THIRD (3): This position is also used for normal
driving, however,
it offers more power and lower fuel
economy than OVERDRIVE
(@).
Here are examples for using THIRD (3 j instead of
OVERDRIVE (@) j:
0 When driving on hilly, winding roads.
0 When towing a trailer. so there is less shifting
between gears.
0 When going down a steep hill.
SECOND (2): This position gives you more power. You
can use SECOND (2) on hills. It can help control your
speed
as you go down steep mountain roads, but then
you would also want to use your brakes off and on.
.__
NOTICE:
Don’t shift into SECOND (2) unless you are going
slower than
65 mph (105 km/h), or you can
damage your engine.
FIRST (1): This position gives you even more power
than SECOND
(2). You can use it on very steep hills,
or in deep snow or mud. (If the shift lever is put in
FIRST (1). the transaxle won’t shift into gear until
the vehicle is
going slowly enough.)
NOTICE:
If your front wheels can’t rotate, don’t try to
drive. This might happen
if you were stuck in
very deep sand or mud or were up against a
solid object. You could damage your transaxle.
Also, if you stop when going uphill, don’t hold
your vehicle there with only the accelerator
pedal. This could cause overheating and damage
the transaxle. Use your brakes
to hold your
vehicle
in position on a hill.

This gage shows the engine
coolant temperature.
If
the gage pointer moves
into the red area, the
engine is too hot.
That reading means the same thing as the warning
light
-- the engine coolant has overheated. The section
“Problems on
the Road” in this manual explains what
to
do. See “Engine Overheating’’ in the Index.
SERVICE
ENGINE
SOON
Your Cadillac is equipped
with a computer which
monitors operation
of the
fuel, ignition and emission
control systems.
This system is called OBD I1 (On-Board
Diagnostics-Second Generation) and
is intended to
assure that emissions are at acceptable levels for the
life
of the vehicle, helping to produce a cleaner
environment. (In Canada. OBD I1 is replaced by
Enhanced Diagnostics.) The
SERVICE ENGINE SOON
light conles on and a chime will sound to indicate that
there is
a problem and service is required. Malfunctions
often will be indicated by the system before any
problem
is apparent. This may prevent more serious
damage to your vehicle. This system is also designed
to assist your service technician in correctly
diagnosing any malfunction.

Hold the bottom of the steering wheel with one hand.
Then,
to move the trailer to the left, just move that hand
to the left. To move the trailer to the right, move your
hand to the right. Always back up
slowly and, if
possible, have someone guide you.
When you tow a trailer, your vehicle may need a
different turn signal flasher and/or extra wiring. Check
with your Cadillac dealer. The green arrows
on your
instrument panel will flash whenever
you signal a turn
or lane change. Properly hooked
up, the trailer lamps
will also flash, telling other drivers you’re about to turn,
change lanes or stop.
When towing
a trailer, the green arrows on your
instrulnent panel will flash for turns even if the bulbs on
the trailer are burned
out. Thus, you may think drivers NOTICE:
Making very sharp turns while trailering could
cause the trailer to come in contact with t,he
vehicle. Your vehicle could be damaged. Avoid

important to check occasionally to be sure the trailer
bulbs are still working.
making very sharp turns while trailering.
Reduce speed and shift to a lower gear before you start
When you’re turning with
a trailer, make wider turns down a long or steep downgrade. If you don’t shift
than normal.
Do this so your trailer won’t strike soft down, you might have to use your brakes so much that

Downloaded from www.Manualslib.com manuals search engine If it isn’t, the coolant level should be indicated by a
CHECK COOLANT LEVEL message on the Driver
Information Center.
If it is, you may have a leak in the
radiator hoses, heater hoses, radiator, water
pump or
somewhere else in the cooling system.
A CAUTION:
Heater and radiator hoses, and other engine
parts, can be very hot. Don’t touch them. If
you
do, you can be burned.
Don’t run the engine
if there is a leak. If you run
the engine, it could
lose all coolant. That could
cause an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.
NOTICE:
Engine damage if you keep running your engine
without coolant isn’t covered by your warranty.
See “Overheated Engine Protection Operating
Mode” in the Index.
If there seems to be no leak, with the engine on, check to
see if the electric engine fans are running. If the engine
is overheating, both fans should be running. If they
aren’t, your vehicle needs service.

The cooling s stem in your vehicle is filled with
DEX-COOL engine coolant. This coolant
is designed
to remain in your vehicle for 5 years or 150,000 miles
(240 000 km), whichever occurs first, if you add only
DEX-COOL" extended
life coolant.
8
The following explains your cooling system and how
to add coolant when it is low. If you have a problem
with engine overheating, see "Engine Overheating"
in the Index.
A 50/50 mixture of water and DEX-COOL"
coolant will:
0 Give freezing protection down to -34°F (-37°C).
c
F
Give boiling protection up to 265°F (129°C).
0 Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as they
should.
NOTICE:
When adding coolant, it is important that you
use only
DEX-COOL@ (silicate-free) coolant.
If coolant other than DEX-COOL@' is added to
the system, premature engine, heater core or
radiator corrosion may result. In addition, the
engine coolant will require change sooner
-- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first. Damage caused by the use
of coolant other than DEX-COOL@ is not
covered
by your new vehicle warranty.
Use a mixture of one-half cEean wccfer (preferably
distilled) and one-half DEX-COOL'" coolant which
won't damage aluminum parts.
If you use this mixture,
you don't need to add anything else.

If you need
more coolant, add the proper DEX-COOL@
coolant mixture at the surge tank, but only when the
engine .is cool.
I A CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts
are hot
enough. Don’t spill coolant
on a hot engine.
When replacing the pressure cap, make sure it is tight.
I NOTICE:
~~~~~~~~~~ ~
The surge tank cap is a 15 psi (105 kPa)
pressure-type cap and must be tightly installed
to
prevent coolant loss and possible engine damage
from overheating. Be sure the arrows
on the cap
line up.
If the surge tank pressure cap needs to be replaced, a
General Motors cap is recommended.
Engine coolant temperature
is controlled by a thermostat
in
the engine coolant system. The thermostat stops the
flow of coolant through the radiator until the coolant
reaches a preset temperature.
If your thermostat needs to be replaced, a General
Motors thermostat
is recommended.
