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 10-74.

To shift out of P (Park): 1. Apply the brake pedal. 2. Release the parking brake. See

Electric Parking Brake on page 9-34.

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.

Parking over Things That Burn

{ Warning

Things that can burn could touch hot exhaust parts under the vehicle and ignite. Do not park over papers, leaves, dry grass, or other things that can burn.

Active Fuel Management® This system allows the engine to operate on either all or half of its cylinders, depending on the driving conditions. With a manual transmission, the system is only active in Eco mode. With an automatic transmission, the system is available in all modes, but is more aggressive in Eco mode. See Driver Mode Control on page 9-39. When less power is required, such as cruising at a constant vehicle speed, the system will operate in the half cylinder mode, allowing the vehicle to achieve better fuel economy. When greater power demands are required, such as accelerating from a stop, passing, or merging onto a freeway, the system will maintain full-cylinder operation.

Engine Exhaust { Warning

Engine exhaust contains carbon monoxide (CO) which cannot be seen or smelled. Exposure to CO can cause unconsciousness and even death. Exhaust may enter the vehicle if:

. The vehicle idles in areas

with poor ventilation (parking garages, tunnels, deep snow that may block underbody airflow or tail pipes).

. The exhaust smells or

sounds strange or different.

. The exhaust system leaks

due to corrosion or damage. . The vehicle exhaust system

has been modified, damaged, or improperly repaired.

Driving and Operating

Warning (Continued)

. There are holes or openings

in the vehicle body from damage or aftermarket modifications that are not completely sealed.

If unusual fumes are detected or if it is suspected that exhaust is coming into the vehicle:

. Drive it only with the windows

completely down.

. Have the vehicle repaired

immediately.

Never park the vehicle with the engine running in an enclosed area such as a garage or a building that has no fresh air ventilation.

Automatic Transmission

Running the Vehicle While Parked It is better not to park with the engine running. If the vehicle is left with the engine running, follow the proper steps to be sure the vehicle will not move. See Shifting Into Park on page 9-23
and Engine Exhaust on page 9-25. If the vehicle has a manual transmission, see Parking (Manual Transmission) on page 9-25.

There are several different positions for the shift lever. P (Park): This position locks the rear wheels. It is the best position to use when starting the engine because the vehicle cannot move easily.

{ 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. 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 on page 9-23.

Be sure the shift lever is fully in P (Park) before starting the engine.

Driving and Operating

9-27

The vehicle has an automatic transmission shift lock control system. Fully apply the brakes and then press the shift lever button before shifting from P (Park) when the vehicle is running. If the vehicle cannot be shifted out of P (Park), ease pressure on the shift lever and push the shift lever all the way into P (Park) as brake application is maintained. Then press the shift lever button and move the shift lever into another gear. See Shifting out of Park on page 9-24. R (Reverse): Use this gear to back up.

{ Caution

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 10-77.

{ 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.

{ Caution 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 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 on page 9-5. The transmission can be shifted like a manual transmission using the paddle shift controls while in D (Drive). See Manual Mode on page 9-28.

In

M (Manual Mode): M (Manual Mode), the transmission can be shifted like a manual transmission using the paddle shift controls. See Manual Mode on page 9-28.

Manual Mode

Manual Paddle Shift

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

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) on page 5-26. When accelerating the vehicle from a stop in snowy and icy conditions, shifting to 2 (Second) or 3 (Third) gear allows the vehicle to gain more traction.

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.

Driving and Operating

9-29

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 in D (Drive), press either the right (+) plus paddle or the left (−) minus paddle to place the transmission in 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

select 2 (Second) gear as the vehicle stops. From a stop, the vehicle will start from and hold 2 (Second) gear unless the manual paddle shifts are used to shift into a different gear, or D (Drive) is selected. The driver can select 1 (First) gear for maximum acceleration from a stop. 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 4 (Fourth) or higher gear. If upshifting does not occur when needed, vehicle speed will be limited to protect the engine. 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 on page 9-47. 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 2.56:1 Axle Ratio (RPO GM8 without Z51) . Upshifts to 4 (Fourth) gear

require approximately 35 km/h (22 mph).

. Upshifts to 5 (Fifth) gear require approximately 45 km/h (28 mph). . Upshifts to 6 (Sixth) gear require approximately 65 km/h (41 mph).

Driving and Operating

To prevent damage to the powertrain, Manual Paddle downshifts to a lower gear cannot be done above certain speeds. The maximum speed allowed for downshifting of gears 1 (First) through 4 (Fourth) are:

Into 4 (Fourth) gear over 234 km/h (145 mph). Into 3 (Third) gear over 176 km/h (109 mph). Into 2 (Second) gear over 113 km/h (70 mph). Into 1 (First) gear over 64 km/h (40 mph).

If an upshift is not requested as the engine speed approaches fuel shut off rpm, the engine speed will be limited to protect the engine. See Tachometer on page 5-11.

To prevent damage to the powertrain, Manual Paddle downshifts to a lower gear cannot be done above certain speeds. The maximum speed allowed for downshifting of gears 1 (First) through 4 (Fourth) are:

Into 4 (Fourth) gear over 250 km/h (155 mph). Into 3 (Third) gear over 188 km/h (117 mph). Into 2 (Second) gear over 120 km/h (75 mph). Into 1 (First) gear over 68 km/h (42 mph).

For vehicles with a 2.73:1 Axle Ratio (RPO GU2 with Z51) . Upshifts to 4 (Fourth) gear

require approximately 31 km/h (19 mph).

. Upshifts to 5 (Fifth) gear require approximately 39 km/h (24 mph). . Upshifts to 6 (Sixth) gear require approximately 57 km/h (35 mph).

Manual Transmission

This is the 7-speed manual transmission shift pattern. To operate: 1 (First): 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 (Second): 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 (Third), 4 (Fourth), 5 (Fifth), 6 (Sixth), and 7 (Seventh): 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 (Reverse): 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. 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.

Driving and Operating

{ 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 shut off rpm, the engine speed will be limited to protect the engine. See Tachometer on page 5-11.

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.

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.

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

gear number is amber.

. When ARM is deactivated, the

gear number is white.

. A white dash indicates that

service is required. ARM will be disabled, and the malfunction indicator lamp will be on. See Malfunction Indicator Lamp on page 5-15. The clutch and manual transmission will continue to operate normally.

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

(20 mph).

. Match engine speed up to

5400 rpm.

. Not operate when the

accelerator pedal is applied.

. Be disabled when the coolant

temperature is below 0°C (32°F).

If there is a problem with ABS, this warning light stays on. See Antilock Brake System (ABS) Warning Light on page 5-19.

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

Driving and Operating

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 on page 5-18
and Service Electric Parking Brake Light on page 5-19. There are also parking brake-related Driver Information Center (DIC) messages. See Brake System Messages on page 5-32. In case of insufficient electrical power, the EPB cannot be applied or released. Before leaving the vehicle, check the red parking brake status light to ensure that the parking brake is applied. EPB Apply To apply the EPB: 1. Be sure the vehicle is at a

complete stop.

2. Lift up the EPB switch

momentarily.

The red parking brake status light will flash and then stay on once the EPB is fully applied. If the red parking brake status light flashes continuously, then the EPB is only partially applied or there is a problem with the EPB. A DIC message will display. Release the EPB and try to apply it again. If the light does not come on, or keeps flashing, have the vehicle serviced. Do not drive the vehicle if the red parking brake status light is flashing. See your dealer. See Electric Parking Brake Light on page 5-18. 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 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.

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico- 6007198) - 2014 - CRC - 2/5/14

Black plate (37,1)

StabiliTrak activates when the vehicle senses a difference between the intended path and the direction the vehicle is actually traveling. StabiliTrak selectively applies braking pressure to any one of the vehicle wheel brakes to assist the driver in keeping the vehicle on the intended path. If cruise control is being used when TCS begins to limit wheel spin, the cruise control will automatically disengage. Cruise control may be reengaged when road conditions allow. See Cruise Control on page 9-47. Both systems come on automatically when the vehicle is started and begins to move. The systems may be heard or felt while they are operating or while performing diagnostic checks. This is normal and does not mean there is a problem with the vehicle.

It is recommended to leave both systems on for normal driving conditions, but it may be necessary to turn TCS off if the vehicle gets stuck in sand, mud, ice, or snow. See If the Vehicle Is Stuck on page 9-13 and “Turning the Systems Off and On” later in this section.

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.

Driving and Operating

9-37

If either system fails to turn on or to activate, a message displays in the Driver Information Center (DIC), and d comes on and stays on to indicate that the system is inactive and is not assisting the driver in maintaining control. The vehicle is safe to drive, but driving should be adjusted accordingly. If d comes on and stays on: 1. Stop the vehicle. 2. Turn the engine off and wait

15 seconds.

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

Automatic Transmissions

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

The Launch Control feature will initially limit engine speed as the driver rapidly applies the accelerator pedal to wide open throttle. Allow the engine rpm to stabilize. A smooth, quick release of the brake pedal, while maintaining the fully pressed accelerator pedal, will manage wheel slip. After the vehicle is launched, the system continues in Competitive Mode (except Z51 with Magnetic Selective Ride Control) or

Performance Traction Management (Z51 with Magnetic Selective Ride Control). Competitive Driving Mode, PTM, and Launch Control are systems designed for a closed course race track and not intended for use on public roads. The systems are not intended to compensate for lack of driver experience or familiarity with the race track.

Limited-Slip Differential (Except Z51) If equipped, the mechanical limited-slip differential can give more traction on snow, mud, ice, sand, or gravel. It works like a standard axle most of the time, but when traction is low, this feature allows the drive wheel with the most traction to move the vehicle.

Limited-Slip Differential (Z51 Only) If equipped, the Electronic Limited Slip Differential (ELSD) is automatically activated. ELSD actively monitors vehicle sensors and driver inputs to determine the amount of change for the conditions. With ELSD, the vehicle has: . Enhanced high-speed control.

Improved traction through corners, allowing more acceleration.

. More precise steering.

Increased vehicle agility. Integration with StabiliTrak.

If equipped with a manual transmission, the cruise control will remain active when the gears are shifted. The cruise is disengaged if the clutch is pressed for several seconds. If the Traction Control System (TCS) begins to limit wheel spin while you are using cruise control, the cruise control automatically disengages. See Traction Control/Electronic Stability Control on page 9-36. When road conditions allow for using safely again, the cruise control can be turned back on.

1 (On/Off): Press to turn cruise control on and off. A white indicator appears in the instrument cluster when cruise is turned on. RES/+ (Resume/Accelerate): Press briefly to make the vehicle resume to a previously set speed, or press and hold to accelerate. If cruise control is already active, use to increase vehicle speed. SET/– (Set/Coast): Press briefly to set the speed and activate cruise control. If cruise control is already active, use to decrease vehicle speed. * (Cancel): Press to disengage cruise control without erasing the set speed from memory.

Cruise Control With cruise control, a speed of about 40 km/h (25 mph) or more can be maintained without keeping your foot on the accelerator. Cruise control does not work at speeds below about 40 km/h (25 mph).

{ Warning

Cruise control can be dangerous where you cannot drive safely at a steady speed. Do not use the cruise control on winding roads or in heavy traffic. Cruise control can be dangerous on slippery roads. On such roads, fast changes in tire traction can cause excessive wheel slip, and you could lose control. Do not use cruise control on slippery roads.

If the brakes are applied, the cruise control disengages.

Driving and Operating

Use premium unleaded gasoline meeting ASTM specification D4814
with a posted octane rating of 91 or higher. If the octane is less than 91, damage to the engine may occur and may void the vehicle warranty. If heavy knocking is heard when using gasoline rated at 91 octane or higher, the engine needs service.

Use of Seasonal Fuels Use summer and winter fuels in the appropriate season. The fuels industry automatically modifies the fuel for the appropriate season. If fuel is left in the vehicle tank for long periods of time, driving or starting could be affected. Drive the vehicle until the fuel is at one-half tank or less, then refuel with the current seasonal fuel.

Prohibited Fuels Gasolines containing oxygenates such as ethers and ethanol, as well as reformulated gasolines, are available in some cities. If these gasolines comply with the previously described specification, then they are acceptable to use. However, E85 (85% ethanol) and other fuels containing more than 15% ethanol must be used only in FlexFuel vehicles.

{ Caution

Do not use fuel containing methanol. It can corrode metal parts in the fuel system and also damage plastic and rubber parts. That damage would not be covered under the vehicle warranty.

Some gasolines, mainly high octane racing gasolines, can contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT). Do not use gasolines and/or fuel additives with MMT as they can reduce spark plug life and affect emission control system performance. The malfunction indicator lamp may turn on. If this occurs, see your dealer for service.

Gasoline Specifications At a minimum, gasoline should meet ASTM specification D 4814. Some gasolines contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT). We recommend against the use of gasolines containing MMT. See “Prohibited Fuels" in Fuel on page 9-51.

California Fuel Requirements If the vehicle is certified to meet California Emissions Standards, it is designed to operate on fuels that meet California specifications. See the underhood emission control label. If this fuel is not available in states adopting California Emissions Standards, the vehicle will operate satisfactorily on fuels meeting federal specifications, but emission control system performance might be affected. The malfunction indicator lamp could turn on and the vehicle may not pass a smog-check test. See Malfunction Indicator Lamp on page 5-15. If this occurs, return to your authorized dealer for diagnosis. If it is determined that the condition is caused by the type of fuel used, repairs may not be covered by the vehicle warranty.

Fuels in Foreign Countries If planning to drive in countries outside the U.S. or Canada, the proper fuel might be hard to find. Check regional auto club or fuel retail brand websites for availability in the country where driving. Never use leaded gasoline, fuel containing methanol, manganese, or any other fuel not recommended. Costly repairs caused by use of improper fuel would not be covered by the vehicle warranty.

Fuel Additives To keep fuel systems clean, TOP TIER Detergent Gasoline is recommended. See Fuel on page 9-51. If TOP TIER Detergent Gasoline is not available, one bottle of Fuel System Treatment PLUS added to the fuel tank at every engine oil change, can help. Fuel System Treatment PLUS is the only

gasoline additive recommended by General Motors. It is available at your dealer.
