The exit speed is usually posted.
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 GM
dealerships all across North America. They’ll be ready
and willing to help if you need
it.

Highway Hypnosis
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:
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 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.

The Certificationmire label is found on the rear edge of
the driver’s door. The label shows the size of your
original tires and the inflation pressures needed to obtain
the gross weight capacity
of your vehicle. This is called
GVWR (Gross Vehicle Weight Rating). The GVWR
includes the weight
of the vehicle, all occupants, fuel
and cargo. The
Certificationrnire label also tells
you the maximum
weights for the front and rear axles, called Gross Axle
Weight Rating (GAWR). To find
out the actual loads on
your front and rear axles, you need to go to a weigh
station and weigh your vehicle. Your dealer can help
you with this. Be sure to spread out your load equally on
both sides of the centerline.
Never exceed the GVWR for your vehicle, or the
GAWR for either the front or rear axle.
And,
if you do have a heavy load, you should spread
it out.

Do not load your vehicle any heavier than the
GVWR, or either the maximum front or rear
GAWR. If
you do, parts on your vehicle can break,
or it can change the way your vehicle handles.
These could cause you
to lose control. Also,
overloading can shorten the life of your vehicle.

Total Weight on Your Vehicle’s Tires
Be sure your vehicle’s tires are inflated to the upper
limit for cold tires. You’ll find these numbers on the
Certification label at the rear edge of the driver’s door or
see “Tire Loading” in
the Index. Then be sure you don’t
go over the
GVW limit for your vehicle, including the
weight of the trailer tongue.
Hitches
It’s important to have the correct hitch equipment.
Crosswinds, large trucks going by and rough roads are
a
few reasons why you’ll need the right hitch. Here are
some rules to follow:
The bumpers on your vehicle are not intended for
hitches.
Do not attach rental hitches or other
bumper-type hitches to them. Use only
a
frame-mounted hitch that does not attach to the
bumper. Do not use a ball hitch, because it could pull
the bumper loose.
If you’ll be pulling a trailer that, when loaded, will
weigh more than
4,000 lbs. (1 800 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’re using the wiring provided by the
factory-installed hitch, you should not need to make
any holes in the body
of your vehicle. However, if
you have an aftermarket hitch installed, you may
need to make holes in
the body.
If you do, then be sure to seal the holes later when
you remove the hitch. If you don’t seal them, deadly
carbon monoxide
(CO) from your exhaust can get
into your vehicle (see “Carbon Monoxide”
in the
Index). Dirt and water can, too.

Engine Fan Noise If a Tire Goes Flat
Your vehicle has a clutched engine cooling fan. When the
clutch is engaged,
the fan spins faster to provide more air
to cool the engine. In most everyday driving conditions,
the fan is spinning slower and
the clutch is not fully
engaged. This improves
fuel economy and reduces fan
noise. Under heavy vehicle loading, trailer towing andor
high outside temperatures,
the fan speed increases as the
clutch more fully engages.
So you may hear an increase in
fan noise. This is normal and should not
be mistaken as
the transmission slipping or making extra shifts. It is
merely the cooling system functioning properly. The fan
will slow down when additional cooling
is not required
and the clutch partially disengages.
You may also hear this fan noise when you start
the engine. It will go away as
the fan clutch
partially disengages. 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.

Changing a Flat Tire
If a tire goes flat, avoid further tire and wheel damage
by driving slowly to a level place.
Turn on your hazard
warning flashers.
-
CAUTION:
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. Set the parking brake firmly.
2. Put the shift lever in PARK (P).
3. Turn 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. The
following steps will tell you how to use the
jack and
change a tire.

Removing the Spare Tire and Tools
Your spare tire is stored underneath the rear of your
vehicle.
You will use the ratchet and extension to lower
the spare tire.
A flat rear tire reduces clearance to remove the spare
tire.
If there is less than 12 inches (30.48 cm) between
the ground and the rear bumper or any trailer hitch, jack
up the vehicle until the flat tire is off the ground. (See
“Removing the Flat Tire” and “Installing the Spare
Tire,” Steps
4 through 8, in this section.) Unless your vehicle has
a flat rear tire, do not remove
or restore a tire fromho
a storage position under the
vehicle while the vehicle is supported by a jack. Always
tighten
the tire fully against the underside of the vehicle
when restoring.
If you have a vehicle which was completed from a cab
and chassis, refer to the information from the body
supplierhnstaller.
The spare tire is a
full size tire, like the other tires on
your vehicle.
Remove the retaining wing bolt and lift it off the
mounting bracket. Set the jack and jacking equipment
near the flat tire.
5-23
ProCarManuals.com

For vans with the 15-passenger seating arrangement,
the jack
is secured on the rear passenger side floor of
the vehicle.
Remove the retaining wing bolt and lift it out
of the
mounting bracket. Set the jack and jacking equipment
near
the flat tire.
I
The ratchet has a DOWN side and an UP side.
Attach the ratchet, with
the DOWN side facing you, to
the extension. The extension has a socket end and a flat
chisel end.
Put the flat end
of the extension on an angle through the
hole in the rear door frame, above the bumper. Be sure
the flat end connects into the hoist shaft.
