Starting and Stopping the Engine

STARTING AND STOPPING THE ENGINE – PRECAUTIONS
Extended idling at high engine speeds can produce very high temperatures in the engine and exhaust system, creating the risk of fire or other damage. Do not park, idle or drive your vehicle on dry grass or other dry ground cover. The emission system heats up the engine compartment and exhaust system, creating the risk of fire. Do not start the engine in a closed garage or in other enclosed areas. Exhaust fumes are toxic. Always open the garage door before you start the engine. Failure to follow this instruction could result in personal injury or death. Do not use starting fluid, for example, ether, in the air intake system. Such fluid could cause immediate explosive damage to the engine and possible personal injury. Exhaust leaks may result in the entry of harmful and potentially lethal fumes into the passenger compartment. If you smell exhaust fumes inside your vehicle, have your vehicle inspected immediately. Do not drive if you smell exhaust fumes. The powertrain control system meets all Canadian interference-causing equipment standard requirements regulating the impulse electrical field or radio noise.

If you stop your vehicle and leave the engine idling for long periods, we recommend that you do one of the following:

• Open the windows at least 1 in (2.5 cm).
• Set your climate control to outside air.

PUSH BUTTON IGNITION SWITCH

Switching the Ignition Off
When the ignition is on or in accessory mode, press the push button ignition switch once without your foot on the brake pedal.

Switching the Ignition to Accessory Mode
When the ignition is off, press the push button ignition switch once without your foot on the brake pedal. All electrical circuits and accessories are operational and the warning lamps and indicators are illuminated.

Note: Your vehicle has a battery saver feature that shuts your vehicle off when it detects a certain amount of battery drain or after approximately 30 minutes of inactivity in accessory mode.

Starting the Engine
With the transmission in park (P), press the brake pedal and press the push button ignition switch. An indicator light on the button illuminates when the ignition is on and when the engine starts.

Note: The system may not function if the passive key is close to metal objects or electronic devices, for example, keys or a cell phone.
Note: A valid key must be inside your vehicle to switch the ignition on and start the engine.

STARTING THE ENGINE

Starting a Gasoline Engine
Before starting your vehicle, check the following:

• Make sure that the headlamps and electrical accessories are off.
• Make sure that the parking brake is on.
• Make sure that the transmission is in park (P).

1. Fully press the brake pedal.
   Note: Do not touch the accelerator pedal.
2. Press the push button ignition switch.

Note: The engine may continue cranking for up to 15 seconds or until it starts.
Note: The engine takes longer to start at lower temperatures. It may crank for several seconds when very cold.

Restarting the Engine After Stopping it
The system allows you to start the engine within 10 seconds of switching it off, even if it does not detect a valid passive key. Within 10 seconds of switching the engine off, fully press the brake pedal and press the push button ignition switch. After 10 seconds, you can no longer start the engine if the system does not detect a valid passive key. When you start the engine, it remains running until you press the push button ignition switch, even if your vehicle does not detect a valid passive key. If you open and close a door when the engine is running, the system searches for a valid passive key.

ENGINE BLOCK HEATER (If Equipped)
Failure to follow engine block heater instructions could result in property damage or serious personal injury. Do not use your heater with ungrounded electrical systems or two-pronged adapters. There is a risk of electrical shock. Do not fully close the hood, or allow it to drop under its own weight when using the engine block heater. This could damage the power cable and may cause an electrical short resulting in fire, injury, and property damage.

We recommend that you do the following for a safe and correct operation:

• Use a 16-gauge outdoor extension cord that is product-certified by the Underwriter’s Laboratory (UL) or Canadian Standards Association (CSA). This extension cord must be suitable for use outdoors, in cold temperatures, and be clearly marked Suitable for Use with Outdoor Appliances.
• Do not use an indoor extension cord outdoors. This could result in an electric shock or become a fire hazard.
• Use as short an extension cord as possible.
• Do not use multiple extension cords.
• Make sure that when in operation, the extension cord plug and engine block heater cord plug connections are free and clear of water. This could cause an electric shock or fire.
• If the engine block heater cord is under the hood, do not remove the wiring from its original location. Do not close the hood on the extension wiring.
• Park your vehicle in a clean area, clear of combustible materials.
• Firmly connect the engine block heater cord and the extension cord.
• Check the extension cord for heat anywhere when the system has been operating for approximately 30 minutes.
• Unplug and properly stow the system before starting and driving your vehicle. The protective cover seals the terminals of the engine block heater cord plug when not in use.
• Check the engine block heater system for proper operation before winter.

How Does the Engine Block Heater Work
The engine block heater warms the engine coolant. This allows the climate control system to quickly respond. The equipment includes a heater element installed in the engine block and a wire harness. You can connect the system to a grounded 220-240 volt AC electrical source.

Note: The engine block heater is most effective when outdoor temperatures are below 0°F (-18°C).

Using the Engine Block Heater
Make sure the receptacle terminals are clean and dry prior to use. Clean them with a dry cloth if necessary. The heater uses 0.4 to 1.0 kilowatt-hours of energy per hour of use. The system does not have a thermostat. It achieves maximum temperature after approximately three hours of operation. Using the engine block heater longer than three hours does not improve system performance and unnecessarily uses electricity.

STOPPING THE ENGINE
Stopping the Engine When Your Vehicle is Stationary

FUEL AND REFUELING PRECAUTIONS
Do not overfill the fuel tank. The pressure in an overfilled tank may cause leakage and lead to fuel spray and fire. The fuel system may be under pressure. If you hear a hissing sound near the fuel filler inlet, do not refuel until the sound stops. Otherwise, fuel may spray out, which could cause serious personal injury. Fuels can cause serious injury or death if misused or mishandled. Fuel may contain benzene, which is a cancer-causing agent. When refueling always shut the engine off and never allow sparks or open flames near the fuel tank filler valve. Never smoke or use a cell phone while refueling. Fuel vapor is extremely hazardous under certain conditions. Avoid inhaling excess fumes. Read and follow all the instructions on the pump island.

Follow these guidelines when refueling:

• Extinguish all smoking materials and any open flames before refueling your vehicle.
• Switch the engine off before refueling.
• Automotive fuels can be harmful or fatal if swallowed. Fuel is highly toxic and if swallowed can cause death or permanent injury. If fuel is swallowed immediately call a physician, even if no symptoms are immediately apparent. The toxic effects of fuel may not be apparent for hours.
• Avoid inhaling fuel vapors. Inhaling fuel vapor can lead to eye and respiratory tract irritation. In severe cases, excessive or prolonged breathing of fuel vapor can cause serious illness and permanent injury.
• Avoid getting fuel in your eyes. If you splash fuel in your eyes, immediately remove contact lenses, if worn, flush with water for 15 minutes and seek medical attention. Failure to seek proper medical attention could lead to permanent injury.
• Fuels can be harmful if absorbed through the skin. If you splash fuel on your skin, clothing or both, promptly remove contaminated clothing and thoroughly wash your skin with soap and water. Repeated or prolonged skin contact causes skin irritation.
• Be particularly careful if you are taking Antabuse or other forms of Disulfiram for the treatment of alcoholism. Breathing fuel vapors could cause an adverse reaction, serious personal injury or sickness. Immediately call a physician if you experience any adverse reactions.
