winding roads, long grades, passing or no-passing zones) and take appropriate action.

Winter Driving

Driving on Snow or Ice Snow or ice between the tires and the road creates less traction or grip, so drive carefully. Wet ice can occur at about 0 °C (32 °F) when freezing rain begins to fall. Avoid driving on wet ice or in freezing rain until roads can be treated.

For Slippery Road Driving: . Accelerate gently. Accelerating

too quickly causes the wheels to spin and makes the surface under the tires slick.

. Turn on Traction Control. See

Traction Control/Electronic Stability Control 0 192.

(ABS) improves vehicle stability during hard stops, but the brakes should be applied sooner than when on dry pavement. See Antilock Brake System (ABS) 0 189.

. Allow greater following distance 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. Blizzard Conditions Stop the vehicle in a safe place and signal for help. Stay with the vehicle unless there is help nearby. If possible, use Roadside Assistance. See Roadside Assistance Program 0 319. To get help and keep everyone in the vehicle safe:

Driving and Operating

. 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. If the vehicle is stuck in snow:

. Clear snow from the base of

the vehicle, especially any blocking the exhaust pipe. . Open a window about 5 cm

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

. Fully open the air outlets on

or under the instrument panel.

(Continued)

Warning (Continued)

. Adjust the climate control system to circulate the air inside the vehicle and set the fan speed to the highest setting. See “Climate Control Systems.”

For more information about CO, see Engine Exhaust 0 181.

To save fuel, run the engine for short periods to warm the vehicle and then shut the engine off and partially close the window. Moving about to keep warm also helps. If it takes time for help to arrive, when running 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.

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. See Traction Control/Electronic Stability Control 0 192.

{ 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 56 km/h (35 mph).

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

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 low forward gear, 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 0 287.

Vehicle Load Limits It is very important to know how much weight the 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 the vehicle may 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). 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 reduce stopping distance, damage the tires, and shorten the life of the vehicle.

Tire and Loading Information Label

Label Example

A vehicle-specific Tire and Loading Information label is attached to the center pillar (B-pillar). This label shows the number of occupant seating positions (1), and the maximum vehicle capacity weight (2) in kilograms and pounds. The Tire and Loading Information label also shows the size of the original equipment tires (3) and the recommended cold tire inflation pressures (4).

Driving and Operating

For more information on tires and inflation see Tires 0 254
and Tire Pressure 0 262. There is also important loading information on the vehicle Certification label. It may show 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.

6.

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

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. If your vehicle will be towing a trailer, 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.”

Starting and Operating

New Vehicle Break-In Follow these recommended guidelines during the first 2 414 km (1,500 mi) of driving this vehicle. Parts have a break-in period and performance will be better in the long run. For the first 322 km (200 mi): . To break in new tires, drive at

moderate speeds and avoid hard cornering.

. New brake linings also need a break-in period. Avoid making hard stops. This is recommended every time brake linings are replaced.

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

abrupt stops.

. Do not exceed 4000 rpm.

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

. 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. With a manual transmission, shift to the next lower gear. This rule applies at all times, not just during the break-in period.

. After the first 800 km (500 mi),

change the engine oil on vehicles with the LT1 engine and Z51 package, or the LT4 engine.

For the first 2 414 km (1,500 mi): . Do not participate in track

events, sport driving schools, or similar activities.

. Check engine oil with every

refueling and add if necessary. Oil and fuel consumption may be higher than normal.

Front Air Dam If equipped, the front air dam has minimal ground clearance. Under normal operation, the 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.

Carbon Fiber This vehicle may be equipped with carbon fiber parts. Dealer-installed accessories may also contain carbon fiber. Some vehicles have a carbon fiber splitter and rocker extension. Do not stand on the rocker extension or use it as a step, as it could break.

176

Driving and Operating

The vehicle has an electronic keyless ignition with pushbutton start. Pressing the button cycles it through three modes: ACC/ACCESSORY, ON/RUN/START, and Stopping the Engine/OFF. The Remote Keyless Entry (RKE) transmitter must be in the vehicle for the system to operate. If the pushbutton start is not working, the vehicle may be near a strong radio antenna signal causing interference to the Keyless Access system. See Remote Keyless Entry (RKE) System Operation 0 26. To shift out of P (Park), the vehicle must be in ON/RUN and the brake pedal must be applied. Stopping the Engine/OFF (No Indicator Lights) : When the vehicle is stopped, press the ENGINE START/STOP button once to turn the engine off.

If the vehicle is in P (Park), the ignition will turn off, and Retained Accessory Power (RAP) will remain active. See Retained Accessory Power (RAP) 0 179.

Automatic Transmission If the vehicle is not in P (Park), the ignition will return to ACC/ ACCESSORY and display a message in the Driver Information Center (DIC). See Transmission Messages 0 129. When the vehicle is shifted into P (Park), the ignition system will switch to OFF.

Manual Transmission If the vehicle is stationary, the ignition will turn OFF, and Retained Accessory Power (RAP) will remain active. See Retained Accessory Power (RAP) 0 179. 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 N (Neutral).

This can be done while the vehicle is moving. After shifting to N (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 Stopping the Engine/OFF.

4. Set the parking brake. See

Electric Parking Brake 0 190.

{ 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, press and hold the ENGINE START/ STOP button for longer than two seconds, or press twice within five seconds. ACC/ACCESSORY (Amber Indicator Light) : This mode allows the use of some electrical accessories when the engine is off. With the ignition off, pressing the button one time without the brake pedal applied will place the ignition system in ACC/ACCESSORY. The ignition will switch from ACC/ ACCESSORY to Stopping the Engine/OFF after five minutes to prevent battery rundown. ON/RUN/START (Green Indicator Light) : This mode is for driving and starting. With the ignition off, and the brake pedal applied, pressing the button once will place the ignition system in ON/RUN/START. Once engine cranking begins, release the button. Engine cranking will continue until the engine starts. See Starting the Engine 0 177. The ignition will then remain in ON/RUN.

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, and the brake pedal not applied, pressing and holding 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 in ON/RUN, but the vehicle will not be able to be driven. The engine will not start in Service Only Mode. Press the button again to turn the vehicle off.

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 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.

Caution

Cranking the engine for long periods of time, by returning the ignition to the START position 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 let the cranking motor cool down.

Leaving the Vehicle with the Engine Running (Automatic Transmission)

{ Warning

It can be dangerous to leave the vehicle with the engine running. It could overheat and catch fire. 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. 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 0 179.

If you have to leave the vehicle with the engine running, be sure the vehicle is in P (Park) and the parking brake is firmly set before

Driving and Operating

you leave it. After you have moved the shift lever into P (Park), hold down the regular brake pedal. 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 - North America 0 284. To shift out of P (Park): 1. Apply the brake pedal. 2. Release the parking brake.

See Electric Parking Brake 0 190.

3. Press the shift lever button. 4. Move the shift lever to the

desired position.

If you still are unable to shift out of P (Park): 1. Fully release the shift lever

button, and let go of the shift knob.

2. While holding down the brake

pedal, press the shift lever button again.

3. Move the shift lever to the

desired position.

If you still cannot move the shift lever from P (Park), consult your dealer or a professional towing service.

Parking (Manual Transmission) Before exiting the vehicle, move the shift lever into 1 (First) or R (Reverse), and apply the parking brake. Once the shift lever has been placed into 1 (First) or R (Reverse) with the clutch pedal pressed in, turn the ignition off and release the clutch.

Driving and Operating

D : This position is for normal driving. It provides the best fuel economy. If more power is needed 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 0 161. The transmission can be shifted like a manual transmission using the paddle shift controls while in D (Drive). See Manual Mode 0 184. M : In M (Manual Mode), the transmission can be shifted like a manual transmission using the paddle shift controls. See Manual Mode 0 184.

Manual Mode

Manual Paddle Shift

When using the Manual Paddle Shift feature while in M (Manual Mode), the current gear will be displayed in the instrument cluster, or the Head-Up Display (HUD), if equipped. See Head-Up Display (HUD) 0 115. When accelerating the vehicle from a stop in snowy and icy conditions, shifting to 2 (Second) gear allows the vehicle to gain more traction. The Manual Paddle Shift system can be deactivated by moving the shift lever from M (Manual Mode) back to D (Drive).

When the shift lever is moved to M (Manual Mode), the transmission enters Manual Mode. The transmission will hold the current gear until a change is requested. The paddles on the steering wheel can be used to manually upshift or downshift the transmission. The right (+) plus paddle upshifts, and the left (−) minus paddle downshifts.

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

select 1 (First) gear as the vehicle stops. From a stop, the vehicle will start from and hold 1 (First) gear unless the manual paddle shifts are used to shift into a different gear, or D (Drive) is selected. If the left (−) minus paddle is held down briefly, the transmission will downshift to the lowest gear possible for the vehicle speed. If the paddle continues to be held as the vehicle slows, downshifts will continue to occur as vehicle speed allows. This feature also works while in Temporary Manual Paddle Shift mode, but the driver must first press and release the (−) minus paddle to enter Temporary Manual Paddle Shift mode, then press and hold the (−) minus paddle briefly. The Manual Paddle Shift system will not allow either an upshift or a downshift if the vehicle speed is too fast or too slow, nor will it allow a start from 3 (Third) or higher gear. If upshifting does not occur when needed, vehicle speed will be limited to protect the engine.

Driving and Operating

185

When a requested shift is denied due to the speed restrictions shown, a DIC message will be displayed, and the current gear remains displayed in the cluster and HUD. Manual Paddle Shift operation is available for use with cruise control. See Cruise Control 0 202. The vehicle speeds required for Manual Paddle Shift upshifts depend on several vehicle inputs, which will vary the allowed up-shift speed by a few km/h (mph).

For Vehicles with a 2.41:1 Axle Ratio (RPO GXB) . Upshifts to 3 (Third) gear require approximately 25 km/h (16 mph).

. Upshifts to 4 (Fourth) gear

require approximately 37 km/h (23 mph).

. Upshifts to 5 (Fifth) gear require approximately 48 km/h (30 mph). . Upshifts to 6 (Sixth) gear require approximately 60 km/h (37 mph).

. Upshifts to 7 (Seventh) gear

require approximately 74 km/h (46 mph).

When the shift lever is in D (Drive), press either the right (+) plus paddle or the left (−) minus paddle to place the transmission in Temporary Manual Paddle Shift mode. The gear indicator by the shift lever, in the cluster, and in the HUD will display an M, even though the shift lever is still in D (Drive). To exit the system, hold the (+) plus paddle for more than one second. The system will return to automatic shifting after six seconds of cruising at a steady speed, no manual shifts, no aggressive cornering, 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

Manual Transmission

To operate: 1 : Press the clutch pedal and shift into 1 (First). Then slowly let up on the clutch pedal as the accelerator pedal is pressed. This can be done if the vehicle is going less than 64 km/h (40 mph). If the vehicle is at a complete stop and it is hard to shift into 1 (First), put the shift lever in Neutral and let up on the clutch. Then press the clutch pedal back down and shift into 1 (First).

2 : Press the clutch pedal while letting up on the accelerator pedal and shift into 2 (Second). Then, slowly let up on the clutch pedal as the accelerator pedal is pressed. 3, 4, 5, 6, and 7 : Shift into 3 (Third), 4 (Fourth), 5 (Fifth), 6 (Sixth), and 7 (Seventh) the same way as for 2 (Second). 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. Neutral : Use to start or idle the engine. Neutral is the center position of the shift pattern. R : To back up, push the clutch pedal and shift into R (Reverse). Additional pressure may be needed to move the lever past 5 (Fifth) and 6 (Sixth) into R (Reverse). Let up on the clutch pedal slowly while pressing the accelerator pedal.

Driving and Operating

187

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).

3 (Third)

4 (Fourth)

72 km/h (45 mph) 107 km/h (67 mph)

160 km/h (100 mph) 233 km/h (145 mph)

Caution

When downshifting, if more than one gear is skipped, or the engine is racing when the clutch pedal is 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 shutoff rpm, the engine speed will be limited to protect the engine. See Tachometer 0 101.

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.

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

ARM will also: . Be active above 14 km/h (9 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).

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 (Check Engine Light) 0 106. The clutch and manual transmission will continue to operate normally.

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 0 109.

Driving and Operating

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. The system has a red parking brake status light and an amber parking brake warning light. See Electric Parking Brake Light 0 108 and Service Electric Parking Brake Light 0 109. There are also parking brake-related Driver Information Center (DIC) messages. See Brake System Messages 0 120. 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.

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

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 0 108. 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 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/ START 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

Driving and Operating

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 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).

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.

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

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 0 202. 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 0 170
and “Turning the Systems Off and On” later in this section.

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.

To turn off both TCS and StabiliTrak, press and hold the g button until the Traction Off light i and StabiliTrak OFF light g illuminate and stay on in the instrument cluster.

To turn TCS and StabiliTrak on again, press and release the g button. The Traction Off light i and StabiliTrak OFF light g in the instrument cluster turn off. If the Tire Pressure Monitor System (TPMS) system is malfunctioning and the DIC displays SERVICE TIRE MONITOR SYSTEM, StabiliTrak will be affected as follows: . StabiliTrak cannot be turned off

by the driver. If StabiliTrak is off, it will be turned on automatically.

. Competitive Driving Mode or

Performance Traction Management is unavailable.

. StabiliTrak will feel different in

aiding and maintaining directional control.

Adding accessories can affect the vehicle performance. See Accessories and Modifications 0 213.

Driving and Operating

Competitive Driving Mode If equipped, 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 StabiliTrak systems on.
