clear roads in shaded areas.
The surface of a curve or an
overpass can remain icy when
the surrounding roads are clear.
Avoid sudden steering
maneuvers and braking while
on ice.
. Turn off cruise control.
Blizzard Conditions
Stop the vehicle in a safe place and
signal for help. Stay with the vehicle
unless there is help nearby.
If possible, use Roadside
Assistance. See Roadside
Assistance Program 0320. To get
help and keep everyone in the
vehicle safe:
. Turn on the hazard warning
flashers.
. Tie a red cloth to an outside
mirror.
{Warning
Snow can trap engine exhaust
under the vehicle. This may
cause exhaust gases to get
inside. Engine exhaust contains
carbon monoxide (CO), which
cannot be seen or smelled. It can
cause unconsciousness and even
death.
If the vehicle is stuck in snow:
. Clear snow from the base of
the vehicle, especially any
blocking the exhaust pipe.
. Open a window about 5 cm
(2 in) on the vehicle side
that is away from the wind,
to bring in fresh air.
. Fully open the air outlets on
or under the instrument
panel.
. Adjust the climate control
system to circulate the air
inside the vehicle and set
(Continued)
Warning (Continued)
the fan speed to the highest
setting. See“Climate
Control Systems.”
For more information about CO,
see Engine Exhaust 0181.
To save fuel, run the engine for
short periods to warm the vehicle
and then shut the engine off and
partially close the window. Moving
about to keep warm also helps.
If it takes time for help to arrive,
when running the engine, push the
accelerator pedal slightly so the
engine runs faster than the idle
speed. This keeps the battery
charged to restart the vehicle and to
signal for help with the headlamps.
Do this as little as possible, to
save fuel.

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.Caution
Overloading the vehicle may
cause damage. Repairs would not
be covered by the vehicle
warranty. Do not overload the
vehicle.
{Warning
Things you put inside your
vehicle can strike and injure
people in a sudden stop or
turn, or in a crash.
.Put things in the rear
area of your vehicle. Try
to spread the weight
evenly.
.Never stack heavier
things, like suitcases,
inside the vehicle so that
some of them are above
the tops of the seats.
(Continued)
Warning (Continued)
.Do not leave an
unsecured child restraint
in your vehicle.
.When you carry
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.
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. .
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. With a
manual transmission, shift to the
next lower gear. This rule
applies at all times, not just
during the break-in period.
. If equipped with a dry sump
engine (Stingray with Z51,
Grand Sport, and Z06), the initial
oil and filter change must be
performed at 800 km (500 mi).
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
If equipped, the front air dam has
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.
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.

180 Driving and Operating
If you still are unable to shift out of
P (Park):1. Fully release the shift lever button, and let go of the shift
lever.
2. While holding down the brake pedal, press the shift lever
button again.
3. Move the shift lever to the desired position.
If you still cannot move the shift
lever from P (Park), consult your
dealer or a professional towing
service.
Parking (Manual
Transmission)
Before exiting the vehicle, move the
shift lever into 1 (First) or
R (Reverse), and apply the parking
brake. Once the shift lever has been
placed into 1 (First) or R (Reverse)
with the clutch pedal pressed in,
turn the ignition off and release the
clutch.
Parking over Things
That Burn
{Warning
Things that can burn could touch
hot exhaust parts under the
vehicle and ignite. Do not park
over papers, leaves, dry grass,
or other things that can burn.
Active Fuel Management
This system allows the engine to
operate on either all or half of its
cylinders, depending on the driving
conditions. With a manual
transmission, the system is only
active in Eco Mode. With an
automatic transmission, the system
is available in all modes, but is more
aggressive in Eco Mode. See Driver
Mode Control 0194.
When less power is required, such
as cruising at a constant vehicle
speed, the system will operate in
the half cylinder mode, allowing the
vehicle to achieve better fuel
economy. When greater power demands are required, such as
accelerating from a stop, passing,
or merging onto a freeway, the
system will maintain full-cylinder
operation.
Extended Parking
It is better not to park with the
vehicle running. If the vehicle is left
while running, follow the proper
steps to be sure the vehicle will not
move and there is adequate
ventilation.
See
Shifting Into Park 0178 and
Engine Exhaust 0181.
If the vehicle is left in P (Park) while
running and the Remote Keyless
Entry (RKE) transmitter is outside
the vehicle, the vehicle will turn off
after one hour.
If the vehicle is left in P (Park) while
running and the RKE transmitter is
inside, the vehicle will run for two
hours. At the end of the second
hour, the vehicle will turn off.
The timer will reset if the vehicle is
taken out of P (Park) while it is
running.

The vehicle can be safely shifted
into R (Reverse) while the vehicle is
moving less than 5 km/h (3 mph).
If the vehicle is going faster than
that, R (Reverse) is locked out.
Caution
A transmission hot message may
display if the manual transmission
fluid is too hot. Driving at high
speed under this condition can
damage the vehicle. Drive at a
slower speed, or stop and idle the
engine to cool the manual
transmission fluid. The message
clears when the vehicle has
slowed and the transmission fluid
has cooled sufficiently.
Shift Speeds
Use the following shift speeds,
shown in km/h (mph), for the best
fuel economy.1 to 4 27 (17)
4 to 5 40 (25)
5 to 6 64 (40)
6 to 7 72 (45)
Caution
When shifting gears, do not move
the shift lever around
unnecessarily. This may damage
the transmission. Shift directly
into the next gear.
1–4 Shift Message
When the DIC displays this
message, the vehicle can only be
shifted from 1 (First) to 4 (Fourth).
Downshifting
Do not downshift into the gear at a
speed greater than shown:1 (First) 72 km/h (45 mph)
2 (Second) 107 km/h (67 mph) 3 (Third) 160 km/h (100 mph)
4 (Fourth) 233 km/h (145 mph)
Caution
When downshifting, if more than
one gear is skipped, or the engine
is racing when the clutch pedal is
released, the engine, clutch,
driveshaft or transmission could
be damaged.
If the engine speed drops below
900 rpm, or if the engine is not
running smoothly, downshift to the
next lower gear. It may be
necessary to downshift two or more
gears.

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
11374030) - 2018 - crc - 4/4/17
188 Driving and Operating
The transmission has a spring that
centers the shift lever near 3 (Third)
and 4 (Fourth). This spring helps to
know what gear the shift lever is in
when shifting. Be careful when
shifting from 1 (First) to 2 (Second)
or downshifting from 7 (Seventh) to
6 (Sixth). The spring will try to pull
the shift lever toward 4 (Fourth) and
3 (Third). Move the lever into
2 (Second) or 6 (Sixth) and do not
let the shift lever move in the
direction of the pulling, or it could
shift from 1 (First) to 4 (Fourth) or
from 7 (Seventh) to 4 (Fourth).
If the vehicle is not upshifted as the
engine speed approaches fuel
shutoff rpm, the engine speed will
be limited to protect the engine. See
Tachometer0104.
Active Rev Match
Vehicles equipped with a manual
transmission have Active Rev Match
(ARM). ARM aids in smoother
shifting by matching the engine
speed to the next selected gear. By
monitoring shift lever and clutch
operation, ARM adjusts engine speed to match a calibrated value
based on gear selection. On
upshifts and downshifts, engine
speed will be increased and
decreased to match vehicle road
speed and transmission gear
position. ARM is maintained while
the clutch pedal is pressed, but will
deactivate if the shift lever is left in
the N (Neutral) position.The system is activated and
deactivated by pressing either of the
paddles marked REV MATCH on
the steering wheel. The system
must be activated with each new
ignition cycle. The system is
normally off.
A gear indicator in the instrument
cluster displays the current gear
selected:
.
When ARM is activated, the
gear number is amber.
. When ARM is deactivated, the
gear number is white.
. A white dash indicates that
service is required. ARM will be
disabled, and the malfunction
indicator lamp will be on. See
Malfunction Indicator Lamp
0109. The clutch and manual
transmission will continue to
operate normally.
