1997 Oldsmobile Aurora Owners Manual

Backing Up Hold the bottom of the steenng 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 Turns

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. Turn Signals When Towing a Trailer 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.

Your vehicle may have bulb warning messages. When you plug a trailer lighting system into your vehicle’s lighting system, its bulb warning messages may not let you know if one of your lamps goes out. So, when you have a trailer lighting system plugged in, be sure to check your vehicle and trailer lamps from time to time to be sure they’re all working. Once you disconnect the trailer lamps, the bulb warning messages again can tell you if one of your vehicle lamps is out. 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. 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.

4-37

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.

But if you ever have to park your rig on a hill, here’s how to do it:

3. When the wheel chocks are in place, release the regular brakes until the chocks absorb the load.

4. Reapply the regular brakes. Then apply your parking

brake, and then shift to PARK (P).

5. 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: 0 Start your engine; 0 Shift into a gear; and 0 Release the parking brake.

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.

Hazard Warning Flashers

The HAZARD light on the instrument panel will also come on. Your hazard flashers work

HAZARD A no matter what position

your key is in, and even if the key isn't in.

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.

5-2

To turn off the flashers, press the button down again. When the flashers are on, your turn signals won't work.

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 Aurora. But please follow the steps below to do it safely.

NOTICE:

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

- fi CAUTION:

Batteries can hurt you. They can be dangerous because:

They contain acid that can burn you. 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.

1. Check the other vehicle. It must have a 12-volt

battery with a negative ground system.

I NOTICE:

If the other system isn’t a 12-volt system with a negative ground, both vehicles can be damaged.

5-3

..

2. 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 Aurora, and the bad grounding could damage the electrical systems. To avoid the possibility of the vehicles rolling, set the parking brake firmly on both vehicles involved in the jump start procedure. Put an automatic transaxle in PARK (P) before setting the parking brake. 3. Turn off the ignition on both vehicles. Unplug

unnecessary accessories plugged into the cigarette lighter or accessory power outlet. 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.

NOTICE:

If you leave your radio on, it could be badly damaged. The repairs wouldn’t be covered by your warranty.

5-4

4. Open the hoods and locate the other vehicle’s battery

and the Aurora’s remote positive (+) jump starting terminal in the box on the passenger side of the engine compartment. (Your Aurora’s battery isn’t under the hood.)

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

5. Find the positive (+) and negative (-) terminals on each battery or remote terminal. You should always use the remote positive (+) terminal instead of the positive (+) terminal on your battery. To open the remote positive (+) terminal box, pull the tab and open the cover.

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

missing insulation. If they do, you could get a shock. The vehicles could be damaged too. Before you connect the cables, here are some things you should how. 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.

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 f i e r 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.

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

5-5

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

positive (+) terminal of the vehicle with the dead battery.

8. Don’t let the other end touch metal. Connect it to the

positive (+) terminal of the good battery. Use a remote positive (+) terminal if the vehicle has one.

5-6

9. Now connect the black

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

Don’t let the other end 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.

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 a while.

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

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

5-7

13. Remove the cables in reverse order to prevent

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

Towing Your Vehicle Try to have an Oldsmobile retailer or a professional towing service tow your Aurora. 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 and illustrations 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 can only be towed from the front

with sling-type equipment.

0 That your vehicle has front-wheel drive. 0 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 detailed towing instructions and illustrations. The operator may want to see them.

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 T-hooks instead.

5-9

When your vehicle is being towed, have the ignition key turned to OFF. 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.

A vehicle can fall 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 T-hook slots. Never use J-hooks. They will damage drivetrain and suspension components.

5-10

Front Towing

NOTICE:

Do not tow with sling-type equipment or fascidfog lamp damage will occur. Use wheel-lift or car-carrier equipment. Additional ramping may be required for car-carrier equipment. Use safety chains and wheel straps. Towing a vehicle over rough surfaces could damage a vehicle. Damage can occur from vehicle to ground or vehicle to wheel-lift equipment. To help avoid damage, install a towing dolly and raise the vehicle until adequate clearance is obtained between the ground and/or wheel-lift equipment. to Do not attach winch cables or J-hooks suspension components when using car-carrier equipment. Always use T-hooks inserted in the T-hook slots.

5-11

These slots are to be used when loading and securing to car-carrier equipment.

Attach T-hook chains on both sides, in the slotted holes in the bottom of the body rail, behind the front wheels and cradle.

Attach a separate safety chain around the outboard end of each lower control arm.

NOTICE:

Be sure not to attach the safety chain to the drive axle. This could cause damage to the drive axle boot.

5-12

Rear Towing Tow Limits -- 35 mph (55 krdh), 25 miles (40 km)

Attach T-hook chains to the T-hook slots in the floor pan support rails just ahead of the rear wheels on both sides.

Position the lower-sling crossbar just ahead of the front edge of the rear bumper.

5-13

Attach a separate safety chain around the outboard end of each lower control arm.

Engine Overheating You will find a coolant temperature gage on your Aurora’s instrument panel. Your information center will also display messages about engine overheating. See “Coolant Temperature Gage” in the Index.

Overheated Engine Protection Operating Mode Should a low coolant condition exist and the message HOT STOP ENGINE is displayed, an overheat protection mode which alternates firing groups of four cylinders helps prevent engine damage. In this mode, you will notice a loss in power and engine performance. 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.

I 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 will be severely degraded. Repair the cause of coolant loss, change the oil and reset the oil life indicator. See “Engine Oil, When to Change” in the Index.

5-14

If Steam Is Coming From Your Engine

ontin d)

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 you open the hood. If you keep driving when your engine is overheated, the liquids in it can catch fire. You or others could be badly burned. Stop your engine if it overheats, and get out of the vehicle until the engine is cool.

I NOTICE:

you Steam from an overheated engine can burn badly, even if you just open the hood. Stay away from the engine if you see or hear steam coming CAUTION: (Continued)

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.

5-15

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:

Climb a long hill on a hot day. 0 Stop after high-speed driving. 0 Idle for long periods in traffic.

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. Turn on your heater to full hot at the highest fan

speed 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 -- AUTOMATIC OVERDRIVE (@) or THIRD (3).

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 0fSth.e 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 eet service help right away.

5-16

When you decide it’s safe to lift the hood, here’s what you’ll see:

I A CAUTION:

An electric fan under the hood can start up 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.

A. Coolant Surge Tank with Pressure Cap B. Two Electric Engine Cooling Fans

5-17

.

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.

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.

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

5-18

I

How to Add Coolant to the Coolant Surge Tank If you haven’t found a problem yet, but the coolant level isn’t at FULL COLD, add a 50/50 mixture of clean water (preferably distilled) and DEX-COOL@ coolant 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.)

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.

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@ coolant.

NOTICE:

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

~~

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.

5-20

1. You can remove the coolant surge tank pressure cap

2. Then keep turning the pressure cap slowly, and

when the cooling system,-including the coolant surge tank pressure cap and upper radiator hose, is no longer hot. Turn the pressure cap slowly about one-quarter turn to the left and then stop. If you hear a hiss, wait for that to stop. A hiss means there is still some pressure left.

remove it.

5-21

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

up to FULL COLD.

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 FULL COLD.

5-22

5. Then replace the pressure cap. Be sure the pressure

cap is tight.

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.

5-23

Ckanging 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.

............................................................................... ............................................................................... ............................................................................... .......................................... ...........................................

................. .................

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. Set the parking brake firmly. 2. Put the shift lever in PARK (P). 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.

5-24

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

Removing the Spare Tire and Tools

Instructions for changing your tires are on the inside of the tire cover. You can rest the cover near you for easy reference while you change the tire. Lift the tire cover to gain access to the spare tire and jacking equipment. Remove the wheel wrench and jack from the jack container. Remove the spare tire from the trunk.

The equipment you’ll need is in the trunk.

5-25

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

Insert the hooked end of the wheel wrench in one of the two small notches in the center cover and pry the cover off. Do not drop the cover or lay it face down, as it could be scratched or damaged. Do not use a hammer or mallet to install the cover when replacing the cover after the wheel is put back on the vehicle.

5-26

Removing the Flat Tire and Installing the Spare Tire

3. Turn the wheel wrench clockwise by hand to raise

the jack head a few inches.

1. Position the wheel wrench securely over the wheel

nuts to loosen, but don’t remove them.

2. Attach the wheel wrench to the bolt on the end of the

jack to create a jack handle.

5-27

1 17.5 INCHES I

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.

4. Near each wheel well is a notch in the frame to

position the jack head. You'll find the word JACK and an arrow stamped into the plastic near each notch. Position the jack under the vehicle and raise the jack head until it fits firmly against the sheet metal next to the word JACK. Do not raise the vehicle yet. Put the compact spare near you.

PL Cr' --------:

Raising your vehicle with the jack improperly positioned can damage the vehicle and even make the vehicle fall. To help avoid personal injury and vehicle damage, be sure to fit the jack lift head into the proper location before raising the vehicle.

7. Remove any rust or dirt

from the wheel bolts, mounting surfaces and spare wheel.

5. Raise the vehicle by rotating the wheel wrench

clockwise in the jack. Raise the vehicle far enough off the ground so there’s enough room for the spare tire to fit.

6. Remove all the wheel nuts and take off the flat tire.

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.

5-29

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

8. Place the spare tire on the wheel mounting surface.

~~

9. 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. If a nut cannot be tightened by hand, use the wrench, and see your retailer right away.

5-30

10. Lower the vehicle by rotating the wheel wrench

counterclockwise on the jack. Lower the jack completely.

11. Using the wheel

wrench, tighten the wheel nuts firmly in a crisscross sequence as shown.

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.

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 new GM original equipment wheel nuts. Stop somewhere as soon as you can and have the nuts tightened with a torque wrench to 100 Ib-ft (140 N-m).

12. Then replace the wheel cover. Be sure to position

the alignment pin on the cover with the notch in the wheel. Apply pressure around the edge of the cap to snap it in place. Don’t try to put the wheel cover on the compact spare tire. It won’t fit. Store the wheel cover in the trunk until you have replaced the compact spare tire with a regular tire.

I 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.

5-31

Storing the Flat Tire and Tools

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.

5-32

Store the flat tire as far forward in the trunk as possible. Store the jack and wheel wrench in their compartment in the trunk. For storage, the jack must be raised until the screw end is flush with the edge of the jack.

Storing the Spare Tire and Tools

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 collision, loose equipment could strike someone. Store all these in the proper place.

The compact spare tire is for temporary use only. Replace the compact spare tire with a full-size tire as soon as you can. See “Compact Spare Tire” later in this section. See the storage instructions label to replace your compact spare into your trunk properly.

SPARE TIRE COVER

5-33

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 Wa). 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 speeds up to 65 mph (105 km/h) 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.

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.

5-34

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 km/h) as shown on the speedometer.

I 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.

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. Be sure you have sufficient knowledge, experience, the proper replacement parts and tools before you attempt any vehicle maintenance task. 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.

Doing Your Own Service Work If you want to do some of your own service work, you’ll want to get the proper Aurora Service Manual. It tells you much more about how to service your Aurora than this manual can. To order the proper service manual, see “Service and Owner Publications” in the Index.

Adding Equipment to the Outside of Your Vehicle Things you might add to the outside of your vehicle can affect the airflow around it. This may cause wind noise and affect windshield washer performance. Check with your Aurora retailer before adding equipment to the outside of your vehicle. 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 specification could provide improved driveability and emission control system protection compared to other gasolines. Be sure the posted octane for premium is at least 9 1. the octane is less than 9 1, 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 hear heavy knocking, your engine needs service.

If

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 Aurora retailer 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. Some gasolines that are not reformulated for low emissions contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT); ask your service station operator whether or not his fuel contains MMT. General Motors does not recornend the use of such gasolines. If fuels containing MMT are used, spark plug life may be reduced and your emission control system performance may be affkcted. The malfunction indicator lamp on your instrument panel may turn on. If this occurs, return to your authorized Aurora retailer for service.

6-3

To provide cleaner air, all gasolines in the United States 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:

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.

Fuels in Foreign Cou ;ries If you plan on driving in another country outside the United States or Canada, the proper fuel may be 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).

Filling Your Tank

The cap is behind a hinged door on the left side of your vehicle. The remote fuel door release can help keep your fuel tank from being siphoned. Always be sure the fuel door is closed and latched after refueling.

To open the fuel door (on the left of the vehicle), press the button next to the trunk release button, to the right of the steering column. The ignition does not need to be on. The remote fuel door release will work in all transaxle positions.

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.

6-5

The fuel door can be opened manually in case of an electrical power failure. To do so, first open the trunk. The release mechanism is on the driver’s side of the vehicle, at the top of the trunk compartment. Pull the tab toward you to release the fuel door.

I NOTICE:

Prying on a locked fuel filler door could damage it. Use the remote fuel door manual release located in the trunk.

While refueling, hang the cap inside the fuel door. Twist it clockwise to secure it, if necessary. To take off the cap, turn it slowly to the left (counterclockwise).

6-6

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 Aurora” in the Index.

When you put the cap back on, turn it to the right (clockwise) until you hear a clicking sound. Make sure you fully install the cap. The diagnostic system can determine if the fuel cap has been left off or improperly installed. T h s would allow fuel to evaporate into the atmosphere. See “Malfunction Indicator Lamp” in the Index.

NOTICE:

If you need a new cap, be sure to get the right type. Your retailer 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.

To open the hood, first pull the hood release handle inside the vehicle, located to the left of the steering wheel under the instrument panel.

Hood Release

Checking Things Under the Hood k!, 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.

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.

The following sections tell you how to check fluids, lubricants and important parts underhood.

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.

Engine Oil

If the CHECK OIL LEVEL message or the oil warnkg light on the instrument panel comes on, it means you need to check your engine oil level right away.

7 3 OIL

For more information, see “Check Oil Level Message” or “Oil Pressure Warning Light” in the Index. You should check your engine oil level regularly; this is an added reminder. 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. 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.

6-11

When to Add Oil If the oil is at or below the ADD line, then you’ll need to add at least one quart of 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.

I 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.

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

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 (API). Do not use any oil which does not carry this Starburst symbol.

If 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 Easoline engines.

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

DO NOT USE SAE 2OW-50 OR ANY OTHER GRADE OIL NOT RECOMMENOED

As shown in the chart, SAE low-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 20W-50.

I NOTICE:

Use only engine oil with the American Petroleum Institute Certified For Gasoline Engines “Starburst” symbol. Failure to use the recommended oil can result in engine damage not covered by your warranty.

GM Goodwrench@ oil meets all the requirements for your vehicle. If you are in an area where the temperature falls below -20°F (-29”C), consider using either an SAE 5W-30 synthetic oil or an SAE OW-30 oil. Both will provide easier cold starting and better protection for your engine at extremely low temperatures.

6-13

Engine Oil Additives Don’t add anything to your oil. Your Aurora retailer is ready to advise if you think something should be added. When to Change Engine Oil If any one of these is true for you, use the short trip/city maintenance schedule:

Most trips are less than 5 to 10 miles (8 to 16 km). This is particularly important when outside temperatures are below freezing. Most trips include extensive idling (such as frequent driving in stop-and-go traffic). Most trips are through dusty areas. You frequently tow a trailer or use a carrier on top of your vehicle. The vehicle is used for delivery service, police, taxi or other commercial application.

Driving under these conditions causes engine oil to break down sooner. If any one of these is true for your vehicle, then you need to change your oil and filter every 3,000 miles (5 000 km) or 3 months -- whichever occurs first. (See “Change Oil Message’’ in the Index.) If the CHANGE OIL NOW message appears in the Driver Information Center, you should change your oil. If none of them is true, use the long triphighway maintenance schedule. Change the oil and filter every 7,500 miles ( 12 500 km) or 12 months -- whichever occurs first. Driving a vehicle with a fully warmed engine under highway conditions causes engine oil to break down slower. (See “Change Oil Message” in the Index.) Always reset the engine oil life to 100% after every oil change.

6-14

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 retailer, a service station or a local recycling center for help.

Air Cleaner To Check or Replace the Air Filter:

1. Remove hose from resonator channel.

6-15

2. Release tension of the wing screw clamp on the air intake duct where it attaches to the air cleaner cover near the top of the engine. Just turn the wing screw counterclockwise, then detach the duct from the air cleaner cover.

3. Push the duct and resonator assembly rearward and

up, and hold out of the way.

4. There’s a temperature sensor on the corner of the air

cleaner cover. Release the sensor’s electrical connector retainer, and pull up.

6-16

- , . .. .‘,. .

5. Unsnap the two clamps by pushing down on

the top of the air cleaner cover and pushing in on the clamps toward the center of the cover. Then remove the cover.

6. Remove the air filter. 7. Install the new air filter and reverse all steps to

reinstall the cover, electrical wires, duct and clamp. Be sure the tabs of the air cleaner cover fit into the slots of the air cleaner housing. Then make sure both clamps are fully engaged.

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

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: 0 In heavy city traffic where the outside temperature

regularly reaches 90 O F (32 O C ) or higher. In hilly or mountainous terrain.

0 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 Index.

Operating the engine with the air cleaner cause you or others to be burned. The air cleaner not only cleans the air, it stops flame 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.

if the engine

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.

6-18

How to Check Because this operation can be a little difficult, you may choose to have this done at your Aurora retail facility 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.

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.

Wait at least 30 minutes before checking the transaxle fluid level if you have been driving: 0 When outside temperatures are above 90 OF (32 O 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°F to 200°F (82°C to 93°C). Get the vehicle warmed up by driving about 15 miles (24 km) 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

Park your vehicle on a level place. keep the engine running. With the parking brake applied, place the shift lever in PARK (P). 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).

0 Let the engine run at idle for three to five minutes.

Then, without shutting off the engine, follow these steps:

1. 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.

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 in the acceptable range, 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 the Index. 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 one pint (0.5 L). Don’t overjill.

NOTICE:

We recommend you use only fluid labeled DEXRON’III, 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.

3. After adding fluid, recheck the fluid level as

described under “How to Check.”

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

dipstick back in all the way.

engine coolant. This coolant is designed

Engine Coolant The cooling s stem in your vehicle is filled with DEX-COOL to remain in your vehicle for 5 years or 150,000 miles (240 000 km), whichever occurs first, if you add only DEX-COOL@ extended life coolant. 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 DEX-COOL’ coolant will:

Give freezing protection down to -34°F (-37°C). Give boiling protection up to 265°F (129°C). Protect against rust and corrosion. Help keep the proper engine temperature, Let the warning lights and gages work as they should.

I NOTICE:

When adding coolant, it is important that you use only DEX-COOL@ (silicate-free) coolant. If coolant other than DEX-COOL@ 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. Damage caused by the use of coolant other than DEX-COOL@ is not covered by your new vehicle warranty.

What to Use Use a mixture of one-half clean water (preferably distilled) and one-half DEX-COOL@ coolant which won’t damage aluminum parts. If you use this mixture, you don’t need to add anything else. A special procedure is required for adding sealer; see the Aurora Service Manual. (To order a service manual, see “Service Publications’’ in the Index.)

r = 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@ coolant.

6-22

I 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 retailer check your cooling system.

I 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.

Checking Coolant

The engine coolant surge tank is located on the driver’s side of the engine compartment.

6-23

- ~.

A CAUTION:

When your engine is cold, the coolant level should be at the FULL COLD mark or a little higher.

'hrning 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.

6-24

If the message LOW ENGINE COOLANT is displayed on your message center, it means you’re low on engine coolant.

Adding Coolant If you need more coolant, add the proper DEX-COOL’ coolant mixture at the surge tank, but only when the engine is cool.

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.

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

6-25

Power Steering Fluid 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.

How To Check Power Steering Fluid When the engine compartment is cool, wipe the cap and the top of the reservoir clean, then 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.

6-26

Adding Washer Fluid

What to Use To determine what kind of fluid to use, see “Recommended Fluids and Lubricants” in the Index. 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.

There are two windshield washer fluid tanks. The upper tank (shown above) will empty first. When the lower tank contains 0.5 quarts (0.5 liters) or less, the message LOW WASHER FLUID will be displayed on the Driver Information Center.

6-27

Open the cap labeled WASHER FLUID ONLY. Add washer fluid until the tank is full.

Brakes Brake Fluid

NOTICE:

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 three-quarters full when it’s very cold. This allows for expansion if freezing occurs, 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.

6-28

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 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 ofi?’ 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.

When your brake fluid falls to a low level, your brake warning light will come on. A chime will sound if you try to drive with this warning light 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 1 I No. 12377967). Use new brake fluid from a sealed container only. Always clean the brake fluid reservoir cap and the area around the cap before removing it. This will help keep dirt from entering the reservoir.

(GM Part

If you have too much brake fluid, it can spill on the engine. The fluid will burn if the engine is hot 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.

With the wronb -4nd 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:

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. 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 Aurora 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 fiily).

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

NOTICE:

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

Some driving conditions or climates may cause a brake squeal when the brakes are first applied or lightly applied. This does not mean something is wrong with your brakes. Properly torqued wheel nuts are necessary to help prevent brake pulsation. When tires are rotated, inspect brake pads for wear and evenly torque wheel nuts in the proper sequence to GM specifications. Brake linings should always be replaced as complete axle sets. See “Brake System Inspection” in Section 7 of this manual under Part C “Periodic Maintenance Inspections.” Brake Pedal Travel See your retailer if the brake pedal does not return to normal height, or if there is a rapid increase in pedal travel. This could be a sign of brake trouble.

Brake Ad-iustment Every time you apply the brakes, with or without the vehicle moving, your brakes adjust for wear. 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. Your vehicle was designed and tested with top-quality GM brake parts. 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 approved 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 Aurora has a Delco Freedom@ battery. You never have to add water to one of these. When it’s time for a new battery, we recommend a Delco Freedom battery. Get one that has the replacement number shown on the original battery’s label. The battery is located under the rear seat cushion. To access the battery,’ see “Removing the Rear Seat Cushion” in the Index. You don’t need to access the battery to jump start your vehicle. See “Jump Starting” in the Index.

A battery that isn’t properly vented can let sulfuric acid fumes into the area under the rear seat cushion. These fumes can damage your rear seat safety belt systems. You may not be able to see this damage, and the safety belts might not provide the protection needed in a crash. If a replacement battery is ever needed, it must be vented in the same manner as the original battery. Always make sure that the vent hose is properly reattached before reinstalling the seat cushion. 6-32

To be sure the vent hose (A) is properly attached, the vent hose connectors (B) must be securely reattached to the vent outlets ( C ) on each side of the battery, and the vent assembly grommet (D) must be secured to the floor pan (E).

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

r ning down. A CAUTION:

Bulb Replacement For any bulb changing procedure not listed in this section, contact your Aurora retailer’s service department. For the type of bulb to use, see “Replacement Bulbs” in the Index. Halogen Bulbs

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 retailer to learn how to prepare your vehicle for longer storage periods. Also, for your audio system, see “Theft-Deterrent Feature” in the Index.

A CAUTION:

Halogen bulbs have pressurized gas inside and can burst if you drop or scratch the bulb. You or others could be injured. Be sure to read and follow the instructions on the bulb package.

Exterior Front Bulbs

Headlamp Aiming Your vehicle has the composite headlamp system. These headlamps have horizontal and vertical aim indicators. The aim has been pre-set at the factory and should need no further adjustment. If your vehicle is damaged in an accident and the headlamp aim seems to be affected, see your Aurora retailer. Headlamps on damaged vehicles may require recalibration of the horizontal aim by your Aurora retailer. To check the aim, the vehicle should be properly prepared as follows:

The vehicle must have all four tires on a perfectly level surface. The vehicle should not have any snow, ice or mud attached to it. There should not be any cargo or loading of the vehicle, except it should have a full tank of gas and one person or 160 lbs. (75 kg) on the driver’s seat. Tires should be properly inflated.

I NOTICE:

To make sure your headlamps are aimed properly, read all the instructions before beginning. Failure to follow these instructions could cause damage to headlamp parts.

State inspection stations will allow a vertical reading of plus 0.76 degrees or minus 0.76 degrees from the center of the bubble. It is recommended that the upper limit not exceed plus 0.4 degrees from the center of the bubble. Other drivers may flash their high beams at you if your adjustment is much above plus 0.4 degrees.

If you find that the headlamp aiming needs adjustment, follow these steps: Start with the vertical headlamp aim. Don't try to adjust the horizontal aim first. Adjustment screws can be turned with an E8 Torx@socket or T15 Torx screwdriver.

2. Now adjust the horizontal aim. Check the horizontal

aim for each headlamp and adjust it as necessary. Turn the horizontal aiming screw until the pointer is lined up with the 0 (zero).

3. Now, visually re-check the vertical aim, to make

sure it is still correct after the horizontal aim adjustment. Readjust, if necessary.

1. Check the vertical aim for each headlamp. The

vehicle must be on a level surface. Turn the vertical aiming screw until the bubble in the level is centered at 0 (zero).
