gasoline is not recommended. Under normal conditions, the use of premium gasoline will not provide a benefit over high quality regular gasolines, and in some circum- stances may result in poorer performance.
306 STARTING AND OPERATING
5.7L Engines (If Equipped)
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. Under normal conditions, the use of premium gasoline will not provide a benefit over high quality regular and mid-grade gasolines, and in some circumstances may result in poorer performance. 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 manufacturer’s world wide 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 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. 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.
STARTING AND OPERATING 307
Problems that result from using methanol/gasoline or E85 Ethanol blends are not the responsibility of the 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 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 whether or not his/her gasoline contains MMT.
308 STARTING AND OPERATING
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 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, 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 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.
NOTE: systems can result against you.
Intentional tampering with emissions control in civil penalties being assessed
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 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
STARTING AND OPERATING 309
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.
FLEXIBLE FUEL (4.7L ONLY) — IF EQUIPPED
E-85 General Information The information in this section is for Flexible Fuel vehicles only. These vehicles can be identified by the unique fuel filler door label that states Ethanol (E-85) or Unleaded Gasoline Only. This section only covers those subjects that are unique to these vehicles. Please refer to the other sections of this manual for information on features that are common between Flexible Fuel and gasoline only powered vehicles.
310 STARTING AND OPERATING
CAUTION!
Only vehicles with the E-85 fuel filler door label can operate on E-85.
ETHANOL FUEL (E-85) E-85 is a mixture of approximately 85% fuel ethanol and 15% unleaded gasoline.
WARNING!
Ethanol vapors are extremely flammable and could cause serious personal injury. Never have any smok- ing materials lit in or near the vehicle when remov- ing the fuel filler tube cap (gas cap) or filling the tank. Do not use E-85 as a cleaning agent and never use it near an open flame.
Fuel Requirements Your vehicle will operate on both unleaded gasoline with an octane rating of 87, or E-85 fuel, or any mixture of these two. For best results, a refueling pattern that alternates be- tween E-85 and unleaded gasoline should be avoided. When you do switch fuels, it is recommended that • you do not switch when the fuel gauge indicates less • you do not add less than 5 gallons when refueling • you operate the vehicle immediately after refueling for
than 1/4 full
a period of at least 5 minutes
Observing these precautions will avoid possible hard starting and/or significant deterioration in drivability during warm up.
NOTE: When the ambient temperature is above 90°F (32°C), you may experience hard starting and rough idle following start up even if the above recommendations are followed. Selection Of Engine Oil For Flexible Fuel Vehicles (E-85) and Gasoline Vehicles Whether operating the vehicle on an E-85 ethanol fuel or unleaded gasoline the engine oil requirements are the same. Refer to “Maintenance Procedures” in Section 7 of this manual for the proper quality and viscosity engine oil. Starting The characteristics of E-85 fuel make it unsuitable for use when ambient temperatures fall below 0°F (-18°C). In the range of 0°F (-18°C) to 32°F (0°C), you may experience an increase in the time it takes for your engine to start, and a deterioration in drivability (sags and/or hesitations) until the engine is fully warmed up.
STARTING AND OPERATING 311
Cruising Range Because E-85 fuel contains less energy per gallon than gasoline, you will experience an increase in fuel con- sumption. You can expect your miles per gallon (mpg) and your driving range to decrease by about 30% com- pared to gasoline operation. Replacement Parts Many components in your Flexible Fuel Vehicle (FFV) are designed to be compatible with ethanol. Always be sure that your vehicle is serviced with correct ethanol com- patible parts.
CAUTION!
Replacing fuel system components with non-ethanol compatible components can damage your vehicle.
312 STARTING AND OPERATING
Maintenance If you operate the vehicle using E-85 fuel, follow “Main- tenance Schedule B.” Refer to Section 8 of this manual.
CAUTION!
Do not use ethanol mixture greater than 85% in your vehicle. It will cause difficulty in cold starting and may affect driveability.
FUEL REQUIREMENTS — DIESEL Diesel fuels are available from most reputable fuel mar- keters. We encourage you to use only the best quality fuel with a calculated Cetane Index of 50 or higher. In addition, the manufacturer recommends using diesel fuel with a sulfur content of less than 15 ppm. See your authorized dealer or distributor for further information regarding fuels available in your area.
In areas where diesel fuel is below the recommended quality levels (high levels of sulfur and water) it is critical to monitor the fuel filter for contamination and the “Water-In-Fuel” message in the EVIC (Refer to Section 4). Failure to properly service the fuel system for these items can significantly reduce engine life and lead to major engine repair. More frequent service intervals of the fuel filter/water separator unit may be required under these conditions than those shown in “Maintenance Schedule A or B.” See your authorized dealer or distributor for specific information.
ADDING FUEL
CAUTION!
DO NOT put gasoline in your diesel vehicle (if equipped). If you accidentally put gasoline in your vehicle, DO NOT start the engine. This will cause damage to the fuel system. Have the fuel system flushed.
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.

314 STARTING AND OPERATING
CAUTION!
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 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.
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.
STARTING AND OPERATING 315
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.

• 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 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 Vehicle Identification Number (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. 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 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 vehi- cle’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. Inflation Pressure This is the cold tire inflation pressure for your vehicle for all loading conditions up to full GAWR.
STARTING AND OPERATING 317
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 insure that the GVWR has not been exceeded. 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
318 STARTING AND OPERATING
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 effect 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. 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. 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 include 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.
STARTING AND OPERATING 319
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
320 STARTING AND OPERATING
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 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.
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.

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. The addition of pas- sengers and cargo may require reducing tongue load and
Gross Trailer Weight (GTW). Redistributing cargo (to the trailer) may be necessary to avoid exceeding Rear Gross Axle Weight Rating (GAWR) of 3,200 lbs (1 451 kg). Refer to “Weight Distributing Hitch” in this section. 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. Never exceed the maximum tongue weight stamped on your trailer hitch.

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.
326 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 drivetrain components the following guidelines are recommended:
CAUTION!
• Avoid towing a trailer for the first 500 miles (805 km) of vehicle operation. Doing so may damage your vehicle. • During the first 500 miles (805 km) of trailer towing,
limit your speed to 50 mph (80 km/h).
Perform the maintenance listed in Section 8 of this manual. When towing a trailer, never exceed the GAWR, or GCWR, ratings.
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 automatic transmission in P (Park). For four-wheel-drive vehicles, make sure the transfer case is not in neutral. Always, block or ⬙chock⬙ the trailer wheels.
STARTING AND OPERATING 327
• GCWR must not be exceeded. • 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. 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).
328 STARTING AND OPERATING
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 the Tires–General Information section of this manual on Tire Pressures for proper tire inflation procedures.
− Also, check the trailer tires for proper tire inflation
pressures before trailer usage.
− Check for signs of tire wear or visible tire damage before towing a trailer. Refer to the Tires–General Information section of this manual on Tread Wear Indicators for the proper inspection procedure.
− When replacing tires, refer to the Tires–General Infor- mation section of this manual on Replacement Tires for
proper tire replacement procedures. 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).
STARTING AND OPERATING 329
Towing Requirements — Trailer Lights & Wiring Whenever you pull a trailer, regardless of the trailer size, stop lights and turn signals on the trailer are required for motoring safety. The Trailer Tow Package may include a 4 and 7 pin wiring harness. 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.
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 ef- fort, and longer stopping distances.
WARNING!
Do not connect trailer brakes to your vehicle’s hydrau- lic 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 additional space between your vehicle and the vehicle in front of you. Failure to do so could result in an accident.

Towing Tips Before setting out on a trip, practice turning, stopping and backing the trailer in an area away from heavy traffic.
Towing Tips — Automatic Transmission The “D” range can be selected when towing. However, 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 build up. This action will also provide better engine braking. The automatic transmission fluid and filter should be changed if you REGULARLY tow a trailer for more than 45 minutes of continuous operation. Refer to “Mainte- nance Schedule B” in Section 8 of this manual for transmission fluid change intervals. NOTE: Check the automatic transmission fluid level before towing.
STARTING AND OPERATING 331
Towing Tips — Electronic Speed Control (If Equipped) − Don’t 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.
Towing Tips — Cooling System To reduce potential for engine and transmission over- heating, take the following actions: − City Driving When stopped for short periods of time, put transmission in neutral and increase engine idle speed. − Highway Driving Reduce speed.

Shifting Out Of Neutral (N) Use the following procedure to prepare your vehicle for normal usage. 1. Depress brake pedal. 2. Turn the ignition key ON, engine off. 3. Shift transmission into N (Neutral). 4. Shift transfer case out of N (Neutral).
Hold down N (Neutral) “pin” switch (with a pen, etc.) for 4 seconds until the LED lamp by the switch starts to blink indicating shift in progress. Lamp will stop blinking (go out) when shift is complete. The “4WD SYSTEM IN NEUTRAL” message will no longer be displayed on the EVIC (Electronic Vehicle Information Center). Refer to “Electronic Vehicle Information Center (EVIC)” in Sec- tion 4 of this manual. (See page 183 for more informa- tion.)
STARTING AND OPERATING 335
Neutral Switch 5. Shift transmission into P (Park). 6. Start the engine. 7. Shift transmission into D (Drive).
336 STARTING AND OPERATING
NOTE: When shifting out of transfer case N (Neutral), turning the engine OFF may be required to avoid gear clash.
WARNING!
You or others could be injured if you leave the vehicle unattended with the transfer case in the N (Neutral) position without first fully engaging the parking brake. The transfer case N (Neutral) position disengages both the front and rear driveshafts from the powertrain and will allow the vehicle to move regardless of the transmission position. The parking brake should always be applied when the driver is not in the vehicle.
CAUTION!
Do not use a bumper mounted clamp-on tow bar on your vehicle. The bumper face bar will be damaged.
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 after- market equipment to the front of your vehicle. This could adversely affect the functioning of the airbag system and you could be injured.

338 WHAT TO DO IN EMERGENCIES
HAZARD WARNING FLASHERS Your vehicle’s hazard warning flasher is an emergency warning system. When you activate it, all front and rear directional signals will flash intermittently. Use it when your vehicle is disabled on or near the road. It warns other drivers to steer clear of you and your vehicle. This is an emergency warning system, not to be used when the vehicle is in motion.
Hazard Warning Switch
To activate the warning flasher, push down on the button on top of the steering column until it latches. To turn the warning flasher off, push down again to unlatch the button. NOTE: With extended use, the 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 transmission in N
(Neutral), but do not increase engine idle speed.
NOTE: There are steps that you can take to slow down an impending overheat condition. If your air conditioner is on, turn it off. The air conditioning system adds heat to the engine cooling system and turning off the A/C
removes this heat. You can also turn the Temperature Control to maximum heat, the Mode Control to floor, and the Fan 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.
CAUTION!
Driving with a hot cooling system could damage your vehicle. If the temperature gauge reads “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 the “H”, and you hear continuous chimes, turn the engine off immediately, and call for service.

JACKING AND TIRE CHANGING
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 designed to use as 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.
340 WHAT TO DO IN EMERGENCIES
Jack Location The scissor-type jack and tire changing tools are located in the passenger side compartment behind the second row seat.
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 341
Spare Tire Removal Fit the jack handle extension over the drive nut. Use the Lug Wrench to rotate the nut counter clockwise until the spare is on the ground with enough slack in the cable to allow to pull the tire out from under the vehicle.
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 damage 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.
Lowering/Raising Spare Tire
342 WHAT TO DO IN EMERGENCIES
Preparations For Jacking Park the vehicle on a firm level surface, avoid ice or slippery areas, set the parking brake and place the gear selector in P (Park). Turn OFF the ignition.
For example, if changing the right front tire, block the left rear wheel. • Passengers should not remain in the vehicle when the
vehicle is being jacked.
WARNING!
Jacking Instructions
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. • Turn on the Hazard Warning Flasher.
• Block both the front and rear of the wheel diagonally oppo- site of the jacking position.
1. Remove the spare tire, jack, and tools from storage. 2. Loosen (but do not remove) the wheel lug nuts by turning them to the left one turn while the wheel is still on the ground. 3. Assemble the jack and jacking tools as shown. Connect jack handle driver (A) to two extensions (B), then to the lug wrench (C).
WHAT TO DO IN EMERGENCIES 343
4. Locate the jack as shown. For the front axle, place it under the front lower control arm as shown. For the rear axle, place it under the axle near the wheel to be changed. Ensure the jack is closest to the inside of the wheel when jacking on the rear axle. Do not raise the vehicle until you are sure the jack is fully engaged.
Front 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.
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. 9. Finish tightening the lug nuts. Push down on the wrench while tightening for increased leverage. Alternate
WHAT TO DO IN EMERGENCIES 345
nuts until each nut has been tightened twice. Correct wheel nut tightness is 130 N·m (95 ft. lbs). 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.
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!
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.
WARNING!
Do not use power tools to winch the tire up or down. Impact type tools may damage the winch mecha- nism.
11. Secure the tire, jack, and tools in their proper loca- tions.
12. Reinstall the plastic plug into the floor of the cargo area.
346 WHAT TO DO IN EMERGENCIES
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!
Battery fluid is a corrosive acid solution; do not allow battery fluid to contact eyes, skin or clothing. Don’t lean over battery when attaching clamps or allow the clamps to touch each other. If acid splashes in eyes or on skin, flush contaminated area immedi- ately with large quantities of water. A battery generates hydrogen gas which is flam- mable and explosive. Keep flame or spark away from the vent holes. 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 P (Park), and turn the ignition OFF. 3. Turn off the heater, radio, and all unnecessary electri- cal 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.

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.” 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 dealer for service as soon as possible.
CAUTION!
• Prolonged driving with the “Malfunction Indica- tor Light” on could cause further damage to the emission control system. It could also affect fuel economy and driveability. The vehicle must be serviced before any emissions tests can be per- formed. • If the “Malfunction Indicator Light” is flashing while the engine is running, severe catalytic con- verter 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. This message may be temporarily overridden by pressing either the C/T, STEP, or MENU buttons. However, after one minute of no customer interaction, the EVIC will display again the “CHECK GASCAP” message. The message will remain displayed until the vehicle diagnos- tic 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
MAINTAINING YOUR VEHICLE 359
cap. If the problem is detected twice in a row, the system will turn on the Malfunction Indicator Light (MIL). Resolving the problem will turn the MIL light 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 which have an I/M (Inspection and Maintenance) requirement, this check verifies the following: the MIL (Malfunction Indicator Lamp) is functioning and is not on when the engine is running, and that the OBD (On Board Diagnostic) system is ready for testing. Normally, the OBD system will be ready. The OBD system may not be ready if your vehicle was recently serviced, if you recently had a dead battery, or a battery
360 MAINTAINING YOUR VEHICLE
replacement. If the OBD 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 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 your 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 key or start the engine. This means that your vehicle’s OBD system is not ready and you should not proceed to the I/M station. b. The MIL will not flash at all and will remain fully illuminated until you turn off the ignition key or start the engine. This means that your vehicle’s OBD system is ready and you can proceed to the I/M station.
If your OBD 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 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 system is ready or not ready, if the MIL symbol is illuminated

WARNING!
You can be badly injured working on or around a motor vehicle. Do only that 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 mechanic.
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 symbol is on with the engine running.
REPLACEMENT PARTS Use of genuine Mopar威 parts for normal/scheduled maintenance and repairs is highly recommended to in- 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 dealer has the qualified service personnel, 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.
362 MAINTAINING YOUR VEHICLE
MAINTENANCE PROCEDURES The pages that follow contain the required maintenance services determined by the engineers who designed your vehicle. Besides the maintenance items for which there are fixed maintenance intervals, there are other items that should operate satisfactorily without periodic maintenance. However, if a malfunction of these items does occur, it could adversely affect the engine or vehicle performance. These items should be inspected if a malfunction is observed or suspected. 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 5 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.
CAUTION!
Overfilling or underfilling the crankcase will cause aeration or loss of oil pressure. This could damage your engine.
Change Engine Oil Road conditions as well as your kind of driving affect the interval at which your oil should be changed. Check the following to determine if any apply to you: • Day or night temperatures are below 32°F (0°C) • Stop and go driving • Extensive engine idling • Driving in dusty conditions • Short trips of less than 10 miles (16.2 km) • More than 50% of your driving is at sustained high • Trailer towing • Taxi, Police, or delivery service (Commercial Service) • Off road or desert operation
speeds during hot weather, above 90°F (32°C)
• If equipped for and operating with E-85 (ethanol)
MAINTAINING YOUR VEHICLE 363
fuel.
If ANY of these apply to you, then change your engine oil every 3,000 miles (5 000 km) or 3 months, whichever comes first, and follow the maintenance recommenda- tions in “Maintenance Schedule B.” If none of these apply to you, then change your engine oil every 6,000 miles (10 000 km) or 6 months, whichever comes first. NOTE: Under no circumstances should oil change in- tervals exceed 6,000 miles (10 000 km) or 6 months whichever comes first.

indiscriminately discarded, can present a problem to the 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 efficient service. Mopar威 engine oil filters are high quality oil filters and are recommended.
Drive Belts — Check Condition and Tension Belt tension is controlled by means of an automatic tensioner. No belt tension adjustments are required. However, belt and belt tensioner condition should be inspected at the specified intervals, and replaced if re- quired. See your authorized dealer for service. At the mileage indicated in the maintenance schedule, all belts and tensioner should be checked for condition. Improper belt tension can cause belt slippage and failure. Belts should be inspected for evidence of cuts, cracks, glazing, or frayed cords and replaced if there is indication of damage which could result in belt failure. Low gen- erator belt tension can cause battery failure. Also, check belt routing to make sure there is no inter- ference between the belts and other engine components.
Spark Plugs Spark plugs must fire properly to assure engine perfor- mance and emission control. New spark plugs should be installed at the specified mileage. The entire set should be replaced if there is any malfunction due to a faulty spark plug. Refer to the “Vehicle Emission Control Informa- tion” label in the engine compartment for spark plug information. Spark Plug Wires The spark plug wires should be kept clean and properly connected. Terminals should be fully seated. Cracked, damaged, or faulty wires should be replaced. Engine Air Cleaner Filter Under normal driving conditions, replace the air filter at the intervals shown on “Maintenance Schedule A.” If, however, you drive the vehicle frequently under dusty or

severe conditions, the filter element should be inspected periodically and replaced if necessary at the intervals shown on “Maintenance Schedule B.”
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.

Catalytic Converter The catalytic converter requires the use of unleaded fuel only. Leaded gasoline will destroy the effectiveness of the converter as an emission control device. 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.
CAUTION!
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.

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 ex- haust system. Do not park or operate your vehicle in areas where your exhaust system can contact any- thing 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 tune up to manufacturer’s specifica- tions, should be obtained immediately. To minimize the possibility of catalytic converter dam- age:

MAINTAINING YOUR VEHICLE 373
WARNING!
Do not use Automatic Transmission Fluid (ATF) or other types of power steering fluids when servicing the power steering system of this vehicle. Damage to the power steering system can result from the use of the wrong power steering fluid.
Fluid level should be checked on a level surface with the engine off to prevent injury from moving parts, and to insure accurate fluid level reading. Do not overfill. Use only the manufacturer’s recommended fluid.
Checking the power steering fluid level at a defined service interval is not required. The fluid should only be checked if a leak is suspected, abnormal noises are apparent, and/or the system is not functioning as antici- pated. Coordinate inspection efforts through a certified “DaimlerChrysler Dealership.”
If necessary, add fluid to restore to the proper indicated level. With a clean cloth, wipe any spilled fluid from all surfaces. Refer to Fluids, Lubricants, and Genuine Parts for correct fluid type. NOTE: Upon initial start-up in cold weather, the power steering pump may make noise for a short period 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.
374 MAINTAINING YOUR VEHICLE
Body Lubrication Locks and all body pivot points, including such items as seat tracks, doors, tailgate and hood hinges, should be lubricated periodically to assure quiet, easy operation and to protect against rust and wear. Prior to the appli- cation 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 compo- nents 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 directly into the lock cylinder.
Windshield Wiper Blades The rubber edges of the wiper blades and the windshield should be cleaned periodically with a sponge or soft cloth and a mild nonabrasive cleaner to remove accumulations of salt or road film. 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. Windshield Washers — Front and Rear On vehicles equipped with a Vehicle Information Center, 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. It is located in the front of the engine compartment (on the driver side), and should be checked for fluid level at regular intervals. Fill the reservoir with windshield washer (not antifreeze/coolant) and operate the system for a few seconds to flush out the residual water.

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 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.
376 MAINTAINING YOUR VEHICLE
WARNING!
Cooling System
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.
WARNING!
You or others can be badly burned by hot antifreeze/ coolant or steam from your radiator. If you see or hear steam coming from under the hood, don’t 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 antifreeze/coolant protection every 12 months (before the onset of freezing weather, where applicable). If antifreeze/coolant 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 coolant from the radiator drain cock. If the cap is sealing properly, the antifreeze/coolant will begin to drain from the coolant recovery bottle. DO NOT REMOVE THE COOLANT PRESSURE CAP WHEN THE COOLING SYSTEM IS HOT.
MAINTAINING YOUR VEHICLE 377
Cooling System — Drain, Flush, And Refill At the intervals shown in the appropriate “Maintenance Schedule,” the system should be drained, flushed, and refilled. If the solution is dirty and contains a considerable amount of sediment, clean and flush with reliable cooling system cleaner. Follow with a thorough rinsing to remove all deposits and chemicals. Properly dispose of old antifreeze/coolant solution. Selection Of Coolant Use only the manufacturer’s recommended antifreeze/ coolant, refer to Fluids, Lubricants, and Genuine Parts for correct antifreeze/coolant type.
378 MAINTAINING YOUR VEHICLE
CAUTION!
Mixing of antifreeze/coolant other than the specified HOAT antifreeze/coolant may result in decreased corrosion protection and engine damage. If a non- HOAT antifreeze/coolant is introduced into the cool- ing system in an emergency, it should be replaced with the specified antifreeze/coolant as soon as pos- sible. Do not use plain water alone or alcohol base antifreeze/coolant products. Do not use additional rust inhibitors or antirust products, as they may not be compatible with the antifreeze/coolant and may plug the radiator. This vehicle has not been designed for use with Propylene Glycol based antifreeze/coolant. Use of Propylene Glycol base antifreeze/coolant is not rec- ommended.
Adding Coolant
Your vehicle has been built with an improved antifreeze/
coolant that allows extended maintenance intervals. This
antifreeze/coolant can be used up to 5 Years or 100,000
miles before replacement. To prevent reducing this ex-
tended maintenance period, it is important that you use
the same antifreeze/coolant throughout the life of your
vehicle. Please review these recommendations for using
Hybrid Organic Additive
(HOAT)
antifreeze/coolant.
When adding antifreeze/coolant, a minimum solution of
50% recommended Mopar威 Antifreeze/ Coolant 5 Year/
100,000 Mile Formula HOAT (Hybrid Organic Additive
Technology), or equivalent, in water should be used. Use
higher concentrations (not to exceed 70%) if temperatures
below -34°F (-37°C) are anticipated.
Technology
Use only high purity water such as distilled or deionized water when mixing the water/antifreeze (coolant) solu- tion. The use of lower quality water will reduce the amount of corrosion protection in the engine cooling system. Please note that it is the owner’s responsibility to main- tain the proper level of protection against freezing ac- cording to the temperatures occurring in the area where the vehicle is operated. NOTE: Mixing antifreeze/coolant types will decrease the life of the antifreeze/coolant and will require more frequent antifreeze/coolant changes. Cooling System Pressure Cap The cap must be fully tightened to prevent loss of antifreeze/coolant, and to insure that antifreeze/coolant will return to the radiator from the coolant recovery tank.
MAINTAINING YOUR VEHICLE 379
The cap should be inspected and cleaned if there is any accumulation of foreign material on the sealing surfaces.
WARNING!
• The warning words DO NOT OPEN HOT on the cooling system pressure cap are a safety precau- tion. Never add antifreeze/coolant when the en- gine is overheated. Do not loosen or remove the cap to cool an overheated engine. Heat causes pressure to build up in the cooling system. To prevent scalding or injury, do not remove the pressure cap while the system is hot or under pressure. • Do not use a pressure cap other than the one
