Climate Controls Personalization
If your vehicle is equipped with this feature, you
can store and recall climate control settings for the
temperature, the fan speed and the direction of
the air¯ow.
Memory buttons 1 and 2 are located on the driver's door
panel and correspond to the numbers 1 or 2 found on
the back of each remote keyless entry transmitter.
To recall the climate control settings last stored on your
transmitter, press the unlock button on your remote
keyless entry transmitter and put the ignition in
ACCESSORY or ON. The settings will be recalled.
To change the stored settings, do the following:
1. Select the desired temperature, fan speed and
air¯ow mode. If desired, a separate temperature
setting may also be selected for the front seat
passenger. For information on how to do this, see
Dual Climate Control System on page 3-29.2. Locate memory buttons 1 and 2 on the driver's
door panel.
3. Press the memory button on the door panel that
corresponds to the number on the back of the
transmitter you are programming, until you hear two
beeps. The beeps con®rm that your selection has
been saved and can now be recalled. For more
information on the memory feature, see
Memory
Seat, Mirrors and Steering Wheel on page 2-55.
Follow these steps each time you want to change the
stored settings.

LIFE is displayed. (This only needs to be reset after
you have had the oil changed.)
·TRANSMISSION FLUID LIFE:Under normal
conditions, the rate of deterioration of the
transmission ¯uid is slow. See
Part A: Scheduled
Maintenance Services on page 6-4for proper
¯uid and change intervals. To reset the transmission
¯uid life, press the INFO button to display TRANS
FLUID LIFE, then press and hold the INFO
RESET button until 100% TRANS FLUID LIFE is

CHANGE ENGINE OIL ± 82:This means that the life
of the engine oil has expired and it should be changed
within 200 miles. After an oil change, the Oil Life
Indicator must be reset. See
Oil Life Indicator on
page 3-79. SeeEngine Oil on page 5-13.
CHANGE TRANS FLUID ± 47:This message will
appear when it is time to change the transaxle ¯uid. See
Part A: Scheduled Maintenance Services on page 6-4for the proper ¯uid and change intervals.
CHECK BRAKE FLUID ± 37:This message will
display if the ignition is in ON to inform the driver that
the brake ¯uid level is low. Have the brake system
serviced by a technician as soon as possible. See
Brake
System Warning and Parking Brake Indicator Light on
page 3-47
.
CHECK COOLANT LEVEL ± 2:This message will
appear when there is a low level of engine coolant. Have
the cooling system serviced by a technician as soon
as possible. See
Engine Coolant on page 5-24.
CHECK FUEL GAGE ± 50:(Analog Cluster) This
message will appear when the fuel supply is less than
5 gallons (18.9 L) and the display is turned off. A
single chime will also sound when this message is
displayed.
CHECK GAS CAP ± 61:This message will appear if
the gas cap has not been fully tightened. You should
recheck your gas cap to ensure that it's on properly.CHECK OIL LEVEL ± 36:For correct operation of the
low oil sensing system, your vehicle should be on a
level surface. A false CHECK OIL LEVEL message may
appear if the vehicle is parked on a grade. The oil
level sensing system does not check for actual oil level
if the engine has been off for a short period of time,
and the oil level is never checked while the engine is
running. If the CHECK OIL LEVEL message appears,
and your vehicle has been parked on level ground
with the engine off for at least 30 minutes, the oil level
should be checked by observing the oil dipstick. Prior to
checking the oil level, be sure the engine has been
off for a few minutes and your vehicle is on a level
surface. Then check the dipstick and add oil if
necessary. See
Engine Oil on page 5-13.
CHECK TIRE PRESSURE ± 144:This message is
displayed when the Tire Pressure Monitor (TPM) system
detects a low or high tire pressure condition in one or
more of the road tires. By pressing the INFO button up or
down, the DIC display will show which tire or tires do not
have the correct in¯ation pressure. A ªLOW TIREº
condition exists when the tire's air pressure is under
25 psi (172 kPa) and a ªHIGH TIREº condition exists
when the tire's air pressure is above 38 psi (262 kPa).
The system will display the air pressure, the tire location
(LF, RF, RR or LR) and if the air pressure is low or high.
The tire pressure information is available in English or
metric measurements. For example, a driver's side front
tire that is low may be shown as: 22 PSI LF TIRE LOW.

Trip Computer
Oil Life Indicator
This feature lets you know when to change the engine
oil. It's based on the engine oil temperatures and
your driving patterns.To see the display, press the INFO button several times
until ENGINE OIL LIFE appears. If you see 99%
ENGINE OIL LIFE, 99 percent of your current oil life
remains.
The DIC may display a CHANGE ENGINE OIL
message. For more information, see
Scheduled
Maintenance on page 6-4. If you see CHANGE ENGINE
OIL, it means the oil life is gone and you should
change the oil right away. The system doesn't check
how much oil you have, so you'll still have to check for
that. To see how, see
Engine Oil on page 5-13.
When the oil is changed, you'll need to reset the system.
See
Engine Oil on page 5-13. Always keep a written
record of the mileage and date when you changed
your oil.

The anti-lock system can change the brake pressure
faster than any driver could. The computer is
programmed to make the most of available tire and road
conditions. This can help you steer around the obstacle
while braking hard.
As you brake, your computer keeps receiving updates
on wheel speed and controls braking pressure
accordingly.Remember: Anti-lock doesn't change the time you need
to get your foot up to the brake pedal or always
decrease stopping distance. If you get too close to the
vehicle in front of you, you won't have time to apply
your brakes if that vehicle suddenly slows or stops.
Always leave enough room up ahead to stop, even
though you have anti-lock brakes.
Using Anti-Lock
Don't pump the brakes. Just hold the brake pedal down
®rmly and let anti-lock work for you. You may hear
the anti-lock pump or motor operate, and feel the brake
pedal pulsate, but this is normal.
Braking in Emergencies
With anti-lock, you can steer and brake at the same
time. In many emergencies, steering can help you more
than even the very best braking.

·Do not get too close to the vehicle you want to
pass while you're awaiting an opportunity. For
one thing, following too closely reduces your area
of vision, especially if you're following a larger
vehicle. Also, you won't have adequate space if the
vehicle ahead suddenly slows or stops. Keep
back a reasonable distance.
·When it looks like a chance to pass is coming up,
start to accelerate but stay in the right lane and
don't get too close. Time your move so you will be
increasing speed as the time comes to move
into the other lane. If the way is clear to pass, you
will have a ªrunning startº that more than makes
up for the distance you would lose by dropping
back. And if something happens to cause you to
cancel your pass, you need only slow down
and drop back again and wait fo another
opportunity.
·If other vehicles are lined up to pass a slow vehicle,
wait your turn. But take care that someone isn't
trying to pass you as you pull out to pass the slow
vehicle. Remember to glance over your shoulder
and check the blind spot.
·Check your mirrors, glance over your shoulder, and
start your left lane change signal before moving out
of the right lane to pass. When you are far enough
ahead of the passed vehicle to see its front in your
inside mirror, activate your right lane change signal
and move back into the right lane. (Remember that
your right outside mirror is convex. The vehicle you
just passed may seem to be farther away from you
than it really is.)
·Try not to pass more than one vehicle at a time on
two-lane roads. Reconsider before passing the
next vehicle.
·Don't overtake a slowly moving vehicle too rapidly.
Even though the brake lamps are not ¯ashing, it may
be slowing down or starting to turn.
·If you're being passed, make it easy for the following
driver to get ahead of you. Perhaps you can ease a
little to the right.
Loss of Control
Let's review what driving experts say about what happens
when the three control systems (brakes, steering and
acceleration) don't have enough friction where the tires
meet the road to do what the driver has asked.
In any emergency, don't give up. Keep trying to steer
and constantly seek an escape route or area of
less danger.

As in the chart shown previously, SAE 5W-30 is the
only viscosity grade recommended for your vehicle. You
should look for and use only oils which have the API
Starburst symbol and which are also identi®ed as
SAE 5W-30. If you cannot ®nd such SAE 5W-30 oils,
you can use an SAE 10W-30 oil which has the API
Starburst symbol, if it's going to be 0ÉF (-18ÉC)
or above. Do not use other viscosity grade oils, such as
SAE 10W-40 or SAE 20W-50 under any conditions.
Notice:Use only engine oil with the American
Petroleum Institute Certi®ed For Gasoline Engines
starburst symbol. Failure to use the recommended
oil can result in engine damage not covered by
your warranty.
GM Goodwrench
žoil meets all the requirements for
your vehicle.
If you are in an area of extreme cold, where the
temperature falls below-20ÉF (-29ÉC), it is
recommended that you use either an SAE 5W-30
synthetic oil or an SAE 0W-30 oil. Both will provide
easier cold starting and better protection for your engine
at extremely low temperatures.
Engine Oil Additives
Don't add anything to your oil. The recommended oils
with the starburst symbol are all you will need for
good performance and engine protection.
When to Change Engine Oil
(GM Oil Life System)
Your vehicle has a computer system that lets you know
when to change the engine oil and ®lter. This is based on
engine revolutions and engine temperature, and not on
mileage. Based on driving conditions, the mileage at
which an oil change will be indicated can vary
considerably. For the oil life system to work properly, you
must reset the system every time the oil is changed.
When the system has calculated that oil life has been
diminished, it will indicate that an oil change is necessary.
A CHANGE ENGINE OIL message in the Driver
Information Center (DIC) will come on. Change your oil
as soon as possible within the next two times you stop for
fuel. It is possible that, if you are driving under the best
conditions, the oil life system may not indicate that an oil
change is necessary for over a year. However, your
engine oil and ®lter must be changed at least once a year
and at this time the system must be reset. Your dealer
has GM-trained service people who will perform this work
using genuine GM parts and reset the system. It is also
important to check your oil regularly and keep it at the
proper level.
If the system is ever reset accidentally, you must
change your oil at 3,000 miles (5 000 km) since your
last oil change. Remember to reset the oil life system
whenever the oil is changed.
5-17

How to Reset the CHANGE ENGINE OIL
Message
The GM Oil Life SystemŸ calculates when to change
your engine oil and ®lter based on vehicle use. Anytime
your oil is changed, reset the system so it can calculate
when the next oil change is required. If a situation occurs
where you change your oil prior to a CHANGE ENGINE
OIL message in the Driver Information Center (DIC) being
turned on, reset the system.
After the oil has been changed, the CHANGE ENGINE
OIL message must be reset. To reset the message,
do the following:
1. Turn the key to the ªONº position without starting
the engine.
2. Press the INFO button on the Driver Information
Center (DIC) until ENGINE OIL LIFE is displayed.
3. Press and hold the INFO RESET button until 100%
ENGINE OIL LIFE is displayed. This resets the oil
life indicator.
The percentage of oil life remaining may be checked at
any time by pressing the INFO button until ENGINE
OIL LIFE is displayed on the DIC. For more information
on the oil life indicator, see
Oil Life Indicator on
page 3-79.
What to Do with Used Oil
Used engine oil contains certain elements that may be
unhealthy for your skin and could even cause cancer.
Don't 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. Instead, recycle it by
taking it to a place that collects used oil. If you have a
problem properly disposing of your used oil, ask
your dealer, a service station or a local recycling center
for help.

Automatic Transaxle Fluid
When to Check and Change
A good time to check your automatic transaxle ¯uid
level is when the engine oil is changed.
Change both the ¯uid and ®lter every 50,000 miles
(83 000 km) if the vehicle is mainly driven under one or
more of these conditions:
·In heavy city traffic where the outside temperature
regularly reaches 90É F (32É C) or higher.
·In hilly or mountainous terrain.
·When doing frequent trailer towing.
·Uses such as found in taxi, police or delivery
service.
·Use such as limousine service.
If you do not use your vehicle under any of these
conditions, the ¯uid and ®lter do not require change until
the message CHANGE TRANS FLUID appears on
the Driver Information Center.
See
Part A: Scheduled Maintenance Services on
page 6-4.
How to Check
Because this operation can be a little difficult, you may
choose to have this done at the dealership service
department.
If you do it yourself, be sure to follow all the instructions
here, or you could get a false reading on the dipstick.
Notice:Too much or too little ¯uid can damage
your transaxle. Too much can mean that some of the
¯uid could come out and fall on hot engine or
exhaust system parts, starting a ®re. Too little ¯uid
could cause the transaxle to overheat. Be sure
to get an accurate reading if you check your
transaxle ¯uid.
Wait at least 30 minutes before checking the transaxle
¯uid level if you have been driving:
·When outside temperatures are above 90É F (32É C)
·At high speed for quite a while.
·In heavy traffic ± especially in hot weather.
·While pulling a trailer.
To get the right reading, the ¯uid should be at normal
operating temperature, which is 180É F to 200É F
(82É C to 93É C).
Get the vehicle warmed up by driving about 15 miles
(24 km) when outside temperatures are above
50É F (10É C). If it's colder than 50É F (10É C), you
may have to drive longer.
