Using the Maintenance Schedule

Because of all the different ways that customers use their vehicles, maintenance needs vary. Some vehicles may need more frequent inspections and replacements.

This schedule is for vehicles that adhere to certain driving conditions

  1. Vehicles that carry passengers and cargo within recommended limits - These limits are described on the vehicle's Certification/Tire label. Refer to «Label - Vehicle Certification»(/cadillac/cts/i-2002-2007/remont/hoistjack/#general-information) and «Tire Placard»(/cadillac/cts/i-2002-2007/remont/hoistjack/#general-information) .
  2. Vehicles that are driven on reasonable road surfaces within legal driving limits
  3. Vehicles that use the recommended fuel

Perform the services in Scheduled Maintenance when indicated. Refer to Additional Required Services and Maintenance Footnotes for further information.

Refer to Owner Checks and Services for information on the following conditions

  1. What parts should be inspected
  2. When to perform the inspection
  3. What can be done to help keep the vehicle in good condition

Refer to Fluid and Lubricant Recommendations and to Maintenance Items for the proper replacement parts, fluids, and lubricants to use. All parts should be replaced and all necessary repairs done before the vehicle is driven.

Scheduled Maintenance

When the CHANGE ENGINE OIL light comes on, service is required for the vehicle. On vehicles driven under the best conditions, the engine oil life system may not indicate that vehicle service 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 engine oil life system is ever reset accidentally, the customer must have the vehicle serviced within 5 000 km (3,000 mi) since your last service. Reset the oil life system whenever you change the oil. Refer to GM Oil Life System - Resetting for information on the engine Oil Life System and resetting the system.

When the CHANGE ENGINE OIL light appears, certain services and inspections are required. Required services are described in the following paragraphs for Maintenance I and Maintenance II. It is recommended that the first service on a vehicle be Maintenance I, the second service be Maintenance II and that you alternate between the two thereafter. However, in some cases, Maintenance II may be required more often.

Additional Required Services

Footnotes

  1. In heavy city traffic where the outside temperature regularly reaches 32°C (90°F) or higher
  2. In hilly or mountainous terrain
  3. When doing frequent trailer towing
  4. In uses such as found in taxi, police or delivery service

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

  1. The engine requires oil meeting GM Standard GM6094M. Use only oil that meets this standard.
  2. 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 use 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 5 000 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

  1. 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 «Tire Rotation (Directional)»(/cadillac/cts/i-2002-2007/remont/wheel-tire-system/#tires-and-wheels__tire-rotation-directional) or «Tire Rotation (Non-Directional)»(/cadillac/cts/i-2002-2007/remont/wheel-tire-system/#tires-and-wheels__tire-rotation-non-directional) in Tires and Wheels.
  2. 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 «Scheduled Maintenance»(/cadillac/cts/i-2002-2007/remont/lubrication-system/#maintenance-and-lubrication__scheduled-maintenance) for scheduled rotation intervals. When rotating your tires, always use the correct rotation pattern shown here.
  3. Do not include the compact spare tire in your tire rotation.
  4. After the tires have been rotated, adjust the front and rear inflation pressures Refer to «Tire Placard»(/cadillac/cts/i-2002-2007/remont/hoistjack/#general-information) .
  5. Ensure that all wheel nuts are properly tightened. Refer to «Capacities - Approximate Fluid»(/cadillac/cts/i-2002-2007/remont/lubrication-system/#maintenance-and-lubrication__capacities-approximate-fluid) .

Engine Air Cleaner/Filter

Inspect the air cleaner filter every oil change and replace at the first oil change after 40 000 km (25,000 mi).

Automatic Transaxle Fluid

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

  1. In heavy city traffic where the outside temperature regularly reaches 32°C (90°F) or higher
  2. In hilly or mountainous terrain
  3. When doing frequent trailer towing
  4. Uses such as found in taxi, police or delivery service

Manual Transmission Fluid

It is not necessary to check the transmission fluid level. A transmission fluid leak is the only reason for fluid loss. Refer to Fluid and Lubricant Recommendations .

Hydraulic Clutch

The hydraulic clutch linkage is self-adjusting. This system does not have its own reservoir. The reservoir receives fluid from the brake master cylinder reservoir. Refer to Master Cylinder Reservoir Replacement in Hydraulic Brakes.

Cooling System

The cooling system is filled with DEX-COOL engine coolant. This coolant is designed to remain in the vehicle for 5 years or for 166 000 km (100,000 mi), whichever occurs first, if you add only DEX-COOL extended life coolant.

Power Steering Fluid

It is not necessary to regularly check power steering fluid unless you suspect there is a leak in the system or you hear an unusual noise. A fluid loss in this system could indicate a problem. Have the system inspected and repaired. Refer to Power Steering Fluid Leaks in Power Steering System.

Windshield Washer Fluid

When adding windshield washer fluid, be sure to read the instructions before use. If operating the vehicle in an area where the temperature may fall below freezing, use a fluid that has sufficient protection against freezing.

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

  1. 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.
  2. 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 Brake Pad Inspection 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.
