2020 CHEVROLET CORVETTE service interval reset

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
12470550) - 2020 - CRC - 4/23/20
222 Vehicle Care
This vehicle has a racetrack-ready
dry sump engine lubrication system.
This high performance system
operates differently than a standard
engine lubrication system and
requires a special procedure when
changing the engine oil and filter.
SeeEngine Oil 0218.
When the system has calculated
that oil life has been diminished, it
indicates that an oil change is
necessary. A CHANGE ENGINE
OIL SOON message comes on.
Change the oil as soon as possible
within the next 1 000 km (600 mi).
It is possible that, if driving under
the best conditions, the oil life
system may not indicate that an oil
change is necessary for up to a
year. The engine oil and filter must
be changed at least once a year
and, at this time, the system must
be reset. Your dealer has trained
service people who will perform this
work and reset the system. It is also
important to check the oil regularly
over the course of an oil drain
interval and keep it at the proper
level. If the system is ever reset
accidentally, the oil must be
changed at 5 000 km (3,000 mi)
since the last oil change.
Remember to reset the oil life
system whenever the oil is changed.
How to Reset the Engine Oil
Life System
Reset the system whenever the
engine oil is changed so that the
system can calculate the next
engine oil change. To reset the
system:
1. Scroll through the DIC Info Pages menu until the
REMAINING OIL LIFE
percentage is displayed. See
Driver Information Center (DIC)
0108.
2. Press and hold SEL on the DIC while the Oil Life display is
active. The oil life will change
to 100%.
If the CHANGE ENGINE OIL SOON
message comes back on when the
vehicle is started, the engine oil life
system has not reset. Repeat the
procedure.
Dual Clutch Transmission
Fluid
How to Check Dual Clutch
Transmission Fluid
It is not necessary to check the
transmission fluid level.
A transmission fluid leak is the only
reason for fluid loss. If a leak
occurs, take the vehicle to the
dealer and have it repaired as soon
as possible.
The vehicle is not equipped with a
transmission fluid level dipstick.
There is a special procedure for
checking and changing the
transmission fluid. Because this
procedure is difficult, this should be
done at the dealer. Contact the
dealer for additional information or
the procedure can be found in the
service manual. To purchase a
service manual, see Publication
Ordering Information 0311.

driven. Based on driving conditions, the mileage at which a fluid change
is indicated can vary considerably.
For the fluid life system to work
properly, the system must be reset
every time the fluid is changed.
When the system has calculated
that fluid life has been diminished, it
indicates that a fluid change is
necessary. A CHANGE
TRANSMISSION FLUID SOON

change the fluid and reset the
system. If the system is ever reset
accidentally, the fluid must be
changed at 72 000 km (45,000 mi)
since the last fluid change.
