Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer that
indicates when to change the
engine oil and filter. This is based
on engine revolutions and engine
temperature, and not on mileage.
Based on driving conditions, the
mileage at which an oil change is
indicated can vary considerably.
For the oil life system to work
properly, the system must be reset
every time the oil is changed.
Z06, ZR1, and Grand Sport models
have 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 on page 10‑15. When the system has calculated
that oil life has been diminished,
it indicates that an oil change is
necessary. A CHANGE ENGINE
OIL message comes on. Change
the oil as soon as possible within
the next 1 000 km (600 miles). It is
possible that, if driving under the
best conditions, the oil life system
might indicate that an oil change
is not 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 miles)
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. Press the TRIP button so
the OIL LIFE percentage is
displayed.
2. Press RESET and hold for two seconds. OIL LIFE
REMAINING 100% will appear.
If the CHANGE ENGINE OIL
message comes back on when the
vehicle is started, the engine oil life
system has not reset. Repeat the
procedure.

Automatic Transmission
Fluid
How to Check Automatic
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 service department 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 service
department. Contact the dealer
for additional information or theprocedure can be found in the
service manual. To purchase a
service manual, see
Service
Publications Ordering Information
on page 13‑15.
Notice: Use of the incorrect
automatic transmission fluid may
damage the vehicle, and the
damages may not be covered by
the vehicle's warranty. Always
use the automatic transmission
fluid listed in Recommended
Fluids and Lubricants on
page 11‑6.
Change the fluid and filter at the
intervals listed in Scheduled
Maintenance on page 11‑2, and
be sure to use the fluid listed in
Recommended Fluids and
Lubricants on page 11‑6.
Manual Transmission
Fluid
It is not necessary to check the
manual transmission fluid level.
A transmission fluid leak is the
only reason for fluid loss. If a leak
occurs, take the vehicle to the
dealer service department and
have it repaired as soon as
possible. See Recommended Fluids
and Lubricants on page 11‑6 for
the proper fluid to use.

General Information
Notice: Maintenance
intervals, checks, inspections,
recommended fluids, and
lubricants are necessary to
keep this vehicle in good
working condition. Damage
caused by failure to follow
scheduled maintenance might
not be covered by the vehicle
warranty.
As the vehicle owner, you are
responsible for the scheduled
maintenance in this section.
We recommend having your
dealer perform these services.
Proper vehicle maintenance helps
to keep the vehicle in good working
condition, improves fuel economy,
and reduces vehicle emissions for
better air quality. Because of all the different ways
people use vehicles, maintenance
needs vary. The vehicle might need
more frequent checks and services.
Please read the information under
Scheduled Maintenance. To keep
the vehicle in good condition, see
your dealer.
The maintenance schedule is for
vehicles that:
.Carry passengers and cargo
within recommended limits on
the Tire and Loading Information
