HIGmAY HITNOSIS
Is thh 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.
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.

Driving on steep hills or mountains is different from driving in flat or
rolling terrain.
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.

a
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.

monoxide (CO) from your exhaust can get into your vehicle (see
Index under “Carbon Monoxide”). Dirt and water can, too.
NOTICE:
-
The bumpers on your vehicle are not intended for hitches. Do
not attach rental hitches or other bumper-type hitches to them. I-
Safety Chains
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. Follow
the manufacturer’s recommendation for attaching safety chains. Always
leave just enough slack
so you can turn with your rig. And, never allow
safety chains
to drag on the ground.
Trailer 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.
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
so responsive as your vehicle is by
itself.
Before you start, check the trailer hitch and platform, safety chains,
electrical connector, lights, 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.

Downloaded from www.Manualslib.com manuals search engine During your trip, check occasionally to be sure that the load is secure,
and that the lights 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 trailer. 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.
Backing Up
Hold the bottom of the steering wheel with one hand. Then, to move the
trailer to the left, just move that hand to the left. To move the trailer to
the right, move your hand
to the right. Always back up slowly and, if
possible, have someone guide you.
Making Turns
When you’re turning with a trailer, make wider turns than normal. Do
this so your trailer won’t strike soft shoulders, curbs, road signs, trees, or
other objects. Avoid jerky or sudden maneuvers. Signal well in advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have a different turn signal
flasher and extra wiring. The green arrows on your instrument panel will
flash whenever you signal a turn or lane change. Properly hooked up, the
trailer lights will also flash, telling
other drivers you’re about to turn,
change lanes or stop.
When towing
a trailer, the green arrows on your instrument panel will
flash for turns even if the bulbs on the trailer are burned out. Thus, you
may think drivers behind you are seeing your signal when they are not.
It’s important to check occasionally to be sure the trailer bulbs are still
working.

conditions such as;
Climbing grades steeper than 4% at ambient temperatures above

continue to drive your vehicle.
If “ENGINE COOLANT HOT IDLE ENGINE’’ message appears on
the Driver Information Center, pull off to the side of the road as soon as
it is safe to do
so. When the vehicle is at a complete stop, shift the
the engine or increase engine speed above a normal idle. Within
two or
three minutes the system should cool sufficiently to allow A/C operation
normal driving after
10 minutes if the “ENGINE COOLANT HOT

Engine damage from running your engine without coolant isn’t
covered
by your warranty.
If there seems to be no leak, check to see if the electric engine fans are
running.
If the engine is overheating, both fans should be running. If they
aren’t, your vehicle needs service.
How to Add Coolant to the Coolant Surge Tank
If you haven’t found a problem yet, but the coolant level isn’t visible
inside the surge tank add a
50/50 mixture of clean water (preferably
distilled) and a proper antifreeze at the coolant surge tank, but be sure
the cooling system, including the coolant surge tank pressure cap, is cool
before you do it.
(See “Engine Coolant” in the Index for more
information about the proper coolant mix.)
If it isn’t, you may have a leak in the radiator fiose, heater hoses, radiator, -
water pump or somewhere else in the cooling system. -
