Driving and Operating

Control of a Vehicle Braking, steering, and accelerating are important factors in helping to control a vehicle while driving.

Braking Braking action involves perception time and reaction time. Deciding to push the brake pedal is perception time. Actually doing it is reaction time. Average driver reaction time is about three-quarters of a second. In that time, a vehicle moving at 100 km/h (60 mph) travels 20 m (66 ft), which could be a lot of distance in an emergency.

Helpful braking tips to keep in mind include: . Keep enough distance between

you and the vehicle in front of you.

. Avoid needless heavy braking. . Keep pace with traffic. If the engine ever stops while the vehicle is being driven, brake normally but do not pump the brakes. Doing so could make the pedal harder to push down. If the engine stops, there will be some power brake assist but it will be used when the brake is applied. Once the power assist is used up, it can take longer to stop and the brake pedal will be harder to push.

Steering

Magnetic Effort Steering This system continuously adjusts the effort felt when steering at all vehicle speeds. It provides ease when parking, yet a firm, solid feel at highway speeds. Hydraulic Power Steering Your vehicle has hydraulic power steering. It may require maintenance. See Power Steering Fluid Power Steering Fluid on page 10‑32. If power steering assist is lost because the engine stops or the power steering system is not functioning, the vehicle can be steered but may required increased effort. See your dealer if there is a problem.

Curve Tips

Off-Road Recovery

Take curves at a reasonable speed.

. Reduce speed before entering

a curve.

. Maintain a reasonable steady

speed through the curve

. Wait until the vehicle is out of the curve before accelerating gently into the straightaway.

Steering in Emergencies

There are some situations when steering around a problem may be more effective than braking.

. Holding both sides of the

steering wheel allows you to turn 180 degrees without removing a hand.

. Antilock Brake System (ABS) allows steering while braking.

The vehicle's right wheels can drop off the edge of a road onto the shoulder while driving. Follow these tips: 1. Ease off the accelerator and then, if there is nothing in the way, steer the vehicle so that it straddles the edge of the pavement.

Driving and Operating

2. Turn the steering wheel about one-eighth of a turn, until the right front tire contacts the pavement edge.

3. Then turn the steering wheel to go straight down the roadway.

Loss of Control

Skidding There are three types of skids that correspond to the vehicle's three control systems: . Braking Skid — wheels are

not rolling.

. Steering or Cornering

Skid — too much speed or steering in a curve causes tires to slip and lose cornering force. . Acceleration Skid — too much

throttle causes the driving wheels to spin.

Chevrolet Corvette Owner Manual - 2012

Black plate (6,1)

9-6

Driving and Operating

Defensive drivers avoid most skids by taking reasonable care suited to existing conditions, and by not overdriving those conditions. But skids are always possible. If the vehicle starts to slide, follow these suggestions: . Ease your foot off the

accelerator pedal and quickly steer the way you want the vehicle to go. The vehicle may straighten out. Be ready for a second skid if it occurs.

. Slow down and adjust your driving according to weather conditions. Stopping distance can be longer and vehicle control can be affected when traction is reduced by water, snow, ice, gravel, or other material on the road. Learn to recognize warning clues — such as enough water, ice, or packed snow on the road to make a mirrored surface — and slow down when you have any doubt.

Try to avoid sudden steering, acceleration, or braking, including reducing vehicle speed by shifting to a lower gear. Any sudden changes could cause the tires to slide.

Remember: Antilock brakes help avoid only the braking skid.

Racing or Other Competitive Driving Racing or competitive driving may affect the vehicle warranty. See the warranty book before using the vehicle for racing or other competitive driving. Notice: If you use the vehicle for racing or other competitive driving, the engine may use more oil than it would with normal use. Low oil levels can damage the engine. For information on how to add oil, see Engine Oil on page 10‑14.

Z06, ZR1, and Grand Sport Coupe manual transmission only: Be sure to check the oil level often during racing or other competitive driving and keep the level at or near the upper mark that shows the proper operating range on the engine oil dipstick. Except Z06, ZR1, and Grand Sport Coupe manual transmission: Be sure to check the oil level often during racing or other competitive driving and keep the level at or near 1 L (1 qt) above the upper mark that shows the proper operating range on the engine oil dipstick. After the competitive driving, remove excess oil so that the level on the dipstick is not above the upper mark that shows the proper operating range.

If the vehicle is a Z06, ZR1, or Grand Sport Coupe manual transmission model, it has greaseable outer ends on both of the rear toe‐links. Under normal use, lubrication should be performed as described in the maintenance schedule. See Maintenance Schedule on page 11‑3 and Recommended Fluids and Lubricants on page 11‑12. If using the vehicle for racing, lubrication should be performed at the end of each racing day. See your dealer for lubrication and make sure any needed repairs are made at once.

Proper procedures for performing these services can be found in the service manual. See Service Publications Ordering Information on page 13‑18. If the vehicle is used for racing or other competitive driving, the rear axle fluid temperatures may be higher than would occur in normal driving. We recommend that the rear axle fluid be drained and refilled with new fluid after every 24 hours of racing or competitive driving. See Recommended Fluids and Lubricants on page 11‑12 for what fluid to use.

Z06, ZR1, and Grand Sport Coupe manual transmission Only: For racing or competitive driving, it is recommended that the brake fluid be replaced with a high performance brake fluid that has a dry boiling point greater than 279°C (534°F). After conversion to the high performance brake fluid, follow the brake fluid service recommendations outlined by the fluid manufacturer. Do not use silicone or DOT‐5 brake fluids. Z06, ZR1, and Grand Sport Coupe manual transmission Only: For racing or competitive driving, it is recommended that the loading of the vehicle be limited to the driver only, with no other cargo, and that tires be inflated to 180 kPa (26 psi) for a maximum speed of 230 km/h (143 mph).

ZR1 and Z06 with Z07
Performance Package Brake Burnish Procedure Notice: These procedures are specific to the ZR1 and Z06
Performance Package with ceramic brake rotors. These procedures should not be run on other Corvette models as damage may result. Notice: The new vehicle break‐in period should be completed before performing the brake burnish procedure or damage may occur to the powertrain/ engine. See New Vehicle Break-In on page 9‑18. When performed as instructed, these procedures will not damage the brakes. During the burnishing procedure, the brake pads will smoke and produce an odor. The braking force and pedal travel may increase. After the procedure is complete, the brake pads may appear white at the rotor contact.

Street High Performance Brake Burnishing Procedure Run this procedure in a safe manner and in compliance with all local and state ordinances/laws regarding motor vehicle operation. Run this procedure only on dry pavement. 1. From a stop, accelerate as rapidly as possible without activating traction control to a speed of 97 kph (60 mph). 2. Use enough pedal force to

completely stop the vehicle in four to five seconds. If ABS activates, braking is too hard.

3. Repeat Steps 1 and 2,

five times. This should take about 10 minutes.

4. After completing the 50 stops, cool the brakes by driving for 8 km (5 mi) at 97 kph (60 mph). As with all high performance brake systems, some amount of brake squeal is normal.

Racing/Track Brake Burnish Procedure To prepare the ZR1 and Z06 with Z07 Performance Package brake system for track events and racing, the Street High Performance Brake Burnish as described previously should be completed. In addition to completing the Street High Performance Brake Burnishing Procedure, the following procedure needs to be completed to make the ZR1 and Z06 with Z07 Performance Package brake system ready for track events and racing. This procedure should only be run on a track and only on dry pavement.

Chevrolet Corvette Owner Manual - 2012

Black plate (9,1)

Notice: Brake pedal fade will occur during this track burnish procedure and can cause brake pedal travel and force to increase. This could extend stopping distance until the brakes are fully burnished. 1. Drive a normal first lap and not

too aggressive.

2. Laps 2 and 3 should be

gradually driven faster and more aggressive, while allowing for reduced brake output and increased stopping distance due to brake fade.

3. Lap 4 as near to full speed,

while allowing for reduced brake output and increased stopping distance due to brake fade. 4. Laps 5 and 6 should be cool

down laps

5. Lap 7 should be normal driving

or an easy out lap.

Driving on Wet Roads Rain and wet roads can reduce vehicle traction and affect your ability to stop and accelerate. Always drive slower in these types of driving conditions and avoid driving through large puddles and deep‐standing or flowing water.

{ WARNING

Wet brakes can cause crashes. They might not work as well in a quick stop and could cause pulling to one side. You could lose control of the vehicle. After driving through a large puddle of water or a car/vehicle wash, lightly apply the brake pedal until the brakes work normally.

Driving and Operating

9-9

WARNING (Continued)

Flowing or rushing water creates strong forces. Driving through flowing water could cause the vehicle to be carried away. If this happens, you and other vehicle occupants could drown. Do not ignore police warnings and be very cautious about trying to drive through flowing water.

Hydroplaning Hydroplaning is dangerous. Water can build up under the vehicle's tires so they actually ride on the water. This can happen if the road is wet enough and you are going fast enough. When the vehicle is hydroplaning, it has little or no contact with the road. There is no hard and fast rule about hydroplaning. The best advice is to slow down when the road is wet.

Driving and Operating

Other Rainy Weather Tips Besides slowing down, other wet weather driving tips include: . Allow extra following distance. . Pass with caution. . Keep windshield wiping

equipment in good shape.

. Keep the windshield washer fluid

reservoir filled.

. Have good tires with proper

tread depth. See Tires on page 10‑54. Turn off cruise control.

Highway Hypnosis Always be alert and pay attention to your surroundings while driving. If you become tired or sleepy, find a safe place to park the vehicle and rest. Other driving tips include: . Keep the vehicle well ventilated. . Keep the interior temperature cool.

. Keep your eyes moving — scan the road ahead and to the sides.

. Check the rearview mirror and

vehicle instruments often.

Hill and Mountain Roads Driving on steep hills or through mountains is different than driving on flat or rolling terrain. Tips for driving in these conditions include: . Keep the vehicle serviced and in

good shape.

. Check all fluid levels and brakes,

tires, cooling system, and transmission.

. Shift to a lower gear when going

down steep or long hills. { WARNING

If you do not shift down, the brakes could get so hot that they would not work well. You would then have poor braking or even none going down a hill. You could crash. Shift down to let the engine assist the brakes on a steep downhill slope.

Driving and Operating

9-11

The Antilock Brake System (ABS) on page 9‑35 improves vehicle stability during hard stops on slippery roads, but apply the brakes sooner than when on dry pavement. Allow greater following distance on any slippery road and watch for slippery spots. Icy patches can occur on otherwise clear roads in shaded areas. The surface of a curve or an overpass can remain icy when the surrounding roads are clear. Avoid sudden steering maneuvers and braking while on ice. Turn off cruise control on slippery surfaces.

{ WARNING

Winter Driving

Driving on Snow or Ice Drive carefully when there is snow or ice between the tires and the road, creating less traction or grip. Wet ice can occur at about 0°C (32°F) when freezing rain begins to fall, resulting in even less traction. Avoid driving on wet ice or in freezing rain until roads can be treated with salt or sand. Drive with caution, whatever the condition. Accelerate gently so traction is not lost. Accelerating too quickly causes the wheels to spin and makes the surface under the tires slick, so there is even less traction. 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.

Coasting downhill in N (Neutral) or with the ignition off is dangerous. The brakes will have to do all the work of slowing down and they could get so hot that they would not work well. You would then have poor braking or even none going down a hill. You could crash. Always have the engine running and the vehicle in gear when going downhill.

. Stay in your own lane. Do not swing wide or cut across the center of the road. Drive at speeds that let you stay in your own lane.

. Be alert on top of hills;

something could be in your lane (stalled car, accident).

. Pay attention to special road

signs (falling rocks area, winding roads, long grades, passing or no-passing zones) and take appropriate action.

Blizzard Conditions Being stuck in snow can be a serious situation. Stay with the vehicle unless there is help nearby. If possible, use the Roadside Assistance Program (U.S. and Canada) on page 13‑8 or Roadside Assistance Program (Mexico) on page 13‑10. To get help and keep everyone in the vehicle safe:

Turn on the hazard warning flashers. Tie a red cloth to an outside mirror.

{ WARNING

Snow can trap engine exhaust under the vehicle. This may cause exhaust gases to get inside. Engine exhaust contains Carbon Monoxide (CO) which cannot be seen or smelled. It can cause unconsciousness and even death.

WARNING (Continued)

WARNING (Continued)

If the vehicle is stuck in the snow: . Clear away snow from around

the base of your vehicle, especially any that is blocking the exhaust pipe.

. Check again from time to

time to be sure snow does not collect there.

. Open a window about

5 cm (2 in) on the side of the vehicle that is away from the wind to bring in fresh air.

. Fully open the air outlets on

or under the instrument panel.

. Adjust the climate control

system to a setting that circulates the air inside the vehicle and set the fan speed to the highest setting. See Climate Control System in the Index.

For more information about carbon monoxide, see Engine Exhaust on page 9‑26. 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 cannot 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 the exhaust.

Run the engine for short periods only as needed to keep warm, but be careful.

(Continued)

To save fuel, run the engine for only short periods as needed to warm the vehicle and then shut the engine off and close the window most of the way to save heat. Repeat this until help arrives but only when you feel really uncomfortable from the cold. Moving about to keep warm also helps. If it takes some time for help to arrive, now and then when you run the engine, push the accelerator pedal slightly so the engine runs faster than the idle speed. This keeps the battery charged to restart the vehicle and to signal for help with the headlamps. Do this as little as possible to save fuel.

Driving and Operating

9-13

If the Vehicle Is Stuck Slowly and cautiously spin the wheels to free the vehicle when stuck in sand, mud, ice, or snow. If stuck too severely for the traction system to free the vehicle, turn the traction system off and use the rocking method.

{ WARNING

If the vehicle's tires spin at high speed, they can explode, and you or others could be injured. The vehicle can overheat, causing an engine compartment fire or other damage. Spin the wheels as little as possible and avoid going above 55 km/h (35 mph).

For information about using tire chains on the vehicle, see Tire Chains on page 10‑76.

Rocking the Vehicle to Get it Out Turn the steering wheel left and right to clear the area around the front wheels. Turn off any traction system. Shift back and forth between R (Reverse) and a forward gear, or with a manual transmission, between 1 (First) or 2 (Second) and R (Reverse), spinning the wheels as little as possible. To prevent transmission wear, wait until the wheels stop spinning before shifting gears. Release the accelerator pedal while shifting, and press lightly on the accelerator pedal when the transmission is in gear. Slowly spinning the wheels in the forward and reverse directions causes a rocking motion that could free the vehicle. If that does not get the vehicle out after a few tries, it might need to be towed out. If the vehicle does need to be towed out, see Towing the Vehicle on page 10‑82.

Vehicle Load Limits It is very important to know how much weight your vehicle can carry. This weight is called the vehicle capacity weight and includes the weight of all occupants, cargo and all nonfactory‐installed options. Two labels on your vehicle show how much weight it may properly carry, the Tire and Loading Information label and the Certification label.

{ WARNING

Do not load the vehicle any heavier than the Gross Vehicle Weight Rating (GVWR), or either the maximum front or rear Gross Axle Weight Rating (GAWR).

WARNING (Continued)

This can cause systems to break and change the way the vehicle handles. This could cause loss of control and a crash. Overloading can also shorten the life of the vehicle.

Tire and Loading Information Label

A vehicle-specific Tire and Loading Information label is attached to the center pillar (B-pillar) of your vehicle. With the driver door open, you will find the label attached below the door latch. This label shows the number of occupant seating positions (A), and the maximum vehicle capacity weight (B) in kilograms and pounds. The Tire and Loading Information label also shows the size of the original equipment tires (C) and the recommended cold tire inflation pressures (D). For more information on tires and inflation see Tires on page 10‑54 and Tire Pressure on page 10‑62.

If your vehicle will be towing a trailer, the load from your trailer will be transferred to your vehicle. Consult this manual to determine how this reduces the available cargo and luggage load capacity of your vehicle. Your vehicle is neither designed nor intended to tow a trailer.

There is also important loading information on the vehicle Certification label. It tells you the Gross Vehicle Weight Rating (GVWR) and the Gross Axle Weight Rating (GAWR) for the front and rear axle. See “Certification Label” later in this section.

Steps for Determining Correct Load Limit 1. Locate the statement

“The combined weight of occupants and cargo should never exceed XXX kg or XXX lbs” on your vehicle's placard.

2. Determine the combined weight of the driver and passengers that will be riding in your vehicle.

3. Subtract the combined weight of the driver and passengers from XXX kg or XXX lbs.

6.

4. The resulting figure equals

the available amount of cargo and luggage load capacity. For example, if the “XXX” amount equals 1400 lbs and there will be five 150 lb passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lbs (1400 − 750 (5 x 150) = 650 lbs).

5. Determine the combined

weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage load capacity calculated in Step 4.

Refer to your vehicle's Tire and Loading Information label for specific information about your vehicle's capacity weight and seating positions. The combined weight of the driver, passengers and cargo should never exceed your vehicle's capacity weight.

Certification Label

It tells you the gross weight capacity of your vehicle, called the Gross Vehicle Weight Rating (GVWR). 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. Do not load your vehicle with more weight than it was designed to carry. See “Steps for Determining Correct Load Limit” earlier in this section.

For the first 800 km (500 mi): . Avoid full throttle starts and

abrupt stops.

. Do not exceed 4000 rpm. . Avoid driving at any one

constant speed, fast or slow, including the use of cruise control.

. Avoid downshifting to brake or

slow the vehicle when the engine speed will exceed 4000 rpm.

. Do not let the engine labor. Never lug the engine in high gear at low speeds. With a manual transmission, shift to the next lower gear. This rule applies at all times, not just during the break-in period.

For the first 2414 km (1500 mi): . Do not participate in track

events, sport driving schools, or similar activities during the first 2414 km (1500 mi).

. Check engine oil with every

refueling and add if necessary. Oil and fuel consumption may be higher than normal during the first 2414 km (1500 mi).

Front Air Dam The vehicle is equipped with a front air dam which has minimal ground clearance. Vehicles with the ZR1 package, or Z06 vehicles with RPO CFZ, also come with a splitter made from carbon fiber.

{ WARNING

ZR1s, and Z06s with RPO CFZ, contain parts made from carbon fiber. When damaged, the exposed edges can be very sharp. A person could be injured by these sharp edges. Use caution when washing the vehicle, coming in contact with, or removing damaged carbon fiber parts. See your dealer for replacement.

Under normal operation, these components will occasionally contact some road surfaces (speed bumps, driveway ramps, etc.). This can be heard inside the vehicle as a scraping noise. This is normal and does not indicate a problem. Use care when approaching bumps or objects on road surfaces and avoid them when possible.

Ignition Positions

The vehicle has an electronic keyless ignition with a push-button start. In order to shift out of P (Park), the vehicle must be running or in Acc. mode and the regular brake pedal must be applied.

/ (START): Press this button while your foot is on the brake for an automatic transmission, or while pressing in the clutch for a manual transmission, to start the engine. If the vehicle is in OFF or Retained Accessory Power (RAP) mode, the Remote Keyless Entry (RKE) transmitter must be inside the vehicle to start the engine. 9 Acc. (STOPPING THE ENGINE/OFF/ACCESSORY): When the vehicle is stopped with the engine on, press the button once to turn the engine off. Do not turn the engine off when the vehicle is moving. This will cause a loss of power assist in the brake and steering systems and disable the airbags.

If the vehicle must be shut off in an emergency: 1. Brake using a firm and steady

pressure. Do not pump the brakes repeatedly. This may deplete power assist, requiring increased brake pedal force.

2. Shift the vehicle to neutral. This can be done while the vehicle is moving. After shifting to neutral, firmly apply the brakes and steer the vehicle to a safe location.

3. Come to a complete stop.

Shift to P (Park) with an automatic transmission, or Neutral with a manual transmission. Turn the ignition to OFF.

Service Only Mode This power mode is available for service and diagnostics, and to verify the proper operation of the malfunction indicator lamp as may be required for emission inspection purposes. With the vehicle off, pressing and holding the bottom of the button for more than five seconds will place the vehicle in Service Only Mode. The instruments and audio systems will operate as they do when the engine is running, but the vehicle will not be able to be driven. The engine will not start in Service Only Mode. Push the button again to turn the vehicle off.

{ WARNING

Turning off the vehicle while moving may cause loss of power assist in the brake and steering systems and disable the airbags. While driving, only shut the vehicle off in an emergency.

If the vehicle cannot be pulled over, and must be shut off while driving, turn the ignition to ACC/ACCESSORY. When the engine is on or the vehicle is in accessory power mode, it is recommended that a manual transmission be placed in R (Reverse). An automatic transmission must be placed in P (Park). Then press the Acc. button to turn the engine off and place the vehicle in RAP. See Retained Accessory Power (RAP) on page 9‑24 for more information.

If an automatic vehicle is not correctly placed in P (Park) a SHIFT TO PARK message will display on the Driver Information Center (DIC). For more information, see Transmission Messages on page 5‑52. When the engine is off, press this button to place the vehicle in accessory mode. ACCESSORY MODE ON will display on the Driver Information Center (DIC). This mode allows you to use things like the radio and the power windows while the engine is off. Use accessory mode if you must have the vehicle in motion while the engine is off, for example, if the vehicle is being pushed or towed. After being in accessory mode for about 10 minutes, the vehicle will automatically enter RAP or OFF, depending on if the doors are opened or closed.

Driving and Operating

Starting the Engine Move the shift lever to P (Park) or N (Neutral) for an automatic transmission. For a manual transmission the vehicle can be started in Neutral or any other gear as long as the clutch pedal is pressed. To restart a vehicle with a manual transmission when you are already moving, use the Neutral position only. To restart a vehicle with an automatic transmission when you are already moving, use N (Neutral). Notice: Do not try to shift to P (Park) if the vehicle is moving. If you do, you could damage the transmission. Shift to P (Park) only when the vehicle is stopped. The RKE transmitter must be inside the vehicle for the ignition to work. Cell phone chargers can interfere with the operation of the Keyless Access System. Battery chargers should not be plugged in when starting or turning off the engine.

To start the vehicle, do the following: 1. For vehicles with an automatic transmission, with your foot on the brake pedal, press the START button located on the instrument panel. For vehicles with a manual transmission, you must also press in the clutch pedal while pressing the START button. If there is not an RKE transmitter in the vehicle or if there is something causing interference with it, the DIC will display NO FOBS DETECTED. See Key and Lock Messages on page 5‑42 for more information.

2. When the engine begins

cranking, let go of the button and the engine cranks automatically until it starts. If the battery in the RKE transmitter is weak, the DIC displays FOB BATTERY LOW. You can still drive the vehicle.

See “Battery Replacement” under Remote Keyless Entry (RKE) System Operation on page 2‑3 for more information. If the fob battery is dead, you need to insert the fob into the fob slot to enable engine starting. See “NO FOBS DETECTED” under Key and Lock Messages on page 5‑42.

immediately after starting it. Operate the engine and transmission gently until the oil warms up and lubricates all moving parts. If the engine does not start and no DIC message is displayed, wait 15 seconds before trying again to let the cranking motor cool down. If the engine does not start after five to 10 seconds, especially in very cold weather (below −18°C or 0°F), it could be flooded with

Chevrolet Corvette Owner Manual - 2012

too much gasoline. Try pushing the accelerator pedal all the way to the floor while cranking for up to 15 seconds maximum. Wait at least 15 seconds between each try, to allow the cranking motor to cool down. When the engine starts, let go of the accelerator. If the vehicle starts briefly but then stops again, repeat these steps. This clears the extra gasoline from the engine.

Notice: Cranking the engine for long periods of time, by pressing the START button immediately after cranking has ended, can overheat and damage the cranking motor, and drain the battery. Wait at least 15 seconds between each try, to allow the cranking motor to cool down.

The vehicle has a Computer- Controlled Cranking System. This feature assists in starting the engine and protects components. Once cranking has been initiated, the engine continues cranking for a few seconds or until the vehicle starts. If the engine does not start, cranking automatically stops after 15 seconds to prevent cranking motor damage. To prevent gear damage, this system also prevents cranking if the engine is already running. Notice: The engine is designed to work with the electronics in the vehicle. If electrical parts or accessories are added, you could change the way the engine operates. Before adding electrical equipment, check with your dealer. If you do not, the engine might not perform properly. Any resulting damage would not be covered by the vehicle warranty.

Stopping the Engine If the vehicle has an automatic transmission, move the shift lever to P (Park) and press and hold the Acc. (Off/Accessory) button, located on the instrument panel, until the engine shuts off. If the shift lever is not in P (Park), the engine shuts off and the vehicle goes into the accessory mode. The DIC displays SHIFT TO PARK. Once the shifter is moved to P (Park), the vehicle turns off. If the vehicle has a manual transmission, it is recommended that you move the shift lever to R (Reverse) and set the parking brake after you turn off the engine by pressing and holding the Acc. (Off/Accessory) button. If the RKE transmitter is not detected inside the vehicle when it is turned to off, the DIC displays NO FOB – OFF OR RUN?.

See if you can move the shift lever away from P (Park) without first pushing the button on the lever. If you can, it means that the shift lever was not fully locked into P (Park). Torque Lock (Automatic Transmission) If you are parking on a hill and you do not shift the transmission into P (Park) properly, the weight of the vehicle may put too much force on the parking pawl in the transmission. You may find it difficult to pull the shift lever out of P (Park). This is called “torque lock.” To prevent torque lock, set the parking brake and then shift into P (Park) properly before you leave the driver seat. To find out how, see “Shifting Into P (Park)” previously in this section.

When you are ready to drive, move the shift lever out of P (Park) before you release the parking brake. If torque lock does occur, you may need to have another vehicle push yours a little uphill to take some of the pressure from the transmission parking pawl, so you can pull the shift lever out of P (Park).

Shifting out of Park Shift lock release prevents shifting out of P (Park) unless the vehicle is running or in accessory mode and the brake pedal is applied. The shift lock release is always functional except in the case of an uncharged or low voltage (less than 9‐volt) battery. See Jump Starting on page 10‑78 for more information.

{ WARNING

It is dangerous to get out of the vehicle if the shift lever is not fully in P (Park) with the parking brake firmly set. The vehicle can roll. Do not leave the vehicle when the engine is running unless you have to. If you have left the engine running, the vehicle can move suddenly. You or others could be injured. To be sure the vehicle will not move, even when you are on fairly level ground, always set the parking brake and move the shift lever to P (Park). See Shifting Into Park (Automatic Transmission) on page 9‑24.

Be sure the shift lever is fully in P (Park) before starting the engine. The vehicle has an automatic transmission shift lock control system. You have to fully apply the

brakes and then press the shift lever button before you can shift from P (Park) when the vehicle is running. If you cannot shift out of P (Park), ease pressure on the shift lever and push the shift lever all the way into P (Park) as you maintain brake application. Then press the shift lever button and move the shift lever into another gear. See Shifting out of Park on page 9‑25. R (Reverse): Use this gear to back up. Notice: Shifting to R (Reverse) while the vehicle is moving forward could damage the transmission. The repairs would not be covered by the vehicle warranty. Shift to R (Reverse) only after the vehicle is stopped. To rock the vehicle back and forth to get out of snow, ice, or sand without damaging the transmission, see If the Vehicle Is Stuck on page 9‑13.

N (Neutral): In this position, the engine does not connect with the wheels. To restart the engine when the vehicle is already moving, use N (Neutral) only. If the vehicle needs towing, see Towing the Vehicle on page 10‑82.

{ WARNING

Shifting into a drive gear while the engine is running at high speed is dangerous. Unless your foot is firmly on the brake pedal, the vehicle could move very rapidly. You could lose control and hit people or objects. Do not shift into a drive gear while the engine is running at high speed.

Notice: Shifting out of P (Park) or N (Neutral) with the engine running at high speed may damage the transmission.

The repairs would not be covered by the vehicle warranty. Be sure the engine is not running at high speed when shifting the vehicle. D (Drive): This position is for normal driving. It provides the best fuel economy. If you need more power for passing, push the pedal down to achieve the desired level of acceleration. Downshifting the transmission in slippery road conditions could result in skidding. See “Skidding” under Loss of Control on page 9‑5. S (Sport Mode): When in S (Sport Mode), the transmission will work as an automatic until you use the Manual Paddle Shift Controls, which activates driver manual gear selection. See Manual Mode on page 9‑29. While in S (Sport Mode), the transmission will have more noticeable upshifts for sportier vehicle performance.

Manual Mode

Manual Paddle Shift While in S (Sport Mode), the paddles located on the steering wheel can be used to manually up-shift or down-shift the transmission.

The Manual Paddle Shift system is activated from S (Sport Mode) by pushing the paddle, above the steering wheel spokes, to up-shift to the next gear, or pulling on the paddle, behind the steering wheel spokes, to down-shift to the next gear.

When accelerating the vehicle from a stop in snowy and icy conditions, you may want to shift to 2 (Second) or 3 (Third) gear. A higher gear allows you to gain more traction on slippery surfaces. If traction control is active, upshifts are delayed to increase your control of the vehicle. See Traction Control System (TCS) on page 9‑36 Traction Control System (TCS). The Manual Paddle Shift system can be deactivated by moving the shift lever from S (Sport Mode) back to D (Drive), or by holding either up‐shift paddle for more than one second. The driver may choose to briefly activate the Manual Paddle Shift system while in D (Drive). Tapping either the upshift or downshift controls will place the transmission in Manual Paddle Shift mode.

Chevrolet Corvette Owner Manual - 2012

Driving and Operating

The driver may then exit Manual Paddle Shift mode by holding either upshift control for more than one second. The system will return to automatic shifting after 10 seconds of cruising at a steady speed and no manual shifts, or when the vehicle comes to a stop. While the Manual Paddle Shift gear selection system is active, the transmission will automatically downshift through the gears as the vehicle slows. The transmission will select 2 (Second) gear as the vehicle stops. From a stop, the vehicle will start from and hold 2 (Second) gear unless the driver manually paddle shifts into a different gear or selects D (Drive). The driver can select 1 (First) gear for maximum acceleration from a stop.

When using the Manual Paddle Shift feature while in S (Sport Mode), the current gear will be displayed in the Driver Information (DIC), or the Head-Up Display (HUD), if the vehicle has either of these features. If the vehicle has a Head-Up Display (HUD), see Head-Up Display (HUD) on page 5‑31. The Manual Paddle Shift system will not allow either an up-shift or a down-shift if the vehicle speed is too fast or too slow, nor will it allow a start from 4 (Fourth) or higher gear. If up-shifting does not occur when needed, vehicle speed will be limited to protect the engine.

When the transmission gear does not respond to a shift change, the DIC will show an X over the gear display.

When a requested shift is denied due to the speed restrictions shown, the DIC will momentarily show an X over the gear display and a chime will sound. If the vehicle has a HUD, and the transmission gear does not respond to a shift change, a chime will sound and the HUD will momentarily show an X over the gear display. Manual Paddle Shift operation is available for use with Cruise Control. See Cruise Control on page 9‑45 Cruise Control for more information.

Manual Transmission

This is the shift pattern for the six-speed manual transmission. Here is how to operate the transmission: 1 (First): Press the clutch pedal and shift into 1 (First). Then slowly let up on the clutch pedal as you press the accelerator pedal.

Neutral: Use this position when you start or idle the engine. The shift lever is in Neutral when it is centered in the shift pattern, not in any gear. R (Reverse): To back up, press down the clutch pedal and shift into R (Reverse). Just apply pressure to get the lever past 5 (Fifth) and 6 (Sixth) into R (Reverse). Let up on the clutch pedal slowly while pressing the accelerator pedal. The six-speed manual transmission has a feature that allows you to safely shift into R (Reverse) while the vehicle is rolling at less than 5 km/h (3 mph). You will be locked out if you try to shift into R (Reverse) while the vehicle is moving faster than 5 km/h (3 mph).

You can shift into 1 (First) when you are going less than 64 km/h (40 mph). If you come to a complete stop and it is hard to shift into 1 (First), put the shift lever in Neutral and let up on the clutch. Press the clutch pedal back down. Then shift into 1 (First). 2 (Second): Press the clutch pedal as you let up on the accelerator pedal and shift into 2 (Second). Then, slowly let up on the clutch pedal as you press the accelerator pedal. 3 (Third), 4 (Fourth), 5 (Fifth) and 6 (Sixth): Shift into 3 (Third), 4 (Fourth), 5 (Fifth) and 6 (Sixth) the same way you do for 2 (Second). Slowly let up on the clutch pedal as you press the accelerator pedal. To stop, let up on the accelerator pedal and press the brake pedal. Just before the vehicle stops, press the clutch pedal and the brake pedal, and shift to Neutral.

Notice: If you skip more than one gear when you downshift, or if you race the engine when you release the clutch pedal while downshifting, you could damage the engine, clutch, driveshaft or the transmission. Do not skip gears or race the engine when downshifting.

The six-speed transmission has a spring that centers the shift lever near 3 (Third) and 4 (Fourth). This spring helps you know which gear you are in when you are shifting. Be careful when shifting from 1 (First) to 2 (Second) or downshifting from 6 (Sixth) to 5 (Fifth). The spring will try to pull the shift lever toward 4 (Fourth) and 3 (Third). Make sure you move the lever into 2 (Second) or 5 (Fifth). If you let the shift lever move in the direction of the pulling, you may end up shifting from 1 (First) to 4 (Fourth) or from 6 (Sixth) to 3 (Third). If the driver does not upshift 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 for more information.

Brakes

Antilock Brake System (ABS) This vehicle has the Antilock Brake System (ABS), an advanced electronic braking system that helps prevent a braking skid. When the engine is started and 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 that 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 the driver 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 might hear the ABS pump or motor operating and feel the brake pedal pulsate, but this is normal. Braking in Emergencies ABS allows the driver to steer and brake at the same time. In many emergencies, steering can help more than even the very best braking.
