Vehicle Identiﬁcation Vehicle Identiﬁcation Number (VIN) This is the legal identiﬁer for your vehicle. It appears on a plate in the front corner of the instrument panel, on the driver side. You can see it if you look through the windshield from outside your vehicle. The VIN also appears on the Vehicle Certiﬁcation and Service Parts labels and the certiﬁcates of title and registration. Engine Identiﬁcation The eighth character in the VIN is the engine code. This code helps you identify your vehicle’s engine, speciﬁcations, and replacement parts. Service Parts Identiﬁcation Label This label is on your spare tire cover. It is very helpful if you ever need to order parts. The label has the following information: (cid:127) Vehicle Identiﬁcation Number (VIN) (cid:127) Model designation (cid:127) Paint information (cid:127) Production options and special equipment Do not remove this label from the vehicle. 485 Electrical System Add-On Electrical Equipment Notice: Do not add anything electrical to your vehicle unless you check with your dealer ﬁrst. Some electrical equipment can damage your vehicle and the damage would not be covered by your warranty. Some add-on electrical equipment can keep other components from working as they should. Add-on equipment can drain your vehicle’s battery, even if your vehicle is not operating. Your vehicle has an airbag system. Before attempting to add anything electrical to your vehicle, see Servicing Your Airbag-Equipped Vehicle on page 78. Headlamp Wiring The headlamp wiring is protected by fuses in the fuse block. An electrical overload will cause the lamps to turn off. If this happens, have your headlamp wiring checked right away. Windshield Wiper Fuses The windshield wiper motor is protected by an internal circuit breaker. If the wiper motor overheats due to heavy snow, the wipers will stop until the motor cools and will then restart. 486 Power Windows and Other Power Options Circuit breakers protect the power windows and power seats. When the current load is too heavy, the circuit breaker opens and closes, protecting the circuit until the problem is ﬁxed or goes away. Fuses and Circuit Breakers The wiring circuits in your vehicle are protected from short circuits by a combination of fuses, circuit breakers and fusible thermal links. This greatly reduces the chance of ﬁres caused by electrical problems. Look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Be sure you replace a bad fuse with a new one of the identical size and rating. If a fuse should blow, see your dealer for service immediately. If you ever have a problem on the road and don’t have a spare fuse, you can borrow one that has the same amperage. Just pick some feature of your vehicle that you can get along without – like the radio or cigarette lighter – and use its fuse, if it is the correct amperage. Replace it as soon as you can. The fuses are located in three fuse blocks. One is located in the engine compartment, on the passenger’s side of the vehicle, and the other two are located under the rear seat on both the driver’s and passenger’s side of the vehicle. 487 Underhood Fuse Block 488 The underhood fuse block is located in the front of the engine compartment on the passenger’s side of the vehicle. See Engine Compartment Overview on page 373 for more information on location and removal procedure for the front compartment underhood sights shields. To access the fuses, push in the tabs located on each side of the fuse block cover, then lift the cover off.

Avoid contact between the rear seat and the fuse center whenever you remove or reinstall the rear seat. Do not remove covers from any of the covered parts, and do not store anything under the seats. To remove the rear seat cushion, do the following: 1. Pull up on the front of the cushion to release the front hooks. 2. Pull the cushion up and out toward the front of the vehicle. 492 3. With the seat cushion lowered, push rearward and then press down on the seat cushion until the spring locks on both ends engage. 4. Check to make sure the safety belts are properly routed and that no portion of any safety belt is trapped under the seat. Also make sure the seat cushion is secured. Rear Underseat Fuse Block {CAUTION: A safety belt that is not properly routed through the seat cushion or is twisted will not provide the protection needed in a crash. If the safety belt has not been routed through the seat cushion at all, it will not be there to work for the next passenger. The person sitting in that position could be badly injured. After reinstalling the seat cushion, always check to be sure that the safety belts are properly routed and are not twisted. 1. Buckle the center passenger position safety belt, then route the safety belts through the proper slots in the seat cushion. Do not let the safety belts get twisted. 2. Slide the rear of the cushion up and under the seatback so the rear-locating guides hook into the wire loops on the back frame. There is a fuse block located under the rear seat on the driver’s side and passenger’s side of the vehicle. The rear seat cushion must be removed to access the fuse blocks. See “Removing the Rear Seat Cushion” listed previously in this section.

Maintenance Requirements Notice: Maintenance intervals, checks, inspections, replacement parts, and recommended ﬂuids and lubricants as prescribed in this manual are necessary to keep your vehicle in good working condition. Any damage caused by failure to follow scheduled maintenance might not be covered by warranty. Have you purchased the GM Protection Plan? The Plan supplements your new vehicle warranties. See your Warranty and Owner Assistance booklet or your dealer for details. 502 Your Vehicle and the Environment Proper vehicle maintenance not only helps to keep your vehicle in good working condition, but also helps the environment. All recommended maintenance is important. Improper vehicle maintenance can even affect the quality of the air we breathe. Improper ﬂuid levels or the wrong tire inﬂation can increase the level of emissions from your vehicle. To help protect our environment, and to keep your vehicle in good condition, be sure to maintain your vehicle properly. Using the Maintenance Schedule We at General Motors want to help you keep your vehicle in good working condition. But we do not know exactly how you will drive it. You may drive very short distances only a few times a week. Or you may drive long distances all the time in very hot, dusty weather. You may use your vehicle in making deliveries. Or you may drive it to work, to do errands, or in many other ways. Because of all the different ways people use their vehicles, maintenance needs vary. You may need more frequent checks and replacements. So please read the following and note how you drive. If you have any questions on how to keep your vehicle in good condition, see your GM Goodwrench® dealer. 503 This schedule is for vehicles that: (cid:127) carry passengers and cargo within recommended limits. You will ﬁnd these limits on the Tire and Loading Information label. See Loading Your Vehicle on page 349. (cid:127) are driven on reasonable road surfaces within legal driving limits. (cid:127) use the recommended fuel. See Gasoline Octane on page 365. The services in Scheduled Maintenance on page 505 should be performed when indicated. See Additional Required Services on page 508 and Maintenance Footnotes on page 510 for further information. {CAUTION: Performing maintenance work on a vehicle can be dangerous. In trying to do some jobs, you can be seriously injured. Do your own maintenance work only if you have the required know-how and the proper tools and equipment for the job. If you have any doubt, see your GM Goodwrench® dealer to have a qualiﬁed technician do the work. Some maintenance services can be complex. So, unless you are technically qualiﬁed and have the necessary equipment, you should have your GM Goodwrench® dealer do these jobs. When you go to your GM Goodwrench® dealer for your service needs, you will know that GM-trained and supported service technicians will perform the work using genuine GM parts. 504 If you want to purchase service information, see Service Publications Ordering Information on page 543. Owner Checks and Services on page 512 tells you what should be checked, when to check it, and what you can easily do to help keep your vehicle in good condition. The proper replacement parts, ﬂuids, and lubricants to use are listed in Recommended Fluids and Lubricants on page 516 and Normal Maintenance Replacement Parts on page 518. When your vehicle is serviced, make sure these are used. All parts should be replaced and all necessary repairs done before you or anyone else drives the vehicle. We recommend the use of genuine GM parts. Scheduled Maintenance When the CHANGE ENGINE OIL SOON message in the Driver Information Center (DIC) comes on, it means that service is required for your vehicle. Have your vehicle serviced 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 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. Your GM Goodwrench® dealer has GM-trained service technicians who will perform this work using genuine GM parts and reset the system. 505 If the engine oil life system is ever reset accidentally, you must service your vehicle within 3,000 miles (5 000 km) since your last service. Remember to reset the oil life system whenever the oil is changed. See Engine Oil Life System on page 383 for information on the Engine Oil Life System and resetting the system. When the CHANGE ENGINE OIL SOON message appears, certain services, checks, and inspections are required. Required services are described in the following for “Maintenance I” and “Maintenance II.” Generally, it is recommended that your ﬁrst service be Maintenance I, your second service be Maintenance II, and that you alternate Maintenance I and Maintenance II thereafter. However, in some cases, Maintenance II may be required more often. Maintenance I — Use Maintenance I if the CHANGE ENGINE OIL SOON message comes on within 10 months since the vehicle was purchased or Maintenance II was performed. Maintenance II — Use Maintenance II if the previous service performed was Maintenance I. Always use Maintenance II whenever the message comes on 10 months or more since the last service or if the message has not come on at all for one year. 506 Scheduled Maintenance Service Maintenance I Maintenance II Change engine oil and ﬁlter.

We, however, urge that all recommended maintenance services be performed at the indicated intervals and the maintenance be recorded. (a) Visually inspect brake lines and hoses for proper hook-up, binding, leaks, cracks, chaﬁng, etc. Inspect disc brake pads for wear and rotors for surface condition. Inspect other brake parts, including calipers, parking brake, etc. (b) Visually inspect front and rear suspension and steering system for damaged, loose, or missing parts or signs of wear. Inspect power steering lines and hoses for proper hook-up, binding, leaks, cracks, chaﬁng, etc. (c) Visually inspect hoses and have them replaced if they are cracked, swollen, or deteriorated. Inspect all pipes, ﬁttings, and clamps; replace with genuine GM parts as needed. To help ensure proper operation, a pressure test of the cooling system and pressure cap and cleaning the outside of the radiator and air conditioning condenser is recommended at least once a year. (d) Visually inspect wiper blades for wear or cracking. Replace wiper blades that appear worn or damaged or that streak or miss areas of the windshield. (e) Make sure the safety belt reminder light and all your belts, buckles, latch plates, retractors, and anchorages are working properly. Look for any other loose or damaged safety belt system parts. If you see anything that might keep a safety belt system from doing its job, have it repaired. Have any torn or frayed safety belts replaced. Also look for any opened or broken airbag coverings, and have them repaired or replaced. The airbag system does not need regular maintenance. 510 (f) Lubricate all key lock cylinders. Lubricate all hinges and latches, including those for the hood, rear compartment, glove box door, and console door. More frequent lubrication may be required when exposed to a corrosive environment. Applying silicone grease on weatherstrips with a clean cloth will make them last longer, seal better, and not stick or squeak. (g) If you drive regularly under dusty conditions, the ﬁlter may require replacement more often. (h) Change automatic transmission ﬂuid and ﬁlter if the vehicle is mainly driven under one or more of these conditions: − In heavy city traffic where the outside temperature regularly reaches 90°F (32°C) or higher. − In hilly or mountainous terrain. − When doing frequent trailer towing. − Uses such as limousine service. − Uses such as high performance operation. (i) If using DOT-4 brake ﬂuid only: Drain, ﬂush, and reﬁll brake hydraulic system at a regular maintenance service (I or II) every two years. This service can be complex; you should have your dealer perform this service. See Brakes on page 405. (j) Drain, ﬂush, and reﬁll cooling system. This service can be complex; you should have your dealer perform this service. See Engine Coolant on page 389 for what to use. Inspect hoses. Clean radiator, condenser, pressure cap, and ﬁller neck. Pressure test the cooling system and pressure cap. (k) A ﬂuid loss in any vehicle system could indicate a problem. Have the system inspected and repaired and the ﬂuid level checked. Add ﬂuid if needed. (l) Inspect throttle body bore and valve plates for deposits. Open the throttle valve and inspect all surfaces. Clean as required. (m) If you drive regularly under dusty conditions, inspect the ﬁlter at each engine oil change. 511 (n) Visually inspect belt for fraying, excessive cracks, or obvious damage. Replace belt if necessary. (o) Drain, ﬂush, and reﬁll intercooler system. This service can be complex; you should have your dealer perform this service. See Engine Coolant on page 389 (p) For supercharged engines only: Have your dealer check the supercharger oil level and add the proper supercharger oil as needed (or every 36 months, whichever occurs ﬁrst). See Recommended Fluids and Lubricants on page 516 Owner Checks and Services These owner checks and services should be performed at the intervals speciﬁed to help ensure the safety, dependability, and emission control performance of your vehicle. Your GM Goodwrench® dealer can assist you with these checks and services. Be sure any necessary repairs are completed at once. Whenever any ﬂuids or lubricants are added to your vehicle, make sure they are the proper ones, as shown in Recommended Fluids and Lubricants on page 516. 512 It is important to check the engine oil At Each Fuel Fill It is important to perform these underhood checks at each fuel ﬁll. Engine Oil Level Check Check the engine oil level and add the proper oil if necessary. See Engine Oil on page 380 for further details. Notice: regularly and keep it at the proper level. Failure to keep the engine oil at the proper level can cause damage to the engine not covered by your warranty. Engine Coolant Level Check Check the engine coolant level and add DEX-COOL® coolant mixture if necessary. See Engine Coolant on page 389 for further details. Intercooler Coolant Level Check (4.4L Supercharged Engine) Check the coolant level and add DEX-COOL® coolant mixture if necessary. See Engine Coolant on page 389 for further details. Windshield Washer Fluid Level Check Check the windshield washer ﬂuid level in the windshield washer ﬂuid reservoir and add the proper ﬂuid if necessary. At Least Once a Month Tire Inﬂation Check Visually inspect your vehicle’s tires and make sure they are inﬂated to the correct pressures. Do not forget to check the spare tire. See Inﬂation - Tire Pressure on page 431. Check to make sure the spare tire is stored securely. See Changing a Flat Tire on page 464. Tire Wear Inspection Tire rotation is recommended if your vehicle has the same size tires at all four wheel positions and may be required for high mileage highway drivers prior to the Engine Oil Life System service notiﬁcation. Check the tires for wear and, if necessary, rotate the tires. See Tire Inspection and Rotation on page 438. 513 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. See Parking Brake on page 121. Do not use the accelerator pedal, and be ready to turn off the engine immediately if it starts. 3. 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, contact your GM Goodwrench® dealer for service. 514 Automatic Transmission 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. See Parking Brake on page 121. Be ready to apply the regular brake immediately if the vehicle begins to move. 3. With the engine off and 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), contact your GM Goodwrench® dealer for service. Parking Brake and Automatic Transmission 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. (cid:127) To check the parking brake’s holding ability: With the engine running and transmission in NEUTRAL (N), slowly remove foot pressure from the regular brake pedal. Do this until the vehicle is held by the parking brake only. (cid:127) 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. Contact your GM Goodwrench® dealer if service is required. Underbody Flushing Service At least every spring, use plain water to ﬂush any corrosive materials from the underbody. Take care to clean thoroughly any areas where mud and other debris can collect. 515 Recommended Fluids and Lubricants Fluids and lubricants identiﬁed below by name, part number, or speciﬁcation can be obtained from your dealer. Usage Fluid/Lubricant The engine requires a special engine oil meeting GM Standard GM4718M. Oils meeting this standard can be identiﬁed as synthetic, and should also be identiﬁed with the American Petroleum Institute (API) Certiﬁed for Gasoline Engines starburst symbol. However, not all synthetic API oils with the starburst symbol will meet this GM standard. You should look for and use only oil that meets GM Standard GM4718M. GM Goodwrench® oil meets all the requirements for your vehicle. For the proper viscosity, see Engine Oil on page 380. 50/50 mixture of clean, drinkable water and use only DEX-COOL® Coolant.

Normally, any concerns with the sales transaction or the operation of your vehicle will be resolved by your dealer’s sales or service departments. Sometimes, however, despite the best intentions of all concerned, misunderstandings can occur. If your concern has not been resolved to your satisfaction, the following steps should be taken: STEP ONE: Discuss your concern with a member of dealership management. Normally, concerns can be quickly resolved at that level. If the matter has already been reviewed with the sales, service or parts manager, contact the owner of the dealership or the general manager. STEP TWO: If after contacting a member of dealership management, it appears your concern cannot be resolved by the dealership without further help, contact the Cadillac Customer Assistance Center, 24 hours a day, by calling 1-800-458-8006. In Canada, contact the Canadian Cadillac Customer Communication Centre by calling 1-888-446-2000. We encourage you to call the toll-free number in order to give your inquiry prompt attention. Please have the following information available to give the Customer Assistance Representative: (cid:127) Vehicle Identiﬁcation Number (VIN). This is available from the vehicle registration or title, or the plate at the top left of the instrument panel and visible through the windshield. (cid:127) Dealership name and location. (cid:127) Vehicle delivery date and present mileage. When contacting Cadillac, please remember that your concern will likely be resolved at a dealer’s facility. That is why we suggest you follow Step One ﬁrst if you have a concern. 526 You may contact the BBB Auto Line Program using the toll-free telephone number or write them at the following address: BBB Auto Line Program Council of Better Business Bureaus, Inc. 4200 Wilson Boulevard Suite 800 Arlington, VA 22203-1838 Telephone: 1-800-955-5100 This program is available in all 50 states and the District of Columbia. Eligibility is limited by vehicle age, mileage and other factors. General Motors reserves the right to change eligibility limitations and/or discontinue its participation in this program. STEP THREE: Both General Motors and your dealer are committed to making sure you are completely satisﬁed with your new vehicle. However, if you continue to remain unsatisﬁed after following the procedure outlined in Steps One and Two, you should ﬁle with the BBB Auto Line Program to enforce any additional rights you may have. Canadian owners refer to your Warranty and Owner Assistance Information booklet for information on the Canadian Motor Vehicle Arbitration Plan (CAMVAP). The BBB Auto Line Program is an out of court program administered by the Council of Better Business Bureaus to settle automotive disputes regarding vehicle repairs or the interpretation of the New Vehicle Limited Warranty. Although you may be required to resort to this informal dispute resolution program prior to ﬁling a court action, use of the program is free of charge and your case will generally be heard within 40 days. If you do not agree with the decision given in your case, you may reject it and proceed with any other venue for relief available to you. 527 Online Owner Center Online Owner Center (United States only) The Owner Center is a resource for your GM ownership needs.

Scheduling Service Appointments When your vehicle requires warranty service, you should contact your dealer and request an appointment. By scheduling a service appointment and advising your service consultant of your transportation needs, your dealer can help minimize your inconvenience. If your vehicle cannot be scheduled into the service department immediately, keep driving it until it can be scheduled for service, unless, of course, the problem is safety-related. If it is, please call your dealership, let them know this, and ask for instructions. If the dealer requests that you simply drop the vehicle off for service, you are urged to do so as early in the work day as possible to allow for the same day repair. Transportation Options Warranty service can generally be completed while you wait.
