in your field of view.
If equipped with HUD, some information
concerning the operation of the vehicle is
projected onto the windshield.
The HUD information appears as an image
focused out toward the front of the vehicle.
Caution
If you try to use the HUD image as a
parking aid, you may misjudge the
distance and damage your vehicle. Do not
use the HUD image as a parking aid.

Engine Power Messages
REDUCED ACCELERATION DRIVE
WITH CARE
This message displays when the vehicle's
propulsion power is reduced. A reduction in
propulsion power can affect the vehicle's
ability to accelerate. If this message is on,
but there is no observed reduction in
performance, proceed to your destination.
Under certain conditions the performance
may be reduced the next time the vehicle is

16287457) - 2023 - CRC - 3/10/22
Instruments and Controls 99
driven. The vehicle may be driven while this
message is on, but maximum acceleration
and speed may be reduced. Anytime this
message stays on, or displays repeatedly,
the vehicle should be taken to your dealer
for service as soon as possible.
Under certain operating conditions,
propulsion will be disabled. Try restarting
after the ignition has been off for
two minutes.
Vehicle Speed Messages
SPEED LIMITED TO XXX KM/H (MPH)
This message shows that the vehicle speed
has been limited to the speed displayed. The
limited speed is a protection for various
propulsion and vehicle systems, such as
lubrication, thermal, brakes, suspension,
Teen Driver if equipped, or tires.
Universal Remote System
SeeRadio Frequency Statement 0327.
The FCC Grant of Equipment Authorization
Certificate number is NZLSAHL5B.
The Canadian Registration ID number is
4112A-SAHL5B.
Universal Remote System
Programming
If equipped, these buttons are in the
sunshade.
This system can replace up to three remote
control transmitters used to activate devices
such as garage door openers, security
systems, and home automation devices.
These instructions refer to a garage door
opener, but can be used for other devices.
Do not use the Universal Remote system
with any garage door opener that does not
have the stop and reverse feature. This
includes any garage door opener model
manufactured before April 1, 1982. Keep the original hand-held transmitter for
use in other vehicles as well as for future
programming. Erase the programming when
vehicle ownership is terminated. See
“Erasing Universal Remote System Buttons”
later in this section.
To program a garage door opener, park
outside directly in line with and facing the
garage door opener receiver. Clear all people
and objects near the garage door.
Make sure the hand-held transmitter has a
new battery for quick and accurate
transmission of the radio-frequency signal.
Programming the Universal Remote
System
Programming involves time-sensitive actions
and may time out, requiring the procedure
to be repeated. Read these instructions
completely before programming the
Universal Remote system. It may help to
have another person assist with the
programming process.
1. Hold the end of the hand-held transmitter about 3 to 8 cm (1 to 3 in)
away from the Universal Remote system
buttons with the indicator light in view.

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16287457) - 2023 - CRC - 3/10/22
100 Instruments and Controls
The hand-held transmitter was supplied
by the manufacturer of the garage door
opener receiver.
2. Press and release one of the three Universal Remote system buttons to be
programmed. Press and hold the
hand-held transmitter button. Do not
release the hand-held transmitter button
until the indicator light changes from a
slow to a rapid flash or continuous light.
Then release the hand-held transmitter
button.
Some garage door openers may require
substitution of Step 2 with the procedure
under “Radio Signals for Some Gate
Operators” later in this section.
3. Press and hold the newly programmed Universal Remote system button for
five seconds while watching the indicator
light and garage door activation.
.If the indicator light stays on
continuously or the garage door
moves when the button is pressed,
then programming is complete. There
is no need to complete Steps 4–6.
.If the indicator light does not come
on or the garage door does not
move, a second button press may be
required. For a second time, press
and hold the newly programmed
button for five seconds. If the
indicator light stays on continuously
or the garage door moves when the
button is pressed, then programming
is complete. There is no need to
complete Steps 4–6.
.If the garage door does not move,
continue with programming
Steps 4–6.
Learn or Smart Button
4. After completing Steps 1–3, locate the Learn or Smart button inside garage on
the garage door opener receiver. The
name and color of the button may vary
by manufacturer. 5. Press and release the Learn or Smart
button. Step 6 must be completed within
30 seconds of pressing this button.
6. Return to the vehicle and firmly press and hold the trained Universal Remote
system button for two seconds and
release. Repeat the “press/hold/release”
sequence up to three times to complete
the training process.
The Universal Remote system should now
activate the garage door. Repeat the process
for programming the remaining two
buttons.
For questions or programming help, see
www.homelink.com/gm or call
1-800-355-3515. For calls placed outside the
U.S., Canada, or Puerto Rico, international
rates will apply and may differ based on
landline or mobile phone.
Radio Signals for Some Gate Operators
Some gate operators and radio-frequency
laws require transmitter signals to time out
or quit after several seconds of transmission.
This may not be long enough for the
Universal Remote system to pick up the
signal during programming.
