Engine Oil Life System
When to Change Engine Oil
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 OIL SOON message in the Driver
Information Center (DIC) will come on. SeeDIC Warnings
and Messages on page 3-40. Change your oil as soon
as possible within the next 600 miles (1 000 km). 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.
How to Reset the Engine Oil Life
System
The Engine Oil Life System 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 OIL SOON
message being turned on, reset the system.
After changing the engine oil, the system must be reset
as follows:
1. Turn the ignition to RUN, with the engine off.
2. Press the information and reset buttons on the DIC
at the same time to enter the personalization menu.
SeeDIC Vehicle Personalization on page 3-43.
3. Press the information button to scroll through the
available personalization menu modes until the
DIC display shows OIL-LIFE RESET.
4. Press and hold the reset button until the DIC
display shows ACKNOWLEDGED. This will tell you
the system has been reset.
5. Turn the key to LOCK.
If the CHANGE OIL SOON message comes back on
when you start your vehicle, the engine oil life system
has not reset. Repeat the reset procedure.

Jump Starting
If your vehicle’s battery has run down, you may want to
use another vehicle and some jumper cables to start
your vehicle. Be sure to use the following steps to do
it safely.
{CAUTION:
Batteries can hurt you. They can be dangerous
because:
They contain acid that can burn you.
They contain gas that can explode
or ignite.
They contain enough electricity to burn you.
If you do not follow these steps exactly, some or
all of these things can hurt you.
Notice:Ignoring these steps could result in costly
damage to your vehicle that would not be covered
by your warranty.
Trying to start your vehicle by pushing or pulling it
will not work, and it could damage your vehicle.
1. Check the other vehicle. It must have a 12-volt
battery with a negative ground system.Notice:If the other vehicle’s system is not a 12-volt
system with a negative ground, both vehicles can
be damaged. Only use vehicles with 12-volt systems
with negative grounds to jump start your vehicle.
2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles are not touching
each other. If they are, it could cause a ground
connection you do not want. You would not be able
to start your vehicle, and the bad grounding
could damage the electrical systems.
To avoid the possibility of the vehicles rolling, set the
parking brake rmly on both vehicles involved in the
jump start procedure. Put an automatic transaxle in
PARK (P) or a manual transaxle in NEUTRAL before
setting the parking brake.
Notice:If you leave your radio or other accessories
on during the jump starting procedure, they could
be damaged. The repairs would not be covered
by your warranty. Always turn off your radio and
other accessories when jump starting your vehicle.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or the accessory power outlet. Turn off
the radio and all lamps that are not needed.
This will avoid sparks and help save both
batteries. And it could save the radio!

At Least Once a Year
Starter Switch Check
{CAUTION:
When you are doing this inspection, the
vehicle could move suddenly. If the vehicle
moves, you or others could be injured.
1. Before you start, be sure you have enough room
around the vehicle.
2. Firmly apply both the parking brake and the regular
brake. SeeParking Brake on page 2-27.
Do not use the accelerator pedal, and be ready to
turn off the engine immediately if it starts.
3. On automatic transaxle vehicles, try to start the
engine in each gear. The vehicle should start only in
PARK (P) or NEUTRAL (N). If the vehicle starts in
any other position, your vehicle needs service.
On manual transaxle vehicles, put the shift lever
in NEUTRAL (N), push the clutch down halfway, and
try to start the engine. The vehicle should start
only when the clutch is pushed down all the way to
the oor. If the vehicle starts when the clutch is
not pushed all the way down, your vehicle needs
service.
Automatic Transaxle Shift Lock Control
System Check
{CAUTION:
When you are doing this inspection, the
vehicle could move suddenly. If the vehicle
moves, you or others could be injured.
1. Before you start, be sure you have enough room
around the vehicle. It should be parked on a level
surface.
2. Firmly apply the parking brake. SeeParking Brake
on page 2-27.
Be ready to apply the regular brake immediately if
the vehicle begins to move.
3. With the engine off, turn the ignition to RUN, but do
not start the engine. Without applying the regular
brake, try to move the shift lever out of PARK (P)
with normal effort. If the shift lever moves out
of PARK (P), your vehicle needs service.
6-10

Ignition Transaxle Lock Check
While parked, and with the parking brake set, try to turn
the ignition to LOCK in each shift lever position.
With an automatic transaxle, the ignition should turn
to LOCK only when the shift lever is in PARK (P).
The key should come out only in LOCK.
With a manual transaxle, the key should come out
only in LOCK.
Turn the steering wheel to the left and to the right.
It should only lock when turned to the right.
Parking Brake and Automatic Transaxle
Park (P) Mechanism Check
{CAUTION:
When you are doing this check, your vehicle
could begin to move. You or others could be
injured and property could be damaged. Make
sure there is room in front of your vehicle in
case it begins to roll. Be ready to apply the
regular brake at once should the vehicle begin
to move.
Park on a fairly steep hill, with the vehicle facing
downhill. Keeping your foot on the regular brake,
set the parking brake.
To check the parking brake’s holding ability: With
the engine running and transaxle in NEUTRAL (N),
slowly remove foot pressure from the regular
brake pedal. Do this until the vehicle is held by the
parking brake only.
To check the PARK (P) mechanism’s holding
ability: With the engine running, shift to PARK (P).
Then release the parking brake followed by the
regular brake.
