GMC Terrain: Vehicle Checks / Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer system
that indicates when to change the
engine oil and filter. This is based
on a combination of factors which
include engine revolutions, engine
temperature, and miles driven.
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.
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 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 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:
- Display REMAINING OIL LIFE
on the DIC menu.
See Driver Information Center
(DIC) (Base and Midlevel) or Driver Information
Center (DIC) (Uplevel).
- Press and hold V for several
seconds while the Oil Life
display is active to reset the Oil
Life system.
- REMAINING OIL LIFE 100%
will be displayed when the oil
life system is successfully
reset.
The oil life system can also be reset
as follows:
- Place the ignition in Service
Mode. See Ignition Positions.
Display REMAINING OIL LIFE
on the DIC menu.
- See Driver Information Center
(DIC) (Base and Midlevel) or Driver Information
Center (DIC) (Uplevel).
- Fully press and release the
accelerator pedal three times
within five seconds.
- If the display changes to 100%,
the system is reset.
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.
To ensure proper engine
performance and long life, careful
attention must be paid to engine oil.
Following these simple, but
important steps will help protect
your investment:
Use engine oil approved to the
proper specification and of the
proper viscosity grade...
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 your
dealer and have it repaired as soon
as possible...
