GMC 1994 Yukon Owner's Manual page 188

Once you are moving on the freeway, make certain you allow a reasonable
following distance. Expect
to
move slightly slower at night.
When you want to leave the freeway, move to the proper lane well in
advance. If you miss your exit do not, under any circumstances, stop and
back up. Drive on to the next exit.
The exit ramp can be curved, sometimes quite sharply.
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 vehicle
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 Wusher 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'?
0
Lights: 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?
Mups: Do you have up-to-date maps?
