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:
e
e
e
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.
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

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 Ion-
511.
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. Coast
...d downhill in NEUTRA- ,.., 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. 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.
e 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 ihe iop oi a hiii, be aieri. There couia
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.

Winter Driving Include an ice scraper, a small brush or broom, a
supply of windshield washer fluid, a rag, some winter
outer clothing, a small shovel, a flashlight, a red cloth
and a couple
of reflective warning triangles. And, if you
will be driving under severe conditions, include a
small bag
of sand, a piece of old carpet or a couple of
burlap bags to help provide traction. Be sure you
properly secure these items in your vehicle.
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.
Here are some tips for winter driving:
Have your vehicle in good shape for winter.
You may want to put winter emergency supplies in
your vehicle.
4-26

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
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. But you can turn the traction system
off
if you ever need to. You should turn the system off
if your vehicle ever gets stuck in sand, mud, ice,
or snow. See If You Are Stuck: In Sand, Mud, Ice or
Snow on page
4-30. Even though your vehicle has
a traction system you’ll want to slow down and adjust
your driving to the road conditions. See
Traction Control
System (TCS) on page
4- 10.
If you don’t have a traction system, accelerate gently.
Try not to break the gentle traction. If you accelerate
too fast, the drive wheels will spin and polish the surface
under the tires even more.
Unless you have the anti-lock braking system, you’ll
want to brake very gently, too. (If you do have anti-lock,
see
Braking on page 4-6. This system improves your
vehicle’s stability when you make a hard stop on a
slipperv road.) Whether you have
the anti-lock braking
system or not, you’ll want to begin stopping sooner than
you would on dry pavement. Without anti-lock brakes,
if you feel your vehicle begin to slide, let up on the
brakes a little. Push the brake pedal down steadily
to
get the most traction you can.
4-27

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.
If You Are Stuck: In Sand, Mud,
Ice or Snow
In order to free your vehicle when it is stuck, you will
need to spin the wheels, but you don’t want to spin your
wheels too fast. The method known as “rocking” can
help you get out when you’re stuck, but you must
use caution.
If you let your tires spin at high spe ~ ~, ~ rey
can explode, and you or others could be
injured. And, the transaxle or other parts
of
the vehicle can overheat. That could cause an
engine compartment fire or other damage.
When you’re stuck, spin the wheels as little as
possible. Don’t spin the wheels above
35 mph
(55 km/h) as shown on the speedometer.
4-30

Notice: Spinning your wheels can destroy parts
of your vehicle as well
as the tires. If you spin the
wheels too fast while shifting your transaxle
back and forth, you can destroy your transaxle.
See “Rocking Your Vehicle
To Get It Out.”
For information about using tire chains on your vehicle,
see
Tire Chains on page 5-67.
Rocking Your Vehicle To Get It Out
First, turn your steering wheel left and right. That will
clear the area around your front wheels.
If your vehicle
has traction control, you should turn your traction
control system
off. See Traction Control System (TCS)
on page 4-10.
Then shift back and forth between
REVERSE (R) and a forward gear, spinning the wheels
as little as possible. Release the accelerator pedal
while you shift, and press lightly on the accelerator pedal
when the transaxle
is in gear. By slowly spinning your
wheels in the forward and reverse directions, you
will cause a rocking motion that may free your vehicle.
If that doesn’t get you out after a few tries, you may
need to be towed out. If you do need to be towed out,
see “Towing Your Vehicle” following.
4-31

Loading Your Vehicle
The CertificationDire 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 the Gross Vehicle
Weight Rating (GVWR). The GVWR includes the
weight of the vehicle, all occupants, fuel and cargo. The
Certificationflire label also tells you the maximum
weights for the front and rear axles, called the 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 e:'"er the front or rear axle.
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, and
it can change the way your vehicle
handles. These could cause you to lose
control and crash.
Also, overloading can
shorten the life of your vehicle.
Notice: Your warranty does not cover parts or
components that fail because
of overloading.

Towiv a Trailer
=mm
If you don’t use the correct equipment and
drive properly, you can lose control when you
pull a trailer. For example, if the trailer is too
heavy, the brakes may not work well
-- or even
at all. You and your passengers could be
seriously injured. Pull a trailer only if you have
followed all the steps
in this section. Ask your
dealer for advice and information about towing
a trailer with your vehicle.
Notice: Pulling a trailer improperly can damage
your vehicle and result
in costly repairs not covered
by your warranty. To pull a trailer correctly, follow
the advice
in this part, and see your dealer for
important information about towing a trailer with
your vehicle. Additional rear axle maintenance
is required for a vehicle used to tow a trailer.
See “Scheduled Maintenance Services” in the Index. Your
vehicle can tow a trailer. 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 section. 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.
