Downloaded from www.Manualslib.com manuals search engine The exit speed is usually posted.
Here are some things you can check before a trip:
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 Leaving on a Long Trip
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.

Windshield Washer Fluid: Is the reservoir full? Are
all windows clean inside and outside?
Wiper Blades: Are they in good shape?
Fuel, Engine Oil, Other Fluids: Have you checked
all levels?
Lamps: Are they all working? Are the lenses clean?
Tires: They are vitally important to a safe,
trouble-free trip.
Is the tread good enough for
long-distance driving? Are the tires all inflated to the
recommended pressure?
Weather Forecasts: What’s the weather outlook
along your route? Should you delay your trip a short
time to avoid a major storm system?
Maps: Do you have up-to-date maps?

Downloaded from www.Manualslib.com manuals search engine Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little faster
than just idle. That is, push the accelerator slightly. This
uses less fuel for the heat that you get and it keeps the
battery charged. You will need a well-charged battery to
restart the vehicle, and possibly for signaling later on
with your headlamps. Let the heater run for a while.
Then, shut the engine
off and close the window almost
all the way to preserve the heat. Start the engine again
and repeat this only when you feel really uncomfortable
from the cold. But do it as little as possible. Preserve the
fuel as long as you can. To help keep warm, you can get
out of the vehicle and do some fairly vigorous exercises
every half hour or
so until help comes.

Two labels on your vehicle show how much weight it
may properly carry. The Tire-Loading Information label
found
on the driver's door tells you the proper size,
speed rating and recommended inflation pressures for
the tires on your vehicle. It also gives you important
information about the number of people that can be in
your vehicle and the total weight that you can carry.
This weight is called the Vehicle Capacity Weight and
includes the weight
of all occupants, cargo and all
options not installed
in the factory.

Downloaded from www.Manualslib.com manuals search engine Checking Coolant
L
The surge tank is located next to the engine block on the
passenger's side of the engine.
The cooling system is under a lot of pressure when it is
hot.
If the CHECK COOLANT LEVEL message
appears on the Driver Information Center (DIC), you
will need to add coolant.
l'brning the surge tank pressure cap when the
engine and radiator are hot can allow steam and
scalding liquids to blow
out and burn you badly.
Never turn
the surge tank pressure cap -- even a
little
-- when the engine and radiator are hot.
When your engine is cold, the coolant level should be
at the
FULL COLD mark, which is 2.5 inches (6.4 cm)
below the base
of the fill neck. Use a flashlight as
necessary to
see into the tank.

If the CHECK COOLANT LEVEL message comes on,
it means you're low on engine coolant.
For more information, see "Check Coolant Level"
message in the Index.

If you’ll be driving at high speeds (e.g., speeds of 100 mph
(160 km/h) or higher), where it is legal, set the cold
inflation pressure to the maximum inflation pressure shown on the
tire sidewall, or to 38 psi (265 kpa),
whichever is lower. See the example below. When you end
this high-speed driving, return to the cold inflation
pressure shown on the Tire-Loading Information label.
Example:
You’ll find maximum load and inflation pressure molded
on the tire’s sidewall, in small letters, near the
rim flange. It will read something like this: Maximum load 690
kg (1521 lbs.) @ 300 Wa (44 psi) Max. Press.
For this example,
you would set the inflation pressure
for high-speed driving at
39 psi (265 kPa).
NOTICE:
Don’t let anyone tell you that underinflation or
overinflation is all right.
It’s not. If your tires
don’t have enough air (underinflation), you can
get the following:
Too much flexing
0 Too much heat
0 Tire overloading
NOTICE: (Continued)
NOTICE: (Continued)
Bad wear
Bad handling
0 Bad fuel economy.
If your tires have too much air (overinflation),
you can get the following:
0 Unusual wear
Bad handling
Rough ride
Needless damage from road hazards.
When to Check
Check your tires once a month or more.
Don’t forget your compact spare tire. It should be at
60 psi (420 kPa).
How to Check
Use a good quality pocket-type gage to check tire
pressure.
You can’t tell if your tires are properly inflated
simply by looking at them. Radial tires may look
properly inflated even when they’re underinflated.
Be sure to put the valve caps back on the valve stems.
They help prevent leaks
by keeping out dirt and moisture.
