Performance Traction Management is unavailable. The Active Handling System will feel different in aiding and maintaining directional control.

Competitive Driving Mode Competitive Driving Mode, Performance Traction Management, and Launch Control are systems designed to allow increased

performance while accelerating and/ or cornering. This is accomplished by regulating and optimizing the engine, brakes, and suspension performance. These modes are for use at a closed course race track and are not intended for use on public roads. They will not compensate for driver inexperience or lack of familiarity with the race track. Drivers who prefer to allow the system to have more control of the engine, brake, and suspension are advised to turn the normal traction control and active handling systems on. See Racing or Other Competitive Driving on page 9‑6. Notice: Do not attempt to shift when the drive wheels are spinning and do not have traction. This may cause damage to the transmission. Damage caused by misuse of the vehicle is not covered by the vehicle warranty. See the warranty book for additional information.

Driving and Operating

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). Cruise control will not work if the parking brake is set, or if the master cylinder brake fluid level is low.

{ WARNING

Cruise control can be dangerous where you cannot drive safely at a steady speed. So, do not use the 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 the vehicle is in cruise control, and has the Traction Control System (TCS), and it begins to limit wheel spin, the cruise control automatically disengages. See Traction Control System (TCS) on page 9‑34. When road conditions allow the cruise control to be safely used again, it can be turned back on.

The vehicle has cruise control. 9 (Off): Turns the system off. R (On): Turns the system on. + (Resume/Accelerate): Makes the vehicle accelerate or resume a previously set speed. T (Set): Press this button at the end of the lever to set the speed.

Setting Cruise Control If the cruise button is on when not in use, it could get bumped and go into cruise when not desired. Keep the cruise control switch off when cruise is not being used. 1. Move the cruise control switch

to on.

2. Get up to the speed desired. 3. Press T at the end of the lever

and release it.

4. Take your foot off the accelerator

pedal.

When the cruise control is engaged, the CRUISE SET TO XXX MPH message displays on the Driver Information Center (DIC). See Cruise Control Messages on page 5‑37.

Resuming a Set Speed If the cruise control is set at a desired speed and then the brakes are applied, the cruise control is disengaged without erasing the set speed from memory.

. Move the cruise switch from R to

+. Hold it there until desired speed is reached, and then release the switch. To increase the vehicle speed in small amounts, move the switch briefly to +. Each time this is done, the vehicle goes about 1.6 km/h (1 mph) faster.

Reducing Speed While Using Cruise Control If the cruise control system is already activated, . Press and hold the set button

until the lower speed desired is reached, then release it. To slow down in small amounts, briefly press J. Each time this is done, the vehicle goes about 1.6 km/h (1 mph) slower.

Driving and Operating

9-43

Passing Another Vehicle While Using Cruise Control Use the accelerator pedal to increase the vehicle speed. When you take your foot off the pedal, the vehicle will slow down to the previous set cruise speed.

Using Cruise Control on Hills How well the cruise control works on hills depends upon the vehicle speed, load, and the steepness of the hills. When going up steep hills, you might want to step on the accelerator pedal to maintain the vehicle speed. When going downhill, you might have to brake or shift to a lower gear to keep the vehicle's speed down. When the brakes are applied the cruise control is disengaged.

Once the vehicle speed reaches about 40 km/h (25 mph) or more, move the cruise control switch briefly from R to +. The vehicle returns to the previous set speed and stays there. If the switch is held at resume/ accelerate, the vehicle keeps going faster until the switch is released or the brake is applied. Do not hold the switch at resume/accelerate, unless you want the vehicle to go faster.

Increasing Speed While Using Cruise Control If the cruise control system is already activated, . Use the accelerator pedal to get to the higher speed. Press J at the end of the lever, then release the button and the accelerator pedal. If the accelerator pedal is held longer than 60 seconds, cruise control will turn off.

Driving and Operating

Cruise Control in Sport and Manual Paddle Shift Gear Selection When the vehicle is in S (Sport) and the manual paddle shift controls are not being used, cruise control operates in the same manner as D (Drive). When the vehicle is in S (Sport) and the manual paddle shift controls are being used, cruise control operates as follows:

If cruise control is active and a gear is selected with the manual paddle shift controls, the vehicle speed is maintained in the driver selected gear and will not automatically up-shift or down-shift the transmission while the driver’s gear selection is active.

If driving in hilly terrain, cruise control may not be able to maintain vehicle speed if an up-shift or down-shift is not selected by the driver. While driving on hilly terrain and cruise control is active with a manual paddle shift gear selection, the driver must select the proper gear for the terrain or select D (Drive) on the gear range selector for full automatic transmission operation.

Ending Cruise Control

To disengage cruise control, step lightly on the brake pedal. If the vehicle has a manual transmission, lightly tap the clutch to end the cruise control session. To turn off the cruise control system, move the cruise control switch to 9.

When cruise control is disengaged, the CRUISE DISENGAGED message displays on the Driver Information Center (DIC). See Cruise Control Messages on page 5‑37.

Erasing Speed Memory The cruise control set speed is erased from memory by moving the switch to 9 or if the ignition is turned off.

Fuel Use of the recommended fuel is an important part of the proper maintenance of this vehicle. To help keep the engine clean and maintain optimum vehicle performance, we recommend the use of gasoline advertised as TOP TIER Detergent Gasoline. Look for the TOP TIER label on the fuel pump to ensure gasoline meets enhanced detergency standards developed by auto companies. A list of marketers providing TOP TIER Detergent Gasoline can be found at www.toptiergas.com. TOP TIER gasoline is only available in the U.S. and Canada.

gasoline rated at 87 octane or higher, but the vehicle's acceleration could be slightly reduced, and a slight audible knocking noise, commonly referred to as spark knock, might be heard. If the octane is less than 87, a heavy knocking noise might be heard when driving. If this occurs, use a gasoline rated at 87 octane or higher as soon as possible. Otherwise, you could damage the engine. If heavy knocking is heard when using gasoline rated at 87 octane or higher, the engine needs service. If the vehicle has the 6.2L V8 engine (VIN Code T) or the 7.0L V8 engine (VIN Code E), use premium unleaded gasoline with a posted octane rating of 91 or higher. For best performance, use premium unleaded gasoline with a posted octane rating of 93. In an emergency, you can use regular unleaded gasoline with an octane rating of 87 or higher. If 87 octane fuel is used, do not perform any aggressive driving maneuvers such

The eighth digit of the Vehicle Identification Number (VIN) shows the code letter or number that identifies the vehicle's engine. The VIN is at the top left of the instrument panel. See Vehicle Identification Number (VIN) on page 12‑1.

Recommended Fuel If the vehicle has the 6.2L V8 engine (VIN Code W), use premium unleaded gasoline with a posted octane rating of 91 or higher. You can also use regular unleaded

Chevrolet Corvette Owner Manual - 2013 - crc2 - 11/8/12

Driving and Operating

as wide open throttle applications. You might also hear audible spark knock during acceleration. Refill the tank with premium fuel as soon as possible to avoid damaging the engine. If heavy knocking is heard when using gasoline rated at 91 octane or higher, the engine needs service.

Gasoline Specifications At a minimum, gasoline should meet ASTM specification D 4814. Some gasolines contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT). We recommend against the use of gasolines containing MMT. See Fuel Additives on page 9‑46.

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 vehicle might fail a smog‐check test. See Malfunction Indicator Lamp on page 5‑18. 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 might 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, 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 provide cleaner air, all gasolines in the United States are now required to contain additives that help prevent engine and fuel system deposits from forming, allowing the emission control system to work properly. In most cases, nothing should have to be added to the fuel. However, some gasolines contain only the minimum amount of additive required to meet U.S. Environmental Protection Agency regulations. To help keep fuel injectors and intake valves clean and avoid problems due to dirty injectors or valves, look for gasoline that is advertised as TOP TIER Detergent Gasoline. Look for the TOP TIER label on the fuel pump to ensure gasoline meets enhanced detergency standards developed by the auto companies. A list of

Chevrolet Corvette Owner Manual - 2013 - crc2 - 11/8/12

marketers providing TOP TIER Detergent Gasoline can be found at www.toptiergas.com. For customers who do not use TOP TIER Detergent Gasoline regularly, one bottle of Fuel System Treatment PLUS, part number 88861013, added to the fuel tank at every engine oil change, can help clean deposits from fuel injectors and intake valves. GM Fuel System Treatment PLUS is the only gasoline additive recommended by General Motors. It is available at your dealer. Gasolines containing oxygenates, such as ethers and ethanol, and reformulated gasolines might be available in your area. We recommend that you use these gasolines, if they comply with the specifications described earlier. However, E85 (85% ethanol) and other fuels containing more than 15% ethanol must not be used in vehicles that were not designed for those fuels.

Notice: This vehicle was not designed for fuel that contains methanol. 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. Some gasolines that are not reformulated for low emissions can contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT); ask the attendant where you buy gasoline whether the fuel contains MMT. We recommend against the use of such gasolines. Fuels containing MMT can reduce spark plug life and affect emission control system performance. The malfunction indicator lamp might turn on. If this occurs, return to your dealer for service.

Checking Engine Oil (Except Z06, ZR1, manual transmission Grand Sport Coupe, and 427
Convertible) If the CHECK OIL LEVEL message displays on the Driver Information Center (DIC), check the engine oil level right away. For more information, see Engine Oil Messages on page 5‑39. Check the engine oil level regularly; this is an added reminder. 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 on page 10‑8 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 allow several minutes for the oil to drain back into the oil pan. Checking the oil level too soon after engine shutoff will not provide an accurate oil level reading.

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

When to Add Engine Oil (Except Z06, ZR1, manual transmission Grand Sport Coupe, and 427 Convertible)

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 on page 12‑2. See Racing or Other Competitive Driving on page 9‑6 for additional information on engine oil.

Chevrolet Corvette Owner Manual - 2013 - crc2 - 11/8/12

Black plate (15,1)

Notice: 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 on page 10‑8 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.

See Engine Compartment Overview on page 10‑8 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 when checking the engine oil level. 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

Vehicle Care

tank and there could be no engine oil at all showing on the dipstick. This is normal since the dipstick is designed to read 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. Wait at least five minutes (but not more than 20 minutes) to allow oil to drain and settle in the engine.

{ WARNING

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

4. Remove the dipstick from the

external engine oil tank and clean it with a lint-free paper towel or a cloth. Re-insert the dipstick into the external oil tank, pushing it all the way in until it stops.

5. Remove the dipstick from the oil

tank and read the level on the cross-hatched area. Oil levels that fall in the cross-hatched area are normal.

When to Add Engine Oil (Z06, ZR1, manual transmission Grand Sport Coupe, and 427

If the oil is below the cross-hatched area at the tip of the dipstick, add 1 L (1 qt) of the recommended oil through the oil fill cap opening in the oil tank and then recheck the level. See “Selecting the Right Engine Oil” for an explanation of what kind of oil to use. For engine oil crankcase capacity, see Capacities and Specifications on page 12‑2.

3. Re-install both drain plugs and

tighten them to 25 Y (18 lb ft). 4. Replace the oil filter and tighten

it to 30 Y (22 lb ft). See Maintenance Replacement Parts on page 11‑14 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 9.9 L (10.5 quarts) of oil to the oil tank. See Capacities and Specifications on page 12‑2. Install the oil fill cap and insert the dipstick, if removed.

7.

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.

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 on page 11‑12.

Specification Use and ask for licensed engine oils with the dexos1® approved certification mark. Engine oils meeting the requirements for the vehicle should have the dexos1
approved certification mark. This certification mark indicates that the oil has been approved to the dexos1
specification. Corvette recommends Mobil 1® engine oils that meet the requirements of the dexos1
specification for its dry-sump equipped engines.

Notice: Failure to use the recommended engine oil or equivalent can result in engine damage not covered by the vehicle warranty. Check with your dealer or service provider on whether the oil is approved to the dexos1 specification.

Viscosity Grade SAE 5W-30 is the best viscosity grade for the vehicle. Do not use other viscosity grade oils such as SAE 10W-30, 10W-40, or 20W-50. 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

Chevrolet Corvette Owner Manual - 2013 - crc2 - 11/8/12

Black plate (19,1)

of the appropriate viscosity grade, always select an oil of the correct specification. See “Specification” earlier in this section for more information. Engine Oil Additives/Engine Oil Flushes Do not add anything to the oil. The recommended oils with the dexos specification and displaying the dexos certification mark 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.

Vehicle Care

10-19

Z06, ZR1, manual transmission Grand Sport Coupe, and 427
Convertible 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 on page 10‑13. When the system has calculated that oil life has been diminished, it indicates that an oil change is necessary. A CHANGE ENGINE OIL 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 might indicate that an oil change is not 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

Chevrolet Corvette Owner Manual - 2013 - crc2 - 11/8/12

important to check the oil regularly over the course of an oil drain interval and keep it at the proper level. 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. 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. Press the TRIP button so the

OIL LIFE percentage is displayed.
