Braking in Emergencies
Use your anti-lock braking system when you need to. With anti-lock, you
can steer and brake at the same time. In many emergencies, steering can
help you more than even the very best braking.

Power Steering
If you lose power steering assist because the engine stops or the system is
not functioning, you can steer but it
will take much more effort.
Steering Tips
Driving on Curves
It’s important to take curves at a reasonable speed.
A lot of the “driver lost control’’ accidents mentioned on the news
happen on curves. Here’s why:
Experienced driver or beginner, each of us is subject to the same laws of
physics when driving on curves. The traction of the tires against the road
surface makes it possible for the vehicle to change its path when you turn
the front wheels.
If there’s no traction, inertia will keep the vehicle going
in the same direction. If you’ve ever tried to steer a vehicle on wet ice,
you’ll understand this.
The traction you can get in a curve depends on the condition of your tires
and the road surface, the angle at which the curve is banked, and your
speed. While you’re in a curve, speed is the one factor you can control.
Suppose you’re steering through a sharp curve. Then you suddenly
accelerate. Both control systems
-- steering and acceleration -- have to do
their work where the tires meet the road. Adding the sudden acceleration
can demand too much of those places. You can lose control.
Suppose you’re steering through a sharp curve. Then you suddenly
accelerate. Both control systems
-- steering and acceleration -- have to do
their work where the tires meet the road. Unless your traction control
179

system is on, adding the sudden acceleration can demand too much of
those places. You can lose control.
What should you do if this ever happens? Ease up on the accelerator
pedal, steer the vehicle the way you want it to go, and slow down.
Speed limit signs near curves warn that you should adjust your speed.
Of
course, the posted speeds are based on good weather and road
conditions. Under less favorable conditions you’ll want to go slower.
If you need to reduce your speed as you approach a curve, do it before
you enter the curve, while your front wheels are straight ahead.
Try to adjust your speed so you can “drive’’ through the curve. Maintain a
reasonable, steady speed. Wait to accelerate until you are out of the
curve, and then accelerate gently into the straightaway.
Steering in Emergencies
There are times when steering can be more effective than braking. For
example, you come over a hill and find a truck stopped in your lane, or a
car suddenly pulls out from nowhere, or
a child darts out from between
parked cars and stops right in front
of you. You can avoid these problems
by braking
-- if you can stop in time. But sometimes you can’t; there isn’t
room. That’s the time for evasive action
-- steering around the problem.
Your Cadillac can perform very
well in emergencies like these. First apply
your brakes. It is better to remove as much speed as you can from a
possible collision. Then steer around the problem, to the left
or right
depending on the space available.
An emergency like this requires close attention and a quick decision. If
you are holding the steering wheel at the recommended 9 and 3 o’clock
positions, you can turn it
a full 180 degrees very quickly without removing
either hand. But you have to act fast, steer quickly, and just as quickly
straighten the wheel once you have avoided the object.

LOSS OF CONTROL
Let’s review what driving experts say about what happens when the three
control systems (brakes, steering and acceleration) don’t have enough
friction where the tires meet the road to do what the driver has asked.
In any emergency, don’t give up. Keep trying to steer and constantly seek
an escape route or area of less danger.
Skidding
In a skid, a driver can lose control of the vehicle. Defensive drivers avoid
most skids by taking reasonable care suited to existing conditions, and by
not “overdriving” those conditions. But skids are always possible.
The three types of skids correspond to your Cadillac’s three control
systems. In the braking skid your wheels aren’t rolling. In the steering
or
cornering skid, too much speed or steering in a curve causes tires to slip
and lose cornering force. And in the acceleration skid too much throttle
causes the driving wheels to spin.
A cornering
skid is best handled by easing your foot off the accelerator
pedal.
Remember: Any traction control system helps avoid only the acceleration
skid.
If your traction control system is off, then an acceleration skid is also best
handled by easing your foot off the accelerator pedal.
If your vehicle starts to slide, ease your foot
off the accelerator pedal and
quickly steer the way you want the vehicle to go. If you start steering
quickly enough, your vehicle may straighten out. Always be ready for a
second skid
if it occurs.
Of course, traction is reduced when water, snow, ice, gravel, or other
material is on the road. For safety, you’ll want to slow down and adjust
your driving to these conditions. It is important to slow down on slippery
surfaces because stopping distance will be longer and vehicle control
more limited.
While driving on a surface with reduced traction, try your best to avoid
sudden steering, acceleration, or braking (including engine braking by
shifting to a lower gear). Any sudden changes could cause the tires to

Most of the time, those places where your tires meet the road probably
have good traction.
However, if there is snow or ice between your tires and the road,
you can
have a
very slippery situation. You’ll have a lot less traction or “grip” and
will need to be very careful.
What’s the worst time for this? “Wet ice.”’Very cold snow or ice can be
slick and .hard to drive
on. But wet ice can be even more trouble because
it may offer the least traction of all. You can get “wet ice”
when it’s about
freezing
(32 OF; 0 * C) and freezing rain begins to fall. Try to .avoid driving
on wet ice until salt and sand crews can get there.
Whatever the condition
-- smooth ice, packed, blowing or loose snow --
drive with caution.
1 Keep your traction control system on. It improves your ability to
accelerate when driving on a slippery road. Even though your vehicle has
a traction control system, you’ll want to slow down and adjust your
driving to the road conditions. See “Traction Control System’’ in the
Index.
l
Your anti-lock, brakes improve your ability to make a hard stop on a
slippery road. Even though you have the anti-lock braking system, you’ll
.want to begin stopping sooner than you would on dry pavement. See
“Anti-lock”
in the Index.
Allow greater following distance on any slippery road.
Watch for slippery spots. The road might be fine until you hit a spot
that’s covered with ice.. On an otherwise clear road, ice patches may
appear in shaded areas where the sun can’t reach: around clumps
of
trees, behind buildings, or under bridges. Sometimes the surface of a
curve or an overpass may remain icy when the surrounding roads are
clear.
If you see a patch of ice ahead of you; brake before you are on
it. Try not to brake while you’re actually on the ice, and avoid sudden
steering maneuvers.

If You Do Decide To Pull A Trailer
If you do, here are some important points.
There are many different laws including speed limit restrictions which
apply to 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.
You should always use a load equalizing hitch if your trailer will weigh
more than
2,000 pounds (900 kg). Consider using sway control if your
loaded trailer will weigh
2,000 pounds (900 kg) or less. If your loaded
trailer will weigh
2,000 pounds (900 kg.) or more you should use both
load equalizing hitch and sway control.
NOTICE:
Do not use sway control devices on trailers equipped with surge
brakes, i.e. boat trailers. Surge brakes
do not function properly
when used with most sway control devices.
Don’t tow a trailer during the first 1000 miles (1600 km) your new
vehicle is driven. The engine, axle or other parts could be damaged.
5 During the first 1,000 miles (1600 km) that you tow a trailer, don’t
drive over
50 mph (80 km/h) and avoid full throttle starts. This helps
the engine and other parts
of your vehicle wear in at the heavier loads.
Avoid continuous operation in mountainous areas that have grades
greater than
2% for longer than 5 miles.
A maximum highway speed to 55 mph (90 km/h) when trailering will
enhance the long term durability of your vehicle.
Change axle lubricant annually or every 7,500 miles (12,500 km) of
trailer towing, whichever occurs first.

r Hitches
It’s important to have the correct hitch equipment. Crosswinds, large
trucks going by, and rough roads are a few reasons
why you need the right
hitch. Here are some rules to follow:
If you pull a fully loaded trailer that will weigh more than 2,000
pounds
(900 kg), be sure to use a properly mounted,
weight-distributing hitch and sway control of the proper size. This
equipment is very important for proper vehicle loading and good
handling when you’re driving.
Will you have to make any holes in the body of your vehicle when you
install a trailer hitch?
If you do, be sure to seal the holes to prevent
deadly carbon monoxide (CO) from your exhaust from entering into
your vehicle (see Index under “Carbon Monoxide”).
Don’t let the steel in a hitch contact the aluminum on your bumper. If
you do, the
two will corrode. You can use a insulator such as paint or
plastic tape to separate the steel and aluminum. The same steel to
aluminum corrosion can happen with fasteners, too.
Using A Dead Weight Trailer Hitch
The trailer tongue should weigh 10% of the total trailer load
(maximum 300
lbs.) or as specified by the trailer manufacturer to
minimize sway.
Trailer brakes of adequate size are required on trailers over 1,000 lbs.
(450 kg) loaded weight.
0 If the trailer is over 5,000 lbs. (2270 kg) adjust vehicle rear tire
pressure to (35 psi cold tire pressure).

NOTICE:
Surge brakes do not function properly if used with most
equalizer hitches.

Trailer Hitching Procedure Using A Weight
Distributing (Equalizing) Hitch
(Recommended for loaded trailers weighing 3,000 lbs. to 7,000 lbs.)
Your vehicle is equipped with an Electronic Level Control (ELC) feature.
When hooking up a trailer using a weight distributing hitch, always use
the following procedure:

Place the vehicle on a level surface without the trailer hitched. With
the ignition off, and all doors closed, allow the vehicle to level
automatically.
Disable the Electronic Level Control (ELC) by pulling
MAXI@
fuse #9 (30 AMP) from the underhood electrical center located on
the passenger side wheel housing in the engine compartment. Remove
the cover to gain access.
Attach the trailer to the vehicle. The trailer tongue should weight
12%
of the total loaded trailer weight.
Level the vehicle with the load leveling spring bars (equalizers).
Leave the fuse out while towing your trailer.

NOTICE:
Adjusting an equalizing hitch with the Electronic Level Control \
(ELC) system engaged will defeat the function of the load
equalizing hitch and may cause unsatisfactory handling.
Once you have completed towing your trailer, be sure to reinstall the
Electronic Level Control (ELC) fuse.
In Addition
Use two friction sway controls if your trailer is over 5,000 lbs. .(2270
kg) loaded weight, and/or is. over 24'. long..
0 Use at least one friction sway control if your trailer is over 2,000 lbs.
(908 kg) loaded weight, and consider using one for trailers under
2,000 lbs. (908 kg).

NOTICE:
Do not use sway control devices on trailers equipped with surge
brakes, i.e. boat trailers. Surge brakes do not function proper\
ly
when used with most sway control devices.
0 Trailer brakes of adequate size are recommended on trailers over
1,000 lbs loaded weight.
If trailer is over 5,000 lbs. (2270 kg), adjust vehicle rear tire pressure
to (35 psi. cold tire pressure).
Use a Reese custom made weight distributing hitch or the equivalent
for your Cadillac Fleetwood. (Reese product part number 36042)
Safety Chains
You should always attach chains between your vehicle and your trailer.
Cross the safety chains under the. tongue of the trailer
so that the
tongue will not drop to the road
if it becomes separated from the hitch.
Instructions about safety chains may be provided by the hitch
manufacturer or by the trailer manufacturer. Follow the manufacturer’s
recommendation for attaching safety chains. Always leave just enough
slack
so you can turn with your rig. And, never allow safety chains to drag
on the ground.
Trailer Brakes
If your trailer weighs more than 1,000 pounds (450 kg) loaded, it needs to
be equipped with adequate brakes. Be sure to read and follow the
instructions for the trailer brakes
so you’ll be able to maintain them
properly.
Because you have anti-lock brakes, don’t try to tap into your vehicle
hydraulic brake system. If you do, both brake systems won’t work well, or
at all.
207

Engine Cooling When Trailering
Your cooling system may temporarily overheat during severe operating
conditions such as;
Climbing grades steeper than 4% at ambient temperatures above
90’Fahrenheit (32O Celsius)
with a loaded vehicle and trailer.
0 Stopping after high-speed driving.
0 Idling for long periods in stop and go traffic.
If the “TEMP” warning light comes on, pull
to the side of the road as
soon as it is safe to do
so. When the vehicle is at a complete stop, shift the
transmission selector to P (Park) and allow the engine to idle. If your
Electronic Climate Control system is on, shut it
off. Do not turn off the
engine or increase engine speed above a normal idle. Within
two or three
minutes the system should cool sufficiently to allow A/C operation to
resume. At that time resume driving at a reduced speed. Return to
normal driving after
10 minutes if the “TEMP” warning light is not
displayed.
Maintenance when Trailer Towing
Your vehicle will need service more often when you’re pulling a trailer.
See the Maintenance Schedule for details. Things that are especially
important in trailer operation are automatic transmission fluid (don’t
overfill), engine oil, axle lubricant, engine drive belt, cooling system, and
brake adjustment. Each of these is covered in this manual. The Index will
help you find them quickly. If you’re trailering, it’s a good idea to review
these sections before you start your trip.
Check periodically to
see that all hitch attaching nuts and bolts are tight.
