6 (Floor): Air is directed to the floor outlets, with some of the air directed to the windshield and side window outlets. In this mode, the system automatically selects outside air. - (Defog): This mode clears the windshield of fog or moisture. Air is directed equally to the windshield and the floor outlets. When defog is selected, the system turns off recirculation and runs the air conditioning compressor unless the outside temperature is below 4°C (40°F). 0 (Defrost): This mode clears the windshield of fog or frost more quickly. Air is directed to the windshield with some air to the side window vents and the floor vents. When defrost is selected, the system automatically forces outside air into the vehicle. The air conditioning compressor will run automatically in this setting, unless the outside temperature is below 4°C (40°F).
# (Air Conditioning): Press to turn the air conditioning system on or off. An indicator light comes on to show that it is on. The air conditioning can be selected in any mode as long as the fan is on and the outside temperature is above freezing. A flashing indicator light indicates that the air conditioning compressor is currently not available. On hot days, open the windows to let hot inside air escape; then close them. This helps to reduce the time it takes for the vehicle to cool down. It also helps the system to operate more efficiently. For quick cool down on hot days, do the following: 1. Select the H mode. 2. Press the # button. 3. Select the coolest temperature
for both zones.
4. Select the highest 9 speed.

5. When the coolest temperature is
selected in the A/C mode, the system automatically goes into the recirculation mode to improve cooling.
Using these settings together for long periods of time may cause the air inside the vehicle to become too dry. To prevent this from happening, after the air inside the vehicle has cooled, turn the recirculation mode off. The air conditioning system removes moisture from the air, so a small amount of water may drip under the vehicle while idling or after turning off the engine. This is normal. % (Outside Air): Press to turn on outside air. An indicator light comes on to show that it is on. Outside air will circulate throughout the vehicle. / (Recirculation): Press to turn on the recirculation mode. An indicator light comes on to show that it is on.

This mode helps to quickly heat or cool the air inside the vehicle once the temperature inside the vehicle is equal to or better than the outside temperature. It can be used to prevent outside air and odors from entering the vehicle. The recirculation mode is not available in outside air, floor, defog, or defrost modes. If the button is selected while in these modes, the indicator flashes three times. Rear Window Defogger The rear window defogger uses a warming grid to remove fog from the rear window. 1 (Rear Window Defogger): The rear window defogger turns off automatically after it has been activated for 10 minutes. It can be turned off manually, by pressing the button again or by turning the ignition to the LOCK/OFF position.
The rear window defogger can be turned on again for additional window clearing. The length of defogger operation will increase if the vehicle is being driven. For vehicles with heated outside rearview mirrors, the mirrors heat to help clear fog or frost from the surface of the mirror when the rear window defog button is pressed. See Power Mirrors on page 2‑14. Do not drive the vehicle until all the windows are clear. Notice: Do not use anything sharp on the inside of the rear window. If you do, you could cut or damage the warming grid, and the repairs would not be covered by the vehicle warranty. Do not attach a temporary vehicle license, tape, a decal, or anything similar to the defogger grid.
Air Vents Use the thumbwheel located below or to the side of the outlet, to change the direction of the air flow. Operation Tips . Clear away any ice, snow,
or leaves from the air inlets at the base of the windshield that may block the flow of air into the vehicle.
. Use of non-GM approved hood deflectors may adversely affect the performance of the system.
. Keep the path under the front seats clear of objects to help circulate the air inside the vehicle more effectively.

If the airflow seems low when the fan is at the highest setting, the passenger compartment air filter, if equipped, may need to replaced. For more information, see Passenger Compartment Air Filter on page 8‑5 and Maintenance Schedule on page 11‑3. If fogging reoccurs while in vent or bi-level modes with mild temperature throughout the vehicle, turn on the air conditioner to reduce windshield fogging.
Maintenance
Passenger Compartment Air Filter The vehicle has a passenger compartment particulate air filter. It is located in the engine compartment, below the air inlet grille on the passenger side. The filter traps most of the pollen from air entering the climate control system. It needs to be changed periodically to ensure system performance. For information on how often to change the passenger compartment air filter, see Maintenance Schedule on page 11‑3.
Climate Controls

Driving Information
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, including pairing and using a cell phone. If equipped, refer to the navigation manual for information on that system, including pairing and using a cell phone.
Chevrolet Impala Owner Manual - 2012
Black plate (3,1)
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 3‑10. . 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.
Control of a Vehicle Braking, steering, and accelerating are important factors in helping to control a vehicle while driving.
Driving and Operating
9-3
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 Impala Owner Manual - 2012
Black plate (4,1)
9-4
Driving and Operating
If the engine ever stops while the vehicle is being driven, brake normally but do not pump the brakes. Doing so could make the pedal harder to push down. If the engine stops, there will 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
Hydraulic Power Steering Your vehicle has hydraulic power steering. It may require maintenance. See Power Steering Fluid on page 10‑17. 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.
Curve Tips
Off-Road Recovery
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.
. 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.
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.
Chevrolet Impala Owner Manual - 2012
Black plate (5,1)
2. Turn the steering wheel about one-eighth of a turn, until the right front tire contacts the pavement edge.
3. Then 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 quickly steer the way you want the vehicle to go. The vehicle may straighten out. Be ready for a second skid if it occurs.
Driving and Operating
9-5
. 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.
Chevrolet Impala Owner Manual - 2012
Black plate (6,1)
9-6
Driving and Operating
Driving on Wet Roads Rain and wet roads can reduce vehicle traction and affect your ability to stop and accelerate. Always drive slower in these types of driving conditions and avoid driving through large puddles and deep‐standing or flowing water.
{ WARNING
Wet brakes can cause crashes. They might not work as well in a quick stop and could cause pulling to one side. You could lose control of the vehicle. After driving through a large puddle of water or a car/vehicle wash, lightly apply the brake pedal until the brakes work normally.
(Continued)
WARNING (Continued)
Flowing or rushing water creates strong forces. Driving through flowing water could cause the vehicle to be carried away. If this happens, you and other vehicle occupants could drown. Do not ignore police warnings and be very cautious about trying to drive through flowing water.
Hydroplaning Hydroplaning is dangerous. Water can build up under the vehicle's tires so they actually ride on the water. This can happen if the road is wet enough and you are going fast enough. When the vehicle is hydroplaning, it has little or no contact with the road. There is no hard and fast rule about hydroplaning. The best advice is to slow down when the road is wet.
Other Rainy Weather Tips Besides slowing down, other wet weather driving tips include: . Allow extra following distance. . Pass with caution. . Keep windshield wiping
equipment in good shape.
. Keep the windshield washer fluid
reservoir filled.
. Have good tires with proper
tread depth. See Tires on page 10‑33. Turn off cruise control.
Highway Hypnosis Always be alert and pay attention to your surroundings while driving. If you become tired or sleepy, find a safe place to park the vehicle and rest.
Chevrolet Impala Owner Manual - 2012
Black plate (7,1)
Other driving tips include: . Keep the vehicle well ventilated. . Keep the interior temperature cool.
. Keep your eyes moving — scan the road ahead and to the sides.
. Check the rearview mirror and
vehicle instruments often.
Hill and Mountain Roads Driving on steep hills or through mountains is different than driving on flat or rolling terrain. Tips for driving in these conditions include: . Keep the vehicle serviced and in
good shape.
. Check all fluid levels and brakes,
tires, cooling system, and transmission.
. Shift to a lower gear when going
down steep or long hills.
{ WARNING
If you do not shift down, the brakes could get so hot that they would not work well. You would then have poor braking or even none going down a hill. You could crash. Shift down to let the engine assist the brakes on a steep downhill slope.
{ WARNING
Coasting downhill in N (Neutral) or with the ignition off is dangerous. The brakes will have to do all the work of slowing down and they could get so hot that they would not work well. You would then have poor braking or even none going down a hill. You could crash. Always have the engine running and the vehicle in gear when going downhill.
Driving and Operating
9-7
. 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.
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.
Chevrolet Impala Owner Manual - 2012
Black plate (8,1)
9-8
Driving and Operating
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. Try not to break the fragile traction. If you accelerate too fast, the drive wheels will spin and polish the surface under the tires even more. The Antilock Brake System (ABS) on page 9‑26 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 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
(Continued)
WARNING (Continued)
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.
. Fully open the air outlets on
or under the instrument panel.
(Continued)
Chevrolet Impala Owner Manual - 2012
Black plate (9,1)
WARNING (Continued)
. Adjust the climate control
system to a setting that circulates the air inside the vehicle and set the fan speed to the highest setting. See Climate Control System in the Index.
For more information about carbon monoxide, see Engine Exhaust on page 9‑21. Snow can trap exhaust gases under your vehicle. This can cause deadly CO (Carbon Monoxide) gas to get inside. CO could overcome you and kill you. You cannot see it or smell it, so you might not know it is in your vehicle. Clear away snow from around the base of your vehicle, especially any that is blocking the exhaust.
Run the engine for short periods only as needed to keep warm, but be careful. To save fuel, run the engine for only short periods as needed to warm the vehicle and then shut the engine off and close the window most of the way to save heat. Repeat this until help arrives but only when you feel really uncomfortable from the cold. Moving about to keep warm also helps. If it takes some time for help to arrive, now and then when you run the engine, push the accelerator pedal slightly so the engine runs faster than the idle speed. This keeps the battery charged to restart the vehicle and to signal for help with the headlamps. Do this as little as possible to save fuel.
Driving and Operating
9-9
If the Vehicle Is Stuck Slowly and cautiously spin the wheels to free the vehicle when stuck in sand, mud, ice, or snow. If the vehicle has a traction system, it can often help to free a stuck vehicle. Refer to the vehicle's traction system in the Index. If stuck too severely for the traction system to free the vehicle, turn the traction system off and use the rocking method.
{ WARNING
If the vehicle's tires spin at high speed, they can explode, and you or others could be injured. The vehicle can overheat, causing an engine compartment fire or other damage. Spin the wheels as little as possible and avoid going above 55 km/h (35 mph).
See Tire Chains on page 10‑52.

Driving and Operating
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 or stability system. Shift back and forth between R (Reverse) and a 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. See Towing the Vehicle on page 10‑65.
Vehicle Load Limits It is very important to know how much weight your vehicle can carry. Two labels on your vehicle show how much weight it may properly carry, the Tire and Loading Information label and the Vehicle Certification label.
{ WARNING
Do not load the vehicle any heavier than the Gross Vehicle Weight Rating (GVWR), or either the maximum front or rear Gross Axle Weight Rating (GAWR). This can cause systems to break and change the way the vehicle handles. This could cause loss of control and a crash. Overloading can also shorten the life of the vehicle.
Tire and Loading Information Label
Label Example
A vehicle-specific Tire and Loading Information label is attached to the vehicle's center pillar (B-pillar). With the driver door open, you will find the label attached below the door lock post (striker). The Tire and Loading Information label lists the number of occupant seating

9-11
positions (A), and the maximum vehicle capacity weight (B) in kilograms and pounds. The vehicle capacity weight includes the weight of all occupants, cargo, and all nonfactory‐installed options. The Tire and Loading Information label also lists the tire size of the original equipment tires (C) and the recommended cold tire inflation pressures (D). For more information on tires and inflation, see Tires on page 10‑33 and Tire Pressure on page 10‑40. 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 there will be five 150 lb passengers in your vehicle,
the amount of available cargo
and luggage load capacity
is 650 lbs (1400 − 750
(5 x 150) = 650 lbs).
5. Determine the combined
6.
weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage load capacity calculated in Step³4. If your vehicle will be towing a trailer, the load from your trailer will be transferred to your vehicle. Consult this manual to determine how this reduces the available cargo and luggage load capacity for your vehicle.
If your vehicle can tow a trailer,

New Vehicle Break-In Notice: The vehicle does not need an elaborate break-in. But it will perform better in the long run if you follow these guidelines:
. Do not drive at any one constant speed, fast or slow, for the first 805 km (500 miles). Do not make full-throttle starts. Avoid downshifting to brake or slow the vehicle.
. Avoid making hard stops for the first 322 km (200 miles) or so. During this time the new brake linings are not yet broken in. Hard stops with new linings can mean premature wear and earlier replacement. Follow this breaking-in guideline every time you get new brake linings.

transmission. This is the only
position in which the ignition key
can be inserted or removed.
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), and turn the ignition to LOCK/OFF. On vehicles with an automatic transmission, the shift lever must be in P (Park) to turn the ignition switch to the LOCK/OFF position.

{ 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, turn the ignition to ACC/ ACCESSORY. The steering can bind with the wheels turned off center. If this happens, move the steering wheel from left to right while turning the key to ACC/ACCESSORY. If this doesn't work, then the vehicle needs service. B (ACC/ACCESSORY): This is the position in which you can operate the radio and windshield wipers
while the engine is off. To use ACC/ ACCESSORY, turn the key clockwise. C (ON/RUN): This position can be used to operate the electrical accessories and to display some instrument panel cluster warning and indicator lights. This position can also be used for service and diagnostics, and to verify the proper operation of the malfunction indicator lamp as may be required for emission inspection purposes. The switch stays in this position when the engine is running. If you leave the key in the ACC/ ACCESSORY or ON/RUN position with the engine off, the battery could be drained. You may not be able to start the vehicle if the battery is allowed to drain for an extended period of time. D (START): This is the position that starts the engine. When the engine starts, release the key. The ignition switch returns to ON/RUN for driving.
A warning chime will sound and the Driver Information Center (DIC) will display DRIVER DOOR OPEN when the driver door is opened, the ignition is in ACC/ACCESSORY or LOCK/OFF, and the key is in the ignition. See Door Ajar Messages on page 5‑28 for more information.
Starting the Engine Move the shift lever to P (Park) or N (Neutral). The engine will not start in any other position. To restart the engine when the vehicle is already moving, use N (Neutral) only. Notice: 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. Starting Procedure 1. With your foot off the accelerator pedal, turn the ignition to START. When the engine starts, let go of the key. The idle speed will slow down as the engine warms. Do

not race the engine immediately after starting it. Operate the engine and transmission gently to allow the oil to warm up and lubricate all moving parts. The vehicle has a Computer-Controlled Cranking System. This feature assists in starting the engine and protects components. If the ignition key is turned to the START position, and then released when the engine begins cranking, the engine will continue cranking for a few seconds or until the vehicle starts. If the engine does not start and the key is held in START, cranking will be stopped after 15 seconds to prevent cranking motor damage. To prevent gear damage, this system also prevents cranking if the engine is already running. Engine cranking can be stopped by turning the ignition switch to the ACC/ACCESSORY or LOCK/OFF position.
When the Low Fuel warning lamp is on and the FUEL LEVEL LOW message is displayed in the Driver Information Center (DIC), the Computer‐Controlled Cranking System is disabled to prevent possible vehicle component damage. When this happens, hold the ignition switch in the START position to continue engine cranking.
Notice: Cranking the engine for long periods of time, by returning the key 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. 2.
If the engine does not start after five to 10 seconds, especially in very cold weather (below −18°C or 0°F), it could be flooded with too much gasoline. Try pushing the accelerator pedal all the way to the floor and holding it there as you hold the key in START

If you have to leave the vehicle with the engine running, be sure your vehicle is in P (Park) and the parking brake is firmly set before you leave it. See Parking Brake on page 9‑27 for more information. Torque Lock Torque lock is when the weight of the vehicle puts too much force on the parking pawl in the transmission. This happens when parking on a hill and shifting the transmission 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). To find out how, see “Shifting Into Park” in this section. 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).

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. Also, use N (Neutral) when the vehicle is being towed.
{ 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.
Notice: 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 you need more power for passing, and you are: . 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.
Notice: If the vehicle seems to accelerate slowly or not shift gears when you go faster, and you continue to drive the vehicle that way, you could damage the transmission. Have the vehicle serviced right away. You can drive in L (Low) when you are driving less than 56 km/h (35 mph) and D (Drive) for higher speeds until then. Downshifting the transmission in slippery road conditions could result in skidding, see "Skidding" under Loss of Control on page 9‑5. L (Low): This position gives you access to gear ranges. This provides more engine braking but lower fuel economy than D (Drive). You can use it on very steep hills, or in deep snow or mud. See the following text on Manual Mode.

The vehicle has an electronic shift position indicator within the instrument cluster. When using the ERS mode a number will display next to the L, indicating the current range that has been selected. To use this feature: 1. Move the shift lever to L (Low). 2. Press the + (Plus) or − (Minus)
button located on the left side of the steering wheel, to increase or decrease the gear range available.
When you shift from D (Drive) to L (Low), the transmission will shift to a pre-determined lower gear range.
The highest gear available for this pre-determined range is displayed next to the L in the DIC. The number displayed in the DIC is the highest gear that the transmission will be allowed to operate in. All gears below that number are available. For example, when 4 (Fourth) is shown next to the L, 1 (First) through 4 (Fourth) gears are automatically shifted by the vehicle. The transmission will not shift into 5 (Fifth) until the + (Plus) button is used or you shift back into D (Drive). While in L (Low), the transmission will prevent shifting to a lower gear range if the engine speed is too high.

Brakes
Antilock Brake System (ABS) This vehicle has the Antilock Brake System (ABS), an advanced electronic braking system that helps prevent a braking skid. When the engine is started 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 5‑19.
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 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.

Parking Brake
The parking brake is located to the left of the brake pedal, near the driver door. To set the parking brake, hold the brake pedal down, then push down the parking brake pedal.
To release the parking brake, hold the brake pedal down and push the parking brake pedal. When you lift your foot off the parking brake pedal, the pedal will follow it to the released position. A warning chime will sound and a brake warning light located on the instrument panel cluster will come on, if the parking brake is set, the ignition is on, and the vehicle speed is greater than 8 km/h (5 mph). Notice: 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. If you are towing a trailer and parking on any hill, see Driving Characteristics and Towing Tips on page 9‑39.

Ride Control Systems
Traction Control System (TCS) The vehicle may have a Traction Control System (TCS) that limits wheel spin. This is especially useful in slippery road conditions. The system operates only if it senses that one or both of the front wheels are spinning or beginning to lose traction. When this happens, the system reduces engine power and may also upshift the transmission and apply the front brakes to limit wheel spin.
This light will flash when the TCS is limiting wheel spin.

Driving and Operating
The system may be heard or felt while it is working, but this is normal. 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 9‑30. The TCS operates in all transmission shift lever positions. But the system can upshift the transmission only as high as the shift lever position chosen, so use the lower gears only when necessary. See Automatic Transmission on page 9‑22.
When the system is on, this warning light comes on and stays on if there is a problem. A SERVICE TRACTION CONTROL message also appears on the DIC. When this warning light is on, the system will not limit wheel spin. Adjust your driving accordingly. See Ride Control System Messages on page 5‑31 for more information. To limit wheel spin, especially in slippery road conditions, TCS should always be left on. But the system can be turned off if needed. Turn the system off if the vehicle gets stuck in sand, mud, or snow and rocking the vehicle is required. See If the Vehicle Is Stuck on page 9‑9 for more information.
To turn the system on or off, press the ESC OFF button located on the instrument panel. When the system is turned off, the TRACTION CONTROL OFF message appears on the DIC. If the traction control system is limiting wheel spin when the button is pressed to turn the system off,
