Downloaded from www.Manualslib.com manuals search engine A WORD ABOUT ... VEHICLE SAFETY AND THE INI­
TIAL FEDERA~ MOTOR VEHICLE SAFETY STANDARDS
Chevrolet has for many years been a leader in the field
of automotive safety. Almost every advance in design and engineering since the jnception of the industry has contributed
to the safety, reliability and durability of our cars. Continua­
tion of this important and vital trend is exemplified in your
1968 Chevrolet. Important safety advances are designed to
aid in avoiding accidents, and in reducing injuries during the accident and as a result of the accident.
But remember-it takes more than a safe car to avoid
accidents. Observe all traffic laws, make safe driving a habit and maintain your car in top condition.
Your
n!,)w 1968 Chevrolet conformed to all federal motor
vehicle safety standards applicable at time of manufacture.
Effectiveness of these safety features ~an best be continued
through periodic vehicle inspection and regular maintenance .
Th~ initial Federal Motor Vehicle Safety Standards en­compass a number of systems on all passenger cars. To pro­mote better understanding of these standards, listed are those
standards applicable to passenger cars, and the purpose and
scope of each.
Initial
Federal Motor Vehicle Safety Standards (Effective January 1, 1968*)
Amendment to certain of these
Standards and additional Standards that would apply to 1968 Model passenger cars
manufactured after January 1, 1968 , were under cons ideration by the National Highway Safety Bureau at the time this Owner's Manual was prepared. '
STANDARD NO. 101
Control Location and Identification
Purpose and Scope. This standard specifies the requirements
for location and identification of certain controls to facilitate
their selection and ensure their accessibility.
4
STANDARD NO. 102 Transmission Shift Lever Sequence, Starter Interlock, and Transmission Braking Effect Purpose and Scope. This standard specifies the requirements
for the transmission shift lever sequence, a starter interlock, and for a braking effect of automatic transmissions, to requce the likelihood of shifting errors, starter engagement with vehicle in drive position, and to provide supplemental brak­ing at speeds below 25 miles per hour.
STANDARD NO. 103 Windshield Defrosting and Defogging Purpose lind Scope. This standard specifies requirements
for providing vision through the windshield during frosting and fogging conditions.
STANDARD NO. 104 Windshield Wiping and Washing Systems
Purpose and Scope. This standard specifies requirements
for windshi eld wiping and washing systems.
ST ANDARD NO. 105 Hydraulic Service Brake, Emergency Brake, and Parking Brake Systems
Purpose and Scope. This standard specifies requirements
for hydraulic service brake, emergency brake, and parking
brake systems intended to ensure adequate braking per­formance under normal and emergency conditions.
STANDARD NO. 106 Hydraulic Brake Hoses Purpose and Scope. This standard specifies requirements
for hydraulic brake hoses that will reduce brake failures due to fluid leakage.
STANDARD NO. 107 Reflecting Surfaces
Purpose and Scope. This standard specifies reflecting sur­face requir ements for certain vehicle components in the driver's field of view.

gear at any speed below 20 mph.
TO STOP-Release the accelerator and depress the
brake pedal. As car slows down, depress the clutch
pedal and move the gearshift lever into neutral.
NEUTRAL-For use when starting or idling engine.
REVERSE-Operate as for 1 st gear but always at a
slow speed.
CAUTION: When parking or leaving the car unattended,
even for a few minutes, remove the ignition key, place
the selector lever in first gear or reverse if manual trans­
mission, and fully apply the parking brake.
DRIVING WITH THE POWERGLIDE TRANSMISSION
The optional Powerglide transmission is a completely
automatic transmission which replaces the standard clutch
and transmission. After starting the engine with the se­
lector lever
in N (neutral) position, merely select the
range desired and depress the accelerator. The Power­
glide
transmission will do the rest.
Automatic transmission shift
quadrants of all GM
cars continue the uniform sequence of selector positions.
This particularly benefits multicar families and those who
occasionally drive other cars. Shift indicators are ar­
ranged as follows: "Reverse", "Neutral" and the forward
driving
ranges. All automatic transmissions are equipped
with a starter interlock system designed to permit start­
ing the engine only when the transmission selector is in
the "Neutral" position. For additional engine braking
effect,
as sometimes needed in mountainous driving,
place the transmission in an intermediate or low range.
10
The dash-mounted driving range selector is equipped
with mechanical stops to prevent unintentional shifting
into reverse
and low ranges. Move lever to the left, to
override stop,
and continue shift for selection of reverse
or low ranges.
With
lever in 0 position the transmission starts in
automatic low gear and will shift to cruising gear at
some point between approximately 12 and 50 mph,
depending on the accelerator position. Thus, a slow start
with a steady, gradual increase of pressure on the accel­
erator pedal will enable the transmission to shift into the
more economical cruising gear in the shortest possible
time. Hard acceleration for fast starts will cause the trans­
mission to remain in low gear for a considerably longer
period.
When driving at speeds below 45 mph, the transmis-

Downloaded from www.Manualslib.com manuals search engine sion may be shifted into low range for extra acceleration
for passing by depressing the
accelerator pedal fully. The
transmission
will automatically shift back into cruising
gear when the accelerator pedal is momentarily released.
CAUTION: It is important that the parking brake be fully engaged, in addition to removing the ignition key,
when your Corvair is parked or otherwise left unattended. The automatic transmission does not hold the car
regardless
of the position of the selector lever.
Operating Your Powerglide Transmission
POSITION OPERATION USES
R-REVERSE For Backing Car (From Stopped Position)
N-NEUTRAL For Starting Engine (Brakes Applied) NORMAL DRIVING D-DRIVE For all Forward Driving. Step hard on RANGE accelerator for extra acceleration below 45 mph.
L-LOW For Hard Pulling at Low Speeds, Climb-SAND, SNOW, ing, or Descending Steep Grades and for MUD OR ON additional engine braking below 40 mph. STEEP GRADES
Powerglide Driving Cautions
• Always engage parking brake when parked.
• Do not accelerate engine in l, 0, or R with the
brakes
engaged. This can cause damage by
overheating transmission.
• Do not hold car on an upgrade by accelerating

engine. Use brakes.
• Use low position for hard pulls at low speed,
climbing or descending steep grades and for
push starting.
• Always stop car before shifting to reverse.

EMERGENCY STARTING
Your Corvair may be started in an emergency by
pushing. When being pushed to start the engine, turn
off all unnecessary electrical loads, turn the ignition to "ON", and (if manual transmission) depress the
clutch and place the shift lever in high gear or, (if
powerglide) move selector lever to NEUTRAL position.
Release the clutch when car speed reaches 10 to 15 miles per hour (manual transmission); move the selector
lever to LOW position when car speed reaches 20 to
25 miles per hour (powerglidel. Bumpers and other
parts contacted by the pushing vehicle should be pro­
tected from damage while pushing. Never tow the car
to start.
TOWING
Normally your Corvair may be towed with all four
wheels on the ground for distances up to 50 miles at
12
speeds of less than 35 mph. The engine should be off
ahd the transmission in neutral.
However, the drive wheels (rear wheels) must be
raised off the ground or the drive shaft disconnected
when the transmission
is not operating properly or when
a speed
of 35 mph or distance of 50 miles will be exceeded.
CAUTION: If car is towed on its front wheels only, the
steering wheel must
be secured with the wheels in a
straight ahead position .
ROCKING CAR
If it becomes necessary to rock the car to free it
from sand, mud or snow, move the selector lever from "D" to "R" (automatic transmission) or the shift lever
from forward to reverse (manual transmission) in a
repeat pattern while simultaneously applying moderate
pressure to the accelerator. Do not race engine. Avoid
spinning wheels when trying to free the car.

ments
if necessary. Idle adjustment should be performed by your
Chevrolet Dealer.
If the above Fuel System checks and the checks suggested under
the Electrical System following do not correct the malfunction, it is
recommended that you turn to your Authorized Chevrolet Dealer
for further checks, adjustments
or repairs.
ELECTRICAL SYSTEM
If, when the ignition key is turned to START, the engine will not
turn over, you have
good reason to suspect electrical trouble.
(F) When there is no response at all to attempts to start the car,
check the obvious-your AUTOMATIC TRANSMISSION SELECTOR
LEVER must be in neutral position before the engine can be started.
Turning the IGNITION SWITCH rapidly back and forth several
times
will sometimes correct a poor internal switch contact.
(G) The BATTERY may be discharged. If so, lights will be dim and
the horn will have a poor tone if it will blow at all.
Usually
a garage recharge will be necessary to return the battery
to operotion. Occasionally, however, a long drive will recharge
the battery.
NOTE:
If the battery is determined to be dead, and for no apparent
reason, have
your Authorized Chevrolet Dealer check the
battery, the GENERATOR and the
VOLTAGE REGULATOR.
GENERATOR trouble should already have been indicated
by
the indicator on the instrument panel. Never remove generator
"BAT" lead without first disconnecting battery ground cable.
48
POOR BATTERY CONNECTIONS may be suspected if the car has operated properly a short time before and now not even the horn
will operate. Check both ends of both battery cables. If the con­
nections are corroded, a car may sometimes be restored to opera­tion by removing all cable ends, scraping all contacting surfaces
clean with a pen knife, and reassembling. If the cables are broken,
they must be replaced. The power supply should now be restored
unless the battery is dead.
(H) If, however, the lights and horn work properly but the starter will still not turn over, check the STARTER connections. A "click" from the starter solenoid indicates that the wiring to the starter is properly installed. If the wiring seems to be clean and tightly in­stalled, the trouble is probably in the starter itself and should be referred to your Authorized Chevrolet Dealer.
When the engine will "turn over" but will not start, the following
items may be checked along with Fuel System Checks listed previously.
(I) With a clean dry cloth wipe the ceramic portions of the spark plugs dry. In particularly damp or rainy weather dampness may be the cause of not sta rting, especi­ally when the engine is cold.
(J) Check the cables at the top of the distributor and coil as well as each spark plug cable for
tightness.
(K) If the car will still not start, check for spark at the spark plugs in the following manner:
Pull one of the spark plug
wires off its spark plug. Insert a
short piece of bare wire (such as a bobby pin) between the rubber Distributor and Coil Leads
