Starting the Engine
IGNITION SWITCH
•
The five-position ignition switch allows full control of the electrical systems of your Corvette. To start engine turn the switch to START and release as soon as the engine starts. The switch will r eturn to the ON position and all electrical circuits will be ready for use. Use OFF, LOCK and ACC positio ns to stop the engi ne. The ACC position will anow you to use all accessories without e n ergizi ng the ignition system.

STARTING
PROCEDURES
Place the transmission selector lever in neutral or park position and, on manual transmission equipped models, push the clutch pedal down while starting engine.
Depress the accelerator pedal to the floor and fully release. Turn the ignition switch to START and hold until the engine starts. During temperatures of 0 ° F, and below, and when the engine is hot, the acce lerator pedal should be held part way down while starting. Start a "flooded" engine by holding accelerator pedal to the floor while o'anking engine. CAUTION: Carbon monoxide is a poisonous gas produced by the engine of any ca?'. It is odorless
so you cannot detect its presence. B e safe. Never Sial"t or run YOW" C01"Velte in a closed garage or park with the windows closed and engine operating.

Driving with the Powerg lide Transmission
The optional Powerglide is a completely automatic transmission which replaces the standard clutch and transmission. After starting the engine with the seIce-

POWERGLIDE DRIVING CAUTIONS
• Do not accelerate engine in L, D , 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. •
Do not use Low position except for hard pulls at low
speed or down-hill braking at speeds below
40 MPH.
• Do not shift inw Reverse or Park before coming to a complete stop .
• Always engage
parking brake when parked.

Downshifting with
Manual Transmission
If you wish to shift from one gear to the one imme ­
di ately lower in ratio, avoid dangerous ly overspeed­
ing the engine by downshifting as follows:
I.
Watch the Tachometer-If your tach is orange­
zoned at 5000 to 5300 rpm, you may downshift to
the next lower gear when it indicates 4000 to 4100
rpm. If your tach is red-zoned at 6300 to 6500 rpm, you may downshift to the next lower gear at 4700 to 4900 rpm.
2. Double-clutching reduces strain on engines and transmissions. The usual method of double ­
clutching is:
Let up on the throttle, disengage the clutch, shift
into neutral, and engage the clutch. Almost si­multaneously, speed up the engine, disengage the
clutch, shift into the next lower gear and re­engage the clutch while depressing the throttle.
With practice , this procedure becomes alm ost
second nature.
Driving with Positraction
The positraction rear axle will give you constant
driving force on both rear wheels, especially helpful in the winter and during other slippery driving con­
ditions which might stop a conventionally equipped vehicle. During turns , the positraction axle applies
the major driving force to the inside rear wheel thus
improving stability and cornering. Normal light throttle application will supply maximum traction.
When starting with one rear wheel on an excessive ly
slippery surface, slight application of the
parking brake may be necessary momentarily to gai n maxi­
mum traction.
Driving with
Metallic Brake Linings
If your Corvette is equipped with optional metallic
brake linings, you will find that somewhat mor e than
normal pedal pressure will be required to stop the car
until you have made several stops to warm up the
linings .

Pushing and Towing Tips
PUSHING CAR TO START
Should it ever beco me necessary to start the engine by
pu shing the car (towing to start is not recommended as car being towed may accelerate into tow car), pro­
ceed as fo llows: Turn off all e lect rical loads su ch as radio, heater
and, if possible, lights until the engine st arts.
MANUAL TRANSMISSION - T
urn ignition switch
to "on." Place shift leve r in high (3rd on 3-spee d
transmissions, 4th on four-speed) and depress clutch. When car reaches 25-30 miles per hour, slowly re­
l ease clutch to sta rt e ng ine.
POWERGLlDE TRANSMISSION -
Turn ignit io n
switch to "on" and place sel ector lever in "N." W h e n

A DISABLED CAR
If your Corvette must be towed, the following pre­
cautions must be observed:
MANUAL TRANSMISSION
-Release parking brake
and place shift lever in neutral.
POWERGLIDE TRANSMISSION -Release
parking brake and place selector lever in "N." DO NOT TOW IN EXCESS OF 30 MPH. II the transmission is inoperative, or not operating properly, the pro­peller shaft must b e d isconnected or car must be
towe d with rear wheels off the ground.
TOWING WITH REAR WHEELS
RAISED-When a
vehicle is being towed on its front wheels, the steer­
ing whee l shou ld be secured to maintain a straight
forward position.
Do
not use tire chains on the rear wheels of your Corvette . Clearance between
USE OF TIRE CHAINS
AND SNOW TIRES
• tire and wheelhouse is insufficient to permit operation with chains insta!led.
Many [ire manufa cturers market tires for the Corvette which have specialized
tread designs for mud and snow use.

CLUTCH AND STEERING ADJUSTMENTS-Your Chevrolet deal!!! '?I.n make these 'adjustments for YQu: • A linkage adjustment to reduce clutch pedal travel to permit .fast release and more rapid gear shifting; • An adjustment to move the steering wheel forward or rearward; _ A linkage IIdjustment to permit
"faster" steering
response.
TRAILERS and their EFFECT on CAR OPERATION
The Corvette is designed primaril y (or passenge r
co nveyance . H owever , it is well known that many owners do pull trailers and have experi e nced very
sa tisfacLOry serv ice.
When a trailer is attached to a car, the car becomes
not only a l oad-carrying vehicle, but a load-pulling vehicle . The d e m a n ds of this type of operation are
very different from those (or which t h e automobile is pri ma rily designed and may present probl ems, such
as spring and tire loading, braking, coo ling, lighting, and steering. Howeve r, careful driving practices will
better s atisfy the requirements of trailer hauling.
If in the opinion of the manufacturer a part or com ­ponent of a motor vehicle has been advers ely affected
by misuse of the vehicle with trailer loads, such part or
com
ponent will not be covered by the manufac­turers warranty .
The size o f and equipment for trailers, including
su ch ite ms as hitc hes and safe t y ch a ins, brakes, ligllls, pO\ve r- wei ght ratios a n d over-all length, are gen erally
su bject to safet y regulations in all states, and i t is the responsibility o f the u ser to m a ke certain that h e is in full compliance with th e regulations of the states
in which h e plans to opera te with a traile r and of t h e Interstate Commerce Commission, i f applicable,
before doing so . Furthe r , when opera tin g a car with a traile r attached, the drive r must realize tha t the performance, steering characte ri stics , a n d brakin g distance of his ca r h ave been altered , and that h e mlls t exe r c ise greater caution t o safe ly handle his
ca r and trailer.
