If you plan on driving in another country outside the U.S. or Canada,
.+- unleaded fuel may be hard to find. Do not use leaded gasoline. If you use
even one tankful, your emission controls won’t work well or at all. With
continuous use, spark plugs can get fouled, the exhaust system can
-- corrode, and your engine oil can deteriorate quickly. Your vehicle’s
oxygen sensor will be damaged. All
of that means costly repairs that
wouldn’t be covered by your warranty.
~ To check on fuel availability, ask an auto club, or contact a major oil
company that does business in the country where you’ll be driving.

The fuel economy estimates are based on results
of tests required by the
U. S. Environmental Protection Agency (EPA). These tests are used to
certify that vehicles meet the Federal emissions and fuel economy
standards. Cadillac tests prototypes of new vehicles and submits the
- results to the EPA. The EPA then confirms the accuracy of the figures
provided by Cadillac. The vehicles are driven by a professional driver
under controlled laboratory conditions, on an instrument similar

identical conditions.
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 adjustment.s make the mileage
estimates correspond more closely to the actual fuel economy realized by
the average driver.
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;
0 Combine errands into one trip.
0 Turn the engine off rather than letting it idle for more than a minute.

0 Keep tires inflated to recommended pressures.
0 Anticipate traffic stops.

Here are some things that will lower fuel economy:
Quick acceleration.
0 Traveling at higher speeds. Traveling at 65 mph instead of 55 mph
Carrying unnecessary weight in the vehicle.
Rewing the engine. This is not ne.cessary for your vehicle.

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.

DO NOT USE SAE 1OW-40, SAE 2OW-50 OR ANY OTHER GRADE OIL NOT RECOMMENDED
As shown in the chart, SAE 1OW-30 is best for your vehicle. However,
you can use
SAE 5W-30 if it's going to be colder than 60 OF (16 C)
before your next oil change. When it's very cold, you should use SAE
5W-30. These numbers on an oil container show its viscosity, or thickness.
Do not use other viscosity oils, such as SAE 1OW-40 or SAE 2OW-50.

container,
you should look for and use oils containing the following three
things:
-
SHor SG
“SH” or “SG” must be-on the oil container, either by itself or
combined with other quality designations, such as
“SH/CD,”
“SH,SG,CD,” “SG/CD,” etc. These letters show American Petroleum
Institute (MI) levels
of quality.

0 Energy Conserving I1
Oils with these words on the container will help you save fuel.
These three things are usually included in a doughnut shaped logo
(symbol) on most containers.
If you cannot find oils with the “starburst”
symbol,
you should look for oils with the doughnut shaped symbol,
containing the three things noted above.
NOTICE:
If you use oils that do not have either the “starburst” symbol or
an
API SH or SG designation, you can cause engine damage not
covered by your warranty.
