Notes On Playing MP3 Files The radio can play MP3 files, however, acceptable MP3 file recording media and formats are limited. When writing MP3 files, pay attention to the following restric- tions. Supported Media (Disc Types) The MP3 file recording media supported by the radio are CD-ROM, CD-R and CD-RW. Supported Medium Formats (File Systems) The medium formats supported by the radio are ISO 9660 Level 1 and Level 2 and includes the Joliet extension. When reading discs recorded using formats other than ISO 9660 Level 1 and Level 2, the radio may fail to read files properly and may be unable to play the file nor- mally. UDF and Apple HFS formats are not supported. The radio uses the following limits for file systems: • Maximum number of directory levels: 15 • Maximum number of files: 255 • Maximum number of folders: 100 • Maximum number of characters in file/folder names: • Level 1: 12 (including a separator ⬙.⬙ and a • Level 2: 31 (including a separator 3-character extension) ⬙.⬙ and a 3-character extension) Multisession disc formats are supported by the radio. Multisession discs may contain combinations of normal CD audio tracks and computer files (including MP3 files). Discs created with an option such as ⬙keep disc open after writing⬙ are most likely multisession discs. The use of multisession for CD audio or MP3 playback may result in longer disc loading times. UNDERSTANDING YOUR INSTRUMENT PANEL 205 Supported MP3 File Formats The radio will recognize only files with the *.mp3 exten- sion as MP3 files. Non-MP3 files named with the *.mp3 extension may cause playback problems. The radio is designed to recognize the file as an invalid MP3 and will not play the file. When using the MP3 encoder to compress audio data to an MP3 file, the bit rate and sampling frequencies in the following table are supported. In addition, variable bit rates (VBR) are also supported. The majority of MP3 files use a 44.1 kHz sampling rate and a 192, 160, 128, 96 or VBR bit rates. 206 UNDERSTANDING YOUR INSTRUMENT PANEL MPEG Specifi- cation Sampling Fre- quency (kHz) MPEG-1 Audio Layer 3 48, 44.1, 32 MPEG-2 Audio Layer 3 24, 22.05, 16 Bit rate (kbps) 320, 256, 224, 192, 160, 128, 112, 96, 80, 64, 56, 48, 40, 32 160, 128, 144, 112, 96, 80, 64, 56, 48, 40, 32, 24, 16, 8 ID3 Tag information for artist, song title and album title are supported for version 1 ID3 tags.

UNDERSTANDING YOUR INSTRUMENT PANEL 221 RADIO OPERATION AND CELLULAR PHONES Under certain conditions, the cellular phone being On in your vehicle can cause erratic or noisy performance from your radio. This condition may be lessened or eliminated by relocating the cellular phone antenna. This condition is not harmful to the radio. If your radio performance does not satisfactorily “clear” by the repositioning of the antenna, it is recommended that the radio volume be turned down or off during cellular phone operation. CD/DVD DISC MAINTENANCE To keep the CD/DVD discs in good condition, take the following precautions: 1. Handle the disc by its edge; avoid touching the surface. 2. If the disc is stained, clean the surface with a soft cloth, wiping from center to edge. 3. Do not apply paper, paper CD labels, or tape to the disc; avoid scratching the disc. 4. Do not use solvents such as benzine, thinner, cleaners, or antistatic sprays. 5. Store the disc in its case after playing. 6. Do not expose the disc to direct sunlight. 7. Do not store the disc where temperatures may become too high. 222 UNDERSTANDING YOUR INSTRUMENT PANEL CLIMATE CONTROLS Automatic Temperature Control The Infrared Dual-Zone Climate Control System auto- matically maintains the interior comfort level desired by the driver and passenger. This is accomplished by a dual sun-sensor in the top of the instrument panel, and an infrared sensor located in the face of the control unit. There are also various sensors monitored by this system which take account for vehicle speed, A/C pressure, outside temperature, and engine cooling temperature. The infrared sensor independently measures the surface temperature of the driver and passenger. Based on the sensor input, the system automatically adjusts the air flow temperature, the air flow volume, and amount of outside air recirculation. This maintains a comfortable temperature even under changing conditions. Automatic Temperature Controls NOTE: The numbers on the temperature dial represent a comfort setting when the Mode knob is set to Auto, and not the actual air temperature. Operation of the system is quite simple. Begin by turning the right mode knob to AUTO, and place the blower control (left knob) to either LO AUTO or HI AUTO. The LO AUTO position should be used for front seat occu- pants only. The HI AUTO position should be used when more air flow is desired, or when rear seat occupants are present. Dial in the comfort setting you would like the system to maintain by rotating the driver’s or passenger’s control knob. Once the comfort level is selected the system will maintain that level automatically using the heating system. Should the desired comfort level require air conditioning, the system will automatically make the adjustment. You will experience the greatest efficiency by simply allowing the system to function automatically. Selecting the OFF position on the fan control stops the system completely. NOTE: The temperature setting can be adjusted at any time without affecting automatic control operation. How- ever, if the driver and/or passenger temperature knobs are set to the full hot or full cold positions, the air UNDERSTANDING YOUR INSTRUMENT PANEL 223 temperature out of the ducts will be full hot or full cold respectively. With the temperature setting in these posi- tions, the system does not attempt automatic comfort control. The air conditioning in this system is automatic. Pressing this button while in AUTO mode will cause the LED to flash three times and remain off. This indicates that the system is in AUTO and requesting the air conditioning is not necessary. The system will automatically control recircu- lation. However, pressing this button will tem- porarily put the system in recirculation mode. This can be used when outside conditions such as smoke, odors, dust, or high humidity are present. This will cause the LED to illuminate. NOTE: • The surface of the climate control panel, and the top center of the instrument panel should be kept free of 224 UNDERSTANDING YOUR INSTRUMENT PANEL debris due to the climate control sensor’s location. Mud on the windshield may also cause poor operation of this system. • To provide you with maximum comfort in the auto- matic mode, during cold start-ups the blower fan will remain off until the engine warms up. However, the fan will engage immediately if the defrost mode is selected or if you manually select a blower speed. • Under certain conditions (after the vehicle is turned off) the climate control system may recalibrate and a noise may be heard for 20 seconds. This is part of normal operation. • Most of the time, when in Automatic operation, you can temporarily put the system into recirculation mode by pressing the Recirc button. However, under certain conditions in automatic the system is blowing air out of the defrost vents. When these conditions are present and the Recirc button is pressed the indicator will flash and remain off. This tells you that you are unable to go into recirculation mode at this time. If you would like to go to Recirculation mode, you must first move your mode knob to panel, panel/floor or floor, then hit the Recirc button. This feature will reduce the possibility of window fogging. Manual Operation This system offers a full complement of manual override features which consist of Blower Preferred Automatic, Mode Preferred Automatic with Manual Air Temperature Control and Manual. This means the customer can over- ride the blower, mode and disable automatic temperature control completely. NOTE: Please read the Automatic Temperature Control Operation Chart below for details. UNDERSTANDING YOUR INSTRUMENT PANEL 225 226 UNDERSTANDING YOUR INSTRUMENT PANEL NOTE: Regardless of the type of operation, when a temperature knob is set to the full clockwise or full counterclockwise position, the system will deliver full hot or full cold air out of the ducts, respectively. The operator can override the AUTO mode setting and select the direction of the air by rotating the right mode knob to one of the following positions. When the Mode is set to any position other than AUTO, the automatic control of air temperature is disabled. The user must adjust the temperature knobs to obtain the desired tem- perature. • Defrost Air is directed to the windshield through the outlets at the base of the windshield. Air is also directed to the front door windows through the side window demister grilles. Some airflow is delivered to the floor while in defrost so that comfort can be maintained. NOTE: The defrost mode is not automatically selected. It must be manually selected, when desired. • Defrost/Floor Air flows through the front and rear floor outlets and the outlets at the base of the windshield. Air is also directed to the front door windows through the side window demister grilles. Some air- flow is delivered to the floor while in defrost so that comfort can be maintained. • Floor Air flows through the floor outlets located under the instrument panel and into the rear seating area through vents under the front seats. Some airflow is delivered to defrost while in floor mode, so that comfort can be maintained. • Bi-Level Air flows both through the outlets located in the instrument panel and those located on the floor. Air flows through the registers in the back of the center console, and under the front seats to the rear seat passengers. These registers can be closed to block airflow. The center console outlets deliver conditioned air while the floor outlets deliver heated air. • Panel Air flows through the outlets located in the in- strument panel. Air flows through the registers in the back of the center console to the rear seat passen- gers. These registers can be closed to block airflow. Depress this button to turn on and off the air conditioning during manual operation only. Con- ditioned outside air is then directed through the outlets selected on the mode control dial. The button includes an LED that illuminates when manual operation is selected. NOTE: To manually control the air conditioning the mode selector must be moved out of the AUTO position. UNDERSTANDING YOUR INSTRUMENT PANEL 227 This button can be used to block out smoke, odors, dust, high humidity, or if rapid cooling is desired. The recirculation mode should only be used temporarily. The button includes an LED that illuminates, which indicates that the recircula- tion mode is active. You may use this feature separately. NOTE: Extended use of recirculation may cause the windows to fog. If the interior of the windows begins to fog, press the “Recirculate” icon button to return to outside air. Some temp./humidity conditions will cause captured interior air to condense on windows and ham- per visibility. For this reason, the system will not allow “Recirculate” to be selected while in the defrost or defrost/floor modes. Attempting to use the recirculation while in these modes will cause the LED in the button to blink and then turn off. 228 UNDERSTANDING YOUR INSTRUMENT PANEL Operating Tips Window Fogging Windows will fog on the inside when the humidity inside the vehicle is high. This often occurs in mild or cool temperatures when it’s rainy or humid. In most cases turning on the Air-conditioning (pressing the snowflake button) will clear the fog. Adjust the temperature control, air direction and blower speed to maintain comfort. As the temperature gets colder it may be necessary to direct air onto the windshield. Adjust the temperature control and blower speed to maintain comfort. Higher blower speeds will reduce fogging. Interior fogging on the windshield can be quickly removed by selecting the defrost mode. Regular cleaning of the inside of the windows with a non-filming cleaning solution (vinegar and water works very well) will help prevent contaminates (cigarette smoke, perfumes, etc.) from sticking to the windows. Contaminates increase the rate of window fogging. Summer Operation Air conditioned vehicles must be protected with a high quality antifreeze coolant during summer to provide proper corrosion protection and to raise the boiling point of the coolant for protection against overheating. A 50 % concentration is recommended. Refer to Recommended Fluids and Genuine Parts for the proper coolant type. When using the air conditioner in extremely heavy traffic in hot weather especially when towing a trailer, addi- tional engine cooling may be required. If this situation is encountered, operate the transmission in a lower gear to increase engine RPM, coolant flow and fan speed. When stopped in heavy traffic, it may be necessary to shift into N (Neutral) and depress the accelerator slightly for fast idle operation to increase coolant flow and fan speed. Your air conditioning system is also equipped with an automatic recirculation system. When the system senses a heavy load or high heat conditions, it may use partial Recirculation A/C mode to provide additional comfort. Winter Operation When operating the system during the winter months, make sure the air intake, located directly in front of the windshield, is free of ice, slush, snow, or other obstruc- tions. UNDERSTANDING YOUR INSTRUMENT PANEL 229 Vacation Storage Anytime you store your vehicle, or keep it out of service (i.e. vacation) for two weeks or more, run the air condi- tioning system at idle for about five minutes in the fresh air and high blower setting. This will insure adequate system lubrication to minimize the possibility of com- pressor damage when the system is started again.

CAUTION! Long periods of engine idling, especially at high engine speeds can cause excessive exhaust tempera- tures which can damage your vehicle. Do not leave your vehicle unattended with the engine running. WARNING! Do not leave children or animals inside parked vehicles in hot weather. Interior heat build up may cause serious injury or death. Start the engine with the gear selector in the N (Neutral) or P (Park) position. Apply the brakes before shifting to any driving gear. Normal Starting Do not press the accelerator. Turn the ignition key briefly to START position, and release it. The starter motor will continue to run, but will automatically disengage itself when the engine is running. NOTE: The starter motor may run up to 30 seconds in very cold conditions until the engine is started. The starter can be disengaged by turning the ignition key to the OFF position, if required. STARTING AND OPERATING 235 If Engine Fails to Start If the engine fails to start after you have followed the “Normal Starting” or “Extreme Cold Weather” proce- dures, it may be flooded. Push the accelerator pedal all the way to the floor and hold it there while cranking the engine. This should clear any excess fuel in case the engine is flooded. CAUTION! To prevent damage to the starter, do not crank the engine for more than 15 seconds at a time. Wait 10 to 15 seconds before trying again. Ignition Key Positions Extreme Cold Weather (below –20°F (–29°C) To insure reliable starting at these temperatures, use of an externally powered electric engine block heater (available from your authorized dealer) is recommended. 236 STARTING AND OPERATING WARNING! WARNING! Never pour fuel or other flammable liquids into the throttle body air inlet opening in an attempt to start the vehicle. This could result in a flash fire causing serious personal injury. Do not attempt to push or tow your vehicle to get it started. Vehicles equipped with an automatic trans- mission cannot be started this way. Unburned fuel could enter the catalytic converter and once the engine has started, ignite and damage the converter and vehicle. If the vehicle has a discharged battery, booster cables may be used to obtain a start from a booster battery or the battery in another vehicle. This type of start can be dangerous if done improperly. Refer to Section 6 of this manual for proper jump starting procedures and follow them carefully. If the engine has been flooded, it may start to run, but not have enough power to continue running when the key is released. If this occurs, continue cranking with the accel- erator pedal pushed all the way to the floor. Release the accelerator pedal and the key once the engine is running smoothly. If the engine shows no sign of starting after two 15– second periods of cranking with the accelerator pedal held to the floor, the “Normal Starting” or “Extreme Cold Weather” procedures should be repeated. After Starting The idle speed will automatically decrease as the engine warms up. STARTING AND OPERATING 237 CAUTION! Long periods of engine idling, especially at high engine speeds can cause excessive exhaust tempera- tures which can damage your vehicle. Do not leave your vehicle unattended with the engine running. WARNING! Do not leave children or animals inside parked vehicles in hot weather. Interior heat build up may cause serious injury or death. 238 STARTING AND OPERATING AUTOMATIC TRANSMISSION CAUTION! to a complete stop. Damage to the transmission may occur if the follow- ing precautions are not observed: • Shift into P (Park) only after the vehicle has come • Shift into or out of R (Reverse) only after the vehicle has come to a complete stop and the engine is at idle speed. • Do not shift from R (Reverse), P (Park), or N (Neutral) into any forward gear when the engine is above idle speed. • Before shifting into any gear, make sure your foot is firmly on the brake pedal. WARNING! It is dangerous to shift the selector lever out of P (Park) or N (Neutral) if the engine speed is higher than idle speed. If your foot is not firmly on the brake pedal, the vehicle could accelerate quickly forward or in reverse. You could lose control of the vehicle and hit someone or something. Only shift into gear when the engine is idling normally and when your foot is firmly on the brake pedal. Brake/Transmission Interlock System This system prevents you from moving the gear shift out of P (Park) and into any gear unless the brake pedal is pressed. This system is active only while the ignition switch is in the ON position. Always depress the brake pedal first, before moving the gear selector out of P (Park). 5–Speed Automatic Transmission The electronically controlled transmission provides a precise shift schedule. The transmission electronics are self-calibrating; therefore, the first few shifts on a new vehicle, may be somewhat abrupt. This is a normal condition, and precision shifts will develop within a few hundred miles. Automatic Shift Controls STARTING AND OPERATING 239 WARNING! It is dangerous to shift the selector lever out of P (Park) or N (Neutral) if the engine speed is higher than idle speed. If your foot is not firmly on the brake pedal, the vehicle could accelerate quickly forward or in reverse. You could lose control of the vehicle and hit someone or something. Only shift into gear when the engine is idling normally and when your foot is firmly on the brake pedal. Gear Ranges NOTE: After selecting any gear range, wait a moment to allow the selected gear to engage before accelerating. This is especially important when the engine is cold. If there is a need to restart the engine be sure to cycle the key to the LOCK position before restarting. Transmission gear engagement may be delayed after restarting the engine if the key is not cycled to the LOCK position first. 240 STARTING AND OPERATING P (Park) Supplements the parking brake by locking the transmis- sion. The engine can be started in this range. Never use P (Park) while the vehicle is in motion. Apply the parking brake when leaving the vehicle in this range. WARNING! Unintended movement of a vehicle could injure those in and near the vehicle. As with all vehicles, you should never exit a vehicle while the engine is running. Before exiting a vehicle, you should apply the park brake, shift the transmission into P (Park), and remove the key from the ignition. Once the key is removed from the ignition the transmission shift lever is locked in the P (Park) position, securing the vehicle against unwanted movement. Furthermore, you should never leave children unattended inside a vehicle. R (Reverse) Shift into this range only after the vehicle has come to a complete stop. N (Neutral) No power is transmitted from the engine to the drive axle. When the brakes are released, the vehicle can roll freely. Do not engage in N (Neutral) position while driving except to coast when the vehicle is in danger of skidding (e.g., on icy roads). D (Drive) The transmission automatically upshifts through fifth gear. The D (Drive) position provides optimum driving characteristics under all normal operating conditions. For additional shifting information, refer to “Autostick” later in this section. Rocking the Vehicle If the vehicle becomes stuck in snow, sand, or mud, it can often be moved by a rocking motion. Move the gear selector rhythmically between D (Drive) and R (Reverse), while applying slight pressure to the accelerator. NOTE: The Electronic Stability Program (ESP) and Traction Control (if equipped) should be turned OFF before attempting to rock the vehicle. Refer to “Electronic Brake Control System” in Section 3 of this manual. The least amount of accelerator pedal pressure to main- tain the rocking motion without spinning the wheels or racing the engine is most effective. Racing the engine or spinning the wheels, due to the frustration of not freeing the vehicle, may lead to transmission overheating and failure. Allow the engine to idle with the transmission selector in N (Neutral) for at least one minute after every STARTING AND OPERATING 241 five rocking-motion cycles. This will minimize overheat- ing and reduce the risk of transmission failure during prolonged efforts to free a stuck vehicle. CAUTION! When “rocking” a stuck vehicle by moving between “First” and R (Reverse), do not spin the wheels faster than 15 mph (24 km/h), or drivetrain damage may result. AUTOSTICK Autostick is a driver-interactive transmission that offers manual gear shifting capability to provide the driver with more control. Autostick allows the driver to increase engine braking ability, control upshift and downshift points, and enhance the driving experience. This system 242 STARTING AND OPERATING can also provide the driver with more control during passing, city driving, mountain driving, trailer towing, and many other situations. Autostick Operation By placing the shift lever in the D (Drive) position the lever can be moved from side to side. This allows the driver to engage the AutoStick mode. Moving the shift lever to the right (+) or the left (-) will engage the Autostick mode. In normal driving mode (Boxed “D” displayed in the PRNDL), moving the shift lever to the right (+) will engage the Autostick mode putting the transmission in the currently engaged gear. Moving the shift lever to the Left (-) will engage the Autostick mode and downshift the transmission 1 gear. For example, the transmission is in Normal Mode and is currently operat- ing in 3rd gear, a boxed D is displayed in the PRNDL, a push to the right will engage the Autostick mode in 3rd and a Boxed 3 will be displayed in the PRNDL. A push to the left (-) will engage Autostick mode and downshift to 2nd gear and a Boxed 2 will be displayed in the PRNDL. Once Autostick mode is engaged a move to the Right (+) or left (-) will trigger a upshift (+) or trigger a downshift (-). In the Autostick mode, the transmission will NOTE: only shift up and down when Left or Right (D-/D+) is manually selected by the driver. The transmission will not allow a downshift if the downshift would result in a engine overspeed condition. The transmission will always allow a upshift from 1st to 2nd gear, however 2nd - 3rd, 3rd - 4th, and 4th – 5th upshifts will not be allowed if the vehicle speed is to low to maintain operation in the selected gear. The transmis- sion will automatically downshift as the vehicle slows to a stop. When in the Autostick mode, as the engine RPM nears the engine maximum speed, an “UPSHIFT” message will appear in the Electronic Vehicle Information Center (EVIC) portion of your instrument cluster. This message appears in order to alert the driver that the engine speed is approaching it’s maximum value and a upshift to the next gear is required. In the event that the driver does not upshift, the engine control system will limit the engine speed to protect the engine. Refer to “Electronic Vehicle Information Center” in Section 4 of this manual. Shifting into or out of the Autostick mode can be done at any time without taking your foot off the accelerator pedal. When the driver wishes to engage Autostick, simply move the shift lever to the Left or Right (D-/D+) position while in D (Drive). Hold the shift lever to the right for at least one second to disengage Autostick. The transmission will now operate automatically; shifting between the five available gears. STARTING AND OPERATING 243 gear when coming to a stop. Autostick General Information • You can start out in first or second gear. The system will ignore attempts to upshift at too low of a vehicle speed. • The transmission will automatically downshift to first • Starting out in second gear is helpful in snowy or icy • Avoid using speed control when Autostick is engaged. • The transmission will not automatically shift up when maximum engine speed is reached while Autostick is engaged. • Transmission shifting will be more noticeable when conditions. Autostick is engaged. 244 STARTING AND OPERATING PARKING BRAKE To set the parking brake, pull the lever up as firmly as possible. When the parking brake is applied with the ignition ON, the “Brake Warning Light” in the instru- ment cluster will light. To release the parking brake, pull up slightly, press the center button, then lower the lever completely. NOTE: The instrument cluster “Brake Warning Light” indicates only that the parking brake is applied. It does not indicate the degree of brake application. Parking Brake Be sure the parking brake is firmly set when parked and the gear shift lever is in the P (Park) position. When parking on a hill, you should apply the parking brake before placing the gear shift lever in P (Park), otherwise the load on the transmission locking mechanism may make it difficult to move the selector out of P (Park). WARNING! • Always fully apply the parking brake when leav- ing your vehicle, or it may roll and cause damage or injury. Also, be certain to leave the transmis- sion in P (Park). Failure to do so may allow the vehicle to roll and cause damage or injury. • Leaving children in a vehicle unattended is dan- gerous for a number of reasons. A child or others could be injured. Children should be warned not to touch the parking brake or the gear selector lever. Don’t leave the keys in the ignition. A child could operate power windows, other controls, or move the vehicle. • Be sure the parking brake is fully disengaged before driving, failure to do so can lead to brake problems due to excessive heating of the rear brakes. STARTING AND OPERATING 245 When parking on a hill, turn the front wheels toward the curb on a downhill grade and away from the curb on an uphill grade. The parking brake should always be applied whenever the driver is not in the vehicle. ANTI-LOCK BRAKE SYSTEM The Anti-Lock Brake System (ABS) is designed to aid the driver in maintaining vehicle control under adverse braking conditions. The system operates with a separate computer to modulate hydraulic pressure to prevent wheel lock-up and help avoid skidding on slippery surfaces. All vehicle wheels and tires must be the same size and type and tires must be properly inflated to produce accurate signals for the computer. 246 STARTING AND OPERATING WARNING! WARNING! Pumping of the Anti-Lock Brakes will diminish their effectiveness and may lead to an accident. Pumping makes the stopping distance longer. Just press firmly on your brake pedal when you need to slow down or stop. Significant over or under inflation of tires can lead to loss of braking effectiveness. The Anti-Lock Brake System conducts a low-speed self- test at about 12 mph (20 km/h). If you have your foot lightly on the brake while this test is occurring you may feel slight pedal movement. The movement can be more apparent on ice and snow. This is normal. The Anti-Lock Brake System pump motor runs during the self-test at 12 mph (20 km/h) and during an ABS stop. The pump motor makes a low humming noise during operation, which is normal. WARNING! • The Anti-Lock Brake System (ABS) cannot pre- vent the natural laws of physics from acting on the vehicle, nor can it increase braking or steering efficiency beyond that afforded by the condition of the vehicle brakes and tires or the traction afforded. • The ABS cannot prevent accidents, including those resulting from excessive speed in turns, following another vehicle too closely, or hydro- planing. Only a safe, attentive, and skillful driver can prevent accidents. • The capabilities of an ABS equipped vehicle must never be exploited in a reckless or dangerous manner which could jeopardize the user’s safety or the safety of others. STARTING AND OPERATING 247 CAUTION! The Anti-Lock Brake System is subject to possible detrimental effects of electronic interference caused by improperly installed after-market radios or tele- phones. NOTE: During severe braking conditions, a pulsing sensation may occur and a clicking noise will be heard. This is normal, the Anti-Lock Brake System is functioning. indicating that WARNING! To use your brakes and accelerator more safely, follow these tips: 248 STARTING AND OPERATING • Do not “ride” the brakes by resting your foot on the pedal. This could overheat the brakes and result in longer stopping dis- unpredictable braking action, tances, or brake damage. • When descending mountains or hills, repeated brak- ing can cause brake fade with loss of braking control. Avoid repeated heavy braking by downshifting the transmission or locking out overdrive whenever pos- sible. • Engines may idle at higher speeds during warm-up, which could cause rear wheels to spin and result in loss of vehicle control. Be especially careful while driving on slippery roads, in close-quarter maneuver- ing, parking or stopping. • Do not drive too fast for road conditions, especially when roads are wet or slushy. A wedge of water can build up between the tire tread and the road. This hydroplaning action can cause loss of traction, braking ability, and control. • After going through deep water or a car wash, brakes may become wet, resulting in decreased performance and unpredictable braking action. Dry the brakes by gentle, intermittent pedal action while driving at very slow speeds. POWER STEERING The standard power steering system will give you good vehicle response and increased ease of maneuverability in tight spaces. The system will provide mechanical steering capability if power assist is lost. If for some reason the power assist is interrupted, it will still be possible to steer your vehicle. Under these condi- tions, you will observe a substantial increase in steering effort, especially at very low vehicle speeds and during parking maneuvers. Increased noise levels at the end of the steering NOTE: wheel travel are considered normal and do not indicate that there is a problem with the power steering system. Upon initial start-up in cold weather, the power steering pump may make noise for a short amount of time. This is due to the cold, thick fluid in the steering system. This noise should be considered normal, and does not in any way damage the steering system. WARNING! Continued operation with reduced power steering assist could pose a safety risk to yourself and others. Service should be obtained as soon as possible. STARTING AND OPERATING 249 CAUTION! Prolonged operation of the steering system at the end of the steering wheel travel will increase the steering fluid temperature and it should be avoided when possible. Damage to the power steering pump may occur. 250 STARTING AND OPERATING TIRE SAFETY INFORMATION Tire Markings NOTE: • P (Passenger)-Metric tire sizing is based on U.S. design standards. P-Metric tires have the letter “P” molded into the sidewall preceding the size designation. Ex- ample: P215/65R15 95H. • European Metric tire sizing is based on European design standards. Tires designed to this standard have the tire size molded into the sidewall beginning with the section width. The letter ⬙P⬙ is absent from this tire size designation. Example: 215/65R15 96H • LT (Light Truck)-Metric tire sizing is based on U.S. design standards. The size designation for LT-Metric tires is the same as for P-Metric tires except for the letters “LT” that are molded into the sidewall preced- ing the size designation. Example: LT235/85R16. • Temporary Spare tires are high-pressure compact spares designed for temporary emergency use only. Tires designed to this standard have the letter “T” molded into the sidewall preceding the size designa- tion. Example: T145/80D18 103M. • High Flotation tire sizing is based on U.S. design standards and it begins with the tire diameter molded into the sidewall. Example: 31x10.5 R15 LT.

Tire and Loading Information Placard Tire and Loading Information This placard tells you important information about the: 1) number of people that can be carried in the vehicle 2) the total weight your vehicle can carry 3) the tire size designed for your vehicle 4) the cold tire inflation pressures for the front, rear and spare tires. Tire Placard Location Loading The vehicle maximum load on the tire must not exceed the load carrying capacity of the tire on your vehicle. You will not exceed the tire’s load carrying capacity if you adhere to the loading conditions, tire size, and cold tire inflation pressures specified on the “Tire and Loading Information” placard and in the “Vehicle Loading” sec- tion of this manual. NOTE: Under a maximum loaded vehicle condition, gross axle weight ratings (GAWR’s) for the front and rear axles must not be exceeded. For further information on GAWR’s, vehicle loading, and trailer towing, refer to the “Vehicle Loading” section of this manual. To determine the maximum loading conditions of your vehicle, locate the statement “The combined weight of occupants and cargo should never exceed XXX kg or XXX lbs.” on the Tire and Loading Information placard. The STARTING AND OPERATING 255 combined weight of occupants, cargo/luggage and trailer tongue weight (if applicable) should never exceed the weight referenced here. Steps for Determining Correct Load Limit 1. Locate the statement “The combined weight of occu- pants and cargo should never exceed XXX pounds” on your vehicle’s placard. 2. Determine the combined weight of the driver and passengers that will be riding in your vehicle. 3. Subtract the combined weight of the driver and pas- sengers from XXX kilograms or XXX pounds. 4. The resulting figure equals the available amount of cargo and luggage load capacity. For example, if “XXX” amount equals 1400 lbs. and there will be five 150 lb. 256 STARTING AND OPERATING passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lbs. (since 5 x 150 = 750, and 1400 – 750 = 650 lbs.) 5. Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage load capacity calculated in Step 4. 6. If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Consult this manual to determine how this reduces the available cargo and luggage load capacity of your vehicle. NOTE: The following table shows examples on how to calculate total load, cargo/luggage, and towing capaci- ties of your vehicle with varying seating configurations and number and size of occupants. This table is for illustration purposes only and may not be accurate for the seating and load carry capacity of your vehicle. NOTE: For the following example, the combined weight of occupants and cargo should never exceed 865 lbs. (392 Kg). STARTING AND OPERATING 257 258 STARTING AND OPERATING WARNING! WARNING! Overloading of your tires is dangerous. Overloading can cause tire failure, affect vehicle handling, and increase your stopping distance. Use tires of the recommended load capacity for your vehicle. Never overload them. Do not exceed 50 mph (80 km/h) if the “Tire Pressure Monitoring Telltale Light” is illuminated. Vehicle handling and braking may be reduced. You could have an accident and be severely or fatally injured. TIRES — GENERAL INFORMATION Run Flat Tires This vehicle is equipped with run flat tires. Although the tires are designed with a “run flat” feature that allows the vehicle to be driven about 50 miles (80 km) at 55 mph (88 km/h), immediate service should be obtained. NOTE: The “run flat” feature eliminates the need for a spare tire or jack. This vehicle is not equipped with either a spare tire or jack. Tire Pressure Proper tire inflation pressure is essential to the safe and satisfactory operation of your vehicle. Three primary areas are affected by improper tire pressure: 1. Safety— WARNING! Improperly inflated tires are dangerous and can cause accidents. • Under inflation increases tire flexing and can result in tire failure. • Over inflation reduces a tire’s ability to cushion shock. Objects on the road and chuck holes can cause damage that results in tire failure. • Unequal tire pressures can cause steering problems. You could lose control of your vehicle. • Overinflated or under inflated tires can affect vehicle handling and can fail suddenly, resulting in loss of vehicle control. • Unequal tire pressures from one side of the vehicle to the other can cause the vehicle to drift to the right or left. Always drive with each tire properly inflated. STARTING AND OPERATING 259 2. Economy— Improper inflation pressures can cause uneven wear patterns to develop across the tire tread. These abnormal wear patterns will reduce tread life resulting in a need for earlier tire replacement. Under inflation also increases tire rolling resistance and results in higher fuel consump- tion. 3. Ride Comfort and Vehicle Stability— Proper tire inflation contributes to a comfortable ride. Over inflation produces a jarring and uncomfortable ride. Both under inflation and over inflation affect the stability of the vehicle and can produce a feeling of sluggish response or over responsiveness in the steering. Unequal tire pressures can cause erratic and unpredict- able steering response. Unequal tire pressure from side to side may cause the vehicle to drift left or right. 260 STARTING AND OPERATING Tire Inflation Pressures The proper cold tire inflation pressure is listed on either the face of the driver’s door, or the driver’s side “B” pillar. check tire pressure. Do not make a visual judgement when determining proper inflation. Radial tires may look properly inflated even when they are under inflated. CAUTION! After inspecting or adjusting the tire pressure al- ways reinstall the valve stem cap–if equipped. This will prevent moisture and dirt from entering the valve stem, which could damage the valve stem. Inflation pressures specified on the placard are always “cold tire inflation pressure”. Cold tire inflation pressure is defined as the tire pressure after the vehicle has not been driven for at least 3 hours, or driven less than 1 mile (1 km) after a 3 hour period. The cold tire inflation pressure must not exceed the maximum inflation pres- sure molded into the tire side wall. Tire Placard Location The pressure should be checked and adjusted as well as inspecting for signs of tire wear or visible damage at least once a month. Use a good quality pocket-type gauge to STARTING AND OPERATING 261 Tire Pressures for High Speed Operation The manufacturer advocates driving at safe speeds within posted speed limits. Where speed limits or condi- tions are such that the vehicle can be driven at high speeds, maintaining correct tire inflation pressure is very important. Increased tire pressure and reduced vehicle loading may be required for high speed vehicle opera- tion. Refer to original equipment or an authorized tire dealer for recommended safe operating speeds, loading and cold tire inflation pressures. Check tire pressures more often if subject to a wide range of outdoor temperatures, as tire pressures vary with temperature changes. Tire pressures change by approximately 1 psi (7 kPa) per 12° F (7° C) of air temperature change. Keep this in mind when checking tire pressure inside a garage especially in the winter. Example: If garage temperature = 68° F (20° C) and the outside temperature = 32° F (0° C) then the cold tire inflation pressure should be increased by 3 psi (21 kPa), which equals 1 psi (7 kPa) for every 12° F (7° C) for this outside temperature condition. Tire pressure may increase from 2 to 6 psi (13 to 40 kPa) during operation. DO NOT reduce this normal pressure build up or your tire pressure will be too low. 262 STARTING AND OPERATING WARNING! Radial-Ply Tires High speed driving with your vehicle under maxi- mum load is dangerous. The added strain on your tires could cause them to fail. You could have a serious accident. Don’t drive a vehicle loaded to the maximum capacity at continuous speeds above 75 mph (120 km/h). WARNING! Combining radial ply tires with other types of tires on your vehicle will cause your vehicle to handle poorly. The instability could cause an accident. Al- ways use radial tires in sets of four. Never combine them with other types of tires. Cuts and punctures in radial tires are repairable only in the tread area because of sidewall flexing. Consult your dealer for radial tire repairs. Tire Spinning When stuck in mud, sand, snow, or ice conditions, do not spin your vehicle’s wheels above 35 mph (55 km/h). WARNING! Fast spinning tires can be dangerous. Forces gener- ated by excessive wheel speeds may cause tire dam- age or failure. A tire could explode and injure someone. Do not spin your vehicle’s wheels faster than 35 mph (55 km/h) when you are stuck, and do not let anyone near a spinning wheel no matter what the speed. STARTING AND OPERATING 263 Tread Wear Indicators Tread wear indicators are in the original equipment tires to help you in determining when your tires should be replaced. These indicators are molded into the bottom of the tread grooves and will appear as bands when the tread depth 264 STARTING AND OPERATING becomes 1/16 inch (2 mm). When the indicators appear in 2 or more adjacent grooves, the tire should be replaced. Many states have laws requiring tire replacement at this point. Life of Tire The service life of a tire is dependent upon varying factors including but not limited to: • Driving style • Tire pressure • Distance driven WARNING! All tires should be replaced after six years, regard- less of the remaining tread. Failure to follow this warning can result in sudden tire failure. You could lose control and have an accident resulting in serious injury. Keep unmounted tires in a cool, dry place with as little exposure to light as possible. Protect tires from contact with oil, grease and gasoline. Replacement Tires The tires on your new vehicle provide a balance of many characteristics. They should be inspected regularly for wear and correct cold tire inflation pressure. The manu- facturer strongly recommends that you use tires equiva- lent to the originals in size, quality and performance when replacement is needed (see the paragraph on tread wear indicators). Refer to the Tire and Loading Informa- tion placard for the size designation of your tire. The service description and load identification will be found on the original equipment tire. Failure to use equivalent replacement tires may adversely affect the safety, han- dling, and ride of your vehicle. We recommend that you contact your original equipment or an authorized tire dealer with any questions you may have on tire specifi- cations or capability. STARTING AND OPERATING 265 WARNING! • Do not use a tire, wheel size or rating other than that specified for your vehicle. Some combinations of unapproved tires and wheels may change suspen- sion dimensions and performance characteristics, resulting in changes to steering, handling, and brak- ing of your vehicle. This can cause unpredictable handling and stress to steering and suspension com- ponents. You could lose control and have an accident resulting in serious injury or death. Use only the tire and wheel sizes with load ratings approved for your vehicle. • Never use a tire with a smaller load index or capacity, other than what was originally equipped on your vehicle. Using a tire with a smaller load index could result in tire overloading and failure. You could lose control and have an accident. • Failure to equip your vehicle with tires having adequate speed capability can result in sudden tire failure and loss of vehicle control. 266 STARTING AND OPERATING CAUTION! Replacing original tires with tires of a different size may result in false speedometer and odometer read- ings. Alignment and Balance Poor suspension alignment may result in: • Fast tire wear. • Uneven tire wear, such as feathering and one-sided • Vehicle pull to right or left. Tires may also cause the vehicle to pull left or right. Alignment will not correct this problem. See your autho- rized dealer for proper diagnosis. wear. Improper alignment will not cause vehicle vibration. Vibration may be a result of tire and wheel out-of- balance. Proper balancing will reduce vibration and avoid tire cupping and spotty wear. TIRE ROTATION RECOMMENDATIONS Do not rotate the tires as the wider rear tires will not fit on the front of the vehicle. TIRE PRESSURE MONITOR SYSTEM (TPMS) Premium System The Tire Pressure Monitor System (TPMS) uses wireless technology with wheel rim mounted electronic sensors to monitor tire pressure levels. Sensors mounted to each wheel as part of the valve stem transmit tire pressure readings to the Receiver Module. The wheel sensors monitor tire pressure, and status for all four active road tires. It is particularly important, for you to check the NOTE: tire pressure in all of your tires regularly and to maintain the proper pressure. The “Tire Pressure Monitoring Telltale Light” will illuminate in the instrument cluster, and an au- dible chime will be activated when one or more tire pressures is low. The “Tire Pressure Monitoring Telltale Light” will flash on and off for 60 seconds when a system fault is detected. The flash cycle will repeat every ten minutes or until the fault condition is removed and reset. The Tire Pressure Monitoring System (TPMS) consists of the following components: • Receiver Module • 4 Wheel Sensors • 3 Wheel Sensor Trigger Modules STARTING AND OPERATING 267 the EVIC • Tire Pressure Monitoring System Display Messages in • Tire Pressure Monitoring Telltale Light The system consists of tire pressure monitoring sensors attached to each wheel through the valve stem mounting hole, a central receiver module, Wheel Sensor Trigger Modules mounted in three of the four wheel wells, various Tire Pressure Monitoring System Display Mes- sages in the EVIC, and a “Tire Pressure Monitoring Telltale Light.” NOTE: For vehicles with optional wheel/tire sizes and significantly different tire placard pressures, the placard pressure value and the low-pressure threshold value is re-programmable at your authorized dealer to accommo- date the customer selected wheel/tire combinations rec- ommended by DaimlerChrysler Corporation. 268 STARTING AND OPERATING The following ⬙warnings⬙ will cause a text message to be displayed, an audible chime to sound, and the “Tire Pressure Monitoring Telltale Light” to illuminate. The audible chime will occur once every ignition cycle for each ⬙warning⬙ detected. The “Tire Pressure Monitoring Telltale Light” will illuminate continuously (solid) and shall remain illuminated until the warning condition is removed/reset. When the appropriate conditions exist, the Electronic Vehicle Information Center (EVIC) displays the following messages. LEFT FRONT, LEFT REAR, RIGHT FRONT, RIGHT REAR LOW PRESSURE One or more of these messages will be displayed in the EVIC if a low tire pressure condition exists in one or more tires. Inspect all tires for proper inflation pressure, once the proper tire pressure has been set, the TPMS will reset automatically when the vehicle has been driven for at least 2 minutes at or above 15 mph (24 km/h). CHECK TPM SYSTEM See your authorized dealer when this message appears in the EVIC. This message indicates that a system fault condition has been detected. CAUTION! CAUTION! STARTING AND OPERATING 269 The TPMS has been optimized for the original equipment tires and wheels. TPMS pressures have been established for the tire size equipped on your vehicle. Undesirable system operation or sensor damage may result when using replacement equip- ment that is not of the same size, type, and/or style. After-market wheels can cause sensor damage. Do not use tire sealant from a can, or balance beads if your vehicle is equipped with a TPMS, as damage to the sensors may result. After inspecting or adjusting the tire pressure al- ways reinstall the valve stem cap. This will prevent moisture and dirt from entering the valve stem, which could damage the wheel rim sensor. condition. NOTE: • The TPMS can inform the driver of a low tire pressure • The TPMS is not intended to replace normal tire care and maintenance, nor to provide warning of a tire failure or condition. • The TPMS should not be used as a tire pressure gauge while adjusting your tire pressure. 270 STARTING AND OPERATING General Information This device complies with part 15 of the FCC rules and RSS 210 of Industry Canada.

KR5S120123 Canada . . . . . . . . . . . . . . . . . . . . . . . . 2671-S120123 FUEL REQUIREMENTS Your vehicle is designed to meet all emis- sion regulations and provide excellent fuel economy when using high quality pre- mium unleaded gasoline having an octane rating of 91 or higher. Light spark knock at low engine speeds is not harmful to your engine. However, continued heavy spark knock at high speeds can cause damage and immediate service is required. Poor quality gasoline can cause problems such as hard starting, stalling and hesitations. If you experience these symptoms, try another brand of “premium” gasoline before considering service for the vehicle. Over 40 automobile manufacturers around the world have issued and endorsed consistent gasoline specifica- tions (the World Wide Fuel Charter, WWFC) to define fuel properties necessary to deliver enhanced emissions, engine performance, and durability for your vehicle. The manufacturer recommends the use of gasolines that meet the WWFC specifications if they are available. Reformulated Gasoline Many areas of the country require the use of cleaner burning gasoline referred to as “Reformulated Gasoline.” Reformulated gasolines contain oxygenates, and are spe- cifically blended to reduce vehicle emissions and im- prove air quality. The manufacturer supports the use of reformulated gaso- lines. Properly blended reformulated gasolines will pro- vide excellent performance and durability of engine and fuel system components. STARTING AND OPERATING 271 Gasoline/Oxygenate Blends Some fuel suppliers blend unleaded gasoline with oxy- genates such as 10% ethanol, MTBE, and ETBE. Oxygen- ates are required in some areas of the country during the winter months to reduce carbon monoxide emissions. Fuels blended with these oxygenates may be used in your vehicle. CAUTION! DO NOT use gasolines containing Methanol or E85 Ethanol. Use of these blends may result in starting and driveability problems and may damage critical fuel system components. Problems that result from using methanol/gasoline or E85 Ethanol blends are not the responsibility of the 272 STARTING AND OPERATING manufacturer. While MTBE is an oxygenate made from Methanol, it does not have the negative effects of Metha- nol. MMT In Gasoline MMT is a manganese containing metallic additive that is blended into some gasoline to increase the octane num- ber. Gasolines blended with MMT offer no performance advantage beyond gasolines of the same octane number without MMT. Gasolines blended with MMT have shown to reduce spark plug life and reduce emission system performance in some vehicles. The manufacturer recom- mends using gasolines without MMT. Since the MMT content of gasoline may not be indicated on the pump, you should ask your gasoline retailer whether or not his/her gasoline contains MMT. It is even more important to look for gasolines without MMT in Canada, because MMT can be used at levels higher than those allowed in the United States. MMT is prohibited in Federal and California reformu- lated gasolines. Materials Added to Fuel All gasoline sold in the United States is required to contain effective detergent additives. Use of additional detergents or other additives are not needed under normal conditions and would result in additional cost. Therefore you should not have to add anything to the fuel. Fuel System Cautions CAUTION! Follow these guidelines to maintain your vehicle’s performance: • The use of leaded gas is prohibited by Federal law. Using leaded gasoline can impair engine performance, or damage the emission control system. • An out-of-tune engine, or certain fuel or ignition malfunctions, can cause the catalytic converter to overheat. If you notice a pungent burning odor or some light smoke, your engine may be out-of-tune or malfunctioning and may require immediate service. Contact your dealer for service assistance. • The use of fuel additives which are now being sold as octane enhancers are not recommended. Most of these STARTING AND OPERATING 273 products contain high concentrations of methanol. Fuel system damage or vehicle performance problems resulting from the use of such fuels or additives are not the responsibility of the manufacturer. Intentional tampering with emissions control in civil penalties being assessed NOTE: systems can result against you. Carbon Monoxide Warnings WARNING! Carbon monoxide (CO) in exhaust gases is deadly. Follow the precautions below to prevent carbon monoxide poisoning: • Do not inhale exhaust gases. They contain carbon monoxide, a colorless and odorless gas which can kill. Never run the engine in a closed area, such as a 274 STARTING AND OPERATING garage, and never sit in a parked vehicle with the engine running for an extended period. If the vehicle is stopped in an open area with the engine running for more than a short period, adjust the ventilation system to force fresh, outside air into the vehicle. • Guard against carbon monoxide with proper mainte- nance. Have the exhaust system inspected every time the vehicle is raised. Have any abnormal conditions repaired promptly. Until repaired, drive with all side windows fully open. • Keep the liftgate closed when driving your vehicle to prevent carbon monoxide and other poisonous ex- haust gases from entering the vehicle. ADDING FUEL Fuel Filler Cap (Gas Cap) The gas cap is located behind the fuel filler door, on the driver’s side of the vehicle. If the gas cap is lost or damaged, be sure the replacement cap is for use with this vehicle. Fuel Filler Cap Location CAUTION! CAUTION! STARTING AND OPERATING 275 Damage to the fuel system or emission control system could result from using an improper fuel cap (gas cap). A poorly fitting cap could let impurities into the fuel system. Also, a poorly fitting after- market cap can cause the MIL (Malfunction Indica- tor Light) to illuminate, due to fuel vapors escaping from the system. CAUTION! A poorly fitting gas cap may cause the Malfunction Indicator Light to turn on. To avoid fuel spillage and overfilling, do not “top off” the fuel tank after filling. NOTE: When the fuel nozzle “clicks” or shuts off, the fuel tank is full. WARNING! • Never have any smoking materials lit in or near the vehicle when the gas cap is removed or the tank filled. • Never add fuel when the engine is running. This is in violation of most state and federal fire regulations and will cause the malfunction indi- cator light to turn on. 276 STARTING AND OPERATING NOTE: Tighten the gas cap about 1/4 turn until you hear one click. This is an indication that cap is properly tightened. If the gas cap is not tighten properly, the Malfunction Indicator Light will come on. Be sure the gas cap is tightened every time the vehicle is refueled. EVIC (Electronic Vehicle Information Center). Refer to “Electronic Vehicle Information Center” in Section 4 of this manual. Tighten the fuel filler cap until a “clicking” sound is heard. This is an indication that the fuel filler cap is properly tightened. Refer to “Onboard Diagnostic System — OBDII” in Section 7 of this manual for more information. WARNING! A fire may result if gasoline is pumped into a portable container that is inside of a vehicle. You could be burned. Always place gas containers on the ground while filling. Loose Fuel Filler Cap Message If the vehicle diagnostic system determines that the fuel filler cap is loose, improperly installed, or damaged, a “CHECK GASCAP” message will be displayed in the CAUTION! Damage to the fuel system or emission control system could result from using an improper fuel tank filler cap (gas cap). A poorly fitting cap could let impurities into the fuel system. WARNING! • Never add fuel when the engine is running. • Never have any smoking materials lit in or near the vehicle when the fuel cap is removed or the tank filled. TRAILER TOWING In this section you will find safety tips and information on limits to the type of towing you can reasonably do with your vehicle. Before towing a trailer carefully re- view this information to tow your load as efficiently and safely as possible. To maintain warranty coverage, follow the requirements and recommendations in this manual concerning ve- hicles used for trailer towing. STARTING AND OPERATING 277 Common Towing Definitions The following trailer towing related definitions will assist you in understanding the following information: Gross Vehicle Weight Rating (GVWR) The GVWR is the total allowable weight of your vehicle. This includes driver, passengers, cargo and tongue weight. The total load must be limited so that you do not exceed the GVWR. Gross Trailer Weight (GTW) The gross trailer weight (GTW) is the weight of the trailer plus the weight of all cargo, consumables and equipment (permanent or temporary) loaded in or on the trailer in its ⬙loaded and ready for operation⬙ condition. The recom- mended way to measure GTW is to put your fully loaded trailer on a vehicle scale. The entire weight of the trailer must be supported by the scale. 278 STARTING AND OPERATING Gross Combination Weight Rating (GCWR) The gross combination weight rating (GCWR) is the total permissible weight of your vehicle and trailer when weighed in combination. (Note that GCWR ratings in- clude a 150 lbs (68 kg) allowance for the presence of a driver). Gross Axle Weight Rating (GAWR) The GAWR is the maximum capacity of the front and rear axles. Distribute the load over the front and rear axles evenly. Make sure that you do not exceed either front or rear GAWR. WARNING! It is important that you do not exceed the maximum front or rear GAWR. A dangerous driving condition can result if either rating is exceeded. You could lose control of the vehicle and have an accident. Tongue Weight (TW) The downward force exerted on the hitch ball by the trailer. In most cases it should not be less than 10% or more than 15% of the trailer load. You must consider this as part of the load on your vehicle. Frontal Area The maximum height and maximum width of the front of a trailer. Trailer Sway Control The trailer sway control is a telescoping link that can be installed between the hitch receiver and the trailer tongue that typically provides adjustable friction associated with the telescoping motion to dampen any unwanted trailer swaying motions while traveling. Weight-Carrying Hitch A weight-carrying hitch supports the trailer tongue weight, just as if it were luggage located at a hitch ball or some other connecting point of the vehicle. These kind of STARTING AND OPERATING 279 WARNING! An improperly adjusted Weight Distributing Hitch system may reduce handling, stability, braking per- formance, and could result in an accident. Weight Distributing Systems may not be compatible with Surge Brake Couplers. Consult with your hitch and trailer manufacturer or a reputable Recreational Vehicle dealer for additional information. hitches are the most popular on the market today and they’re commonly used to tow small- and medium-sized trailers. Weight-Distributing Hitch A weight-distributing system works by applying lever- age through spring (load) bars. They are typically used for heavier loads, to distribute trailer tongue weight to the tow vehicle’s front axle and the trailer axle(s). When used in accordance with the manufacturers’ directions, it provides for a more level ride, offering more consistent steering and brake control thereby enhancing towing safety. The addition of a friction/hydraulic sway control also dampens sway caused by traffic and crosswinds and contributes positively to tow vehicle and trailer stability. Trailer sway control and a weight distributing (load equalizing) hitch are recommended for heavier Tongue Weights (TW) and may be required depending on Vehicle and Trailer configuration/loading to comply with gross axle weight rating (GAWR) requirements. 280 STARTING AND OPERATING Weight Distributing Hitch System Improper Adjustment of Weight Distributing System Trailer Hitch Classification Your vehicle may be factory equipped for safe towing of trailers weighing over 3,500 lbs (1 587 kg) with the optional Trailer Tow Prep Package. See your dealer for package content. The following chart provides the industry standard for the maximum trailer weight a given trailer hitch class can tow and should be used to assist you in selecting the correct trailer hitch for your intended towing condition. Refer to the Trailer Towing Weights (Maximum Trailer Weight Ratings) chart for the Max. GTW towable for your given drivetrain. STARTING AND OPERATING 281 Trailer Hitch Classification Class Max. GTW (Gross Trailer Wt.) 2,000 lbs (907 kg) 3,500 lbs (1 587 kg) Class I - Light Duty Class II - Medium Duty Class III - Heavy Duty Class IV - Extra Heavy Duty All trailer hitches should be professionally installed on your vehicle. 5,000 lbs (2 268 kg) 10,000 lbs (4 540 kg)
