vehicle. The air bag readiness light should ﬂash for a few seconds when you turn the ignition key to ON. If the light does not come on then, have it ﬁxed so it will be ready to warn you if there is a problem. 3-35 Air Bag Off Light When you turn the passenger’s air bag off, this light will come on and stay on to remind you that the air bag has been turned off. This light will go off when you turn the air bag back on again. See Air Bag Off Switch on page 1-46 for more on this, including important safety information. {CAUTION: If the passenger’s air bag is turned off for a person who isn’t in a risk group identiﬁed by the national government, that person won’t have the extra protection of an air bag. In a crash, the air bag wouldn’t be able to inﬂate and help protect the person sitting there. Don’t turn off the passenger’s air bag unless the person sitting there is in a risk group. See “Air Bag Off Switch” in the Index for more on this, including important safety information. 3-36 {CAUTION: If the air bag readiness light ever comes on when you have turned off the air bag, it means that something may be wrong with the air bag system. The passenger’s air bag could inﬂate even though the switch is off. If this ever happens, don’t let anyone whom the national government has identiﬁed as a member of a passenger air bag risk group sit in the passenger’s position (for example, don’t secure a rear-facing child restraint in your vehicle) until you have your vehicle serviced. See “Air Bag Off Switch” in the Index. Voltmeter Gage When the key is in ON with the engine not running, the voltmeter shows the voltage output of your battery. When the engine is running, it shows the voltage output of the charging system. The reading will change as the rate of charge changes (with engine speed, for example), but if the voltmeter reads at 9 volts or below, your instrument panel cluster and other systems may shut down. The Driver Information Center (DIC) will read LOW VOLTAGE when your vehicle is at 10 volts or below. Have it checked right away. Driving with the voltmeter reading at 10 volts or below could drain your battery and disable your vehicle. 3-37 Brake System Warning Light Your vehicle’s hydraulic brake system is divided into two parts. If one part is not working, the other part can still work and stop you. For good braking, though, you need both parts working well. This light should come on when you turn the ignition key to START. If it does not come on then, have it ﬁxed so it will be ready to warn you if there is a problem. If this warning light stays on after you start the engine, the parking brake may still be set or there could be a brake problem. Refer to Parking Brake on page 2-31 to see if it is set. If the parking brake is not set, have your brake system inspected right away. If the light comes on while you are driving and you have a LOW BRAKE FLUID message showing on the DIC, pull off the road and stop carefully. You may notice that the pedal is harder to push. Or, the pedal may go closer to the ﬂoor. It may take longer to stop. If the light is still on, have the vehicle towed for service. See Towing Your Vehicle on page 4-33. {CAUTION: Your brake system may not be working properly if the brake system warning light is on. Driving with the brake system warning light on can lead to an accident. If the light is still on after you have pulled off the road and stopped carefully, have the vehicle towed for service. 3-38 Anti-Lock Brake System Warning Light Traction Control System (TCS) Warning Light With the anti-lock brake system, the light will come on when your engine is started and may stay on for several seconds. That is normal. This light should come on brieﬂy as you start the engine. If the light does not come on then, have it ﬁxed so it will be ready to warn you if there is a problem. If the light stays on, turn the ignition to OFF. Or, if the light comes on when you are driving, stop as soon as possible and turn the ignition off. Then start the engine again to reset the system. If the light still stays on, or comes on again while you are driving, your vehicle needs service. If the regular brake system warning light is not on, you still have brakes, but you do not have anti-lock brakes. If the regular brake system warning light is also on, you do not have anti-lock brakes and there is a problem with your regular brakes. See Brake System Warning Light on page 3-38. Also see “Service ABS” under DIC Warnings and Messages on page 3-58. The anti-lock brake system warning light will come on brieﬂy when you turn the ignition key to ON. This is normal. If the light does not come on then, have it ﬁxed so it will be ready to warn you if there is a problem. If it stays on, or comes on and the DIC shows a SERVICE TRACTION SYSTEM message when you are driving, there is a problem with your TCS system and your vehicle needs service. When this light is on, the system will not limit wheel spin. Adjust your driving accordingly. If the driver turns off the Traction Control System by pressing the button on the console, the TCS system light will come on and the TRACTION SYSTEM OFF message will show on the DIC. 3-39 Active Handling System Light The Active Handling System light will come on brieﬂy as you start the engine. If the light does not come on then, have it ﬁxed so it will be ready to warn you if there is a problem. The light will also come on while the system warms up and the ACT HNDLING WARMING UP message will be displayed in the Driver Information Center (DIC). If the light stays on or comes on while you are driving, a chime sounds and a SERVICE ACTIVE HNDLG message appears on the DIC, there is a problem with your Active Handling System and your vehicle needs service. The driver can acknowledge this message by pressing the RESET button. When the SERVICE ACTIVE HNDLG message is displayed, the Active Handling System will not assist you in controlling the vehicle. You should have the system serviced as soon as possible. Adjust your driving accordingly. When the system is working, you will see the ACTIVE HANDLING message displayed in the DIC. You may also feel or hear the system working. This is normal. If the driver turns off the Active Handling System by pressing the button on the console, the Active Handling System light will come on, a chime will sound, and the TRAC/ACT HNDLG OFF message will be displayed in the DIC. The Traction Control System will also be turned off. See DIC Warnings and Messages on page 3-58 for more information. If the Active Handling System and the Traction Control System are off, pressing the console button momentarily will turn both systems on. The DIC will display the TRAC/ACT HNDLG ON message, the instrument cluster light will be off, and a chime will sound. See DIC Warnings and Messages on page 3-58 for more information. 3-40 Engine Coolant Temperature Gage Malfunction Indicator Lamp Check Engine Light United States Canada This gage shows the engine coolant temperature. If the gage pointer moves into the shaded area, your engine is too hot. This means that your engine coolant has overheated. If you have been operating your vehicle under normal driving conditions, you should pull off the road, stop your vehicle and turn off the engine as soon as possible. (The larger tic marks are in increments of 30° below 220°F (104°C) and in increments of 10° above 220°F (104°C).) See Engine Overheating on page 5-26 for more information. Your vehicle is equipped with a computer which monitors operation of the fuel, ignition and emission control systems. This system is called OBD II (On-Board Diagnostics- Second Generation) and is intended to assure that emissions are at acceptable levels for the life of the vehicle, helping to produce a cleaner environment. The CHECK ENGINE light comes on to indicate that there is a problem and service is required. Malfunctions often will be indicated by the system before any problem is apparent. This may prevent more serious damage to your vehicle. This system is also designed to assist your service technician in correctly diagnosing any malfunction. Notice: If you keep driving your vehicle with this light on, after a while, your emission controls may not work as well, your fuel economy may not be as good and your engine may not run as smoothly. This could lead to costly repairs that may not be covered by your warranty. 3-41 If the Light Is Flashing The following may prevent more serious damage to your vehicle: • Reducing vehicle speed. • Avoiding hard accelerations. • Avoiding steep uphill grades. If the light stops ﬂashing and remains on steady, see “If the Light Is On Steady” following. If the light continues to ﬂash, when it is safe to do so, stop the vehicle. Find a safe place to park your vehicle. Turn the key off, wait at least 10 seconds and restart the engine. If the light remains on steady, see “If the Light Is On Steady” following. If the light is still ﬂashing, follow the previous steps, and see your dealer for service as soon as possible. Notice: Modiﬁcations made to the engine, transmission, exhaust, intake or fuel system of your vehicle or the replacement of the original tires with other than those of the same Tire Performance Criteria (TPC) can affect your vehicle’s emission controls and may cause this light to come on. Modiﬁcations to these systems could lead to costly repairs not covered by your warranty. This may also result in a failure to pass a required Emission Inspection/Maintenance test. This light should come on, as a check to show you it is working, when the ignition is on and the engine is not running. If the light does not come on, have it repaired. This light will also come on during a malfunction in one of two ways: • Light Flashing — A misﬁre condition has been detected. A misﬁre increases vehicle emissions and may damage the emission control system on your vehicle. Diagnosis and service may be required. • Light On Steady — An emission control system malfunction has been detected on your vehicle. Diagnosis and service may be required. 3-42 If the Light Is On Steady You also may be able to correct the emission system malfunction by considering the following: Did you recently put fuel into your vehicle? If so, reinstall the fuel cap, making sure to fully install the cap. See Filling Your Tank on page 5-7. The diagnostic system can determine if the fuel cap has been left off or improperly installed. A loose or missing fuel cap will allow fuel to evaporate into the atmosphere. A few driving trips with the cap properly installed should turn the light off. Did you just drive through a deep puddle of water? If so, your electrical system may be wet. The condition will usually be corrected when the electrical system dries out. A few driving trips should turn the light off. Have you recently changed brands of fuel? If so, be sure to fuel your vehicle with quality fuel. See Gasoline Octane on page 5-4. Poor fuel quality will cause your engine not to run as efficiently as designed. You may notice this as stalling after start-up, stalling when you put the vehicle into gear, misﬁring, hesitation on acceleration or stumbling on acceleration. (These conditions may go away once the engine is warmed up.) This will be detected by the system and cause the light to turn on. If you experience one or more of these conditions, change the fuel brand you use. It will require at least one full tank of the proper fuel to turn the light off. If none of the above steps have made the light turn off, your dealer can check the vehicle. Your dealer has the proper test equipment and diagnostic tools to ﬁx any mechanical or electrical problems that may have developed. 3-43 Emissions Inspection and Maintenance Programs Some state/provincial and local governments have or may begin programs to inspect the emission control equipment on your vehicle. Failure to pass this inspection could prevent you from getting a vehicle registration. Here are some things you need to know to help your vehicle pass an inspection: Your vehicle will not pass this inspection if the CHECK ENGINE light is on or not working properly. Your vehicle will not pass this inspection if the OBD (on-board diagnostic) system determines that critical emission control systems have not been completely diagnosed by the system. The vehicle would be considered not ready for inspection. This can happen if you have recently replaced your battery or if your battery has run down. The diagnostic system is designed to evaluate critical emission control systems during normal driving. This may take several days of routine driving. If you have done this and your vehicle still does not pass the inspection for lack of OBD system readiness, your GM dealer can prepare the vehicle for inspection. 3-44 Engine Oil Pressure Gage United States Canada The engine oil pressure gage shows the engine oil pressure in psi (pounds per square inch) or kPa (kilopascals) when the engine is running. Oil pressure should be 20 to 80 psi (140 to 550 kPa). In certain situations such as long, extended idles on hot days, it could read as low as 6 psi (40 kPa) and still be considered normal. It may vary with engine speed, outside temperature and oil viscosity, but readings above the shaded area show the normal operating range. Readings in the shaded area tell you that the engine is low on oil, or that you might have some other oil problem. See Engine Oil on page 5-13. The engine oil pressure can also be displayed using the GAGES button on the Driver Information Center (DIC). See Driver Information Center (DIC) on page 3-48. Security Light {CAUTION: Do not keep driving if the oil pressure is low. If you do, your engine can become so hot that it catches ﬁre. You or others could be burned. Check your oil as soon as possible and have your vehicle serviced. Notice: Lack of proper engine oil maintenance may damage the engine. The repairs would not be covered by your warranty. Always follow the maintenance schedule in this manual for changing engine oil. This light comes on to remind you to arm your theft-deterrent system. If it comes on and stays on when your ignition is on, there may be a problem with your theft-deterrent system. See Theft-Deterrent System on page 2-16 and PASS-Key® on page 2-18. 3-45 Check Gages Warning Light Fuel Gage This light will come on brieﬂy when you are starting the engine. If the light comes on and stays on while you are driving, check your gages to see if they are in the warning areas. This light can come on for the following reasons: • Low Oil Pressure • High Coolant Temperature • High or Low Battery Voltage • Low Fuel Level Your fuel gage tells you about how much fuel you have left when the ignition is on. When the needle approaches the red zone, RESERVE FUEL will appear on the Driver Information Center (DIC) display. When the needle approaches the E, LOW FUEL will appear on the display. At this time, you still have a little fuel left, but you should get more soon. Press RESET to acknowledge a DIC message(s). Pressing RESET will also turn off a DIC message but the LOW FUEL message will come on again in 10 minutes if you have not added fuel to the vehicle. 3-46 Here are ﬁve things that some owners ask about. All these things are normal and do not indicate that anything is wrong with the fuel gage. • At the gas station, the gas pump shuts off before the gage reads F (full). • It takes more (or less) fuel to ﬁll up than the gage reads. For example, the gage reads half full, but it took more (or less) than half of the tank’s capacity to ﬁt it. • The gage pointer may move while cornering, braking or speeding up. • The gage may not indicate E (empty) when the ignition is turned off. • The gage reading may change slightly within the ﬁrst several minutes after starting the vehicle. You can use the Driver Information Center (DIC) to display more detailed fuel information. Each time you press FUEL, one of the following will appear in the Driver Information Center (DIC). • AVERAGE: The fuel economy calculated for the current tank of fuel, or since you last reset the display. • INST (Instant): The fuel economy calculated for your current driving conditions. • RANGE: The distance you can drive before refueling. You should reset the fuel information display every time you refuel. To reset the display, press FUEL until AVERAGE appears. Then, press RESET on the Driver Information Center (DIC). 3-47 Driver Information Center (DIC) The Driver Information Center (DIC) will display information about how your vehicle is functioning, as well as warning messages if a system problem is detected. The DIC display area is located in the instrument panel cluster below the speedometer and tachometer, directly above the steering column. The following buttons are located on the DIC control panel which is located to the right of the instrument panel cluster. 1 FUEL: Press this button to display fuel information such as fuel economy and range. 2 GAGES: Press this button to display gage information like oil pressure and temperature, coolant temperature, automatic transmission ﬂuid temperature (if equipped), battery voltage and front/rear tire pressures. 3 TRIP: Press this button to display your total and trip miles, the elapsed time function, your average speed and the engine oil life. 4 OPTIONS: This button allows you to choose personal options that are available on your vehicle, depending on the options your vehicle is equipped with, such as security, door locks, easy entry seats and language. 5 E/M (English/Metric): Press this button to change the display between English and metric units. RESET: This button, used along with the other buttons, will reset system functions and turn off or acknowledge messages on the Driver Information Center (DIC).

Be sure not to block the sensor or your lighting functions may be disrupted. 3-48 1 FUEL The FUEL button displays average fuel economy and instantaneous fuel economy calculated for your speciﬁc driving conditions and range. DIC Controls and Displays Turn on the system by turning the ignition to ON. When you turn on the ignition, the DIC will be in the mode last displayed when the engine was turned off. Each DIC button allows you to scroll through a menu. A blank page ends each menu. If a problem is detected, a diagnostic message will appear on the display. Press RESET to acknowledge any current warning or service messages. The following pages will show the messages you can see on the Driver Information Center (DIC) display by pressing the DIC buttons. Press the FUEL button to display average fuel economy, such as: • AVERAGE 20.1 MPG or • AVERAGE 5.3 L/100 km 3-49 The average fuel economy is viewed as a long-term approximation of your overall driving conditions. If you press RESET in this mode while you’re driving, the system will begin ﬁguring fuel economy from that point in time. Press FUEL again to display instantaneous fuel economy, such as: • INST. 20.1 MPG or • INST. 5.3 L/100 km Press FUEL again to display the range, such as: • RANGE 20 MI or • RANGE 32 km The range calculates the remaining distance you can drive without refueling. It’s based on fuel economy and the fuel remaining in the tank. If the range is lower than 30 miles (48 km), the display will read RANGE LOW. The fuel economy data used to determine fuel range is an average of recent driving conditions. As your driving conditions change, this data is gradually updated. Resetting the fuel range causes the fuel economy data to be updated immediately. Press RESET to reset the fuel range. 3-50 2 GAGES The GAGES button allows you to scroll through the functions listed below when you press it. Press the GAGE button to display the oil pressure, such as: • OIL PRESSURE 40 PSI or • OIL PRESSURE 276 kPa Press the GAGE button again to display the oil temperature, such as: • OIL TEMP 234°F or • OIL TEMP 112°C Press the GAGE button again to display the coolant temperature, such as: • COOLANT TEMP 123°F or • COOLANT TEMP 51°C Press the GAGE button again to display the automatic transmission ﬂuid temperature (if equipped), such as: • TRANS FLUID 123°F or • TRANS FLUID 51°C Press the GAGE button again to display the battery voltage, such as: • BATTERY VOLTS 13.5 Press the GAGE button again to display the tire pressure for the front tires (except Z06), such as: • FRONT L34 R33 PSI or • FRONT L234 R228 kPa Press the GAGE button again to display the tire pressure for the rear tires (except Z06), such as: • REAR L34 R33 PSI or • REAR L234 R228 kPa Tire pressure is not available until the vehicle has reached a speed of 15 mph (24 km/h) or more. 3-51 3 TRIP The TRIP button allows you to scroll through the functions listed below when you press it.

Repeat this procedure for loading up to 12 CDs in the magazine. 3-81 Once you have loaded the CDs in the magazine, slide open the door of the CD changer. Push the magazine into the changer in the direction of the arrow marked on top of the magazine. Close the door by sliding it all the way to the left. If the door is left partially open, the changer will not operate and an error will occur. When the door is closed, the changer will begin checking for CDs in the magazine. This will continue for up to two minutes depending on the number of CDs loaded. 3-82 To eject the magazine from the player, slide the CD changer door all the way open. The magazine will automatically eject. Remember to keep the door closed whenever possible to keep dirt and dust from getting inside the changer. Whenever a CD magazine with CDs is loaded in the changer, the CD symbol will appear on the radio display. If the CD changer is checking the magazine for CDs, the CD symbol will ﬂash on the display until the changer is ready to play. When a CD begins playing, CD will appear in the bottom left corner and a CD and track number will appear on the radio display. The CD numbers are listed on the front of the magazine.

It works by using a secret code to disable all radio functions whenever battery power is interrupted. The THEFTLOCK feature for the radio may be used or ignored. If ignored, the system plays normally and the radio is not protected by the feature. If THEFTLOCK is activated, your radio will not operate if stolen. When THEFTLOCK is activated, LOC will appear on the radio display to indicate a locked condition anytime battery power has been interrupted. If your battery loses power for any reason, you must unlock the radio with the secret code before it will operate. Activating the Theft-Deterrent Feature The instructions which follow explain how to enter your secret code to activate the THEFTLOCK system. Read through all nine steps before starting the procedure. If you allow more than 15 seconds to elapse between any steps, the radio automatically reverts to time and you must start the procedure over at Step 4. 1. Write down any three or four-digit number from 000 to 1999 and keep it in a safe place separate from the vehicle. 2. Turn the ignition on. 3. Turn the radio off. 4. Press the 1 and 4 pushbuttons at the same time. Hold them down until --- shows on the display. Next you will use the secret code number which you have written down. 5. Press MN and 000 will appear on the display. 6. Press MN again to make the last two digits agree with your code. 7. Press HR to make the ﬁrst one or two digits agree with your code. 8. Press AM FM after you have conﬁrmed that the code matches the secret code you have written down. The display will show REP to let you know that you need to repeat Steps 5 through 7 to conﬁrm your secret code. 9. Press AM FM and this time the display will show SEC to let you know that your radio is secure. 3-86 Unlocking the Theft-Deterrent Feature After a Power Loss Enter your secret code as follows; pause no more than 15 seconds between steps: 1. Turn the ignition on. LOC will appear on the display. 2. Press MN and 000 will appear on the display. 3. Press MN again to make the last two digits agree with your code. 4. Press HR to make the ﬁrst one or two digits agree with your code. 5. Press AM FM after you have conﬁrmed that the code matches the secret code you have written down. The display will show SEC, indicating the radio is now operable and secure. If you enter the wrong code eight times, INOP will appear on the display. You will have to wait an hour with the ignition on before you can try again. When you try again, you will only have three chances to enter the correct code before INOP appears. If you lose or forget your code, contact your dealer. Disabling the Theft-Deterrent Feature Enter your secret code as follows; pause no more than 15 seconds between steps: 1. Turn the ignition on. 2. Turn the radio off. 3. Press the 1 and 4 pushbuttons at the same time. Hold them down until SEC appears on the display. 4. Press MN and 000 will appear on the display. 5. Press MN again to make the last two digits agree with your code. 6. Press HR to make the ﬁrst one or two digits agree with your code. 7. Press AM FM after you have conﬁrmed that the code matches the secret code you have written down. --- will appear on the display, indicating that the radio is no longer secured. If the code entered is incorrect, SEC will appear on the display. The radio will remain secured until the correct code is entered. When battery power is removed and later applied to a secured radio, the radio won’t turn on and LOC will appear on the display. To unlock a secured radio, see “Unlocking the Theft-Deterrent Feature After a Power Loss” earlier in this section. 3-87 Radio Reception AM The range for most AM stations is greater than for FM, especially at night. The longer range, however, can cause stations to interfere with each other. AM can pick up noise from things like storms and power lines. Try reducing the treble to reduce this noise. FM FM stereo will give you 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 come and go. Care of Your Cassette Tape Player A tape player that is not cleaned regularly can cause reduced sound quality, ruined cassettes, or a damaged mechanism. Cassette tapes should be stored in their cases away from contaminants, direct sunlight, and extreme heat. If they are not, they may not operate properly or may cause failure of the tape player. Your tape player should be cleaned regularly after every 50 hours of use. Your radio may display CLN to indicate that you have used your tape player for 50 hours without resetting the tape clean timer. 3-88 If this message appears on the display, your cassette tape player needs to be cleaned. It will still play tapes, but you should clean it as soon as possible to prevent damage to your tapes and player. If you notice a reduction in sound quality, try a known good cassette to see if the tape or the tape player is at fault. If this other cassette has no improvement in sound quality, clean the tape player. For best results, use a scrubbing action, non-abrasive cleaning cassette with pads which scrub the tape head as the hubs of the cleaner cassette turn. The recommended cleaning cassette is available through your dealer. The cut tape detection feature of your cassette tape player may identify the cleaning cassette as a damaged tape, in error. To prevent the cleaning cassette from being ejected, use the following steps: 1. Turn the ignition on. 2. Turn the radio off. 3. Press and hold the TAPE AUX button for ﬁve seconds. The tape symbol on the display will ﬂash for two seconds. 4. Insert the scrubbing action cleaning cassette. 5. Eject the cleaning cassette after the manufacturer’s recommended cleaning time. After the cleaning cassette is ejected, the cut tape detection feature will be active again. You may also choose a non-scrubbing action, wet-type cleaner which uses a cassette with a fabric belt to clean the tape head. This type of cleaning cassette will not eject on its own. A non-scrubbing action cleaner may not clean as thoroughly as the scrubbing type cleaner. The use of a non-scrubbing action, dry-type cleaning cassette is not recommended. After you clean the player, press and hold the EJECT button for ﬁve seconds to reset the CLN indicator. The radio will display --- or CLEANED to show the indicator was reset. Cassettes are subject to wear and the sound quality may degrade over time. Always make sure the cassette tape is in good condition before you have your tape player serviced. Care of Your CDs Handle CDs carefully. Store them in their original cases or other protective cases and away from direct sunlight and dust. If the surface of a CD is soiled, dampen a clean, soft cloth in a mild, neutral detergent solution and clean it, wiping from the center to the edge. Be sure never to touch the side without writing when handling CDs. Pick up CDs by grasping the outer edges or the edge of the hole and the outer edge. Care of Your CD Player The use of CD lens cleaners for CDs is not advised, due to the risk of contaminating the lens of the CD optics with lubricants internal to the CD mechanism. Fixed Mast Antenna (Z06) The ﬁxed mast antenna can withstand most car washes without being damaged. If the mast should ever become slightly bent, you can straighten it out by hand. If the mast is badly bent, you should replace it. Check occasionally to be sure the mast is still tightened to the rear quarter panel. 3-89 Power Antenna Mast Care (Convertible) Your power antenna will look its best and work well if it is cleaned from time to time. To clean the antenna mast do the following: 1. Turn on the ignition and radio to raise the antenna. 2. Dampen a clean cloth with mineral spirits or equivalent solvent. 3. Wipe the cloth over the mast sections, removing any dirt. 4. Wipe dry with a clean cloth. 5. Make the antenna go up and down by turning the radio or ignition off and on. If you lubricate the power antenna, you may 6. Repeat if necessary. Notice: damage it. Always follow the cleaning instructions listed in this manual to keep the power antenna working properly. Notice: Before entering an automatic car wash, turn off your radio to make the power antenna go down. This will prevent the mast from possible damage. If the antenna does not go down when you turn the radio off, it may be damaged or need to be cleaned. In either case, lower the antenna by hand by carefully pressing the antenna down. If the mast portion of your antenna is damaged, you can replace it. See your dealer for a replacement kit and follow the instructions in the kit. Integrated Windshield and Rear Window Antennas (Coupe) The antennas in your vehicle are located in the windshield and the rear window. The front connector is at the top of the windshield and the rear antenna is incorporated in the rear window defogger grid. Notice: Do not apply aftermarket glass tinting with metallic ﬁlm. The metallic ﬁlm in some tinting materials will interfere with or distort the incoming radio reception. Any damage caused to your backglass antenna due to metallic tinting materials will not be covered by your warranty. 3-90 Section 4 Driving Your Vehicle Your Driving, the Road, and Your Vehicle ..........4-2 Defensive Driving ...........................................4-2 Drunken Driving .............................................4-3 Control of a Vehicle ........................................4-6 Braking .........................................................4-6 Traction Control System (TCS) .........................4-9 Active Handling System .................................4-10 Limited-Slip Rear Axle ...................................4-12 Selective Ride Control ...................................4-12 Steering ......................................................4-14 Off-Road Recovery .......................................4-16 Passing .......................................................4-16 Loss of Control .............................................4-18 Driving at Night ............................................4-19 Driving in Rain and on Wet Roads ..................4-20 City Driving ..................................................4-23 Freeway Driving ...........................................4-24 Before Leaving on a Long Trip .......................4-25 Highway Hypnosis ........................................4-26 Hill and Mountain Roads ................................4-26 Winter Driving ..............................................4-28 If You Are Stuck: In Sand, Mud, Ice or Snow ..............................................4-32 Towing ..........................................................4-33 Towing Your Vehicle .....................................4-33 Recreational Vehicle Towing ...........................4-33 Loading Your Vehicle ....................................4-33 Towing a Trailer ...........................................4-38 4-1 Your Driving, the Road, and Your Vehicle 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 1-6. Defensive driving really means “be ready for anything.” On city streets, rural roads or freeways, 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. Be ready for their mistakes. Rear-end collisions are about the most preventable of accidents. Yet they are common. Allow enough following distance. It is the best defensive driving maneuver, in both city and rural driving. You never know when the vehicle in front of you is going to brake or turn suddenly. Defensive driving requires that a driver concentrate on the driving task. Anything that distracts from the driving task — such as concentrating on a cellular telephone call, reading, or reaching for something on the ﬂoor — makes proper defensive driving more difficult and can even cause a collision, with resulting injury. Ask a passenger to help do things like this, or pull off the road in a safe place to do them yourself. These simple defensive driving techniques could save your life. 4-2 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: • Judgment • Muscular Coordination • Vision • 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.
