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.
On some vehicles, when the system
has calculated that oil life has been
diminished, a CHANGE ENGINE
OIL SOON message comes on to
indicate that an oil change is
necessary. 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 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. For vehicles without the
CHANGE ENGINE OIL SOON
message, an oil change is needed
when the OIL LIFE REMAINING
percentage is near 0%. Your dealer
has trained service people who will
perform this work and reset the
system. It is also important to checkthe 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. Always reset the
engine oil life to 100% after every oil
change. It will not reset itself. To
reset the engine oil life system:
1. Display OIL LIFE REMAINING on the DIC. See Driver
Information Center (DIC) (Base
Level) 0129 orDriver
Information Center (DIC)
(Uplevel) 0131. If the vehicle
does not have DIC buttons, the
vehicle must be in P (Park) to
access this display. 2. Press and hold
Von the DIC,
or SET/CLR on the turn signal
lever if the vehicle does not
have DIC buttons, for several
seconds. The oil life will
change to 100%.
The oil life system can also be reset
as follows: 1. Display OIL LIFE REMAINING on the DIC. See Driver
Information Center (DIC) (Base
Level) 0129 orDriver
Information Center (DIC)
(Uplevel) 0131.
2. Fully press the accelerator pedal slowly three times within
five seconds.
If the display shows 100%, the
system is reset.
If the vehicle has a CHANGE
ENGINE OIL SOON message and it
comes back on when the vehicle is
started and/or the OIL LIFE
REMAINING is near 0%, the engine
oil life system has not been 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 your
dealer and have it repaired as soon
as possible.
There is a special procedure for
checking and changing the
transmission fluid. Because this
procedure is difficult, this should be
done at your dealer. Contact your
dealer for additional information or
the procedure can be found in the
service manual. To purchase a
service manual, seePublication
Ordering Information 0358.
Caution
Use of the incorrect automatic
transmission fluid may damage
the vehicle, and the damage may
not be covered by the vehicle
warranty. Always use the correct
automatic transmission fluid. See
Recommended Fluids and
Lubricants 0341.
Change the fluid and filter at the
intervals listed in Maintenance
Schedule 0331, and be sure to use
the fluid listed in Recommended
Fluids and Lubricants 0341.
Manual Transmission
Fluid
How to Check 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 your
dealer and have it repaired as soon as possible. See
Recommended
Fluids and Lubricants 0341 for the
proper fluid to use.
Hydraulic Clutch
For vehicles with a manual
transmission, it is not necessary to
regularly check brake/clutch fluid
unless there is a leak suspected.
Adding fluid will not correct a leak.
A fluid loss in this system could
indicate a problem. Have the
system inspected and repaired.
When to Check and What
to Use
The brake/hydraulic clutch fluid
reservoir cap has this symbol on it.
The common brake/clutch fluid
reservoir is filled with DOT 3 brake
fluid as indicated on the reservoir

280 Vehicle Care
All-Terrain Tires
This vehicle may have all-terrain
tires. These tires provide good
performance on most road surfaces,
weather conditions, and for off-road
driving. SeeOff-Road Driving 0159.
The tread pattern on these tires may
wear more quickly than other tires.
Consider rotating the tires more
frequently than at 12 000 km
(7,500 mi) intervals if irregular wear
is noted when the tires are
inspected. See Tire Inspection
0 291.
Tire Sidewall Labeling
Useful information about a tire is
molded into its sidewall. The
examples show a typical
passenger vehicle tire and a
compact spare tire sidewall.
Passenger (P-Metric) Tire Example
(1) Tire Size:The tire size is a
combination of letters and
numbers used to define a
particular tire's width, height,
aspect ratio, construction type,
and service description. See the
“Tire Size” illustration later in this
section.
(2) TPC Spec (Tire
Performance Criteria
Specification)
:Original
equipment tires designed to
GM's specific tire performance
criteria have a TPC specification code molded onto the sidewall.
GM's TPC specifications meet or
exceed all federal safety
guidelines.
(3) DOT (Department of
Transportation)
:The
Department of Transportation
(DOT) code indicates that the
tire is in compliance with the
U.S. Department of
Transportation Motor Vehicle
Safety Standards.
DOT Tire Date of
Manufacture
:The last four
digits of the TIN indicate the
tire manufactured date. The first
two digits represent the week
(01–52) and the last two digits,
the year. For example, the third
week of the year 2010 would
have a four-digit DOT date
of 0310.
(4) Tire Identification Number
(TIN)
:The letters and numbers
following the DOT (Department
of Transportation) code are the
