1997 Buick Regal Owners Manual

Winter Driving

Here are some tips for winter driving:

Have your vehicle in good shape for winter. You may want to put winter emergency supplies in your trunk.

Include an ice scraper, a small brush or broom, a supply of windshield washer fluid, a rag, some winter outer clothing, a small shovel, a flashlight, a red cloth and a couple of reflective warning triangles. And, if you will be driving under severe conditions, include a small bag of sand, a piece of old carpet or a couple of burlap bags to help provide traction. Be sure you properly secure these items in your vehicle.

Driving on Snow or Ice Most of the time, those places where your tires meet the road probably have good traction. However, if there is snow or ice between your tires and the road, you can have a very slippery situation. You’ll have a lot less traction or “grip” and will need to be very careful.

What’s the worst time for this? “Wet ice.” Very cold snow or ice can be slick and hard to drive on. But wet ice can be even more trouble because it may offer the least traction of all. You can get wet ice when it’s about freezing (32” F; 0°C) and freezing rain begins to fall. Try to avoid driving on wet ice until salt and sand crews can get there. Whatever the condition -- smooth ice, packed, blowing or loose snow -- drive with caution. Accelerate gently. Try not to break the fragile traction. If you accelerate too fast, the drive wheels will spin and polish the surface under the tires even more.

If You’re Caught in a Blizzard

Your anti-lock brakes improve your vehicle’s stability when you make a hard stop on a slippery road. Even though you have the anti-lock braking system, you’ll want to begin stopping sooner than you would on dry pavement. See “Anti-Lock’’ in the Index. 0 Allow greater following distance on any

slippery road. Watch for slippery spots. The road might be fine until you hit a spot that’s covered with ice. On an otherwise clear road, ice patches may appear in shaded areas where the sun can’t reach: around clumps of trees, behind buildings or under bridges. Sometimes the surface of a curve or an overpass ma remain icy when the surrounding roads are clear. If you see a-patch of ice ahead of you, brake before you are on it. Try not to brake while you’re actually on the ice, and avoid sudden steering maneuvers.

If you are stopped by heavy snow, you could be in a serious situation. You should probably stay with your vehicle unless you know for sure that you are near help and you can hike through the snow. Here are some things to do to summon help and keep yourself and your passengers safe: 0 Turn on your hazard flashers.

4-29

Tie a red cloth to your vehicle to alert police that you’ve been stopped by the snow. Put on extra clothing or wrap a blanket around you. If you have no blankets or extra clothing, make body insulators from newspapers, burlap bags, rags, floor mats -- anything you can wrap around yourself or tuck under your clothing to keep warm.

A CAUTION:

Snow can trap exhaust gases under your vehicle. This can cause deadly CO (carbon monoxide) gas to get inside. CO could overcome you and kill you. You can’t see it or smell it, so you might not know it is in your vehicle. Clear away snow from around the base of your vehicle, especially any that is blocking your exhaust pipe. And check around again from time to time to be sure snow doesn’t collect there. Open a window just a little on the side of the vehicle that’s away from the wind. This will help keep CO out.

You can run the engine to keep warm, but be careful.

4-30

Run your engine only as long as you must. This saves fuel. When you run the engine, make it go a little faster than just idle. That is, push the accelerator slightly. This uses less fuel for the heat that you get and it keeps the battery charged. You will need a well-charged battery to restart the vehicle, and possibly for signaling later on with your headlamps. Let the heater run for a while. Then, shut the engine off and close the window almost all the way to preserve the heat. Start the engine again and repeat this only when you feel really uncomfortable from the cold. But do it as little as possible. Preserve the fuel as long as you can. To help keep warm, you can get out of the vehicle and do some fairly vigorous exercises every half hour or so until help comes.

Two labels on your vehicle show how much weight it may properly carry. The Tire-Loading Information label is inside the trunk lid. The label tells you the proper size, speed rating and recommended inflation pressures for the tires on your vehicle. It also gives you important information about the number of people that can be in your vehicle and the total weight you can carry. This weight is called the vehicle capacity weight and includes the weight of all occupants, cargo and all nonfactory-installed options.

THIS VEHICLE CONFORMS TO ALL APPLI- CABLE U.S. FEDERAL MOTOR VEHICLE SAFETY, BUMPER, AND THEFT PREVENTION STANDARDS IN EFFECT ON THE DATE OF MANUFACTURE SHOWN ABOVE.

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

The other label is the Certification label, found on the rear edge of the driver’s door. It tells you the gross weight capacity of your vehicle, called the GVWR (Gross Vehicle Weight Rating). The GVWR includes the weight of the vehicle, all occupants, fuel and cargo. Never exceed the GVWR for your vehicle or the Gross Axle Weight Rating (GAWR) for either the front or rear axle. If you do have a heavy load, spread it out. Don’t carry more than 167 pounds (75 kg) in your trunk.

NOTICE:

Your warranty does not cover parts or components that fail because of overloading.

If you put things inside your vehicle -- like suitcases, tools, packages or anything else -- they will go as fast as the vehicle goes. If you have to stop or turn quickly, or if there is a crash, they’ll keep going.

need to.

Towing a Trailer

If you don’t use the correct equipment and drive properly, you can lose control when you pull a brakes may not work well -- or even at all. You trailer. For example, if the trailer is too heavy, the and your passengers could be seriously injured. Pull a trailer only if you have followed all the steps in this section. Ask your Buick dealer for advice and information about towing a trailer with your vehicle.

NOTICE:

Pulling a trailer improperly can damage your vehicle and result in costly repairs not covered by your warranty. To pull a trailer correctly, follow the advice in this part, and see your Buick dealer for important information about towing a trailer with your vehicle.

-.

4-33

Do not tow a trailer if your vehicle is equipped with the 3800 L67 Supercharged engine. Your vehicle can tow a trailer if it is equipped with the proper trailer towing equipment. To identify what the vehicle trailering capacity is for your vehicle, you should read the information in “Weight of the Trailer” that appears later in this section. But trailering is different than just driving your vehicle by itself. Trailering means changes in handling, durability and fuel economy. Successful, safe trailering takes correct equipment, and it has to be used properly. That’s the reason for this part. In it are many time-tested, important trailering tips and safety rules. Many of these are important for your safety and that of your passengers. So please read this section carefully before you pull a trailer. Load-pulling components such as the engine, transaxle, 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 km) 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 50 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.

4-34

Three important considerations have to do with weight:

In Canada, write to:

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). 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:

Buick Motor Division Customer Relations Center 902 E. Hamilton Avenue Flint, MI 48550

General Motors of Canada Limited Customer Communication Centre 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.

4-35

Total Weight on Your Vehicle’s Tires Be sure your vehicle’s tires are inflated to the upper limit for cold tires. You’ll find these numbers on the Tire-Loading Information label (found inside the trunk lid) 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 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. 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.

If you’re using a weight-carrying hitch, the trailer tongue (A) should weigh 10 percent of the total loaded trailer weight (B). If you have a weight-distributing hitch, the trailer tongue (A) should weigh 12 percent 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.

4-36

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, do not try to tap into your vehicle’s brake system. If you do, both brake systems won’t work well, or at all.

Driving with a Trailer Towing a trailer requires a certain amount 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.

4-37

wing Distance

3tay 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 mrns

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.

4-38

Turn Signals When Towing a Trailer When you tow a trailer, your vehicle may need a different turn signal flasher and/or extra wiring. Check with your Buick 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 k m h ) to reduce the possibility of engine and transaxle overheating.

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 don’t shift into

PARK (P) yet.

2. Have someone place chocks under the

trailer’s wheels.

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 shift to PARK (P).

5. Release the regular brakes.

4-39

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;

0 Shift into a gear; and

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.

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.

Jump Starting If your battery has run down, you may want to use another vehicle and some jumper cables to start your Buick. 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 Buick by pushing or pulling it won’t work, and it could damage your vehicle.

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.

NOTICE:

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

5-3

2.

3.

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 Buick, 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 your automatic transaxle in PARK (P) before setting the parking brake. 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!

I NOTICE:

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

4. Open the hoods and locate the batteries. (Your

vehicle’s battery is located under the windshield washer fluid reservoir.)

An electric fan 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.

5-4

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.

5. Find the positive (+) and negative (-) terminals on each battery. Your Buick has a remote positive (+) jump starting terminal. The terminal is on the same side of the engine compartment as your battery. To uncover the remote positive (+) terminal, squeeze the sides of the red plastic cap and pull the cap upward. You should always use the remote positive (+) terminal instead of the positive (+) terminal on your battery.

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 basic 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.

Try to start the vehicle with the dead battery. If it won’t start after a few tries, it probably needs service. Remove the cables in reverse order to prevent electrical shorting. Take care that they don’t touch each other or any other metal. Reinstall the red protective remote jump start cover on the vehicle that was jump started.

Towing Your Vehicle Try to have a Buick dealer or a professional towing service tow your vehicle. 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:

That your vehicle cannot be towed from the front or rear with sling-type equipment.

0 That your vehicle has front-wheel drive.

The make, model and year of your vehicle. Whether you can still move the shift lever. 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.

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.

When your vehicle is being towed, have the ignition key in 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.

5-10

Front Towing

NOTICE:

Do not tow with sling type equipment or fascia/fog 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. Use the T-slots for car-carrier securing. 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. Do not attach winch cables or J-hooks to suspension components when using car-carrier equipment. Always use T-hooks inserted in the T-hook slots.

5-11

Attach T-hook chains in front of the wheels, into the slots of the front shipping brackets on the cradle (both sides). Insert the hook from the inward side of the slot and not the outward side.

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

/A

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

Engine Overheating You will find a coolant temperature gage and a hot engine warning light on your instrument panel. See “Engine Coolant Temperature Gage” and “Engine Coolant Temperature Warning Light” in the Index. You also have a low coolant light on your instrument panel. See “Low Coolant Light” in the Index. If Steam Is Coming From Your Engine

Steam 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 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.

1 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.

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. 0 Stop after high-speed driving. 0 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. 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 (@).

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 o f t h e engine and get everyone out of the vehicle until it cools down. You may decide not to lift the hood but to get service help right away.

5-16

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

h!~ 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 recovery tank is boiling, don’t do anything else until it cools down.

A. Coolant Recovery Tank B. Electric Engine Fans C. Radiator Pressure Cap

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.

The coolant level should be at or above the COLD mark on the overflow hose in the coolant bottle. 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.

Engine damage from running your engine without coolant isn’t covered by your warranty.

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.

isn’t at the COLD mark, add a 50/50 mixture of clean water (preferably distilled) and DEX-COOL@ (silicate-free) antifreeze at the coolant recovery tank. (See “Engine Coolant” in the Index for more information.) /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.

5-19

If the overheat warning continues, there’s one more thing you can try. You can add the proper coolant mix directly to the radiator, but be sure the cooling system is cool before you do it.

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 radiator pressure cap -- even a little -- they can come out at high speed. Never turn the cap when the cooling system, including the radiator pressure cap, is hot. Wait for the cooling system and radiator pressure cap to cool if you ever have to turn the pressure cap.

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

When the coolant in the coolant recovery tank is at the COLD mark, start your vehicle.

5-20

1. You can remove the radiator pressure cap when the cooling system, including the radiator 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.

How to Add Coolant to the Radiator

I NOTICE:

Your engine has a specific radiator fill procedure. Failure to follow this procedure could cause your engine to overheat and be severely damaged.

2. Then keep turning the pressure cap, but now push down as you turn it. Remove the pressure cap.

l... . .

..

3. After the engine cools,

open the coolant air bleed valve.

There is one bleed valve. It is located on the thermostat housing.

' /$\ 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

4. Fill the radiator with the

proper DEX-COOL@ coolant mixture, up to the base of the filler neck.

If you see a stream of coolant coming from an air bleed valve, close the valve. Otherwise, close the valve(s) after the radiator is filled.

5. Rinse or wipe any spilled coolant from the engine

and the compartment.

6. Then fill the coolant recovery tank to the COLD mark on the overflow hose in the coolant bottle. 7. Put the cap back on the coolant recovery tank, but

leave the radiator pressure cap off.

5-23

8. Start the engine and let it run until you can feel the upper radiator hose getting hot. Watch out for the engine fans.

9. By this time, the coolant level inside the radiator filler neck may be lower. If the level is lower, add more of the proper DEX-COOL@ coolant mixture through the filler neck until the level reaches the base of the filler neck.

10. Then replace the pressure cap. At any time during this procedure if coolant begins to flow out of the filler neck, reinstall the pressure cap. Be sure the arrows on the pressure cap line up like this.

1 1. Check the coolant in the recovery tank. The level in

the coolant recovery tank should be at the HOT mark when the engine is hot or at the COLD mark when the engine is cold.

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.

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, of the you can put blocks at the front and rear tire farthest away from the one being changed. That would be the tire on the other side vehicle, at the opposite end.

Wheel Covers

To remove a center cap, use the wrench to pry gently at the notch. Don't use a tool that is narrower than the wrench to pry at this notch. Then pry off the cap.

":!

The tools you'll be using include the jack (A), extension and protection guide (B) and wheel wrench (C).

5-28

If your vehicle is equipped with wheel covers, be sure to use a wheel wrench to begin the process of loosening the plastic wheel nut caps.

Removing the Flat Tire and Installing the Spare Tire

They won’t come off. You will only be able to loosen them. Once you have loosened the plastic nut caps with the wheel wrench, if needed, you can finish loosening them with your fingers. Then, using the flat end of the wheel wrench, pry along the edge of the wheel cover until it comes off. Be careful; the edge may be sharp. Don’t try to remove the cover with your bare hands.

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

Don’t remove them yet.

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

head a few inches.

5-29

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.

3. For jacking at the vehicle’s front location, put the jack lift head about 6 inches (15 cm) from the rear edge of the front wheel opening or just behind the two bolts as shown.

5-30

A CAUTION:

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.

4. Raise the vehicle by turning the jack handle to the

right. 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.

5-31

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.

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. ,

6. Remove any rust or dirt

from the wheel bolts, mounting surfaces and spare wheel.

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.

5-32

9. Tighten the wheel nuts firmly in a crisscross sequence as shown.

8. Lower the vehicle by turning the jack handle to the

left. Lower the jack completely.

-

I NOTICE:

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 lb-ft (140 Nom).

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 the 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

Stc ng 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. When storing a full-size tire you must use the extension with the protector/guide to help avoid wheel surface damage. Use the extension and protector/guide located in the foam holder. To store a full-size tire, place the tire valve stem facing down and then remove the protector/guide and attach the retainer securely.

When reinstalling a compact spare tire, put the protector/guide back in the foam holder. Store the cover as far forward as possible.

Storing the Spare 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.

The compact spare is for temporary use only. Replace the compact siare tire with afull-size tire as soon as you can. See “Compact Spare Tire” in the Index. See the storage instructions label to replace your compact spare into your tntnk properly. Be sure to calibrate your low tire pressure system after you replace your compact spare tire with a full-sized one. See “Tire Pressure Monitor” in the Index.

5-36

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 speeds up to 65 mph (105 kmh) 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.

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.

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.

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. If your vehicle has the Enhanced Traction System, you should turn the system off. (See “Enhanced Traction System” in the Index.) If your vehicle has the Traction Control System, you should turn the 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 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 Index.

I A CAUl ON:

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.

Service Your Buick dealer knows your vehicle best and wants you to be happy with it. We hope you’ll go to your dealer for all your service needs. You’ll get genuine GM parts and GM-trained and supported service people. We hope you’ll want to keep your GM vehicle all GM. Genuine GM parts have one of these marks:

Doing Your Own Service Work If you want to do some of your own service work, you’ll want to use the proper Buick Service Manual. It tells you much more about how to service your Buick 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 Buick” in the Index.

6-2

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 Buick dealer before adding equipment to the outside of your vehicle. Fuel The 8th digit of your vehicle identification number (VIN) shows the code letter for your engine. You will find the VIN at the top left of your instrument panel. (See “Vehicle Identification Number” in the Index.) If you have the 3800 engine (VIN Code K), use regular unleaded gasoline rated at 87 octane or higher. If you’re using fuel rated at the recommended octane or higher and you hear heavy knocking, your engine needs service. But don’t worry if you hear a little pinging noise when you’re accelerating or driving up a hill. That’s normal, and you don’t have to buy a higher octane fuel to get rid of pinging. It’s the heavy, constant knock that means you have a problem.

If you have the 3800 Supercharged engine (VIN Code l), use premium unleaded gasoline rated at 91 octane or higher. With the 3800 Supercharged engine, in an emergency, you may be able to use a lower octane -- as low as 87 -- if heavy knocking does not occur. If you are using 91 or higher octane unleaded gasoline and you hear heavy knocking, your engine needs service. At a minimum, the gasoline you use should meet specifications ASTM D48 I4 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 91 (at least 89 for middle grade and 87 for regular). If the octane is less than 87, you may get a heavy knocking noise when you drive. If it’s bad enough, it can damage your engine.

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.

I 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.

If your vehicle is certified to meet California Emission Standards (indicated on the underhood emission control 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 Buick 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. 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 recommend 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 affected. The malfunction indicator lamp on your instrument panel may turn on. If this occurs, return to your authorized Buick dealer for service.

6-4

Fuels in Foreign Countries If you plan on driving in another country ourside 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

A CA

ION:

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.

The tethered cap is behind a hinged door on the left side of your vehicle.

6-5

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 Buick” in the Index.

While refueling, let the cap hang by the tether below the fuel fill opening. To take off the cap, turn it slowly to the left (counterclockwise). The cap has a spring in it; if you let go of the cap too soon, it will spring back to the right.

6-6

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. This 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 dealer can get one for you. If you get the wrong type, it may not fit properly. This may cause your malfunction indicator lamp to light and your fuel tank and emissions system may be damaged. See “Malfunction Indicator Lamp” in the Index.

Checking Things Under the Yood

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.

Hood Release

To open the hood, first pull the handle inside the vehicle, located just below the instrument panel and to the left of the steering column.

E Engine Oil Fill Cap G. Automatic Transaxle Fluid Dipstick H. Brake Fluid Reservoir I. Engine Coolant Recovery Tank J. Air Cleaner

Before closing the hood, be sure all the filler caps are on properly. Then just pull the hood down and close it firmly. 3800 Supercharged (Code 1) Engine (If Equipped) Your Buick may have a 3800 Supercharged engine. The supercharger is a device which is designed to pump more air into the engine than it would normally use. This air is mixed with fuel, which creates increased engine power. Since the supercharger is a pump and is driven from an engine accessory drive belt, increased pressure is available at all driving conditions. The powertrain control module (PCM), works with a vacuum control to regulate the increased pressure required during specific driving conditions. When this increased pressure or boost is not desired, such idling and light throttle cruising, the excess air that the supercharger is pumping is routed through a bypass. All of these controls working together provide high performance character and fuel efficiency 3800 Supercharged L67 engine.

LOW OIL

If the LOW OIL light on the instrument panel comes on, it means you need to check your engine oil level right away. For more information, see “Low Oil Level 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.

6-11

Checking Engine Qil Pull out the dipstiik and clean it with a paper tuwel or cloth, then push it back iri all the way. Remove it again, keeping the tip down, ;and check the level.

The engine oil dipstick handle is the yellow loop near the front of the engine. Turn off the engine and give the oil a drain back into the oil pan. If you don’t, the oil dipstick might not show the actual level.

few minutes to

6-12

When to Add Oil If the oil is at or below the ADD mark, 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.

NOTICE:

Don’t add too much oil. If your engine has so much oil that the oil level gets above the cross-hatched area 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 Tnstitute certified for gasoline engines.

The engine oil fill cap is located toward the front of the engine near the yellow-looped engine oil dipstick handle.

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

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 O F ( 14 O 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.

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.

Engine Oil Additives Don’t add anything to your oil. Your Buick dealer 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 tripkity 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 Soon” Light in the Index.)

If none of them is true, use the long trip/highway 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 Soon” Light 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

To check or replace the air filter, loosen the wing nut on the air duct and lift up on the two clips located on the top of the filter cover, Disconnect the duct and reposition it while removing the side cover.

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 flame 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.

Passenger Compartment Air Filter

The passenger compartment air filter is located underneath your hood just below the windshield wiper arm on the car’s passenger side (underneath the air inlet grill.) The filter traps most of the pollen from the air entering the vehicle. Like your vehicle’s air filter, it may need to be changed periodically. For information on how often to change the passenger compartment air filter, see “Maintenance Schedule” in the Index.

To change the passenger compartment air filter, use the following steps:

Supercharger Oil Unless you are technically qualified and have the proper tools, you should let your dealer or a qualified service center perform this maintenance. When to Check Check oil level every 30,000 miles (50 000 km) or every 36 months, whichever occurs first. What Kind of Oil to Use See “Recommended Fluids and Lubricants’’ in the Index and use only the recommended oil.

How to Check and Add Oil Check oil only when the engine is cold. Allow the engine to cool two to three hours after running.

If you remove the supercharger oil fill plug while the engine is hot, pressure may cause hot oil to blow out of the oil fill hole. You may be burned. Do not remove the plug until the engine cools.

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. In hilly or mountainous terrain. When doing frequent trailer towing. 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.

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

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). 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 0 Park your vehicle on a level place. Keep the

engine running.
