For example, your vehicle has a recommended cold (parked for more than three hours) tire pressure of 33 psi (227 kPa). If the ambient temperature is 68°F (20°C) and the measured tire pressure is 28 psi (193 kPa), a tempera- ture drop to 20°F (-7°C) will decrease the tire pressure to approximately 24 psi (165 kPa). This tire pressure is sufficiently low enough to turn ON the Tire Pressure Monitoring Telltale Light. Driving the vehicle may cause the tire pressure to rise to approximately 28 psi (193 kPa), but the Tire Pressure Monitoring Telltale Light will still be ON. In this situation, the Tire Pressure Monitoring Telltale Light will turn OFF only after the tires have been inflated to the vehicle’s recommended cold tire pressure value.


CAUTION!


• 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 equipment that is not of the same size, type, and/or style. Aftermarket wheels can cause sensor dam- age. Do not use aftermarket tire sealants 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 always reinstall the valve stem cap. This will prevent moisture and dirt from entering the valve stem, which could damage the Tire Pressure Moni- toring Sensor.

while adjusting your tire pressure.


NOTE: • The TPMS is not intended to replace normal tire care and maintenance, or to provide warning of a tire failure or condition. • The TPMS should not be used as a tire pressure gauge • Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle’s handling and stopping ability. • The TPMS is not a substitute for proper tire mainte- nance, and it is the driver’s responsibility to maintain correct tire pressure using an accurate tire gauge, even if under-inflation has not reached the level to trigger illumination of the Tire Pressure Monitoring Telltale Light.


306 STARTING AND OPERATING


• Seasonal temperature changes will affect tire pressure, and the TPMS will monitor the actual tire pressure in the tire.


Base 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. It is particularly important, for you to regularly NOTE: check the tire pressure in all of your tires, and to maintain the proper pressure. The TPMS consists of the following components: • Receiver Module • Four Tire Pressure Monitoring Sensors • Tire Pressure Monitoring Telltale Light


A tire pressure monitoring sensor is located in the spare wheel, if the vehicle is equipped with a matching full-size spare wheel and tire assembly. The matching full-size spare tire can be used in place of any of the four road tires. A low spare tire will not cause the Tire Pressure Monitoring Telltale Light to illuminate, a warning mes- sage to appear, or the chime to sound.


The Tire Pressure Monitoring Telltale Light will illuminate in the instrument cluster, a “TIRE LOW PRESSURE” message will display in the instru- ment cluster for 60 seconds, and an audible chime will be activated, when one or more of the four active road tire pressures are low. Should this occur, you should stop as soon as possible, check the inflation pressure of each tire on your vehicle, and inflate each tire to the vehicle’s recommended cold placard pressure value. The system will automatically update and the Tire Pressure Monitor- ing Telltale Light will extinguish, once the updated tire


pressures have been received. The vehicle may need to be driven for up to 20 minutes above 15 mph (24 km/h) to receive this information. The Tire Pressure Monitoring Telltale Light will flash on and off for 75 seconds, and remain on solid when a system fault is detected. In addition, a “CHECK TPM SYSTEM” message will be displayed for 75 seconds when a system fault is detected, and a chime will sound. If the ignition key is cycled, this sequence will repeat, provid- ing the system fault still exists. The Tire Pressure Moni- toring Telltale Light will turn off when the fault condition no longer exists. A system fault can occur by any of the following: 1. Jamming due to electronic devices or driving next to facilities emitting the same Radio Frequencies as the TPM sensors. 2. Installing some form of aftermarket window tinting that affects radio wave signals.


STARTING AND OPERATING 307
3. Lots of snow or ice around the wheels or wheel housings. 4. Using tire chains on the vehicle. 5. Using wheels/tires not equipped with TPM sensors. NOTE: • If your vehicle is equipped with a matching full-size spare wheel and tire assembly, it has a tire pressure monitoring sensor, and can be monitored by the Tire Pressure Monitoring System (TPMS). In the event that the matching full-size spare tire is swapped with a low pressure road tire, the next ignition key cycle will still show the Tire Pressure Monitoring Telltale Light to be ON, a “TIRE LOW PRESSURE” message will be displayed in the instrument cluster for 60 seconds, and a chime to sound. Driving the vehicle for up to 20 minutes above 15 mph (24 km/h) will turn OFF the Tire Pressure Monitoring Telltale Light as long as none of the road tires are below the low pressure warning threshold.


308 STARTING AND OPERATING


• If your vehicle is not equipped with a matching full-size spare wheel and tire assembly, it does not have a tire pressure monitoring sensor in the spare tire. The TPMS will not be able to monitor the tire pressure. If you install the spare tire, in place of a road tire, that has a pressure below the low-pressure warning limit, upon the next ignition key cycle, a chime will sound, a “TIRE LOW PRESSURE” message will be displayed in the instrument cluster for 60 seconds, and the Tire Pressure Monitoring Telltale Light will turn ON. After driving the vehicle for up to 20 minutes above 15 mph (25 km/h), the Tire Pressure Monitoring Telltale Light will flash on and off for 75 seconds and then remain on solid. In addition, a “CHECK TPM SYSTEM” message will be displayed for 75 seconds. For each subsequent ignition key cycle, a chime will sound, a “CHECK TPM SYSTEM” message will be displayed for 75 sec- onds, and the Tire Pressure Monitoring Telltale Light will flash on and off for 75 seconds and then remain on


solid. Once you repair or replace the original road tire, and reinstall it on the vehicle in place of the spare tire, the TPMS will update automatically and the Tire Pressure Monitoring Telltale Light will turn OFF, as long as no tire pressure is below the low-pressure warning limit in any of the four active road tires. The vehicle may need to be driven for up to 20 minutes above 15 mph (24 km/h) in order for the TPMS to receive this information.


Premium System — If Equipped The Tire Pressure Monitor System (TPMS) uses wireless technology with wheel rim-mounted electronic sensors to monitor tire pressure levels.

314 STARTING AND OPERATING FUEL REQUIREMENTS


3.7 Engine


All engines (except 5.7L engines) are de- signed to meet all emissions regulations and provide excellent fuel economy and performance when using high-quality un- leaded “regular” gasoline having an oc- tane rating of 87. The use of premium gasoline is not recommended, as it will not provide any benefit over regular gasoline in these engines. 5.7L Engine


The 5.7L engine is designed to meet all emissions regulations and provide satisfac- tory fuel economy and performance when using high-quality unleaded gasoline hav- ing an octane range of 87 to 89. The manu- facturer recommends the use of 89 octane


for optimum performance. The use of premium gasoline is not recommended, as it will not provide any benefit over regular gasoline in these engines. 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 gasoline before consid- ering service for the vehicle. Over 40 auto manufacturers worldwide have issued and endorsed consistent gasoline specifications (the World- wide Fuel Charter, WWFC) to define fuel properties necessary to deliver enhanced emissions, performance, and durability for your vehicle. The manufacturer recom- mends the use of gasoline that meets the WWFC speci- fications, if they are available.


Reformulated Gasoline Many areas of the country require the use of cleaner burning gasoline referred to as “Reformulated Gasoline.” Reformulated gasoline contains oxygenates, and are spe- cifically blended to reduce vehicle emissions and im- prove air quality. The manufacturer supports the use of reformulated gaso- line. Properly blended reformulated gasoline will pro- vide excellent performance and durability of engine and fuel system components. 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.


STARTING AND OPERATING 315


CAUTION!


DO NOT use gasoline containing Methanol. Use of these blends may result in starting and drivability problems and may damage critical fuel system com- ponents.


Problems that result from using Methanol/gasoline blends are not the responsibility of the manufacturer. While MTBE is an oxygenate made from Methanol, it does not have the negative effects of Methanol. E-85 Usage In Non-Flex Fuel Vehicles Non-FFV vehicles are compatible with gasoline contain- ing 10% Ethanol (E10). Gasoline with higher Ethanol content may void the vehicle’s warranty. If a Non-FFV vehicle is inadvertently fueled with E-85
fuel, the engine will have some or all of these symptoms: • operate in a lean mode


316 STARTING AND OPERATING


• OBD II “Malfunction Indicator Light” on • poor engine performance • poor cold start and cold drivability • increased risk for fuel system component corrosion To fix a Non-FFV vehicle inadvertently fueled once with E-85 perform the following: • drain the fuel tank (see your authorized dealer) • change the engine oil and oil filter • disconnect and reconnect the battery to reset the


engine controller memory


More extensive repairs will be required for prolonged exposure to E-85 fuel. MMT In Gasoline MMT is a manganese containing metallic additive that is blended into some gasoline to increase octane. Gasoline


blended with MMT provides no performance advantage beyond gasoline of the same octane number without MMT. Gasoline blended with MMT reduces spark plug life and reduces emission system performance in some vehicles. The manufacturer recommends that gasoline without MMT be used in your vehicle. The MMT content of gasoline may not be indicated on the gasoline pump, therefore, you should ask your gasoline retailer if the gasoline contains MMT. It is even more important to look for gasoline 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 gasoline. 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 is 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 and 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 authorized dealer for service assistance.


STARTING AND OPERATING 317


• The use of fuel additives which are now being sold as octane enhancers is not recommended. Most of these products contain high concentrations of Methanol. Fuel system damage or vehicle performance problems resulting from the use of such fuels or additives is 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.


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.


318 STARTING AND OPERATING


• 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 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.


Fuel Filler Cap


CAUTION!


• 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 impu- rities into the fuel system. Also, a poorly fitting aftermarket cap can cause the “Malfunction Indi- cator Light” (MIL) to illuminate, due to fuel vapors escaping from the system. • A poorly fitting gas cap may cause the MIL to turn • To avoid fuel spillage and overfilling, do not “top


on.


off” the fuel tank after filling.


NOTE: When the fuel nozzle “clicks” or shuts off, the fuel tank is full.


STARTING AND OPERATING 319


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 regula- tions and will cause the MIL to turn on.


NOTE: Tighten the gas cap about one–quarter turn until you hear one click. This is an indication that cap is properly tightened. If the gas cap is not tighten properly, the MIL will come on. Be sure the gas cap is tightened every time the vehicle is refueled.


320 STARTING AND OPERATING 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 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.


CAUTION!


Damage to the fuel system or emission control sys- tem 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.


VEHICLE LOADING


Certification Label As required by National Highway Traffic Safety Admin- istration regulations, your vehicle has a certification label affixed to the driver’s side door or B-Pillar.


This label contains the month and year of manufacture, Gross Vehicle Weight Rating (GVWR), Gross Axle Weight Rating (GAWR) front and rear, and Vehicle Identification Number (VIN). A Month-Day-Hour (MDH) number is included on this label and indicates the month, day, and hour of manufacture. The bar code that appears on the bottom of the label is your VIN. Gross Vehicle Weight Rating (GVWR) The GVWR is the total permissible weight of your vehicle including driver, passengers, vehicle, options, trailer tongue weight, and cargo. The label also specifies maxi- mum capacities of front and rear axle systems (GAWR). Total load must be limited, so GVWR, and front and rear GAWR are not exceeded. Payload The payload of a vehicle is defined as the allowable load weight a truck can carry, including the weight of the driver, all passengers, options and cargo.


STARTING AND OPERATING 321


Gross Axle Weight Rating (GAWR) The GAWR is the maximum permissible load on the front and rear axles. The load must be distributed in the cargo area so that the GAWR of each axle is not exceeded. Each axle’s GAWR is determined by the components in the system with the lowest load carrying capacity (axle, springs, tires, or wheels). Heavier axles or suspension components, sometimes specified by purchasers for in- creased durability, does not necessarily increase the ve- hicle’s GVWR. Tire Size The tire size on the label represents the actual tire size on your vehicle. Replacement tires must be equal to the load capacity of this tire size. Rim Size This is the rim size that is appropriate for the tire size listed.


322 STARTING AND OPERATING Inflation Pressure This is the cold tire inflation pressure for your vehicle for all loading conditions up to full GAWR. Curb Weight The curb weight of a vehicle is defined as the total weight of the vehicle with all fluids, including vehicle fuel, at full capacity conditions, and with no occupants or cargo loaded into the vehicle. The front and rear curb weight values are determined by weighing your vehicle on a commercial scale before any occupants or cargo are added. Loading The actual total weight and the weight of the front and rear of your vehicle at the ground can best be determined by weighing it when it is loaded and ready for operation. The entire vehicle should first be weighed on a commer- cial scale to ensure that the GVWR has not been ex- ceeded. The weight on the front and rear of the vehicle


should then be determined separately to be sure that the load is properly distributed over front and rear axle. Weighing the vehicle may show that the GAWR of either the front or rear axles has been exceeded, but the total load is within the specified GVWR. If so, weight must be shifted from front to rear, or rear to front, as appropriate until the specified weight limitations are met. Store the heavier items down low and be sure that the weight is distributed equally. Stow all loose items securely before driving. Improper weight distributions can have an adverse affect on the way your vehicle steers and handles, and the way the brakes operate.


CAUTION!


Do not load your vehicle any heavier than the GVWR or the maximum front and rear GAWR. If you do, parts on your vehicle can break, or it can change the way your vehicle handles. This could cause you to lose control. Also, overloading can shorten the life of your vehicle.


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 323


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 trailer tongue weight. The total load must be limited so that you do not exceed the GVWR. Gross Trailer Weight (GTW) The GTW is the weight of the trailer plus the weight of all cargo, consumables and equipment (permanent or tem- porary) loaded in or on the trailer in its ⬙loaded and ready for operation⬙ condition. The recommended 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.


324 STARTING AND OPERATING Gross Combination Weight Rating (GCWR) The GCWR is the total permissible weight of your vehicle and trailer when weighed in combination. NOTE: The GCWR rating includes 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.


Trailer Tongue Weight (TW) The TW is 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 frontal area is the maximum height and maximum width of the front of a trailer. 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 hitches are the most popular on the market today and they are commonly used to tow small- and medium- sized trailers.


STARTING AND OPERATING 325


WARNING!


• An improperly adjusted weight-distributing hitch system may reduce handling, stability, and brak- ing performance, and could result in an accident. • Weight-distributing hitch systems may not be compatible with Surge Brake Couplers. Consult with your hitch and trailer manufacturer or a reputable Recreational Vehicle dealer for addi- tional information.


Weight-Distributing Hitch A weight-distributing hitch system works by applying leverage 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 manufacturer’s direc- tions, 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 cross- winds, and contributes positively to tow vehicle and trailer stability. Trailer sway control and a weight distrib- uting (load equalizing) hitch are recommended for heavier trailer tongue weights (TW) and may be required depending on Vehicle and Trailer configuration/loading to comply with gross axle weight rating (GAWR) requirements.

NOTE: The trailer tongue weight must be considered as part of the combined weight of occupants and cargo, and should never exceed the weight referenced on the Tire and Loading Information placard. Refer to the “Tire– Safety Information” section in this manual. Trailer And Tongue Weight Always load a trailer with 60% to 65% of the weight in the front of the trailer. This places 10% to 15% of the Gross Trailer Weight (GTW) on the tow hitch of your vehicle. Loads balanced over the wheels, or heavier in the rear, can cause the trailer to sway severely side-to-side which will cause loss of control of vehicle and trailer. Failure to load trailers heavier in front is the cause of many trailer accidents.


STARTING AND OPERATING 329


Consider the following items when computing the weight on the front/rear axles of the vehicle: • The tongue weight of the trailer. • The weight of any other type of cargo or equipment • The weight of the driver and all passengers.


put in or on your vehicle.


330 STARTING AND OPERATING NOTE: Remember that everything put into or on the trailer adds to the load on your vehicle. Also, additional factory-installed options, or dealer-installed options, must be considered as part of the total load on your vehicle. Refer to the Tire and Loading Information plac- ard in the “Tire—Safety Information” section of this manual for the maximum combined weight of occupants and cargo for your vehicle. Towing Requirements To promote proper break-in of your new vehicle drive- train components the following guidelines are recom- mended:


CAUTION!


• Avoid towing a trailer for the first 500 miles (805 km) of vehicle operation. Doing so may dam- age your vehicle.


(Continued)


CAUTION! (Continued)


• During the first 500 miles (805 km) of trailer


towing, limit your speed to 50 mph (80 km/h).


WARNING!


Improper towing can lead to an injury accident. Follow these guidelines to make your trailer towing as safe as possible: Make certain that the load is secured in the trailer and will not shift during travel. When trailering cargo that is not fully secured, dynamic load shifts can occur that may be difficult for the driver to control. You could lose control of your vehicle and have an accident.


• When hauling cargo or towing a trailer, do not over- load your vehicle or trailer. Overloading can cause a loss of control, poor performance or damage to brakes, axle, engine, transmission, steering, suspension, chas- sis structure or tires. • Safety chains must always be used between your vehicle and trailer. Always connect the chains to the hook retainers of the vehicle hitch. Cross the chains under the trailer tongue and allow enough slack for turning corners. • Vehicles with trailers should not be parked on a grade. When parking, apply the parking brake on the tow vehicle. Put the tow vehicle transmission in PARK. For four-wheel drive vehicles, make sure the transfer case is not in NEUTRAL. Always, block or ⬙chock⬙ the trailer wheels.


• GCWR must not be exceeded.


STARTING AND OPERATING 331


• Total weight must be distributed between the tow vehicle and the trailer such that the following four ratings are not exceeded: 1. GVWR 2. GTW 3. GAWR 4. Trailer tongue weight rating for the trailer hitch utilized (This requirement may limit the ability to always achieve the 10% to 15% range of tongue weight as a percentage of total trailer weight).


Towing Requirements — Tires − Do not attempt to tow a trailer while using a compact


spare tire.


− Proper tire inflation pressures are essential to the safe and satisfactory operation of your vehicle. Refer to “Tires–General Information” in this section.


332 STARTING AND OPERATING − Check the trailer tires for proper tire inflation pres-


sures before trailer usage.


− Check for signs of tire wear or visible tire damage before towing a trailer. Refer to “Tires–General Infor- mation” in this section.


− When replacing tires, refer to “Tires–General Informa- tion” in this section. Replacing tires with a higher load carrying capacity will not increase the vehicle’s GVWR and GAWR limits.


Towing Requirements — Trailer Brakes − Do not interconnect the hydraulic brake system or vacuum system of your vehicle with that of the trailer. This could cause inadequate braking and possible personal injury.


− An electronically-actuated trailer brake controller is required when towing a trailer with electronically- actuated brakes. When towing a trailer equipped with a hydraulic surge-actuated brake system, an electronic brake controller is not required.


− Trailer brakes are recommended for trailers over 1,000 lbs (454 kg) and required for trailers in excess of 2,000 lbs (907 kg).


CAUTION!


If the trailer weighs more than 1,000 lbs (454 kg) loaded, it should have its own brakes and they should be of adequate capacity. Failure to do this could lead to accelerated brake lining wear, higher brake pedal effort, and longer stopping distances.


STARTING AND OPERATING 333
The Trailer Tow Package includes a seven–pin connector at the rear of the vehicle and a four-pin harness located under the rear bumper. The four-pin harness must be unclipped before use. Use a factory-approved trailer harness and connector. The electrical connections are all complete to the vehicle but you must mate the harness to a trailer connector. Refer to the following illustrations.


WARNING!


• Do not connect trailer brakes to your vehicle’s hydraulic brake lines. It can overload your brake system and cause it to fail. You might not have brakes when you need them and could have an accident. • Towing any trailer will increase your stopping distance. When towing, you should allow for ad- ditional space between your vehicle and the ve- hicle in front of you. Failure to do so could result in an accident.


Towing Requirements — Trailer Lights and Wiring Whenever you pull a trailer, regardless of the trailer size, stop lights and turn signals on the trailer are required for motoring safety.

Towing Tips Before setting out on a trip, practice turning, stopping and backing the trailer in an area away from heavy traffic. Automatic Transmission The DRIVE range can be selected when towing. How- ever, if frequent shifting occurs while in this range, the TOW/HAUL mode (if equipped) or a lower gear range should be selected. NOTE: Using the TOW/HAUL mode (if equipped) or a lower gear range while operating the vehicle under heavy operating conditions, will improve performance and extend transmission life by reducing excessive shift- ing and heat buildup. This action will also provide better engine braking.


STARTING AND OPERATING 335
The transmission fluid and filter should be changed if you REGULARLY tow a trailer for more than 45 minutes of continuous operation. Refer to the “Maintenance Schedule” in Section 8 for the proper maintenance inter- vals. NOTE: Check the transmission fluid level before towing (5.7L engine). Electronic Speed Control — If Equipped − Do not use in hilly terrain or with heavy loads. − When using the speed control, if you experience speed drops greater than 10 mph (16 km/h), disengage until you can get back to cruising speed.


− Use speed control in flat terrain and with light loads to


maximize fuel efficiency.


336 STARTING AND OPERATING Cooling System To reduce potential for engine and transmission over- heating, take the following actions: − City Driving When stopped for short periods of time, shift the trans- mission into NEUTRAL and increase engine idle speed. − Highway Driving Reduce speed. − Air Conditioning Turn off temporarily.


SNOW PLOW Snow plows, winches, and other aftermarket equipment should not be added to the front end of your vehicle. The airbag crash sensors may be affected by the change in the front end structure. The airbags could deploy unexpect- edly or could fail to deploy during a collision.


WARNING!


Do not add a snow plow, winches, or any other aftermarket equipment to the front of your vehicle. This could adversely affect the functioning of the airbag system and you could be injured.


RECREATIONAL TOWING (BEHIND MOTORHOME, ETC.)


Towing – Two-Wheel Drive Models


Recreational towing is allowed ONLY if the driveshaft is removed. Towing with the rear wheels on the ground while the driveshaft is connected can result in severe transmission damage.


Towing — Quadra-Trac I姞 (Single-Speed Transfer Case) Four-Wheel Drive Models


Recreational towing is not allowed. This model does not have a NEUTRAL position in the transfer case. Towing — Quadra–Trac II姞 /Quadra–Drive姞 II Four-Wheel Drive Models


CAUTION!


Front or rear wheel lifts should not be used. Internal damage to the transmission or transfer case will occur if a front or rear wheel lift is used when recreational towing.


NOTE: The transfer case must be in the NEUTRAL position, and the transmission must be in the PARK position for recreational towing.


STARTING AND OPERATING 337

342 WHAT TO DO IN EMERGENCIES HAZARD WARNING FLASHERS The Hazard Warning flasher switch is located on the switch bank just above the climate controls.


Press the switch to turn on the Hazard Warning flasher. When the switch is activated, all directional turn signals will flash on and off to warn oncoming traffic of an emergency. Press the switch a second time to turn off the Hazard Warning flasher. This is an emergency warning system and should not be used when the vehicle is in motion. Use it when your vehicle is disabled and is creating a safety hazard for other motorists. If it is necessary to leave the vehicle to go for service, the Hazard Warning flasher will continue to operate with the ignition key removed and the vehicle locked. NOTE: With extended use, the Hazard Warning flasher may run down your battery.


IF YOUR ENGINE OVERHEATS In any of the following situations, you can reduce the potential for overheating by taking the appropriate ac- tion. • On the highways — Slow down. • In city traffic — While stopped, put the transmission in NEUTRAL, but do not increase the engine idle speed.


CAUTION!


Driving with a hot cooling system could damage your vehicle. If the temperature gauge reads HOT (H), pull over and stop the vehicle. Idle the vehicle with the air conditioner turned off until the pointer drops back into the normal range. If the pointer remains on HOT (H), and you hear continuous chimes, turn the engine off immediately and call for service.


NOTE: There are steps that you can take to slow down an impending overheat condition: • If your air conditioner (A/C) is on, turn it off. The A/C system adds heat to the engine cooling system and turning the A/C off can help remove this heat. • You can also turn the Temperature Control to maxi- mum heat, the Mode Control to floor and the Blower Control to high. This allows the heater core to act as a supplement to the radiator and aids in removing heat from the engine cooling system.


JACKING AND TIRE CHANGING


WHAT TO DO IN EMERGENCIES 343


WARNING!


• Getting under a jacked-up vehicle is dangerous. The vehicle could slip off the jack and fall on you. You could be crushed. Never get any part of your body under a vehicle that is on a jack. If you need to get under a raised vehicle, take it to a service center where it can be raised on a lift. • The jack is a tool for changing tires only. The jack should not be used to lift the vehicle for service purposes. The vehicle should be jacked on a firm level surface only. Avoid ice or slippery areas.


344 WHAT TO DO IN EMERGENCIES Jack Location The scissor-type jack and tire changing tools are located in a compartment behind the third row seat. Refer to “Cargo Area Features” in Section 3 for further informa- tion.


Spare Tire Stowage The spare tire is stowed under the rear of the vehicle by means of a cable winch mechanism. To remove or stow the spare, use the jack handle to rotate the “spare tire drive” nut. The nut is located under a plastic cover at the center-rear of the cargo floor area, just inside the liftgate opening.


CAUTION!


Do not use power tools to winch the tire up or down. Impact type tools can damage the winch mechanism.


Jack Storage Location


WHAT TO DO IN EMERGENCIES 345


CAUTION!


The winch mechanism is designed for use with the jack extension tube only. Use of an air wrench or other power tools is not recommended and can dam- age the winch.


When the spare is clear, tilt the retainer at the end of the cable and pull it through the center of the wheel. Preparations For Jacking


1. Park the vehicle on a firm, level surface. Avoid ice and slippery areas.


Lowering/Raising Spare Tire


Spare Tire Removal Fit the jack handle extension over the drive nut. Use the lug wrench to rotate the nut counterclockwise until the spare is on the ground with enough slack in the cable to allow pulling the tire out from under the vehicle.


346 WHAT TO DO IN EMERGENCIES


WARNING!


Do not attempt to change a tire on the side of the vehicle close to moving traffic. Pull far enough off the road to avoid being hit when operating the jack or changing the wheel.


2. Set the parking brake. 3. Place the shift lever into PARK 4. Turn OFF the ignition. 5. Turn on the Hazard Warning flasher.


6. Block both the front and rear of the wheel diagonally opposite of the jack- ing position. For example, if changing the right front tire, block the left rear wheel.


NOTE: Passengers should not remain in the vehicle when the vehicle is being jacked. Jacking Instructions

WHAT TO DO IN EMERGENCIES 349


WARNING!


Raising the vehicle higher than necessary can make the vehicle less stable. It could slip off the jack and hurt someone near it. Raise the vehicle only enough to remove the tire.


6. Remove the lug nuts and wheel. 7. Position the spare wheel/tire on the vehicle and install the lug nuts with the cone-shaped end toward the wheel. Lightly tighten the nuts. To avoid the risk of forcing the vehicle off the jack, do not tighten the nuts fully until the vehicle has been lowered. 8. Lower the vehicle by turning the jack screw counter- clockwise, and remove the jack and wheel blocks.


Rear Jacking Location


5. Raise the vehicle by turning the jack screw clockwise. Raise the vehicle only until the tire just clears the surface and enough clearance is obtained to install the spare tire. Minimum tire lift provides maximum stability.


350 WHAT TO DO IN EMERGENCIES 9. Finish tightening the lug nuts. Push down on the wrench while tightening for increased leverage. Alternate nuts until each nut has been tightened twice. The correct wheel nut tightness is 95 ft lbs (130 N·m). If in doubt about the correct tightness, have them checked with a torque wrench by your authorized dealer or at a service station. 10. Lower the jack to it’s fully closed position.


WARNING!


A loose tire or jack, thrown forward in a collision or hard stop could endanger the occupants of the ve- hicle. Always stow the jack parts and the spare tire in the places provided.


11. Secure the tire, jack, and tools in their proper loca- tions.


NOTE: Tire should be stowed with the “beauty” side up. Storing the tire upside down may result in scratching or damage to the wheel face. Continue winching up the tire until you hear the winch “ratchet” three times. Double check to ensure the tire is snug against the underbody of the vehicle. Damage to the winch cable may result if the vehicle is driven with the tire loose.


WARNING!


Do not use power tools to winch the tire up or down. Impact type tools may damage the winch mechanism.


12. Reinstall the rubber plug into the floor of the cargo area.


JUMP-STARTING 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, so follow this procedure carefully.


WARNING!


• Remove any metal jewelry such as watch bands or bracelets that might make an inadvertent electrical contact. You could be seriously injured. • Battery fluid is a corrosive acid solution that can cause serious burns; do not allow battery fluid to contact eyes, skin or clothing. Wear safety glasses and protect your eyes at all times. If acid splashes in eyes or on skin, flush contaminated area imme- diately with large quantities of water.

WHAT TO DO IN EMERGENCIES 351


WARNING! (Continued)


• A battery generates hydrogen gas which is flam- mable and explosive. Keep flame or spark away from the vent holes. Do not lean over the battery when attaching clamps or allow the clamps to touch each other. • Do not use a booster battery or any other booster source that has a greater than 12 Volt system, i.e., do not use a 24 Volt power source.


1. Remove all metal jewelry such as watch bands or bracelets, which might make an unintended electrical contact. 2. Park the booster vehicle within cable reach but with- out letting the vehicles touch. Set the parking brake on both vehicles, place the transmission in PARK and turn the ignition OFF.


352 WHAT TO DO IN EMERGENCIES 3. Turn off the heater, radio and all unnecessary electrical loads. 4. Connect one end of a jumper cable to the positive terminal of the booster battery. Connect the other end of the same cable to the positive terminal of the discharged battery.


WARNING!


• Do not permit vehicles to touch each other as this could establish a ground connection and personal injury could result. • Do not connect the cable to the negative post of the discharged battery. The resulting electrical spark could cause the battery to explode and could result in personal injury.


(Continued)


WARNING! (Continued)


• During cold weather when temperatures are be- low the freezing point, electrolyte in a discharged battery may freeze. Do not attempt jump-starting because the battery could rupture or explode and cause personal injury. Battery temperature must be brought above freezing point before attempting a jump-start.


5. Connect the other cable, first to the negative terminal of the booster battery and then to the engine of the vehicle with the discharged battery. Make sure you have a good contact on the engine. 6. Start the engine in the vehicle that has the booster battery, let the engine idle a few minutes, then start the engine in the vehicle with the discharged battery. 7. When removing the jumper cables, reverse the above sequence exactly. Be careful of the moving belts and fan.


WARNING!


Any procedure other than above could result in: • Personal injury caused by electrolyte squirting out • Personal injury or property damage due to battery

CAUTION!


Any procedure other than above could result in damage to the charging system of the booster vehicle or of the immobilized vehicle.


EMERGENCY TOW HOOKS — IF EQUIPPED If your vehicle is equipped with tow hooks, there will be one in the rear and two mounted on the front of the vehicle. The rear hook will be located on the driver’s side of the vehicle.


WHAT TO DO IN EMERGENCIES 353
NOTE: For off-road recovery, it is recommended to use both of the front tow hooks to minimize the risk of damage to the vehicle.


CAUTION!


Tow hooks are for emergency use only, to rescue a vehicle stranded off road. Do not use tow hooks for tow truck hookup or highway towing. You could damage your vehicle.


WARNING!


Stand clear of vehicles when pulling with tow hooks. Tow straps and chains may break, causing serious injury.


4–Wheel Drive Models Only The manufacturer requires towing your vehicle with all four wheels OFF the ground using a flatbed.


CAUTION!


Towing this vehicle using any other method could result in extensive damage to the transfer case and/or transmission.


354 WHAT TO DO IN EMERGENCIES TOWING A DISABLED VEHICLE


2–Wheel Drive Models Only Provided the transmission is operable, tow only in NEU- TRAL at speeds not exceeding 30 mph (48 km/h), for distances of not more than 15 miles (24 km).


CAUTION!


Towing at more than 30 mph (48 km/h) or for more than 15 miles (24 km), can cause severe transmission damage.


If the transmission is not operable, or the vehicle must be towed faster than 30 mph (48 km/h) or farther than 15 miles (24 km), remove the driveshaft or tow with all four wheels OFF the ground.

ONBOARD DIAGNOSTIC SYSTEM – OBD II Your vehicle is equipped with a sophisticated onboard diagnostic system called OBD II. This system monitors the performance of the emissions, engine, and automatic transmission control systems. When these systems are operating properly, your vehicle will provide excellent performance and fuel economy, as well as engine emis- sions well within current government regulations. If any of these systems require service, the OBD II system will turn on the “Malfunction Indicator Light” (MIL). It will also store diagnostic codes and other information to assist your service technician in making repairs. Al- though your vehicle will usually be drivable and not need towing, see your authorized dealer for service as soon as possible.


MAINTAINING YOUR VEHICLE 359


CAUTION!


• Prolonged driving with the MIL on could cause further damage to the emission control system. It could also affect fuel economy and drivability. The vehicle must be serviced before any emissions tests can be performed. • If the MIL is flashing while the engine is running, severe catalytic converter damage and power loss will soon occur. Immediate service is required.


Loose Fuel Filler Cap Message After fuel is added, the vehicle diagnostic system can determine if the fuel filler cap is loose, improperly installed, or damaged. A “CHECK GASCAP” message will be displayed in the EVIC (Refer to Section 4 of this manual). Tighten the gas cap until a ⬙clicking⬙ sound is heard. This is an indication that the gas cap is properly tightened.


360 MAINTAINING YOUR VEHICLE The message will remain displayed until the vehicle diagnostic system can retest the fuel system. The test will perform the next time the vehicle is started, if the vehicle was keyed off above 40°F (4°C) outside temperature and the following vehicle start is above 40°F (4°C) outside temperature. It may be possible to have a message that will not clear due to the test being disabled due to low outside temperatures. If the test is performed and the problem is gone, the message will disappear. If the problem persists, the message will appear the next time the vehicle is started. This might indicate a damaged cap. If the problem is detected twice in a row, the system will turn on the MIL. Resolving the problem will turn the MIL off. See your authorized dealer for service.


EMISSIONS INSPECTION AND MAINTENANCE PROGRAMS In some localities, it may be a legal requirement to pass an inspection of your vehicle’s emissions control system.


Failure to pass could prevent vehicle registration.


For states that require an Inspection and Mainte- nance (I/M), this check verifies the “Malfunction Indicator Light (MIL)” is functioning and is not on when the engine is running, and that the OBD II system is ready for testing. Normally, the OBD II system will be ready. The OBD II system may not be ready if your vehicle was recently serviced, recently had a dead battery or a battery replace- ment. If the OBD II system should be determined not ready for the I/M test, your vehicle may fail the test. Your vehicle has a simple ignition key-actuated test, which you can use prior to going to the test station. To check if your vehicle’s OBD II system is ready, you must do the following: 1. Insert your ignition key into the ignition switch.


2. Turn the ignition to the ON position, but do not crank or start the engine. 3. If you crank or start the engine, you will have to start this test over. 4. As soon as you turn your key to the ON position, you will see the MIL symbol come on as part of a normal bulb check. 5. Approximately 15 seconds later, one of two things will happen:


a. The MIL will flash for about 10 seconds and then return to being fully illuminated until you turn OFF the ignition or start the engine. This means that your vehicle’s OBD II system is not ready and you should not proceed to the I/M station.


MAINTAINING YOUR VEHICLE 361
b. The MIL will not flash at all and will remain fully illuminated until you turn OFF the ignition or start the engine. This means that your vehicle’s OBD II system is ready and you can proceed to the I/M station.


If your OBD II system is not ready, you should see your authorized dealer or repair facility. If your vehicle was recently serviced or had a battery failure or replacement, you may need to do nothing more than drive your vehicle as you normally would in order for your OBD II system to update. A recheck with the above test routine may then indicate that the system is now ready. Regardless of whether your vehicle’s OBD II system is ready or not, if the MIL is illuminated during normal vehicle operation you should have your vehicle serviced before going to the I/M station. The I/M station can fail your vehicle because the MIL is on with the engine running.


362 MAINTAINING YOUR VEHICLE REPLACEMENT PARTS Use of genuine MOPAR威 parts for normal/scheduled maintenance and repairs is highly recommended to en- sure the designed performance. Damage or failures caused by the use of non-MOPAR威 parts for maintenance and repairs will not be covered by the manufacturer’s warranty.


DEALER SERVICE Your authorized dealer has the qualified service person- nel, special tools, and equipment to perform all service operations in an expert manner. Service Manuals are available which include detailed service information for your vehicle. Refer to these manuals before attempting any procedure yourself. Intentional tampering with emissions control NOTE: systems may void your warranty and could result in civil penalties being assessed against you.


WARNING!


You can be badly injured working on or around a motor vehicle. Only do service work for which you have the knowledge and the proper equipment. If you have any doubt about your ability to perform a service job, take your vehicle to a competent me- chanic.


MAINTENANCE PROCEDURES The pages that follow contain the required maintenance services determined by the engineers who designed your vehicle. Besides those maintenance items specified in the fixed maintenance schedule, there are other components which may require servicing or replacement in the future.


CAUTION!


• Failure to properly maintain your vehicle or per- form repairs and service when necessary could result in more costly repairs, damage to other components or negatively impact vehicle perfor- mance. Immediately have potential malfunctions examined by an authorized Chrysler Group LLC dealership or qualified repair center. • Your vehicle has been built with improved fluids that protect the performance and durability of your vehicle and also allow extended maintenance intervals. Do not use chemical flushes in these components as the chemicals can damage your engine, transmission, power steering or air condi- tioning. Such damage is not covered by the New Vehicle Limited Warranty. If a flush is needed because of component malfunction, use only the specified fluid for the flushing procedure.

Engine Oil


Checking Oil Level To assure proper engine lubrication, the engine oil must be maintained at the correct level. Check the oil level at regular intervals, such as every fuel stop. The best time to check the engine oil level is about five minutes after a fully warmed engine is shut off, or before starting the engine after it has sat overnight. Checking the oil while the vehicle is on level ground will improve the accuracy of the oil level readings. Maintain the oil level in the SAFE level range. Adding 1 U.S. Quart (0.95L) of oil when the level is at the bottom of the SAFE range will result in the level being at the top of the SAFE range.


364 MAINTAINING YOUR VEHICLE


CAUTION!


Overfilling or underfilling the crankcase will cause aeration or loss of oil pressure. This could damage your engine.


Change Engine Oil The oil change indicator system will remind you that it is time to take your vehicle in for scheduled maintenance. Refer to the “Maintenance Schedule” in Section 8 for information on this system. NOTE: Under no circumstances should oil change intervals exceed 6,000 miles (10 000 km) or six months, whichever occurs first.


Engine Oil Selection For best performance and maximum protection for all engines under all types of operating conditions, the


manufacturer recommends engine oils that are API Cer- tified and meet the requirements of Chrysler Material Standard MS-6395. American Petroleum Institute (API) Engine Oil Identification Symbol


This symbol means that the oil has been certified by the American Petroleum Institute (API). The manufacturer only recommends API Certified engine oils.


CAUTION!


Do not use chemical flushes in your engine oil as the chemicals can damage your engine. Such damage is not covered by the New Vehicle Limited Warranty.


Engine Oil Viscosity SAE 5W-20 engine oil is recommended for all operating temperatures. This engine oil improves low temperature starting and vehicle fuel economy. The engine oil filler cap also shows the recommended engine oil viscosity for your vehicle. For information on engine oil filler cap location, refer to “Engine Compart- ment” in this section. NOTE: Vehicles equipped with a 5.7L engine must use SAE 5W-20 oil. Failure to do so may result in improper operation of the Multiple Displacement System (MDS). Refer to “Multi-Displacement System” in Section 5 for more details. Lubricants, which do not have both the engine oil certi- fication mark and the correct SAE viscosity grade num- ber, should not be used.


MAINTAINING YOUR VEHICLE 365


Synthetic Engine Oils You may use synthetic engine oils if the recommended oil quality requirements are met, and the recommended maintenance intervals for oil and filter changes are followed. Materials Added to Engine Oils The manufacturer strongly recommends against the ad- dition of any additives (other than leak detection dyes) to the engine oil. Engine oil is an engineered product and its performance may be impaired by supplemental additives. Disposing of Used Engine Oil and Oil Filters Care should be taken in disposing of used engine oil and oil filters from your vehicle. Used oil and oil filters, indiscriminately discarded, can present a problem to the


366 MAINTAINING YOUR VEHICLE environment. Contact your local authorized dealer, ser- vice station, or governmental agency for advice on how and where used oil and oil filters can be safely discarded in your area. Engine Oil Filter The engine oil filter should be replaced with a new filter at every oil change. Engine Oil Filter Selection The manufacturer’s engines have a full-flow type dispos- able oil filter. Use a filter of this type for replacement. The quality of replacement filters varies considerably. Only high-quality filters should be used to assure most effi- cient service. MOPAR威 engine oil filters are high-quality oil filters and are recommended. Engine Air Cleaner Filter Refer to the “Maintenance Schedule” in Section 8 for the proper maintenance intervals.


WARNING!


The air induction system (air cleaner, hoses, etc) can provide a measure of protection in the case of engine backfire. Do not remove the air induction system (air cleaner, hoses, etc.) unless such removal is necessary for repair or maintenance. Make sure that no one is near the engine compartment before starting the vehicle with the air induction system (air cleaner, hoses, etc.) removed. Failure to do so can result in serious personal injury.


Engine Air Cleaner Filter Selection The quality of replacement engine air cleaner filters varies considerably. Only high quality filters should be used to assure most efficient service. MOPAR威 engine air cleaner filters are a high quality filter and are recommended.


Maintenance-Free Battery Your vehicle is equipped with a maintenance-free battery. You will never have to add water, nor is periodic main- tenance required.


WARNING!


• Battery fluid is a corrosive acid solution and can burn or even blind you. Do not allow battery fluid to contact your eyes, skin or clothing. Do not lean over a battery when attaching clamps. If acid splashes in eyes or on skin, flush the area imme- diately with large amounts of water. • Battery gas is flammable and explosive. Keep flame or sparks away from the battery. Do not use a booster battery or any other booster source with an output greater than 12 Volts. Do not allow cable clamps to touch each other.


(Continued)


MAINTAINING YOUR VEHICLE 367


WARNING! (Continued)


• Battery posts, terminals and related accessories contain lead and lead compounds. Wash hands after handling.


CAUTION!


• It is essential when replacing the cables on the battery that the positive cable is attached to the positive post, and the negative cable is attached to the negative post. Battery posts are marked (+) positive and (-) negative and identified on the battery case. • If a “fast charger” is used while battery is in the vehicle, disconnect both vehicle battery cables before connecting the charger to the battery. Do not use a “fast charger” to provide starting voltage.


368 MAINTAINING YOUR VEHICLE Air Conditioner Maintenance For best possible performance, your air conditioner should be checked and serviced by an authorized dealer at the start of each warm season. This service should include cleaning of the condenser fins and a performance test. Drive belt condition should also be checked at this time.


CAUTION!


Do not use chemical flushes in your air conditioning system as the chemicals can damage your air condi- tioning components. Such damage is not covered by the New Vehicle Limited Warranty.


WARNING!


• Use only refrigerants and compressor lubricants approved by the manufacturer for your air condi- tioning system. Some unapproved refrigerants are flammable and can explode, injuring you. Other unapproved refrigerants or lubricants can cause the system to fail, requiring costly repairs. Refer to Section 3 of the Warranty Information book, lo- cated on the DVD, for further warranty informa- tion. • The air conditioning system contains refrigerant under high pressure. To avoid risk of personal injury or damage to the system, adding refrigerant or any repair requiring lines to be disconnected should be done by an experienced repairman.


NOTE: Use only manufacturer approved A/C System Sealers, Stop Leak Products, Seal Conditioners, Compres- sor Oil, and Refrigerants. Refrigerant Recovery and Recycling R-134a Air Conditioning Refrigerant is a hydrofluoro- carbon (HFC) that is endorsed by the Environmental Protection Agency (EPA) and is an ozone-saving product. However, the manufacturer recommends that air condi- tioning service be performed by authorized dealers or other service facilities using recovery and recycling equipment. Body Lubrication Locks and all body pivot points, including such items as seat tracks, door hinge pivot points and rollers, liftgate, tailgate, sliding doors and hood hinges, should be lubri- cated periodically with a lithium based grease, such as MOPAR威 Spray White Lube or equivalent to assure quiet, easy operation and to protect against rust and


MAINTAINING YOUR VEHICLE 369
wear. Prior to the application of any lubricant, the parts concerned should be wiped clean to remove dust and grit; after lubricating excess oil and grease should be removed. Particular attention should also be given to hood latching components to insure proper function. When performing other underhood services, the hood latch, release mechanism and safety catch should be cleaned and lubricated. The external lock cylinders should be lubricated twice a year, preferably in the Fall and Spring. Apply a small amount of a high quality lubricant, such as MOPAR威 Lock Cylinder Lubricant or equivalent directly into the lock cylinder. Windshield Wiper Blades Clean the rubber edges of the wiper blades and the windshield periodically with a sponge or soft cloth and a mild nonabrasive cleaner to remove accumulations of salt or road film.


370 MAINTAINING YOUR VEHICLE Operation of the wipers on dry glass for long periods may cause deterioration of the wiper blades. Always use washer fluid when using the wipers to remove salt or dirt from a dry windshield. Avoid using the wiper blades to wipe frost or ice from the windshield. Keep the blade rubber out of contact with petroleum products such as engine oil, gasoline, etc. NOTE: Life expectancy of wiper blades varies depend- ing on geographical area and frequency of use. Poor performance of blades may be present with chattering, marks, water lines or wet spots. If any condition is present please proceed to clean wiper blades with humid cloth removing any debris that may be affecting its function. Adding Washer Fluid On vehicles equipped with a Electronic Vehicle Informa- tion Center (EVIC), the low washer fluid level will be indicated. When the sensor detects a low fluid level, the


windshield will light on the vehicle graphic outline and the “WASHER FLUID LOW” message will be displayed. The fluid reservoir for the windshield washers and the rear window washer is shared. The fluid reservoir is located in the engine compartment, be sure to check the fluid level at regular intervals. Fill the reservoir with windshield washer solvent only (not radiator antifreeze). When refilling the washer fluid reservoir, take some washer fluid and apply it to a cloth or towel and wipe clean the wiper blades, this will help blade performance. To prevent freeze-up of your windshield washer system in cold weather, select a solution or mixture that meets or exceeds the temperature range of your climate. This rating information can be found on most washer fluid containers.


WARNING!


Commercially available windshield washer solvents are flammable. They could ignite and burn you. Care must be exercised when filling or working around the washer solution.


Exhaust System The best protection against carbon monoxide entry into the vehicle body is a properly maintained engine exhaust system. If you notice a change in the sound of the exhaust system; or if the exhaust fumes can be detected inside the vehicle; or when the underside or rear of the vehicle is damaged; have an authorized technician inspect the complete ex- haust system and adjacent body areas for broken, dam- aged, deteriorated, or mispositioned parts. Open seams or loose connections could permit exhaust fumes to seep


MAINTAINING YOUR VEHICLE 371
into the passenger compartment. In addition, inspect the exhaust system each time the vehicle is raised for lubri- cation or oil change. Replace as required.


WARNING!


Exhaust gases can injure or kill. They contain carbon monoxide (CO), which is colorless and odorless. Breathing it can make you unconscious and can eventually poison you. To avoid breathing CO, refer to Exhaust Gas in the Safety Tips section of this manual.


372 MAINTAINING YOUR VEHICLE


CAUTION!


CAUTION!


The catalytic converter requires the use of unleaded fuel only. Leaded gasoline will destroy the effective- ness of the catalyst as an emissions control device and may seriously reduce engine performance and cause serious damage to the engine.


Under normal operating conditions, the catalytic con- verter will not require maintenance. However, it is im- portant to keep the engine properly tuned to assure proper catalyst operation and prevent possible catalyst damage.


Damage to the catalytic converter can result if your vehicle is not kept in proper operating condition. In the event of engine malfunction, particularly involv- ing engine misfire or other apparent loss of perfor- mance, have your vehicle serviced promptly. Contin- ued operation of your vehicle with a severe malfunction could cause the converter to overheat, resulting in possible damage to the converter and vehicle.


NOTE: systems can result against you.


Intentional tampering with emissions control in civil penalties being assessed


WARNING!


A hot exhaust system can start a fire if you park over materials that can burn. Such materials might be grass or leaves coming into contact with your exhaust system. Do not park or operate your vehicle in areas where your exhaust system can contact anything that can burn.


In unusual situations involving grossly malfunctioning engine operation, a scorching odor may suggest severe and abnormal catalyst overheating. If this occurs, stop the vehicle, turn off the engine and allow it to cool. Service, including a tuneup to manufacturer’s specifica- tions, should be obtained immediately.


MAINTAINING YOUR VEHICLE 373
To minimize the possibility of catalytic converter dam- age: • Do not shut off the engine or interrupt the ignition, when the transmission is in gear and the vehicle is in motion. • Do not try to start the engine by pushing or towing the • Do not idle the engine with any spark plug wires disconnected or removed, such as when diagnostic testing, or for prolonged periods during very rough idle or malfunctioning operating conditions.


vehicle.


374 MAINTAINING YOUR VEHICLE Cooling System


WARNING!


You or others can be badly burned by hot engine coolant (antifreeze) or steam from your radiator. If you see or hear steam coming from under the hood, do not open the hood until the radiator has had time to cool. Never try to open a cooling system pressure cap when the radiator or coolant bottle is hot.


Engine Coolant Checks Check the engine coolant (antifreeze) protection every 12 months (before the onset of freezing weather, where applicable). If the engine coolant (antifreeze) is dirty or rusty in appearance, the system should be drained, flushed and refilled with fresh antifreeze/coolant. Check the front of the A/C condenser for any accumulation of


bugs, leaves, etc. If dirty, clean by gently spraying water from a garden hose vertically down the face of the condenser. Check the engine cooling system hoses for brittle rubber, cracking, tears, cuts, and tightness of the connection at the coolant recovery bottle and radiator. Inspect the entire system for leaks. With the engine at normal operating temperature (but not running), check the cooling system pressure cap for proper vacuum sealing by draining a small amount of engine coolant (antifreeze) from the radiator drain cock. If the cap is sealing properly, the engine coolant (anti- freeze) will begin to drain from the coolant recovery bottle. DO NOT REMOVE THE COOLANT PRESSURE CAP WHEN THE COOLING SYSTEM IS HOT.


Cooling System — Drain, Flush, and Refill If the engine coolant (antifreeze) is dirty and contains a considerable amount of sediment, clean and flush with
