INST (Instantaneous Fuel Economy),
Push this and you’ll see
what
your fuel
economy is at that
instant. The computer
takes
a new reading
twice every second. It
will show economy up
to 70 miles per gallon
(or,
in metric, 2 litres
per
100 kilometers).
I
AVG (Average Fuel Economy),
- This reading is your
average fuel economy
since the last time you
reset the system.
“Avg”
shows total distance
divided by the total
fuel used.

This shows how far the
computer thinks you
can
go with the fuel
that’s in your tank.
When you get down to
40 miles to go (or, in
metric,
64 km) it just
says
“L,” which means
“LOW.” You should
then get fuel right
away.
Your computer needs enough data for the
RANGE reading to work,
however,
so it will read L for a while when your Cadillac is brand new
(under
25 miles). Also, it will show L for a while if your battery has been
disconnected.
FUEL USED

Oil Life Indicator
Your Cadillac has an Oil Life Indicator feature. This tells you when you
need to change your engine oil.
It’s based upon the engine oil
temperatures and your driving patterns.

cl
Press and hold the
Range and Fuel Used
buttons to display the
oil life percentage.
You’ll
see how much oil life you have left, as a percentage. So if you see
“94” for example, that means that the way you’re driving your vehicle,
94%
of your current oil life is still left.
The
“CHANGE OIL SOON” light will come on for a few seconds as a
bulb check when you start your engine. The light will also come on for
20
seconds following engine start-up when either the oil life percentage is
less the
10% or 7,500 miles (12500 km) have been driven. The system
probably will say to change the oil between
3000 miles (5000 km) and
7500 miles (12500 km), but it may even say to change it before 3000 miles
under severe conditions. It all depends on your driving patterns.
(If it
doesn’t,
or if it doesn’t even light up, then something is wrong. You will
need to have it serviced.)
There
are two things the system won’t do: It can’t sense heavy dust in the
places where you drive.
If you drive in a dusty area, you should change
your oil every
3000 miles (5000 km) or 3 months (whichever comes first),
unless the “CHANGE
OIL SOON” light comes on sooner.
It doesn’t check how much oil you have
so you will still have to check for
that.
To check it, see the Index under “Engine Oil.”
When You’ve Changed the Oil
When new oil is put in, you’ll need to reset your system. To do that, press
and hold the “Range” and “Reset” buttons between
5 and 60 seconds.

you may choose
60 F (16 ’ C), for maximum cooling, and 90 F (33 ’ C),
for maximum heating.
Then, you have these choices:
Off
Nothing is on, but air will flow rnrough your vehicle if you are moving.
The system will attempt to maintain the chosen temperature, but may
never reach it, because the blower motor will not operate.
Econ
Use “Econ” in cold or cool weather, because it saves fuel by not allowing
the
A/C compressor to run. But it doesn’t remove humidity from the air.
If it’s so warm outside that you need to cool the air, use the next choice. I 1
Auto
In “Auto” its all automatic.
If your car is sitting out on a hot day and you have it set on “Auto”, the air
LJ
will first flow out the floor air ducts for a few seconds. That’s normal.
This
is to prevent a blast of hot air hitting you.

If you want the blower to run only at low speed, push the “Lo7’ button

warning that you are about to slow down and 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. For example,
40 mph (65 kmh) might seem like only 20 mph
(30 krn/h). Obviously, this could lead to serious trouble on a ramp
designed
for 20 mph (30 km/h)!
DmNG A LONG DISTANCE
Although most long trips today are made on freeways, there are still
many made
on regular highways.
Long-distance driving on freeways and regular highways is the same in
some ways. The trip has to be planned and the vehicle prepared, you
drive at higher-than-city speeds, and there are longer turns behind the
wheel. You’ll enjoy your trip more if you and your vehicle are in good
shape. Here are some tips for a successful long trip.
BEFORE LEAWNG ONA LONG TMP
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:
Windshield Washer Fluid: Is the reservoir full? Are all windows clean
inside and outside?
0 Wiper Blades: Are they in good shape?
Fuel, Engine Oil, Other Fluids: Have you checked all levels?

A CAUTION:
Snow can trap exhaust gases under your vehicle. This can cause
deadly
CO (carbon monoxide) gas to get inside. CO could
overcome you and kill you. You can’t see it or smell it,
so you
might not know it is in your vehicle. Clear
away snow from
around the base of your vehicle
, especially any that is blocking
your exhaust pipe. And check around again from time to time to
be sure snow doesn’t collect there.
Open a window just
a little on the side of the vehicle that’s away
from the wind. This will help keep CO out.
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 headlights. Let
the heater run for awhile.
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.

TOWING A TWLER
I
‘ A CAUTION:
If you don’t use the correct equipment and drive properly, you
can lose control when you pull
a trailer. For example, if the
trailer
is too heavy, the brakes may not work well -- or even at
all. You and your passengers could be seriously injured. Pull a
trailer only if you have followed all the steps in this section.
Your vehicle can tow a trailer.
To identify what the vehicle trailering
capacity is for your vehicle, you should read the information in “Weight
of the Trailer” that appears later in this section. But trailering is different
than just driving your vehicle by itself. Trailering means changes in
handling, durability, and fuel economy. Successful, safe trailering takes
correct equipment, and it has to be used properly.
That’s the reason for this section. In
it are many time-tested, important
trailering tips and safety rules. Many of these are important for your
safety and that
of your passengers. So please read this section carefully
before you pull a trailer.
Load-pulling components such as the engine, transaxle, wheel assemblies,
and tires are forced to work harder against the drag of the added weight.
The engine is required
to operate at relatively higher speeds and under
217

Downloaded from www.Manualslib.com manuals search engine greater loads, generating extra heat. What’s more, the trailer adds
considerably to wind resistance, increasing the pulling requirements.
All of that means changes in:

There are many different laws having to do with trailering. Make sure
your rig will be legal, not only where you live but also where you’ll be
driving.
A good source for this information can be state or provincial
police.
Consider using a sway control.
You can ask a hitch dealer about sway controls.
Don’t tow a trailer at all during the first
500 miles (800 km) your new
vehicle
is driven. Your engine, axle or other parts could be damaged.
Then, during the first
500 miles (800 km) that you tow a trailer, don’t
drive over
50 mph (80 km/h) and don’t make starts at full throttle.
This helps your engine and other parts
of your vehicle wear in at the
heavier loads.
Three important considerations have to do with weight:
1. Weight of the nailer
How heavy can a trailer safely be?
It should never weigh more than
1,000 pounds (453 kg). But even
that can be too heavy.
It depends on how you plan to use your rig. For example, speed,
altitude, road grades, outside temperature and how much your
vehicle is used to pull a trailer are all important. And, it can also
depend on any special equipment that you have
on your vehicle.
You can ask your dealer for our trailering information or advice, or
you can write us at Cadillac.

Doing Your Own Service Work
If you want to do some of your own service wax, you’ll want to get the
proper Cadillac Service Manual. It tells you much more about how to
service your Cadillac than this manual can.
To order the proper service
manual, see “Service Publications” in the Index.
You should keep a record with all parts receipts and list the mileage and
the date
of any service work you perform. See “Maintenance Record” in
the Index.
