Press to select a setting of Far, Medium, or Near.
Cancel
Press to cancel the cruise control without erasing the set speed from me\
mory.
Pressing the brake pedal also will cancel the cruise control.
The cruise control set speed is erased when cruise control or the vehicl\
e ignition is turned off.
See Driving and Operating in your Owner Manual.
Setting Cruise Control
1. Press the On/Off button (or button if equipped with Adaptive Cruise ControlF). The Cruise Control symbol will illuminate in white on the instrument cluster.
2. When traveling at the desired speed, press the switch down to the SET–
position to set the speed. The symbol will illuminate in green on the instrument cluster.

Automatic Transmission
StabiliTrak®/Traction Control Systems
The traction control system limits wheelspin and the StabiliTrak electro\
nic stability control system assists with directional control of the vehicle in difficult driving conditions. Both
systems turn on automatically every time the vehicle is started.
Driver Shift Control
Driver Shift Control allows the driver to shift gears manually. This feature can be used to drive the vehicle in a sportier manner or to downshift when driving on a\
downhill grade to provide engine braking.
Move the shift lever to the left of the Drive (D) position. Tap the shift lever forward (+) to upshift or rearward to downshift (–). The currently selected gear will be displayed on the instrument cluster.
If vehicle speed is too high or too low for the requested gear, the shift will not occur. When coming to a stop, the transmission will automatically downshift.
See Driving and Operating in your Owner Manual.
Turning Off Traction Control
Turn off traction control if the vehicle is stuck and rocking the vehicle is required.
Press the StabiliTrak/Traction Control button on the top center of the instrument panel to turn the system on/off. The Traction Control Off light will illuminate on the instrument cluster when the system is off.
See Driving and Operating in your Owner Manual.
Electric Parking Brake
To apply the parking brake, pull up the Parking Brake switch by the shift lever.
To release the parking brake, turn on the ignition, press the brake pedal and press down the Parking Brake switch.

eAssist Overview (if equipped)
A compact electric assist system called eAssist has been integrated with the highly efficient 2.4-liter four-cylinder engine and six-speed automatic transmission to provide an electric “boost” to help conserve fuel. eAssist includes a small, but powerful, electric motor rated at 15 kilowatts. It replaces the typical alternator found on most engines. \
eAssist also uses a small, advanced 115-volt lithium-ion battery located in the trunk.
eAssist Features
Auto Start/Stop
While driving, when the brake is applied and the vehicle comes to a complete stop, the automatic engine start/stop system may turn off the engine, referred to \
as an Auto Stop. In Auto Stop mode, the tachometer gauge will read AUTO STOP. The audio syst\
em, climate controls and other accessories will be powered by the high-voltage battery. The engine will restart immediately when the brake pedal is released or the accelerator pedal is applied.
After parking the vehicle and turning off the engine, the tachometer gauge will read OFF.
There are several conditions that may cause the engine to remain running or restart when the vehicle is stopped.
• The engine, transmission or high-voltage battery is not at the required operating temperature.
• The outside temperature is less than –4º F (–20º C).
• The shift lever is in any gear other than Drive (D).
• The high-voltage battery state of charge is low. It will automatically recharge as the vehicle is driven.
• The climate control system requires the engine to run based on the clima\
te control or defog setting. Using the eco Air Conditioning mode will result in more f\
requent and
longer Auto Stops than the Comfort Air Conditioning mode.
• The Auto Stop time is greater than two minutes.
See Driving and Operating in your Owner Manual.
Power Flow Display
The Power Flow display, located on the infotainment system touch screen, indicates the current eAssist operating mode, energy flow direction and high voltage battery charge level. The operating modes include Engine Idle, Auto Stop, Engine Power,\
Hybrid Power, and Regen Recovery.
See Instruments and Controls in your Owner Manual.

Driver Efficiency Gauge
The driver efficiency gauge, located on the instrument cluster, assists you in driving effi-ciently. To maximize efficiency, attempt to keep the pointer in the solid green zone in the middle of the gauge. The gauge moves down when braking and up when accel\
erating or driving at high speeds. When
driving aggressively, it is less efficient and the gauge will move farther away from center. The eAssist system’s ability to capture energy while the vehicle is slowing down makes decelerating important for vehicle efficiency.
See Instruments and Controls in your Owner Manual.
Climate Control Settings
Press the A/C button twice to select the eco Air Conditioning setting (green A/C indica-tor) for maximum efficiency. This setting will maximize the frequency and duration of Auto Stops while still providing cabin comfort when the vehicle is in an Auto Stop. To
further maximize efficiency, operate the climate controls in the Automatic mode at the
highest comfortable temperature setting or turn off the air conditioning system when climate conditions allow.
Select the Comfort Air Conditioning setting (amber A/C indicator) for maximum cabin
comfort. Auto Stops will be reduced in both frequency and duration.
See Climate Controls in your Owner Manual.
Regenerative Braking
When braking or coasting, the electric motor acts like a generator to ch\
arge the high-voltage battery. This “regenerative braking” process captures kine\
tic energy that would otherwise be lost and stores it in the high-voltage battery. This electrical energy can then be reused.
Note: Capturing kinetic energy causes transmission shifts that have more feel when braking or coasting.
See In Brief in your Owner Manual.
Next Generation Transmission
The eAssist system employs a next generation six-speed transmission with sophisticated algorithms that continuously store information about your driving style, such as acceleration and braking. Over the first 250–400 miles, some transmission shifts may be more notice-able. As the vehicle is driven in a variety of city and highway driving conditions, eAssist will use its on-board processing power to quickly “learn” your driving habits in order to deliver a seamless driving experience.
See Driving and Operating in your Owner Manual.
Hill Start Assist
After stopping on an incline, the Hill Start Assist feature momentarily holds the vehicle when the brake pedal is released. The driver-applied brake pressure is used during the stop to keep the vehicle from rolling during the period between when the\
brake pedal is released and the accelerator pedal is applied.
See Driving and Operating in your Owner Manual.
