VEHICLE IDENTIFICATION NUMBER (VIN)

The VIN is found on the left front corner of the A-pillar, visible from the outside of the vehicle through the windshield.

Vehicle Identification Number

NOTE:
It is illegal to remove or alter the VIN plate.

BRAKE SYSTEM

Your vehicle is equipped with dual hydraulic brake systems. If either of the two hydraulic systems loses normal capability, the remaining system will still function. However, there will be some loss of overall braking effectiveness. You may notice increased pedal travel during application, greater pedal force required to slow or stop, and potential activation of the Brake Warning Light.
In the event power assist is lost for any reason (i.e., repeated brake applications with the engine off) the brakes will still function. However, the effort required to brake the vehicle will be much greater than that required with the power system operating.

WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure that the wheel is properly mounted to the vehicle. Any time a wheel has been removed and reinstalled on the vehicle, the lug nuts/bolts should be torqued using a properly calibrated torque wrench using a six-sided (hex) deep wall socket.

TORQUE SPECIFICATIONS

Lug Nut/Bolt Torque	Lug Nut/Bolt Size	Lug Nut/Bolt Socket Size
130 ft-lb (176 N·m)	M14 x 1.50	22 mm

Use only authorized dealer-recommended lug nuts/bolts and clean or remove any dirt or oil before tightening.
Inspect the wheel mounting surface before mounting the tire and remove any corrosion or lose particles.

Spare Tire Torque Specifications

Lug Nut/Bolt Torque	Lug Nut/Bolt Size	Lug Nut/Bolt Socket Size
59 ft-lb (80 N·m)	M14 x 1.50	22 mm

Use only authorized dealer-recommended lug nuts/bolts and clean or remove any dirt or oil before tightening.
Spare tire torque is for the spare tire carrier located on the swing gate.

Wheel Mounting Surface
Tighten the lug nuts/bolts in a star pattern until each nut/bolt has been tightened twice. Ensure that the socket is fully engaged on the lug nut/bolt (do not insert it halfway).

Torque Patterns
After 25 miles (40 km), check the lug nut/bolt torque to be sure that all the lug nuts/bolts are properly seated against the wheel.

WARNING!
To avoid the risk of forcing the vehicle off the jack, do not tighten the lug nuts/bolts fully until the vehicle has been lowered. Failure to follow this warning may result in personal injury.

FUEL REQUIREMENTS — GASOLINE ENGINE
While operating on gasoline with the required octane number, hearing a light knocking sound from the engine is not a cause for concern. However, if the engine is heard making a heavy knocking sound, see a dealer immediately. Use of gasoline with an octane number lower than recommended can cause engine failure and may void the New Vehicle Limited Warranty. Poor quality gasoline can cause problems such as hard starting, stalling, and hesitations. If you experience these symptoms, try another brand of gasoline before considering service for the vehicle.

2.0L ENGINE
This engine is designed to meet all emissions requirements and provide satisfactory fuel economy and performance when using high-quality unleaded regular gasoline having an octane rating of 87, as specified by the (R+M)/
2 method. The use of 91 or higher octane premium gasoline will allow these engines to operate to optimal performance. This increase in performance is most noticeable in hot weather or under heavy load conditions such as while towing.

3.6L ENGINE
This engine is designed to meet all emissions regulations and provide satisfactory fuel economy and performance when using high-quality unleaded regular gasoline having an octane rating of 87 as specified by the (R+M)/
2 method. The use of higher octane premium gasoline will not provide any benefit over regular gasoline in these engines.

REFORMULATED GASOLINE
Many areas of the country require the use of cleaner burning gasoline referred to as “reformulated gasoline”. Reformulated gasoline contains oxygenates and is specifically blended to reduce vehicle emissions and improve air quality. The use of reformulated gasoline is recommended. Properly blended reformulated gasoline will provide improved performance and durability of engine and fuel system components.

MATERIALS ADDED TO FUEL
Besides using unleaded gasoline with the proper octane rating, gasoline that contains detergents, corrosion, and stability additives is recommended. Using gasoline that has these additives will help improve fuel economy, reduce emissions, and maintain vehicle performance.
Designated TOP TIER Detergent Gasoline contains a higher level of detergents to further aid in minimizing engine and fuel system deposits. When available, the usage of TOP TIER Detergent gasoline is recommended. Visit
www.toptiergas.com for a list of TOP TIER Detergent Gasoline retailers.
Indiscriminate use of fuel system cleaning agents should be avoided. Many of these materials intended for gum and varnish removal may contain active solvents or similar ingredients. These can harm fuel system gasket and diaphragm materials.

GASOLINE/OXYGENATE BLENDS
Some fuel suppliers blend unleaded gasoline with oxygenates such as ethanol.

CAUTION!
DO NOT use E-85, gasoline containing methanol, or gasoline containing more than 15% ethanol (E-15). Use of these blends may result in starting and drivability problems, damage critical fuel system components, cause emissions to exceed the applicable standard, and/or cause the Malfunction Indicator Light to illuminate. Please observe pump labels as they should communicate if a fuel contains greater than 15% ethanol (E-15).

Problems that result from using gasoline containing more than 15% ethanol (E-15) or gasoline containing methanol are not the responsibility of the manufacturer and may void or not be covered under the New Vehicle Limited Warranty.

DO NOT USE E-85 IN NON-FLEX FUEL VEHICLES
Non-Flex Fuel Vehicles (FFV) are compatible with gasoline containing up to 15% ethanol (E-15). Use of gasoline with higher ethanol content may void the New Vehicle Limited 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
• OBD II Malfunction Indicator Light on
• Poor engine performance
• Poor cold start and cold drivability
• Increased risk for fuel system component corrosion

CNG AND LP FUEL SYSTEM MODIFICATIONS
Modifications that allow the engine to run on Compressed Natural Gas (CNG) or Liquid Propane (LP) may result in damage to the engine, emissions, and fuel system components. Problems that result from running CNG or LP are not the responsibility of the manufacturer and may void or not be covered under the New Vehicle Limited Warranty.

MMT IN GASOLINE
Methylcyclopentadienyl Manganese Tricarbonyl (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 emissions 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 the gasoline contains MMT. MMT is prohibited in Federal and California reformulated gasoline.

FUEL SYSTEM CAUTIONS

CAUTION!
Follow these guidelines to maintain your vehicle’s performance:

• The use of leaded gasoline is prohibited by Federal law. Using leaded gasoline can impair engine performance and damage the emissions 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 an authorized 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 are not the responsibility of the manufacturer and may void or not be covered under the New Vehicle Limited Warranty.

NOTE:
Intentional tampering with the emissions control system can result in civil penalties being assessed against you.
