Driver Efficiency Gauge
The driver efficiency gauge assists you in driving efficiently. 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 accelerating 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.
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 high-
est 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.
Regenerative Braking
When braking or coasting, the electric motor acts like a generator to charge the high-
voltage battery. This "regenerative braking" process captures kinetic 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.
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.
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.
