to produce stereo,
though some do not. (C-QUAM@ is a registered trademark of Motorola, Inc.).
If your Delco@ system can get C-QUAM? your “STEREO” light will come on
when you’re receiving it.

Care of Your Cassette Tape PIayer
A tape player that is not cleaned regularly can cause reduced so\
und quality,
ruined cassettes, or a damaged mechanism. Cassette tapes should be stored
in their cases away from contaminants, direct sunlight, and extreme\
heat.
If
they aren't, they may not operate properly or cause failure of\
the tape player.
Your tape player should be cleaned regularly each month
or after 15 hours of
use. If you notice a reduction in sound quality, try a known good cassette to
see
if the tape or the player is at fault. If this other cassette has no
improvement in sound quality, clean the tape player.
Clean your tape player with a wiping-action, non abrasive clean\
ing cassette,
and follow the directions provided with
it.
Cassettes are subject to wear and the sound quality may degrad\
e over time.
Always make sure that the cassette tape is in good condition \
before you
have your tape player serviced.

Fixed Mast Antenna
The fixed mast antenna can withstand most car washes without being
damaged.
If the mast should ever become slightly bent, you can straighten it
out by hand. If the mast is badly bent, as it might be by vandals, you should
replace
it.
Check every once in a while to be sure the mast is still tightened to the
fender.

Traffic Lights
AM402014
We’re all familiar with traffic lights or stop lights. Often, green arrow\
s are
being used in the lights for improved traffic control. On some multilane road\
s,
green arrows light up, indicating that traffic in one
or more lanes can move or
make a turn. Green arrows don’t mean “go no matter what.\
” You’ll still need
to proceed with caution, yielding the right
of way to pedestrians and
sometimes to other vehicles.
Some traffic lights also use red arrows to signify that you must stop before
turning on red.

- AM40201 5
Many city roads and expressways, and even bridges, use reversib\
le-lane
traffic control during rush
hours. A red X light above a lane means no driving
in that lane at that time.
A green arrow means you may drive in that lane.
Look for the signs posted to warn drivers what hours and days these
systems are in effect.

Pavement Markings
NO PASSING ZONE
AM40201 6
Pavement markings add to traffic signs and signals. They give information to
drivers without taking attention from the roadway. A solid yellow line on your
side
of the road or lane means “don’t cross.”
Your Own Signals
Drivers signal to others, too. It’s not only more polite, it’s safer to let other
drivers know what you are doing. And in some places the law requires driver
signals.
Turn and lane change signals: Always signal when you plan to turn or
change lanes.
If necessary, you can use hand signals out the window: Left arm \
straight out
for a left turn, down for
slow or about-to-stop, and up for a right turn.
Slowing down: If time allows, tap the brake pedal once or twice in advance
of slowing or stopping. This warns the driver behind you.
Disabled: Your four-way flashers signal that your vehicle is disabled or is a
hazard. See “Hazard Warning Flasher” in the Index.
Traffic Officer
The traffic police officer is also a source of important informaaon. The officer’s
signals govern, no matter what the traffic lights or other sig\
ns say.
The next part discusses some of the road conditions you may e\
ncounter.

AM407001
According to the American Medical Association, a 180-pound (82 kg) person
who drinks three 12-ounce
(355 ml) bottles of beer in an hour will end up
with a BAC of about 0.06 percent. The person would reach the same BAC
by drinking three 4-ounce (120 ml) glasses of wine or three mixed drinks
if
each had 1-112 ounces (45 ml) of a liquor like whiskey, gin or vodka.
It’s the amount of alcohol that counts. For example, if the same person drank
three double martinis
(3 ounces or 90 ml of liquor each) within an hour, the
person’s BAC would be close
to 0.12 percent. A person who consumes food
just before or during drinking
will have a slightly lower BAC level.
