3. Check both sides of the dipstick, and read the lower level. The fluid

level must be in the cross-hatched area.

4. If the fluid level is where it should be, push

the dipstick back in all the

way.

How to Add Fluid: Refer to the Maintenance Schedule to determine what kind of transaxle fluid to use. See “Recommended Fluids and Lubricants” in If the fluid level is low, add only enough of the proper fluid to bring the level into the cross-hatched area on the dipstick. It doesn’t take much fluid, generally less than a pint. Don’t overfill. We recommend you use only fluid labeled DEXRON@-IIE, because fluids with that label are by fluid made especially for your automatic transaxle. Damage caused other than DEXRON@-IIE is not covered by your new vehicle warranty. After adding fluid, recheck the fluid level as described under “How to Check.”

When the correct fluid level is obtained, push the dipstick back in all the way.

How To Reset Transaxle Fluid Change Indicator: 4.6L (Northstar) Your vehicle is equipped with a transaxle fluid change indicator. A “CHANGE TRANS FLUID” message will display on the Information Center when the power train computer determines that the transaxle fluid needs to be changed or at each 100,000 miles (160,000 km) interval, whichever occurs first. When this message appears, change the transaxle fluid and reset the transaxle fluid life indicator as follows:

Turn the key “ON” with the engine stopped. Press and hold the “OFF” and “REAR DEFOG” buttons on the climate control simultaneously until the “TRANS FLUID RESET” message appears in the Information Center (between 5 and 20 seconds).

ENGINE COOLANT The following explains your cooling system and how it is low. If you have a problem with engine overheating, see “Engine Overheating” in the Index. The proper coo’ It for your Cadillac will:

to add coolant when

Give freezing protection down to -34°F (-37’C) . Give boiling protection up to 262 ” F (128 ” C) . Protect against rust and corrosion. Help keep the proper engine temperature. Let the warning lights work as they should.

What to Use: Use a mixture of one-half clean water (preferably distilled) and one-half antifreeze that meets “GM Specification 1825-M,” which won’t damage aluminum parts. You can also use a recycled coolant conforming to GM Specification 1825-M with a complete coolant flush and refill. Use GM Engine Coolant Supplement (sealer) with any complete coolant change. If you use these, you don’t need to add anything else.

282

r

A CAUTION

Adding only plain water to your cooling system can be dangerous. Plain water, or some other liquid like alcohol, can boil before the proper coolant mix will. Your vehicle’s coolant warning system is set for the proper coolant mix. With plain water or the wrong mix, your engine could get too hot but you wouldn’t get the overheat warning. Your engine could catch fire and you or others could be burned. Use a 50/50 mix of clean water and a proper antifreeze.

I 4.6 Liter (Northstar) TO Check Coolant When. your engine is cold, the coolant level should be at “FULL COLD”, or a little higher.

Adding Coolant

283

When your engine is warm and the “ENGINE COOLANT LOW” message does not appear on the Driver Information Center, coolant is at the proper fill level.

4.9 Liter To Check Coolant: When your engine is cold, the coolant level should be at “FULL COLD,” or a little higher. When your engine is warm, the level should be up to “FULL HOT,” or a little higher.

To Add Coolant 4.9L If you need more coolant, add the proper mix at the coolant recoverv tank.

A CAUTION

flrrning the radiator pressure cap when the engine and radiator are hot can allow steam and scalding liquids to blow out and bum you badly. With the coolant recovery tank, you will almost never have to add coolant at the radiator. Never turn the

radiator pressure cap -- even a little -- when the engine and

radiator are hot.

Add coolant mix at the recovery tank, but be careful not to spill it.

284

A CAUTION:

You can be burned if you spill coolant on hot engine parts. Coolant contains ethylene glycol, and it will burn if the engine parts are hot enough. Don’t spill coolant on a hot engine.

To Add Coolant 4.6L (Northstar): If you need more coolant, add the proper mix at the coolant surPe tank.

A CAUTION:

lbrning the surge tank pressure cap when the engine and radiator are hot can allow steam and scalding liquids to blow -- even a little -- when the engine and radiator are hot. out and burn you badly. Never turn the surge tank pressure cap You can be burned if you spill coolant on hot engine parts. Coolant contains ethylene glycol, and it will burn if the engine parts are hot enough. Don’t spill coolant on a hot engine.

To Check or Add Coolant: When the engine is cold, the coolant level should be at “FULL COLD,” or a little higher. Remove the pressure cap from the surge tank; use a flashlight as necessary to see into the tank. The coolant Ievel should be at or above the seam inside the tank. If you need more coolant, add the proper mix.

M U T O R OR SURGE TANK PRESSURE CAP

When you replace your radiator or surge tank pressure cap, an AC@ cap is recommended. THERMOSTAT Engine coolant temperature is controlled by a thermostat in the engine coolant system. The thermostat stops the flow of coolant through the radiator until the coolant reaches a preset temperature. When you replace your thermostat, an AC@ thermostat is recommended. POWER STEERING FLUID

How To Check Power Steering Fluid: Unscrew the cap and wipe the dipstick with a clean rag. Replace the cap and completely tighten it. Then remove the cap again and look at the fluid level on the dipstick.

When the engine compartment is hot, the level should be at the “HOT” mark. When the engine compartment is cool, the level should be at the “FULL COLD” mark.

287

What to Add: Refer to the Maintenance Schedule to determine what kind of fluid to use. See “Recommended Fluids and Lubricants” in the Index.

289

NOTICE: e When using eoncentrated washer fluid, follow the

manufacturer inStructfons for adding water. Don't mix water with ready to use washer fluid. Water can cause the solution to freeze and damage your washer fluid tank and other parts of the washer system. Also, water doesn't clean as well as washer fluid. Fill your washer fluid tank only 3/4 full when it's very cold. This allows for expansion, which could darnage the tank if it i s completely full. Don't use radiator antifreeze in pout wlndshicld wuadwr. I t can damage your paint.

B W M S T E R CYZINDER Your brake master cylinder is here. It is filled with DOT-3 brake fluid.

290

There are only two reasons why the brake fluid level in your master cylinder might go down. The first is that 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 other reason is that fluid is leaking out of the brake system. If it is, you should have your brake system fixed, since a leak means that sooner or later your brakes won’t work well, or won’t work at all. So, it isn’t a good idea to “top off” your brake fluid. Adding brake fluid won’t correct a leak. If you add fluid when your linings are worn, then you’ll have too much fluid when you get new brake linings. You should add (or remove) brake fluid, as necessary, only when work is done on the brake hydraulic system.

What to Add: When you do need brake fluid, use only DOT-3 brake fluid -- such as Delco Supreme 11s (GM Part No.1052535). Use new brake fluid from a sealed container only.

REPLACING BRAKE SYSTEM PARTS The braking system on a modern vehicle is complex. Its many parts have to be of top quality and work well together if the vehicle is to have really good braking. Vehicles we design and test have top-quality GM brake parts in them, as your Cadillac does when it is new. When you replace parts of your braking system -- for example, when your brake linings wear down and you have to have new ones put in -- be sure you get new genuine GM replacement parts. If you don’t, your brakes may no longer work properly. For example, if someone puts in brake linings that are wrong for your vehicle, the balance between your front and rear brakes can change, for the worse. The braking performance you’ve come to expect can change in many other ways if someone puts in the wrong replacement brake parts. BATTERY Every new Cadillac has a Delco Freedoms battery. You never have to add water to one of these. When it’s time for a new battery, we recommend a Delco Freedoms battery. Get one that has the catalog number shown on the original battery’s label.

293

‘vehicle Storage If you’re not going to drive your vehicle for 25 days or more, take off the black, negative (-) cable from the battery. This will help keep your battery from running down.

I A CAUTION:

Batteries have acid that can burn you and gas that can explode. You can be badly hurt if you aren’t careful. See “Jump Starting” in the Index for tips on working around a battery without getting hurt.

Contact your dealer to learn how to prepare your vehicle for longer storage periods. Battery Power Loss If you lose battery power or the battery is disconnected, your car’s computer must be programmed. It takes just over’20 minutes to do it. If you want to do it yourself, here’s how: 0 Apply the parking brake.

Make sure the front wheels are straight. 0 Turn off the Electronic Climate Control.

Start the engine in “P” (Park) and let it idle for 15 minutes. Then: Put your foot on the brake pedal, shift the transaxle to @ and let it idle for 3 minutes or more. Do not accelerate the engine. Then: With the car in @ (Drive), turn the Electronic Climate Control to “Auto” and let the engine idle for 3 minutes or more. Turn your engine off.

Now your computer is programmed.

The other label is the Certification label, found on the rear edge of the driver's door. It tells you the gross weight capacity of your vehicle, called the GVWR (Gross Vehicle Weight Rating). The GVWR includes the weight of the vehicle, all occupants, fuel and cargo. Never exceed the GVWR for your vehicle, or the Gross Axle Weight Rating (GAWR) for either the front or rear axle. And, if you do have a heavy load, you should spread it out. Don't carry more than 176 lbs. (80 kg) in your trunk .

A CAUTION:

Do not load your vehicle any heavier than the GVWR or the maximum front and rear GAWRs. If you do, parts on your vehicle can break, or it can change the way your vehicle handles. These could cause you to lose control. Also, overloading can shorten the life of your vehicle.

TIRES We don’t make tires. Your new vehicle comes with high quality tires made by a leading tire manufacturer. These tires are warranted by the tire manufacturers and their warranties are delivered with every new Cadillac. If your spare tire is a different brand than your road tires, you will have a tire warranty folder from each of these manufacturers.

A CAUTION

Poorly maintained and improperly used tires are dangerous. Overloading your tires can cause overheating as a result of too much fkiction. You could have an air-out and a serious accident. See “Loading Your Vehicle” in the Index. Underinflated tires pose the same danger as overloaded tires. The resulting accident could cause serious iqjury. Check all tires frequently to maintain the recommended pressure. Tire pressure should be checked when your tires are cold. Overinflated tires are more likely to be cut, punctured, or broken by a sudden impact, such as when you hit a pothole. Keep tires at the recommended pressure. Worn, old tires can cause accidents. If your tread is badly worn, or if your tires have been damaged, replace them. See “Inflation - Tire Pressure” in this section for inflation pressure adjustment for higher speed driving.

In@tion - Tire Pressure

The Tire-Loading Information label which is located on the driver’s door shows the correct inflation pressures for your tires, when they’re cold. “Cold” means your vehicle has been sitting for at least three hours or driven no more than a mile. If you’ll be driving at speeds higher than 100 mph (160 kmh) where it is legal, raise the “cold” inflation pressure of each tire to 35 psi (240 kPa). When you end this very high speed driving, reduce the “cold” inflation pressures to those listed on the Tire-Loading Information label. Never inflate the tires higher than the maximum “cold” inflation pressures stated on the sidewall of the tires.

307

When to Check Check your tires once a month or more. The Seville tire pressures are:

Front - 28 psi (200 kPa) Rear - 26 psi (179 kPa)

Seville recommended tire size is:

XGT4 IIburing Design Blackwall (P225/6OR16)

The STS tire pressures are: Front - 29 psi (200 kPa) Rear - 29 psi (200 kPa)

308

STS recommended tire size is:

GA Performance Blackwall (P225/60ZR 16)

Don’t forget your compact spare tire. It should be at 60 psi (420 kPa). How to Check Use a good quality pocket-type gage to check tire pressure. Simply looking at the tires will not tell you the pressure, especially if you have radial tires -- which may look properly inflated even if they’re underinflated. If your tires have valve caps, be sure to put them back on. They help prevent leaks by keeping out dirt and moisture. Tire Inspection and Rotation To make your tires last longer, have them inspected and mileages recommended in the Maintenance Schedule. See “Scheduled Maintenance Services” in the Index.

rotated at the

FRONT

Use this rotation pattern.

After the tires have been rotated, adjust the front and rear inflation pressure as shown on the Tire-Loading Information label. Make certain that all wheel nuts are properly tightened. See “Wheel Nut Torque’’ in the Index.

309

A CAUTION:

Rust or dirt on a wheel, or on the parts to which it is fastened, can make wheel nuts become loose after a time. The wheel could come off and cause an accident. When you change a wheel, remove any rust or dirt from places where the wheel attaches to the vehicle. In an emergency, you can use a cloth or a paper towel to do this; but be sure to use a scraper or wire brush later, if you need to, to get all the rust or dirt off. (See “Changing a Flat Tire” in the Index.)

When It3 Time for New Tires

One way to tell when it’s time for new tires is to check the treadwear indicators, which will appear when your tires have only 2/32 inch (1.6 mm) or less of tread remaining.

You need a new tire if 0 You can see the indicators at three places around the tire.

You can see cord or fabric showing through the tire’s rubber. The tread or sidewall is cracked, cut or snagged deep enough to show cord or fabric. The tire has a bump, bulge or split. The tire has a puncture, cut, or other damage that can’t be repaired well because of the size or location of the damage.

310

-

Buying New Tires To find out what kind and size of tires you need, look at the Tire-Loading Information label. The tires installed on your vehicle when it was new had a Tire Performance Criteria Specification (TPC Spec) number on each tire’s sidewall. When you get new tires, get ones with that same TPC Spec number. That way, your vehicle will continue to have tires that are designed to give proper endurance, handling, speed rating, traction, ride and other things during normal service on your vehicle. If your tires have an all-season tread design, the TPC number will be followed by a “MS” (for mud and snow). If you ever replace your tires with those not having a TPC Spec number, make sure they are the same size, load range, speed rating and construction type (bias, bias-belted or radial) as your original tires.

A CAUTION:

Mixing tires could cause you to lose control while driving. If you mix tires of different sizes or types (radial and bias-belted tires), the vehicle may not handle properly, and you could have a crash. Be sure to use the same size and type tires on all four wheels. It’s all right to drive with your compact spare, though. It was developed for use on your vehicle.

Uniform Tire Quality Grading The following information relates to the system developed by the United States National Highway Traffic Safety Administration which grades tires by treadwear, traction and temperature performance. (This applies only to vehicles sold in the United States.)

311

Deadwear The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tire graded 150 would wear one and a half (1 1/2) times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices and differences in road characteristics and climate.

Traction - A, B, C

The traction grades, from highest to lowest are: A, B, and C. They represent the tire’s ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance. Warning: The traction grade assigned to this tire is based on braking (straight-ahead) traction tests and does not include cornering (turning) traction.

Temperature - A, B, C

The temperature grades are A (the highest), B, and C, representing the tire’s resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law. Warning: The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure. Those grades are molded on the sidewalls of passenger car tires.

312

.H

While the tires available as standard or optional equipment on General Motors vehicles may vary with respect to these grades, all such tires meet General Motors performance standards and have been approved for use on General Motors vehicles. All passenger type (P Metric) tires must conform to Federal safety requirements in addition to these grades. Wheel Alignment and Tire Balance The wheels on your vehicle were aligned and balanced carefully at the factory to give you the longest tire life and best overall performance. In most cases, you will not need to have your wheels aligned again. However, if you notice unusual tire wear or your vehicle pulling one way or the other, the alignment may need to be reset. If you notice your vehicle vibrating when driving on a smooth road, your wheels to be rebalanced. meel Replacement Replace any wheel that is bent, cracked or badly rusted. If wheel nuts and wheel nuts should be keep coming loose, the wheel, wheel bolts, replaced. If the wheel leaks air out, replace it (except some aluminum wheels, which can sometimes be repaired). See your Cadillac of these conditions exist. Your dealer will know the kind of wheel you need. Each new wheel should have the same load carrying capacity, diameter, width, offset, and be mounted the same way as the one it replaces. If you need to replace any of your wheels, wheel bolts, or wheel nuts, replace them only with new GM original equipment parts. This way, you will be sure to have the right wheel, wheel bolts, and wheel nuts for your Cadillac model.

A CAUTION

Using the wrong replacement wheels, wheel bolts, or wheel nuts on your vehicle can be dangerous. It could affect the braking and handling of your vehicle, make your tires lose air and make you lose control. You could have a collision in which you or others could be injured. Always use the correct wheel, wheel bolts, and wheel nuts for replacement.

CLEANING THE INSIDE OF YOUR CADILLAC Use a vacuum cleaner often to gct rid o f dwt i1rlll I ~ H I W dirt. \! ~pc t int I with a clean, damp cloth. Your Cadillac dealer has two GM cleaners -- a solvent-type spot lifter and a foam-type powdered cleaner. They will clean normal spots and stains very well. Here are some cleaning tips:

Always read the instructions on the cleaner label. Clean up stains as soon as you can -- before they set. Use a clean cloth or sponge, and change to a clean area often. A soft brush may be used if stains are stubborn.

0 Use solvent-type cleaners in a well-ventilated area only. If you use

them, don't saturate the stained area.

0 If a ring forms after spot cleaning, clean the entire area immediately

or it will set.

SPECIAL CLEANING PROBLEMS Greasy or Oily Stains: Like grease, oil, butter, margarine, shoe polish, coffee with cream, chewing gum, cosmetic creams, vegetable oils, wax crayon, tar and asphalt.

Carefully scrape off excess stain. Then follow the solvent-type instructions above.

0 Shoe polish, wax crayon, tar and asphalt will stain if left on a vehicle seat fabric. They should be removed as soon as possible. Be careful, because the cleaner will dissolve them and may cause them to bleed. Non-Greasy Stains: Like catsup, coffee (black), egg, fruit, fruit juice, milk, soft drinks, wine, vomit, urine and blood. 0 Carefully scrape off excess stain, then sponge the soiled area with cool

water. If a stain remains, follow the foam-type instructions above. If an odor lingers after cleaning vomit or urine, treat the area with a waterbaking soda solution: 1 teaspoon (5 ml) of baking soda to 1 cup (250 ml) of lukewarm water. Finally, if needed, clean lightly with solvent-type cleaner.

Combination Stains: Like candy, ice cream, mayonnaise, chili sauce and unknown stains.

Carefully scrape off excess stain, then clean with cool water and allow to dry. If a stain remains, clean it with solvent-type cleaner.

318

CLENVING WNIZ OR LEATHER Just use warm water and a clean cloth.

Rub with a clean, damp cloth to remove dirt. You may have to do it more than once. Things like tar, asphalt and shoe polish will stain if you don’t get them off quickly. Use a clean cloth and solvent-type vinyl/leather cleaner.

CLEANING THE TOP OF THE INSTRUMENT P m E L Use only mild soap and water to clean the top surfaces of the instrument panel. Sprays containing silicones or waxes may cause annoying reflections in the windshield and even make it difficult to see through the windshield under certain conditions. Care of Wood Panels

Use a clean cloth moistened in warm soapy water (use mild dish washing soap). Dry the wood immediately with a clean cloth. Wood surfaces can be polished using ordinary household furniture polishes. Apply the polish to a clean cloth, then rub the cloth on the wood panel.

CARE OF SAFETYBELTS Keep belts clean and dry.

A CAUTION:

Do not bleach or dye safety belts. If you do, it may severely weaken them. In a crash they might not be able to provide adequate protection. Clean safety belts only with mild soap and lukewarm water.

319

GLASS Glass should be cleaned often. GM Glass Cleaner (GM Part No. 1050427) or a liquid household glass cleaner will remove normal tobacco smoke and dust films. Don’t use abrasive cleaners on glass, because they may cause scratches. Avoid placing decals on the inside rear window, since they may have to be scraped off later. If abrasive cleaners are used on the inside of the rear window, an electric defogger element may be damaged. Any temporary license should not be attached across the defogger grid. CLEANING THE OUTSIDE OF THE WINDSHIELD AND WIPER BLADES If the windshield is not clear after using the windshield washer, or if the wiper blade chatters when running, wax or other material may be on the blade or windshield. Clean the outside of the windshield with GM Windshield Cleaner, Bon-Ami Powders (GM Part No. 1050011). The windshield is clean if beads do not form when you rinse it with water. Clean the blade by wiping vigorously with a cloth soaked in full strength windshield washer solvent. Then rinse the blade with water. Wiper blades should be checked on a regular basis and replaced when worn.

CLEMING THE OUTSIDE OF YOUR CXDILUC The paint finish on your vehicle provides beauty, depth of color, gloss retention and durability. Washing Your Vehicle The best way to preserve your vehicle’s finish is to keep it clean by washing it often with lukewarm or cold water. Don’t wash your vehicle in the direct rays of the sun. Don’t use strong soaps or chemical detergents. Use liquid hand, dish or car washing (non-detergent) soaps. Don’t use cleaning agents that contain acid or abrasives. All cleaning agents should be flushed promptly and not allowed to dry on the surface, or they could stain. Dry the finish with a soft, clean chamois or a 100% cotton towel to avoid surface scratches and water spotting. High pressure car washes may cause water to enter your vehicle. Finish Care Occasional waxing or mild polishing of your Cadillac may be necessary to remove residue from the paint finish. You can get GM approved cleaning products from your dealer. (See “Appearance Care and Materials” in the Index.) Your Cadillac has a “basecoat/clearcoat” paint finish. The clearcoat gives more depth and gloss to the colored basecoat.

WEATHERSTMPS These are places where glass or metal meets rubber. Silicone grease will make them last longer, seal better, and not squeak. Apply silicone grease with a clean cloth at least every six months. SHEET METAL DAlMAGE If your vehicle is damaged and requires sheet metal repair or replacement, make sure the body repair shop applies anti-corrosion material to the parts repaired or replaced to restore corrosion protection. FOREIGNIMATERUL, Calcium chloride and other salts, ice melting agents, road oil and sap, bird droppings, chemicals from industrial chimneys, and other foreign matter can damage your vehicle’s finish surfaces. Use cleaners that are marked safe for painted surfaces for these stains.

322

FINISH D M G E Any stone chips, fractures or deep scratches in the finish should be repaired right away. Bare metal will corrode quickly and may develop into a major repair expense. Minor chips and scratches can be repaired with touch-up materials available from your dealer or other service outlets. Larger areas of finish damage can be corrected in your dealer’s body and paint shop. UNDERBODY2MAINTENANCE Chemicals used for ice and snow removal and dust control can collect on the underbody. If these are not removed, accelerated corrosion (rust) can occur on the underbody parts such as fuel lines, frame, floor pan, and exhaust system even though they have corrosion protection. At least every spring, flush these materials from the underbody with plain water. Clean any areas where mud and other debris can collect. Dirt packed in closed areas of the frame should be loosened before being flushed. Your dealer or an underbody vehicle washing system can do this for you. CHEMICAL PMNT SPOTTING Some weather and atmospheric conditions can create a chemical fallout. Airborne pollutants can fall upon and attack painted surfaces on your vehicle. This damage can take two forms: blotchy, ringlet-shaped discolorations, and small irregular dark spots etched into the paint surface. Although no defect in the paint job causes this, Cadillac will repair, at no charge to the owner, the surfaces of new vehicles damaged by this fallout condition within 12 months or 12,000 miles (20 000 km) of purchase, whichever comes first.

If you open a door, everything will go off. And, after 10 minutes everything will go off, also. If you want power for another 10 minutes, just turn the key to Run and then back to Off. FUSES AlvD CIRCUIT BREAKERS The wiring circuits in your vehicle are protected from short circuits by a combination of Mini Fuses, Circuit Breakers, and Maxi Fuses. This greatly reduces the chance of fires caused by electrical problems. If you have a problem on the road and don’t have a spare fuse, you can “borrow” one of the same value. Select a feature that you can get along without that is the same value you need -- like the radio or cigarette lighter -- and use its fuse. Be sure to use a fuse with the same amperage rating number on it (ie. lOA, 20A, etc.) Replace it as soon as you can.

There is a fuse removal tool and some spare mini fuses in the glove box door, just lift the cover up.

Headlights The headlight wiring is protected by a circuit breaker in the light switch. An electrical overload will cause the lights to go on and off, or in some cases to remain off. If this happens, have your headlight wiring checked right away. Windshield Wipers The windshield wiper motor is protected by a circuit breaker and a fuse. If the motor overheats due to heavy snow, etc., the wiper will stop until the motor cools. If the overload is caused by some electrical problem and not snow, etc., be sure to get it fixed. rower Windows and Other Power Options Circuit breakers in the fuse panel protect the power windows and other power accessories. When the current load is too heavy, the circuit breaker opens and closes, protecting the circuit until the problem is fixed or goes away. BULB C I T

SPECIFICATIONS 4.6L 32 Valve (DOHC) Northstar Engine

19

The engine is a 4.6 liter (279 cu.in.) 90' V-8 featuring Dual Overhead Cam (DOHC), 32 valve, and sequential port fuel injection. This design results in a powerful, refined engine which is well suited to even the most demanding driving conditions. Engine weight is minimized by the use of low mass alloy materials. The crankcase, cylinder heads and oil pan are made from cast aluminum. The induction system housing, cam covers and oil filter adapter are cast magnesium. The reduced engine mass enhances vehicle handling and responsiveness.

336

The Northstar engine is designed to require less maintenance than many other DOHC V-8 engines. Engine systems are designed to remind the driver when service is required. An oil life index indicator monitors ongoing operating conditions and reminds the driver when an oil change is needed. A low coolant warning message keeps track of the level of this vital fluid. Direct acting hydraulic tappets provide maintenance free zero lash operation of the 32 valves from idle to the 6500 rpm redline. The camshafts are driven by a two stage roller chain assembly which is designed to provide quiet maintenance free operation. Platinum tipped spark plugs increase the replacement interval to 100,OO miles. The four valve per cylinder design provides more efficient engine breathing which results in higher power than comparable two valve engines. The central location of each spark plug ensures a fast and complete burning of the fuel/air mixture. The induction system uses smooth thermoplastic tubes to channel air into the cylinders. The smoothness of the tubes is equivalent to the elaborate port polishing methods used for race car engines. Careful design using the shape and length of the tubes boosts horsepower by using sonic pressure waves created by the motion of the inlet valves to increase the amount of air entering each cylinder. The Northstar engine is also designed to be very durable. The aluminum block has cast-in-place iron cylinder liners for greater wear resistance. High strength forged steel connecting rods support the free floating piston pins in bronze bushings for superior high speed performance. The fillits of the nodular iron crankshaft undergo a high pressure compression rolling operation to improve their resistance to fatigue. Quiet operation is enhanced by the use of special materials and designs. The front cover of the engine is stamped from laminated steel which damps out noise. Special cam cover gasket seals isolate valve train operation. The fuel injectors are placed inside the induction system housing to eliminate the clicking noise which is common to other fuel injected engines. The Northstar engine is designed to provide years of efficient, reliable, satisfying operation. We think it is also just plain fun to drive.

33 7

4.9 LITER ENGINE

The 4.9 Liter transverse engine is an overhead valve, 90 degree V-8 design. The cylinder bore diameter and the piston stroke provide a piston

- displacement of 4.9 liters (300 cubic inches).

This engine utilizes an aluminum crankcase with a separate aluminum lifter carrier and removable cast iron cylinder liners. The cylinder heads are made of cast iron and feature integral valve seats and guides. The cast nodular iron crankshaft is supported at five main bearing journals by cast iron main bearing caps and shell type steel-backed aluminum inserts. The center main bearing is the thrust bearing.

338

The cast aluminum pistons use two compression rings and one oil control ring. The pistons are tin plated to provide a non-scuffing surface when the engine is new. A steel camshaft is supported by five steel backed babbit bearings. It is driven by the crankshaft through a chain at the front of the engine. The drive gear is keyed to the crankshaft and the driven sprocket is bolted to the camshaft. Both the crankshaft gear and camshaft sprocket have locating marks to provide the correct valve timing and timing chain installation. The valve lifters are roller hydraulic type and are positioned in the aluminum lifter carrier. 4T80-E Transaxle (STS)

The 4T80-E transaxle has been designed to complement the output characteristics of the Northstar engine. The innovative design incorporates several features which enhance its overall operation.

339

This transaxle is the first of a new generation of “SMART” transmissions. The computer which controls the electronic shift solenoids adapts to changing environments while you drive. This provides consistent high quality shifts under all conditions. Communication between the engine and transaxle through this computer controls engine output during activation of torque management or traction control. Smooth shifting is ensured by design. Hydraulic accumulators control shift pressures and all shifts are made to free wheeling elements. The 4T80E uses a dry sump lubrication system with a scavenger pump. This unique feature enables the transaxlc to maintain itdcqlriltt! pressurized oil supply during a l l mancl~vcr\.

340

a control

The Hydra-matic 4T60-E 4-speed overdrive, electronic transaxle consists primarily of a five element torque converter; two planetary gear sets, various clutches, final drive assembly, differential assembly, and valve body. The torque converter houses a pump, turbine, pressure plate which is splined to the turbine, and a stator assembly, serving as a fluid coupling, it smoothly transmits power from the engine to the transaxle. It also hydraulically provides additional torque when required. When applied, the pressure plate provides a mechanical direct drive coupling of the engine to the transaxle. The two planetary gear sets provide the four forward gear ratios and reverse. Changing of the gear ratios is fully automatic and is accomplished through the use of various electronic and mechanical requirements. Four multiple disc clutches, two roller clutches, a sprag clutch, and three bands provide the friction elements required to obtain the various ratios with the planetary gear sets. A hydraulic system (the control valve body), pressurized by a vane type pump provides the working pressure needed elements and automatic controls.

to operate the friction

341

Front Suspension

Your fully independent front suspension is a combination strut and s p ~ -ing design. The frame is isolated from the body with six rubber mounts. Rubber bushings are used at the lower control arm pivots. The upper end of the strut is isolated by a rubber mount which contains a bearing to allow for wheel turning. The Road Sensing Suspension on the STS and the Speed Sensing Suspension on Seville will automatically controls the damping rate of the struts. The lower end of the steering knuckle pivots on a ball joint riveted to the control arm. The ball joint is connected to the steering knuckle with a castellated nut and cotter pin.

342

ShortlLong Arm Suspension (SLA)

Your vehicle uses an independent shortfiong arm rear suspension. All the rear suspension components are mounted on a suspension support which is attached to the body at four points and is fully isolated with bushings and insulators to minimize road noise. Each rear wheel is connected to the suspension support through the suspension knuckle using an upper and lower control arm and toe link. The control arms and toe link are attached to the suspension support on the inboard side, and to a suspension knuckle on the outboard side. The hub and bearing assembly is mounted to the knuckle and is a single, non- serviceable unit which eliminates the need for wheel bearing adjustment. The load leveling (ELC) shock absorbers are attached to the lower control arm, with the upper end of the shock attached to the suspension support. The springs are held in position between the lower control arms and a pocket in the suspension support. The suspension system also incorporates a new damping system now as Road Sensing Suspension on the STS and Speed Sensing suspension on

343

in the shock

the Seville. These systems control the damping forces absorbers and struts, in response to various road and driving conditions. The systems are capable of making these damping changes extremely fast. A computer receives inputs from vertical acceleration sensors, wheel to body position sensors, vehicle speed sensor, lift and dive signals. This computer evaluates the inputs from these sensors, of each of the struts and shocks independently to provide varied levels of suspension control. The system also has the capability of providing Speed Sensitive Steering control. This system changes your steering effort based on your vehicle speed. Speed Sensitive Steering

to control the damping

This system varies the amount of steering effort proportionate vehicle speed. Steering is easier at a lower speed for increased maneuverability and parking ease. As your vehicle speed increases, the steering effort is also increased to provide a manual like steering feel for maximum control and enhanced vehicle stability.

344

The power rack and pinion steering system has a rotary spool valve which directs hydraulic fluid coming from the power steering pump to one side or the other side of the rack piston. The integral rack piston is attached to the rack. The rack piston converts hydraulic pressure to a linear force which moves the rack left or right. The force is then transmitted through the inner and outer tie rods to the steering knuckles, which turn the wheels If hydraulic assist is not available, manual control is maintained. However under these conditions more steering effort is required.
