Before Leaving On A Long Trip; Highway Hypnosis - GMC 2003 Yukon Owner's Manual

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.
Here are some things you can check before a trip:
•
Windshield Washer Fluid: Is the reservoir full? Are
all windows clean inside and outside?
•
Wiper Blades: Are they in good shape?
•
Fuel, Engine Oil, Other Fluids: Have you checked
all levels?
4-44
•
Lamps: Are they all working? Are the lenses clean?
•
Tires: They are vitally important to a safe,
trouble-free trip. Is the tread good enough for
long-distance driving? Are the tires all inflated to the
recommended pressure?
•
Weather Forecasts: What's the weather outlook
along your route? Should you delay your trip a
short time to avoid a major storm system?
•
Maps: Do you have up-to-date maps?

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.
