TECHNICAL SPECIFICATIONS

VEHICLE IDENTIFICATION NUMBER
The Vehicle Identification Number (VIN) is found on the left front corner of the A-pillar, visible from the outside of the vehicle through the windshield.
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 high-quality six-sided (hex) deep wall socket.

FUEL REQUIREMENTS
2.0L ENGINE
This engine is designed to meet all emission 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 other heavier load conditions, such as while towing. 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 your dealer immediately. Use of gasoline with a lower than recommended octane number can cause engine failure and may void or not be covered by 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.

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.
While operating on gasoline with an octane number of 87, 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 your dealer immediately. Use of gasoline with an octane number lower than 87 can cause engine failure and may void or not be covered by 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.

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 have 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 clearly 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 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
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.

Phone Operation

OPERATION
Voice commands can be used to operate the Uconnect Phone and to navigate through the Uconnect Phone menu structure. Voice commands are required after most Uconnect Phone prompts. There are two general methods for how Voice Command works:

1. Say compound commands like “Call John Smith mobile”.
2. Say the individual commands and allow the system to guide you to complete the task. You will be prompted for a specific command and then guided through the available options.

• Prior to giving a voice command, one must wait for the beep, which follows the “Listen” prompt or another prompt.
• For certain operations, compound commands can be used. For example, instead of saying “Call” and then “John Smith” and then “mobile”, the following compound command can be said: “Call John Smith mobile.”
• For each feature explanation in this section, only the compound command form of the voice command is given. You can also break the commands into parts and say each part of the command when you are asked for it. For example, you can use the compound command form voice command “Search for John Smith,” or you can break the compound command form into two voice commands: “Search Contact” and when asked “John Smith.” Please remember, the Uconnect Phone works best when you talk in a normal conversational tone as if speaking to someone sitting a few feet/meters away from you.

NATURAL SPEECH
Your Uconnect Phone Voice system uses a Natural Language Voice Recognition (VR) engine. Natural speech allows the user to speak commands in phrases or complete sentences. The system filters out certain non-word utterances and sounds such as “ah” and “eh.” The system handles fill-in words such as “I would like to.” The system handles multiple inputs in the same phrase or sentence such as “make a phone call” and “to Kelly Smith”. For multiple inputs in the same phrase or sentence, the system identifies the topic or context and provides the associated follow-up prompt such as “Who do you want to call?” in the case where a phone call was requested but the specific name was not recognized.
The system utilizes continuous dialog; when the system requires more information from the user it will ask a question to which the user can respond without pushing the Voice Command button on the steering wheel.

HELP COMMAND
If you need assistance at any prompt, or if you want to know your options at any prompt, say “Help” following the beep.
To activate the Uconnect Phone from idle, simply push the Phone button (if active) on your steering wheel and say a command or say “help.” All Uconnect Phone sessions begin with a push of the VR button or the Phone button (if active) on the radio control head.

CANCEL COMMAND
At any prompt, after the beep, you can say “Cancel” and you will be returned to the main menu.
You can also push the VR button or Phone button (if active) on your steering wheel when the system is listening for a command and be returned to the main or previous menu.
