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 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.
4-23

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.
A CAUTION:
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.
A CAUTION: 4-
I
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.
0 Know how to go uphill. Drive in the highest gear possible.
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.

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.
1
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°F; OOC) 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.
If you have traction control, keep the system on. It will
improve 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.
If
you don’t have the traction control system, accelerate
gently. Try not
to break the fragile traction. If you
accelerate too fast,
the drive wheels will spin and polish
the surface under the tires even more.
4-26

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 rear edge of 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
nonfactory-installed options.

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.

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.
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 M)) to
save wear on your vehicle’s parts.

Three important considerations have to do with weight:
0 the weight of the trailer,
e 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). But
even that can be too heavy.
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.

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 canying that weight, too. See “Loading Your
Vehicle” in the Index for more information about your
vehicle’s maximum load capacity.
4-33

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
limit for cold tires.
You’ll find these numbers on the Tire
Loading Information label located 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.
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 rear bumper on your vehicle is not intended for
hitches.
Do not attach rental hitches or other
bumper-type hitches
to it. Use only a frame-mounted
hitch that
does not attach to the bumper.
Will you have to make any holes in the body of your
vehicle when you install a trailer hitch?
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.

Safety Chains 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.
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 and do not attach them to the bumper. Always
leave just enough slack
so you can turn with your rig.
And, never allow safety chains to drag on the ground.
Trailer Brakes
Does your trailer have its own brakes? Be sure to read
and follow the instructions for the trailer brakes so
you’ll be able to install, adjust and maintain them properly.
Because you
have anti-lock brakes, do not try to tap into
your vehicle’s brake system.
If you do, both brake
systems won’t work well, or at all. 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.
