160 Driving and Operating
Rocking the Vehicle to Get
it Out
Turn the steering wheel left and
right to clear the area around the
front wheels. Turn off any traction
system. Shift back and forth
between R (Reverse) and a low
forward gear, spinning the wheels
as little as possible. To prevent
transmission wear, wait until the
wheels stop spinning before shifting
gears. Release the accelerator
pedal while shifting, and press
lightly on the accelerator pedal
when the transmission is in gear.
Slowly spinning the wheels in the
forward and reverse directions
causes a rocking motion that could
free the vehicle. If that does not get
the vehicle out after a few tries, it
may need to be towed out. If the
vehicle does need to be towed out,
seeTowing the Vehicle 0271.
Vehicle Load Limits
It is very important to know how
much weight the vehicle can
carry. This weight is called the
vehicle capacity weight and includes the weight of all
occupants, cargo, and all
nonfactory-installed options.
Two labels on the vehicle may
show how much weight it may
properly carry: the Tire and
Loading Information label and
the Certification label.
{Warning
Do not load the vehicle any
heavier than the Gross
Vehicle Weight Rating
(GVWR), or either the
maximum front or rear Gross
Axle Weight Rating (GAWR).
This can cause systems to
break and change the way the
vehicle handles. This could
cause loss of control and a
crash. Overloading can also
reduce stopping distance,
damage the tires, and shorten
the life of the vehicle.
Tire and Loading Information
Label
Label Example
A vehicle-specific Tire and
Loading Information label is
attached to the center pillar
(B-pillar). This label shows the
number of occupant seating
positions (1), and the maximum
vehicle capacity weight (2) in
kilograms and pounds.
The Tire and Loading
Information label also shows the
size of the original equipment
tires (3) and the recommended

12470550) - 2020 - CRC - 4/23/20
Driving and Operating 161
cold tire inflation pressures (4).
For more information on tires
and inflation seeTires0245
and
Tire Pressure 0253.
There is also important loading
information on the vehicle
Certification label. It may show
the Gross Vehicle Weight
Rating (GVWR) and the Gross
Axle Weight Rating (GAWR) for
the front and rear axle. See
“Certification Label” later in this
section.
Steps for Determining Correct
Load Limit–
1.
Locate the statement "The
combined weight of
occupants and cargo should
never exceed XXX kg or
XXX lbs." on your vehicle’s
placard.
2.Determine the combined
weight of the driver and
passengers that will be
riding in your vehicle.
3.Subtract the combined
weight of the driver and
passengers from XXX kg or
XXX lbs.
4.The resulting figure equals
the available amount of
cargo and luggage load
capacity. For example, if the
"XXX" amount equals
1400 lbs. and there will be
five 150 lb passengers in
your vehicle, the amount of
available cargo and luggage
load capacity is 650 lbs.
(1400-750 (5 x 150) =
650 lbs.)
5.Determine the combined
weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely
exceed the available cargo
and luggage load capacity
calculated in Step 4.
6.If your vehicle will be towing
a trailer, load from your
trailer will be transferred to your vehicle. Consult this
manual to determine how
this reduces the available
cargo and luggage load
capacity of your vehicle.”
This vehicle is neither designed
nor intended to tow a trailer.
Example 1
1. Vehicle Capacity Weight for Example 1 = 181 kg
(400 lbs)
2. Subtract Occupant Weight @ 68 kg (150 lbs) × 1 =
68 kg (150 lbs)

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
12470550) - 2020 - CRC - 4/23/20
162 Driving and Operating
3. Available Occupant andCargo Weight = 113 kg
(250 lbs)
Example 2
1. Vehicle Capacity Weight forExample 2 = 181 kg
(400 lbs)
2. Subtract Occupant Weight @ 68 kg (150 lbs) × 2 =
136 kg (300 lbs)
3. Available Cargo Weight = 45 kg (100 lbs)
Example 3
1. Vehicle Capacity Weight forExample 3 = 181 kg
(400 lbs)
2. Subtract Occupant Weight @ 91 kg (200 lbs) × 2 =
181 kg (400 lbs)
3. Available Cargo Weight = 0 kg (0 lbs)
Refer to the vehicle's Tire and
Loading Information label for
specific information about the
vehicle's capacity weight and
seating positions. The combined weight of the driver, passengers
and cargo should never exceed
the vehicle's capacity weight.
Certification Label
A vehicle-specific Certification
label is attached to the rear
edge of the driver door. It may
show the gross weight capacity
of the vehicle, called the Gross
Vehicle Weight Rating (GVWR).
The GVWR includes the weight
of the vehicle, all occupants, fuel
and cargo.

something inside the
vehicle, secure it
whenever you can.
Starting and
Operating
New Vehicle Break-In
Follow these recommended
guidelines during the first 2 414 km
(1,500 mi) of driving this vehicle.
Parts have a break-in period and
performance will be better in the
long run.
During the first 800 km (500 mi),
engine torque will be limited in low
gears.
For the first 322 km (200 mi):
. To break in new tires, drive at
moderate speeds and avoid hard
cornering.
. New brake linings also need a
break-in period. Avoid making
hard stops. This is
recommended every time brake
linings are replaced.
For the first 800 km (500 mi):
. Avoid full throttle starts and
abrupt stops.
. Do not exceed 4000 rpm.

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
12470550) - 2020 - CRC - 4/23/20
164 Driving and Operating
.Avoid driving at any one
constant speed, fast or slow,
including the use of cruise
control.
. Avoid downshifting to brake or
slow the vehicle when the
engine speed will exceed
4000 rpm.
. Do not let the engine labor.
Never lug the engine. This rule
applies at all times, not just
during the break-in period.
For the first 2 414 km (1,500 mi):
. Do not participate in track
events, sport driving schools,
or similar activities.
. Check engine oil with every
refueling and add if necessary.
Oil and fuel consumption may be
higher than normal.
Front Air Dam (and
Splitter)
If equipped, the front air dam and
splitter have minimal ground
clearance. Under normal operation, the
components will occasionally
contact some road surfaces (speed
bumps, driveway ramps, etc.). This
can be heard inside the vehicle as a
scraping noise. This is normal and
does not indicate a problem.
Use care when approaching bumps
or objects on road surfaces and
avoid them when possible.
If equipped, the Front Lift System
may be used to increase front air
dam or splitter clearance. See
Front
Lift System 0191.
Composite Materials
This vehicle may be equipped with
parts containing carbon fiber,
sheet-molding compound, or other
composite materials.
Dealer-installed accessories may
also contain composite materials.
These parts and accessories may
include the splitter or rocker
extensions.
{Warning
Exposed edges of parts
containing carbon fiber and other
composite materials can be
sharp. Contact with these parts
could result in injury. Use caution
to avoid contacting these parts,
including when washing the
vehicle. If the parts are damaged,
replace the parts promptly with
replacements from your dealer.
{Warning
Rocker extensions may break
under pressure, resulting in
property damage or injury. Do not
stand on the rocker extension or
use it as a step.
