On She Road
Uidess you are the -only driver, it is good
to share the driving task with others.
Limit turns behind
the wheel to about
100 miles (160 km) Or two hours at a
sitting.-Then, either change drivers ar
stop for some rdreshment like coffee,
tea or
soft drinks and some limbering
up.
But do stop and move around. Eat
lightly along the way. Heavier meals
tend to
mdke some people sleepy.
On two-lane highways or
undivided
multilane highways that do not have
controlled .access,.you’ll
wmt to watch
for some situations :not usustlly found
on freeways. Examples: are: stop signs
and signals, shopping tenters with
direct access
to the highway, no passing
zones and school zones, vehicles
turning
le& and- right off the-road,
pedestrians, cyclists, parked vehicles, and even a&&.
Highway Hypnosis
Is thete-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:
4 Make sure your vehicle is well
ventilated,
with a comfortably cool
interior.
Keep your eyes moving. Sca.n the road
ahead and
-to the sides. Check your
rearview mirrors frequently and your
instruments from time to time. This
can help you avoid
a fixed stare.
Wear good sunglasses in bright light.
Glare can cause drowsiness. But
don’t
wear sunglasses at night. They will.
drastically reduce-your,overall.~sion
at the very time you need all the.
seeing power
you have.
If you get sleepy, pull off the road into
a rest, service, &‘parking area and
take a nap, get so.me exercise, or both.
For safety, treat drowsiness on the
highway
as an emergency.
As in any driving situation, keep pace
with traffic and allow adequate
foIlowing distances.

If You’re Stuck: In Sand, Mud,
Ice or Snow
What you don’t want to do when your
vehicle is stuck is to spin your wheels.
The method
known as “rocking” can
rou must use caution. I help you get out when you’re stuck, but
CAUT/UN I
A: If :you let.your :tires. spin -at
high speed.when the ASR
, . ‘OFE warning light is on, or when
“the SERVICE ASR warning light is
‘on, your tires can explode and you
or others could be injured. And,
spinning your tires with either of
these lights on can cause the
automatic transmission
or other
parts of the vehicle to 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 (56 M) as
shown on the speedometer.
Rocking Your Vehicle to Get It Out:
First, turn your steering wheel left and
right. That will clear the area around
your front wheels. You should turn your
ASR system off. Then, shift back and
forth between R (Reverse) and a
forward gear--or if you have a manual
transmission, between 1 or 2 and
R (Reverse)-spinning the wheels as
little as possible. Release the accelerator
pedal while
you shift, and press lightly
on the accelerator pedal when the
transmission is in gear.
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 the Index under
Towing Your Corvette and Acceleration
Slip Regulation (ASR) System.
