Starting and Operating

New Vehicle Break-In

Caution
Follow these recommended guidelines during the first 2 414 km (1,500 mi) of driving this vehicle. Parts have a break-in period and performance will be better in the long run.

• Avoid full-throttle starts and abrupt stops.
• Do not exceed 4000 engine rpm.
• Avoid driving at any one constant speed, fast or slow.
• Do not drive above 129 km/h (80 mph).
• Avoid downshifting to brake or slow the vehicle when the engine speed exceeds 4000 rpm.
• Do not let the engine labor. Never lug the engine in high gear at low speeds. With a manual transmission, shift to the next lower gear. This rule applies at all times, not just during the break-in period.
• Check engine oil with every refueling and add if necessary. Oil and fuel consumption may be higher than normal during the first 2 414 km (1,500 mi).
• To break in new tires, drive at moderate speeds and avoid hard cornering for the first 322 km (200 mi).
• New tires do not have maximum traction and may tend to slip.
• New brake linings also need a break-in period. Avoid making hard stops during the first 322 km (200 mi). This is recommended every time brake linings are replaced.
• Should the vehicle be used for racing or competitive driving (after the break-in), the rear axle lubricant must be replaced beforehand.

On new vehicles, the various mechanical and electrical systems experience a “break-in” period during the first 6,400 km (4,000 miles) of routine driving. As the vehicle is driven, the mechanical systems adjust to provide optimal fuel economy and transmission shift performance. Electrical systems will adapt and calibrate during the break-in period. A one-time occurrence of clicks and similar vehicle noises is normal during this process. Normal driving charges the vehicle’s battery to achieve the best operation of the vehicle, including fuel economy.

Composite Materials
This vehicle may be equipped with parts containing carbon fiber, sheet-molding compound, or other composite materials. Dealer-installed accessories may also contain composite materials.

Warning
Exposed edges of parts containing carbon fiber and other composite materials can be sharp. Contact with these parts could result in injury. Use caution to avoid contacting these parts, including when washing the vehicle. If the parts are damaged, replace the parts promptly with replacements from your dealer.

Warning
Rocker extensions may break under pressure, resulting in property damage or injury. Do not stand on the rocker extension or use it as a step.

Warning
Rear-end spoilers may break under pressure, resulting in property damage or injury. Do not push the vehicle by the spoiler or use the spoiler as a handle.

Ignition Positions

The vehicle has an electronic keyless ignition with a pushbutton start. The remote key must be in the vehicle for the system to operate. If the pushbutton start is not working, the vehicle may be near a strong radio antenna signal causing interference to the remote key system. To shift out of P (Park), the vehicle must be on and the brake pedal must be applied.

Stopping the Engine/LOCK/OFF (No Indicator Lights): When the vehicle is stopped, press ENGINE START/STOP once to turn the engine off. If the vehicle is in P (Park), the ignition will turn off, and Retained Accessory Power (RAP) will remain active. The vehicle may have an electric steering column lock. The lock is activated when the vehicle is switched to OFF and the driver’s door is opened. A sound may be heard as the lock actuates or releases. The steering column lock may not release with the wheels turned off center. If this happens, the vehicle may not start. Move the steering wheel from left to right while attempting to start the vehicle. If this does not work, the vehicle needs service. Do not turn the engine off when the vehicle is moving. This will cause a loss of power assist in the brake and steering systems and disable the airbags.

If the vehicle must be shut off in an emergency:

1. Brake using firm and steady pressure. Do not pump the brakes This may deplete power assist, requiring increased brake pedal force.
2. Shift the vehicle to N (Neutral). This can be done while the vehicle is moving. After shifting to N (Neutral), firmly apply the brakes and steer the vehicle to a safe location.
3. Come to a complete stop and shift to P (Park).
4. Set the parking brake. 

Warning
Turning off the vehicle while moving may cause loss of power assist in the brake and steering systems and disable the airbags. While driving, only shut the vehicle off in an emergency. If the vehicle cannot be pulled over, and must be shut off while driving, press and hold ENGINE START/STOP for longer than two seconds, or press twice in five seconds.

Accessory Mode (Amber Indicator Light)
This mode allows some electrical accessories to be used when the engine is off. With the ignition off, pressing the button one time without the brake pedal applied will place the ignition system in accessory mode. The ignition will switch from accessory mode to off after five minutes to prevent battery rundown.

ON/RUN/START (Green Indicator Light)
This mode is for driving and starting. With the ignition off, and the brake pedal applied, pressing the button once will place the ignition system in ON/RUN/START. Once engine cranking begins, release the button. Engine cranking will continue until the engine starts. 

Service Mode
This power mode is available for service and diagnostics, and to verify the proper operation of the malfunction indicator lamp as may be required for emission inspection purposes. With the vehicle off, and the brake pedal not applied, pressing and holding the button for more than five seconds will place the vehicle in Service Mode. The instruments and audio systems will operate as they do in ON/RUN, but the vehicle will not be able to be driven. The engine will not start in Service Mode. Press the button again to turn the vehicle off.

Starting the Engine
Place the transmission in the proper gear.

Caution
If you add electrical parts or accessories, you could change the way the engine operates. Any resulting damage would not be covered by the vehicle warranty.

Automatic Transmission
Move the shift lever to P (Park) or N (Neutral). To restart the vehicle when it is already moving, use N (Neutral) only.

Caution
Do not try to shift to P (Park) if the vehicle is moving. If you do, you could damage the transmission. Shift to P (Park) only when the vehicle is stopped.

Manual Transmission
The shift lever should be in Neutral and the parking brake engaged. Hold the clutch pedal down to the floor, press the brake pedal, and start the engine.

Starting the Vehicle

1. For vehicles with an automatic transmission, press the brake pedal, then press ENGINE START/STOP on the instrument panel. For a manual
   transmission, place the shift lever in Neutral with the parking brake engaged. Hold the clutch pedal down to the floor, press the brake pedal, then press ENGINE START/STOP. If the remote key is not in the vehicle, if there is interference, or if the remote key battery is low, a Driver Information Center (DIC) message will display. 
   Caution
   Cranking the engine for long periods of time, by pressing the ENGINE START/STOP immediately after cranking has ended, can overheat and damage the cranking motor, and drain the battery. Wait at least 15 seconds between each try, to let the cranking motor cool down.
2. If the engine does not start after five to 10 seconds, especially in very cold weather (below −18 °C or 0 °F), it could be flooded with too much gasoline. Try pushing the accelerator pedal all the way to the floor and hold it there, then press ENGINE START/STOP for up to a maximum of 15 seconds. Wait at least 15 seconds between each try, to allow the cranking motor to cool down. When the engine starts, let go of the button and the accelerator. If the vehicle starts briefly but then stops again, do the same thing. This clears the extra gasoline from the engine. Do not race the engine immediately after starting it. Operate the engine and transmission gently until the oil warms up and lubricates all moving parts.

Stopping the Engine
If the vehicle has an automatic transmission, move the shift lever to P (Park) and press and hold ENGINE START/STOP on the instrument panel, until the engine shuts off. If the shift lever is not in P (Park), the engine shuts off and the ignition goes to accessory mode. The DIC displays SHIFT TO PARK. Once the shift lever is moved to P (Park), the vehicle turns off. If the vehicle has a manual transmission, before getting out of the vehicle, shift to 1 (First) or R (Reverse) and apply the parking brake. Then turn off the ignition off by pressing ENGINE START/STOP and release the clutch pedal when the engine has stopped. If the remote key is not detected inside the vehicle when it is turned off the DIC displays a message.

Stop/Start System
If equipped, the Stop/Start system will shut off the engine to help conserve fuel. It has components designed for the increased number of starts.

Warning
The automatic engine Stop/Start feature causes the engine to shut off while the vehicle is still on. Do not exit the vehicle before shifting to P (Park). The vehicle may restart and move unexpectedly. Always shift to P (Park), and then turn the ignition off before exiting the vehicle.

Auto Engine Stop/Start
When the brakes are applied and the vehicle is at a complete stop, the engine may turn off. When stopped, the tachometer displays AUTO STOP. When the brake pedal is released or the accelerator pedal is pressed, the engine will restart. To maintain vehicle performance, other conditions may cause the engine to automatically restart before the brake pedal is released.

Auto Stops may not occur and/or auto restarts may occur because:

• The climate control settings require the engine to be running to cool or heat the vehicle interior.
• The vehicle battery needs to charge.
• The vehicle battery has recently been disconnected.
• Minimum vehicle speed has not been reached since the last Auto Stop
• The accelerator pedal is pressed.
• The engine or transmission is not at the required operating temperature.
• The outside temperature is not in the required operating range.
• The transmission is shifted out of D (Drive) to any gear other than P (Park).
• Certain driver modes have been selected.
• The vehicle is on a steep hill or grade.
• The driver door has been opened or driver seat belt has been unbuckled.
• The hood has been opened.
• The Auto Stop has reached the maximum allowed time.

Auto Stop/Start Disable Switch

Engine Heater
The engine heater can provide easier starting and better fuel economy during engine warm-up in cold weather conditions at or below −18 °C (0 °F). Vehicles with an engine heater should be plugged in at least four hours before starting. An internal thermostat in the plug-end of the cord may exist, which will prevent engine heater operation at temperatures above −18 °C (0 °F).

Warning
Do not plug in the engine block heater while the vehicle is parked in a garage or under a carport. Property damage or personal injury may result. Always park the vehicle in a clear open area away from buildings or structures.

To Use the Engine Heater

1. Turn off the engine.
2. Inspect the heater cord for damage before each use. If it is damaged, do not use it. See your dealer for a replacement.
3. Plug the heater cord into the connector in the front license plate bracket
4. Plug it into a normal, grounded 110-volt.
   Warning
   Improper use of the heater cord or an extension cord can damage the cord and may result in overheating and fire.
   • Plug the cord into a three-prong electrical utility receptacle that is protected by a ground fault detection function. An ungrounded outlet could cause an electric shock.
   • Use a weatherproof, heavy-duty, 15 amp-rated extension cord if needed. Failure to use the recommended extension cord in good operating condition, or using a damaged heater or extension cord, could make it overheat and cause a fire, property damage, electric shock, and injury.
   • Do not operate the vehicle with the heater cord permanently attached to the vehicle. Possible heater cord and thermostat damage could occur.
   • While in use, do not let the heater cord touch vehicle parts or sharp edges.
5. Before starting the engine, be sure to unplug and store the cord as it was before to keep it away from moving engine parts. If you do not, it could be damaged.

Contact your dealer for information on how long to use the heater in your particular area.
