Limited-Slip Differential (Except Z51 and Z06) If equipped, the mechanical limited-slip differential can give more traction on snow, mud, ice, sand, or gravel. It works like a standard axle most of the time, but when traction is low, this feature allows the drive wheel with the most traction to move the vehicle. For vehicles with limited slip differential, driven under severe conditions, the rear axle fluid should be changed. See Competitive Driving Mode 0 198 and Maintenance Schedule 0 298.

Driving and Operating

Limited-Slip Differential (Z51 and Z06 Only) If equipped, the Electronic Limited-Slip Differential (ELSD) is automatically activated. ELSD actively monitors vehicle sensors and driver inputs to determine the amount of change for the conditions. With ELSD, the vehicle has: . Enhanced high-speed control.

Improved traction through corners, allowing more acceleration.

. More precise steering.

Increased vehicle agility. Integration with StabiliTrak. For vehicles with ELSD, driven under severe conditions, the rear axle fluid should be changed. See Competitive Driving Mode 0 198
and Maintenance Schedule 0 298.

Cruise Control With cruise control, a speed of about 40 km/h (25 mph) or more can be maintained without keeping your foot on the accelerator. Cruise control does not work at speeds below about 40 km/h (25 mph).

{ Warning

Cruise control can be dangerous where you cannot drive safely at a steady speed. Do not use cruise control on winding roads or in heavy traffic. Cruise control can be dangerous on slippery roads. On such roads, fast changes in tire traction can cause excessive wheel slip, and you could lose control. Do not use cruise control on slippery roads.

If equipped with a manual transmission, the cruise control will remain active when the gears are shifted. The cruise is disengaged if the clutch is pressed for several seconds.

If the Traction Control System (TCS) begins to limit wheel spin while you are using cruise control, the cruise control automatically disengages. See Traction Control/Electronic Stability Control 0 192. When road conditions allow for using safely again, cruise control can be turned back on. If the brakes are applied, cruise control disengages.

Fuel Use of the recommended fuel is an important part of the proper maintenance of this vehicle. When driving in the U.S. and Canada, to help keep the engine clean and maintain optimum vehicle performance, we recommend TOP TIER Detergent Gasolines. See www.toptiergas.com for a list of TOP TIER Detergent Gasolines.

If equipped with the LT1 engine, use premium unleaded gasoline meeting ASTM specification D4814 with a posted octane rating of 91 or higher. Regular unleaded gasoline rated at

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico- 9085364) - 2016 - crc - 9/15/15

87 octane or higher can be used, but acceleration and fuel economy will be reduced, and an audible knocking noise may be heard. If this occurs, use a gasoline rated at 91 octane or higher as soon as possible. Otherwise, the engine could be damaged. If heavy knocking is heard when using gasoline with a 91 octane rating or higher, the engine needs service. If equipped with the LT4
supercharged engine, use premium unleaded gasoline meeting ASTM specification D4814 with a posted octane rating of 91 or higher. If the octane is less than 91, damage to the engine may occur and may void the vehicle warranty. If heavy knocking is heard when using gasoline rated at 91 octane or higher, the engine needs service.

Use of Seasonal Fuels Use summer and winter fuels in the appropriate season. The fuels industry automatically modifies the fuel for the appropriate season. If fuel is left in the vehicle tank for long periods of time, driving or

starting could be affected. Drive the vehicle until the fuel is at one-half tank or less, then refuel with the current seasonal fuel.

Prohibited Fuels Gasolines containing oxygenates such as ethers and ethanol, as well as reformulated gasolines, are available in some cities. If these gasolines comply with the previously described specification, then they are acceptable to use. However, E85 (85% ethanol) and other fuels containing more than 15% ethanol must be used only in FlexFuel vehicles.

Caution

Do not use fuel containing methanol. It can corrode metal parts in the fuel system and also damage plastic and rubber parts. That damage would not be covered under the vehicle warranty.

Driving and Operating

207

Some gasolines, mainly high octane racing gasolines, can contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT). Do not use gasolines and/or fuel additives with MMT as they can reduce spark plug life and affect emission control system performance. The malfunction indicator lamp may turn on. If this occurs, see your dealer for service.

California Fuel Requirements If the vehicle is certified to meet California Emissions Standards, it is designed to operate on fuels that meet California specifications. See the underhood emission control label. If this fuel is not available in states adopting California Emissions Standards, the vehicle will operate satisfactorily on fuels meeting federal specifications, but emission control system performance might be affected. The malfunction indicator lamp could turn on and the

Driving and Operating

vehicle may not pass a smog-check test. See Malfunction Indicator Lamp (Check Engine Light) 0 106. If this occurs, return to your authorized dealer for diagnosis. If it is determined that the condition is caused by the type of fuel used, repairs may not be covered by the vehicle warranty.

Fuels in Foreign Countries If planning to drive in countries outside the U.S. or Canada, the proper fuel might be hard to find. Check regional auto club or fuel retail brand websites for availability in the country where driving. Never use leaded gasoline, fuel containing methanol, manganese, or any other fuel not recommended. Costly repairs caused by use of improper fuel would not be covered by the vehicle warranty.

Fuel Additives To keep fuel systems clean, TOP TIER Detergent Gasoline is recommended. See Fuel 0 206. If TOP TIER Detergent Gasoline is not available, one bottle of Fuel System Treatment PLUS added to the fuel tank at every engine oil change, can help. Fuel System Treatment PLUS is the only gasoline additive recommended by General Motors. It is available at your dealer.

Engine Oil To ensure proper engine performance and long life, careful attention must be paid to engine oil. Following these simple, but important steps will help protect your investment: . Use engine oil approved to the proper specification and of the proper viscosity grade. See “Selecting the Right Engine Oil” in this section.

. Check the engine oil level regularly and maintain the proper oil level. See “Checking Engine Oil” and “When to Add Engine Oil” in this section.

. Change the engine oil at the

appropriate time. See Engine Oil Life System 0 228.

. Always dispose of engine oil

properly. See “What to Do with Used Oil” in this section.

Vehicle Care

223

Checking Engine Oil (Except Stingray with Z51 and Z06) If the ENGINE OIL LOW–ADD OIL message displays on the Driver Information Center (DIC), check the engine oil level right away. See Engine Oil Messages 0 123. Check the engine oil level regularly. It is a good idea to check the engine oil level at each fuel fill. In order to get an accurate reading, the vehicle must be on level ground. The engine oil dipstick handle is a loop. See Engine Compartment Overview 0 218 for the location of the engine oil dipstick. Obtaining an accurate oil level reading is essential: 1.

If the engine has been running recently, turn off the engine and check within five and 10 minutes of shutoff. Checking the oil level too soon after engine shutoff will not provide an accurate oil level reading.

Vehicle Care

{ Warning

The engine oil dipstick handle may be hot; it could burn you. Use a towel or glove to touch the dipstick handle.

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

When to Add Engine Oil (Except Stingray with Z51 and Z06)

If the oil is below the cross-hatched area at the tip of the dipstick, add 1 L (1 qt) of the recommended oil and then recheck the level. See “Selecting the Right Engine Oil” in

this section for an explanation of what kind of oil to use. For engine oil crankcase capacity, see Capacities and Specifications 0 312. See Track Events and Competitive Driving 0 162 for additional information on engine oil.

Caution

Do not add too much oil. Oil levels above or below the acceptable operating range shown on the dipstick are harmful to the engine. If you find that you have an oil level above the operating range, i.e., the engine has so much oil that the oil level gets above the cross-hatched area that shows the proper operating range, the engine could be damaged. You should drain out the excess oil or limit driving of the vehicle and seek a service professional to remove the excess amount of oil.

See Engine Compartment Overview 0 218 for the location of the engine oil fill cap. Add enough oil to put the level somewhere in the proper operating range. Push the dipstick all the way back in when through. Checking Engine Oil (Stingray with Z51 and Z06)

tank and there could be no engine oil at all showing on the dipstick. This is normal since the dipstick is designed to read the engine oil level only after the engine has run long enough to reach normal operating temperature. Do not add engine oil based on cold engine dipstick readings. The engine oil level on the dipstick will also be inaccurate if checked while the engine is running. 1. To obtain an accurate engine oil level reading, warm up the engine to at least 80 °C (175 °F). Cold oil will not give a correct oil level reading.

2. Once the engine is warm, turn off the engine. Checking the oil while the engine is running will result in an incorrect oil level reading.

3. Check the oil level between five and 10 minutes after the engine is shut down.

The engine oil dipstick handle is a loop. The dipstick is located on the dry sump engine oil tank. See Engine Compartment Overview 0 218 for the location of the dry sump engine oil tank. These vehicles have a racetrack-ready dry sump engine lubrication system. This high performance system operates differently than a standard engine lubrication system and requires a special procedure when checking the engine oil level. Follow this procedure closely. The engine oil level must be checked when the engine is warm. Cold oil level in the dry sump tank may not indicate the actual amount of oil in the system. With this system, engine oil is contained in an external tank, separate from the engine. Under normal operating conditions, the oil pan under the engine does not store any oil. If the vehicle has been parked for an extended period without the engine being started, some oil will seep back into the oil pan, reducing the amount of oil held in the dry sump

7.

Install the oil fill cap and insert the dipstick, if removed.

8. Start the engine and let it run at idle for at least 15 seconds. This will circulate the fresh engine oil through the lubrication system.

9. Shut off the engine and check

the oil level as described under “Checking Engine Oil (Z51 and Z06).”

Selecting the Right Engine Oil Selecting the right engine oil depends on both the proper oil specification and viscosity grade. See Recommended Fluids and Lubricants 0 307.

Specification Ask for and use engine oils that meet the dexos1™ specification.

Steps to follow: 1. Remove the two engine oil

drain plugs from the bottom of the engine oil pan. One drain plug drains the external oil tank via the oil transfer supply line. The other drain plug drains residual oil from the crankcase sump. Allow the oil to drain.

2. Once the oil has been drained

from the engine, remove the engine oil filter and allow the oil to drain.

3. Reinstall both drain plugs and

tighten them to 25 Y (18 lb ft).

4. Replace the oil filter and

tighten it three-quarters to one turn after gasket contact. See Maintenance Replacement Parts 0 309 for the correct filter. 5. Oil is filled through the opening

in the top of the external engine oil tank. Remove the oil fill cap.

6. Add oil to the oil tank. See

Capacities and Specifications 0 312.

Vehicle Care

227

Engine oils that have been approved by GM as meeting the dexos1 specification are marked with the dexos1 approved logo. See www.gmdexos.com. GM recommends Mobil 1® engine oils that show the dexos1 approved logo for its dry sump equipped engines.

Caution

Failure to use the recommended engine oil or equivalent can result in engine damage not covered by the vehicle warranty.

Viscosity Grade Use SAE 5W-30 viscosity grade engine oil. Cold Temperature Operation: In an area of extreme cold, where the temperature falls below −29 °C (−20 °F), an SAE 0W-30 oil may be used. An oil of this viscosity grade will provide easier cold starting for the engine at extremely low temperatures. When selecting an oil of the appropriate viscosity grade, it

Vehicle Care

is recommended to select an oil of the correct specification. See “Specification” earlier in this section. For track events or competitive driving, use Mobil 1® 15W-50 engine oil. An instrument cluster warning light will be illuminated at high oil temperatures. See Driver Information Center (DIC) 0 113. Engine Oil Additives/Engine Oil Flushes Do not add anything to the oil. The recommended oils meeting the dexos1™ specification are all that is needed for good performance and engine protection. Engine oil system flushes are not recommended and could cause engine damage not covered by the vehicle warranty. What to Do with Used Oil Used engine oil contains certain elements that can be unhealthy for your skin and could even cause cancer. Do not 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 dispose of 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 threat to the environment. If you change your own oil, be sure to drain all the oil from the filter before disposal. Never dispose of oil by putting it in the trash or pouring it on the ground, into sewers, or into streams or bodies of water. Recycle it by taking it to a place that collects used oil.

Engine Oil Life System

When to Change Engine Oil This vehicle has a computer that indicates when to change the engine oil and filter. This is based on a combination of factors which include engine revolutions, engine temperature, and miles driven. Based on driving conditions, the mileage at which an oil change is indicated can vary considerably. For the oil life system to work properly, the system must be reset every time the oil is changed.

Z51 and Z06 models have a racetrack-ready dry sump engine lubrication system. This high performance system operates differently than a standard engine lubrication system and requires a special procedure when changing the engine oil and filter. See Engine Oil 0 223. When the system has calculated that oil life has been diminished, it indicates that an oil change is necessary. A CHANGE ENGINE OIL SOON message comes on. Change the oil as soon as possible within the next 1 000 km (600 mi). It is possible that, if driving under the best conditions, the oil life system may not indicate that an oil change is necessary for up to a year. The engine oil and filter must be changed at least once a year and, at this time, the system must be reset. Your dealer has trained service people who will perform this work and reset the system. It is also important to check the oil regularly over the course of an oil drain interval and keep it at the proper level.

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico- 9085364) - 2016 - crc - 9/15/15

If the system is ever reset accidentally, the oil must be changed at 5 000 km (3,000 mi) since the last oil change. Remember to reset the oil life system whenever the oil is changed.

Dry Sump Engine Break-In Oil Change If equipped with a dry sump engine, the initial oil and filter change must be performed at 800 km/500 mi. Follow the engine oil life system for every oil change thereafter. How to Reset the Engine Oil Life System Reset the system whenever the engine oil is changed so that the system can calculate the next engine oil change. To reset the system: 1. Scroll through the DIC Info

Pages menu until the REMAINING OIL LIFE percentage is displayed. See Driver Information Center (DIC) 0 113.

2. Press and hold the SEL button

on the DIC while the Oil Life display is active. The oil life will change to 100%.

If the CHANGE ENGINE OIL SOON message comes back on when the vehicle is started, the engine oil life system has not reset. Repeat the procedure.

Automatic Transmission Fluid

How to Check Automatic Transmission Fluid It is not necessary to check the transmission fluid level. A transmission fluid leak is the only reason for fluid loss. If a leak occurs, take the vehicle to the dealer and have it repaired as soon as possible. The vehicle is not equipped with a transmission fluid level dipstick. There is a special procedure for checking and changing the transmission fluid. Because this procedure is difficult, this should be done at the dealer. Contact the

reason for fluid loss. If a leak occurs, take the vehicle to the dealer and have it repaired as soon as possible. See Recommended Fluids and Lubricants 0 307 for the proper fluid to use.

Hydraulic Clutch It is not necessary to regularly check clutch fluid unless you suspect there is a leak in the system. Adding fluid will not correct a leak. A fluid loss in this system could indicate a problem. Have the system inspected and repaired. The fluid will darken over time. See Maintenance Schedule 0 298 for when to replace the fluid. When to Check and What to Use

The hydraulic clutch fluid reservoir cap has this symbol on it. See Engine Compartment Overview 0 218 for reservoir location. Refer to Recommended Fluids and Lubricants 0 307 for the proper fluid to use. The fluid requires changing. See Maintenance Schedule 0 298. How to Check and Add Fluid Visually check the clutch fluid reservoir to make sure the fluid level is at the MIN (minimum) line on the side of the reservoir. The hydraulic clutch fluid system should be closed and sealed. Do not remove the cap to check the fluid level or to top off the fluid level. Remove the cap only when necessary to add the proper fluid until the level reaches the MIN line.
