2015 Chevrolet VOLT Owners Manual

Air Vents Use the louvers on the air vents to change the direction of the airflow. Use the thumbwheels near each vent to open and close off the airflow.

Operation Tips . Keep all outlets open whenever

possible for best system performance.

. Keep the path under all seats

clear of objects to help circulate the air inside the vehicle more effectively.

. Use of non-GM approved hood deflectors can adversely affect the performance of the system.

. Do not attach any devices to the

air vent slats, this restricts airflow and may cause damage to the air vents.

Driving Information

Driving for Better Energy Efficiency Use the following tips to help maximize energy efficiency and range. In colder temperatures, while these efficiency tips will help, the electric vehicle driving range may be lower due to higher energy usage. Driving Style

Efficiency Gauge (Instrument Cluster) The ball indicator should be kept green and in the center of the gauge. Inefficient acceleration is indicated when the ball turns yellow and travels above the center of the gauge.

Aggressive braking is indicated when the ball turns yellow and travels below the center of the gauge.

Acceleration/Braking/Coasting Avoid unnecessary rapid accelerations and decelerations. Electric range is maximized at 80 km/h (50 mph) and below. Higher speeds use more energy and can significantly reduce electric range. Use cruise control when appropriate. Plan ahead for decelerations and coast whenever possible. For example, do not rush to traffic signals. Do not shift to N (Neutral) to coast. The vehicle recovers energy while coasting and braking in D (Drive) or L (Low).

Chevrolet VOLT Owner Manual (GMNA-Localizing-U.S./Canada-7695131) - 2015 - CRC - 9/15/14

Black plate (3,1)

Drive Mode and PRNDL Selection Use Normal Mode when possible. Sport Mode provides more responsive acceleration than Normal Mode but can reduce efficiency. Use Mountain Mode prior to climbing long, steep grades in mountainous areas. Be sure to engage Mountain Mode before starting to climb. Mountain Mode reduces electric range and power but may be needed to maintain speeds above 96 km/h (60 mph) when climbing grades of 5% or greater. Use Hold Mode on a trip where all or most of the electric charge will be depleted. Use Hold Mode mainly during highway or high speed driving to maximize both EV miles and fuel efficiency. Use L (Low) in heavy stop-and-go traffic or when traveling downhill. L (Low) requires less brake pedal

application and provides a controlled, efficient way to slow the vehicle down. Climate Setting Using the heat and air conditioning systems decreases the energy available for electric driving. Optimal energy efficiency is achieved with the heat, air conditioning, and fan turned off. Less energy is used at low fan speeds. When using the fan:

Fan Only is the most energy efficient climate setting as long as 0 is not selected.

. ECO is for moderate air conditioning and heater operation and is the next most energy efficient setting as long as 0 is not selected.

. Comfort provides the most

comfort but is the least energy efficient.

Driving and Operating

9-3

Use the auto heated seat feature instead of climate settings. Heating the seat uses less energy than heating the vehicle interior. Use remote start to heat or cool the interior when the vehicle is plugged in to maximize the electric range by utilizing electricity from the electrical outlet. Engine Assisted Heating operation, if equipped, can be personalized. In hot weather, avoid parking in direct sunlight or use sunshades inside the vehicle. Turn off the front and rear window defog/defrost when they are no longer needed. Avoid driving with the windows open at highway speeds. See Vehicle Personalization on page 5-50.

Driving and Operating

Vehicle Charging/Maintenance

Charging Keep the vehicle plugged in, even when fully charged, to keep the battery temperature ready for the next drive. This is important when outside temperatures are extremely hot or cold.

Maintenance Always keep the tires properly inflated and the vehicle properly aligned. The weight of excess cargo in the vehicle affects efficiency and range. Avoid carrying more than is needed. If fuel is not regularly used, consider keeping the fuel tank only one-third full. Excess fuel weight impacts efficiency and range. For fuel recommendations, see Fuel on page 9-52
Avoid unnecessary use of electrical accessories. Power used for functions other than propelling the vehicle will reduce EV range.

Using a rooftop carrier will reduce efficiency due to additional weight and drag.

Distracted Driving Distraction comes in many forms and can take your focus from the task of driving. Exercise good judgment and do not let other activities divert your attention away from the road. Many local governments have enacted laws regarding driver distraction. Become familiar with the local laws in your area. To avoid distracted driving, always keep your eyes on the road, hands on the wheel, and mind on the drive. . Do not use a phone in

demanding driving situations. Use a hands-free method to place or receive necessary phone calls.

. Watch the road. Do not read,

take notes, or look up information on phones or other electronic devices.

. Designate a front seat

passenger to handle potential distractions.

. Become familiar with vehicle

features before driving, such as programming favorite radio stations and adjusting climate control and seat settings. Program all trip information into any navigation device prior to driving.

. Wait until the vehicle is parked

to retrieve items that have fallen to the floor.

. Stop or park the vehicle to tend

to children.

. Keep pets in an appropriate

carrier or restraint.

. Avoid stressful conversations while driving, whether with a passenger or on a cell phone.

{ Warning

Taking your eyes off the road too long or too often could cause a crash resulting in injury or death. Focus your attention on driving.

Refer to the infotainment section for more information on using that system and the navigation system, if equipped, including pairing and using a cell phone.

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. . 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.

. Allow enough following distance

between you and the driver in front of you. Focus on the task of driving.

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

9-5

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

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

you and the vehicle in front of you.

. Avoid needless heavy braking. . Keep pace with traffic.

Chevrolet VOLT Owner Manual (GMNA-Localizing-U.S./Canada-7695131) - 2015 - CRC - 9/15/14

Black plate (6,1)

Steering in Emergencies

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

. Holding both sides of the

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

Off-Road Recovery

9-6

Driving and Operating

If propulsion is disabled 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 propulsion 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.

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. 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 5-48. 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.

Chevrolet VOLT Owner Manual (GMNA-Localizing-U.S./Canada-7695131) - 2015 - CRC - 9/15/14

Black plate (7,1)

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

Driving and Operating

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.

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.

9-8

Driving and Operating

{ 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.

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 10-40. Turn off cruise control.

Hill and Mountain Roads Driving on steep hills or through mountains is different than driving on flat or rolling terrain. See “Mountain Mode” under Driver Selected Operating Modes on page 9-22. 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 electric drive unit.

. Keep the vehicle in gear when going down steep or long hills.

Chevrolet VOLT Owner Manual (GMNA-Localizing-U.S./Canada-7695131) - 2015 - CRC - 9/15/14

Black plate (9,1)

{ Warning

Coasting downhill in N (Neutral) or with the vehicle turned off is dangerous. The brakes will have to do all the work of slowing down the vehicle and could become too hot. Hot brakes may not be able to slow the vehicle enough to maintain speed and control. You could crash. Always have the vehicle running and in gear (preferably LOW range) when going downhill. This will allow the electric drive unit to assist in slowing and maintaining speed.

. 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

9-9

If equipped, Traction Control should be turned on. See Traction Control/ Electronic Stability Control on page 9-32. The Antilock Brake System (ABS) 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. 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 the vehicle, especially any that is blocking the exhaust pipe.

. Check again from time to

time to be sure snow does not collect there.

. Open a window about 5 cm

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

. Fully open the air outlets on

or under the instrument panel.

. Adjust the climate control

system to a setting that circulates the air inside the

(Continued)

vehicle and set the fan speed to the highest setting. See “Climate Control Systems” in the Index. For more information about carbon monoxide, see Engine Exhaust on page 9-26.

To conserve energy, run the vehicle for only short periods as needed to warm the vehicle and then shut the vehicle 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, start the vehicle. The engine may start to charge the 12-volt battery. Turn off unnecessary accessories to conserve energy.

Black plate (11,1)

If the Vehicle Is Stuck Slowly and cautiously spin the wheels to free the vehicle when stuck in sand, mud, ice, or snow. The Traction Control System (TCS) must be turned off by pressing the TCS/ESC button. Traction control is not completely off, but will only engage if the maneuver can cause damage to the electric drive unit.

{ Warning

If the vehicle's tires spin at high speed, they can explode, and you or others could be injured. The vehicle can overheat, causing an engine compartment fire or other damage. Spin the wheels as little as possible and avoid going above 56 km/h (35 mph).

Rocking the Vehicle to Get it Out Turn the steering wheel left and right to clear the area around the front wheels. Shift back and forth between R (Reverse) and a forward gear, spinning the wheels as little as possible. The Traction Control System prevents the tires from spinning at high speeds. To prevent electric drive unit 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 electric drive unit 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 10-75.

Vehicle Load Limits It is very important to know how much weight the vehicle can carry. This weight is called the vehicle capacity weight and includes the weight of all occupants, cargo, and all nonfactory-installed options. Two labels on the vehicle show how much weight it was designed to 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 (Continued)

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). With the driver door open, the label is attached below the door lock post. The Tire and Loading Information label shows the number of occupant seating positions (1), and the maximum vehicle capacity weight (2) in kilograms and pounds. The Tire and Loading Information label also shows the tire 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 10-40 and Tire Pressure on page 10-47. There is also important loading information on the 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

weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage load capacity calculated in Step 4. If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Consult this manual to determine how this reduces the available cargo and luggage load capacity of your vehicle.”

Do not leave the vehicle when the propulsion system is running. If you have left the propulsion system 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 9-19.

Driving and Operating

9-19

If you have to leave the vehicle with the propulsion system on, 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 pulling it toward you. If you can, it means that the shift lever was not fully locked into P (Park). Torque Lock Torque lock is when the weight of the vehicle puts too much force on the parking pawl in the electric drive unit. This happens when parking on a hill and shifting the electric drive unit into P (Park) is not done properly and then it is difficult to shift out of P (Park). To prevent torque lock, set the parking brake and then shift into P (Park).

9-20

Driving and Operating

If torque lock does occur, your vehicle may need to be pushed uphill by another vehicle to relieve the parking pawl pressure, so you can shift out of P (Park).

Shifting out of Park To shift out of P (Park), the vehicle must be in ON/RUN, the brake pedal must be applied, and the charge cord must be unplugged. The vehicle has an electronic shift lock release system. The shift lock release is designed to: . Prevent the vehicle from turning

off unless the shift lever is in P (Park).

. Prevent moving the shift lever

out of P (Park), unless the vehicle is in ON/RUN, the brake pedal is applied, and the charge cord is unplugged.

Parking the vehicle in extreme cold for several days without the charge cord connected may cause the

electric drive unit to be locked in P (Park) until the propulsion system has warmed sufficiently. The shift lock is always functional except in the case of an uncharged or low charged 12-volt battery (less than 9 volts). If the vehicle has an uncharged 12-volt battery or a 12-volt battery with low voltage, try charging or jump starting the 12-volt battery. See Battery on page 10-23 or Jump Starting on page 10-69. If the console shift lever cannot be moved out of P (Park): 1. Apply and maintain the regular

brakes.

2. Turn the vehicle on using the POWER O button. See Power Button on page 9-15.

3. Let up on the shift lever and make sure the shift lever is pushed all the way into P (Park).

4. Press the shift lever button.

5. Move the shift lever into the

desired gear.

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

Electric Vehicle Operating Modes

System Operation This vehicle is an Extended Range Electric Vehicle (EREV). It uses an electric propulsion system to drive the vehicle at all times. Electricity is the vehicle's primary source of energy, while gasoline is the secondary source. The vehicle has two modes of operation: Electric and Extended Range. In both modes, the vehicle is propelled by its electric drive unit. It converts electrical energy into mechanical energy to drive the wheels. The vehicle's performance remains the same in either mode. See Driving for Better Energy Efficiency on page 9-2.

Electric Mode In Electric Mode, the vehicle does not use fuel or produce tailpipe emissions. During this primary

Driving and Operating

9-21

mode, the vehicle is powered by electrical energy stored in the high voltage battery. The vehicle can operate in this mode until the battery has reached a low charge. There are some conditions when the battery charge is high enough to provide Electric Mode operation, but the engine still runs. They are: . Cold ambient temperatures. . Hot or cold high voltage battery

temperatures. The hood being open or not completely closed and latched.

. Certain high voltage battery fault

conditions.

. Engine Maintenance Mode or

Fuel Maintenance Mode being run.

Extended Range Mode When the vehicle reaches the end of its electric range, it switches to Extended Range Mode (ERM). In this secondary mode, electricity is

produced by the fuel‐powered engine. This secondary source of electric power extends the vehicle range. Operation will continue in ERM until the vehicle can be plugged in to recharge the high voltage battery and restore Electric Mode. The high voltage battery will continue to provide some power and work together with the engine to provide peak performance when it is required, such as driving up a steep incline or for high acceleration maneuvers. The battery will not be charged nor will electric vehicle range be restored by the engine. In either Electric Mode or Extended Range Mode, when the hood is open, the engine will run without turning off if the vehicle is on. The high voltage battery is neither charged nor discharged when this occurs. In either Electric Mode or Extended Range Mode, if there is a high voltage battery fault, the engine may

Press the DRIVE MODE button to select Mountain Mode. If steep hill driving is expected, it is recommended to select Mountain Mode at least 20 minutes before driving on steep grades. This will allow the vehicle time to build a sufficient battery charge reserve. If Mountain Mode is not selected for these conditions, propulsion power may be reduced and the engine speed may increase. See Propulsion Power Messages on page 5-47. The engine may run when Mountain Mode is selected, depending on high voltage battery charge, to build reserve battery charge for uphill climbs. If Mountain Mode is entered with a sufficient battery charge reserve, the battery charge reserve will appear grayed out and any battery charge reserve still unused upon exiting Mountain Mode will return to normal appearance.

Mountain Mode

Mountain Mode should be selected at the beginning of a trip before climbing steep, uphill grades and when expecting to drive in very hilly or mountainous terrain. This mode maintains a reserve electrical charge of the high voltage battery to provide better grade climbing performance. While driving in Mountain Mode, the vehicle will have less responsive acceleration. Mountain Mode will not change normal vehicle braking performance for steep downhill grades. See Hill and Mountain Roads on page 9-8
and Electric Drive Unit on page 9-27.

Driving and Operating

Press the Drive Mode button again to return to Normal Mode and it becomes active after three seconds. The Mountain light comes on when Mountain Mode is selected. See Mountain Mode Light on page 5-21. Each time the vehicle is started, it will return to Normal Mode to maintain a smaller battery charge reserve for normal driving. Hold Mode

Hold Mode is only available when the vehicle is in Electric Mode. This mode places the remaining battery charge into a reserve for the driver to use as desired. Selecting this

mode transitions the vehicle to Extended Range Mode to maintain the battery charge reserve. Upon exiting Hold Mode, the reserved battery charge becomes available again and the vehicle returns to Electric Mode. If the transition is from Hold Mode directly to Mountain Mode, the electric range displayed adjusts for the Mountain Mode charge reserve. Hold Mode will not change normal vehicle acceleration or braking performance. Press the DRIVE MODE button to select Hold Mode. Press the DRIVE MODE button again to return to Normal Mode and it becomes active after three seconds. The Hold light comes on when Hold Mode is selected. See Hold Mode Light on page 5-21. Each time the vehicle is started, it will return to Normal Mode.

Out of Fuel/Engine Unavailable If the vehicle runs out of fuel, or the engine will not start due to a malfunction, the vehicle can continue to be driven in Electric Mode. The vehicle will have less responsive acceleration. DIC messages indicate reduced propulsion power, that the engine is not available, and the need for fuel or service. Once the vehicle is refueled, or the malfunction is corrected, the engine will start the next time the vehicle is turned on to perform a self test, and DIC messages will not be displayed. Once the engine starts successfully, normal operation will continue in either Electric or Extended Range Mode. The engine will stop running after the self test is completed, and based on the current mode of operation. See Fuel System Messages on page 5-45 and Service Vehicle Messages on page 5-48.

Maintenance Modes

Engine Maintenance Mode (EMM) EMM runs the engine to keep it in good working condition after approximately six weeks of no or very limited engine operation. EMM will force the engine to run, even if there is a charge to power the vehicle. When EMM is needed, the EMM Request screen appears on the center stack display at vehicle start.

EMM, a DIC message displays to show the EMM percentage complete. If No is selected, the EMM Request screen will appear when the vehicle is next started. The EMM request can be delayed for only one day. If the EMM request was delayed for one day, EMM will automatically start the engine at the next vehicle start. An EMM Notification screen will appear in the center stack display.

If Yes is selected, EMM will begin. The engine will run for a set amount of time without turning off. During

If the vehicle shuts off during EMM, it will restart the next time the vehicle is driven. A message displays to indicate that EMM is active.

If EMM is required and the fuel level is low, EMM may eventually empty the fuel tank if fuel is not added. This will result in reduced, or no power. An adequate fuel level must be maintained in the vehicle to keep it operational. See Propulsion Power Messages on page 5-47.

Fuel Maintenance Mode (FMM) FMM tracks average fuel age. Old fuel can cause engine problems. If low engine usage causes average fuel age to exceed approximately one year, FMM will run the engine to use up the old fuel. The engine will run until enough fresh fuel is added to bring the average fuel age into an acceptable range. Allowing more old

fuel to be used up by FMM and adding a larger amount of fresh fuel will maximize the length of time before another fuel maintenance mode is needed. During FMM the engine may turn on and off. When FMM is needed, the FMM Request screen appears on the center stack display at vehicle start.

If the FMM request was delayed for one day, FMM will start at the next vehicle start and display the FMM Notification screen on the center stack display. If FMM is required and the fuel level is low, FMM may eventually empty the fuel tank if fuel is not added. This will result in reduced, or no power. An adequate fuel level must be maintained in the vehicle to keep it operational. See Propulsion Power Messages on page 5-47.

If Yes is selected, FMM will begin. FMM will automatically continue at each vehicle start until fresh fuel is added. If No is selected, the FMM Request screen will appear when the vehicle is next started. The FMM request can be delayed for only one day.

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 engine is running in

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

. The exhaust smells or

sounds strange or different.

{ 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 propulsion system is running. If you have left the propulsion system 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 9-19.

Make sure the shift lever is fully in P (Park) before starting the propulsion system. The vehicle has an electric drive unit shift lock control system. The regular brake must be fully applied first and then the shift lever button pressed before

shifting from P (Park) when the vehicle is in ON/RUN. If you cannot shift out of P (Park), ease pressure on the shift lever, then push the shift lever all the way into P (Park) as you maintain brake application. Then press the shift lever button and move the shift lever into another gear. See Shifting out of Park on page 9-20. R (Reverse): Use this gear to back up.

{ Caution

Shifting to R (Reverse) while the vehicle is moving forward could damage the electric drive unit. 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 electric drive unit, see If the Vehicle Is Stuck on page 9-11.

In this position, the

N (Neutral): propulsion system does not connect with the wheels. D (Drive): This position is for normal driving. It provides the best fuel economy. If more power is needed for passing, and the vehicle is: . Going less than 56 km/h

(35 mph), push the accelerator pedal about halfway down.

. Going about 56 km/h (35 mph) or

more, push the accelerator all the way down.

{ Caution

If the vehicle seems to accelerate slowly or not respond when you go faster, and you continue to drive the vehicle that way, you could damage the electric drive unit. Have the vehicle serviced right away.

Chevrolet VOLT Owner Manual (GMNA-Localizing-U.S./Canada-7695131) - 2015 - CRC - 9/15/14

Black plate (29,1)

L (Low): This position reduces vehicle speed without using the brakes. Use L (Low) on very steep hills, in deep snow, in mud, or in stop-and-go traffic.

{ Caution

Spinning the tires or holding the vehicle in one place on a hill using only the accelerator pedal may damage the electric drive unit. The repair will not be covered by the vehicle warranty. If you are stuck, do not spin the tires. When stopping on a hill, use the brakes to hold the vehicle in place.

Brakes

Antilock Brake System (ABS) This vehicle has ABS, an advanced electronic braking system that helps prevent a braking skid. When propulsion is active and the vehicle begins to drive away, ABS checks itself. A momentary motor or clicking noise might be heard while this test is going on, and it might even be noticed that the brake pedal moves a little. This is normal.

If there is a problem with ABS, this warning light stays on. See Antilock Brake System (ABS) Warning Light on page 5-20.

Driving and Operating

9-29

If driving safely on a wet road and it becomes necessary to slam on the brakes and continue braking to avoid a sudden obstacle, a computer senses that the wheels are slowing down. If one of the wheels is about to stop rolling, the computer will separately work the brakes at each wheel. ABS can change the brake pressure to each wheel, as required, faster than any driver could. This can help the driver steer around the obstacle while braking hard. As the brakes are applied, the computer keeps receiving updates on wheel speed and controls braking pressure accordingly. Remember: ABS does not change the time needed to get a foot up to the brake pedal or always decrease stopping distance. If you get too close to the vehicle in front of you, there will not be enough time to apply the brakes if that vehicle

suddenly slows or stops. Always leave enough room up ahead to stop, even with ABS. Using ABS Do not pump the brakes. Just hold the brake pedal down firmly and let ABS work. You might hear the ABS pump or motor operating and feel the brake pedal pulsate, but this is normal. Braking in Emergencies ABS allows the driver to steer and brake at the same time. In many emergencies, steering can help more than even the very best braking.

Electric Parking Brake

The vehicle has an Electric Parking Brake (EPB). The switch is on the center stack. The EPB can always be activated, even if the vehicle is off. To prevent draining the 12-volt battery, avoid repeated cycles of the EPB system when the vehicle is off. The system has a red parking brake status light and an amber parking brake warning light. See Electric Parking Brake Light on page 5-20
and Service Electric Parking Brake Light on page 5-20. There are also

parking brake-related Driver Information Center (DIC) messages. See Brake System Messages on page 5-43. 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. Pull the EPB switch momentarily. The red parking brake status light
