Power Windows

{ WARNING:

Leaving children in a vehicle with the keys is dangerous for many reasons. Children or others could be badly injured or even killed. They could operate the power windows or other controls or even make the vehicle move. The windows will function and they could be seriously injured or killed if caught in the path of a closing window. Do not leave keys in a vehicle with children. When there are children in the rear seat use the window lockout button to prevent unintentional operation of the windows.

3-20

The power window switches are located on the driver door.

In addition, each door has a switch for its own window. The front power window switch operates with two positions for both up and down movement and the rear power window switch operates with one position for up and two positions for down movement. Press the switch to the first position to lower the window to the desired level. Pull the switch up to raise the window. The vehicle has Retained Accessory Power (RAP) that allows you to use the power windows once the ignition has been turned off. For more information, see Retained Accessory Power (RAP) on page 3‑29.

Theft-Deterrent Systems This vehicle has theft-deterrent features, however, they do not make it impossible to steal. Content Theft-Deterrent Your vehicle may have a content theft-deterrent alarm system.

This is the security light.

To arm the theft-deterrent system:

1. Open the door. 2. Lock the door with the Remote Keyless Entry

(RKE) transmitter or the power door lock switch. The security light will come on to inform the driver the system is arming. If a door is open when the doors are locked, the security light will flash. If the delayed locking feature is turned on, the theft‐deterrent system will not start the arming process until the last door is closed and the delay timer has expired. See Delayed Locking on page 3‑11 .

3. Close all doors. The security light should go off after about 30 seconds. The alarm is not armed until the security light goes off.

If a locked driver door is opened without using the RKE transmitter, a ten second pre-alarm will occur. The horn will chirp and the lights will flash. If the key is not placed in the ignition and turned to START or the door is not unlocked by pressing the unlock button on the RKE transmitter during the ten second pre-alarm, the alarm will go off. Your vehicle's headlamps will flash and the horn will sound for about 30 seconds, then will turn off to save the battery power.

3-23

Chevrolet Tahoe/Suburban Owner Manual - 2010

Black plate (24,1)

The theft-deterrent system will not activate if the doors are locked with the vehicle's key or the manual door lock. It activates only if you use the power door lock switch with the door open or the RKE transmitter. You should also remember that you can start your vehicle with the correct ignition key if the alarm has been set off. To avoid setting off the alarm by accident:

If you do not want to activate the theft-deterrent system, the vehicle should be locked with the door key after the doors are closed.

. Always unlock the doors with the RKE transmitter.

Unlocking a door any other way will set off the alarm if it is armed.

If you set off the alarm by accident, press unlock on the RKE transmitter or place the key in the ignition and turn it to START to turn off the alarm. The alarm will not stop if you try to unlock a door any other way.

Testing the Alarm To test the alarm:

1. From inside the vehicle, lower the driver's window

and open the driver's door.

2. Activate the system by locking the doors with the

power door lock switch while the door is open, or with the RKE transmitter.

3. Get out of the vehicle, close the door and wait for

the security light to go out.

4. Then reach in through the window, unlock the door with the manual door lock and open the door. This should set off the alarm.

While the alarm is set, the power door unlock switch will not work. If the alarm does not sound when it should but the headlamps flash, check to see if the horn works. The horn fuse may be blown. To replace the fuse, see Fuses and Circuit Breakers on page 6‑118. If the alarm does not sound or the headlamps do not flash, the vehicle should be serviced by your dealer.

PASS-Key® III+ Electronic Immobilizer See Radio Frequency Statement on page 8‑19 for information regarding Part 15 of the Federal Communications Commission (FCC) rules and Industry Canada Standards RSS-210/220/310. PASS-Key® III+ Electronic Immobilizer Operation Your vehicle has PASS-Key® III+ (Personalized Automotive Security System) theft-deterrent system. PASS-Key® III+ is a passive theft-deterrent system. The system is automatically armed when the key is removed from the ignition. The system is automatically disarmed when the key is turned to ON/RUN, ACC/ACCESSORY or START from the LOCK/OFF position. You do not have to manually arm or disarm the system. The security light will come on if there is a problem with arming or disarming the theft-deterrent system.

When the PASS-Key® III+ system senses that someone is using the wrong key, it prevents the vehicle from starting. Anyone using a trial-and-error method to start the vehicle will be discouraged because of the high number of electrical key codes. If the engine does not start and the security light on the instrument panel cluster comes on when trying to start the vehicle, there may be a problem with your theft-deterrent system. Turn the ignition off and try again. If the engine still does not start, and the key appears to be undamaged, try another ignition key. At this time, you may also want to check the fuse, see Fuses and Circuit Breakers on page 6‑118. If the engine still does not start with the other key, your vehicle needs service. If your vehicle does start, the first key may be faulty. See your dealer who can service the PASS-Key® III+ to have a new key made. In an emergency, contact Roadside Assistance.

It is possible for the PASS-Key® III+ decoder to learn the transponder value of a new or replacement key. Up to 10 keys may be programmed for the vehicle. The following procedure is for programming additional keys only. If all the currently programmed keys are lost or do not operate, you must see your dealer or a locksmith who can service PASS-Key® III+ to have keys made and programmed to the system. See your dealer or a locksmith who can service PASS-Key® III+ to get a new key blank that is cut exactly as the ignition key that operates the system. To program the new additional key:

1. Verify that the new key has a 1 stamped on it. 2.

Insert the original, already programmed, key in the ignition and start the engine. If the engine will not start, see your dealer for service.

3. After the engine has started, turn the key to LOCK/

4.

OFF, and remove the key. Insert the new key to be programmed and turn it to the ON/RUN position within five seconds of turning the ignition to the LOCK/OFF position in Step 3. The security light will turn off once the key has been programmed.

5. Repeat Steps 1 through 4 if additional keys are to

be programmed.

If you lose or damage your PASS-Key® III+ key, see your dealer or a locksmith who can service PASS-Key® III+ to have a new key made. Do not leave the key or device that disarms or deactivates the theft deterrent system in the vehicle.

Starting and Operating Your Vehicle

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 your speed at 55 mph (88 km/h) or less

for the first 500 miles (805 km).

. Do not drive at any one constant speed, fast

or slow, for the first 500 miles (805 km). Do not make full-throttle starts. Avoid downshifting to brake or slow the vehicle.

. Avoid making hard stops for the first

200 miles (322 km) 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

Towing a Trailer on page 5‑50 for the trailer towing capabilities of the vehicle and more information.

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

A (LOCK/OFF): This position locks the ignition. It also locks the transmission on automatic transmission vehicles. The key can be removed in LOCK/OFF. On vehicles with an automatic transmission, the shift lever must be in P (Park) to turn the ignition switch to LOCK/OFF. The steering can bind with the wheels turned off center. If this happens, move the steering wheel from right to left while turning the key to ACC/ACCESSORY. If this doesn't work, then the vehicle needs service. 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 position lets things like the radio and the windshield wipers operate while the engine is off. Use this position if the vehicle must be pushed or towed.

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 must be applied.

3-28

Chevrolet Tahoe/Suburban Owner Manual - 2010

Black plate (29,1)

C (ON/RUN): This position can be used to operate the electrical accessories and to display some instrument panel cluster warning and indicator lights. The switch stays in this position when the engine is running. The transmission is also unlocked in this position on automatic transmission vehicles. 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.

Retained Accessory Power (RAP) The following vehicle accessories can be used for up to 10 minutes after the engine is turned off:

. Audio System . Power Windows . OnStar® System (if equipped) . Sunroof (if equipped)

These features work when the key is in ON/RUN or ACC/ACCESSORY. Once the key is turned from ON/ RUN to LOCK/OFF, the windows and sunroof continue to work up to 10 minutes until any door is opened. The radio continues to work for up to 10 minutes or until the driver door is opened.

Starting the Engine If the vehicle is a Two-mode Hybrid, see the Two-mode Hybrid manual for more information. 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 are 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 key to START. When the engine starts, let go of the key. The idle speed will go down as the 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

3-30

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.

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 0°F or −18°C), 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 a maximum of 15 seconds. Wait at least 15 seconds between each try, to allow the cranking motor to cool down.

Chevrolet Tahoe/Suburban Owner Manual - 2010

Black plate (31,1)

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: The engine is designed to work with the electronics in the vehicle. If you add electrical parts or accessories, you could change the way the engine operates. Before adding electrical equipment, check with your dealer. If you do not, the engine might not perform properly. Any resulting damage would not be covered by the vehicle warranty. Adjustable Throttle and Brake Pedal On vehicles with this feature, you can change the position of the throttle and brake pedals. No adjustment to the pedals can be made when the vehicle is in R (Reverse) or while using the cruise control.

The switch used to adjust the pedals is located on the instrument panel below the climate control system.

Press the arrow at the bottom of the switch to move the pedals closer to your body. Press the arrow at the top of the switch to move the pedals away from your body. Before you start driving, fully press the brake pedal to confirm the adjustment is right for you. While driving, make only small adjustments. The vehicle may have a memory function which lets pedal settings be saved and recalled. See Memory Seat, Mirrors, and Pedals on page 2‑10 for more information.

Engine Coolant Heater 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 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 is secured to the Engine Compartment Fuse Block with a clip. Carefully remove the wire tie which secures the electrical cord. Do not cut the electrical cord.

3. Plug the cord 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. If you do not, it could be damaged.

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.

Automatic Transmission Operation If the vehicle is a Two-mode Hybrid, see the Two-mode Hybrid manual for more information. If the vehicle is has an automatic transmission, it has an electronic shift position indicator within the instrument panel cluster. This display comes on when the ignition key is turned to the ON/RUN position. There are several different positions for the shift lever.

Active Fuel Management™ Vehicles with V8 engines may have Active Fuel Management™. This system allows the engine to operate on either all or half of its cylinders, depending on the driving conditions. When less power is required, such as cruising at a constant vehicle speed, the system will operate in the half cylinder mode, allowing the vehicle to achieve better fuel economy. When greater power demands are required, such as accelerating from a stop, passing, or merging onto a freeway, the system will maintain full-cylinder operation. If the vehicle has an Active Fuel Management™ indicator, see DIC Operation and Displays (With DIC Buttons) on page 4‑48 or DIC Operation and Displays (Without DIC Buttons) on page 4‑55 for more information on using this display .

{ WARNING:

It is dangerous to get out of the vehicle if the shift lever is not fully in P (Park) with the parking brake firmly set. The vehicle can roll. Do not leave the vehicle when the engine is running unless you have to. If you have left the engine running, the vehicle can move suddenly. You or others could be injured. To be sure the vehicle will not move, even when you are on fairly level ground, always set the parking brake and move the shift lever to P (Park). See Shifting Into Park on page 3‑49 . If you are pulling a trailer, see Towing a Trailer on page 5‑50.

Heavy Duty 6-Speed Automatic Transmission Shown

(Light Duty Similar)

See “Range Selection Mode” later in this section. P (Park): This position locks the rear wheels. It is the best position to use when starting the engine because the vehicle cannot move easily. When parked on a hill, especially when the vehicle has a heavy load, you might notice an increase in the effort to shift out of P (Park). See Torque Lock (Automatic Transmission) under Shifting Into Park on page 3‑49 for more information.

{ WARNING:

If the vehicle has a four-wheel drive transfer case with a N (Neutral) position, and the transfer case is in N (Neutral), the vehicle will be free to roll — even if the shift lever is in P (Park). Be sure the transfer case is in a drive gear, Two-Wheel Drive High or Four-Wheel Drive High or Four-Wheel Drive Low — not in N (Neutral). See Shifting Into Park on page 3‑49 . Always set the parking brake.

R (Reverse): Use this gear to back up. Notice: Shifting to R (Reverse) while the vehicle is moving forward could damage the transmission. The repairs would not be covered by the vehicle warranty. Shift to R (Reverse) only after the vehicle is stopped. To rock the vehicle back and forth to get out of snow, ice, or sand without damaging the transmission, see If Your Vehicle is Stuck in Sand, Mud, Ice, or Snow on page 5‑31 .

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.

3-35

Chevrolet Tahoe/Suburban Owner Manual - 2010

Black plate (36,1)

If the shift stabilization feature determines that a current vehicle speed cannot be maintained, the transmission does not upshift and instead holds the current gear. In some cases, this could appear to be a delayed shift, however the transmission is operating normally. The vehicle's transmission uses adaptive shift controls. Adaptive shift controls continually compares key shift parameters to pre-programmed ideal shifts stored in the transmissions computer. The transmission constantly makes adjustments to improve vehicle performance according to how the vehicle is being used, such as with a heavy load or when the temperature changes. During this adaptive shift control process, shifting might feel different as the transmission determines the best settings. When temperatures are very cold, the Hydra-Matic® 6-Speed transmission's gear shifting could be delayed providing more stable shifts until the engine warms up. Shifts could be more noticeable with a cold transmission. This difference in shifting is normal.

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 about 35 mph (55 km/h), push the

accelerator pedal about halfway down.

. Going about 35 mph (55 km/h) or more, push the

accelerator all the way down. By doing this, the vehicle shifts down to the next gear and has more power.

D (Drive) can be used when towing a trailer, carrying a heavy load, driving on steep hills, or for off-road driving. You might want to shift the transmission to a lower gear selection if the transmission shifts too often. Downshifting the transmission in slippery road conditions could result in skidding. See Skidding under Loss of Control on page 5‑11. The vehicle has a shift stabilization feature that adjusts the transmission shifting to the current driving conditions in order to reduce rapid upshifts and downshifts. This shift stabilization feature is designed to determine, before making an upshift, if the engine is able to maintain vehicle speed by analyzing things such as vehicle speed, throttle position, and vehicle load.

Chevrolet Tahoe/Suburban Owner Manual - 2010

Black plate (37,1)

M (Manual Mode): This position is available on vehicles with the Hydra-Matic® 6-Speed transmission. It lets drivers select the range of gears appropriate for current driving conditions. If the vehicle has this feature, see Range Select Mode (Hydra-Matic® 6-Speed transmission) later in this section. 3 (Third): This position is also used for normal driving. It reduces vehicle speed more than D (Drive) without using the brakes. You might choose 3 (Third) instead of D (Drive) when driving on hilly, winding roads, when towing a trailer, so there is less shifting between gears and when going down a steep hill. 2 (Second): This position reduces vehicle speed even more than 3 (Third) without using the brakes. You can use 2 (Second) on hills. It can help control vehicle speed as you go down steep mountain roads, but then you would also want to use the brakes off and on. If you manually select 2 (Second) in an automatic transmission, the transmission will start in second gear. You can use this feature for reducing the speed of the rear wheels when you are trying to start the vehicle from a stop on slippery road surfaces.

1 (First): For the Hydra-Matic® 4-Speed transmission this position reduces vehicle speed even more than 2 (Second) without using the brakes. You can use it on very steep hills, or in deep snow or mud. If the shift lever is put in 1 (First) while the vehicle is moving forward, the transmission does not shift into first gear until the vehicle is going slowly enough. For a Hydra-Matic® 6-Speed transmission, this position reduces vehicle speed without using the brakes. You can use it for major/severe downgrades and off-road driving where the vehicle would otherwise accelerate due to steepness of grade. When you shift to 1 (First) it provides the lowest gear appropriate to the vehicle's current road speed and continues to downshift as the vehicle slows, eventually downshifting to 1 (First) gear. Notice: Spinning the tires or holding the vehicle in one place on a hill using only the accelerator pedal may damage the transmission. 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.

To use this feature, do the following:

1. Move the shift lever to M (Manual Mode). 2. Press the plus/minus buttons, located on the

steering column shift lever, to select the desired range of gears for the current driving conditions.

When M (Manual Mode) is selected a number displays next to the M, indicating the current gear. This number is the highest gear that can be used. However, the vehicle can automatically shift to lower gears as it adjusts to driving conditions. This means that all gears below that number are available. When 5 (Fifth) is selected, 1 (First) through 5 (Fifth) gears are automatically shifted by the vehicle, but 6 (Sixth) cannot be used until the plus/minus button located on the steering column lever is used to change to the gear. Grade Braking is not available when Range Selection Mode is active. See Tow/Haul Mode on page 3‑39.

Range Selection Mode (Hydra-Matic® 6-Speed Transmission)

Base trim shown (uplevel similar)

The vehicle may have a Range Selection Mode. The Range Selection Mode helps control the vehicle's transmission and vehicle speed while driving down hill or towing a trailer by letting you select a desired range of gears.

3-38

Chevrolet Tahoe/Suburban Owner Manual - 2010

Black plate (39,1)

While using Range Selection Mode, cruise control and the Tow/Haul mode can be used. Notice: Spinning the tires or holding the vehicle in one place on a hill using only the accelerator pedal may damage the transmission. 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. Low Traction Mode If the vehicle has the Hydra-Matic® 6-Speed Automatic Transmission, it has a Low Traction Mode that assists in vehicle acceleration when road conditions are slippery, such as with ice or snow. While the vehicle is at a stop, select the second gear range using Range Selection Mode. This will limit torque to the wheels after it detects wheel slip, preventing the tires from spinning.

Tow/Haul Mode

The vehicle has a Tow/Haul mode. The selector button is located on the end of the column shift lever. You can use this feature to assist when towing or hauling a heavy load or if there is a need to charge a battery installed in a trailer. See Towing a Trailer on page 5‑50
for more information.

3-39

Chevrolet Tahoe/Suburban Owner Manual - 2010

Black plate (40,1)

When Tow/Haul mode is selected the Tow/Haul indicator light will come on.

The Tow/Haul mode works with the Autoride® feature, if the vehicle has this, to enhance the ride when trailering or with a loaded vehicle. See Autoride® on page 5‑50 . Grade Braking (Hydra-Matic® 6-Speed Automatic Transmission) The Grade Braking shift modes can be activated by pressing the button on the end of the shift control lever. While in Range Selection Mode , Grade Braking is deactivated allowing the driver to select a desired range of gears.

Grade Braking is only active while the Tow/Haul Mode is selected and you are not in the Range Selection Mode. See “Tow/Haul Mode listed previously and Automatic Transmission Operation on page 3‑33 for more information on the Range Selection Mode. Grade Braking assists in maintaining desired vehicle speeds when driving on downhill grades by automatically implementing a shift schedule that utilizes the engine and transmission to slow the vehicle. This reduces wear on the braking system and increases control of the vehicle. Grade Braking monitors vehicle speed, acceleration, engine torque and brake pedal usage. Using this information, it detects when the truck is on a downhill grade and the driver desires to slow the vehicle by pressing the brake. Also see Towing a Trailer on page 5‑50 for more information.

Cruise Grade Braking (Hydra-Matic® 6-Speed Automatic Transmission) Cruise Grade Braking assists when driving on a downhill grade. It maintains vehicle speed by automatically implementing a shift schedule that uses the engine and the transmission to slow the vehicle. Cruise Grade Braking operates while Cruise Control is engaged in Tow/Haul mode to assist in maintaining vehicle speed under loaded vehicle conditions. It utilizes vehicle acceleration and deviation from desired speed to determine the correct gear for the operating condition. If vehicle speed is above the desired speed the transmission will downshift to slow the vehicle. If vehicle speed is near or below desired speed the trans will upshift, allowing vehicle speed to increase. While in the Range Select Mode (RSM) mode, Cruise Grade Braking is not available. See Automatic Transmission Operation on page 3‑33.

Four-Wheel Drive (Two Speed Automatic Transfer Case) If the vehicle has four-wheel drive, you can send the engine's driving power to all four wheels for extra traction. Read the following before using four-wheel drive. Notice: Driving on clean, dry pavement in Four-Wheel Drive High or Four-Wheel Drive Low for an extended period of time may cause premature wear on the vehicle's powertrain. Do not drive on clean, dry pavement in Four-Wheel Drive High or Four-Wheel Drive Low for extended periods of time. While driving on clean dry pavement and during tight turns, you may experience a vibration in the steering system. The vehicle has StabiliTrak®. Shifting into Four-Wheel-Drive Low will turn Traction Control and StabiliTrak® off. See StabiliTrak® System on page 5‑6.

Automatic Transfer Case

The transfer case knob is located to the left of the instrument panel cluster.

Use this dial to shift into and out of four-wheel drive. You can choose among five driving settings: Indicator lights in the switches show you which setting you are in. The indicator lights will come on briefly when you turn on the ignition and the last chosen setting will stay on. If the lights do not come on, you should take the vehicle to your dealer for service. An indicator light will flash while shifting. It will stay on when the shift is completed. If for some reason the transfer case cannot make a requested shift, it will return to the last chosen setting.

3-42

2 m (Two-Wheel Drive High): This setting is used for driving in most street and highway situations. The front axle is not engaged in two-wheel drive. This setting also provides the best fuel economy. AUTO (Automatic Four-Wheel Drive): This setting is ideal for use when road surface traction conditions are variable. When driving your vehicle in AUTO, the front axle is engaged, but the vehicle's power is primarily sent to the rear wheels. When the vehicle's software determines a need for more traction, the system will transfer more power to the front wheels. Driving in this mode results in slightly lower fuel economy than Two-Wheel Drive High. 4 m (Four-Wheel Drive High): Use the four-wheel high position when you need extra traction, such as on snowy or icy roads or in most off-road situations. This setting also engages your front axle to help drive the vehicle. This is the best setting to use when plowing snow. 4 n (Four-Wheel Drive Low) : This setting also engages the front axle and delivers extra torque. You may never need this setting. It sends maximum power to all four wheels. You might choose Four-Wheel Drive Low if you are driving off-road in deep sand, deep mud, deep snow, and while climbing or descending steep hills.

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. If you have four-wheel drive and the transfer case is in N (Neutral), the vehicle will be free to roll, even if the shift lever is in P (Park). So be sure the transfer case is in a drive gear — not in N (Neutral). 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 unless you have to.

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. 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 your transmission into P (Park) properly, the weight of the vehicle may put too much force on the parking pawl in the transmission. You may find it difficult to pull the shift lever out of P (Park). This is called torque lock. To prevent torque lock, set the parking brake and then shift into P (Park) properly before you leave the driver seat. To find out how, see Shifting Into Park on page 3‑49. 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, then you will be able to pull the shift lever out of P (Park).

Object Detection Systems

Ultrasonic Rear Parking Assist (URPA) For vehicles with the Ultrasonic Rear Parking Assist (URPA) system, it operates at speeds less than 8 km/h (5 mph), and assists the driver with parking and avoiding objects while in R (Reverse). The sensors on the rear bumper are used to detect the distance to an object up to 2.5 m (8 ft) behind the vehicle, and at least 25.4 cm (10 in) off the ground.

{ WARNING:

The Ultrasonic Rear Parking Assist (URPA) system does not replace driver vision. It cannot detect: . Objects that are below the bumper,

underneath the vehicle, or too close or far from the vehicle

. Children, pedestrians, bicyclists, or pets.

(Continued)

WARNING: (Continued)

If you do not use proper care before and while backing, vehicle damage, injury, or death could occur. Even with URPA, always check behind the vehicle before backing up. While backing, be sure to look for objects and check the vehicle's mirrors.

How the System Works URPA comes on automatically when the shift lever is moved into R (Reverse). A single tone sounds to indicate the system is working. URPA operates only at speeds less than 5 mph (8 km/h). An obstacle is indicated by audible beeps. The interval between the beeps becomes shorter as the vehicle gets closer to the obstacle. When the distance is less than 30 cm (12 in) the beeps are continuous. To be detected, objects must be at least 25.4 cm (10 in) off the ground and below liftgate level. Objects must also be within 2.5 m (8 ft) from the rear bumper. This distance may be less during warmer or humid weather.

Side Blind Zone Alert (SBZA) The vehicle may have a Side Blind Zone Alert (SBZA) system. Read this entire section before using the system.

Before making a lane change, always check the SBZA display, check the outside and rearview mirrors, look over your shoulder for vehicles and hazards, and use the turn signal.

{ WARNING:

SBZA is only a lane changing aid and does not replace driver vision. SBZA does not detect: . Vehicles outside the side blind zones which

may be rapidly approaching.

. Pedestrians, bicyclists, or animals. Failure to use proper care when changing lanes may result in damage to the vehicle, injury, or death. Always check the outside and rearview mirrors, glance over your shoulder, and use the turn signal before changing lanes.

When the system detects a vehicle in the side blind zone, amber SBZA displays light up in the side mirrors. This indicates that it may be unsafe to change lanes.

3-60

SBZA Detection Zones The SBZA sensor covers a zone of approximately one lane over from both sides of the vehicle, 3.5 m (11 ft). This zone starts at each side mirror and goes back approximately 5.0 m (16 ft). The height of the zone is approximately between 0.5 m (1.5 ft) and 2.0 m (6 ft) off the ground.

Chevrolet Tahoe/Suburban Owner Manual - 2010

Black plate (61,1)

Use caution while changing lanes when towing a trailer, as the SBZA detection zones do not change when a trailer is towed. How the System Works

Left Side Mirror Display Right Side Mirror Display

When the vehicle is started, both outside mirror displays will briefly come on to indicate that the system is operating. When the vehicle is moving forward, the left or right side mirror SBZA display will light up if a vehicle is detected in that blind zone. If the turn signal is activated and a vehicle is also detected on the same side, the SBZA display will flash to give you extra warning not to change lanes. SBZA displays do not come on while the vehicle is approaching or passing other vehicles. At speeds greater then 32 km/h (20 mph), SBZA displays may come on when a vehicle you have passed remains in or drops back into the detection zone.

SBZA can be disabled through the Driver Information Center (DIC). See Driver Information Center (DIC) on page 4‑47 for more information. If the SBZA is disabled by the driver, the SBZA mirror displays will not light up during normal driving. When the System Does Not Seem To Work Properly Occasional missed alerts can occur under normal circumstances and will increase in wet conditions. The system does not need to be serviced due to an occasional missed alert. The number of missed alerts will increase with increased rainfall or road spray. If the SBZA displays do not light up when the system is on and vehicles are in the blind zone, the system may need service. Take the vehicle to your dealer. SBZA is designed to ignore stationary objects; however, the system may occasionally light up due to guard rails, signs, trees, shrubs, and other stationary objects. This is normal system operation, the vehicle does not need service. SBZA does not operate when the left or right corners of the rear bumper are covered with mud, dirt, snow, ice, slush, or in heavy rainstorms. For cleaning instructions, see Washing Your Vehicle on page 6‑111. If the DIC still displays the SIDE BLIND ZONE SYS. UNAVAILABLE message after cleaning the bumper, see your dealer.

When the System Does Not Seem To Work Properly The rear vision camera system might not work properly or display a clear image if:

The RVC is turned off. See “Turning the Rear Camera System On or Off” earlier in this section. It is dark. The sun or the beam of headlights is shining directly into the camera lens. Ice, snow, mud, or anything else builds up on the camera lens. Clean the lens, rinse it with water, and wipe it with a soft cloth. The back of the vehicle is in an accident, the position and mounting angle of the camera can change or the camera can be affected. Be sure to have the camera and its position and mounting angle checked at your dealer.

The rear vision camera system display in the rearview mirror may turn off or not appear as expected due to one of the following conditions. If this occurs the left indicator light on the mirror will flash.

. A slow flash may indicate a loss of video signal,

or no video signal present during the reverse cycle. . A fast flash may indicate that the display has been

on for the maximum allowable time during a reverse cycle, or the display has reached an Over Temperature limit. The fast flash conditions are used to protect the video device from high temperature conditions. Once conditions return to normal the device will reset and the green indicator will stop flashing.

During any of these fault conditions, the display will be blank and the indicator will continue to flash as long as the vehicle is in R (Reverse) or until the conditions return to normal. Pressing and holding z when the left indicator light is flashing will turn off the video display along with the left indicator light.

Universal Home Remote System See Radio Frequency Statement on page 8‑19 for information regarding Part 15 of the Federal Communications Commission (FCC) rules and Industry Canada Standards RSS-210/220/310. Universal Home Remote System Operation (With Three Round LED)

This vehicle may have the Universal Home Remote System. If there are three round Light Emitting Diode (LED) indicator lights above the Universal Home Remote buttons, follow the instructions below.

3-68

This system provides a way to replace up to three remote control transmitters used to activate devices such as garage door openers, security systems, and home automation devices. Do not use this system with any garage door opener that does not have the stop and reverse feature. This includes any garage door opener model manufactured before April 1, 1982. Read the instructions completely before attempting to program the transmitter. Because of the steps involved, it may be helpful to have another person assist with programming the transmitter. Be sure to keep the original remote control transmitter for use in other vehicles, as well as, for future programming. Only the original remote control transmitter is needed for Fixed Code programming. The programmed buttons should be erased when the vehicle is sold or the lease ends. See “Erasing Universal Home Remote Buttons” later in this section. Park the vehicle outside of the garage when programming a garage door. Be sure that people and objects are clear of the garage door or gate that is being programmed.

To program up to three devices:

Your hand held transmitter can have between eight to 12 dip switches depending on the brand of transmitter. The garage door opener receiver (motor head unit) could also have a row of dip switches that can be used when programming the Universal Home Remote. If the total number of switches on the motor head and hand held transmitter are different, or if the dip switch settings are different, use the dip switch settings on the motor head unit to program the Universal Home Remote. The motor head dip switch settings can also be used when the original hand held transmitter is not available.

1. To verify that the garage door opener is a Fixed Code unit, remove the battery cover on the hand held transmitter supplied by the manufacturer of the garage door opener motor. If there are a row of dip switches similar to the graphic above, the garage door opener is a Fixed Code unit. If you do not see a row of dip switches, return to the previous section for Programming Universal Home Remote – Rolling Code.
