GMC 2007 Acadia - Manual (Page 347)

Keep the windshield and all the glass on your
vehicle clean — inside and out. Glare at night is
made much worse by dirt on the glass. Even the
inside of the glass can build up a film caused
by dust. Dirty glass makes lights dazzle and flash
more than clean glass would, making the pupils
of your eyes contract repeatedly.
Remember that the headlamps light up far less of
a roadway when you are in a turn or curve.
Keep your eyes moving; that way, it is easier to
pick out dimly lighted objects. Just as the
headlamps should be checked regularly for
proper aim, so should your eyes be examined
regularly. Some drivers suffer from night
blindness — the inability to see in dim light — and
are not even aware of it.
Driving in Rain and on Wet Roads
Rain and wet roads can mean driving trouble.
On a wet road, you cannot stop, accelerate, or
turn as well because your vehicle’s tire-to-road
traction is not as good as on dry roads.
