Engine Oil
If the LOW OIL LEVEL message appears on the Driver Information Center (DIC),
test the engine oil level right away. Although the driver should test the engine oil
level regularly, this message is an added reminder.
What Kind of Engine Oil to Use
Two factors should be considered when determining type of oil to use in a vehicle:
| • | The engine requires oil meeting GM Standard GM6094M. Use only oil that
meets this standard. |
| • | SAE 5W-30 is the only viscosity grade recommended
for use in GM vehicles. |
| - | If the temperature is greater than -18°C (0°F) and if SAE
5W-30 is not available, you may use SAE 10W-30. |
| - | Oils meeting these requirements should also have the starburst symbol on the
container. This symbol indicates that the oil has been certified by the American Petroleum
Institute (API). |
| - | If the temperature falls below -20°C (-4°F), 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 temperature. |
Engine Oil Additives
Do NOT engine oil additives. The recommended oils with the starburst symbol
that meet GM Standard GM6094M are all that is needed for good performance and
engine protection.
When to Change Engine Oil-GM Oil Life System
The vehicle has a computer system that tells the owner when to change the engine
oil and filter. This system 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,
the system must be reset every time the oil is changed.
When the system has calculated that oil life has been diminished, the system
will indicate that an oil change is necessary. A CHANGE ENGINE OIL message in the
Driver Information Center (DIC) will come on. The oil should be changed within the
next two gasoline fill-ups after this message appears. It is possible that, if the
car is being driven under the best condition, the oil life system may not indicate
that an oil change is necessary for over a year. However, the engine oil and filter
must be changed at least once a year and at this time the system must be reset
If the system is ever rest accidentally, the oil must be changed within 5000 km
(3,000 mi) since the last oil change. Reset the oil life system whenever the
oil is changed.
Tire and Wheel Inspection and Rotation
| • | Tires should be rotated every 8 000-13 000 km
(5,000-8,000 mi). |
| | Any time you notice unusual wear, rotate the tires as soon as possible and test
the wheel alignment. Also inspect for damaged tires or wheels. Refer to in Tires and
Wheels. |
| • | The purpose of regular rotation is to achieve more uniform wear for all
tires on the vehicle. The first rotation is the most important. Refer to for scheduled
rotation intervals. |
| | When rotating your tires, always use the correct rotation pattern shown here. |
| • | Do not include the compact spare tire in your tire rotation. |
| • | After the tires have been rotated, adjust the front and rear inflation
pressures Refer to . |
| • | Ensure that all wheel nuts are properly tightened. Refer to . |
Brake Fluid
Your brake master cylinder reservoir is filled with DOT-3 brake fluid.
There are only two reasons why the brake fluid level in the reservoir might
go down:
| • | The brake fluid goes down to an acceptable level during normal brake lining
wear. When new linings are put in, the fluid level goes back up. |
| • | The fluid may be leaking out of the brake system. If so, fix the brake
system. |
Adding brake fluid will not correct a leak. If you add fluid when the linings
are worn, then the reservoir will contain too much fluid when new brake linings are
installed. You should add or remove brake fluid, as necessary, only when work is being
done on the brake hydraulic system.
Inspect brake lines and hoses for proper hook-up binding, leaks, cracks or
chafing. Inspect disc brake pads for wear. Refer to in Disc Brakes. Inspect the rotors
for poor surface condition. Inspect other brake system components, including brake
calipers and the parking brake. Test the parking brake adjustment. The brakes may
need to be inspected more often if the customer's driving habits or conditions result
in frequent braking.
Air Cleaner Filter Inspection and Replacement
Inspect the air cleaner filter every 25 000 km (15,000 mi)
if driving in dusty conditions. Replace the air cleaner filter every 50 000 km
(30,000 mi) or more often under dusty conditions.
Automatic Transaxle Service
It is not necessary to check the transaxle fluid level. A transaxle fluid leak
is the only reason for fluid loss. Change both the fluid and filter every 83 000 km
(50,000 mi) if the vehicle is mainly driven under one or more of these conditions:
| • | In heavy city traffic where the outside temperature regularly reaches
32°C (90°F) or higher |
| • | In hilly or mountainous terrain |
| • | When doing frequent trailer towing |
| • | Uses such as found in taxi, police or delivery service |
Cooling System Service
The cooling system is filled with DEX-COOL engine coolant. This coolant is designed
to remain in the vehicle for 5 years or for 24 000 km (15,000 mi),
whichever occurs first.
Coolant Surge Tank Pressure Cap
If the pressure cap is not tightly installed, coolant loss and possible engine
damage may occur. Verify that the cap is properly and tightly secured.
Power Steering Fluid
It is not necessary to regularly inspect the power steering fluid unless you
suspect that a leak is present in the system, or if you hear an unusual noise. A fluid
loss in this system could indicate a problem requiring repair.
