1 (Defrost): This mode clears the windows of fog or frost more quickly. Air is directed to the windshield, with a small amount directed to the side window outlets. The indicator light comes on and the digital display will show the defrost mode symbol and fan speed when the front defrost mode is being used. In this mode, the system automatically turns off the recirculation and runs the air conditioning compressor, unless the outside temperature is at or below freezing. Recirculation cannot be selected while in the defrost mode. Pressing 1 again will return the system to the last operating mode. For severe ice conditions, turn the driver's temperature knob to 32°C (90°F) while in defrost mode. Do not drive the vehicle until all the windows are clear.

^ (Air Conditioning Off): Press to turn the air conditioning compressor off. Press AUTO to return to automatic operation. When in AUTO, the air conditioning compressor comes on automatically, as needed. Air conditioning does not operate at temperatures below about 2°C to 4°C (35°F to 40°F). In temperatures above 4°C (40°F), the air conditioning cannot be turned off in defrost and defog, as it helps to remove moisture from the vehicle. It also helps to keep the windows clear. You may notice a slight change in engine performance when the air conditioning compressor shuts off and turns on again. This is normal. The system is designed to make adjustments to help with fuel economy while still maintaining the selected temperature.

On hot days, open the windows to let hot inside air escape; then close them. This helps to reduce the time it takes for the vehicle to cool down. It also helps the system to operate more efficiently. For quick cool down on hot days press the AUTO button and adjust the temperature to a cool, comfortable setting. To achieve maximum cool down, do the following: 1. Select H mode. 2. Press ?. 3. Select the a/c on. 4. Select the coolest temperature. 5. Select the highest fan speed.

Chevrolet Corvette Owner Manual - 2011

Using these settings together for long periods of time may cause the air inside of your vehicle to become too dry. To prevent this from happening, after the air in the vehicle has cooled, turn the recirculation mode off. The air conditioning system removes moisture from the air, so a small amount of water might drip under the vehicle while idling or after turning off the engine. This is normal. ? (Recirculation): Press to turn the recirculation mode on or off. An indicator light comes on to show that recirculation is on. This mode prevents outside air from entering your vehicle. It can be used to prevent outside air and odors from entering your vehicle and to help cool the air inside your vehicle more quickly. Recirculation mode is not available in defrost or defog mode.

Sensors The solar sensor on the vehicle monitors the solar heat and uses the information to maintain the selected temperature when operating in AUTO mode by automatically adjusting the temperature, fan speed, and air delivery system. The system may also supply cooler air to the side of the vehicle facing the sun. The recirculation mode will also be activated, as necessary. Do not cover the solar sensor located on the top of the instrument panel near the windshield or the system will not work properly. There is also a sensor located behind the front bumper. This sensor reads the outside air temperature and helps to maintain the temperature inside the vehicle. Any cover on the front of the vehicle could give a false reading in the temperature.

If the outside temperature goes up, the displayed temperature will not change until:

The vehicle's speed is above 19 km/h (12 mph) for five minutes. The vehicle's speed is above 52 km/h (32 mph) for two and one‐half minutes.

These delays prevent false readings. If the temperature goes down, the outside temperature will be shown when you start the vehicle. If it has been turned off for less than three hours, the temperature will be recalled from the previous vehicle operation. There is also an inside temperature sensor located to the left of the ignition switch. The automatic climate control system uses this sensor to receive information, so if you block or cover it, the system will not function properly.

Rear Window Defogger The rear window defogger uses a warming grid to remove fog or frost from the rear window. The rear window defogger only works when the engine is running. = (Rear Window Defogger): Press to turn the rear window defogger on or off. Be sure to clear as much snow from the rear window as possible. An indicator light comes on to show that the rear window defogger is on. The rear window defogger turns off about 10 minutes after the button is pressed when traveling less than 48 km/h (30 mph). If turned on again, the defogger only runs for about five minutes before turning off. The defogger can also be turned off by turning off the engine.

The vehicle has heated outside rearview mirrors. The mirrors will heat to help clear fog or frost from the surface of the mirrors when the rear window defogger button is pressed. For vehicles with a power convertible top, the rear window defogger and heated mirrors are automatically disabled when the power convertible top is moving or down. Notice: Do not use anything sharp on the inside of the rear window. If you do, you could cut or damage the warming grid, and the repairs would not be covered by the vehicle warranty. Do not attach a temporary vehicle license, tape, a decal, or anything similar to the defogger grid.

Air Vents Use the tab located on the air outlets to change the direction of the airflow.

Operation Tips . Clear away any ice, snow,

or leaves from the air inlets at the base of the windshield that may block the flow of air into your vehicle.

. Use of non-GM approved hood deflectors may adversely affect the performance of the system. . Keep the area around the base of the instrument panel console and air path under the seats clear of objects to help circulate the air inside of your vehicle more effectively.

Maintenance

Passenger Compartment Air Filter The passenger compartment air filter removes certain particles from the air including pollen and dust particles. Reductions in airflow, which may occur more often in dusty areas, indicate that the filter may need to be replaced. See Maintenance Replacement Parts on page 11‑8. Notice: Driving without a passenger compartment air filter in place can cause water and small particles, like paper and leaves, to be pulled into your climate control system which may cause damage to it. Make sure you always replace the old filter with a new one.

The passenger compartment air filter is located on the passenger side of the engine compartment near the battery. See Engine Compartment Overview on page 10‑10. To check or replace the air filter:

1. Remove the cover retainer

clips (A) from the passenger compartment air filter cover.

2. Remove the cover.

3. Remove the filter and install the

new air filter.

4. Replace the filter cover. 5. Attach the retainer clips.

Driving Information

Defensive Driving Defensive driving means “always expect the unexpected.” The first step in driving defensively is to wear the safety belt. See Safety Belts on page 3‑9.

{ WARNING

Assume that other road users (pedestrians, bicyclists, and other drivers) are going to be careless and make mistakes. Anticipate what they might do and be ready. In addition:

. Allow enough following

distance between you and the driver in front of you.

. Focus on the task of driving.

(Continued)

WARNING (Continued)

Driver distraction can cause collisions resulting in injury or possible death. These simple defensive driving techniques could save your life.

Drunk Driving

{ WARNING Drinking and then driving is very dangerous. Your reflexes, perceptions, attentiveness, and judgment can be affected by even a small amount of alcohol. You can have a serious — or even fatal — collision if you drive after drinking. Do not drink and drive or ride with a driver who has been drinking. Ride home in a cab; or if you are with a group, designate a driver who will not drink.

Death and injury associated with drinking and driving is a global tragedy. Alcohol affects four things that anyone needs to drive a vehicle: judgment, muscular coordination, vision, and attentiveness. Police records show that almost 40 percent of all motor vehicle-related deaths involve alcohol. In most cases, these deaths are the result of someone who was drinking and driving. In recent years, more than 17,000 annual motor vehicle-related deaths have been associated with the use of alcohol, with about 250,000 people injured.

Chevrolet Corvette Owner Manual - 2011

Black plate (3,1)

For persons under 21, it is against the law in every U.S. state to drink alcohol. There are good medical, psychological, and developmental reasons for these laws. The obvious way to eliminate the leading highway safety problem is for people never to drink alcohol and then drive. Medical research shows that alcohol in a person's system can make crash injuries worse, especially injuries to the brain, spinal cord, or heart. This means that when anyone who has been drinking — driver or passenger — is in a crash, that person's chance of being killed or permanently disabled is higher than if the person had not been drinking.

Driving and Operating

9-3

Average reaction time is about three‐fourths of a second. But that is only an average. It might be less with one driver and as long as two or three seconds or more with another. Age, physical condition, alertness, coordination, and eyesight all play a part. So do alcohol, drugs, and frustration. But even in three‐fourths of a second, a vehicle moving at 100 km/h (60 mph) travels 20 m (66 feet). That could be a lot of distance in an emergency, so keeping enough space between the vehicle and others is important. And, of course, actual stopping distances vary greatly with the surface of the road, whether it is pavement or gravel; the condition of the road, whether it is wet, dry, or icy; tire tread; the condition of the brakes; the weight of the vehicle; and the amount of brake force applied.

Control of a Vehicle The following three systems help to control the vehicle while driving — brakes, steering, and accelerator. At times, as when driving on snow or ice, it is easy to ask more of those control systems than the tires and road can provide. Meaning, you can lose control of the vehicle. See Traction Control System (TCS) on page 9‑36 and Active Handling System on page 9‑37. Adding non‐dealer accessories can affect vehicle performance. See Accessories and Modifications on page 10‑4.

Braking See Brake System Warning Light on page 5‑21. Braking action involves perception time and reaction time. Deciding to push the brake pedal is perception time. Actually doing it is reaction time.

Chevrolet Corvette Owner Manual - 2011

9-4

Driving and Operating

Avoid needless heavy braking. Some people drive in spurts, heavy acceleration followed by heavy braking, rather than keeping pace with traffic. This is a mistake. The brakes might not have time to cool between hard stops. The brakes will wear out much faster with a lot of heavy braking. Keeping pace with the traffic and allowing realistic following distances eliminates a lot of unnecessary braking. That means better braking and longer brake life. If the engine ever stops while the vehicle is being driven, brake normally but do not pump the brakes. If the brakes are pumped, the pedal could get harder to push down. If the engine stops, there will still 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.

Under certain weather or operating conditions, occasional brake squeak, squeal, or other noise might be heard with the vehicle's performance braking system. This brake system is designed for superior fade resistance and consistent operation using high performance brake pads. Brake noise and brake dust are normal and do not affect system performance. Adding non‐dealer accessories can affect vehicle performance. See Accessories and Modifications on page 10‑4.

Steering

Power Steering If power steering assist is lost because the engine stops or the system is not functioning, the vehicle can be steered but it will take more effort.

Magnetic Speed Variable Assist Steering System 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. Steering Tips It is important to take curves at a reasonable speed. Traction in a curve depends on the condition of the tires and the road surface, the angle at which the curve is banked, and vehicle speed. While in a curve, speed is the one factor that can be controlled. If there is a need to reduce speed, do it before entering the curve, while the front wheels are straight. Try to adjust the speed so you can drive through the curve. Maintain a reasonable, steady speed. Wait to accelerate until out of the curve, and then accelerate gently into the straightaway.

Chevrolet Corvette Owner Manual - 2011

Black plate (5,1)

Steering in Emergencies There are times when steering can be more effective than braking. For example, you come over a hill and find a truck stopped in your lane, or a car suddenly pulls out from nowhere, or a child darts out from between parked cars and stops right in front of you. These problems can be avoided by braking — if you can stop in time. But sometimes you cannot stop in time because there is no room. That is the time for evasive action — steering around the problem. The vehicle can perform very well in emergencies like these. First apply the brakes. See Braking on page 9‑3. It is better to remove as much speed as possible from a collision. Then steer around the problem, to the left or right depending on the space available.

Driving and Operating

9-5

Off-Road Recovery The vehicle's right wheels can drop off the edge of a road onto the shoulder while driving.

An emergency like this requires close attention and a quick decision. If holding the steering wheel at the recommended 9 and 3 o'clock positions, it can be turned a full 180 degrees very quickly without removing either hand. But you have to act fast, steer quickly, and just as quickly straighten the wheel once you have avoided the object. The fact that such emergency situations are always possible is a good reason to practice defensive driving at all times and wear safety belts properly.

If the level of the shoulder is only slightly below the pavement, recovery should be fairly easy. Ease off the accelerator and then, if there is nothing in the way, steer so that the vehicle straddles the edge of the pavement.

Chevrolet Corvette Owner Manual - 2011

Black plate (6,1)

9-6

Driving and Operating

Turn the steering wheel 8 to 13 cm (3 to 5 in), about one-eighth turn, until the right front tire contacts the pavement edge. Then turn the steering wheel to go straight down the roadway.

Loss of Control Let us review what driving experts say about what happens when the three control systems — brakes, steering, and acceleration — do not have enough friction where the tires meet the road to do what the driver has asked. In any emergency, do not give up. Keep trying to steer and constantly seek an escape route or area of less danger.

Skidding In a skid, a driver can lose control of the vehicle. Defensive drivers avoid most skids by taking reasonable care suited to existing conditions, and by not overdriving those conditions. But skids are always possible. The three types of skids correspond to the vehicle's three control systems. In the braking skid, the wheels are not rolling. In the steering or cornering skid, too much speed or steering in a curve causes tires to slip and lose cornering force. And in the acceleration skid, too much throttle causes the driving wheels to spin. If the vehicle starts to slide, ease your foot off the accelerator pedal and quickly steer the way you want the vehicle to go. If you start steering quickly enough, the vehicle may straighten out. Always be ready for a second skid if it occurs.

Of course, traction is reduced when water, snow, ice, gravel, or other material is on the road. For safety, slow down and adjust your driving to these conditions. It is important to slow down on slippery surfaces because stopping distance is longer and vehicle control more limited. While driving on a surface with reduced traction, 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. You might not realize the surface is slippery until the vehicle is skidding. 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. 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 10‑15. ZO6, ZR1, and Grand Sport 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 ZO6, ZR1, and Grand Sport: 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. ZO6, ZR1, and Grand Sport 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.

Driving and Operating

9-7

ZO6, ZR1, and Grand Sport 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). If the vehicle is a ZO6, ZR1, or Grand Sport 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 Scheduled Maintenance on page 11‑2 and Recommended Fluids and Lubricants on page 11‑6. 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 13‑15.

Chevrolet Corvette Owner Manual - 2011

Driving and Operating

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 11‑6 for what fluid to use. ZR1 Brake Burnish Procedure Notice: These procedures are specific to the ZR1 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 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 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 - 2011

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.

(Continued)

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.

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 10‑58. 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 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.

{ WARNING

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.

Chevrolet Corvette Owner Manual - 2011

Black plate (11,1)

. 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. Top of hills: Be alert — 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.

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.

Driving and Operating

9-11

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. The Antilock Brake System (ABS) on page 9‑34 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.

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.

(Continued)

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.

(Continued)

. 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. 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.

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 10‑80.

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 10‑86.

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). 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

Label Example

A vehicle specific Tire and Loading Information label is attached to the center pillar (B-pillar) of your vehicle. With the driver's 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.

Chevrolet Corvette Owner Manual - 2011

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 10‑58 and Tire Pressure on page 10‑66. 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.

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

6.

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, 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.

Starting and Operating

New Vehicle Break-In Follow these recommended guidelines during the first 2 414 km (1,500 miles) 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 miles):

To break in new tires, drive at moderate speeds and avoid hard cornering for the first 322 km (200 miles).

. New brake linings also need a break- in period. Avoid making hard stops during the first 322 km (200 miles). This is recommended every time brake linings are replaced.

Chevrolet Corvette Owner Manual - 2011

Driving and Operating

9-19

For the first 80 km (500 miles): . Avoid full throttle starts and

abrupt stops.

. Do not exceed 4,000 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 2 414 km (1,500 miles): . Do not participate in track

events, sport driving schools, or similar activities during the first 2 414 km (1,500 miles). . Check engine oil with every

refueling and add if necessary. Oil and fuel consumption may be higher than normal during the first 2 414 km (1,500 miles).

Front Air Dam The vehicle is equipped with a front air dam which has minimal ground clearance. Vehicles with the ZR1 package, or ZO6 vehicles with RPO ULZ, also come with a splitter made from carbon fiber.

{ WARNING

ZR1s, and ZO6s with RPO ULZ, 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.

In an emergency, if the vehicle must be shut off while driving: 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.

4. Set the parking brake. See

Parking Brake on page 9‑35

Chevrolet Corvette Owner Manual - 2011

Black plate (21,1)

{ 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.

5.

If the vehicle 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 9‑23 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 5‑53. 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

9-21

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.

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.

3. Do not race the engine

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 5-10 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.

Chevrolet Corvette Owner Manual - 2011

Shifting Into Park (Automatic Transmission)

{ WARNING

It can be 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. 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, use the steps that follow.

1. Hold the brake pedal down

and set the parking brake. See Parking Brake on page 9‑35 for more information.

2. Move the shift lever into P (Park)

by holding in the button on the lever and pushing the lever all the way toward the front of the vehicle.

3. Press the Acc. button (ignition switch) to turn the engine off.

Leaving the Vehicle with the Engine Running (Automatic Transmission)

{ WARNING

It can be dangerous to leave the vehicle with the engine running. The vehicle could move suddenly if the shift lever is not fully in P (Park) with the parking brake firmly set. And, if you leave the vehicle with the engine running, it could overheat and even catch fire. You or others could be injured. Do not leave the vehicle with the engine running.

Chevrolet Corvette Owner Manual - 2011

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 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).

Driving and Operating

9-25

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 10‑82 for more information.
