1996 Cadillac Seville Owners Manual

wheel assemblies and tires are forced to work harder against the drag of the added weight. The engine is required to operate at relatively higher speeds and under greater loads, generating extra heat. What’s more, the trailer adds considerably to wind resistance, increasing the pulling requirements.

If You Do Decide To Pull A Trailer If you do, here are some important points.

There are many different laws, including speed limit restrictions, having to do with trailering. Make sure your rig will be legal, not only where you live but also where you’ll be driving. A good source for this information can be state or provincial police. Consider using a sway control. You can ask a hitch dealer about sway controls. Don’t tow a trailer at all during the first 1,000 miles (1 600 k m ) your new vehicle is driven. Your engine, axle or other parts could be damaged. Then, during the first 500 miles (800 km) that you tow a trailer, don’t drive over SO mph (80 km/h) and don’t make starts at full throttle. This helps your engine and other parts of your vehicle wear in at the heavier loads. Obey speed limit restrictions when towing a trailer. Don’t drive faster than the maximum posted speed for trailers (or no more than 55 mph (90 km/h)) to save wear on your vehicle’s parts.

Three important considerations have to do with weight: the weight of the trailer, the weight of the trailer tongue and the total weight on your vehicle’s tires. Weight of the Trailer How heavy can a trailer safely be? It should never weigh more than 1,000 lbs. (450 kg) total, including the load. But even that can be too heavy. It depends on how you plan to use your rig. For example, speed, altitude, road grades, outside temperature and how much your vehicle is used to pull a trailer are all important. And, it can also depend on any special equipment that you have on your vehicle. You can ask your dealer for our trailering information or advice, or you can write us at:

In Canada, write to:

General Motors of Canada Limited Customer Assistance Center 1908 Colonel Sam Drive Oshawa, Ontario L1H 8P7

Weight of the Trailer Tongue The tongue load (A) of any trailer is an important weight to measure because it affects the total capacity weight of your vehicle. The capacity weight includes the curb weight of the vehicle, any cargo you may carry in it and the people who will be riding in the vehicle. And if you will tow a trailer, you must subtract the tongue load from your vehicle’s capacity weight because your vehicle will be carrying that weight, too. See “Loading Your Vehicle” in the Index for more information about your vehicle’s maximum load capacity.

4-33

If you’re using a “dead-weight” hitch, the trailer tongue (A) should weigh 10% of the total loaded trailer weight (B). If you have a “weight-distributing” hitch, the trailer tongue (A) should weigh 12% of the total loaded trailer weight (B). After you’ve loaded your trailer, weigh the trailer and then the tongue, separately, to see if the weights are proper. If they aren’t, you may be able to get them right simply by moving some items around in the trailer. Total Weight on Your Vehicle’s Tires Be sure your vehicle’s tires are inflated to the recommended pressure for cold tires. You’ll find these numbers on the Certification label at the rear edge of the driver’s door or see “Loading Your Vehicle” in the Index. Then be sure you don’t go over the GVW limit for your vehicle, including the weight of the trailer tongue.

Hitches It’s important to have the correct hitch equipment. Crosswinds, large trucks going by and rough roads are a few reasons why you’ll need the right hitch. Here are some rules to follow: 0 Will you have to make any holes in the body of your

vehicle when you install a trailer hitch? If you do, then be sure to seal the holes later when you remove the hitch. If you don’t seal them, deadly carbon monoxide (CO) from your exhaust can get into your vehicle (see “Carbon Monoxide” in the Index). Dirt and water can, too. The bumpers on your vehicle are not intended for hitches. Do not attach rental hitches or other bumper-type hitches to them. Use only a frame-mounted hitch that does not attach to the bumper.

4-34

Safety Chains You should always attach chains between your vehicle and your trailer. Cross the safety chains under the tongue of the trailer so that the tongue will not drop to the road if it becomes separated from the hitch. Instructions about safety chains may be provided by the hitch manufacturer or by the trailer manufacturer. Follow the manufacturer’s recommendation for attaching safety chains and do not attach them to the bumper. Always leave just enough slack so you can turn with your rig. And, never allow safety chains to drag on the ground. Trailer Brakes Because you have anti-lock brakes, don’t try to tap into your vehicle’s hydraulic brake system. If you do, both brake systems won’t work well, or at all. Be sure to read and follow the instructions for the trailer brakes so you’ll be able to install, adjust and maintain them properly.

Driving with a nailer Towing a trailer requires a certainanount of experience. Before setting out for the open road, you’ll want to get to know your rig. Acquaint yourself with the feel of handling and braking with the added weight of the trailer. And always keep in mind that the vehicle you are driving is now a good deal longer and not nearly as responsive as your vehicle is by itself. Before you start, check the trailer hitch and platform (and attachments), safety chains, electrical connector, lamps, tires and mirror adjustment. If the trailer has electric brakes, start your vehicle and trailer moving and then apply the trailer brake controller by hand to be sure the brakes are working. This lets you check your electrical connection at the same time. During your trip, check occasionally to be sure that the load is secure, and that the lamps and any trailer brakes are still working.

LI

4-35

Following Distance Stay at least twice as far behind the vehicle ahead as you would when driving your vehicle without a trailer. This can help you avoid situations that require heavy braking and sudden turns. Passing You’ll need more passing distance up ahead when you’re towing a trailer. And, because you’re a good deal longer, you’ll need to go much farther beyond the passed vehicle before you can return to your lane. Backing Up Hold the bottom of the steering wheel with one hand. Then, to move the trailer to the left, just move that hand to the left. To move the trailer to the right, move your hand to the right. Always back up slowly and, if possible, have someone guide you.

Making Thrns

I NOTICE:

Making very sharp turns while trailering could cause the trailer to come in contact with the vehicle. Your vehicle could be damaged. Avoid making very sharp turns while trailering.

~~

When you’re turning with a trailer, make wider turns than normal. Do this so your trailer won’t strike soft shoulders, curbs, road signs, trees or other objects. Avoid jerky or sudden maneuvers. Signal well in advance.

4-36

Turn Signals When Towing a Trailer When you tow a trailer, your vehicle may need a different turn signal flasher and extra wiring. Check with your Cadillac dealer. The green arrows on your instrument panel will flash whenever you signal a turn or lane change. Properly hooked up, the trailer lamps will also flash, telling other drivers you’re about to turn, change lanes or stop. When towing a trailer, the green arrows on your instrument panel will flash for turns even if the bulbs on the trailer are burned out. Thus, you may think drivers behind you are seeing your signal when they are not. It’s important to check occasionally to be sure the trailer bulbs are still working. Driving On Grades Reduce speed and shift to a lower gear before you start down a long or steep downgrade. If you don’t shift down, you might have to use your brakes so much that they would get hot and no longer work well. On a long uphill grade, shift down and reduce your speed to around 45 mph (70 km/h) or less to reduce the possibility of engine and transaxle overheating.

L.

Parking on Hills You really should not park your vehicle, with a trailer attached, on a hill. If something goes wrong, your rig could start to move. People can be injured, and both your vehicle and the trailer can be damaged. But if you ever have to park your rig on a hill, here’s how to do it: 1.

Apply your regular brakes, but do not shift into PARK (P). Have someone place chocks under the trailer wheels. When the wheel chocks are in place, release the regular brakes until the chocks absorb the load. Reapply the regular brakes. Then shift into PARK (P) firmly and apply your parking brake. Release the regular brakes.

When You Are Ready to Leave After Parking on a Hill 1. Apply your regular brakes and hold the pedal down

while you:

Start your engine; Shift into a gear; and Be sure the parking brake has released.

2. Let up on the brake pedal. 3. Drive slowly until the trailer is clear of the chocks. 4. Stop and have someone pick up and store the chocks.

Maintenance When Trailer Towing Your vehicle will need service more often when you’re pulling a trailer. See the Maintenance Schedule for more on this. Things that are especially important in trailer operation are automatic transaxle fluid (don’t overfill), engine oil, belt, cooling system and brake adjustment. Each of these is covered in this manual, and the Index will help you find them quickly. If you’re trailering, it’s a good idea to review these sections before you start your trip. Check periodically to see that all hitch nuts and bolts are tight.

Section 5 Problems on the Road

Here you'll find what to do about some problems that can occur on the road. Hazard Warning Flashers

Your hazard warning flashers let you warn others. They also let police know you have a problem. Your front and rear turn signal lamps will flash on and off.

Press the button in to make the front and rear turn signal lamps flash on and off.

5-1

A This light on the instrument

panel will flash indicating that the hazard warning flashers are on.

The hazard warning fiashers will work once the button is pressed in regardless of the key position.

.-

Pull out on the collar to turn the flashers off. When the hazard warning flashers are on, the turn signals won't work since they are already flashing.

Other Warning Devices If you carry reflective triangles, you can set one up at the side of the road about 300 feet (100 m) behind your vehicle. Jump Starting If your battery has run down, you may want to use another vehicle and some jumper cables to start your Cadillac. Please follow the steps below to do it safely.

NOTICE:

in costly damage Ignoring these steps could result to your vehicle that wouldn’t be covered by your warranty. Trying to start your Cadillac by pushing or pulling it won’t work and it could damage your vehicle.

A CAUTION:

Batteries can hurt you. They can be dangerous because: 0 They contain acid that can burn you. 0 They contain gas that can explode or ignite. 0 They contain enough electricity to burn you. If you don’t follow these steps exactly, some or all of these things can hurt you.

Get the’vehicles close enough so the jumper cables can reach, but be sure the vehicles aren’t touching each other. If they are, it could cause a ground connection you don’t want. You wouldn’t be able to start your Cadillac and the bad grounding could damage the electrical systems. Turn off the ignition on both vehicles. Unplug unnecessary accessories plugged into the cigarette lighter. Turn off all lamps that aren’t needed as well as radios. This will avoid sparks and help save both batteries. In addition, it could save your radio! Open the hoods and locate the batteries. Find the positive (+) and negative (-) terminals on each battery.

I A CAUTION:

Using a match near a battery can cause battery gas to explode. People have been hurt doing this, and some have been blinded. Use a flashlight if you need more light. Be sure the battery has enough water. You don’t need to add water to the Delco Freedom@ battery installed in every new GM vehicle. But if a battery has filler caps, be sure the right amount -of fluid is there. If it is low, add water to take care of that first. If you don’t, explosive gas could be present. Battery fluid contains acid that can burn you. Don’t get it on you. If you accidentally get it in your eyes or on your skin, flush the place with water and get medical help immediately.

6. Check that the jumper cables don’t have loose or

missing insulation. If they do, you could get a shock. The vehicles could also be damaged. Before you connect the cables, here are some’ things you should know. Positive (+) will go to positive (+) and negative (-) will go to negative (-) or a metal engine part. Don’t connect positive (+) to negative (-) or you’ll get a short that would damage the battery and maybe other parts, too.

A CAUTION:

Fans or other moving engine parts can injure you badly. Keep your hands away from moving parts once the engines are running.

7. Connect the red positive (+) cable to the positive (+)

terminal of the vehicle with the dead battery.

8. Don't let the other end of the positive cable touch metal. Connect it to the positive. (+) terminal of the good battery.

9. Now connect the black

negative (-) cable to the good battery's negative (-) terminal.

Don't let the other end of the negative (-) cable touch anything until the next step. The other end of the negative (-) cable doesn't go to the dead battery. It goes to a heavy unpainted metal part on the engine of the vehicle with the dead battery.

13. Remove the cables in reverse order to prevent

electrical shorting. Take care that they don't touch each other or any other metal.

I 10. Attach the cable at least 18 inches (45 cm) away from the dead battery, but not near engine parts that move. The electrical connection is just as good there, but the chance of sparks getting back to the battery is much less.

11. Now start the vehicle with the good battery and run

the engine for awhile.

12. Try to start the vehicle with the dead battery. If it

won't start after a few tries, it probably needs service.

Towing Your Vehicle Try to have a Cadillac dealer or a professional towing service tow your Seville. See “Roadside Assistance” in the Index. If your vehicle has been changed or modified since it was factory-new by adding aftermarket items like fog lamps, aero skirting or special tires and wheels, these instructions may not be correct. Before you do anything, turn on the hazard warning flashers. When you call, tell the towing service: 0 That your vehicle has front-wheel drive.

The make, model and year of your vehicle. 0 Whether you can still move the shift lever. 0 If there was an accident, what was damaged. When the towing service arrives, let the tow operator know that this manual contains towing instructions and illustrations. The operator may want to see them.

Rear Towing

To help avoid injury to you or others:

Never let passengers ride in a vehicle that is being towed. Never tow faster than safe or posted speeds. Never tow with damaged parts not fully secured. Never get under your vehicle after it has been lifted by the tow truck. Always secure the vehicle on each side with separate safety chains when towing it. Never use J-hooks. Use only T-hooks in the front T-hook slots and only R-hooks in the rear R-hook slots.

5-9

A CAUTION:

A vehicle can fa11 from a car carrier if it isn’t adequately secured. This can cause a collision, serious personal injury and vehicle damage. The vehicle should be tightly secured with chains or steel cables before it is transported. Don’t use substitutes (ropes, leather straps, canvas webbing, etc.) that can be cut by sharp edges underneath the towed vehicle. Always use T-hooks inserted in the front T-hook slots or R-hooks inserted in the rear R-hook slots. Never use J-hooks. They will damage drivetrain and suspension components.

When your vehicle is being towed, have the ignition key turned to the OFF position. The steering wheel should be clamped in a straight-ahead position, with a clamping device designed for towing service. Do not use the vehicle’s steering column lock for this. The transaxle should be in NEUTRAL (N) and the parking brake released. Don’t have your vehicle towed on the drive wheels unless you must. If the vehicle must be towed on the drive wheels, be sure to follow the speed and .distance restrictions later in this section or your transaxle will be damaged. If these limitations must be exceeded, then the drive wheels have to be supported on a dolly.

Engine Overheating You will find an ENGINE COOLANT HOT-IDLE ENGINE message or a STOP ENGINE ENGINE OVERHEATED message on the Driver Information Center. There is also an engine temperature warning light on the instrument panel. See “Engine Temperature Warning Light” in the Index. Overheated Engine Protecaon Operating Mode Should a low coolant condition exist and the message STOP ENGINE ENGINE OVERHEATED is displayed, an overheat protection mode which alternates firing groups of four cylinders helps prevent engine damage. This operating mode allows your vehicle to be driven to a safe place in an emergency; you may drive up to 50 miles (80 km). Towing a trailer in the overheat protection mode should be avoided.

NOTICE:

After driving in the Overheated Engine Protection Operating Mode, to avoid engine damage, allow the engine to cool before attempting any repair. The engine oil may be severely degraded. Change the oil and reset the oil life indicator. See “Engine Oil, When to Change” in the Index.

5-15

If Steam Is Coming From Your Engine

A CAUTION:

Stcam from an overheated engine can burn you badly, even if you just open the hood. Stay away from the engine if you see or hear steam coming from it. Just turn it off and get everyone away from the vehicle until it cools down. Wait until there is no sign of steam or coolant before opening the hood. If you keep driving when your engine is You overheated, the liquids in it can catch fire. or others could be badly burned. Stop your engine if it overheats, and get out of the vehicle until the engine is cool.

NOTICE:

If your engine catches fire because you keep driving with no coolant, your vehicle can be badly damaged. The costly repairs would not be covered by your warranty. See “Overheated Engine Protection Operating Mode” in the Index.

5-16

If No Steam Is Coming From Your Engine If you get the overheat warning but see or hear no steam, the problem may not be too serious. Sometimes the engine can get a little too hot when you: 0 Climb a long hill on a hot day. Stop after high-speed driving. Idle for long periods in traffic.

0 Tow a trailer. If you get the overheat warning with no sign of steam, try this for a minute or so: 1. Turn off your air conditioner. 2. Dial temperature control to the highest heat setting

and open the window, as necessary.

3. If you’re in a traffic jam, shift to NEUTRAL (N);

otherwise, shift to the highest gear while driving -- OVERDRIVE (a) or THIRD (3).

rc

.-,

If you no longer have the overheat warning, you can drive. Just to be safe, drive slower for about 10 minutes. If the warning doesn’t come back on, you can drive normally. If the warning continues, pull over, stop and park your vehicle right away. If there’s still no sign of steam, you can idle the engine for two or three minutes while you’re parked, to see if the warning stops. But then, if you still have the warning, turn oflthe engine and get everyone out of the vehicle until it cools down. Also, see “Overheated Engine Protection Operating Mode” listed previously in this section. You may decide not to lift the hood but to get service help right away.

I A CAUTION:

An electric fan under the hood can start PIP even when the engine is not running and can injure you. Keep hands, clothing and tools away from any underhood electric fan.

If the coolant inside the coolant surge tank is boiling, don't do anything else until it cools down.

When you decide it's safe to lift the hood, here's what you'll see: A. Coolant Surge Tank with Pressure Cap B. Electric Engine Fans

-,. .

The coolant level should be indicated by a CHECK COOLANT LEVEL message on the Driver Information Center. If it isn't, you may have a leak in the radiator hoses, heater hoses, radiator, water pump or somewhere else in the cooling system.

A CAUTION:

Heater and radiator hoses, and other engine parts, can be very hot. Don't touch them. If you do, you can be burned. Don't run the engine if there is a leak. If you run the engine, it could lose all coolant. That could cause an engine fire, and you could be burned. Get any leak fixed before you drive the vehicle.

5-19

I NOTICE:

Engine damage if you keep running your engine without coolant isn’t covered by your warranty. See “Overheated Engine Protection Operating Mode’? in the Index.

If there seems to be no leak, with the engine on, check to see if the electric engine fans are running. If the engine is overheating, both fans should be running. If they aren’t, your vehicle needs service.

How to Add Coolant to the Coolant Surge Tank If you haven’t found a problem yet, but the coolant level isn’t at the proper level (2.5 inches (60 mm) below the base of the fill neck), add a 50/50 mixture of clean water (preferably distilled) and DEX-COOL TM antifreeze at the coolant surge tank, but be sure the cooling system, including the coolant surge tank pressure cap, is cool before you do it. (See “Engine Coolant” in the Index for more information.)

A CAUTION:

Steam and scalding liquids from a hot cooling system can blow out and burn you badly. They are under pressure, and if you turn the coolant surge

tank pressure cap -- even a little -- they can come

out at high speed. Never turn the cap when the cooling system, including the coolant surge tank pressure cap, is hot. Wait for the cooling system and coolant surge tank pressure cap to cool if you ever have to turn the pressure cap.

5-20

:?.

,il

I A CAUTION:

j 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 50150 mix of clean water and DEX-COOL R*l antifreeze.

5-21

NOTICE:

In cold weather, water can freeze and crack the engine, radiator, heater core and other parts. So use the recommended coolant.

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.

5-22

1. You can remove the coolant surge tank pressure

cap when the cooling system, including the coolant surge tank pressure cap and upper radiator hose, is no longer hot. Turn the pressure cap slowly counterclockwise until it first stops. (Don’t press down while turning the pressure cap.) If you hear a hiss, wait for that to stop. A hiss means there is still some pressure left.

2. Then keep turning the cap, but now push down as

you turn it. Remove the pressure cap.

3. Then fill the coolant surge tank with the proper mix,

up to the base of the filler neck.

5-23

4. With the coolant surge tank pressure cap off, start the

engine and let it run until you can feel the upper radiator hose getting hot. Watch out for the engine fans. By this time, the coolant level inside the coolant surge tank may be lower. If the level is lower, add more of the proper mix to the coolant surge tank until the level reaches about 2.5 inches (60 mm) below the base of the filler neck.

S. Then replace the pressure cap. Be sure the arrows on

the pressure cap line up like this.

Start the engine and allow it to warm up. If the CHECK COOLANT LEVEL message does not appear on the Driver Information Center, coolant is at the proper fill level. If a CHECK COOLANT LEVEL message does appear, repeat Steps 1 to 3 or see your dealer.

If a Tire Goes Flat It’s unusual for a tire to “blow out” while you’re driving, especially if you maintain your tires properly. If air goes out of a tire, it’s much more likely to leak out slowly. But if you should ever have a “blowout,” here are a few tips about what to expect and what to do: If a front tire fails, the flat tire will create a drag that pulls the vehicle toward that side. Take your foot off the accelerator pedal and grip the steering wheel firmly. Steer to maintain lane position, and then gently brake to a stop well out of the traffic lane. A rear blowout, particularly on a curve, acts much like a skid and may require the same correction you’d use in a skid. In any rear blowout, remove your foot from the accelerator pedal. Get the vehicle under control by steering the way you want the vehicle to go. It may be very bumpy and noisy, but you can still steer. Gently brake to a stop -- well off the road if possible. If a tire goes flat, the next part shows how to use your jacking equipment to change a flat tire safely.

Changing a Flat Tire If a tire goes flat, avoid further tire and wheel damage by driving slowly to a level place. Turn on your hazard warning flashers.

A CAUTION:

Changing a tire can cause an injury. The vehicle can slip off the jack and roll over you or other people. You and they could be badly injured. Find a level place to change your tire. To help prevent the vehicle from moving:

1. Put the shift lever in PARK (P). 2. Set the parking brake firmly. 3. Turn off the engine.

To be even more certain the vehicle won’t move, you can put blocks at the front and rear of the tire farthest away from the one being changed. That would be the tire on the other side of the vehicle, at the opposite end.

Removing the Spare Tire and Tools

The following steps will tell you how to use the jack and change a tire.

The equipment you’ll need is in the trunk. Pull the carpeting from the floor of the trunk. Turn the center dial on the compact spare cover counterclockwise to remove it. Lift and remove the cover. (See “Compact Spare Tire” later in this section for more information about the compact spare.)

5-26

c

Lift up the tire to remove it from the trunk.

Turn the nut holding the jack and wheel wrench counterclockwise and remove it. Then remove the jack and wrench.

5-27

Removing the Wheel Cover

The tools you'll be using include the jack (A) and the wheel wrench (B).

There is a center wheel cover on the aluminum wheel. Using the flat end of the wheel wrench, gently pry the wheel cover off. Be careful not to scratch the aluminum wheel edge and don't try to remove it with your hands.

Removing the Flat Tire and Installing the Spare Tire

A CAUTION:

Getting under a vehicle when it is jacked up is dangerous. If the vehicle slips off the jack, you could be badly injured or killed. Never get under a vehicle when it is supported only by a jack.

NOTICE:

c-

1. Using the wheel wrench, loosen all the wheel nuts.

Don't remove them yet.

2. Turn the jack handle clockwise to raise the jack lift

head a few inches.

Raising your vehicle with the jack improperly positioned will damage the vehicle or may allow the vehicle to fall off the jack. Be sure to fit the jack lift head into the proper location before raising your vehicle.

3. Position the jack under the vehicle and raise the jack

lift head until it fits firmly into the notch in the vehicle's frame nearest the flat tire. Put the compact spare tire near you.

4. Raise the vehicle by turning the jack handle

clockwise. Raise the vehicle far enough off the ground for'the spare tire to fit under the vehicle. 5. Remove all wheel nuts and take off the flat tire.

6. Remove any rust or dirt from the wheel bolts, mounting surfaces and spare wheel.

A CAUTION:

Rust or dirt on the wheel, or on the parts to which it is fastened, can make the 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 the 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.

A CAUTION:

~~

Never use oil or grease on studs or nuts. If you do, the nuts might come loose. Your wheel could fali off, causing a serious accident.

7. Replace the wheel

nuts with the rounded end of the nuts toward the wheel. Tighten each nut by hand until the wheel is held against the hub.

5-31

-

9. Tighten the

wheel nuts firmly in a criss-cross sequence as shown.

A CAUTION:

Incorrect wheel nuts or improperly tightened wheel nuts can cause the wheel to become loose and even come off. This could lead to an accident. Be sure to use the correct wheel nuts. If you have to replace them, be sure to get the right kind. Stop somewhere as soon as you can and have the nuts tightened with a torque wrench to 100 lb-ft (140 N-m).

8. Lower the vehicle by turning the jack hanale counterclockwise. Lower the jack completely.

5-32

c

NOTICE:

Improperly tightened wheel nuts can lead to brake pulsation and rotor damage. To avoid expensive brake repairs, evenly tighten the wheel nuts in the proper sequence and to the proper torque specification.

Don’t try to put a wheel cover on your compact spare tire. It won’t fit. Store the wheel cover in the trunk until you have the flat tire repaired or replaced.

NOTICE:

Wheel covers won’t fit on your compact spare. If you try to put a wheel cover on your compact spare, you could damage the cover or the spare.

Storing the Flat Tire and Tools

CAUTION:

Storing a jack, a tire or other equipment in the passenger compartment of the vehicle could cause injury. In a sudden stop or collision, loose equipment could strike someone. Store all these in the proper place.

After you’ve put the compact spare tire on your vehicle, you’ll need to store the flat tire in your trunk. Use the following procedure to secure the flat tire in the trunk. Put the flat tire in the trunk so the side that faces out when it is on the vehicle is facing down. The full-size tire will not fit down into the well. Place it so the front is in the well and the rear is out of the well.

5-33

Secure the tire with the stud cap that was used to hold the. compact spare in place. Store the cover as far forward as possible.

Storing the Spare Tire and Tools

I A CAUTION:

Storing a jack, a tire or other equipment in the passenger compartment of the vehicle could cause injury. In a sudden stop or coilision, loose equipment could strike someone. Store all these in the proper place.

The compact spare is for temporary use only. Replace the compact spare tire with a full-size tire as soon as you can. See the storage instructions label to replace your compact spare into your trunk properly.

Compact Spare Tire Although the compact spare tire was fully inflated when your vehicle was new, it can lose air after a time. Check the inflation pressure regularly. It should be 60 psi (420 kPa). After installing the compact spare on your vehicle, you should stop as soon as possible and make sure your spare tire is correctly inflated. The compact spare. is made to perform well at posted speed limits for distances up to 3,000 miles (5 000 km), so you can finish your trip and have your full-size tire repaired or replaced where you want. Of course, it’s best to replace your spare with a full-size tire as soon as you can. Your spare will last longer and be in good shape in case you need it again.

5-35

If You’re Stuck: In Sand, Mud, Ice or Snow What you don’t want to do when your vehicle is-stuck is to spin your wheels too fast. The method known as “rocking’’ can help you get out when you’re stuck, but you must use caution.

A CAUTION:

If you let your tires spin at high speed, they can explode, and you or others could be injured. And, the transaxle or other parts of the vehicle can overheat. That could cause an engine compartment fire or other damage. When you’re stuck, spin the wheels as little as possible. Don’t spin the wheels above 35 mph (55 k d h ) as shown on the speedometer.

NOTICE:

When the compact spare is installed, don’t take your vehicle through an automatic car wash with guide rails. The compact spare can get caught on the rails. That can damage the tire and wheel, and maybe other parts of your vehicle.

Don’t use your compact spare on other vehicles. And don’t mix your compact spare tire or wheel with other wheels or tires. They won’t fit. Keep your spare tire and its wheel together.

NOTICE:

Tire chains won’t fit your compact spare. Using them can damage your vehicle and can damage the chains too. Don’t use tire chains on your compact spare.

5-36

c

NOTICE:

Spinning your wheels can destroy parts of your vehicle as well as the tires. If you spin the wheels too fast while shifting your transaxle back and forth, you can destroy your transaxle.

For information about using tire chains on your vehicle, see “Tire Chains” in the Index.

Rocking your vehicle to get it out: First, turn your steering wheel left and right. That will clear the area around your front wheels. You should turn your traction control system off. (See “Traction Control System” in the Index.) Then shift back and forth between REVERSE (R) and a forward gear, spinning the wheels as little as possible. Release the accelerator pedal while you shift, and press lightly on the accelerator pedal when the transaxle is in gear. If that doesn’t get you out after a few tries, you may need to be towed out. If you do need to be towed out, see “Towing Your Vehicle” in the Index.

Doing Your Own Service Work If you want to do some of your own service work, you’ll want to get the proper Cadillac service manual. It tells you much more about how to service your Cadillac than this manual can. To order the proper service manual, see ”Service and Owner Publications” in the Index. Your vehicle has an air bag system. Before attempting to do your own service work, see ”Servicing Your Air Bag-Equipped Cadillac” in the Index. You should keep a record with all parts receipts and list the mileage and the date of any service work you perform. See “Maintenance Record” in the Maintenance Schedule booklet.

6-1

I A CAUTION:

I - - -

You can be injured and your vehicle could be damaged if you try to do service work on a vehicle without knowing enough about it. 0 Be sure you have sufficient knowledge, experience, and the proper replacement parts and tools before you attempt any vehicle maintenance task.

0 Be sure to use the proper nuts, bolts and other fasteners. “English” and “metric” fasteners can be easily confused. If you use the wrong fasteners, parts can later break or fall off. You could be hurt.

Fuel Use premium unleaded gasoline rated at 91 octane or higher. At a minimum, it should meet specifications ASTM D4814 in the United States and CGSB 3.5-M93 in Canada. Improved gasoline specifications have been developed by the American Automobile Manufacturers Association (AAMA) for better vehicle performance and engine protection. Gasolines meeting the AAMA 6-2

specification could provide improved driveability and emission control system protection compared to other gasolines. Be sure the posted octane for premium is at leasf 9 1. If the octane is less than 91, you may get a heavy knocking noise when you drive. (In an emergency, you may be able to use a lower octane -- as low as 87 -- if heavy knocking does not occur.) If you’re using 91 or higher octane unleaded gasoline and you still hear heavy knocking, your engine needs service. If your vehicle is certified to meet California Emission Standards (indicated on the underhood tune-up label), it is designed to operate on fuels that meet California specifications. If such fuels are not available in states adopting California emissions standards, your vehicle will operate satisfactorily on fuels meeting federal specifications, but emission control system performance may be affected. The malfunction indicator lamp on your instrument panel may turn on and/or your vehicle may fail a smog-check test. If this occurs, return to your authorized Cadillac dealer for diagnosis to determine the cause of failure. In the event it is determined that the cause of the condition is the type of fuels used, repairs may not be covered by your warranty.

L-

In Canada, some gasolines contain an octane-enhancing additive called MMT. If you use such fuels, your emission control system performance may deteriorate and the malfunction indicator lamp on your instrument panel may turn on. If this happens, return to your authorized Cadillac dealer for service. To provide cleaner air, all gasolines are now required to contain additives that will help prevent deposits from forming in your engine and fuel system, allowing your emission control system to function properly. Therefore, you should not have to add anything to the fuel. In addition, gasolines containing oxygenates, such as ethers and ethanol, and reformulated gasolines may be available in your area to help clean the air. General Motors recommends that you use these gasolines if they comply with the specifications described earlier.

NOTICE:

Fuels in Foreign Countries If you plan on driving in another country outside the United States or Canada, the proper fuel may b.e hard to find. Never use leaded gasoline or any other fuel not recommended in the previous text on fuel. Costly repairs caused by use of improper fuel wouldn’t be covered by your warranty. To check on fuel availability, ask an auto club or contact a major oil company that does business in the country where you’ll be driving. You can also write us at the following address for advice. Just tell us where you’re going and give your Vehicle Identification Number (VIN).

Your vehicle was not designed for fuel that contains methanol. Don’t use it. It can corrode metal parts in your fuel system and also damage plastic and rubber parts. That damage wouldn’t be covered under your warranty.

Filling Your Tank

The fuel door release is located on the optional full console and on the Keyless Entry transmitter. If .your vehicle is not equipped with the full console, then you must use the transmitter to open the fuel door.

I An alternate fuel door release is located inside of the trunk on the left hand side. Pull it to release the fuel door.

. .

The cap is behind a hinged door on the driver's side of your vehicle.

A CAUTION:

Gasoline vapor is highly flammable. It burns violently, and that can cause very bad injuries. Don't smoke if you're near gasoline or refueling your vehicle. Keep sparks, flames and smoking materials away from gasoline.

6-4

Hang the cap inside the fuel door while refueling. To take off the cap, turn it slowly to the left (counterclockwise).

I A CAUTION:

If you get gasoline on yourself and then something ignites it, you could be badly burned. Gasoline can spray out on you if you open the fuel filler cap too quickly. This spray can happen if your tank is nearly full, and is more likely in hot weather. Open the fuel filler cap slowly and wait for any “hiss” noise to stop. Then unscrew the cap all the way.

Be careful not to spill gasoline. Clean gasoline from painted surfaces as soon as possible. See “Cleaning the Outside of Your Cadillac” in the Index.

6-5

When you put the cap back on, turn it to the right until you hear at least three clicks. Make sure you fully install the cap.

I NOTICE:

If you need a new cap, be sure to get the right type. Your dealer can get one for you. If you get the wrong type, it may not fit or have proper venting, and your fuel tank and emissions system might be damaged.

Checking Things Under the Hood A CAUTION:

. .

An electric fan under the hood can start up and injure you even when the engine is not running. Keep hands, clothing and tools away from any underhood electric fan.

A CAUTION:

Things that burn can get on hot engine parts and start a fire. These include liquids like gasoline, oil, coolant, brake fluid, windshield washer and other fluids, and plastic or rubber. You or others could be burned. Be careful not to drop or spill things that will burn onto a hot engine.

TRIP

A CHECK OIL LEVEL message will appear when the engine oil is approximately a quart low. If the message is displayed, check the dipstick level and add oil as needed. It's a good idea to check your engine oil every time you get fuel. In order to get an accurate reading, the oil must be warm and the vehicle must be on level ground.

The engine oil dipstick is located behind the radiator on the driver's side of the engine. The black .handle says ENGINE OIL on it. Turn off the engine and give the oil a few minutes to drain back into the oil pan. If you don't, the oil dipstick might not show the actual level.

6-9

Checking Engine Oil Pull out the dipstick and clean it with a paper towel or cloth, then push it back in all the way. Remove it again, keeping the tip down, and check the level.

When to Add Oil If the oil is at or below the ADD line, then you’ll need to add some oil. But you must use the right kind. This part explains what kind of oil to use. For crankcase capacity, see “Capacities and Specifications” in the Index.

NOTICE:

Don’t add too much oil. If your engine has so much oil that the oil level gets above the upper mark that shows the proper operating range, your engine could be damaged.

6-10

The oil fill cap is located behind the radiator on the passenger’s side of the engine. Turn the cap counterclockwise to remove.

What Kind of Oil to Use Oils recommended for your vehicle can be identified by looking for the “Starburst” symbol. This symbol indicates that the oil has been certified by the American Petroleum Institute (APT). Do not use any oil which does not carry this Starburst symbol.

Just fill it enough to put the level somewhere in the proper operating range. Push the dipstick all the way back in when you’re throtlgh.

..

_ - U you change your own oil, be sure you use oil that has the Starburst symbol on the front of the oil container. If you have your oil changed for you, be sure the oil put into your engine is American Petroleum Institute certified for gasoline engines.

You should also use the proper viscosity oil for your vehicle, as shown in the following chart:

6-11

I

RECOMMENDED SAE VISCOSIT! GRADE ENGINE OILS

FOR BEST FUEL ECONOMY AND COLD F------l6, SELECT THE LOWEST SAE VISCOSITY GRADE OIL FOR THE E L L Y I C ~ TEMPERATURE RANGE.

’

As shown in the chart, SAE 1OW-30 is best for your vehicle. However, you can use SAE 5W-30 if it’s going to be colder than 60°F (16” C) before your next oil change. When it’s very cold, you should use SAE 5W-30. These numbers on an oil container show its viscosity, or thickness. Do not use other viscosity oils, such as SAE 2OW-50.

GM Goodwrench@ oil meets all the requirements for your vehicle. Engine Oil Additives Don’t add anything to your oil. Your Cadillac dealer is ready to advise if you think something should be added.

When to Change Engine Oil Your Cadillac has an Oil Life Indicator. This feature will let you know when to change your oil and filter -- usually between 3,000 miles (5 000 km) and 7,500 miles (12 500 km) since your last oil change. Under severe conditions, the indicator may come on before 3,000 miles (5 000 km). Never drive your vehicle more than 7,500 miles (12 500 km) or 12 months, (whichever occurs first) without an oil change. The system won’t detect dust in the oil. So, if you drive in a dusty area, be sure to change your oil every 3,000 miles (5 000 km) or sooner if the CHANGE ENGINE OIL message comes on. Remember to reset the Oil Life Indicator when the oil has been changed. For more information, see “Oil Life Indicator’’ in the Index.

How to Reset the Oil Life Indicator After the oil has been changed, display the OIL LIFE LEFT message by pressing the INFORMATION button. Then press and hold the RESET button until the display shows “100.” This resets the oil life index. The message will remain off until the next oil change is needed. The percentage of oil life remaining may be checked at any

time by pressing the INFORMATION button several times until the OIL LIFE LEFT message appears. For more information on the Oil Life feature, see “Oil Life Indicator’’ in the Index. What to Do with Used Oil Did you know that used engine oil contains certain elements that may be unhealthy for your skin and could even cause cancer? Don’t let used oil stay on your skin for very long. Clean your skin and nails with soap and water, or a good hand cleaner. Wash or properly throw away clothing or rags containing used engine oil..(See the manufacturer’s warnings about the use and disposal of oil products.) Used oil can be a real threat to the environment. If you change your own oil, be sure to drain all free-flowing oil from the filter before disposal. Don’t ever dispose of oil by putting it in the trash, pouring it on the ground. into sewers, or into streams or bodies of water. Instead, recycle it by taking it to a place that collects used oil. If you have a problem properly disposing of your used oil, ask your dealer, a service station or a local recycling center for help.

Air Cleaner

1. Disconnect the Intake Air Temperature (IAT) sensor from the base of the air cleaner.

The air filter is located next to the windshield washer fluid reservoir on the driver's side of the engine. Be sure the engine has cooled before following these steps to replace the air filter:

2. With a screwdriver, loosen the air duct clamp, which is located at the mass airflow sensor end of the air duct.

6-14

3. Disconnect the air duct from the mass airflow sensor.

4. Unhook both air cleaner cover latches. One latch is located near the radiator hose (not shown) and the other latch is located next to the IAT sensor.

5. Pivot the air cleaner and air duct assembly towards

the front of the vehicle. Remove the cover.

6. Take out the air filter and remove anv loose debris that may be found laying in the air cieaner base.

7. Install a new air filter element. See “Normal

Maintenance Replacement Parts” in the Index.

3.

Follow these steps to reinstall the air cleaner assembly: .1 .

Slide the air cleaner lid into the slots in the front edge of the air cleaner base. Pivot the air cleaner cover and the air duct assembly downward. Make sure that both latches are secure and fully engaged. Reinstall the clean air duct over the mass airflow sensor. Make sure that the duct is secure around the entire outer edge of the sensor. Tighten the air duct clamp. Reconnect the IAT sensor.

4. 5. Refer to the Maintenance Schedule to determine when to replace the air filter. See “Scheduled Maintenance Services” in the Maintenance Schedule booklet.

1 A CAUTION:

Operating the engine with the air cleaner off can cause you or others to be burned. The air cleaner not only cleans the air, it stops flames if the engine backfires. If it isn’t there, and the engine backfires, you could be burned. Don’t drive with it off, and be careful working on the engine with the air cleaner off.

I NOTICE:

If the air cleaner is off, a backfire can cause a damaging engine fire. And, dirt can easily get into your engine, which will damage it. Always have the air cleaner in place when you’re driving.

6-16

Automatic Transaxle Fluid When to Check and Change A good time to check your automatic transaxle fluid level is when the engine oil is changed. Change both the fluid and filter every 50,000 miles (83 000 km) 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.

0 In hilly or mountainous terrain.

When doing frequent trailer towing.

0 Uses such as found in taxi, police or delivery service, If you do not use your vehicle under any of these conditions, the fluid and filter do not require changing. See “Scheduled Maintenance Services” in the Maintenance Schedule booklet.

How to Check Because this operation can be a little difficult, you may choose to have this done at your Cadillac dealership service department. If you do it yourself, be sure to follow all the instructions here, or you could get a false reading on the dipstick.

I NOTICE:

Too much or too little fluid can damage your transaxle. Too much can mean that some of the fluid could come out and fall on hot engine parts or exhaust system parts, starting a fire. Be sure to get an accurate reading if you check your transaxle fluid.

%‘ .

6-17

Wait at least 30 minutes before checking the transaxle fluid level if you have been driving:

When outside temperatures are above 90°F (32°C).

0 At high speed for quite a while.

In heavy traffic -- especially in hot weather. While pulling a trailer.

To get the right reading, the fluid should be at normal operating temperature, which is 180 O F to 200 OF (82°C to 93°C). driving about 15 miles (24 km) Get the vehicle warmed up by when outside temperatures are above 50°F (10°C). If it's colder than 50°F (lO"C), you may have to drive longer. Checking the Fluid Level 0 Park your vehicle on a level place. Keep the engine

running.

0 With the parking brake applied, place the shift lever

in PARK (P).

0 With your foot on the brake pedal, move the shift lever through each gear range, pausing for about three seconds in each range. Then, position the shift lever in PARK (P). Let the engine run at idle for three to five minutes.

6-18

Then, without shutting off the engine, follow

these steps:

1. The black transaxle fluid cap is located next to the radiator hose and below the air cleaner assembly on the driver's side of the engine. Remove the air cleaner assembly so you can reach the transaxle fluid cap, The assembly is attached to the vehicle by two fasteners. Simply lift up on the air cleaner assembly to remove it. Find the transaxle fluid cap and turn it counterclockwise to remove. Pull out the dipstick and wipe it with a clean rag or paper towel.

2. Push it back in all the way. wait three seconds and

then pull it back out again.

c

3-

3. Check both sides of the dipstick, and read the lower level. The fluidlevel must be in the cross-hatched area.

4. If the fluid level is in the acceptable range, push the

dipstick back in all the way.

5. Replace the air cleaner assembly. How to Add Fluid Refer to the Maintenance Schedule to determine what kind of transaxle fluid to use. See “Recommended Fluids and Lubricants” in the Maintenance Schedule booklet. 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. 1. Pull out the dipstick. 2. Using a long-neck funnel, add enough fluid at the

dipstick hole to bring it to the proper level. It doesn’t take much fluid, generally less than a pint (0.5 L).

Don’t overfX We recommend you use only fluid labeled DEXRON@-111, because fluid with that label is made especially for your automatic transaxle. Damage caused by fluid other than DEXRON-III is not covered by your new vehicle warranty. After adding fluid, recheck the fluid level as described under “How to Check.”

0 When the correct fluid level is obtained, push.the

dipstick back in all‘ the way.

How to Reset Transaxle Fluid Change Indicator Your vehicle is equipped with a transaxle fluid change indicator. A CHANGE TRANS FLUID message will display on the Driver Information Center (DIC) when the powertrain computer determines that the transaxle fluid needs to be changed. See your Maintenance Schedule booklet for more information. When this message appears, change the transaxle fluid and reset the transaxle fluid life indicator as follows: 1. Turn the ignition on but do not start the engine. 2. Press and hold the OFF and rear defog buttons on the

climate control at the same time until the TRANS FLUID RESET message appears on the DIC.

6-19

Engine Coolant The cooling system in your vehicle is filled with new DEX-COOL rm (orange-colored, silicate-free) engine coolant. This coolant is designed to remain in your vehicle for 5 years or 100,000 miles (1 66 000 km), whichever occurs first. The following explains your cooling system and how to add coolant when it is low. If you have a problem with engine overheating, see “Engine Overheating” in the Index. A 50/50 mixture of water and the proper coolant for your Cadillac will: 0 Give freezing protection aown to -34°F (-37°C). 0 Give boiling protection up to 265 “F (129 O C). 0 Protect against rust and corrosion. 0 Help keep the proper engine temperature. 0 Let the warning lights and gages work as they should.

6-20

NOTICE:

When adding coolant it is important that you use DEX-COOL (orange-colored, silicate-free) coolant meeting GM Specification 6277M. If dicated coolant is added to the system, premature engine, heater core or radiator corrosion may result. In addition, the engine

coolant will require change sooner -- at

30,000 miles (50 000 km) or 24 months, whichever occurs first.

What to Use Use a mixture of one-half clean water (preferably distilled) and one-half DEX-COOL (orange-colored, silicate-free) antifreeze that meets GM Specification 6277M, which won’t damage aluminum parts. Use GM Engine Coolant Supplement (sealer) (GM Part No. 3634621) with any complete coolant change. If you use this mixture, you don’t need to add anything else. A special procedure is required for adding sealer; see the Cadillac service manual. (To order a service manual, see “Service and Owner Publications” in the Index.)

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 DEX-COOL (orange-colored, silicate-free) antifreeze.

NOTICE:

If you use an improper coolant mix, your. engine could overheat and be badly damaged. The repair cost wouldn’t be covered by your warranty. Too much water in the mix can freeze and crack the engine, radiator, heater core and other parts.

If you have to add coolant more than four times a year, have your dealer check your cooling system.

NOTICE:

If you use the proper coolant, you don’t have to add extra inhibitors or additives which claim to improve the system. These can be harmful.

6-21

Checking Coolant

A CAUTION:

Tbrning the surge tank pressure cap when the engine and radiator are hot can allow steam and scalding liquids to blow out and burn you badly. Never turn the surge tank pressure cap -- even a little -- when the engine and radiator are hot.

,/'

When your engine is cold, the coolant level should be at the full cold mark, which is 2.5 inches (60 mm) below the base of the fill neck. Use a flashlight as necessary to see into the tank.

The surge tank is located next to the engine block on the passenger's side of the engine. The cooling system when hot is under a.lot of pressure. If the CHECK COOLANT LEVEL message appears on the DIC, you will need to add coolant.

6-22

Y

Adding Coolant If you need more coolant, add the proper mix at the surge tank, but only when the engine is cool.

I 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.

c1

When replacing the pressure cap, make sure it is tight.

Surge Tank Pressure Cap

I NOTICE:

.-

The surge tank cap is a 15 psi (105 kPa) ’ pressure-type cap and must be tightly installed to prevent coolant loss and possible engine damage from overheating. Be sure the arrows on the cap line up.

If the surge tank pressure cap needs to be replaced, a General Motors 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. If your thermostat needs to be replaced, a General Motors thermostat is recommended.

6-23

Power Steering Fluid

The power steering fluid reservoir is located next to the coolant surge tank on the passenger’s side of

When to Check 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.

6-24

How To Check Power Steering Fluid When the engine compartment is cool, 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. The level should be at the FULL COLD mark. If necessary, add only enough fluid to bring the level up to the mark. What to Use Refer to the Maintenance Schedule to determine what kind of fluid to use. See “Recommended Fluids and Lubricants” in the Maintenance Schedule booklet. Always use the proper fluid. Failure to use the proper fluid can cause leaks and damage hoses and seals. Windshield Washer Fluid What to Use When you need windshield washer fluid, be sure to read the manufacturer’s instructions before use. If you will be operating your vehicle in an area where the temperature may fall below freezing, use a fluid that has sufficient protection against freezing.

Adding Washer Fluid

The windshield washer fluid reservoir is located next to the air filter on the driver’s side of the engine. Open the cap labeled WASHER FLUID ONLY. Add washer fluid until the tank is full.

--

NOTICE:

.0

When using concentrated washer fluid, follow the manufacturer’s instructions 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 damage the tank if it is completely full. Don’t use radiator antifreeze in your windshield washer. It can damage your washer system and paint.

6-25

Brakes Brake Fluid

Your brake master cylinder reservoir is here. It is filled with DOT-3 brake fluid. There are only two reasons why the brake fluid level in the reservoir 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 6-26

--

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.

I A CAUTION:

If you have too much brake fluid, it can spill on is hot the engine. The fluid will burn if the engine enough. You or others could be burned, and your vehicle could be damaged. Add brake fluid only when work is done on the brake hydraulic system.

When your brake fluid falls to a low level, your brake warning light will come on. See “Brake System Warning Light” in the Index.

What to Add When you do need brake fluid, use only DOT-3 brake fluid -- such as Delco Supreme 11 No. 1052535). Use new brake fluid from a sealed container only, and always clean the brake fluid reservoir cap before removing it.

I A CAUTION:

With the wrong kind of fluid in your brake system, your brakes may not work well, or they may not even work at all. This could cause a crash. Always use the proper brake fluid.

NOTICE:

0 Using the wrong fluid can badly damage brake

system parts. For example, just a few drops of mineral-based oil, such as engine oil, in your brake system can damage brake system parts so badly that they’ll have to be replaced. Don’t let someone put in the wrong kind of fluid.

0 If you spill brake fluid on your vehicle’s painted

surfaces, the paint finish can be damaged. Be careful not to spill brake fluid on your vehicle. If you do, wash it off immediately. See “Appearance Care” in the Index.

Brake Wear Your Cadillac has four-wheel disc brakes. Disc brake pads have built-in wear indicators that make a high-pitched warning sound when the brake pads are worn and new pads are needed. The sound may come and go or be heard all the time your vehicle is moving (except when you are pushing on the brake pedal firmly).

1 A CAUTION:

The brake wear warning sound means that sooner or later your brakes won’t work well. That could lead to an accident. When you hear the brake wear warning sound, have your vehicle serviced.

I NOTICE:

Continuing to drive with worn-out brake pads could result in costly brake repair.
