Don't invite car theft! An unlocked car with the
key still in the ignition offers both opportunity and temptation.
Remember always to lock ignition,
lock all doors ... TAKE THE KEY!
NOTE: Your 1968 Chevrolet features as standard equipment a buzzer device which
will activate when the driver's door is opened and the key left in the switch. Heed
its
warning-let it also serve to remind you to lock all doors.
The identification number
of your vehicle is located on the instrument panel and is
visible from the outside. It is also stamped prominently on the engine and transmission.
These precautions have been taken
for your protection to aid the apprehension of thieves
and the recovery
of stolen vehicles, engines and transmissions and to serve as a deterrent
to
theft itself.

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. '

IGNITION SWITCH
OPERA ACCESSORIES ONLY DRIVING STARTING ENGINE
START-Used only when
starting engine. When released,
switch returns to ON.
ON-For normal operation after engine has been started.
OFF-Turns off engine and accessories.
ACC-AII accessories routed through the ignition switch
may
be operated with the switch in this position.
Engine will not
start with switch in ACC position
-ignition system is by-passed, permitting battery
power to flow directly to accessories.
To prevent rapid discharge of battery, do not
operate accessories for prolonged periods with
switch
in ACC position.
KEY WARNING SYSTEM
A high percentage of car thefts occur because car
8
doors are left unlocked or the key is not removed from
the ignition switch. Corvairs
are equipped with an anti­
theft key warning system. Failure
to remove the key from
the ignition switch when
in the OFF position will cause a
warning
buzzer to sound when the left door is opened.
STARTING
1. POWERGLIDE-Place control lever in N position.
The
engine will not start with the transmission
in gear.
MANUAL TRANSMISSION-Place gearshift control
lever in neutral, and depress clutch pedal to the
floor.
2. Depress accelerator pedal part way and hold. In
extreme cold weather (O°F. and below), depress
accelerator pedal twice, then hold pedal part
way down during starting .
NOTE: Engine will not start with accelerator ped­
al depressed to floor, except when "flooded."
3. Turn ignition switch to START and release as soon
as
engine starts .
4. "FLOODED" ENGINE-Depress accelerator pedal to
floor
and hold while cranking engine. DO NOT
"PUMP"
ACCELERATOR PEDAL WHEN ENGINE
IS "FLOODED."

Downloaded from www.Manualslib.com manuals search engine WARM-UP
Never race engine or drive at high speeds until
engine has
had a chance to warm up. Driving with
moderate accelerator pedal application will prevent
stalling
and hesitation, especially during cold weather.
Failure
to allow sufficient warm up time can cause un­
necessary wear to engine, axle or transmission parts
because of inadequate lubrication.
DRIVING WITH THE
MANUAL TRANSMISSIONS
The three-speed and optional four-speed trans­
missions are operated in basically the same manner. Shift

patterns differ, of course, as shown in the two illustra­
tions.
1 st
GEAR (LOW)-Depress clutch pedal, shift into 1 st
gear, slowly release clutch pedal while pressing on
accelerator.
As car gains speed, depress clutch pedal,
release accelerator and move gearshift into 2nd gear.
2nd GEAR-Release clutch pedaI and depress accelerator
as above as car gains speed, then, in same manner
as before, move gearshift lever into 3rd gear.
Use second gear at slow speeds (less than 30 mph)
when driving
in stop-and-go traffic, for improved
vehicle performance during acceleration
and when
descending steep hills.
3rd
GEAR (HIGH)-Slowly release clutch pedal and de­
press accelerator pedal. This is the cruising gear for
all normal driving with the
3-speed transmission.
With the
4-speed transmission 3rd gear will provide
more response
and higher performance for driving
in heavy traffic.
4th
GEAR (HIGH-4-speed transmission only)
Shift into 4th
gear in the same manner for normal
cruising with the
4-speed transmission.
NOTE: Whenever the vehicle begins to labor in
any gear, depress the clutch pedal and shift to
the next lower
gear. Both transmissions, being

Downloaded from www.Manualslib.com manuals search engine fully synchronized, may be downshifted into first
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
11
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.

Downloaded from www.Manualslib.com manuals search engine TRANSMISSION OPERATING TIPS
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.

Downloaded from www.Manualslib.com manuals search engine If the system is not functioning properly, a legal hand
signal should be given, since failure to indicate a turn
is considered a moving traffic violation in many states.
Always signal for a turn
at a reasonable distance before actu 'ally making it.
HAZARD WARNING FLASHER
In the event your car is
disabled or you stop for
any reason on the highway,
the
hazard warning system
which flashes all four turn
signals should
be used to
warn
other drivers that your
vehicle
is a traffic hazard.
The system is activated by
pushing
in on the button
located just
below the steer­
ing wheel on the right side
of the steering column. Use this system only when your
vehicle
is a traffic hazard.
FOOT CONTROLS Foot controls consist of the dimmer switch (the op­
eration of which is covered on page 16), the clutch
pedal (manual transmissions only), the brake pedal and
the accelerator pedal.
CLUTCH PEDAL The operation of the clutch pedal has been fully
covered under
"Driving with the Manual Transmissions"
on
page 9. Its operation is the same whether your car
is equipped with the 3-speed or the 4-speed transmission. Excessive
clutch
wear can be caused by letting up the
clutch abruptly
rather than smoothly, and by "riding" the
clutch-that is, letting your foot rest on the clutch pedal
while driving .
CLUTCH ADJUSTMENT
Clutch adjustment should be checked and adjusted
periodically as necessary to compensate for clutch facing
wear. To check, depress pedal.by hand until resistance
is felt. Free travel of pedal should be approximately
one-inch;
if very little or no free play is evident, clutch
adjustment
is required.
BRAKES
The service brake system is designed for braking per­
formance under a wide range of driving conditions
even when the vehicle
is loaded to its full rated vehicle
load. Driving through deep water may affect brake per­
formance. To assure normal operation after being wet­
ted, service brakes must be dried. To dry them quickly,
lightly
apply the brakes while maintaining a slow for"
ward speed with an assured clear distance ahead until
brake performance re'turns to normal.
Brake System Warning Light
The service brake system is designed so that in the
event of a hydraulic fluid leak,
in one-half of the sys­
tem, the other half still provides some braking action.
A dual purpose brake system warning light is
located at the extreme left side of the instrument panel.
When the parking brake is applied and the ignition
