2015 Chevrolet Corvette Owners Manual

Drunk Driving Death and injury associated with drinking and driving is a global tragedy.

{ 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.

Driving and Operating

9-3

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

Steering

Electric Power Steering The vehicle has electric power steering. It does not have power steering fluid. Regular maintenance is not required. If power steering assist is lost due to a system malfunction, the vehicle can be steered, but may require increased effort. See your dealer if there is a problem. If the steering wheel is turned until it reaches the end of its travel and is held against that position for an extended period of time, power steering assist may be reduced. If the steering assist is used for an extended period of time, power assist may be reduced.

. Holding both sides of the

steering wheel allows you to turn 180 degrees without removing a hand. The Antilock Brake System (ABS) allows steering while braking.

Off-Road Recovery

9-4

Driving and Operating

Normal use of the power steering assist should return when the system cools down. See specific vehicle steering messages under Service Vehicle Messages on page 5-42. See your dealer if there is a problem. Curve Tips

Take curves at a reasonable speed.

. Reduce speed before entering a

curve.

. Maintain a reasonable steady

speed through the curve.

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

Steering in Emergencies

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

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

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

3. Turn the steering wheel to go

straight down the roadway.

Loss of Control

Skidding There are three types of skids that correspond to the vehicle's three control systems: . Braking Skid — wheels are not

rolling.

. Steering or Cornering Skid —

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

. Acceleration Skid — too much

throttle causes the driving wheels to spin.

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

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

. Slow down and adjust your driving according to weather conditions. Stopping distance can be longer and vehicle control can be affected when traction is reduced by water, snow, ice, gravel, or other

material on the road. Learn to recognize warning clues — such as enough water, ice, or packed snow on the road to make a mirrored surface — and slow down when you have any doubt. Try to avoid sudden steering, acceleration, or braking, including reducing vehicle speed by shifting to a lower gear. Any sudden changes could cause the tires to slide.

Remember: Antilock brakes help avoid only the braking skid.

Track Events and Competitive Driving Participating in track events or other competitive driving without following the instructions provided may affect the vehicle warranty. See the warranty manual before using the vehicle for racing or other competitive driving. Refer to Competitive Driving Mode on page 9-43.

Be sure to follow all service procedures before driving the vehicle at track events or competitively.

Engine Oil

{ Caution

If the vehicle is used for track events and competitive driving, the engine may use more oil than it would with normal use. Low oil levels can damage the engine. Check the oil level often and maintain the proper level. See Engine Oil on page 10-12.

{ Caution

Not changing the engine oil to 15W-50 may cause engine damage. Engine oil must be changed to 15W-50 synthetic. See Capacities and Specifications on page 12-2.

Driving and Operating

Z51 and Z06 Only: Check the oil level often during track events and competitive driving and keep the level at or near 0.5 L (0.5 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. Except Z51 and Z06: Additional oil fill above the upper mark on the dipstick is not recommended for track events or other competitive driving. 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. 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.

Brake Fluid Replace existing brake fluid with a qualified high performance brake fluid from a sealed container. Brake fluid with a dry boiling point >279°C (534°F) is qualified. If high performance brake fluid is used, replace it with GM approved brake fluid before driving on public roads. If high performance brake fluid is in the vehicle and the age of the brake fluid is over a month old or unknown, replace the brake fluid before track events and competitive driving. Do not use silicone or DOT-5 brake fluids.

Load Limit Z51 Only: Limit vehicle load to the driver only, with no other cargo. Inflate tires to 180 kPa (26 psi) and drive at a maximum speed of 280 km/h (174 mph). Z06 Only: Limit vehicle load to the driver only, with no other cargo. Inflate tires to 180 kPa (26 psi) and drive at a maximum speed of 296 km/h (184 mph).

Wheel Alignment

{ Caution

Using these wheel alignment settings may cause excessive tire wear. Only use these wheel alignment settings for racing or competitive driving. Excessive tire wear is not covered under the vehicle warranty.

If the vehicle is equipped with the Z51 package or is a Z06, the racing and competitive driving wheel alignment settings should be set as follows: Alignment should only be done by adjusting the lower control arm cam bolts and by removing a maximum of one washer between the upper control arms and frame. Alignment values are targets, see your dealer for tolerances.

Rear Axle Fluid

{ Caution

During a first time track or racing event, high rear axle temperatures can occur. Damage could be caused to the rear axle and would not be covered by the vehicle warranty. Do not drive as long or as fast the first time the vehicle is driven on the track or raced.

The rear axle fluid temperatures may be higher than when driving in severe conditions. Drain and refill with new fluid after the first racing or

competitive driving event, and then after every 24 hours of racing or competitive driving. See Recommended Fluids and Lubricants on page 11-12.

General Information If reduced performance is experienced during track events or competitive driving, turning off the A/C will help to improve engine performance. Maintain a mixture of 40% DEX-COOL coolant and 60% clean, drinkable water to optimize engine performance. The front license plate bracket or aero panel should be removed for track events and competitive driving to improve engine performance. Rotor Cooling Ring The following installation procedure is for Z51, and only if the vehicle is equipped with front dual cast brake rotors along with the supplied brake cooling ring kit. See your dealer for information.

Driving and Operating

9-7

If the vehicle is a Z51 and equipped with a one piece brake rotor a cooling ring is not required. { Caution

Do not leave rotor cooling rings installed after a track event, as this can cause corrosion with long-term use. Rotor cooling rings are for track use only. Track driving without the rotor cooling rings may result in brake pedal fade.

Installation: 1. Remove the front wheels. 2. Cut three 150 mm (6 in) lengths of safety wire specified to T304
Stainless Steel, 0.041 in nominal diameter, not included.

3. Form each into a U shape with a

20 mm (0.75 in) flat area in the center of the wire.

4. Place the rotor ring in the gap between the rotor brake plate and rotor hat, with the holes on each side of the rotor spoke on the outboard side of the rotor.

5. Place the U-shaped wire through

the holes in the rotor cooling ring.

6. Bring the ends of the wire tight around the corresponding rotor spoke.

7. Twist the safety wire into six to eight twists per 2.54 cm (1 in).

8. Bend the twisted wire so it is

flush with the inside of the rotor ring to prevent contact with the caliper or brake hoses.

9. Verify that the rotor rings and safety wire do not contact any other components.

10. Reinstall the wheel using the

specific wheel nut torque. See Capacities and Specifications on page 12-2.

If additional brake cooling is required, the grille mesh in the lower corners of the front grille in front of the brake duct can be removed. This is not reversible, and a replacement grille will not be covered by the vehicle warranty. If this is done, it is recommended that the gap between the fascia and the cooling duct be taped over. Brake Burnishing New brake pads must be burnished before racing or other competitive driving.

{ Caution

Performing the brake burnish procedure on a base brake system can result in brake damage.

{ Caution

The new vehicle break-in period should be completed before performing the brake burnish procedure, otherwise damage may occur to the powertrain/ engine. See New Vehicle Break-In on page 9-18.

{ Caution

Brake pedal fade will occur during any track burnish procedure and can cause brake pedal travel and (Continued)

force to increase. This could extend stopping distance until the brakes are fully burnished.

When this procedure is performed as instructed, it will not damage the brakes. The brake pads will smoke and produce an odor. The braking force and pedal travel may increase. After the procedure, the brake pads may appear white at the rotor contact. Perform this procedure only on dry pavement, in a safe manner, and in compliance with all local and state ordinances/laws regarding motor vehicle operation.

Brake Burnish Procedure (Z51 and Z06 without Z07 Performance Package) 1. Apply the brakes 25 times

starting at 100 km/h (60 mph) to 50 km/h (30 mph) while decelerating at 0.4 g. This is a

medium brake application. Drive for at least 1 km (0.6 mi) between applying the brakes. This first step may be skipped if there are more than 320 km (200 mi) on the brake pads. 2. Repeatedly apply the brakes

from 100 km/h (60 mph) to 25 km/h (15 mph) while decelerating at 0.8 g. This is a hard brake application, without activating the Antilock Brake System (ABS). Drive for at least 1 km (0.6 mi) between stops. Repeat until the brake pedal travel starts to increase. Depending on conditions, this should take no longer than 25
brake applications.

3. Cool down: Drive at 100 km/h

(60 mph) for approximately 15 km (10 mi) without using the brakes.

4. Apply the brakes 25 times from 100 km/h (60 mph) to 50 km/h (30 mph) while decelerating at 0.4 g. This is a medium brake

application. Drive for at least 1 km (0.6 mi) between applications.

Street High Performance Brake Burnishing Procedure (Z06 with Z07 Performance Package) 1. From a stop, accelerate as rapidly as possible without activating traction control to a speed of 100 km/h (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 – 50

times. This should take about 10 minutes.

4. After completing the 50 stops,

cool the brakes by driving for km (5 mi) at 100 km/h (60 mph)

As with all high performance brake systems, some amount of brake squeal is normal.

Driving and Operating

Racing/Track Brake Burnishing Procedure (Z06 with Z07
Performance Package) This procedure should only be run on a track and only on dry pavement.

{ Caution

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, not too

aggressively.

2. Laps 2 and 3 should be

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

3. Drive Lap 4 near 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.

Z07 Performance Package The Z07 Performance Package has an installed Stage 2 Aero Package, which consists of a front splitter with short end caps, rocker panel extensions, and a rear spoiler. Stage 3 Aero components are delivered but not installed on the vehicle. These are intended to be installed for track use only. The components include:

Front splitter tall end caps that replace the front splitter short end caps.

. A center transparent wicker bill

for the rear spoiler.

{ Warning

Changing the following track settings could reduce tire traction and could cause a crash. Do not change the track settings

The track settings for the Z07
Performance Package with the Stage 3 Aero Package are:

The front splitter tall end caps installed. The center transparent wicker bill installed all the way up on the rear spoiler. The Driver Mode Selector in Track Mode.

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

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

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. 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.

Driving and Operating

9-11

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 10-46.

Turn off cruise control.

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

Using the brakes to slow the vehicle on a long downhill slope can cause brake overheating, can reduce brake performance, and could result in a loss of braking. Shift the transmission to a lower gear to let the engine assist the brakes on a steep downhill slope.

Driving and Operating

{ Warning

Winter Driving

Coasting downhill in N (Neutral) or with the ignition off is dangerous. This can cause overheating of the brakes and loss of steering. Always have the engine running and the vehicle in gear.

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

. Be alert on top of hills;

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

. Pay attention to special road

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

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. Traction Control should be turned on. See Traction Control/Electronic Stability Control on page 9-37. The Antilock Brake System (ABS) improves vehicle stability during hard stops on slippery roads, but

apply the brakes sooner than when on dry pavement. See Antilock Brake System (ABS) on page 9-34. 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 Roadside Assistance. See Roadside Assistance Program on page 13-5. 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. 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.

(Continued)

Warning (Continued)

. Fully open the air outlets on

or under the instrument panel.

. Adjust the climate control

system to a setting that circulates the air inside the vehicle and set the fan speed to the highest setting. See “Climate Control Systems.”

For more information about carbon monoxide, see Engine Exhaust on page 9-26.

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. See Traction Control/Electronic Stability Control on page 9-37.

{ Warning

If the vehicle's tires spin at high speed, they can explode, and you or others could be injured. The

Warning (Continued)

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).

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 on page 10-82.

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

Do not load the vehicle any heavier than the Gross Vehicle Weight Rating

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 door open, you will find the label attached below the door latch. This label shows the number of occupant seating positions (1), and the maximum vehicle capacity weight (2) in kilograms and pounds.

Driving and Operating

9-15

The Tire and Loading Information label also shows the size of the original equipment tires (3) and the recommended cold tire inflation pressures (4). For more information on tires and inflation see Tires on page 10-46 and Tire Pressure on page 10-55. 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.)

A vehicle-specific Certification label is attached to the rear edge of the driver door. It tells you the gross weight capacity of your vehicle, called the Gross Vehicle Weight Rating (GVWR). The GVWR includes the weight of the vehicle, all occupants, fuel and cargo. Never exceed the

GVWR for your vehicle, or the Gross Axle Weight Rating (GAWR) for either the front or rear axle. Do not load your vehicle with more weight than it was designed to carry. See “Steps for Determining Correct Load Limit” earlier in this section.

{ 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.

{ Caution

Overloading the vehicle may cause damage. Repairs would not be covered by the vehicle warranty. Do not overload the vehicle.

If you put things inside your vehicle — like suitcases, tools, packages or anything else — they will go as fast as the vehicle goes. If you have to stop or turn quickly, or if there is a crash, they will keep going.

{ Warning

Things you put inside your vehicle can strike and injure people in a sudden stop or turn, or in a crash.

(Continued)

Warning (Continued)

. Put things in the rear area

of your vehicle. Try to spread the weight evenly.

. Never stack heavier

things, like suitcases, inside the vehicle so that some of them are above the tops of the seats.

. Do not leave an

unsecured child restraint in your vehicle.

. When you carry something

inside the vehicle, secure it whenever you can.

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 for the first 322 km (200 mi).

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

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

abrupt stops.

{ Warning

The exposed edges of carbon fiber parts can be sharp when damaged. You or others could be injured. Use caution when washing the vehicle, coming in contact with damaged carbon fiber parts, or removing these parts. See your dealer for replacement.

Ignition Positions

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

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

. Avoid downshifting to brake or

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

. Do not let the engine labor.

Never lug the engine. 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 mi): . Do not participate in track

events, sport driving schools, or similar activities during the first 2 414 km (1,500 mi).

. 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 mi).

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.

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 on page 2-3. 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) on page 9-23.

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 on page 5-44. 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) on page 9-23. 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 LOCK/OFF.

4. Set the parking brake. See

Electric Parking Brake on page 9-35.

{ 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 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 on page 9-21. 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.

Driving and Operating

9-21

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.

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 fully pressed.

{ Caution

If you add electrical parts or accessories, you could change the way the engine operates. Any resulting damage would not be covered by the vehicle warranty. See Add-On Electrical Equipment on page 9-57.

{ Caution

Do not try to shift to P (Park) if the vehicle is moving. If you do, you could damage the transmission. Shift to P (Park) only when the vehicle is stopped.

The RKE transmitter must be inside the vehicle for the ignition to work. Cell phone chargers can interfere with the operation of the Keyless Access system. Battery chargers should not be plugged in when starting or turning off the engine.

To start the vehicle: 1. For vehicles with an automatic transmission, press the brake pedal, then press the ENGINE START/STOP button on the instrument panel. For vehicles with a manual transmission, press the clutch pedal first, then press the ENGINE START/ STOP button. If there is no RKE transmitter in the vehicle or if there is something causing interference with it, the DIC will display a message. See Key and Lock Messages on page 5-38. 2. When the engine begins

cranking, let go of the button and the engine cranks automatically until it starts. If the battery in the RKE transmitter is weak, the DIC will display a message. The vehicle can still be driven. See “Starting the Vehicle with a Low Transmitter Battery” under Remote Keyless Entry (RKE) System Operation on page 2-3.

If the remote transmitter battery is dead, insert it into the steering column transmitter pocket to enable engine starting. See “NO REMOTE KEY WAS DETECTED PLACE KEY IN TRANSMITTER POCKET THEN START YOUR VEHICLE” under Key and Lock Messages on page 5-38.

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.

Stopping the Engine If the vehicle has an automatic transmission, move the shift lever to P (Park) and press and hold the

ENGINE START/STOP button on the instrument panel, until the engine shuts off. If the shift lever is not in P (Park), the engine shuts off and the vehicle goes into the accessory mode. The DIC displays SHIFT TO PARK. Once the shift lever is moved to P (Park), the vehicle turns off. If the vehicle has a manual transmission, move the shift lever to R (Reverse) and set the parking brake after turning off the engine by pressing and holding the ENGINE START/STOP button. If the RKE transmitter is not detected inside the vehicle when it is turned to off, the DIC displays a message. See Key and Lock Messages on page 5-38.

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 (Continued)

Warning (Continued)

move the shift lever to P (Park). See Shifting Into Park on page 9-23.

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). 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 10-79. To shift out of P (Park): 1. Apply the brake pedal. 2. Release the parking brake. See

Electric Parking Brake on page 9-35.

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.

transmission using the paddle shift controls. See Manual Mode on page 9-28.

Manual Mode

Manual Paddle Shift

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

Black plate (29,1)

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 5-29. 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. The Manual Paddle Shift system can be deactivated by moving the shift lever from M (Manual Mode) back to D (Drive).

Driving and Operating

9-29

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 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 vehicles 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 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.
