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.

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.

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.

Black plate (4,1)

9-4

Driving and Operating

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.

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 Power Steering Fluid on page 10‑25. If power steering assist is lost because the engine stops or the power steering system is not functioning, the vehicle can be steered but may required increased effort. See your dealer if there is a problem.

If the vehicle is a hybrid, see the hybrid supplement for more information. 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.

. Holding both sides of the

steering wheel allows you to turn 180 degrees without removing a hand.

. Antilock Brake System (ABS) allows steering while braking.

GMC Savana Owner Manual - 2012 - 2nd - 11/11/11

Black plate (5,1)

Off-Road Recovery

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. 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.

Driving and Operating

9-5

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.

. 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.

GMC Savana Owner Manual - 2012 - 2nd - 11/11/11

Black plate (6,1)

9-6

Driving and Operating

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.

{ 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.

GMC Savana Owner Manual - 2012 - 2nd - 11/11/11

Black plate (7,1)

. Have good tires with proper

tread depth. See Tires on page 10‑50. Turn off cruise control.

Highway Hypnosis Always be alert and pay attention to your surroundings while driving. If you become tired or sleepy, find a safe place to park the vehicle and rest. Other driving tips include: . Keep the vehicle well ventilated. . Keep 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.

Driving and Operating

9-7

{ 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.

. 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).

GMC Savana Owner Manual - 2012 - 2nd - 11/11/11

Black plate (8,1)

9-8

Driving and Operating

. 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.

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 9‑33 improves vehicle stability during hard stops on a 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, if equipped, 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.

Driving and Operating

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 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 56 km/h (35 mph).

See Tire Chains on page 10‑71. 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 10‑89.

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/Tire label.

{ WARNING

Tire and Loading Information Label

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.

Label Example

A vehicle specific Tire and Loading Information label is attached to the 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 shows the number of occupant seating

positions (A), and the maximum vehicle capacity weight (B) in kilograms and pounds. The Tire and Loading Information label also shows the size of the original equipment tires (C) and the recommended cold tire inflation pressures (D). For more information on tires and inflation see Tires on page 10‑50 and Tire Pressure on page 10‑57. There is also important loading information on the vehicle Certification/Tire 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/Tire 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

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.

6.

If your vehicle will be towing a trailer, the load from your trailer will be transferred to your vehicle. Consult this manual to determine how this reduces the available cargo and luggage load capacity of your vehicle. See Trailer Towing on page 9‑50 for important information on towing a trailer, towing safety rules and trailering tips.

Certification/Tire Label

Refer to the vehicle tire and loading information label for specific information about the vehicle's capacity weight and seating positions. The combined weight of the driver, passengers, and cargo should never exceed the vehicle capacity weight.

A vehicle specific Certification/ Tire label is found on the rear edge of the driver door. The label shows the size of the vehicle's original tires and the inflation pressures needed to obtain the gross weight capacity of the vehicle. This is called

Gross Vehicle Weight Rating (GVWR). The GVWR includes the weight of the vehicle, all occupants, fuel, and cargo. The Certification/Tire label also tells you the maximum weights for the front and rear axles, called Gross Axle Weight Rating (GAWR). To find out the actual loads on the front and rear axles, you need to go to a weigh station and weigh the vehicle. Your dealer can help you with this. Be sure to spread out the load equally on both sides of the centerline. Never exceed the GVWR for the vehicle, or the GAWR for either the front or rear axle.

GMC Savana Owner Manual - 2012 - 2nd - 11/11/11

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: . Keep the vehicle speed at

88 km/h (55 mph) or less for the first 805 km (500 miles).

. 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.

. Do not tow a trailer during

break-in. See Trailer Towing on page 9‑50 for the trailer towing capabilities of the vehicle and more information.

Following break‐in, engine speed and load can be gradually increased.

Ignition Positions

The ignition switch has four different positions. To shift out of P (Park), the ignition must be in ON/RUN or ACC/ ACCESSORY and the regular brake pedal applied.

A (STOPPING THE ENGINE/ LOCK/OFF): When the vehicle is stopped, turn the ignition switch to LOCK/OFF to turn the engine off. Retained Accessory Power (RAP) will remain active. See Retained Accessory Power (RAP) on page 9‑21. This position locks the ignition and transmission. 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.

4. Set the parking brake. See

Parking Brake on page 9‑34.

{ 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. Notice: Using a tool to force the key to turn in the ignition could cause damage to the switch or break the key. Use the correct key, make sure it is all the way in, and turn it only with your hand. If the key cannot be turned by hand, see your dealer. B (ACC/ACCESSORY): This is the position in which you can operate things like the radio and the windshield wipers when the engine is off.

Driving and Operating

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 tone will sound when the driver door is opened, the ignition is in ACC/ACCESSORY or LOCK/OFF and the key is in the ignition.

Starting the Engine If the vehicle has a diesel engine, see the Duramax® diesel supplement for more information. To place the transmission in the proper gear: 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.

Starting Procedure 1. With your foot off the accelerator

pedal, turn the ignition key to START. When the engine starts, let go of the key. The idle speed will go down as your engine gets warm. 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 for many seconds, 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 5-10 seconds, especially in very cold weather (below −18°C or 0°F), it could be flooded with too much gasoline. Try pushing the accelerator pedal all the way to

the floor and holding it there as you hold the key in START for up to 15 seconds. Wait at least 15 seconds between each try, to allow the cranking motor to cool down. When the engine starts, let go of the key and accelerator. If the vehicle starts briefly but then stops again, do the same thing. This clears the extra gasoline from the engine. Do not race the engine immediately after starting it. Operate the engine and transmission gently until the oil warms up and lubricates all moving parts.

Notice: 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 9‑58.

Fast Idle System If the vehicle has this feature it is available only with cruise control. The manual fast idle switch is operated using the cruise control buttons located on the left hand side of the steering wheel. This system can be used to increase engine idle speed whenever the following conditions are met:

The park brake is set. The brake pedal is not pressed. The vehicle must not be moving and the accelerator must not be pressed.

To control the fast idle:

To enable the Fast Idle System, press and release the Cruise Control On/Off button and ensure that the switch LED is lit.

. Press and release the Cruise

Control Set switch. Engine speed will be held at approximately 1200 RPM.

. Pressing the Cruise Control Set

switch a second time.

. Pressing the accelerator greater than a quarter of the way down. Turning the ignition switch to the LOCK/OFF position.

Engine Heater If the vehicle has a diesel engine, see the Duramax diesel supplement for more information. The engine coolant heater can provide easier starting and better fuel economy during engine warm‐up in cold weather conditions at or below −18°C (0°F). Vehicles with an engine coolant heater should be plugged in at least four hours before starting. An internal thermostat in the plug-end of the cord may exist which will prevent engine coolant heater operation at temperatures above −18°C (0°F). To Use the Engine Coolant Heater 1. Turn off the engine. 2. Open the hood and unwrap the

electrical cord.

The cord for the engine coolant heater is located on the driver side of the engine compartment and is attached to the hose for the power steering reservoir.

3. Plug it into a normal, grounded

110-volt AC outlet.

{ WARNING Plugging the cord into an ungrounded outlet could cause an electrical shock. Also, the wrong kind of extension cord could overheat and cause a fire. You could be seriously injured. Plug the cord into a properly grounded three-prong 110-volt AC outlet. If the cord will not reach, use a heavy-duty three-prong extension cord rated for at least 15 amps.

4. Before starting the engine, be

sure to unplug and store the cord as it was before to keep it away from moving engine parts and prevent damage.

2. Move the shift lever into P (Park)

by pulling the shift lever toward you and moving it up as far as it will go.

3. Turn the ignition key to

LOCK/OFF.

4. Remove the key and take it with you. If you can leave the vehicle with the ignition key in your hand, the vehicle is in P (Park).

The length of time the heater should remain plugged in depends on several factors. Ask a dealer in the area where you will be parking the vehicle for the best advice on this.

Retained Accessory Power (RAP) These vehicle accessories can be used for up to 10 minutes after the engine is turned off: . Audio System . Power Windows (if equipped) These features will work when the ignition key is in ON/RUN or ACC/ ACCESSORY. Once the key is turned from ON/RUN to LOCK/OFF, power to the radio and power windows will continue to work 10 minutes or until the driver door is opened.

Shifting Into Park { WARNING

It can be dangerous to get out of the vehicle if the shift lever is not fully in P (Park) with the parking brake firmly set. The vehicle can roll. If you have left the engine running, the vehicle can move suddenly. You or others could be injured. To be sure the vehicle will not move, even when you are on fairly level ground, use the steps that follow. If you are pulling a trailer, see Driving Characteristics and Towing Tips on page 9‑46.

Leaving the Vehicle With the Engine Running

{ WARNING

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

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 move the shift lever into P (Park), hold the regular brake pedal down. Then, 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 If you are parking on a hill and you do not shift the vehicle 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 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 parking pawl in the transmission, so you can pull the shift lever out of P (Park).

Shifting out of Park The vehicle has an automatic transmission shift lock control system. You have to fully apply the brakes before you can shift from P (Park) when the ignition is in ON/ RUN or ACC/ACCESSORY. See Automatic Transmission (Six Speed) on page 9‑25 or Automatic Transmission (Four Speed) on page 9‑28.

being removed unless the shift lever is in P (Park).

. Prevent movement of the shift

lever out of P (Park), unless the ignition is in ON/RUN or ACC/ ACCESSORY and the regular brake pedal is applied.

The shift lock control system is always functional except in the case of a dead battery or low voltage (less than 9 V) battery. If the vehicle has an uncharged battery or a battery with low voltage, try charging or jump starting the battery. See Jump Starting on page 10‑84 for more information.

To shift out of P (Park) use the following: 1. Apply the brake pedal. 2. Turn the ignition to ACC/

ACCESSORY or ON/RUN. 3. Move the shift lever to the

desired position.

If you still are unable to shift out of P (Park): 1. Ease the pressure on the shift

lever.

2. While holding down the brake

pedal, push the shift lever all the way into P (Park).

3. Move the shift lever to the

desired position.

If you are still having a problem shifting, have the vehicle serviced.
