Driving and Operating

The vehicle can be safely shifted into R (Reverse) while the vehicle is moving less than 5 km/h (3 mph). If the vehicle is going faster than that, R (Reverse) is locked out. Shift Speeds Use the following shift speeds, shown in km/h (mph), for the best fuel economy.

1 to 4
4 to 5
5 to 6
6 to 7

27 (17) 40 (25) 64 (40) 72 (45)

{ Caution

When shifting gears, do not move the shift lever around unnecessarily. This may damage the transmission. Shift directly into the next gear.

1–4 Shift Message When the DIC displays this message, the vehicle can only be shifted from 1 (First) to 4 (Fourth). See Transmission Messages on page 5-44. Downshifting Do not downshift into the gear at a speed greater than shown:

1 (First)

released, the engine, clutch, driveshaft or transmission could be damaged.

If the engine speed drops below 900 rpm, or if the engine is not running smoothly, downshift to the next lower gear. It may be necessary to downshift two or more gears. The transmission has a spring that centers the shift lever near 3 (Third) and 4 (Fourth). This spring helps to know what gear the shift lever is in when shifting. Be careful when shifting from 1 (First) to 2 (Second) or downshifting from 7 (Seventh) to 6 (Sixth). The spring will try to pull the shift lever toward 4 (Fourth) and 3 (Third). Move the lever into 2 (Second) or 6 (Sixth) and do not let the shift lever move in the direction of the pulling, or it could shift from 1 (First) to 4 (Fourth) or from 7 (Seventh) to 4 (Fourth).

If the vehicle is not upshifted as the engine speed approaches fuel shut off rpm, the engine speed will be limited to protect the engine. See Tachometer on page 5-12.

Active Rev Match Vehicles equipped with a manual transmission have Active Rev Match (ARM). ARM aids in smoother shifting by matching the engine speed to the next selected gear. By monitoring shift lever and clutch operation, ARM adjusts engine speed to match a calibrated value based on gear selection. On upshifts and downshifts, engine speed will be increased and decreased to match vehicle road speed and transmission gear position. ARM is maintained for a few seconds between shifts, then deactivates if the shift is not completed.

The system is activated and deactivated by pressing either of the paddles marked REV MATCH on the steering wheel. The system must be activated with each new ignition cycle.

A gear indicator in the instrument cluster displays the current gear selected: . When ARM is activated, the

gear number is amber.

. When ARM is deactivated, the

gear number is white.

. A white dash indicates that

service is required. ARM will be disabled, and the malfunction indicator lamp will be on. See Malfunction Indicator Lamp on page 5-18. The clutch and manual transmission will continue to operate normally.

ARM will also: . Be active above 32 km/h

(20 mph).

. Match engine speed up to

5400 rpm.

. Not operate when the

accelerator pedal is applied.

. Be disabled when the coolant

temperature is below 0°C (32°F).

Driving and Operating

Brakes

Antilock Brake System (ABS) This vehicle has ABS, an advanced electronic braking system that helps prevent a braking skid. When the vehicle begins to drive away, ABS checks itself. A momentary motor or clicking noise might be heard while this test is going on, and it might even be noticed that the brake pedal moves a little. This is normal.

If there is a problem with ABS, this warning light stays on. See Antilock Brake System (ABS) Warning Light on page 5-22.

If driving safely on a wet road and it becomes necessary to slam on the brakes and continue braking to avoid a sudden obstacle, a computer senses the wheels are slowing down. If one of the wheels is about to stop rolling, the computer will separately work the brakes at each wheel. ABS can change the brake pressure to each wheel, as required, faster than any driver could. This can help you steer around the obstacle while braking hard. As the brakes are applied, the computer keeps receiving updates on wheel speed and controls braking pressure accordingly. Remember: ABS does not change the time needed to get a foot up to the brake pedal or always decrease stopping distance. If you get too close to the vehicle in front of you, there will not be enough time to apply the brakes if that vehicle

suddenly slows or stops. Always leave enough room up ahead to stop, even with ABS. Using ABS Do not pump the brakes. Just hold the brake pedal down firmly and let ABS work. You may hear the ABS pump or motor operating and feel the brake pedal pulsate. This is normal. Braking in Emergencies ABS allows you to steer and brake at the same time. In many emergencies, steering can help more than even the very best braking.

Electric Parking Brake

The vehicle has an Electric Parking Brake (EPB). The switch is on the center console. The EPB can always be activated, even if the ignition is off. To prevent draining the battery, avoid repeated cycles of the EPB when the engine is not running.

Driving and Operating

9-35

The system has a red parking brake status light and an amber parking brake warning light. See Electric Parking Brake Light on page 5-21
and Service Electric Parking Brake Light on page 5-21. There are also parking brake-related Driver Information Center (DIC) messages. See Brake System Messages on page 5-34. In case of insufficient electrical power, the EPB cannot be applied or released. Before leaving the vehicle, check the red parking brake status light to ensure that the parking brake is applied. EPB Apply To apply the EPB: 1. Be sure the vehicle is at a

complete stop.

2. Lift up the EPB switch

momentarily.

The red parking brake status light will flash and then stay on once the EPB is fully applied. If the red parking brake status light flashes

continuously, then the EPB is only partially applied or there is a problem with the EPB. A DIC message will display. Release the EPB and try to apply it again. If the light does not come on, or keeps flashing, have the vehicle serviced. Do not drive the vehicle if the red parking brake status light is flashing. See your dealer. See Electric Parking Brake Light on page 5-21. If the amber parking brake warning light is on, lift up on the EPB switch and hold it up. Continue to hold the switch until the red parking brake status light remains on. If the amber parking brake warning light remains on, see your dealer. If the EPB is applied while the vehicle is moving, the vehicle will decelerate as long as the switch is held up. If the switch is held up until the vehicle comes to a stop, the EPB will remain applied. The vehicle may automatically apply the EPB in some situations when the vehicle is not moving. This is

Driving and Operating

normal, and is done to periodically check the correct operation of the EPB system. If the EPB fails to apply, the rear wheels should be blocked to prevent vehicle movement. EPB Release To release the EPB: 1. Place the ignition in the ACC/

ACCESSORY or ON/RUN position.

2. Apply and hold the brake pedal. 3. Push down momentarily on the

EPB switch.

The EPB is released when the red parking brake status light is off. If the amber parking brake warning light is on, release the EPB by pushing down on the EPB switch and holding it down. Continue to hold the switch until the red parking brake status light is off. If either light stays on after release is attempted, see your dealer.

{ Caution

Driving with the parking brake on can overheat the brake system and cause premature wear or damage to brake system parts. Make sure that the parking brake is fully released and the brake warning light is off before driving.

Automatic EPB Release The EPB will automatically release if the vehicle is running, placed into gear, and an attempt is made to drive away. Avoid rapid acceleration when the EPB is applied, to preserve parking brake lining life. The EPB can also be used to prevent roll back for vehicles with a manual transmission taking off on a hill. When no roll back is desired, an applied EPB will allow both feet to be used for the clutch and accelerator pedals in preparation for starting the vehicle moving in the

intended direction. In this case, there is no need to push the switch to release the EPB.

Brake Assist The Brake Assist feature is designed to assist the driver in stopping or decreasing vehicle speed in emergency driving conditions. This feature uses the stability system hydraulic brake control module to supplement the power brake system under conditions where the driver has quickly and forcefully applied the brake pedal in an attempt to quickly stop or slow down the vehicle. The stability system hydraulic brake control module increases brake pressure at each corner of the vehicle until the ABS activates. Minor brake pedal pulsation or pedal movement during this time is normal and the driver should continue to apply the brake pedal as the driving situation dictates. The Brake Assist feature will automatically disengage when the

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico- 7576293) - 2015 - crc - 6/17/14

brake pedal is released or brake pedal pressure is quickly decreased.

Hill Start Assist (HSA) If equipped, HSA may automatically activate when the vehicle is stopped on a grade. This feature is designed to prevent the vehicle from rolling, either forward or rearward, during vehicle drive off. During the transition from releasing the brake pedal to accelerating to drive off on a grade, HSA holds the braking pressure to prevent rolling. HSA will not activate if the vehicle is in a drive gear and facing downhill or if the vehicle is facing uphill and in R (Reverse).

Driving and Operating

Ride Control Systems

Traction Control/ Electronic Stability Control The vehicle has a Traction Control System (TCS) and a StabiliTrak system. These systems help limit wheel spin and assist the driver in maintaining control, especially on slippery road conditions. TCS activates if it senses that the rear wheels are spinning too much or are beginning to lose traction. When this happens, TCS applies the brakes to the spinning wheel and reduces engine power (by closing the throttle and managing engine spark) to limit wheel spin. StabiliTrak activates when the vehicle senses a difference between the intended path and the direction the vehicle is actually traveling. StabiliTrak selectively applies braking pressure to any one of the

vehicle wheel brakes to assist the driver in keeping the vehicle on the intended path. If cruise control is being used when TCS begins to limit wheel spin, the cruise control will automatically disengage. Cruise control may be reengaged when road conditions allow. See Cruise Control on page 9-48. Both systems come on automatically when the vehicle is started and begins to move. The systems may be heard or felt while they are operating or while performing diagnostic checks. This is normal and does not mean there is a problem with the vehicle. It is recommended to leave both systems on for normal driving conditions, but it may be necessary to turn TCS off if the vehicle gets stuck in sand, mud, ice, or snow. See If the Vehicle Is Stuck on page 9-13 and “Turning the Systems Off and On” later in this section.

Driving and Operating

The indicator light for both systems is in the instrument cluster. This light will:

Flash when TCS is limiting wheel spin. Flash when StabiliTrak is activated. Turn on and stay on when either system is not working.

If either system fails to turn on or to activate, a message displays in the Driver Information Center (DIC), and d comes on and stays on to indicate that the system is inactive and is not assisting the driver in maintaining control. The vehicle is safe to drive, but driving should be adjusted accordingly.

If d comes on and stays on: 1. Stop the vehicle. 2. Turn the engine off and wait

15 seconds.

3. Start the engine. Drive the vehicle. If d comes on and stays on, the vehicle may need more time to diagnose the problem. If the condition persists, see your dealer. Turning the Systems Off and On

Launch Control (Track Mode Only) A Launch Control feature is available, within Competitive Driving Mode (except Z51 and Z06 with Magnetic Ride Control) or Performance Traction Management (Z51 and Z06 with Magnetic Ride

Control), on all vehicles to allow the driver to achieve high levels of vehicle acceleration in a straight line. Launch Control is a form of traction control that manages tire spin while launching the vehicle. This feature is intended for use during closed course race events where consistent zero to 60 and quarter mile times are desirable. Launch Control is only available when the following criteria are met: . Competitive Driving Mode is

selected (except Z51 and Z06
with Magnetic Ride Control) or any of the Performance Traction Management modes are selected (Z51 and Z06 with Magnetic Ride Control). The TCS light comes on the instrument panel and the appropriate DIC message displays. The vehicle is not moving. The steering wheel is pointing straight.

Manual Transmissions

The clutch is pressed and the vehicle is in 1 (First) gear. The accelerator pedal is rapidly applied to wide open throttle. The Launch Control feature will initially limit engine speed as the driver rapidly applies the accelerator pedal to wide open throttle. Allow the engine rpm to stabilize. A smooth, quick release of the clutch, while maintaining the fully pressed accelerator pedal, will manage wheel slip. Complete shifts as described in Manual Transmission on page 9-31.

Automatic Transmissions

The brake pedal must be firmly pressed to the floor, equivalent to a panic brake event. The accelerator pedal is rapidly applied to wide open throttle. (If the vehicle rolls due to wide open throttle, release the throttle, press the brake pedal

more firmly, and re-apply the accelerator to wide open throttle.)

The Launch Control feature will initially limit engine speed as the driver rapidly applies the accelerator pedal to wide open throttle. Allow the engine rpm to stabilize. A smooth, quick release of the brake pedal, while maintaining the fully pressed accelerator pedal, will manage wheel slip. After the vehicle is launched, the system continues in Competitive Driving Mode (except Z51 and Z06
with Magnetic Ride Control) or Performance Traction Management (Z51 and Z06 with Magnetic Ride Control). Competitive Driving Mode, PTM, and Launch Control are systems designed for a closed course race track and not intended for use on public roads. The systems are not intended to compensate for lack of driver experience or familiarity with the race track.

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 on page 9-43 and Maintenance Schedule on page 11-2.

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 limited slip differential, driven under severe conditions, the rear axle fluid should be changed. See Competitive Driving Mode on page 9-43 and Maintenance Schedule on page 11-2.

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).

{ 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 on page 9-37. When road conditions allow for using safely again, cruise control can be turned back on. If the brakes are applied, cruise control disengages.

Driving and Operating

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 have to step on the accelerator pedal to maintain your speed. When going downhill, you might have to brake or shift to a lower gear to keep your speed down. If the brake pedal is applied, cruise control will disengage.

Cruise Control in Manual Paddle Shift Gear Selection When the vehicle is in M (Manual Mode) 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 M (Manual Mode) 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 upshift or downshift 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 upshift or downshift 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 . Step lightly on the brake pedal.

If equipped with a manual transmission, press the clutch pedal for several seconds or shift to Neutral to disengage cruise control.

posted octane rating of 91 or higher. Regular unleaded gasoline rated at 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.

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

Driving and Operating

{ 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.

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 vehicle may not pass 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 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 on page 9-53. 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
