your vehicle and the airbag system. To purchase a service manual, see Service Publications Ordering Information on page 465. {CAUTION: For up to 10 seconds, after the ignition is turned off and the battery is disconnected, an airbag can still inﬂate during improper service. You can be injured if you are close to an airbag when it inﬂates. Avoid yellow connectors. They are probably part of the airbag system. Be sure to follow proper service procedures, and make sure the person performing work for you is qualiﬁed to do so. The airbag system does not need regular maintenance. 80 Adding Equipment to Your Airbag-Equipped Vehicle Q: Is there anything I might add to the front or sides of the vehicle that could keep the airbags from working properly? A: Yes. If you add things that change your vehicle’s frame, bumper system, height, front end or side sheet metal, they may keep the airbag system from working properly. Also, the airbag system may not work properly if you relocate any of the airbag sensors. If you have any questions about this, you should contact Customer Assistance before you modify your vehicle. The phone numbers and addresses for Customer Assistance are in Step Two of the Customer Satisfaction Procedure in this manual. See Customer Satisfaction Procedure on page 448. Q: Because I have a disability, I have to get my vehicle modiﬁed. How can I ﬁnd out whether this will affect my airbag system? A: Changing or moving any parts of the front seats, safety belts, the airbag sensing and diagnostic module, rollover sensor module, instrument panel, steering wheel, ceiling headliner, ceiling and pillar garnish trim, roof-mounted rollover airbag modules, or airbag wiring can affect the operation of the airbag system. If you have questions, call Customer Assistance. The phone numbers and addresses for Customer Assistance are in Step Two of the Customer Satisfaction Procedure in this manual. See Customer Satisfaction Procedure on page 448. 81 If you damage the covering for the Notice: driver’s or the right front passenger’s airbag, or the side impact airbag covering (if equipped) on the ceiling near the side windows, the airbag may not work properly. You may have to replace the airbag module in the steering wheel, both the airbag module and the instrument panel for the right front passenger’s airbag, or side impact airbag module and ceiling covering for roof-mounted side impact airbags (if equipped.) Do not open or break the airbag coverings. Restraint System Check Checking the Restraint Systems Now and then, make sure the safety belt reminder light and all your belts, buckles, latch plates, retractors and anchorages are working properly. Look for any other loose or damaged safety belt system parts. If you see anything that might keep a safety belt system from doing its job, have it repaired. See Care of Safety Belts on page 409 for more information. Torn or frayed safety belts may not protect you in a crash. They can rip apart under impact forces. If a belt is torn or frayed, get a new one right away. Also look for any opened or broken airbag covers, and have them repaired or replaced. The airbag system does not need regular maintenance. 82 Replacing Restraint System Parts After a Crash {CAUTION: A crash can damage the restraint systems in your vehicle. A damaged restraint system may not properly protect the person using it, resulting in serious injury or even death in a crash. To help make sure your restraint systems are working properly after a crash, have them inspected and any necessary replacements made as soon as possible. If you have had a crash, do you need new belts or LATCH system parts? After a very minor collision, nothing may be necessary. But if the belts were stretched, as they would be if worn during a more severe crash, then you need new parts. If the LATCH system was being used during a more severe crash, you may need new LATCH system parts. If belts are cut or damaged, replace them. Collision damage also may mean you will need to have LATCH system, safety belt or seat parts repaired or replaced. New parts and repairs may be necessary even if the belt or LATCH system was not being used at the time of the collision. If an airbag inﬂates, you will need to replace airbag system parts. See the part on the airbag system earlier in this section. If the frontal airbags inﬂate you will also need to replace the driver and front passenger’s safety belt retractor assembly. Be sure to do so. Then the new retractor assembly will be there to help protect you in a collision. After a crash you may need to replace the driver and front passenger’s safety belt retractor assemblies, even if the frontal airbags have not deployed. The driver and front passenger’s safety belt retractor assemblies contain the safety belt pretensioners. Have your safety belt pretensioners checked if your vehicle has been in a collision, or if your airbag readiness light stays on after you start your vehicle or while you are driving. See Airbag Readiness Light on page 178. 83 ✍ NOTES 84 Section 2 Features and Controls Keys .............................................................. 87 Remote Keyless Entry (RKE) System .......... 88 Remote Keyless Entry (RKE) System Operation .................................... 89 Doors and Locks .......................................... 92 Door Locks ................................................. 92 Power Door Locks ....................................... 93 Programmable Automatic Door Locks .......... 94 Lockout Protection ....................................... 94 Swing-gate .................................................. 95 Windows ....................................................... 96 Power Windows .......................................... 97 Sun Visors .................................................. 97 Theft-Deterrent Systems ............................... 98 Content Theft-Deterrent ............................... 98 Passlock® .................................................. 100 Starting and Operating Your Vehicle ......... 101 New Vehicle Break-In ................................ 101 Ignition Positions ....................................... 101 Retained Accessory Power (RAP) ............. 103 Starting the Engine .................................... 103 Engine Coolant Heater .............................. 105 Automatic Transmission Operation ............. 106 Manual Transmission Operation ................. 109 Full-Time Four-Wheel Drive ....................... 111 Parking Brake ........................................... 116 Shifting Into Park (P) (Automatic Transmission) ....................... 117 Shifting Out of Park (P) (Automatic Transmission) ....................... 119 Parking Your Vehicle (Manual Transmission) ........................... 119 Parking Over Things That Burn ................. 119 Engine Exhaust ......................................... 120 Running the Engine While Parked ............. 121 85 Section 2 Features and Controls Storage Areas ............................................. 143 Glove Box ................................................. 143 Cupholder(s) .............................................. 143 Front Seat Storage Net ............................. 143 Front Armrest Storage Area ....................... 143 Luggage Carrier ........................................ 144 Rear Storage Area .................................... 146 Convenience Net ....................................... 146 Cargo Cover ............................................. 146 Cargo Tie Downs ...................................... 146 Sunroof ....................................................... 147 Mirrors ......................................................... 122 Automatic Dimming Rearview Mirror with OnStar®, Compass and Temperature Display .............................. 122 Automatic Dimming Rearview Mirror with Compass and Temperature Display ........ 125 Outside Power Mirrors ............................... 128 Outside Convex Mirror ............................... 128 OnStar® System .......................................... 129 Universal Home Remote System ................ 132 Universal Home Remote System (With Three Round LED) ....................... 132 Universal Home Remote System (With One Triangular LED) ..................... 133 Universal Home Remote System Operation (With Three Round LED) ....... 134 Universal Home Remote System Operation (With One Triangular LED) ..... 139 86 Keys {CAUTION: Leaving children in a vehicle with the ignition key is dangerous for many reasons. They could operate the power windows or other controls or even make the vehicle move. The children or others could be badly injured or even killed. Do not leave the keys in a vehicle with children. 87 There is one double-sided key for the ignition, and driver’s door lock. When a new vehicle is delivered, the dealer provides the owner with a pair of identical keys and a key code number. The key code number tells your dealer or a qualiﬁed locksmith how to make extra keys. Keep this number in a safe place. If you lose your keys, you will be able to have new ones made easily using this number. Your dealer should also have this number. Notice: vehicle, you may have to damage the vehicle to get in. Be sure you have spare keys. If you ever lock your keys in your 88 If you ever do get locked out of your vehicle call the GM Roadside Assistance Center. See Roadside Assistance Program on page 454. Remote Keyless Entry (RKE) System Your Remote Keyless Entry (RKE) system operates on a radio frequency subject to Federal Communications Commission (FCC) Rules and with Industry Canada. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: 1. This device may not cause interference. 2. This device must accept any interference received, including interference that may cause undesired operation of the device. This device complies with RSS-210 of Industry Canada. Operation is subject to the following two conditions: 1. This device may not cause interference. 2. This device must accept any interference received, including interference that may cause undesired operation of the device. Changes or modiﬁcations to this system by other than an authorized service facility could void authorization to use this equipment. At times you may notice a decrease in operating range. This is normal for any RKE system. If the transmitter does not work or if you have to stand closer to your vehicle for the transmitter to work, try this: (cid:127) Check the distance. You may be too far from your vehicle. You may need to stand closer during rainy or snowy weather. (cid:127) Check the location. Other vehicles or objects may be blocking the signal. Take a few steps to the left or right, hold the transmitter higher, and try again. (cid:127) Check to determine if battery replacement is necessary. See “Battery Replacement” under Remote Keyless Entry (RKE) System Operation on page 89. If you are still having trouble, see your dealer or a qualiﬁed technician for service. (cid:127) Remote Keyless Entry (RKE) System Operation You can lock and unlock the vehicle’s doors and disarm or arm the theft-deterrent system from about 3 feet (1 m) up to 30 feet (9 m) away using the remote keyless entry transmitter. See Content Theft-Deterrent on page 98 for additional information. UNLOCK: Press this button to unlock the driver’s door and turn on the interior lamps. The parking lamps may also ﬂash, and the horn may chirp, when this button is pressed. Press the unlock button again within three seconds and all of the doors will unlock. 89 LOCK: Press this button to lock all the doors. The parking lamps may also ﬂash and the horn may chirp when this button is pressed. If a door is open or ajar when the lock button is pressed, the doors will lock, but the theft-deterrent system will not arm until the open door is closed. You can program different feedback modes through the Driver Information Center (DIC). To program the feedback modes, see “Remote Keyless Entry Feedback” under DIC Controls and Displays on page 192. L(Panic): Press this button to make the horn sound and the headlamps and taillamps ﬂash for up to 30 seconds. To turn them off, do one of these three things: wait for 30 seconds; press the panic button again; or start the vehicle. Matching Transmitter(s) to Your Vehicle Each remote keyless entry transmitter is coded to prevent another transmitter from unlocking your vehicle. If a transmitter is lost or stolen, a replacement can be purchased through your dealer. Remember to bring any remaining transmitters with you when you go to your dealer. When the dealer matches the replacement transmitter to your vehicle, any remaining transmitters must also be matched. Once your dealer has coded the new transmitter, the lost transmitter will not unlock your vehicle. Each vehicle can have a maximum of four transmitters matched to it. 90 To replace the battery, do the following: Battery Replacement Under normal use, the battery in the remote keyless entry transmitter should last about two years. You can tell the battery is weak if the transmitter will not work at the normal range in any location. If you have to get close to your vehicle before the transmitter works, it is probably time to change the battery. Notice: When replacing the battery, use care not to touch any of the circuitry. Static from your body transferred to these surfaces may damage the transmitter. 1. Insert a coin, or similar object, in the slot between the covers of the transmitter housing. Gently pry the transmitter apart. 2. Remove and replace the battery with a three-volt CR2032 or equivalent battery. 3. Align the covers and snap them together. 4. Check the operation of the transmitter. 91 CAUTION: (Continued) (cid:127) Young children who get into unlocked vehicles may be unable to get out. A child can be overcome by extreme heat and can suffer permanent injuries or even death from heat stroke. Always lock your vehicle whenever you leave it. (cid:127) Outsiders can easily enter through an unlocked door when you slow down or stop your vehicle. Locking your doors can help prevent this from happening. Doors and Locks Door Locks {CAUTION: Unlocked doors can be dangerous. (cid:127) Passengers, especially children, can easily open the doors and fall out of a moving vehicle. When a door is locked, the handle will not open it. You increase the chance of being thrown out of the vehicle in a crash if the doors are not locked. So, wear safety belts properly and lock the doors whenever you drive. CAUTION: (Continued) 92 There are several ways to lock and unlock your vehicle. From the outside, use the key in the driver’s door or use the remote keyless entry transmitter. Power Door Locks The power door lock switches are located on the driver’s and the front passenger’s armrests. From the inside, use the manual lock levers or power door lock switch. Driver’s side shown Press L (lock) to lock all the doors at once. To unlock all the doors, press U (unlock). 93 Lockout Protection This feature protects you from locking your key in the vehicle when the key is in the ignition and a door is open. If the power door lock switch is pressed when a door is open and the key is in the ignition, all of the doors will lock and then the driver’s door will unlock. A chime will sound to indicate that the key has been left in the ignition. Programmable Automatic Door Locks If your vehicle has an automatic transmission, it is programmed from the factory to lock the doors automatically when the shift lever is moved out of PARK (P). All the doors will unlock when the shift lever is moved back into PARK (P). If your vehicle has a manual transmission, it is programmed from the factory to lock the doors automatically when the vehicle speed is greater than 15 mph (24 km/h). The doors will unlock when the key is removed from the ignition. To personalize the automatic door locks, see “Automatic Door Locks” under DIC Controls and Displays on page 192. 94 Swing-gate To lock or unlock the swing-gate, use the power door lock switch or the remote keyless entry transmitter. {CAUTION: Make sure the swing-gate is completely closed. Driving with the swing-gate open could injure pedestrians or damage the vehicle. To open the swing-gate, pull the door handle. Pull the swing-gate rearward slightly and it will automatically open. 95 Windows {CAUTION: Leaving children, helpless adults, or pets in a vehicle with the windows closed is dangerous. They can be overcome by the extreme heat and suffer permanent injuries or even death from heat stroke. Never leave a child, a helpless adult, or a pet alone in a vehicle, especially with the windows closed in warm or hot weather. 96 Power Windows The power window controls are located on the armrest of each door. The driver’s door has switches for the passenger windows as well. Your power windows will work when the ignition is in ACC (Accessory) or ON, or when Retained Accessory Power (RAP) is active. See Retained Accessory Power (RAP) on page 103. Pull up the front edge of the control to raise the window. Press the front edge of the control down to lower the window. Express-Down Window The driver’s window has an express-down feature that allows you to lower the window without holding the switch. Press the front edge of the switch past the ﬁrst position to activate the express-down mode. The express-down mode can be canceled at any time by pulling up on the switch. To open the window partway, press the front of the switch to the ﬁrst position until the window is at the desired level. Window Lockout o(Window Lockout): The window lockout button is located forward of the window switches. This feature disables the passenger’s window switches when the button is pressed. Press the button again to turn the lockout off. A red band on the side of the button can be seen when the windows are not locked out. Sun Visors To block glare, pull the visor down. It can also be detached from the center mount and moved to the side to block glare from that direction. There are extenders that can be pulled out for further coverage. 97 Visor Vanity Mirror Your vehicle has a vanity mirror located on the driver’s and passenger’s visor. Illuminated Visor Vanity Mirror Your vehicle may have an illuminated vanity mirror on both visors. Lift the cover on the mirror and the lights will automatically come on. Theft-Deterrent Systems Vehicle theft is big business, especially in some cities. Although your vehicle has a number of theft-deterrent features, we know that nothing we put on it can make it impossible to steal. Content Theft-Deterrent Your vehicle has a content theft-deterrent alarm system. To activate the content theft-deterrent system, do the following: 1. Close all the doors. 2. Lock the doors with the remote keyless entry transmitter. The security light, located on the instrument panel cluster, will ﬂash. If the lock button on the remote keyless entry transmitter is pressed, but a door is open, the doors will lock, the lights may ﬂash and the horn may sound. Close the open door and the alarm system will arm. If a locked door is not opened using the remote keyless entry transmitter, or by OnStar®, the alarm will go off. First, a pre-alarm will sound the horn at reduced intensity for 10 seconds. Then, the front turn signal lamps will ﬂash for two minutes, and the horn will sound for two minutes. The alarm will then turn off to save battery power. Starting the engine with the correct key will shut off the pre-alarm or alarm at any time. Remember, the theft-deterrent system will not activate if you lock the doors with the key, the manual door lock, or power door lock switch. 98 The system can only be activated using the remote keyless entry transmitter, or by OnStar®. See OnStar® System on page 129 for additional information. You should also remember that you can start your vehicle with the correct key if the alarm has been set off. Here is how to avoid setting off the alarm by accident: (cid:127) If you do not want to arm the theft-deterrent system, the vehicle should be locked with the manual door lock lever, the power door lock switch, or the key, after the doors are closed. If the content theft-deterrent system is armed, unlock the doors by pressing the unlock button on the remote keyless entry transmitter or by OnStar®. Unlocking a door any other way will activate the alarm. (cid:127) If you set off the alarm by accident, you can turn it off by pressing unlock on the remote keyless entry transmitter, starting the vehicle with the correct key, or by having OnStar® unlock the doors. The alarm will not stop if you try to unlock a door any other way. Testing the Alarm The alarm can be tested by following these steps: 1. From inside the vehicle, activate the system by locking the doors with the remote keyless entry transmitter. 2. Unlock the door with the manual door lock and open the door. This should set off the pre-alarm. Wait 10 seconds for the full alarm to activate. 3. To turn the alarm off, press the unlock button on the remote keyless entry transmitter or start the engine. If the alarm does not sound when it should but the lights 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 417. If the alarm does not sound or the front turn signal lamps do not ﬂash, see your dealer for service. 99 Passlock® Your vehicle has the Passlock® theft-deterrent system. Passlock® is a passive theft-deterrent system. Passlock® enables fuel if the ignition lock cylinder is turned with a valid key. If an incorrect key is used or the ignition lock cylinder is tampered with, the fuel system is disabled and the vehicle will not start. During normal operation, the security light will turn off approximately ﬁve seconds after the engine is started. See Security Light on page 190. If the engine stalls and the security light ﬂashes, wait about 10 minutes until the light stops ﬂashing before trying to restart the engine. Remember to release the key from START as soon as the engine starts. If the engine does not start after three tries, the vehicle needs service. If the engine is running and the security light comes on, you will be able to restart the engine if you turn the engine off. However, your Passlock® system is not working properly and must be serviced by your dealer. Your vehicle is not protected by Passlock® at this time. See your dealer for service. In an emergency, call the Roadside Assistance Center. See Roadside Assistance Program on page 454. 100 Starting and Operating Your Vehicle New Vehicle Break-In Notice: Your vehicle does not need an elaborate break-in. But it will perform better in the long run if you follow these guidelines: (cid:127) Keep your speed at 55 mph (88 km/h) or less for the ﬁrst 500 miles (805 km). (cid:127) 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. (cid:127) Avoid making hard stops for the ﬁrst 200 miles (322 km) or so. During this time your 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. (cid:127) Do not tow a trailer during break-in. See Towing a Trailer on page 297 for the trailer towing capabilities of your vehicle and more information. Ignition Positions With the key in the ignition switch, you can turn to four different positions. LOCK (A): This position locks the ignition. It also locks the transmission on automatic transmission vehicles. It will locks the steering wheel on manual transmission vehicles when the key is removed. It is a theft-deterrent feature. You will only be able to remove your key when the ignition is turned to LOCK. If you have an automatic transmission, the ignition switch cannot be turned to LOCK unless the shift lever is in PARK (P). Following break-in, engine speed and load can be gradually increased. 101 Notice: Using a tool to force the key from the ignition switch could cause damage or break the key. Use the correct key and turn the key only with your hand. Make sure the key is all the way in. If it is, turn the steering wheel left and right while you turn the key hard. If none of this works, then your vehicle needs service. ACC (ACCESSORY) (B): This is the position in which you can operate your electrical accessories or items plugged into the accessory power outlets. On automatic transmission vehicles, this position unlocks the ignition. On manual transmission vehicles, it unlocks the ignition and steering wheel. Use this position if your vehicle must be pushed or towed. ON (C): This is the position that the switch returns to after you start your engine and release the switch. The switch stays in ON when the engine is running. But even when the engine is not running, you can use ON to operate the electrical accessories and to display some instrument panel cluster warning and indicator lights. 102 The transmission is also unlocked in this position on automatic transmission vehicles. The battery could be drained if you leave the key in the ACC or ON position with the engine off. You may not be able to start your vehicle if the battery is allowed to drain for an extended period of time. START (D): This is the position that starts the engine. When the engine starts, release the key. The ignition switch returns to ON for driving. When the engine is not running, ACC and ON allows you to operate the electrical accessories, such as the radio or items plugged into the accessory power outlets. A warning tone will sound if you open the driver’s door when the ignition is in ACC or LOCK and the key is in the ignition. Key In the Ignition Never leave your vehicle with the keys inside, as it is an easy target for joy riders or thieves. If you leave the key in the ignition and park your vehicle, a chime will sound, when you open the driver’s door. Always remember to remove your key from the ignition and take it with you. This will lock your ignition and transmission. Also, always remember to lock the doors. The battery could be drained if you leave the key in the ignition while your vehicle is parked. You may not be able to start your vehicle after it has been parked for an extended period of time. Retained Accessory Power (RAP) Your vehicle has Retained Accessory Power (RAP) which allows certain features of your vehicle to continue working for up to 20 minutes after the ignition key is turned to LOCK. The radio, front wipers, power windows, and a sunroof if your vehicle has one, will work when the ignition key is in ON or ACC. Once the key is turned from ON to LOCK, these features continue working for up to 20 minutes or until a door is opened. Starting the Engine Place the transmission in the proper gear. Automatic Transmission Move your shift lever to PARK (P) or NEUTRAL (N). Your engine will not start in any other position -- this is a safety feature. To restart when you are already moving, use NEUTRAL (N) only. Notice: Do not try to shift to PARK (P) if your vehicle is moving. If you do, you could damage the transmission. Shift to PARK (P) only when your vehicle is stopped. Manual Transmission The shift lever should be in the NEUTRAL position and the parking brake engaged. Hold the clutch pedal to the ﬂoor and start the engine. Your vehicle will not start if the clutch pedal is not all the way down. That is a safety feature. 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. 103 Your 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 stoppes 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 or LOCK 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 allow the cranking motor to 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. 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: Your engine is designed to work with the electronics in your 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, your engine might not perform properly. Any resulting damage would not be covered by your vehicle’s warranty. 104 Engine Coolant Heater Your vehicle may have this feature. In very cold weather, 0°F (–18°C) or colder, the engine coolant heater can help. You will get easier starting and better fuel economy during engine warm-up. Usually, the coolant heater should be plugged in a minimum of four hours prior to starting your vehicle. At temperatures above 32°F (0°C), use of the coolant heater is not required. Your vehicle may also have an internal thermostat in the plug end of the cord. This will prevent operation of the engine coolant heater when the temperature is at or above 0F (−18C) as noted on the cord. To Use the Engine Coolant Heater 1. Turn off the engine. 2. Open the hood and unwrap the electrical cord. The cord is located in the engine compartment behind the underhood fuse block on the driver’s side of the vehicle. 3. Plug it into a normal, grounded 110-volt AC outlet. {CAUTION: 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. How long should you keep the coolant heater plugged in? The answer depends on the outside temperature, the kind of oil you have, and some other things. Instead of trying to list everything here, we ask that you contact your dealer in the area where you will be parking your vehicle. The dealer can give you the best advice for that particular area. 105 Automatic Transmission Operation PARK (P): This position locks your rear wheels. It is the best position to use when you start the engine because your vehicle cannot move easily. {CAUTION: It is dangerous to get out of your vehicle if the shift lever is not fully in PARK (P) with the parking brake ﬁrmly set. Your vehicle can roll. Do not leave your 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 your vehicle will not move, even when you are on fairly level ground, always set your parking brake and move the shift lever to PARK (P). See Shifting Into Park (P) (Automatic Transmission) on page 117. If you are pulling a trailer, see Towing a Trailer on page 297. The automatic transmission has a shift lever on the console. It features an electronic shift position indicator within the instrument cluster. This display must be powered anytime the shift lever is capable of being moved out of PARK (P). This means that if your key is turned off, but not in LOCK, there will be a small current drain on your battery which could discharge your battery over a period of time. If you need to leave your key in the ignition but not in LOCK for an extended period, it is recommended that you disconnect the battery cable from the battery to prevent discharging your battery. There are several different positions for your shift lever. 106 Make sure the shift lever is fully in PARK (P) before starting the engine. Your vehicle has an automatic transmission shift lock control system. You must fully apply your regular brakes ﬁrst and then press the shift lever button before you can shift from PARK (P) when the ignition key is in ON. If you cannot shift out of PARK (P), ease pressure on the shift lever and push the shift lever all the way into PARK (P) as you maintain brake application. Then press the shift lever button and move the shift lever into another gear. See Shifting Out of Park (P) (Automatic Transmission) on page 119 REVERSE (R): Use this gear to back up. Notice: Shifting to REVERSE (R) while your vehicle is moving forward could damage the transmission. The repairs would not be covered by your warranty. Shift to REVERSE (R) only after your vehicle is stopped. To rock your vehicle back and forth to get out of snow, ice, or sand without damaging your transmission, see If Your Vehicle is Stuck in Sand, Mud, Ice, or Snow on page 286. NEUTRAL (N): In this position, your engine does not connect with the wheels. To restart when you are already moving, use NEUTRAL (N) only. {CAUTION: Shifting into a drive gear while your engine is running at high speed is dangerous. Unless your foot is ﬁrmly on the brake pedal, your vehicle could move very rapidly. You could lose control and hit people or objects. Do not shift into a drive gear while your engine is running at high speed. Notice: Shifting out of PARK (P) or NEUTRAL (N) with the engine running at high speed may damage the transmission. The repairs would not be covered by your warranty. Be sure the engine is not running at high speed when shifting your vehicle. 107 SECOND (2): This position reduces vehicle speed even more than THIRD (3) without using your brakes. You can use SECOND (2) on hills. It can help control your speed as you go down steep mountain roads, but then you would also want to use your brakes off and on. FIRST (1): This position reduces vehicle speed even more than SECOND (2) without using your brakes. You can use it on very steep hills, or in deep snow or mud. If the shift lever is put in FIRST (1) while the vehicle is moving forward, the transmission will not shift into ﬁrst gear until the vehicle is going slowly enough. 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 your warranty. If you are stuck, do not spin the tires. When stopping on a hill, use the brakes to hold the vehicle in place. DRIVE (D): This position is for normal driving. It provides the best fuel economy for your vehicle. If you need more power for passing, and you are: (cid:127) Going less than about 35 mph (55 km/h), push your accelerator pedal about halfway down. (cid:127) Going about 35 mph (55 km/h) or more, push the accelerator all the way down. Downshifting the transmission in slippery road conditions could result in skidding, see “Skidding” under Loss of Control on page 249. DRIVE (D) can be used when towing a trailer. You may want to shift the transmission to THIRD (3) or, if necessary, a lower gear if the transmission shifts too often under heavy loads and/or hilly conditions. THIRD (3): This position is also used for normal driving. However it reduces vehicle speed more than DRIVE (D) without using your brakes. You might choose THIRD (3) instead of DRIVE (D) when driving on hilly, winding roads, when towing a trailer, so there is less shifting between gears and when going down a steep hill. 108 SECOND (2): Press the clutch pedal as you let up on the accelerator pedal and shift into SECOND (2). Then, slowly let up on the clutch pedal as you press the accelerator pedal. THIRD, FOURTH AND FIFTH (3, 4 and 5): Shift into THIRD (3), FOURTH (4) and FIFTH (5) the same way you do for SECOND (2). Slowly let up on the clutch pedal as you press the accelerator pedal. To stop, let up on the accelerator pedal and press the brake pedal. Just before the vehicle stops, press the clutch pedal and the brake pedal, and shift to NEUTRAL. NEUTRAL: Use this position when you start or idle your engine. Manual Transmission Operation This is your shift pattern. Here is how to operate your manual transmission: FIRST (1): Press the clutch pedal and shift into FIRST (1). Then, slowly let up on the clutch pedal as you slowly press down on the accelerator pedal. You can shift into FIRST (1) when you are going less than 20 mph (30 km/h). If you have come to a complete stop and it is hard to shift into FIRST (1), put the shift lever in NEUTRAL and let up on the clutch. Then press the clutch pedal back down and shift into FIRST (1). 109 REVERSE (R): To back up, press the clutch pedal. After the vehicle stops, shift into REVERSE (R). Slowly let up on the clutch pedal as you press the accelerator pedal. If it is hard to shift, let the shift lever return to NEUTRAL and release the clutch pedal. Then press the clutch again and shift into REVERSE (R). Do not attempt to shift into the ﬁfth gear position prior to shifting into REVERSE (R). Your transmission has a lock out feature which prevents a ﬁfth gear to reverse gear shift. Notice: Shifting to REVERSE (R) while your vehicle is moving forward could damage the transmission. The repairs would not be covered by your warranty. Shift to REVERSE (R) only after your vehicle is stopped. Use REVERSE (R), along with the parking brake, for parking your vehicle. Up-Shift Light This light will show you when to shift to the next higher gear for best fuel economy. When this light comes on, you can shift to the next higher gear if weather, road and traffic conditions permit. For the best fuel economy, accelerate slowly and shift when the light comes on. While you accelerate, it is normal for the light to go on and off if you quickly change the position of the accelerator. Ignore the shift light when you downshift. If your vehicle has four-wheel drive and has a manual transmission, disregard the shift light when the transfer case is in four-wheel low. For more information, see Up-Shift Light (Manual Transmission) on page 181. Shift Speeds {CAUTION: If you skip a gear when you downshift, you could lose control of your vehicle. You could injure yourself or others. Do not shift down more than one gear at a time when you downshift. 110 Full-Time Four-Wheel Drive Full-Time Four-Wheel Drive sends your engine’s driving power to all four wheels for extra traction. To get the most out of Full-Time Four-Wheel Drive, you must be familiar with its operation. Transfer Case Buttons The transfer case buttons are located to the right of the instrument panel cluster. Use these switches to shift into and out of the different Full-Time Four-Wheel Drive modes. You can choose between four modes: 4 m (Four-Wheel High): This setting is used for driving in most street and highway situations. You can also use this setting for light or variable off-road conditions. N (NEUTRAL): Shift the vehicle’s transfer case to NEUTRAL only when towing your vehicle. See Recreational Vehicle Towing on page 295 or Towing Your Vehicle on page 294 for more information. Notice: Driving on pavement in Four-Wheel High Lock or Four Wheel Low Lock for extended periods may cause premature wear on your vehicle’s powertrain and tires. Do not drive in Four-Wheel High Lock or Four-Wheel Low Lock on pavement for extended periods. 4 m Q (Four-Wheel-High Lock): Use this mode when you need extra traction in most off-road situations such as sand, mud, snow or level, rocky trails. 111 It will remain lit when the shift is complete. If for some reason the transfer case cannot make a requested shift, it will return to the last chosen setting. If the SERV 4WD message on the Driver Information Center (DIC) stays on, you should take your vehicle to your dealer for service. See Service 4WD message under DIC Warnings and Messages on page 196. Shifting between Four-Wheel High and Four-Wheel-High Lock With the vehicle traveling less than 45 mph (72 km/h), press and release the Four-Wheel High or Four-Wheel-High Lock button. The indicator light will ﬂash while shifting. It will remain lit when the shift is complete. It may be necessary to drive backwards while turning for a distance of 25 feet (7.5 m) to get the lock feature to disengage. Notice: Operating your vehicle in Four-Wheel-Low Lock above 30 mph (48 km/h) for any extended period of time could cause damage to the transfer case. Do not operate your vehicle in Four-Wheel-Low Lock above 30 mph (48 km/h) for extended periods. 4 n Q (Four-Wheel-Low Lock): This mode delivers extra torque to all four wheels and is used for extreme off-road conditions. You might choose 4-Wheel-Low Lock if you are driving in off-road situations, such as, deep sand, mud, or snow and climbing or descending steep hills. If the vehicle has a locking rear axle, when in this mode you can also choose to lock the rear axle for additional traction in extreme off-road situations. See Locking Rear Axle on page 243. Indicator lights in the buttons show which mode you are in. The indicator lights will come on brieﬂy when you turn on the ignition the mode the vehicle is in will stay on. If the lights do not come on, you should take your vehicle to your dealer for service. An indicator light will ﬂash while shifting the transfer case. 112 Shifting into Four-Wheel Low Lock Notice: Shifting the transmission into gear before the indicator light stops ﬂashing could cause damage to the transfer case. Always wait until the indicator light stops ﬂashing before putting the transmission back in gear. To shift into Four-Wheel-Low Lock, the ignition must be in ON and the vehicle must be stopped or moving less than 3 mph (5 km/h) with the transmission in NEUTRAL (N). The preferred method for shifting into Four-Wheel Low is to have your vehicle moving 1 to 2 mph (1.6 to 3.2 km/h). Press and release the Four-Wheel-Low Lock button. If your vehicle has a manual transmission, the clutch pedal must be pressed to the ﬂoor while you press the Four-Wheel-Low Lock button, or the shift will not be completed. You must wait for the Four-Wheel-Low Lock indicator light to stop ﬂashing and remain lit before shifting your transmission in gear. It is normal for your vehicle to have engagement noise and bump when shifting between Four-Wheel Low and Four-Wheel High ranges or from NEUTRAL with the engine running. If the Four-Wheel-Low Lock button is pressed when your vehicle is in gear and/or moving too fast, the Four-Wheel-Low Lock indicator light will ﬂash for 15 seconds and not complete the shift unless your vehicle is moving less than 3 mph (5 km/h) and the transmission is in NEUTRAL (N). After 15 seconds the transfer case will return to the last chosen setting. Shifting Out of Four-Wheel-Low Lock Notice: Shifting the transmission into gear before the indicator light stops ﬂashing could cause damage to the transfer case. Always wait until the indicator light stops ﬂashing before putting the transmission back in gear. To shift out of Four-Wheel-Low Lock, your vehicle must be stopped or moving less than 3 mph (5 km/h) with the transmission in NEUTRAL (N) and the ignition in ON. The preferred method for shifting out of Four-Wheel-Low Lock is to have your vehicle moving 1 to 2 mph (1.6 to 3.2 km/h). 113 Press and release the Four-Wheel High or Four-Wheel-High Lock button. If your vehicle has a manual transmission, the clutch pedal must be pressed to the ﬂoor while you press the Four-Wheel High or Four-Wheel-High Lock button, or the shift will not be completed. You must wait for the Four-Wheel High or Four-Wheel-High Lock indicator light to stop ﬂashing and remain lit before shifting your transmission into gear. It is normal for your vehicle to have engagement noise and bump when shifting between Four-Wheel Low and Four-Wheel High ranges or from NEUTRAL with the engine running. If the Four-Wheel High or Four-Wheel-High Lock button is pressed when your vehicle is in gear and/or moving too fast, the Four-Wheel High or Four-Wheel-High Lock indicator light will ﬂash for 15 seconds but will not complete the shift unless your vehicle is moving less than 3 mph (5 km/h) and the transmission is in NEUTRAL (N). Shifting Into NEUTRAL To shift the transfer case to NEUTRAL, do the following: 1. Set the parking brake. 2. Start the vehicle by turning the ignition to START. 3. Put the transmission in NEUTRAL (N). If your vehicle has a manual transmission, press and hold the clutch pedal down while you perform Steps 5 through 9. 4. Shift the transfer case to Four-Wheel High. {CAUTION: Shifting an all-wheel-drive vehicle’s transfer case into NEUTRAL can cause your vehicle to roll even if the automatic transmission is in PARK (P) or the manual transmission is in any gear. You or others could be injured. Make sure the parking brake is ﬁrmly set before you shift the transfer case to NEUTRAL. 114 5. Simultaneously press and hold the Four-Wheel High and Four-Wheel-Low Lock buttons for 10 seconds. The NEUTRAL light will come on when the transfer case shift to NEUTRAL is complete. 6. Press and hold the regular brake pedal and Shift the transmission to REVERSE (R) for one second, then shift the transmission for one second to DRIVE (D) for an automatic transmission, or FIRST (1) for vehicles have a manual transmission and then let out the clutch. This is to ensure the transfer case is in NEUTRAL. If not, repeat this procedure starting at Step 3. 7. Turn the engine off, by turning the key to ACC. 8. Place the transmission shift lever in PARK (P) for an automatic transmission, or FIRST (1) for vehicles that have a manual transmission. 9. Turn the ignition to LOCK. Shifting Out of NEUTRAL To shift out of NEUTRAL: 1. Set the parking brake and apply the regular brake pedal. 2. Shift the transmission to NEUTRAL (N) for an automatic transmission, or press the clutch pedal for vehicles that have a manual transmission. Then turn the ignition to ON with the engine off. 3. Press the button for the desired transfer case shift position (Four-Wheel High, Four-Wheel-High Lock or Four-Wheel-Low Lock). After the transfer case has shifted out of NEUTRAL the light will go out. 4. Release the parking brake. Notice: Shifting the transmission into gear before the indicator light stops ﬂashing could cause damage to the transfer case. Always wait until the indicator light stops ﬂashing before putting the transmission back in gear. 5. You may start the engine and shift the transmission to the desired position. 115 Parking Brake The parking brake pedal is located to the left of the regular brake pedal, near the driver’s door. To set the parking brake, hold the regular brake pedal down with your right foot. Push the parking brake pedal down to its fully-applied position with your left foot. A chime will activate and the brake warning light, located on the instrument panel, will ﬂash when the parking brake is applied and the vehicle is moving at least 3 mph (5 km/h) for at least three seconds. The chime will deactivate and the light will turn off when the parking brake is set and the vehicle is moving below 3 mph (5 km/h). See Brake System Warning Light on page 182. 116 To release the parking brake, hold the regular brake pedal down. Pull the bottom edge of the lever, located above the parking brake pedal, with the parking brake symbol, directly rearward to release the parking brake. If the ignition is on when the parking brake is released, the brake system warning light will go off. Notice: Driving with the parking brake on can overheat the brake system and cause premature wear or damage to brake system parts. Verify that the parking brake is fully released and the brake warning light is off before driving. If you are towing a trailer and are parking on any hill, see Towing a Trailer on page 297. Shifting Into Park (P) (Automatic Transmission) {CAUTION: {CAUTION: It can be dangerous to get out of your vehicle if the shift lever is not fully in PARK (P) with the parking brake ﬁrmly set. Your vehicle can roll. If you have left the engine running, the vehicle can move suddenly. You or others could be injured. To be sure your vehicle will not move, even when you are on fairly level ground, use the steps that follow. If you are pulling a trailer, see Towing a Trailer on page 297. 1. Hold the brake pedal down with your right foot and set the parking brake. With all-wheel drive, your vehicle will be free to roll — even if your shift lever is in PARK (P) — if your transfer case is in NEUTRAL. So, be sure the transfer case is in a drive gear, four-wheel high (4H) or four-wheel low (4L) — not in NEUTRAL. 2. Move the shift lever into PARK (P) by pressing the shift lever button and moving the lever as far forward as it will go. 3. Turn the ignition key to LOCK. 4. Remove the key and take it with you. If you can leave your vehicle with the key, your vehicle is in PARK (P). 117 Torque Lock (Automatic Transmission) If you are parking on a hill and you do not shift your transmission into PARK (P) 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 PARK (P). This is called “torque lock.” To prevent torque lock, set the parking brake and then shift into PARK (P) properly before you leave the driver’s seat. To ﬁnd out how, see Shifting Into Park (P) (Automatic Transmission) on page 117. When you are ready to drive, move the shift lever out of PARK (P) 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 PARK (P). Leaving Your Vehicle With the Engine Running (Automatic Transmission) {CAUTION: It can be dangerous to leave your vehicle with the engine running. Your vehicle could move suddenly if the shift lever is not fully in PARK (P) 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 your vehicle with the engine running. If you have to leave your vehicle with the engine running, be sure your vehicle is in PARK (P) and your parking brake is ﬁrmly set before you leave it. After you have moved the shift lever into PARK (P), hold the regular brake pedal down. Then, see if you can move the shift lever away from PARK (P) without ﬁrst pressing the shift lever button. If you can, it means that the shift lever was not fully locked into PARK (P). 118 Shifting Out of Park (P) (Automatic Transmission) Your vehicle has an automatic transmission shift lock control system. You have to apply your regular brake before you can shift from PARK (P) when the ignition is in ON. See Automatic Transmission Operation on page 106. If you cannot shift out of PARK (P), ease pressure on the shift lever and push the shift lever all the way into PARK (P) as you maintain brake application. Then move the shift lever into the gear you wish. Press the shift lever button before moving the shift lever. Parking Your Vehicle (Manual Transmission) Your vehicle has a manual transmission. Before you get out of your vehicle, move the shift lever into REVERSE (R), and ﬁrmly apply the parking brake. Once the shift lever has been placed into REVERSE (R) with the clutch pedal pressed in, turn the ignition key to LOCK, remove the key and release the clutch. If you are parking on a hill, or if your vehicle is pulling a trailer, see Towing a Trailer on page 297. Parking Over Things That Burn {CAUTION: Things that can burn could touch hot exhaust parts under your vehicle and ignite. Do not park over papers, leaves, dry grass, or other things that can burn. 119 CAUTION: (Continued) (cid:127) Your vehicle was damaged when driving over high points on the road or over road debris. (cid:127) Repairs were not done correctly. (cid:127) Your vehicle or exhaust system has been modiﬁed improperly. If you ever suspect exhaust is coming into your vehicle: (cid:127) Drive it only with all the windows down to blow out any CO; and (cid:127) Have your vehicle ﬁxed immediately. Engine Exhaust {CAUTION: Engine exhaust can kill. It contains the gas carbon monoxide (CO), which you cannot see or smell. It can cause unconsciousness and death. You might have exhaust coming in if: (cid:127) Your exhaust system sounds strange or different. (cid:127) Your vehicle gets rusty underneath. (cid:127) Your vehicle was damaged in a collision. CAUTION: (Continued) 120 Running the Engine While Parked It is better not to park with the engine running. But if you ever have to, here are some things to know. {CAUTION: Idling the engine with the climate control system off could allow dangerous exhaust into your vehicle. See the earlier caution under Engine Exhaust on page 120. Also, idling in a closed-in place can let deadly carbon monoxide (CO) into your vehicle even if the climate control fan is at the highest setting. One place this can happen is a garage. Exhaust — with CO — can come in easily. NEVER park in a garage with the engine running. Another closed-in place can be a blizzard. See Winter Driving on page 281. {CAUTION: It can be dangerous to get out of your vehicle if the automatic transmission shift lever is not fully in PARK (P) with the parking brake ﬁrmly set. Your vehicle can roll. Do not leave your 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 your vehicle will not move, even when it is on fairly level ground, always set the parking brake and move the automatic transmission shift lever to PARK (P), or the manual transmission shift lever to NEUTRAL. Follow the proper steps to be sure your vehicle will not move. See Shifting Into Park (P) (Automatic Transmission) on page 117 and Parking Your Vehicle (Manual Transmission) on page 119. If you are pulling a trailer with your vehicle, see Towing a Trailer on page 297. 121 Mirrors Automatic Dimming Rearview Mirror with OnStar®, Compass and Temperature Display Your vehicle may have this feature. When on, the automatic dimming mirror dims to the proper level to minimize glare from lights behind you after dark. The mirror has a dual display in the upper right corner of the mirror face that shows the compass reading and the outside temperature. Control buttons for the OnStar® system are at the bottom of the mirror. See OnStar® System on page 129 for more information about the services OnStar® provides. P(On/Off): This is the on/off button. Temperature and Compass Display Press the on/off button, located to the far left, brieﬂy to turn the compass/temperature display on or off. If the display reads CAL, the compass needs to be calibrated. For more information, see “Compass Calibration” following. To adjust between Fahrenheit and Celsius, do the following: 1. Press and hold the on/off button for approximately four seconds until either a ﬂashing F or C appears. 2. Press the button again to change the display to the desired unit of measurement. After approximately four seconds of inactivity, the new unit will be locked in and the compass/temperature display will return. If an abnormal temperature reading is displayed for an extended period of time, see your dealer.

Compass Calibration The compass may need calibration if one of the following occurs: (cid:127) After approximately ﬁve seconds, the display does not show a compass heading, N for North, for example, there may be a strong magnetic ﬁeld interfering with the compass. Such interference may be caused by a magnetic antenna mount, magnetic note pad holder, or a similar magnetic item. (cid:127) The compass does not display the correct heading and the compass zone variance is set correctly. In order to calibrate, CAL must be displayed in the mirror compass windows. If CAL is not displayed, push the on/off button for approximately 12 seconds or until CAL is displayed. The compass can be calibrated by driving the vehicle in circles at 5 mph (8 km/h) or less until the display reads a direction. 123 Compass Variance The mirror is set in zone eight upon leaving the factory. It will be necessary to adjust the compass to compensate for compass variance if the vehicle is outside of zone eight. Under certain circumstances, as during a long distance cross-country trip, it will be necessary to adjust for compass variance. Compass variance is the difference between earth’s magnetic north and true geographic north. If not adjusted to account for compass variance, the compass could give false readings. To adjust for compass variance, do the following: 1. Find your current location and variance zone number on the following zone map. 124 2. Press and hold the on/off button until a Z and a zone number appears in the display. The compass is now in zone mode. 3. Keep pressing the on/off button until the desired zone number appears in the display. Release the button.

When you use the Virtual Advisor feature of OnStar® Hands-Free Calling, your vehicle also sends OnStar® your GPS location so that we can provide you with location-based services. OnStar® service cannot work unless your vehicle is in a place where OnStar® has an agreement with a wireless service provider for service in that area. OnStar® service also cannot work unless you are in a place where the wireless service provider OnStar® has hired for that area has coverage, network capacity and reception when the service is needed, and technology that is compatible with the OnStar® service. Not all services are available everywhere, particularly in remote or enclosed areas, or at all times. 131 OnStar® service that involves location information about your vehicle cannot work unless GPS satellite signals are unobstructed and available in that place as well. Your vehicle must have a working electrical system (including adequate battery power) for the OnStar® equipment to operate. There are other problems OnStar® cannot control that may prevent OnStar® from providing OnStar® service to you at any particular time or place. Some examples are damage to important parts of your vehicle in an accident, hills, tall buildings, tunnels, weather or wireless phone network congestion. Your Responsibility You may need to increase the volume of your radio to hear the OnStar® advisor. If the light next to the OnStar® buttons is red, this means that your system is not functioning properly and should be checked by a dealer. If the light appears clear (no light is appearing), your OnStar® subscription has expired. You can always press the blue OnStar® button to conﬁrm that your OnStar® equipment is active.

Because of the steps involved, it may be helpful to have another person available to assist you in programming the transmitter. Be sure to keep the original remote control transmitter for use in other vehicles, as well as, for future programming. You only need the original remote control transmitter for ﬁxed code programming. It is also recommended that upon the sale or lease termination of the vehicle, the programmed buttons should be erased for security purposes. See “Erasing your Universal Home Remote Buttons” later in this section. Universal Home Remote System Operation (With Three Round LED) Your vehicle may have the Universal Home Remote System. If there are three round Light Emitting Diode (LED) above the Universal Home Remote System buttons, follow the instructions below. If there is one triangular LED above the Universal Home Remote System buttons, follow the instructions under Universal Home Remote System Operation (with one triangular LED). 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 lighting. 134 Be sure that people and objects are clear of the garage door or security device you are programming. When programming a garage door, it is advised to park outside of the garage. Your garage door opener is a ﬁxed code device if there is a panel of switches. If not, your garage door opener is a rolling code device. Programming Universal Home Remote — Fixed Code Fixed Code garage door openers are used for garage doors produced prior to 1996. Fixed code uses the same coded signal every time, which is manually programmed by setting DIP switches for a unique personal code. If you do not know if your garage door opener is a ﬁxed code or rolling code device, open your garage door opener’s remote control battery cover. 135 To program up to three channels, 1. Remove the battery cover of the hand-held transmitter. 3. Enter these positions into the Universal Home Remote System as follows. Press and release all three buttons at the same time to put the device into programming mode. Example of Switch Settings 2. Write down the eight to 12 coding switch settings from left to right. When the switch is in the up position, write “on,” and when a switch is in the down position, write “off”. If a switch is set between the up and down position, write “middle”. 136 4. The indicator light will blink slowly. In order from left to right, and within two and one-half minutes, enter each switch setting into the Universal Home Remote System. Push one button for each switch as follows: (cid:127) Left button = “on” switch position. (cid:127) Right button = “off” switch position. (cid:127) Middle button = “middle” switch position. 5. After entering the switch settings, press and release all three buttons at the same time. The indicator lights will turn on. 6. Press and hold the button you would like to use to control the garage door until the garage door moves. The indicator light above the selected button should slowly blink. You may need to hold the button from ﬁve to 55 seconds. 7. Immediately release the button when the garage door moves. The indicator light will blink rapidly until programming is complete. 8. Press and release the button again. The garage door should move, conﬁrming that programming is successful and complete. To program another device such as an additional garage door opener, a security device, or home lighting, repeat Steps 1–8, choosing a different function button in Step 7 than what you used for the garage door opener. Programming Universal Home Remote — Rolling Code Rolling code garage door openers are used for garage doors produced after 1996 and are code protected. Rolling code means the coded signal is changed every time your remote control garage door opener is used. Programming a rolling code garage door opener involves time-sensitive actions, so read the entire procedure before you begin. If you do not follow these actions, the device will time out and you will have to repeat the procedure. Follow these steps to program up to three channels: 1. Press the two outside buttons at the same time for one to two seconds, and immediately release them. 137 3. Press and hold the button you would like to use to control the garage door until the garage door moves. The indicator light, above the selected button, should slowly blink. You may need to hold the button from ﬁve to 20 seconds. 4. Immediately release the button when the garage door moves. The indicator light will blink rapidly until programming is complete. 5. Press and release the button again. The garage door should move, conﬁrming that programming is successful and complete. To program another device such as an additional garage door opener, a security device, or home lighting, repeat Steps 1–5, choosing a different function button in Step 3 than what you used for the garage door opener. Using Universal Home Remote Press and hold the appropriate button for at least half of a second. The indicator light will come on while the signal is being transmitted. 2. Go to the garage. Locate the garage door motor head and press and release the “learn” button. After pressing the “learn” button, you have 10 to 30 seconds to complete Step 4 depending on your garage control unit. If you cannot locate the “learn” button, refer to the owners guide for your garage door opener. 138 Reprogramming Universal Home Remote Buttons You can reprogram any of the three buttons by repeating the instructions. Erasing Universal Home Remote Buttons You should erase the programmed buttons when you sell the vehicle or terminate your lease. To erase either rolling code or ﬁxed code on the Universal Home Remote device, do the following: 1. Press and hold the two outside buttons at the same time for approximately 20 seconds, until the indicator lights, located directly above the buttons, begin to blink rapidly. 2. Once the indicator lights begin to blink, release both buttons. The codes from all button will be erased.
