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:
0 Make sure your vehicle is well ventilated, with a
comfortably cool interior.
0 Keep your eyes moving. Scan the road ahead and to
the sides. Check your rearview mirrors and your
instruments frequently.
0 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.

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.
0 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.
0 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 your brakes on a steep
downhill slope. Coasting downhill
in NEUTRAL (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 0

to a lower gek The lower gearshelp 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.
c
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 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 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

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
0 and the total weight on your vehicle’s tires.
Weight of the Trailer
How heavy can a trailer safely be?
It should never weigh more than 1,000 lbs. (450 kg) if
you have a DeVille or a DeVille d’Elegance without the optional trailer towing package. If you have a DeVille
Concours, DeVille or DeVille d’Elegance with the
optional trailer towing package, the maximum trailer
weight should never be more than 3,900 lbs.
( 1 773 kg).
These are total maximum weights including the load.
But even that can be too heavy.
If you tow more than 1000 lbs. (450 kg), use trailer
brakes. Be sure to follow the instructions that come with
the trailer or from the brake manufacturer.
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. 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 8,253 lbs. (3
751 kg)
total loaded vehicle and trailer.

Downloaded from www.Manualslib.com manuals search engine Weight of the Trailer Tongue
The tongue load (A) of any trailer is an important
weight to measure because it affects the total
or gross
weight of your vehicle. The
Gross Vehicle Weight
(GVW) includes the curb weight
of the vehicle, any
cargo you may carry in it, and the people who will be
riding in the vehicle. And
if you tow a trailer, you must
add the tongue load to the
GVW because your vehicle
will be carrying that weight, too. See “Loading Your
Vehicle” in the Index for more information about your
vehicle’s maximum load capacity.
A B
If you’re using a weight-carrying hitch, the trailer
tongue
(A) should weigh 10 percent of the total loaded
trailer weight
(B). If you have a weight-distributing
hitch, the trailer tongue (A) should weigh
12 percent of
the total loaded trailer weight (B).
After you’ve loaded your trailer, weigh the trailer and
then the tongue, separately, to see if the weights are
proper.
If they aren’t, you may be able to get them right
simply by moving some items around in the trailer.
Total Weight on Your Vehicle’s Tires
Be sure your vehicle’s tires are inflated to the upper limi\
t
for cold tires. You’ll find these numbers on the
Tire-Loading Information label at the rear edge
of the
driver’s door or
see “Loading Your Vehicle” in the Index.
Then be sure
you don’t go over the GVW limit for your
vehicle, including the weight
of the trailer tongue.

Downloaded from www.Manualslib.com manuals search engine Trailer Wiring Harness
If your vehicle is equipped with the 3,000-lb. (1 360 kg)
trailer towing package option, you will have
a wiring
harness located under the
trunk trim. The harness is a
five-wire harness, with connector.
These trailer-wiring harness color codes should be
followed when connecting it
to your trailer:
WHITE: Direct trailer ground for trailer lamps.
BROWN: Parking lamps.
0 YELLOW Left turn and stoplamps.
GREEN: Right turn and stoplamps.
0 BLUE: Auxiliary circuit.
Driving with a Trailer
Towing a trailer requires a certain amount of experience.
Before setting out for the open road, you’ll want to get
to know your
rig. Acquaint yourself with the feel of
handling and braking with the added weight of the
trailer. And always keep in mind that the vehicle you are driving is now a good deal longer and not nearly as
responsive as your vehicle
is by itself. Before
you start, check the trailer hitch and platform
(and attachments), safety chains, electrical connector,
lamps, tires and mirror adjustment. If the trailer has
electric brakes, start your vehicle
and trailer moving and
then apply the trailer brake controller by hand to be sure
the brakes are working.
This lets you check your
electrical connection at the same time.
During your trip, check occasionally to be sure that the load is secure, and that the lamps and any trailer brakes
are still working.
Following Distance
Stay at least twice as far behind the vehicle ahead as you
would when driving your vehicle without a tr$ler. This
can help you avoid situations that require heavy braking
and sudden turns.
Passing
You’ll need more passing distance up ahead when
you’re towing a trailer. And, because you’re a good deal \
longer, you’ll need to go much farther beyond the
passed vehicle before you can return to your lane.

Towing Your Vehicle
Try to have a GM dealer or a professional towing
service tow your vehicle. See “Roadside Service” in
the Index.
If your vehicle has been changed or modified since it
was factory-new by adding aftermarket items like fog
lamps, aero skirting or special tires and wheels, these
instructions may not be correct.
Before you
do anything, turn on the hazard
warning flashers.
When you call, tell the towing service:
That your vehicle has front-wheel drive.
The make, model and year of your vehicle.
Whether you can still move the shift lever.
If there was an accident, what was damaged.
When the towing service arrives, let the tow operator
know that this manual contains towing instructions and
illustrations. The onerator may want to see them.

Downloaded from www.Manualslib.com manuals search engine If a Tire Goes Flat Changing a Flat Tire
It’s unusual for a tire to “blow out” while you’re driving,
especially if you maintain your tires properly. If air goes
out of a tire, it’s much more likely to leak out slowly.
But if you should ever have a “blowout,” here are a few\

tips about what to expect
and what to do:
If a front tire fails, the flat tire will create a drag that
pulls the vehicle toward that side. Take your foot
off the
accelerator pedal and grip the steering wheel firmly.
Steer to maintain lane position, and then gently brake to
a stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you’d use in a
skid. In any rear blowout, remove your foot from the
accelerator pedal. Get the vehicle under control by
steering the way you want the vehicle to go.
It may be
very bumpy and noisy, but you can still steer. Gently
brake to a stop
-- well off the road if possible.
If a tire goes flat, the next part shows how to use your
jacking equipment to change a flat tire safely. If a tire goes
flat, avoid further tire and wheel damage
by driving slowly to a level place. Turn on your hazard
warning flashers.
Changing
a tire can cause an injury. The vehicle
can slip
off the jack and roll over you or other
people. You and they could be badly injured.
Find
a level place to change your tire. To help
prevent the vehicle from moving:
1. Put the shift lever in PARK (P).
2. Set the parking brake firmly.
3. lhrn off the engine.
To be even more certain the vehicle won’t move,
you can put blocks at the front and rear of the
tire farthest away from the one being changed.
That would be the tire
on the other side of the
vehicle, at the opposite end.
