Towing Your Corvette Try to have a GM dealer or a professional towing service tow your Corvette, The usual towing equipment is : (A) Sling-twe tow truck (B) Wheel-lift tow truck (C) Car carrier 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 cdI, tell the towing service:

That your vehicle cannot be towed -horn the rear with sling-type equipment. That your vehicle has rear-wheel drivei The make, model, and year of your vehicle.

Whether you can still movethe shift lever. If there was an accident, what was damaged.

If you get the overheat warning with no sign of steam, try this for a minute or so: 1 I Turn off your air conditioner. 2. Turn on your heater to €ull hot at the

highest fan speed and open the window as necessary.

3. Try to keep your engine under load

If the caulant inside the csolaht recovery tank is boiling, don’t do; anything else until it cuols dam.

rroblems on the Koad

How to Add Coolant to the Coolant Recovery Tank If you haven’t found a problem yet, but the coolant level isn’t at or above COLD, add a 50/50 mixture of clean water (preferably distilled) and a proper antifreeze at the coolant recovery tank. (See the Index under Coolant for more information about the proper coolant mix. )

If there seems to be no leak, 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.

.-

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

When the coolant in the coolant recovery tank is at or above COLD, start your vehicle. If the overheat warning continues, there's one more thing you can try. You can add the proper coolant mix directly to the coolant high fill reservoir, but be sure the cooling system is cool before you do it.

Gently brake to B stop, well off’ the road if posiible. If your tire go& flat, the next section shows how to use your jacking equipment to change a flat tire sdely.

lJu 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 yuur foot 08 the accelerator pedal and grip the steering wheel firmly. Steer to maintain lane p-osition, then gently brake to -a stop well out of the. traffic lam. A rear blowout, particularly on a curve, acts much like a skid and may require the same corre&ion you’d use in a skid.

Compact Spare Tire Although the compact spare was fully inflated when your vehicle was new, it can lase air after a time. Check the inflation pressure regularly. It should be 60 psi (420 1tPa). The compact spare is made to go up to 3,000 miles (5 OOO 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 .s.parewith .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.

Don't use your compact. spare on some other vehicle. And don't mix your compact spare or wheel with other wheels or tires. They won't fit. Keep your spare and its -wheel together.

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. The method known as “rocking” can I help you get out when you’re stuck, but

rou must use caution. CAUT/UN

A: If :you let.your :tires. spin -at

high speed.when the ASR , . ‘OFE warning light is on, or when “the SERVICE ASR warning light is ‘on, your tires can explode and you or others could be injured. And, spinning your tires with either of these lights on can cause the automatic transmission or other parts of the vehicle to 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 (56 M) as shown on the speedometer.

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 ASR system off. Then, shift back and forth between R (Reverse) and a forward gear--or if you have a manual transmission, between 1 or 2 and R (Reverse)-spinning little as possible. Release the accelerator pedal while you shift, and press lightly on the accelerator pedal when the transmission 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 the Index under Towing Your Corvette and Acceleration Slip Regulation (ASR) System.

Fael Use premium ,unleadedgasohe rated at 91 octane higher, You may use middle grade or rcgultir unleaded gasolines, but- your vehicle may not accelerate as well. The gasoline you use should meet specifications ASTM D4814 inthe US. and CGSB 3-5-92 in Canada. These fuels should have the proper additives, so you should not have to add- mything’to the fuel. In the US. and Canada, it’s easy to be sure. you get the right lrind of gasoline (unleaded). You’ll see “UNLEADED” right QII the pump. And-only unleaded nozzles will fit into your vehicle’s filler neck.

Be sure the posted-octane for premium is at least 91 (at leatit 89 €or middle- grade and 87 for regular). If the octane is less than 87, yuu may get a heavy knocking nu& when you drive. I€. it’s bad enough, it can damage YOLK engine. If you’re usingfuel rated at 91 octane or higher and you still hear heavy knocking, your engine needs service. But don’t w q 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. Fuel Capacity: 20 U. S. Gallons (75.7 L) . Use unleaded he1 only.

I Gasdines for Cleaner Air Your use of gasoline with detergent additives will help pr-event deposits from foxrning in your engine and fuel system. That helps keep your engine in tune and your emission control system workijng properly. 1t”s good for.your vehicle, md.,yoU’ll be doing-your part for cleaner- air. Many gasolines are now blended with materials called oxygenates, General Motors ree.omrnends’that-.you use ga.s.olines with these blending materials, suchas MTBEa~~.~~~af?crX.By.doing so, y . 0 ~ can help clean the air, especially in those parts. of thecountry that have high carbon monoxide levels.

In addition, some gasoline suppliers are now producing reformulated gasolines. These gasolinesare specially designed to reduce vehicle emissions. General Motors recommends that you use reformulated gasoline. By doing so, you can help clean the air, especially in those parts of the country that have high ozone levels. You should.aslc your service station operators if their gasolines contain detergents and oxygenates, and if they have been reformulated to reduce vehicle emissions.

Fuels in Foreign Countries If you plan on drivingh another country outside the U.S. or Canada, unleaded fuel may be hard to find. Do not use leaded gasoline. If you use even one tankful, your emission controls won't work well or at all. With continuous use, spa& plugs can get fouled, the exhaust system can corrode, and your engine oil can deteriorate quickly. Your vehicle's oxygen sensor will be damaged. All ofthat means costly repairs that wouldn't be covered by your warranty.

Engine Oil It's a good.idea to check p u r engine oil level every time you get fuel. In order to get an accurate reading, the vehicle must be on level ground. If you have the LTl engine, the best time to check your engine oil is when the engine is warn. If the engine is mnning, the engine oil won't drain back into the pan. 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.

If you have a ZR-1, the best time to chegk your engine oil is when the engine is cold. If you run the engine, the engine oil won't drain back into the pan fast enough. Give the oil two hours to drain back into the oil pan. If you don't, the oil dipstick might not show the actual level.

What to Do with Used, Oil

A Used engine- oil contains.

things that have caused skin .. ,cancer in laboratory animals. Don't let used oil stay.on your .skin for very long. Clean y o u skin and nails with soap and water, or a good hand cleaner. Wash or properly throw away ciuthing or rags containing used engine oil.

Air Cleaner Refer to the Maintenance Schedule to determine when to replace the air filter. ;ee the Index under Scheduled taintmame. Services. CAUTION

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 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 yo-ur used oil, ask your: dealer, a service station or a local recycling center €or help.

Brake Master Cylinder Your brake master cylinder is filled with DOT-3 brake fluid. There are only two reasons why the brake fluid level in your master cylinder might go down. The first is that the brake fluid goes down to an acceptable level during normal brake lining wear. When new linings are put in, the fluid level goes back up.

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

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 haye really good braking. Vehicles we design and test have top-quality GM brake-parts in the&, as your Corvette does when it is new. When you replace parts of your braking 'system-for example, when your brakelinings wear down and you sure have to have new ones put in-be you get new genuine GM replacement parts. If.you don't, your brakes may no longer work properly. For example, if someone.puts in b.r&e 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.
