
economy window sticker from your vehicle is the range
of city and
highway
fuel economy you can expect to get from your Cadillac. If you
are doing everything to raise your fuel economy, but are still not within
this range, your vehicle may need service. Collect as much information
about your
fuel economy as you can find, (miles driven, gallon's of
fuel used, etc.) and provide it to your dealership for their review and
assistance. LA

A "CHECK OIL LEVEL" message will appear when the engine oil is
approximately a quart low. If the message is displayed, check the dipstick
level and add oil as needed.
It's a good idea to check your engine oil every time you get fuel. In order
to get an accurate reading, the oil must be warm and the vehicle must be
on level ground.
Turn off the engine and give the
oil a few minutes to drain back into the
oil pan. If you don't, the oil dipstick might not show the actual level.
