Charge Light
When you turn the key
to “Run,” this light will
come on briefly, to
show that your
alternator and battery
charging systems are
working.
If a light stays on, you need service, and you should take your Cadillac to
the dealer at once.
To save your battery until you get there, turn off all
accessories, and set your Electronic Climate Control system to “OFF.”

Your Fuel Data Center tells you all you want to know about your rue1
situation. Here’s how it works:
This shows
how much fuel you have in
your tank.
“F” means “Full.”
--
“E” means you’re almost empty.
FLASHING
“E” means: stop for fuel
immediately
or you’ll run out.

Downloaded from www.Manualslib.com manuals search engine Your Fuel Data Center has five buttons. Here’s what they do:
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.

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.

Downloaded from www.Manualslib.com manuals search engine Fwc- ta Center
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.
Fan Speeds
m Th e speed of the
blower fan is usually
controlled

have the fan on “Auto
Fan”. However, if you
want the blower fan to
run only at high speed,
push the “Hi” button
until you see “Hi Fan”
on the display.
If you want the blower to run only at low speed, push the “Lo7’ button
until you see
“Lo Fan” on the display. If you want the system to be
automatic, but you like the fan speed a little higher than the “Auto Fan”
speed, push the

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?
