Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
9956103) - 2017 - crc - 4/28/16
192 Driving and Operating
When the shift lever is in D (Drive),
press either the right (+) plus paddle
or the left (−) minus paddle to place
the transmission in Temporary
Manual Paddle Shift mode. The
gear indicator by the shift lever, in
the cluster, and in the HUD will
display an M, even though the shift
lever is still in D (Drive). To exit the
system, hold the (+) plus paddle for
more than one second. The system
will return to automatic shifting after
six seconds of cruising at a steady
speed, no manual shifts, no
aggressive cornering, or when the
vehicle comes to a stop.
While the Manual Paddle Shift gear
selection system is active, the
transmission will automatically
downshift through the gears as the
vehicle slows. The transmission willselect 1 (First) gear as the vehicle
stops. From a stop, the vehicle will
start from and hold 1 (First) gear
unless the manual paddle shifts are
used to shift into a different gear,
or D (Drive) is selected.
If the left (−) minus paddle is held
down briefly, the transmission will
downshift to the lowest gear
possible for the vehicle speed. If the
paddle continues to be held as the
vehicle slows, downshifts will
continue to occur as vehicle speed
allows. This feature also works
while in Temporary Manual Paddle
Shift mode, but first press and
release the (−) minus paddle to
enter Temporary Manual Paddle
Shift mode, then press and hold the
(−) minus paddle briefly.
The Manual Paddle Shift system will
not allow an upshift or a downshift if
the vehicle speed is too fast or too
slow, nor will it allow a start from
3 (Third) or higher gear.
If upshifting does not occur when
needed, vehicle speed will be
limited to protect the engine.
When a requested shift is denied
due to the speed restrictions shown,
a DIC message will be displayed,
and the current gear remains
displayed in the cluster and HUD.
Manual Paddle Shift operation is
available for use with cruise control.
See
Cruise Control 0209.
The vehicle speeds required for
Manual Paddle Shift upshifts
depend on several vehicle inputs,
which will vary the allowed upshift
speed by a few km/h (mph).
For Vehicles with a 2.41:1 Axle
Ratio (RPO GXB)
. Upshifts to 3 (Third) gear require
approximately 25 km/h (16 mph).
. Upshifts to 4 (Fourth) gear
require approximately 37 km/h
(23 mph).
. Upshifts to 5 (Fifth) gear require
approximately 48 km/h (30 mph).
. Upshifts to 6 (Sixth) gear require
approximately 60 km/h (37 mph).
. Upshifts to 7 (Seventh) gear
require approximately 74 km/h
(46 mph).

198 Driving and Operating
2. Lift up the EPB switchmomentarily.
The red parking brake status light
will flash and then stay on once the
EPB is fully applied. If the red
parking brake status light flashes
continuously, then the EPB is only
partially applied or there is a
problem with the EPB. A DIC
message will display. Release the
EPB and try to apply it again. If the
light does not come on, or keeps
flashing, have the vehicle serviced.
Do not drive the vehicle if the red
parking brake status light is flashing.
See your dealer. See Electric
Parking Brake Light 0110.
If the amber parking brake warning
light is on, lift up on the EPB switch
and hold it up. Continue to hold the
switch until the red parking brake
status light remains on. If the amber
parking brake warning light remains
on, see your dealer.
If the EPB is applied while the
vehicle is moving, the vehicle will
decelerate as long as the switch is held up. If the switch is held up until
the vehicle comes to a stop, the
EPB will remain applied.
The vehicle may automatically apply
the EPB in some situations when
the vehicle is not moving. This is
normal, and is done to periodically
check the correct operation of the
EPB system.
If the EPB fails to apply, the rear
wheels should be blocked to
prevent vehicle movement.
EPB Release
To release the EPB:
1. Place the ignition in the ACC/ ACCESSORY or ON/RUN/
START position.
2. Apply and hold the brake pedal.
3. Push down momentarily on the EPB switch.
The EPB is released when the red
parking brake status light is off.
If the amber parking brake warning
light is on, release the EPB by
pushing down on the EPB switch and holding it down. Continue to
hold the switch until the red parking
brake status light is off. If either light
stays on after release is attempted,
see your dealer.
Caution
Driving with the parking brake on
can overheat the brake system
and cause premature wear or
damage to brake system parts.
Make sure that the parking brake
is fully released and the brake
warning light is off before driving.
Automatic EPB Release
The EPB will automatically release if
the vehicle is running, placed into
gear, and an attempt is made to
drive away. Avoid rapid acceleration
when the EPB is applied, to
preserve parking brake lining life.
The EPB can also be used to
prevent roll back for vehicles with a
manual transmission taking off on a
hill. When no roll back is desired, an
applied EPB will allow both feet to
be used for the clutch and

the engine rpm to stabilize.
A smooth, quick release of the
brake pedal, while maintaining the
fully pressed accelerator pedal, will
manage wheel slip.
After the vehicle is launched, the
system continues in Competitive
Driving Mode or Performance
Traction Management.
Competitive Driving Mode, PTM,
and Launch Control are systems
designed for a closed course race
track and not intended for use on
public roads. The systems are not
intended to compensate for lack of
driver experience or familiarity with
the race track.Limited-Slip Differential
(Stingray without
Z51 Only)
If equipped, the mechanical
limited-slip differential can give more
traction on snow, mud, ice, sand,
or gravel. It works like a standard
axle most of the time, but when
traction is low, this feature allows
the drive wheel with the most
traction to move the vehicle. For
vehicles with limited-slip differential,
driven under severe conditions, the
rear axle fluid should be changed.
See Competitive Driving Mode
0 205 andMaintenance
Schedule 0307.
Limited-Slip Differential
(Z06, Grand Sport, and
Stingray with Z51)
If equipped, the Electronic
Limited-Slip Differential (eLSD) is
automatically activated. eLSD
actively monitors vehicle sensors
and driver inputs to determine the

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

amount of change for the
conditions. With eLSD, the
vehicle has:
.Enhanced high-speed control.
. Improved traction through
corners, allowing more
acceleration.
. More precise steering.
. Increased vehicle agility.
. Integration with StabiliTrak.
For vehicles with eLSD, driven
under severe conditions, the rear
axle fluid should be changed. See
Competitive Driving Mode 0205
and Maintenance Schedule 0307.Cruise Control
With cruise control, a speed of
about 40 km/h (25 mph) or more
can be maintained without keeping
your foot on the accelerator. Cruise
control does not work at speeds
below about 40 km/h (25 mph).
{Warning
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. Do not use
cruise control on winding roads or
in heavy traffic.
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.
If equipped with a manual
transmission, the cruise control will
remain active when the gears are
shifted. The cruise is disengaged if
the clutch is pressed for several
seconds. If the Traction Control System (TCS)
begins to limit wheel spin while you
are using cruise control, the cruise
control automatically disengages.
See
Traction Control/Electronic
Stability Control 0199. When road
conditions allow for using safely
again, cruise control can be turned
back on.
If the brakes are applied, cruise
control disengages.
1: Press to turn cruise control on
or off. A white indicator comes on in
the instrument cluster when cruise
is turned on.

Driving and Operating 211
While pressing the accelerator pedal
or shortly following the release to
override cruise control, briefly
pressing SET/–will result in cruise
set to the current vehicle speed.
Using Cruise Control on Hills
How well the cruise control works
on hills depends upon the vehicle
speed, load, and the steepness of
the hills. When going up steep hills,
you might have to step on the
accelerator pedal to maintain your
speed. When going downhill, you
might have to brake or shift to a
lower gear to keep your speed
down. If the brake pedal is applied,
cruise control will disengage.
Cruise Control in Manual Paddle
Shift Gear Selection
When the vehicle is in M (Manual
Mode) and the manual paddle shift
controls are not being used, cruise
control operates in the same
manner as D (Drive). When the vehicle is in M (Manual
Mode) and the manual paddle shift
controls are being used, cruise
control operates as follows:
.
If cruise control is active and a
gear is selected with the manual
paddle shift controls, the vehicle
speed is maintained in the driver
selected gear and will not
automatically upshift or
downshift the transmission while
the driver ’s gear selection is
active.
. If driving in hilly terrain, cruise
control may not be able to
maintain vehicle speed if an
upshift or downshift is not
selected by the driver. While
driving on hilly terrain and cruise
control is active with a manual
paddle shift gear selection, the
driver must select the proper
gear for the terrain or select D
(Drive) on the shift lever for full
automatic transmission
operation. Ending Cruise Control
