Downloaded from www.Manualslib.com manuals search engine GARAGE DOOR OPENER (OPTION)
This option allows you
to open up to three
garage doors. The
transmitter unit fits the
overhead panel.
Your Cadillac dealer can tell you about the hand held power pack unit
and the installation you’ll need at home to make this work. If your
Cadillac is equipped with an Electriclears heated windshield,
you’ll have
to be closer to the garage door for the transmitter unit to work.
FLOOR MATS
If your Cadillac is equipped with rubber-backed front and rear floor mats,
keep them clean by vacuuming and using a spot cleaner,
if necessary. Do
not machine wash.
TRACTION CONTROL SYSTEM (STS)
Tour traction control system operates only when the system senses that
one or both
of the front wheels is spinning or beginning to lose traction
while driving. This is especially useful
in slippery road conditions. The
traction control system works at all speeds. It limits wheel spin
by using
the antilock and brake systems
to apply the front brakes and by shutting
off furl injectors to reduce engine torque.
You may be able to spin the tires when accelerating from a standstill on
dry
pavement. This is normal. The “Traction Active” message will display on the
drive’s information center when the traction control system is operating.
You may feel the system working through slight movement
of the
accelerator pedal, or you may notice some noise, but this is normal.
Your driver information center is an important source
of information about
your traction control system. See “Driver Information Center” in the Index.

If you’re going uphill
on a one-way street
and you’re parking on
the left side, your
wheels should point to
the right.
.. , . -.
If there is no curb
when you’re parking
uphill, turn the wheels
to the right.
If there is no,curb when you’re parking uphill on the left side
of a
one-way street, your wheels should
be turned to the left.
Torque Lock (Automatic Transaxle)
If you are parking on a hill and you don’t shift your transaxle into “P”
(Park) properly, the weight
of the vehicle may put too much force on the
parking pawl in the transaxle. You may find it difficult to
pull the shift
lever out
of “P” (Park). This is called “torque lock.” To prevent torque
lock, always
be sure to shift into “P” (Park) properly before you leave the
driver’s seat.
To find out how, see “ Shifting Into ’P’ (Park)” in the Index.

Downloaded from www.Manualslib.com manuals search engine If “torque lock” does occur, you may need to have another vehicle pusn
yours a little uphill to take some of the pressure from the transaxle, so
you can pull the shift lever out of “P” (Park).
‘WINTER DmNG
V
Here are some tips for winter driving:
0 Have your Cadillac in good shape for winter. Be sure your engine
coolant
mix is correct.
Snow tires can help in loose snow, but they may give you less traction
on ice than regular tires.
If you do not expect to be driving in deep
snow,
but may have to travel over ice, you may not want to switch to
snow tires at all.
You may want to put winter emergency supplies in your trunk.

rotating the wheel
wrench
counterclockwise.
Tighten the wheel nuts
firmly in a
criss-cross sequence as shown. Lower the jack
completely.
1 A CAUTION:
Incorrect wheel nuts or improperly tightened wheel nuts can
cause the wheel to become loose and even come
off. This could
lead to an accident. Be sure to use the correct wheel nuts.
If you
have to replace them, be sure to get the right kind.
Stop somewhere
as soon as you can and have the nuts tightened
with a torque wrench to 140 Nm (100 ft.lbs.).

GA Performance Blackwall (P225/60ZR 16)
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. Simply looking at the tires
will not tell you the pressure,
especially if you have radial tires
-- which may look properly inflated even
if they’re underinflated.
If your tires have valve caps, be sure to put them back on. They help
prevent leaks
by keeping out dirt and moisture.
Tire Inspection and Rotation
To make your tires last longer, have them inspected and rotated at the
mileages recommended
in the Maintenance Schedule. See “Scheduled
Maintenance Services”
in the Index.
FRONT Use this rotation
pattern.
After the tires have been rotated, adjust the front and rear inflation
pressure as
shown on the Tire-Loading Information label. Make certain
that
all wheel nuts are properly tightened. See “Wheel Nut Torque’’ in the
Index.

Downloaded from www.Manualslib.com manuals search engine This transaxle is the first of a new generation of “SMART” transmissions.
The computer which controls the electronic shift solenoids adapts to
changing environments while you drive. This provides consistent high
quality shifts under all conditions. Communication between the engine
and transaxle through this computer controls engine output during
activation
of torque management or traction control. Smooth shifting is
ensured by design. Hydraulic accumulators control shift pressures and all
shifts are made to free wheeling elements.
The 4T80E uses a
dry sump lubrication system with a scavenger pump.
This unique feature enables the transaxlc to maintain itdcqlriltt!
pressurized oil supply during all mancl~vcr\.

Downloaded from www.Manualslib.com manuals search engine The Hydra-matic 4T60-E 4-speed overdrive, electronic transaxle consists
primarily of a five element torque converter;
two planetary gear sets,
various clutches, final drive assembly, differential assembly, an\
d a control
valve body.
The torque converter houses a pump, turbine, pressure plate which is
splined to the turbine, and a stator assembly, serving as a fluid coupling, it
smoothly transmits power
from the engine to the transaxle. It also
hydraulically provides additional torque
when required. When applied,
the pressure plate provides a mechanical direct drive coupling of the
engine to the transaxle.
The
two planetary gear sets provide the four forward gear ratios and
reverse. Changing of the gear ratios is
fully automatic and is
accomplished through the use
of various electronic and mechanical
requirements. Four multiple disc clutches,
two roller clutches, a sprag
clutch, and three bands provide the friction elements required to obtain
the various ratios with the planetary gear sets.
A hydraulic system (the control valve body), pressurized by a vane type
pump provides the working pressure needed to operate the friction
elements and automatic controls.

Downloaded from www.Manualslib.com manuals search engine The power rack and pinion steering system has a rotary spool valve which
directs hydraulic fluid coming from the power steering pump to one side
or the other side
of the rack piston. The integral rack piston is attached to
the rack. The rack piston converts hydraulic pressure to a linear force
which moves the rack left or right. The force is then transmitted through
the inner and outer tie rods to the steering knuckles, which turn the
wheels
If hydraulic assist
is not available, manual control is maintained. However
under these conditions more steering effort is required.
