Checking Engine Oil
It is a good idea to check the
engine oil every time you get fuel.
In order to get an accurate reading,
the oil must be warm and the
vehicle must be on level ground.
The engine oil dipstick handle
is a yellow loop. SeeEngine
Compartment Overview on
page 5-10for the location of the
engine oil dipstick.
1. Turn off the engine and give the
oil several minutes to drain back
into the oil pan. If you do not
do this, the oil dipstick might not
show the actual level.
2. Pull out the dipstick and clean it
with a paper towel or cloth,
then push it back in all the way.
Remove it again, keeping the
tip down, and check the level.
Service and Appearance Care 5-13

When the system has calculated
that oil life has been diminished,
it indicates that an oil change
is necessary. A CHANGE OIL
message comes on. SeeDIC
Warnings and Messages on
page 3-37. Change the oil as soon
as possible within the next
600 miles (1 000 km). It is possible
that, if driving under the best
conditions, the oil life system might
not indicate that an oil change is
necessary for over a year. However,
the engine oil and lter must be
changed at least once a year and
at this time the system must be
reset. Your dealer/retailer has
trained people who will perform this
work using genuine parts and reset
the system. It is also important
to check the oil regularly and keep it
at the proper level.
If the system is ever reset
accidentally, the oil must be
changed at 3,000 miles (5 000 km)
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
The Engine Oil Life System
calculates when to change the
engine oil and lter based on vehicle
use. Whenever the oil is changed,
reset the system so it can calculate
when the next oil change is required.
If a situation occurs where the oil is
changed prior to a CHANGE OIL
message being turned on, reset the
system.
To reset the Engine Oil Life system:
1. With the engine off, turn the
ignition to ON/RUN.
2. Press and release the stem in
the lower center of the
instrument cluster until the OIL
LIFE message is displayed.
3. Once the alternating OIL LIFE
and RESET messages appear,
press and hold the stem until
several beeps sound. This
conrms that the oil life system
has been reset.
4. Turn the key to LOCK/OFF.If the CHANGE OIL message
comes back on when the vehicle is
started, the engine oil life system
has not reset. Repeat the procedure.
SeeDIC Warnings and Messages
on page 3-37.
What to Do with Used Oil
Used engine oil contains certain
elements that can be unhealthy for
your skin and could even cause
cancer. Do not let used oil stay on
your skin for very long. Clean your
skin and nails with soap and water,
or a good hand cleaner. Wash or
properly dispose of clothing or rags
containing used engine oil. See the
manufacturer’s warnings about the
use and disposal of oil products.
Used oil can be a threat to the
environment. If you change your own
oil, be sure to drain all the oil from the
lter before disposal. Never dispose
of oil by putting it in the trash, pouring
it on the ground, into sewers, or into
streams or bodies of water. Recycle
it by taking it to a place that collects
used oil.

Checking the Fluid Level
To prepare the vehicle:
1. Park the vehicle on a level place.
Keep the engine running.
2. With the parking brake applied,
place the shift lever in P (Park).
3. With your foot on the brake
pedal, move the shift lever
through each gear range,
pausing for about three seconds
in each range. Then, position
the shift lever in P (Park).
4. Let the engine run at idle for
three minutes or more.
Then, without shutting off the
engine:
1. Flip the handle up and then pull
out the dipstick and wipe it with
a clean rag or paper towel.The automatic transmission
dipstick handle with this symbol
on it is located in the engine
compartment on the passenger
side of the vehicle.
SeeEngine Compartment
Overview on page 5-10for more
information on location.
2. Push it back in all the way, wait
three seconds, and pull it back
out again.
3. Check both sides of the dipstick,
and read the lower level.
The uid level must be in
the COLD area, below thecross-hatched area, for a
cold check or in the HOT or
cross-hatched area for a
hot check. Be sure to keep the
dipstick pointed down to get
an accurate reading.
4. If the uid level is in the
acceptable range, push
the dipstick back in all the way;
then ip the handle down to
lock the dipstick in place.
How to Add Automatic
Transmission Fluid
Refer to the Maintenance
Schedule to determine what kind
of transmission uid to use.
SeeRecommended Fluids and
Lubricants on page 6-12.
Add uid only after checking the
transmission uid while it is hot.
A cold check is used only as
a reference. If the uid level is low,
add only enough of the proper
uid to bring the level up to the
HOT area for a hot check.
Service and Appearance Care 5-19

It does not take much uid,
generally less than one pint (0.5 L).
Do not overll.
Notice:Use of the incorrect
automatic transmission uid may
damage the vehicle, and the
damages may not be covered
by the vehicle’s warranty. Always
use the automatic transmission
uid listed inRecommended
Fluids and Lubricants on
page 6-12.
After adding uid, recheck the
uid level as described under
“How to Check Automatic
Transmission Fluid,” earlier
in this section.
When the correct uid level is
obtained, push the dipstick
back in all the way; then ip
the handle down to lock
the dipstick in place.
Manual Transmission
Fluid
When to Check
A good time to check the manual
transmission uid is when the
engine oil is changed. However,
the uid in the manual transmission
does not require changing.
How to Check
Because this operation can be a
little difficult, you may choose
to have this done at your GM
dealer/retailer service department.
If doing it yourself, be sure to follow
all the instructions here, or there
could be a false reading.Notice:Too much or too little
uid can damage your
transmission. Too little uid
could cause the transmission to
overheat. Be sure to get an
accurate reading if you check
your transmission uid.
To check the uid:
1. Park the vehicle on a level
surface, then shut the engine off.
Let the vehicle sit until the
transmission case is cool enough
to touch.
2. Remove the ller plug.

How to Add Coolant to the
Radiator
{CAUTION
An electric engine cooling fan
under the hood can start up even
when the engine is not running and
can cause injury. Keep hands,
clothing, and tools away from any
underhood electric fan.
{CAUTION
Steam and scalding liquids
from a hot cooling system can
blow out and burn you badly.
(Continued)
CAUTION (Continued)
They are under pressure, and if
you turn the surge tank pressure
cap — even a little — they can
come out at high speed.
Never turn the cap when the
cooling system, including the
surge tank pressure cap, is hot.
Wait for the cooling system and
surge tank pressure cap to cool
if you ever have to turn the
pressure cap.
If coolant is needed, add the proper
mixture directly to the radiator,
but be sure the cooling system is
cool before this is done.1. Remove the radiator pressure
cap when the cooling system,
including the upper radiator
hose, is no longer hot.
Turn the pressure cap slowly
counterclockwise about
one full turn.
If you hear a hiss, wait for that
to stop. A hiss means there
is still some pressure left.
2. Keep turning the cap to
remove it.

TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identication code. Any time
you replace one or more of the
TPMS sensors or rotate the
vehicle’s tires, the identication
codes need to be matched to the
new tire/wheel position. The sensors
are matched to the tire/wheel
positions in the following order:
driver side front tire, passenger side
front tire, passenger side rear
tire, and driver side rear tire using a
TPMS diagnostic tool. See your
dealer/retailer for service.
The TPMS sensors can also be
matched to each tire/wheel position
by increasing or decreasing the
tire’s air pressure. If increasing the
tire’s air pressure, do not exceed
the maximum ination pressure
indicated on the tire’s sidewall.
To let air-pressure out of a tire you
can use the pointed end of the
valve cap, a pencil-style air pressure
gage, or a key.You have one minute to match
the rst tire/wheel position,
and ve minutes overall, to match
all four tire/wheel positions. If it
takes longer than one minute, to
match the rst tire and wheel,
or more than ve minutes to match
all four tire and wheel positions,
the matching process stops and you
need to start over.
The TPMS sensor matching
procedure is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to
ON/RUN with the engine off.
3. Turn the exterior lamp switch
from AUTO to OFF four times
within three seconds. A double
horn chirp will sound and
the TPMS low tire warning light
starts ashing. The double
horn chirp and ashing TPMS
warning light indicates the
TPMS matching process has
started. The TPMS warning
light should continue ashingthroughout the matching
procedure. The LOW TIRE
message displays on the Driver
Information Center (DIC).
4. Start with the driver side front tire.
5. Remove the valve cap from the
valve cap stem. Activate the
TPMS sensor by increasing or
decreasing the tire’s air pressure
for 10 seconds, then stop and
listen for a single horn chirp.
The single horn chirp should
sound within 15 seconds,
conrming that the sensor
identication code has been
matched to this tire and wheel
position. If you do not hear
the conrming single horn chirp,
turn the ignition switch to
LOCK and start over beginning
with Step 2.
6. Proceed to the passenger side
front tire, and repeat the
procedure in Step 5.
7. Proceed to the passenger side
rear tire, and repeat the
procedure in Step 5.
