Once you are moving on the freeway, make certain you allow a
reasonable following distance. Expect to move slightly slower at night.
When you want
to leave the freeway, move to the proper lane well in
advance.
If you miss your exit do not, under any circumstances, stop and
back up. Drive on to the next exit.
The exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted.
Reduce your speed according to your speedometer, not to your sense of
motion. After driving for any distance at higher speeds, you may tend to
think you are going slower than you actually are.
BEFORE LEAVTNG ONA LONG THP
Make sure you’re ready. Try to be well rested. If you must start when
you’re not fresh
-- such as after a day’s work -- don’t plan to make too
many miles that first part
of the journey. Wear comfortable clothing and
shoes you can easily drive in.
Is your vehicle ready for a long trip? If you keep it serviced and
maintained, it’s ready to
go. If it needs service, have it done before
starting out.
Of course, you’ll find experienced and able service experts in
Cadillac dealerships all across North America. They’ll be ready and
willing to help if
you need it.
Here are some things you can check before a trip:
0 Windshield Washer Fluid: Is the reservoir full? Are all windows clean
inside and outside?
Wiper Blades: Are they in good shape?
0 Fuel, Engine Oil. Other Fluids: Have you checked all levels?
Lights: Are they all working? Are the lenses clean?

4. Stop and have someone pick up and store the chocks.
Engine Cooling When Trailering
Your cooling system may temporarily overheat during severe operating
conditions such as;
Climbing grades steeper than 4% at ambient temperatures above
90” Fahrenheit (32’Celsius) with a loaded vehicle and trailer.
Stopping after high-speed driving.
Idling for long periods in stop and go traffic.
If “ENGINE
HOT A/C COMPRESSOR OFF” message appears on the
Driver Information Center, do not be alarmed. This is a normal function
designed to reduce the load on the engine and cooling system you can
continue to drive your vehicle.
If “ENGINE COOLANT
HOT” message appears on the Driver
Information Center, pull off to the side of
the road as soon as it is safe to
do so. When the vehicle is at a complete stop, shift the transmission
selector to
P (Park) and allow the engine to idle. Do not turn off the
engine or increase engine speed above a normal idle. Within
two or three
minutes the system should cool sufficiently to allow
A/C operation to
resume. At that
time resume driving at a reduced speed. Return to
normal driving after
10 minutes if the “ENGINE COOLANT HOT”
message
is not displayed.
Maintenance when Trailer Towing
Your vehicle will need service more often when you’re pulling a trailer.
See
the Maintenance Schedule for more on this. Things that are
especially important
in trailer operation are automatic transaxle fluid
(don’t overfill), engine oil, belts, cooling system, and brake wear. Each of
these is covered
in this manual, and the Index will help you find them
quickly. If you’re trailering, it’s a good idea to review these sections
before
you start your trip.
Check periodically
to see that all hitch nuts and bolts are tight.

.+- 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

oxygen sensor will be damaged. All
of that means costly repairs that
wouldn’t be covered by your warranty.

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.

Downloaded from www.Manualslib.com manuals search engine To Check Engine Oil
Pull out the dipstick and clean it with a paper towel or cloth, then push it
back in all the way. Remove it again, keeping the tip lower, and check the
level.
When to Add Oil
If the oil is at or below the ADD line, then you’ll need to add some oil.
But you must use the right kind. This section explains what kind of oil to
use.
For crankcase capacity, see “Capacities and Specifications” in the
Index.
NOTICE:
-
Don’t add too much oil. If your engine has so much oil that the
oil level gets above the cross-hatch area that shows the proper
operating range, your engine could be damaged.

Downloaded from www.Manualslib.com manuals search engine To remove, turn the oil fill cap counterclockwise.
Just
fill it enough to put the level somewhere in the proper operating
range. Push the dipstick all the way back in when you’re through.
What Kind of Oil to Use
Beginning midyear 1993, oils of the proper quality for your vehicle will be
identified
with this new “starburst” symbol. The “starburst” symbol
indicates that the oil has been certified by the American Petroleum
Institute
(API), and is preferred for use in your gasoline engine.
You should look for this on the front of the oil container, and use only
oils that display this
new symbol.

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.

Downloaded from www.Manualslib.com manuals search engine If you cannot find oils with the new “starburst” symbol on the front of the
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.
SAE 1OW-30
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.
GM Goodwrench@ oil (in Canada, GM Engine Oil) meets all the
requirements for your vehicle.
