When another track is added to the song list, the track is added to the end of the list. To delete the entire song list, perform the following steps: 1. Turn the CD player on. 2. Press the song list button to turn song list on. S-LIST displays. 3. Press and hold the song list button for more than four seconds. One beep sounds, followed by two beeps after two seconds, and a ﬁnal beep sounds after four seconds. S-LIST EMPTY displays indicating the song list has been deleted. If a CD is ejected, and the song list contains saved tracks from that CD, those tracks are automatically deleted from the song list. Any tracks saved to the song list again are added to the bottom of the list. To end song list mode, press the song list button. One beep sounds and S-LIST is removed from the display. 221 CD Messages CHECK CD: If this message appears on the display and/or the CD comes out, it could be for one of the following reasons: (cid:127) It is very hot. When the temperature returns to normal, the CD should play. (cid:127) You are driving on a very rough road. When the road becomes smoother, the CD should play. (cid:127) The CD is dirty, scratched, wet, or upside down. (cid:127) The air is very humid. If so, wait about an hour and try again. (cid:127) There may have been a problem while burning the CD. (cid:127) The label may be caught in the CD player. If the CD is not playing correctly, for any other reason, try a known good CD. If any error occurs repeatedly or if an error cannot be corrected, contact your dealer. If the radio displays an error message, write it down and provide it to your dealer when reporting the problem. 222 Using an MP3 MP3 CD-R Disc MP3 Format If you burn your own MP3 disc on a personal computer: (cid:127) Make sure the MP3 ﬁles are recorded on a CD-R disc. (cid:127) Do not mix standard audio and MP3 ﬁles on one disc. (cid:127) Make sure playlists have a .mp3 or .wpl extension, other ﬁle extensions may not work. (cid:127) Files can be recorded with a variety of ﬁxed or variable bit rates. Song title, artist name, and album are available for display by the radio when recorded using ID3 tags version 1 and 2. (cid:127) Create a folder structure that makes it easy to ﬁnd songs while driving. Organize songs by albums using one folder for each album. Each folder or album should contain 18 songs or less. (cid:127) Make sure to ﬁnalize the disc when burning an MP3 disc, using multiple sessions. It is usually better to burn the disc all at once. The player will be able to read and play a maximum of 50 folders, 50 playlists, 10 sessions, and 255 ﬁles. Long ﬁle names, folder names, or playlist names may use more disc memory space than necessary. To conserve space on the disc, minimize the length of the ﬁle, folder, or playlist names. You can also play an MP3 CD that was recorded using no ﬁle folders. The system can support up to 11 folders in depth, though, keep the depth of the folders to a minimum in order to keep down the complexity and confusion in trying to locate a particular folder during playback. If a CD contains more than the maximum of 50 folders, 50 playlists, 10 sessions, and 255 ﬁles the player lets you access and navigate up to the maximum, but all items over the maximum are ignored. Root Directory The root directory is treated as a folder. If the root directory has compressed audio ﬁles, the directory is displayed as F1 ROOT. All ﬁles contained directly under the root directory are accessed prior to any root directory folders. However, playlists (Px) are always accessed before root folders or ﬁles. Empty Directory or Folder If a root directory or a folder exists somewhere in the ﬁle structure that contains only folders/ subfolders and no compressed ﬁles directly beneath them, the player advances to the next folder in the ﬁle structure that contains compressed audio ﬁles. The empty folder does not display. No Folder When the CD contains only compressed ﬁles, the ﬁles are located under the root folder. The next and previous folder functions does not function on a CD that was recorded without folders or playlists. When displaying the name of the folder the radio displays ROOT. When the CD contains only playlists and compressed audio ﬁles, but no folders, all ﬁles are located under the root folder. The folder down and the folder up buttons search playlists (Px) ﬁrst and then go to the root folder. When the radio displays the name of the folder the radio displays ROOT. 223 Order of Play Tracks are played in the following order: (cid:127) Play begins from the ﬁrst track in the ﬁrst playlist and continues sequentially through all tracks in each playlist. When the last track of the last playlist has played, play continues from the ﬁrst track of the ﬁrst playlist. If the CD does not contain any playlists, then play begins from the ﬁrst track under the root directory. When all tracks from the root directory have played, play continues from ﬁles according to their numerical listing. After playing the last track from the last folder, play begins again at the ﬁrst track of the ﬁrst folder or root directory. (cid:127) When play enters a new folder, the display does not automatically show the new folder name unless the folder mode has been chosen as the default display. See DISP (display) later in this section for more information. The new track name appears on the display. 224 File System and Naming The song name that is displayed is the song name that is contained in the ID3 tag. If the song name is not present in the ID3 tag, the radio displays the ﬁle name without the extension (such as .mp3) as the track name. Track names longer than 32 characters or 4 pages are shortened. Parts of words on the last page of text and the extension of the ﬁlename does not display. Preprogrammed Playlists Preprogrammed playlists that were created using WinAmp™, MusicMatch™, or Real Jukebox™ software can be accessed, however, they cannot be edited using the radio. These playlists are treated as special folders containing compressed audio song ﬁles. Playing an MP3 Insert a CD partway into the slot, label side up. The player pulls it in, and READING displays. The CD should begin playing and the CD symbol appears on the display. If you want to insert a CD with the ignition off, ﬁrst press the eject button or the DISP knob. If the ignition or radio is turned off with a CD in the player it stays in the player. When the ignition or radio is turned on, the CD starts to play where it stopped, if it was the last selected audio source. As each new track starts to play, the track number appears on the display. The CD player can play the smaller 3 inch (8 cm) single CDs with an adapter ring. Full-size CDs and the smaller CDs are loaded in the same manner. If playing a CD-R, the sound quality may be reduced due to CD-R quality, the method of recording, the quality of the music that has been recorded, and the way the CD-R has been handled. There may be an increase in skipping, difficulty in ﬁnding tracks, and/or difficulty in loading and ejecting. If these problems occur, check the bottom surface of the CD. If the surface of the CD is damaged, such as cracked, broken, or scratched, the CD will not play properly. If the surface of the CD is soiled, see Care of Your CDs on page 231 for more information. If there is no apparent damage, try a known good CD. Do not add any label to a CD, it could get caught in the CD player. If a CD is recorded on a personal computer and a description label is needed, try labeling the top of the recorded CD with a marking pen. Notice: If you add any label to a CD, insert more than one CD into the slot at a time, or attempt to play scratched or damaged CDs, you could damage the CD player. When using the CD player, use only CDs in good condition without any label, load one CD at a time, and keep the CD player and the loading slot free of foreign materials, liquids, and debris. If an error appears on the display, see “CD Messages” later in this section. t SEEK u: Press the left arrow to go to the start of the previous track.

Theft lock active Radio ID Radio ID label (channel 0) Unknown Check XM Radio ID not known (should only be if hardware failure) Hardware failure The XM™ receiver in your vehicle may have previously been in another vehicle. For security purposes, XM™ receivers cannot be swapped between vehicles. If this message is received after having your vehicle serviced, check with your GM dealer. If tuned to channel 0, this message will alternate with the XM™ Radio eight digit radio ID label. This label is needed to activate the service. If this message is received when tuned to channel 0, there may be a receiver fault. Consult with your GM dealer. If this message does not clear within a short period of time, the receiver may have a fault. Consult with your GM dealer. 229 Navigation/Radio System Your vehicle may have a navigation radio system. The navigation system has built-in features intended to minimize driver distraction. Technology alone, no matter how advanced, can never replace your own judgment. See the Navigation System manual for some tips to help you reduce distractions while driving. Theft-Deterrent Feature THEFTLOCK® is designed to discourage theft of your vehicle’s radio. The feature works automatically by learning a portion of the Vehicle Identiﬁcation Number (VIN). If the radio is moved to a different vehicle, it does not operate and LOCKED displays. When the radio and vehicle are turned off, the blinking red light indicates that THEFTLOCK® is armed. With THEFTLOCK® activated, the radio does not operate if stolen. Radio Reception You may experience frequency interference and static during normal radio reception if items such as cellphone chargers, vehicle convenience accessories, and external electronic devices are plugged into the accessory power outlet. If there is interference or static, unplug the item from the accessory power outlet. AM The range for most AM stations is greater than for FM, especially at night. The longer range can cause station frequencies to interfere with each other. For better radio reception, most AM radio stations will boost the power levels during the day, and then reduce these levels during the night. Static can also occur when things like storms and power lines interfere with radio reception. When this happens, try reducing the treble on your radio. 230 FM Stereo FM stereo will give the best sound, but FM signals will reach only about 10 to 40 miles (16 to 65 km). Tall buildings or hills can interfere with FM signals, causing the sound to fade in and out. XM™ Satellite Radio Service XM™ Satellite Radio Service gives digital radio reception from coast-to-coast in the 48 contiguous United States, and in Canada. Just as with FM, tall buildings or hills can interfere with satellite radio signals, causing the sound to fade in and out. In addition, traveling or standing under heavy foliage, bridges, garages, or tunnels may cause loss of the XM™ signal for a period of time. The radio may display No Signl to indicate interference. Care of Your CDs Handle CDs carefully. Store them in their original cases or other protective cases and away from direct sunlight and dust. The CD player scans the bottom surface of the disc. If the surface of a CD is damaged, such as cracked, broken, or scratched, the CD will not play properly or not at all. If the surface of a CD is soiled, take a soft, lint free cloth or dampen a clean, soft cloth in a mild, neutral detergent solution mixed with water, and clean it. Make sure the wiping process starts from the center to the edge. Do not touch the bottom side of a CD while handling it; this could damage the surface. Pick up CDs by grasping the outer edges or the edge of the hole and the outer edge. 231 Care of the CD Player Do not use CD lens cleaners for CD players because the lens of the CD optics can become contaminated by lubricants. Fixed Mast Antenna The ﬁxed mast antenna can withstand most car washes without being damaged. If the mast should ever become slightly bent, straighten it out by hand. If the mast is badly bent, replace it. Check occasionally to make sure the mast is still tightened to the fender. If tightening is required, tighten by hand, then with a wrench one quarter turn. XM™ Satellite Radio Antenna System The XM™ Satellite Radio antenna is located on the roof of your vehicle. Keep this antenna clear of snow and ice build up for clear radio reception. If your vehicle has a sunroof, the performance of the XM™ system may be affected if the sunroof is open. Loading items onto the roof of your vehicle can interfere with the performance of the XM™ system. Make sure the XM™ Satellite Radio antenna is not obstructed. 232 Section 4 Driving Your Vehicle Your Driving, the Road, and Your Vehicle .... 234 Defensive Driving ...................................... 234 Drunken Driving ........................................ 235 Control of a Vehicle .................................. 238 Braking ...................................................... 238 Anti-Lock Brake System (ABS) .................. 239 Braking in Emergencies ............................. 241 Traction Control System (TCS) .................. 241 Locking Rear Axle ..................................... 243 StabiliTrak® System ................................... 244 Steering .................................................... 245 Off-Road Recovery .................................... 247 Passing ..................................................... 247 Loss of Control .......................................... 249 Off-Road Driving ........................................ 250 Assist Steps .............................................. 271 Driving at Night ......................................... 272 Driving in Rain and on Wet Roads ............ 273 City Driving ............................................... 276 Freeway Driving ........................................ 277 Before Leaving on a Long Trip .................. 278 Highway Hypnosis ..................................... 279 Hill and Mountain Roads ........................... 279 Winter Driving ........................................... 281 If Your Vehicle is Stuck in Sand, Mud, Ice, or Snow ................................. 286 Rocking Your Vehicle to Get It Out ........... 286 Recovery Loops ........................................ 287 Loading Your Vehicle ................................ 289 Towing ........................................................ 294 Towing Your Vehicle ................................. 294 Recreational Vehicle Towing ...................... 295 Towing a Trailer ........................................ 297 Trailer Recommendations .......................... 310 233 Your Driving, the Road, and Your Vehicle {CAUTION: Defensive Driving The best advice anyone can give about driving is: Drive defensively. Please start with a very important safety device in your vehicle: Buckle up. See Safety Belts: They Are for Everyone on page 17. Defensive driving really means “Be ready for anything.” On city streets, rural roads, or expressways, it means “Always expect the unexpected.” Assume that pedestrians or other drivers are going to be careless and make mistakes. Anticipate what they might do and be ready. Rear-end collisions are about the most preventable of accidents. Yet they are common. Allow enough following distance. Defensive driving requires that a driver concentrate on the driving task. Anything that distracts from the driving task makes proper defensive driving more difficult and can even cause a collision, with resulting injury. Ask a passenger to help do these things, or pull off the road in a safe place to do them. These simple defensive driving techniques could save your life. 234 Drunken Driving Death and injury associated with drinking and driving is a national tragedy. It is the number one contributor to the highway death toll, claiming thousands of victims every year. Alcohol affects four things that anyone needs to drive a vehicle: (cid:127) Judgment (cid:127) Muscular Coordination (cid:127) Vision (cid:127) Attentiveness Police records show that almost half of all motor vehicle-related deaths involve alcohol. In most cases, these deaths are the result of someone who was drinking and driving. In recent years, more than 16,000 annual motor vehicle-related deaths have been associated with the use of alcohol, with more than 300,000 people injured. Many adults — by some estimates, nearly half the adult population — choose never to drink alcohol, so they never drive after drinking. For persons under 21, it is against the law in every U.S. state to drink alcohol. There are good medical, psychological, and developmental reasons for these laws. The obvious way to eliminate the leading highway safety problem is for people never to drink alcohol and then drive. But what if people do? How much is “too much” if someone plans to drive? It is a lot less than many might think. Although it depends on each person and situation, here is some general information on the problem. The Blood Alcohol Concentration (BAC) of someone who is drinking depends upon four things: (cid:127) The amount of alcohol consumed (cid:127) The drinker’s body weight (cid:127) The amount of food that is consumed before and during drinking (cid:127) The length of time it has taken the drinker to consume the alcohol 235 According to the American Medical Association, a 180 lb (82 kg) person who drinks three 12 ounce (355 ml) bottles of beer in an hour will end up with a BAC of about 0.06 percent. The person would reach the same BAC by drinking three 4 ounce (120 ml) glasses of wine or three mixed drinks if each had 1-1/2 ounces (45 ml) of liquors like whiskey, gin, or vodka. It is the amount of alcohol that counts. For example, if the same person drank three double martinis (3 ounces or 90 ml of liquor each) within an hour, the person’s BAC would be close to 0.12 percent. A person who consumes food just before or during drinking will have a somewhat lower BAC level. There is a gender difference, too. Women generally have a lower relative percentage of body water than men. Since alcohol is carried in body water, this means that a woman generally will reach a higher BAC level than a man of her same body weight will when each has the same number of drinks. The law in most U.S. states, and throughout Canada, sets the legal limit at 0.08 percent. In some other countries, the limit is even lower. For example, it is 0.05 percent in both France and Germany. The BAC limit for all commercial drivers in the United States is 0.04 percent. The BAC will be over 0.10 percent after three to six drinks (in one hour). Of course, as we have seen, it depends on how much alcohol is in the drinks, and how quickly the person drinks them. 236 But the ability to drive is affected well below a BAC of 0.10 percent. Research shows that the driving skills of many people are impaired at a BAC approaching 0.05 percent, and that the effects are worse at night. All drivers are impaired at BAC levels above 0.05 percent. Statistics show that the chance of being in a collision increases sharply for drivers who have a BAC of 0.05 percent or above. A driver with a BAC level of 0.06 percent has doubled his or her chance of having a collision. At a BAC level of 0.10 percent, the chance of this driver having a collision is 12 times greater; at a level of 0.15 percent, the chance is 25 times greater! The body takes about an hour to rid itself of the alcohol in one drink. No amount of coffee or number of cold showers will speed that up. “I will be careful” is not the right answer. What if there is an emergency, a need to take sudden action, as when a child darts into the street? A person with even a moderate BAC might not be able to react quickly enough to avoid the collision. There is something else about drinking and driving that many people do not know. Medical research shows that alcohol in a person’s system can make crash injuries worse, especially injuries to the brain, spinal cord, or heart. This means that when anyone who has been drinking — driver or passenger — is in a crash, that person’s chance of being killed or permanently disabled is higher than if the person had not been drinking. {CAUTION: Drinking and then driving is very dangerous. Your reﬂexes, perceptions, attentiveness, and judgment can be affected by even a small amount of alcohol. You can have a serious — or even fatal — collision if you drive after drinking. Please do not drink and drive or ride with a driver who has been drinking. Ride home in a cab; or if you are with a group, designate a driver who will not drink. 237 Control of a Vehicle You have three systems that make your vehicle go where you want it to go. They are the brakes, the steering, and the accelerator. All three systems have to do their work at the places where the tires meet the road. Sometimes, as when you are driving on snow or ice, it is easy to ask more of those control systems than the tires and road can provide. That means you can lose control of your vehicle. See Traction Control System (TCS) on page 241. Adding non-GM accessories can affect your vehicle’s performance. See Accessories and Modiﬁcations on page 314. 238 Braking See Brake System Warning Light on page 182. Braking action involves perception time and reaction time. First, you have to decide to push on the brake pedal. That is perception time. Then you have to bring up your foot and do it. That is reaction time. Average reaction time is about three-fourths of a second. But that is only an average. It might be less with one driver and as long as two or three seconds or more with another. Age, physical condition, alertness, coordination, and eyesight all play a part. So do alcohol, drugs, and frustration. But even in three-fourths of a second, a vehicle moving at 60 mph (100 km/h) travels 66 feet (20 m). That could be a lot of distance in an emergency, so keeping enough space between your vehicle and others is important. And, of course, actual stopping distances vary greatly with the surface of the road, whether it is pavement or gravel; the condition of the road, whether it is wet, dry, or icy; tire tread; the condition of the brakes; the weight of the vehicle; and the amount of brake force applied. Avoid needless heavy braking. Some people drive in spurts — heavy acceleration followed by heavy braking — rather than keeping pace with traffic. This is a mistake. The brakes may not have time to cool between hard stops. The brakes will wear out much faster if you do a lot of heavy braking. If you keep pace with the traffic and allow realistic following distances, you will eliminate a lot of unnecessary braking. That means better braking and longer brake life. If your vehicle ever loses electrical power while you are driving, brake normally but do not pump the brakes. If you do, the pedal may get harder to push down. If your vehicle loses electrical power, you will still have some power brake assist. But you will use it when you brake. Once the power assist is used up, it may take longer to stop, the brake pedal will be harder to push, and you may experience longer pedal travel. Adding non-GM accessories can affect your vehicle’s performance. See Accessories and Modiﬁcations on page 314 Anti-Lock Brake System (ABS) Your vehicle has the Anti-Lock Brake System (ABS), an advanced electronic braking system that will help prevent a braking skid. When you start your engine and begin to drive away, ABS will check itself. You may hear a momentary motor or clicking noise while this test is going on. This is normal. If there is a problem with ABS, this warning light will stay on. See Anti-Lock Brake System Warning Light on page 183. 239 ABS can change the brake pressure faster than any driver could. The computer is programmed to make the most of available tire and road conditions. This can help you steer around the obstacle while braking hard. Let us say the road is wet and you are driving safely. Suddenly, an animal jumps out in front of you. You slam on the brakes and continue braking. Here is what happens with ABS: A computer senses that wheels are slowing down. If one of the wheels is about to stop rolling, the computer will separately work the brakes at each wheel. 240 As you brake, your computer keeps receiving updates on wheel speed and controls braking pressure accordingly. Remember: ABS does not change the time you need to get your foot up to the brake pedal or always decrease stopping distance. If you get too close to the vehicle in front of you, you will not have time to apply your brakes if that vehicle suddenly slows or stops. Always leave enough room up ahead to stop, even though you have ABS. Using ABS Do not pump the brakes. Just hold the brake pedal down ﬁrmly and let anti-lock work for you. You may feel the brakes vibrate, or you may notice some noise, but this is normal. Braking in Emergencies With ABS, you can steer and brake at the same time. In many emergencies, steering can help you more than even the very best braking. Traction Control System (TCS) Your vehicle has a Traction Control System (TCS) that limits wheel spin. This is especially useful in slippery road conditions. The system operates only if it senses that any of the wheels are spinning or beginning to lose traction. When this happens, the system applies the brakes to limit wheel spin and also reduces engine power. You may feel or hear the system working, but this is normal. The Traction Control System may operate on dry roads under some conditions. When this happens, you may notice a reduction in acceleration or a pumping sound. This is normal and doesn’t mean there’s a problem with your vehicle. Examples of these conditions include hard acceleration in a turn, an abrupt upshift or downshift of the transmission or driving on rough roads. If your vehicle is in cruise control when the TCS begins to limit wheel spin, the cruise control will automatically disengage. When road conditions allow you to safely use it again, you may re-engage the cruise control. See Cruise Control on page 159. 241 If your vehicle has a Driver information Center (DIC), a TRACTION FAILED message will appear when a Traction Control System or Anti-Lock Brake System problem has been detected and the vehicle needs service. See DIC Warnings and Messages on page 196 for more information. When this message is on, the system will not limit wheel spin. Adjust your driving accordingly. The traction control system automatically comes on whenever you start your vehicle. To limit wheel spin, especially in slippery road conditions, you should always leave the system on. But you can turn the traction control system off if you ever need to. To turn the system off, press and hold the TCS button for ﬁve seconds. This light will come on steady when the traction control system has been turned off. This light ﬂashes when TCS is active. If you press and hold the TC button for ﬁve seconds, the traction control system will turn off and a TRAC OFF message will appear on the DIC. Press the TC button again to turn the system back on. The TRAC OFF message will then go off. The traction control system will reset itself at each ignition cycle. Adding non-GM accessories can affect your vehicle’s performance. See Accessories and Modiﬁcations on page 314 for more information. 242 Locking Rear Axle Your vehicle may have this feature. The locking rear axle can give your vehicle additional traction from the rear wheels when traveling in off-road situations such as mud, snow, sand, steep hills and uneven terrain. The button used to turn this feature on or off is located to the right of the transfer case buttons on the center of the instrument panel. To lock the rear axle, do the following: 1. Place the transfer case in the 4LO Lock mode. This is the only mode which will allow the rear axle to lock. See Full-Time Four-Wheel Drive on page 111 for more information regarding the transfer case and 4LO Lock mode. 2. Press the button with the vehicle stopped or moving less than 2 mph (3 km/h). You must wait for the light in the button to stop ﬂashing and remain illuminated before the rear axle is locked. If you try to lock the rear axle while Notice: your vehicle is stuck and the tires are spinning, you could damage your vehicle’s drivetrain. The repairs would not be covered by your warranty. Always lock the rear axle before attempting situations and/or navigating terrain which could possibly cause the vehicle to become stuck. The locking rear axle will be disengaged when the wheel speed is greater than 20 mph (32 km/h), if the vehicle’s battery is low and/or the transfer case is shifted out of 4LO Lock mode. Notice: on pavement, you could damage your vehicle’s drivetrain. The repairs would not be covered by your warranty. Do not use the locking rear axle on pavement. If you need four-wheel drive when traveling on pavement, use only 4HI. If you lock the rear axle while driving 243 StabiliTrak® System Your vehicle has a vehicle stability enhancement system called StabiliTrak®. It is an advanced computer controlled system that assists you with directional control of the vehicle in difficult driving conditions. StabiliTrak® activates when the computer senses a discrepancy between your intended path and the direction the vehicle is actually traveling. StabiliTrak® selectively applies braking pressure at any one of the vehicle’s brakes to assist the driver with keeping the vehicle on the intended path. When you ﬁrst start your vehicle and begin to drive away, the system performs several diagnostic checks to insure there are no problems. You may hear or feel the system working. This is normal and does not mean there is a problem with your vehicle. If there is a problem detected with StabiliTrak®, a SERVICE STAB SYS message will be displayed on the Driver Information Center (DIC). See DIC Warnings and Messages on page 196 for more information. When this message is displayed, the system is not operational. Adjust your driving accordingly. 244 StabiliTrak® comes on automatically whenever you start your vehicle. However, when the transfer case is placed in Four-Wheel-Low Lock mode, StabiliTrak® is automatically disabled. See Full-Time Four-Wheel Drive on page 111 for more information. To help assist you with directional control of the vehicle, you should always leave the system on. You can turn StabiliTrak® off if you ever need to using the TC (traction control) on/off button. If you press and hold the TC button for ﬁve seconds, the StabiliTrak® system and the traction control system will turn off. When this is done, the STAB SYS OFF message will be displayed on the DIC. Press the TC button again to turn StabiliTrak® back on. See Traction Control System (TCS) on page 241. If your vehicle is in cruise control when the StabiliTrak® activates, the cruise control will automatically disengage. When road conditions allow you to safely use it again, you may reengage the cruise control. See “ Cruise Control on page 159 for more information. Steering Power Steering If you lose power steering assist because the engine stops or the system is not functioning, you can steer but it will take much more effort. Steering Tips It is important to take curves at a reasonable speed. A lot of the “driver lost control” accidents mentioned on the news happen on curves. Here is why: Experienced driver or beginner, each of us is subject to the same laws of physics when driving on curves. The traction of the tires against the road surface makes it possible for the vehicle to change its path when you turn the front wheels. If there is no traction, inertia will keep the vehicle going in the same direction. If you have ever tried to steer a vehicle on wet ice, you will understand this. The traction you can get in a curve depends on the condition of your tires and the road surface, the angle at which the curve is banked, and your speed. While you are in a curve, speed is the one factor you can control. Suppose you are steering through a sharp curve. Then you suddenly accelerate. Both control systems — steering and acceleration — have to do their work where the tires meet the road. Adding the sudden acceleration can demand too much of those places. You can lose control. See Traction Control System (TCS) on page 241 and StabiliTrak® System on page 244. What should you do if this ever happens? Ease up on the accelerator pedal, steer the vehicle the way you want it to go, and slow down. Speed limit signs near curves warn that you should adjust your speed. Of course, the posted speeds are based on good weather and road conditions. Under less favorable conditions you will want to go slower. If you need to reduce your speed as you approach a curve, do it before you enter the curve, while your front wheels are straight ahead. Try to adjust your speed so you can “drive” through the curve. Maintain a reasonable, steady speed. Wait to accelerate until you are out of the curve, and then accelerate gently into the straightaway. Adding non-GM accessories can affect your vehicle’s performance. See Accessories and Modiﬁcations on page 314. 245 Steering in Emergencies There are times when steering can be more effective than braking. For example, you come over a hill and ﬁnd a truck stopped in your lane, or a car suddenly pulls out from nowhere, or a child darts out from between parked cars and stops right in front of you. You can avoid these problems by braking — if you can stop in time. But sometimes you cannot; there is not room. That is the time for evasive action — steering around the problem. Your vehicle can perform very well in emergencies like these. First apply your brakes. See Braking on page 238. It is better to remove as much speed as you can from a possible collision. Then steer around the problem, to the left or right depending on the space available. 246 An emergency like this requires close attention and a quick decision. If you are holding the steering wheel at the recommended 9 and 3 o’clock positions, you can turn it a full 180 degrees very quickly without removing either hand. But you have to act fast, steer quickly, and just as quickly straighten the wheel once you have avoided the object. The fact that such emergency situations are always possible is a good reason to practice defensive driving at all times and wear safety belts properly. Off-Road Recovery You may ﬁnd that your right wheels have dropped off the edge of a road onto the shoulder while you are driving. If the level of the shoulder is only slightly below the pavement, recovery should be fairly easy. Ease off the accelerator and then, if there is nothing in the way, steer so that your vehicle straddles the edge of the pavement. You can turn the steering wheel up to one-quarter turn until the right front tire contacts the pavement edge. Then turn your steering wheel to go straight down the roadway. Passing The driver of a vehicle about to pass another on a two-lane highway waits for just the right moment, accelerates, moves around the vehicle ahead, then goes back into the right lane again. A simple maneuver? Not necessarily! Passing another vehicle on a two-lane highway is a potentially dangerous move, since the passing vehicle occupies the same lane as oncoming traffic for several seconds. A miscalculation, an error in judgment, or a brief surrender to frustration or anger can suddenly put the passing driver face to face with the worst of all traffic accidents — the head-on collision. So here are some tips for passing: (cid:127) Drive ahead. Look down the road, to the sides, and to crossroads for situations that might affect your passing patterns. If you have any doubt whatsoever about making a successful pass, wait for a better time. 247 (cid:127) Watch for traffic signs, pavement markings, and lines. If you can see a sign up ahead that might indicate a turn or an intersection, delay your pass. A broken center line usually indicates it is all right to pass, providing the road ahead is clear. Never cross a solid line on your side of the lane or a double solid line, even if the road seems empty of approaching traffic. (cid:127) Do not get too close to the vehicle you want to pass while you are awaiting an opportunity. For one thing, following too closely reduces your area of vision, especially if you are following a larger vehicle. Also, you will not have adequate space if the vehicle ahead suddenly slows or stops. Keep back a reasonable distance. (cid:127) When it looks like a chance to pass is coming up, start to accelerate but stay in the right lane and do not get too close. Time your move so you will be increasing speed as the time comes to move into the other lane. If the way is clear to pass, you will have a running start that more than makes up for the distance you would lose by dropping back. And if something happens to cause you to cancel your pass, you need only slow down and drop back again and wait for another opportunity. 248 (cid:127) If other vehicles are lined up to pass a slow vehicle, wait your turn. But take care that someone is not trying to pass you as you pull out to pass the slow vehicle. Remember to glance over your shoulder and check the blind spot. (cid:127) Check your vehicle’s mirrors, glance over your shoulder, and start your left lane change signal before moving out of the right lane to pass. When you are far enough ahead of the passed vehicle to see its front in your vehicle’s inside mirror, activate the right lane change signal and move back into the right lane. Remember that, if your vehicle’s passenger side outside mirror is convex, the vehicle you just passed may seem to be farther away from you than it really is. (cid:127) Try not to pass more than one vehicle at a time on two-lane roads. Reconsider before passing the next vehicle. (cid:127) Do not overtake a slowly moving vehicle too rapidly. Even though the brake lamps are not ﬂashing, it may be slowing down or starting to turn. If you are being passed, make it easy for the following driver to get ahead of you. Perhaps you can ease a little to the right. (cid:127) Loss of Control Let us review what driving experts say about what happens when the three control systems — brakes, steering, and acceleration — do not have enough friction where the tires meet the road to do what the driver has asked. In any emergency, do not give up. Keep trying to steer and constantly seek an escape route or area of less danger. Skidding In a skid, a driver can lose control of the vehicle. Defensive drivers avoid most skids by taking reasonable care suited to existing conditions, and by not overdriving those conditions. But skids are always possible. The three types of skids correspond to your vehicle’s three control systems. In the braking skid, your wheels are not rolling. In the steering or cornering skid, too much speed or steering in a curve causes tires to slip and lose cornering force. And in the acceleration skid, too much throttle causes the driving wheels to spin. A cornering skid is best handled by easing your foot off the accelerator pedal. Remember: Any traction control system helps avoid only the acceleration skid. If your traction system is off, then an acceleration skid is also best handled by easing your foot off the accelerator pedal. See Traction Control System (TCS) on page 241 and StabiliTrak® System on page 244. If your vehicle starts to slide, ease your foot off the accelerator pedal and quickly steer the way you want the vehicle to go. If you start steering quickly enough, your vehicle may straighten out. Always be ready for a second skid if it occurs. Of course, traction is reduced when water, snow, ice, gravel, or other material is on the road. For safety, you will want to slow down and adjust your driving to these conditions. It is important to slow down on slippery surfaces because stopping distance will be longer and vehicle control more limited. 249 While driving on a surface with reduced traction, try your best to avoid sudden steering, acceleration, or braking, including reducing vehicle speed by shifting to a lower gear. Any sudden changes could cause the tires to slide. You may not realize the surface is slippery until your vehicle is skidding. Learn to recognize warning clues — such as enough water, ice, or packed snow on the road to make a mirrored surface — and slow down when you have any doubt. Remember: Any Anti-Lock Brake System (ABS) helps avoid only the braking skid. Off-Road Driving This off-road guide is meant to provide advice for when you drive your vehicle off paved roads. Also, see Braking on page 238. Off-road driving can be great fun. But it does have some deﬁnite hazards. The greatest of these is the terrain itself. “Off-roading” means you have left the great North American road system behind. Traffic lanes are not marked. Curves are not banked. There are no road signs. Surfaces can be slippery, rough, uphill or downhill. In short, you have gone right back to nature. Off-road driving involves some new skills. And that is why it is very important that you read this guide. You will ﬁnd many driving tips and suggestions. These will help make your off-road driving safer and more enjoyable. Before You Go Off-Roading There are some things to do before you go out. For example, be sure to have all necessary maintenance and service work done. Check to make sure all underbody shields are properly attached. Make sure any equipment you may need — ﬁrst aid kit, cell phone, ﬂashlight, etc. — is securely stored in the vehicle. Be sure you read all the information about your four-wheel-drive vehicle in this manual. Is there enough fuel? Is the spare tire fully inﬂated? Are the ﬂuid levels up where they should be? What are the local laws that apply to off-roading where you will be driving? If you do not know, you should check with law enforcement people in the area. Will you be on someone’s private land? If so, be sure to get the necessary permission. 250 Loading Your Vehicle for Off-Road Driving {CAUTION: (cid:127) Cargo on the load ﬂoor piled higher than the seatbacks can be thrown forward during a sudden stop. You or your passengers could be injured. Keep cargo below the top of the seatbacks. (cid:127) Unsecured cargo on the load ﬂoor can be tossed about when driving over rough terrain. You or your passengers can be struck by ﬂying objects. Secure the cargo properly. (cid:127) Heavy loads on the roof raise the There are some important things to remember about how to load your vehicle. (cid:127) The heaviest things should be on the load ﬂoor and forward of your rear axle. Put heavier items in the rear area, as far forward as you can. (cid:127) Be sure the load is secured properly, so driving on the off-road terrain does not toss things around. You will ﬁnd other important information in this manual. See Loading Your Vehicle on page 289 and Tires on page 367. vehicle’s center of gravity, making it more likely to roll over. You can be seriously or fatally injured if the vehicle rolls over. Put heavy loads inside the cargo area, not on the roof. Keep cargo in the cargo area as far forward and low as possible. 251 Environmental Concerns Off-road driving can provide wholesome and satisfying recreation. However, it also raises environmental concerns. We recognize these concerns and urge every off-roader to follow these basic rules for protecting the environment: (cid:127) Always use established trails, roads, and areas that have been specially set aside for public off-road recreational driving; obey all posted regulations. (cid:127) Avoid any driving practice that could damage the environment — shrubs, ﬂowers, trees, grasses — or disturb wildlife. This includes wheel-spinning, breaking down trees, or unnecessary driving through streams or over soft ground. (cid:127) Always carry a litter bag — make sure all refuse is removed from any campsite before leaving. (cid:127) Take extreme care with open ﬁres (where permitted), camp stoves, and lanterns. (cid:127) Never park your vehicle over dry grass or other combustible materials that could catch ﬁre from the heat of the vehicle’s exhaust system. 252 Traveling to Remote Areas It makes sense to plan your trip, especially when going to a remote area. Know the terrain and plan your route. You are much less likely to get bad surprises. Get accurate maps of trails and terrain. Try to learn of any blocked or closed roads. It is also a good idea to travel with at least one other vehicle. If something happens to one of them, the other can help quickly. Does your vehicle have a winch? If so, be sure to read the winch instructions. In a remote area, a winch can be handy if you get stuck. But you will want to know how to use it properly. High Mobility Characteristics The HUMMER H3 has a 10 inch (25.4 cm) running ground clearance (A) and a 9 inch (22.8 cm) axle to ground clearance (B) while maintaining a low silhouette and a low center of gravity. The HUMMER H3 has an approximate approach angle (A) of 37.5 degrees and a departure angle (B) of 35.5 degrees, depending on suspension packages. 253 Also, your vehicle should be able to traverse a 40% (22 degrees) side slope at 6 mph (9.7 km/h) while fully loaded on high friction surfaces. Design speciﬁcations required a minimum gradeability of 60% (31 degrees) slope, with the vehicle fully loaded, on high friction surfaces with maximum vehicle speed not to exceed 6 mph (9.7 km/h). The vehicle is expected to traverse this grade only for short durations. Never stop and idle the vehicle or park it on this grade. 254
