Downloaded from www.Manualslib.com manuals search engine Hydroplaning
Hydroplaning is dangerous. So much water can build up
under your tires that they can actually ride on the water.
This can happen
if the road is wet enough and you’re
going fast enough. When your vehicle is hydroplaning,
it has little
or no contact with the road.
Hydroplaning doesn’t happen often. But it can if your
tires do not have much tread or if the pressure
in one or
more is low. It can happen if a lot of water is standing on
the road.
If you can see reflections from trees, telephone
poles or other vehicles, and raindrops “dimple” the
water’s surface, there could be hydroplaning.
Hydroplaning usually happens at higher speeds. There
just isn’t
a hard and fast rule about hydroplaning. The
best advice
is to slow down when it is raining.
Driving Through Deep Standing Water
NOTICE:
If you drive too quickly through deep puddles or
standing water, water can come in through your
engine’s air intake and badly damage your
engine. Never drive through water that is slightly
lower than the underbody
of your vehicle. If you
can’t avoid deep puddles or standing water, drive
through them very slowly.
Some Other Rainy Weather Tips
0 Besides slowing down, allow some extra following
distance. And be especially careful when you pass
another vehicle. Allow yourself more clear room
ahead, and be prepared to have your view restricted
by road spray.
0 Have good tires with proper tread depth. (See
“Tires” in the Index.)

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.

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?

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.
Then here are some tips:
a
a
a Make sure your vehicle is well ventilated, with a
comfortably cool interior.
Keep your eyes moving. Scan the road ahead and to
the sides. Check your rearview mirrors and your
instruments frequently.
If you get sleepy, pull off the road into a rest, service
or parking area and take a nap, get some exercise, or
both. For safety, treat drowsiness on the highway as
an emergency.
Hill and Mountain Roads
Driving on steep hills or mountains is different from
driving in flat or rolling terrain.
4-24

Downloaded from www.Manualslib.com manuals search engine If you drive regularly in steep country, or if you’re
planning to visit there, here are some tips that can make
your trips safer and more enjoyable.
Keep your vehicle in good shape. Check all fluid
levels and also the brakes, tires, cooling system
and transaxle. These parts can work hard on
mountain roads.
Know how to go down hills. The most important
thing to know is this: let your engine do some
of the
slowing down. Shift to a lower gear when you go
down a steep or long hill.
If you don’t shift down, your brakes could get so
hot that they wouldn’t work well. You would then
have
poor braking or even none going down a hill.
You could crash. Shift down to let your engine
assist vour brakes on a steep downhill slope. Coasting downhill
in
Ir UTRAL (N) or with the
ignition
off is dangerous. Your brakes will have to
do
all the work of slowing down. They could get so
hot that they wouldn’t work well. You would then
have poor braking or even none going down
a hill.
You could crash. Always have your engine running
and your vehicle in gear when you go downhill.

Know how to go uphill. You may want to shift down
to a lower gear. The lower gears help cool your engine
and transaxle, and you can climb the
hill better.
Stay in your own lane when driving on two-lane
roads in hills
or mountains. Don’t swing wide or cut
across the center
of the road. Drive at speeds that let
you stay in your own lane.
As you go over the top of a hill, be alert. There could be
something
in your lane, like a stalled car or an accident.
You may see highway signs on mountains that warn of
special problems. Examples
are long grades, passing or
no-passing zones, a falling rocks area or winding
roads. Be alert to these and take appropriate action.

Downloaded from www.Manualslib.com manuals search engine Driving on Snow or Ice
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 O 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.
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.

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 awhile.
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 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 Your vehicle can tow a trailer if it is equipped with the
proper trailer towing equipment.
To identify what the
vehicle trailering capacity is for your vehicle, you
should read the information in “Weight of the Trailer’’
that appears later in this section. But trailering is
different than just driving your vehicle by itself.
Trailering means changes in handling, durability and
fuel economy. Successful, safe trailering takes correct
equipment, and
it has to be used properly.
That’s the reason for this part. In it are many
time-tested, important trailering tips and safety rules.
Many of these are important for your safety and that of
your passengers.
So please read this section carefully
before you pull a trailer.
Load-pulling components such as
the engine, transaxle,
wheel assemblies and tires are forced to work harder
against the drag of the added weight. The engine is
required to operate at relatively higher speeds and under
greater loads, generating extra heat. What’s more, the
trailer adds considerably to wind resistance, increasing
the pulling requirements.
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, having to do with 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.
Consider using a sway control
if your trailer will
weigh
2,000 lbs. (900 kg) or less. You should always
use a sway control if your trailer will weigh more
than
2,000 lbs. (900 kg). You can ask a hitch dealer
about sway controls.
Don’t tow a trailer at all during the first
1,000 miles
(1
600 km) your new vehicle is driven. Your engine,
axle or other parts could be damaged.
Then, during the first
500 miles (800 km) that you
tow a trailer, don’t drive over
50 mph (80 km/h) and
don’t make starts at full throttle. This helps your
engine and other parts
of your vehicle wear in at the
heavier loads.
Obey speed limit restrictions when towing
a trailer.
Don’t drive faster than the maximum posted speed
for trailers (or no more than
55 mph (90 km/h)) to
save wear on your vehicle’s parts.

Downloaded from www.Manualslib.com manuals search engine Three important considerations have to do with weight:
the weight of the trailer,
the weight of the trailer tongue
and the total weight on your vehicle’s tires.
Weight of the Trailer
How heavy can a trailer safely be?
It depends on how you plan to use your rig.
For
example, speed, altitude, road grades, outside
temperature and how much your vehicle is used to pull a
trailer are all important. And, it can also depend on any
special equipment that you have on your vehicle.
If you have a DeVille or a DeVille d’Elegance without
the optional trailer towing package, the maximum trailer
weight is
1,000 lbs. (450 kg).
If you have a DeVille Concours, DeVille or a DeVille
d’Elegance with the optional trailer towing package, the
maximum trailer weight should never be more than
3,900 lbs.
(1 773 kg) total including the load. But even
that can be too heavy. The
optional trailer towing package provides the
necessary oil cooler for the DeVille or the DeVille
d’Elegance to tow a trailer heavier than
1,000 lbs.
(450 kg). The DeVille Concours is equipped with this
cooler as standard equipment.
The maximum trailer weight for your vehicle can be
determined from the Gross Combined Vehicle Weight
(GCVW). The GCVW
= curb weight + passenger’s
weight
+ cargo weight + trailer weight. The GCVW
should never weigh more than
8,100 lbs. (3 677 kg) total
loaded vehicle and trailer.
