Downloaded from www.Manualslib.com manuals search engine If so, be sure to fuel your vehicle with quality fuel (see
“Fuel”
in the Index). Poor fuel quality will cause your
engine not to run as efficiently as designed.
You may
notice this as stalling after start-up, stalling when you
put the vehicle into gear, misfiring, hesitation on acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause the light
to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at least one
full tank
of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
have your dealer or qualified service center check the
vehicle.
Your dealer has the proper test equipment and
diagnostic tools to fix any mechanical
or electrical
problems that may have developed.
Oil Pressure Light
This light tells you if there
could be a problem with
your engine oil pressure.
The light goes on when you turn your key to
ON or
START. It goes
off once you start your engine. That’s a
check to be sure the light works. If it doesn’t come on,
be sure to have it fixed
so it will be there to warn you if
something goes wrong.
When the light
comes on and stuys on, it means
that oil isn’t flowing through your engine properly.
You
could be low on oil and you might have some other
system problem.

need to ease
off the gas pedal.
message will appear when the engine has overheated. Stop and
turn the engine off immediately to avoid severe engine
damage. See “Engine Overheating” in the Index.
A multiple chime will also sound when this message
is disp1ay.d.
ENGINE POWER REDUCED - 41: This message
informs you that the vehicle is reducing engine power
because the transaxle is being placed in gear under
conditions that may cause damage to the vehicle’s
engine, transaxle or ability to accelerate.
FUEL LEVEL LOW - 11: This message serves as a
warning that the fuel level in the tank is critically low.
Stop for fuel soon.
A single chime will also sound when
this message is displayed.
HEADLAMPS SUGGESTED - 23: If it’s dark enough
outside and the headlamps and twilight sentinel control are
off, a HEADLAMPS SUGGESTED message will display
on the
DIC. This message informs the driver that turning on
the exterior lamps is recommended even though the
DRL are
still illuminated. It has become dark enough outside to
require the headlamps and/or other exterior lamps.
This
message will also appear if the optional rainsense wiping
feature is on and the twilight sentinel is
off.
ENGINE OVERHEATED STOP ENGINE - 42: This
ICE POSSIBLE - 13: This message appears when
the outside air temperature is cold enough to create icy
road conditions.
LEFT REAR DOOR A JAR - 142: The left rear door
is open or ajar when this message appears. The ignition
must be
in the ON position for this message to display.
A chime will also sound when the vehicle’s speed is
greater than
3 mph (4.8 kmh).
OIL PRESSURE LOW STOP ENGINE - 35: If this
message appears while the engine is running, stop the
engine and do not operate it until the cause of low oil
pressure is corrected. Severe damage to the engine can
result.
A multiple chime will also sound when this
message is displayed.
PASSENGER DOOR AJAR - 141: The passenger’s
door
or rear doors are open or ajar when this message
appears. The ignition must be in the
ON position for this
message to display.
A chime will also sound when the
vehicle’s speed
is greater than 3 mph (4.8 km/h).

Downloaded from www.Manualslib.com manuals search engine 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 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,
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?
0 Wiper Blades: Are they in good shape?
0 Fuel, Engine Oil, Other Fluids: Have you checked
all levels?
a
0

0
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?
Highway Hypnosis
Is there actually such a condition as “highway hypnosis”?
Or is it just plain falling asleep at the wheel? Call it
highway hypnosis, lack
of awareness, or whatever.
There is something about
an easy stretch of road with the
same scenery, along with the hum of the tires on the road,
the drone of the engine, and the rush of the wind against
the vehicle that can make you sleepy. Don’t let it happen
to you! If it does, your vehicle can leave the road in
less
than
a second, and you could crash and be injured.
What can you do about highway hypnosis? First, be aware that it can happen.

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 rear edge
of 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 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 kPa (44 psi) Max. Press.
For this example, you would set the inflation pressure
for high-speed driving at
38 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:
4) Too much flexing
4) Too much heat
4) Tire overloading
Bad wear
Bad handling
a Bad fuel economy.
NOTICE: (Continued)
I NOTICE: (Continued)
If your tires have too much air (overinflation),
you can get the following:
Unusual wear
Bad handling
Rough ride
0 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 Pa).
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.
